Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to an automatic rust removal device for sleeves. Background Technology

[0002] In concrete structure construction, steel embedded sleeves are key components for pipelines penetrating the structure. However, in humid environments or during long construction periods, the inner walls of these sleeves embedded in the floor slab during the early stages of construction may corrode, directly affecting the quality of subsequent pipeline installation. Currently, the industry practice is to manually remove rust using a wire brush. This method is inefficient, and workers cannot guarantee full circumferential rust removal, resulting in missed areas and making it difficult to control the quality of standardized operations. Furthermore, manual rust removal poses safety risks; rotating the wire brush can easily cause hand injuries. Utility Model Content

[0022] 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 scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] Reference Figures 1-4 This utility model provides an automatic rust removal device for sleeves, including a bracket 1 and a rust remover. The bracket 1 is equipped with a slide rail 2. The rust remover includes a motor 3, a rotary transmission shaft 4, and a brush head assembly. The brush head assembly is connected to the output shaft of the motor 3 via the rotary transmission shaft 4. The motor 3 is slidably mounted on the slide rail 2, and the rotary transmission shaft 4 is parallel to the length direction of the slide rail 2. Before use, select a suitable brush head assembly according to the pipe diameter. Run the device under no-load to check the vibration frequency and noise of the motor 3. Check the stability of the device by running it at different speeds. After confirming that everything is correct, adjust the bracket 1 so that the rust remover is aligned with the center of the sleeve and lock the bracket 1. Move the rust remover along the slide rail 2 so that the brush head assembly extends vertically into the sleeve. Start the motor 3; the brush head assembly rotates under the drive of the rotary transmission shaft 4, wiping away the rust on the inner wall of the sleeve. The motor 3 can be adjusted to set a dual-mode composite cutting (coarse grinding + fine polishing) to improve the cleaning quality. The bracket 1 can be a steel frame with a base to ensure the stability of the motor 3 during operation. The length of slide rail 2 is designed according to actual needs to ensure that the rust remover can clean the entire inner wall of the sleeve. Preferably, the length of slide rail 2 is parallel to the length of the sleeve for stable guidance and to prevent axial scratches caused by brush head assembly misalignment. A small motor 3 is generally sufficient to provide enough torque to meet the cutting force required by the rust removal brush.

[0025] Furthermore, the brush head assembly includes a brush roller 5 and a plurality of brush heads 6 arranged circumferentially on the brush roller 5; the brush roller 5 is detachably mounted on one end of the rotary drive shaft 4. When the rotary drive shaft 4 drives the brush roller 5 to rotate, the brush heads 6 on its surface remove rust from the inner wall of the sleeve. The number and specific distribution of the brush heads 6 are designed according to actual needs. The diameter of the brush roller 5 matches the diameter of the sleeve to be cleaned, and the automatic rust removal device for the sleeve can be configured with multiple brush rollers 5 of different sizes to handle different sleeves in concrete structure construction. The brush roller 5 can be made from a sleeve with a diameter smaller than that of the sleeve to be cleaned, and brush heads 6 are installed on its outer circumferential surface to form a brush head assembly. Preferably, as Figure 4 As shown, the brush head 6 and the brush roller 5 are connected by an adjustable screw 13. By turning the screw 13, the distance between the two can be adjusted so that the brush head 6 fits against the inner wall of the sleeve to be cleaned for rust removal.

[0026] Specifically, the brush head 6 is provided with bristles, preferably polyester fiber bristles and silicon carbide bristles. More preferably, the surface of the brush head 6 is circular, with multiple rings of polyester fiber bristles and / or silicon carbide bristles arranged from the inside to the outside. The use of polyester fiber + silicon carbide composite bristles can ensure that the rust removal efficiency matches the rust on the pipe wall surface.

[0027] To better control the rust removal effect inside the sleeve, the automatic rust removal device for the sleeve also includes a drive assembly for driving the rust remover to slide on the slide rail 2. The drive assembly can be a cylinder or other device that can drive the rust remover to move on the slide rail 2. By adjusting the relative position of the brush head assembly and the slide rail 2 through the drive assembly, the brush head assembly can be inserted into different positions inside the sleeve to clean the inner wall in all directions.

