The U-shaped clamp disassembling device is simple in structure, light in weight, easy to carry, convenient for workers to apply force, capable of effectively reducing the labor intensity of the workers and capable of effectively meeting the requirement for disassembling U-shaped clamps in different directions in an underground coal mine.

Description

Technical Field

[0001] The utility model relates to the field of on-site tooling for coal mine production, in particular to a portable U-shaped card extractor. Background Art

[0002] Hydraulic equipment used underground in coal mines requires U-shaped clamps to fix the infusion pipelines. When the pipelines need to be replaced or the U-shaped clamps are rusted, the U-shaped clamps need to be frequently removed. There are no suitable tools to remove the U-shaped clamps. In addition, the space underground in coal mines is small, the operation is unsafe, and it is inconvenient for workers to apply force, resulting in low work efficiency and affecting production.

[0003] The portable U-shaped card extractor is a tool for quickly disassembling the U-shaped card. Due to the different spatial positions of the U-shaped card in coal mines, the portable U-shaped card extractor is required to disassemble the U-shaped card in both horizontal and vertical positions. Utility Model Content

[0004] The purpose of this utility model patent is to provide a portable U-shaped card extractor, which can solve the needs of disassembling horizontal and vertical U-shaped cards.

[0005] The purpose of this utility model patent is achieved through the following technical solutions:

[0006] The appearance of this structure is long and strip-shaped, and includes a straight hook portion, a connecting portion and a superior arc portion. A small semicircular groove is opened on the inner side of the straight hook portion, and there is a raised cylindrical platform on the top of the outer side, and it is in the shape of a pancake near the connecting portion; the superior arc portion gradually thickens from the outside to the inside, and is in the shape of an arc-shaped flat tip, and a small semicircular groove is opened on the inner side, and it is in the shape of a pancake near the connecting portion and has a raised cylindrical platform on the outer side.

[0007] The size of the semicircular small groove inside the straight hook part matches the U-shaped card. When in use, the straight hook part is inserted into the U-shaped card, and the semicircular small groove fits with the U-shaped card, so that the two are not easy to slide relative to each other. The raised cylindrical platform of the straight hook part is used as a fulcrum, and the round cake-shaped knocking point of the superior arc part is hit with a hammer, so that the U-shaped card installed horizontally can be removed. Similarly, when the longitudinal U-shaped card needs to be removed, the longitudinal extraction end of the superior arc part is inserted into the U-shaped card, the semicircular small groove fits with the U-shaped card, the raised cylindrical platform of the superior arc part is used as a fulcrum, and the round cake-shaped knocking point of the straight hook part is hit with a hammer, so that the U-shaped card installed vertically can be removed. The purpose of being able to remove the U-shaped card in the horizontal and vertical directions is achieved. Beneficial Effects

[0008] Before the portable U-shaped card extractor was invented, there was no suitable tool to remove the U-shaped card, and the space in the coal mine was small and it was inconvenient for workers to apply force, which was inefficient and had safety hazards. The utility model has a simple and practical structure, low manufacturing cost, convenient force application, high disassembly efficiency, and also improves the safety of disassembling the U-shaped card.

[0009] The following is a complete and clear description of the technical solution implemented by the utility model in conjunction with the accompanying drawings: BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model;

[0011] Figure 2 This is a schematic diagram of disassembling the horizontal U-shaped card;

[0012] Figure 3 This is a schematic diagram of disassembling the longitudinal U-shaped card;

[0013] Among them: 1. Straight hook part; 2. Connecting part; 3. Superior arc part. DETAILED DESCRIPTION

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, a raised cylindrical platform is provided on the top of the outer side of the straight hook portion 1, and a semicircular small groove is provided on the inner side, and the size of the semicircular small groove matches the U-shaped card. When removing the horizontal U-shaped card, the straight hook portion 1 is inserted into the U-shaped card, and the U-shaped card is embedded in the semicircular small groove, so that the two are not easy to slide relative to each other. The raised cylindrical platform of the straight hook portion is used as a fulcrum, and the round pancake-shaped striking point of the superior arc portion 3 is struck with a hammer, and the U-shaped card is pried up using the lever principle; similarly, Figure 3 As shown, when removing the longitudinal U-shaped card, the superior arc portion 3 is inserted into the U-shaped card, and the U-shaped card is embedded in the semicircular small groove, so that the two are not easy to slide relative to each other. The cylindrical platform of the superior arc portion 3 is used as a fulcrum, and the round pancake-shaped knocking point of the straight hook portion 1 is knocked with a hammer head, and the U-shaped card is pried up using the lever principle, so that the longitudinally installed U-shaped card can be removed. Thus, the purpose of being able to remove the U-shaped card in the horizontal and vertical directions is achieved.
