Description

A car chassis support lifting device Technical Field

[0001] This utility model relates to the field of automobile chassis support and lifting, and in particular to an automobile chassis support and lifting device. Background Technology

[0002] The car chassis usually serves as the basic structural frame of a vehicle. The car chassis is typically a functional whole consisting of the transmission system, driving system, steering system, and braking system. When the car chassis is being inspected or repaired, it is usually supported and raised or lowered, which involves the use of support and lifting devices.

[0003] Existing automotive chassis support and lifting devices typically include a pit, a base plate, a hydraulic frame, and support plates. The base plate is installed inside the pit, the hydraulic frame is installed on top of the base plate, and the support plates are installed at the bottom of the hydraulic frame. This allows the automotive chassis to move to the bottom of the two support plates, and then the hydraulic frame is used to lift the support plates, thereby lifting the automotive chassis.

[0004] Adjacent hydraulic frames are usually set at a fixed distance, and thus the distance between the two support plates is fixed. However, different types of car chassis have different sizes. If the support plates can only contact the car chassis at their edges, it is easy to cause the car chassis to be unstable when lifted, which may result in some car chassis being restricted in use and affecting the stability of the car chassis lifting. Therefore, it is necessary for the car chassis support lifting device to adjust the distance between adjacent hydraulic frames according to the needs. Summary of the Invention

[0005] The purpose of this utility model is to provide an automobile chassis support lifting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car chassis support lifting device, comprising:

[0007] The base plate has a support frame symmetrically arranged on its top, and a hydraulic frame is installed inside the support frame;

[0008] A support plate, which is mounted on top of the hydraulic frame;

[0009] An adjustment mechanism is located on the base plate and is used to adjust the distance between adjacent support frames.

[0010] Preferably, the adjustment mechanism includes:

[0011] A driving component, the driving component being located on the side of the base plate;

[0012] The first groove is formed at the top of the base plate;

[0013] An adjusting screw is rotatably connected to the inside of the first groove.

[0014] The drive plate is fixedly connected to the bottom of the support frame and is slidably inserted into the interior of the first groove. The adjusting screw is threadedly inserted into the drive plate.

[0015] Preferably, the adjustment mechanism further includes:

[0016] A guide plate, which is fixedly connected to the bottom of the support frame;

[0017] The second groove is formed at the top of the base plate, and the guide plate is slidably inserted into the interior of the second groove.

[0018] A guide rod is fixedly connected to the inside of the second groove, and the outer wall of the guide rod is slidably inserted into the guide plate.

[0019] An auxiliary component is located on the side of the support frame.

[0020] Preferably, the driving element includes:

[0021] A support plate, which is fixedly connected to the side of the base plate;

[0022] A servo motor is mounted on the top of a support plate, and the output end of the servo motor is connected to the end of an adjusting lead screw.

[0023] Preferably, the auxiliary component includes:

[0024] A positioning plate, which is fixedly connected to the side of the support frame;

[0025] A fastening bolt is threadedly inserted into the top of the positioning plate, and the end of the fastening bolt is in contact with the top of the base plate.

[0026] Preferably, the auxiliary component further includes:

[0027] A measuring ruler, which is fixedly embedded in the top of the base plate;

[0028] An indicator plate is fixedly connected to the side of the positioning plate and is located on top of the measuring ruler.

[0029] The technical effects and advantages of this utility model are as follows:

[0030] This invention utilizes the cooperation of a driving component, an adjusting screw, a driving plate, and auxiliary components. A servo motor drives the adjusting screw to rotate, which in turn drives two driving plates to move simultaneously. This causes the two support frames to move closer or further apart, adjusting the distance between the two hydraulic frames and the support plates. Fastening bolts lock the positioning plate and the base plate in place. This allows for adjustment of the distance between adjacent support plates according to the dimensions of the car chassis, adapting to different support positions on the bottom of different car chassis and improving the stability of the car chassis support.
