Description

Technical Field

[0001] This application relates to the field of compressor repair equipment technology, and in particular to a mobile device for compressor repair. Background Technology

[0002] Compressors play a crucial role in industrial production and numerous applications. However, after prolonged use, compressors may experience various malfunctions, requiring maintenance. Compressors are often large and heavy, making traditional maintenance methods extremely inconvenient when moving them to the repair site or between different workstations within a repair shop. This often relies on manual handling with simple trolleys and other tools, which is not only labor-intensive but also prone to causing secondary damage due to improper operation. Furthermore, maintaining a stable compressor position during movement is difficult, affecting the accuracy and efficiency of subsequent repairs. Therefore, a mobile device for compressor maintenance is proposed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a mobile device for compressor maintenance, so as to solve the problems of inconvenient movement, easy secondary damage, and difficulty in ensuring stable movement during the existing compressor maintenance process.

[0004] The mobile device for compressor maintenance provided in this application adopts the following technical solution:

[0005] A mobile device for compressor maintenance includes a base frame and a handle fixedly connected to the outer wall of the base frame. Two uprights are symmetrically welded to the outer wall of the middle section of the base frame. Lifting plates are installed on the outer walls of the two uprights. Two bearing plates are welded to the outer walls of the lifting plates. Telescopic plates are slidably connected to the inner walls of the bearing plates. Telescopic mechanisms are installed on the outer walls of the bearing plates.

[0006] The outer wall of the upright is equipped with a lifting mechanism, which includes a lead screw, a screw block and a stepper motor. The two ends of the lead screw are rotatably connected to the middle section of the outer wall of the base frame and the upright. The screw block is threadedly connected to the outer wall of the lead screw and fixedly connected to the middle section of the outer wall of the lifting plate. The stepper motor is fixedly connected to the top middle section of the outer wall of the upright, and its output shaft end passes through the upright and is fixedly connected to the top of the lead screw.

[0007] The telescopic mechanism includes two fixed plates fixedly connected to the bottom outer wall of the support plate. The outer walls of the two fixed plates are rotatably connected to sprockets. The outer walls of the two sprockets are meshed with a chain. One end of the two telescopic plates located inside the support plate is fixedly connected to a connecting plate. A connector is fixedly connected to the bottom middle section of the outer wall of the connecting plate. The end of the connector away from the connecting plate is fixedly connected to the lower upper surface of the chain. A servo motor is fixedly installed on the outer wall of one of the fixed plates on the side away from the sprocket. The end of the output shaft of the servo motor passes through the sprocket and is fixedly connected to the axis of the fixed plate.

[0008] Limiting components are installed at the ends of both telescopic plates. Each limiting component includes a baffle that is rotatably connected to the end of the telescopic plate via a rotating shaft. A limiting post is fixedly connected to the top outer wall of the bearing plate, and the baffle corresponds to the limiting post.

[0009] Preferably, the limiting component further includes a secondary gear, a primary gear, and a self-locking motor. The secondary gear is fixedly connected to the outer wall of the middle section of the rotating shaft, while the primary gear is rotatably connected to the inner wall of the end of the telescopic plate via a transmission shaft. The primary gear and the secondary gear mesh with each other.

[0010] Preferably, the self-locking motor is installed on one side of the outer wall of the telescopic plate, and the end of its output shaft passes through the base frame and is fixedly connected to one end of the transmission shaft.

[0011] Preferably, the inner walls of both uprights are slidably connected to sliders, and the two sliders are respectively fixedly connected to the outer walls of the lifting plate near both ends.

[0012] Preferably, the bottom outer wall of the base frame is equipped with a plurality of casters, which are evenly distributed at the four corner edges of the base frame.

