Surface is provided with external screw thread, and the pile is threaded on the lever seat, and radial direction of the pile along the pin is the same as described two
Root lever all aligns.When slotting lower margin is inserted into ground, a hole is bored on the ground, rotates pile to not interfering two levers with pin
Rotated for axle and be brought together into the state that can penetrate hole, lever seat is alignd with hole, by pushing away pile lever and shelves
To the depth needed in pole socket patchhole, rotating pile makes pile be drawn close towards lever, and pile inserts between two levers and same
When drive two levers using pin be axle rotate separate, separated result be lever with pile angle increase so that lever be stuck in
In hole, then base is set aside to and passes through connecting hole for position and the outer end of pile（In order to prevent base float, can be on ground
Nut is screwed on by base pressure holding on bottom surface in stake）.
Preferably, the lever is designed with cutting edge along two sides of lever rotation direction.Enable to drive lever to turn
It is laborsaving when moving and snapping into hole, namely lever is snapped onto in soil more conveniently.
Preferably, the lever is prismatic.It is easy to pile to insert between two levers.
The utility model tool has the advantage that：It can be tensioned to being tensioned in prefabricated bridge plate manufacturing process to cable wire
It is laborsaving during cable wire.
Brief description of the drawings
Fig. 1 is the schematic top plan view of the utility model embodiment one.
Fig. 2 is the schematic diagram of the slotting lower margin in embodiment two.
In figure：Lever seat 1, side plate 11, bottom plate 12, lever 2, pin 21, cutting edge 22, pile 4, nut 41, clamping joint 42, bottom
Seat 71, mounting hole 711, slide rail 72, pull bar 73, cable wire via 731, conical surface section 732, driving cylinder 74, conic clamp 75, clamping are logical
Hole 751, grip block 752, concrete pouring head 8.
Embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment one, referring to Fig. 1, a kind of device for the cable wire being tensioned in prefabricated bridge plate, including base 71, it is arranged at bottom
Two one slide rails 72, the pull bar 73 being slidably connected on slide rail and the driving cylinder 74 for driving pull bar to be slided on slide rail on seat.Bottom
Seat 71 is provided with mounting hole 711.Slide rail 72 extends in left-right direction.Pull bar 73 extends along the longitudinal direction.Pull bar 73 is provided with along slide rail
The cable wire via 731 of bearing of trend extension.The left end of cable wire via 731 is provided with conical surface section 732 and the taper coordinated with conical surface section
Dop 75.Conic clamp 75 is provided with the clamping through hole 751 axially extended.Conic clamp 75 is circumferentially divided by two pieces along conic clamp
The grip block 752 of cloth is stitched together composition.Two pieces of grip blocks 752 are encircled into clamping through hole 751.
In use, by being punched on cement floor, base 71 is fixed on ground through mounting hole 711 by setscrew
On face.The head of cable wire is set to be passed through from the framework of steel reinforcement on cement bridge plate mould for wearing the preset clearance of cable wire
After be then passed through after be then passed through cable wire via, then through in clamping through hole, conic clamp is inserted in conical surface section, then passes through driving
Cylinder pushes away towards a left side and so that pull bar slides on slide rail, is tensioned cable wire so as to realize.
Embodiment two, the difference with embodiment one are：
Referring to Fig. 2, wire rope tensioning mechanism is additionally provided with slotting lower margin.Inserting lower margin includes lever seat 1, lever 2 and pile 4.
Lever seat 1 includes two blocks of side plates 11 and one piece of bottom plate 12.Two blocks of side plates 11 and one piece of bottom plate 12 is u-shaped is connected to
Together.
Lever 2 has two.The middle part of two levers 2 is joined together by pin 21.The both ends of pin 21 are the same as two blocks of side plates 11
Link together.Lever 3 is prismatic.Lever 2 is designed with cutting edge 22 along two sides of lever rotation direction.
The surface of pile 4 is provided with external screw thread.Pile 4 is threaded on bottom plate 12 and runs through bottom plate 12.The axis of pile 4
It is in the same plane and vertical with the axis of pin 21.Nut 41 is threaded with pile 4.Nut 41 and lever 2 are distributed in
The both sides of bottom plate 12.The end of the one end of pile 4 away from lever is provided with prism forming head clamping joint 42.Clamping joint 42 is quadrangular
Shape.As long as clamping joint 42 is the prism of even number rib.
In use, boring a hole on dirt floor, nut 41 is removed, is arrived towards making the direction that pile 4 moves up rotate pile 4
Pile does not interfere two levers to turn to using pin as axle to be close together substantially and bearing of trend is the same as pile bearing of trend basic one
The position of cause, two levers 2 are that axle is turned to and is close together substantially and bearing of trend is basic with pile bearing of trend with pin 21
Unanimously（Can not fully come together between two levers does not have gap, and otherwise pile can not be inserted between two levers）, so
After make lever seat 1 with hole align, by push away in the lever 2 of pile 4 and the patchhole of lever seat 1 to needs depth, rotationally
Stake 4 makes pile be drawn close towards lever 2, and pile 4 is inserted between two levers and drives two levers to be rotated with pin 21 for axle simultaneously
And separate, separated result is that lever increases with the result of bolt so that lever is stuck in hole, then by base 71（Referring to Fig. 1）
On the ground shelved and connecting hole 711 is enclosed on the upper end of pile, then screws on nut 41 and locking nut is so as to realizing base
It is fixed on dirt floor wall.It is stuck on clamping joint 42 and is rotated by spanner when rotating pile 4.
