Description

Technical Field

[0001] This utility model relates to the field of axle processing technology, specifically a tilting lifting device for axles. Background Technology

[0002] In the production and maintenance process of vehicle axles, flipping is a frequent and critical procedure. For example, during the assembly of vehicle axles, they need to be flipped at multiple angles so that workers can accurately install various components, ensuring the tightness and accuracy of the assembly. During the maintenance of vehicle axles, flipping them allows maintenance personnel to comprehensively inspect various parts of the axle for wear, cracks, and other defects, promptly identifying and repairing potential problems.

[0003] The patent titled "A Vehicle Axle Tilting Lifter," publication number CN216863401U, describes vehicle axles as large-sized, heavy-weight components. After production, these axles require handling, necessitating specialized lifting equipment due to their size and weight. However, existing axle tilting lifters simply lift the axle with a fixed hook, limiting their applicability. Furthermore, the hooks are not secure enough during tilting, potentially causing the axle to detach and damage, reducing product quality, increasing production costs, and ultimately diminishing the device's practicality. This new lifter, however, uses a dual-axis motor to drive the first threaded rod, facilitating easy axle tilting. Its simple operation and user-friendly design, combined with a telescopic rod and sliding plate, allow for adjustment of the semi-circular clamp position, making it suitable for different axle models and expanding its applicability.

[0004] However, the lifting process uses a lead screw to move the clamps. With prolonged use, the pressure load of the lifting device will be directly or indirectly transmitted to the lead screw, causing the lead screw to bend. Once the lead screw bends, it will directly cause the clamps to fail to close. Therefore, a tilting lifting device for vehicle axles is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a tilting and lifting device for vehicle axles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle axle tilting lifting device, comprising an upper lifting plate, an upper support frame fixedly connected to the upper lifting plate, a hanging column fixedly connected to the upper support frame, a drive column rotatably connected to the inner center of the upper lifting plate, a lower lifting plate fixedly connected to the bottom of the drive column, a plurality of lifting ropes fixedly connected to the side of the lower lifting plate away from the upper lifting plate, an electromagnetic locking block fixedly connected to the end of the lifting rope away from the lower lifting plate, a circular placement groove provided at the center of the electromagnetic locking block, an electromagnetic locking structure connected to the outside of the electromagnetic locking block, and a drive tilting structure fixedly connected to the upper lifting plate for driving the lower lifting plate and the lifted vehicle axle to tilt.

[0007] As a further preferred embodiment of this technical solution: the electromagnetic locking structure includes multiple locking rings, and the multiple electromagnetic locking blocks are divided into two groups, with two electromagnetic locking blocks in each group. The locking rings are fixedly connected to the outer walls of two of the electromagnetic locking blocks, and multiple movable grooves are provided on both sides of the other two electromagnetic locking blocks. Movable locking posts are slidably connected inside the movable grooves, and the movable locking posts and the two groups of electromagnetic locking blocks are all set as electromagnets.

[0008] As a further preferred embodiment of this technical solution: both sets of electromagnetic snap-fit ​​blocks have drive rollers rotatably connected inside their circular placement slots.

[0009] As a further preferred embodiment of this technical solution: the drive tilting structure includes multiple toothed plates, which are fixedly connected to the outside of the drive column. A drive motor is fixedly connected to the upper hanging plate, and a worm gear is fixedly connected to the output shaft of the drive motor. The worm gear meshes with the toothed plates.

[0010] As a further preferred embodiment of this technical solution: a plurality of guide sliding columns are fixedly connected to the lower hanging plate, and a guide groove is provided at the bottom of the upper hanging plate, with the guide sliding columns slidably connected to the inside of the guide groove.

[0011] As a further preferred embodiment of this technical solution: the inner wall of the upper support frame is fixedly connected with a plurality of reinforcing ribs, and the top of the drive column is rotatably connected to one end of the upper support frame near the drive column.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, compared with the traditional snap-fit ​​method, the electromagnetic locking structure utilizes the characteristics of electromagnets to generate magnetic force through energization to achieve automatic snap-fit, making the operation more convenient and efficient, significantly shortening the snap-fit ​​time and improving work efficiency. On the other hand, the tight cooperation between the movable snap-fit ​​column and the snap-fit ​​ring effectively avoids the separation phenomenon after the two electromagnetic snap-fit ​​blocks are surrounded, ensuring that the connection between the vehicle axle and the lifting device is stable and reliable during the hoisting process. Furthermore, the multiple electromagnetic snap-fit ​​blocks are connected by lifting ropes, which can distribute more pressure during the hoisting process and avoid excessive transmission of pressure load during the hoisting process, which may cause the hoisting to fail.

