Hydraulic lifting device of carrier

Abstract

The invention discloses a hydraulic lifting device of a carrier, and the device comprises a folding bearing platform and horizontal lifting mechanisms, and is characterized in that the folding bearing platform comprises a primary wedge-shaped tablet and a secondary tablet; the horizontal lifting mechanisms are symmetrically arranged on the left side and the right side of the folding bearing platform; each horizontal lifting mechanism comprises two parallel four-link mechanisms comprising front hinge supports on both sides, upper and lower lifting arms on both sides and rear hinge supports on both sides, and a hydraulic lifting mechanism; and each hydraulic lifting mechanism comprises a lifting oil cylinder and a piston rod. The device is fixedly arranged below a bottom plate at the tail of the carrier, the folding bearing platform and the horizontal lifting mechanisms can be folded and contained below the bottom plate at the tail of the carrier on the premise of not affecting the ground clearance of the carrier, so that the installation and the configuration of the device is not restricted by the type of the carrier, and the normal loading and unloading of the carrier are not affected; and when the device needs to be used, the lifting operation of the bearing platform can be realized only by unfolding the folding bearing platform from a part below the bottom plate at the tail of the carrier.

Description

technical field [0001] The invention relates to a logistics loading and unloading tool, and more specifically relates to a hydraulic lifting device for the tail of a carrying vehicle, which belongs to the technical field of vehicle tail lift lifting. Background technique [0002] With the rapid development of social economy, the transportation of goods by vehicles has become an important part of modern logistics. When loading and unloading cargo, if it is a heavy cargo, it is generally loaded and unloaded by a cargo lift forklift, which requires the cooperation of multiple people; if it is a smaller and lighter cargo, it is often loaded and unloaded by manpower, which is labor-intensive and affects the safety of fragile cargo. As a vehicle for transporting goods, can it have the function of loading and unloading machinery, so that the loading and unloading of goods can be completed conveniently and labor-savingly at any place where the vehicle arrives.

Problems solved by technology

At present, the car tailgate that appears on the market is used as a load-carrying platform, and it is turned over and pressed against the rear of the car. It needs to be fixed. To open and close the tailgate of the car, the tailgate must be lowered first. The operation is cumbersome and affects the appearance, and it can only be used on vans. Obviously It cannot meet the requirements of modern logistics, and the tailgate device of the prior art needs to be improved urgently
