[0029] As Figures 1 to 5 shown, the present utility model provides a carbon dioxide gas shielded welding device for railway embedded parts, including:

[0030] The equipment shell 1 has a rectangular groove 2 opened on the right side of the bottom of the equipment shell 1, and limiting grooves 3 are opened on the front and rear sides of the bottom end of the equipment shell 1 and are located on the right side of the rectangular groove 2;

[0031] A fixing mechanism is arranged at the bottom of the equipment shell 1;

[0032] Among them, the fixing mechanism includes a pneumatic cylinder 24. The pneumatic cylinder 24 is fixedly installed in the middle of the bottom of the equipment shell 1. A moving block 4 is fixedly installed on the right side of the pneumatic cylinder 24. The outer surface of the moving block 4 is movably connected to the inside of the rectangular groove 2. Diagonal rods 5 are hinged to the front and rear sides of the bottom of the moving block 4. The other ends of the diagonal rods 5 are hinged to vertical rods 6.

The right side of the clamping plate 7 is movably connected to the right side of the inner cavity of the equipment shell 1. The left and right movement of the moving block 4 will cause the clamping plate 7 to move back and forth.

[0033] When the pneumatic cylinder 24 starts to operate, it will cause the moving block 4 to move horizontally to the left under the limiting action of the rectangular groove 2, and cause the two diagonal rods 5 to start to move. At this time, under the limiting action of the limiting grooves 3, the two vertical rods 6 will drive the two clamping plates 7 to move horizontally towards each other, and finally the fixing effect on the gas cylinder will be achieved.

[0034] Among them, a transverse groove 8 is opened at the bottom of the right side of the inner cavity of the equipment shell 1. A limiting block 9 is movably connected to the inside of the transverse groove 8. The left side of the limiting block 9 is fixedly connected to the right side of the clamping plate 7.

[0035] When the clamping plate 7 moves, it will drive the limiting block 9 to move horizontally back and forth under the limiting action of the transverse groove 8.

[0036] Among them, a mounting plate 10 is fixedly installed at the bottom of the equipment shell 1, and a rotating plate 11 is hinged to the right side of the top of the equipment shell 1.

[0037] When the rotating plate 11 is rotated and opened, the gas cylinder can be replaced.

[0038] Among them, a connecting plate 12 is fixedly installed on the right side of the bottom of the equipment housing 1, a driving motor 13 is fixedly installed on the right side of the connecting plate 12, and the other end of the output shaft of the driving motor 13 is fixedly sleeved with a threaded rod 14.

[0039] When the driving motor 13 starts to operate, it will cause the threaded rod 14 to rotate.

[0040] Among them, the left end of the threaded rod 14 penetrates through the connecting plate 12 and extends to the inner surface of the mounting plate 10 and is movably sleeved with the inner surface of the mounting plate 10, and a rectangular block 15 is threadedly sleeved on the outer surface of the threaded rod 14.

[0041] When the threaded rod 14 rotates, it will cause the rectangular block 15 to move left and right.

[0042] Among them, a chute 17 is opened at the bottom end of the equipment housing 1, a connecting block 16 is movably connected inside the chute 17, and the bottom of the connecting block 16 is fixedly connected to the top of the rectangular block 15.

[0043] When the rectangular block 15 moves, it will drive the connecting block 16 to move horizontally left and right under the limiting action of the chute 17.

[0044] Among them, a connecting rod 18 is hinged to the bottom end of the rectangular block 15, and the other end of the connecting rod 18 is hinged to a first rectangular plate 19.

[0045] When the rectangular block 15 moves to the right, it will cause the connecting rod 18 to move and make the first rectangular plate 19 move downward.

[0046] Among them, second rectangular plates 20 are fixedly installed on both sides of the first rectangular plate 19, the number of the second rectangular plates 20 is two, and rollers 21 are movably installed at the front and rear ends of the two second rectangular plates 20.

[0047] Such a design enables the operator to drive the equipment through the rollers 21 for overall movement.

[0048] Among them, vertical grooves 23 are opened at the bottom ends of both sides inside the cavity of the mounting plate 10, a third rectangular plate 22 is movably connected inside the vertical grooves 23, the number of the third rectangular plates 22 is two, and the two third rectangular plates 22 are respectively fixedly installed on the outer sides of the two second rectangular plates 20.

[0049] When the first rectangular plate 19 moves, it will drive the second rectangular plate 20 and the third rectangular plate 22 to move vertically downward under the limiting action of the vertical grooves 23.

[0050] Among them, the number of the limiting blocks 9 is two, the sizes of the two limiting blocks 9 are the same, and the outer surfaces of the two limiting blocks 9 are smooth.

[0051] Such a design makes the movement of the limit block 9 inside the horizontal groove 8 smoother.

[0052] The working principle and usage process of the present utility model are as follows:

[0053] First, when the gas in the gas cylinder is exhausted and the gas cylinder needs to be replaced, rotate and open the rotating plate 11, and then start the air cylinder 24, which will cause the moving block 4 to move horizontally to the right under the limiting action of the rectangular groove 2, and cause the two inclined rods 5 to move. At this time, under the limiting action of the limiting groove 3 and the horizontal groove 8, the two vertical rods 6 will drive the two clamping plates 7 and the two limit blocks 9 to move horizontally away from each other together. At this time, the fixing effect on the gas cylinder will be released, achieving the purpose of facilitating the disassembly and assembly of the gas cylinder, improving the efficiency of the operator in disassembling and assembling the gas cylinder, and reducing the labor intensity of the operator.

[0054] When the device needs to be moved, start the driving motor 13, which will cause the threaded rod 14 to rotate, and cause the rectangular block 15 to drive the connecting block 16 to move horizontally forward under the limiting action of the sliding groove 17, and cause the connecting rod 18 to move. Thus, the first rectangular plate 19 will drive the second rectangular plate 20, the roller 21, and the third rectangular plate 22 to move vertically downward under the limiting action of the vertical groove 23. When the third rectangular plate 22 moves to the bottom end of the vertical groove 23, the roller 21 will completely leave the inside of the mounting plate 10. At this time, the operator can push the device housing 1, and the roller 21 will drive the whole device to move, achieving the purpose of facilitating transportation. At the same time, there is no need for the operator to hold it by hand, reducing the labor intensity of the operator, and the roller 21 can be completely retracted into the inside of the mounting plate 10, improving the stability of the device during welding operations.

[0055] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
