Description

Technical Field

[0001] This utility model relates to the technical field of reciprocating compressor maintenance equipment, specifically a device for quick disassembly and assembly of the pressure body of a reciprocating compressor. Background Technology

[0002] Reciprocating compressors are widely used in industrial production. A reciprocating compressor mainly consists of the following core components: 1. Power transmission system: This includes the crankshaft, connecting rod, and crosshead, which converts rotary motion into reciprocating motion of the piston. The crosshead slide is usually designed to be open to facilitate the installation and maintenance of the main bearing and connecting rod.

[0003] 2. Compression unit: also known as pressure body, which consists of cylinder, piston, and valve group (intake valve / exhaust valve). The piston compresses gas through reciprocating motion.

[0004] 3. Auxiliary systems: such as lubricating oil pumps, safety accessories, and packing seals (piston rings, guide rings, etc.) to reduce friction and seal gas.

[0005] The pressure body of a reciprocating compressor is large and heavy. After the piston rod and crosshead are separated, the traditional method of removing the pressure body from the piston rod and taking it out of the middle body is time-consuming and laborious, which seriously affects the efficiency of equipment maintenance and the convenience of operation and maintenance. An efficient auxiliary disassembly and assembly device is needed to improve this situation. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art by proposing a quick disassembly and assembly device for the pressure body of a reciprocating compressor, thus solving the problem of the pressure body being difficult to disassemble and assemble.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: A quick assembly / disassembly device for a reciprocating compressor pressure body includes a support base, a vertical adjustment bolt lifting rod, a trolley track, a trolley, and a bubble level. Support bases are connected to both sides of the fixed base of the reciprocating compressor. Vertical adjustment bolt lifting rods are threaded onto the support bases. The tops of the two vertical adjustment bolt lifting rods are connected to the same trolley track, which passes through the space between the pressure body and the fixed base. The trolley is slidably connected to the trolley track, and the trolley contacts the bottom of the pressure body, thus supporting the pressure body. A bubble level is installed on the upper surface of one side of the trolley track.

[0008] Furthermore, the support base is provided with a threaded hole that runs vertically through the top and bottom. The top of the vertical adjustment bolt lifting rod passes through the threaded hole, and the vertical adjustment bolt lifting rod is connected to the support base by a locking nut.

[0009] Furthermore, the trolley track can pass through the central viewing window set on the reciprocating compressor housing and be connected to the mounting hole of the central viewing window by bolts. Rolling bearings are installed inside the trolley track.

[0010] Furthermore, the side of the trolley track is equipped with a scale.

[0011] Furthermore, adjusting bolts are fixedly connected to both sides of the bottom of the trolley track. The top of the vertical adjusting bolt lifting rod is provided with a transverse threaded rod that matches the adjusting bolt. The adjusting bolt is connected to the transverse threaded rod at the top of the vertical adjusting bolt lifting rod. A horizontal fine-tuning screw is connected to one side of the adjusting bolt.

[0012] Furthermore, a handle is connected to the trolley.

[0013] Furthermore, after the pressure body is placed on the trolley, anti-slip blocks are placed on both sides of the bottom of the pressure body.

[0014] The beneficial effects of this utility model compared to the prior art are as follows: 1. Improved efficiency: No need to repeatedly adjust the center of the pressure body, preventing the risk of damaging the surface of the zigzag slide, shortening maintenance time, and making disassembly convenient and quick. Compared with traditional manual disassembly and assembly, it can shorten the disassembly and assembly time of a single compressor pressure body by more than 60%, greatly improving maintenance efficiency.

[0015] 2. Precision assurance: By using a level and adjusting screws, the coaxiality error between the pressure body and the piston rod is controlled within 0.1mm, ensuring the stability of equipment operation.

[0016] 3. High versatility: By replacing the adapter support structure, it can be used for disassembling and assembling pressure bodies of different models of reciprocating compressors, with a wide range of applications; the connecting components are adjustable to adapt to different models and sizes of reciprocating compressors, with a wide range of applications.

[0017] 4. High safety: Reduces manual handling and lifting operations, lowers labor intensity and safety risks, and improves the safety of operation and maintenance. Attached Figure Description

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0020] See Figure 1 The image shows a side view of the internal pressure body of an existing reciprocating compressor. Below the pressure body 1 is a fixed base 2 inside the compressor. A piston rod 3 passes through the center of the pressure body 1 and connects to a crosshead 4. The existing disassembly and assembly process involves separating the piston rod 3 from the crosshead 4, removing the pressure body 1 from the piston rod 3, and then manually or using a lifting device to remove the pressure body 1. This embodiment proposes a quick disassembly and assembly device for the pressure body of a reciprocating compressor, which is faster, less labor-intensive, and allows for more precise reinstallation of the pressure body 1.

