Description

Technical Field

[0001] This utility model relates to the field of steel pipe grinding technology, specifically a steel pipe surface grinding and sandblasting device. Background Technology

[0002] The steel pipe surface grinding and sandblasting device is a high-efficiency metal surface treatment equipment. Its main function and purpose is to clean, remove rust and dirt from the surface of the steel pipe by high-speed jetting abrasive, and increase its roughness, thereby improving the adhesion between the steel pipe and the subsequent coating, enhancing fatigue resistance, and extending the durability of the paint.

[0003] The steel pipe surface grinding and sandblasting device mainly consists of a compressor, air tank, high-pressure air pipe, spray gun, steel pipe rotating device and controller. Its working principle is to use compressed air to spray abrasive at high speed onto the surface of the steel pipe. Through the impact and cutting action of the abrasive with the surface of the steel pipe, the purpose of cleaning and rust removal is achieved. The operation process usually includes installing the steel pipe on the rotating device, setting the sandblasting parameters, starting the compressor and spray gun, and starting the sandblasting treatment.

[0004] However, in actual use, the sandblasting module and the rotating steel pipe of the above-mentioned equipment are independent of each other, and it is impossible to achieve efficient coordination between sandblasting and steel pipe movement. During sandblasting, the steel pipe cannot adjust its position in time according to the direction of sand spraying, which easily leads to sandblasting dead angles and reduces grinding efficiency and quality. In view of this, we propose a steel pipe surface grinding and sandblasting device. Utility Model Content

[0005] The purpose of this invention is to provide a steel pipe surface grinding and sandblasting device to solve the problems mentioned in the background art.

[0032] In one embodiment of this utility model, a sandblasting assembly 5 is provided on the support 2. The sandblasting assembly 5 includes a funnel 51. The funnel 51 is fixedly installed on the support 2. The sand inlet end of the sandblasting module 52 is fixedly installed at the bottom of the funnel 51. One end of the connecting pipe 53 is fixedly installed at the sand outlet end of the sandblasting module 52. The other end of the connecting pipe 53 is fixedly installed with a nozzle 54. A support trolley 55 is slidably installed on the support 2. One end of the cylinder 56 is fixedly installed on the support trolley 55. The other end of the cylinder 56 is fixedly installed with a gear cylinder 57. A motor 58 is fixedly installed inside the cylinder 56. A central gear 59 is fixedly installed at the output end of the motor 58. A cover plate 510 is rotatably installed on the gear cylinder 57. A short rod 511 is rotatably installed on the cover plate 510. One end of the short rod 511 is fixedly installed with... One end of the disc 512 is fixedly installed. A thick rod 513 is fixedly installed on the disc 512. A peripheral gear 514 is fixedly installed on the short rod 511. A steel pipe body 515 is sleeved on the thick rod 513. Multiple sets of short rod 511, disc 512, thick rod 513, peripheral gear 514 and steel pipe body 515 are arranged. A central gear 59 meshes with multiple sets of peripheral gears 514 and multiple sets mesh with gear cylinder 57. The central gear 59 and multiple sets of peripheral gears 514 are located inside the gear cylinder 57. The central gear 59 and multiple sets of peripheral gears 514 are located at the bottom of the cover plate 510. A funnel 51 is located inside the outer shell 3. A nozzle 54 is located inside the outer shell 3. The door panel module 4 consists of a support frame, a hydraulic rod, two sets of slide rails and a door panel.

[0033] In this embodiment, before using the steel pipe surface grinding and sandblasting device, the device is placed in a suitable working area. The base 1 provides stable support for the entire device, and the bracket 2 is fixed on the base 1, supporting the outer shell 3 and other components. At this time, the motor 58 and sandblasting module 52 of the sandblasting component 5 are not started, the support trolley 55 is in the initial position, the door module 4 is closed, and all components are in the initial state. After starting the device, the sand is first poured into the funnel 51 on the bracket 2. The bottom of the funnel 51 is connected to the sand inlet end of the sandblasting module 52. The sand flows into the sandblasting module 52 under the action of gravity. The sandblasting module 52 accelerates the sand through the internal pressure system and then delivers it to the nozzle 54 through the connecting pipe 53. At the same time, the motor 58 in the cylinder 56 on the support trolley 55 is started. The central gear 59 fixedly installed at the output end of the motor 58 serves as the sun gear of the planetary gear set and begins to rotate. Multiple sets of peripheral gears 514 serve as planetary gears and mesh with the central gear 59. Furthermore, the peripheral gear 514 meshes with the gear cylinder 57. This planetary gear set structure allows multiple short rods 511 to revolve within the gear cylinder 57, while simultaneously rotating on their own axis. One end of each short rod 511 is fixed to a disc 512, and a thick rod 513 is fixed to the disc 512. The steel pipe body 515 is fitted onto the thick rod 513. Therefore, the combined motion of the short rods 511 drives the steel pipe body 515 to rotate on its own axis while revolving around the center of ...

[0034] In one embodiment of this utility model, a cleaning component 6 is provided on the support trolley 55. The cleaning component 6 includes a connecting frame 61. One end of the connecting frame 61 is fixedly installed on the cover plate 510, and an mounting plate 62 is fixedly installed on the other end of the connecting frame 61. A protective cylinder 63 is fixedly installed on the mounting plate 62.

The spring 64 is located inside the protective cylinder 63, the connecting rod 65 slides inside the protective cylinder 63, and the other end of the scraper 66 is attached to the surface of the support trolley 55.

[0035] In this embodiment, during the movement of the support trolley 55 and the sandblasting of the steel pipe body 515, sand will fall onto the support trolley 55. At this time, the cleaning component 6 starts to work. Since the spring 64 is located inside the protective cylinder 63 and the connecting rod 65 slides inside the protective cylinder 63, the protective cylinder 63 protects the spring 64 and the connecting rod 65, preventing the sand from affecting their normal operation. Under the elastic action of the spring 64, the connecting rod 65 always pushes the scraper 66 to adhere to the surface of the support trolley 55. As the support trolley 55 moves, the scraper 66 promptly scrapes off the sand that falls on the support trolley 55. Multiple sets of connecting frames 61, mounting plates 62, springs 64 and scrapers 66 work together to effectively prevent sand from accumulating on the support trolley 55, affecting the sliding of the support trolley 55 and the normal operation of the equipment, extending the service life of the equipment, and maintaining a clean working environment.
