Description

Technical Field

[0001] This utility model relates to the field of pipeline renovation technology, specifically to a rust-proof and corrosion-preserving brush coating device for pipeline renovation. Background Technology

[0002] Urban underground pipelines refer to various pipelines and their ancillary facilities laid underground within a city. They are important infrastructures that ensure the normal operation of the city and are known as the city's "lifeline." When modifying and maintaining pipelines for rust prevention and corrosion protection, a brush coating device is required. This device is specially designed for rust prevention and maintenance of the inner or outer walls of pipelines. This device combines multiple technologies such as spraying or brushing to ensure that the pipeline surface can be uniformly and efficiently coated with anti-rust materials, thereby extending the service life of the pipeline and improving its operating efficiency.

[0003] Currently used brush coating devices do not have the function of protecting the carrier roller. Usually, a shielding material is needed to shield the carrier roller and the pipeline before spraying. However, the shielding material is easy to shake, and the anti-rust paint can easily splash onto the carrier roller. This not only affects the surface quality of the carrier roller, but may also have adverse effects on its subsequent use, such as increasing frictional resistance and reducing service life. Utility Model Content

[0004] The purpose of this invention is to provide a rust-prevention and corrosion-preserving brushing device for pipeline renovation, so as to solve the problems mentioned in the background art.

[0020] 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.

[0021] Please see Figure 1-4 As shown, a rust-preventive coating device for pipeline renovation includes a main body 1. Insert brackets 2 are bolted to both sides of the main body 1. A baffle 3 is provided on one side of each insert bracket 2, which can be inserted into the insert bracket 2 from the top. The baffles 3 on both sides shield the bearing roller of the main body 1 and the sides of the pipeline, preventing rust-preventive paint from adhering to the surface of the bearing roller. A positioning groove 4 is provided on one side of the baffle 3. A fixing bracket 5 is bolted to one side of the insert bracket 2. A positioning mechanism 6 is provided on one side of the fixing bracket 5, preventing parts inside the positioning mechanism 6 from falling out. The positioning mechanism 6 works in conjunction with the positioning groove 4. When the internal parts of the positioning mechanism 6 enter the interior of the positioning groove 4, it can prevent the baffle 3 from easily detaching from the interior of the insert 2. Support frames 7 are bolted to both sides of the surface of the brushing device body 1. A mounting plate 8 is bolted to the top of the support frame 7. The mounting plate 8 is located on the back of the baffle 3. A cleaning mechanism 9 is provided inside the mounting plate 8. The cleaning mechanism 9 works in conjunction with the baffle 3. When the cleaning mechanism 9 is running, it can clean the paint layer attached to the surface of the baffle 3. Collection grooves 10 are provided on both sides of the surface of the brushing device body 1. The cleaned paint layer can be collected under the action of the collection grooves 10.

[0022] The positioning mechanism 6 includes a pull rod 61. One side of the surface of the pull rod 61 is slidably connected to the inner wall of one side of the fixed frame 5. A positioning plate 62 is bolted to one end of the surface of the pull rod 61. When the pull rod 61 moves, the positioning plate 62 can move. When the positioning plate 62 moves to the appropriate position, it releases the obstruction on one side of the inside of the insert 2. Under this action, the baffle 3 can be inserted into the inside of the insert 2. Two compression springs 63 are fixedly connected to the surface of the positioning plate 62 and are evenly distributed on both sides of the surface of the positioning plate 62. The other end of the surface of the compression spring 63 is connected to one side of the surface of the fixed frame 5. The side is fixedly connected. When the positioning plate 62 moves, the compression springs 63 on both sides can be compressed. Limiting rods 64 are bolted to both sides of the surface of the positioning plate 62. One side of the surface of the limiting rod 64 is slidably connected to the inner wall of one side of the fixed frame 5. When the positioning plate 62 moves, the limiting rod 64 can move. Under the action of the limiting rods 64 on both sides, the positioning plate 62 can move more stably. When the baffle 3 is inserted into the insert 2, the positioning plate 62 can return to its original position and enter the interior of the positioning groove 4 under the action of the compression springs 63 on both sides. Under this action, the baffle 3 can be prevented from easily moving out of the interior of the insert 2.

[0023] The cleaning mechanism 9 includes a screw rod 91. One end of the screw rod 91 is rotatably connected to one side of the mounting plate 8. A reciprocating threaded rod 92 is bolted to one end of the screw rod 91. The other end of the reciprocating threaded rod 92 is rotatably connected to one side of the inner wall of the mounting plate 8. When the screw rod 91 rotates, the reciprocating threaded rod 92 rotates. A transmission seat 93 is threadedly connected to the surface of the reciprocating threaded rod 92. The surface of the transmission seat 93 is slidably connected to the inner wall of the mounting plate 8. When the reciprocating threaded rod 92 rotates, the transmission seat 93 reciprocates. The shape of 3 is T-shaped and the inner wall of the mounting plate 8 is also T-shaped. This design makes the movement of the transmission seat 93 more stable. A connecting frame 94 is bolted to one side of the surface of the transmission seat 93. When the transmission seat 93 moves, the connecting frame 94 can move. The connecting frame 94 is U-shaped. A scraper 95 is bolted to one side of the surface of the connecting frame 94. When the connecting frame 94 moves, the scraper 95 can move. When the scraper 95 moves, the paint layer on the surface of the baffle 3 can be cleaned. The length of the scraper 95 is equal to the distance from the top of the insert 2 to the top of the baffle 3.

[0024] Working principle: When spraying is required on the pipe, pull rods 61 on both sides are pulled. When pull rods 61 move, positioning plate 62 moves. Then, positioning plate 62 moves, compressing compression springs 63 on both sides. At the same time, when positioning plate 62 moves, limiting rods 64 on both sides move. When positioning plate 62 moves to the appropriate position, it can release the obstruction to the inside of insert 2. Next, baffle 3 is inserted into the inside of insert 2. Then, the tension on pull rods 61 is released. Under the action of compression springs 63 on both sides, positioning plate 62 can quickly return to its original position. Under this action, positioning plate 62 can enter the inside of positioning groove 4. It can prevent the baffle 3 from easily detaching from the inside of the insert 2. When the main body 1 of the brushing device sprays the pipe, the baffle 3 can prevent the anti-rust paint from adhering to the surface of the bearing roller. The two sides of the pipe that cannot be sprayed can be brushed manually later. When the paint layer on the surface of the baffle 3 is too thick, rotate the screw rod 91. When the screw rod 91 rotates, it can cause the reciprocating threaded rod 92 to rotate. Then, the reciprocating threaded rod 92 can cause the transmission seat 93 to move back and forth. Next, the movement of the transmission seat 93 can drive the connecting frame 94 to move. When the connecting frame 94 moves, it can drive the scraper 95 to move. Then, the movement of the scraper 95 can clean the paint layer on the surface of the baffle 3.
