Description
Technical field
The present invention relates to welding procedure field, specially a kind of welding tractor for contacting alarm.
Background technology
In welding field especially continuous welding process, generally require to use the welding tractor for being attached with welding gun to weld seam
Carry out continuing welding.Because the shape residing for the weld seam of workpiece is different, welding tractor may undergo in the process of running
The upward trend line segment faced upward before horizontal path section, inclination angle or the descending route segment of inclination angle layback.In each route segment, welding tractor
The direct of travel that can be all moved forward and backward.
But due to the presence of these gradients, the control of the speed of service of welding tractor may be interfered.And
And when the gradient is larger, welding tractor is likely to result in the generation of the accidents such as car slipping due to the unexpected forfeiture of power.And in the gradient
When smaller, because the acceleration that gravity influences be able to may also interfere to gait of march.And the gradient is of different sizes, it influences
It is different.
The content of the invention
It is an object of the invention to provide a kind of welding tractor for contacting alarm, and it can overcome of the prior art lack
Fall into.
According to the present invention, a kind of welding tractor for contacting alarm, including for the vehicle frame for carrying welding gun and fixed peace
The front axle that is rotatably connected equipped with front-wheel and with the vehicle frame and it is installed with trailing wheel and rotatable with the vehicle frame
The hind axle of connection, the front axle are separatedly provided with the opposite one-way shaft of front axle first of usable rotational direction in the axial direction
Hold and the opposite rear axle of usable rotational direction is separatedly installed in the axial direction with the unilateral bearing of front axle second, the hind axle
One unilateral bearing and the unilateral bearing of rear axle second, front driving wheel are additionally provided with the front axle, the front driving wheel passes through preceding

The bottom of vehicle frame is further fixedly arranged on the first rail of the axial direction perpendicular to the front axle and hind axle and Longitudinal extending
Road bar and the second track strip, double wheel axle one-way brake cunning is slideably supported with first track strip and the second track strip
Block, the main part of the double wheel axle one-way brake sliding block is between the unilateral bearing of front axle first and the unilateral bearing of front axle second
And the front axle and trailing wheel are extended longitudinally across between the unilateral bearing of axle first and the unilateral bearing of rear axle second in the rear
Axle, and it is provided perpendicular at the first unilateral bearing of front axle anterior position longitudinal direction extension and bottom is in the first rail
Overcome the first track strip slidable towards the unilateral bearing of front axle first in preceding compression spring set in the preceding track of road bar
The unilateral bearing of front axle first braking protrusion, at the second unilateral bearing of front axle rear position being provided perpendicular to longitudinal direction prolongs
Stretch and bottom overcomes the second track strip in preceding compression spring set in the preceding track of the second track strip and towards the front axle second
The slidable unilateral bearing of the front axle second braking protrusion of unilateral bearing, and set at rear axle the first unilateral bearing anterior position
Have be transversely to the machine direction direction extension and bottom the first track strip is overcome in the rear track of the first track strip in rear compression spring set
And towards the slidable unilateral bearing of the rear axle first braking protrusion of the unilateral bearing of rear axle first, in the unilateral bearing of rear axle second
Rear position at be provided perpendicular to longitudinal direction extension and bottom overcome the second track in the rear track of the second track strip
Bar protrudes in rear compression spring set towards the slidable unilateral bearing of rear axle second braking of the unilateral bearing of rear axle second, by
This, the slope angle for the route advanced when the welding tractor welds to workpiece make it that the double wheel axle one-way brake sliding block is whole
When body slides backward, the unilateral bearing of front axle first and rear axle first unilateral bearing is respectively by the one-way shaft of front axle first
Manufacture the conjugation of dynamic protrusion and the unilateral bearing of rear axle first braking protrusion so that the welding tractor along slope angle to
Under the direction of motion on by braking action, there is no braking action in the direction of motion upward along slope angle；When the welding is small
When the slope angle for the route advanced when car welds to workpiece causes the double wheel axle one-way brake sliding block entirety forward slip, institute
The unilateral bearing of front axle second and the unilateral bearing of rear axle second are stated respectively by the unilateral bearing of front axle second braking protrusion with after
The conjugation of the unilateral bearing of axle second braking protrusion, so that the welding tractor is in the direction of motion downward along slope angle
By braking action, there is no braking action in the direction of motion upward along slope angle；Workpiece is welded when stating welding tractor
When the slope angle of Shi Hangjin route is zero, in first track strip in preceding compression spring set, the second track strip in preceding compression bullet
Spring group, the first track strip in rear compression spring set and the second track strip in the presence of rear compression spring set, the front axle first
Unilateral bearing, the unilateral bearing of front axle second, the unilateral bearing of rear axle first and the unilateral bearing of rear axle second not with the double wheel axle
One-way brake sliding block engages and produces braking action, wherein, the unilateral bearing of front axle first braking protrusion is towards before described
On the end face of the unilateral bearing of axle first, the unilateral bearing of the rear axle first braking protrusion is towards the unilateral bearing of rear axle first
End face on, the unilateral bearing of the front axle second braking protrusion on the end face towards the unilateral bearing of front axle second and
The unilateral bearing of the rear axle second braking protrusion is provided with contact on the end face towards the unilateral bearing of rear axle second and passed
Sensor, the feeler electrically connect with the alarm being arranged on the vehicle frame, and the feeler is to work as
The unilateral bearing of front axle first and the unilateral bearing of rear axle first are stated respectively by the unilateral bearing of front axle first braking protrusion with after
The conjugation or the unilateral bearing of the front axle second and the unilateral bearing point of rear axle second of the unilateral bearing of axle first braking protrusion
Transmitted when not braked the conjugation of protrusion by the unilateral bearing of front axle second braking protrusion and the unilateral bearing of rear axle second
Signal controls the alarm to send the sound of alarm, and in above-mentioned conjugation state, the feeler is triggered.
By such scheme, because the brake silpper being affected by gravity can be in different slopes directions and difference
Inclined degree in the presence of and the servo-actuated lively state braking effect of real estate, and be engaged by unilateral bearing with brake silpper,
Can the free movement on the direction in opposite direction with braking motion, so as to reduce the driving force of main driving direction loss, and
And the dynamic Control of this main driving direction is not interfered with.In particular, increase will not be produced for the driving force during upward slope
The effect of load.And in approximate range in the horizontal direction, as long as being no more than certain angle of inclination, due to depositing for groups of springs
Each braking position produces braking action all without to the unilateral bearing on antero posterior axis, thus runs the fortune of its fore-and-aft direction
It is dynamic.Whole device is reliable, stabilized structure, the defects of can solving in the prior art very well.
