な倣いが確保できるようにしている。この例ではすみ肉
溶接のもう一方の対象である下板は充分に広く、台車は
該下板を支障なく走行できることを前提としている。As a railless self-propelled bogie for horizontal fillet welding, one in which a pair of copying rollers abutting on a standing plate is attached to the front and rear of one side of the bogie is widely used. An example of this is an actual welding machine such as 53-12732 "Automatic Welding Machine", in which a pair of guide arms are attached to one side of a truck to abut the standing plate, and the front / rear wheels of the truck with respect to the traveling direction. Even if the standing plate is tilted and is cylindrical, a reliable copy can be secured. In this example, it is premised that the lower plate, which is the other target of fillet welding, is sufficiently wide so that the carriage can travel on the lower plate without any trouble.
他の例としては特公昭51−12014「角部溶接用走

であり、そこで台車の車輪には永久磁石を用いている。
また立板の高さ低いので、案内腕は縦板を越して裏面で
当接するようにしている。Another example is JP-B-51-12014 "Corner welding welding carriage". The traveling surface (lower plate) is wide, but it is a curved surface, and permanent magnets are used for the wheels of the truck.
Further, since the height of the standing plate is low, the guide arm is arranged to contact the back surface of the guiding plate over the vertical plate.

落ち、走行が不安定になる。In the case of a self-propelled welding machine that travels on the lower plate, it is difficult to use if the width of the lower plate is narrow and one of the left and right wheels of the bogie protrudes. Also, a lighter dolly is easier to handle, but it lacks running stability, and if the running surface is a curved surface such as a cylindrical surface, ordinary wheels may slip.In such a case, magnet wheels are effective. Is. However, in the magnet wheel, when foreign matter enters between the magnet wheel and the traveling surface (lower plate), the attraction force decreases, and the traveling becomes unstable.

動される。FIG. 1 is a plan view of a railless self-propelled carriage according to the present invention, and FIG. 2 is a side view of the same. A and B are members to be welded. As a specific example, A is a cylindrical body having a diameter of 880 mm and the like, B is a reinforcing ring that abuts on the inner surface thereof, and these abutting portions are welded by a welding torch 17 to a horizontal fillet. Weld. The thickness of the cylindrical body A is 14 to 16 mm, and the width of the reinforcing ring B is about 150 mm. This width is insufficient for running the welding carriage. Therefore, in the present invention, a method of sandwiching the reinforcing ring (lower plate) B from above and below is adopted. Reference numerals 2a to 2d are guide wheels for holding the lower plate B from the upper side, and 5 are drive wheels for holding the lower plate B from the lower side. These are attached to a truck frame 18, and a handle 16 is attached to the truck frame. Although the wheels 2a to 2d are driven wheels, the wheel 5 is a driving wheel and is driven by the traveling motor 4.

The trolley travels in the direction of arrow F. When the guide wheels 2c and 2d are tilted so as to move toward the standing plate A as shown in the drawing, the front guide arm (the arm to which 1a is attached) is the rear guide arm. If it is made shorter than the (arm to which 1b is attached), the dolly will move closer to the standing plate side as it travels, but it will be blocked by the copying rollers (copying wheels) 1a and 1b, and the dolly will end up along the standing plate. You will be able to drive. Wheel 2a that contacts the upper surface of the lower plate
.About.2d are at each corner of the rectangle, but the drive wheel 5 that contacts the lower surface of the lower plate is located at the center of the rectangle.

The lifting mechanism part of is shown. Reference numeral 9 is a slider for supporting the drive wheel 5, 8 is a guide rod thereof, 12 is a pin attached to the side surface of the slider 9, and 11 is a rotating shaft of a lever 10 attached to a carriage frame 18. The tip of lever 10 is 2
It is a crotch, and this portion engages with the pin 12. When the lever 10 is pushed down as shown by the dotted line in FIG. 4, the tip 2 crotch portion rises, which causes the slider 9 to rise and the drive wheel 5 to move.
To the lower plate B. When the drive wheel 5 is separated from the lower plate, the reverse operation is performed. Spring 6 is always slider 9
Since the lever 9 is pushed up, the slider 10 is retracted by the lever 10 against the spring pressing force, and the hook 13 holds the slider 9 in the retracted position.

解除を行なう。FIG. 7 is a perspective view showing the relationship between the hook 13 and the lever 10. The lever 10 is composed of two parts, a front end part 10a having two crotch parts and a rear end part 10b which is manually operated.
Is pivoted by a rotary shaft 11 and is orthogonal to the rotary shaft 1.
The front / rear end portions 10a / 10b are connected by 9. Therefore the rear end portion 10b can be rotated in four directions of the arrows F 1 to F 4,
Rotation in the directions of the arrows F 1 and F 2 causes the slider 9 to move forward and backward, and rotation in the directions of the arrows F 3 and F 4 causes the lever 13 to engage with and disengage from the hook 13.

い。The rear wheels 2c and 2d are mounted so as to be inclined, which is shown in detail in FIG. Upright plate A contact at the point where the copying roller 1b contacts the rear portion P, the wheels 2c, if the center line l 1, l 2 of the 2d of the rotating shaft to a tangent P and the angle and theta 1, the angle theta 1 is 90 Keep it below ゜. In this way, the rear part of the truck tries to approach the standing plate A as the truck advances in the direction of arrow F, and the copying roller 1b does not separate from the standing plate A.

長さの下がなくても倣い走行することができる。The standing plate A may be linear, but in this case as well, θ may be smaller than 90. FIG. 6 shows this case, where θ is represented by an angle θ 2 between the surface of the wheel and the standing plate A direction,
θ 2 is preferably 2 ° to 4 °. Rear wheel 2 in FIG.
In addition to c and 2d, the front wheels 2a and 2d are also inclined at the same angle, so that the front and rear parts of the carriage try to approach the standing plate A when traveling in the direction of the arrow, and the length of the pair of guide arms increases. It is possible to follow and travel without the bottom.
リミットスイッチ3は障害物に当ることにより作動する
が、この障害物は溶接対象に存在すればそれを利用し、
なければ溶接停止すべき位置に設置する。The limit switch 3 operates by hitting an obstacle. If this obstacle is present on the welding target, it is used,
If not, install it at the position where welding should stop.

る。This welding trolley has upper wheels 2a to 2d and lower wheels 5a.
Since the vehicle travels with the lower plate sandwiched between them, it is not possible to secure a sufficient traveling path due to the narrow width of the lower plate. Therefore, it is possible to perform stable traveling even when the left and right wheels of the bogie cannot be sufficiently spaced. In addition, since it is a method of sandwiching, sufficient pressure can be obtained between the wheels and the lower plate even if the trolley is lightweight and the permanent magnet wheels are not used, and reliable traveling without slips or the like is possible. Moreover, since the trolley is light in weight, it is easy to operate.

Can maintain a stable posture without tilting from the horizontal state. The wheels may be made of metal or may be fitted with rubber tires. The wheels can be moved forward / backward, and the distance between the left and right wheels may be changed according to the width of the ground.
