An auxiliary adjustment member that is adapted to the position of the limit adjustment member 1 is sleeved on the propulsion cylinder, and the auxiliary adjustment member limits the predetermined clamping diameter achieved by the limit adjustment member 1;

[0007] The rust-removing member comprises a rust-removing cylinder rotatably sleeved on the propulsion cylinder, a rust-removing brush in contact with the surface of the pipe and producing a rust-removing effect is arranged inside the rust-removing cylinder, and the rust-removing brush is synchronously adjusted to adapt to the rust-removing operation of pipes of different diameters through a connecting piece installed in the rust-removing cylinder and a limit adjusting piece;

[0008] The first and second limit adjustment members are symmetrically arranged at the left and right ends of the rust cleaning cylinder to assist in adjusting and guiding the movement of the rust cleaning cylinder.

[0009] In a specific embodiment, the limit adjustment member 1 and the limit adjustment member 2 both include a main shaft that passes through the propulsion cylinder, a central shaft is installed at the end of the structure extending in the propulsion cylinder, a sleeve is installed on the extended cut-off surface of the central shaft, the central shaft extends up and down in the main shaft, the sleeve has a diameter greater than the diameter of the central shaft and is connected to the surface of the pipe, a limit arm circumferentially surrounding the central shaft is installed on the sleeve, and the limit arm has three movement positions on the main shaft;

[0010] The main shaft is provided with a first movement position, a second movement position and a third movement position adapted to the width of the limit arm, the opening lengths of the first movement position, the second movement position and the third movement position gradually increase, and the opening length of the third movement position is equal to the maximum movement length of the central shaft in the main shaft;

[0011] The structure of the main shaft on the outer wall of the propulsion cylinder is equipped with a passive gear, and the auxiliary adjustment member meshes with the passive gear during rotation to drive the rotation of the passive gear to adjust the support distance of the main shaft movement adjustment limit arm to the sleeve head.

[0012] In a specific embodiment, the rust cleaning brush includes a plurality of mounting plates annularly mounted on the inner wall of the rust cleaning cylinder, a plurality of brush wires are arranged on the mounting plates, and a structure extending downward from the brush wires mounted on the same mounting plate is provided with a restraining plate to control the end position of its extension, and the restraining plate is connected to the connecting piece.

[0013] In a specific embodiment, the connecting member includes an armature plate disposed on the inner wall of the rust cleaning cylinder and rotating synchronously therewith, a restraining plate connected to the armature plate, a synchronizing ring is disposed at one end of the armature plate away from the restraining plate, a transfer plate connected to the sleeve in the second limit adjustment is connected to the synchronizing ring, a notch adapted to three movement heights of the sleeve is provided on the synchronizing ring, and the transfer plate is connected to the armature plate through the notch;

[0014] The end of the synchronization ring opposite to the armature plate is provided with three concentrically opened convex rings, and the opening spacing of the three convex rings is equal to the length difference between the first movement position, the second movement position and the third movement position.

[0015] In a specific embodiment, it is described that the width of the convex ring is adapted to the width of the transfer plate, and a ring groove adapted to the width of the convex ring is provided on the hinge plate.

[0016] In a specific embodiment, the mounting plate is provided with a cavity adapted to the positions of a plurality of brush filaments, and the length of the cavity is equal to the length difference between the first movement position and the second movement position.

[0017] In a specific embodiment, the top surface of the transfer plate is horizontal to the mounting surface of the limiting arm.

[0018] Compared with the prior art, the present invention provides a wire brush roller that is convenient for removing rust, and has the following beneficial effects:

[0019] In the technical solution disclosed in the present invention, a propulsion member is used to perform adaptive adjustment when it is suitable for pipes of different diameters, and a limit adjustment member 1 and a limit adjustment member 2 that act on the surface of the pipe to produce a clamping effect are pushed toward the surface of the pipe to produce a clamping diameter that is adapted to the diameter of the pipe. On the other hand, based on the basic purpose of the brush wire of the brush roller being connected to the pipe, and in order to ensure that the brush wire will not bend due to excessive length when it comes into contact with the pipe, the extension height of the brush wire in the rust cleaning cylinder is synchronized with the limit adjustment member 1, thereby achieving normal rust cleaning operations on the pipe on the basis of clamping pipes of different diameters.

[0020] In addition to setting the limit adjustment part 1, this scheme also sets the limit adjustment part 2. The limit adjustment part 1 cooperates with the rust cleaning brush to produce synchronous adjustment to achieve adaptation to the diameter of the working pipe, and the limit adjustment part 2 is set before the rust cleaning brush acts on the pipe. It first positions the pipe diameter, thereby producing an adjustment standard before the rust cleaning brush comes out of the pipe. On the other hand, the limit adjustment part 2 can provide certain movement guidance and movement support for the rust cleaning brush, avoiding the centering error between the rust cleaning tube and the pipe caused by the material of the brush wire.

