[0040] Furthermore, the moving component 303 includes a second groove 303a arranged on the inner side wall of the first sliding groove 301a, a connecting groove 303b is opened on the inner side wall of the second groove 303a, a pushing groove 303c is opened on the inner side wall of the connecting groove 303b, and an L-shaped plate 303d is slidably connected in the connecting groove 303b; the pushing component 304 includes a third sliding groove 304a arranged on the side wall of the L-shaped plate 303d, a slider 304b is slidably connected in the third sliding groove 304a, and a pushing seat 304c is fixedly connected to the side wall of the slider 304b A third groove 304d is formed on the inner side wall of the pushing groove 303c, and a third spring 304e is fixedly connected to the inner side wall of the third groove 304d; wherein the third spring 304e is fixedly connected to the side wall of the pushing seat 304c; the guide assembly 305 includes a first guide groove 305a arranged on the inner side wall of the pushing groove 303c, a second guide groove 305b is arranged in the first guide groove 305a, a third guide groove 305c is arranged in the second guide groove 305b, and a guide block 305d is fixedly connected to the side wall of the pushing seat 304c.

The U-shaped block 302a drives the first rotating column 302b and the third rotating plate 302f to move with the extrusion seat 301d. Since the third rotating plate 302f is slidably connected to the first rotating plate 302d, the third rotating plate 302f moves away from the groove. When the cover plate moves in the direction of rotation, the first rotating plate 302d will drive the second rotating post 302c and the first rotating plate 302d to deflect counterclockwise with the second rotating post 302c as the center of the circle along with the third rotating plate 302f. Since the L-shaped plate 303d is in contact with the second rotating plate 302e, when the second rotating plate 302e deflects counterclockwise with the second rotating post 302c as the center of the circle, the L-shaped plate 303d will be pushed to move, so that the L-shaped plate 303d pushes the pushing seat 304c to move between the second groove 303a, the connecting groove 303b and the pushing groove 303a. 3c moves away from the first slide groove 301a, at this time, the guide block 305d slides from the first guide groove 305a, the second guide groove 305b to the third guide groove 305c along with the pushing seat 304c, and under the cooperation of the guide block 305d, the first guide groove 305a, the second guide groove 305b, the fourth guide groove, the third slide groove 304a and the slider 304b, the pushing seat 304c gradually moves upward in the pushing groove 303c to squeeze the slide seat 201c, so that the slide seat 201c presses the fixed The fixed plate 201d, the fixed pad 202a and the anti-slip protrusion 202c apply an extrusion force to firmly fix the trench cover plate in the U-shaped hole in the U-shaped seat 101, thereby playing a reinforcing role, further preventing the trench cover plate from sliding in the U-shaped seat 101, and further preventing the trench cover plate from sliding off the U-shaped seat 101, thereby further improving safety. At the same time, the fixed pad 202a acts as a buffer to prevent the applied extrusion force from acting entirely on the trench cover plate and causing damage to the trench cover plate, thereby further ensuring that the removed old trench cover plate can be reused.

[0043] In summary, in combination with Example 1, and through the cooperation of the extrusion component 301, the rotation component 302, the movement component 303, the pushing component 304 and the guide component 305, a reinforcement effect can be achieved to firmly fix the trench cover plate in the U-shaped hole in the U-shaped seat 101, further preventing the trench cover plate from sliding in the U-shaped seat 101, and further preventing the trench cover plate from sliding off the U-shaped seat 101, thereby achieving the effect of further improving safety.

[0046] Specifically, two limit assemblies 401 are provided, and the two limit assemblies 401 are symmetrically arranged, the fourth groove 401a is connected to the adjustment groove 105, the limit seat 401c is slidably connected to the fourth groove 401a, the first inclined surface 401d is adapted to the third inclined surface 401g, and the second inclined surface 401e is adapted to the fourth inclined surface 401h. The adjustment seat 106 can be limited by the limit seat 401c and the limit groove 401f, so that the distance between the two groups of U-shaped seats 101 can be quickly limited and fixed after the adjustment, to prevent the wire rope from being subjected to force when lifting with external equipment, so as to change the distance between the two groups of U-shaped plates.

[0047] Furthermore, the limiting component 402 includes a fourth slide groove 402a arranged in the adjustment seat 106, a through slide groove 402b is opened on the side wall of the U-shaped seat 101, a fifth groove 402c is opened on the side wall of the adjustment seat 106, the inner wall of the fourth slide groove 402a is slidably connected with a limiting seat 402d, and the inner wall of the adjustment groove 105 is opened with a limiting groove 402e; wherein, the fifth groove 402c is connected to the fourth slide groove 402a, and the limiting seat 402d is plug-connected with the limiting groove 402e.

During adjustment, it is only necessary to apply tension to one group of U-shaped seats 101 to make the adjusting seat 106 squeeze the limiting seat 401c, so that the two limiting seats 401c move away from each other and disengage from the limiting groove 401f under the action of the second inclined surface 401e, the fourth inclined surface 401h and the fourth groove 401a, thereby releasing the limit on the adjusting seat 106. At this time, the adjusting seat 106 can move in the direction away from the connecting seat 104 under the action of the adjusting groove 105, and when the corresponding limiting groove 401f corresponds to the position of the limiting seat 401c, the limiting seat 401c will be quickly inserted into the corresponding limiting groove 401f under the action of the fourth spring 401b, completing the limit on the adjusting seat 106, preventing the steel wire rope from being subjected to force when hoisting with external equipment, thereby preventing the distance between the two groups of U-shaped plates from changing. , and then the trench cover is located in the U-shaped seat 101. Similarly, under the action of the first inclined surface 401d, the third inclined surface 401g and the fourth groove 401a, the adjusting seat 106 can also move back, so as to adjust the distance between the two groups of U-shaped seats 101 according to the thickness of the trench cover, so as to maintain balance when lifting the trench cover, and further improve safety. In conjunction with Example 2, when the extrusion seat 301d is squeezed to slide into the first slide groove 301a, the corresponding extrusion seat 301d will drive the limiting seat 402d to move in the direction of the limiting groove 402e under the action of the fourth slide groove 402a, the fifth groove 402c and the through slide groove 402b. When the extrusion seat 301d is completely retracted into the first slide groove 301a, the limiting seat 402d is inserted into the corresponding limiting groove 402e to limit the adjusting seat 106 and the connecting seat 104, effectively preventing the distance between the two groups of U-shaped plates from changing, and improving the stability of the trench cover removal.

[0050] In summary, in combination with Example 1 and Example 2, and through the cooperation of the limit component 401 and the limiting component 402, it is convenient to adjust the distance between the two groups of U-shaped seats 101 according to the thickness of the trench cover and fix them in time to better maintain balance, and at the same time prevent the distance between the two groups of U-shaped seats 101 from changing when the trench cover is removed, thereby achieving the effect of further improving safety and improving the stability of trench cover removal.
