Description

Cart for moving welding machine {Cart for moving welding machine}

The present invention relates to a cart for transporting a welder, and relates to a cart for transporting a welder that can easily transport devices necessary for a welding operation using a single cart.

In general, welding refers to an operation of joining different metals together. Welding work is mainly performed at construction sites or workshops, and specifically, welding work uses a variety of bulky and heavy equipment such as a welding machine body, a wire supply device, and a gas cylinder.

Since welding equipment is mainly used for joining bulky and heavy metal objects due to the nature of the device, it is difficult to easily move a target to be welded. Workers have to carry the welding gun connected to the welding equipment and carry out the work, but the welding equipment is bulky and heavy, so it is not easy to move. Accordingly, during the welding operation, a transfer device capable of moving the welding equipment and performing the welding operation is used.

Such a conventional welding machine transfer device had a feature of loading welding equipment on a wheeled cart and operating the cart using a handle. At this time, in the welding equipment, a power connection line receiving power is extended. The welding equipment may additionally require a welding machine body and a device such as a wire feeder for supplying a wire for welding to the welding machine body. In this case, a power supply is required to the main body of the welding machine, and a separate power supply is also required to the wire feeder. That is, when a plurality of devices are loaded on a cart for transporting a welder, power supply lines are stretched and entangled with each other, which interferes with work. In addition, there is also a cable extending from the welding machine body, and there is a problem in that various types of wires interfere with work during work.

The upper plate 200 is installed to be spaced apart from the top of the plate 100 and the laser welder is mounted on the upper surface, and the upper plate 200 is installed in the spaced apart space between the lower plate 100 and the upper plate 200 Supports and is exposed to the side and is formed on the outer side of the side wall 310 excluding the feeder unit accommodating portion 320 for accommodating the feeder unit, and the lower plate ( Gas cylinder fixture 400 including a lower support 410 extending outwardly from 100 to support the lower portion of the gas cylinder C, and an upper support 420 extending upward from the upper plate 200 to support the side of the gas cylinder. ), a handle 220 extending from the upper plate 200 on the opposite side of the gas cylinder fixture 400, and installed on the side of the housing 300, connected to an external power source to supply power to the laser welding machine and the feeder unit It includes a power connector 500 to.

The cart 1 for transporting a welder according to the present invention is a cart used for laser welding and has a feature that can accommodate all devices used for laser welding, such as a laser welder, a feeder unit, and a gas cylinder. In particular, the cart 1 for transporting a welder according to the present invention has a storage unit capable of accommodating a laser welder, a feeder unit, and a gas cylinder in each partitioned space and further accommodating tools or protective equipment necessary for additional work ( 300). That is, the present invention can accommodate and stably transport all the equipment necessary for laser welding at once, so that the welding operation of the operator can be safely and efficiently assisted.

The cart 1 for transporting the welder largely includes a lower plate 100, an upper plate 200, and a storage part 300 connecting them.

The lower plate 100 has a plate shape and is disposed horizontally with the ground to support the lower part of the cart 1 for transporting the welder. The lower plate 100 may be formed in the form of a metal plate capable of withstanding a heavy load since the accommodating part 300 is coupled to the top. Furthermore, the lower plate 100 is formed in the shape of a square plate, so that many items can be efficiently loaded. In addition, the lower plate 100 is formed to be freely movable by attaching the transport wheel 600 to the lower surface. The transfer wheel 600 attached to the lower plate 100 is a caster wheel 610 capable of rotating a wheel shaft, and the caster wheel 610 freely rotates according to the traveling direction of the lower plate 100, and the lower plate ( 100) can be transported.

The upper plate 200 is spaced apart and coupled to the top of the lower plate 100, and functions to mount a laser welder on the top surface. The upper plate 200 is formed in the same plate shape as the lower plate 100 and is disposed parallel to the top of the lower plate 100 . In other words, the lower plate 100 and the upper plate 200 are spaced side by side so as to overlap each other in a plate shape of the same size, and are disposed horizontally with the ground. An upper surface of the upper plate 200 is formed with a projection 210 protruding to partition a space in which the laser welder is seated. The locking jaw 210 may be disposed along the edge of the region where the laser welder is seated, and furthermore, it may be installed at each corner of the region where the laser welder is seated to prevent the laser welder from leaving. The upper plate 200 is supported by the housing 300 positioned between the lower plate 100 and the upper plate 200 .

The accommodating part 300 is interposed between the lower plate 100 and the upper plate 200 and coupled to the top surface of the lower plate 100 to support the lower end of the upper plate 200 . In addition, the storage unit 300 forms a storage space separated from the outside by forming a side wall 310 in the space between the lower plate 100 and the upper plate 200 . The storage space of the storage unit 300 can be opened and closed in various ways such as a sliding door method or a sliding door method, and can accommodate tools or safety equipment necessary for work. The accommodating part 300 forms a side wall 310 along an area excluding the feeder unit accommodating part 320, which is a space in which the feeder unit is accommodated. That is, the accommodating part 300 forms the side wall 310 along the outer surface between the upper plate 200 and the lower plate 100 and the recessed inner surface of the feeder unit accommodating part 320 . The feeder unit accommodating portion 320 is a space for accommodating a box-shaped feeder unit, and is formed by indenting inwardly between the lower plate 100 and the upper plate 200. The feeder unit accommodating portion 320 is a space communicating with the outside, and is formed by indenting portions of two adjacent side surfaces including one vertex of the upper plate 200 . Accordingly, the accommodating part 300 supports the upper plate 200 with three vertices excluding the feeder unit accommodating part 320 . That is, one vertex of the accommodating part 300 supporting the upper plate 200 may be empty by the feeder unit accommodating part 320, and the upper plate 200 may be supported by the remaining three vertices.

