[0019] Example

[0020] like Figure 1-4As shown, in this embodiment, a tool for submerged arc welding of large cylinders of different specifications is mainly disclosed, which has a simple and reliable structure and includes a mounting plate 1 for connecting a lifting platform, a working platform 2 which can be extended out of the mounting plate 1 and is horizontally slidably connected to the mounting plate 1, a locking cylinder 11 is provided on the mounting plate 1, and a plurality of positioning cylinders 21 cooperating with the locking cylinder 11 are provided on the working platform 2, and the positioning cylinder 21 is connected to the locking cylinder 11 by a latch; it should be noted that when welding the cylinder, auxiliary equipment is usually used to stabilize the lying cylinder; the mounting plate 1 is connected to an existing lifting platform, such as an electric lifting platform vehicle. When in use, the tool is lifted to a suitable height by the lifting platform, and then the working platform 2 is horizontally slid so that the working platform 2 extends above the cylinder or extends and overlaps the outer wall of the cylinder, which is convenient for submerged arc welding operations, and the latch passes through the positioning cylinder 21 and is inserted into the locking cylinder 11 to achieve horizontal position fixation of the working platform 2, ensuring the stability and safety of the operation, and can adapt to the welding requirements of cylinders of different specifications and sizes, thereby improving operational flexibility.

[0021] Furthermore, in specific implementation, Figure 3 、 4 As shown, a slide groove 22 is provided under the above-mentioned working platform 2 provided in the embodiment of the present invention, a slide rail 12 is provided on the mounting plate 1, and pulleys 13 are respectively installed on both sides of the slide rail 12, and the pulleys 13 are abutted against the upper and lower ends of the inner wall of the slide groove 22; preferably, the cross-section of the slide groove 22 is C-shaped, and the opening of the slide groove 22 faces downward. Specifically, the pulley 13 is wrapped inside the slide groove 22, and the upper and lower ends of the inner wall of the slide groove 22 are abutted against the pulley 13. On the one hand, the working platform 2 can slide smoothly, and on the other hand, it can effectively prevent the working platform 2 from extending outward and overturning, thereby improving the stability and safety of the working platform 2.

[0022] Preferably, one end of the slide groove 22 is provided with a limit plate 23 that abuts against the end of the slide rail 12 to limit the extension of the work platform 2, so as to avoid safety hazards caused by excessive displacement and ensure safety during operation; the other end of the slide groove 22 is connected to a support wheel 24 for contacting the outer wall of the cylinder. On the one hand, when the work platform 2 is extended, it can overlap with the cylinder to play a supporting role and avoid the work platform 2 from being bent and deformed by force. On the other hand, when the work platform 2 retracts, the support wheel 24 is supported downward and outward, and can abut against the mounting plate 1 or the end of the slide rail 12 to play a retraction limit role.

[0023] Preferably, the pulleys 13 are arranged in a plurality and staggered up and down along the length of the slide rail 12, so that the force is evenly distributed and the service life of the device is extended.

[0024] Furthermore, in specific implementation, Figure 1 、 2As shown, the above-mentioned working platform 2 provided in the embodiment of the present utility model is provided with a guardrail 25; during operation, the operator needs to tie the safety belt to the guardrail 25 to prevent the operator from accidentally falling during the operation, thereby increasing the safety protection during the welding operation.
