Description

Technical Field

[0001] This utility model relates to the field of automobile repair, and in particular to a gantry four-wheel alignment lift. Background Technology

[0002] During the vehicle maintenance process, operations such as tire repair and replacement, chassis repair, replacement and repair of new energy vehicle battery packs, and four-wheel alignment all require lifting the vehicle as a whole. After the vehicle is lifted, it is convenient for personnel to inspect and repair the vehicle's tires and under-body structure.

[0003] Currently, gantry four-wheel alignment lifts generally use chain and wire rope structures as the transmission structure, while the basic frame is a gantry structure, and a safety system is added to prevent accidental descent.

[0004] However, existing gantry four-wheel alignment lifts have relatively limited functionality and are mostly designed for use with gasoline vehicles. Compared to the undercarriage structure of new energy vehicles, the chassis has limited operational space, which affects the replacement and maintenance of battery packs in new energy vehicles. At the same time, the chain drive structure is relatively complex, resulting in a higher failure rate. Utility Model Content

[0005] In order to overcome the problems that the existing gantry four-wheel alignment lift has limited functionality, is not convenient for maintenance of new energy vehicle battery packs, and has a complex chain transmission structure that leads to a high failure rate.

[0006] The technical solution of this utility model is as follows: a gantry four-wheel positioning lift, including fixed columns, a guide bridge and a lifting module. Two fixed columns are symmetrically arranged. The bottom of each fixed column is fixedly connected to a fixed base. The top of each fixed column is fixedly connected through a connecting seat. The inner side of each fixed column is respectively provided with a main hydraulic cylinder and a secondary hydraulic cylinder. An electro-hydraulic pump station is provided at the right end of the surface of the fixed column. Safety blocks are rotatably installed on the outer side of the surface of each fixed column through an ear plate seat. The lower end of each safety block is connected to an AC electromagnet through a connecting rod structure. Lifting seats are slidably installed on the inner side of each fixed column.

[0007] The lifting module is located between two fixed columns, and two sets of guide bridges are symmetrically arranged on both sides of the lifting module. Each set of guide bridges has two bridges and the guide bridges are designed in a triangular structure. The lifting module consists of a frame and a moving platform. The upper two sides of the frame are fixedly connected to the bottom of the two lifting seats respectively. Work platforms are set at both the front and rear ends of the frame. There are two work platforms on the left and right sides of the frame, and a scissor-type hydraulic lifting structure is set between the two work platforms.

[0008] Preferably, by using the inverted installation of the main hydraulic cylinder and the auxiliary hydraulic cylinder, the lifting platform can be driven to move up and down synchronously, thereby lifting the car. This simplifies the transmission structure, reduces the probability of failure and the amount of installation work, and increases safety. The safety block provides anti-fall protection, further enhancing safety. At the same time, the moving platform can slide outwards, increasing the chassis's operating space and facilitating battery pack maintenance for new energy vehicles, thus improving practicality.

[0009] Preferably, the upper ends of both the main hydraulic cylinder and the auxiliary hydraulic cylinder are fixedly connected to the top of the fixed column, and the output ends of the main hydraulic cylinder and the auxiliary hydraulic cylinder are fixedly connected to the lifting seat respectively.

[0010] Preferably, the output end of the electro-hydraulic pump station is equipped with a main oil pipe and a leveling and replenishing oil pipe, which are respectively connected to the upper and lower ends of the main engine cylinder, and the main engine cylinder and the auxiliary engine cylinder are connected through the main and auxiliary engine oil pipes.

[0011] Preferably, the lifting platform is equipped with a fall arrestor plate, which has square locking holes that are evenly spaced. The outer side of the fixed column surface has corresponding through holes, and the end of the safety block is engaged with the square locking holes through the through holes.

[0012] Preferably, the AC electromagnet is fixedly connected to the fixed column, the stroke of the electromagnet is 20 mm, and a torsion spring is provided between the safety block and the ear plate seat.

