Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 4 A fire-fighting water tank welding auxiliary equipment includes a base 1, an external stabilizing mechanism 4, an internal stabilizing mechanism 5 and a horizontal adjustment seat 3 installed on an external supporting device.

The welding gun 7 adopts the existing technology and can be adaptively adjusted in position within a certain range.

[0033] The middle part of the water tank is composed of multiple tank bodies welded together. After the welding of the middle part of the water tank is completed, the head and tail cover parts are welded to the ends of the tank body to form a water tank. The state of the water tank before assembly welding is referenced. Figure 4 (a), the state of the water tank after assembly and welding is shown in Figure 4 (b).

[0034] The tank body is placed on the support mechanism 2 through a sling, and the support mechanism 2 supports the bottom of the tank body and the front and rear side walls; the horizontal positions of the external stabilizing mechanism 4 and the internal stabilizing mechanism 5 are adjusted through the horizontal adjustment seat 3.

[0035] Before welding the two tank bodies, the external stabilizing mechanism 4 is adjusted to the outside of the welding position, and the internal stabilizing mechanism 5 is adjusted to the inside of the welding position. At the same time, the anti-deformation mechanism 6 is driven to preheat the front and rear positions of the welding point. The external stabilizing mechanism 4 and the internal stabilizing mechanism 5 can increase the stability of the welding gun 7 during welding.

[0036] Before welding the head and tail covering parts and the tank body, the covering parts are placed close to the side of the tank body through a sling, the external stabilizing mechanism 4 is adjusted to the outside of the welding position, and the internal stabilizing mechanism 5 is adjusted to the vertical side of the head and tail covering parts. The external stabilizing mechanism 4 can increase the stability of the welding gun 7 during welding, and the internal stabilizing mechanism 5 and the supporting mechanism 2 cooperate to support the head and tail covering parts.

[0037] During welding, the water storage tank assembly is driven to roll by the supporting mechanism 2 to cooperate with the welding gun 7 to perform an annular welding operation.

[0038] Reference Figures 1 to 3The supporting mechanism 2 includes arc guide rails 22 correspondingly opened on the left and right sides of the top wall of the base 1, a supporting assembly 21 for supporting the bottom of the water tank assembly, a side support member 24 for supporting the front and rear sides of the water tank assembly, and a side support assembly 23 for supporting the left and right sides of the water tank assembly after transfer; the front and rear parts of the top wall of the base 1 are fixedly connected with a plurality of equidistantly distributed side support members 24, and the side support member 24 is composed of a support frame 2 fixedly connected to the base 1 and a roller 4 rotatably connected to the top of the support frame 2.

[0039] Reference Figure 2 , Figure 3 and Figure 5 The supporting assembly 21 includes a bidirectional motor 211, and the bidirectional motor 211 is symmetrically installed in the middle of the top wall of the base 1. The left output end and the right output end of the bidirectional motor 211 are fixedly connected with a roller group 212. The roller group 212 consists of two coaxially connected rollers 1 on the left and right, and the side walls of the leftmost and rightmost rollers 1 are coaxially connected with rollers 213.

[0040] Reference Figure 2 , Figure 3 and Figure 5 A side support assembly 23 is provided on the arc guide rail 22, and the side support assembly 23 includes a sliding seat 231. The sliding seat 231 is slidably connected to the arc guide rail 22 through an electric slider. The top wall of the sliding seat 231 is slidably connected to a side support member 232. The side support member 232 consists of a support frame 1 slidably connected to the sliding seat 231 and a roller 3 rotatably connected to the top of the support frame 1. An adjusting screw 233 is threadedly connected to the sliding seat 231, and the support frame 1 is threadedly connected to the adjusting screw 233 through an inverted L-shaped plate.

[0041] The tank bodies of the two water storage tanks are placed on the top of the base 1 through the sling, and the bottom walls of the tank bodies are close to the top walls of the corresponding front and rear roller groups 212, such as Figure 5 As shown in (a), the initial position of the side support assembly 23 is flush with the side support member 2 24, and the front and rear side walls of the tank body are in close contact with the side walls of the roller 3 of the side support assembly 23 and the roller 4 of the side support member 2 24. The roller group 212, the side support assembly 23 and the side support member 2 24 cooperate to support the tank body from the bottom and the front and rear directions. During welding, the roller group 212 is driven to rotate by the bidirectional motor 211, thereby driving the tank body to rotate for annular welding. In order to increase the friction force so that the roller group 212 can stably drive the tank body to rotate, a rubber layer can be set on the outside of the roller 1, and similarly, a rubber layer can be set on the outside of the roller 3.

