Description

Technical Field

[0001] The present application relates to the technical field of municipal manhole cover opening tools, and in particular to a portable tool for opening municipal manhole covers. Background Art

[0002] At present, municipal manhole covers in cities are the most obvious equipment in the entire drainage system in the public eye. They are widely used in large numbers. Most of them are set up outdoors for a long time. The maintenance of the drainage network requires operators to open the municipal manhole covers to enter the network. Due to the long-term use of municipal manhole covers, they are rusted, clogged with sand and gravel, and deformed under long-term pressure. Some municipal manhole covers are difficult to open.

[0003] In the related art, municipal manhole covers are opened mainly by operators using tools such as crowbars to hook the opening hole of the manhole cover and pull it up with force. However, due to the rust, sand and gravel blockage, long-term compression and deformation caused by long-term use of municipal manhole covers, the current opening method is not completely effective. In addition, since it is purely manual pulling, it requires high strength and skills from the operators. If they are not careful, improper force may cause the crowbar to slip out of their hands, or the crowbar may accidentally separate from the opening hole. In severe cases, the heavy manhole cover may lose control and hit the operators. Utility Model Content

[0004] The purpose of the present application is to provide a portable tool for opening municipal manhole covers, so as to solve the problem that the current method of opening the cover is not completely effective, and because it is purely manual pulling, it requires high strength and skills from the operators. Inadvertently, improper force may occur, causing the crowbar to slip out of the hand, or the crowbar may accidentally separate from the opening hole. In serious cases, the heavy manhole cover may lose control and hit the operator.

[0007] Furthermore, the connecting tooling includes a clamping block clamped with the manhole cover, a connecting column is arranged on the top of the clamping block, and a handle cooperating with the lever tooling is arranged on the top of the connecting column.

[0008] Furthermore, the manhole cover is provided with a cover opening hole which is engaged with the clamping block.

[0009] Furthermore, the lever tooling includes a force rod matched with the fulcrum tooling, and one end of the force rod is provided with a lifting hook matched with the handle.

[0010] Furthermore, the fulcrum tooling includes a base placed on the ground, an inverted Y-shaped fulcrum is arranged on the top of the base, and one side of the force rod cooperates with the top of the inverted Y-shaped fulcrum.

[0016] The following is combined with Figure 1 This application is described in further detail.

[0017] The present application embodiment discloses a portable tool for opening a municipal manhole cover, referring to Figure 1 In this embodiment, the portable tooling includes a connecting tooling 1, a lever tooling 2 and a fulcrum tooling 3. Among them, one end of the connecting tooling 1 cooperates with the manhole cover 4; the fulcrum tooling 3 is placed on the ground; one end of the lever tooling 2 cooperates with the connecting tooling 1, and the other end of the lever tooling 2 cooperates with the fulcrum tooling 3. The lever tooling 2 is supported by the fulcrum tooling 3, and the lever tooling 2 cooperates with the connecting tooling 1 to lift it, so that the connecting tooling 1 opens the manhole cover 4.

[0018] Therefore, by setting up a structure that combines the connecting tool 1, the lever tool 2 and the fulcrum tool 3, it is possible to achieve efficient opening of the municipal manhole cover 4 in a complex working environment. At the same time, the lever principle is used to generate concentrated and effective opening force to overcome the difficulties in opening the cover caused by rust, sand and gravel blockage, long-term compression deformation, etc.; in addition, it can also reduce the problem of the manhole cover 4 hitting the operating personnel due to loss of control at a high position.

[0019] The structures of the connecting fixture 1, the lever fixture 2 and the fulcrum fixture 3 are described in detail below:

[0020] Specifically, refer to Figure 1 In this embodiment, the connecting tool 1 includes a block 11, a connecting column 12 and a handle 13. The block 11 is in a rectangular structure, and a cover opening hole 41 is provided on the manhole cover 4. The cover opening hole 41 is in a rectangular structure, and the block 11 cooperates with the cover opening hole 41; when the block 11 and the cover opening hole 41 are placed parallel to each other, the block 11 can be inserted into the cover opening hole 41.

[0021] One end of the connecting column 12 is fixedly mounted on the top of the clamping block 11; the handle 13 is rotatably connected to the end of the connecting column 12 away from the clamping block 11, and the handle 13 is annular in structure, and the handle 13 cooperates with the lever fixture 2. At the same time, the diameter of the handle 13 is greater than the length of the cover opening hole 41, so that the clamping block 11 and the connecting column 12 extend into the cover opening hole 41, and the handle 13 is clamped on the top of the manhole cover 4, so that the connecting fixture 1 can be placed on the manhole cover 4.

[0022] When the clamping block 11 is inserted into the cover opening 41, the handle 13 is then rotated, the handle 13 drives the connecting column 12 to rotate, and the connecting column 12 drives the clamping block 11 to rotate, so that the clamping block 11 and the cover opening 41 are perpendicular to each other, so that the clamping block 11 is clamped in the manhole cover 4, and then the entire connecting tooling 1 is clamped on the manhole cover 4.

[0023] In addition, specifically, refer to Figure 1 In this embodiment, the lever fixture 2 includes a force rod 21 and a lifting hook 22. The force rod 21 is a rectangular strip structure, and one side of the force rod 21 cooperates with the fulcrum fixture 3, so that the force rod 21 is supported by the fulcrum fixture 3; one end of the lifting hook 22 is installed on one end of the force rod 21, and the end of the lifting hook 22 away from the force rod 21 cooperates with the handle 13, so that the hook end of the lifting hook 22 extends into the handle 13 to effectively hook the handle 13.

[0024] In addition, specifically, refer to Figure 1In this embodiment, the fulcrum tooling 3 includes a base 31 and an inverted Y-shaped fulcrum 32. The base 31 is placed on the ground; the inverted Y-shaped fulcrum 32 is installed on the top of the base 31, and a limiting groove is provided on one side of the force rod 21. The limiting groove and the top of the inverted Y-shaped fulcrum 32 are movably matched with each other, so that the inverted Y-shaped fulcrum 32 effectively supports one side of the force rod 21 through the limiting groove, so that the inverted Y-shaped fulcrum 32 and the force rod 21 can be stably contacted during the force generation process.

[0025] Preferably, in the present embodiment, an anti-skid pad is installed at the bottom of the base 31. The anti-skid pad can effectively prevent skidding, so that the base 31 can be placed on the ground more stably during operation.

[0026] The implementation principle of a portable tool for opening a municipal manhole cover in an embodiment of the present application is as follows: after the connecting tool 1 is connected to the opening hole 41 of the municipal manhole cover 4, the force rod 21 is placed on the top of the inverted Y-shaped fulcrum 32 through the limiting groove, and then the lifting hook 22 and the handle 13 are connected and hooked to each other, and then the operator only needs to step on the end of the force rod 21 away from the lifting hook 22, and the municipal manhole cover 4 can be lifted by using the lever principle, thereby completing the process of opening the municipal manhole cover 4.

[0027] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
