Problems solved by technology

[0003] Most of the existing demolition firefighting devices are hydraulic type. After the oil circuit enters the oil cylinder, it can only circulate in one direction, that is, it can only drive the piston of the oil cylinder to move forward, and the retreat of the piston can only be realized after manually draining the oil. It is very inconvenient to use. Convenient, but the operation efficiency is very low, which seriously affects the rescue time

Embodiment Construction

[0042] Such as figure 1 As shown, the electrohydraulic device provided in this embodiment includes a working head 100 and a power pump 200 . The working head 100 includes a work piece 1 , a hydraulic drive assembly 2 and a reversing assembly 3 , and the hydraulic drive assembly 2 is connected to the work piece 1 to drive the work piece 1 to work. The reversing assembly 3 provides the hydraulic drive assembly 2 with oil circulation in two opposite directions. The power pump 200 is connected with the reversing assembly 3 and delivers hydraulic oil to the reversing assembly 3 .

[0043] In this embodiment, the work piece 1 is a shear. However, the present invention does not make any limitation thereto. In other embodiments, the workshop 1 can be other work pieces such as a shear expander, expander, or propper.

[0044]In this embodiment, the power pump 200 includes a driving motor 201 , a rotating shaft 202 , an impeller assembly 203 , an eccentric shaft 204 , a piston 205 an...

Abstract

The invention provides an electric hydraulic device. The electric hydraulic device comprises a working head and a power pump. The working head comprises a workpiece, a hydraulic driving assembly and a reversing assembly. The hydraulic driving assembly is connected with the workpiece to drive the workpiece to work. The reversing assembly provides oil circulation in two opposite directions for the hydraulic driving assembly and drives the hydraulic driving assembly to do reciprocating motion. The power pump is connected with the reversing assembly to deliver hydraulic oil for the reversing assembly.

Description

technical field [0001] The invention relates to the technical field of disaster relief equipment, in particular to an electrohydraulic device. Background technique [0002] The demolition fire-fighting device is widely used in the rescue of traffic accidents such as roads and railways, earthquake disaster rescue, building collapse rescue, air disaster, sea disaster rescue and fire accident scenes. It can break and cut obstacles and rescue them in the first time Trapped personnel are very important tools in emergency rescue and disaster relief. [0003] Most of the existing demolition firefighting devices are hydraulic type. After the oil circuit enters the oil cylinder, it can only circulate in one direction, that is, it can only drive the piston of the oil cylinder to move forward, and the retreat of the piston can only be realized after manually draining the oil. It is very inconvenient to use. It is convenient, but the operation efficiency is very low, which seriously af...
