Description

Technical Field

[0001] The utility model relates to the technical field of chemical pipelines, in particular to a pipeline protective cover. Background Art

[0002] Chemical pipelines transport various chemical media, corrosive media, etc. During use, they are not only exposed to external physical impacts but also to corrosion from chemical liquids, which affects the service life of the pipelines and poses safety hazards to chemical production and workers. Therefore, safety shields are generally installed on the outer walls of chemical pipelines.

[0003] However, the existing pipe protective covers are used to protect the flanges at the pipe joints. However, at the pipe bend joints, some pipe protective covers are relatively long in design and are difficult to adapt to flanges of different widths or different relative positions. Workers are required to prepare pipe protective covers of corresponding lengths in advance, which increases the cost of chemical construction. At the same time, most pipe protective covers are connected by bolts and nuts, and some pipe protective covers are used in external environments. When exposed to outdoor environments eroded by rain, the bolts will rust. Over time, the connection parts of the pipe protective covers will become loose or fall off, thereby affecting the protective effect of the protective cover. Utility Model Content

One side of the sealing sleeve 5 is installed with the surface of the first protective shell 1. The sealing performance of the first protective shell 1 is increased. An adjustment mechanism 6 is provided on one side of the rotating rod 4. With the cooperation of the hand-turning rod 3 and the rotating rod 4, the adjustment mechanism 6 can be operated. The adjustment mechanism 6 and the second protective shell 2 are used in conjunction with each other. Under the action of the adjustment mechanism 6, the second protective shell 2 can be moved in the inner cavity of the first protective shell 1, so that the second protective shell 2 can be adjusted according to the width of different flanges, thereby increasing the practicality of the pipeline protective cover. The surface of the first protective shell 1 is fixedly connected with a fixing block 8, and the inner cavity of the fixing block 8 is threadedly connected with a bolt 9. With the cooperation of the fixing block 8 and the bolt 9, the upper and lower second protective shells 2 can be moved. A protective shell 1 is connected to each other, and the top of the fixed block 8 is movably connected to a protective shell 10. The protective shell 10 can protect the bolt 9, effectively preventing the bolt 9 from rusting due to rain, thereby increasing the service life of the bolt 9. One side of the protective shell 10 is fixedly connected to a connecting block 11, and the top of the fixed block 8 is bolted to a fixed shell 12. The top of the connecting block 11 is fixedly connected to a compression spring 13, and the top of the compression spring 13 is fixedly connected to the inner cavity of the fixed shell 12. Under the cooperation of the protective shell 10 and the connecting block 11, the compression spring 13 can be compressed inside the fixed shell 12, so that the protective shell 10 can be moved to the inner cavity of the fixed shell 12. The fixing shell 12 is moved upward, and a limiting mechanism 15 is provided on one side of the fixing shell 12. Under the action of the limiting mechanism 15, the protective shell 10 can be effectively prevented from being affected when the staff installs the bolts 9, which facilitates the staff to install the bolts 9. The inner cavity of the fixing shell 12 is fixedly connected with a guide rod 14, and the guide rod 14 is located at the center of the compression spring 13. The surface of the guide rod 14 is slidably connected to the inner cavity of the connecting block 11. Under the action of the guide rod 14, the compression spring 13 can be effectively prevented from positionally shifting during operation, thereby increasing the stability of the compression spring 13 and thus improving the stability of the pipe protective cover.

[0023] The adjusting mechanism 6 includes a threaded rod 61, one end of the threaded rod 61 is fixedly connected to one end of the rotating rod 4, and the other end of the threaded rod 61 is rotatably connected to the inner cavity of the first protective shell 1.

The top of the sleeve 62 is fixedly connected to a guide block 7, and the surface of the guide block 7 is slidably connected to the inner cavity of the first protective shell 1. Under the action of the guide block 7, the sleeve 62 can be effectively prevented from rotating during movement, thereby increasing the stability of the adjusting mechanism 6 and thus improving the stability of the pipeline protective cover.

[0024] The limiting mechanism 15 includes a mounting block 151, one side of the mounting block 151 is bolted to the surface of the connecting block 11, and a supporting block 152 is bolted to the surface of the fixed shell 12. The inner cavity of the supporting block 152 is slidably connected to the limiting rod 153, and the surface of the limiting rod 153 is slidably connected to the inner cavity of the mounting block 151. With the cooperation of the connecting block 11 and the compression spring 13, the mounting block 151 can be moved to one side of the support block 152, and the limiting rod 153 can pass through the interior of the mounting block 151 and move to the interior of the support block 152, effectively preventing the compression spring 13 from rebounding and driving the protective shell 10 back to its original position, thereby facilitating the staff to install the bolt 9.

[0025] Working principle: When the staff needs to adjust the width of the pipe protective cover according to flanges of different widths, the staff rotates the threaded rod 61 through the rotating rod 4 through the hand-turning rod 3, and the threaded rod 61 moves the connecting rod 63 through the sleeve 62. The connecting rod 63 drives the second protective shell 2 to move in the inner cavity of the first protective shell 1, so that the second protective shell 2 and the first protective shell 1 can protect the flange of the pipe protective cover. When the staff needs to connect the upper and lower first protective shells 1, with the cooperation of the protective shell 10 and the connecting block 11, the compression spring 13 can be compressed in the inner cavity of the fixed shell 12, so that the protective shell 10 Move upward away from the fixing block 8, and at the same time, the connecting block 11 drives the mounting block 151 to move to a position corresponding to the support block 152. The staff passes the limit rod 153 through the inner cavity of the mounting block 151 and moves the limit rod 153 to the inner cavity of the support block 152 to prevent the compression spring 13 from rebounding and driving the protective shell 10 to move downward. Then the staff connects and installs the upper and lower first protective shells 1 through the bolts 9, and then the staff moves the limit rod 153 out of the interior of the mounting block 151 and the support block 152. Under the action of the rebound of the compression spring 13, the protective shell 10 can return to its original position to protect the bolts 9.
