Description

Technical Field

[0001] This utility model relates to the technical field of top screw disassembly and assembly tools, specifically a special tool for disassembling and assembling top screws of shale gas venting plates. Background Technology

[0002] Currently, most gas gathering stations use orifice valves to measure shale gas production. Orifice valves have a simple structure and reliable sealing performance. Their main maintenance tasks include replacement, cleaning, and inspection, requiring disassembly and assembly of the top plate valve. Disassembly and assembly involve different operations such as opening and closing the vent valve, operating the lifting shaft, and removing the set screws. Traditionally, this requires the use of multiple tools, including crank handles and Allen wrenches. Furthermore, because orifice valves come from different manufacturers and have different specifications, the set screws also come in various sizes, requiring different sizes of Allen wrenches to be carried during maintenance, resulting in low work efficiency.

[0003] Therefore, a combination tool is needed that is easy to carry and can quickly disassemble and assemble the top plate valve. Utility Model Content

[0004] This utility model provides a special tool for disassembling and assembling the top screw of a shale gas vent plate. This special tool integrates multiple disassembly and assembly tools, which can reduce the number of tools to carry, is easy to use, and effectively improves the working efficiency of disassembling and assembling the top plate valve.

[0005] This application provides the following technical solution: A special tool for disassembling and assembling shale gas vent plate top screws includes a tool body, a crank handle, and a functional head. The functional head is detachably connected to the tool body. The functional head has an upper connecting part and a lower connecting part. The upper connecting part is a hexagonal boss corresponding to an internal hex wrench. The lower connecting part is detachably connected to the tool body.

[0006] Technical principle: The special tool is designed as a combination, including the tool body and the functional head. The upper part of the functional head is designed in the shape of different sizes of internal hex wrenches. The lower part of the functional head is detachably connected to the tool body. The tool body is also equipped with a crank handle.

[0007] Beneficial effects: By selecting different functional heads, the combination tool can achieve the functions of different sizes of Allen wrenches. The tools carried have changed from multiple traditional wrenches to a tool body + multiple functional heads, reducing the number and volume of tools to carry and making it more convenient for workers to operate. At the same time, the crank handle on the tool body is more conducive to disassembly and assembly operations. The combination tool can more easily adjust the direction and force of the applied force, improve the uniformity of force during the disassembly and assembly of set screws, reduce set screw damage caused by brute force disassembly and assembly, and save on parts replacement costs.

[0008] Furthermore, the tool body is a long strip with a curve at one end, with the curved end forming a first mounting part and the other end forming a second mounting part, and the functional head is detachably connected to the first mounting part.

[0009] Beneficial effects: The first mounting section and the second mounting section are designed as different functional areas. The first mounting section is used to remove the set screw. In order to adapt to different specifications of set screws, different functional heads are configured. The functional heads can be easily replaced for disassembly and assembly operations according to different set screw specifications through a detachable connection.

[0010] Furthermore, the first mounting part is a cylindrical functional head mounting base with a hexagonal groove inside, and its side is welded to the end of the tool body. The lower connecting part of the functional head is a hexagonal boss that matches the hexagonal groove of the base.

[0011] Beneficial effects: The groove of the mounting base and the protrusion of the functional head connection part enable quick connection. At the same time, the shape of the groove can ensure that the functional head is effectively limited and will not rotate relative to the mounting base, thus reliably realizing the function of the hex wrench.

[0012] Furthermore, a functional head grip portion is formed on the middle side of the functional head, and the diameter of the functional head grip portion is the same as the outer diameter of the functional head mounting base.

[0013] Beneficial effect: The function head grip allows operators to easily install and remove the function head without additional tools.

[0014] Furthermore, the second mounting part is a sleeve with a square groove, the size of which matches the outer dimensions of the vent valve.

[0015] Beneficial effects: The second mounting section is equipped with a square sleeve, which can be fitted onto the vent valve for on / off operation.

[0016] Furthermore, the tool body has a crank handle through hole with internal threads at one end near the second mounting part, and the top of the crank handle has external threads. The crank handle is connected to the tool body through the crank handle through hole and a nut.

[0017] Beneficial effects: The crank handle and the tool body are connected by threads, which is simple in structure, reliable in connection, and has low processing cost.

[0018] Furthermore, the lower end of the crank handle is a crank grip portion, and the surface of the crank grip portion is decorated with a mesh-like anti-slip texture or is sandblasted.

[0019] Beneficial effects: The handle surface is treated with an anti-slip coating to increase friction and prevent slippage when gripping and applying force, thus avoiding interference with disassembly and assembly operations.

[0020] Furthermore, a transition section with a gradually changing diameter is formed between the crank grip portion and the top of the crank handle.

[0021] Furthermore, the tool body is made of 45# steel, and the functional head is made of Q235 steel.

[0022] Beneficial effects: Selecting suitable materials ensures that the combination tools have sufficient strength to withstand the torque and impact during assembly and disassembly, while also possessing good wear resistance and machinability.

[0023] Furthermore, a strong magnetic sheet is provided on the bottom surface of the lower connecting part.

[0024] Beneficial effects: It further improves the integration of the combination tools and reduces storage volume. Attached Figure Description

[0025] Figure 1 A schematic diagram of the tool body and crank handle structure of a special tool for disassembling and assembling the top screw of a shale gas vent plate; Figure 2 This is a schematic diagram of the functional head. Detailed Implementation

[0026] The following detailed description illustrates the specific implementation method: The markings in the accompanying drawings include: crank handle 1, tool body 2, first mounting part 3, second mounting part 4, upper connecting part 5, functional head grip part 6, and lower connecting part 7.

