Problems solved by technology

[0003] The present invention aims at the fact that the current hydraulic shears are mostly fixed handles, and the steel bars at high places cannot be cut directly by hydraulic shears, and can only be used when they are close to the sheared objects with the help of external force. To solve the problem of increasing the difficulty of rescue in an emergency, a retractable hydraulic shear was designed

Embodiment Construction

[0014] Such as figure 1 Shown: a retractable hydraulic shear, its structure includes: a cutting head, a first handle, a first telescopic rod, a second handle, and a second telescopic rod; the cutting head is forged by two blades, connected below the cutting head There are a first handle and a second handle. The first handle and the second handle are connected to the shear head through a piston and a piston push rod. The top of the first handle is threaded with a first telescopic rod, and the top of the second handle is threaded. A second telescopic rod is installed; the blade is forged from hot-rolled steel; the piston in the first handle and the second handle and the piston push rod are cast from hot-rolled alloy steel; the first handle and the second handle Distributed symmetrically from top to bottom; the first telescopic rod is nested inside the first handle, the second telescopic rod is nested inside the second handle, and the top parts of the first and second telescopic r...

Abstract

The invention discloses a retractable hydraulic shear, which belongs to the field of mechanical equipment and mainly solves the problem that most of the current hydraulic shears have fixed handles, and the steel bars at high places cannot be directly cut by hydraulic shears, and can only be used when they are close to the sheared object by means of external force. , this operation is not only time-consuming and labor-intensive, but also increases the cutting time and increases the difficulty of rescue in case of emergency. The cutting head is forged from two blades. , The second handle is connected with the shearing head through the piston and the piston push rod, the first telescopic rod is mounted on the thread at the top of the first handle, and the second telescopic rod is mounted on the thread at the top of the second handle. The gap between the blades of the present invention is adjusted by the handle, which is fast, accurate and convenient. The precision sliding guide rail is used to eliminate the gap between the guide rails, and the cutting quality is high. Complete cutting work, easy to use.

Description

Technical field [0001] The invention relates to a retractable hydraulic shear, which belongs to the field of mechanical equipment. Background technique [0002] Hydraulic shears can bite open metals and other materials used in vehicles, and can realize rapid cutting function. When disasters such as fires and traffic accidents occur, hydraulic shears can quickly and effectively cut anti-theft doors and windows, steel protective railings, automobiles and other metal or Non-metallic structure, to rescue victims trapped in a restricted environment or rescue victims in a dangerous environment, to achieve the purpose of rescue or disaster relief, it is necessary for the fire brigade, traffic police team, industrial and mining enterprises and other disaster relief departments Demolition tools, currently hydraulic shears are mostly fixed handles. For high steel bars, hydraulic shears cannot be used to directly cut them. They can only be used when they are close to the cut object with the...
