Description

Technical Field

[0001] The utility model belongs to the technical field of chemical engineering, and in particular relates to a pipeline splash-proof device for chemical safety. Background Art

[0002] In chemical production, chemical raw materials are transported by connecting pipelines and flanges. Since chemical raw materials are highly corrosive, the connections between pipelines and flanges are susceptible to chemical corrosion and aging, resulting in leakage. In serious cases, there is a possibility of liquid spraying or leakage in the pipeline that may injure people, causing accidents and pollution.

[0003] During the inspection and maintenance of the pipeline, it is necessary to check the tightness of the bolts. During the inspection, some bolts are loose, which may cause the raw materials in the pipeline to spray out during the twisting test, which may easily cause harm to the maintenance personnel. Utility Model Content

[0006] A moving wheel is fixedly connected to the side of the connecting plate, and the moving wheel overlaps the outer surface of the pipe. The moving wheel is hinged to one end of the telescopic rod through a pin shaft, and the other end of the telescopic rod is fixedly connected to the side of the second fixed plate. The upper surface of the second fixed plate is fixedly connected to the inner surface of the protective tube through a hinge, and a spring is provided on the surface of the telescopic rod.

[0007] As a further solution of the utility model: the end of the connecting plate away from the first fixing plate is arranged obliquely.

[0008] As a further solution of the utility model: there are eight adjusting components in total, and four are divided into one group, and two groups of adjusting components are arranged at the front and rear positions of the protective tube, and one group of adjusting components is equidistantly arranged on the outside of the pipeline.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The chemical safety pipeline splash prevention device, through the arrangement of structures such as pipelines, protective tubes, fixed plates, connecting plates, moving wheels and springs, can move the protective tube to the maintenance position during the pipeline maintenance process. When the staff performs detection operations, the protective effect of the protective tube can prevent the splashing of liquid in the pipeline from causing harm to the staff.

[0016] Example

[0017] See also Figure 1-2 The utility model provides the following technical solutions: a chemical safety pipeline 1 splash prevention device, comprising a pipeline 1, the outer side of the pipeline 1 is sleeved with a protective tube 2, the inner surface of the protective tube 2 is provided with an adjustment component, the adjustment component comprises a first fixing plate 3 fixedly connected to the inner surface of the protective tube 2, the side of the first fixing plate 3 is hinged to the side of the connecting plate 4 by a hinge (not shown in the figure), and when the hinge is provided, the adjustment component can be easily moved, thereby facilitating the movement of the protective tube 2;

[0018] A moving wheel 5 is fixedly connected to the side of the connecting plate 4, and the moving wheel 5 overlaps the outer surface of the pipeline 1, so that the protective tube 2 can be easily moved when the moving wheel 5 rolls. The moving wheel 5 is hinged to one end of the telescopic rod 6 through a pin (not shown in the figure), and the hinged setting facilitates the rotation of the connecting plate 4. The other end of the telescopic rod 6 is fixedly connected to the side of the second fixed plate 7, and the upper surface of the second fixed plate 7 is fixedly connected to the inner surface of the protective tube 2 through a hinge. The surface of the telescopic rod 6 is sleeved with a spring 8, and the restoring force of the spring 8 can make the moving wheel 5 approach the position of the pipeline 1.

[0019] Specifically, the end of the connecting plate 4 away from the first fixing plate 3 is arranged in an inclined manner, and the inclined arrangement facilitates the contact between the connecting plate 4 and the flange to adjust the position of the moving wheel 5 .

[0020] Specifically, there are eight adjustment components in total, and four are divided into a group, and two groups of adjustment components are arranged at the front and rear positions of the protective tube 2, and one group of adjustment components is equidistantly arranged on the outside of the pipeline 1.

[0021] The working principle of the utility model is:

[0022] During use, the staff can push the protective cylinder 2, and the protective cylinder 2 can be moved when the moving wheel 5 in the adjustment component is in contact with the pipeline 1. When the connecting plate 4 is in contact with the flange position of the pipeline 1, the protective cylinder 2 can continue to be pushed. At this time, the connecting plate 4 rotates through the action of the hinge and the pin shaft, so that the telescopic rod 6 and the spring 8 are compressed, thereby ensuring that the protective cylinder 2 can be further moved. In the process of the moving wheel 5 gradually separating from the flange, the moving wheel 5 gradually approaches the pipeline 1 through the restoring force of the spring 8 until the moving wheel 5 contacts the pipeline 1 again.