[0021] In this scheme, the adaptability of the limit adjustment piece to a pair of pipes is refined into the supporting distance of the limit arm to the sleeve, and the clamping range of several sleeves is adjusted by adjusting the distance between the sleeve and the main shaft through the limit arm. Based on this idea, as long as the position of three limit arms is adjusted during the adjustment process, the clamping distance of the sleeve to the pipe can be controlled by extending or retracting the limit arm on the main shaft, thereby reducing the intervention of several control structures and sensors and reducing production costs.

[0022] This solves the problem that the corresponding adjustment cannot be made according to different pipe diameters, and the rust removal effect is poor when rust removal is performed on steel pipes with different pipe diameters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 , the specific problem addressed by the embodiments of the present invention is that steel pipes are an indispensable pipe material in construction projects. Due to the long construction period, steel pipes are left naked on construction sites. They will be corroded and rusted after long-term use. If they are not removed in time, using rusted steel pipes may pose a safety hazard. Therefore, it is necessary to remove rust from the steel pipes. The rust removal plate provided in the construction steel pipe rust removal device disclosed in Chinese patent CN202022184614.3 is a flat plate with a brush head, which cannot be adjusted accordingly according to different pipe diameters. When rusting steel pipes of different pipe diameters, the rust removal effect is not good. Based on the above prior art, the diameter mismatch problem of pipes during rust removal, this scheme proposes a wire brush roller that is easy to remove rust. The propeller 2 is used to adjust the adaptability when it is suitable for pipes of different diameters, and the limit adjustment member 1 22 and the limit adjustment member 2 23 that act on the surface of the pipe to produce a clamping effect are pushed toward the surface of the pipe to produce a clamping diameter that is adapted to the diameter of the pipe.

[0033] The present embodiment describes a wire brush roller for rust removal, comprising a sleeve end 1, to which is connected a propulsion member 2 which is synchronously propulsed toward a pipe structure, and to which is sleeved a rust-cleaning member 3 which rotates on the pipe to clean the rust thereon. The sleeve end 1 is sleeved on the pipe in a cylindrical shape, and is placed on the pipe later than the rust-cleaning member 3 and the propulsion member 2. The propulsion member 2 in the present embodiment serves to provide a motion guide for the rust-cleaning member 3 and to provide an adaptive clamping for the pipe, and on the basis of the adaptive clamping for the pipe, can synchronously drive the rust-cleaning member 3 to produce a synchronous range of action adjustment.

[0034] In order to adapt to the diameter of different working pipes, a propeller 2 is provided for adaptive adjustment. The propeller 2 includes a propeller cylinder 21 with a pipe diameter equal to the sleeve end 1. The propeller cylinder 21 is provided with a plurality of limit adjustment members 22 and limit adjustment members 23 for adjusting the clamping adaptability of the propeller 2 to the pipe diameter. The limit adjustment members 1 22 and the limit adjustment members 23 are symmetrically arranged at the left and right ends of the rust cleaning cylinder 31 to assist in adjusting and guiding the movement of the rust cleaning cylinder 31. The limit adjustment one and the limit adjustment two for the diameter adjustment of the pipe are both based on the diameter of the propulsion cylinder 21. The limit adjustment piece one 22 and the limit adjustment piece two 23 both include a main shaft 221 that passes through the propulsion cylinder 21, and a central shaft 222 is installed at the end of the structure extending into the propulsion cylinder 21, and a sleeve 223 is installed on the extended cut-off surface of the central shaft 222. The central shaft 222 extends or retracts in the main shaft 221, and the diameter of the sleeve 223 is larger than the diameter of the central shaft 222 and is connected to the surface of the pipe. A limit arm 224 circumferentially surrounding the central shaft 222 is installed on the sleeve 223, and the limit arm 224 has three movement positions on the main shaft 221. The main shaft 221 is provided with a first movement position 225, a second movement position 226 and a third movement position 227 that are adapted to the width of the limit arm 224. The opening lengths of the first movement position 225, the second movement position 226 and the third movement position 227 gradually increase, and the opening of the third movement position 227 Assuming the length is equal to the maximum movement length of the central axis 222 in the main shaft 221, the structure of the main shaft 221 on the outer wall of the propulsion cylinder 21 is installed with a passive gear 228. The auxiliary adjustment member 24 meshes with the passive gear 228 during rotation to drive the rotation of the passive gear 228 to adjust the support distance of the main shaft 221 movement adjustment limit arm 224 to the sleeve 223. The propulsion cylinder 21 is sleeved with an auxiliary adjustment member 24 that is adapted to the position of the limit adjustment member 22. The auxiliary adjustment member 24 limits the predetermined clamping diameter achieved by the limit adjustment member 22. In this embodiment, the auxiliary adjustment member 24 is a structural member that can mesh with the passive gear 228, which includes a circular ring and teeth installed on the side wall of the circular ring. The circular ring is installed with a number of ring strips for increasing friction. The driving force of the auxiliary adjustment member 24 can be manual or other external existing structures. The selection is based on the specific manufacturer's needs for automation.

