Electric supporting and ejection device used for emergency rescue

Abstract

The invention discloses an electric supporting and ejection device used for emergency rescue, and particularly relates to the technical field of fire fighting. The electric supporting and ejection device comprises supporting seats, the number of the supporting seats is two, grooves are formed in the opposite faces of the two supporting seats, and two guide rods are fixedly connected in the grooves. Under pushing of first electric push rods, an ejection mechanism can smoothly achieve ejection, then the ejection mechanism can make contact with the surface of an object, meanwhile, under the extrusion effect of a connecting plate, a limiting assembly can firmly position the ejection mechanism, smooth supporting and ejection work on the object is guaranteed, the device adopts a multi-point ejection mode so that the device can be attached to the object better, the shape of the device and the shape of the object supporting face are kept consistent, and therefore the device can be suitable for supporting and ejection work in different complex environments, the problem of slippage is effectively prevented, the problem of hurting rescue workers or trapped persons is avoided, and therefore a safe and effective rescue channel can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of fire protection, and more specifically, the invention relates to an electric jack for emergency rescue. Background technique [0002] The electric rescue jack is a hydraulic rescue tool, which is mostly used to rescue victims trapped in a confined environment. Its main components are oil cylinders and piston push rods. Mechanical pumps, electric pumps, etc. are often used as power sources. The hydraulic pressure pushes the piston push rod out of the oil cylinder to realize the supporting function. [0003] The electric roof props in the prior art are generally composed of a support base, a driving structure and a support top plate, and both the support base and the support top plate are equipped with a flat plate, and the rescue scene is changeable, and it is difficult to apply to different complex environments when supporting the roof , easy to slip, causing injury to the trapped people, and in the proc...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric jack for emergency rescue. The technical problem to be solved by the present invention is: the electric jack of the prior art is difficult to apply In different complex environments, it is easy to slip off, causing injury to the trapped people, and in the process of supporting the roof, if the driving structure fails, it is easy to cause the roof supporter to drop rapidly, causing the propped up objects to fall again, which is easy to cause injury to the personnel. The problem of secondary injury
