SET FOR BIMODAL TRANSPORT

Description

[0001] The invention concerns a bimodal transport set for transferring loads on semi-trailers along railway lines.

[0002] The road-railway transport set presented in the German laying open invention description No. 3344513 comprises a rail bogie having two separate suspension and coupling systems by means of which two adjacent semi-trailers are supported and coupled. Every semi-trailer is supported on the bogie by means of independent suspension and coupling elements, causing bogie axles to be loaded unevenly in case the semi-trailers are of different weight or are loaded in a different way. It influences unfavourably on reliability of bogie running and by the same restricts speed of the railway set.

[0003] The set presented in the Polish patent specification No. 163407 (DE 3939384A1) comprises semi-trailers, each of them with one locking pin at the front end and one at the rear end and it is supported on a coupling member connected with the bogie by a ball-and-socket joint.

[0004] Use of a very wide coupling member necessary for ensuring of semi-trailer levelling or use of semi-trailers with very high rigidity of the frame are disadvantages of this solution.

[0005] The set for bimodal transport consists of at least two semi-trailers each of them having at the rear part of its frame a road running set of adjusted wheel position level and at the front part a king pin and bogie coupling pins at both sides, as well as of two end bogies equipped with one-sided coupling seats and at least one intermediate bogie equipped with two-sided coupling seats.

[0006] The essence of the invention is that the semi-trailer frame consists of at least two longitudinal members connected crosswise with an outside cross member at each end and with an inside cross member at some distance from the latter. Two coupling pins are symmetrically spaced on the underneath of each outside cross member near its ends. The inside cross member includes a centrally placed seat, which in preferred embodiment is in the form of a port situated along the longitudinal axis of the frame. Each outside cross member of the frame is offsetted upwards above the inside cross member seat in its central part. The frame is provided with two symmetrically spaced homing hooks at both sides near ends of the frame. It is, furthermore, open from underneath at each end between the outside cross member and the seat, while inside from above and at sides it is closed with a homing guard growing narrower at sides from the outside cross member and from the longitudinal member ends to the seat.

[0007] The intermediate rail bogie includes a lower adapter mounted in the bogie by a ball-and-socket joint. The lower adapter includes a carrying cross beam on which there are symmetrically spaced two coupling seats and a supporting bar centrally situated along the longitudinal axis of the bogie. Over the lower adapter there is situated an upper adapter connected with the latter by a ball-and-socket joint. The upper adapter includes a carrying cross beam on which there are symmetrically spaced two coupling seats and a supporting bar centrally situated along the longitudinal axis of the bogie. The lower and upper adapters are turned with their coupling seats and supporting bars in the directions opposite to each other. In the preferred solution the coupling seats of both adapters are situated on the same level. Each adapter includes a central support situated in the vertical longitudinal plane under a carrying beam, supported on spring slides mounted on the rail bogie. The supporting bars include homing mandrels near their ends placed at the same level. The carrying beams, however, are provided near their ends with horizontal extension arms equipped with slide plates mating with side spring slides of the running part of the rail bogie. The extension arms of one carrying beam are directed towards the other carrying beam. The slide plates are shaped as sectors of a ring having its centre at the vertical axis of the adapter ball-and-socket joints. The side spring slides are spaced symmetrically on the running part of the rail bogie in the vertical plane going through the vertical axis of the ball-and-socket joints.

[0008] The end rail bogie includes a ball-and-socket joint connected with a carrying cross beam including centrally situated supporting bar and two symmetrically spaced coupling seats, which together with supporting bar are turned in the direction opposite to the buffer beam. The buffer beam is connected with the carrying beam by a space frame. The carrying beam in the the preferred embodiment near its ends includes horizontal extension arms, each provided with a slide plate mating with a side spring slide of the running part of the rail bogie. The slide plates are shaped as a sector of a ring having its centre at the vertical axis of the ball-and-socket joint. The side spring slides are spaced symmetrically on the running part of the rail bogie in the vertical cross plane going through the vertical axis of the ball-and-socket joint. The supporting bar have a homing mandrel coming into its tapered ending. Sides of the space frame are provided with fixed to them spring roll supports supported on a base plate of the rail bogie.
Use of the set according to the invention gives the following advantages:

• alternative use of semi-trailers both in the road transport and on the railways;
• possible use of semi-trailers of different turning rigidity;
• decrease of transport costs, especially for long-distance transport;
• elimination of non-ecological automobile transport;
• increased transport safety and increased running speed because of uniformity of bogie load;
• symmetrical system of connecting elements of semi-trailers makes easy to combine the set;
• simplicity of construction.