[0035] The rust cleaning member 3 includes a rust cleaning cylinder 31 rotatably sleeved on the propulsion cylinder 21, a rust cleaning brush 32 in contact with the surface of the pipe and producing a rust removing effect is arranged inside the rust cleaning cylinder 31, and the rust cleaning brush 32 includes a plurality of mounting plates 321 circumferentially mounted on the inner wall of the rust cleaning cylinder 31, and a plurality of brush wires 322 are arranged on the mounting plates 321. Based on the basic purpose of the brush wires 322 connecting with the pipe, and in order to ensure that the brush wires 322 will not be bent due to excessive length when contacting the pipe, the rust cleaning brush 32 is synchronously adjusted to adapt to the rust removal operation of pipes of different diameters through the connecting piece 33 installed in the rust cleaning cylinder 31 and the limit adjustment piece 22, and the extension height of the brush wire 322 in the rust cleaning cylinder 31 is synchronized with the limit adjustment piece 22, thereby achieving normal rust cleaning of the pipe on the basis of clamping pipes of different diameters. The end position of the extension of the brush wire 322 installed on the same mounting plate 321 is controlled by installing a restraining plate 323 on the structure that extends downward. The mounting plate 321 is provided with a cavity adapted to the position of the brush wire 322. The opening length of the cavity is equal to the length difference between the first movement position 225 and the third movement position 227. The restraining plate 323 is connected to the connecting piece 33. The connecting piece 33 includes a keeper plate 331 that is arranged on the inner wall of the rust cleaning cylinder 31 and rotates synchronously therewith. The restraining plate 323 is connected to the keeper plate 331. The keeper plate 331 is connected to the keeper plate 331. A synchronization ring 332 is provided at one end of the locating plate 31 away from the locating plate 323, and a transfer plate 229 connected to the sleeve 223 in the second limit adjustment is connected to the synchronization ring 332. The length of the brush wire 322 below the locating plate 323 is equal to the distance between the transfer plate 229 and the cut-off surface of the sleeve 223. The bottom surface of the brush wire 322 and the bottom surface of the sleeve 223 are located on the same horizontal line. A notch 333 adapted to the three movement heights of the sleeve 223 is opened on the synchronization ring 332. The transfer plate 229 is connected to the armature plate 331 through the notch 333. The rust cleaning cylinder 31 is marked with an identification mark based on the setting position of the beam plate 323. In addition, the propulsion cylinder 21 is also marked with an identification mark at the installation position of the transfer plate 229. Then, when it is necessary to adjust the limit adjustment member 22 to adapt the diameter of the pipe, it is necessary to align the identification marks on the propulsion cylinder 21 and the rust cleaning cylinder 31, that is, the transfer plate 229 and the beam plate 323 are connected through the notch 333. When adjusting the limit adjustment member 22, the adjustment distance can be synchronized to the beam plate 323 through the transfer plate 229. The transfer plate 229 It is only installed in the limit adjustment member 22, and its top surface is horizontal to the installation surface of the limit arm 224. In order not to synchronously drive the pusher 2 during the manual rotation of the rust cleaning cylinder 31, based on this consideration, the synchronization ring 332 is further arranged in this scheme, that is, the end of the synchronization ring 332 opposite to the armature plate 331 is provided with three concentrically opened convex rings 334, and the opening spacing of the three convex rings 334 is equal to the length difference between the first movement position 225, the second movement position 226 and the third movement position 227. The opening width of the convex ring 334 is adapted to the width of the transmission plate 229, and the armature plate 331 is provided with a ring groove 335 adapted to the width of the convex ring 334.When the diameter of the pipe is adapted to the first movement position 225 of the telescopic arm, the transfer plate 229 adjusts the restraining plate 323 along with the movement of the sleeve 223, and the restraining plate 323 drives the brush 322 fixedly connected thereto to move, that is, the working surface of the brush 322 contacts the surface of the pipe. After the adjustment is completed, the rust cleaning cylinder 31 is driven by manual screwing or with the help of an existing external structure combination, and the rotating plate drives several restraining plates 323 to move along the convex ring 334, so that the brush 322 removes rust from the pipe in the circumferential direction.