[0042] Reference Figure 2 and Figure 6The external stabilizing mechanism 4 includes an external stabilizing component 42 for increasing the stability of the welding gun 7 during welding and a horizontal moving frame 41 for driving the external stabilizing component 42 to move horizontally.

[0043] Reference Figure 6 and Figure 7 The external stabilizing component 42 includes a hydraulic rod 421, and the top wall of the horizontal moving frame 41 is installed with the hydraulic rod 421. The top wall of the output end of the hydraulic rod 421 is fixedly connected with an upper fixed rod 422, and the front and rear ends of the upper fixed rod 422 are hinged with a connecting rod 423; a telescopic rod 424 is hinged between the side walls of the two connecting rods 423 close to each other and the front and rear side walls of the corresponding horizontal moving frame 41, and the bottom end of the connecting rod 423 is fixedly connected with an external stabilizing roller 425.

[0044] Reference Figure 3 and Figure 6 The internal stabilization mechanism 5 includes an internal stabilization component 52 for increasing the stability of the welding gun 7 during welding and a horizontal movable frame 51 for driving the internal stabilization component 52 to move horizontally. The horizontal adjustment seat 3 is connected to the horizontal movable frame 51 through an electric slider for sliding left and right.

[0045] Reference Figure 6 to Figure 7 The internal stabilization component 52 includes a hydraulic rod 521, and the bottom wall of the horizontal movable frame 51 is installed with the hydraulic rod 521. The bottom wall of the output end of the hydraulic rod 521 is fixedly connected with a lower fixed rod 522, and the front and rear ends of the lower fixed rod 522 are hinged with connecting rods 523; telescopic rods 524 are hinged between the top walls of the two connecting rods 523 and the front and rear side walls of the corresponding horizontal movable frame 51, and the bottom end of the connecting rod 523 is rotatably connected with an internal stabilization roller 525.

[0046] Reference Figure 6 , Figure 8 and Fig. 9 The anti-deformation mechanism 6 includes a welding adjustment frame 61, the bottom wall of the horizontal moving frame 1 41 and the top wall of the horizontal moving frame 2 51 are fixedly connected with the welding adjustment frame 61, the welding gun 7 is slidably connected to the welding adjustment frame 61 through an electric slider, and the horizontal moving frame 1 41 and the horizontal moving frame 2 51 are provided with slots for the welding gun 7 to move; the bottom wall of the welding adjustment frame 61 on the horizontal moving frame 1 41 and the top wall of the welding adjustment frame 61 on the horizontal moving frame 2 51 are both symmetrically fixed with heat conducting plates 62, the heat conducting plate 62 is composed of two heat conducting plates symmetrically distributed front and back, and a plurality of heating elements 63 are installed inside the heat conducting plate 62.

[0047] The outer stabilizing mechanism 4 and the inner stabilizing mechanism 5 are adjusted to the corresponding positions where the two tank bodies are closely attached to each other, the top wall of the output end of the hydraulic rod 421 moves downward, the upper fixed rod 422 moves downward, the connecting rod 423 and the telescopic rod 424 rotate adaptively, the telescopic rod 424 extends, and the connecting rods 423 move away from each other, and the connecting rod 423 drives the outer stabilizing roller 425 to approach the outer wall of the tank body and supports the end of the horizontal movable frame 41 from the front and rear directions.

[0048] The bottom wall of the output end of the hydraulic rod 521 moves downward, the lower fixed rod 522 moves downward, the connecting rod 523 and the telescopic rod 524 rotate adaptively, the telescopic rod 524 extends, and the connecting rods 523 move away from each other. The connecting rod 523 drives the inner stabilizing roller 525 to approach the inner wall of the tank body and supports the end of the horizontal movable frame 51 from the front and rear directions.

[0049] The horizontal moving frame 1 41 and the horizontal moving frame 2 51 drive the heat conducting plate 62 to move to the corresponding positions close to the two tank bodies where they are tightly attached to each other. The heat conducting plate 62 is located in the front and rear areas of the welding position. The two heat conducting plates of the heat conducting plate 62 are located on both sides of the weld. The heating element 63 increases the temperature of the heat conducting plate 62. The corresponding heat conducting plates 62 inside and outside heat the front and rear areas of the welding position to slow down the cooling speed, thereby reducing the shrinkage difference caused by rapid cooling, and at the same time helping to slowly release the residual stress generated during the welding process and reduce the risk of deformation.

