Description

Technical Field

[0001] This utility model relates to a pipe cleaning device, specifically a percussion-type electric pipe cleaning device. Background Technology

[0002] Many factories and businesses clean the rust, flaking debris, and other deposits from the pipes of boilers and other equipment before use and after a period of use to keep the pipes unobstructed and extend their service life. Common cleaning methods typically involve high-pressure water flushing; however, stubborn, hard deposits are difficult to remove and often require manual physical breaking up – a very inefficient method. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a percussion-type electric pipe cleaning device that can replace manual labor and has higher cleaning efficiency.

[0004] The technical solution of this utility model is: a striking electric pipe cleaning device, including a housing, a drive motor, several hammers, and a transmission mechanism consisting of a swing arm and an inner cam. The housing is a cylindrical body with open ends. Several traveling wheels are provided around the outer wall of the housing. A rope connection part is also provided on the outer wall of the housing. A hinge frame is provided around the inner wall of the housing near one end. The swing arm is axially arranged inside the housing. The swing arm is hinged to the hinge frame and arranged in a ring inside the housing. One end of the swing arm is connected to the hammers through a spring. The hammers extend out of the housing. The other end of the swing arm is provided with a roller. A return spring is also connected to the swing arm to pull the hammers toward the axis of the housing. The inner cam has at least one raised part in the direction of the axis on its contour surface. The inner cam is connected to the output shaft of the drive motor and is coaxially arranged inside the housing. The roller on the swing arm abuts against the contour surface of the inner cam.

[0005] The technical advantages of this invention are: reasonable structural design, convenient operation, good effect, and high cleaning efficiency. By using a motor to drive a small ball to tap the inner wall of the pipe, not only are stubborn deposits at the tapping point quickly removed, but the pipe also vibrates synchronously under the tapping, causing nearby deposits to vibrate and gradually loosen and fall off, resulting in a very ideal cleaning effect.

Detailed Implementation

[0007] like Figure 1 ,2 As shown in Figure 3, the striking-type electric pipe cleaning device includes a housing 1, a drive motor 2, several hammers 3, and a transmission mechanism consisting of a swing arm 4 and an inner cam 5. The housing 1 is a cylindrical body open at both ends. Several wheels 6 are provided around the outer wall of the housing 1. A rope connection part 7 is also provided on the outer wall of the housing 1 for connecting ropes to drag the cleaning device inside the pipe. The ropes can be connected in one direction to drag the cleaning device from one end of the pipe to the other, or they can be connected in both directions to allow the cleaning device to move back and forth inside the pipe by being dragged from both ends. A hinge frame 8 is provided around the inner wall of the housing 1 near one end. The swing arm 4 is axially arranged inside the housing 1. The swing arm 4 is hinged to the hinge frame 8 and arranged in a ring inside the housing 1. One end of the swing arm 4 is connected to the hammer head 3 through the spring 9. The hammer head is a small metal ball and extends out of the housing 1. The other end of the swing arm 4 is provided with a roller 10. The swing arm 4 is also connected with a return spring 11 that pulls the hammer head 3 toward the axial direction of the housing 1. The inner cam 5 has at least one raised part 12 in the axial direction on its contour surface. The inner cam 5 is connected to the output shaft of the drive motor 2 and is coaxially arranged inside the housing 1. The roller 10 on the swing arm 4 abuts against the contour surface of the inner cam 5.

[0008] There are two raised portions 12, which are evenly distributed on the contour surface of the inner cam 5. They are symmetrically positioned to counteract eccentric forces.

[0009] A spring plate 14 is connected inside the housing 1 via a bracket 13. One end of the return spring 11 is connected to the swing rod 4, and the other end is connected to the spring plate 14.

[0010] A fan 15 is also connected to the motor shaft of the drive motor 2. The spokes of the cam have holes to facilitate ventilation. When the fan rotates, it generates airflow towards the hammer head, which serves to cool the motor and blow away dust generated by the hammering from the machine body.

[0011] A fan cover 16 is provided on the housing 1 at one end near the drive motor 2.
