It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

The base frame 1 is rotatably connected to a plurality of support wheels 3 and power wheels 4 used in conjunction with the pipelines 2 through bearings. The support wheels 3 are used to support the pipelines 2 in rotation. The power wheels 4 rotate under the drive of existing power structures such as motors, thereby driving the pipelines 2 in contact with them to rotate around the center line. The support wheels 3 and power wheels 4 are in rolling contact with the bottom of the pipelines 2. Under the rotation support of multiple support wheels 3, the pipelines 2 can maintain a rotating state without slipping off the support wheels 3. 1 is connected to a movable frame 5 along the horizontal sliding direction, and a power assembly for driving the movable frame 5 to slide along the horizontal direction is provided on the base frame 1. Under the action of the power assembly, the movable frame 5 can move horizontally along the axial direction of the pipeline 2 to realize the gradual rust removal operation on the peripheral side of the pipeline 2. A rust removal frame 6 is connected to the movable frame 5 along the vertical sliding direction. A plurality of rust removal wheels 7 are rotatably connected to the rust removal frame 6 through bearings. A wire brush is provided on the surface of the rust removal wheel 7 so that it rotates and removes rust when it contacts the surface of the pipeline 2. The rust removal wheel 7 is in rolling contact with the top of the pipeline 2. Such a structure makes the pipeline 2 placed on the base frame 1 moves forward, the rust removal frame 6 slides upward to leave space for the placement of the pipe 2. After the pipe 2 is placed on the supporting wheel 3 and the power wheel 4 of the base frame 1, the rust removal frame 6 drives the rust removal wheel 7 to slide downward until the rust removal wheel 7 contacts the top of the pipe 2, thereby effectively restricting the pipe 2, ensuring the smooth rotation of the pipe 2 and the stability during the rotation process, and ensuring the effect of rust removal on the surface of the pipe 2. During the rust removal process, there is no need to manually flip and hoist the pipe 2, which simplifies the rust removal steps and greatly improves the rust removal efficiency. The rust removal frame 6 is provided with a sliding rod 8 and a rotating pressure rod 9. The pressure rod 9 is connected to the The rust removal frame 6 is rotatably connected, the pressure rod 9 passes through the movable frame 5 and is threadedly connected thereto, and the slide rod 8 passes through the movable frame 5 and is slidably connected thereto. Such a structure only needs to rotate the pressure rod 9 to drive the rust removal frame 6 and the slide rod 8 to slide up and down relative to the movable frame 5 under the action of the threaded connection. After the rust removal frame 6 drives the rust removal wheel 7 to contact the top of the pipe 2, the threaded connection between the pressure rod 9 and the movable frame 5 can also enable the rust removal wheel 7 to maintain a downward pressure restriction state on the pipe 2, further ensuring the stability of the pipe 2 during rust removal, ensuring the uniformity of rust removal on the surface of the pipe 2, and making the rust removal operation on the surface of the pipe 2 more thorough.

[0022] Preferably, the support wheel 3 and the rust removal wheel 7 are symmetrically arranged on both sides of the pipeline 2. Such a structure enables the support wheels 3 symmetrically arranged on both sides to support the pipeline 2 more stably. The power wheel 4 is arranged between the support wheels 3 on both sides, ensuring the stability of the rotation of the pipeline 2. The structure in which the rust removal wheels 7 are symmetrically arranged on both sides makes the contact area between the rust removal wheels 7 and the pipeline 2 larger. When the pipeline 2 rotates the same number of times, the number of rust removal rotations is greater, further improving the efficiency of rust removal.

