Description

Technical Field

[0001] This utility model relates to the field of metal tank welding technology, specifically to an internal support tool for welding metal tanks. Background Technology

[0002] Metal tanks are devices used to store liquids or gases, typically made of metals such as steel, and generally have a large capacity. Large metal tanks are widely used in many industrial sectors, including but not limited to the chemical, petroleum, and food manufacturing industries. Due to their large size, these metal tanks are usually difficult to cast in one piece and are often made by welding multiple sheet metal parts. During the welding process, internal support is often required, which necessitates the use of internal support tools to meet the welding requirements.

[0003] Conventional internal bracing tools are generally pneumatically or electrically driven. When using such tools for internal bracing, the support blocks on multiple support sides need to be adjusted one by one, resulting in a long preparation time during the internal bracing process and low overall installation efficiency. Utility Model Content

[0004] To address the problem of low installation efficiency of existing internal support tools, this utility model provides an internal support tool for welding metal tanks, which reduces preparation time during the internal support process and improves installation efficiency.

[0005] The technical solution is as follows: an internal support tool for welding metal tanks, comprising an installation rod and multiple internal support plates, each used to support the interior of the metal tank. The internal support plates are connected to the installation rod via a connecting assembly. The installation rod comprises an upper movable column, a lower movable column, and a bidirectional telescopic rod. The upper and lower ends of the bidirectional telescopic rod are respectively connected to the bottom end of the upper movable column and the top end of the lower movable column. The connecting assembly comprises two symmetrically arranged installation sleeves, which are fixedly sleeved to the upper and lower movable columns respectively. The upper and lower installation sleeves are rotatably connected to one end of multiple connecting rods, and each connecting rod connected to the upper or lower installation sleeve corresponds to one of the internal support plates. The other end of each connecting rod is rotatably connected to an internal support plate.

[0006] Furthermore, a first fixing seat is fixedly installed at equal angles on the outer side of the mounting sleeve, a second fixing seat is fixedly installed on the inner support plate, and the two ends of the connecting rod are rotatably connected to the first fixing seat and the second fixing seat respectively through a rotating shaft.

[0007] Furthermore, the contact surface between the inner support plate and the metal tank is provided with anti-slip grooves.

[0008] Furthermore, a bottom fixing component is fixedly connected to the bottom end of the lower movable column.

[0009] Furthermore, an extension guide rail is fixedly installed at an equal angle at the top of the outer side of the upper movable column, and the extension guide rail is connected to an auxiliary clamping assembly, which is used to clamp the top of the metal can.

[0010] Furthermore, the extension guide rail is movably engaged with a guide block, the guide block moves back and forth relative to the extension guide rail, and the bottom end of each guide block is fixedly connected to an extension frame, the bottom end of which is connected to the middle of the top of the inner support plate.

[0011] Furthermore, an extension rod is fixedly connected to the side of the guide block away from the upper movable column, and an inner clamping plate is movably connected to the side of the extension rod away from the guide block. An outer clamping plate is provided on the side of the inner clamping plate away from the extension guide rail. The inner clamping plate and the outer clamping plate can rotate in the vertical direction, and an elastic telescopic rod is installed at the top position between the inner clamping plate and the outer clamping plate.

[0012] Furthermore, both the inner and outer clamping plates have arc-shaped guide slopes at their bottom ends.

[0013] Beneficial effects: This utility model, by opening the bidirectional telescopic rod and controlling the shortening of its upper and lower ends, reduces the distance between the upper and lower movable columns and brings them closer together. The connecting rod then deflects outward, applying a thrust to the inner support plate. Multiple inner support plates, all subjected to the thrust from the inside, move away from each other until they contact the inner surface of the metal tank, thus completing the rapid support process for the tank. During use, only the length of the bidirectional telescopic rod needs to be controlled to quickly achieve the inner support process of the tank, reducing adjustment time and improving overall welding efficiency.

[0014] In addition, as the inner support plate moves outward, it can also drive the auxiliary clamping assembly to move, so that it can move to the top of the tank and clamp the tank, thereby ensuring the stability of the device. Attached Figure Description

[0019] like Figures 1 to 4 As shown in this embodiment, an internal support tool for welding metal cans includes an installation rod and an internal support assembly 5. The internal support assembly 5 includes multiple internal support plates 505, each used to support the interior of the metal can. The contact surface between the internal support plate 505 and the metal can is provided with an anti-slip groove. The internal support plate 505 is connected to the installation rod via a connecting assembly. The installation rod includes an upper movable column 1, a lower movable column 2, and a bidirectional telescopic rod 4. The upper and lower ends of the bidirectional telescopic rod 4 are respectively connected to the bottom end of the upper movable column 1 and the top end of the lower movable column 2. The bidirectional telescopic rod 4 can be a bidirectional electric telescopic rod, or the upper and lower movable columns can be threadedly connected to the upper and lower ends of the telescopic rod. The upper and lower movable columns can move up and down by turning the telescopic rod. The bottom end of the lower movable column 2 is fixedly connected to a bottom fixing member 3, which can be a suction cup base 3 (or other components that can fix the lower movable column 2). To maintain its vertical structure, for example, by fixing it with screws, but this method increases the pre-welding preparation time; the connecting assembly includes two symmetrically arranged mounting sleeves 501, which are fixedly sleeved to the upper movable column 1 and the lower movable column 2 respectively (for example, sleeved on the movable column and then fixed to the movable column with screws). The upper and lower mounting sleeves are rotatably connected to one end of multiple connecting rods 504, and each connecting rod 504 connected to the upper or lower mounting sleeve 501 corresponds to an inner support plate 505. The other end of the connecting rod 504 is rotatably connected to the inner support plate 505. Specifically, a first fixing seat 502 is fixedly installed at equal angles on the outer side of the mounting sleeve 501, and a second fixing seat 503 is fixedly installed on the inner support plate 505. The two ends of the connecting rod 504 are rotatably connected to the first fixing seat 502 and the second fixing seat 503 respectively through a rotating shaft.

