Description

Technical Field

[0001] This utility model relates to the technical field of pipe lining equipment, specifically to a coating tool for pipe lining. Background Technology

[0002] During manufacturing, transportation, or service, pipe surfaces can develop oxide scale, rust, and welding residue (such as yellow, blue, and black weld spots). Acid pastes (such as pickling and passivation pastes) containing nitric acid, hydrofluoric acid, and other components can quickly dissolve these impurities, giving the metal surface a uniform silvery-white appearance and providing a clean base for subsequent lining construction.

[0003] In related technologies, in order to line the manufactured pipes, acid paste is applied to the inner wall of the pipes. Traditionally, acid paste is applied to pipes manually by brushing, roller brushing, spraying with a spray gun, or automatically by industrial robots.

[0004] However, when lining longer pipes, such as 12m long pipes, with acid paste, manual operation is inconvenient due to the length of the pipe, and industrial robot spraying is costly. Furthermore, the above two methods are not convenient for uniformly coating the inner wall of the pipe, resulting in a weak lining effect. To solve the above problems, a coating tool for pipe lining is proposed. Utility Model Content

[0005] In view of this, the present invention provides a coating fixture for pipe lining. The present invention uses a positioning component combined with a wire to fix two sponge discs together, forming a cylinder that fits the dimensions of the inner wall of the pipe. The edges of the sponge discs are in contact with the inner wall of the pipe. A rotating device drives the wire to rotate, which in turn drives the positioning component and the sponge discs to rotate. A sliding device moves the rotating device, thereby pulling the sponge discs along the axial direction of the pipe. This allows the rotating sponge discs to carry the acid paste liquid and uniformly coat the inner wall of the pipe, thereby reducing the cost of pipe lining and improving production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a coating fixture for pipe lining, including a pair of sponge discs, a connecting piece between the sponge discs, a positioning disc on the side of each sponge disc away from the connecting piece, an opening in the center of each sponge disc, the opening penetrating the connecting piece and all the positioning discs, a wire inside the opening, a positioning component on the side of each positioning disc away from the connecting piece, each positioning component being hinged to the wire, a linkage ring on the end of the wire away from the connecting piece, a rotating device rotatably mounted on the end of the linkage ring away from the connecting piece, and a sliding device movably mounted at the bottom of the rotating device.

[0007] Each positioning component includes a positioning rod that fits into the opening. The positioning rod is used to fix the positioning plate and also to prevent the positioning plate and sponge plate from falling off. The middle of each positioning rod is connected to a wire. A positioning buckle is fixedly installed on both sides of the middle of each positioning rod. The positioning buckle is used to reinforce the connection between the positioning rod and the positioning plate, so that the two positioning components form a clamping part to clamp and fix the pair of sponge plates in the middle.

[0008] The positioning buckles are arc-shaped, and both ends of each positioning buckle are hinged together after passing through the positioning plate on the same side.

[0009] A linkage rod is provided at the end of the linkage ring away from the wire. The linkage rod is used to connect the linkage ring to the connecting shaft. The linkage ring is used to connect the wire to the linkage rod. The rotating device includes a motor bracket for mounting the drive motor. The motor bracket is an L-shaped plate. The drive motor is provided on the bearing surface at the rear of the motor bracket. The drive motor is used to drive the connecting shaft to rotate, thereby driving the linkage plate fixed to the connecting shaft to rotate, and thus causing the wire and the sponge disc connected to its front end to rotate. A coupling is embedded in the motor bracket. The coupling is used to rotatably connect the drive motor and the connecting shaft. One end of the coupling is rotatably connected to the output shaft of the drive motor. The other end of the coupling is rotatably provided with a connecting shaft. The connecting shaft is used to connect the linkage rod to the drive motor. The connecting shaft is connected to the linkage rod.

[0010] The drive motor has a motor base at its bottom, which is used to mount the drive motor and connect it to the motor bracket. The motor base and the motor bracket are fixed together by bolts.

[0011] The sliding device includes a slide rail for moving a slider. A slider is slidably mounted at the front end of the slide rail, connecting a support block to the slide rail and, consequently, a motor bracket connected to the support block. Thus, when the slider moves, the motor bracket and the drive motor move synchronously. A support block is mounted at the top of the slider, connecting the motor bracket to the slider. The top of the support block is connected to the base plate at the bottom of the motor bracket. An electric push rod is retractably mounted on the slide rail, pushing the motor bracket to move along the track of the slide rail. The drive end of the electric push rod is fixed to the end of the slide rail away from the wire, and the telescopic end of the electric push rod is connected to the rear of the motor bracket.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. Two sponge discs are fixed together by a positioning component and wire to form a cylinder that fits the inner wall of the pipe. The edges of the sponge discs are in contact with the inner wall of the pipe. A rotating device drives the wire to rotate, which in turn drives the positioning component and the sponge discs to rotate. A sliding device moves the rotating device, which pulls the sponge discs along the axial direction of the pipe. This allows the rotating sponge discs to carry the acid paste liquid and evenly coat the inner wall of the pipe, thereby reducing the cost of pipe lining and improving production efficiency.

