Abstract
The utility model relates to a steel bar truss forming machine, in particular to a steel bar retrogression prevention mechanism for a steel bar truss forming machine. The steel bar retrogression prevention mechanism comprises a pair of feed rollers (1) installed on a feeding port of the steel bar truss forming machine; and the feed rollers adopt one-way wheels which only can enable a steel bar (2) to move from back to front. With the adoption of the mechanism, produced steel bar trusses can be ensured to have the same specifications.
Description
Technical field
The utility model relates to a kind of steel bar girder make-up machine, relate in particular to a kind of be used for the steel bar girder make-up machine prevent the reinforcing bar backward gear.
Background technology
Current; With the steel bar girder make-up machine produce steel bar girder reinforcing bar from the process that the biscuit state pulls out because reinforcing bar still is not very firm after being folded into the truss shape, but the reinforcing bar of biscuit state has certain counter pull on the contrary; The reinforcing bar that so just causes easily having pulled out is retracted by counter; Setback takes place, and again because do not got back to the steel bar girder height and position of original setting by the anti-reinforcing bar that retracts, thereby has caused diversified in specifications the causing of steel bar girder of producing.
Summary of the invention
The utility model technical problem to be solved is: provide steel bar girder specification that a kind of assurance produces consistent be used for the steel bar girder make-up machine prevent the reinforcing bar backward gear.
The technical scheme that the utility model adopted is: a kind of be used for the steel bar girder make-up machine prevent the reinforcing bar backward gear; It comprises a pair of charging roller that is installed on the steel bar girder make-up machine charging aperture, said charging roller adopt make reinforcing bar can only from after the one-way wheel that moves forward.
Adopt after the above structure compared with prior art; The utlity model has following advantage: adopted this anti-retrogression mechanism; Produce steel bar girder reinforcing bar when the biscuit state is pulled out; Reinforcing bar on the production line can be not again be retracted by the reinforcing bar of biscuit state is counter, promptly setback can not take place, and can guarantee that like this steel bar girder specification of producing is consistent.
As preferably, described being installed on the steel bar girder make-up machine charging aperture is meant that it also comprises a support post, and described a pair of charging roller is installed on the support post through support arm.Design can let a pair of charging roller better play and clamp action of steel bars like this, and can good completion prevent the function that reinforcing bar falls back.
As preferably, one support arm and support post in the described a pair of charging roller are hinged, also are provided with a rocking arm on this support arm, also are provided with an adjustment screw on the said support post, and the front end of said adjustment screw can offset with rocking arm.Design can be unclamped an one-way wheel when needs are taken out reinforcing bar like this, and can better fix two one-way wheels, lets them better clamp reinforcing bar, prevents that reinforcing bar from falling back.
As preferably, said adjustment screw rear end also is provided with a handwheel of the confession holding.Be convenient for people to like this go to regulate adjustment screw with hand.
As preferably, also be provided with elastomer between the front end of described adjustment screw and the rocking arm.Design can slow down because often collision and the adjustment screw front end that causes and the wearing and tearing of rocking arm like this, prolongs their service life.
Description of drawings
Accompanying drawing is the structural representation that prevents the reinforcing bar backward gear that the utility model is used for the steel bar girder make-up machine.
As shown in the figure: 1, a pair of charging roller; 2, reinforcing bar; 3, support post; 4, support arm; 5, rocking arm; 6, adjustment screw; 7, handwheel; 8, elastomer.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing, but the utility model is not limited only to the following specific embodiment:
As shown in the figure, a kind of be used for the steel bar girder make-up machine prevent the reinforcing bar backward gear, it comprises a pair of charging roller 1 that is installed on the steel bar girder make-up machine charging aperture, said charging roller adopt make reinforcing bar 2 can only from after the one-way wheel that moves forward.
Described being installed in is meant on the steel bar girder make-up machine charging aperture that it also comprises a support post 3, and described a pair of charging roller 1 is installed on the support post 3 through support arm 4.
One support arm 4 in the described a pair of charging roller 1 is articulated and connected with support post 3, also is provided with a Rocker arm 5 on this support arm 4, also is provided with an adjustment screw 6 on the said support post 3, and the front end of said adjustment screw 6 can offset with Rocker arm 5.
Said adjustment screw 6 rear ends also are provided with a handwheel of the confession holding 7, and it is comfortable and convenient that handwheel 7 is mainly regulated adjustment screw for hot topic exactly.
Also be provided with elastomer 8 between the front end of described adjustment screw 6 and the Rocker arm 5, said elastomer 8 can be that spring also can be a rubber.
The said operation principle that prevents the reinforcing bar backward gear that is used for the steel bar girder make-up machine is: at first let reinforcing bar 2 get between two charging rollers 1 through the hole on the support post 3; Rotate handwheel 7 then; Adjustment screw 6 is moved forward withstand Rocker arm 5; Rocker arm 5 drives support arm 4 then, and then drives one of them charging roller and press downwards, pushes down reinforcing bar 2 with another one charging roller; Because this a pair of feed roller wheel adopts is one-way wheel, reinforcing bar 2 can not move to move forward only backward so again.When reinforcing bar 2 is drawn forward; Two one-way wheels are rotary, promptly are in top charging roller and rotate counterclockwise, and are in following charging roller and clockwise rotate; Reinforcing bar 2 can normally move forward like this; When reinforcing bar 2 was pulled rearward, two charging rollers can not rotate, and so just blocked reinforcing bar 2 and did not allow it to move backward.And one-way wheel is that prior art has, so can directly use.
