Vehicle-mounted foldable hydraulic suspension arm device

Abstract

The invention discloses a vehicle-mounted foldable hydraulic suspension arm device. The vehicle-mounted foldable hydraulic suspension arm device comprises a scissors fork foldable suspension arm and a hydraulic oil cylinder for driving the scissors fork foldable suspension arm to extend and retract, wherein the scissors fork foldable suspension arm is a diamond-shaped string telescopic frame formed by hinging a plurality of pairs of crossed hinged connecting rods in sequence; in a pair of crossed hinged connecting rods on the tail of the telescopic frame, a first mounting base movably connected with the connecting rods is arranged at the lower end of one connecting rod, and the lower end of the other connecting rod is arranged in a limiting guide groove of a suspension arm guide device; the front end of a piston rod of the hydraulic oil cylinder is directly or indirectly connected with the pair of connecting rods on the tail of the telescopic frame. By adopting the vehicle-mounted foldable hydraulic suspension arm device, the defect of influence on road traffic caused by a conveying pipeline during conveying of liquid goods through a vehicle in the prior art is overcome, and influence on the pass of other vehicles is lowered by hanging the conveying pipeline; the vehicle-mounted foldable hydraulic suspension arm device has the advantages of maneuverability, rapidness in unfolding and folding, and working stability.

Description

Technical field [0001] The invention relates to a vehicle-mounted device for hanging objects, and is particularly suitable for hanging a conveying pipeline when liquid goods are conveyed by tank vehicles. Background technique [0002] At present, when tank vehicles are transporting liquid goods, the transport pipelines are laid on the ground. When other vehicles need to pass, they must be bypassed. However, in some special occasions, such as fire fighting scenes, due to the narrow road surface and too many vehicles, other fire fighting vehicles detour too far to affect the fire fighting time. When forced through, the pipeline pressure suddenly rises, which is easy to cause Pipeline blasting currently only uses piles of soil on both sides of the pipeline to protect the pipeline. In addition to the long operation time, the problem has not been solved fundamentally, and pipeline blasting is often caused. Summary of the invention [0003] The purpose of the present invention is to ov...

However, in some special occasions, such as the fire fighting scene, due to the narrow road surface and too many vehicles, other fire fighting vehicles detoured too far to affect the fire extinguishing time. Pipeline blasting, at present, only uses soil on both sides of the pipeline for pipeline protection. In addition to the long operation time, it does not solve the problem fundamentally, and often causes pipeline blasting
