[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, this utility model provides a technical solution: a special plastic steel braided spiral composite pipe, including a composite pipe body 1. A positioning frame 2 is fixedly connected to the outer surface of the composite pipe body 1. A fixing bolt 3 is threadedly connected to the inner wall of the positioning frame 2. A fixing flange 4 is threadedly connected to one end of the fixing bolt 3. A fixing pipe 5 is snapped into the inner wall of the fixing flange 4. An installation bolt 6 is threadedly connected to the inner wall of the fixing pipe 5. A connecting flange 7 is snapped into one end of the fixing flange 4. A circular slot is opened at one end of the composite pipe body 1. A connecting pipe 8 is snapped into the inner wall of the circular slot. A rubber sleeve 9 is fixedly connected to one end of the connecting pipe 8. An arc-shaped groove is opened on the inner wall of the fixing flange 4. A connecting pipe 8 is fixedly connected to the inner wall of the arc-shaped groove. A sealing sleeve 11 is attached, and the inner edge of the fixed flange 4 is engaged with the outer surface of the composite pipe body 1 near the positioning frame 2. The outer surface of the rubber sleeve 9 is engaged with the inner wall of the composite pipe body 1. Through the arrangement of the composite pipe body 1, positioning frame 2, fixing bolts 3, fixing flange 4, fixing pipe 5, mounting bolts 6, connecting flange 7, connecting pipe 8, and rubber sleeve 9, when the device is damaged, the operator can rotate the fixing pipe 5 and mounting bolts 6 on the fixing flange 4 and connecting flange 7 to separate the fixing pipe 5 from the mounting bolts 6, and separate the fixing flange 4 and connecting flange 7. The operator can then observe the connection between the fixing flange 4 and the connecting flange. Regarding the situation on flange 7, according to existing flange installation regulations, if the flange surface has a dent exceeding 0.2mm, both the fixed flange 4 and the connecting flange 7 need to be replaced. Workers can rotate the fixing bolt 3 inside the positioning bracket 2 on the outer surface of the composite pipe body 1, removing one end of the fixing bolt 3 from the damaged flange, separating the composite pipe body 1 from the damaged flange, and replacing it. Insert the new flange along the composite pipe body 1 until the positioning bracket 2 abuts against the flange. Workers then screw the fixing bolt 3 into the corresponding threaded grooves on the positioning bracket 2 and the replaced flange, reconnect the maintained composite pipe body 1, and connect the connecting pipe 8 on the composite pipe body 1. The rubber sleeve 9 on one end of the connecting pipe 8 can improve the sealing performance between the two composite pipe bodies 1. The fixing pipe 5 is inserted into the corresponding circular slots of the fixing flange 4 and the connecting flange 7. The mounting bolt 6 is screwed into the fixing pipe 5, so that one end of the mounting bolt 6 and one end of the fixing pipe 5 abut against the two sides of the fixing flange 4 and the connecting flange 7 respectively. This arrangement makes it convenient for the staff to maintain the device. The sealing sleeve 11 on the inner wall of the fixing flange 4 can improve the sealing effect between the fixing flange 4 and the composite pipe body 1. The fixing flange 4 will abut against the positioning frame 2. The rubber sleeve 9 can improve the sealing effect between the two composite pipe bodies 1.

[0020] A circular slot is provided on the back edge of the connecting flange 7. One end of the inner wall of the circular slot is engaged with one end of the mounting bolt 6. With the connection flange 7 and the mounting bolt 6, one end of the mounting bolt 6 will abut against the connecting flange 7 during use.

[0021] The front sides of the fixed flange 4 are provided with arc-shaped grooves, and the inner wall of the arc-shaped grooves is fixedly connected with the mating plate 10. With the setting of the fixed flange 4 and the mating plate 10, the mating plate 10 is fixed on both sides of the front of the fixed flange 4 during use.

[0022] The front sides of the connecting flange 7 are provided with mounting grooves. The inner wall of the mounting grooves is engaged with one end of the mating plate 10. With the connection flange 7 and the mating plate 10, the mounting grooves on the front sides of the connecting flange 7 will mate with the mating plate 10 on the fixed flange 4 during use.

[0023] In this invention, the working steps of the device are as follows:

[0024] First step: When the device is damaged, the operator can rotate the fixed pipe 5 and mounting bolt 6 on the fixed flange 4 and connecting flange 7 to separate the fixed pipe 5 from the mounting bolt 6 and the fixed flange 4 and connecting flange 7. The operator can observe the condition of the fixed flange 4 and connecting flange 7. According to the existing flange installation regulations, if the flange surface has a dent of more than 0.2mm, the fixed flange 4 and connecting flange 7 need to be replaced. The operator can rotate the fixing bolt 3 in the positioning bracket 2 on the outer surface of the composite pipe body 1 to remove one end of the fixing bolt 3 from the damaged flange, so that the composite pipe body 1 is separated from the damaged flange and replaced. Insert the new flange along the composite pipe body 1 until the positioning bracket 2 abuts against the flange. The operator screws the fixing bolt 3 into the corresponding thread groove on the positioning bracket 2 and the replaced flange.

[0025] The second step is to reconnect the maintained composite pipe body 1. Insert the connecting pipe 8 on the composite pipe body 1 into the composite pipe body 1 at the installation location. The rubber sleeve 9 on one end of the connecting pipe 8 can improve the connection sealing between the two composite pipe bodies 1. Insert the fixing pipe 5 into the corresponding circular slots of the fixing flange 4 and the connecting flange 7. Screw the mounting bolt 6 into the fixing pipe 5, so that one end of the mounting bolt 6 and one end of the fixing pipe 5 abut against the two sides of the fixing flange 4 and the connecting flange 7 respectively.
