The support rod 122 is fixedly installed on one side of the support plate 121 and the first threaded rod 123 is rotatably installed. One end of the support rod 122 slides through the support plate 121 and extends to the outside. One end of the first threaded rod 123 is threaded through the support plate 121 and fixedly installed on the turntable 124. The second bracket 125 is fixedly installed on both sides of the support plate 121. The second bracket 125 is L-shaped, and pulleys 126 are installed on both sides of the inner wall of the second bracket 125. The first bracket 120 is U-shaped. There are two support rods 122 and they are symmetrically arranged on both sides of the first threaded rod 123, and the support assemblies on both sides are symmetrically arranged to facilitate the device to slide on the track through the pulley 126.

[0022] See also Figure 3 and Figure 5 The lifting assembly includes a first pull rod 150, a second pull rod 151 and a cylinder 152. The first pull rod 150 is symmetrically hinged on both sides of the first support block 130, and the second pull rod 151 is symmetrically hinged on both sides of the second support block 132. One end of the two first pull rods 150 and the two second pull rods 151 on each side are symmetrically hinged to the side plates 153. One side of one side plate 153 is symmetrically fixed with the cylinder 152. The output end of the cylinder 152 is fixedly connected to one side of the other side plate 153.

[0025] Working principle: When in use, lift the support frame 110 above the track, and make the pulley 126 on the top of the inner wall of the second bracket 125 support and slide on the track. At this time, rotate the turntable 124 to drive the first threaded rod 123 to rotate. The first threaded rod 123 rotates through the support plate 121 to drive the second bracket 125 to move so that another pulley 126 on the inner wall of the second bracket 125 is squeezed and fitted with the side wall of the slide rail. At this time, the device can be pushed to move on the rail to change sleepers. When moving to the working place, you can first slightly tilt the two sides of the track and push the gravel to both sides. At this time, start the cylinder 152 to extend and retract through the side plates 153, the first pull rod 150 and the second pull rod 151 to drive the second support block 132 to move to the output of the pneumatic finger 134 When the end of the rail reaches both sides of the sleeper, the pneumatic fingers 134 are started to clamp the sleeper. At this time, the cylinder 152 is started again to drive the sleeper to rise. At the same time, the second motor 160 is started to drive the support plate 133 to rotate through the second telescopic rod 162. The rotation of the support plate 133 drives the sleeper to rotate between the two sides of the track through the pneumatic fingers 134 for easy lifting and removal. Finally, the first motor 143 is started to drive the second threaded rod 141 to rotate. The rotation of the second threaded rod 141 drives the first support block 130 to move through the slider 140 to move the sleeper out of the track. In the removal method, the sleeper can also be clamped and fixed and then the first motor 143 is directly started to cooperate with the pneumatic fingers 134 to move it out. When replacing, the new sleeper can be installed in the same steps as the above disassembly method.
