Description

Technical Field

[0002] Metal pipes are important materials in construction projects. Since the working environment when using metal pipes is relatively complex, in order to improve the service life and use effect of metal pipes, it is usually necessary to perform surface rust removal and painting on the metal pipes to make the metal pipes suitable for long-term work in different environments, thereby reducing the use and maintenance costs. However, the existing metal pipes are basically divided into two processes for rust removal and painting. After rust removal, the metal pipes are taken out and moved to the painting equipment for processing. This processing method has low work efficiency and causes many inconveniences to the rapid production of metal pipes. At the same time, the rust removal and painting equipment used are relatively complex, and the rust removal and painting effects of metal pipes are not ideal.

[0003] In the prior art, application number CN202010202945.7 discloses a rust removal and paint spraying device for metal pipes, comprising a rust removal and paint spraying body placed on the ground, the rust removal and paint spraying body being provided with a fixed rod and a first threaded rod capable of installing the rust removal and paint spraying device, a clamping device and a lifting platform being provided in the rust removal and paint spraying body, the clamping device comprising a second motor symmetrically installed outside the left and right side walls, the lifting platform comprising a third motor at the lower part of the rust removal and paint spraying body, the lifting platform being controlled by the third motor so that metal pipes of different diameters on the roller are colinear with the clamping device on the axis, which has a good clamping effect on the metal pipes, the rust removal device being provided can make the rust removal sheet fully contact with the metal pipes, thereby improving the rust removal effect on the metal pipes, the metal pipes after rust removal can be sprayed with paint, thereby accelerating the production efficiency of the metal pipes.

[0004] In the above application, there are still some problems when rust removal and painting of metal pipes, such as:

[0005] First, in the above application, when rust removal is performed on metal pipes, if the sizes of the metal pipes vary greatly, the position distance between the rust removal equipment and the metal pipes cannot be adjusted well, so the practicality is low during operation.

[0006] Second, in the above application, when the rust remover is added to the outer surface of the metal pipe by spraying, most of the rust remover will splash to other places, which will cause the equipment to be contaminated by a large amount of rust remover, which is very inconvenient to clean and will also cause a large amount of rust remover to be wasted.

[0007] Third, there are many devices in the above application, and they are all scattered near the metal pipes. There is no connection between the devices, which will result in a large number of driving sources being required to drive these devices to operate, making the processing of the metal pipes too troublesome and costly.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] An embodiment of the present invention provides a metal pipe rust removal and paint spraying device, comprising a workbench 1, a pipe placing mechanism 2, a fixing mechanism 3, a moving mechanism 4, a pipe processing mechanism 5, a rust removal device 6 and a coating device 7, wherein the pipe placing mechanism 2 and the fixing mechanism 3 are both arranged on the workbench 1, the fixing mechanism 3 is located on one side of the pipe placing mechanism 2, and the fixing mechanism 3 is connected to the pipe placing mechanism 2, the moving mechanism 4 is arranged on the pipe placing mechanism 2, and the moving mechanism 4 is connected to the pipe placing mechanism 2, the pipe processing mechanism 5 is arranged on the moving mechanism 4, the rust removal device 6 and the coating device 7 are both arranged on the pipe processing mechanism 5, the rust removal device 6 and the coating device 7 are both connected to the pipe processing mechanism 5, and the working ends of the rust removal device 6 and the coating device 7 correspond to the metal pipe located on the pipe placing mechanism 2. In the present invention, the pipe placing mechanism 2 can be fixed by the fixing mechanism 3. When the fixing mechanism 3 releases the fixing of the pipe placing mechanism 2, one end of the pipe placing mechanism 2 can be disassembled, so that the metal pipe can be loaded onto the pipe placing mechanism 2 and the metal pipe can be unloaded from the pipe placing mechanism 2. When the moving mechanism 4 is in operation, it can drive the pipe processing mechanism 5 to move horizontally along the metal pipe. When the moving mechanism 4 is in operation, it can also drive the pipe placing mechanism 2, so that the pipe placing mechanism 2 drives the metal pipe to rotate. The contact between the rust removal device 6 and the working end of the coating and the metal pipe provided on the pipe processing mechanism 5 will be affected by the pipe processing mechanism 5. When the pipe processing mechanism 5 drives the rust removal device 6 to contact the metal pipe, the coating device 7 cannot contact the metal pipe.

Compared with the metal pipe rust removal and painting equipment in the prior art, the advantages of the present invention are as follows:

[0036] First, the present invention adopts a coating device 7 to replace the painting equipment in the prior art. When the rust inhibitor is applied to the metal pipe, since the working end of the coating device 7 is in direct contact with the surface of the metal pipe, the rust inhibitor will not splash to other places of the equipment, and the coating method can make the rust inhibitor basically act on the metal pipe, which will not cause a lot of waste.

[0037] Second, in the present invention, when the metal pipe is located on the pipe placing mechanism 2, it can be driven to rotate through the operation of the moving mechanism 4. When the metal pipe rotates, it can better cooperate with the rust removal equipment 6 and the coating equipment 7 to work, so that the outer surface of the metal pipe can be evenly coated with the rust inhibitor, and the outer surface of the metal pipe can be rust-removed. Moreover, when the moving mechanism 4 is in operation, it can also drive the pipe processing mechanism 5 to move, so that the pipe processing mechanism 5 drives the rust removal equipment 6 and the coating equipment 7 to move horizontally along the metal pipe. In this way, when the metal pipe rotates, the rust removal equipment 6 and the coating equipment 7 move synchronously, which makes it more convenient for the two to cooperate with each other and their efficiency will be better.

When the first bevel gear set 323 rotates, it will drive the transmission rod 324 to rotate the second bevel gear set 325 and the third bevel gear set 326. Since the second bevel gear set 325 and the third bevel gear set 326 in the present invention are mirror-imaged, when the second bevel gear set 325 and the third bevel gear set 326 in the present invention drive the two rotating shafts 314 to rotate, the two rotating shafts 314 will rotate in opposite directions, so that the two rotating shafts 314 will drive the two fixed rods to correspond to the two fixed frames 28, and vice versa, the two fixed rods can be separated from the two fixed frames 28.
