Description

Technical Field

[0001] This invention relates to the field of magnetic nail transportation, and more specifically to a maintenance and repair device for magnetic nail buses. Background Technology

[0002] Lifts are commonly used for the maintenance and repair of magnetic nail buses. This equipment can raise the vehicle so that technicians can inspect and repair components such as the chassis, axles, and braking system. Lifts play an important role in ensuring safety and efficiency, making the maintenance process more convenient. With a stable lifting platform, technicians can carry out maintenance in a safe environment, reducing the risk of accidental injury. The vertical lifting design can make efficient use of workshop space and is suitable for various maintenance locations.

[0003] Chinese patent CN212532140U discloses a support mechanism for vehicle engineering maintenance, including a lifting bracket. The side of the lifting bracket is slidably connected to one side of a rear side plate, and the lower end of the rear side plate is fixedly connected to the rear side of a base plate.

[0009] Preferably, the adjustment assembly includes a power motor, an adjustment screw, and a lead screw slider. The power motor is fixedly installed on the top of the bar frame. The adjustment screw is rotatably disposed inside the bar frame, and the top end of the adjustment screw is fixedly connected to the output end of the power motor.

[0015] Preferably, the output end of the fan is equipped with a conveying pipe, and the other end of the conveying pipe is connected to the diversion channel.

[0016] The advantages of this invention are:

[0017] 1. The maintenance and repair device for magnetic nail buses described in this invention facilitates support and repair of buses of different sizes and models through the use of a bidirectional lead screw and an electric push rod, improving flexibility. The electric push rod moves the support bracket, and the servo motor drives the bidirectional lead screw, allowing adjustment of the spacing between support blocks on the same side. After moving the support blocks to the vehicle support point, the adjustment component moves to adjust the support blocks, thus supporting and lifting the vehicle, facilitating maintenance and repair of the vehicle chassis. This improves the flexibility of the maintenance and repair device for magnetic nail buses and facilitates support and repair of buses of different sizes and models.

[0018] 2. The maintenance and repair device for magnetic nail buses described in this invention facilitates the cleaning of the working environment through the setting of adjusting blocks and supporting blocks. The bottom of the supporting block is in contact with the top of the load-bearing plate. When the supporting block moves, it can remove impurities adsorbed on the top of the load-bearing plate, achieving partial cleaning of the load-bearing plate. When a complete cleaning of the load-bearing plate is required, the micro motor drives the threaded screw to rotate. The rotation of the threaded screw causes the threaded cylinder to move, which in turn drives the adjusting block to move synchronously. When the adjusting block moves out of the supporting block, it contacts one end of the opposing adjusting block. Then, through the movement of the bidirectional screw, the sliding block moves. The sliding block and the strip frame work together to drive the supporting block and the unfolded adjusting block to move, simultaneously causing the cleaning plate to contact the top of the load-bearing plate. When the supporting block moves, it drives the cleaning plate to move synchronously. Thus, the combination of the supporting block and the cleaning plate can scrape away impurities on the top of the load-bearing plate, thereby improving the cleanliness of the working area.

[0019] 3. The maintenance and repair device for magnetic nail buses described in this invention improves the cleanliness of the support block through the installation of a fan and cleaning components. When the sliding block moves, it drives the roller to rotate inside the groove. The roller supports the bottom of the strip frame. The rotation of the roller drives the pulley to rotate via a drive belt. The rotation of the pulley drives the fan to move, thereby generating airflow. The airflow is delivered through the conveying pipe and enters the distribution groove. The air entering the distribution groove flows to the surface of the support block through the air jet holes, which can remove impurities adsorbed on the surface of the support block and improve the cleanliness of the support block.

