Description

Technical Field

[0001] The utility model relates to a submerged arc welding device, in particular to a rotatable submerged arc welding trolley. Background Art

[0002] Submerged arc welding is a welding method in which the arc burns under the flux layer. Submerged arc welding has the advantages of stable welding quality, no arc light and little smoke. It is the main welding method in the production of important steel structures such as box beams and columns.

[0003] The submerged arc welding machine can release flux along the weld through the flux box, and then bury the welding wire in the flux through the welding head, and finally energize the welding head to melt the welding wire to complete the welding of the weld. Generally, the submerged arc welding machine is set for the weld to be welded, so the submerged arc welding machine is not movable. In the prior art, some submerged arc welding trolleys can be moved so as to quickly move to the next weld, saving installation time.

[0004] In the existing submerged arc welding trolley, due to the different locations of the welds, the submerged arc welding trolley can only be moved by simply pushing the whole body to control the position of the welding head when the whole body moves, so that the welding head is directly above the weld. However, when adjusting the submerged arc welding trolley as a whole, due to its size, the submerged arc welding trolley is easily blocked by objects in the environment, especially in some narrow environments, the submerged arc welding trolley may not be able to move, which makes it difficult to adjust the position of the welding head. Moreover, when adjusting the submerged arc welding trolley as a whole, the user mainly adjusts the main part of the submerged arc welding trolley, which makes it difficult to align the welding head with the weld, and multiple adjustments are required, which is very troublesome.

[0031] refer to Figures 1 to 3 A rotatable submerged arc welding trolley according to a preferred embodiment of the utility model will be described in detail below. The rotatable submerged arc welding trolley includes a trolley body 10, a rotating component 20, a welding component 30 and a control component 40.

[0032] like Figure 1 and Figure 2 As shown, the trolley body 10 includes a chassis 11 and at least three moving parts 12, wherein the moving parts 12 are mounted on the chassis 11 so that the chassis 11 can move. The rotating assembly 20 is mounted on the trolley body 10 so that the rotatable submerged arc welding trolley can rotate.

[0033] As an example, the moving member 12 is implemented as a universal wheel.

[0034] The rotating assembly 20 includes a rotating member 21 and a driving member 22 . The driving member 22 is mounted on the chassis 11 . The rotating member 21 is driven by the driving member 22 to rotate.

[0035] By way of example, the drive element 22 is implemented as a drive motor.

[0036] like Figure 1 and Figure 2 As shown, the rotating member 21 includes a rotating body 211 and a connecting member 212. The top of the rotating body 211 forms a vertical portion 2111. The connecting member 212 is transversely mounted on the vertical portion 2111, and the welding assembly 30 is mounted on one end of the connecting member 212. The rotating body 211 is fixed to the chassis 11 and is drivably connected to the top of the driving member 22, so that the driving member 22 drives the rotating body 211 to rotate, thereby driving the connecting member 212 mounted on the vertical portion 2111 and the welding assembly 30 mounted on the connecting member 212 to rotate. In this way, the welding position can be adjusted without moving the trolley body 10 of the rotatable submerged arc welding trolley, so that in some narrow environments, the position of the welding point can be adjusted by rotating the welding assembly 30.

[0037] Preferably, a fixed portion 2112 is provided at the bottom of the rotating body 211, and a rotating disk 221 is provided on the driving shaft of the driving member 22. The rotating disk 221 is fixedly connected to the fixed portion 2112, so that when the driving member 22 is driven, the rotating disk 221 drives the fixed portion 2112 to rotate, thereby driving the rotating body 211 to rotate.

[0038] Preferably, the bottom surface of the rotating body 211 is the same as the upper surface of the chassis 11, and the cross-section of the upper and middle part of the rotating body 211 is smaller than the bottom surface of the rotating body 211, so as to form a smaller cylinder to reduce the volume of the rotating body 211, thereby reducing the production cost and the overall volume so as to adapt to narrow environments.

[0039] In one embodiment, the connecting member 212 is implemented as a telescopic cylinder. Since the welding assembly 30 is installed at one end of the connecting member 212, when the connecting member 212 is telescoped, the welding assembly 30 can be driven by the connecting member 212 to move laterally, so that the rotation radius of the welding assembly 30 changes, thereby enabling the rotatable submerged arc welding trolley to adjust more positions when the trolley body 10 does not move.

[0040] In another embodiment, the rotating assembly 20 further includes an adjusting member, which is used to adjust the rotation radius of the welding assembly 30. The adjusting member includes an adjusting drive, an adjusting screw and a slider, wherein the adjusting drive is mounted on the upright portion 2111. The adjusting screw is parallel to the connecting member 212, and one end of the adjusting screw is drivably connected to the adjusting drive so that the adjusting screw is driven to rotate. The slider is threadedly connected to the other end of the adjusting screw, the welding assembly 30 is mounted on the slider, and the welding assembly 30 is configured to slide on the connecting member 212, so that when the adjusting screw rotates, the welding assembly 30 slides along the connecting member 212, thereby adjusting the rotation radius of the welding assembly 30.

[0041] like Figure 1 and Figure 3 As shown, the welding assembly 30 includes a welding box 31, a welding head 32 and a welding wire 33, wherein the welding box 31 is installed at one end of the connecting member 212, and the welding head 32 has a wire feeding channel 3201, the wire feeding channel 3201 of the welding head 32 is connected with the welding box 31, and the welding head 32 can be powered. The welding wire 33 is movably installed in the welding box 31, and the welding wire 33 can be moved out of the welding head 32 by the welding box 31 through the wire feeding channel 3201 of the welding head 32, and abuts against the weld to be welded, so that when the welding head 32 is powered, the welding wire 32 melts and welds the weld.

