[0030] In one embodiment, Figure 1-Figure 7 As shown, an intelligent moving device for small trench cover plates includes a workbench 1, a clamping assembly, a centering assembly, and an extension assembly. An extension plate groove is provided on the side wall of the workbench 1, and an extension plate 12 is slidably connected to the inner side wall of the extension plate groove.

The extension assembly is arranged in the workbench 1, and is used to increase the width of the mobile device. The centering assembly is arranged on the upper surface of the workbench 1, and is used to make the moving block 7 located in the middle position of the workbench 1. The device is moved to the position where the cover plate needs to be carried by the moving wheels 3.

[0031] In one embodiment, Figure 2 As shown, a counterweight 5 is fixedly connected to the upper surface of the workbench 1 to prevent the device from tipping over during the process of carrying the cover plate.

[0032] In one embodiment, Figure 4 As shown, the extension assembly includes a first motor 4 and a threaded rod 13. The inner side wall of the extension plate groove is rotatably connected with the threaded rod 13 through a bearing. The threaded rod 13 is threadedly connected to the extension plate 12. The side wall of the workbench 1 opposite to the extension plate 12 is fixedly connected with the first motor 4 through a bracket. The output end of the first motor 4 is fixedly connected with the threaded rod 13. When the first motor 4 is started, the first motor 4 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the extension plate 12 to move, so that the extension plate 12 and the workbench 1 are extended to both sides, so that the mobile device can be extended according to cable trenches of different widths, and it is more convenient to place the cover plate in the cable trench. When the mobile device is not in working state, the extension plate 12 can be stored, which saves more space and allows the device to pass through narrower places.

A moving block groove is provided on the upper surface of the workbench 1, and the moving block 7 is slidably connected with the inner side walls of the moving block groove. When the workbench 1 and the extension plate 12 move to both sides, the damping springs in the two centering tubes 15 are in a compressed state, and the two damping springs have the same elastic coefficient. When the fixed block 14 moves, the damping springs in the two centering tubes 15 will drive the moving block 7 to move along the moving block groove to maintain balance, so that the moving block 7 is always in the middle position, which is more convenient for the crane arm 8 to carry the cover plate.

[0034] In one embodiment, Figure 5 As shown, the clamping assembly includes a second motor 11, a bidirectional screw 16, and a slider 17. A slider groove is provided on the lower surface of the lifting plate 10. The inner side wall of the slider groove is rotatably connected with a bidirectional screw 16 through a bearing.

The output end of the second motor 11 is fixedly connected to the bidirectional screw 16. When the cover plate needs to be transported, the second motor 11 is started, the second motor 11 drives the bidirectional screw 16 to rotate, the bidirectional screw 16 drives the two sliders 17 to move toward each other, the slider 17 drives the two clamping blocks 18 to move toward each other, and the clamping blocks 18 clamp and transport the cover plate. Compared with manual transportation, it is more time-saving and labor-saving, has high transportation efficiency, is not easy to cause injuries, and only requires one person to operate, saving a lot of human resources.

[0035] In one embodiment, Figure 7 As shown, the cross section of the slider 17 is T-shaped. The slider 17 can be limited.

[0036] In one embodiment, Figure 6As shown, the two clamping blocks 18 have first lifting block grooves and extrusion block grooves on the opposite side walls, the first lifting block grooves have first lifting blocks 19 slidably connected to the inner side walls, a damping spring is fixedly connected between the first lifting block 19 and the inner side walls of the first lifting block grooves, and the two clamping blocks 18 have second lifting block cavities, the first lifting block grooves and the extrusion block grooves are connected through the second lifting block cavities, the inner side walls of the second lifting block cavities are slidably connected to the second lifting block 21, and the second lifting block 21 is connected to the first lifting block 19. The extrusion block 20 is fixedly connected, and the extrusion block 20 is slidably connected to the inner side wall of the extrusion block groove. The side wall of the extrusion block 20 is provided with an inclined surface. The end of the second lifting block 21 away from the first lifting block 19 is provided with a chamfer. The end of the second lifting block 21 away from the first lifting block 19 abuts against the inclined surface of the extrusion block 20. The inner side wall of the extrusion block groove is provided with a convex block groove. The side wall of the extrusion block 20 is fixedly connected with a convex block 22. The convex block 22 is slidably connected to the inner side wall of the convex block groove. A damping spring is fixedly connected between the convex block 22 and the inner side wall of the convex groove. When the clamping block 18 clamps and lifts the cover plate, when the cover plate begins to slide down due to its own gravity, the first lifting block 19 is driven to slide down by friction, and the first lifting block 19 drives the second lifting block 21 to slide down. One end of the second lifting block 21 cooperates with the inclined surface of the extrusion block 20 to squeeze the extrusion block 20 out of the extrusion block groove, and the cover plate is squeezed. The cover plate is fixed for a second time by its own gravity, so that the cover plate is more stable to carry and not easy to fall and be damaged between the two clamping blocks 18.

[0037] Example 2

[0038] In one embodiment, Figure 6 As shown, the side wall of the first lifting block 19 outside the first lifting block groove is provided with an anti-skid rubber pad. Since the side wall of the first lifting block 19 is provided with an anti-skid rubber pad, the friction between the first lifting block 19 and the cover plate is increased.

[0039] The above embodiment discloses an intelligent moving device for small trench cover plates, firstly the device is moved to the position where the cover plate needs to be moved by the moving wheels 3;

[0040] The first motor 4 is started, and the first motor 4 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the extension plate 12 to move, so that the extension plate 12 and the workbench 1 are expanded to both sides. The mobile device can be expanded according to the cable trenches of different widths, which makes it more convenient to place the cover plate in the cable trench. When the mobile device is not in the working state, the extension plate 12 can be stored, which saves more space and allows the device to pass through narrower places;

[0041] When the workbench 1 and the extension plate 12 move to both sides, the damping springs in the two center tubes 15 are in a compressed state, and the two damping springs have the same elastic coefficient. When the fixed block 14 moves, the damping springs in the two center tubes 15 drive the moving block 7 to move along the moving block slot to maintain balance, so that the moving block 7 is always in the middle position, which is more convenient for the crane arm 8 to carry the cover plate;

[0042] When the cover plate needs to be transported, the second motor 11 is started, the second motor 11 drives the bidirectional screw 16 to rotate, the bidirectional screw 16 drives the two sliders 17 to move toward each other, the sliders 17 drive the two clamping blocks 18 to move toward each other, and the clamping blocks 18 clamp and transport the cover plate. Compared with manual transport, it is more time-saving and labor-saving, has high transport efficiency, is not easy to cause injuries, and only needs one person to operate, saving a lot of human resources;

[0043] When the clamping block 18 is clamping and lifting the cover plate, since the side wall of the first lifting block 19 is provided with an anti-skid rubber pad, the friction between the first lifting block 19 and the cover plate is increased. When the cover plate starts to slide down due to its own gravity, the first lifting block 19 is driven to slide down by friction, and the first lifting block 19 drives the second lifting block 21 to slide down. One end of the second lifting block 21 cooperates with the inclined surface of the extrusion block 20 to squeeze the extrusion block 20 out of the extrusion block groove, and the cover plate is squeezed. The cover plate is fixed for a second time by its own gravity, so that the cover plate is more stable to carry and is not easy to fall and be damaged from between the two clamping blocks 18.

[0044] When the cover is transported to the location where the cover needs to be placed, the cover can be put down by simply rotating the second motor 11 in the reverse direction.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
