[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing cart.

[0002]

2. Description of the Related Art Conventionally, when fillet welding, butt welding, or the like is performed on a welding portion set along a longitudinal direction of a member, a welding cart as a processing cart is disposed on a horizontal plate. The welding trolley runs along the vertical plate. FIG. 2 is a perspective view of a conventional welding cart.

In the drawing, reference numeral 10 denotes a welding cart, on which a welding torch 32 is provided. The welding cart 10 has a motor 17, and is driven in the direction of arrow A by driving the motor 17 to rotate the drive wheels 21. Then, the wire 32a is supplied to the welding torch 32 via the welding torch cable 32b as the welding cart 10 travels.

When the welding cart 10 is moved along a vertical plate (not shown), if the welding cart 10 moves away from the vertical plate, the tip of the welding torch 32 cannot be accurately directed to the welding position. As a result, the arc generated by the welding torch 32 cannot be accurately directed to the welding location, so that the strength of the welded joint decreases or welding cannot be performed.

Therefore, the bogie main body 11 of the welding bogie 10 is provided.
A pair of arms 23a and 23b are protruded toward the vertical plate material on one side, and rollers 24a and 24b that follow (arrange) rollers 24a and 24b are rotatably supported at the tips of the arms 23a and 23b, respectively. And, of the arms 23a and 23b, the front arm 23 in the traveling direction of the welding bogie 10 is used.
The projecting amount of a is slightly smaller than the projecting amount of the rear arm 23b.

[0006] In this case, the welding carriage 10 is not parallel to the vertical plate, and is caused to run slightly toward the vertical plate. Therefore, during the traveling of the welding carriage 10, the copying rollers 24a and 24b are vertically moved. It is always pressed against the plate. At this time, the copying rollers 24a and 24b move on the vertical plate while rotating. In this way, welding line copying can be performed automatically.

[0007] A mounting condition adjusting device 159 is provided in order to accurately point the tip of the welding torch 32 toward a welding position. The welding torch 32 is mounted by tightening a torch clamp (torch holder) 31. 159. The mounting state adjusting device 159
Is a front-rear direction adjusting device 128 for moving the tip of the welding torch 32 back and forth (left and right with respect to the traveling direction of the welding bogie 10), and a vertical position for moving the tip of the welding torch 32 up and down. It comprises an adjusting device 129 and an angle adjusting bracket 30 for changing the inclination of the welding torch 32.

The front-rear position adjusting device 128 includes a knob 128a and a moving block 128b, and a trapezoidal screw (not shown) rotated by the knob 128a is provided in the moving block 128b.
Racks (not shown) are formed on the surface of a in correspondence with the trapezoidal screws. Therefore, the knob 128
By rotating a, the moving block 128 is rotated.
b can be moved in the direction of arrow C (left and right with respect to the traveling direction of the welding cart 10).

The vertical position adjusting device 129
Is a knob 129a, a moving block 129b, and a fixed block 129c fixed to the moving block 128b.
The knob 1 is provided in the moving block 129b.
The trapezoidal screw (not shown) rotated by 29a
Racks (not shown) are formed on the surface of the fixing block 129c so as to correspond to the trapezoidal screws. Therefore, by rotating the knob 129a,
The moving block 129b can be moved in the direction of arrow D (vertical direction).

Further, the angle adjusting bracket 30 is
A rectangle arranged in parallel with the moving block 129b
Adjusting plate 30a, and screws 30 for fixing the adjusting plate 30a to the moving block 129b at four corners of the adjusting plate 30a
b, an adjusting screw (not shown) provided on a side surface of the moving block 129b, and a fan-shaped plate (not shown). Therefore, the inclination of the welding torch 32 can be changed by rotating the adjusting screws and moving the fan-shaped plate.

[0011]

However, in the conventional welding bogie described above, in order to accurately point the tip of the welding torch 32 to the welding position, the front-rear position adjusting device 12 is required.
8. The vertical position adjusting device 129 and the angle adjusting bracket 30 are required, which not only complicates the structure but also increases the cost.

In addition, in order to accurately point the tip of the welding torch 32 to the welding position, it is necessary to operate three positions of the knobs 128a and 129a and the adjusting screw, which is troublesome. In addition, since vibration generated during the traveling of the welding trolley 10 is transmitted to the welding torch 32 via the mounting condition adjusting device 159, the tightening of the torch clamp 31 is easy to be loosened, and the tip of the welding torch 32 can be accurately welded Can no longer be turned on.

[0013] The present invention solves the problems of the above-described conventional processing trolley, can simplify the structure, can reduce the cost, and can easily and accurately set the tip of the welding torch. An object of the present invention is to provide a processing cart that can be directed to a welding location.