[0027] To better understand the technical solution of the present invention, detailed descriptions are provided below through specific embodiments:

[0028] like Figures 1 to 7As shown in the embodiment of the present invention, a maintenance and repair device for a magnetic nail bus includes a base plate 1, a load-bearing plate 3 fixedly installed on the base plate 1, inclined blocks 2 symmetrically installed on the load-bearing plate 3, brackets 8 symmetrically arranged on the top of the base plate 1, and the load-bearing plate 3 located between two sets of brackets 8. A bidirectional lead screw 9 is rotatably arranged inside the bracket 8, a servo motor 10 is fixedly installed inside the bracket 8, and the output end of the servo motor 10 is fixedly connected to one end of the bidirectional lead screw 9. Sliding blocks 11 are symmetrically arranged inside the bracket 8, and the bidirectional lead screw 9 is threadedly connected to the sliding blocks 11. A strip frame 13 is fixedly installed on the top of the sliding block 11, an adjustment component is arranged inside the strip frame 13, and a support block 20 is connected to the adjustment component. A support frame 31 is arrayed inside the load-bearing plate 3, an electric push rod 32 is fixedly installed inside the support frame 31, and one end of the electric push rod 32 is fixedly connected to the bracket 8. A guide component for guiding the bracket 8 is provided on the base plate 1.

[0029] When maintaining and repairing magnetic nail buses using the maintenance and repair device, the bus to be repaired is moved onto the support plate 3. Depending on the bus size, the electric push rod 32 is activated, pushing the support 8 to move. The guide assembly guides and adjusts the position of the support 8, ensuring its smooth movement. This movement of the support 8 adjusts the position of the support block 20, allowing it to move to the bottom of the bus. Simultaneously, the servo motor 10 drives the bidirectional lead screw 9, which in turn moves the sliding block 11. This movement of the sliding block 11 then moves the strip frame 13, allowing adjustment of the spacing between the support blocks 20 on the same side. After the support block 20 is moved to the vehicle's support point, the adjustment assembly is activated, adjusting the position of the support block 20. Once the support block 20 contacts the bottom of the bus, it lifts the bus, facilitating maintenance and repair of the bus's bottom. This improves the flexibility of the maintenance and repair device for magnetic nail buses and makes it easier to support and repair magnetic nail buses of different sizes and models.

[0030] like Figure 1 As shown, a column 4 is fixedly installed on the top of the base plate 1, and a controller 5 is fixedly installed on the column 4. The controller 5 is electrically connected to the servo motor 10 and the electric push rod 32 respectively. The column 4 provides installation space for the controller 5. The controller 5 can control the operation of the maintenance and repair device used for magnetic nail buses.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the guide assembly includes a slide groove 6, a guide rod 7, and a guide block 33. The slide groove 6 is arranged in an array inside the base plate 1. The guide rod 7 is fixedly installed inside the slide groove 6. The guide block 33 is fixedly installed at the bottom of the bracket 8, and the guide rod 7 passes through the corresponding guide block 33. When the bracket 8 moves left and right, it will drive the guide block 33 to slide on the guide rod 7. The guide rod 7 and the guide block 33 cooperate to guide the bracket 8, so that the bracket 8 moves smoothly.

[0032] like Figure 1 and Figure 4 As shown, the adjustment assembly includes a power motor 14, an adjusting screw 15, and a lead screw slider 16. The power motor 14 is fixedly installed on the top of the bar frame 13. The adjusting screw 15 is rotatably disposed inside the bar frame 13, and the top end of the adjusting screw 15 is fixedly connected to the output end of the power motor 14. The lead screw slider 16 is disposed inside the bar frame 13, and the adjusting screw 15 is threadedly connected to the lead screw slider 16. The lead screw slider 16 is fixedly connected to the support block 20. A limit block 18 is fixedly installed on the lead screw slider 16. A limit rod 19 passes through the inside of the limit block 18, and both ends of the limit rod 19 are fixedly connected to the bar frame 13. When the adjustment component is working to adjust the position of the support block 20, the power motor 14 drives the adjustment screw 15 to rotate. When the adjustment screw 15 rotates, the position of the lead screw slider 16 will move. When the lead screw slider 16 moves, it will drive the limit block 18 to slide on the limit rod 19, so that the lead screw slider 16 can move smoothly. In turn, the lead screw slider 16 can drive the support block 20 to move, so as to adjust the vertical displacement of the support block 20. The support block 20 can support and lift the vehicle, which facilitates the inspection and maintenance of the vehicle chassis.