Meanwhile, the gas cylinder fixture 400 is formed on the outer side of the accommodating part 300 and functions to accommodate at least one gas cylinder. Since the gas cylinder is long and heavy, it is not suitable to be seated on the lower plate 100 or the upper plate 200, and may be seated on a separate gas cylinder fixture 400. The gas cylinder fixture 400 includes a lower support 410 supporting a lower portion of the gas cylinder and an upper support 420 supporting a side portion of the gas cylinder.

The lower support 410 extends from one side of the lower plate 100, forms a step with the lower plate 100, and extends to a lower height to support the lower end of the gas cylinder. That is, the lower support 410 extends in parallel with the lower plate 100 but has a lower height than the lower plate 100, so that a heavy gas cylinder can be raised or lowered more conveniently. In addition, the lower support 410 extends from the side that does not overlap with the feeder unit accommodating portion 320 and is formed. In particular, fixing wheels 620 are mounted on both ends of the lower support 410 to more stably support the weight of the gas cylinder. The fixed wheel 620 has a larger diameter than the caster wheel 610 and has a fixed axial direction, and serves to assist the caster wheel 610.

The upper support 420 protrudes vertically from the upper plate 200 to support and fix the side of the gas cylinder seated on the lower support 410 . The upper support 420 fixes the side of the gas cylinder at a specific height higher than the top surface of the upper plate 200 . The upper support 420 includes a pedestal 421 that protrudes to the side contacting the gas cylinder and adheres to the outer circumferential surface of the gas cylinder, and a fixing strap 422 that is detachably coupled to the pedestal 421 . The pedestal 421 forms a concavely recessed curved surface to correspond to the outer circumferential surface of the gas cylinder. The curved surface of the pedestal 421 may be in close contact with a part of the side surface of the gas cylinder. The pedestal 421 has a structure in close contact with the gas cylinder and may be formed of a material having strength capable of supporting the side of the gas cylinder. The remaining side of the pedestal 421 that is not covered by the curved surface may be wrapped and fixed using a fixing strap 422 .

The fixing strap 422 is wrapped around the pedestal 421 in a string shape having both ends coupled to the pedestal 421 and serves to wrap and fix the side of the remaining gas cylinder. Both ends of the strap 422 are fixed to the pedestal 421 and are formed in a structure capable of coupling and separating in one section. In other words, the fixing strap 422 may be separated or combined into two straps based on both ends fixed to the pedestal 421 and connected as one strap. In addition, since the length of the strap 422 is adjustable, the length of the strap 422 wrapped around the gas cylinder can be reduced to adjust the fixing force of the gas cylinder, and gas cylinders of various sizes can be fixed.

On the other hand, the handle 220 extends from the upper surface of the upper plate 200 to the opposite side of the upper support 420 and serves to easily transport the welder transfer cart 1. The handle 220 is installed on the side where the caster wheel 610 is mounted, and the axial direction of the caster wheel 610 can be easily adjusted by manipulating the handle 220 . The operator can move the cart 1 for transporting the welder by pushing the handle 220 in various angles, such as back and forth, left and right. In addition, a welding gun holder 240 is installed on one side of the handle 220 . The handle 220 may be formed in various ways in the shape of a handle generally used for a cart.

The welding gun holder 240 is installed on one side of the handle 220 and serves to mount the welding gun. The welding gun holder 240 is formed with a through-hole 241 having a size capable of penetrating only the tip of a wide welding gun. The welding gun holder 240 can safely mount the welding gun by penetrating the tip of the welding gun, which is at risk of burns due to high temperature during laser welding, through the through hole 241 .

In addition, the fiber cradle 230 is installed in a section of the upper plate 200 adjacent to the welding gun cradle 240 and functions to mount an optical fiber extending from the wire welder. The fiber cradle 230 is composed of a vertical shaft 231 extending vertically from the upper plate 200 and a guide member 232 formed at an end of the vertical shaft 231 to guide the optical fiber in the transverse direction. The vertical shaft 231 is formed to be able to adjust the length in the vertical direction and has a structure that supports one section of the optical fiber, and can be adjusted to a height suitable for work. The guide member 232 functions to horizontally mount the optical fiber along the longitudinal direction. The guide member 232 has grooves recessed in the transverse direction along the longitudinal direction to accommodate the optical fiber. In addition, the guide member 232 is capable of 360° rotation and angle fixation with respect to the vertical axis 231, so that it can be freely manipulated according to the operator's convenience. The guide member 232 guides the optical fiber horizontally for one section and rotates the optical fiber in a desired direction so that a worker can more easily manipulate the welding gun coupled to the end of the optical fiber. Furthermore, the welding gun receives the welding wire from the feeder unit. At this time, the welding wire is discharged from the feeder unit. The feeder unit is located in the feeder unit accommodating part 320 at the lower end of the handle 220, and the welding wire is discharged to the lower part of the handle 220.

Meanwhile, the power connection unit 500 is formed on one side of the housing unit 300 to supply power to the laser welding machine and the feeder unit. In particular, the power connector 500 has a structure capable of receiving external power at once and distributing it to a plurality of devices. The power connection unit 500 has a structure that can simplify a complicated wiring structure into a single power supply line, and can prevent safety accidents that may occur due to twisting of the line. Furthermore, the power connection unit 500 is formed by being exposed to the outside of the housing unit 300, so that power can be easily connected. When an external power source is connected to the power connection unit 500, the operator can power on both the laser welding machine and the feeder unit. It is readily available and can be used easily.