[0023] Preferably, refer to Figure 4 , guide grooves 10 are symmetrically provided on both sides of the base frame 1, and the guide grooves 10 are formed by welding channel steel or fixing them on the base frame 1 with bolts. The bottom of the movable frame 5 is symmetrically welded or bolted with guide blocks 11, and the guide blocks 11 are slidably connected in the guide grooves 10. The cooperation between the guide blocks 11 and the guide grooves 10 makes the movable frame 5 more stable when sliding horizontally relative to the base frame 1, thereby making the contact between the rust removal wheel 7 and the pipe 2 more stable, ensuring the accuracy of the rust removal wheel 7 in rotating contact and rust removal on the pipe 2. The bottom of the guide block 11 is rotatably connected to the movable wheel 12 through a bearing, and the movable wheel 12 is in rolling contact with the bottom of the guide groove 10. The setting of the movable wheel 12 makes the lateral movement of the movable frame 5 relative to the base frame 1 become a rolling state, the friction resistance of the movement is smaller, and the movement is smoother.

[0024] Preferably, refer to Figure 3 The power assembly includes a power rod 13 and a guide rod 14. Sliders 15 are symmetrically welded or bolted on the mobile frame 5. The power rod 13 passes through the slide 15 on one side and is threadedly connected to it. The guide rod 14 passes through the slide 15 on the other side and is slidably connected to it. The power rod 13 is driven to rotate by a motor. Such a structure allows the mobile frame 5 to slide laterally along the guide rod 14 under the action of the threaded connection when the power rod 13 rotates, so that the lateral sliding control of the mobile frame 5 is more accurate, ensuring better connection between the front and rear rust removal areas, and making the rust removal more uniform and thorough.

[0025] Preferably, the base frame 1 is rotatably connected to a plurality of rotating shafts 16 through bearings, the support wheels 3 and the power wheels 4 are respectively welded or bolted to the plurality of rotating shafts 16, and the base frame 1 is provided with a rotating motor 17 for driving the rotating shaft 16 where the power wheels 4 are located to rotate. Such a structure utilizes the motor to drive the rotating shaft 16 and the plurality of power wheels 4 thereon to rotate simultaneously, making the rotation drive of the longer pipe 2 more efficient and stable.

[0026] Preferably, a rotating wheel 18 is welded or bolted to the top of the pressure rod 9. During operation, the pressure rod 9 can be quickly driven to rotate by rotating the rotating wheel 18, making the up and down movement of the rust removal frame 6 more labor-saving.

[0027] Working principle: The utility model is provided with a support wheel 3 for carrying the pipe 2 and a power wheel 4 for driving the pipe 2 to rotate on the base frame 1. When the pipe 2 is placed on the base frame 1, the support wheel 3 and the power wheel 4 are in uniform rolling contact with the bottom of the pipe 2. A movable frame 5 is connected to the base frame 1 along the horizontal sliding direction, and a rust removal frame 6 is provided on the movable frame 5 along the vertical sliding direction. A plurality of rust removal wheels 7 are rotatably connected to the rust removal frame 6, and the rust removal wheel 7 is in rolling contact with the top of the pipe 2. Such a structure enables the rust removal frame 6 to slide downward during rust removal, so that the plurality of rust removal wheels 7 move downward and fit into the top of the pipe 2, pressing the pipe 2 downward and limiting it on the power wheel 4 and the support wheel 3. Such a structure can effectively drive the pipe 2 to rotate around the center line when the power wheel 4 rotates, thereby realizing rapid and uniform rust removal on the circumference of the pipe 2. The rust removal operation does not require turning over and lifting the pipe 2, which greatly simplifies the steps of the rust removal operation, improves the uniformity of rust removal on the outside of the pipe 2, and further improves the efficiency and effect of rust removal; a power component for driving the movable frame 5 to slide horizontally is provided on the base frame 1, so that the movable frame 5 can drive the rust removal frame 6 to move along the axial direction of the pipe 2 for rust removal, making the entire rust removal process smoother and more efficient, and a sliding rod 8 and a rotating pressure rod 9 are provided on the rust removal frame 6. When the pressure rod 9 rotates, the rust removal frame 6 drives the rust removal wheel 7 to move downward under the action of the threaded connection. After the rust removal wheel 7 contacts the pipe 2, the pipe 2 can be effectively pressed against the supporting wheel 3 and the power wheel 4 under the action of the threaded connection, thereby making the position of the pipe 2 more stable during rust removal, and further improving the rust removal effect.
