Description

Technical Field

[0001] The present disclosure relates to the technical field of compressor piston rod disassembly and assembly, and in particular to a disassembly and assembly device. Background Art

[0002] The circulating gas compressor adopts a horizontal symmetrical layout of the first and second cylinders to ensure smooth operation. A packing seal is used between the compressor cylinder and the piston rod. Once the seal fails, the compressed medium containing high concentrations of carbon monoxide and hydrogen will face the risk of leakage. However, in the long-term operation of reciprocating compressors, wear of packing rings, oil scraper rings and piston rods is a common problem, which not only leads to a decrease in sealing performance, but also may cause serious oil leakage. In view of this, the equipment needs to undergo at least two major overhauls each year, among which the disassembly and assembly of the piston assembly is a necessary part of the maintenance process.

[0003] At the threaded connection between the piston rod and the crosshead, every time disassembly is required, the operator can only use a wrench to clamp and remove the lock nut through the inspection window located on the middle seat of the cylinder body. Due to the limited space provided by the inspection window, the wrench cannot completely rotate continuously around the axis of the cylinder body and can only rotate at a small angle. In addition, during this disassembly process, the specific location of the inspection window is particularly important because it directly determines the feasibility and efficiency of the disassembly operation. This significantly prolongs the disassembly and assembly time of each threaded connection. Considering that there are multiple such connections in the first and second cylinders, the entire disassembly and assembly process takes a long time, which in turn affects the overall production efficiency and economic benefits.

[0004] Therefore, how to provide a disassembly device that can rotate continuously without being restricted by space is a problem that urgently needs to be solved. Utility Model Content

After rotating the handheld component so that it can be carried by the connecting rod to continuously rotate the sleeve component around the axis of the connecting rod for several circles, the locking nut can be easily disassembled or assembled.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] When removing the locking nut used to connect the piston rod and the crosshead in the compressor, the space of the cylinder body is long and narrow, and the wrench can only be inserted into the cylinder body through the inspection window in the middle of the cylinder body and rotated at a small angle to remove and install the locking nut. The inventor wants to design a disassembly device that is not limited by the inspection space, is suitable for cylinders of different sizes, and can rotate continuously during disassembly and assembly.

[0032] The embodiment of the present disclosure provides a disassembly and assembly device, including: a clamping sleeve component 1, which is provided with a accommodating cavity 11 and the inner cavity wall of the accommodating cavity 11 is relatively provided with at least two clamping parts 12; a connecting rod 2, one end of which is detachably connected to the end of the clamping sleeve component 1 opposite to the accommodating cavity 11, and the connecting rod 2 can be retracted along its extension direction; a hand-held component 3, which is detachably connected to the end of the connecting rod 2 opposite to the clamping sleeve component 1.

[0033] Specifically, Figure 1-Figure 5 As shown, the accommodating cavity 11 of the ferrule component 1 is adapted to the part to be disassembled, and the size and shape of the ferrule component 1 can be set according to the size and shape of the part to be disassembled, such as: the cross-sectional shape of the accommodating cavity 11 is hexagonal, circular, etc., and the part to be disassembled includes but is not limited to a fastening nut. The ferrule component 1 includes a accommodating cavity 11, and at least two clamping parts 12 are provided on the inner cavity wall thereof. The clamping parts 12 are the parts that contact with the part to be disassembled and are used to clamp the part to be disassembled. The clamping parts 12 can be abutting surfaces 121, protrusions, grooves, claws or other forms of structures, which are used to match the specific features of the part to be disassembled, so as to achieve firm clamping and fixing. The connecting rod 2 is used to connect the ferrule component 1 and the handheld component 3, and is the operating lever of the disassembly and assembly device. One end of the connecting rod 2 is detachably connected to the ferrule component 1, and the detachable connection here can be achieved by a mortise and tenon structure or a threaded structure.

[0034] In addition, the connecting rod 2 can be telescopic along its extension direction. The specific implementation is as follows: the connecting rod 2 includes two or more first pipe sections and second pipe sections that are mutually nested, wherein the inner diameter of the first pipe section is slightly larger than the outer diameter of the second pipe section, so that the second pipe section slides in the first pipe section. In addition, the inner wall of the first pipe section is provided with a plurality of radial holes, and the second pipe section has one or more buttons that can be popped out and adapted to the holes of the first pipe section. When the second pipe section slides to a preset position, the button will pop into the corresponding hole, thereby fixing the telescopic second pipe section. When unlocking, press the button to retract it into the second pipe section, and the second pipe section can continue to slide relative to the first pipe section. The shape of the handheld component 3 can be set according to the user's habits, such as: the handheld component 3 is a T-shaped rod or a handwheel 4. The connecting rod 2 and the handheld component 3 can be detachably connected, and can be detachably connected through a mortise and tenon structure or a threaded structure, allowing maintenance personnel to replace it according to specific application scenarios or user's personal preferences.

