Description

Technical Field

[0001] The invention relates to the technical field of equipment maintenance, and in particular to a pneumatic clamping device for equipment maintenance. Background Art

[0002] With the acceleration of the process of regularization and modernization, weapons and equipment have developed rapidly, the number of equipment has become increasingly large, and the number of models has increased. In recent years, the number and frequency of equipment mobilization have increased significantly compared with the past, and the difficulty of equipment maintenance and support has become increasingly greater, and the maintenance and support tasks have become increasingly heavier.

[0003] When repairing the moving parts of crawler mobile equipment, the following problems often occur: ① Special installation position: The components of the tracked equipment are installed on both sides of the vehicle body, and the distance between the components is relatively small, which is not conducive to disassembly and assembly; the installation height also varies greatly. For example, the outer edge of the road wheel is only 480mm from the ground, while the installation center height of the driving wheel can reach 1020mm; most of the components are installed under the fenders, which is inconvenient to lift with a crane.

[0004] ② Different shapes of parts: The shapes of different parts of the action part of armored equipment vary greatly. Some are round, such as inducers and road wheels; some are curved, such as crank arms and balance elbows; some are toothed, such as driving wheels; some are long cylindrical, such as torsion shafts; some have the center of gravity at the center of the component's geometric shape, such as driving wheels, inducers, and road wheels; some have the center of gravity not at the center of the component's geometric shape, such as side reducers, crank arms, and balance elbows, etc.

[0005] ③ Large weight difference: The weight of the moving parts of different models varies greatly, and the weight of each component of the same model is also different.

[0006] ④ High technical requirements: The fixing bolts of each component of the action part have torque requirements during installation, and there is also the problem of centering each component during installation. Since the components are heavy and the fixing bolts are large, the contradiction between tightening torque and centering is more prominent.

[0007] ⑤ Difficulty in disassembly: The moving parts are in poor condition and difficult to disassemble. During the disassembly process, due to poor sealing, not only a large amount of sand accumulates on the mating surfaces, but also rusts very seriously, especially the disassembly of the torque shaft and the balance elbow.

