Description

Technical Field

[0001] The utility model belongs to the technical field of gas emergency repair equipment, and particularly relates to a rapid emergency repair auxiliary tool for a gas relief valve. Background Technique

[0002] In urban public works, as one of the public works maintaining the normal operation of the city, gas pipelines are usually buried due to the flammable and explosive nature of the medium. Therefore, relevant valves are also buried underground. On both sides of the pipeline valve, relief valves are usually provided for gas relief in case of emergency. Due to urban construction changes, the buried depth of some main pipeline valves is relatively large, and the buried depth of the relief valves on both sides is also large. Such buried relief valves often crack and leak due to factors such as seasonal changes and soil corrosion, and need to be replaced. Due to the large buried depth, in the past, the whole excavation was required for replacement, resulting in a long emergency repair time and a high valve replacement cost. Or a long operation tool was used for remote operation, but such a tool needed to be taken out and re-operated after removing each screw, which was troublesome to use and had low operation efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a rapid emergency repair auxiliary tool for a gas relief valve that can be used for remote continuous disassembly and assembly of screws to improve the emergency repair of gas relief valves at deep or remote positions.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme.

[0005] A rapid emergency repair auxiliary tool for a gas relief valve includes an operation cylinder 1, a force increasing rod 2, a push rod 3, and a one-way positioning assembly 4;

[0006] The operation cylinder 1 is of a cylindrical structure, with a hexagonal hole 1a matching the bolt in the center.

[0008] The one-way positioning assemblies 4 are respectively arranged in the positioning holes 1b;

[0009] The one-way positioning assembly 4 includes a limit block 40 that can slide left and right at the bottom of the positioning hole 1b, a pressure regulating screw 41 at the outer orifice of the positioning hole 1b, and a compression spring between the limit block 40 and the pressure regulating screw 41. The compression spring is in a compressed state and makes the limit block 40 have a tendency to move towards the center of the operation cylinder 1;

[0010] One end of the limiting block 40 pointing to the center of the operating cylinder 1 extends from the bottom of the positioning hole 1b, and a limiting plane 40a is provided at the top of the extended part, and a pressing inclined plane 40b is provided at the bottom.

[0019] The following describes the present invention in detail with reference to specific embodiments.

[0020] The present invention relates to an auxiliary tool for quickly repairing a gas relief valve. This tool can achieve continuous disassembly and assembly operations on multiple screws on the gas relief valve at a relatively long distance, without the need for excavation operations from the side, while preventing the screws from falling, simplifying the disassembly and replacement process of the gas relief valve located in a pit or pipeline, improving the repair efficiency. During one use, multiple screws can be continuously removed and all the screws can be collected. After all the screws are removed, the tool is turned around, and with the cooperation of the push rod, the multiple screws can be pushed out and installed one by one, avoiding the need for repeated picking up, placing, and collecting operations during the single-screw disassembly and assembly process, effectively reducing the auxiliary working time and improving the repair efficiency.

[0021] As shown Figure 1 in the figure, the main structure of the rapid emergency repair auxiliary tool for the gas relief valve of the present utility model includes an operation cylinder 1, a force increasing rod 2, a push rod 3, and a one-way positioning assembly 4;

[0022] The operation cylinder 1 is of a cylindrical structure, and a hexagonal hole 1a matching the bolt is provided in the center. A number of groups of positioning holes 1b are respectively arranged on the inner walls at the upper and lower ends of the operation cylinder 1. Each group of positioning holes includes two positioning holes 1b that are oppositely arranged and have the same height;

[0023] The force increasing rod 2 includes a hexagonal rod body 20 that can extend into the hexagonal hole 1a and a force increasing arm 21 perpendicular to the rod body 20. A through hole 2b is provided in the rod body 20; the push rod 3 can be inserted into the through hole 2b in a vertically sliding manner;

[0024] The one-way positioning assemblies 4 are respectively arranged in the positioning holes 1b;

[0025] The one-way positioning assembly 4 includes a limit block 40 that can slide left and right at the bottom of the positioning hole 1b, a pressure regulating screw 41 at the outer orifice of the positioning hole 1b, and a compression spring between the limit block 40 and the pressure regulating screw 41. The compression spring is in a compressed state and makes the limit block 40 have a tendency to move towards the center of the operation cylinder 1;

[0026] One end of the limit block 40 pointing to the center of the operation cylinder 1 extends out from the bottom of the positioning hole 1b, and a limit plane 40a is provided at the top of the extended part, and an extrusion inclined plane 40b is provided at the bottom.

[0027] The positioning hole 1b is a counterbore, and the large hole end faces outwards, and the small hole end faces towards the center of the operation cylinder 1;

[0028] The hole walls on the left and right sides of the small hole are vertical planes, and the left and right side end faces of the limit block 40 are also vertical planes. The limit block 40 is prevented from rotating through the hole walls on the left and right sides of the small hole.

[0029] For the convenience of assembly and use and to prevent the bolt from getting stuck, in the present utility model, the groups of positioning holes at both ends are arranged at equal intervals, and the height difference between adjacent groups of positioning holes is not less than the height of the bolt on the gas relief valve.

[0030] Particularly, to prevent the bolt from falling out of the hole, when the limit block 40 moves towards the center of the operation cylinder 1 to the extreme position, the length of its extended part is not less than 3.5 mm, and the 3.5 mm extended parts on both sides form a supporting part to prevent the bolt from falling.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
