[0032] Such as Figures 1-4, a cable manhole cover lifting device, comprising: a moving frame 1, a fixed rod 2, a movable rod 3, a handle 4 and a lifting rope 5;

[0033] A moving wheel 11 is provided at the bottom of the mobile frame 1; one end of the fixed rod 2 is installed on the mobile frame 1, and the other end of the fixed rod 2 is installed with the handle 4; the fixed rod 2 is provided with a telescopic slot 21, and the notch of the telescopic slot 21 is close to the mobile frame 1, and the movable rod 3 is movably installed in the telescopic slot 21, and the movable rod 3 moves to extend out or be stored in the telescopic slot 21; one of the hanging ropes 5 is connected to the movable rod 3 and is located at an end away from the handle 4; the other hanging rope 5 is connected to the fixed rod 2.

[0034] The present invention provides a cable manhole cover lifting device, which fixes one end of a fixed rod 2 on a movable frame 1, and can use a movable wheel 11 under the movable frame 1 as a fulcrum. The cable manhole cover 10 is lifted by the lifting rope 5 of the movable rod 3 according to the lever principle, and the cable manhole cover 10 is driven to move horizontally by the lifting rope 5 of the fixed rod 2. The center of gravity of the cable manhole cover 10 is controllable, which facilitates the lifting of the cable manhole cover 10 and makes the transfer of the cable manhole cover 10 more stable, thereby solving the problem that the lifting and transfer of the existing cable manhole cover 10 cannot be carried out synchronously, resulting in the time-consuming and labor-intensive lifting and lowering of the cable manhole cover 10.

[0035] Specifically, when the cable well cover 10 needs to be transferred, the mobile frame 1 can be moved to the cable well cover 10, and the movable rod 3 can be driven to move relatively to the telescopic slot 21 of the fixed rod 2, so that the mobile frame 1 is extended or retracted in the telescopic slot 21, thereby increasing or decreasing the spacing between the suspension ropes 5 of the fixed rod 2 and the movable rod 3, so that the position of the mobile frame 1 can be adjusted to be close to the middle of the cable well cover 10, and one end of the movable rod 3 is located above the edge of the cable well cover 10, and at the same time, the suspension rope 5 of the movable rod 3 is fixed to the front end (such as a mouth, hole, groove, edge, etc.) of the cable well cover 10 below, and then the handle 4 is driven to swing downward, so that the fixed rod 2 rotates with the moving wheel 11 as the fulcrum, driving the movable rod 3 to rotate. 3 is swung upward until it is tilted, and the movable rod 3 drives one end of the cable well cover 10 to be detached from the installation position through the hanging rope 5; at this time, the hanging rope 5 of the fixed rod 2 can be fixed to the rear end of the cable well cover 10; the handle 4 is driven to swing slightly upward again, so that the hanging rope 5 of the fixed rod 2 moves upward to make the rear end of the cable well cover 10 detach from its original position, and the hanging rope 5 of the movable rod 3 moves downward (but the front end of the cable well cover 10 is still detached from its original position and kept in a suspended state), and the handle 4 is driven to move forward, driving the fixed rod 2 to move forward, and driving the cable well cover 10 to be completely horizontally detached from its original position through the movable rod 3 and its hanging rope 5, so that the lifting and transfer steps of the cable well cover 10 can be carried out seamlessly.

[0036] It can be optimized to further include: a winding wheel 6;

[0037] The reel 6 is rotatably and adjustably connected to the fixing rod 2 , and one of the suspension ropes 5 is reeled on the reel 6 .

[0038] In this solution, the rope 5 is preferably indirectly connected to the fixed rod 2 through the reel 6; one of the ropes 5 is reeled on the reel 6, and when the reel 6 is rotated to adjust, the rope 5 can be driven to reel or unreel, thereby adjusting the height position of the lower end of the rope 5; in this way, the ropes 5 of both the fixed rod 2 and the movable rod 3 can be fixed to the cable manhole cover 10 at the beginning, and the rope 5 of the movable rod 3 is in a tight state when the cable manhole cover 10 is lifted, while the rope 5 of the fixed rod 2 can be in a relaxed state. When one end of the cable manhole cover 10 is lifted, the reel 6 can be driven to rotate, and the reel 6 reels the rope 5 to make the rope 5 of the fixed rod 2 in a tight state, and finally the cable manhole cover 10 is completely detached from its original position. In this way, the cable manhole cover 10 does not need to fix the rope 5 twice during the transfer, which improves the lifting and lowering efficiency of the cable manhole cover 10.

[0039] It can be optimized to further include: a position adjustment seat 7;

[0040] The position adjustment seat 7 is installed on the fixing rod 2 in an adjustable manner; the winding wheel 6 is installed on the position adjustment seat 7 in a rotationally adjustable manner.

