Technical Field
The utility model relates to the technical field of manual hardware tools, in particular to a mining U-shaped pin mounting and dismounting tool which is convenient to carry, has dual purposes of mounting and dismounting and can be used for underground narrow spaces.
Background
The U-shaped pins are largely used in fixing the bracket and the pipeline of the underground high-mining or fully-mechanized caving face of the coal mine, when the U-shaped pins are used for fixing, the U-shaped pins are very convenient to insert, and the U-shaped pins can be fixed in place by lightly knocking with a tool after the U-shaped pins are inserted. When the pipe is disassembled, the pipe parts are corroded and adhered to the U-shaped pin due to the reasons of moist underground environment and the like; meanwhile, the U-shaped pin is difficult to disassemble and take in the disassembling and recycling process of the equipment due to the long recovery time of the working face, the long-time stress deformation of the U-shaped pin and the like. When equipment maintenance or pipeline replacement needs to be carried out, the U-shaped pin cannot be detached at one time due to the fact that the mining U-shaped pin is deeply inserted, tools such as a pneumatic pick tip, a sledge hammer, a crowbar and a sling chain are used for working in a matched mode to enable the U-shaped pin to be separated from an iron pipe of a hydraulic support, and the method is not only complex in tool using and operation procedures, but also high in personnel investment and low in operation efficiency, and severely restricts improvement of the whole operation efficiency.
Disclosure of Invention
The utility model aims to overcome the defects of the technology and provides a mining U-shaped pin mounting and dismounting tool which has a hammer head function, is suitable for a narrow space, can be matched with a quick dismounting tool, is convenient to carry, and is safe and practical.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a mining U-shaped pin mounting and dismounting tool comprises a holding handle, an arc-shaped prying head and a right-angle prying head, and is characterized in that one end of the head of the arc-shaped prying head is provided with a small hammer head surface, a small arc supporting surface and a small arc working surface, the small hammer head surface is used as a hammer function or a knocking surface, and the small arc supporting surface and the small arc working surface form a smaller arc which can be used as a prying bar to pull out a small stroke gap; the head end of the right-angle prying head is provided with a large hammerhead face, a large arc supporting face and a large arc working face, the large hammerhead face is used as a hammer function or a knocking face, and the large arc supporting face and the large arc working face form a large arc shape and can be used as a pry bar to extract a large stroke gap.
A mining U-shaped pin mounting and dismounting tool is characterized in that an arc-shaped lever head is further provided with a side face a and a side face b, and the included angle between the side face a and the side face b of the arc-shaped lever head is 5-10 degrees, so that a narrow gap can be inserted.
The utility model provides a mining U type round pin installation demolishs operation instrument, right angle sled bar head still is equipped with side c and side d, right angle sled bar head side c and side d contained angle 6-15 degrees can insert narrow and small clearance.
The mine U-shaped pin hammer is reasonable in design, simple in structure, easy to manufacture, time-saving and labor-saving, the head characteristics of the arc-shaped pry head and the right-angle pry head can be easily inserted into the mine U-shaped pin, the two pry heads are matched to easily take out the mine U-shaped pin, the mine U-shaped pin hammer is convenient to use, has a hammer head function, can be used for mounting the mine U-shaped pin in a knocking mode, is convenient to carry, is high in working efficiency, and is suitable for underground spacious work operation.
