Description

Technical Field

[0001] The present invention relates to a disassembly and assembly tool, and in particular to a disassembly and assembly mechanism and operation method for a gearbox cover of a centrifugal air compressor. Background Art

[0002] A centrifugal air compressor uses an impeller to drive gas to rotate at a high speed, causing the gas to generate centrifugal force. The flow rate and pressure of the gas are increased after passing through the impeller, thereby continuously producing compressed air.

[0003] The gearbox is an important component of a centrifugal air compressor. Generally, it is large in volume and heavy in mass, and it contains high-precision components inside. After long-term operation, the gearbox often needs maintenance, and the box cover needs to be removed during maintenance.

[0004] Currently, methods for removing box cover-like workpieces from equipment generally include manual lifting and hanging with a crane. These methods are not only time-consuming and laborious, but also easily damage precision devices such as gears and bearings by bumping into them. Summary of the Invention

[0005] To solve the technical problems in the background art, the present invention proposes a disassembly and assembly mechanism and operation method for a gearbox cover of a centrifugal air compressor.

[0006] A disassembly and assembly mechanism for a gearbox cover of a centrifugal air compressor includes: a base frame, a working frame, and an actuator. The working frame includes support columns and a plurality of mounting beams slidably arranged on the support columns. The support columns are vertically arranged on the base frame. The plurality of mounting beams are parallel to each other and are arranged at intervals in the length direction of the support columns. At least one set of actuators is provided on each mounting beam. The actuator includes a support, a shaft rod, and a handwheel. The support can slide along the length direction of the mounting beam. The shaft rod vertically penetrates the support and is movably connected to the support. The handwheel is arranged at one end of the shaft rod to drive the axial movement of the shaft rod.

[0007] As a further optimization of the above solution, the support column includes a first mounting section and a second mounting section. The first mounting section is movably mounted on the base frame and can be adjusted in height. The second mounting section is rotatably connected to the first mounting section, and an adjustment handle is provided on the first mounting section to adjust the deflection angle of the second mounting section on the first mounting section. The mounting beams are all arranged on the second mounting section.

[0008] As a further optimization of the above solution, the axial direction of the shaft rod always remains perpendicular to the mounting beam and the second mounting section.

[0009] As a further optimization of the above solution, the shaft rod has a first threaded section and a second threaded section arranged at intervals along its axial direction. The second threaded section is threadedly mounted on the support, and the handwheel is arranged at the end of the second threaded section.

[0010] As a further optimization of the above solution, it also includes a nut that is detachably assembled on the actuator, and the nut can be threadably matched with the first thread segment.

[0011] As a further optimization of the above solution, universal wheels are installed at the bottom of the basic frame, and a counterweight block is arranged on the basic frame.

[0012] An operating method for disassembling and assembling a gearbox cover of a centrifugal air compressor:

[0013] S1. Select the symmetrical or diagonal screws on the gearbox cover to remove them;

[0014] S2, lifting the first installation section to complete the rough adjustment of the vertical height of the work frame;

[0015] S3. Turn the adjustment handle to adjust the angle of the second installation section until the shaft of the actuator is perpendicular to the gear box cover;

[0016] S4, adjusting the position of a part of the mounting beam on the support column and the position of the actuator on the mounting beam until the shaft of the actuator is accurately inserted into the screw hole after the screw is removed;

[0017] S5, lock the position of the actuator, and turn the handwheel at the end of the shaft so that the shaft completely enters the screw hole;

[0018] S6. Adjust the position of the remaining mounting beam on the support column and the position of the actuator on the mounting beam until the shaft of the actuator can be accurately inserted into the ejection hole on the gear box cover;

[0019] S7, lock the position of the actuator, and rotate the handwheel at the end of the shaft rod to make the shaft rod completely enter the ejection hole, and lift the box cover to be disassembled to separate it from the equipment body;

[0020] S8, after the box cover is separated from the equipment body by an appropriate distance, continue to screw the shaft in the screw hole until the first threaded section on the shaft passes through the box cover, and assemble the nut on the first threaded section of the shaft;

[0021] S9. Remove the disassembly mechanism.

[0022] 1. The disassembly and assembly mechanism and operation method of the gear box cover of a centrifugal air compressor proposed in the present invention can make the disassembly and assembly work more precise. A plurality of actuators with freely adjustable positions respectively play the role of guiding and ejecting, so that the gear box cover workpiece can be smoothly exported, ensuring that the safety of the core components is not affected while overcoming the disadvantages of time-consuming and labor-intensive manual lifting.

[0023] 2. The present invention proposes a centrifugal air compressor gear box cover disassembly and assembly mechanism and operation method. By adjusting the support column, the height and angle of the actuator can be adjusted, so that it has good adaptability to the disassembly of the box cover of the gear box with different sizes and structures.