[0028] In a detailed embodiment, the driving component includes a self-locking screw 7; the rust remover is provided with a self-locking nut 9 that matches the self-locking screw 7; the self-locking nut 9 is threadedly connected to the self-locking screw 7; the self-locking screw 7 is rotatably mounted on the bracket 1. Specifically, the bracket 1 has a threaded hole, and one end of the self-locking screw 7 is inserted into the threaded hole of the bracket 1 and passes through the self-locking nut 9 to connect with the rust remover. During operation, rotating the self-locking screw 7, in conjunction with the self-locking nut 9, vertically pushes the rust remover to move up and down, thereby achieving a thorough cleaning of the inner wall of the sleeve.

[0029] Preferably, a turntable 8 is provided at one end of the self-locking screw 7. The turntable 8 is generally located at the upper end, which facilitates manual rotation of the self-locking screw 7, so that the self-locking device pushes the rust remover to move vertically downward along the slide rail 2 at a slow and uniform speed, while preventing the self-locking screw 7 from falling off the bracket 1.

[0030] Furthermore, the bottom of the bracket 1 is equipped with rollers 11, preferably omnidirectional wheels, to facilitate moving the automatic rust removal device of the sleeve to different positions of the sleeve.

[0031] Preferably, the bracket 1 is equipped with a bracket fixing component for fixing the bracket 1 to the concrete structure or other working surface near the sleeve. When the bracket 1 is equipped with casters at the bottom, a locking device such as a brake pad or locking pin can be provided to ensure that the bracket 1 can be stably fixed when needed.

[0032] In a more detailed embodiment, the automatic rust removal device for sleeves further includes a mounting base 10; the mounting base 10 is slidably mounted on the slide rail 2; the motor 3 is fixed on the mounting base 10 and drives the rust remover to move up and down along the slide rail 2 via the mounting base 10. When using the mounting base 10, it is preferable to set two parallel slide rails 2 on the bracket 1, with the mounting base 10 installed between the two slide rails 2, which ensures smooth operation on the one hand, and provides lateral limitation for the mounting base 10 on the other hand.

[0033] To prevent the rust remover from moving beyond its range, both ends of the slide rail 2 are equipped with movement limiting components 12 to prevent the rust remover from derailing. Specifically, a screw is inserted laterally at each of the upper and lower ends of the slide rail 2 as a movement limiting component 12 to limit the movement of the rust remover or the mounting base 10.

[0034] Furthermore, since the light inside the sleeve is weak, it is easy to miss details when judging whether rust removal is complete by visual inspection. Therefore, the rust remover also includes a camera that transmits real-time images of the inside of the sleeve to determine completion. The camera can be mounted on the brush head assembly, rotating to collect images of the inner wall of the sleeve and transmitting them to a corresponding image receiving device. The operator or image recognition equipment then determines whether rust removal is complete based on the captured images. Optionally, the automatic rust removal device for the sleeve also includes a PLC control system. The PLC control system is electrically connected to the image recognition device and motor 3, respectively, and controls the start and stop of motor 3 based on the feedback from the image recognition device.

[0035] In an optimized embodiment, to prevent rust scraped off by the rust remover from accumulating inside the sleeve, the automatic rust removal device for the sleeve also includes a vacuum cleaner. The vacuum cleaner is slidably mounted on the slide rail 2, with its specific position designed according to actual conditions to avoid interfering with the rust remover's travel path. Optionally, both the vacuum cleaner and the dust collector are mounted on the mounting base 10, with the vacuum cleaner positioned above the brush head assembly. When the mounting base 10 moves down, allowing the brush head assembly to extend into the sleeve for rust removal, the vacuum cleaner above it starts simultaneously to absorb the rust scraped off by the brush head assembly.

[0042] After the motor 3 equipment has been tested and found to be operating normally, push the bracket 1 to the sleeve to be cleaned, adjust the bracket 1 so that the rust remover is aligned with the center of the sleeve, and fix the bracket 1 in place using the bracket fixing parts. Rotate the turntable 8 so that the self-locking screw 7 engages with the self-locking nut 9, and push the mounting base 10 to move vertically downwards along the slide rail 2 at a slow and uniform speed. Start the motor 3, and the brush roller 5 and brush head 6 rotate under the drive of the rotating transmission shaft 4 to wipe away the rust on the inner wall of the sleeve.
