[0002] In related technologies, daily fuel tanks are containers used to temporarily store fuel during daily life or during the operation of specific equipment. Their use is becoming increasingly widespread. To monitor the fuel level within these tanks, a level gauge, such as a magnetic flap level gauge, is often installed. Leveraging the excellent sealing properties of magnetic flap level gauges, these gauges effectively prevent fuel leakage and volatilization, ensuring safety and environmental protection.

[0003] However, in the existing daily fuel tank production, after the main body of the fuel tank is welded, it is necessary to wait for the magnetic flap level gauge to be purchased before the positioning function of the magnetic flap level gauge can be used to weld the flange for connecting the magnetic flap level gauge at the corresponding position of the fuel tank. However, the procurement cycle of the magnetic flap level gauge is relatively long, which will affect the completion progress of the fuel tank, resulting in the inability to continue with the work such as rust prevention, leak testing, and painting of the fuel tank. In addition, the magnetic flap level gauge is easily damaged when welding the flange on the daily fuel tank, which will also cause unnecessary trouble. Utility Model Content

DETAILED DESCRIPTION

[0033] The following is a detailed explanation and description of the positioning welding tool for the daily oil tank level gauge flange provided by the utility model in conjunction with the drawings in the specification.

[0034] The utility model provides a positioning welding tool for the flange of a daily oil tank level gauge, such as Figure 1 As shown, the positioning welding tool includes: a sliding rod 40, two flange fixing plates and an adsorption component 30, etc.

[0035] like Figure 1-Figure 3As shown, the two flange fixing plates include a first flange fixing plate 10 and a second flange fixing plate 20. The first flange fixing plate 10 is slidably mounted above the slide rod 40. It is used to secure the level gauge flange and locate the installation position of the level gauge flange above the daily fuel tank. The second flange fixing plate 20 is slidably mounted below the slide rod 40. It is used to secure the level gauge flange and locate the installation position of the level gauge flange below the daily fuel tank. The adsorption assembly 30 is disposed in the middle of the slide rod 40 and is used to secure the slide rod 40 to the daily fuel tank by adsorption.

[0036] In this embodiment, after the level gauge flange is installed using the first flange fixing plate 10 and the second flange fixing plate 20, the slide rod 40 is adsorbed on the side wall of the daily fuel tank through the adsorption component 30, so that the slide rod 40 and the daily fuel tank are relatively fixed. Since the first flange fixing plate 10 can slide on the upper part of the slide rod 40 and the second flange fixing plate 20 can slide on the lower part of the slide rod 40, the corresponding flange fixing plates are adjusted to correspond to the appropriate position on the side wall of the daily fuel tank (the position of the galvanized pipe for installing the magnetic flap level gauge), and the level gauge flange is butt-welded to the galvanized pipe reserved on the daily fuel tank to complete the preliminary production of the daily fuel tank body. After the preliminary completion, the tank can be leak tested to ensure that there are no leaks in the tank and then the outside of the tank body can be painted. Finally, after purchasing the magnetic flap level gauge, the next step of installation can be carried out. The positioning welding tooling in this embodiment can avoid the problem of long production period of daily oil tanks caused by untimely procurement of magnetic flap level gauges. At the same time, it can also solve the problem that the level gauge is easily damaged when using a magnetic flap level gauge to position the flange welding on the daily oil tank.

[0037] In order to reduce production costs, the two flange fixing plates can be manufactured according to uniform specifications, that is, the first flange fixing plate 10 and the second flange fixing plate 20 have the same structure.

[0038] In some optional ways, in order to achieve the sliding connection between the first flange fixing plate 10 and the sliding rod 40, a corresponding sliding connection can be provided. The sliding connection can be a sliding tube and a top screw, or a sliding groove and a slider.

[0039] For example, Figure 1-Figure 2As shown, the sliding connection adopts a sliding tube and a top screw. Specifically, the positioning welding tool also includes a first sliding tube 501, a first top screw 502, a second sliding tube and a second top screw. The first sliding tube 501 is slidably mounted on the upper part of the sliding rod 40, and the first sliding tube 501 is connected to the first flange fixing plate 10; the first top screw 502 is used to limit and adjust the position of the first sliding tube 501 on the upper part of the sliding rod 40. Similarly, the second sliding tube is slidably mounted on the lower part of the sliding rod 40, and the second sliding tube is connected to the second flange fixing plate 20; the second top screw is used to limit and adjust the position of the second sliding tube on the lower part of the sliding rod 40. The combination of this sliding tube and the top screw can ensure the reliability of the sliding of the first flange fixing plate 10 and the second flange fixing plate 20 on the sliding rod 40, as well as the relative stability when the sliding rod 40 is in the upper limit state.

