Swing type telescopic supporting leg device and container lateral face self loading and unloading transport cart

Abstract

The invention relates to a swing type telescopic supporting leg device and a container lateral face self loading and unloading transport cart. The swing type telescopic supporting leg device comprises an amplitude-variable oil cylinder, a swing supporting leg, a connecting plate, telescopic supporting legs, telescopic oil cylinders and a movable supporting foot, wherein one end of the amplitude-variable oil cylinder and the connecting plate are both hinged to a base, the other end of the amplitude-variable oil cylinder is connected to the connecting plate, the swing supporting leg is fixed to the connecting plate, the amplitude-variable oil cylinder drives the swing supporting leg to execute swing amplitude-variable motions relative to the base, the telescopic supporting legs and the telescopic oil cylinders are installed inside the swing supporting leg, each telescopic oil cylinder drives the corresponding telescopic supporting leg to execute stretching-out and drawing-back motions, and the movable supporting foot is hinged to the grounding end of one telescopic supporting leg. The swing type telescopic supporting leg device and the container lateral face self loading and unloading transport cart can achieve large-span adjustment, meet operation requirements under various working conditions, and are small in occupied space.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a swing-type telescopic outrigger device and a container side self-loading and unloading transport vehicle. Background technique [0002] The container side self-loading and unloading transport vehicle is a special vehicle that is equipped with a side self-loading and unloading device on the container transport vehicle to realize the loading, unloading and transportation of containers. It can improve the loading and unloading efficiency of road container transportation, reduce operating costs, and ensure production safety. [0003] The outrigger device of the self-loading and unloading vehicle on the side of the container is usually installed under or on the side of the self-loading device to provide support for the whole vehicle in the working state. Outrigger devices have roughly the following forms so far: one is "T-shaped outriggers", which are only arranged behind the v...

AI Technical Summary

Problems solved by technology

Outrigger devices have roughly the following forms so far: one is "T-shaped outriggers", which are only arranged behind the vehicle, and the departure angle of the vehicle is small; This kind of "oblique outrigger" structure takes up a lot of space, and affected by the overall size, its outrigger span is relatively small, and the stability of the vehicle is relatively poor; there is also a "horizontal telescopic plus swing outrigger "leg" structure, the fixed outriggers are placed horizontally, and the movable outriggers are hinged to the fixed outriggers. This outrigger device can only be installed between the crane and the chassis, which increases the height of the crane base and increases the overall The structural layout is difficult, and limited by the position of the fixed outriggers, the span of the outriggers is small, and the adaptability in the height direction is poor, so the utilization rate of its work site is not high
