Abstract

PURPOSE:To utilize a ring for reinforcing as a traveling rail by providing a traveling mechanism having guide rollers to engage with a flange of shape steel and a driving roller to generate the travel driving force with the frictional force at the interval with the flange. CONSTITUTION:A holding roller 18 of a traveling device 4 is first opened fully and the automatic continuous welding machine 1 is fitted to the wind resistant ring 13 of H-shape steel fitted for reinforcing to a structure during assembling in a state with a welding head 2 upward. In this state, since the tilting moment in the arrow M direction acts according to the positional relation of the center of gravity of a machine body, the position thereof is maintained stably by the press-contact force of the respective guide rollers 14 and 15 with each surface of the front and rear of the flange 13a. The ring 13 for reinforcing provided for assembling steel plates temporarily at the time of building the structure can be utilized as the traveling rail of the automatic continuous welding machine 1. Accordingly, since it becomes unnecessary to set up a rail for exclusive use separately, it produces a great effect to be able to reduce the stages.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic continuous welding machine used for constructing a large structure such as a tank with a steel plate welded structure.

[0002]

2. Description of the Related Art Large structures, which are formed by welding and joining steel plates represented by tanks, silos, and chimneys, are usually constructed by using an automatic continuous welding machine. This automatic continuous welding machine is generally mounted on a trolley that travels by engaging a pinion gear provided on a wheel with a rack gear formed on a dedicated guide rail.

[0003]

In the case where the horizontal surface is to be welded downward, the rail can be easily extended along the welding line on the base material of the steel sheet. In this case, since sideways welding at a relatively high place is overwhelmingly common, it is not enough to simply place the rail, and its installation is very troublesome.

The present invention was devised in view of the disadvantages of the prior art as described above, and its main purpose is to provide a traveling mechanism improved so as not to trouble the installation of the rail. To provide an automatic continuous welding machine.

[0005]

According to the present invention, an object of the present invention is to provide an automatic continuous welding machine used when a large structure such as a tank is constructed with a welded structure of steel plates, and a flange of a shaped steel material. It is achieved by providing a traveling mechanism having a driving roller that generates a traveling driving force by a frictional force between the guide roller and the flange engaging with the driving roller.

[0006]

With this structure, I-shaped steel or H-shaped steel temporarily fixed to the base material for reinforcement during assembly can be used as the rail. Therefore, it is not necessary to install a rail exclusively for traveling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

1 and 2 show the whole of an automatic continuous welding machine provided with a traveling mechanism constructed according to the present invention. The automatic continuous welding machine 1 includes a welding head 2, a welding wire supply reel 3, a traveling device 4, and a control device 5 for controlling traveling and welding. As a whole, the frame of the traveling device 4 is provided. 6 is integrally assembled.

The welding head 2 includes a welding torch 7, a wire straightening device 8, and a wire feeding device 9 for sequentially drawing the welding wire from the welding wire supply reel 3 and continuously feeding it to the welding torch 7. The position and angle of the welding torch 7 with respect to the base material 12 can be appropriately adjusted by the universal clamp mechanism 10 and the slide mechanism 11 using screws.

The traveling device 4 includes a guide roller 14 that comes into contact with the rear surface of the flange 13a of the wind resistant ring 13 made of I-shaped steel or H-shaped steel at one end edge side, a guide roller 15 that comes into contact with the other end surface of the flange 13, and a flange. The driving roller 16 that comes into contact with one edge of the flange 13a and exerts a traveling driving force from the frictional force, and the screw means 1 to the other edge of the flange 13a.
7, and a holding roller 18 that can be brought into and out of contact with each other.

Two drive rollers 16 are provided at appropriate intervals in the traveling direction. These two drive rollers 16 are connected to each other by a chain / sprocket mechanism 19
Is rotatably driven by an electric motor 20 directly connected to one roller, and the entire automatic continuous welding machine 1 can travel and move using the wind resistant ring 13 as a guide rail.

In using this device, first, the holding roller 18 of the traveling device 4 is fully opened, and the wind resistant ring 13 made of H-shaped steel is attached to the structure being assembled for reinforcement. Attach the automatic continuous welding machine 1 with the welding head 2 on the upper side. In this state, a tilting moment in the direction of the arrow M acts due to the position of the center of gravity of the machine body, and therefore the posture is stably maintained by the pressure contact force of the guide rollers 14 and 15 against the front and back surfaces of the flange 13a. To be done. Basically, a sufficient driving force can be obtained by the weight of the machine body, but by properly tightening the holding roller 18, it becomes possible to travel with further play.

By the way, in the mounting relationship between the wind resistant ring 13 and the automatic continuous welding machine 1 shown in FIG.
If it is under the wind resistant ring 13 as a traveling rail, downward welding can be supported, and the welding head 2 is the wind resistant ring 1.
If it is on the upper side of 3, it can support upward welding. The position may be adjusted appropriately by using a counter weight or the like, and the positional relationship between the wire supply reel 3 and the welding head 2 with respect to the frame 6 of the traveling device 4 may be reversed. It may be configured as.

Furthermore, if the angle of the welding torch 7 is set to 45 degrees, fillet welding can be performed.

[0015]

As described above, according to the present invention, the reinforcing ring provided for temporarily assembling the steel plates when constructing a structure such as a tank, silo, and chimney is used as a traveling rail of an automatic continuous welding machine. You can Therefore, it is not necessary to separately install a dedicated rail, which is a great effect in reducing the number of steps. Moreover, since the reinforcing ring is usually attached near the seam, it also serves as a member for preventing welding distortion.
