Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling for chemical equipment, in particular to an auxiliary welding tooling for a flange connection port of a double overflow composite plate tower. Background Art

[0002] Double overflow composite trays are a common chemical equipment, widely used in separation and purification processes in the petrochemical, pharmaceutical, and food industries. They are primarily used to effectively separate gases and liquids. Combining the advantages of double overflow trays with composite tray technology, this tower has unique functions and characteristics.

[0003] The structure of a double-overflow plate tower includes an outer shell equipped with an air inlet, air outlet, feed port, and discharge port. Inside the shell, a filter element, porous plates, and fans are installed. During the manufacturing process of the double-overflow plate tower shell, the manhole, air inlet, air outlet, feed port, and discharge port are all circular tubes with flanges. These circular tubes are generally connected to the shell using welding. To ensure the accurate connection between the plate tower and other equipment and pipelines, the welding angle of the circular tubes is required to ensure that the circular tubes appear vertical on the shell surface.

[0004] At present, manual welding is usually used to connect the above-mentioned circular tube structure with the outer shell. Before welding, a spirit level needs to be placed on the flange, and the flange needs to be adjusted to a horizontal position before welding. During the welding process, the circular tube may shake due to interference from environmental factors such as manual mis-touch and shaking of the lifting wire rope, causing deviations in the welding angle of the circular tube. Utility Model Content

[0005] The embodiment of the present application provides an auxiliary welding tool for the flange connection port of a double overflow composite plate tower, which is used to improve the accuracy of the welding angle of the circular tube structure on the outer shell surface.

[0006] The embodiment of the present application provides an auxiliary welding tool for the flange connection port of a double overflow composite plate tower, comprising:

[0007] A base, used for contacting with the outer shell of the double overflow composite plate tower;

[0008] A vertical pole connected to the base;

[0009] A crossbar, slidably arranged on the vertical rod;

[0010] a level, disposed on the crossbar;

[0011] A positioning member is used to position the cross bar on the vertical bar.

[0012] The beneficial effect of the above embodiment is that: the horizontal edge is adjusted to a horizontal position by a spirit level, and then the base is contacted with the shell, and the lower surface of the flange is contacted with the upper surface of the cross bar. The cross bar plays a positioning role, so that the flange is positioned in a horizontal position before welding, so that the flange is not easy to shake even after being disturbed by external factors, thereby ensuring the accuracy of the welding angle of the circular tube.

[0013] Based on the above embodiment, the embodiment of the present application can also be improved as follows:

[0014] In one embodiment of the present application, the lower end of the base is provided with an arc-shaped positioning groove that matches the outer shape of the housing. The beneficial effect of this step is that the positioning groove contacts the housing, thereby improving the stability of the base on the surface of the housing.

[0015] In one embodiment of the present application, the positioning member is threadedly connected to the crossbar, and a compression positioning structure is formed between the positioning member and the vertical pole. The beneficial effect of this step is that the threaded connection structure facilitates changing the position of the positioning member on the crossbar, thereby facilitating adjustment of the height of the crossbar on the vertical pole.

[0016] In one embodiment of the present application, a height scale is vertically arranged on the outer surface of the vertical pole. The beneficial effect of this step is that it is easy to determine the height position of the horizontal pole.

[0017] In one embodiment of the present application, a sliding connection assembly is further included to slide the two bases together in series. The beneficial effect of this step is that the sliding connection assembly connects the two bases and the level gauges thereon into a single structure, which is supported and positioned by two crossbars on both sides of the flange, thereby improving the stability of the flange positioning.

[0018] In one embodiment of the present application, the sliding connection assembly includes a guide sleeve connected to the base and a guide rod slidably inserted into the corresponding guide sleeve. The beneficial effect of this step is that the guide sleeve can prevent the base from being worn and facilitate the maintenance of the tooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] like Figure 1 、 2 As shown, an auxiliary welding tool for the flange connection port of a double overflow composite plate tower includes: a base 1, a vertical pole 2, a horizontal pole 3, a spirit level 4, and a positioning piece 5. The base 1 is used to contact the outer shell of the double overflow composite plate tower, the vertical pole 2 is connected to the base 1, the horizontal pole 3 is slidably set on the vertical pole 2, the spirit level 4 is set on the horizontal pole 3, and the positioning piece 5 positions the horizontal pole 3 on the vertical pole 2.

[0029] Among them, such as Figure 1 As shown, the lower end of the base 1 is equipped with an arc-shaped positioning groove 101 that matches the outer shell shape. Specifically, the base 1 comprises an upper plate and a lower plate connected by bolts. The upper plate is connected to the upright 2, and the lower plate has a positioning groove 101 on its lower surface. The positioning groove 101 contacts the outer shell, improving the stability of the base 1 on the outer shell surface.

[0030] Among them, such as Figure 1 、 2 As shown, the vertical rod 2 includes a left rod body and a right rod body, which are bolted to the upper end of the base 1 to form a bilaterally symmetrical structure. The crossbar 3 is provided with a sliding sleeve at each end, which is slidably mounted on the outer side of the corresponding left or right rod body. The ends of the crossbar 3 are slidably connected to the left and right rod bodies through the sliding sleeves, thereby improving the stability of the positioning of the crossbar 3.

[0031] Among them, such as Figure 1 As shown, the positioning member 5 is threadedly connected to the crossbar 3, and a compression and positioning structure is formed between the positioning member 5 and the upright 2. Specifically, the positioning member 5 is a butterfly bolt. A threaded hole is formed in the side of the sliding sleeve along the horizontal direction, connecting to the outer side of the upright 2. The positioning member 5 is threadedly connected to the threaded hole. This threaded connection structure facilitates the adjustment of the positioning member 5 on the crossbar 3, thereby facilitating the adjustment of the height of the crossbar 3 on the upright 2.

[0032] Among them, such as Figure 2 As shown, the level 4 is a purchased product, and a slot 301 is provided in the middle of the positioning rod corresponding to the level 4 , and the level 4 is inserted into the slot 301 in the horizontal direction.

[0034] When using this auxiliary welding tool, the base 1 is attached to the outer shell surface of the double overflow composite plate tower. The position of the base 1 is adjusted according to the level 4 until the crossbar 3 is in a horizontal position. The lower surface of the flange is then placed on the crossbar 3. At this time, the flange is positioned in the welding position, and the entire structure can be welded. During this process, the flange can find the assembly angle according to the position of the crossbar 3 and is positioned by the crossbar 3, improving the stability of the structural positioning during the welding process, thereby ensuring the accuracy of the welding angle of the entire structure.