The slide plates 217 and 218 are shaped as sectors of a ring having its centre at the vertical axis of the ball-and-socket joints 204 and 209. The side spring slides 219 and 220 are spaced symmetrically on the running part 203 in the vertical cross plane going through the axis of the ball-and-socket joints 204 and 209; the side spring slides 219 of the upper adapter 210 are placed nearer the ball-and-socket joints 204 and 209, while the side spring slides 220 of the lower adapter 202 are placed further from the joints so that their spacing corresponds to spacing of the extension arms 215 and 216. The coupling seats 206 and 212 of the adapters 202 and 210 are situated at the same level. The supporting arms 207 and 213 include the homing mandrels 208 and 214 situated at the same level. Each adapter 202 and 210 includes its central support 221 and 222 being under its carrying beam 205 and 211 in horizontal longitudinal plane and each central support 221 and 222 is supported on its central spring slide 223 and 224, mounted on the running part 203 of the bogie 200 through bracket 225 and 226 at its longitudinal axis. The adapters, lower 202 and upper 210 are of box construction welded from steel plates.

[0013] The end rail bogie 300 includes a coupling apparatus 301 connected with a running part 302 by a ball-and-socket joint 303. The apparatus consists of a carrying cross beam 304 connected by a space frame 305 with a buffer beam 306 provided with combined draw and buffing gear 307. On the carrying beam 304 there are two coupling seats 308 spaced symmetrically. Moreover the carrying beam 304 includes centrally situated supporting bar 309 having a homing mandrel 310 near its end coming into its tapered ending. The coupling seats 308 together with the supporting bar 309 are turned in the direction opposite to the buffer beam 306. The carrying beam 304 near its ends includes horizontal extension arms 311 directed towards the buffer beam 306, each equipped with a slide plate 312 mating with a side spring slide 313 of the running part 302 of the bogie 300. The slide plates 312 are shaped as sectors of a ring having its centre at the vertical axis of the ball-and-socket joint 303. The side spring slides 313 are spaced symmetrically on the running part 302 of the bogie 300 in the vertical cross plane going through the vertical axis of the ball-and-socket joint 303. Each side of the space frame 305 is provided with fixed to it a spring roll support 314 supported on the base plate 315 of the running part 302 of the bogie 300. The beam 304 is of box construction welded from steel plates.

[0014] Connection of the set elements consists in backing the semi-trailer 100 with a tractor, not shown on the drawing, towards the end rail bogie 300. The supporting bar 309 with its homing mandrel 310 is turned in the direction of the seat 110, orientating the coupling apparatus 301 horizontally and vertically. When coming close the mandrel 310 is located in the seat 110 and the coupling pins 108 comes into the suitable coupling seats 308, where they are locked with a locking mechanism not shown on the drawing. The homing hooks 111 serve to lead the coupling pins 108 exactly vertically in the last stage of coupling after touching the base surface of the coupling apparatus 301. Then the tractor is separated in the known way and the intermediate bogie 200 is rolled under the front of the semi-trailer so that the supporting bar 207 or 213 is introduced into the seat 110 of the semi-trailer 100 front till the moment the coupling pins 108 come into suitable coupling seats 206 or 212 and are locked. After coupling the semi-trailer with both bogies 200 and 300 the running wheels 104 are lifted up and locked at proper level above the track. The side spring slides 313 or 219 and 220 restrict lateral tilting of the semi-trailer 100 in relation to the rail bogie 200 and 300. The spring roll supports 314 maintain the end coupling apparatus 301 in a position horizontal in relation to the rail bogie 300. The slide plates 217 and 218 or 312 together with the side slides 219 and 220 or 213 enables rotation of the adapters 202 and 210 or the coupling apparatus 301 round the vertical axis going through the ball-and-socket joint 204 and 209 or 303. Repetition of the coupling operations makes possible to complete a train set.