[0013] Preferably, the outer wall of the two supporting plates on opposite sides is provided with a sliding groove, and the connecting plate is slidably connected to the two sliding grooves.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. Through the coordinated operation of the lifting mechanism and the telescopic mechanism, the lifting mechanism drives the lifting plate to lower the carrying plate and the telescopic plate until the carrying plate is below the compressor. Then, the telescopic mechanism drives the telescopic plate to extend, inserting it under the compressor. The lifting mechanism then drives the telescopic plate to rise, thereby lifting the compressor and realizing the automatic handling function. At this time, multiple casters at the bottom of the base frame allow the entire mobile device to turn and move flexibly, facilitating free movement in spaces such as maintenance workshops and easily transferring the compressor to different work positions. Compared with existing technologies, it saves time and effort in manual handling and greatly improves the efficiency of compressor transfer during maintenance.

[0016] 2. With the setting of the limiting component, when the two telescopic plates extend below the compressor and the compressor is directly above the telescopic plates, the limiting component drives the baffle to rotate and become perpendicular to the telescopic plates. At this time, the telescopic plate is driven to retract again through the telescopic mechanism. The telescopic plate then drives the baffle to cooperate with the limiting post to limit and fix the press machine, ensuring that the compressor is always in a stable state during the movement. This helps to carry out subsequent maintenance work accurately and improve the quality of maintenance. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a mobile device for compressor maintenance. (Refer to...) Figure 1-5 A mobile device for compressor maintenance includes a base frame 1 and a handle 3 fixedly connected to the outer wall of the base frame 1. Two uprights 2 are symmetrically welded to the outer wall of the middle section of the base frame 1. Lifting plates 5 are installed on the outer walls of the two uprights 2. Two bearing plates 6 are welded to the outer walls of the lifting plates 5. Telescopic plates 7 are slidably connected to the inner walls of the bearing plates 6. Telescopic mechanisms are installed on the outer walls of the bearing plates 6.

[0025] A lifting mechanism is installed on the outer wall of the upright frame 2. The lifting mechanism includes a lead screw 9, a screw block 10 and a stepper motor 11. The two ends of the lead screw 9 are rotatably connected to the middle section of the outer wall of the base frame 1 and the upright frame 2. The screw block 10 is threadedly connected to the outer wall of the lead screw 9 and fixedly connected to the middle section of the outer wall of the lifting plate 5. The stepper motor 11 is fixedly connected to the top middle section of the outer wall of the upright frame 2, and its output shaft end passes through the upright frame 2 and is fixedly connected to the top of the lead screw 9.

[0026] When the stepper motor 11 starts, its output shaft drives the lead screw 9 to rotate. The lead screw 9 then rotates on the inner surface of the screw block 10, thereby driving the screw block 10 to move up and down. When the screw block 10 moves up and down, it drives the lifting plate 5 to rise and fall.

[0027] The telescopic mechanism includes two fixed plates 13 fixedly connected to the bottom outer wall of the support plate 6. The outer walls of the two fixed plates 13 are rotatably connected to sprockets 14. The outer walls of the two sprockets 14 are meshed with a chain 15. The two telescopic plates 7 located inside the support plate 6 are fixedly connected to a connecting plate 18. The bottom middle section of the outer wall of the connecting plate 18 is fixedly connected to a connector 19. The end of the connector 19 away from the connecting plate 18 is fixedly connected to the lower upper surface of the chain 15. A servo motor 16 is fixedly installed on the outer wall of one of the fixed plates 13 away from the sprocket 14. The output shaft of the servo motor 16 passes through the sprocket 14 and is fixedly connected to the axis of the fixed plate 13.

[0028] When the servo motor 16 starts, the output shaft of the servo motor 16 will drive a sprocket 14 to rotate. The two sprockets 14 are synchronously rotated through the chain 15. At this time, the chain 15 rotates around the two sprockets 14, and the connector 19 fixed on the upper surface below the chain 15 is driven to move by the chain 15. The connector 19 drives the connecting plate 18 to slide back and forth. The connecting plate 18 will slide on the inner wall of the two slide grooves 17, and its two ends synchronously drive the two telescopic plates 7 to extend and retract inside the bearing plate 6.

