Abstract
A kind of small-sized single interface hydraulic shear expands device, the piston rod front end axle of hydraulic jack connects two connecting rods, two connecting rod front ends are connected to the rear end of two cutting knifes, the middle part of two cutting knifes is connected on the bearing pin on the support of hydraulic jack front end jointly, there is hand handle support both sides, the cylinder cap of hydraulic jack rear end has bidirectional hydraulic lock, and cylinder cap rear end face connects single interface reversing hand wheel, and single interface reversing hand wheel rear end connects outer fuel feed pump; The outboard end of two cutting knifes has tooth, and there is arc-shaped gear the inner side of two cutting knifes.This weight of equipment is light; Whole length is less than, and extended distance is greater than 240mm, can save material.Cylinder diameter length is little, and cutting knife volume is little.Single Interface realization interface is adopted once to plug, by easy to use to inner side for high-pressure overflow valve spinning.Cutting expanded head part adopts internal thread to confine, and head is diminished, can stretch into narrower job space.Assembly of the parts simplified overhauling is convenient.
Description
Technical field
The utility model belongs to rescue and tears brokenly instrument open, and particularly the small-sized single interface hydraulic shear of one expands device.
Background technology
Rescuing dismounting instrument, be applied to car accident, house collapse, in the natural calamity such as scene of fire or earthquake, tear down various metal or nonmetal knot by shearing, expansion, tractive and blessing function, save the victim be confined in hazardous environment, can fire brigade be equipped to, People's Armed Police, highway fast reaction rescue group.The hydraulic shear expansion device that hydraulic power is provided by external connection power source of market sale, belong to Medium or severe type hydraulic disengaging equipment, weight is all very large, be unfavorable for that the rescue that the long-distance small space bearing a heavy burden carrying and extreme complexity implements orcible entry is implemented, and be double nip and be connected with pumping source, needing the time more grown like this when rescuing, having significant limitation.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of small-sized single interface hydraulic shear to expand device.
The technical solution of the utility model is:
A kind of small-sized single interface hydraulic shear expands device, it is characterized in that: the piston rod front end axle of hydraulic jack connects two connecting rods, two connecting rod front ends are connected to the rear end of two cutting knifes, the middle part of two cutting knifes is connected on the bearing pin on the support of hydraulic jack front end jointly, there is hand handle support both sides, the cylinder cap of hydraulic jack rear end has bidirectional hydraulic lock, and cylinder cap rear end face connects single interface reversing hand wheel, and single interface reversing hand wheel rear end connects outer fuel feed pump; The head of two cutting knifes has expansion head, and there is serrated teeth the inner side of two cutting knifes
The utility model effect is:
This small-sized single interface hydraulic shear expands device weight of equipment and is gently less than 9.5kg; Whole length is less than 650mm, and head thickness is at 88mm, and extended distance is greater than 240mm, can save a large amount of raw material.Cylinder diameter length is little, and cutting knife volume is little.Adopt German import list interface, realize interface and once plug, constant product quality is good.By high-pressure overflow valve spinning to inner side, easy to use.Cutting expanded head part adopts internal thread to confine, and head is diminished, can stretch into narrower job space.Assembly of the parts simplified overhauling is convenient.
Accompanying drawing explanation
Fig. 1 is that small-sized single interface hydraulic shear expansion device opens schematic diagram.
Fig. 2 is the structural front view that small-sized single interface hydraulic shear expands device.
Fig. 3 is the structure side view that small-sized single interface hydraulic shear expands device.
In figure: the mono-interface reversing hand wheel of 1-; 2-cylinder cap; 3-oil cylinder; 4-hand handle; 5-piston; 6-connecting rod; 7-cutting knife; 8-bearing pin; 9-bidirectional hydraulic lock.
Detailed description of the invention
The small-sized single interface hydraulic shear of one as shown in the figure expands device, the piston rod front end axle of hydraulic jack connects two connecting rods, two connecting rod front ends are connected to the rear end of two cutting knifes, the middle part of two cutting knifes is connected on the bearing pin on the support of hydraulic jack front end jointly, there is hand handle support both sides, the cylinder cap of hydraulic jack rear end has bidirectional hydraulic lock, and cylinder cap rear end face connects single interface reversing hand wheel, and single interface reversing hand wheel rear end connects outer fuel feed pump; The head of two cutting knifes has expansion head, and there is serrated teeth the inner side of two cutting knifes.
Technical indicator:
Miniaturization, is convenient to small space and implements rescue.Be applicable to single interface pumping source connect; Adopt built-in type to leak overflow valve, make smaller volume.Single interface connects, and can with pressurely plug.Cutting expanded head part bearing pin is reduced to minimum.Assembly of the parts is simple and convenient.
Concrete technical scheme:
Reasonably reduce cylinder diameter length, reduce cutting knife volume, effectively reduce overall mass.
Adopt German import list interface, realize interface and once plug, improve the quality of products class and stability.
By high-pressure overflow valve spinning to inner side, reduced volume, and then weight reduction.
Cutting expanded head part adopts internal thread to confine, and head is diminished, can stretch into narrower job space.
