Detailed implementation manners

[0016] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the present utility model.

[0017] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0018] Please refer to Figure 1 and Figure 4 A welding device for processing steel-lined tetrafluoro storage tanks provided by an embodiment of the present utility model includes:

[0019] A wheel column 1 and a universal wheel 2, the universal wheel 2 is installed on the wheel column 1, one end of the wheel column 1 away from the universal wheel 2 is fixedly connected with a support ring 3, the support ring 3 is provided with a groove, the inner wall of the groove opened by the support ring 3 is provided with a wheel groove, and both the wheel column 1, the universal wheel 2 and the support ring 3 are provided with two; a distance adjustment mechanism 4, which is fixedly connected with the two support rings 3, and the distance adjustment mechanism 4 is used to pull the two support rings 3 closer to or away from each other for distance adjustment; an electric telescopic rod 5, which is fixedly installed inside the support ring 3, and a pressing block 6 is installed on the electric telescopic rod 5, and the electric telescopic rod 5 is used to push the pressing block 6 to press and fix the storage tank placed in the support ring 3; a welding mechanism 7, which is installed at the groove opened by the support ring 3, and the power output end of the welding mechanism 7 can be closely attached to the position of the tank body where the storage tank is needed to weld the storage tank.

[0020] When using the welding device for processing the steel-lined tetrafluoro storage tank, first place the two storage tanks to be welded into the support ring 3, align the positioning grooves and the abutting blocks 6 opened on the storage tanks, and turn on the electric telescopic rod 5. The electric telescopic rod 5 can drive the abutting blocks 6 to move inwards, so that the storage tanks can be pressed and fixed. After fixing, turn on the distance adjustment mechanism 4. The distance adjustment mechanism 4 can drive the wheel columns 1, the universal wheels 2 and the support ring 3 on both sides to approach each other. Until the two storage tanks are close to each other, turn on the welding mechanism 7. The welding mechanism 7 can be close to the position of the storage tank to be welded and weld the storage tank.

[0021] As Figure 1 shown, as a preferred embodiment of the present invention, the distance adjustment mechanism 4 includes: a support sleeve 41, which is arranged between the two wheel columns 1. A power member 42 is fixedly arranged in the support sleeve 41, and the output shaft of the power member 42 is fixedly connected with a first bevel gear 43; a lead screw 44, there are two of them, and the mutually remote ends are rotatably connected to the inner wall of the support sleeve 41. The two lead screws 44 have opposite thread directions and the mutually approaching ends are fixedly connected with a connecting rod 45. A second bevel gear 46 meshing with the first bevel gear 43 is fixedly arranged on the connecting rod 45; a guide rod 47, both ends of which are fixedly connected to the inner wall of the support sleeve 41. A push plate 48 threaded with the lead screw 44 is sleeved on the guide rod 47, and the push plates 48 are distributed on both sides of the connecting rod 45; a push rod 49, one end of which is fixedly connected to the push plate 48, and the other end of the push rod 49 is arranged outside the support sleeve 41 and fixedly connected to the support ring 3.

[0022] When controlling the mutual approach of the two support rings 3, turn on the power member 42. The power member 42 is specifically a motor. The output shaft of the power member 42 drives the first bevel gear 43 to rotate. The first bevel gear 43 drives the second bevel gear 46, the connecting rod 45 and the lead screw 44 to rotate. The rotation of the lead screw 44 can make the push plates 48 and the push rods 49 on both sides approach each other along the guide rod 47. The mutual approach of the push rods 49 on both sides can drive the support rings 3 on both sides to approach each other, so as to drive the two storage tanks to approach each other and be close to each other.

[0023] As Figure 1 , Figure 3 and Figure 4 shown, as a preferred embodiment of the present invention, the welding mechanism 7 includes: a toothed ring 71, which is fixedly installed on the inner wall of the groove opened on the support ring 3. The toothed ring 71 meshes with a moving component 72 slidably arranged in the wheel groove. The moving component 72 can move in a circular motion along the toothed ring 71 and the wheel groove; a protective sleeve 73, which is arranged between the two support rings 3. A linkage component 74 is installed on the protective sleeve 73. Both ends of the linkage component 74 are arranged outside the protective sleeve 73 and fixedly connected to the moving component 72; a hydraulic push rod 75, which is fixedly connected to the protective sleeve 73. A welding torch 76 for welding the storage tank is fixedly arranged on the hydraulic push rod 75.

[0024] As Figure 4 shown, as a preferred embodiment of the present utility model, the moving assembly 72 includes: a guide wheel 721, which is slidably arranged in the groove formed in the support ring 3, a wheel frame 722 is installed on the guide wheel 721, and both ends of the linkage assembly 74 are fixedly connected to the wheel frame 722; a driving member 723, which is installed on the wheel frame 722, a moving gear 724 that is rotatably installed in the wheel frame 722 is fixed to the output shaft of the driving member 723, and the moving gear 724 meshes with the toothed ring 71.

[0025] During welding, the hydraulic push rod 75 is turned on. After the hydraulic push rod 75 drives the welding torch 76 to be close to the position of the storage tank that needs to be welded, the driving member 723 is turned on. The driving member 723 drives the moving gear 724 to rotate, and the moving gear 724 can drive the wheel frame 722 and the guide wheel 721 to move along the toothed ring 71 and the wheel groove. Thus, the protective sleeve 73 can be driven by the linkage assembly 74 to rotate circumferentially around the storage tank, and then drive the welding torch 76 to rotate circumferentially around the position of the storage tank that needs to be welded, realizing the rapid welding of the storage tank.

[0026] As Figure 3 shown, as a preferred embodiment of the present utility model, the linkage assembly 74 includes: a linkage gear 741, which is rotatably installed in the protective sleeve 73, linkage racks 742 are engaged on both sides of the linkage gear 741, a linkage plate 743 is fixedly connected to the two linkage racks 742 on both sides, and a through hole for the linkage rack 742 to pass through is formed in the linkage plate 743; two linkage rods 744, and the mutually approaching ends of the two are fixedly connected to the linkage plate 743, and the mutually remote ends of the two linkage rods 744 are fixedly connected to the wheel frame 722.

[0027] When the two support rings 3 approach each other, the two support rings 3 can drive the two linkage rods 744, the linkage plate 743 and the linkage racks 742 to move, thereby driving the linkage gear 741 to rotate. Since the linkage gear 741 is rotatably installed in the protective sleeve 73, the protective sleeve 73 can always be in the middle position, so that the hydraulic push rod 75 and the welding torch 76 are in the middle position, ensuring that the welding torch 76 can weld the storage tank smoothly and avoiding the position deviation of the welding torch 76.

[0028] 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, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