The supporting seat 4 reserves an installation space for the rotating platform 5, so that the rotating platform 5 can be rotated and adjusted on the supporting seat 4. The rotating platform 5 is a vertically arranged cylindrical structure, and a flat plate for installing a lifting cylinder 6 is arranged above it. The side wall of the rotating platform 5 is symmetrically provided with a gas cylinder 7 and a gas valve box 19, which can cooperate with the gas source to control the gas flow, so as to meet different clamping requirements; The mounting bracket 9 is arranged above the rotating platform 5. The mounting bracket 9 is a door-shaped structure. A rotating shaft for mounting a lifting arm 11 is arranged on the inner wall. A mounting seat 8 is arranged below the mounting bracket 9. The mounting seat 8 is fixedly connected to the rotating platform 5 by bolts. A lifting arm 11 is rotatably mounted on the inner wall of the mounting bracket 9. There are two lifting arms 11, which are designed in an upper and lower parallel manner and can drive the lifting arms 11 to move upward synchronously under the action of the lifting cylinder 6. The rotating platform 5 is provided with a lifting cylinder 6 for driving the lifting arm 11 to move. Both the rotating platform 5 and the lifting arm 11 located below are provided with an articulated mounting seat 8, so that the lifting cylinder 6 can rotate during the lifting process; The lifting bracket 12 is arranged at the end of the lifting arm 11. The lifting arm 11 is rotatably connected to the lifting bracket 12. A first rotating bracket 13 is arranged below the lifting bracket. The lifting bracket 12 is vertically arranged and installed on the lifting arm 11, parallel to the mounting bracket 9, and can always drive the lifting bracket 12 to maintain a vertical state during the rotation of the lifting arm 11, thereby ensuring that the first rotating bracket 13 remains stable during the movement; The second rotating bracket 14 is arranged below the first rotating bracket 13. The second rotating bracket 14 is also an L-shaped structure. The second rotating bracket 14 is rotatably connected to the first rotating bracket 13, so that the second rotating bracket 14 can rotate on the first rotating bracket 13 to meet the needs of subsequent equipment maintenance; The support cylinder 18 is arranged at the bottom of the second rotating bracket 14. The end of the support cylinder 18 is provided with a rotating sleeve 17. The support cylinder 18 is horizontally arranged at the bottom end of the second rotating bracket 14, and the support cylinder 18 can be rotated and adjusted on the second rotating bracket 14 to meet the subsequent maintenance requirements; The vertical plate 27 is arranged at the end of the rotating sleeve 17. The vertical plate 27 is a vertically arranged flat plate, which is welded and fixed to the end of the rotating platform 5, and a reinforcing plate is provided between the vertical plate 27 and the rotating platform 5 to ensure the connection strength and avoid deformation when under pressure. The vertical plate 27 is provided with a disassembly seat 32, which is integrally formed with the vertical plate 27 and serves as the installation base of the clamping seat 16. The clamping seat 16 is installed above the disassembly seat 32. Due to the different structural designs of the wheel bodies of different carriers, the sizes will also be different. In order to improve the adaptability of the device, a replaceable clamping seat 16 is designed, which can be adjusted according to the current carrier, thereby improving the operating capacity. The clamping seat 16 is provided with a positioning groove for placing the component, which can support the component, thereby keeping the state of the component stable; The driving rod 30 is arranged in the rotating sleeve 17, and the end of the driving rod 30 passes through the vertical plate 27. The rotating sleeve 17 is provided with a cylinder for driving the driving rod 30 to move. The end of the driving rod 30 is formed with a thread, and a mold can be added later, so that it can be buckled and installed at the edge of the component to clamp and fix the inner wall of the component, and then the cylinder inside the rotating stand 5 works to drive the component to move outward, remove the component from the carrier, and realize the disassembly and assembly of the component, which solves the problem of difficulty in manual operation due to the narrow space inside the carrier, and significantly reduces the labor intensity of maintenance personnel. At the same time, the cylinder stroke is stable and will not suddenly unload force, ensuring the safety of the component disassembly and assembly process; The positioning cylinder 33 is arranged on the outer wall of the vertical plate 27. A lifting seat 29 is arranged on the top of the positioning cylinder 33. An arm mounting frame is arranged above the lifting seat 29. The arm mounting frame is fixedly mounted on the lifting seat 29, and a plurality of mounting holes are arranged on the top of the arm mounting frame to facilitate the installation of the mold. The mold is mainly used to snap and position the edge of the component on the carrier, so as to maintain the stability of the component. There are two positioning cylinders 33, and a symmetrical structure is adopted. The two ends of the lifting seat 29 are connected to the piston rod of the positioning cylinder 33. When in use, the piston rod of the positioning cylinder 33 can work synchronously to drive the lifting seat 29 to move up, thereby making the arm mounting frame 28 move up together, and the inner wall edge of the component is snapped and fixed by the mold on the arm mounting frame 28, so as to finally realize the clamping of the component, which can facilitate the fixing of the component removed from the carrier, thereby ensuring the stability of the component during the movement of the equipment and avoiding safety accidents caused by falling. Before use, select the corresponding clamping seat 16 for replacement according to the carrier model to be repaired, and install the mold on the driving rod 30. When in use, the operator adjusts the position of the clamping seat 16, rotates the second rotating bracket 14, the first rotating bracket 13 and the rotating platform 5, so that the clamping seat 16 is close to the carrier wheel body, and then the clamping seat 16 is inserted into the bottom edge of the component for preliminary positioning, and then the groove on the driving rod 30 is positioned. After positioning, the mold on the driving rod 30 is connected to the component, and then the cylinder inside the rotating sleeve 17 is controlled to work, so as to move the carrier. The tool wheel body is removed, and then the mold on the driving rod 30 is removed, and the angle of the clamping seat 16 is adjusted so that the component can be accurately inserted into the groove on the clamping seat 16, thereby supporting and fixing the bottom edge of the component. At this time, the positioning cylinder 33 works to drive the lifting seat 29 to move up, so that the support arm mounting frame 28 moves up together. At this time, the mold on the support arm mounting frame 28 will abut against the top of the component to achieve positioning and clamping of the component, ensuring the stability of the component during transportation, and finally moving the removed component to the discharge rack on the side for storage, that is, completing the use process of the entire pneumatic clamping equipment.