[0033] like Figure 4 and Figure 5As shown, an adjusting block 21 is inserted inside the support block 20, and guide grooves 22 are symmetrically arranged on the adjusting block 21. A guide block 23 corresponding to the guide groove 22 is fixedly installed inside the support block 20, and the guide block 23 is engaged with the guide groove 22. A cleaning plate 24 is fixedly installed at the bottom of the adjusting block 21, and a drive assembly is provided inside the support block 20. By adjusting the movement of the components, the bottom of the support block 20 is brought into contact with the top of the load-bearing plate 3. When the support block 20 moves, impurities adsorbed on the top of the load-bearing plate 3 can be removed, achieving partial cleaning of the load-bearing plate 3. When a complete cleaning of the upper surface of the load-bearing plate 3 is required, the position of the adjusting block 21 is adjusted by driving the components. After the adjusting block 21 moves out of the support block 20, it will contact one end of the opposing adjusting block 21. Then, the bidirectional lead screw 9 moves, causing the sliding block 11 to move, which drives the strip frame 13 and the support block 20 and the unfolded adjusting block 21 to move together. When the cleaning plate 24 is in contact with the top of the load-bearing plate 3, the support block 20 drives the cleaning plate 24 to move synchronously. Through the cooperation of the support block 20 and the cleaning plate 24, impurities on the top of the load-bearing plate 3 can be scraped off, thereby improving the cleanliness of the working area.

[0034] like Figure 6 As shown, the drive assembly includes a threaded cylinder 25, a threaded screw 26, and a micro motor 27. The threaded cylinder 25 is fixedly installed inside the adjusting block 21, the threaded screw 26 is threadedly connected inside the threaded cylinder 25, and the micro motor 27 is fixedly installed inside the support block 20, with its output end fixedly connected to one end of the threaded screw 26. A rubber block 28 is fixedly installed on one end of the adjusting block 21. The micro motor 27 is electrically connected to the controller 5, and a cleaning component is provided on the support block 20. When the drive assembly moves to adjust the position of the adjusting block 21, the micro motor 27 drives the threaded screw 26 to rotate. The rotation of the threaded screw 26 causes the threaded cylinder 25 to move, which in turn drives the adjusting block 21 to move synchronously, thereby achieving the purpose of quickly adjusting the position of the adjusting block 21. When the opposing adjusting blocks 21 come into contact, the rubber block 28 can alleviate the impact force.

[0035] like Figure 4 As shown, the cleaning component includes a diversion channel 29 and jet holes 30. The diversion channel 29 is fixedly installed on the support block 20, and the jet holes 30 are arrayed on the diversion channel 29. The air entering the diversion channel 29 will flow to the surface of the support block 20 through the jet holes 30, which can remove the impurities adsorbed on the surface of the support block 20 and improve the cleanliness of the support block 20.

[0036] like Figure 3 As shown, the bracket 8 is provided with a roller groove 17, and the bottom of the sliding block 11 is equipped with a roller 36 corresponding to the roller groove 17. The bracket 8 provides installation space for the roller groove 17, and the roller 36 can slide inside the roller groove 17.

[0037] like Figure 7 As shown, the sliding block 11 has an installation groove 34 inside, and a fan 35 is fixedly installed inside the installation groove 34. A pulley 40 is fixedly installed on the impeller inside the fan 35, and a drive belt 39 is wound around the pulley 40. The drive belt 39 is connected to the roller 36 for transmission. A filter plate 38 is installed on the installation groove 34. A conveying pipe 37 is installed at the output end of the fan 35, and the other end of the conveying pipe 37 is connected to the diversion groove 29. When the sliding block 11 moves, it drives the roller 36 to rotate inside the groove 17. The roller 36 supports the bottom of the strip frame 13. Simultaneously, the rotation of the roller 36 drives the belt 39, which in turn drives the pulley 40 to rotate. The rotation of the pulley 40 drives the fan 35 to move, thus generating airflow. This airflow, through the conveying pipe 37, flows into the diversion groove 29, achieving self-cleaning airflow during movement.
