Problems solved by technology

[0002] At present, pipelines are widely used in various fields, and the inner walls of many pipelines need to be sprayed. At present, most of the related operations are still done manually, and the equipment for spraying is not very mature.
CN204448347U discloses a pipeline inner wall spraying device, which enters the inside of the pipeline through three bidirectional walking trolleys connected in sequence to perform operations, which alleviates the fatigue of manual operation to a certain extent, but the device is not suitable for large Batch and high-speed industrial applications make it difficult to achieve high-efficiency spraying operations
At the same time, it is difficult to carry out secondary reinforcement of the coating, and its degree of automation is not very good
[0003] In a word, the prior art products cannot well solve the problem of pipeline inner wall spraying

Embodiment 1

[0030] according to the above figure 2 , image 3 ,and Figure 4 As shown, a robot for spraying the inner wall of a pipeline is produced, in which there are 3 lifting and rotating mechanisms, 48 ​​wedge-shaped pads in total, the wedge angle of the wedge-shaped pads is 30°, 48 supports, and 24 electric rollers B. The setting method of the electric roller B is sequentially cross-symmetrical. The operation control program of the PLC is: start the equipment → start → detect whether the pipeline to be sprayed is placed in the station, if no, alarm; if yes, start the high-speed conveying pipeline → detect whether the nozzle enters Pipeline, no, continue high-speed conveying, low-speed conveying → turn on the nozzle to start spraying operation → check whether the spraying operation is completed → no, continue spraying operation; yes, lift the rotating mechanism to rise → detect whether the lifting and rotating mechanism is in contact with the outer wall of the pipeline → no, contin...

Abstract

The invention relates to a pipeline inner wall spraying robot, which relates to a pipeline inner wall spraying device, which can automatically complete the pipeline inner wall spraying operation, and can perform secondary reinforcement of the coating, and can well adapt to industrialized large-batch continuous operation. Including frame, lifting and rotating mechanism, spraying mechanism, pipeline, conveying mechanism, and control system; the frame is made of square pipe welding; Seat, electric roller A, joint, lifting and rotating mechanism are located in the middle of the frame as a whole; the spraying mechanism includes the spray head pole and spray head, and the spraying mechanism is located in the upper left side of the frame as a whole; the conveying mechanism includes wedge-shaped pads and supports , Electric roller B, the conveying mechanism is located on the upper layer of the frame as a whole; the pipeline is located on the upper layer of the frame and supported by the electric roller B; the control system is mainly completed by PLC.

Description

technical field [0001] The technical solution of the invention relates to a device for spraying the inner wall of a pipeline, in particular to a robot for spraying the inner wall of a pipeline. Background technique [0002] At present, pipelines are widely used in various fields, and the inner walls of many pipelines need to be sprayed. At present, most of the related operations are still done manually, and the equipment for spraying is not very mature. CN204448347U discloses a pipeline inner wall spraying device, which enters the inside of the pipeline through three bidirectional walking trolleys connected in sequence to perform operations, which alleviates the fatigue of manual operation to a certain extent, but the device is not suitable for large Batch and high-speed industrial applications make it difficult to achieve high-efficiency spraying operations. At the same time, it is difficult to carry out secondary reinforcement of the coating, and its degree of automation ...