[0013] Preferably, two mobile platforms are provided on the left and right sides of the frame, and the mobile platforms are slidably connected to the frame via slide rails. Mounting sleeves are fixedly installed on both sides of the lower end of the mobile platforms, and manual pins are installed in the mounting sleeves. Pin holes are opened on the surface of the frame, and the manual pins are connected to the pin holes.

[0014] Preferably, a rotating platform is provided on the inner side of the frame, located on the side of the moving platform. Two rotating platforms are symmetrically arranged, and the two rotating platforms are rotatably connected to both ends of the frame. A support frame is provided at the bottom of the rotating platform at the end away from the frame, and rollers are provided at the bottom of the support frame.

[0015] The beneficial effects of this utility model are:

[0016] 1. This gantry four-wheel positioning lift uses the inverted installation of the main hydraulic cylinder and the auxiliary hydraulic cylinder, and the connection of the main and auxiliary hydraulic pipes, so that the hydraulic cylinder drives the lifting seat to move up and down, thereby achieving lifting. This simplifies the transmission structure, reduces the probability of failure and the amount of installation work, and increases the safety of use.

[0017] 2. The gantry four-wheel alignment lift has a movable platform structure, which allows the platform to slide inwards to align with the worktables on both sides. It is fixed by connecting a manual pin rod and a pin hole. In the maintenance of new energy vehicle battery packs, the manual pin rod can be pulled out to slide the platform outwards, increasing the chassis's operating space, making it easier to adapt to different usage needs and improving its practicality.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1-7This utility model provides an embodiment of a gantry four-wheel positioning lift, including a fixed column 1, a guide bridge 2, and a lifting module. Two fixed columns 1 are symmetrically arranged. The bottom of each fixed column 1 is fixedly connected to a fixed base 3. The top of each fixed column 1 is fixedly connected through a connecting seat 4. A main hydraulic cylinder 5 and an auxiliary hydraulic cylinder 6 are respectively arranged on the inner side of each fixed column 1. An electro-hydraulic pump station 7 is arranged on the right end of the surface of the fixed column 1. Safety blocks 8 are rotatably installed on the outer side of the surface of each fixed column 1 through ear plates. The lower end of each safety block 8 is connected to an AC electromagnet 9 through a connecting rod structure. A lifting seat 10 is slidably installed on the inner side of each fixed column 1. The upper ends of the main hydraulic cylinder 5 and the auxiliary hydraulic cylinder 6 are fixedly connected to the top of the fixed column 1, and the output ends of the main hydraulic cylinder 5 and the auxiliary hydraulic cylinder 6 are fixedly connected to the lifting seat 10.

[0028] The lifting module is located between two fixed columns 1, and two sets of guide bridges 2 are symmetrically arranged on both sides of the lifting module. Each set of guide bridges 2 has two bridges, and the guide bridges 2 are designed in a triangular structure. The lifting module consists of a frame 11 and a moving platform 12. The upper two sides of the frame 11 are fixedly connected to the bottom of two lifting seats 10 respectively. Worktables 13 are set at both the front and rear ends of the frame 11. There are two worktables 13 on the left and right sides of the frame 11. A scissor-type hydraulic lifting structure 14 is set between the two worktables 13. By using the inverted installation of the main hydraulic cylinder 5 and the auxiliary hydraulic cylinder 6, the lifting seats 10 can be pushed to move up and down synchronously, thereby lifting the car. This simplifies the transmission structure, reduces the probability of failure and the amount of installation work, and increases the safety of use. The safety block 8 is used to realize anti-fall protection, which increases safety. At the same time, the moving platform 12 can slide. Sliding the moving platform 12 outward can increase the operating space of the chassis, which is convenient for adapting to the battery pack maintenance work of new energy vehicles and improves practicality.

