Welding device feed cart {MOVING CART FOR WELDING EQUIPMENT}

The present invention relates to a welding apparatus transfer bogie to easily transfer a welding apparatus including welding equipment such as a welding machine, a cable, a mask in a field that requires a lot of manual welding in the shipbuilding industry.

In general, in welding ships with a large welding distance and a large amount of work, a welding machine such as an auto carriage has been used together with manual work.

1 is a view showing a manual welding device for a manual welding operation of the prior art disclosed in Figure 1 of the Utility Model 20-1999-0025517, Figure 2 is a view showing a manual welding operation state using the manual welding device of FIG. to be.

As shown in FIG. 1, the manual welding device includes a welding machine 1 equipped with wheels 2, a power supply cable 3, a welding holder 4, a holder wire 5, an earth wire 6, a welding rod 8, The worker W, including the mask M, is configured to weld all the welding devices by hand and weld the base materials 7 and 7 'manually.

 At the site where the ship is manufactured, a situation in which welding is performed at another place by moving the place after the welding operation frequently occurs. Therefore, as the work place moves, as shown in FIG. 2, the operator 1 welds the cable 1, the welding holder 4, the holder wire 5, the earth wire 6, the welding rod 8, and the mask M. And all drawings and equipment must be transferred to a new welding location.

In this case, the configuration of the manual welding device is too large for one person to transport, so that no one person can move several pieces of equipment at a time, moving the cable again to use the welding machine, and placing the cable on the cable holder for the passage of other workers. Since the welding work must be started after laying, there is a lot of time loss, and the incidence rate of musculoskeletal disease of the worker is increased due to the frequent transfer of the worker such as a welding machine, a holder, and the like.

In addition, the work efficiency decreases due to the continuous movement of the welding machine and the welding cable, the site is confused due to the complexity of the work site, and there is a possibility of an accident.

In order to improve such a problem, Korean Utility Model Publication No. 20-1999-0025517 fixes the plate to the ground, installs a vertical shaft with a lower end fixed to the center of the upper surface of the plate, installs a vertical cylindrical bar outside the vertical axis, and rotates the vertical axis. Interference is prevented by cables by installing a horizontal cylinder through the rotating bearing so that the lower end is in sliding contact with the upper end of the vertical cylindrical bar which can be rotated. Discloses a 'manual arc welder conveying device' which conveys a welding device so that welding can be carried out within the length of the horizontal bar.

However, the above-mentioned 'manual arc welder conveying device' of the prior art, because the plate is fixed to the ground, it is impossible to transfer the welding device to any place other than the area near the rotation radius of the horizontal bar, the welding work area is limited Problems may arise.

In addition, the Utility Model Registration No. 20-0231381 discloses a 'one-stop welding carrier', but the structure is complicated and large, it may cause difficulties in interpolation and management of welding devices, and cable puller work of the cable puller may not be easy. Has the problem.

In addition, in the case of a workplace for ship construction, as well as a variety of equipment in the field as shown in Figure 2, there are various obstacles such as lugs, through-pipes. Therefore, when the size of the truck is large, it may cause a problem that the transfer is not easy.

Therefore, the present invention is to solve the above-mentioned problems of the prior art, a welding apparatus transporting bogie which allows to transport a welding machine, a cable, a welding holder, a holder wire, an earth wire welding rod, a mask and drawings and various equipment at once. It aims to provide.

In addition, the present invention is another object of the present invention to provide a welding apparatus transfer bogie that can easily unwind the cable and transfer the entire welding apparatus at once.

 In addition, another object of the present invention is to provide a welding apparatus transfer bogie capable of lifting the bogie.

The welding apparatus feed cart of the present invention for achieving the above object, a bogie unit having a bogie on which a plurality of wheels are mounted; and a fixed shaft fixed to the upper surface of the bogie and the vertical shaft can be moved up and down. And a support shaft portion having a movable shaft coupled to the support shaft; and a cable pulling portion mounted to the support shaft portion; and a roller portion mounted to an upper end of the movable shaft in a state where a plurality of rollers are mounted to smooth the cable unwinding. It is characterized in that the configuration.

The trolley portion is characterized in that a plurality of compartments divided into a plurality of compartments formed by a plurality of partition jaw on the upper surface of the trolley.

In the support shaft portion, the gear box mounted inside the fixed shaft; And,

Recreational gear is mounted in the gear box to be moved up and down, one end is fixedly attached to the moving shaft; and a pinion gear for meshing with the rack gear to convey the up and down gear; and a lifting to rotate the pinion gear The handle; characterized in that it further comprises a cable lifter comprising a.

The stopper for stopping the rotation of the lifting handle is formed on the outer surface of the support shaft portion from which the lifting handle protrudes.

The roller portion is characterized in that the roller is attached to the outer periphery of each rod through which the cable passes in a grid-like rod shape to smooth the winding or winding of the cable.

The roller unit may include: a central rod coupled to an upper end of the fixed shaft; and side rods connected to both ends of the central rod; and both ends coupled to opposite ends of the spaced side rods, and a horizontal roller rotatably coupled to an outer circumferential surface thereof. And a plurality of horizontal rods; and a plurality of vertical rods protruded vertically from both ends of the horizontal rods and having a vertical roller rotatably coupled to an outer circumferential surface thereof.

The welding apparatus transport cart of the present invention having the above-described configuration reduces the number of hours by allowing the welding machine, the cable, the welding holder, the holder wire, the earth wire welding rod, the mask and drawings and various equipments to be transferred at once, thereby reducing the work efficiency of the welding operation. It provides the effect of significantly reducing the incidence of musculoskeletal disorders of the welding worker.

In addition, the present invention can be moved up and down the cable pulled by the shanghai transport, it is easy to unwind or wind the cable to provide an effect to facilitate the cable arrangement work.

In addition, the present invention maintains a state in which the cable pulled portion is integrally mounted to the support shaft portion, the cable is always kept in a state of arrangement, as in the prior art, the cable is prevented from complicating the workplace, the welding work efficiency and work It provides the effect of further improving safety.
