In use, passing through mounting hole 711 for wire rope tensioning mechanism 7 by setscrew by punching on cement floor It is fixed.Concrete prefabricated bridge plate production mold is located between wire rope tensioning mechanism and cable wire volume support frame.The mistake of tensioned cable Journey are as follows: cable wire volume is arranged and is fixed in shaft 53 and is fixed on cable wire volume support frame, makes the head of cable wire from positioned at water The preset clearance that framework of steel reinforcement on mud bridge plate molding die is used to wear cable wire is then passed through cable wire via hole after being then passed through after passing through, Then through clamping in through-hole, conic clamp is inserted into conical surface section, then is pushed away towards a left side so that pull rod is in sliding rail by driving cylinder Cable wire is tensioned by upper sliding to realize.
Embodiment two, with the difference of embodiment one are as follows:
Referring to fig. 2, wire rope tensioning mechanism is additionally provided with slotting lower margin.Slotting lower margin includes lever seat 1, lever 2 and ground 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 It links together.Lever 2 is prismatic.Lever 2 is designed with cutting edge 22 along the two sides of lever rotation direction.Two levers 2 are distinguished For the first lever 2-1 and the second lever 2-2.First lever 2-1 includes interlude 2-11 and two end 2-12.Interlude 2-11 Both ends be designed with along pin 21 circumferentially extend and run through interlude through-hole 2-111.Two end faces of interlude 2-11 are designed with Jack 2-112.Jack 2-112 is connected to the through-hole 2-111 for being located at the same end with jack.One end of end 2-12 is equipped with slide bar 2- 121, the other end is equipped with tip 2-122.Two end 2-12 are plugged on interlude 2-11 two by slide bar 2-121 correspondingly The both ends of section 2-11 are connected between in the jack 2-112 at end.The inner end of slide bar 2-121 is located in through-hole 2-111.Second lever 2-2 is set there are two jacking block 2-21.Jacking block close to pin one end end face 2-211 and through-hole close to pin one end end face through-hole 2-1111 Positioned at it is same with shaft 21 on the cylindrical surface of axis.Jacking block 2-21 is along the radial width of pin 21 from free end 2-212 to connecting pin 2-213 becomes larger.
The surface of ground pile 4 is equipped with external screw thread.Ground pile 4 is threaded on bottom plate 12 and through bottom plate 12.The axis of ground pile 4 It is in the same plane and vertical with the axis of pin 21.Nut 41 is threaded on ground pile 4.Nut 41 and lever 2 are distributed in The two sides of bottom plate 12.The end of the one end of ground pile 4 far from lever is equipped 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.
Referring to Fig. 3, the evacuation gap 2-22 passed through for the first lever 2-1 is formed between jacking block 2-21 and the second lever 2-2. Through-hole 2-111 and jacking block 2-21 is located in the same plane perpendicular to pin 21.Circumferential direction of the through-hole 2-111 and jacking block 2-21 along pin 21 Alignment.
Referring to figs. 2 and 3, in use, boring a hole on dirt floor, nut 41 is removed, towards the side for moving up ground pile 4 Do not interfere to ground pile two levers to turn to using pin as axis to rotation ground pile 4 to be close together substantially and extending direction prolongs with ground pile Stretch the almost the same position in direction, two levers 2 are that axis is turned to and is close together substantially and the same ground pile of extending direction with pin 21 Extending direction is almost the same, and (can not fully come together between two levers does not have gap, and otherwise ground pile can not be inserted into two Between lever), it is aligned lever seat 1 with hole, makes lever 2 and lever seat 1 insert in the hole and arrive needs by pushing away ground pile 4 Depth, rotation ground pile 4 draw close ground pile towards lever 2, and ground pile 4 is inserted between two levers and drives two levers with pin simultaneously 21 is axis rotates and separates, and separated result is that lever increases with the result of bolt so that lever is stuck in hole, then by pedestal 71(is referring to Fig. 1) on the ground shelved and 711 sets of the connecting hole upper ends in ground pile, then screw on nut 41 and locking nut to Pedestal is fixed on dirt floor wall by realization.It is to be stuck on clamping joint 42 to be rotated by spanner when rotating ground pile 4.When Ground pile 4 drive the first lever 2-1 and the second lever 2-2 rotation and separate during, jacking block 2-21 is inserted into through-hole 2-111 Depth gradually deepen, jacking block far from the end face 2-214 of pin abut to slide bar 2-121 to through end 2-12 from interlude 2-11 Interior ejection (namely making the first lever 2-1 elongated), to play the role of improving snap effect.
Embodiment three, with the difference of embodiment two are as follows:
Referring to fig. 4, ground pile 4 is rotatably connected to the snap ring 43 along ground pile circumferentially extending.Snap ring 43 passes through two stainless steel steel Silk 44 correspondingly links together two levers 2.The program can be by deviating from 4 post-tensioning stainless steel steel wire 44 of ground pile The rotation of two levers 2 is driven to be closed up and horizontal, to take out from hole.
