Description

Technical Field

[0001] The utility model relates to a disassembly auxiliary tool, in particular to a tool for conveniently and quickly disassembling a pin shaft and a bearing. Background Art

[0002] In various production processes, most valve equipment uses hydraulic cylinders to realize the opening and closing of valves. The connection between the hydraulic cylinder and the equipment is fixed by pins. For example, various valves (blind valves, glasses valves, etc.) cannot be disassembled normally after the connection pins are deformed due to frequent opening and closing. For example, the bearings of various reducer motors are also inconvenient to disassemble due to deformation and damage. When replacing online, it is impossible to use large tools to knock and dismantle due to the narrow construction space. During maintenance, it is impossible to disassemble quickly, affecting the maintenance progress and time. In case of emergency, destructive dismantling is required for replacement, which is time-consuming, labor-intensive, and wastes resources. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a tool for conveniently and quickly disassembling a pin shaft and a bearing, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the technical solutions adopted are as follows:

[0005] A convenient and quick tool for disassembling a pin shaft and a bearing, comprising a steel chisel, a baffle plate 1 is fixedly connected to the upper end of the steel chisel, a threaded joint is fixedly arranged at the other end of the steel chisel, a baffle plate 2 is fixedly installed on the steel chisel, a sliding hammer is slidably penetrated on the steel chisel, and the sliding hammer is arranged between the baffle plate 1 and the baffle plate 2;

[0006] A rope ring is fixedly connected to the upper portion of the baffle, and pull ropes are respectively connected to both sides of the slide hammer.

[0007] As a further improvement of the utility model, cards are symmetrically installed on both sides of the steel drill and close to the threaded joint, and the cards can be rotatably installed on the steel drill through hinges.

[0008] As a further improvement of the utility model, rubber gaskets are attached to the end surfaces on both sides of the slide hammer.

[0009] The beneficial effects of the utility model are:

[0010] The tool has a simple structure and low manufacturing cost. It can avoid the situation where destructive demolition by gas cutting is required due to the inability to dismantle. It can shorten the dismantling in a narrow space where large tools cannot be used due to pin deformation or bearing damage, thereby improving the dismantling efficiency. The length can be adjusted according to the size of the space. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The drawings constituting a part of this application are used to provide a further understanding of the present invention. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
