Problems solved by technology

After the oil circuit in the existing hydraulic shear expander enters the hydraulic 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 for users to use. very inefficient
[0003] In addition, the hydraulic shear expanders currently on the market, which are powered by an external power source, are medium and heavy hydraulic rescue equipment, and they are very heavy, which is not conducive to long-distance load handling and rescue implementation of rescue in extremely complicated and narrow spaces.

Embodiment Construction

[0042] Such as figure 1 As shown, the electric shear expander provided in this embodiment includes a shear expander working head 1 , a hydraulic drive assembly 2 , a reversing assembly 3 and an oil inlet assembly 4 . The shearing and expanding working head 1 includes two intersecting and movably connected shearing and expanding parts, each of which has a cutting edge 11 on the inside and an expanding part 12 on the outside. The hydraulic drive assembly 2 is connected to the shear expansion working head 1 to drive the two shear expansion parts to open or close. The reversing assembly 3 is connected with the hydraulic drive assembly 2 and provides the hydraulic drive assembly 2 with two oil circulations in opposite directions. The oil inlet assembly 4 is connected with the reversing assembly 3 .

[0043] The electric shear expander provided by the present invention integrates shearing and expansion, specifically:

[0044]In the cutting state, the hydraulic drive assembly 2 dr...

Abstract

The invention provides an electric shearing expander which comprises a shearing expanding work head, a hydraulic driving component, a reversing component and an oil feeding component, wherein the shearing expanding work head comprises two shearing expanding components which are crossing and moveably connected with each other; a shearing blade is arranged on the inner side of each shearing expanding component; an expanding part is arranged on the outer side of each shearing expanding component; the hydraulic driving component is connected with the shearing expanding work head and is used for driving the two shearing expanding components to open or close; the reversing component is connected with the hydraulic driving component and is used for supplying two oil-way loops along opposite directions to the hydraulic driving component; the oil feeding component is connected with the reversing component.

Description

technical field [0001] The invention relates to the technical field of disaster relief equipment, and in particular to an electric shear expander. Background technique [0002] The hydraulic shear expander is a rescue and demolition tool, which is used in natural disasters such as vehicle accidents, house collapses, fire scenes or earthquakes. It uses the functions of shearing, expanding, pulling and strengthening to demolish various metal or non-metallic structures. , Rescue victims trapped in dangerous environments, can be equipped with fire brigade, armed police force, expressway rapid response rescue team. After the oil circuit in the existing hydraulic shear expander enters the hydraulic 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 for users to use. Very inefficient. [0003] In addition, the hydraulic ...
