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 an anti-slip multipurpose hydraulic expansion machine. Background technique

[0002] In an emergency, a few seconds lost can cost lives, and hydraulic expansion devices are used to free trapped people from damaged vehicles in time. Such a device can also rescue the trapped people from the collapsed reinforced concrete structure after an earthquake, such as a hand-held hydraulic expander in the patent application CN201410578145. The expansion arm is composed of upper and lower pointed arms with a semicircular curved dome at the rear, and there is a groove inside the curved dome; the hydraulic device includes a hydraulic cylinder, a hydraulic rod, a hydraulic hand crank, and the hydraulic rod and The pointed head in the curved dome is connected, and the grooved protrusion on the pointed head can engage and slide with the groove on the curved...
