Description

Technical Field

[0001] The utility model belongs to the technical field of manhole cover disassembly and assembly tools, in particular to a manhole cover manual disassembly and assembly tool. Background Art

[0002] In modern urban construction, in order to reduce the layout of pipelines on the ground, cables and pipelines such as electricity, communications, water and natural gas are usually laid in underground passages. These passages will have an exit to the ground at intervals. The section from the passage to the exit is called a manhole. In order to improve the safety of pedestrians and vehicles, manhole covers are usually installed on the top of the manhole. Manhole covers are usually made of reinforced cement, metal, reinforced plastic and other materials, and are round or square in shape. In order to facilitate the disassembly and assembly of the manhole cover, at least two symmetrical through holes are set on the manhole cover. When disassembling and assembling the manhole cover, the tool is connected to the hole to achieve connection with the manhole cover, so as to facilitate the installation and removal of the manhole cover.

[0003] At present, when installing and removing the manhole cover, construction workers usually need two people to cooperate. They each use a hook to insert into the through hole on the manhole cover, and then directly disassemble and install the manhole cover by manpower. This method of installing and removing the manhole cover is more laborious, and the construction workers are close to the manhole cover. Once the manhole cover slips, it is easy to injure the construction workers. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a manual manhole cover disassembly and assembly tool, which has a simple structure and can save physical strength when disassembling and assembling the manhole cover. It can be operated by one person and can effectively improve the safety when disassembling and assembling the manhole cover.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0007] A supporting leg parallel to each other is vertically arranged at each end of the crossbar, and the ends of the two supporting legs face the same direction, and the distance between the ends of the supporting legs and the crossbar is the same;

[0008] The vertical rod is vertically arranged at the midpoint of the horizontal rod, and the vertical rod is perpendicular to the supporting legs;

[0009] The support rod is rotatably arranged at the end of the vertical rod. When the direction of the support rod is consistent with the direction of the legs, the support rod and the two legs jointly support the vertical rod and the horizontal rod at intervals on the ground.

[0010] Two slings are provided, one end of which is connected to the vertical rod, and the connection point is located in the middle of the vertical rod. The other ends of the slings are provided with hooks.

[0011] The beneficial effect of the utility model is that: using the manhole cover disassembly and assembly tool of this scheme, only one person is needed to disassemble and assemble the manhole cover, and during the disassembly and assembly process, the operator can stay away from the manhole cover to avoid being injured, and the use of the lever principle can save physical strength, and the overall structure of the tool is simple, which is easy to transfer and use.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0017] like Figure 1 , Figure 2 As shown, a manual disassembly and assembly tool for a manhole cover comprises: a horizontal bar 1, a vertical bar 2, a support bar 3 and a sling 4.

[0018] Two legs 11 parallel to each other are vertically disposed at both ends of the crossbar 1 , and the ends of the two legs 11 face the same direction, and the distance between the ends of the legs 11 and the crossbar 1 is the same.

[0019] The vertical rod 2 is vertically arranged at the midpoint of the horizontal rod 1 , and the vertical rod 2 is perpendicular to the supporting leg 11 .

[0020] The support rod 3 is rotatably arranged at the end of the vertical rod 2. Specifically, the support rod 3 can be swung toward both sides of the vertical rod 2, and can also be swung toward the end of the vertical rod 2. When the direction of the support rod 3 is consistent with the direction of the support legs 11, the support rod 3 and the two support legs 11 jointly support the vertical rod 2 and the horizontal rod 1 on the ground at intervals.

[0021] Two slings 4 are provided, one end of which is connected to the vertical rod 2 , and the connection is located in the middle of the vertical rod 2 . The other ends of the slings 4 are provided with hooks 41 .

[0022] When removing the manhole cover, the vertical rod 2 is placed across the top of the manhole cover, and the ends of the two legs 11 are used to support the bottom surface, and the support rod 3 is swung so that it does not contact the ground, so as to adjust the height of the vertical rod 2 with the part where the legs 11 contact the ground as the fulcrum, thereby facilitating the connection of the hooks 41 provided on the two slings 4 with the through holes on the manhole cover. After the hooks 41 are connected to the manhole cover, the construction workers only need one person to lift the end of the vertical rod 2 upward to lift the manhole cover upward, thereby achieving the purpose of removing the manhole cover; after the manhole cover is removed, the disassembly and assembly tool is moved to one side of the manhole with the legs 11 as the fulcrum, the manhole cover is removed from the top of the manhole, and then the support rod 3 is swung to the direction consistent with the direction of the legs 11, and the ends of the support rod 3 are used to support the ground, so that it cooperates with the two legs 11 to support the vertical rod 2.

[0023] When installing the manhole cover, use the hook 41 to connect the through hole on the manhole cover, then use the support leg 11 as a fulcrum to lift the end of the vertical rod 2 upward, move the manhole cover to the manhole, and then move the vertical rod 2 downward. During the downward movement, the position of the manhole cover can be fine-tuned by swinging the vertical rod 2 left and right to facilitate placing the manhole cover at the wellhead of the manhole.

[0024] By using the manhole cover disassembly and assembly tool of the present invention, only one person is needed to disassemble and assemble the manhole cover. During the disassembly and assembly process, the operator can stay away from the manhole cover to avoid being injured. The lever principle can save physical strength, and the overall structure of the tool is simple, which is easy to transfer and use.

[0025] Preferably, Figure 1 , Figure 2 As shown, rollers 12 are provided at the ends of the legs 11 to facilitate the overall movement of the tool and to facilitate fine-tuning of the manhole cover position when installing the manhole cover.

[0027] Preferably, the support rod 3 is rotatably disposed at the end of the vertical rod 2, and the rotation axis is parallel to the horizontal rod 1. Figure 1 As shown, when the support rod 3 rotates to the bottom of the vertical rod 2, the direction of the support rod 3 is consistent with the direction of the support leg 11, and the support function is achieved at this time. Figure 2 As shown, when the support rod 3 rotates to the top of the vertical rod 2, the support rod 3 is arranged parallel to the top of the vertical rod 2 to prevent the support rod 3 from affecting the descent of the vertical rod 2.

[0028] Preferably, Figure 1 , Figure 2As shown, a sliding sleeve 5 is slidably provided on the vertical rod 2, and a locking screw 51 is passed through its side wall. A hanging ring 52 is provided at the bottom of the sliding sleeve 5, and the upper ends of the two slings 4 are connected to the hanging ring 52. During use, the position of the sliding sleeve 5 on the vertical rod 2 can be adjusted to facilitate the adjustment of the force position of the vertical rod 2, so as to find a more labor-saving force point under the condition of adapting to the size of the manhole cover, and the sliding sleeve 5 can be fixed with the locking screw 51 after adjustment.

[0029] Further preferably, Figure 1 , Figure 2 As shown, the vertical rod 2 is provided with a plurality of positioning holes 22 along the length direction for passing locking screws 51 to prevent the sliding sleeve 5 from sliding randomly.

[0030] Preferably, both the crossbar 1 and the vertical bar 2 are tube structures to reduce the overall weight of the tool.

[0031] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model.
