The structure of above-mentioned haulage gear comprises: two traction wheels and be positioned at two contact rollers that can move up and down above the traction wheel; Described two traction wheels comprise initiative traction wheel and driven traction wheel, and wherein initiative traction wheel is fixed on driving shaft one end, and drive sprocket also is housed on driving shaft, and the other end of driving shaft connects the driving mechanism that drives the driving shaft rotation.Described driven traction wheel is fixed on driven shaft one end, and driven sprocket also is housed on driven shaft; Chain connects drive sprocket and driven sprocket.When the rotation of drive mechanism driving shaft, then drive sprocket and initiative traction wheel rotate thereupon, rotate by chain drive driven sprocket and driven traction wheel thereupon.Contact roller above being positioned at traction wheel moves down, and when reinforcing bar being pressed on the traction wheel of rotation, traction wheel drives the reinforcing bar reach under the effect of frictional force, realizes the traction reinforcing bar.The initiative traction wheel of prior art is identical with driven traction wheel external diameter; The external diameter of contact roller is also identical.
When the automatic hoop bender of prior art often bar bending occurs, directly cause the reinforcing bar that is arranged in haulage gear also to occur reversing thereupon, the drawing-in motion of reinforcing bar is obstructed, also the finished product initiating terminal of the crooked back of influence reinforcing bar and clearing end can not be in the desired location closures simultaneously, and particularly when the sectional dimension of processed finished product stirrup greatly the time, the reinforcing steel bar twisting phenomenon is even more serious, cause deterioration in quality, waste of manpower, material resources are incured loss through delay the duration, directly influence construction speed.
For overcoming the defective of prior art reinforcing steel bar twisting, the someone proposes to be provided with the preventing reinforcing steel bar twisting device between two traction wheels, and this preventing reinforcing steel bar twisting device comprises: the anti-wheel of turning round; The anti-back shaft of turning round wheel is housed, and described back shaft is installed in the sliding sleeve, in the slotted hole of the upper case that is arranged on automatic hoop bender that this sliding sleeve moves up and down; Top at sliding sleeve is provided with screwdown gear; Bottom at sliding sleeve is provided with resetting means.Though above-mentioned preventing reinforcing steel bar twisting device plays the effect that prevents reinforcing steel bar twisting, also has complex structure, manufacturing cost height, the defective that maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of reinforcing bar in BENDING PROCESS, can prevent reinforcing steel bar twisting, and is simple in structure, low cost of manufacture, the haulage gear with preventing reinforcing steel bar twisting easy to maintenance.
The technical scheme that solves the problems of the technologies described above is: a kind of haulage gear with preventing reinforcing steel bar twisting, described haulage gear with preventing reinforcing steel bar twisting is arranged on the frame, its structure comprises: initiative traction wheel, driven traction wheel, be positioned at initiative traction wheel and active contact roller above the driven traction wheel and driven contact roller, the external diameter of described initiative traction wheel and the external diameter of driven traction wheel do not wait.
The beneficial effects of the utility model are: the utility model is a kind of to the improvement on the prior art reinforcing bar process equipment haulage gear, particularly to the improvement of the haulage gear on automatic hoop bender or the straightener.The utility model is not increase any device between two traction wheels, and the external diameter that only changes traction wheel just can effectively prevent reinforcing steel bar twisting.The utility model cooperates the contact roller that is complementary that reinforcing bar is pulled under heeling condition by the variation of two traction wheel external diameters, can prevent effectively that the reinforcing steel bar twisting of sweep from having influence on the reinforcing steel bar twisting of traction element.The utility model prevents that in practice reversing of reinforcing bar from playing positive effect, has simple in structurely, omits prior art and sets up the preventing reinforcing steel bar twisting device, and the manufacturing cost of equipment reduces by 15%, has advantages such as easy to maintenance.