[0014]

In order to achieve the object, in a processing cart according to the present invention, a cart main body, wheels mounted on the cart main body and supporting the cart main body, driving means for rotating the wheels, and the cart are provided.

In another working cart of the present invention, a third plate extending downward from the second plate is further provided, and the working means is attached to a lower end of the third plate.

[0017]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a rear view of a welding bogie according to an embodiment of the present invention, FIG. 3 is a perspective bottom view of the welding bogie according to the embodiment of the present invention, and FIG. 4 is a plan view of a mounting state adjusting device according to the embodiment of the present invention. FIG. 5 is a side view of the mounting state adjusting device according to the embodiment of the present invention.

In the drawing, reference numeral 10 denotes a horizontal plate 81 at the time of welding.
Welding trolley as a processing trolley that can be run on
Is a bogie main body placed on the horizontal plate 81 by wheels 21a to 21d, and the bogie main body 11 is made of an aluminum case, and has a top wall 11a, a front wall 1
1b, a rear wall 11c, a right wall 11d disposed on the right side in the traveling direction, and a left wall 11e disposed on the left side in the traveling direction. The front wall 11b, the rear wall 11c, the right wall 11d, and the left wall 11 are located below the top wall 11a.
e, the right driving wheel storage chamber 52 is formed by the front wall 11b, the rear wall 11c, and the left wall 1 by the right wall 11d.
The left driving wheel storage chamber 53 is formed by 1e.

A permanent magnet 12 is provided in the magnet accommodating chamber 51. The permanent magnet 12 is swingably supported by brackets 16a and 16b hanging from the back surface of the top wall 11a. , A retracted position indicated by a solid line and an operating position indicated by a broken line in FIG. Therefore, the permanent magnet 1
A rotating shaft 13a is formed to protrude from an end of the second shaft 2a.
The rotating shaft 13a extends forward through the bracket 16a and the front wall 11b, and is fixed to the lever 14 outside the magnet housing chamber 51.
And extends rearward.

In order to prevent the permanent magnet 12 from falling further toward the right wall 11d than the retracted position, for example, the right wall 1
A first stopper (not shown) is attached to 1d. Further, when the permanent magnet 12 is further moved from the operating position to the horizontal plate 81.
A second stopper 55 is attached to the left wall 11e in the horizontal direction so as not to tilt to the side. A coil spring 15 is disposed between the permanent magnet 12 around the rotation shaft 13a and the bracket 16b, and the coil spring 15 urges the permanent magnet 12 toward the retracted position.

Therefore, when the lever 14 is rotated by a predetermined angle in the direction of arrow B to incline the permanent magnet 12 by the same angle, the permanent magnet 12 is caused by its own attractive force generated between itself and the horizontal plate 81. , Against the urging force of the coil spring 15,
Stop at 5 to take the operating position. During this time, since the lever 14 is rotated following the permanent magnet 12, a force for operating the lever 14 is unnecessary.

As described above, first, the lever 14 is applied with a small force.
By simply turning the armature by a predetermined angle, the permanent magnet 12 can be placed at the operating position, so that the operability of the welding cart 10 can be improved. On the other hand, when the welding cart 10 is not placed on the horizontal plate 81, the permanent magnet 12 does not generate an attractive force with the horizontal plate 81.
Even if the permanent magnet 12 is placed in the operating position by rotating the 4 by 90 °, unless the force for operating the lever 14 is given,
The permanent magnet 12 rises at a stretch due to the urging force of the coil spring 15 and assumes a retracted position. During this time, since the lever 14 is rotated following the permanent magnet 12,
No force is required to operate the lever 14.

Further, at the rear end of the bogie main body 11, a speed reducer 57 is disposed on the top wall 11a, and a motor 17 as driving means is disposed on the speed reducer 57.
Is reduced by the speed reducer 57, and the output shaft 57 of the speed reducer 57 is reduced.
output to a. A drive sprocket 18a is fixed to the output shaft 57a.
A chain (not shown) is provided between the motor and a driven sprocket (not shown) fixed to the rear wheel drive shaft 19a.
Therefore, the rotation output to the output shaft 57a can be transmitted to the rear wheel drive shaft 19a via the drive sprocket 18a, the chain, and the driven sprocket.

The rear wheel drive shaft 19a is rotatably supported by the bogie main body 11 at a rear end of the bogie main body 11 via a bearing (not shown). The right end (the left end in FIG. 3) of the rear wheel drive shaft 19a is
It extends through the right wall 11d and is fixed to the right rear wheel 21a outside the magnet housing chamber 51. The left end (the right end in FIG. 3) of the rear wheel drive shaft 19a is a left wall 11e.
And is fixed to the left rear wheel 21b outside the magnet housing chamber 51.

