Hydraulic lifting platform

Abstract

The invention discloses a hydraulic lifting platform, which comprises a top plate and a bottom plate. The bottom of the top plate is fixedly connected with a hinge seat; the top plate is connected with a pin shaft through the hinge seat in a rotatable manner; the outer surface of the pin shaft is connected with a sleeve and a baffle plate in a sleeving manner; the bottom of the sleeve is fixedly connected with an upper ladder; one side of the sleeve is fixedly connected with a clamping seat; the bottom of one side of the clamping seat is fixedly connected with a limiting block; the outer surface of the upper ladder is welded with a fixed sleeve; the inner wall of the fixed sleeve is connected with a lower ladder in a sliding manner; one side of the lower ladder is provided with a cross rod; one end of the cross rod penetrates through and extends to the other side of the lower ladder; one end of the cross rod is in threaded connection with a nut; and the outer surface of the cross rod is fixedly connected with an antiskid layer. By the arrangement of the upper ladder, the lower ladder, the hinge seat, the pin shaft, the sleeve, the baffle plate, a torsion spring, the bottom plate, ashear bracket, a hydraulic cylinder and springs, the hydraulic lifting platform solves the problem that a worker gets onto and gets off the lifting platform inconveniently when the lifting platform drops down.

Description

technical field [0001] The invention relates to the technical field of lifting platforms, in particular to a hydraulic lifting platform. Background technique [0002] Mine mining requires the use of cranes. Cranes play a vital role in mining. Cranes refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. Also known as crane, aerial crane, crane. [0003] The main characteristics of the tire crane are: the driving cab and the lifting control room are combined into one, which is evolved from a crawler crane. The disadvantage of the board causing damage to the road surface belongs to the material handling machinery. [0004] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longi...
