Problems solved by technology

After the oil circuit in the existing jacker enters the oil cylinder, it can only circulate in one direction, that is, it can only drive the piston to move forward, and the retreat of the piston can only be realized after manually draining the oil. It is very inconvenient to use and the work efficiency is very low.

Abstract

The invention provides an electric supporting device which comprises a supporting assembly, a hydraulic drive assembly, a reversing assembly and an oil inlet assembly. The supporting assembly comprises a supporting block and a supporting column. The hydraulic drive assembly comprises an oil cylinder, an oil cylinder piston and an oil cylinder piston, and the oil cylinder pistons are connected with the supporting block. The reversing assembly is connected with the hydraulic drive assembly, and two kinds of opposite-direction oil way circulation are provided for the hydraulic drive assembly. The oil inlet assembly is connected with the reversing assembly.

Description

technical field [0001] The invention relates to the technical field of disaster relief equipment, and in particular relates to an electric jack. Background technique [0002] The jack is a hydraulic rescue and demolition tool, which has the advantages of light weight and small size. Compared with other non-hydraulic working machines, it has the advantages of stable operation and low noise. Therefore, it is used as a flowing power source and tool , It is widely used in firefighting, roads, ports, airports, railways, factories and mines, communities and various emergency rescue operations in natural disasters. [0003] The structure of the jacking device includes an oil cylinder, a manual valve and a jacking assembly. When working, turn the manual control valve to make the oil enter the oil cylinder, and the piston will extend the propping assembly to the place to be propped, and the object to be propped will be propped apart by the continuous movement of the piston. After t...