The welding trolley 10 is driven by a four-wheel drive system, and transmits the rotation transmitted to the rear wheel drive shaft 19a to the right front wheel 21c and the left front wheel 21c.
d.
To this end, the front wheel drive shaft 19b is connected to the bogie main body 1 via a bearing (not shown) at the front end of the bogie main body 11.
1 is supported rotatably. The right end of the front wheel drive shaft 19b extends through the right wall 11d, and is fixed to the wheel 21c outside the magnet housing chamber 51. The left end of the front wheel drive shaft 19b extends through the left wall 11e and is fixed to the wheel 21d outside the magnet housing chamber 51.

A sprocket 22a is mounted on the rear wheel drive shaft 19a, and a sprocket 22b is mounted on the front wheel drive shaft 19b.
Are fixed, and a chain 24 is stretched between the sprockets 22a and 22b. In this manner, the rotation generated by driving the motor 17 is transmitted to each wheel 21 through the drive sprocket 18a, the chain, the driven sprocket, and the rear wheel drive shaft 19a in that order.
a, 21b, and further transmitted to the wheels 21c, 21d via the sprocket 22a, the chain 24, the sprocket 22b, and the front wheel drive shaft 19b in order, so that the welding cart 10 can travel. In this case, each of the wheels 21a
21d are drive wheels. It should be noted that the vehicle can be driven in a two-wheel drive system using only the wheels 21a and 21b or only the wheels 21c and 21d as drive wheels.

Each of the wheels 21a to 21d is formed of a rubber material or the like.
Not only can a sufficient frictional force be generated between the wheels 21a to 21d and the horizontal plate material 81,
Even if a foreign substance is sandwiched between 1d and the horizontal plate 81, the welding cart 10 can be run stably. in this case,
The distance between the permanent magnet 12 and the horizontal plate 81 is about 7 [m
m], the attraction force generated by the permanent magnet 12 is about 10 kg, and the weight of the welding carriage 10 is about 8 kg.
Therefore, approximately 18 kg of force can be applied between the wheels 21a to 21d and the horizontal plate 81.

A welding torch 32 as a processing means is provided at the center of the bogie main body 11 so that welding can be performed while the welding bogie 10 is running.
It is arranged with the side up and the left wall 11e side down. The welding torch 32 is fixed to the mounting condition adjusting device 59 by tightening the torch clamp 31,
The wire 32a is projected from the tip. Further, a welding torch cable (not shown) is connected to the welding torch 32, and the wire 32a is supplied from a supply device (not shown) via the welding torch cable.

The torch clamp 31 tightens the pipe portion 32c of the welding torch 32 at three points in the axial direction so that the pipe portion 32c is slightly curved. Therefore, even when an external force is applied to the welding torch 32 when the welding torch cable is towed, the welding torch 32 can be prevented from rotating with respect to the torch clamp 31.

The mounting condition adjusting device 59 is used to accurately direct the tip of the welding torch 32 to a welding location as a processing location, and to move the tip of the welding torch 32 back and forth (in the running direction of the welding cart 10). Front-rear position adjusting device 28 for moving the welding torch 32 to change the inclination of the welding torch 32 and moving the tip of the welding torch 32 up and down. 29.

The front-back direction position adjusting device 28 includes a knob 2
8a and a moving block 28b. In the moving block 28b, a trapezoidal screw 28c rotated by the knob 28a is provided on a bracket 82 fixed to the top wall 11a in correspondence with the trapezoidal screw 28c.
d are respectively formed. Therefore, the knob 28a
By rotating the moving block 28b, the moving block 28b can be moved in the direction of arrow C (in the left-right direction with respect to the traveling direction of the welding carriage 10).

The swing adjusting device 29 includes a first plate 29 fixed to the longitudinal position adjusting device 28.
a, a second plate 29c slidably disposed about the hinge 29b with respect to the first plate 29a and extending obliquely upward from the hinge 29b;
Opening angle adjustment for adjusting the opening angle between the first plate 29a and the second plate 29c, the third plate 29d being formed integrally with the second plate 29c and extending downward from the edge near the tip of the second plate 29c. There is provided a mechanism 29e and a spring 85 as urging means for urging the second plate 29c in a direction to increase the opening angle.

