Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment maintenance technology, and in particular to a threaded coupling disassembly mechanism and drive device. Background Technology

[0002] In the operation and maintenance of hydropower stations, the drainage system is responsible for effectively collecting seepage water, domestic and industrial water, and drainage from unit maintenance within the powerhouse into a sump, and then pumping this water out of the power plant using drainage pumps to ensure the safe and stable operation of the hydropower station. In particular, the long-shaft deep well pump, as a key piece of equipment in the drainage system, directly affects the operational efficiency of the entire drainage system due to its stability and reliability.

[0003] However, disassembling threaded couplings is a challenging task during the routine maintenance and overhaul of long-shaft deep well pumps. As a crucial component connecting the pump body and drive shaft, threaded couplings are often designed with left-hand threads, becoming increasingly tighter as the motor rotates. While this design helps ensure the pump's stability during operation, it also presents significant difficulties for disassembly.

[0004] Traditional disassembly methods primarily rely on tools such as pipe wrenches or spanners, but these tools require finding suitable support points to counteract the reaction force. Because threaded couplings vary in position, the position of pipe wrenches or spanners needs frequent adjustment, significantly increasing the difficulty of disassembly and severely impacting work efficiency. Traditional disassembly methods often require multiple people working together, which not only greatly increases labor costs but also introduces numerous safety hazards. During disassembly, if multiple people do not coordinate properly, accidents such as slips and falls can easily occur when the coupling loosens. Even more seriously, if the coupling cannot be disassembled smoothly, hot work is often required, which undoubtedly further exacerbates the safety risks. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is: due to the different positions of the threaded couplings, the position of the pipe wrench or wrench needs to be adjusted frequently, which not only greatly increases the difficulty of disassembly, but also affects the work efficiency. If the coupling cannot be disassembled, hot work is required.

[0006] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a threaded coupling disassembly mechanism, which includes a fixing unit, including a chuck, a base disposed above the chuck, a telescopic component disposed at one end of the base, and a first fixing member threadedly connected between the chuck and the base;

[0007] The clamping unit includes a clamping assembly disposed above the base, a second fixing member disposed through the clamping assembly, and a fastening assembly disposed in the clamping assembly;

[0008] The fixing unit and the clamping unit are separate units, but they work together to clamp the object.

[0009] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: the top of the base is provided with a protrusion, a circular hole opened at the center of the protrusion, and a chamfer provided at the bottom of the base.

[0010] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: both the chuck and the base are provided with slots.

[0011] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: the telescopic component includes a housing fixedly disposed on the center of the slotted shaft, a piston rod disposed in the inner cavity of the housing, an elastic element disposed on the periphery of the piston rod, and an oil supply pipe opened on the outer wall of the housing.

[0012] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: an annular groove is formed on the outer wall of the housing.

[0013] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: the clamping assembly includes a first clamping member disposed above the base, and a second clamping member disposed on one side of the first clamping member.

[0014] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: both the first clamping member and the second clamping member are provided with circular grooves;

[0015] Both the first clamping member and the second clamping member have teeth, and the two teeth cooperate with each other;

[0016] A limiting groove is provided at one end of the first clamping member.

[0017] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: the fastening assembly includes a ball disposed in the limiting groove, a threaded rod fixedly disposed on one side of the ball, and a nut disposed at one end of the threaded rod.

[0018] In a preferred embodiment of the threaded coupling disassembly mechanism of this utility model: the clamped component includes a sleeve disposed at the shaft center of the fixed unit, and a connecting rod threaded to the top of the sleeve.

[0019] The beneficial effects of this utility model are as follows: Through the cooperation of the split-type disassembly mechanism and the telescopic component, it can flexibly adapt to the disassembly requirements of couplings in different positions, allowing for easy operation by a single person, significantly reducing disassembly difficulty and improving work efficiency. At the same time, it avoids the hot work that may be required in traditional disassembly, ensuring the safety and reliability of the disassembly process and providing an efficient and safe solution for equipment maintenance.

[0020] Another objective of this invention is to provide a driving device that addresses the problem that traditional disassembly methods often require multiple people to work together, which not only significantly increases labor costs but also introduces numerous safety hazards. During disassembly, improper coordination among multiple people can easily lead to accidents such as slipping and falling when the coupling loosens.

[0021] In a preferred embodiment of the driving device of this utility model: the driving unit includes an oil pump and a delivery pipe disposed on one side of the oil pump.

[0022] The beneficial effects of this utility model are: it significantly reduces the high labor costs caused by multiple people working together in traditional disassembly methods, greatly eliminates safety hazards, effectively avoids safety accidents such as personnel slipping and falling caused by improper coordination, and improves disassembly efficiency, which can be achieved by a single person.

[0029] Reference Figures 1-2 This embodiment provides a threaded coupling disassembly mechanism, including a fixing unit 1, including a chuck 11, a base 12 disposed above the chuck 11, a telescopic component 13 disposed at one end of the base 12, and a first fixing member 14 threadedly connected between the chuck 11 and the base 12.

