Abstract
A kind of small-sized single joint expander, both sides, hydraulic jack front end respectively axle connect a connecting rod, connecting rod other end axle connects the outside portion of the bottom of thin trapezoidal expansion arm, the inside portion axle of the bottom of two expansion arm is connected on the shaft coupling of the outer end of piston rod, expansion head is equipped with on the top of expansion arm, has large sawtooth outside expansion head; Oil cylinder rear end connects bidirectional hydraulic lock, and the bidirectional hydraulic lock other end connects single interface reversing hand wheel, the external fuel feed pump of single interface reversing hand wheel other end; Outside hydraulic jack, carrying handle is housed.This installation weight is light, and easy to carry, weight is less than 10kg; Specified expansion distance is large: 500mm, and expansionary force is large: 35kN.Be adapted to maneuverability and enter rescue site, improve rescue efficiency.Bidirectional hydraulic lock has auto-lock function, and expander is not bounced back in any expanded position, easy to use; Assembly of the parts is simple, easy to maintenance.
Description
Technical field
The utility model belongs to the break-in tool that rescue uses, the particularly small-sized single joint expander of one.
Background technology
Rescuing dismounting instrument, is applied to car accident, house collapse, scene of fire, or in the natural calamity such as earthquake, for tearing accident vehicle surface steel plate, mobile and lifting barrier, pries open gap and be extended for passage.For fire brigade, People's Armed Police, highway fast reaction rescue group.The hydraulic spreader that hydraulic power is provided by external connection power source that existing market is sold, 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 joint expander.Lightweight, expansionary force is large, uses flexible and convenient operation, adapts to rescue site orcible entry and uses.
The technical solution of the utility model is:
A kind of small-sized single joint expander, it is characterized in that: both sides, hydraulic jack front end respectively axle connect a connecting rod, connecting rod other end axle connects the outside portion of the bottom of thin trapezoidal expansion arm, the inside portion axle of the bottom of two expansion arm is connected on the shaft coupling of the outer end of piston rod, expansion head is equipped with on the top of expansion arm, has large sawtooth outside expansion head; Oil cylinder rear end connects bidirectional hydraulic lock, and the bidirectional hydraulic lock other end connects single interface reversing hand wheel, the external fuel feed pump of single interface reversing hand wheel other end; Outside hydraulic jack, carrying handle is housed.
The utility model effect is:
Lightweight, portable convenient, weight is less than 10kg; Specified expansion distance is large: 500mm, and expansionary force is large: 35kN.Be adapted to maneuverability and enter rescue site, improve rescue efficiency.Bidirectional hydraulic lock has auto-lock function, and expander is not bounced back in any expanded position, easy to use; Assembly of the parts is simple, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the expansion state figure of small-sized single joint expander
Fig. 2 is the closure state figure of small-sized single joint expander
In figure: the mono-interface reversing hand wheel of 1-; 2-bidirectional hydraulic lock; 3-oil cylinder; 4-piston; 5-connecting rod; 6-shaft coupling; 7-expansion arm; 8-expands head; 9-carrying handle.
Detailed description of the invention
The small-sized single joint expander of one as shown in the figure, both sides, hydraulic jack front end respectively axle connect a connecting rod, connecting rod other end axle connects the outside portion of the bottom of thin trapezoidal expansion arm, the inside portion axle of the bottom of two expansion arm is connected on the shaft coupling of the outer end of piston rod, expansion head is equipped with on the top of expansion arm, has large sawtooth outside expansion head; Oil cylinder rear end connects bidirectional hydraulic lock, and the bidirectional hydraulic lock other end connects single interface reversing hand wheel, the external fuel feed pump of single interface reversing hand wheel other end; Outside hydraulic jack, carrying handle is housed.
By hydraulic power unit (other product) to expander list interface fuel feeding, expander is under the control of reversing hand wheel and bidirectional hydraulic lock, and hydraulic oil promotes piston, and piston rod interlock shaft coupling pulls connecting rod, make expansion arm close or open, realize expansion and holding function with this.
Technical indicator:
Miniaturization, is convenient to small space and implements rescue.Be applicable to single interface pumping source connect, can with pressurely plug; Adopt built-in type to leak overflow valve, make smaller volume.Specified expansionary force reaches 30kN, and extended distance reaches 500mm.Bidirectional hydraulic lock has auto-lock function, and expander is not bounced back in any expanded position; Assembly of the parts is simple and convenient.
Concrete technical scheme:
Expansion arm is driven to realize expansion or holding function by piston rod by shaft coupling and connecting rod; Large loculus overflow is on oil cylinder rear end face, axial arranged, to reduce cylinder body radial dimension; Oil cylinder, piston and expansion arm material all adopt high-strength light alloy material, make the more lightweight of whole instrument; Adopt German import list interface, realize interface and once plug, improve the quality of products class and stability.
