Description
Technical field
The present invention relates to pre-stressed bridge pulling test devices, and in particular to a kind of moveable anchor dress for facilitating steel strand wires to penetrate
It sets.
Background technique
The jack that traditional prestressed bridge girder tensioning uses is centre-hole jack, at work, steel strand wires, work anchor
With work clip sheet after the completion of tensioning, it will be encapsulated in prestressed component；Steel strand wires beyond work clip sheet before packaging, will
5~10mm is stayed except work clip sheet, remaining be removed, be removed the steel strand wires to get off be treated as steel scrap processing, one
Entire engineering waste steel strand wires are completed up to more than 100 ten thousand yuan in railway beam field.
In order to reduce the waste of steel strand wires, each tensioning equipment supplier proposes a variety of tensioning for saving the pre- allowance of steel strand wires
Jack version (preceding clip jack), having a common feature in all schemes is exactly to fall into moveable anchor and tool clamping piece
To inside jack, the spacing between work anchor to moveable anchor is reduced, to realize the effect for reducing the pre- allowance of steel strand wires.
But whether tensioning is generally determined by the elongation of control stretching force and steel strand wires during prestressed stretch-draw
It meets the requirements.By detection jack calibration when traditional stretching force measures, oil pressure converting to force is subjected to stretching force control, and steel
The elongation of steel strand wires is determined when twisted wire elongation by detecting the difference of the overhang of jack piston and the amount of recovery of tool clamping piece
Amount.Obviously moveable anchor and tool clamping piece are trapped in the way inside jack, will be unable to the amount of recovery for detecting tool clamping piece.
Since the testing requirements of detection and steel strand wires elongation to above-mentioned stretching force are not high in highway prestressed stretch-draw,
So current some preceding clip jack are still widely used.But due to railway prestressed stretch-draw, especially high-speed rail
In construction, stretching force is detected and controlled, and the detection of steel strand wires elongation is required higher.Therefore, railway at present
In prestressed stretch-draw in the case where no solution detection instrument intermediate plate amount of recovery, it is necessary to use traditional stretch-draw jack.It is right
In the inaccurate use of preceding clip jack that those cannot detect intermediate plate amount of recovery.In addition, due to the survey with oil pressure detection stretching force
Power scheme, also due to error is larger (0.5%~1.0%) in use, also starting regulation in railway tensioning must be passed with dynamometry
The detection of sensor progress stretching force.
Based on above-mentioned requirements, railway intelligent tensioning equipment is to increase a dynamometry between jack and lengthening set at present
Sensor, for detecting stretching force.The pre- allowance for obviously increasing steel strand wires again in this way, causes steel strand wires more to waste.
In order to save steel strand wires, many people are to a kind of new structure of the Curve guide impeller of traditional centre-hole jack ---
Fore-clamp (card) formula jack.According to the difference of the installation site of the moveable anchor clamping device of clip jack before current can will before
Clip jack is divided into two classes, and one kind is that moveable anchor clamping device is installed on cylinder body, and another kind of is preceding clip clamping device peace
On rear stopper rod.
Clamping device is placed to above inner cylinder, and load cell is installed on piston rod, and this structure mainly has two
A drawback, one is piston rod can prolong axial movement and circumferential rotation is broken so as to cause the cable of load cell by strand,
Second is that being that cylinder body inner cylinder only has oil pressure load originally, and increases and prolong axial pulling force, and force way causes front end to have
Very big stress is concentrated.
Preceding clip clamping device is installed to above piston rod can save steel strand wires well, and adapt to the rotation of steel strand wires
Turning problem --- clamping device is rotated together with piston.
Be in above scheme using oil pressure detect stretching force, while also can not detection instrument intermediate plate amount of recovery.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of preceding clip moveable anchor devices, can detecte tool clamping piece
Amount of recovery.
The technical scheme to solve the above technical problems is that a kind of tool anchor device for facilitating steel strand wires to penetrate,
Including moveable anchor disk, pushes back plate, preceding pushing sleeve, tool clamping piece, pushback pin, is pushed forward spring, spring bearer plate and amount of recovery feeler lever；It is described
Moveable anchor disk is equipped with through-hole, and the tool clamping piece is mounted in the through-hole, and is located at the middle part of the through-hole；The spring
Pressing plate is fixedly mounted on the rear end of the moveable anchor disk, and one end of the preceding pushing sleeve through the spring bearer plate and is located at described logical
The rear portion in hole, and opposite with one end of the tool clamping piece, the other end of the preceding pushing sleeve be located at the through-hole it is outer and with it is described
Amount of recovery feeler lever is connected；It is described to be pushed forward spring pocket and be located on the one end at the through-hole rear portion mounted in the preceding pushing sleeve, and it is described before
One end and the spring bearer plate for pushing away spring are inconsistent；The front end for pushing back plate and being located at the moveable anchor disk, the pushback pin
One end be located at the front of the through-hole, and opposite with the other end of the tool clamping piece, the other end of the pushback pin is located at
Outside the through-hole, and it is connected to described push back on plate；It is described to push back plate, the pushback pin, the tool clamping piece, the preceding pushing sleeve
The steel strand wires through-hole that passes through for steel strand wires is equipped with along axis on the amount of recovery feeler lever.
The beneficial effects of the present invention are: when using a kind of tool anchor device for facilitating steel strand wires to penetrate of the invention, very heavy
Top drives during returning back to top pushes back plate retrogressing, pushes back the dynamic pushback pin of strip and retreats, pushback pin pushes tool clamping piece to open its front end
Angle is magnified, and preceding pushing sleeve withstands tool clamping piece rear end under the action of being pushed forward spring, magnifies its rear end angle of release, conveniently penetrates steel strand
Line；Steel strand wires after pushing back plate tapping and putting on along steel strand wires through-hole, when tensioning very heavy ejection top, push back plate advance, tool
Intermediate plate clamps steel strand wires；Amount of recovery feeler lever and preceding pushing sleeve follow tool clamping piece to move forward and backward together, can be with real-time detection tool holder
Piece advance, backway.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the front size of the through-hole is less than the rear size of the through-hole, and the tool clamping piece is by three pieces point
From intermediate plate composition frustum cone structure, and the variable steel strand wires through-hole of diameter is formed on the axis of rotary table.
Beneficial effect using above-mentioned further scheme is: the rotary table knot that tool clamping piece is made of the intermediate plate that three pieces separate
Structure, and the variable steel strand wires through-hole of diameter is formed on the axis of rotary table, facilitate steel strand wires to penetrate.
Further, the pushback pin, which is located at one end outside the through-hole and is connected to by connecting plate and conduit, described pushes back plate
On；The connecting plate be located at the moveable anchor disk and it is described push back between plate, the pushback pin is located at one end outside the through-hole
Be connected on the connecting plate, the both ends of the conduit be connected to the connecting plate and it is described push back on plate, the conduit