The opening angle adjusting mechanism 29e is fixed to the first plate 29a, rises upward, and extends through a hole 88 formed in the second plate 29c. On the upper surface of 29c, there is a knob 87 screwed with the bolt 86. At the lower end of the third plate 29d, the torch clamp 31 is swingably supported around a bolt 91, and the welding torch 32 is tightened by the torch clamp 31. As the opening angle changes, the second plate 29c moves in the vertical direction. At this time, the holes 88 are moved so that the movement of the second plate 29c is not interfered by the bolts 86.
Is made larger than the outer diameter of the bolt 86. Further, instead of the hole 88, a long groove, a notch or the like can be formed.

Therefore, when the knob 87 is rotated to increase the opening angle according to the urging force of the spring 85, the tip of the welding torch 32 is rotated clockwise in FIG. 1 around the hinge 29b. As a result, the inclination of the welding torch 32 can be reduced, and the tip of the welding torch 32 can be moved upward. On the other hand, when the knob 87 is rotated in the opposite direction to reduce the opening angle against the urging force of the spring 85, the tip of the welding torch 32 rotates counterclockwise in FIG. 1 around the hinge 29b. Be moved. Therefore, the inclination of the welding torch 32 can be increased, and the tip of the welding torch 32 can be moved downward. The first plate 29a and the second plate 29c
Spring receiving grooves 93 and 94 are formed on the opposing surfaces of the first plate 29a and the second plate 29c, respectively, so that the spring 85 does not come off from between the first and second plates 29a and 29c. In the present embodiment, the coil-type spring 8 is used.
Although 5 is used, a plate-shaped spring can also be used. Further, the spring 85 is connected to the first plate 29a.
And the second plate 29c, it is possible to arrange a coil-type spring on the hinge 29b.

As described above, in order to accurately point the tip of the welding torch 32 toward the welding position, the front-rear position adjusting device 28 is used.
And only the swing adjusting device 29 is required, so that the structure can be simplified, and
Cost can be reduced. Moreover, in order to accurately point the tip of the welding torch 32 to the welding position, the knob 28
The operation is easy because only the two points a and 87 need to be operated.

In this case, the welding torch 32 is connected to the hinge 29b.
When the tip of the welding torch 32 is vertically moved by changing the inclination of the welding torch 32 by the swing adjustment device 29, the tip of the welding torch 32 It is moved in the left-right direction in FIG. Accordingly, the adjustment amount of the front-rear direction position adjustment device 28, that is, the operation amount of the knob 28a can be reduced accordingly.

Further, even if the vibration generated during the traveling of the welding cart 10 is transmitted to the mounting condition adjusting device 59, the vibration is buffered by the spring 85, so that the torch clamp 31 is hardly loosened. Therefore, welding torch 32
Can be accurately directed to the welding point. Further, since the pipe portion 32c can be maintained in a slightly curved state, even if an external force is applied to the welding torch 32 when the welding torch cable is pulled, the welding torch 3 is not used.
2 can be sufficiently prevented from rotating with respect to the torch clamp 31.

The hinge 29b is disposed on the rightmost side with respect to the traveling direction of the welding carriage 10 on the moving block 28b and at the highest part of the welding carriage 10, and the second plate 29c extends obliquely upward from the hinge 29b, the third plate 29d extends downward from an edge near the tip of the second plate 29c,
Since the torch clamp 31 is provided at the lower end of the second plate 29c, the distance between the hinge 29b and the torch clamp 31 can be increased.

Therefore, the welding torch 32
Of the welding torch 32 when the knob 87 is rotated can be prevented from greatly changing. Adjustment characteristics can be improved. A control box (not shown) is fixed on the top wall 11a, and various knobs and the like are disposed on the control box. By operating the knobs and the like, the welding cart 10 is switched between running and stopping. , The running speed can be changed, and the start and end of welding can be switched.

When the welding carriage 10 having the above configuration is moved along a vertical plate (not shown) and is welded by the welding torch 32, the metal (not shown) melted with the welding may be scattered. Then, when the scattered metal solidifies and enters the left driving wheel accommodating chamber 53, and is caught between the wheels 21a to 21d and the horizontal plate 81,
The welding bogie 10 spins and cannot perform welding line copying, and cannot perform welding.

Therefore, a skirt 72 is provided outside the left driving wheel storage chamber 53, and the skirt 72 covers the left driving wheel storage chamber 53. Since the skirt 72 is attached to the bogie main body 11 so as to be able to move up and down, the lower end can always be slid on the horizontal plate 81 while the welding bogie 10 is running. Also,
When the bogie main body 11 reaches the welding end point, a front wall 11b is provided so that the bogie main body 11 can be stopped.
, A stop switch 75 is provided. The stop switch 75 has a pressing portion 75a which is constantly urged forward by a spring or the like (not shown). On the other hand, at the welding end point, a stopper (not shown) is provided in advance at a position corresponding to the pressing portion 75a.