[0030] The clamping unit 2 includes a clamping assembly 21 disposed above the base 12, a second fixing member 22 disposed through the clamping assembly 21, and a fastening assembly 23 disposed in the clamping assembly 21;

[0031] The fixing unit 1 and the clamping unit 2 are separate units, and they work together on the clamped part 3.

[0032] In this embodiment, the chuck 11 is located below the base 12 and the two are separate, and are fixedly connected by a threaded fastener. There is a telescopic component 13 on one side of the top of the base 12.

[0033] The clamping unit 2 is located above the fixing unit 1 and the two are separate and not connected. The second fixing member 22 is inserted through one end of the clamping assembly 21. The clamping assembly 21 rotates around the second fixing member 22. The fastening assembly 23 is located at the other end of the clamping assembly 21 and is located inside the clamping assembly 21.

[0034] The clamped part 3 is positioned between the fixing unit 1 and the clamping unit 2, and they work together on the clamped part 3.

[0035] In use, the clamped part 3 is first erected in a certain place and divided into two parts, the upper part being slightly thinner and the lower part being thicker. First, the fixing unit 1 is inserted through the notch on the fixing unit 1 from the thinner part and slid down to the thicker part. At this time, the fixing unit 1 will be fixed at a certain height of the clamped part 3. The chuck 11 acts as a central fixation to prevent it from shaking during operation, and the base 12 is fixed in a certain position to prevent it from moving upward. The chuck 11 and the base 12 work together to achieve a fixed position. The base 12 is located at the connection between the thicker and thinner parts.

[0036] The clamping unit 2 clamps the thinner end of the clamped part 3 through the clamping assembly 21 and places it on the top of the base 12. The opening size of the clamping assembly 21 is adjusted by the fastening assembly 23, and the clamped part 3 is loosened by the extension rod pushed by the telescopic assembly 13.

[0037] In summary, the fixing unit 1 and clamping unit 2 are separate units with no direct connection, allowing for flexible installation and disassembly. During operation, both units can be adjusted separately, improving work efficiency and reducing operational difficulty. Furthermore, since the fastening component 23 can adjust the opening size of the clamping component 21, this clamping mechanism can accommodate clamped parts of different sizes, demonstrating strong versatility. By using the telescopic component 13 located on one side of the top of the base 12, the clamped part can be loosened by pushing the clamping component 21 with its extended rod. This allows for quick and convenient loosening operations when adjustments or disassembly of the clamped part are needed.

[0038] refer to Figures 1-2 In one embodiment provided in this application, the base 12 is provided with a protrusion 121 on the top, a circular hole 122 opened at the axis of the protrusion 121, and a chamfer 123 provided at the bottom of the base 12.

[0039] As an optional embodiment, both the chuck 11 and the base 12 are provided with slots H.

[0040] As an optional embodiment, the telescopic assembly 13 includes a housing 131 fixedly disposed at the center of the slot H axis, a piston rod 132 disposed in the inner cavity of the housing 131, an elastic element 133 disposed around the piston rod 132, and an oil supply pipe 134 opened on the outer wall of the housing 131.

[0041] As an optional embodiment, an annular groove J is formed on the outer wall of the housing 131.

[0042] In this embodiment, the protrusion 121 is fixedly mounted on the top of one side of the base 12, and a circular hole 122 is provided at the center of the protrusion 121. A groove is provided on one side of the base 12, and the upper part of the groove is cylindrical, and a chamfer 123 is provided at the bottom. The chamfer 123 is mainly used to make the connection between the thicker part and the thinner part tighter and to prevent the fixing unit 1 from shaking. The chuck 11 and the base 12 are both provided with slots H, and the first fixing member 14 is threaded through the slots H.

[0043] The telescopic component 13 is located at the center of the circular hole 122 and cooperates with the circular hole 122. The outer wall of the housing 131 away from the base 12 is provided with an oil supply pipe 134. The piston rod 132 is located inside the housing 131, and the elastic element 133 is located on the periphery of the piston rod 132. The tail of the piston rod 132 is cylindrical and cooperates with the inner wall of the housing 131. The oil supply pipe 134 communicates with the inner cavity of one end of the housing 131. An annular groove J is provided on the outer wall of the housing 131 near the base 12 and cooperates with the protrusion 121 to play a fixing role.

[0044] As an optional embodiment, the clamping assembly 21 includes a first clamping member 211 disposed above the base 12, and a second clamping member 212 disposed on one side of the first clamping member 211.

[0045] As an optional embodiment, both the first clamping member 211 and the second clamping member 212 are provided with circular grooves K;

[0046] Both the first clamping member 211 and the second clamping member 212 are provided with teeth L, and the two teeth L cooperate with each other;

[0047] The first clamping member 211 has a limiting groove N at one end.

