Description

Technical Field

[0001] This utility model belongs to the field of spiral steel pipe processing technology, specifically a device for cleaning the inner wall of wear-resistant spiral steel pipe. Background Technology

[0002] Spiral steel pipe is a type of steel pipe made by rolling strip steel into a pipe blank at a certain spiral angle and then welding it. During the external welding of spiral steel pipe, molten metal flows into the weld seam, forming weld beads. These weld beads affect the performance of the pipe. Therefore, ensuring unobstructed internal flow and a clean inner wall is a fundamental requirement for spiral steel pipe. According to the patent document CN202479939U, entitled "A Device for Cleaning the Inner Wall of Spiral Steel Pipe," it consists of a support, a cleaning mechanism, and a motor. The motor is fixed to one end of the support, and the cleaning mechanism connected to the motor is fixed to the other end. The cleaning mechanism consists of a probe arm, a shock-absorbing sleeve, a grinding wheel, and a light. A shock-absorbing sleeve is fitted onto the probe arm near the motor. A grinding wheel that can move up and down is mounted on the front end of the probe arm via a pin. A light is fitted onto the shock-absorbing sleeve. However, the following defects still exist:

[0003] When performing the cleaning work, the operator needs to hold the cleaning device on the inner wall of the spiral steel pipe for a long time. Since the cleaning device has a certain weight, the operator will quickly exhaust the operator's physical strength by holding it for a long time, which will bring inconvenience to the use of the cleaning device. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a wear-resistant spiral steel pipe inner wall cleaning device, which effectively solves the problem of inconvenience caused by the current manual lifting cleaning device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant spiral steel pipe inner wall cleaning device, including a mounting frame, wherein the mounting frame is provided with a support mechanism and a cleaning mechanism;

[0006] The support mechanism includes multiple U-shaped round rods fixed at equal angles to the outside of the mounting frame. A U-shaped plate is movably sleeved on the outside of each U-shaped round rod. Two movable wheels are symmetrically arranged on the U-shaped plate. A screw is rotatably connected inside the mounting frame. One end of the screw extends to the outside of the mounting frame and is fixedly connected to a handwheel. A threaded sleeve is threaded onto the outside of the screw. Multiple sliders are fixedly connected at equal angles to the outside of the threaded sleeve. A drive rod is rotatably connected to the outside of the sliders. The end of the drive rod away from the slider is rotatably connected to the U-shaped plate.

[0007] Preferably, the mounting frame is provided with multiple sliding grooves at equal angles, and each slider is slidably connected to each sliding groove.

[0022] Example 1, by Figure 1 The present invention relates to a wear-resistant spiral steel pipe inner wall cleaning device, including a mounting frame 1, on which a support mechanism 2 and a cleaning mechanism 3 are provided.

[0023] Specifically, by Figure 2 The support mechanism 2 includes multiple U-shaped round rods 201 fixed at equal angles to the outside of the mounting frame 1. A U-shaped plate 2011 is movably sleeved on the outside of each U-shaped round rod 201. Two movable wheels 202 are symmetrically arranged on the U-shaped plate 2011. A screw 208 is rotatably connected inside the mounting frame 1. One end of the screw 208 extends to the outside of the mounting frame 1 and is fixedly connected to a handwheel 207. A threaded sleeve 204 is threaded onto the outside of the screw 208. Multiple sliders 203 are fixedly connected at equal angles to the outside of the threaded sleeve 204. The outer sides of the sliders 203 rotate... A drive rod 2010 is connected, and the end of the drive rod 2010 away from the slider 203 is rotatably connected to the U-shaped plate 2011. Multiple sliding grooves 209 are provided at equal angles on the mounting frame 1, and each slider 203 is slidably connected to each sliding groove 209. A handle 205 is fixedly connected to the outside of the mounting frame 1, and a rubber sleeve 206 is fixedly sleeved on the middle of the outside of the handle 205. By setting the rubber sleeve 206 and the handle 205, it is easy for the operator to pick up the mounting frame 1. An illumination light is provided on the outside of the mounting frame 1 to make it easy to see the internal condition of the spiral steel pipe.

[0024] In use, the mounting frame 1 is first placed inside the spiral steel pipe. Then, the handwheel 207 is rotated to drive the screw 208 to rotate. The screw sleeve 204 drives each slider 203 to slide along each groove 209. Then, each drive rod 2010 drives each U-shaped plate 2011 to slide along each U-shaped round rod 201. At the same time, each moving wheel 202 moves until it abuts against the inner wall of the spiral steel pipe. Finally, the mounting frame 1 moves inside the spiral steel pipe through each moving wheel 202, eliminating the need for manual lifting and improving the efficiency of subsequent cleaning.

[0025] Specifically, by Figure 3 The cleaning mechanism 3 includes a mounting plate 301 fixed to the outside of the mounting frame 1. A drive motor 3013 is fixedly mounted on the side of the mounting plate 301 away from the mounting frame 1. A drive shaft 3011 is fixedly connected to the drive motor 3013. A side plate 307 is fixedly connected to the end of the drive shaft 3011 away from the drive motor 3013. A mounting plate 302 is provided above the side plate 307. A grinding motor 305 is fixedly mounted on the top of the mounting plate 302. A grinding shaft 304 is fixedly connected to the grinding motor 305. The top end of the grinding shaft 304 is fixed... A grinding wheel 303 is connected to the bottom of the mounting plate 302, and a U-shaped round rod 3010 is fixedly connected to the bottom of the mounting plate 302. The U-shaped round rod 3010 passes through the side plate 307 and is movably connected to the side plate 307. A sleeve block 309 is fixedly sleeved on the middle of the outer side of the U-shaped round rod 3010. A cylinder 308 is fixedly installed between the top of the sleeve block 309 and the bottom of the side plate 307. Two support columns 306 are symmetrically fixedly connected to the outer side of the side plate 307. Each of the two support columns 306 is provided with a support ball 3012 that abuts against the mounting plate 301 at the end away from the side plate 307.

[0026] In operation, the grinding motor 305 is first started, which drives the grinding shaft 304 to rotate and the grinding wheel 303 to rotate. Then, the cylinder 308 is started, which drives the U-shaped rod 3010 to move through the sleeve block 309 and moves the mounting plate 302. At the same time, the grinding wheel 303 moves until it abuts against the inner wall of the spiral steel pipe to achieve the cleaning operation. When the drive motor 3013 is started, it drives the drive shaft 3011 to rotate and the side plate 307 to rotate. At the same time, the two support balls 3012 roll on the mounting plate 301 to ensure the stability of the side plate 307 during rotation. Finally, the grinding wheel 303 rotates in a circular motion to adjust its position.
