Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] An embodiment of this utility model provides a compressor maintenance device, which includes:

[0035] Maintenance Platform 1;

[0036] The support assembly 2, which is disposed on the maintenance platform 1, is used to support the compressor 4 to be maintained; and

[0037] The disassembly assembly 3 is disposed on the maintenance platform 1 and is opposite to the bearing assembly 2 in the first direction. The disassembly assembly 3 includes a movable base 31, a disassembly shaft 32 disposed on the movable base 31, a connecting sleeve 33 sleeved on the disassembly shaft 32, and a plurality of connecting rods 34 disposed on the connecting sleeve 33. The plurality of connecting rods 34 are distributed along the circumference of the connecting sleeve 33.

[0038] One end of the connecting rod 34 is configured as a hook-shaped structure that can hold the component to be disassembled of the compressor 4, and the other end is hinged to the connecting sleeve 33. The movable seat 31 is configured to move along the first direction so as to pull the component to be disassembled through the connecting rod 34.

[0039] Specifically, the maintenance device of this utility model mainly solves the problem of difficulty in disassembling certain components of the air compressor 4 during the disassembly process. For example, the disassembly of the motor or other components involving the rotating shaft of the compressor 4, particularly the parts that mate with the rotating shaft, is quite difficult. Figure 1 As shown, the maintenance platform 1 of the maintenance device serves as the structural foundation, on which a support component 2 and a disassembly component 3 are mounted. The support component 2 is used to hold the compressor 4 to be maintained (the compressor 4 to be maintained can be the entire compressor 4 or a component within the compressor 4). The disassembly component 3 is positioned opposite the support component 2 and is used to disassemble the components of the compressor 4 to be disassembled.

[0040] The disassembly assembly 3 first includes a movable seat 31 that can move in a first direction, moving closer to or further away from the support assembly 2. A disassembly shaft 32 is provided on the movable seat 31, parallel to the first direction. An annular connecting sleeve 33 is fitted onto the disassembly shaft 32, and the connecting sleeve 33 is used to assemble the connecting rod 34, as shown in the attached diagram. Figures 1 to 3 As shown, one end of the connecting rod 34 is hinged to the connecting sleeve 33, and the other end is bent in the radial direction of the disassembly shaft 32 to form a hook-shaped structure. The hook-shaped structures of multiple connecting rods 34 together present a gripper that can hold the corresponding parts.

[0041] In use, the compressor 4 or a component of the compressor 4 to be repaired is fixed to the bearing assembly 2, and the moving seat 31 is moved along the first direction to be close to the object to be repaired. According to the size of the parts to be disassembled on the object to be repaired, the corresponding connecting rod 34 is rotated so that one end of the hook-shaped structure of the connecting rod 34 opens to be able to catch the edge of the parts to be disassembled, and one end of the hook-shaped structure of each connecting rod 34 is caught on the edge of the parts to be disassembled. Then the moving seat 31 is moved in the opposite direction along the first direction to pull the parts to be disassembled and remove them from the object to be repaired.

[0042] It should be noted that the maintenance platform 1 is equipped with a drive component (which can be a hydraulic cylinder or a pneumatic cylinder) that cooperates with the movable seat 31 to drive the movable seat 31 to move forward and backward in the first direction. In addition, when disassembling components on the motor shaft or other shafts of the compressor 4, the corresponding shaft is made to be coaxial with the disassembly shaft 32 and the ends of the shafts abut against each other, which can improve the stability during disassembly.

[0043] This invention utilizes the cooperation of the supporting component 2 and the disassembly component 3 to automatically disassemble corresponding parts on the object to be repaired, replacing manual labor and thus improving safety and work efficiency. Furthermore, the adjustable connecting rod 34 of the disassembly component 3 can accommodate parts of different sizes or shapes on the object to be repaired, thereby improving the versatility of the device.

[0044] Preferably, the outer circumferential surface of the disassembly shaft 32 is threaded, and the connecting sleeve 33 is threadedly engaged with the disassembly shaft 32.