[0041] The reel 6 of the present solution can be directly fixed to the fixed rod 2 as needed, or can be installed on the position adjustment seat 7, and indirectly installed on the fixed rod 2 through the position adjustment seat 7; the position of the suspension rope 5 of the fixed rod 2 can be adjusted, and the suspension rope 5 can be installed at a position close to or far away from the suspension rope 5 in the movable rod 3, so that a smaller or larger cable manhole cover 10 can be lifted, and based on the telescopic adjustment of the movable rod 3, the cable manhole cover 10 can keep its center of gravity near the mobile frame 1. The position adjustment seat 7 can be fixed to the fixed rod 2 in a known manner, such as screw fixing, clamp fixing, buckle fixing, etc., as long as the position adjustment seat 7 is limited to other areas of the fixed rod 2 after being disassembled or moved.

[0042] Optimally, a plurality of fixing columns 22 are provided on the outer side of the fixing rod 2 along the length direction; a fixing station 23 is formed between two adjacent fixing columns 22;

[0043] The position adjustment seat 7 is provided with a seat groove 71, and a rotating plate 72 is provided on the outer side of the seat groove 71; the rotating plate 72 is provided with a rotating hole 73; the rotating hole 73 is detachably clamped to the fixed column 22, and the position adjustment seat 7 is rotated around the rotating hole 73 until the seat groove 71 is clamped to the fixed station 23.

[0044] The position adjusting seat 7 can be limited to different fixing stations 23 of the fixing rod 2 as needed; specifically, the position adjusting seat 7 is provided with a rotating plate 72, and the rotating plate 72 is clamped to the fixing column 22 through a rotating hole 73. The rotating plate 72 rotates around its own rotating hole 73 to clamp the seat groove 71 to different fixing stations 23 of the fixing rod 2, that is, a part of the fixing rod 2 is located in the seat groove 71, so that the winding wheel 6 is limited to different positions of the fixing rod 2. At the same time, the winding wheel 6 can be installed at any position of the position adjusting seat 7 as needed, such as the outer side wall of the seat groove 71, etc.

[0045] Optimally, it further includes: a tray 8; the lower end of the lifting rope 5 is connected to the middle of the tray 8.

[0046] The lifting rope 5 of this solution can be directly tied to the cable manhole cover 10 at the lower end, or indirectly connected to the cable manhole cover 10 in any structure; for the cable manhole cover 10 with a grid opening, it is preferable to use the tray 8 to connect the cable manhole cover 10. Only need to design the thickness of the tray 8 to be less than the inner diameter of the grid opening and the outer diameter of the tray 8 to be greater than the inner diameter of the grid opening. In this way, after the tray 8 vertically extends into the grid opening, then make the tray 8 horizontally face upward to abut against the bottom of the grid opening, so as to lift the cable manhole cover 10 upward. In this way, the connection and disassembly of the lifting rope 5 to the cable manhole cover 10 are more convenient.

[0047] Optimally, the moving frame 1 is provided with a T-shaped block 12, and the movable rod 3 is provided with a T-shaped groove 31 along the length direction, and the T-shaped block 12 is limited to move in the T-shaped groove 31.

[0048] The outer side of the movable rod 3 of this solution can be clamped in the telescopic groove 21 of the fixing rod 2, and the T-shaped groove 31 of the movable rod 3 can also be clamped to the T-shaped block 12 of the moving frame 1 relatively movably; in this way, the movable rod 3 is simultaneously limited by the telescopic groove 21 and the T-shaped groove 31. When the extended section of the movable rod 3 is long, it will not sink, which can make the telescopic movement of the movable rod 3 more stable and also improve the support stability of the movable rod 3.

[0049] Optimally, it further includes: a locking member 9;

[0050] The side wall of the telescopic groove 21 is provided with a hollow fixed bayonet 24; the outer side of the movable rod 3 is provided with a plurality of movable bayonets 32 along the length direction; the locking member 9 can be detachably inserted into the fixed bayonet 24 and one of the movable bayonets 32 to limit the movable rod 3 in the telescopic groove 21.

[0051] The locking member 9 can be inserted into the telescopic groove 21 from the outside to the inside and inserted into one of the movable bayonets 32, so that the movable rod 3 can be limited in the telescopic groove 21, thereby fixing the position between the movable rod 3 and the fixed rod 2, and further fixing the distance between the suspension ropes 5 of the movable rod 3 and the fixed rod 2; thus, in this solution, the locking member 9 can be quickly installed on the fixed rod 2, and it can be quickly switched to lift cable manhole covers 10 of different sizes.

[0052] Optimally, the moving frame 1 includes: a support rod 13, a cross bar 14 and the moving wheels 11;

[0053] The support rods 13 are arranged in pairs. The upper ends of the support rods 13 are connected to the fixed rod 2, and the lower ends of the support rods 13 are connected to the moving wheels 11. The distance between the two support rods 13 gradually increases from top to bottom; the cross bar 14 is horizontally arranged between the upper and lower ends of the support rods 13. One end of the cross bar 14 is connected to one of the support rods 13, and the other end of the cross bar 14 is connected to the other support rod 13.

[0054] The distance between the two support rods 13 gradually increases from the upper end to the lower end. When the cross bar 14 is horizontally arranged between the upper and lower ends of the support rods 13, the cross bar 14 forms a triangular structure between the two support rods 13, which can provide the most stable structure, thereby improving the support stability of the moving frame 1. At the same time, the distance between the support rods 13 is the largest at the lower part, which can accommodate cable manhole covers of larger sizes.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