[0027] Example 1 A special tool for disassembling and assembling shale gas vent plate top screws includes a crank handle 1, a tool body 2, and a functional head, the structure of which is as follows: Figure 1 As shown.

[0028] The tool body 2 is made of 45# stainless steel and can withstand the torque and impact during disassembly and assembly. The overall shape of the tool body 2 is a long strip with a curve at one end. The curved end forms the first mounting part 3, and the other end forms the second mounting part 4.

[0029] The first mounting part 3 is used to fix the functional head for installing and removing the set screw. In this embodiment, the first mounting part 3 is designed as a functional head mounting base. The functional head mounting base is cylindrical in shape and has a hexagonal groove inside. Its side is welded to the end of the tool body. The height of the first mounting part 3 is greater than the thickness of the tool body 2, which can effectively prevent interference between the tool body 2 and the top plate valve when installing and removing the set screw.

[0030] The functional head for installing and removing set screws is made of Q235 steel, possessing good strength and wear resistance. The functional head uses... Figure 2The cylindrical structure shown has a diameter identical to the outer diameter of the functional head mounting base. The side of the cylinder forms the functional head grip 6, and its surface is sandblasted. The upper and lower ends of the functional head are respectively provided with an upper connecting part 5 and a lower connecting part 7. The upper connecting part 5 is a hexagonal boss, and the shape of the upper connecting part 5 for different functional heads corresponds to different sizes of internal hex wrenches, including M14, M16, M18, and M20. The lower connecting part 7 is a hexagonal boss that matches the hexagonal groove of the functional head mounting base. When the lower connecting part 7 is inserted into the hexagonal groove, the functional head is limited by the hexagonal groove and will not rotate relative to the tool body 2, allowing it to be firmly combined with the tool body 2. Rotating the tool body 2 enables the function of an internal hex wrench. To disassemble or assemble different sizes of set screws, only the functional head needs to be replaced. To facilitate identification of different functional head sizes, markings or numbers can be set on the lower connecting part.

[0031] It is understood that the groove of the mounting base and the lower connecting part of the functional head can also be designed in other shapes, such as triangle, quadrilateral, cross, etc., as long as the corresponding structure can provide a reliable limiting function.

[0032] The second mounting part 4 is used to switch the vent valve on and off. In this embodiment, the second mounting part 4 is designed as a sleeve with a square groove, the size of which matches the outer dimensions of the vent valve. The outer diameter of the sleeve is the same as the width of the tool body 2, and the end face of the tool body 2 is provided with an arc-shaped concave surface. The side of the sleeve is welded to the arc-shaped concave surface of the tool body 2.

[0033] The tool body 2 has a crank handle through hole with internal threads at one end near the second mounting part 4 for mounting the crank handle 1. The crank handle 1 has a cylindrical structure, with the top diameter being the same as the diameter of the crank handle through hole and having external threads. It can be inserted into the crank handle through hole in a direction perpendicular to the tool body 2 and is fixedly connected to the tool body 2 by threads and a nut. The lower end of the crank handle 1 is the crank grip part. The surface of the crank grip part can be provided with a mesh anti-slip texture or sandblasted to increase friction. A transition part with a gradually changing diameter is formed between the crank grip part and the top of the crank handle.

[0034] In actual use, screw the upper end of the crank handle into the mounting through hole and secure it with a nut. Select a suitable size functional head and insert its lower connecting part 7 into the functional head mounting base to complete the assembly of the special tool. Different functional heads can be quickly changed using the functional head grip part 6.

[0035] When disassembling the set screw, connect the upper connecting part 5 of the functional head to the set screw as an Allen wrench. Hold the handle 1 with one hand to apply force, and use the other hand to assist in fixing the tool body 2. Rotate the handle 1 around the functional head axis, ensuring the axis of the handle 1 is parallel to the functional head axis, allowing the entire tool to easily apply force. At this time, the portion of the tool body 2 between the functional head axis and the handle axis forms the lever arm for disassembling the set screw, significantly saving the effort required and effectively reducing the worker's labor intensity. When operating the vent valve, fit the sleeve groove of the second mounting part 4 onto the vent valve. Hold the handle 1 vertically with one hand, and the first mounting part 3 with the other hand. Rotate the tool body 2 around the sleeve axis. During disassembly, the set screw can be gradually unscrewed by rotating the handle 1; during installation, the set screw can be gradually screwed in by rotating the handle 1 to achieve the predetermined tightening torque.

[0036] Practical testing has shown that this specialized tool has a longer lever arm than traditional hex wrenches, making it easier to remove set screws. This effectively prevents damage to the set screws from brute force during installation and removal, reduces the frequency of parts replacement, and saves costs. Furthermore, the two-handed operation ensures even force distribution on the set screws, improving the levelness of the installation. The quick-change function head further enhances operational efficiency.

[0037] Example 2 The main difference between this embodiment and Embodiment 1 lies in the lower connecting part 7.

[0038] To further improve the convenience of the combination tool, a strong magnetic sheet is fixedly connected to the ground of the lower connecting part 7. The strong magnetic sheet is circular in shape and is embedded in the bottom surface of the lower connecting part 7, with the surface of the strong magnetic sheet consistent with the bottom surface of the lower connecting part 7.

[0039] When the connecting part is inserted into the mounting base, the magnetic force provided by the strong magnet helps the functional head to connect more firmly to the mounting base, improving the reliability of the combination tool. When it is not necessary to remove the set screw, the functional head can be reversed so that its bottom surface contacts the lower surface of the tool body 2, and the functional head is attracted to the tool body 2 by magnetic force, achieving quick storage.