[0030] A disassembly and assembly mechanism for a gearbox cover of a centrifugal air compressor proposed in this embodiment, as Figures 1 to 3 shown, includes: a base frame 1, a working frame 2, and an actuator 3.

[0031] The bottom of the base frame 1 is provided with universal wheels 6 for easy movement.

[0032] The working frame 2 includes support columns 21 and a plurality of mounting beams 22 slidably arranged on the support columns 21. The support columns 21 are vertically arranged on the base frame 1. More specifically, the support columns 21 include a first mounting section 211 and a second mounting section 212. The first mounting section 211 is movably mounted on the base frame 1 and the first mounting section 211 can be adjusted in height to roughly adjust the vertical height of the working frame 2. The second mounting section 212 is rotatably connected to the first mounting section 211, and an adjustment handle 4 is provided on the first mounting section 211 to adjust the deflection angle of the second mounting section 212 on the first mounting section 211.

[0033] The adjustment handle 4 can be locked so that the second mounting section 212 can remain stable after rotating at any angle.

[0034] The plurality of mounting beams 22 are parallel to each other and are arranged at intervals in the length direction of the support columns 21. Specifically, the mounting beams 22 are arranged on the second mounting section 212 and are perpendicular to the second mounting section 212.

[0035] Preferably, the number of mounting beams 22 is three.

[0036] At least one set of actuators 3 is provided on each mounting beam 22. The actuator 3 includes a support 31, a shaft rod 32, and a handwheel 33. The support 31 is slidable along the length direction of the mounting beam 22. External threads are provided at both ends of the shaft rod 32, so that a first thread section 321 and a second thread section 322 are arranged at intervals in the axial direction thereof. The second thread section 322 vertically penetrates the support 31 and is screwed to the support 31. More specifically, the axial direction of the shaft rod 32 always remains perpendicular to the mounting beam 22 and the second mounting section 212. The handwheel 33 is arranged at the end of the second thread section 322. By screwing the handwheel 33, the axial movement of the shaft rod 32 can be driven.

[0037] Preferably, two sets of actuators 3 are provided on each mounting beam 22. When the disassembly and assembly mechanism works, some actuators 3 serve as guiding parts for inserting into the gearbox cover and supporting it, and some actuators 3 serve as ejecting parts for separating the gearbox cover from the equipment main body. Moreover, according to the hole position arrangement on the gearbox cover, the actuators 3 serving as guiding parts or ejecting parts can be mutually converted.

[0038] A nut 5 is also detachably assembled on the actuator 3, and the nut 5 can be in threaded cooperation with the first thread section 321.

[0039] To prevent the foundation frame 1 from tipping over after the workbench 2 disassembles the box cover, it is extremely necessary to set a counterweight 7 on the foundation frame 1.

[0040] For the specific usage method of the disassembly and assembly mechanism of the gearbox cover of a centrifugal air compressor proposed in this embodiment, refer to Figure 4 、 Figure 5 , and the specific process is as follows:

[0041] First, select the symmetrical or diagonal screws on the gear box cover to remove them, and then lift the first mounting section 211 to complete the rough adjustment of the vertical height of the workbench 2, adjust the position of part of the mounting beam 22 on the support column 21 and the position of the actuator 3 on the mounting beam 22, until the shaft 32 of the actuator 3 is accurately inserted into the screw hole after the screw is removed, that is, use this part of the actuator 3 as a guide, lock the position of the actuator 3, and turn the handwheel 33 at the end of the shaft 32 so that the shaft 32 completely enters the screw hole, then adjust the position of the remaining mounting beam 22 on the support column 21 and the mounting beam 2 2, until the shaft 32 of the actuator 3 can be accurately inserted into the ejection hole on the gear box cover, that is, the actuator 3 of this part is used as the ejection part, the position of the actuator 3 is locked, and the handwheel 33 at the end of the shaft 32 is turned to make the shaft 32 completely enter the ejection hole, and the box cover to be disassembled is lifted to separate it from the equipment body. After the box cover is separated from the equipment body by an appropriate distance, the shaft 32 in the screw hole is continued to be screwed until the first threaded section 321 on the shaft 32 passes through the box cover, and the nut 5 is assembled on the first threaded section 321 of the shaft 32 to prevent the box cover from slipping, and finally the disassembly mechanism is removed.

[0042] contrast Figure 4 and Figure 6 When the box cover workpiece to be disassembled is perpendicular to the horizontal plane, there is no need to adjust the angle of the second installation section 202. When the box cover workpiece to be disassembled has a certain angle with the vertical plane, the angle of the second installation section 202 needs to be adjusted by adjusting the handle 4.

[0043] The disassembly and assembly mechanism of the gear box cover of a centrifugal air compressor proposed in this embodiment can make the disassembly and assembly work more precise, and overcome the shortcomings of time-consuming and labor-intensive manual lifting, while effectively achieving the purpose of ensuring the safety of precision parts.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
