Anti-slip multipurpose hydraulic expander

Abstract

The invention discloses an anti-slip multipurpose hydraulic expander. The anti-slip multipurpose hydraulic expander comprises an expansion arm main body, a barb belt and an inner insertion block, wherein the expansion arm main body is of a two-part symmetrical clamp type structure, each expansion arm main body is composed of two layers of symmetrical buckling structures, and the upper portion andthe lower portion of the expansion arm body are fixed through at least two bolts; a second rotating pin is vertically inserted into the two corners at the left end of the expansion arm main body, a connecting plate is fixedly connected to the top surface and the bottom surface of the second rotating pin, and the other end of the connecting plate is fixedly connected to the top surface and the bottom surface of the first rotating pin inserted into the two corners at the right end of the hydraulic machine body. According to the anti-slip multipurpose hydraulic expander, the various structures are matched with each other, so that an anti-slip multi-purpose hydraulic expansion machine structure is formed, the real-time control of expansion is guaranteed, the expansion speed and the expansion degree can be accurately controlled, and the smooth rescue can be guaranteed, a plurality of functions are achieved, multiple functions can be realized by one device, and the use value of the device isimproved.

Description

Technical field [0001] The invention belongs to the technical field of mechanical industrial equipment, and more specifically, relates to a non-slip multi-purpose hydraulic expansion machine. Background technique [0002] In an emergency, if a few seconds are wasted, it is possible to pay the price of life, and the hydraulic expansion device is used to rescue the trapped persons from the damaged vehicle in time. Such a device can also rescue the trapped people from the collapsed reinforced concrete structure after the earthquake. For example, a handheld hydraulic expander in the patent application CN201410578145.X is mainly composed of an expansion arm, a pointed head, a hydraulic device, and a top handle. The expansion arm is composed of two pointed arms with semicircular curved domes at the back of the upper and lower parts, and grooves are arranged on the inside of the curved domes; the hydraulic device includes a hydraulic cylinder, a hydraulic rod, a hydraulic hand crank, a ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an anti-slip multi-purpose hydraulic expansion machine to solve the problem that the existing hydraulic expansion machine and the hydraulic expansion machine in the above-mentioned patent are easy to use when cleaning buildings and gravel. It falls off during the expansion. Even if there is a protrusion on the outside of the expansion arm in the above patent, it is very easy to fall off when cleaning the plate. Once it falls off, it may cause greater obstacles to rescue. Even endanger the lives of internal personnel, and after the expansion, because the internal space is dark, it is difficult to provide auxiliary lighting from the outside, and the lack of understanding of the internal environment hinders rescue.