[0014] 2. In this utility model, after the drive motor is started, it drives the worm to rotate. The worm meshes with the toothed plate, which in turn drives the drive column to rotate continuously. Finally, the lower hanging plate drives the entire axle, which is lifted by the electromagnetic locking block, to rotate. When it is necessary to flip the axle in front and back, and top and bottom, the drive rollers connected inside the circular placement slots of the two sets of electromagnetic locking blocks are started to rotate continuously, which drives the axle to rotate around the center of the circular placement slot, thus achieving the flipping and rotation effect. Combined with the drive flipping structure and the guide device, the axle can maintain precision and stability during the flipping process in all directions, meeting the diverse needs of axle flipping in different production scenarios, and improving production efficiency and product quality.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1

[0023] Please see Figures 1-5 This utility model provides a technical solution: a vehicle axle tilting lifting device, including an upper lifting plate 1, an upper support frame 2 fixedly connected to the upper lifting plate 1, a hanging column 3 fixedly connected to the upper support frame 2, a drive column 4 rotatably connected to the inner center of the upper lifting plate 1, a lower lifting plate 5 fixedly connected to the bottom of the drive column 4, a plurality of lifting ropes 6 fixedly connected to the side of the lower lifting plate 5 away from the upper lifting plate 1, an electromagnetic locking block 7 fixedly connected to the end of the lifting ropes 6 away from the lower lifting plate 5, a circular placement groove is opened at the center of the electromagnetic locking block 7, an electromagnetic locking structure is connected to the outside of the electromagnetic locking block 7, and a drive tilting structure is fixedly connected to the upper lifting plate 1 for driving the lower lifting plate 5 and the lifted vehicle axle to tilt.

[0024] In this embodiment, specifically: during use, the user can connect the hook of the crane through the hanging column 3. After the connection is completed, the entire upper hanging plate 1 is lifted by the hanging column 3 and the upper support frame 2. After the lifting is completed, the two sets of electromagnetic locking blocks 7 are moved to the outside of the axle, and the two sets of electromagnetic locking blocks 7 are fastened to the axle through the electromagnetic locking structure. After the fastening is completed, the entire upper hanging plate 1 is lifted again. After the axle is lifted, the position can be flipped by the drive flipping structure.

[0025] like Figures 1-2 As shown, the electromagnetic locking structure includes multiple locking rings 9 and multiple electromagnetic locking blocks 7 divided into two groups, with two electromagnetic locking blocks 7 in each group. The locking rings 9 are fixedly connected to the outer walls of two of the electromagnetic locking blocks 7. Multiple movable grooves 11 are provided on both sides of the other two electromagnetic locking blocks 7. Movable locking posts 10 are slidably connected inside the movable grooves 11. The movable locking posts 10 and the two groups of electromagnetic locking blocks 7 are all set as electromagnets.

[0026] In this embodiment, specifically: during use, after the crane moves the two sets of electromagnetic locking blocks 7 to both sides of the axle, the two sets of electromagnetic locking blocks 7 can be energized respectively. When energized, the two electromagnetic locking blocks 7 in each set will move closer to each other. When they move closer to each other, each set of electromagnetic locking blocks 7 will lock onto the axle. The locking position of the axle is limited by the circular placement groove in each electromagnetic locking block 7. At the same time, when the two electromagnetic locking blocks 7 are close together, the movable locking post 10 will also be attracted by the other electromagnetic locking block 7. When attracted, the movable locking post 10 will slide inside the movable slide groove 11, thereby moving into the interior of the locking ring 9, thus forming a locking phenomenon and preventing the two electromagnetic locking blocks 7 from separating after they are enclosed.

[0027] Furthermore, when the movable locking pin 10 slides inside the movable slide groove 11, an elastic pull rope connected inside the movable slide groove 11 pulls and connects one end of the movable locking pin 10. After the electromagnetic locking block 7 loses its attraction to the movable locking pin 10, the elastic pull rope will rebound, thereby restoring the movable locking pin 10 to its original position, thus separating the two electromagnetic locking blocks 7 that are enclosed together.

[0028] like Figures 1-5 As shown, the drive tilting structure includes multiple toothed plates 12, which are fixedly connected to the outside of the drive column 4. A drive motor 13 is fixedly connected to the upper hanging plate 1, and a worm gear 14 is fixedly connected to the output shaft of the drive motor 13. The worm gear 14 is meshed with the toothed plates 12.

[0029] In this embodiment, specifically: after the axle is lifted, the operator can start the drive motor 13. When the drive motor 13 is started, it can drive the worm gear 14 to rotate. When the worm gear 14 rotates, it can drive the drive column 4 to rotate continuously with the meshing toothed plate 12. When the toothed plate 12 rotates continuously, it will drive the lower hanging plate 5 to rotate. When the lower hanging plate 5 rotates, it will drive the axle lifted by the lower electromagnetic latching block 7 to rotate as a whole, thereby completing the rotation and flipping phenomenon of the axle in the left and right directions.

