Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical auxiliary equipment, specifically relates to a mechanical vibration device for epoxy powder rolling operation of steel pipe inner wall. BACKGROUND

[0002] In the process of epoxy anticorrosion treatment on the inner wall of the steel pipe, the uniformity and adhesion of the epoxy powder coating are the key factors determining the final anticorrosion quality. Generally, the epoxy powder is applied to the inner wall of the preheated steel pipe by rolling or spraying. However, due to the uneven distribution of the temperature of the steel pipe itself or the unevenness in the powder spraying process, the epoxy powder in some areas often fails to melt, flow and adhere well, resulting in uneven coating thickness, even defects such as missing points or poor adhesion, which seriously affects the anticorrosion performance and service life of the steel pipe.

[0003] In order to improve the adhesion uniformity of the epoxy powder, the operator often uses a hammer or other tools to continuously knock and vibrate the pipe head or pipe wall of the steel pipe during the rotating coating process in the traditional process. Although this method can promote the flow and uniform distribution of the powder to some extent, it has significant drawbacks: first, the operating environment is poor, the temperature of the steel pipe is usually as high as 175℃ or above, and the worker is at risk of being scalded by close operation; second, the steel pipe rotates at high speed on the rotating table, manual knocking not only has high labor intensity, but also is prone to safety accidents such as collision of the knocking tool with the rotating steel pipe and hand slipping, and has great safety hazards; third, the force and frequency of manual knocking are difficult to control accurately, the effect is unstable, and the steel pipe itself may be damaged.

[0004] Therefore, it is urgent to develop a mechanical vibration device to replace manual knocking to effectively solve the problem of uneven adhesion of the epoxy powder, improve the coating quality, and reduce the safety hazards caused by manual operation. SUMMARY

Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0030] In order to solve the problem of uneven epoxy powder bonding in the prior art, improve the quality and performance of the anticorrosive coating, and eliminate the safety hazards of manual operation in the traditional process. The mechanical vibrating device for epoxy powder rolling coating operation of the inner wall of a steel pipe provided by the utility model utilizes the combined structure of a stand 1, a vibrating rod 4, a vibrating block 5 and a cylinder 3, the stand 1, the vibrating rod 4 and the vibrating block 5 are all made of profile steel, low cost and stable structure, the actuator is the cylinder 3, with buffering, avoiding impact on the high-speed rotating steel pipe, ensuring smooth and safe vibrating process.

[0031] In a specific embodiment, as shown in Figs. 1-2 The mechanical vibrating device for epoxy powder rolling coating operation of the inner wall of a steel pipe provided by the utility model comprises a stand 1, a telescopic cylinder, a vibrating rod 4 and a vibrating block 5; wherein the stand 1 is used for supporting the device main body, the stand 1 can be made of profile steel, ensuring stable structure, one end of the telescopic cylinder is installed on the stand 1, the vibrating rod 4 is a cantilever structure, the installation end of the vibrating rod 4 is rotatably connected with the stand 1, the other end of the telescopic cylinder is drivingly connected with the vibrating rod 4, and the vibrating rod 4 reciprocates on the vertical plane under the action of the telescopic cylinder; the telescopic cylinder is used for providing power to drive the vibrating rod 4 and the vibrating block 5 to vibrate at high frequency; the vibrating rod 4 is used for transmitting the power of the telescopic cylinder to the vibrating block 5, the vibrating block 5 is installed on the free end of the vibrating rod 4, and the vibrating block 5 reciprocates on the vertical plane with the vibrating rod 4 to contact and vibrate the outer wall of the steel pipe.

[0032] In the use process, the vibrating block 5 is used for directly contacting the outer wall of the steel pipe, and the epoxy powder is uniformly bonded through vibration. In theory, the vibrating block 5 can adopt different shapes, such as square, circular, oval and the like, and can also adopt different materials, such as rubber and polyurethane, to adapt to different shapes of the outer wall of the steel pipe and coating requirements, for example, the vibrating block 5 made of rubber has good elasticity and small impact force on the outer wall of the steel pipe, and is suitable for the steel pipe with high surface requirements; the length and shape of the vibrating rod 4 can also be adjusted according to the size of the steel pipe and the rolling coating process requirements, for example, vibrating rods 4 with different lengths are used to adapt to steel pipes with different diameters.

