Description

Technical Field

[0001] This utility model relates to the field of coke oven equipment application technology, specifically to a tool for disassembling and assembling a coke oven gas exchange valve top screw spring. Background Technology

[0002] When using a conventional box wrench to disassemble and assemble the set screw spring of the coke oven gas exchange valve, it is necessary to repeatedly take the wrench out and put it back in, and two people are required to work together to remove the set screw spring, which makes the work efficiency low. At the same time, since there are a lot of coke oven gas exchange valves, usually around 130 per coke oven, the disassembly and assembly takes a lot of time. Utility Model Content

[0003] This utility model provides a tool for disassembling and assembling the set screw spring of the coke oven gas exchange valve, in order to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tool for disassembling and assembling a coke oven gas exchange valve set screw spring includes a box wrench, one end of which has a box wrench head, and the other end of which has a rotating steel pipe handle.

[0006] Furthermore, the side of the wrench's star-shaped head is covered with a sealing steel plate.

[0007] Furthermore, a bearing is fixedly connected to the other end of the box wrench, the steel pipe handle is rotatably connected to the bearing, and the end of the steel pipe handle away from the box wrench is also rotatably connected to the bearing.

[0008] Furthermore, a welding shaft is also fixedly provided on the inner side of the steel pipe handle.

[0009] This utility model has the following beneficial effects:

[0010] This utility model provides a tool for disassembling and assembling the set screw spring of a coke oven gas exchange cock. By adding a wrench head matching the set screw spring bolt to one side of a conventional box wrench, and a rotatable steel pipe handle on the other side, the operator, with the limiting and sealing effect of the sealing steel plate on the wrench head, holds the set screw spring with one hand and grasps the welded shaft and steel pipe handle of the exchange cock tightening wrench with the other hand. After fixing the wrench clamp to the end of the set screw spring bolt, rotating the wrench allows for tightening or loosening the exchange cock set screw spring. This effectively improves the efficiency of disassembling and assembling the exchange cock set screw spring, solving the problem that currently, when using a conventional box wrench to disassemble and assemble the coke oven gas exchange cock set screw spring, the lack of dedicated disassembly tools often leads to laborious disassembly and assembly processes, ultimately affecting the overall production efficiency of the coke oven.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-2 As shown, a tool for disassembling and assembling a coke oven gas exchange valve top screw spring includes a box wrench 4, one end of which is provided with a box wrench head 8, and the other end of the box wrench 4 is provided with a steel pipe handle 6.

[0017] The side of the wrench's box head 8 is covered with a sealing steel plate 5.

[0018] The other end of the box wrench 4 is fixedly connected to a bearing 7. The steel pipe handle 6 and the bearing 7 are rotatably connected. The end of the steel pipe handle 6 away from the box wrench 4 is also rotatably connected to a bearing 7.

[0019] A welding shaft 9 is also fixedly installed on the inside of the steel pipe handle 6.

[0020] In use, a conventional box wrench 4, corresponding to the size of the nut 3 of the coke oven gas exchange valve 1 and the set screw spring 2, is cut in half, leaving a handle length of about 5-8cm. Two small bearings 7, each with an inner diameter of about 10-20mm, are installed at both ends of a 10cm long shaft. The outer ring of the bearings 7 is fixed inside a 10cm long steel pipe handle 6. One end of the small bearing 7 shaft is vertically welded to the end of the box wrench 4 handle, creating a new wrench handle. The box wrench 4 is then sealed with the jaws facing the new handle. The steel plate 5 is used to seal the limit. When using it, one hand can hold the new handle and rotate it at high speed to disassemble and install it, while the other hand supports the set screw spring 2 of the exchange valve 1. After fixing the wrench pliers to the end of the nut 3 of the set screw spring 2, the wrench is rotated to tighten or loosen it. This effectively improves the efficiency of disassembling and installing the coke oven gas exchange valve 1. It solves the problem that in the process of cleaning and replacing the coke oven gas exchange valve, the conventional use of a wrench is not only inefficient in tightening and loosening, but also requires two people to cooperate, which is time-consuming and laborious when removing the set screw spring 2. Therefore, this tool has good practicality.