[0040] Exemplarily, the sliding connection uses a slide groove and a slider, that is, a slider is set on the corresponding flange fixing plate, and a slide groove is opened on the sliding rod 40 along the length direction of its rod body. Based on the sliding cooperation of the slider in the slide groove, the sliding connection of the corresponding flange fixing plate on the sliding rod 40 is realized.

[0041] In some optional ways, considering that a certain distance needs to be maintained between the sliding tube and the flange fixing plate to facilitate the operation of the staff, a connecting column 102 can be added between the sliding tube and the flange fixing plate. Figure 1-Figure 2 As shown, the first flange fixing plate 10 includes a circular plate 101 and a connecting post 102. One end of the connecting post 102 is connected to the circular plate 101, and the other end is connected to the first sliding tube 501. The circular plate 101 is provided with a plurality of flange connection holes 1011 extending through the plate body. The plurality of flange connection holes 1011 are evenly distributed around the circular plate 101 in a circle centered at a predetermined center.

[0042] It should be noted that the flange fixing plate may also be a square plate or other shapes, as long as there is enough space for the flange connection holes 1011 of the level gauge flange. Optionally, the number of the flange connection holes 1011 is 4n, where n is a positive integer.

[0043] In some optional embodiments, the connecting post 102 is detachably connected to the circular plate 101. A mounting hole for mounting the connecting post 102 is provided in the center of the circular plate 101. This embodiment facilitates the storage of the disassembled positioning welding tool after replacement.

[0044] In some optional ways, in order to achieve the docking of the magnetic flap level gauge, a flange connection hole 1011 adapted thereto needs to be provided on the level gauge flange. For example, Figure 2 As shown, multiple flange connection holes 1011 are evenly distributed around the circumference of the circular plate 101 with the center of the circular plate 101 as the center.

[0045] In some optional ways, considering that different models of magnetic flap level gauges are different and the flange models and sizes that are compatible with them are also different, the flange connection hole 1011 can be optimized to make it universal. For example, Figure 2 As shown, the plurality of flange connection holes 1011 are elongated holes, wherein each flange connection hole 1011 is opened along the radial direction of the circular plate 101 .

[0046] In some optional embodiments, to quickly adjust the positions of the first and second flange fixing plates 10 and 20, a scale can be provided and reference can be made to the specifications of a magnetic flap level gauge to improve adjustment efficiency. For example, a scale is provided on the slide rod 40 to locate the positions of the first and second flange fixing plates 10 and 20 on the slide rod 40.

[0047] In some optional ways, in order to fix the position of the positioning welding tool on the side wall of the daily fuel tank, a suction cup 301 can be used for adsorption. Figure 3 As shown, the suction assembly 30 includes a suction cup 301 and a connecting rod 302. The suction cup 301 is used to adhere to the side wall of the daily fuel tank. The connecting rod 302 is connected to the suction cup 301 at one end and to the middle of the sliding rod 40 at the other end. This method allows for rapid attachment and removal of the tack welding tool, is convenient for operators, and is cost-effective.

[0048] In some optional ways, considering that the distance between the slide rod 40 and the daily oil tank may not match, in order to facilitate the welding of the level gauge flange, the connection method between the connecting rod 302 and the slide rod 40 can be optimized. Figure 1 、 Figure 3 As shown, the connecting rod 302 is slidably connected to the sliding rod 40; wherein, the adsorption component 30 also includes a third top screw 303, and the third top screw 303 is used to limit and adjust the position of the connecting rod 302 in the middle of the sliding rod 40.

[0049] In this embodiment, the corresponding sliding tube is first welded to the connecting column 102 on the flange fixing plate, and then the sliding tube is put on the sliding rod 40. According to the specifications of the magnetic flap level gauge of the daily oil tank, the position of the corresponding flange fixing plate is adjusted to be the same as the flange position of the magnetic flap level gauge, fixed with a top screw, and the level gauge flange is fixed to the flange fixing plate with bolts, and the positioning welding tool is adsorbed on the wall of the daily oil tank with a suction cup 301. The connection position of the sliding rod 40 and the connecting rod 302 is adjusted, and then the level gauge flange is butt-welded to the galvanized pipe reserved on the daily oil tank. After completion, the oil tank is tested for leaks to ensure that there are no leaks in the oil tank. Paint the outside of the box and other operations are performed. Finally, the installation work is carried out after the magnetic flap level gauge is purchased.
