Shears-fork type hydraulic lifting electric flat carriage

Abstract

The invention discloses a shears-fork type hydraulic lifting electric flat carriage which comprises an electric flat carriage body and a table board. A fork frame is arranged between the electric flat carriage body and the table board and composed of an inner fork frame body and an outer fork frame body which are crossed. The middles of the inner and outer fork frame bodies are provided with holes in rotating fit with a pin shaft. The upper end of the outer fork frame body is hinged to a lug plate on the lower surface of the table board. The lower end of the outer fork frame body is provided with idler wheels which are in sliding fit with upper and lower sliding ways arranged on the electric flat carriage body transversely. The upper end of the inner fork frame body is provided with idler wheels which are in sliding fit with upper and lower sliding ways arranged on the table board transversely. The lower end of the inner fork frame body is hinged to a lug plate on the electric flat carriage body. Two hydraulic cylinders are symmetrically arranged between the electric flat carriage body and the table board, and a hydraulic station is arranged on the electric flat carriage body. The shears-fork hydraulic lifting electric flat carriage has the remarkable advantage that the table board stably ascends and descends on the condition that the table board requirement is too low.

Description

Technical field: [0001] The invention relates to an electric flat car, in particular to a scissor type hydraulic lifting electric flat car. Background technique: [0002] The lifting mechanism of the existing lifting electric flat car is to directly set a hydraulic cylinder under the table of the electric flat car, and the table is moved up and down through the expansion and contraction of the piston rod of the hydraulic cylinder. Because the hydraulic cylinder and the table are under a point force, the stability of the table is poor, especially when the table is unbalanced, it is easy to cause damage to the hydraulic cylinder and even break the piston rod; the second type of lifting mechanism is a scissor hydraulic The lifting mechanism raises and lowers the table. This kind of lifting mechanism overcomes the defects of the first structure. However, when the requirements for the table are too low, the space is limited to install the hydraulic cylinder and cannot be implemented. ...

AI Technical Summary

Problems solved by technology

Because the hydraulic cylinder and the table are under a point of force, the stability of the table is poor, especially in the case of partial load on the table, it is easy to cause damage to the hydraulic cylinder, or even break the piston rod; the second lifting mechanism is a scissor-type hydraulic The lifting mechanism makes the table rise and fall. This lifting mechanism overcomes the defects of the first structure, but when the requirements for the table are too low, the space is limited to install the hydraulic cylinder and cannot be implemented.
