Abstract
The utility model discloses a hydraulic bender for reinforcing bars, which is used for the reinforcing cage of reinforced concrete. The hydraulic bender for reinforcing bars is especially suitable for the site operation that a bend hook with an angle of 135 needs to be carried out to a reinforcing steel stirrup of tall buildings. The hydraulic bender for reinforcing bars is composed of a bend hook working head and a pumping station which is form from the connection of a hydraulic valve, a hydraulic pump, a hydraulic oil tank, etc. The utility model has the advantages of light weight, small size, and convenient operation. The hydraulic bender for reinforcing bars is in particular suitable for the arranged reinforcing cage, and the end of the opening of a stirrup forms an oblique bend hook with an angle of 135 DEG; the hydraulic bender for reinforcing bars which has the actions that a straight bend hook with an angle of 90 DEG can not stabilize the reinforcing cage and can not improve the anti-shock performance can meet the requirements of high-rise buildings and the buildings in the anti-shock areas.
Description
The utility model relates to building machinery, is used for the crotch of the reinforced concrete prefabricated steel wire binding bar of building trade, particularly curved 135 ° of tilted hump hooks.
Existing stirrup bender (special use) can be done 90 ° of straight bending and can not bend 135 ° of tilted hump hooks steel bar end.The volume of its equipment is big, Heavy Weight, and inconvenience is moved easily, so the buckling work of reinforcing bar can only carry out on ground; Can not adapt to and require the stirrup end to make the needs of 135 ° of tilted hump hooks in skyscraper and the anti-seismic structure.But the muscle hoop on coupled columns or the beam has only the stirrup that adopts general 90 °/90 ° (seeing Fig. 1 b) straight crotch, just is inserted in easily in the main muscle of post (or beam); If the end of stirrup be inserted in post (or beam) be processed into before 135 °/135 ° tilted hump hooks (see Fig. 1 a) then again inconvenience be inserted in the main muscle of post (or beam), bring difficulty to construction.
The purpose of this utility model, be to provide the site operation instrument of the curved 135 ° of angle stirrup hooks of a kind of energy, after the stirrup that is about to 90 °/90 ° of straight crotches of normal tape is inserted in the main muscle of post (or beam), use the tilted hump hook that hoop bends to 135 ° of leading that this device can center on the end of stirrup stirrup corner, to increase the fixation of stirrup, prevent the framework of steel reinforcement deflection, satisfy the requirement of skyscraper and anti-seismic structure.
The utility model is achieved in that
On the fuselage of crotch working head hydraulic cylinder is housed, the piston in hydraulic cylinder club head has a pin, constitute the slide block mechanism that to swing with the sliding tray on the movable elbow, movable elbow is equivalent to fork, can be around the axle swing that is fixed on the fuselage, therefore, when piston rod moves back and forth, movable elbow will be swung around axle, and the fixedly elbow of two symmetric arrangement also is housed on the fuselage, two fixedly the spacing in the elbow adapt with the stirrup that is bent.After feeding pressure oil in the hydraulic cylinder, piston rod is outwards passed, make movable elbow to fixedly elbow direction swing by pin and sliding tray, because movable elbow contacts (holding) with the end of stirrup opening, and fixedly elbow blocks the main hoop of stirrup corner, so can make the main muscle bending of stirrup end in post (or beam), form 135 ° of tilted hump hooks.
On the working head fuselage handle is housed, electric controling switch is housed on the handle,, carry and control the action of movable elbow so that handle.Be associated with high-pressure oil pipe and control cable between working head and the hydraulic power unit.Below in conjunction with accompanying drawing working condition of the present utility model is illustrated:
Fig. 1 is the form of steel wire binding bar terminal hook, and Fig. 1 a is 135 °/135 ° formulas, and Fig. 1 b is 90 °/90 ° formulas:
Fig. 2,3 is the utility model working head structure and work schematic diagram;
Fig. 4 is for using the framework of steel reinforcement process figure of the utility model coupled columns;
Fig. 5 is a hydraulic system schematic diagram of the present utility model.
Be contained in the control of electromagnet ICT (20) suspension control switch (13) on the solenoid directional control valve (17).Before gauge tap (13) pressing, magnetic valve (17) is in shown position (meta), the oil of discharging from hydraulic pump (15) directly flows back to fuel tank (21) by overflow valve (18), the plunger shaft of hydraulic cylinder this moment (1) does not have pressure oil to enter, and movable elbow (7) is failure to actuate.When working head of the present utility model partly enters the gauge tap (13) on pressing (opening) handle (12) behind crooked stirrup (6) station, make magnetic valve (17), commutation is to right position, oil process magnetic valve (17), hydraulic control one-way valve (19) from hydraulic pump (15) is discharged enter hydraulic cylinder (1).The interior oil pressure of hydraulic cylinder (1) raises, piston (2) will overcome the counter-force of spring (3) and the yield force of stirrup (6), and piston rod (11) is outwards passed, and go up pin (10) in the sliding tray, movable elbow (7) is swung clockwise around axle (8) by the movable elbow (7) that is embedded in of piston rod (11) head, and then the end that makes stirrup (6) is bent to 135 ° of crotches by 90 ° of crotches under its effect, and a side of movable elbow (7) will be run into fuselage (8) and limited subsequently.Hydraulic cylinder (1) pressure continues to rise; the overflow valve (14) that then plays the safeguard protection effect open since movable elbow (7) limited after; the interior oil pressure of hydraulic cylinder (1) continues to rise, and pressing (cutting out) gauge tap (13) makes magnetic valve (17) outage get back to meta.During hydraulic cylinder (1) oil return.The outlet pressure of hydraulic pump (15) is set by overflow valve (18), oil from hydraulic pump (15) discharge, a part flows into fuel tank (21) from overflow valve (18), a part enters the control chamber of hydraulic control one-way valve (19), make hydraulic control one-way valve (19) reverse opening, the pressure oil in the hydraulic cylinder (1) flows back to fuel tank (21) through hydraulic control one-way valve (19), magnetic valve (17) and choke valve (16).The effect of choke valve (16) is after eliminating hydraulic cylinder (1) release, spring (3) forces piston (2) reposition, drive inwardly withdrawal of piston rod (11), at this moment owing to the pin (10) that is fixed on the piston rod (11) is embedded in the sliding tray of movable elbow (7), cause pin (10) to drive movable elbow (7) and rotate, get back to the position when starting working around bearing pin (8) counterclockwise.Movable elbow (7) opens again.Can carry out next work cycle again.
The utility model can be constructed at the concrete reinforcement framework that frame is good, realizes 135 °/135 ° tilted hump hooks of stirrup end, satisfies the requirement of skyscraper and anti-seismic structure, has that structure is new, volume is little, in light weight a, advantage such as efficient is high, and is easy to operate.
