Spraying equipment for large pipe inner side

Abstract

The invention discloses spraying equipment for large pipe inner side. The spraying equipment comprises a base A, wherein a support column is mounted on the top of the base A, and a transmission bin ismounted on the top of the support column; a driving motor is mounted on one side of the transmission bin, and an output end of the driving motor extends into the inner side of the transmission bin; agear is mounted on the output end of the driving motor; a support arm in sliding connection with the transmission bin is arranged on the inner side of the transmission bin; and the top of the supportarm is uniformly provided with tooth grooves. According to the equipment, a connecting plate and a stepping motor B are mounted on the equipment, a pipe is controlled to continuously rotate at a constant speed in the spraying process, automatic spraying is achieved, the spraying efficiency and effect are improved, the manual requirement is reduced, and the gap between two groups of mounting plates is adjusted by adjusting the position relation of a fastening bolt and a threaded hole, so that the equipment is suitable for pipes with different lengths, and the applicability of the equipment isfurther improved.

Description

technical field [0001] The invention relates to the technical field of pipe processing equipment, in particular to a large pipe inner spraying equipment. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipes use different pipes. The quality of pipes directly determines the quality and service life of pipes. With the development of society, a large number of pipes are used in construction projects, power plants, and chemical plants. And other fields, and the pipe needs to go through multiple processing procedures before it can reach the use standard, and spraying paint, corrosion-resistant paint and other liquid agents greatly affect the service life of the pipe. [0003] The existing spraying method is generally that the operator sprays with a hand-held spraying equipment, and the spraying distance, angle, thickness and other values ​​cannot be fixed, resulting in low spraying efficiency, uneven spraying, affecting the quality and ser...

Problems solved by technology

[0002] Pipe is the material used to make pipe fittings. Different pipes use different pipes. The quality of pipes directly determines the quality and service life of pipes. With the development of society, a large number of pipes are used in construction projects, power plants, and chemical plants. And many other fields, and the pipe needs to go through multiple processing procedures before it can reach the use standard, and spraying paint, corrosion-resistant paint and other liquid agents greatly affect the service life of the pipe

[0003] The existing spraying method is generally that the operator sprays with a hand-held spraying equipment, and the spraying distance, angle, thickness and other values ​​cannot be fixed, resulting in low spraying efficiency, uneven spraying, affecting the quality and service life of the pipe, and the workload is high. Large, it is easy to cause fatigue of the operators. During the spraying process, due to the need for manual construction, the spraying liquid is easily inhaled into the lungs of the operators, causing harm to the health of the operators. Therefore, the present invention designs a large-scale pipe inner spraying equipment To solve the problems existing in the prior art