[0021] See Figure 2 and Figure 3 A quick assembly and disassembly device for the pressure body of a reciprocating compressor includes a support base 5, a vertical adjustment bolt lifting rod 6, a trolley track 7, a trolley 8, a bubble level 9, and a horizontal fine-tuning mechanism. Support seats 5 are symmetrically connected to the connecting holes on both sides of the fixed seat 2 via bolts and screws. Each support seat 5 has a through-hole threaded hole. The top of the vertical adjustment bolt lifting rod 6 passes through the threaded hole and is connected to the support seat 5 via a locking nut 10. The tops of the two vertical adjustment bolt lifting rods 6 are connected to the same trolley track 7, which is positioned within the space between the pressure body 1 and the fixed seat 2. The trolley 8 is slidably connected to the trolley track 7. By adjusting the vertical adjustment bolt lifting rods 6, the height of the trolley track 7 and the trolley 8 is adjusted, bringing the trolley 8 into contact with the bottom of the pressure body 1, thus supporting the pressure body 1. Four rolling bearing wheels are installed at the bottom of the trolley 8 to ensure stable movement and positioning.

[0022] The trolley track 7 is made of high-strength alloy material with a wear-resistant surface treatment and has an overall U-shaped structure. The trolley track 7 can pass through the central body viewing window set on the reciprocating compressor housing and is connected to the central body viewing window mounting hole by bolts, which is convenient for disassembly and assembly. Rolling bearings are set inside to reduce the frictional resistance of the pressure body movement.

[0023] A bubble level 9 is installed on the upper surface of one side of the trolley track 7. The bubble level 9 is a high-precision bubble level (bidirectional) to monitor the levelness of the pressure body 1. The levelness of the trolley track 7 is adjusted by the bubble level 9. A scale 11 is installed on the side of the trolley track 7 to mark the position of the pressure body 1 before removal, to assist in recording and reproducing the position, to ensure the consistency of disassembly and assembly, and to facilitate accurate installation.

[0024] To adjust the horizontal position of the trolley track 7, adjusting bolts 12 are fixedly connected to both sides of the bottom of the trolley track 7. The top of the vertical adjusting bolt lifting rod 6 is provided with a transverse threaded rod that matches the adjusting bolt 12. The adjusting bolt 12 is connected to the transverse threaded rod at the top of the vertical adjusting bolt lifting rod 6. A horizontal fine-tuning screw 13 is connected to one side of the adjusting bolt 12. By rotating the horizontal fine-tuning screw 13, the adjusting bolt 12 is moved left and right in the horizontal direction, thereby allowing for fine-tuning of the horizontal position of the trolley track 7.

[0025] To facilitate the movement of the trolley 8, a trolley handle 14 is connected to the trolley 8, which allows the trolley 8 to move easily on the trolley track 7.

[0026] After the pressure body 1 is placed on the trolley 8, anti-slip blocks 15 are placed on the left and right sides of the bottom of the pressure body 1 to prevent the pressure body 1 from rolling on the trolley 8. The anti-slip blocks 15 are triangular anti-slip blocks with a non-slip rubber layer on the surface.

[0027] The method of using the quick disassembly and assembly device for the pressure body of a reciprocating compressor proposed in this embodiment is as follows: 1) Method for disassembling pressure body 1: In use, the support base 5 is fixed to both sides of the compressor's fixed base 2 by bolts, screws or lock nuts. Then, the vertical adjustment bolt lifting rod 6 is connected to the support base 5. The trolley track 7 is installed on the vertical adjustment bolt lifting rod 6. The trolley track 7 is adjusted to a roughly horizontal position by adjusting the vertical adjustment bolt lifting rod 6 on both sides. After the pressure body 1 is disengaged from the piston rod 3 and crosshead 4, the trolley 8 is pushed under the pressure body 1 by the trolley handle 14. Once again, adjust the vertical adjustment bolt lifting rod 6 to align the trolley track 7 with the pressure body 1 by observing the levelness of the high-precision bubble level 9. Then, use the horizontal fine-tuning screw 13 to ensure the trolley 8 is perpendicular to the piston rod 3, guaranteeing accuracy. Secure the vertical adjustment bolt lifting rod 6 with the lock nut 10, and then place the anti-slip blocks 15 on both sides of the pressure body 1 (to prevent the pressure body from rolling). Record the data on the scale 11 for accurate positioning during reassembly. Finally, use the trolley handle 14 to move the pressure body 1 out of the trolley 8 to the maintenance area.

[0028] 2) Reinstallation method: Place the pressure body 1 on the trolley 8 and fix it with the anti-slip block 15. Use the trolley handle 14 to move the pressure body 1 to the installation position by observing the scale 11. After the piston rod 3 and the pressure body 1 are engaged, remove the trolley 8 and simultaneously remove the auxiliary device for quick disassembly and assembly of the reciprocating compressor pressure body.
