Description

Technical Field

[0001] The utility model relates to the technical field of rust removal equipment, in particular to an equipment for rust removal on the surface of steel structures. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. This structure is mainly composed of components such as steel beams, steel columns, and steel trusses made of materials such as sections and steel plates. After several years of use of the steel structure, due to the peeling of the paint on the outer surface and the erosion by rainwater or water molecules in the air, a large area of rust will appear on the surface of the steel structure, and rust removal treatment needs to be carried out on the steel structure.

[0003] The traditional method for rust removal on the surface of steel structures is mostly that workers hold sandpaper or polishing machines to polish and remove rust on the outer wall of the steel structure. During the rust removal process, a large amount of flying dust will be generated. After workers inhale the flying dust, it will affect the health of workers. At the same time, the falling rust splashes everywhere and is not easy to clean, and may remain on the workbench or other equipment, increasing the risk of rust on the workbench or other equipment.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The device for rust removal on the surface of steel structures realizes automated and enclosed rust removal operations through the integrated housing, support base, rust removal mechanism, and collection mechanism. The chamber inside the housing provides a sealed space, enabling effective control of the flying dust generated during the rust removal process, reducing the harm to workers' health. The rust removal mechanism utilizes the cooperation of the moving part, screw rod, rust removal plate, and driving motor A to achieve the reciprocating scraping of the rust removal plate on the steel structure, improving the rust removal efficiency. The collection mechanism consists of a diversion structure and through holes, which can effectively collect and centrally process the rust and flying dust generated during the rust removal process, reducing the cleaning difficulty and the risk of corrosion. In addition, the device is provided with a feeding port and an installation structure, facilitating the placement and stability of the steel structure and ensuring the smooth progress of the rust removal operation.

[0018] 2. It further includes a collection cylinder, which is installed in the through hole. The collection cylinder is directly installed in the through hole for collecting rust, which is more convenient.

[0019] 3. By arranging the first section chamber, the second section chamber, and the step in the through hole, and cooperating with the compression spring, avoidance notch, clamping block, and clamping groove, the collection cylinder can be both tightly connected to the housing and easily disassembled for cleaning. This structural design enhances the practicability and maintenance convenience of the device.

[0020] 4. The inner wall of the first section chamber is designed in a conical shape, and the inner diameter of the first section chamber decreases sequentially from top to bottom, which is beneficial to accelerating the sliding of rust and flying dust down to the collection cylinder, reducing their accumulation at the bottom of the chamber, further improving the collection efficiency, reducing the cleaning difficulty, and at the same time helping to reduce the pollution to other components of the device.

[0021] 5. The installation structure includes a fixed cylinder, a driving motor B, and a clamping device. The fixed connection between the fixed cylinder and the driving motor B ensures the effective transmission of power. The clamping device is used to limit and fix the steel structure to ensure that the steel structure remains stable during the rust removal process, avoiding affecting the rust removal effect or damaging the device due to shaking. The other end of the steel structure is placed in the feeding port, and the rotation axis of the steel structure is parallel to the arrangement direction of the screw rod, enabling all-round rust removal of the steel structure. This design ensures the efficient and safe progress of the rust removal operation.

[0022] 6. The diversion structure is a diversion plate, and the upper surface of the diversion plate is inclined relative to the horizontal plane. The inclined low end of the upper surface of the diversion plate corresponds to the through hole. Such a design forms an efficient diversion path to ensure that the rust and flying dust can quickly and completely slide into the collection cylinder.

[0023] 7. The deflector adopts a combined structure of a first inclined plate, a connecting plate and a second inclined plate, forming an efficient guiding path to ensure that rust and flying dust can quickly and completely slide into the collection cylinder. The parts are closely fitted together, reducing the possibility of flying dust escaping and further improving the dust removal effect of the equipment. The lower inclined ends of the first inclined plate, the connecting plate and the second inclined plate form a U-shaped area, which corresponds to the through hole, ensuring that the rust falling from above is collected in the U-shaped area through the first inclined plate, the connecting plate and the second inclined plate and then slides into the collection cylinder. This design not only takes into account the generation law of rust and flying dust during the rust removal process, but also gives consideration to the effective utilization of the internal space of the equipment, improving the overall performance of the equipment.

[0024] 8. A visual window is opened on the front or rear side of the housing, enabling the operator to directly monitor the rust removal process inside the equipment, promptly discover and handle abnormal situations, and ensure the smooth progress of the rust removal operation. The design of the visual window enhances the operation convenience and safety of the equipment.

[0025] 9. A belt is used to connect the output end of the driving motor A and the screw. Compared with direct rigid connection, belt drive has good buffering and vibration absorption capabilities, can reduce the operating noise of the equipment, reduce the wear of transmission parts, and extend the service life of the equipment. At the same time, belt drive allows for a certain installation error between the motor and the screw, simplifying the equipment assembly and maintenance.

[0026] 10. A first limit block and a second limit block are respectively arranged at the output end of the driving motor A and the connection end of the screw, which can effectively prevent the belt from shifting or disengaging during operation, ensuring the stability and reliability of the transmission. This design enhances the safety performance of the equipment, avoids equipment shutdown or damage caused by transmission failures, and is beneficial to improving the continuous working ability and overall working efficiency of the equipment.
