Description

Technical Field

[0001] The utility model provides a welding tool for processing a waterwheel tank body, and relates to the technical field of welding. Background Art

[0002] A water tanker is a vehicle specially designed to transport liquids. It is usually designed as a closed container for loading and transporting various liquids, such as water, chemicals, food raw materials, etc. This type of vehicle is widely used in urban water supply, fire fighting, industrial production, and agricultural irrigation.

[0003] When processing the tank body of the waterwheel, the steel plate is cut and rolled into a circle, and then the longitudinal seam is welded to form a tubular tank body segment, and then the multiple tank segments are welded into a tank. During butt welding, a roller frame is used to support the tank body and drive the two tank sections to rotate. Due to the huge size and heavy weight of the tank body, the tank body cannot maintain a perfect circle, the top of the tank body will sink, and there will be misalignment and gaps at the joint. Especially when the tank bodies on both sides rotate at the same time, the misalignment and gaps will further increase, resulting in the top welder being unable to align well with the tank body joint during welding, affecting the welding accuracy. To this end, we propose a welding tool for processing waterwheel tank bodies. Utility Model Content

[0020] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figures 1 to 5 The utility model provides a welding tool for processing a waterwheel tank body, comprising at least four reinforcing positioning tools 1 applied to the joint of the tank body, the reinforcing positioning tool 1 comprising a supporting cross frame 4, a tensioning side plate 9 arranged on the inner side of both ends of the supporting cross frame 4, a fixing seat 5 fixedly connected to the end of the tensioning side plate 9, an electromagnet 3 installed on the inner side of the fixing seat 5, and a tensioner 10 arranged between the supporting cross frame 4 and the tensioning side plate 9, the supporting cross frame 4 is a hollow structure, the tensioning side plate 9 is slidably connected to the supporting cross frame 4, and an extrusion block 17 is fixedly connected between the tensioning side plates 9. Specifically, when the reinforcing positioning tool 1 is used, the electromagnets 3 on both sides are respectively adsorbed on both sides of the joint of the tank body, and then the tensioning side plate 9 is further pulled toward the inner side of the supporting cross frame 4 by the tensioner 10, and the tensioning side plate 9 drives the tank body to approach each other through the electromagnet 3, so that the joint is tightly fitted, and by using multiple reinforcing positioning tools 1, a fixing effect is formed at the joint of the tank body, which can effectively prevent it from being misaligned.

[0022] Furthermore, if Figure 4 , Figure 5 As shown, the inner side of the supporting cross frame 4 is provided with a limiting groove 18 along the length direction, and the side of the tensioning side plate 9 is fixedly connected with a limiting block 16, and the limiting block 16 is slidably placed in the limiting groove 18, and the limiting blocks 16 on both sides are respectively against the ends of the limiting groove 18. Specifically, through the arrangement of the limiting block 16 and the limiting groove 18, the tensioning side plate 9 cannot be arbitrarily moved left and right in the supporting cross frame 4, and only under the strong pulling of the tensioner 10 can the tensioning side plate 9 be driven to squeeze the extrusion block 17 inward, so that the tensioning side plate 9 moves into the supporting cross frame 4.

[0023] Furthermore, if Figure 3 As shown, the tensioner 10 includes an articulated seat 12 fixed to the supporting cross frame 4, a hand lever 11 articulated to the articulated seat 12, a tensioning rod 13 articulated to the hand lever 11, a cushion block 15 fixed to the tensioning side plate 9, and a tensioning seat 14 fixed to the cushion block 15. The tensioning rod 13 is U-shaped, and the tensioning seat 14 is provided with a hook groove matched with the tensioning rod 13. Specifically, as Figure 3 As shown, the hand lever 11 can be opened by bending the hand lever 11 clockwise, and the tension rod 13 is loosened and can be removed from the tension seat 14. Conversely, the tension rod 13 is first put on the hook groove, and then the hand lever 11 is bent counterclockwise until Figure 3 In this state, the tensioner 10 can be tightened. During the tightening process of the tensioner 10, the tensioning side plate 9 can be driven to move into the supporting cross frame 4.

[0024] Furthermore, if Figure 2As shown, it also includes a central support ring 2, on which a hydraulic cylinder 6 is fixedly connected, and the telescopic end of the hydraulic cylinder 6 is fixedly connected to the bottom surface of the supporting cross frame 4, and support rods 8 are symmetrically fixedly connected to both sides of the central support ring 2, and moving wheels 7 are installed at the ends of the support rods 8. Specifically, the central support ring 2, the support rods 8 and the moving wheels 7 constitute a bracket structure, which can support and fix multiple strengthening and positioning tools 1, and facilitate unified movement. The strengthening and positioning tools 1 are driven by the hydraulic cylinder 6 to contact the inner wall of the tank body and play a supporting role, which is conducive to the tank body to maintain its shape and the top is not easily deformed.

[0025] Furthermore, if Figure 2 As shown, the end surface of the electromagnet 3 is an arc surface. The arc-shaped end surface can better fit the inner wall of the tank.

[0026] Working principle: The reinforcing positioning tooling 1 is driven by the moving wheel 7 to move to the joint of the tank body, so that the electromagnets 3 are placed on both sides of the joint, and the hydraulic cylinder 6 is started to drive the reinforcing positioning tooling 1 to move, so that the electromagnets 3 are in contact with the inner wall of the tank body. The electromagnets 3 are energized and adsorbed on the inner wall of the tank body. At the same time, the tensioning side plates 9 on both sides are tightened toward the inner side of the supporting cross frame 4 through the tensioner 10, so that the joint of the tank body is more tightly connected. By using multiple reinforcing positioning tooling 1, a fixing effect is formed at the joint of the tank body, which can effectively avoid its misalignment. At the same time, the reinforcing positioning tooling 1 is supported by the hydraulic cylinder 6, thereby supporting the tank body, which is conducive to the tank body maintaining its shape and the top is not easy to deform. In subsequent welding, the joint of the tank body is not easy to deform, misaligned and have gaps, thereby ensuring the accuracy of welding.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
