The structure of above-mentioned prior art 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 is fixed with the belt wheel that is connected with motor.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 motor rotates, drive belt wheel and driving shaft rotation by conveyer belt, 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 depressing under the drive mechanism, 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.
There is following defective in above-mentioned haulage gear of the prior art: the traction wheel external diameter both sides of the edge that contact with reinforcing bar in the haulage gear do not have and block, be that traction wheel is flat wheel, in distraction procedure, trailed reinforcing bar is not owing to there is restraint device, traction wheel is left in skew easily, causes the traction of reinforcing bar to be obstructed, and influences the hoop bender operate as normal, make percent defective rise waste of manpower, material resources.
For overcoming the defective of above-mentioned reinforcing bar skew, be provided with conduit at reinforcing bar through two traction wheels front and back, retrain reinforcing bar by conduit, because conduit is fixed, reinforcing bar is sent in the process and conduit generation sliding friction in traction during the traction reinforcing bar, cause and scratch reinforcing bar, conduit rapid wear, increase adverse consequences such as tractive resistance, the quality of the machine that makes descends.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of both sides at the traction wheel external diameter to be provided with the projection that is higher than external diameter, prevents that the steel-bar automatic hoop bender of reinforcing bar skew in distraction procedure from preventing the haulage gear that reinforcing bar is offset.
The technical scheme that solves the problems of the technologies described above is: a kind of steel-bar automatic hoop bender prevents the haulage gear of reinforcing bar skew, described steel-bar automatic hoop bender prevents that the haulage gear of reinforcing bar skew from comprising: the driving mechanism that traction wheel, contact roller, driving traction wheel rotate, drive the driving mechanism of depressing that contact roller moves, be provided with the projection that is higher than external diameter in the both sides of described traction wheel external diameter.
The beneficial effects of the utility model are: the utility model is a kind of technological improvement to prior art hoop bender haulage gear, be provided with the projection that is higher than external diameter in the both sides of described traction wheel external diameter, this projection forms the slot type structure on the traction wheel external diameter, can effectively prevent reinforcing bar skew under the state of reinforcing bar compressing.The utility model is simple in structure, avoids the defective of prior art scuffing reinforcing bar, and is littler than the tractive resistance of utilizing conduit constraint reinforcing bar in the prior art.
