Description

Technical Field

[0001] This invention relates to the field of sandblasting equipment technology, specifically to a steel pipe sandblasting device and method. Background Technology

[0002] By sandblasting the inner and outer surfaces of steel pipes, small defects, loose rust, grease, etc. can be removed to obtain the required cleanliness and roughness, thereby improving the anchoring strength of the anti-corrosion layer. On the other hand, the impact grinding of the abrasive can improve the surface strength of the product and enhance its fatigue resistance.

[0003] The prior art patent document CN116587177A discloses a sandblasting device and its usage method for surface treatment of steel pipes. The device includes a sandblasting machine body and a sandblasting head disposed at the top of the sandblasting machine body. A collection hopper is located at the bottom of the sandblasting machine body. This sandblasting device and its usage method for surface treatment of steel pipes utilizes a controller at one end of the sandblasting machine. A fixed seat located at a telescopic column on one side of the controller can be inserted into the interior of the steel pipe body. Multiple sets of rubber plates at the fixed seat abut against the inner wall of the steel pipe body, ensuring a stable connection. This facilitates the controller's subsequent driving of a rotating disc to rotate the telescopic column, precisely rotating the unprocessed portion of the steel pipe body to the position corresponding to the sandblasting head.

[0004] Although the device has many beneficial effects, the following problems still exist: When the fixing seat on the controller side of the device is inserted into the steel pipe body, the direction of the steel pipe body needs to be aligned with the fixing seat in order for the fixing seat to be properly inserted into the steel pipe body.

[0005] Secondly, the device's mounting base is inserted into the steel pipe body, requiring the use of an electric telescopic rod to press the rubber plate against the inner wall of the steel pipe body. However, the extension and retraction of the electric telescopic rod is difficult to control, which can cause compression to the inner wall of the steel pipe body and damage it. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] 1. Technical problems to be solved:

[0008] To solve the problem mentioned above, when the fixing seat on the controller side of the device is inserted into the steel pipe body, the direction of the steel pipe body needs to be aligned with the fixing seat so that the fixing seat can be properly inserted into the steel pipe body;

[0009] Secondly, the device's mounting base is inserted into the steel pipe body, requiring the use of an electric telescopic rod to press the rubber plate against the inner wall of the steel pipe body. However, the extension and retraction of the electric telescopic rod is difficult to control, which can cause compression to the inner wall of the steel pipe body and damage the steel pipe body. Therefore, this invention was proposed.

[0184] Combination Figures 1-10 The specific usage process of the steel pipe sandblasting device and method of this embodiment is as follows:

[0185] 1: According to the actual use, the steel pipe is placed between the driving wheel a103 and the driven wheel a102. The motor a105 drives the drive shaft a104 to move the steel pipe towards the conveying unit 2. The steel pipe is squeezed by the support plate a101 and concentrated in the middle section of the feeding unit 1. The steel pipe is squeezed by the driving wheel a103 and the driven wheel a102. When it reaches the conveying unit 2, the direction of the steel pipe is flush with the clamping end of the clamping unit 3.

[0186] 2: After the motor c207 is turned off and the electromagnet rod 206 is de-energized, the magnetic connection with the magnetic rod 210 is broken. The magnetic rod 210 slides out of the slide groove 209, and the damping spring shock absorber 213 is stretched, which drives the friction plate 211 to press against the inner wall of the steel pipe.

[0187] 3: After starting the motor b204, the rotating plate 202 rotates, the electric push rod 203 rotates, and the clamping rod 205 rotates, causing the steel pipe to rotate due to the pressure of the friction plate 211.

[0188] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
