DETAILED DESCRIPTION

[0016] Example 1 See also Figure 1-Figure 3 , this embodiment provides a cable trench cover disassembly device to improve the convenience of cover disassembly and assembly.

[0017] In this embodiment, the cable trench cover disassembly device includes a frame 10, a swing arm 20, an adjustment mechanism 30 and a driving mechanism 40, wherein a triangular support plate 11 is fixedly connected to the frame 10, a moving wheel 12 is provided on the support plate 11, a first angle steel 13 is provided at the front end of the frame 10, and the frame 10 as a whole can swing around the wheel axle of the moving wheel 12, thereby driving the first angle steel 13 to swing by utilizing the lever principle; connecting tubes 21 are provided on both sides of the swing arm 20, the connecting tube 21 is hinged to the support plate 11, a movable rod 22 is inserted inside the swing arm 20, and a second angle steel 23 is provided at the front end of the movable rod 22, the swing arm 20 as a whole is hinged between the two support plates 11 through the connecting tube 21, the swing arm 20 and the frame 10 as a whole are arranged at an obtuse angle, the swing arm 20 can overlap the first angle steel 13, the second angle steel 23 corresponds to the first angle steel 13, and the two are kept in parallel arrangement for clamping the cover of the cable trench.

[0018] The adjusting mechanism 30 is arranged as a whole on the connecting tube 21. The adjusting mechanism 30 is used to drive the movable rod 22 to slide in the swing arm 20. The adjusting mechanism 30 includes a screw rod 31 and an adjusting rod 33. The screw rod 31 is rotatably arranged inside the swing arm 20 as a whole and is screwed together with the movable rod 22. A first bevel gear 32 is provided on the screw rod 31; the adjusting rod 33 is rotatably arranged inside the connecting tube 21 as a whole. A second bevel gear 34 meshing with the first bevel gear 32 is provided at the inner end of the adjusting rod 33. The rotation of the adjusting rod 33 can drive the screw rod 31 to rotate, thereby driving the movable rod 22 to move inside the swing arm 20.

[0019] It should be noted that the swing arm 20 is constructed into a hollow rectangular tube, and the movable rod 22 is also constructed into a rectangle along the cross section. The movable rod 22 is adaptively inserted into the interior of the swing arm 20, and the plug-in cooperation between the two allows the movable rod 22 to only move along the longitudinal direction of the swing arm 20, limiting the rotation of the movable rod 22 inside the swing arm 20. Therefore, the rotation of the screw 31 can drive the movable rod 22 to move inside the swing arm 20.

[0020] The driving mechanism 40 is arranged as a whole at the outer end of the adjusting rod 33. The driving mechanism 40 is used to drive the adjusting rod 33 to rotate. The driving mechanism 40 includes a transmission wheel 41 and a mounting shell 42. The transmission wheel 41 is fixed to the outer end of the adjusting rod 33, and a card slot 411 is provided on the circumference of the transmission wheel 41. The extension direction of the card slot 411 is parallel to the axis of the adjusting rod 33. The card slots 411 are evenly distributed along the circumference of the transmission wheel 41. The transmission wheel 41 and the adjusting rod 33 are coaxially arranged, and the two rotate synchronously. The mounting shell 42 is rotatably sleeved on the outside of the transmission wheel 41. The mounting shell 42 is fixed by the positioning bolt 4 26 is locked on the adjusting rod 33, and the mounting shell 42 can rotate relative to the adjusting rod 33, a handle 421 is fixedly connected to the mounting shell 42, and a mounting cylinder 422 is also fixedly connected to the mounting shell 42, the mounting cylinder 422 is arranged along the radial direction of the transmission wheel 41, a limiting groove 423 is provided at the end of the mounting cylinder 422, the limiting groove 423 extends along the axial direction of the mounting cylinder 422, and two limiting grooves 423 are evenly arranged along the circumference of the mounting cylinder 422, an end cover 424 is also screwed on the end of the mounting cylinder 422, and a compression spring 425 is fixedly connected to the inside of the end cover 424.

[0021] The lever 43 is integrally inserted into the interior of the mounting tube 422, and a limiting rod 431 is provided at the outer end of the lever 43. The limiting rod 431 can be slidably inserted into the limiting groove 423, and the limiting rod 431 corresponds to the limiting groove 423 one by one. The compression spring 425 is compressed between the outer end surface of the lever 43 and the end cover 424. The inner end of the lever 43 includes a clamping portion 432 clamped with the clamping groove 411, and an arc-shaped guide surface 433 is provided on the rear side of the clamping portion 432. The lower end of the guide surface 433 is located in the clamping groove 411.

[0022] It should be noted that, under the push of the compression spring 425, the clamping portion 432 is clamped in the clamping slot 411. When the mounting shell 42 is driven to rotate counterclockwise by the handle 421, the clamping cooperation between the clamping portion 432 and the clamping slot 411 can drive the transmission wheel 41 to rotate synchronously, and then drive the adjusting rod 33 to rotate synchronously; when the mounting shell 42 is driven to rotate clockwise by the handle 421, the clamping cooperation between the guide surface 433 and the clamping slot 411 is utilized, and the lever 43 will retreat into the interior of the mounting tube 422 under the push of the edge of the clamping slot 411 until the clamping portion 432 is disengaged from the clamping slot 411. At this time, the clockwise rotation of the mounting shell 42 will not drive the transmission wheel 41 to rotate, that is, the lever 43 is configured to be allowed to push the transmission wheel 41 to rotate only in a single direction.

[0023] In this embodiment, the transmission wheel 41 can be driven to rotate in the counterclockwise direction by moving the handle 421 back and forth, and then the screw rod 31 can be driven to rotate through the adjusting rod 33, and the movable rod 22 can be moved outward; if the movable rod 22 is to be moved inward, it is only necessary to remove the lever 43 from the mounting tube 422, rotate it 180 degrees and then install it again into the mounting tube 422. At this time, the clamping portion 422 and the guide surface 433 change positions, and the transmission wheel 41 can be driven to rotate in the clockwise direction by moving the handle 421 back and forth, so that the movable rod 22 can be retreated into the swing arm 20.

[0024] In this embodiment, the movable rod can be driven to move to the target position in the swing arm by moving the handle back and forth up and down, and then the cover plate is clamped between the first angle steel and the second angle steel by swinging the frame. The lever principle is used to make the movement of the cover plate more labor-saving, thereby improving the convenience of disassembly and assembly of the cover plate.

[0025] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
