Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a torch-side wire feeder of a welding device for welding a so-called deck plate, which is used in constructions, vehicles, and other structures.

Recently, in semi-automatic arc welding work, long-length conduit cables are often used in order to expand the work range. For example, as shown in FIG. 7, one end of the first conduit cable A is connected to the control cable C connected to the controller B and the base side wire feeding device D is connected.
Supported by the consumable electrode wire fed by The other end of the first conduit cable A is connected to the torch side wire feeder E, and the second conduit cable F is provided between the torch side wire feeder E and the welding torch G. It is connected. In this type of welding device, the first and second conduit cables A and F usually have a length of several tens of meters and a length of about 3 to 6 m.

When welding a deck plate using this device, the torch-side wire feeding device E is placed on the deck plate P, and while the operator moves in the groove direction of the deck plate P, that is, in the X direction, the welded portions are sequentially welded. Was. In this case, as shown in FIGS. 7 and 8, since the torch side wire feeding device E is located in the groove of the deck plate P, the worker pulls the conduit cable F as welding progresses, The position of the torch side wire feeding device E was moved in the X direction. After the welding work of the predetermined groove of the deck plate in the X direction is completed, the welding part is moved to the next welding part separated in the Y direction. In most cases, the handle Et provided on the torch side wire feeding device E is used. Then, after carrying the torch-side wire feeding device E near the next welded portion, the second welding operation was performed. In this way, when the welding position is significantly different in the direction orthogonal to the groove of the deck plate P, that is, in the Y direction,
Carrying the torch-side wire feeding device E to the vicinity of the next welded part has been standardized as a welding work procedure.

<Problems to be solved by the invention> However, due to the recent change in the number of welding workers, the conventional welding work procedures tend to be ignored, which causes damage to the welding equipment and, as a result, the welding work efficiency. Was getting worse. That is, the worker does not like to carry the torch side wire feeding device E by using the handle Et, and regardless of the welding position, the torch side wire feeding device E is operated via the conduit cable F. Trying to pull to the side.

By the way, when the torch-side wire feeding device E is pulled in the Y direction, the torch-side wire feeding device E falls or is caught by the uneven surface of the deck plate P.
Ignoring this situation, the worker uses the welding torch G or the torch-side wire feeder E with the conduit cable F.
Welding torch G, to continue or repeat the pulling work of
There is a problem that the conduit cable F or the torch side wire feeding device E is damaged. Of course, in this case, not only the damaged portion had to be repaired, but also the welding work efficiency was poor due to the interruption.

<Means for Solving the Problem> The configuration of the present invention includes a base side wire feeding device, a torch side wire feeding device, a torch side wire feeding device and a welding torch which are connected to a control device, respectively. Also, in the torch-side wire feeding device in the deck plate welding apparatus that is connected by the second conduit cable, the maximum groove size of the deck plate is wider than b1, and has a bottom surface wider than b1 and rises upward at both wide end portions. It is characterized in that the guard formed with the portion is detachably supported.

<Embodiment> The present invention will be described in detail below with reference to an illustrated embodiment.

1 to 4, reference numeral 1 denotes a guard having a wide bottom surface which is detachably supported by the torch-side wire feeding device E, and the width: W and the length: L of the guard 1 are a deck plate; P. When the maximum groove top dimension of is b1 W> b
1, L> b1. In addition, the widthwise ends of the guard 1 are respectively provided with rising portions 101, 10 extending upward.
1 is formed. In addition, in the case of illustration, as shown in FIG.
2, 102 are formed. Reference numeral 2 denotes a waterproof cover that is openably and closably supported by the guard 1 and covers the torch-side wire feeding device E. For example, the waterproof cover 2 has one end locked to the guard 1 and the other end with respect to the guard 1. Supported so that it can be locked and released.

By the way, since the torch-side wire feeder E is generally provided with a handle Et for transportation, for example, the handle Et is attached and the guard 1 is attached instead. In this way, the torch-side wire feeding device E to which the guard 1 is attached is placed on the upper surface of the deck plate P, and welding is performed in the state shown in FIG. That is, the torch-side wire feeding device E is appropriately pulled to the operator side via the conduit cable F to perform the work.

