Device for lifting front overhang of cab and compressing front overhang springs

Abstract

The invention discloses a device for lifting a front overhang of a cab and compressing front overhang springs, and relates to the technical field of automobile manufacturing. The device comprises a base, a lifting table mounted on the base and capable of rising and falling, a hydraulic oil pump mounted on the lifting table and a hydraulic oil cylinder connected with the hydraulic oil pump, whereina piston rod of the hydraulic oil cylinder is vertically disposed; a lifting supporting beam is mounted at the top end of the piston rod; a placement groove for placing the front overhang is formed in the lifting supporting beam along a lengthwise direction of the lifting supporting beam; two hooks for hooking the cab are arranged on the base; the hooks are connected with the base through ropes;four universal wheels are arranged at the bottom of the base; and a manual push handle is arranged on the base. The device can easily lift the front overhang to assist the front overhang to be mountedand connected to the cab, and shock absorption springs mounted subsequently can provide pressure, so that the labor intensity is reduced to an extremely large extent, and the production efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a device for lifting the front suspension of a driver's cab and compressing the front suspension spring. Background technique [0002] During the manufacturing process of the truck, the front suspension (structural schematic diagram as shown in Figure 4 shown) to the lower part of the cab, and in the production workshop, the cab to be assembled is generally suspended by a crane, so it takes a lot of time to lift the front suspension with a certain weight and install it to the cab Large manpower will easily delay work efficiency. Not only that, after the front suspension is installed, it is also necessary to install springs at both ends of the front suspension for subsequent installation of shock absorbers. Compression, and because the elastic coefficient of the spring to be installed is relatively large, it will also consume a large amount of manpower during ins...
