Technical Field
[0001] The present invention relates to safety equipment for a train platform and, more
particularly, to safety equipment for a train platform, equipped with a rope tension
adjustment unit that can uniformly adjust tension of ropes for allowing and preventing
movement of passengers.
Background Art
[0002] In general, safety equipment for a train platform is installed on a platform by which
trains pass to allow and prevent entrance and exit of passengers. Safety equipment,
as shown in FIG. 1, includes: a plurality of rope lifters 100 each having a body 110
that is installed at a predetermined position from the entrance to the exit of a platform
by which a train passes and having a block 120 vertically moved by a driving unit
disposed at a side inside or outside the body 110; and a rope 200 horizontally connecting
the blocks 120.
[0003] However, as shown in FIG. 2, tension of the rope 200 was adjusted by using a plurality
of bolts 130 vertically arranged in the blocks 120 in the related art, but it was
troublesome and inconvenient to adjust the tension in this way. In particular, it
was difficult to uniformly adjust and maintain the tension of the rope, so passengers
could easily open the rope and go in and out. Further, large numbers of bolts 130
and much rope 200 were used, so the efficiency of maintenance was low.
[0004] Further, as shown in FIG. 3, in the related art, a plurality of rollers 140 was vertically
arranged in a block 120, a rope 200 was provided to circulate around the rollers 140,
and a spring 141 was disposed inside the rope 200 to adjust tension. However, it was
difficult to appropriately adjust the tension in accordance with extension and contraction
of the rope 200 due to changes in season and temperature. In particular, since the
rope 200 has a length of tens to hundreds of meters, it was difficult to adjust the
tension of the rope 200 with only the spring 141 and there were constraints in function.

the safety equipment equipped with a rope tension adjustment unit disposed between
blocks that vertically move and sub-blocks connected by a rope that circulates to
uniformly adjust tension of the rope having a length of tens to hundreds of meters
by moving outward the sub-blocks.

Best Mode
[0016] Hereinafter, preferred embodiments of the present invention will be described with
reference to accompanying drawings.
[0017] Safety equipment for a train platform, equipped with a rope tension adjustment unit
according to the present invention is shown in FIGS. 4 to 6. FIG. 4 shows a first
embodiment, FIG. 5 shows a second embodiment, and FIG. 6 shows a third embodiment.
[0018] Safety equipment for a train platform, equipped with a rope tension adjustment unit
of the present invention includes: a plurality of rope lifters 100 each having a body
110 that is installed at a predetermined position from the entrance to the exit of
a platform by which a train passes and having a block 120 vertically moved by a driving
unit disposed at a side inside or outside the body 110; a rope 200 horizontally connecting
the blocks 120; and tension adjustment units 300 disposed between the blocks 120 and
sub-blocks 150, which are disposed inside the blocks 120 and connected by the rope
200 that circulates, to adjust tension of the rope 200 by moving outward the sub-blocks
150.
[0019] The operation principle and structure of the rope lifters 100 and the rope 200 are
well known in the art, so they are not described in detail.
[0020] Since the sub-block 150 is disposed inside the block 120, it is possible to adjust
the tension of the rope 200 by moving the entire sub-block 150 outside.
[0021] A plurality of rollers 151 are vertically arranged inside the sub-block 150 and one
rope 200 can connect the rollers while circulating in the entire equipment.
[0022] Accordingly, the block 120 can be vertically moved and the sub-block 150 can be moved
outside by operating the tension adjustment unit 300 with the rope 200 connected,
so it is possible to uniformly adjustment and maintain the tension of the rope 200
that has a length of tens to hundreds of meters in accordance with the movement distance
of the sub-block 150.
[0023] A first embodiment of the tension adjustment unit 300, as shown in FIG. 4, includes:
support shafts 310 each coupled to a first side of the block 120 and inserted in a
first side of the sub-block 150; and elastic members 320 each fitted on a second portion
of the support shaft 310 to move outward the sub-block 150.
[0024] The support shafts 310 smoothly guide the sub-block 150 that is moved left and right
by elasticity of the elastic members 320.
[0025] That is, first ends of the support shafts 310 are fixed to the first side of the
block 120 and second ends of the support shafts 310 are inserted in the first side
of the sub-block 150, so it is possible to uniformly adjust and maintain the tension
of the rope 200 by pushing the sub-block 150 outward using the elastic members 320.
[0026] With the second portions of the support shafts 310 in contact with the elastic members
320, it is possible to push outward the sub-block 150 using elasticity of the elastic
members 320.
[0027] A second embodiment of the tension adjustment unit 300, as shown in FIG. 5, includes:
support shafts 310 each coupled to a first side of the sub-block 150 and inserted
in a first side of the block 120; and elastic members 320 each fitted on a second
portion of the support shaft 310 to move outward the sub-block 150.
[0028] Accordingly, first ends of the support shafts 310 are fixed to the first side of
the sub-block 150 and second ends of the support shafts 310 are inserted in the first
side of the block 120, so it is possible to uniformly adjust and maintain the tension
of the rope 200 by pushing the sub-block 150 outward using the elastic members 320.
[0029] With the second portions of the support shafts 310 in contact with the elastic members
320, it is possible to moving the sub-block 150 can by pulling outward the support
shafts 310 using elasticity of the elastic members 320.
[0030] In the present invention, it is possible to uniformly adjust and maintain the tension
of the rope 200 by moving outward the sub-block 150 by using compression springs as
the elastic members 320.
[0031] The tension adjustment unit may further include moving members 311 thread-fastened
to the ends of the second portions of the support shafts 310 to increase compressive
force of the elastic members 320 by pushing the elastic members 320.
[0032] The moving members 311 may be nuts or other machined members to be thread-fastened
to the ends of the second portions of the support shafts 310.
[0033] Meanwhile, a third embodiment of the tension adjustment unit 300, as shown in FIG.
6, includes elastic members 330 disposed between the block 120 and the sub-block 150
to move outward the sub-block 150.
[0034] In this embodiment, it is possible to uniformly adjust and maintain the tension of
the rope 200 by moving outward the sub-block 150 by using extension springs as the
elastic members 330.
[0035] In the present invention, guide shafts 340 may be provided between the block 120
and the sub-block 150 not only to guide the sub-block 150 outward or inward by connecting
the block 120 vertically moving and the sub-block 150 moving outward for tension adjustment,
but to smoothly guide the block 120 and the sub-block 150 so that the block 120 and
the sub-block 150 are simultaneously vertically moved while the block 120 is vertically
moved.
[0036] The guide shafts 340 may be fixed to the first side of the block 120 and inserted
in the sub-block 150 or may be fixed to the first side of the sub-block 150 and inserted
in the block 120.
