Description

Technical Field

[0001] This utility model belongs to the field of tubular metal processing technology, and in particular relates to a device for anti-corrosion spraying of the inner wall of tubular metal. Background Technology

[0002] After the metal workpiece is manufactured, it needs to be treated for rust prevention and corrosion prevention. Currently, for metal workpieces, especially metal pipes, rust prevention and corrosion prevention are generally carried out by two methods: immersion and spraying. The outer surface of the metal workpiece can be quickly sprayed.

[0003] However, spraying the inner wall of a metal workpiece is inefficient due to the narrow space inside the workpiece, making it difficult to move in and out. It also easily leads to uneven spraying, affecting the performance. Utility Model Content

[0004] The purpose of this utility model is to provide a tubular metal inner wall anti-corrosion spraying device to solve the problem that the spraying work on the inner wall of metal workpieces is inefficient due to the small space inside the workpiece, making it difficult to enter and exit, and also prone to uneven spraying, which affects the use effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a tubular metal inner wall anti-corrosion spraying device, comprising a base and a conveying assembly. The conveying assembly includes a tube placement groove plate, which is V-shaped. The bottom of the tube placement groove plate is fixedly connected to the base. Several rollers are rotatably connected to both sides and the bottom surface inside the tube placement groove plate. An mounting plate is fixedly connected to one end of the base. The mounting plate is located on one side of the tube placement groove plate. A spray box is mounted on one surface of the mounting plate. A spray tube is installed inside the spray box. At least two sets of nozzles are mounted around the spray tube. The nozzles are located above the tube placement groove plate. Several sets of mounting blocks are fixedly connected to both sides of the tube placement groove plate. A cylinder is mounted on the upper surface of the mounting block. A mating block is fixedly connected to the output end of the cylinder. Several sets of hinge seats are fixedly connected to both sides of the upper surface of the tube placement groove plate. A linkage block is hinged inside the hinge seat. One end of the linkage block is hinged to the mating block. The linkage block is located on one side of the nozzle.

[0007] A micro motor is installed at the other end of the linkage block. A groove is provided on one side of the bottom surface of the linkage block. A drive wheel is rotatably connected inside the groove. The output end of the micro motor is fixedly connected to the drive wheel.

[0008] The nozzle is cylindrical, and several nozzles are installed in a ring around the periphery of the nozzle, with at least two sets of nozzles installed in a staggered arrangement.

[0009] One end of the spray box is equipped with a connecting hose; by setting the connecting hose, an anti-corrosion spray box can be connected to the outside, so that the anti-corrosion spray can enter the spray box through the connecting hose, and then be sprayed onto the inner wall of the metal pipe by the spray pipe and nozzle.

[0010] The drive wheel is coated with an anti-slip coating. By setting the anti-slip coating and uniformly adding hard abrasives such as sand and ceramic particles to the coating, the roughness of the contact surface can be significantly increased while avoiding uneven wear, thereby improving the friction and enabling the drive wheel to move the metal pipe.

[0011] This utility model has the following beneficial effects:

[0012] This invention, through the setting of a conveying component, a spray pipe, and a nozzle, places the metal pipe to be sprayed on a pipe-holding groove plate, with the spray pipe and nozzle positioned inside the metal pipe. Then, a cylinder is activated to drive a linkage block downwards, causing a drive wheel to press against the surface of the metal pipe. A micro motor drives the drive wheel to rotate, and with the assistance of several rollers, the metal pipe moves along the pipe-holding groove plate due to friction between the drive wheel and the surface of the metal pipe. Simultaneously, an external anti-corrosion spraying box introduces anti-corrosion spray into the spray pipe and nozzle. Combined with the movement of the metal pipe, at least two sets of nozzles gradually spray the inner wall of the metal pipe. The nozzles of the multiple sets of nozzles are staggered to ensure uniform spraying, thereby improving spraying efficiency to a certain extent. The operation is simple, reducing the workload of workers.