[0045] Specifically, as shown in the attached document Figures 1 to 3 As shown, at least a partial area of ​​the outer circumferential surface of the disassembly shaft 32 has a threaded structure, so the connecting sleeve 33 and the disassembly shaft 32 can be threaded together. This allows for fine adjustment of the position of the connecting sleeve 33, and consequently, fine adjustment of the position of the connecting rod 34, to meet the requirement of a small distance between the connecting rod 34 and the disassembly components.

[0046] In one embodiment, the connecting rod 34 is hinged to one end of the connecting sleeve 33 and connected to a rod-shaped limiting part 35. The limiting part 35 is bent relative to the connecting rod 34, and the intersection of the limiting part 35 and the connecting rod 34 is hinged to the connecting sleeve 33. The disassembly shaft 32 is fitted with a limiting disc 36 adjacent to the connecting sleeve 33. The limiting disc 36 is configured to abut against the end of the limiting part 35.

[0047] Specifically, as shown in the attached document Figures 1 to 3 As shown, the end of the connecting rod 34 is connected to a rod-shaped limiting part 35. The limiting part 35 is bent outward in the radial direction relative to the connecting rod 34 along the disassembly shaft 32, so that the end of the connecting rod 34 and the limiting part 35 form a V-shape. A limiting plate 36 is also provided on the disassembly shaft 32 on one side of the limiting part 35. The limiting plate 36 is used to prevent the connecting rod 34 from rotating incorrectly when it comes into contact with the limiting part 35, which would cause one end of the hook-shaped structure to open.

[0048] Specifically, when one end of the hook-shaped structure of the connecting rod 34 is fastened to the component to be disassembled, that end of the hook-shaped structure of the connecting rod 34 (due to the obstruction of the component to be disassembled) cannot retract further inward, but can open outward, thus posing a risk of detaching from the component to be disassembled. Due to the presence of the limiting part 35 and the intersection of the limiting part 35 and the connecting rod 34 serving as the hinge point with the connecting sleeve 33, the limiting part 35 and the connecting rod 34 are essentially equivalent to the two ends of a lever. When one end of the hook-shaped structure of the connecting rod 34 opens outward, the limiting part 35 retracts inward, causing the end of the limiting part 35 to move axially away from the connecting rod 34 in the direction of the disassembly shaft 32. Therefore, a limiting plate 36 is provided on one side of the limiting part 35. When one end of the hook-shaped structure of the connecting rod 34 is fastened to the part to be disassembled, the limiting plate 36 abuts against the end of the limiting part 35. This can prevent the end of the limiting part 35 from moving away from the connecting rod 34 in the axial direction of the disassembly shaft 32, thereby preventing one end of the hook-shaped structure of the connecting rod 34 from opening outward and detaching from the part to be disassembled.

[0049] Preferably, the limiting disc 36 is threadedly engaged with the disassembly shaft 32, thereby allowing the position of the limiting disc 36 to be flexibly adjusted as needed to adjust the engagement between the limiting disc 36 and the limiting part 35.

[0050] In one embodiment, the disassembly assembly 3 further includes a first driving member 37 disposed on the movable base 31, the driving end of the first driving member 37 being connected to the disassembly shaft 32 to drive the disassembly shaft 32 to extend and retract along a first direction.

[0051] Specifically, as shown in the attached document Figure 5 As shown, the first driving component 37 is mounted on the movable seat, and can be a pneumatic cylinder or a hydraulic cylinder. The first driving component 37 is used to mount the disassembly shaft 32 and can drive the disassembly shaft 32 to move along the first direction. Thus, when disassembling the parts on the object to be repaired, the disassembly shaft 32 can be driven to move to hold the main body of the object to be repaired, ensuring the stability of the disassembly process.