[0050] The welding adjustment frame 61 supports the welding gun 7. The welding gun 7 on the upper welding adjustment frame 61 and the welding gun 7 on the lower welding adjustment frame 61 perform bidirectional synchronous welding on the welding position from both the external and internal directions to ensure that the forces on each part are balanced and to avoid deformation caused by unidirectional stress concentration.

[0051] When the tank body rolls and the welding gun 7 performs welding operations, the outer stabilizing roller 425 and the inner stabilizing roller 525 roll along the outer wall and the inner wall of the tank body, the outer stabilizing component 42 supports the horizontal moving frame 1 41, and the inner stabilizing component 52 supports the horizontal moving frame 2 51. The stability of the welding gun 7 during welding is increased through the multi-point support structure. The outer stabilizing component 42 and the inner stabilizing component 52 cooperate with the supporting mechanism 2 to perform multiple stabilizations on the tank body from the up and down directions and the inside and outside directions, respectively, to prevent discontinuity in the weld and to avoid weakening the strength of the weld due to discontinuity in the weld and reducing its bearing capacity.

[0052] Before welding the head and tail sealing parts of the water storage tank to the tank body, place the sealing parts on roller 213, which supports the bottom, and rotate the adjusting screw 233 until it disengages from the sliding seat 231, thereby releasing the relatively fixed relationship between the side support part 1 232 and the sliding seat 231, so that the side support part 1 232 can slide and move on the sliding seat 231 later, and adaptively adjust according to the positions of the head and tail sealing parts.

[0053] like Figure 5 As shown in (b), the sliding seat 231 is driven by the electric slider to slide on the arc guide rail 22 to the corresponding left and right tops of the base 1. When the sliding seat 231 drives the side support member 232 to move to the vertical side wall of the cover member, the adjusting screw 233 is rotated into the sliding seat 231, and the sliding seat 231 and the side support member 232 are relatively fixed; the horizontal moving frame 2 51 is moved to the vertical side wall of the cover member that fits the processing position, and the inner stabilizing roller 525 is rotated around the connecting rod 2 523 until the rolling surface fits the vertical side wall of the cover member at the processing position. The horizontal moving frame 2 51, the inner stabilizing roller 525 and the roller 3 provide multi-point support for the vertical side wall of the cover member at the processing position.

[0054] The horizontal movable frame 1 41 is slid to drive the external stabilizing assembly 42 to the welding position and adjusted, and the welding process is performed through the welding gun 7 on the external stabilizing mechanism 4, and the roller 213 drives the cover part at the processing position to rotate synchronously with the tank body to perform annular processing.

[0055] It should be noted that when welding the first cover, an external welding robot can pass through the tank body to weld the inside of the cover. When welding the second cover, the welding robot can be moved to the inside of the tank body through an inspection hole (not shown in the figure) or other appropriate position provided on the tank body to weld the inside of the corresponding cover.

[0056] Reference Figure 1-Figure 9 The specific operation steps of the fire-fighting water tank welding auxiliary equipment are as follows: when welding the two tank bodies of the water tank, the tank body is placed on the support mechanism 2 through a sling, and the roller group 212, the side support assembly 23 and the side support member 24 cooperate to support the tank body from the bottom and the front and rear directions; the external stabilization mechanism 4 and the internal stabilization mechanism 5 are adjusted to the corresponding welding position, driving the heat conduction plate 62 to be located in the front and rear areas of the welding position, and heating the front and rear areas of the welding position; the external stabilization assembly 42 and the internal stabilization assembly 52 increase the stability of the welding gun 7 during welding through a multi-point support structure; during welding processing, the roller group 212 is driven by the bidirectional motor 211 to rotate and drive the tank body to rotate for circular welding, and the two welding guns 7 perform bidirectional synchronous welding on the welding position from the outside and the inside.

[0057] When welding the tank body and the head and tail covering parts of the water storage tank, the head and tail covering parts are placed on the supporting mechanism 2 through the sling, the roller 213 supports the bottom of the covering part, the side support member 232 is adjusted to fit the vertical side wall of the covering part, the horizontal movable frame 2 51 and the internal stabilizing component 52 are moved to fit the vertical side wall of the covering part in the processing position, and the covering part is supported and stabilized by multi-point support; the horizontal movable frame 1 41 slides to drive the external stabilizing component 42 to the welding position, and drives the heat-conducting plate 62 to be located in the front and rear areas of the welding position, and heats the front and rear areas of the welding position. During the welding process, the roller group 212 and the roller 2 213 are driven by the bidirectional motor 211 to rotate to drive the tank body and the covering part for circular welding.
