Specific embodiments

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] The embodiment of the present utility model discloses an integrated high-speed rail track slab tensioning device.

[0027] The present utility model provides an integrated high-speed rail track slab tensioning device as shown in Figures 1-4 which includes a clamping plate 1. A connecting plate 2 is slidably penetrated between two clamping plates 1. Both clamping plates 1 are arranged in an L shape, and a sliding groove for the connecting plate 2 to slide through is opened at the upper end of the side close to each other. A sliding sleeve 3 is slidably sleeved on the outer side of the clamping plate 1. A vertical plate 4 is fixedly arranged at the lower end of the outer wall of the sliding sleeve 3. A tensioning oil cylinder 5 is fixedly arranged on the outer wall of the vertical plate 4. A piston rod of the tensioning oil cylinder 5 is fixedly provided with a mounting plate 6. A pneumatic gripper 7 is fixedly arranged on the outer wall of the mounting plate 6;

[0028] A support rod 8 is fixedly arranged at the lower end of the side wall of one clamping plate 1. A first connecting block 9 is rotatably sleeved on the rod wall of the support rod 8. An adjusting and positioning mechanism is arranged between the first connecting block 9 and the other clamping plate 1.

[0029] Since the track slab needs to go through various processes during production and is finally placed on the ground for placement, at this time, the tensioning work starts. First, according to the specifications of the track slab, the distance between the two clamping plates 1 is adjusted, and the whole device is erected above the track slab, and the two clamping plates 1 are clamped on both sides of the track slab, and the positions of the two clamping plates 1 are fixed. Then, according to the position of the tensioning rod on the side of the track slab, the sliding sleeve 3 is moved, so that the sliding sleeve 3 moves horizontally on the clamping plate 1 and the connecting plate 2, and the pneumatic gripper 7 and the tensioning rod are located on the same straight line. Then, the pneumatic gripper 7 is started to clamp the tensioning rod. Immediately afterwards, the tensioning oil cylinder 5 is started, so that the tensioning oil cylinder 5 drives the mounting plate 6 and the pneumatic gripper 7 to move horizontally, thereby completing the tensioning work.

[0030] In order to fix the working position of the tensioning oil cylinder 5 when the pneumatic gripper 7 and the tension rod are on the same straight line, as Figures 1-2 and Figure 4 shown, a positioning rod 10 is slidably penetrated through the side of the sliding sleeve 3. A spring 11 is sleeved on the rod wall of the positioning rod 10. Both ends of the spring 11 are fixedly connected to the positioning rod 10 and the sliding sleeve 3 respectively. A plurality of spaced positioning holes for inserting and matching the positioning rod 10 are formed in the outer walls of the clamping plate 1 and the connecting plate 2. A pull ring 12 is hinged to the end of the positioning rod 10.

[0031] Before the sliding sleeve 3 moves, pull the pull ring 12 to pull out the positioning rod 10 from the positioning hole and stretch the spring 11. When the pneumatic gripper 7 and the tension rod are on the same straight line, release the pull ring 12. Under the elastic recovery of the spring 11, the positioning rod 10 rebounds and is inserted into the positioning hole again. At this time, the position of the tensioning oil cylinder 5 is fixed, and stable tensioning work can be carried out.

[0032] And in order to be able to fix the position between the two clamping plates 1 when the clamping plate 1 is arranged above the track slab, as Figures 1-2 shown, the adjusting positioning mechanism includes an internally threaded tube 13. The internally threaded tube 13 is fixedly connected to the first connecting block 9 and internally threaded with an adjusting screw rod 14. The end of the adjusting screw rod 14 is rotatably sleeved with a second connecting block 15. A rotating block 17 is fixedly sleeved at one end of the adjusting screw rod 14 close to the second connecting block 15. A positioning bolt 16 is threaded through between the second connecting block 15 and the clamping plate 1. A threaded hole for connecting and matching the positioning bolt 16 is formed at the lower end of one side of the clamping plate 1 close to the positioning bolt 16.

[0033] When the clamping plate 1 is erected above the track slab and the two clamping plates 1 are located on both sides of the track slab, the rotating block 17 can be rotated to make the adjusting screw rod 14 move horizontally while rotating relative to the second connecting block 15 and adjust the distance between the two clamping plates 1. When both clamping plates 1 are in extrusion contact with the side wall of the track slab, release the rotating block and screw the positioning bolt 16 into the threaded hole to complete the position fixing of the two clamping plates 1 and stable tensioning work can be carried out.

[0034] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
