Description
Technical field
The present invention relates to a kind of device of drawing steel stranded wire, belong to infrastructural project equipment technical field.
Background technology
Presstressed reinforcing steel is widely used in existing prestressed reinforced concrete construction or geotechnical engineering structure, presstressed reinforcing steel is generally all
It is single use, and is retained in concrete or rock-soil layer using after complete（Its length can reach 20-30 meters）.Such one
Come, not only waste of materials, also constructs to form obstacle, it is necessary to reclaim presstressed reinforcing steel to close to buildings.
In order to realize that steel strand wires are reclaimed, a kind of automatic drawing of the Patent No. ZL201120317074.X of applicant's application
The jack of steel strand wires, when the device clamps steel strand wires by movable clamping part, stationary gripping part unclamps steel strand wires, and piston can be
It is displaced outwardly driving movable clamping part in oil cylinder by the outside drawing of steel strand wires；It is solid that movable clamping part pulls steel strand wires to move adjacent to
When determining clamping part and stopping moving out, and movable clamping part unclamps steel strand wires and it is accurate that its initial position is inwardly moved to piston
The standby drawing for carrying out next step, it is constantly automatic to repeat above-mentioned two step, go round and begin again, so as to the automatic of steel strand wires can be realized
Drawing.
But, being found in applicant's practice of construction use, the device has problems with：1）The device needs anchor cable to expose 1
Rice is long, can just meet initial automatic extraction and require, but, the anchor cable in construction exposes not same, and anchor cable exposes ratio often
It is shorter and smaller, meanwhile, the device is an integral product, is weighed very much, and field worker movement is inconvenient；2）The fixation of the device is automatically controlled
Device and movable electric control gear can control stationary gripping part and movable clamping part to clamp or unclamp steel strand wires by console so that whole
The complex structure of individual device, it is unreliable to work.
The content of the invention
The technical problem to be solved in the present invention is directed to prior art deficiency, proposes that a kind of convenient scene is artificial and operates and suitable
Conjunction exposes the short jack of anchor cable.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of jack for drawing steel stranded wire,
Including oil cylinder and support, the oil cylinder include be provided with base cylinder barrel, cylinder barrel is separated into the chamber of oil-feed oil return two piston and
Piston rod, the piston is fixed on one end of the piston rod, and the piston rod is formed with first through hole, the base along its axial direction
On be formed with the second through hole, the piston rod is stretched out between the other end of cylinder barrel and the support and is mutually interconnected by fast assembling disassembling structure
Fixation is connect, the cylinder barrel can be driven to be moved forward along the piston or rear shifting when the oil-feed, oil return chamber oil inlet and oil return；On the base
Sleeve pipe is fixed with, described sleeve pipe one end is inserted and sealing is formed in second through hole, described sleeve pipe other end insertion described first
Formed in through hole and be slidably matched and sealed against one another, the first through hole, sleeve pipe and the second through hole are interconnected；On the support and
Forward and backward instrument anchor is respectively fixed with sleeve pipe；When the cylinder barrel moves forward, the preceding instrument anchor clamps the steel strand wires,
Simultaneously described rear instrument anchor unclamps the steel strand wires；When being moved after the cylinder barrel, the preceding instrument anchor unclamps the steel and twists
Line, while the rear instrument anchor clamps the steel strand wires.The present invention is using the effect of above-mentioned technical proposal：1）The present invention will
Oil cylinder and support are made as independent two parts, are resisted against on pile body by by support, and support and piston rod stretch out the another of cylinder barrel
It is interconnected and fixed by fast assembling disassembling structure between end, can so mitigates the monomer weight that workman carries every time so that work
People can carry out convenient manual operations with scene；Simultaneously, it is possible to reduce the volume of whole device, anchor cable was needed to expose 1 meter originally
It is long, now only need anchor cable and expose that 30cm is long can just to meet requirement, the need for having adapted to site operation；2）By in support
Forward and backward instrument anchor is respectively fixed with upper and sleeve pipe, when using, steel strand wires forward and backward instrument anchor is sequentially passed through into, in cylinder barrel
During reach（Moved near holder orientation）, preceding instrument anchor clamps steel strand wires, while rear instrument anchor unclamps steel strand wires；In cylinder
When being moved after cylinder（Moved to away from holder orientation）, preceding instrument anchor unclamps steel strand wires, while rear instrument anchor clamping steel strand wires, can
So that quickly and easily steel strand wires are carried out with drawing, the simple structure of whole device, reliable operation.
The improvement of above-mentioned technical proposal is：Edge is fixed with the cylinder barrel length direction parallel cantilever and leads on the support
Post, interval is fixed with two front-rear switch for control cylinder commutation on the guide pillar, is fixed with positioned at preceding on the cylinder barrel
In the middle of switching afterwards and for the movable Y type blocks to touch front-rear switch respectively of cylinder barrel, the guide pillar to be in Y type blocks
It is horizontally-arranged in Y types opening.
The present invention is using the effect of above-mentioned technical proposal：Two are fixed with for control cylinder by the interval on guide pillar
The front-rear switch of commutation, after cylinder barrel moves to setting position, by the Y reliable touching switch of type block, and then can pass through
Switch and the oil inlet and oil return of oil cylinder is commutated.
The one of perfect of above-mentioned technical proposal be：The forward and backward instrument anchor includes the substrate and spring that are oppositely arranged
