Description

Technical Field

[0001] This utility model relates to the field of cold-rolled tube cleaning technology, specifically a device for cleaning the inner wall of cold-rolled tubes. Background Technology

[0002] Cold-rolled seamless steel pipe is a type of steel pipe used in precision mechanical structures, hydraulic equipment, or reinforcing bar sleeves. Its characteristics include high dimensional accuracy and good surface finish. Cold-rolled steel pipe has high precision, high strength, and good surface quality, making it suitable for a variety of industrial applications.

[0003] During the processing and use of cold-rolled pipes, some cold-rolling oil or particulate matter may remain inside the pipe. In this case, the inside of the cold-rolled pipe is often cleaned by rinsing with water. However, the impact force of the water flow is significantly reduced after entering the inside of the cold-rolled pipe. Without an auxiliary structure to wipe the inner wall, it is difficult to clean the inner wall thoroughly. Therefore, it is necessary to design a cold-rolled pipe inner wall cleaning device. Utility Model Content

[0004] The purpose of this invention is to provide a device for cleaning the inner wall of cold-rolled tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a water tank and a cleaning column. A pair of adjusting plates are installed on the upper end of the water tank, and pipe clamps are fixed on the adjusting plates. External supports are fixed on both sides of the water tank. A reel is rotatably connected to the external support, and a synchronous motor that drives the reel to rotate synchronously is fixed thereon. A steel wire is wound around the reel, and a cleaning column is installed at the end of the steel wire. Brush bristles are fixed around the periphery of the cleaning column. A limiting component for adjusting the height of the adjusting plates is provided at the upper end of the water tank. A water pipe bracket is fixed to the upper side wall of the water tank, and a water outlet pipe is fixed on the water pipe bracket. A solenoid valve is fixed on the water outlet pipe.

[0006] Preferably, the limiting component includes a fixing sleeve, a vertical rod, and an adjusting bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are: a cleaning column that is compatible with the inner diameter of the cold-rolled pipe is fixed on a steel wire and extends into the cold-rolled pipe. While continuously injecting water, the cleaning column is slid back and forth by the steel wire, so as to achieve rapid wiping and cleaning of the inner wall. This solves the problem that it is difficult to clean with water. Moreover, for different pipe diameters, only the appropriate cleaning column needs to be replaced, which is simple and convenient to operate. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: including a water tank 1 and a cleaning column 5. A pair of adjusting plates 41 are installed on the upper end of the water tank 1. A pipe clamp 4 is fixed on the adjusting plate 41. An outer bracket 2 is fixed on both sides of the water tank 1. A spool 21 is rotatably connected to the outer bracket 2, and a synchronous motor 22 is fixed to drive the spool 21 to rotate synchronously. A steel wire 3 is wound on the spool 21. A cleaning column 5 is installed at the end of the steel wire 3. Brush bristles 51 are fixed around the cleaning column 5. A limiting component for adjusting the height of the adjusting plate 41 is provided at the upper end of the water tank 1. A water pipe bracket 6 is fixed on the upper side wall of the water tank 1. A water outlet pipe 61 is fixed on the water pipe bracket 6. A solenoid valve 62 is fixed on the water outlet pipe 61.

[0018] The limiting assembly includes a fixing sleeve 42, a vertical rod 43, and an adjusting bolt 45. The fixing sleeve 42 is fixed to the outer side of the upper end of the water tank 1. The vertical rod 43 is fixed to the bottom of both ends of the adjusting plate 41. The bottom of the vertical rod 43 passes through the fixing sleeve 42 and is threadedly connected to a positioning nut 44. The adjusting bolt 45 is threadedly connected to the upper end of the water tank 1 and is located below the adjusting plate 41. A support plate 46 is fixed to the upper end of the adjusting bolt 45. The upper end of the support plate 46 abuts against the bottom of the adjusting plate 41. Fixing brackets 11 are fixed on both sides of the upper end of the water tank 1. A guide wheel 12 is fixed to the upper end of the fixing bracket 11. The position of the guide wheel 12 is aligned with the center position of the pipe clamp 4.

[0019] A filter screen 13 is fixed inside the water tank 1. The end of the water outlet pipe 61 away from the water pipe bracket 6 is fixed to the bottom side wall of the water tank 1. A water pump is installed on the water outlet pipe 61. The upper part of the water tank 1 is an inclined structure, and the height of the end near the water outlet pipe 61 is higher than the height of the other end.

[0020] The ends of the steel wire 3 are respectively fixed with a fixing block 31 and a connecting block 33. The cleaning column 5 has positioning grooves 52 on both sides. The fixing block 31 is inserted into the positioning groove 52 and fixed with a rod 32. The connecting block 33 is inserted into the positioning groove 52 and has a threaded groove 34 at its end. The end of the rod 32 passes through the cleaning column 5 and is threaded into the threaded groove 34.

[0021] Working principle: First, connect the entire device to an external power source and fix the cold-rolled tube between the pipe clamps 4. Then, pass the steel wire 3 through the cold-rolled tube and fix it to the cleaning column 5. After fixing, pull the cleaning column 5 into the cold-rolled tube. At this time, water can be continuously injected into the cold-rolled tube through the outlet pipe 61. The synchronous reciprocating rotation of the reel 21 can pull the cleaning column 5 to slide back and forth inside the cold-rolled tube, continuously wiping the inner wall of the cold-rolled tube to ensure that the inner wall is clean. During this process, the water in the tank 1 is sprayed out from the outlet pipe 61 by the water pump and then enters the cold-rolled tube. Because the outlet pipe 61 is higher on one side, the water will flow to a lower position inside the cold-rolled tube, thus passing through the cold-rolled tube. When cleaning cold-rolled pipes of different diameters, the height of the pipe clamp 4 needs to be adjusted to ensure that the steel wire 3 passes through the center of the cold-rolled pipe. At this time, by rotating the positioning nut 44, its height at the bottom of the upright 43 can be changed, thereby limiting the upward adjustment of the upright 43 and the adjusting plate 41. By rotating the adjusting bolt 45, the height of the support plate 46 can be changed, thereby adjusting the downward height of the adjusting plate 41, and thus adjusting the position of the pipe clamp 4, ensuring that the steel wire rope can pass through the center of the cold-rolled pipe. At the same time, by rotating the connecting block 33, the connection between the connecting block 33 and the insert rod 32 can be quickly disconnected, facilitating the disassembly and assembly of the cleaning column 5, and replacing it with a cleaning column 5 that matches the inner diameter of the cold-rolled pipe for cleaning operations.
