The utility model mainly comprises a two-armed support, a reinforcing steel tool anchor, and a locking anchor device, wherein, an axial-opening cone groove is arranged in the center of the top end of the two-armed support, two liquid cylinders are extended on both sides on the right end of the two-armed support, and two clamping jaws of the reinforcing steel tool anchor and the inner cone groove of the two-armed support are matched to tightly wedge in; two small liquid cylinders are arranged on both sides in an axial-opening frame of the locking anchor device, two pistons which are matched with the two liquid cylinders of the two-armed support are extended on the right end of the locking anchor device, and small pistons which are matched with the two small liquid cylinders are extended on the right end of an axial-opening top anchor pipe. Thereby, the utility model has the advantages of easy assembling, easy demounting, stable stretching, and reliable stretching.
Description
The utility model relates to a kind of tension reinforcing steel bar utensil, is particularly suited for bearing the stretch-draw utensil of heavy duty, large-span prestressed structure reinforcing bars.
At present, traditional tension reinforcing steel bar instrument is a single cylinder jack mechanism, and it need vertically wear reinforcing bar, loads and unloads pretty troublesomely, and stretch-draw clamping and break adrift are all stable inadequately.
In view of this, the purpose of this utility model provides a kind of opening stretch-draw jack, can be from the radially direct clamping reinforcing bar of reinforcing bar, and can finish fast and clamp stretch-draw and break adrift reinforcing bar one termination.
The purpose of this utility model is achieved in that it mainly comprises two-arm yoke, reinforcing bar moveable anchor and anchoring device, wherein be provided with the female cone groove of axially open in the middle of the two-arm yoke top, and the right-hand member both sides are stretched out two fluid cylinders respectively, the outer conical surface of two jaws of reinforcing bar moveable anchor cooperates wedging with the female cone groove of two-arm yoke, anchoring device comprises axial direction opening frame and axially open top anchor tube, wherein the axially open both sides of axial direction opening frame are respectively equipped with two small liquid jars, stretch out the two-piston of sliding fit in two-arm yoke two fluid cylinders respectively in these axial direction opening frame right-hand member both sides again, the axially open both sides right-hand member of axially open top anchor tube stretches out the valve piston in two small liquid jars of sliding fit in axial direction opening frame respectively.
Above-mentioned two fluid cylinders are communicated with being communicated with oil pipe.
Above-mentioned two small liquid jars are communicated with being communicated with oil pipe.
Owing to adopt such scheme: easy to loading and unloading, stretch-draw is reliable and stable, work efficiency improves greatly.
Below in conjunction with drawings and Examples the utility model is further specified.
The horizontal scheme drawing of Fig. 1 the utility model exemplary embodiments.
Among the figure: 1, two-arm yoke 11, female cone groove 12, fluid cylinder 13, connection oil pipe 14, guide rail bracket 2, reinforcing bar moveable anchor 21, jaw 22, slide block 23, coil spring 3, anchoring device 31, axial direction opening frame 311, small liquid jar 312, connection oil pipe 313, piston 32, axially open top anchor tube 321, valve piston 4, anchor ring 5, anchor sheet 6, reinforcing bar
Present embodiment comprises two-arm yoke 1, reinforcing bar moveable anchor 2 and anchoring device 3, as shown in Figure 1, and wherein:
The centre on two-arm yoke 1 top is provided with the female cone groove 11 of axially open, and the right-hand member both sides are stretched out two fluid cylinders 12 respectively, and these two fluid cylinders, 12 usefulness are communicated with and are connected with a Hydraulic Pump (not shown) after oil pipe 13 is communicated with, and also stretch out a guide rail bracket 14 in addition in the middle of its right-hand member.
Reinforcing bar moveable anchor 2 mainly comprises two jaws 21, slide block 22 and coil spring 23, wherein:
Jaw 21 outer rims are that outer conical surface, inner edge are the faces of cylinder (about 170 ° of inner edges) with many radial slot, and two jaws 21 match with the female cone groove 11 of two-arm yoke 1 with outer conical surface, and the top forms a v-notch (inserting for reinforcing bar 6).
Anchoring device 3 mainly is to be made of axial direction opening frame 31 and axially open top anchor tube 32, wherein:
The axially open both sides of axial direction opening frame 31 are respectively equipped with two small liquid jars 311 and with after being communicated with oil pipe 312 and being interconnected, be connected with another Hydraulic Pump (not shown), stretch out respectively in the right-hand member both sides of this axial direction opening frame 31 again two-piston 313 and with two fluid cylinders, 12 sliding fits of two-arm yoke 1.
The axially open both sides right-hand member of axially open top anchor tube 32 be respectively equipped with two valve pistons 321 and with axial direction opening frame 31 in two small liquid jars, 311 sliding fits; The left end of this axially open top anchor tube 32 is against the stub end of three anchor sheets 5 again, and the male cone (strobilus masculinus) of this anchor sheet 5 is engaged in the anchor ring 4, and supports and clamp reinforcing bar 6 one terminations with the face of cylinder of many radial slot.
The principle of work of present embodiment is as follows:
When the jaw 21 of reinforcing bar moveable anchor promotes under the compressing of slide blocks 22 at coil spring 23, wedging is on two-arm yoke 1 and clamp within it reinforcing bar 6, start a Hydraulic Pump (not shown) then, pressure oil enters two fluid cylinders 12 through being communicated with oil pipe 13, two-arm yoke 1 move right (piston 313 maintains static) just tension reinforcing steel bar 6 till becoming needed prestressing tendon; Restart another Hydraulic Pump (not shown), pressure oil enters two small liquid jars 311 through being communicated with oil pipe 312, promotes valve piston 321, and axially open top anchor tube 32 is moved to the left, compress 5 wedgings of three anchor sheets and in anchor ring 4 and mutually, lock, simultaneously anchor sheet 5 clamping reinforcing bars 6 one terminations; At last, radially can directly unload anchoring device 3, reinforcing bar moveable anchor 2 and two-arm yoke 1 from reinforcing bar 6.
