Hydraulic ejector rod used for rescue

Abstract

The invention discloses a hydraulic ejector rod for rescue, which comprises a column, the outer surface of which is fixedly connected with a thickened lifting body, the front and rear surfaces of the thickened lifting body are inlaid with elastic nuts of the lifting body, and the top of the elastic nut of the lifting body The screw is connected with an operating handrail, and the right end of the thickened lifting body is provided with a lifting rocker. This type of hydraulic ejector for rescue is easier and faster to operate. The overall use of high-strength aluminum alloy material ensures strength. On the one hand, the weight on the hydraulic jack is greatly reduced, the supporting force is increased, and the problems of the original hydraulic jack are relatively small, the rescue is bulky and the space is small, and a steering handle and a chuck are provided. , and the steering handle can be clamped at any 360 degrees. During the rescue process, the angle can be beneficial to the space to work, and the chuck is in the shape of "U", and the chuck can be rotated, which effectively solves the problem of slow piston extension speed and efficiency. low problem.

Description

technical field [0001] The invention relates to the technical field of hydraulic ejector rods, in particular to a hydraulic ejector rod for rescue. Background technique [0002] The hydraulic rescue ejector rod has a large jacking force and light weight, and can provide a maximum jacking force of 110kn, which is sufficient for vehicle rescue and general rescue. It is mostly used for rescuing victims trapped in confined environments or rescuing victims in dangerous environments , the rescue ejector is an essential rescue tool for fire brigades, earthquake rescue teams, traffic police teams, industrial and mining enterprises, and other disaster relief departments. Rescue jacks are needed to support and fix dangerous objects to protect the rescuer and the rescued; when a traffic accident occurs, the rescue jack can be used to support, stabilize or lift parts of the vehicle as needed, and open a rescue channel for rescuers. Carry out rescue. [0003] However, the existing hydr...