[0030] like Figures 1-5 As shown, multiple guide sliding columns 16 are fixedly connected to the lower hanging plate 5, and a guide groove 15 is provided at the bottom of the upper hanging plate 1. The guide sliding columns 16 are slidably connected to the inside of the guide groove 15.

[0031] In this embodiment, specifically: during use, when the lower hanging plate 5 is rotating, the guide sliding post 16 is engaged inside the guide groove 15, thereby assisting in guiding the rotation of the lower hanging plate 5.

[0032] Example 2

[0033] A vehicle axle tilting device is provided. Considering that during use, the tilting of the vehicle axle is not limited to the left-right direction, but also includes the front-rear and top-bottom tilting. To address these issues, the following technical solution is proposed:

[0034] like Figure 2 As shown, drive rollers 8 are rotatably connected inside the circular placement slots of both sets of electromagnetic card blocks 7.

[0035] In this embodiment, specifically: by setting multiple drive rollers 8, after the two sets of electromagnetic locking blocks 7 lock the axle, multiple drive rollers 8 can be started to rotate continuously. When the multiple drive rollers 8 rotate continuously, they will drive the axle located inside the circular placement groove to rotate around the center of the circular placement groove, forming an overall flipping and rotating effect, thus achieving the flipping effect of each side of the axle.

[0036] like Figure 1 As shown, the inner wall of the upper support frame 2 is fixedly connected with multiple reinforcing ribs 17, and the top of the drive column 4 is rotatably connected to the end of the upper support frame 2 near the drive column 4.

[0037] In this embodiment, specifically: in order to ensure the stability of the upper support frame 2, multiple reinforcing ribs 17 are formed on the inner wall surface of the upper support frame 2. The reinforcing ribs 17 increase the stability of the upper support frame 2 in conjunction with the hanging column 3 during the lifting process, and the upper support frame 2 supports the top of the drive column 4.

[0038] Working principle: In use, the user first connects the entire device to the crane hook via the hanging column 3, and then lifts the upper plate 1 with the help of the hanging column 3 and the upper support frame 2. The inner wall of the upper support frame 2 is fixedly connected with multiple reinforcing ribs 17, which can enhance its stability during the lifting process in conjunction with the hanging column 3. At the same time, the top of the drive column 4 is rotatably connected to the end of the upper support frame 2 near the drive column 4, providing support for the drive column 4.

[0039] After the upper plate 1 is lifted, the two sets of electromagnetic locking blocks 7 are moved to the outside of the axle. At this time, the two sets of electromagnetic locking blocks 7 are energized. Since the two electromagnetic locking blocks 7 in each set and the movable locking post 10 are all set as electromagnets, after being energized, the two electromagnetic locking blocks 7 in each set will move closer to each other. The circular placement groove in each electromagnetic locking block 7 will lock and limit the axle. When the two electromagnetic locking blocks 7 move closer and fit together, the movable locking post 10 will be attracted by the other electromagnetic locking block 7, slide inside the movable slide groove 11 and enter the locking ring 9 to form a lock, preventing the two electromagnetic locking blocks 7 from separating after they are enclosed.

[0040] After the axle is engaged, the upper lifting plate 1 is lifted again to lift the axle. If the axle needs to be rotated or flipped in the left or right direction, the operator starts the drive motor 13. The drive motor 13 drives the worm gear 14 to rotate. The worm gear 14 meshes with the toothed plate 12 fixedly connected to the outside of the drive column 4, thereby driving the drive column 4 to rotate continuously. The drive column 4 drives the lower lifting plate 5 to rotate, and the lower lifting plate 5 in turn drives the entire axle lifted by the electromagnetic engagement block 7 below to rotate. During the rotation of the lower lifting plate 5, the guide sliding column 16 fixedly connected to the lower lifting plate 5 slides inside the guide groove 15 opened at the bottom of the upper lifting plate 1, guiding the rotation of the lower lifting plate 5.

[0041] If it is necessary to flip the axle in front and back, and top and bottom, since the circular placement slots of the two sets of electromagnetic locking blocks 7 are rotatably connected with drive rollers 8, after the two sets of electromagnetic locking blocks 7 form a locking on the axle, multiple drive rollers 8 are started to rotate continuously. The drive rollers 8 drive the axle located inside the circular placement slot to rotate around the center of the circular placement slot, thereby achieving the flipping and rotation effect and completing the flipping of each side of the axle.

[0042] When it is necessary to separate the two enclosing electromagnetic locking blocks 7, the electromagnetic locking blocks 7 lose their attraction to the movable locking post 10. At this time, the elastic pull rope connected inside the movable slide 11 and pulling the movable locking post 10 at one end will rebound, restoring the movable locking post 10 to its original position, and the two electromagnetic locking blocks 7 can be separated.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
