Description

Technical Field

[0001] This utility model relates to the field of gas pipeline safety inspection equipment, and in particular to an auxiliary component for gas valve well inspection. Background Technology

[0002] During gas pipeline inspections, inspectors must carry at least two types of valve opening and closing devices, including specific tools for PE valves and gate valves. Because there is often a height difference between the valves and the worker's standing surface, the opening and closing devices are often equipped with long connecting rods, making them generally large and heavy, increasing the worker's load and making them inconvenient to carry.

[0003] Especially in scenarios involving complex terrain, confined spaces, or long-distance inspections, the inconvenience of carrying tools not only reduces operational efficiency but may also affect the timeliness of emergency response. Currently, most line patrol operations are conducted by motorcycle, meaning they are carried out using electric bikes or motorcycles. As mentioned above, these drawbacks have become the biggest pain points in line patrol work.

[0004] There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an auxiliary component for inspecting gas valve wells that is simple in structure, quick and flexible in assembly and disassembly, can be integrated and carried, and is especially suitable for riding patrol operations.

[0006] The equipment includes a screw-on connector, a connecting rod unit, a fixing component, and an opening / closing key assembly; The aforementioned screwing connection includes a force-adding rod and a screwing sleeve. The screwing sleeve is a sleeve structure with a sleeve on its upper part and a force-adding rod passing through the sleeve. The lower part of the rotating sleeve is connected to a connecting rod unit via a fastener. The connecting rod unit is composed of multiple connecting rods connected in sequence, and the connecting rods are fixedly connected to each other by fasteners. The opening and closing key assembly includes at least a manhole cover opening and closing key, a PE valve key, and a gate valve opening and closing key, and any of the above keys can be movably connected to the connecting rod and fixed by a fastener.

[0007] The effect achieved is that, based on the rapid assembly and connection of standardized fasteners, the entire device can be quickly assembled and disassembled, facilitating on-site assembly and easy disassembly for storage and transport. Furthermore, based on the above, the device has a higher degree of integration, capable of performing valve opening and closing for most line inspection tasks using the key-operated assembly, and its configuration is shown in the attached diagram in the manual. Figure 1 As shown, when the valve is opened or closed, the operator is naturally positioned to the side of the valve to avoid impact injury.

[0008] The beneficial effects of this utility model are: it solves the problem of inconvenience caused by the large number, size, and weight of items carried by patrol personnel in the prior art. Through flexible disassembly and assembly, it achieves rapid disassembly, assembly, and integrated storage of the equipment. It is especially suitable for carrying while on patrol, and the equipment has a simple structure and low cost. Attached Figure Description

Detailed Implementation

[0010] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The auxiliary component for inspecting gas valve wells according to this utility model includes a screw-on connection part 1, a connecting rod unit 2, a fixing part 4, and an opening and closing key assembly 3. The screwing connection 1 includes a force-adding rod 11 and a screwing sleeve 12. The screwing sleeve 12 is a sleeve structure with a sleeve on its upper part and a force-adding rod 11 passing through the sleeve. The lower part of the rotating sleeve 12 is connected to a connecting rod unit 2 via a fixing member 4. The connecting rod unit 2 is composed of multiple connecting rods 21 connected in sequence, and the connecting rods 21 are fixedly connected to each other by the fixing member 4. The opening and closing key assembly 3 includes at least a manhole cover opening and closing key 33, a PE valve key 31, and a gate valve opening and closing key 32, and any of the above keys can be movably connected to the connecting rod 21 and fixed by the fixing member 4.

[0011] The effect achieved is that, based on the quick assembly and connection of the uniformly sized fasteners 4, the entire device can be quickly assembled and disassembled, facilitating on-site assembly and disassembly for storage and transport. Furthermore, based on the above, the device has a higher degree of integration, capable of performing the valve opening and closing of most pipeline inspection tasks using the key assembly 3, and its configuration is shown in the attached diagram of the instruction manual. Figure 1 As shown, when the valve is opened or closed, the operator is naturally positioned to the side of the valve to avoid impact injury.

[0012] In Example 1, the rotating sleeve 12 is a square tube or a spline tube, and the force-applying rod 11 is fitted to its inner cavity surface.

[0013] The effect achieved is to ensure that the force-applying rod 11 and the rotating sleeve 12 fit tightly together, which serves to stop rotation and facilitate the application of force.

[0014] In embodiment 2, the connecting rod 21 is integrally formed, and its upper part is a sleeve connecting part, in which a slot is provided; The bottom of the connecting rod 21 is provided with a corresponding slot insert, and an assembly hole is provided on the sleeve connection part; The fastener 4 is installed in the assembly hole, thereby realizing the sequential connection of the connecting rods 21.

[0015] Furthermore, the lower part of the rotating sleeve 12 is provided with an insert block that has the same size as the bottom of the connecting rod 21.

[0016] This enables a quick connection between the screw-on connecting part 1 and the connecting rod unit 2.

[0017] Furthermore, the insert is a cuboid insert, and the slot is fitted to fit the insert.

[0018] The effect achieved is a quick connection, and unlike existing threaded connection technology products, the equipment itself will not have the problem of self-rotation and decoupling when driving the valve in both forward and reverse directions.

[0019] Furthermore, the fixing member 4 is a spring pin, and the insert block is provided with a pin hole corresponding to the spring pin shaft.

[0020] This ensures the rapid assembly and connection of the equipment.

[0021] Preferably, the spring pin can also be replaced by a hard limit bolt.

[0022] In Example 3, the manhole cover opening and closing key 33, the PE valve key 31, and the gate valve opening and closing key 32 are all integrally set, and each key has a base on its top, with a slot for a corresponding insert block inside the base.

[0023] This enables a quick connection between the key assembly 3 and the connecting rod unit 2.

[0024] Furthermore, refer to the accompanying drawings in the instruction manual. Figure 4 The manhole cover opening and closing key 33 is in the form of a hook.

[0025] The effect achieved in this way is to execute the opening and closing action of the manhole cover.

[0026] Furthermore, refer to the accompanying drawings in the instruction manual. Figure 4 The PE valve key 31 is in the form of a sleeve. The inner diameter of the bottom surface of the sleeve gradually narrows from bottom to top, forming a frustum-shaped structure. A locking groove corresponding to the size of the PE valve is provided on its top surface.

[0027] This enables the rapid identification and opening / closing of PE valves.

[0028] Preferably, the PE valve key 31 is available in various specifications corresponding to the valve size.

[0029] Furthermore, refer to the accompanying drawings in the instruction manual. Figure 4 The gate valve opening and closing key 32 includes a sleeve integrally connected to the base, and curved rods are respectively sleeved at both ends of the sleeve. The curved rods are in the form of right-angle curved rods bent downwards, and a hard limit bolt or spring pin is provided between the curved rods and the sleeve.

[0030] This allows the gate valve to be opened and closed by turning it, while also adjusting the distance between its two cranks to accommodate gate valves of different sizes.

[0031] Example 4, refer to the accompanying drawings in the specification. Figure 5 The aforementioned connecting part, connecting rod unit 2, fixing part 4 and opening / closing key assembly 3 are integrated and stored in a toolbox; The toolbox is equipped with a latch and is hinged for opening and closing. Its inner cavity is provided with an elastic pad, and a storage slot corresponding to each of the above-mentioned components is opened in the elastic pad.

[0032] This is how the equipment can be integrated and stored.