Therefore, when the bogie main body 11 reaches the welding end point, the pressing portion 75a is pressed by the stopper against the urging force of the spring and retreats, and the stop switch 75 is operated. As a result, the motor 17 is stopped, and the welding cart 10 is stopped. In addition, a handle (not shown) is formed by standing up from the rear wall 11c of the bogie main body 11, and the handle functions as a handle for carrying the welding bogie 10 after welding is completed, and places the permanent magnet 12 at the retracted position. With the function of a lever.

That is, when the welding is completed and the operator inclines the handle by, for example, about 5 °, the welding cart 10 is centered on the rightmost and lowermost point of the wheels 21a and 21c. The permanent magnet 12 which is tilted in the same direction and is in the operating position is also tilted in the same direction,
2 and the horizontal plate member 81 become non-parallel. As a result, the attractive force generated between the permanent magnet 12 and the horizontal plate 81 is reduced, so that the permanent magnet 12
And get up at once and take the evacuation position. During this time, since the lever 14 is rotated following the permanent magnet 12, a force for operating the lever 14 is unnecessary. The permanent magnet 12 can be rotated by operating the lever 14 without tilting the handle.

By the way, when the welding bogie 10 having the above configuration is run along a vertical plate, if the welding bogie 10 is separated from the vertical plate, the tip of the welding torch 32 cannot be accurately directed to a welding position. In addition, the strength of the welded joint is reduced, or welding cannot be performed.
Therefore, a pair of arms 23 is provided on the left side of the carriage body 12.
a, 23b are projected toward the vertical plate member, and the copying rollers 24a, 24a,
4b is rotatably supported. In addition, each of the arms 23
a and 23b are respectively connected to the front wall 11b by bolts 62.
And the rear wall 11c so that the position of each arm 23a, 23b in the horizontal direction with respect to the bogie main body 11 can be adjusted. Reference numeral 61 denotes a groove formed in each of the arms 23a and 23b, and the bolt 62 moves in the groove 61 as the position of each of the arms 23a and 23b is adjusted.

Therefore, each of the arms 23a, 23b
Of these, if the amount of protrusion of the front arm 23a in the traveling direction of the welding trolley 10 is slightly smaller than the amount of protrusion of the rear arm 23b, the welding trolley 10 does not become parallel to the vertical plate material, Since the vehicle is made to travel toward the vertical plate, the copying rollers 24a and 24b are pressed against the vertical plate via the arms 23a and 23b, respectively.

In this manner, welding line copying can be performed automatically. At this time, the copying roller 24
a and 24b move on the vertical plate while rotating. In this embodiment, the welding trolley 10 is used as the processing trolley, and the welding torch 32 is mounted on the welding trolley 10 to perform welding. However, the gas cutting trolley is used as the processing trolley, and the gas cutting trolley is used. A gas cutting torch can be mounted on the cutting cart to perform gas cutting.

The present invention is not limited to the above embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention.

[0048]

As described above in detail, according to the present invention, in a processing cart, a cart main body, wheels mounted on the cart main body, supporting the cart main body, and driving means for rotating the wheels. And processing means that is swingably attached to the bogie main body by an attachment state adjusting device.

The mounting condition adjusting device is disposed on the first plate and the first plate so as to be swingable about a hinge, and the second plate extends obliquely upward from the hinge.
A plate, an opening angle adjusting mechanism for adjusting an opening angle between the first plate and the second plate, and an urging means for urging the second plate in a direction to increase the opening angle.

In this case, the processing cart can be run by driving the driving means and rotating the wheels. And since the said mounting state adjustment apparatus only has a 1st plate, a 2nd plate, an opening angle adjustment mechanism, and a biasing means, the structure for correctly directing the front-end | tip of a processing means to a processing location is simplified. Not only can reduce the cost of the processing cart. Moreover, in order to accurately point the tip of the processing means to the processing location,
The operation is easy because only the opening angle adjustment mechanism needs to be operated.

Further, even if the vibration generated during the traveling of the processing cart is transmitted to the mounting condition adjusting device, the vibration is buffered by the urging means, so that the tightening for fixing the processing means is not easily loosened. Therefore, the tip of the processing means can be accurately directed to the processing location. In another processing cart of the present invention, a third plate extending downward from the second plate is further provided, and the processing means is attached to a lower end of the third plate.

In this case, the distance from the swing center to the tip of the machining means, that is, the swing radius can be increased, so that the inclination of the machining means when the opening angle adjusting mechanism is operated is largely changed. Can be prevented. Therefore, the adjustment characteristics of the mounting state adjusting device can be improved.
