Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The following working principles, detailed connecting means thereof, and the following main descriptions of the working principles and processes are well known in the art, and will be referred to by those skilled in the art for the specific connection and operation sequence of the components in this application.

The first embodiment is as follows: as can be seen from fig. 1-3, a mining plastic-coated pipe flange end protection device comprises two pipe bodies 1, wherein flange plates 2 are fixedly connected to the inner sides of the two pipe bodies 1, the two flange plates 2 are attached to each other, cylinders 3 are fixedly connected to the outer walls of the two pipe bodies 1, sliders 15 are slidably clamped into grooves on the upper side and the lower side of the outer walls of the two cylinders 3, two protective covers 4 are fixedly connected to the outer sides of the sliders 15, the inner sides of the two protective covers 4 are attached to each other, bolts 6 are respectively in clearance fit with through holes on the tops of the two protective covers 4, bent rods 7 are respectively in clearance fit with through holes on one sides of the bolts 6, one side of the outer wall of each bent rod 7 is in clearance fit with the through hole on the top of the right protective cover 4, a bottom plate 8 is fixedly connected to one end of each bent rod 7, a spring 9 is in clearance fit with the outer wall of each bent rod 7, and two ends of the spring 9 are respectively fixedly connected to the upper sides of the right protective covers 4 and the upper sides of the bottom plate 8;

in the specific implementation process, it is worth particularly pointing out that the problem that the existing device is inconvenient to connect the protective cover 4 when working is solved through the cooperation among the bent rod 7, the bolt 6 and the spring 9, the installation time is prolonged in practical use, and the working efficiency is reduced;

specifically, when using this mining plastic-coated pipe flange end protection device, the user is when connecting two safety covers 4, at first promotes two safety covers 4, guarantees that two safety covers 4 support tightly together, and the knee 7 of pulling up then inserts bolt 6, and behind the bolt 6 motion tip, the user loosens knee 7, drives the knee 7 joint and fixes in the recess of bolt 6 under the elastic deformation of spring 9, and whole process is simple swift.

Example two: as can be seen from fig. 1, 2 and 4, the contact position of the two protective covers 4 is provided with a first sealing ring 10, the inner sides of the two protective covers 4 are fixedly connected with ring cylinders 14, the inner sides of the two ring cylinders 14 are respectively abutted against the outer sides of the two flange plates 2, and the inner sides of the two ring cylinders 14 are provided with second sealing rings 5;

in the specific implementation process, it is worth pointing out that the first sealing ring 10 and the second sealing ring 5 ensure the sealing at the interface of the flange 2;

furthermore, the top of the left protective cover 4 is communicated with a glass tube 11, and the bottom of the inner wall of the glass tube 11 is in clearance fit with a round ball 12;

in the specific implementation process, it is worth noting that the spherical ball 12 can change with the air pressure inside the two protective covers 4, so as to remind the user whether leakage occurs;

furthermore, scales 13 are processed on the front surface of the glass tube 11, and lubricating oil is coated on the inner wall of the glass tube 11;

in the specific implementation process, it is worth pointing out that the scale 13 can facilitate the user to observe the leakage amount, and the lubricating oil can reduce friction and ensure the sealing between the round ball 12 and the glass tube 11;

specifically, on the basis of the first embodiment, the first sealing ring 10 and the second sealing ring 5 are installed at the contact position of the protective cover 4, so that sealing is ensured, if the flange 2 leaks, the round ball 12 is jacked up due to the increase of the internal air pressure, and a user can observe the position of the round ball 12 to judge whether the flange leaks or not and timely process the leakage.
