This results in the existing spraying method that the reactor can be sprayed only vertically, but the spraying method is difficult to operate, and the worker has difficulty in uniformly covering the surface of the reactor with the paint, which is time-consuming, laborious and wasteful.
Disclosure of Invention
The invention aims to provide a spraying device capable of spraying the surface of a large-sized tiltable hollow reactor.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
The spraying device for the surface treatment of the air-core reactor comprises a clamping assembly and a spraying assembly; the clamping assembly comprises a supporting base, and a power assembly capable of driving the supporting base to turn over to one side of the spraying assembly is connected to the supporting base; the bearing base is internally provided with a vertically arranged bearing column, and the bearing column is provided with a plurality of load blocks for bearing radial and axial loads; one end of the bearing column extends out of the supporting base and is connected with a rotary table part capable of rotating relative to the supporting base, and a lower clamp for clamping a workpiece is arranged on the periphery of the rotary table part; an upper clamp matched with the lower clamp is also connected to the supporting base, and the upper clamp is positioned above the rotating disc piece; the spray assembly includes a paint reservoir and a plurality of nozzles positioned above the rotor, the paint reservoir being in communication with the nozzles.
The principle of the invention is as follows:
The spraying device has an unlocking state and a locking state. When the spraying device is in an unlocking state, the upper clamp and the nozzle are moved away from the area where the turntable piece is located, and the lower clamp is loosened, at this time, a worker can lift and put the workpiece on the turntable piece. After the workpiece is placed into the rotating disc, the lower clamp locks the main framework of the workpiece, and meanwhile, the upper clamp is moved back to the area where the rotating disc is located to lock the top of the workpiece, so that the spraying device enters a locking state. Then, according to the technological requirements of spraying, the power assembly drives the supporting base to turn over to one side of the spraying assembly until the included angle between the supporting base and the ground meets the technological requirements. Based on the weight of the reactor, the spraying device is generally provided with a safe overturning angle, and the supporting base can stay at any angle between 0 DEG and the safe overturning angle under the drive of the power assembly, so that multi-angle spraying is realized. After the supporting base is turned over, the nozzle is moved back to the area where the turntable is located, and the paint in the paint storage is sprayed on the surface of the workpiece through the nozzle. Due to the included angle formed between the supporting base and the ground, the paint can flow on the surface of the reactor, so that the paint is uniformly coated on the surface of the reactor.
The larger the weight of the large reactor, the larger the inclination angle of the large reactor, and the larger the load bearing column bears. In order to make the load born by the bearing column be in a proper range, the spraying device is provided with a component for limiting the maximum overturning angle of the supporting base, therefore, the clamping assembly can also comprise a limiting seat, the limiting seat is positioned in front of the overturning direction of the supporting base, and a limiting surface which can be abutted against the supporting base is formed on the limiting seat. The limiting surface is inclined to the ground, and the supporting base is turned over to be attached to the limiting surface, namely the maximum turning angle of the supporting base. The inclination angle of the reactor can be effectively limited by the inclination adjustment of the limiting surface.

Through the cooperation of columnar accommodation space and thrust roller bearing, effectively restrict the position of spandrel post in limited space, thrust roller bearing can bear the radial load because of the reactor slope brings and because of the axial load that the reactor dead weight drove well, guarantees that whole spraying device normally uses.
In order to ensure that the lower clamp can fix the main framework of the reactor, the lower clamp can comprise lower clamping blocks symmetrically arranged on two sides of the rotating disc piece relative to the bearing column, and the outer contour of the lower clamping blocks is arc-shaped and the inner arc of the arc-shaped is towards the bearing column.

In addition, a plurality of lock catches used for fixing the reactor can be arranged on the circumference of the turntable, and the lock catches are turned over and buckled on the main framework of the reactor to play a role in assisting in fixing the reactor.
In order to ensure the stable rotation of the rotating disc piece, the bearing post can be provided with a driven gear which rotates synchronously with the rotating disc piece, and the driven gear is positioned at one side of the rotating disc piece, which faces the supporting base; the rotary table driving device is arranged on the supporting base and used for driving the rotary table to rotate, the output end of the rotary table driving device is connected with a driving gear, and the driving gear is meshed with a driven gear, so that the driven gear is driven to rotate, and the rotary table is driven to rotate. Due to the stability of gear transmission, when the reactor is driven to rotate by the turntable, the rotating stability of the reactor can be ensured.
Besides the stable rotation of the rotary plate, the spraying device also has a braking function, and the rotation of the rotary plate can be timely braked based on the field condition, so that a plurality of braking motors can be arranged on the supporting base, and the braking motors are connected with braking gears meshed with the driven gears. When the rotary disc piece needs emergency braking, the braking motor can be started to drive the braking gear to rotate, so that the rotation of the braking gear is slower than the rotation speed of the driven gear, the rotation of the driven gear is forcedly reduced gradually, and finally the emergency braking of the rotary disc piece is realized.