[0014] 2. The linkage rod is used to connect the linkage ring to the connecting shaft. The linkage ring is used to connect the wire to the linkage rod. The motor bracket is used to install the drive motor, so that the linkage ring connected to the linkage rod drives the wire to rotate, which in turn drives the positioning plate and the sponge plate to rotate inside the pipe. The drive motor is used to drive the connecting shaft and the linkage rod to rotate, which in turn drives the linkage plate fixed to the connecting shaft to rotate, which in turn drives the wire and the sponge plate connected to its front end to rotate.

[0015] 3. The positioning rod is used to fix the positioning plate and prevent the positioning plate and sponge plate from falling off. The positioning buckle is used to reinforce the connection between the positioning rod and the positioning plate, so that the two positioning components form a clamping part to clamp and fix the pair of sponge plates in the middle.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] like Figures 1-4 As shown: This embodiment provides a coating fixture for pipe lining, including a pair of sponge discs 100. Each sponge disc 100 is disc-shaped and custom-made to the inner wall dimensions of the pipe to be coated. The sponge discs 100 are relatively inexpensive and can be cut to size. The size of each sponge disc 100 is larger than that of a positioning disc 102. A connecting piece 101 is provided between the sponge discs 100. The connecting piece 101 can be made of thin plastic. Each sponge disc 100 has a positioning disc 102 on the side away from the connecting piece 101. Both the connecting piece 101 and the positioning disc 102 are made of plastic and can be cut from factory waste. The size of the connecting piece 101 is smaller than that of the positioning disc 102. The positioning discs 102 are made of plastic. Each sponge disc 100 has an opening 103 at its center. The opening 103 allows a wire 104 to pass through the center of the positioning disc 102, the connecting piece 101, and the sponge disc 100. The opening 103 penetrates the connecting piece 101 and all the positioning discs 102. The disc 102 is used to hold two sponge discs 100. An iron wire 104 is provided in the opening 103. The iron wire 104 is used to connect the sponge disc 100, the connecting piece 101 and the positioning disc 102 into a whole, forming a cylindrical shape. Each positioning disc 102 has a positioning component 200 on the side away from the connecting piece 101. The positioning component 200 is used to connect the iron wire 104 to the sponge disc 100. Each positioning component 200 is hinged to the iron wire 104. A linkage ring 300 is provided at the end of the iron wire 104 away from the connecting piece 101. The linkage ring 300 and the iron wire 104 can be wound together. A rotating device 301 is rotatably provided at the end of the linkage ring 300 away from the connecting piece 101. The rotating device 301 is used to drive the positioning component 200 to rotate. A sliding device 400 is movably provided at the bottom of the rotating device 301. The sliding device 400 is used to drive the rotating device 301 to move, thereby adjusting the distance between the positioning device and the sponge disc 100 in the pipe.

[0023] In use, the two sponge discs 100 are fixed together by the positioning component 200 and the wire 104 to form a cylinder that fits the inner wall of the pipe. The edge of the sponge disc 100 fits against the inner wall of the pipe. The rotating device 301 drives the wire 104 to rotate, which in turn drives the positioning component 200 and the sponge disc 100 to rotate. The sliding device 400 moves the rotating device 301, thereby pulling the sponge disc 100 along the axial direction of the pipe. This allows the rotating sponge disc 100 to carry the acid paste liquid and evenly coat the inner wall of the pipe, thereby reducing the cost of pipe lining and improving production efficiency.

[0024] This embodiment provides a coating fixture for pipe lining.

[0025] like Figure 1 , 2 As shown in Figure 3: Each positioning component 200 includes a positioning rod 201 that fits onto the opening 103. The positioning rod 201 can be made of wood. The positioning rod 201 is used to fix the positioning disk 102 and also to prevent the positioning disk 102 and the sponge disk 100 from falling off. The middle part of each positioning rod 201 is connected to the wire 104. A positioning buckle 202 is fixedly installed on both sides of the middle part of each positioning rod 201. The positioning buckle 202 can be made of steel wire to connect and fix the positioning disk 102 and the positioning rod 201. The positioning buckle 202 is used to reinforce the connection between the positioning rod 201 and the positioning disk 102, so that the two positioning components 200 form a clamping component to clamp and fix the pair of sponge disks 100 in the middle. The positioning buckle 202 is arc-shaped. The two ends of each positioning buckle 202 pass through the positioning disk 102 on the same side and are hinged together. The steel wire of the positioning buckle 202 can also pass through the sponge disk 100 and be hinged.

