Description
Technical Field
[0001] This application relates to the technical field of auxiliary devices, and in particular to an auxiliary machine for the maintenance and disassembly of maintenance training equipment. Background Technology
[0002] Maintenance training equipment is a device specifically designed for equipment maintenance and operation skills training. When the device needs to be repaired or disassembled, the device to be repaired is placed on auxiliary machinery, which is usually a lifting platform, to raise the device to a suitable height for easy repair.
[0003] For example, the utility model patent with publication number CN220502554U discloses a lifting platform device. The lifting platform is raised and lowered by driving the lead screw through a motor. When the motor is damaged or the load on the lifting platform is too large, the lifting platform will suddenly drop, and the items on the lifting platform may fall and injure the operator. This needs to be improved. Utility Model Content
[0004] The purpose of this application is to provide an auxiliary machine for the maintenance and disassembly of maintenance training equipment in order to improve the stability of the lifting platform.
[0005] This application provides a maintenance and training equipment repair and disassembly auxiliary machinery with the following technical solution: It includes a base frame, a lifting platform slidably connected to the base frame, and a lifting assembly connected to the base frame. The lifting assembly drives the lifting platform to rise and fall. The base frame is provided with at least two support components. Each support component includes a guide column connected to the lifting platform and a support block slidably connected to the base frame. The base frame is provided with clearance holes for sliding cooperation with the guide column. The guide column has several annular grooves along its length. The guide column is formed with connecting columns corresponding to the annular grooves one by one. The support block is provided with through holes for cooperation with the guide column and connecting holes for cooperation with the connecting columns. The connecting holes communicate with the through holes, and the radius of the connecting holes is smaller than the radius of the through holes.
[0006] By adopting the above technical solution, after the lifting platform's height is adjusted, one of the connecting columns aligns with the connecting hole. Moving the support block causes the connecting column to engage with the connecting hole, with part of the support block located within the annular groove. The support block provides support for the guide column and the lifting platform, thereby improving the stability of the lifting platform. Even if the motor fails, it prevents the lifting platform from suddenly descending, ensuring the safety of the auxiliary machinery. When the height of the lifting platform needs to be adjusted, the support block is moved in the opposite direction, causing the connecting column to disengage from the connecting hole and align with the through hole. The support block no longer restricts the lifting of the guide column and the lifting platform, thus allowing for height adjustment.
[0007] Optionally, the base frame is provided with a plurality of limiting structures corresponding one-to-one with the support block. The limiting structure includes two limiting plates disposed on the base frame, a limiting groove is formed between the two limiting plates, the clearance hole is located between the two limiting plates, the limiting groove communicates with the clearance hole, and the support block slides in cooperation with the limiting groove.
[0008] By adopting the above technical solution, when the support block slides, the sliding cooperation between the support block and the limiting groove plays a guiding and limiting role in the sliding of the support block, thereby improving the stability of the support block sliding.
[0009] Optionally, each of the limiting plates has a slidably connected positioning block on one side near the other limiting plate. The limiting plate is provided with a sliding groove for sliding cooperation with the positioning block. The sliding groove communicates with the limiting groove. The positioning block is connected to the limiting plate by an elastic element. Each of the opposite sides of the support block is provided with two positioning grooves for cooperation with the positioning block. One positioning block corresponds to two positioning grooves. When the positioning block is engaged in one of the positioning grooves, the through hole corresponds to the clearance hole. When the positioning block is engaged in the other positioning groove, the connecting hole corresponds to the clearance hole.
[0010] By adopting the above technical solution, when the support block slides, the positioning block is pressed out of one of the positioning grooves and gets stuck in the sliding groove. The elastic element is compressed and undergoes elastic deformation, maintaining a tendency to elastically return to its original position until the positioning block aligns with the other positioning groove. At this point, the elastic element elastically returns to its original position, forcing the positioning block to get stuck in the other positioning groove. The cooperation between the positioning block and the two positioning grooves enables the support block to move precisely to the corresponding position, that is, to achieve precise alignment between the through hole and the clearance hole, or precise alignment between the connecting hole and the clearance hole.
