Description

Technical Field

[0001] The utility model relates to the technical field of the combined installation of axles and chassis, in particular to a device for the combined installation of axles and chassis of semi-trailers. Background Art

[0002] The combined installation of axles and chassis of semi-trailers is usually a continuous process, which involves accurately aligning the axles with the connection points on the chassis, fixing them with fasteners such as bolts and pins, adjusting the axles to adapt to different loads and road conditions, then conducting a comprehensive inspection to ensure the correctness and safety of the installation, and finally verifying the performance of the vehicle through actual road tests.

[0003] The existing combined installation of axles and chassis of semi-trailers is to lift the chassis and then roll the axles under the chassis for installation. When the chassis is lifted, it will shake, resulting in the need to wait for it to be stationary before installation, and there will also be shaking during installation, which will affect the installation efficiency of workers and reduce the work efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a device for the combined installation of axles and chassis of semi-trailers.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for the combined installation of axles and chassis of semi-trailers, including a chassis. Both sides of the lower end of the chassis are provided with a lifting assembly. The lifting assembly includes a placing table arranged under the chassis. Both ends of the placing table are fixedly connected with fixing frames. On the opposite sides of the two fixing frames, a clamping mechanism connected to the placing table is provided. A hydraulic press is arranged under the placing table. The telescopic end of the hydraulic press is fixedly connected with a support frame. The support frame is fixedly connected to the lower end of the placing table. A driving mechanism connected to the clamping mechanism is arranged inside the support frame.

[0007] As a further improvement of the utility model, a plurality of axles are arranged between the two lifting assemblies, and all the axles are arranged under the chassis.

[0008] As a further improvement of the utility model, the clamping mechanism includes a U-shaped frame slidably connected to the upper end of the placing table. The lower end of the U-shaped frame is fixedly connected with a connecting block integrally formed therewith. The connecting block slides on the lower end of the placing table, and a threaded hole is opened on the connecting block.

[0009] As a further improvement of the present utility model, the driving mechanism includes a double-headed motor fixedly connected to the lower end of the placement table. The double-headed motor is located inside the support frame. The left and right output shaft ends of the double-headed motor are respectively fixedly connected with a first threaded rod and a second threaded rod. The ends of the first threaded rod and the second threaded rod that are away from each other respectively thread through the threaded holes and are rotatably connected to the side wall of the fixed frame.

[0010] As a further improvement of the present utility model, clamping blocks are fixedly connected to the side walls of the two U-shaped frames that are close to each other. Both of the clamping blocks are made of rubber.

[0011] As a further improvement of the present utility model, the threading directions of the first threaded rod and the second threaded rod are opposite.

[0012] The beneficial effects of the present utility model:

[0013] By providing a hydraulic press and a chassis, the placement table can be lifted or lowered by starting the two hydraulic presses, thereby indirectly lifting or lowering the chassis. The lifting of the chassis enables the axle to be better placed under the chassis, facilitating the assembly work for workers and improving work efficiency.

[0014] By providing a clamping mechanism and a driving mechanism, by driving the double-headed motor, the double-headed motor drives the first threaded rod and the second threaded rod to rotate respectively. When the first threaded rod and the second threaded rod rotate, they will respectively drive a threaded connection block to approach or move away from each other. When the two connection blocks approach each other, they can clamp the chassis, thereby preventing the chassis from shaking during installation, affecting the installation efficiency, and improving work efficiency.

[0015] The present utility model realizes the precise positioning and stable assembly of the chassis, significantly improving the assembly efficiency and installation quality. Description of the Drawings
