Description

Technical Field

[0001] The utility model belongs to the field of steel component processing, in particular to a continuous steel component outer surface rust removal device. Background Art

[0002] In order to extend the service life and structural strength of steel structures, steel components need to be derusted before processing and producing steel structures to ensure that the material has good performance.

[0003] At present, rust removal devices for steel components are roughly divided into two categories. One type of rust removal device is a box structure as a whole, with a clamp and a sandblasting rust removal mechanism installed inside it. This type of rust removal device is limited by its own structural design and can only rust smaller steel components and cannot operate continuously. However, in actual processing, a large number of medium and large-sized steel components need to be rusted, resulting in a narrow application range of this type of rust removal device; the other type of rust removal device is similar to a production line as a whole, and the steel components move on a conveyor, and rust removal is completed when passing through the rust removal mechanism. Although this type of rust removal device is not limited by the size of the steel components, there is also a problem that the side in contact with the conveyor cannot be rusted, and multiple rust removal operations are required.

[0004] In response to the problems existing in existing rust removal devices, the applicant has proposed a continuous steel component outer surface rust removal device, thereby solving the defects existing in existing rust removal devices. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous steel component outer surface rust removal device, thereby solving the problems existing in the prior art in the background technology. To achieve this purpose, the specific technical solution is as follows:

[0006] A continuous steel component outer surface rust removal device, wherein a first conveyor and a second conveyor are arranged adjacent to each other end to end, a rust removal mechanism housing is installed between the end gaps of the first conveyor and the second conveyor, a sandblasting port is annularly installed in the rust removal mechanism housing through a sandblasting port bracket, and the sandblasting port is connected to a sandblasting unit powered by a power supply through a pipeline.

[0007] Furthermore, the sandblasting unit is composed of a sandblasting machine and an air compressor, and is powered by a power supply.

[0008] Furthermore, a number of supporting wheels are fixed on the inner wall of the rust removal mechanism housing, and a rolling ring with a wheel rail is arranged on the outer side and is installed in the rust removal mechanism housing through the cooperation of the supporting wheel and the wheel rail. A driving motor powered by a power supply is also fixed on the inner wall of the rust removal mechanism housing. Under the control of the controller, the driving motor drives the rolling ring to rotate through the driving wheel arranged on its rotating shaft and located in the wheel rail. The rolling ring is annularly installed with a sandblasting port bracket.

[0009] Furthermore, the driving motor is a reduction motor and is powered by a power supply.

[0010] Furthermore, the controller is a motor forward and reverse rotation controller, and is powered by a power supply.

[0011] Furthermore, the sandblasting port bracket is mounted on the rolling ring via fixing bolts, and adjustment holes are provided on the sandblasting port bracket. When the fixing bolts are inserted into different adjustment holes, the position of the sandblasting port can be adjusted.

[0012] The beneficial effects of the utility model are:

[0013] (1) The present application achieves rust removal on all outer surfaces of the steel components passing through at the same time by setting annularly distributed sandblasting ports between the adjacent gaps at the head and tail of two groups of conveyors.

[0014] (2) Each sandblasting nozzle of the present application can perform reciprocating circular motion under the drive of a motor, so that the relative angle between the sandblasting nozzle and the steel structure can be changed. Based on this structure, on the one hand, while ensuring complete coverage of the steel structure, the number of sandblasting nozzles is effectively reduced. On the other hand, different surfaces and degrees of rust may require different angles of spraying to achieve the best cleaning effect. The appropriate angle can enable the sand particles to hit the surface in the most effective way, thereby removing rust and old coatings more quickly.

[0015] (3) The position of each sandblasting port of the present application can be adjusted as needed, so that when the device of the present application is used to sandblast and remove rust on steel components of different specifications, each sandblasting port can be at a more appropriate distance, thereby improving the practicality of the device.

DETAILED DESCRIPTION

[0021] This embodiment provides a continuous steel component outer surface rust removal device, wherein a first conveyor 1 and a second conveyor 2 are arranged adjacent to each other end to end, a rust removal mechanism housing 3 is installed between the end gaps of the first conveyor 1 and the second conveyor 2, a sandblasting port 5 is installed in a ring in the rust removal mechanism housing 3 through a sandblasting port bracket 4, and the sandblasting port 5 is connected to a sandblasting unit 6 powered by a power supply through a pipeline.

[0022] After the steel component is placed on the first conveyor 1, it is transported toward the second conveyor 2. When it passes through the rust removal mechanism housing 3, the sand particles ejected from each sandblasting port 5 can fully impact the outer surfaces of the portion of the steel component located inside the rust removal mechanism housing 3. As the steel component moves, the rust removal of the entire steel component is completed.

[0023] Furthermore, the sandblasting unit 6 is composed of a commercially available sandblasting machine and an air compressor, and is powered by a power supply, wherein the air compressor provides an air source for the sandblasting machine.

[0024] Furthermore, in order to improve the sandblasting and rust removal effect; while ensuring that each sandblasting port 5 can simultaneously remove rust from a certain section of the outer surface of the steel structure, the number of sandblasting ports 5 is reduced, and a number of support wheels 7 are fixed on the inner wall of the rust removal mechanism shell 3, and a rolling ring 9 with a wheel rail 8 is arranged on the outer side and is installed in the rust removal mechanism shell 3 through the cooperation of the support wheel 7 and the wheel rail 8. A drive motor 10 powered by a power supply is also fixed on the inner wall of the rust removal mechanism shell 3. Under the control of the controller 11, the drive motor 10 drives the rolling ring 9 to rotate through the drive wheel 12 located in the wheel rail 8 arranged on its rotating shaft. The rolling ring 9 is annularly installed with the sandblasting port bracket 4. Each sandblasting port 5 can perform reciprocating circular motion under the action of the drive motor 10, so that while ensuring complete coverage of the steel structure, the number of sandblasting ports 5 is effectively reduced. On the other hand, the moving sandblasting port 5 changes the angle with the outer surface of the steel structure, so that the sand particles can hit the outer surface of the steel structure at different angles, thereby removing rust and old coatings faster and achieving better rust removal effect.

[0025] Furthermore, the driving motor 10 is a reduction motor and is powered by a power supply.

[0026] Furthermore, the controller 11 is a motor forward and reverse rotation controller, and is powered by a power supply.

[0027] Furthermore, in order to ensure that the sandblasting port 5 can maintain an appropriate distance from the outer surface of the steel component when the device is removing rust from steel components of different sizes, the sandblasting port bracket 4 is installed on the rolling ring 9 through a fixing bolt 13, and an adjustment hole 14 is provided on the sandblasting port bracket 4. When the fixing bolt 13 is inserted into different adjustment holes 14, the position of the sandblasting port 5 can be adjusted.

[0028] In particular, the above-mentioned electrical equipment can be powered by batteries or mains electricity.