[0048] As an optional embodiment, the fastening assembly 23 includes a ball 231 disposed in the limiting groove N, a threaded rod 232 fixedly disposed on one side of the ball 231, and a nut 233 disposed at one end of the threaded rod 232.

[0049] As an optional embodiment, the clamped member 3 includes a sleeve 31 disposed at the axis of the fixing unit 1, and a connecting rod 32 threadedly connected to the top of the sleeve 31.

[0050] In this embodiment, the clamping assembly 21 is disposed above the base 12 and includes a first clamping member 211 and a second clamping member 212. The first clamping member 211 and the second clamping member 212 are provided with a circular groove K and a tooth L. The two teeth L cooperate with each other. A groove is provided in the middle of one end of the first clamping member 211, and one end of the second clamping member 212 is disposed in this groove. The second fixing member 22 passes through the circular groove K of the first clamping member 211 and the second clamping member 212. When the first clamping member 211 is placed in a certain position, the second clamping member 212 can clamp the clamped part 3 with the second fixing member 22 as the center.

[0051] A limiting groove N is formed at one end of the first clamping member 211. A ball 231 is set in the limiting groove N. One end of the threaded rod 232 is fixedly connected to one side of the ball 231, and the other end can be rotated to the second clamping member 212 for fixation in a horizontal position. When the threaded rod 232 moves to the second clamping member 212, it is tightened by rotating the nut 233 to achieve the fixing effect of the clamped member 3.

[0052] The sleeve 31 is located below the connecting rod 32 and is connected to it by threads. The clamping assembly 21 is clamped at the position of the connecting rod 32. The fixing unit 1 is located on the sleeve 31, wherein the chamfer 123 in the bottom of the base 12 cooperates with the end of the sleeve 31 to play a fixing role.

[0053] During use, during installation, first connect the chuck 11 and the base 12 with the first fixing member 14 by thread. Then, insert the connected assembly through the notch on the top into the position of the connecting rod 32 and slide it down to the position of the sleeve 31. Next, connect the clamping assembly 21 together with the second fixing member 22. First, open the first clamping member 211 and the second clamping member 212 around the second fixing member 22. When the connecting rod 32 is placed at the center of the two teeth L, rotate the second clamping member 212 so that the two teeth L are tightly attached to the connecting rod 32. After rotating the ball 231 or the threaded rod 232 to the designated position, rotate the nut 233 on the threaded rod 232 so that it is tightly attached to the second clamping member 212. Oil is delivered to the inner cavity of the housing 131 through the oil supply pipe 134 in the telescopic assembly 13, which squeezes the elastic member 133 and the telescopic rod 132, causing the telescopic rod 132 to move horizontally and push one side of the first clamping member 211 to achieve the purpose of loosening.

[0054] In summary, the separate design of the fixing unit 1 and the clamping unit 2, with no direct connection between them, allows for independent and flexible installation and disassembly. The fixing unit 1 and the clamping unit 2 can be adjusted separately, significantly improving operational efficiency and reducing difficulty. Combined with the adjustable opening threaded rod 232 and ball 231 structure in the fastening assembly 23, and the hydraulically driven piston rod 132 in the telescopic assembly 13, it can not only clamp clamped parts 3 of different sizes, but also deliver oil to the inner cavity of the housing 131 through the oil supply pipe 134, squeezing the elastic element 133 and the piston rod 132, causing the piston rod 132 to horizontally move and push one side of the first clamping member 211, thereby achieving rapid loosening of the clamped part 3 and greatly optimizing the convenience of clamping and releasing. Meanwhile, the chuck 11 and the base 12 are fixed by the threaded connection of the slot H, the bottom chamfer 123 of the base 12 cooperates with the sleeve 31 end of the clamped part 3, and the annular groove J on the outer wall of the housing 131 is firmly fixed with the protrusion 121 of the base 12, which further enhances the compatibility of the mechanism with parts of different sizes and shapes.

[0055] refer to Figures 1-3 In one embodiment provided in this application, the drive unit 4 includes an oil pump 41 and a delivery pipe 42 disposed on one side of the oil pump 41.

[0056] In this embodiment, the oil pump 41 and the delivery pipe 42 are fixedly connected to ensure the sealing between them. The other end of the delivery pipe 42 is connected to the oil delivery pipe 134 in the telescopic assembly 13, forming a complete disassembly device. By controlling the oil pump 41, the delivery power can be flexibly adjusted, thereby achieving accurate control over the extension length and speed of the telescopic assembly 13.

[0057] In use, the operator only needs to reliably connect the delivery pipe 42 of the oil pump 41 to the oil delivery pipe 134 of the telescopic component 13, and can easily adjust the telescopic characteristics of the telescopic component 13 by adjusting the output power of the oil pump 41.

[0058] In summary, compared to traditional disassembly methods, the drive unit 4, powered by the oil pump 41, significantly reduces manpower, lowers costs, and improves efficiency. Furthermore, the use of the drive unit 4 ensures operator safety during the disassembly process.

[0059] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
