Abstract
The invention provides a hydraulic shearing device structure used for emergency rescue and special operation, wherein shearing arms are arranged at the side of a hydraulic cylinder, and tail ends of the hydraulic cylinder and end parts of a piston rod are respectively connected with the shearing arms by hinging mechanisms; the shearing arms are basically of an L-shape, and the two shearing arms are mutually connected by a middle pin shaft at the turning point of the L-shape; and when oil enters the hydraulic cylinder and pushes the piston rod to stretch, one end of each shearing arm moves with the piston rod so as to drive a shearing knife at the other end to close at the same time and complete a shearing action. The invention has the advantages of more obvious lever amplification effect of the shearing arms, larger area of hydraulic effect and shearing force enhancement under the conditions of the same size and oil pressure of the hydraulic cylinder.
Description
Technical field
The present invention proposes a kind of hydraulic clipper that is used for rescue and job that requires special skills.
Background technology
Hydraulic clipper is the utensil of speedily carrying out rescue work of fire brigade and rescue and relief work department indispensability, is also adopted when the job that requires special skills by many industrial and mining enterprises.Hydraulic clipper is being brought into play crucial effect in tackling various sudden accidents and particular surroundings, obtained great social benefit and economic benefit.
Existing hydraulic clipper is as a pincers, and shear arm is made by aluminium alloy, and most advanced and sophisticated place is made by hot-rolled steel, thereby makes it obtain maximum intensity so that the inside of wedging vehicle or building.When piston rod stretched out, blade opened.When piston rod shrank, blade began to close up to object, and it is cut off.
Summary of the invention
The volume mass of the hydraulic clipper that uses is all bigger at present, mainly is reasons in structure, causes the arm of force short, and hydraulic coupling can not make full use of, and causes volume mass excessive, grips effort.
As shown in Figure 1, basic structure of the present invention is: hydraulic cylinder, piston, shear arm and shear knife.Shear arm is arranged in the side of hydraulic cylinder, cylinder ends is connected with two shear arms, one end respectively by linkage with the piston rod end, the other end of shear arm is equipped with shear knife, and the shear arm basic configuration is the L type, and two shear arms are connected to each other by middle bearing pin in the corner of L type.
Working condition of the present invention is as follows;
As shown in Figure 1, when the cylinder lower oil-feed, when top is fuel-displaced, promotes piston rod and outwards uphold, drive shear arm one end and open, the shear knife closure of the shear arm other end is implemented shear action simultaneously.Revert action is then finished in the oil-feed of hydraulic cylinder top when the bottom is fuel-displaced.
Compare with existing orcible entry device, the present invention has following advantage: shearing on the function, the existing hydraulic clipper arm of force is short, cylinder diameter is thick, and in the work of piston retraction stroke, the hydraulic action area is little, hydraulic coupling is little.The present invention adopts side direction opening type scissors, and the lever amplification of shear arm is obvious, and the piston extension stroke is finished shear action, and the oil pressure active area is bigger, and under same size and the oil pressure, shearing force of the present invention significantly increases.
This invention has very big variation relatively and on the present hydraulic clipper structure, and makes it in shearing work usefulness, and all there has been improvement aspects such as structure optimization.
Description of drawings
Fig. 1 is a hydraulic clipper structural representation of the present invention.
Claims (2)
1. hydraulic clipper, it is characterized in that: power source is hydraulic cylinder and piston mechanism, and shear knife is arranged in the side of hydraulic cylinder, is connected with two shear arms, one end respectively by linkage with the piston rod end in cylinder ends.
2. require described hydraulic clipper according to right 1, its feature also is: the shear arm basic configuration is the L type, and two shear arms connect by middle bearing pin in the corner of L type, and when shear arm one end opens, the shear knife of the other end is then closed, finishes shear action.
