When the prior device is in use, the mobile seat 6 is moved to the construction site by the universal wheel 4. According to the height of the construction personnel, the toggle rod 15 is pushed to move the clamping rod 12 out of the positioning socket 11 and the through-hole 13, and the height of the protective rod 7 is adjusted. The toggle rod 15 is loosened, so that the clamping rod 12 passes through the through-hole 13 and the positioning socket 11 under the resetting force of the elastic member 16, and the adjusted protective rod 7 is fixed to achieve the height adjustment of the protective rod 7, so that it is convenient for people of different heights to perform high-altitude welding operations.

[0031] The working principle of this embodiment:

[0032] Before standing welding, the device is moved to the welding position by the walking wheel 4. After moving to the welding position, the third motor 28 is controlled to start by the controller 3, and the third motor 28 drives the output shaft to rotate in the opposite direction. The output shaft of the third motor 28 drives the second drive shaft 31 to rotate in the opposite direction.

The third motor 28 is controlled to stop by the controller 3. At this time, the bottom end of the base frame 1 directly contacts the ground to improve the standing stability of the device.

[0033] During standing welding, the welder enters the standing frame 16 by crossing, and the assistant controls the second motor 22 to start through the controller 3, and the second motor 22 drives the output shaft to rotate forward, and the output shaft of the second motor 22 drives the first drive shaft 26 to rotate forward, and the first drive shaft 26 drives the two first worms 23 to rotate forward, and the two first worms 23 drive the two meshing first worm wheels 24 to rotate forward, and the two first worm wheels 24 drive the two screw rods 27 with limit plates to rotate forward, and during the forward rotation of the two screw rods 27 with limit plates, the two connected middle The middle hollow guardrails 12 move upward on the two screw rods 27 with limit plates, the two middle hollow guardrails 12 drive the two connected top guardrails 14 to move upward, the two top guardrails 14 drive the top rectangular frame 13 to move upward, the top rectangular frame 13 drives other connected top guardrails 14 to move upward, and other top guardrails 14 drive the connected middle hollow guardrails 12 to move upward in the corresponding bottom hollow guardrails 15 until they move to a suitable protection position, and the assistant controls the second motor 22 to stop through the controller 3, which is convenient and quick to adjust, saving time and effort;

[0034] During standing welding, the assistant controls the first motor 2 to start through the controller 3, and the first motor 2 drives the output shaft to rotate in the forward direction. The output shaft of the first motor 2 drives the intermediate screw 17 to rotate in the forward direction. During the forward rotation of the intermediate screw 17, the driving plate 38 moves on the intermediate screw 17 toward the direction of the two inner connecting plates 7, and the driving plate 38 drives the two lower guide blocks 39 to move in the same direction on the two lower guide rods 18.

During the tilting movement of the two outer connecting rods 40, the two inner connecting rods 43 are driven to tilt and move to lift the standing frame 16, so as to adjust the height of the standing frame 16. Until the height of the standing frame 16 is adjusted to a suitable position, the assistant controls the first motor 2 to stop through the controller 3, and the welder can perform welding operations at this time.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that:

Since a connecting spring 19 is provided between the welding tool box 21 and the storage slot 20, the welding tool box 21 can be automatically reset after the tools are taken out, thereby avoiding the problem of the welding tool box 21 being unable to be reset due to forgetting.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 2 is that:

[0043] The working principle of this embodiment:

[0044] If the welder finds that the required welding tools are not with him during the welding process, he can call the assistant to remind him, and the assistant takes the welding tools required by the welder and places them in the welding tool placement box 45. The welder rotates the handle 49 forward at a high place, and the handle 49 drives the rotating shaft 48 to rotate forward. During the forward rotation of the rotating shaft 48, the winding connecting rope 47 drives the welding tool placement box 45 to move up until the welding tool placement box 45 moves to a suitable position, stops rotating the handle 49, takes the welding tools, and rotates the handle 49 in the opposite direction to place the welding tool placement box 45 back on the placement plate 5.