[0035] The disassembly and assembly device provided by the present disclosure includes a sleeve component 1, a connecting rod 2 and a handheld component 3. During disassembly and assembly, the maintenance personnel can extend the sleeve component 1 from the inspection window in the middle of the cylinder body and clamp the locking nut at the end of the piston rod, or extend it from the installation port at the tail end of the cylinder body into the cylinder body and clamp the locking nut at the end of the piston rod, and the axis of the sleeve component 1 is parallel to or coincides with the axis of the cylinder body. After rotating the handheld component 3 so that it can be rotated continuously around the axis of the connecting rod 2 with the sleeve component 1 through the connecting rod 2 for several circles, the locking nut can be easily disassembled or assembled. The connecting rod 2 of the disassembly and assembly device can be freely telescopically adjusted with the length of the cylinder body and the position of the maintenance space, and the clamping method of the sleeve component 1 and the locking nut enables the maintenance personnel to continuously rotate the handheld component 3 around the axis of the cylinder body to disassemble or assemble the locking nut. Therefore, the disassembly and assembly device can be continuously rotated without space restriction, which simplifies the operation of the locking nut in a small space and improves the maintenance efficiency.

[0036] In some embodiments, the clamping portion 12 includes: two abutting surfaces 121 , which are spaced apart from each other on the inner cavity wall and form an angle.

[0037] Specifically, the clamping portion 12 may include two abutting surfaces 121. The shape of the abutting surfaces 121 may be set according to the shape of the part to be disassembled, and the angle formed between the two abutting surfaces 121 may be adjusted according to the contour of the part to be disassembled. For example, if the part to be disassembled has a protruding edge or angle, the angle between the two abutting surfaces 121 may match this feature, thereby more firmly clamping or clamping the part to be disassembled. By designing the clamping portion 12 as two abutting surfaces 121, the clamping portion 12 can be made to fit more closely to the surface of the part to be disassembled, thereby achieving more secure clamping or clamping, and ensuring that the part remains stable during the disassembly process. In addition, if Figure 1 As shown, one clamping portion 12 may include three abutting surfaces 121 , and two adjacent abutting surfaces 121 may be arranged at intervals or adjacent to each other.

[0038] In some embodiments, the engaging portion 12 is a slot 122 extending in a direction away from the accommodating cavity 11 .

[0039] Specifically, Figure 1 As shown, when the part to be disassembled has corners, the clamping portion 12 can be a clamping groove 122 set in the accommodating cavity 11. The clamping groove 122 extending in the direction away from the accommodating cavity 11 is adapted to the corners of the part to be disassembled. When the clamping sleeve component 1 is clamped on the part to be disassembled, the clamping groove 122 can provide a clear positioning point for the part to be disassembled and quickly clamp the angle of the part to be disassembled, ensuring that the part to be disassembled is correctly aligned and fixed with the clamping sleeve component 1 to avoid misalignment.

[0040] In some embodiments, two avoidance openings 13 are disposed opposite to each other on the cavity wall of the accommodating cavity 11 .

[0041] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, in order to avoid the fixing pin of the compressor piston rod fixing nut, two avoidance openings 13 are relatively provided on the cavity wall of the accommodating cavity 11 of the sleeve component 1, which can ensure that the sleeve component 1 will not interfere with the fixing pin when fixing and operating the disassembled parts. The shape and size of the avoidance opening 13 need to match the shape and size of the fixing pin. For example, if the fixing pin is cylindrical, the avoidance opening 13 can be designed to be circular or elliptical; if the fixing pin is a square or other shaped pin, the avoidance opening 13 can be designed to be square or other matching shapes accordingly. In addition, the size of the avoidance opening 13 needs to be slightly larger than the cross-section of the fixing pin to ensure that there is enough space to avoid the pin and avoid unnecessary friction or collision during operation.

[0042] In some embodiments, a weight-reducing groove 14 is provided on the wall of the accommodating cavity 11 .

[0043] Specifically, Figure 1 or Figure 4 As shown, in order to reduce the overall weight of the disassembly and assembly device and improve the flexibility during operation, a weight-reducing groove 14 is provided on the cavity wall of the accommodating cavity 11, and these weight-reducing grooves 14 can be arranged between two adjacent clamping grooves 122 or on the abutting surface 121. The weight-reducing groove 14 can significantly reduce the total weight of the clamping sleeve component 1 by removing materials not used for fixing the clamping area, which is particularly beneficial for scenes that require long-term hand-held operation, reducing the burden on maintenance personnel and improving work efficiency.

[0044] In some embodiments, the connecting rod 2 includes: at least two supporting rods 21, which are connected in sequence along the extending direction of the connecting rod 2 and two adjacent supporting rods 21 are connected by threads.