By the way, the width of the guard 1 is shown as W> b1. However, if the width of the guard 1 is unnecessarily widened, the workability becomes worse, so that W = b1 + (50 to 100) mm is preferable as a rough guide. . in this case,
When the torch side wire feeder E is rotated, the torch side wire feeder E may be fitted in the groove of the deck plate P. However, in the guard 1, the rising portions 101, 101
Since the torch side wire feeding device E remains only tilted as shown by the chain double-dashed line in FIG. 4, the torch side wire feeding device E is further pulled by pulling the conduit cable F. It can be easily moved in the desired direction.

It is preferable to provide the rising portions 102, 102 at the front and rear of the guard 1. However, since the length of the torch-side wire feeding device E is usually long, the length of the guard 1: L is the torch-side wire feeding device. Rise 10 as the length of E approaches
2,102 can be omitted. Further, the front and rear parts of the torch-side wire feeding device E are respectively connected with the conduit cables A and F. Depending on the mounting condition of the conduit cables A and F, the deck plate P of the torch-side wire feeding device E is connected. When the inclination into the groove is relaxed, the rising portions 102, 102 can be removed.

In most cases, the deck plate welding work is performed outdoors, but if the guard 1 is provided with the waterproof cover 2 that covers the torch side wire feeder E as described above, the torch side is protected from rainwater and dust. Since the wire feeding device E is protected, the device does not need to be stored when the work is interrupted due to a sudden change in weather or when normal work is completed, and the torch side wire feeding is performed by opening and closing the waterproof cover 2 during welding work. Appropriate operations required for the device E, such as welding wire insertion and welding wire feeding adjustment, can be performed.
The waterproof cover 2 is easy to handle if it is formed of a flexible member, but it is preferable that the waterproof cover 2 be formed of a fixed member in order to prevent an external force from acting on the torch-side wire feeding device E.

Further, in general, since the deck plate welding work is often performed at a high place, when the torch-side wire feeding device E is unloading or unloading from the deck plate,
By removing the gart 1 and attaching the handle Et to the torch side wire feeding device E again, the carrying becomes easy.

FIGS. 5 and 6 are views showing another embodiment of the present invention, in which a handle Et and a case of the torch-side wire feeding device E are provided with mounting holes and mounting screws, respectively, and the handle Et is attached to the handle Et. The guard 1 can be attached to and detached from the torch-side wire feeding device E without being removed.

Therefore, the torch-side wire feeding device can be transported using the handle Et with the guard 1 attached. Of course, when the guard 1 is bulky and becomes an obstacle, the handle Et can be used only by removing the guard 1. Further, since the handle Et is not removed, there is no risk of losing the handle Et. Of course, although not shown, a waterproof cover for covering the torch-side wire feeding device E can be provided.

Of course, the guard and the waterproof cover according to the present invention may be structured to include the entire torch-side wire feeding device.

<Effects of the Invention> As is clear from the above description, the torch-side wire feeding device for welding the deck plate according to the present invention has a bottom surface that is wider than the maximum groove dimension of the deck plate;
Also, since the guards with upward rising portions are detachably supported at both wide ends, welding work is performed with the torch-side wire feeding device placed on the deck plate, and the The torch-side wire feeding device can be appropriately attracted to the operator side via the cable. In this case, since the guard has the rising portions 101, 101, the torch-side wire feeding device only tilts with respect to the groove of the deck plate even under the worst condition. Therefore, by pulling the conduit cable, The torch-side wire feeding device can be easily moved in the desired direction. That is, as in the conventional case, the torch side wire feeding device has a defect caused by being fitted in the groove of the deck plate, particularly, the torch side wire feeding device is inserted through the conduit cable in a direction orthogonal to the groove of the deck plate. The disadvantages of pulling by means of the device are eliminated by the device according to the present invention, and efficient welding work can be performed.
