Description
Technical field
The present invention relates to welding procedure field, be specially a kind of welding welding tractor continuously.
Background technology
In welding field especially continuous welding process, generally require to use and be attached with the welding tractor butt welded seam of welding gun and persistently weld.Shape residing for the weld seam of workpiece is different, welding tractor face upward before may experiencing horizontal path section, inclination angle in running upward trend line segment or inclination angle layback downhill path line segment.In each route segment, welding tractor all can carry out the direct of travel moved forward and backward.
But, due to the existence of these gradients, the control of the speed of service of welding tractor may be interfered.And, when the gradient is bigger, welding tractor is lost to be likely to result in due to the accident of power and is slipped the generation of the accidents such as car.And when the gradient is less, owing to the acceleration of gravity impact is likely to interfere gait of march.And the varying in size of the gradient, it affects difference.
Summary of the invention
It is an object of the invention to provide a kind of welding welding tractor continuously, it can overcome defect of the prior art.
nullAccording to the present invention，A kind of welding welding tractor continuously，Including for carrying the vehicle frame of welding gun and being installed with front-wheel the front axle being rotatably connected with described vehicle frame and be installed with trailing wheel the hind axle being rotatably connected with described vehicle frame，Described front axle is provided with usable rotational direction contrary front axle the first unilateral bearing and front axle the second unilateral bearing the most separatedly，Described hind axle is provided with usable rotational direction contrary rear axle the first unilateral bearing and rear axle the second unilateral bearing the most separatedly，It is additionally provided with front driving wheel on described front axle，Described front driving wheel is connected with by motor-driven drivewheel power by driving front band，It is additionally provided with rear drive sprocket on described hind axle，Described rear drive sprocket is also connected with by motor-driven drivewheel power by rear transmission band，Described motor is fixing with described vehicle frame to be connected，It is provided with electronic-controlled installation on the shell of described motor to electrically connect with described motor，Described electronic-controlled installation is in order to control the rotating speed of described motor，Such that it is able to control described front-wheel and the movement velocity of described trailing wheel as required，It is provided with damping cushion between described motor and described vehicle frame，Described damping cushion increases, in order to reduce described motor operationally produced shaking force, the stability that described motor runs，Guarantee that described vehicle frame will not produce rock because of the shaking force of described motor，The bottom of described vehicle frame is further fixedly arranged on and is perpendicular to the axial direction of described front axle and hind axle and the first track strip of longitudinal extension and the second track strip，Double wheel axle one-way brake slide block it is supported with slidably on described first track strip and the second track strip，The main part of described double wheel axle one-way brake slide block and extends longitudinally across described front axle and hind axle between axle the first unilateral bearing and rear axle the second unilateral bearing between described front axle the first unilateral bearing and front axle the second unilateral bearing in the rear，And be provided perpendicular at described front axle the first unilateral bearing anterior position longitudinal direction extend and bottom overcome in the front track of the first track strip the first track strip in front compression spring set towards described front axle the first unilateral bearing slidably front axle the first unilateral bearing braking protrude，At front axle the second unilateral bearing rear position, it is provided perpendicular to longitudinal direction extension and bottom overcomes the second track strip to protrude towards the braking of described front axle the second unilateral bearing slidably front axle the second unilateral bearing in front compression spring set in the front track of the second track strip，And at rear axle the first unilateral bearing anterior position, it is provided perpendicular to longitudinal direction extension and bottom overcomes the first track strip to protrude towards the braking of described rear axle the first unilateral bearing slidably rear axle the first unilateral bearing in rear compression spring set in the rear track of the first track strip，At the rear position of rear axle the second unilateral bearing, it is provided perpendicular to longitudinal direction extension and bottom overcomes the second track strip to protrude towards the braking of described rear axle the second unilateral bearing slidably rear axle the second unilateral bearing in rear compression spring set in the rear track of the second track strip，Thus，When the slope angle of the route advanced when workpiece is welded by described welding tractor makes described double wheel axle one-way brake slide block entirety slide backward，Described front axle the first unilateral bearing and rear axle the first unilateral bearing are protruded by the braking of described front axle the first unilateral bearing respectively and rear axle the first unilateral bearing brakes the conjugation protruded，So that described welding tractor in the direction of motion downward along slope angle by braking action，Braking action is not being had in the slope angle direction of motion upwards；When the slope angle of the route advanced when workpiece is welded by described welding tractor makes described double wheel axle one-way brake slide block entirety forward slip, described front axle the second unilateral bearing and rear axle the second unilateral bearing are protruded by the braking of described front axle the second unilateral bearing respectively and rear axle the second unilateral bearing brakes the conjugation protruded, so that described welding tractor in the direction of motion downward along slope angle by braking action, in the slope angle direction of motion upwards, there is no braking action；When the slope angle of the route advanced when stating welding tractor and welding workpiece is zero, described first track strip at front compression spring set, the second track strip at front compression spring set, the first track strip at rear compression spring set and the second track strip under the effect of rear compression spring set, described front axle the first unilateral bearing, front axle the second unilateral bearing, rear axle the first unilateral bearing and rear axle the second unilateral bearing do not engage with described double wheel axle one-way brake slide block and produce braking action.
Pass through such scheme, due to the brake silpper that is affected by gravity can under the effect of different slopes directions and different inclined degrees servo-actuated real estate lively state braking effect, and matched with brake silpper by unilateral bearing, can be freely-movable on the direction in opposite direction with braking motion, thus decrease the driving force loss of main driving direction, and do not interfere with the dynamic Control of this main driving direction.In particular, the loaded effect of increasing will not be produced for the driving force during going up a slope.And in approximate range in the horizontal direction, as long as less than certain angle of inclination, due to the existence of groups of springs, each braking position is all without the unilateral bearing on antero posterior axis produces braking action, thus run the motion of its fore-and-aft direction.Whole plant running is reliable, stabilized structure, it is possible to solve defect of the prior art very well.