[0052] In one embodiment, the movable base 31 is provided with an elongated opening 311 extending perpendicular to the surface of the maintenance platform 1. The driving end of the first driving member 37 passes through the elongated opening 311 and is connected to the disassembly shaft 32. The first driving member 37 is fixed to the elongated opening 311 by a connecting plate 38. The movable base 31 is provided with elongated holes 312 around the elongated opening 311, which are aligned with the extending direction of the elongated opening 311. The connecting plate 38 is fixedly connected to the movable base 31 by a threaded part passing through the elongated hole 312.

[0053] Specifically, as shown in the attached document Figure 4 and Figure 5As shown, the first driving member 37 fits into the elongated opening 311 of the movable base 31, thereby allowing its relative position to be adjusted in a direction perpendicular to the surface of the maintenance platform 1. This adjustment allows for the measurement of the installation height of the first driving member 37 to accommodate objects of different heights requiring maintenance. Correspondingly, the first driving member 37 is fixed to the movable base 31 via a connecting plate 38. Therefore, the installation position of the connecting plate 38 relative to the movable base 31 also needs to be adjustable. This is achieved by providing an elongated hole 312 near the elongated opening 311 to allow the connecting plate 38 to adjust its position along with the first driving member 37 in a direction perpendicular to the surface of the maintenance platform 1.

[0054] In one embodiment, the maintenance platform 1 is provided with a track 11 extending in a first direction, the movable seat 31 is engaged with the track 11, and a second drive member is provided at the track 11 that engages with the movable seat 31.

[0055] Specifically, as shown in the attached document Figure 1 and Figure 5 As shown, the movable seat 31 is movable in the first direction via the track 11. The maintenance platform 1 is further provided with a second driving member (not shown in the figure) for driving the movable seat 31 at the track 11. The second driving member can be a cylinder or a hydraulic cylinder.

[0056] In one embodiment, the track 11 includes two parallel guide rails that are higher than the platform of the maintenance platform 1. The platform of the maintenance platform 1 has an assembly port 12 located between the two guide rails. The bottom of the movable seat 31 is provided with a counterweight 313 that fits into the assembly port 12.

[0057] Specifically, as shown in the attached document Figure 4 and Figure 5 As shown, the portion of the platform surface of the maintenance platform 1 located between the two guide rails is configured as an assembly port 12, used to mate with the counterweight 313 at the bottom of the movable seat 31. At least a portion of the counterweight 313 is located below the platform surface of the maintenance platform 1. The purpose of this design is that, since the movable seat 31 needs to withstand a large force during the movement and disassembly of parts, in order to improve the stability of the movable seat 31, it is necessary to increase the self-weight of the movable seat 31 and lower its overall center of gravity. This is achieved through the assembly port 12 and the counterweight 313.

[0058] In one embodiment, the support component 2 includes a support base 21 and a support plate 22 disposed on the support base 21. The support base 21 is fixed to the maintenance platform 1, and the central support base 21 of the support plate 22 is rotatably engaged.

[0059] Optionally, the area of ​​the bearing plate 22 is larger than that of the bearing seat 21, and the four corners of the bearing plate 22 are respectively provided with leveling bolts 221 that can abut against the surface of the maintenance platform 1.

[0060] Specifically, as shown in the attached diagram. Figure 2 As shown, the support base 21 in the support assembly 2 is fixed on the maintenance platform 1. A support plate 22 is provided on the support base 21, and the support plate 22 is used to place the corresponding object to be maintained. The center of the support plate 22 is rotatably engaged with the support base 21. Specifically, the support plate 22 may have a rotating shaft at its center, which is inserted into the support base 21. This allows the support plate 22 to rotate relative to the support base 21, and the orientation of the object to be maintained on the support plate 22 can be adjusted as needed to meet different requirements. Furthermore, the leveling bolt 221 can be used to adjust the levelness of the support plate 22, and can also adjust the height of the support plate 22 relative to the maintenance platform 1 within a certain range, thereby fine-tuning the installation height of the object to be maintained.