[0029] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the output end of the electro-hydraulic pump station 7 is equipped with a main oil pipe and a leveling and replenishing oil pipe. The main oil pipe and the leveling and replenishing oil pipe are respectively connected to the upper and lower ends of the main cylinder 5. The main cylinder 5 and the auxiliary cylinder 6 are connected through the main and auxiliary oil pipes. The electro-hydraulic pump station 7 controls the oil circuit so that the main cylinder 5 and the auxiliary cylinder 6 can synchronously push the lifting seat 10 to move, which facilitates the lifting operation. The maximum lifting height is 1900mm and the maximum working load is 5000kg.

[0030] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, the lifting seat 10 is provided with a fall arrestor plate 101, which has square locking holes that are evenly spaced. The outer side of the surface of the fixed column 1 has corresponding through holes, and the end of the safety block 8 is engaged with the square locking holes through the through holes. The AC electromagnet 9 is fixedly connected to the fixed column 1, and the stroke of the AC electromagnet 9 is 20 mm. A torsion spring is provided between the safety block 8 and the ear plate seat. The extension and retraction of the AC electromagnet 9 can drive the safety block 8 to flip. After lifting, the safety block 8 moves and engages with the square locking holes through the through holes to limit the position of the lifting seat 10 and increase safety.

[0031] Please see Figure 3 , Figure 6 and Figure 7 In this embodiment, two movable platforms 12 are arranged on the left and right sides of the frame 11, and the movable platforms 12 are slidably connected to the frame 11 via slide rails. Mounting sleeves 121 are fixedly installed on both sides of the lower end of the movable platforms 12. Manual pins 122 are installed in the mounting sleeves 121. Pin holes are opened on the surface of the frame 11, and the manual pins 122 are connected to the pin holes. Rotating platforms 123 are arranged symmetrically on the inner side of the frame 11, located on the side of the movable platforms 12. The two rotating platforms 123 are rotatably connected to both ends of the frame 11, and the rotating platforms... A support frame is provided at the bottom of the end of 123 away from the frame 11. The bottom of the support frame is equipped with rollers. The moving platform 12 slides through the slide rail. The moving platform 12 moves inward to make it flush with the worktables 13 on both sides. The rotation of the rotating platform 123 can fill the gaps, which is convenient for four-wheel alignment. After lifting, the rotating platform 123 flips downward to pull out the manual pin 122 and disengage it from the pin hole, so that the moving platform 12 can slide outward, increasing the operating space of the chassis. This facilitates the maintenance and replacement of battery packs for new energy vehicles and improves practicality.

[0032] During operation, the lifting module is first moved to the bottom, and the car travels onto the work platform 13 via the ramps 2 on both sides. The electro-hydraulic pump station 7 controls the oil circuit, so that the main cylinder 5 and the auxiliary cylinder 6 can synchronously push the lifting seat 10 to move, lifting the car into the air. After moving to the appropriate position, the AC electromagnet 9 drives the safety block 8 to flip, so that it engages with the through hole and the square locking hole, limiting the position of the lifting seat 10 and increasing safety. During operation, the moving platform 12 slides inward via the slide rail, making it level with the work platforms 13 on both sides. The flipping of the rotating platform 123 can fill the gaps, facilitating four-wheel alignment. After lifting, the rotating platform 123 flips downward, pulling out the manual pin 122 and disengaging it from the pin hole, so that the moving platform 12 can slide outward, increasing the operating space of the chassis, facilitating the maintenance and replacement of new energy vehicle battery packs, and improving practicality.

[0033] Through the above steps, by using the inverted installation of the main hydraulic cylinder 5 and the auxiliary hydraulic cylinder 6, the lifting platform 10 can be driven to move up and down synchronously, thereby lifting the car. This simplifies the transmission structure, reduces the probability of failure and the amount of installation work, and increases safety. The safety block 8 provides anti-fall protection, further enhancing safety. At the same time, the moving platform 12 can slide outwards, increasing the chassis's operating space and facilitating the maintenance of battery packs for new energy vehicles. This improves practicality and addresses the problems of existing gantry four-wheel alignment lifts having limited functionality, making them unsuitable for the maintenance of battery packs for new energy vehicles, and the complex chain transmission structure leading to a high failure rate.
