[0042] like Figure 4 , Figure 5 and Figure 6As shown, the support assembly 2 includes a plurality of sliding mechanisms 25, which are all fixed on the connecting mechanism 23, and the sliding mechanisms 25 include running wheels 251, which are arranged on the slide rail 21; at least one sliding mechanism 25 includes a driving motor 253, which is connected to the running wheels 251 to drive the running wheels 251 to rotate. The running wheels 251 connected to the driving motor 253 are driven to rotate by the driving motor 253, so that the placement platform 22 moves along the radial direction of the spherical tank, so as to facilitate welding, testing and grinding of spherical tanks of different diameters.

[0043] In addition, the support assembly 2 may include two slide rails 21 , which are parallel and spaced apart from each other, and at least one sliding mechanism 25 is disposed on each slide rail 21 , thereby improving the stability of the movement of the placement platform 22 .

[0044] Preferably, two sliding mechanisms 25 may be provided on each slide rail 21, wherein one sliding mechanism 25 includes a driving motor 253, and the other sliding mechanism 25 does not include a driving motor 253.

[0045] Optionally, the sliding mechanism 25 includes a box body 252 and a rotating shaft, and the box body 252 is welded or bolted to the connecting mechanism 23. The rotating shaft is connected to the box body 252 and is located inside the box body 252. The output shaft of the driving motor 253 is connected to the rotating shaft. The running wheel 251 is arranged on the rotating shaft, and the running wheel 251 is located inside the box body 252. The box body 252 is connected to the connecting mechanism 23, and the fixing between the sliding mechanism 25 and the connecting mechanism 23 can be achieved, so that the placement platform 22 can slide along the slide rail 21 under the drive of the sliding mechanism 25.

[0046] like Figure 5 and Figure 8As shown, a notch 254 is provided on the box body 252 so that the slide rail 21 can pass through the notch 254. The slide rail 21 includes a support member 211, a mounting member 212 and a stop member 213. The support member 211, the mounting member 212 and the stop member 213 are all in sheet shape. The two ends of the stop member 213 are respectively connected to the support member 211 and the mounting member 212, and the stop member 213 is perpendicular to the support member 211 and the mounting member 212. The mounting member 212 can be fixed on the placement surface, and the support member 211 and the part of the stop member 213 are located in the notch 254 of the box body 252. The walking wheel 251 is arranged on the upper surface of the support member 211 and can slide along the support member 211. An abutment member 26 can be fixed on the outer wall of the box body 252, and the abutment member 26 abuts against the stop member 213. When the running wheel 251 slides along the supporting member 211, the limiting member 213 slides along the abutting member 26, thereby guiding the movement of the running wheel 251. Optionally, the abutting member 26 may be "L" shaped, and the abutting member 26 may be fixed to the box body 252 by welding.

[0047] Preferably, two abutting members 26 are disposed on the box body 252 , and the two abutting members 26 abut against two opposite sides of the limiting member 213 , respectively.

[0048] Optionally, among the multiple sliding mechanisms 25 arranged on one slide rail 21 , only the box body 252 included in one sliding mechanism 25 may be provided with the abutment member 26 , or the box bodies 252 included in the multiple sliding mechanisms 25 may all be provided with the abutment member 26 .

[0049] In addition, the support assembly 2 also includes a guardrail 27, which can be fixed to the upper surface of the placement platform 22 by bolts, and the guardrail 27 is located on the side of the placement platform 22 facing the center of the spherical tank, thereby playing a role in safety protection.

The placement member 28 can be in the shape of a plate, and a placement groove 281 is provided on the placement member 28. Part of the petal 1 of the spherical tank can be arranged in the placement groove 281, so that the placement member 28 can support the petal 1 of the spherical tank. The placement member 28 can slide along the slide rail 21, so as to adjust the position of the placement member 28, so that the placement member 28 can support spherical tanks of different diameters. The locking member can fix the placement member 28 to the slide rail 21, so as to lock the position of the placement member 28. At present, the support for the petal 1 of the spherical tank is achieved by a support member 211 welded on the ground support structure. For spherical tanks of different diameters, the ground support structure needs to be re-welded, and the efficiency is low when replacing spherical tanks of different diameters. However, the present application realizes the support of the petal 1 of the spherical tank by a placement member 28 that can slide along the slide rail 21, which improves the efficiency when replacing spherical tanks of different diameters.

[0051] Optionally, the support assembly 2 further includes a slide groove 29, which is connected to the bottom of the placement member 28, and the slide groove 29 is arranged on the slide rail 21, so that the placement member 28 can move along the slide rail 21.

[0052] Preferably, each slide rail 21 is provided with a placement member 28 to support the petals 1 of the spherical tank at different positions to ensure the stability of the support of the spherical tank.

[0053] In the embodiment of the present application, the spherical tank flap welding auxiliary device includes a plurality of support assemblies 2, and the plurality of support assemblies 2 are arranged at intervals along the circumference of the spherical tank.

[0055] Furthermore, the spherical tank flap welding auxiliary device also includes a pedal 3, and the two ends of the pedal 3 are respectively placed on two placement platforms 22 included in two adjacent support assemblies 2. In this way, by providing multiple pedals 3 and multiple placement platforms 22, a similar ring-shaped bearing surface can be formed, and the operator moves to different placement platforms 22 and pedals 3 to facilitate welding, testing and grinding of different positions of the spherical tank.

[0056] The spherical tank petal welding auxiliary device of the present application can be applied to spherical tanks of different diameters, without the need to repeatedly build and dismantle scaffolding, thereby improving the efficiency of welding, testing, and polishing of spherical tanks.
