Description

Novel dismantling pliers

Technical Field

The utility model belongs to the technical field of the coal mine production, concretely relates to novel dismantlement pincers that attach fitting department carries out dismantlement when extracting for colliery coal seam gas in the pit.

Background

In recent years, with the continuous development of coal mine extraction technology, high gas mines are continuously generated in the drilling and mining process, in order to reasonably and effectively smelt gas, a drilling and mining process of first pumping and then mining is adopted to extract gas in the mines, when gas is extracted, in order to prevent gas leakage, a connecting joint is adopted at a pipe joint to connect an upper section of pipe and a lower section of pipe, the connecting joint and the pipe joint adopt a socket joint mode, in order to ensure the sealing requirement of the connecting joint,

scribble sealed glue at the kneck, simultaneously, because of colliery manufacturing enterprise reduce cost's requirement, after the gas extraction, carry out secondary recycle to the great tubular product of use amount and attach fitting, nevertheless can meet following several main problems at the dismantlement in-process: firstly, the pipe fittings and joints are made of polyethylene materials mostly, sealant is also coated at the joints, the clamping force of common pipe tongs is large and cannot be accurately controlled, and simultaneously, the tong teeth at the occlusion parts of the common pipe tongs are in contact with the polyethylene materials of the pipe fittings due to high material strength of the tong teeth, so that the phenomenon that stress concentration easily occurs at the pipe fittings and the connection joints, and occlusion cracks are easily caused, and the special connection joints and the pipe fittings are easily damaged; secondly, because of the restriction of the site construction conditions of the mine, the standardized hole connecting device adopted during gas extraction mostly adopts a plurality of pipelines in the same direction to be arranged in parallel and uniformly, the distance between the pipelines is small, when the valve and the butt joint are replaced and disassembled on the pipelines, the space position is too small, the jaw part of the common pipe wrench cannot enter, the effect of the pipe wrench engaging the pipe fitting or the connecting joint cannot be realized, and the existing tools cannot be adopted to disassemble the pipe fitting, the connecting joint and other parts.

Therefore, a set of novel disassembly pliers which are suitable for the use requirement of the pipe, time-saving and labor-saving, do not cause the damage of other pipe fittings and are easy to operate needs to be designed.

Disclosure of Invention

In view of the above problem, the utility model aims at providing a novel dismantlement pincers, to the damage of pipe fitting and joint department when having overcome the dismantlement pipe fitting, satisfy under the narrow state of construction condition, novel dismantlement pincers can wrap up the pipe fitting completely and connect, satisfy the dismantlement requirement, and simple structure, convenient operation, low in cost improves work efficiency.

In order to achieve the above purpose, the utility model provides a technical scheme is: the main handle clamping part is provided with a pair of tongs, a rubber sheet is fixedly adhered to the tongs, one end of the main handle is provided with a fixed column, the middle part of the main handle is provided with a connecting hole, the middle part of the auxiliary handle is provided with a continuous adjusting hole, the connecting hole of the main handle is connected with the adjusting hole of the auxiliary handle through a bolt, one end of the auxiliary handle is connected with the closing block through a pin shaft, the other end of the closing block is provided with a fixing bandage, and the fixing bandage is evenly provided with a through hole matched with the fixed column.

Preferably, the inner side of the closing block is provided with an angled polygon.

Preferably, more than three adjustment holes are provided.

Preferably, more than two groups of pliers teeth are arranged at the clamping part of the main handle.

The utility model has the advantages that: the damage to the pipe fitting and the joint when the pipe fitting is disassembled is overcome, the novel disassembling clamp can completely cover the pipe fitting and the joint under the condition that the construction condition is narrow, the disassembling requirement is met, the structure is simple, the operation is convenient, the manufacturing cost is low, and the working efficiency is improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, a clamp tooth 10 is arranged at a clamping position of a main handle 1, a rubber 7 is fixedly adhered to the clamp tooth 10, a fixing column 8 is arranged at one end of the main handle 1, a connecting hole 5 is arranged in the middle of the main handle, a continuous adjusting hole 11 is arranged in the middle of an auxiliary handle 2, the connecting hole 5 of the main handle 1 is connected with the adjusting hole 11 of the auxiliary handle 2 through a bolt 4, one end of the auxiliary handle 2 is connected with a closing block 3 through a pin shaft 6, a fixing bandage 9 is arranged at the other end of the closing block 3, and through holes matched with the fixing column 8 are uniformly arranged on the fixing bandage 9.

The novel disassembly pliers are formed by connecting a main handle 1, an auxiliary handle 2 and a closing block 3 through a bolt 4 through an adjusting hole 11, the handles are of an inner arc structure, an operator can hold the novel disassembly pliers with one hand more conveniently, ergonomic design requirements are met, the main handle 1 and the auxiliary handle 2 select proper positions on the adjusting hole 11 according to the actual size of a disassembly pipe fitting at the adjusting hole 11, the novel disassembly pliers are fixed through the bolt 4, the clamping part of the auxiliary handle 2 is designed to be circular arc, the main handle 1 is uniformly provided with pliers teeth 10 at the circular arc clamping part, flat grooves are arranged between the pliers teeth 10 for connection, the design mode effectively increases the contact area between the pliers teeth 10 and a standard connecting pipe, ensures the contact strength between the pliers teeth 10 and the standard connecting pipe, meets the requirement that the pliers teeth 10 drive the standard connecting pipe to rotate in actual use, and a rubber 7 is adhered to the contact surface of the pliers teeth 10, through this kind of design, guarantee that novel dismantlement pincers are the flexonics with the pipe fitting centre gripping position of polyethylene material, prevent too big because of novel dismantlement pincers hard, can cause the damage of 10 centre gripping position pipe fittings crackles of pincers tooth or other forms, one side of auxiliary handle 2 is connected with closing piece 3 through round pin axle 6, closing piece 3 accessible round pin axle 6 carries out the rotation of certain angle, the centre gripping position of closing piece 3 designs into the polygon that has certain angle, make novel dismantlement pincers when rotating the pipe fitting, can cooperate the better centre gripping pipe fitting of stiff end pincers tooth 10, satisfy the requirement to pipe fitting centre gripping location, the dropout phenomenon prevents to appear, closing piece 3's opposite side is equipped with fixing bandage 9, penetrate fixing column 8 in fixing bandage 9's the location through-hole, fix by the centre gripping pipe fitting, satisfy the in-service use requirement.
