ある。A problem with this type of permanent magnet moving type traveling carriage is that a large force is required to carry the carriage attached to the floor steel plate by the magnetic force of the permanent magnets, and the labor burden on the operator is large. In a trolley having a magnet provided inside the main body, a relatively large space (air gap) is created between the attraction surface of the magnet and the work material forming the running surface of the trolley. Although the suction force can be increased and the traction force can be strengthened by arranging so as to be small, there is a limit in reducing the air gap due to dust such as spatter and slag on the work material. On the contrary, it is generally known that if the air gap is increased, the suction force is reduced and the traction force is reduced.Therefore, a means for reducing the air gap during welding and increasing it during transportation has been put into practical use. Both of the above prior arts are railless self-propelled welding traveling carriages having a characteristic structure in this respect.

The bolt 22 engaged in the upright state to the section is fixed,
The permanent magnet 4 is suspended and provided in the carriage body 1 by screwing the adjustment nut 26 and the bolt 22 rotatably attached to the upper surface of the carriage body 1. The height of the permanent magnet 4 can be adjusted by turning the adjusting nut 26. In order to prevent the permanent magnet 4 from rotating when the adjusting nut 26 is rotated, The side surface of 4 is brought into contact with the inner wall surface of the trolley body 1, or a pin 27 protruding from the permanent magnet 4 is inserted into a hole 28 provided in the trolley body 1 as shown in FIG. Taken to prevent rotation.

This is shown in FIG.

状態が図7(B)に示される。On the other hand, the structure and operation state of the main part in the practical example of the latter prior art is shown in FIGS. 7 (A) and 7 (B).
In this example, the permanent magnet 4 is basically attached to the carriage body 1 by the four-bar linkage 30 so as to be vertically movable. The permanent magnet 4 arranged inside the carriage body 1 is rotatably engaged with one end of the two connecting bars 33A and 33B by a pair of hinges 32.
Further, the other ends of the two connecting bars 33A and 33B are rotatably engaged with a bracket fixed to the carriage main body 1 by a pair of hinges 31. Further, a handle 7 is fixed to a rotation center portion of one of the connecting bars 33A on the hinge 31 side, and the connecting bar 33A and the handle 7 are integrally rotatable around the hinge 31. That is, the permanent magnet 4 can be moved up and down by turning the handle 7, and the permanent magnet 4 is lifted down and brought into contact with the bottom plate 15 to maximize the attraction force as shown in FIG. 7 (A). FIG. 7B shows a state in which the handle 7 is turned in the opposite direction to lift up the permanent magnet 4 and separate it from the bottom plate 15 to weaken the attraction force.

題点があった。In both of the prior arts shown in FIGS. 6 and 7, the bottom surface of the permanent magnet 4 is the traveling surface 2 in both cases.
Since it moves parallel to the bottom plate 15 parallel to 1, there is an advantage that efficient magnetic force adjustment can be performed, but on the other hand, when pulling up the permanent magnet 4 vertically upward to weaken the attraction force, Since a larger force than the sum of the total weight of the magnet 4 and the attraction force due to the magnetic force must be pulled in the direction opposite to the attraction force, a very large acting force is required, and as a result, the permanent magnet 4 is raised and lowered. In order to increase the size of the mechanism to operate and to operate with light force,
There is a problem that the booster mechanism is indispensable and the structure is complicated and expensive.

手段とから形成したことを特徴とする。The present invention has the following configuration to achieve the above object. That is, according to the present invention, a bogie main body including a pair of front wheels and rear wheels so as to be capable of self-propelling, a torch mounted on the bogie main body, and a profile attached to the main body of the bogie for copying a welding line. Means, a permanent magnet disposed inside the carriage main body at a distance from the traveling surface so as to be attracted to the travel surface, and a permanent magnet disposed opposite to the travel surface, and a magnet movable attached to the carriage main body for movably supporting the permanent magnet. A traveling carriage for railless self-propelled welding including a support mechanism, wherein the magnet movable support mechanism is a rotation support means for rotatably supporting one end of a permanent magnet around an axis parallel to a travel surface. It is characterized in that the other end of the permanent magnet facing the one end is formed of a moving support means for movably supporting in the vertical direction orthogonal to the traveling surface.

て軽くて済み、従って操作が容易かつ円滑になる。As described above, as a means for movably supporting the permanent magnet disposed inside the carriage main body, one end of the permanent magnet is fixed to rotate and the other end is supported so as to be movable up and down. Therefore, when separating the permanent magnet attracted to the bottom plate especially during transportation work, it can be easily separated from the bottom plate by giving a rotation moment to the center of gravity of the permanent magnet. Since the movement is performed by the rotary operation, the force required for the detaching operation is lighter than that of the conventional method of pulling up vertically, and therefore the operation is easy and smooth.

簡単なことと相俟って操作性がより向上する。With this configuration, the connecting plate member can smoothly absorb the difference in momentum and direction between the vertically movable moving handle and the other end of the vertically rotating permanent magnet. Therefore, the permanent magnet can be reliably moved by a simple operation of moving the moving handle up and down, and the operability is further improved in combination with the simple structure.

る利点がある。The bottom plate 15 of the trolley body 1 is fixedly provided at the lower part of the body so that it can face the running surface 21 in parallel at intervals of several cm.
At the position where they are brought into contact with each other and sucked (see FIG. 4), the air gap is reduced to exert the maximum suction force,
A large traction force can be exerted on the trolley body 1. On the other hand, at the position where the permanent magnet 4 is inclined at a predetermined angle with respect to the bottom plate 15 (see FIG. 5), the air gap is increased and a small attraction force is applied to the running surface 21 (material to be processed) of the running carriage. Can be easily separated from the surface). In this case, since the handle for the operator to grip during transportation and the handle for separating the permanent magnet 4 from the bottom plate 15 are shared by one moving handle 7, the structure is simple. Moreover, there is an advantage that the operation is simple.

る。The present invention has the structure as described above,
In this case, one end of the permanent magnet is fixed to rotate and the other end is supported so that it can move up and down. When separating, it is possible to easily separate it from the bottom plate by applying a rotation moment to the center of gravity of the permanent magnet, and in this case, the force required for the separation operation is necessary because the movement is performed by a boosting rotational operation. Is very light, easy to operate and smooth.