[0029] Limiting components are installed at the ends of both telescopic plates 7. The limiting components include baffles 21 rotatably connected to the ends of the telescopic plates 7 via a rotating shaft 20. Limiting posts 8 are fixedly connected to the top outer wall of the bearing plate 6. The baffles 21 and the limiting posts 8 correspond to each other. The limiting components also include a secondary gear 22, a main gear 24 and a self-locking motor 25. The secondary gear 22 is fixedly connected to the middle section of the outer wall of the rotating shaft 20. The main gear 24 is rotatably connected to the inner wall of the end of the telescopic plate 7 via a transmission shaft 23. The main gear 24 meshes with the secondary gear 22. The self-locking motor 25 is installed on one side of the outer wall of the telescopic plate 7. The end of its output shaft passes through the base frame 1 and is fixedly connected to one end of the transmission shaft 23. The self-locking motor 25 is used to drive the transmission shaft 23 to rotate and has a self-locking function.

[0030] When the self-locking motor 25 starts, it drives the transmission shaft 23 to rotate through its output shaft. The transmission shaft 23 drives the main gear 24 to rotate. When the main gear 24 rotates, it drives the secondary gear 22 that meshes with it to rotate. The secondary gear 22 then drives the baffle 21 to rotate through the rotating shaft 20. The baffle 21 rotates around the rotating shaft 20. When the baffle 21 rotates upward, its angle gradually increases until the baffle 21 is perpendicular to the telescopic plate 7. At this time, the self-locking motor 25 is turned off. Since the self-locking motor 25 has a self-locking function, it can lock the angle of the baffle 21. At this time, the baffle 21 and the two limit posts 8 form a limit structure.

[0031] Both uprights 2 have sliders 12 slidably connected to their inner walls. The two sliders 12 are fixedly connected to the outer walls of the lifting plate 5 near both ends. The two sliders 12 guide the lifting of the lifting plate 5, so that the lifting plate 5 moves smoothly and does not tilt when it is raised or lowered.

[0032] Multiple casters 4 are installed on the bottom outer wall of the base frame 1. The casters 4 are evenly distributed at the four corners of the base frame 1. The casters 4 have a braking function, which is existing technology and will not be described in detail.

[0033] The outer wall of the two supporting plates 6 on opposite sides is provided with a sliding groove 17. The connecting plate 18 is slidably connected to the two sliding grooves 17. The sliding grooves 17 play a role in avoiding collisions, so that the two telescopic plates 7 can drive the connecting plate 18 to slide between the two supporting plates 6.

[0034] The implementation principle of the compressor maintenance mobile device in this application embodiment is as follows: When in use, push the handle 3 to drive the base frame 1 to move. The base frame 1 is easy to move by the rolling of multiple universal wheels 4. Move the base frame 1 to the vicinity of the compressor to be transferred. Drive the lifting plate 5 to descend through the lifting mechanism, so that the bearing plate 6 drives the telescopic plate 7 to be located below the compressor. Then, drive the telescopic plate 7 to extend into the bearing plate 6 through the telescopic mechanism until the two telescopic plates 7 are located at the bottom of the compressor and the ends of the two telescopic plates 7 completely pass under the compressor. Drive the lifting plate 5 to rise through the lifting mechanism, so that the compressor is lifted by the bearing plate 6 and the telescopic plate 7, realizing the automatic handling function without manual handling.

[0035] In the limiting assembly, the self-locking motor 25 drives the baffle 21 to rotate, making the baffle 21 perpendicular to the telescopic plate 7. At this time, the two baffles 21 correspond to the two limiting posts 8. The telescopic mechanism drives the telescopic plate 7 to retract. When the telescopic plate 7 retracts, it moves the baffle 21 closer to the outer wall of the compressor. As the telescopic plate 7 continuously retracts into the bearing plate 6, the baffle 21 can continuously push the compressor above the bearing plate 6 until the side of the compressor away from the two baffles 21 abuts against the two limiting posts 8. At this time, the two limiting posts 8 and the two baffles 21 cooperate to limit the compressor, so that the compressor is always in a stable state during the movement of the moving device.
