Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, and particularly relates to a fixing tooling for processing a pipeline air collecting hood. Background Technique

[0002] When collecting and collecting dust in a pipeline, a conical pipeline air collecting hood needs to be installed at the air inlet of the pipeline. Flanges are installed at the bottom of the narrow end and the inner side surface of the wide end of the conical pipeline air collecting hood to facilitate connection with the air inlet pipeline, so that the collected dust can smoothly enter the pipeline for collection.

[0003] In the prior art, when installing the flange on the inner side surface of the wide end, the flange needs to be initially clamped on the inner side wall of the wide end and then welded. Since the conical air collecting hood is wider at the top and narrower at the bottom, during the process of clamping the flange, the conical air collecting hood shakes and is unstable, resulting in a reduction in the clamping and installation efficiency of the flange, and thus a low production efficiency of the overall environmental protection equipment. Content of the Utility Model

[0004] In view of the problems raised in the background technique, the utility model researches and designs a fixing tooling for processing a pipeline air collecting hood, and its purpose is to provide a fixing tooling for processing a pipeline air collecting hood with good stability and high flange installation efficiency during flange installation.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fixing tooling for processing a pipeline air collecting hood, including support legs, a support table, and limit blocks. The support table is installed on the top of the support legs, and the limit blocks are installed on the top of the outer side ends of the support table.

[0007] Preferably, the support table is four support rods in the same horizontal plane, and two adjacent support rods are perpendicular to each other.

[0008] Preferably, the number of the support legs is four.

[0009] Preferably, a limit piece is arranged on the inner side surface of the top of the limit block, so that the whole limit block is in an inverted L shape.

[0010] Preferably, the number of the limit pieces is four. When the inner side surfaces of the four limit pieces are connected to each other, the inner side surfaces of the four limit pieces form a circle with the intersection point of the four support rods as the center.

[0011] The beneficial effects of the utility model: The structure of the utility model is reasonable and novel. The arranged limit blocks and support table enable the conical air collecting hood to be stably placed, ensuring that the conical air collecting hood does not shake or move around when the flange is embedded in the inner side wall of the wide end of the conical air collecting hood, improving the processing efficiency of the conical air collecting hood, and having high practical value. Description of the Drawings

[0012] Figure 1 This is a schematic structural view of the present utility model.

[0013] Wherein: 1. Support leg, 2. Limit block, 3. Support rod, 4. Limit piece. Specific embodiments

[0014] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0015] As Figure 1 shown, a fixing tool for processing a pipeline gas collecting hood includes a support leg 1, a support table, and a limit block 2. The support table is installed on the top of the support leg 1, and the limit block 2 is installed on the top of the outer side end of the support table.

[0016] In this embodiment, the support table is four support rods 3 on the same horizontal plane, and two adjacent support rods 3 are perpendicular to each other.

[0017] In this embodiment, there are four support legs 1.

[0018] In this embodiment, a limit piece 4 is arranged on the inner side surface of the top of the limit block 2, so that the limit block 2 as a whole is in an inverted L shape.

[0019] In this embodiment, there are four limit pieces 4. When the inner side surfaces of the four limit pieces 4 are connected to each other, the inner side surfaces of the four limit pieces form a circle with the intersection point of the four support rods 3 as the center.

[0020] Specific usage process: In the actual usage process, when the present utility model is only applicable to the processing of a certain specific model of conical gas collecting hood, first install a flange at the narrow end of the conical gas collecting hood, then place the conical gas collecting hood with the wide end facing up and the narrow end facing down on the support rod 3. At the same time, the inner side surfaces of the four limit pieces 4 are closely attached to the outer side surface of the lower part of the conical gas collecting hood, and the flange is initially clamped on the inner side wall of the wide end and then the welding work between the flange and the inner side wall of the wide end is carried out. During the embedding process of the flange, the four limit pieces 4 and the support rod 3 will stabilize the conical gas collecting hood and prevent it from shaking or moving around randomly.

[0021] During actual use, a scale (not marked in the figure) can also be provided on the support rod 3, and the four support rods 3 can be set as telescopic support rods 3 (that is, according to the narrow port diameter of the conical air hood, and then according to the scale on the support rod 3, the support rod 3 is extended or retracted to an appropriate length. Then, the wide end of the conical air hood is placed upward, and the narrow end is placed downward on the support rod 3. At the same time, the inner sides of the four limit pieces 4 are closely attached to the outer side of the lower part of the conical air hood), so that the utility model can be applied to the embedded installation of the inner side flange of the wide end of the conical air hood with different diameters. Each of the above telescopic support rods 3 can be set as two rods sleeved with each other. After one rod (not marked in the figure) is sleeved inside another hollow rod (not marked in the figure), it is fixed by bolts (not marked in the figure).

[0022] The limit block 2 and the support platform provided in the utility model enable the conical air hood to be stably placed, ensuring that the conical air hood will not shake or move around when the flange is embedded on the inner side wall of the wide end of the conical air hood, improving the processing efficiency of the conical air hood, and thus improving the overall production efficiency of the fan, which has high practical value.

[0023] In summary, the utility model achieves the expected effect.

[0024] The above is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Although the utility model has been disclosed above with a preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments with equivalent changes within the scope of the technical solution of the utility model. However, as long as it does not depart from the content of the technical solution of the utility model, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
