Embodiment Construction

[0025] Referring to the accompanying drawings, the heavy object hydraulic lifting device in the figure includes a heavy object tray 1, a pair of parallelogram mechanism 2, and is characterized in that:

[0026] 1), one end of a pair of parallel arms of the parallelogram mechanism 2 is hinged to the fixing seat 1-3, the other end is hinged to the upper end of the bracket arm, and the lower end of the bracket arm is bent at an angle and fixed with the bracket 1-1 , can always maintain the horizontal state of the bracket when the quadrilateral mechanism moves; the hydraulic cylinder 1-2 provides power for the parallelogram mechanism, driven by the hydraulic cylinder, the parallelogram mechanism unfolds forward around the hinge point of the fixed seat and falls, or to raised and folded;

[0027] 2), the heavy object tray 1 is installed on the bracket 1-1 of the parallelogram mechanism through the slide rail 6, wherein the heavy object tray 1 is fixed with the upper bracket 6-1 of ...

Abstract

The invention relates to a hydraulic pallet type load lifting device applicable to small space. The device comprises a load pallet and a pair of parallelogrammic mechanisms and is characterized in that one end of each of the parallel arms of each parallelogrammic mechanism is hinged on a fixed seat, the other end is articulated with the upper end of a bracket arm, and the lower end of the bracket arm is angularly bent and fixed with a bracket; under the drive of a hydraulic cylinder, the parallelogrammic mechanisms are expanded forwards and descend, or are folded by ascending backwards, around a hinging point of each fixed seat; the load pallet is arranged on the bracket of the parallelogrammic mechanisms by sliding rails; and auxiliary supporting rollers on the sliding rails are matched with fixed sliding grooves so as to support the load pallet kept between the two fixing seats. The invention solves the problem of frequent loading and unloading of loads in a narrow operating space, and has the advantages of simple structure, high working reliability and convenient operation and maintenance.

Description

technical field [0001] The invention relates to a hydraulic lifting device, in particular to a tray-type hydraulic lifting device for heavy objects suitable for narrow spaces. technical background [0002] During the transportation and loading and unloading of items, it is often necessary to remove an object with a certain volume and weight from a small space and lower it to a certain height, so as to facilitate the loading and unloading of the item, or return it to its original place after use. [0003] In general, separate loading and unloading machinery can be used to unload or load heavy objects into this space, such as forklifts. If the heavy object needs to be loaded on a transport vehicle and needs to be unloaded after arriving at the destination, if there is no separate external loading and unloading machinery, only the vehicle-mounted loading and unloading equipment can be used. Contents of the invention [0004] Aiming at the problems existing in the prior art, ...