[0033] In use, the column 1 is fixed at a designated work station, a steel pipe that needs to be subjected to inner wall epoxy powder rolling coating work is transferred to the work station turntable, the telescopic cylinder is started, the telescopic cylinder repeatedly extends and retracts, drives the vibration rod 4 to swing, and transmits the vibration force to the vibration block 5, the outer wall of the steel pipe is mechanically vibrated by the vibration block 5, and the epoxy powder is uniformly distributed on the inner wall of the steel pipe, so that the coating thickness is uniform. In this way, during the coating process, the mechanical vibration effectively promotes the uniform flow and distribution of the epoxy powder on the inner wall of the steel pipe, eliminates the problem of uneven coating thickness caused by uneven temperature or uneven coating, ensures the uniformity of the coating thickness, and significantly improves the corrosion resistance and durability of the inner wall of the steel pipe. The mechanical device replaces the dangerous manual work in a high-temperature and high-speed rotating environment, eliminates the safety risks such as scalding and mechanical injury, improves the coating quality, and reduces the safety hazards caused by manual work.

[0034] The telescopic cylinder can be a gas cylinder 3, which provides power to drive the vibration rod 4 and the vibration block 5 to vibrate at high frequency. The gas cylinder 3 has simple structure, low cost, easy to control action frequency and maintenance, and can quickly realize telescopic action, provide stable high-frequency driving force for the vibration rod 4, ensure the uniformity of vibration frequency and intensity, and ensure the uniform distribution of epoxy powder on the inner wall of the steel pipe. In theory, the telescopic cylinder is not limited to the form of the gas cylinder 3, and it can also use a hydraulic cylinder or an electric telescopic cylinder.

[0035] Further, the mechanical vibration device further comprises a rotating shaft 6 rotatably mounted to the top end of the column 1 in the horizontal direction, the mounting end of the vibration rod 4 is fixedly connected with the rotating shaft 6, and the vibration rod 4 is rotatably connected with the column 1 through the rotating shaft 6. By setting the rotating shaft 6, the vibration rod 4 can swing flexibly around the rotating shaft 6 in the vertical plane, improving the motion stability and flexibility of the vibration rod 4, ensuring that the vibration block 5 can accurately contact the outer wall of the steel pipe, and realizing uniform vibration effect. It should be understood that, in addition to the rotating shaft 6, the vibration rod 4 and the column 1 can also adopt other forms of rotary connection structure, such as universal joint connection, which can allow the vibration rod 4 to rotate freely in multiple directions, further improving the motion flexibility of the vibration rod 4, and being suitable for complex shape or irregular arrangement of steel pipe vibration work; ball hinge connection can also be used, which has high carrying capacity and motion flexibility, and can better adapt to the vibration demand under different working conditions.

[0036] When the beating rod 4 is connected with the stand 1 through the rotating shaft 6, the rotating shaft 6 can be installed on the stand 1 by using a bearing seat 7, specifically, the bearing seat 7 is fixed on the stand 1, the rotating shaft 6 is installed in the bearing seat 7, and the bearing seat 7 is used to support the rotating shaft 6, reduce friction, and prolong the service life of the device. In this way, the bearing seat 7 provides stable support and positioning for the rotating shaft 6, reduces the wear of the rotating shaft 6, prolongs the service life of the rotating shaft 6, improves the reliability and stability of the entire device, and ensures that the beating rod 4 can stably reciprocate for a long time.

[0037] A nut can also be provided between the rotating shaft 6 and the beating rod 4, in which case the rotating shaft 6 is supported by the bearing seat 7, and the connection between the rotating shaft 6 and the beating rod 4 is fixed by using a nut, to ensure that there is no displacement deviation during rotation. Other fasteners such as a snap ring or a pin can also be used between the rotating shaft 6 and the beating rod 4. The snap ring is fixed by being clamped between the rotating shaft 6 and the beating rod 4, and has a simple structure and is easy to install. The pin is fixed by being inserted through pin holes on the rotating shaft 6 and the beating rod 4, and has high fixing strength and stability, and is suitable for occasions with high connection strength requirements.

[0038] In order to improve the installation stability between the cylinder 3 and the stand 1, the mechanical beating device further comprises a cylinder base 2, and the cylinder barrel of the cylinder 3 is fixed on the stand 1 through the cylinder base 2.

[0039] In some embodiments, the cylinder rod of the cylinder 3 is connected with the beating rod 4 through a hinge. The hinge connection allows the cylinder rod of the cylinder 3 and the beating rod 4 to freely rotate within a certain angle range, which can effectively absorb and buffer the impact force and reaction force generated during beating, protecting the cylinder rod of the cylinder 3 and the beating rod 4 from damage, while ensuring that the beating rod 4 can reciprocate according to the predetermined trajectory, improving the service life and operation stability of the device. In this way, the stand 1 and the cylinder base 2, the cylinder 3 and the beating rod 4 can all be connected through a hinge, ensuring stable connection and achieving power transmission.

It should be understood that the above structures are not limited to steel profiles, and other high-strength materials such as aluminum alloy or high-strength composite materials can also be used instead of steel profiles.