[0023] Please see Figures 1-3As shown, this utility model is a tubular metal inner wall anti-corrosion spraying device, including a base 1 and a conveying assembly 2. The conveying assembly 2 includes a tube placement groove plate 201, which is V-shaped. The bottom of the tube placement groove plate 201 is fixedly connected to the base 1. Several rollers 202 are rotatably connected to both sides and the bottom surface inside the tube placement groove plate 201. An installation plate 101 is fixedly connected to one end of the base 1. The installation plate 101 is disposed on one side of the tube placement groove plate 201. A spray box 3 is installed on one surface of the installation plate 101. A spray tube 301 is installed inside the spray box 3. At least two sets of spray nozzles 303 are installed around the spray pipe 301. The spray nozzles 303 are located above the pipe placement groove plate 201. Multiple sets of mounting blocks 203 are fixedly connected to both sides of the pipe placement groove plate 201. A cylinder 204 is installed on the upper surface of the mounting block 203. A mating block is fixedly connected to the output end of the cylinder 204. Multiple sets of hinge seats 205 are fixedly connected to both sides of the upper surface of the pipe placement groove plate 201. A linkage block 206 is hinged inside the hinge seat 205. One end of the linkage block 206 is hinged to the mating block. The linkage block 206 is located on one side of the spray nozzle 303.

[0024] A micro motor 208 is installed at the other end of the linkage block 206. A groove is provided on one side of the bottom surface of the linkage block 206. A drive wheel 207 is rotatably connected inside the groove. The output end of the micro motor 208 is fixedly connected to the drive wheel 207.

[0025] The nozzle 303 is cylindrical, and several nozzles are installed in a ring around the circumference of the nozzle 303. At least two sets of nozzles 303 have nozzles installed in a staggered manner.

[0026] One end of the spray box 3 is equipped with a connecting hose 302; by setting the connecting hose 302, an anti-corrosion spray box can be connected to the outside, so that the anti-corrosion spray can enter the spray box 3 through the connecting hose 302, and then be sprayed onto the inner wall of the metal pipe by the spray pipe 301 and the nozzle 303.

[0027] The drive wheel 207 has an anti-slip coating on its circumferential side. By setting the anti-slip coating and uniformly adding hard abrasives such as sand and ceramic particles to the coating, the roughness of the contact surface can be significantly increased while avoiding uneven wear, thereby improving the friction and enabling the drive wheel 207 to drive the metal pipe to move.

[0028] It should be noted that a controller (not shown in the figure) and a solenoid valve (not shown in the figure) are installed on one side of the base 1. The controller is externally powered, and the solenoid valve is electrically connected to the controller and to multiple sets of cylinders 204. The solenoid valve controls the synchronous operation of the multiple sets of cylinders 204. Multiple sets of micro motors 208 are electrically connected to the controller. In actual use, the anti-corrosion spraying box is connected to the connecting hose 302. The metal fitting to be sprayed is placed on the pipe placement plate 201 and brought closer to the mounting plate 101, so that the spraying pipe 301 and the nozzle 303 are inside the metal fitting. Then, the cylinder 204 is activated to drive the linkage block 206 to swing down, so that the drive wheel 207 presses against the surface of the metal fitting. The micro motor 208 drives the drive wheel 207 to rotate, and with the help of several rollers 202, the drive wheel 207 presses against the surface of the metal fitting. Under the friction between them, the metal pipe moves along the pipe placement groove plate 201 and gradually moves away from the mounting plate 101. At the same time, the external anti-corrosion spray box introduces anti-corrosion spray into the spray pipe 301 and the nozzle 303. With the movement of the metal pipe, at least two sets of nozzles 303 gradually spray the inner wall of the metal pipe. The nozzles of the multiple sets of nozzles 303 are staggered to make the spraying as uniform as possible, which improves the spraying efficiency to a certain extent. The operation is simple and reduces the workload of the staff.