[0042] Preferably, if Figure 3 As shown, the welding box 31 includes a box body 311, a wire feeding member 312 and a wire feeding drive member 313, wherein the box body 311 forms a box inner space 31101 and a wire feeding space 31102, and the box inner space 31101 is connected to the wire feeding space 31102 and the wire feeding channel 3201 of the welding head 32. The welding wire 33 is stored in the box inner space 31101 in a manner that it can be sent out of the box inner space 31101. The wire feeding member 312 is drivably connected to the wire feeding drive member 313, and the wire feeding member 312 and the wire feeding drive member 313 are installed in the wire feeding space 31102 in a manner that the welding wire 33 can be transmitted.

[0043] Preferably, the wire feeder 312 is implemented as a pair of rollers. The wire feeder drive 313 is implemented as a drive motor. The welding wire 33 is arranged to be clamped in the middle of the wire feeder 312. After the wire feeder drive 313 drives the wire feeder 312, the welding wire 33 is driven and then moves according to the rotation direction of the wire feeder 312.

[0044] Those skilled in the art can understand that, when welding, the welding wire 33 will be driven by the wire feeding component 312 driven by the wire feeding drive component 313, so that the welding wire 33 enters the wire feeding channel 3201 of the welding head 32 from the space 31101 in the box through the wire feeding space 31102, and then passes through the wire feeding channel 3201 to abut the weld that the user needs to weld.

[0045] Preferably, the welding assembly 30 also includes a flux box 34, the flux box 34 has a flux groove 3401 and a flux channel 3402, and one end of the flux channel 3402 is connected to the flux groove 3401, and the other end of the flux channel 3402 is connected to the end of the welding head 32 away from the welding box 31, so that the flux can be discharged from the flux groove 3401 through the flux channel 3402 from the end of the welding head 32 away from the welding box 31, so as to accurately cover the weld.

[0046] Those skilled in the art can understand that the flux required for submerged arc welding is placed in the flux tank 3401 before welding, and is discharged from the end of the welding head 32 away from the welding box 31 through the flux channel 3402 during welding. Since the end of the welding head 32 away from the welding box 31 will be above the weld during welding, the flux can cover the weld.

[0047] The control assembly 40 includes a main control box 41 and a control board 42. The main control box 41 is arranged on the side of the chassis 11, and the control board 42 is installed at an end of the connecting member 212 relatively far from the welding assembly 30. The main control box 41 and the control board 42 are connected in communication. The main control box 41 is controllably connected to the welding head 32, and the control board 42 is controllably connected to the driving member 22.

[0048] It can be understood by those skilled in the art that when the rotatable submerged arc welding carriage starts welding, the welding head 32 moves to the top of the weld, and after the flux passes through the flux channel 3402 and is discharged from the end of the welding head 32 away from the welding box 31 and covers the weld, the control board 42 controls the driving member 22 to drive, so that the rotating body 211 rotates, thereby adjusting the welding position of the welding head 32 to accurately weld the weld. Under the action of the welding box 31, the welding wire 33 abuts the weld through the wire feeding channel 3201 of the welding head 32, and the welding head 32 is energized under the control of the main control box 41, so that the portion of the welding wire 33 abutting the weld melts, and then fills the weld in cooperation with the flux to complete the welding.

[0049] Preferably, the trolley body 10 includes a protective component 13, and the protective component 13 includes a protective member 131, wherein the protective member 131 is installed on the top of the chassis 11, and the protective member 131 surrounds the side of the driving member 22 to protect the driving member 22 from the side.

[0050] Preferably, the protective member 13 also includes a first protective cover 132, which is installed on the outer side of the lower end of the rotating body 211 to protect part of the rotating body 211, and the first protective cover 132 is connected above the protective member 131 to surround the rotating body 211 and the protective member 131, so that the space between the rotating body 211 and the protective member 131 is closed to prevent the driving part of the driving member 22 from being affected by external foreign objects.

[0051] It is worth mentioning that the first protective cover 132 is fixed on the rotating body 211, and the first protective cover 132 and the protective member 131 are connected. Therefore, there may be a connection gap between the first protective cover 132 and the protective member 131, which may cause foreign matter from the outside to enter the first protective cover 132 through the connection gap.

[0052] More preferably, if Figure 2 As shown, the protective component 13 also includes a partition 133, which is fixedly installed on the top of the protective member 131, and the end of the partition 133 away from the protective member 131 abuts against the first protective cover 132 to separate the space between the first protective cover 132 and the driving member 22, so that external foreign matter cannot enter the space between the first protective cover 132 and the protective member 131 from the connecting gap between the first protective cover 132 and the protective member 131, thereby preventing foreign matter from affecting the operation of the driving member 22.

[0053] Preferably, the protection component 13 further includes a second protection cover 134 , which is installed on the outer side of the upper middle portion of the rotating body 211 to cooperate with the first protection cover 132 to fully protect the rotating body 211 .

[0054] Preferably, the protective member 13 also includes a wrapping member 135, which is installed at the top of the upright portion 2111 in a manner to protect the end of the rotating body 211, so that the top of the upright portion 2111 is wrapped by the wrapping member 135, thereby preventing the user from being stabbed by the top of the upright portion 2111.

[0055] As an example, the wrapping member 135 is made of rubber material.

[0056] Preferably, the rotating member 21 further includes a rotating handle 213, and the rotating handle 213 is installed on the outer side of the middle part of the rotating body 211. Since the moving part 12 is installed at the bottom of the chassis 11, the rotatable submerged arc welding trolley can be pushed by the user through the rotating handle 213, so that the rotatable submerged arc welding trolley can be quickly moved to another weld after completing a welding task.

[0057] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