[0045] Specifically, Figure 1-Figure 4 As shown, in order to enable the sleeve component 1 of the disassembly and assembly device to extend into the cylinder of compressors of different sizes to disassemble and assemble the fastening nuts, the connecting rod 2 includes at least two support rods 21, and the operator can select the number of assembly of the support rods 21 according to the length of the cylinder and the relative position of the fastening nuts. Two adjacent support rods 21 can be connected by threads, and matching threads are set on the two adjacent support rods 21. The disassembly and installation of the two support rods 21 can be achieved by rotating the support rods 21. This modular design enables maintenance personnel to adjust the total length of the connecting rod 2 by increasing or decreasing the number of support rods 21 according to actual needs, thereby adapting to various work scenarios. For example, in an environment with limited space, the length of the connecting rod 2 can be shortened by reducing the number of support rods 21 to obtain better operational flexibility.

[0046] In some embodiments, the connecting rod 2 includes: a connecting rod 22, which is provided with a cavity, and the rod wall of the connecting rod 22 is provided with a plurality of sockets 25 and the hole wall of each socket 25 is provided with a thread; a sliding rod 23, whose tube diameter is smaller than the tube diameter of the connecting rod 22, and is sleeved in the cavity of the connecting rod 22 and can slide relative to the extension direction of the connecting rod 22; and a locking pin 24, which has a preset length and whose outer peripheral surface is provided with a thread adapted to the socket 25, and is used to be inserted into the socket 25 so that one end of it abuts against the sliding rod 23 to lock the sliding rod 23 to the connecting rod 22.

[0047] Specifically, Figure 5 As shown, in order to enable the sleeve component 1 of the disassembly and assembly device to extend into the cylinder of compressors of different sizes to disassemble and assemble the fastening nut, the connecting rod 2 may include a connecting rod 22 and a sliding rod 23, and the connecting rod 22 cooperates with the sliding rod 23 to achieve telescopic movement. The connecting rod 22 is provided with a cavity, and a plurality of radial insertion holes 25 are arranged at intervals on the rod wall of the connecting rod 22, and the hole wall of the insertion hole 25 is provided with a thread for subsequent cooperation and fixation with the locking latch 24. The sliding rod 23 is sleeved with the connecting rod 22, and the outer diameter of the sliding rod 23 is slightly smaller than the inner diameter of the connecting rod 22. The sliding rod 23 can slide in the connecting rod 22 so that the operator can adjust the length of the connecting rod 2 as needed. The outer peripheral surface of the locking latch 24 is provided with a thread adapted to the insertion hole 25 of the connecting rod 22. When the operator slides the slide bar 23 to the preset position, the locking pin 24 can be inserted into the insertion hole 25 at the corresponding position of the connecting rod 22, and the locking pin 24 can be rotated so that one end of the locking pin 24 abuts against the slide bar 23, and the other end is fixed to the connecting rod 22 through a thread. This structure ensures that the slide bar 23 is fixed in the connecting rod 22, preventing the slide bar 23 from moving accidentally during use.

[0048] In some embodiments, the connecting rod 2 is a hollow structure.

[0049] Specifically, the connecting rod 2 is a hollow structure (not shown in the figure), which can reduce the weight of the device, reduce the use of materials, and reduce costs. In addition, reducing weight can improve the convenience of operation and reduce fatigue.

[0050] In some embodiments, the hand-held component 3 includes: a first connecting section 31, extending along the extension direction of the connecting rod 2, one end of which is connected to the connecting rod 2; a second connecting section 32, extending along a direction perpendicular to the extension direction of the connecting rod 2 and one end of which is connected to an end of the first connecting section 31 away from the connecting rod 2; a hand grip 33, extending along the extension direction of the connecting rod 2, one end of which is connected to an end of the second connecting section 32 away from the first connecting section 31.

[0051] Specifically, Figure 5As shown, the first connecting section 31 extends along the extension direction of the connecting rod 2, and one end of the first connecting section 31 is connected to the connecting rod 2, usually by threaded connection, buckle or other mechanical connection methods. The second connecting section 32 is a transition section from the connecting rod 2 to the hand grip 33, extending perpendicular to the extension direction of the connecting rod 2, and one end of the second connecting section 32 is connected to the end of the first connecting section 31 away from the connecting rod 2. The hand grip 33 is the part that interacts most directly with the user, providing a comfortable and firm gripping area, extending along the extension direction of the connecting rod 2, and one end of the second connecting section 32 is connected to the end of the second connecting section 32 away from the first connecting section 31. The shape and size of the hand grip are designed according to ergonomic principles, and may include anti-slip patterns, soft material wrapping or a curved design that conforms to the contour of the palm to improve the comfort and stability of the grip. By introducing the turning of the second connecting section 32, the hand grip 3 can be presented at an angle that is more in line with the natural posture of the human body, reducing wrist and arm fatigue during long-term use.

[0052] In some embodiments, the disassembly and assembly device further includes: a lighting device 6, which is arranged on the connecting rod 2 and is used for lighting.

[0053] Specifically, Figure 1-Figure 5 As shown, the connecting rod 2 is provided with a lighting device 6, which can be an LED lamp, a fluorescent lamp or a laser lamp, etc. When performing maintenance or disassembly work in a dim or closed space, the lighting device 6 on the connecting rod 2 can directly illuminate the working area, significantly improving visibility, so that maintenance personnel can more clearly see the position of the parts to be disassembled.