[0020] Before use, the device can be placed in the middle of the large tank to be welded using the suction cup base 3 at the bottom of the lower movable column 2, and fixed to the ground by adsorption. Then, by opening the bidirectional telescopic rod 4 and controlling the upper and lower ends of the bidirectional telescopic rod 4 to shorten, the distance between the upper movable column 1 and the lower movable column 2 decreases and they move closer to each other. The connecting rod 504 then deflects outward, and a thrust is applied to the inner support plate 505. At this time, multiple inner support plates 505 are subjected to the thrust from the inside, and they move away from each other until they contact the inner side of the large tank. This completes the rapid support process of the large tank, allowing the device to quickly achieve the inner support process of the tank by only controlling the length change of the bidirectional telescopic rod 4, reducing adjustment time and improving the overall welding efficiency.

[0021] In addition, an extension guide rail 6 is fixedly installed at an equal angle at the top of the outer side of the upper movable column 1. The extension guide rail 6 is connected to an auxiliary clamping component 7, which is used to clamp the top of the metal tank.

[0022] Specifically, the extension guide rail 6 is movably engaged with a guide block 701, which moves back and forth relative to the extension guide rail 6. An extension frame 703 is fixedly connected to the bottom of each guide block 701, and the bottom of the extension frame 703 is connected to the middle of the top of the inner support plate 505. An extension rod 702 is fixedly connected to the side of the guide block 701 away from the upper movable column 1. An inner clamping plate 704 is movably connected to the side of the extension rod 702 away from the guide block 701. An outer clamping plate 705 is provided on the side of the inner clamping plate 704 away from the extension guide rail 6. The inner clamping plate 704 and the outer clamping plate 705 can rotate vertically. An arc-shaped guide slope is provided at the bottom of the inner side of both the inner clamping plate 704 and the outer clamping plate 705. An elastic telescopic rod 706 is installed at the top between the inner clamping plate 704 and the outer clamping plate 705.

[0023] During the internal support process of the pipeline, the inner support plate 505 can move closer to the inner side of the tank, which simultaneously drives the extension frame 703 to move outward. At this time, the extension rod 702 also moves outward, simultaneously driving the inner clamping plate 704 and the outer clamping plate 705 to move outward. When the inner support plate 505 completes the internal support, the inner clamping plate 704 and the outer clamping plate 705 are located directly above the inner wall of the tank, completing the synchronous adjustment. The inner and outer clamping plates can be rotated downward to achieve the synchronous downward movement of the inner clamping plate 704 and the outer clamping plate 705. Relying on the action of the arc-shaped guide slope at the bottom of the tank's inner wall, the outer clamping plate 705 and the inner clamping plate 704 move away from each other. Relying on the elastic action of the elastic telescopic rod 706, they clamp the inner wall of the tank, thus completing the clamping process. By utilizing the internal support process of the tank, the auxiliary clamping component 7 is directly linked to complete the corresponding adjustment, so that the auxiliary clamping of the top of the tank can be achieved simultaneously while the internal support of the tank is completed, shortening the clamping process and improving efficiency.

[0024] This utility model provides an internal support tool for welding metal tanks, and its working principle is as follows:

[0025] Before use, the device needs to be placed in the middle of the large tank to be welded by using the suction cup base 3 at the bottom of the lower movable column 2, and then fixed to the ground by adsorption. After fixing, the multiple auxiliary clamping components 7 should be kept at the top of the large tank in the initial state.

[0026] When it is necessary to support the inner side of a large tank, the bidirectional telescopic rod 4 can be activated and the upper and lower ends of the bidirectional electric rod 4 can be shortened. At this time, the distance between the upper movable column 1 and the lower movable column 2 will decrease and they will move closer to each other. The connecting rod 504 will then deflect outwards, and a thrust can be applied to the inner support plate 505. At this time, multiple inner support plates 505 will be subjected to thrust from the inside and will move away from each other until they come into contact with the inner side of the large tank. This completes the rapid support process for the large tank.

[0027] During the internal support process of the tank, the inner support plate 505 can move closer to the inner side of the tank, which simultaneously drives the extension frame 703 to move outward. At this time, the extension rod 702 moves outward as well, and simultaneously drives the inner clamping plate 704 and the outer clamping plate 705 to move outward. When the inner support plate 505 completes the internal support, the inner clamping plate 704 and the outer clamping plate 705 are located directly above the inner wall of the tank, completing the synchronous adjustment. The inner and outer clamping plates can be rotated downward to achieve the synchronous downward movement of the inner clamping plate 704 and the outer clamping plate 705. Relying on the action of the inner wall of the tank on the bottom arc-shaped guide slope, the outer clamping plate 705 and the inner clamping plate 704 move away from each other. Relying on the elastic action of the elastic telescopic rod 706, it clamps the inner wall of the tank, thereby completing the clamping process.

[0028] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
