Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel pipe coating operation, especially a steel pipe blanking device. BACKGROUND

[0002] In the use process, especially in the humid, strong corrosive environment, steel pipes are easily damaged by oxidation and corrosion, resulting in a decrease in strength and a shortening of service life. By coating a layer of corrosion-resistant material on the surface of the steel pipe, direct contact between the steel pipe and the environment can be effectively prevented, thereby preventing or slowing down the corrosion process and prolonging the service life of the steel pipe.

[0031] In the embodiment, after the surface of the steel pipe is coated, the steel pipe is placed horizontally, the rack 22 is driven by the first driver 25 to move towards the fastening mechanism 1, and the sleeve 12 is clamped and fixed by the plurality of clamping assemblies 23, then the movable part 112 is pushed by the pushing assembly to move relative to the fixed part 111, so that the fastening assembly 11 changes from the fixed state to the movable state relative to the steel pipe, finally, the rack 22 is driven by the first driver 25 to move away from the steel pipe, so that the fastening mechanism 1 is separated from the steel pipe, thereby realizing the dismounting of the fastening mechanism 1 from the steel pipe for subsequent work.

[0032] In the embodiment, the dismounting of the fastening mechanism 1 from the steel pipe can be realized by using the feeding mechanism 2 instead of manual operation, which can reduce the labor intensity of workers, improve work efficiency, avoid the harm of chemical substances on the surface of the steel pipe to workers, reduce the harm of the working environment to workers, and ensure the life and health of workers.

[0033] In the embodiment, the plurality of clamping assemblies 23 form a containing space for containing the sleeve 12, the clamping assembly 23 comprises a clamping piece 231 and a second driver 232, the second driver 232 is used to drive the clamping piece 231 to move towards or away from the sleeve 12, when the second driver 232 works, the clamping piece 231 can be driven to move towards the sleeve 12, so that the clamping piece 231 is in close contact with the sleeve 12, and the sleeve 12 is clamped and fixed. The second driver 232 can be a cylinder extension structure. In addition, the side of the clamping piece 231 close to the sleeve 12 has a clamping surface, and the clamping surface has an anti-skid structure, which can be a plurality of anti-skid grooves formed on the clamping surface. The anti-skid structure can increase the roughness of the clamping surface, thereby increasing the friction when the clamping surface contacts the outer surface of the sleeve 12, and improving the stability of clamping.

[0034] In the embodiment, the plurality of clamping assemblies 23 are uniformly and spacedly arranged along the circumference of the sleeve 12, so as to stably clamp the sleeve 12. The number of the clamping assemblies 23 is three, and one of the clamping assemblies 23 is arranged directly below the sleeve 12, which helps to improve the stability of clamping the sleeve 12 by the clamping assembly 23.

[0035] In the embodiment, two slide rails 26 are arranged on the base 21, and the slide rails 26 are arranged on two sides of the base 21 and extend along the axis of the steel pipe. At least one sliding piece 27 is arranged on the rack 22 corresponding to each slide rail 26, and the sliding piece 27 is slidably connected to the slide rail 26. The sliding piece 27 is connected to the bottom of the rack 22. In addition, it should be noted that the first driver 25 is a screw rod motor structure, in which the motor is positioned on the base 21, and the screw rod is connected to the rack 22 through a nut sleeve. When the motor works, it can drive the screw rod to move linearly, thereby driving the rack 22 to slide on the base 21.

[0036] In the embodiment, the pushing assembly 24 includes at least one driving telescopic rod 242 and a pushing piece 241. The driving telescopic rod 242 is arranged on the rack 22, and the pushing piece 241 is arranged on the side of the movable part 112 away from the steel pipe. The telescopic end of the driving telescopic rod 242 is connected to the pushing piece 241. The driving telescopic rod 242 is used to drive the pushing piece 241 to move linearly along the axis of the steel pipe. When working, the pushing piece 241 is moved by the driving telescopic rod 242, so that the pushing piece 241 contacts and pushes the movable part 112 to move. The driving telescopic rod 242 can be a telescopic pneumatic cylinder or an electric telescopic rod.

[0037] In the embodiment, the vertical sectional area of the fastening assembly 11 gradually decreases towards the steel pipe, the vertical sectional area of the movable part 112 gradually increases towards the steel pipe, the outer surface shape of the fastening assembly 11 matches the shape of the inner wall of the steel pipe, and when the fastening assembly 11 gradually inserts into the inner wall of the steel pipe, the friction between them gradually increases. Under the action of an external force, when the outer diameter of the fastening assembly 11 entering the steel pipe is slightly larger than the inner diameter of the steel pipe, the inner wall of the steel pipe can be in close contact with the fastening assembly 11, and there is a large static friction between them, thereby realizing the fixation of the two. When the movable part 112 moves into the steel pipe under the pushing of the pushing assembly 24, the vertical sectional area of the movable part 112 gradually increases towards the steel pipe, and the contact area between the fastening assembly 11 and the inner wall of the steel pipe decreases, so that the fastening assembly 11 is loosened relative to the steel pipe. Therefore, under the driving of the rack 22, the fastening assembly 11 can be moved out of the steel pipe.

[0038] In the embodiment, in order to improve the friction when the fastening assembly 11 contacts the inner wall of the steel pipe, the surface of the fixed part 111 for contacting the inner wall of the steel pipe is provided with anti-skid grooves.

[0039] In the embodiment, in order to avoid the moving part 112 from the sleeve 12 on the side away from the steel pipe, the sleeve 12 is provided with a first blocking piece 13 for preventing the moving part 112 from being separated from the sleeve 12 in the direction away from the steel pipe, and the moving part 112 is provided with a second blocking piece 14, the first blocking piece 13 can abut against the second blocking piece 14, thereby blocking the moving part 112 from being separated from the sleeve 12. The first blocking piece 13 and the second blocking piece 14 are both annular.