[0026] In another embodiment, a locker 25 is provided above the support cylinder 18, and a locking plate 24 corresponding to the position of the locker 25 is provided on the outer wall of the rotating sleeve 17. The locker 25 is fixedly mounted on the top surface of the support cylinder 18, and an electric push rod is provided inside the locker 25, which can make the positioning rod on the side wall of the locker 25 extend outward, and then be inserted into the circular hole of the locking plate 24 at the end of the rotating stage 5, thereby realizing the angle limitation of the rotating sleeve 17, and ensuring that the rotating sleeve 17 always remains stable during the transportation of the carrier wheel body, avoiding the deflection of the rotating sleeve 17 during the transportation process and causing the carrier wheel body to fall off.

[0027] In another embodiment, a limit cylinder 21 is provided at the bottom of the support tube 18, and a clamping block 20 for fixing the locking plate 24 is provided below the limit cylinder 21. In order to further improve the stability of the rotating sleeve 17, a limit cylinder 21 is added. Since the holes on the locking plate 24 are limited, the rotating sleeve 17 may not be inserted when the angle is adjusted. Therefore, it is necessary to use the limit cylinder 21 to cooperate with the clamping block 20 to fix the locking plate 24, so as to ensure the stability of the rotating sleeve 17. The limit cylinder 21 extends outward when the angle of the rotating sleeve 17 is adjusted, so that the clamping block 20 at the bottom leaves the locking plate 24. At this time, the locking plate 24 can rotate freely and the angle of the rotating sleeve 17 can be adjusted. After the adjustment is completed, the limit cylinder 21 is The cylinder 21 automatically resets, so that the clamping block 20 fits the locking plate 24 again, achieving clamping and fixing to prevent the rotating sleeve 17 from deflecting. An adjusting arm 23 is provided on the outer wall of the rotating sleeve 17, and a control button 22 is provided at the end of the adjusting arm 23. There are two adjusting arms 23, and a symmetrical structure is arranged. The control button 22 is provided so that during the angle adjustment process of the rotating sleeve 17, the user needs to hold the two adjusting arms 23 for rotation adjustment. At this time, it is necessary to press the control buttons 22 on the two adjusting arms 23 first, and the limit cylinder 21 will extend, driving the clamping block 20 to be exported, thereby releasing the limitation on the locking plate 24, thereby preventing the rotating sleeve 17 from being accidentally touched by a person during use and causing a sudden deflection of the angle, thereby improving the safety of the equipment.

[0028] In another embodiment, a vertically arranged slide rail 26 is provided on the outer wall of the vertical plate 27, and a guide block corresponding to the position of the slide rail 26 is provided on the outer wall of the lifting seat 29. The slide rail 26 is symmetrically arranged on the vertical plate 27 and can be slidably guided with the guide block, thereby ensuring the stability of the lifting seat 29 during the up and down movement.

[0030] In another embodiment, an operation panel 15 is provided on the outer wall of the second rotating bracket 14, and the operation panel 15 can facilitate users to control the working state of the equipment, thereby reducing the difficulty of operation.

[0031] In another embodiment, reinforcing ribs 2 are provided between the supporting platform 1 and the main supporting frame 3, and the reinforcing ribs 2 can enhance the connection strength between the supporting platform 1 and the main supporting frame 3, thereby enhancing the overall supporting stability of the equipment.

[0032] In another embodiment, a counterweight plate 10 is provided at one end of the lifting arm 11 away from the lifting bracket 12. The design of the counterweight plate 10 can adjust the weight of both ends of the lifting arm 11 on the mounting bracket 9 as much as possible, which facilitates the subsequent support adjustment of the lifting arm 11.

[0033] In another embodiment, a brake disc 34 is provided on the first rotating bracket 13, and a limit seat 35 is provided on the side wall of the lifting bracket 12. The limit seat 35 is provided with a groove for placing the brake disc 34, and the limit seat 35 is provided with a brake cylinder 36 for fixing the brake disc 34.

The same structural design is also reflected in the rotating platform 5 and the supporting seat 4. The damping design is adopted between the first rotating bracket 13 and the second rotating bracket 14, which can meet the angle adjustment requirements between the first rotating bracket 13, the lifting arm 11 and the main support frame 3 during use of the equipment. When not in use, the brake cylinder 36 inside the limit seat 35 works to clamp and fix the brake disc 34, thereby ensuring the stability of the brake disc 34 and preventing rotation.
