Detailed description of the invention
Embodiment 1:
As shown in Figure 1, 2, connect into tool anchor clamp by three intermediate plates 1, described guide groove is intermediate plate rear end one sunken arcs groove, rear end sidewall forms described block, sunken arcs groove connects into after moveable anchor at intermediate plate, minor diameter place forms recessed circular groove 3, and recessed circular groove rear end sidewall 4 forms described block, and the junction between recessed circular groove 3 and the intermediate plate front end conical surface arranges intermediate plate and holds groove 2 tightly.
Embodiment 2:
As shown in Figure 3,4, with the difference of embodiment 1 be that the rear end endoporus that is described intermediate plate 1 has step trough, described step trough connects into after moveable anchor at intermediate plate, form holddown spring carried out to the structure of spacing counterbore 5, when counterbore 5 is worked for carrying out spacing to the holddown spring being positioned in counterbore.
Embodiment 3:
As shown in Figure 5,6, there is boss the rear end that is described intermediate plate 1 with the difference of embodiment 1, described boss connects into after moveable anchor at intermediate plate, form holddown spring carried out to the structure of spacing circular bosses 6, when circular bosses 6 is worked for carrying out spacing to the holddown spring that is positioned over intermediate plate rear end.
Embodiment 4:
As shown in Figure 7,8, and the difference of embodiment 2 is that the intermediate plate external surface between intermediate plate guide groove and rear end is provided with sub-folder sheet and holds groove 7 tightly, can provide intermediate plate to hold groove 2 and intermediate plate pair tightly and hold 7 two positions of groove tightly and place elastic rings intermediate plate is held tightly, to meet the demand under different operating environment.
Embodiment 5:
As shown in Fig. 9,10, be only to retain sub-folder sheet to hold groove 7 tightly with the difference of embodiment 4, hold the interior rotation elastic ring of groove 7 tightly at sub-folder sheet and realize the object that intermediate plate is held tightly.
The present invention realizes an embodiment of automatic Tensioning work as shown in Figure 11,12,13,14:
Figure 11 is a kind of front card device, this device comprises top board 11, push rod 12, instrument anchor slab 13, fixed head 14, holddown spring 15, pressing plate 16, positioning bolt 17, wherein on fixed head 14, be provided with the stepped hole matching with the recessed circular groove rear end sidewall 4 of intermediate plate 1, pressing plate 16 use positioning bolts 17 are fastening with instrument anchor slab 13, intermediate plate 1 is the structure of embodiment 2, the counterbore of pressing plate 16 and intermediate plate connect into and between the counterbore after moveable anchor, are placed with holddown spring 15, holddown spring 15 is close to its maintenance for intermediate plate 1 being pushed up press all the time with the stepped hole of fixed head 11, form moveable anchor stretch-draw or the position of centering all the time while moving back anchor, be convenient to steel strand or exit steel strand, in the course of work, before described in Figure 11, clamp and be set to work assembly, all the time connect into the structure shown in Figure 11, can be not loose.
In jack, form the front clip type jack as shown in Figure 12 as the device of Figure 11 is installed on, taking the front clip type jack shown in Figure 11 as example illustrates operating principle of the present invention:
In position shown in Figure 12, top board 11 promotes push rod 12 and moves right, pushing tow fixed head 14 moves right, moveable anchor is transferred to from the hole of instrument anchor slab 13, now, can be by all steel strand from left to right respectively through roof hole 10, moveable anchor plate hole 9, intermediate plate hole 8, pressing plate and reserve the length of regulation.
In the stretching process shown in Figure 13, jack refuels and carries out stretch-draw, because piston 20 can not move.Oil cylinder 19 moves right, and overlaps 21 drive instrument anchor slabs 13 to move right steel strand are carried out to stretch-draw by punching, and now, baffle plate 18 separates with top board 11, and holddown spring 15 compresses intermediate plate 1 left, and intermediate plate 1 is held steel strand tightly steel strand are carried out to stretch-draw.
Moving back in anchor process shown in Figure 14, oil cylinder 19 moves back left after anchor joins with top board 11 again to baffle plate 18, because oil cylinder 19 continues to be moved to the left, overlapping 21 by punching drives instrument anchor slab 13 to be moved to the left, now, because top board 11 withstands baffle plate 18, top board 1, push rod 12, fixed head 14 are fastening integrative-structure, therefore, and when fixed head 14 moves to the recessed circular groove of intermediate plate 1 rear end sidewall 4, the position of intermediate plate 1 is limited, make intermediate plate 1 translation again, along with oil cylinder 19 continues retraction, intermediate plate 1 is transferred to, unclamp steel strand, realize and move back anchor.
After oil cylinder retraction puts in place, under the elastic force acting in conjunction by the step groove of fixed head 14, holddown spring 15, three intermediate plates 1 also continue the shape of maintenance centering, and the work of stretch-draw next time can be provided, and whole process is without manually intermediate plate being dismantled or installed.