The motor bracket 303 is used to mount the drive motor 304. The motor bracket 303 is an L-shaped plate. The drive motor 304 is provided on the bearing surface at the rear of the motor bracket 303. The drive motor 304 is used to drive the linkage rod 302 to rotate, thereby causing the linkage ring 300 connected to the linkage rod 302 to drive the wire 104 to rotate, thereby driving the positioning plate 102 and... The sponge disc 100 rotates inside the pipe. The drive motor 304 drives the connecting shaft 306 to rotate, which in turn drives the linkage plate fixed to the connecting shaft 306 to rotate, thereby causing the wire 104 and the sponge disc 100 connected to its front end to rotate. A coupling 305 is embedded in the motor bracket 303. The coupling 305 is embedded in the vertical plate of the motor bracket 303. The coupling 305 is used to rotatably connect the drive motor 304 and the connecting shaft 306. One end of the coupling 305 is rotatably connected to the output shaft of the drive motor 304, and the other end of the coupling 305 is rotatably connected to the connecting shaft 306. The connecting shaft 306 is used to connect the linkage rod 302 to the drive motor 304. The connecting shaft 306 is connected to the linkage rod 302. One end of the connecting shaft 306 is welded to the linkage rod 302, and the other end of the connecting shaft 306 is rotatably connected to the bearing.

[0028] Its effect is as follows: the linkage rod 302 is used to connect the linkage ring 300 to the connecting shaft 306, the linkage ring 300 is used to connect the wire 104 to the linkage rod 302, the motor bracket 303 is used to install the drive motor 304, thereby causing the linkage ring 300 connected to the linkage rod 302 to drive the wire 104 to rotate, thereby causing the positioning plate 102 and the sponge plate 100 to rotate in the pipe, and the drive motor 304 is used to drive the connecting shaft 306 and the linkage rod 302 to rotate, thereby causing the linkage plate fixed to the connecting shaft 306 to rotate, thereby causing the wire 104 and the sponge plate 100 connected to its front end to rotate.

[0029] like Figure 3 , 4 As shown: The bottom of the drive motor 304 is provided with a motor base 307. The motor base 307 is fixed to the drive motor 304 by bolts. The motor base 307 is fixed to the motor bracket 303 by bolts. The motor base 307 is used to install the drive motor 304, so that the drive motor 304 is connected to the motor bracket 303. The motor base 307 and the motor bracket 303 are fixed by bolts.

[0030] Its function is as follows: the motor base 307 is used to install the drive motor 304, so that the drive motor 304 is connected to the motor bracket 303, and is used to support the drive motor 304.

[0031] like Figure 2 , 3 As shown in Figure 4, the sliding device 400 includes a slide rail 401 for moving the slider 402. The slider 402 is slidably mounted on the front end of the slide rail 401, and the slide rail 401 and slider 402 are slidably engaged. The slider 402 connects the support block 403 to the slide rail 401, thereby connecting the motor bracket 303 connected to the support block 403. Thus, when the slider 402 moves, the motor bracket 303 and the drive motor 304 move synchronously. The top of the slider 402 is provided with a support block 403. The bottom of the support block 403 can be welded to or bolted to the slider 402, and the top of the support block 403 is connected to the motor...

The telescopic end of the electric push rod 404 is fixed to the motor bracket 303 by bolts. The electric push rod 404 is used to push the motor bracket 303 to move along the track of the slide rail 401.

[0033] Working principle: Two sponge discs 100 are fixed together by the positioning component 200 and the wire 104 to form a cylinder that fits the inner wall of the pipe. Acid paste is then poured into the inner wall of the pipe, and the cylinder formed by the sponge discs 100 is placed at one end of the pipe, with the edge of the sponge discs 100 adhering to the inner wall of the pipe. This allows the sponge discs 100 to adhere to the acid paste and evenly coat the inner wall of the pipe. The wire 104 is then connected to the rotating device 301, causing the wire 104 to rotate. This, in turn, drives the positioning component 200 and the sponge discs 100 to rotate. The sliding device 400 moves the rotating device 301, pulling the sponge discs 100 along the axial direction of the pipe. This allows the rotating sponge discs 100 to carry the acid paste and evenly coat the inner wall of the pipe, thereby reducing the cost of pipe lining and improving production efficiency.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
