[0038] In this embodiment, a manhole cover moving device is disclosed. Figure 1 The entire three-dimensional structure of the manhole cover moving device from a first viewing angle is shown; Figure 2 The entire three-dimensional structure of the manhole cover moving device from a second viewing angle is shown; Figure 3 The partial three-dimensional structure of the manhole cover moving device is shown; Figure 4 Shows Figure 3 The three-dimensional structure of the middle A part; Figure 5 Shows Figure 3 The three-dimensional structure of the middle B section; Figure 6 Shows Figure 3 The three-dimensional structure of the middle C part.

[0039] Please refer to Figures 1 to 6 The manhole cover moving device of the utility model includes: a bracket 1, a rotating wheel 2 arranged at the end of the bracket 1, two lifting components 5 symmetrically arranged at the lower end of the bracket 1, and a contact hook 3 arranged at the lower end of the lifting component 5, wherein the bracket 1 is used to support the contact hook 3; the rotating wheel 2 is used to drive the bracket 1 to move; the lifting component 5 is used to drive the contact hook 3 to move up and down; the contact hook 3 is used to hook the manhole cover.

[0040] Secondly, the lifting assembly 5 includes: a connecting column 51, a first threaded rod 53 passing through the connecting column 51, an anti-dropping block 52 arranged on the inner wall of the connecting column 51, a stopper 54 arranged at the upper end of the first threaded rod 53 and abutting on the anti-dropping block 52, and a nut 55 rotatably arranged at the lower end of the connecting column 51; wherein the upper end of the connecting column 51 is fixed to the lower side of the bracket 1, the interior of the connecting column 51 is hollow, and the upper end of the threaded rod is passed through the connecting column 51; the stopper 54 is used to prevent the first threaded rod 53 from falling off; and the nut 55 is used to control the position of the first threaded rod 53. When the first threaded rod 53 descends, when the stopper 54 abuts on the anti-dropping block 52, the first threaded rod 53 no longer moves downward, that is, reaches the lowest position of the contact hook 3 descending, and the nut 55 is threadedly connected to the first threaded rod 53. By setting the nut 55, the first threaded rod 53 can be moved, which reduces the situation that the first threaded rod 53 is difficult to move when the device is in use.

[0041] Secondly, a limiting groove 56 is provided at the lower end of the connecting column 51, and a limiting rod 57 is provided in the limiting groove 56, wherein the lower end of the limiting rod 57 is fixedly provided on the upper side of the nut 55, that is, the upper end of the limiting rod 57 is limited in the limiting groove 56, and the lower end is fixedly connected to the nut 55, and the rotation of the nut 55 drives the limiting rod 57 to rotate in the limiting groove 56. The limiting groove 56 and the limiting rod 57 can realize the rotation connection between the nut 55 and the connecting column 51, realize the movement of the first threaded rod 53 by the nut 55, and realize the control of the upper and lower positions of the contact hook 3.

[0042] Secondly, a connecting block 58 is provided at the lower end of the first threaded rod 53, and the connecting block 58 is used to connect the first threaded rod 53 with the contact hook 3. The connecting block 58 is more convenient to assemble the contact hook 3 with the lifting assembly 5 during installation, and the lifting assembly 5 drives the contact hook 3 to move up and down, and when the contact hook 3 is damaged, it only needs to be separated from the connecting block 58 for replacement, which is more convenient and simple.

[0043] When using the device, the user moves the device to the upper surface of the manhole cover, then combines the contact hook 3 with the inside of the manhole cover, and then rotates the nut 55 to drive the first threaded rod 53 to move the manhole cover. Specifically, the user rotates the nut 55, and then the nut 55 rotates to drive the first threaded rod 53 to move. When the first threaded rod 53 moves, it drives the contact hook 3 to move. By setting the lifting component 5, the contact hook 3 is effectively moved, which reduces the need for the user to use a large number of tools to move the manhole cover when the device is in use, resulting in cumbersome use of the device and low work efficiency, thereby improving the practicability of the device.

[0044] Secondly, an adjustment assembly 6 is provided on the two lifting assemblies 5, and the adjustment assembly 6 is used to adjust the distance between the two lifting assemblies 5. The adjustment assembly 6 includes: two connecting plates, and a second threaded rod 63 arranged between the two connecting plates, wherein the connecting plates include a first connecting plate 61 and a second connecting plate 62, one end of the second threaded rod 63 is rotatably arranged in the middle of the first connecting plate 61, and the other end is passed through the middle of the second connecting plate 62; the two connecting plates are fixedly connected to the connecting columns 51 respectively, and move along the bracket 1. The second threaded rod 63 is rotatably connected to the inner wall of the second connecting plate 62. By setting the second threaded rod 63, the second connecting plate 62 can be moved, which reduces the situation where the second connecting plate 62 is difficult to move when the device is in use.

[0045] Secondly, a limit block 65 is provided at the end of the second threaded rod 63, and the limit block 65 is used to limit the movement distance of the second threaded rod 63. The limit block 65 can control the maximum movement distance of the connecting plate on the second threaded rod 63, and prevent one end of the second threaded rod 63 from being separated from the second connecting plate 62, thereby ensuring the integrity of the device, and preventing the manhole cover from being unable to be moved due to zero-point drop, thereby delaying the construction period.

[0046] Secondly, a threaded rotating block 64 is provided on the second connecting plate 62, and the threaded rotating block 64 is used to drive the second threaded rod 63 to rotate. The threaded rotating block 64 is threadedly connected to the second threaded rod 63. When the device needs to be used, the user rotates the threaded rotating block 64, and then the threaded rotating block 64 rotates to drive the second threaded rod 63 to move, and then the second connecting plate 62 moves to adjust the connecting column 51. By setting the adjustment component 6, the connecting column 51 is effectively adjusted, and the distance between the connecting columns 51 is adjusted, which reduces the difficulty of moving the distance between the connecting columns 51 when the device is in use, resulting in the device being unable to move different types of manhole covers.

[0047] When the device needs to be used, the user rotates the threaded turn block 64, and the threaded turn block 64 rotates to drive the second threaded rod 63 to move, and then the second connecting plate 62 moves to move the connecting column 51. By setting an adjustment device, the connecting column 51 can be effectively adjusted, avoiding the situation where the connecting column 51 cannot move the distance when the device is in use, causing the device to be unable to move manhole covers of different models.

[0048] Secondly, the bracket 1 is an L-shaped bracket; the rotating wheel 2 is arranged at the end of the bracket 1, and the number of the rotating wheels 2 is at least 3. The bracket 1 is L-shaped with a horizontal bar and a vertical bar, and the rotating wheels 2 are arranged at the three ends of the L-shaped bracket respectively. Several rotating wheels 2 are distributed in a triangular shape, which is conducive to the stability of the bracket 1 during operation.

[0049] Secondly, a connecting sleeve 4 is provided on the bracket 1, and the connecting sleeve 4 is used to reinforce the bracket 1. Providing the connecting sleeve 4 at the connection between the crossbar and the vertical bar of the bracket 1 can reinforce the connection between the crossbar and the vertical bar, avoid separation of the crossbar and the vertical bar, ensure the stability of the bracket 1, and enhance the practicality of the device.