[0011] Optionally, the end of the positioning block away from the elastic element is arc-shaped.
[0012] By adopting the above technical solution, when the support block slides, the end of the positioning block away from the elastic element is arc-shaped, which makes it easy for the limiting plate to apply force to the positioning block and drive the positioning block to leave the positioning groove.
[0013] Optionally, one side of the limiting plate is connected to a cover plate for covering the support block, the cover plate being provided with a clearance hole communicating with the limiting groove, the clearance hole corresponding to the avoidance hole.
[0014] By adopting the above technical solution, the cover plate restricts the vertical sliding of the support block, preventing the support block from leaving the limiting groove during the sliding process.
[0015] Optionally, when the positioning block is engaged in one of the positioning slots, one end of the support block protrudes from the limiting slot; when the positioning block is engaged in the other positioning slot, the other end of the support block protrudes from the limiting slot.
[0016] By adopting the above technical solution, the operator can know whether the support block supports the lifting platform by knowing which end of the support block protrudes from the limiting groove.
[0017] Optionally, the lifting assembly includes two rotating rods rotatably connected to the base frame, connecting rods connected to both ends of the rotating rods, and a drive structure connected to the base frame. The drive structure drives the two rotating rods to rotate in opposite directions. The lifting platform is provided with four support columns corresponding to the connecting rods one by one. Each support column is provided with a passive part. The connecting rod is provided with a first waist-shaped hole that slides and engages with the passive part. The first waist-shaped hole is provided along the length direction of the connecting rod.
[0018] By adopting the above technical solution, the drive structure drives the two rotating rods to rotate in opposite directions, the connecting rod rotates around the axis of the corresponding rotating rod, and the inner wall of the first waist-shaped hole abuts against the passive part and can drive the support column to rise and fall, thereby realizing the lifting of the lifting platform.
[0019] Optionally, the base frame is provided with a guide groove for sliding engagement with the support column, and the base frame is provided with a second oblong hole communicating with the guide groove. The second oblong hole is provided along the height direction of the base frame and is used for sliding engagement with the connecting rod.
[0020] By adopting the above technical solution, when the support column is raised or lowered, the sliding cooperation between the support column and the guide groove plays a guiding and limiting role in the raising and lowering of the support column, thereby improving the stability of the lifting platform.
[0021] Optionally, the drive structure includes a worm gear connected to each of the rotating rods, a worm rotatably connected to the base frame, and a drive member connected to the base frame. The drive member is used to drive the worm to rotate, each of the worm gears meshes with the worm, and the worm is located between two of the worm gears.
[0022] By adopting the above technical solution, the driving component drives the worm gear to rotate around its own axis. The worm gear drives two worm wheels to rotate in opposite directions, that is, the two rotating rods rotate in opposite directions, thereby realizing the lifting of the platform. The rotation of the two rotating rods is connected through the worm gear and the two worm wheels, reducing the driving force and increasing the overall structural integrity.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When the height of the lifting platform is adjusted, one of the connecting columns corresponds to the connecting hole. The support block is moved so that the connecting column is inserted into the connecting hole. Part of the support block is located in the annular groove. The support block supports the guide column and the lifting platform, thereby improving the stability of the lifting platform. Even if the motor is damaged, the lifting platform will not suddenly drop, ensuring the safety of the auxiliary machinery.
[0024] 2. By indicating which end of the support block protrudes from the limiting groove, the operator can determine whether the support block supports the lifting platform. Attached Figure Description

[0040] Combination Figure 4 , Figure 5 and Figure 9As shown, the base frame 1 is connected to at least two support components 4. Taking this embodiment as an example, there are two support components 4, which are arranged opposite to each other. Two mounting rods 15 are connected between the two oppositely arranged vertical rods 11.
