When the sand blasting treatment before the thermal spraying is needed to be carried out on the shaft diameter part with serious abrasion of the rotor shaft of the steam turbine:

(1) preparation work: firstly, the staff pushes the waste sand collecting device for shaft repairing and sand blasting to the lower part of the shaft diameter part of the steam turbine rotor shaft.

Secondly, starting the oil cylinder 2-2, extending a piston rod 2-2-1 of the oil cylinder, enabling the piston rod 2-2-1 of the extended oil cylinder to push a top plate 2-1 to move upwards, enabling the top plate 2-1 to support the collecting barrel to move upwards together until the shaft diameter part of the rotor shaft of the steam turbine is inserted into a slot 1-5 of the collecting barrel, and closing the oil cylinder 2-2. During the upward movement of the top plate 2-1, the top plate 2-1 carries the guide rod 2-5 to move upward, so that the guide rod 2-5 slides upwards in the guide cylinder 2-6 on the upper end surface of the bottom plate 2-3.

Thirdly, pushing the cover plate 1-7 to the right to enable the cover plate 1-7 to slide rightwards in the cover plate sliding groove 1-8, so that the cover plate 1-7 covers a part of the upper opening end of the collecting barrel, which is close to the first barrel wall 1-1.

(2) Sand blasting treatment: the staff uses the sand blasting rifle to carry out the sandblast to the shaft diameter position of steam turbine rotor shaft, and the waste sand that produces during the sandblast directly falls into in the collecting vessel and is collected by the collecting vessel.

(3) And (4) follow-up work: firstly, after sand blasting is finished, starting the oil cylinder 2-2, shortening a piston rod 2-2-1 of the oil cylinder, pulling a top plate 2-1 downwards by the shortened piston rod 2-2-1 of the oil cylinder, moving a collecting bucket downwards along with the top plate 2-1 until a shaft diameter part of a rotor shaft of a steam turbine is withdrawn from a slot 1-5, and closing the oil cylinder 2-2. In the process of moving the top plate 2-1 downwards, the top plate 2-1 carries the guide rod 2-5, so that the guide rod 2-5 slides downwards in the guide cylinder 2-6 on the upper end surface of the bottom plate 2-3.

And secondly, pushing the shaft repairing and sand blasting waste sand collecting device of the embodiment away from the lower part of the shaft diameter part of the rotor shaft of the steam turbine.

After the waste sand in the collecting vessel is collected to full, need clear up the waste sand of collecting in the collecting vessel, the clearance process is as follows:

(1) the staff puts the braided bag in the below of collecting vessel.

(2) The inserted rod 7-1 is pulled to withdraw the inserted rod 7-1 from the second insertion hole 6-1 of the adjusting rod 6, and at the moment, the spring 7-3 is in a compressed state so as to enable the adjusting rod 6 to slide up and down in the adjusting cylinder 5.

(3) The adjusting rod 6 is pushed downwards to enable the adjusting rod 6 to slide downwards in the adjusting cylinder 5, the lower end of the adjusting rod 6 pushes the sliding block 4 to enable the sliding block 4 to slide downwards and rightwards along the edge of the bearing plate 3, so that the bearing plate 3 rotates clockwise by taking the hinged part of the bearing plate 3 and the first barrel wall 1-1 as a rotation center, after the bearing plate 3 rotates for a certain angle, pulling of the inserting rod 7-1 is released, the inserting rod 7-1 is re-inserted into the second inserting hole 6-1 of the adjusting rod 6 under the action of elastic force of the spring 7-3, and the adjusting rod 6 and the adjusting cylinder 5 are fixed together.

When the bearing plate 3 rotates clockwise by taking the hinged part of the bearing plate 3 and the first barrel wall 1-1 as a rotation center, the waste sand collected in the collecting barrel flows out from a gap between the bearing plate 3 and the third barrel wall 1-3 and flows into a woven bag for collecting the waste sand, so that the waste sand in the collecting barrel is cleaned.

And when the bearing plate 3 rotates clockwise by taking the hinged part of the bearing plate 3 and the first barrel wall 1-1 as a rotation center, the baffle 3-1 can move along with the bearing plate 3, so that waste sand on the bearing plate 3 is prevented from flowing out from a gap between the bearing plate 3 and the lower end of the second barrel wall 1-2 and a gap between the bearing plate 3 and the lower end of the fourth barrel wall 1-4, the waste sand on the bearing plate 3 can only flow out from a gap between the bearing plate 3 and the third barrel wall 1-3, the waste sand on the bearing plate 3 is prevented from flowing everywhere, and the cleaning is more convenient.

(4) After the waste sand in the collecting barrel is emptied, the inserted rod 7-1 is firstly dragged to enable the inserted rod 7-1 to be withdrawn from the second inserting hole 6-1 of the adjusting rod 6. Then, the adjusting rod 6 is pulled upwards, so that the adjusting rod 6 interacts upwards in the adjusting cylinder 5, the lower end of the adjusting rod 6 drives the sliding block 4 to enable the sliding block 4 to slide leftwards and upwards along the edge of the bearing plate 3, and therefore the bearing plate 3 rotates anticlockwise by taking the hinged part of the bearing plate 3 and the first barrel wall 1-1 as a rotation center, and the bearing plate 3 blocks the lower open end of the collecting barrel again. And finally, the inserted rod 7-1 is loosened, and the inserted rod 7-1 is reinserted into the second insertion hole 6-1 of the adjusting rod 6 under the action of the elastic force of the spring 7-3, so that the adjusting rod 6 and the adjusting cylinder 5 are fixed together. So that the collecting barrel can be used again to collect the waste sand.

Through the use process, the following steps are obtained: according to the waste sand collecting device for shaft repairing and sand blasting, on one hand, the lower open end of the collecting barrel can be blocked by the receiving plate 3, so that the collecting barrel can be used for receiving waste sand during sand blasting treatment, the waste sand is prevented from falling on the ground, workers do not need to clean and collect the waste sand, and the labor intensity of the workers is reduced; on the other hand, can also let the lower open end of collecting vessel open through rotating to accept board 3 to let the interior waste sand of collecting vessel unload from the lower open end of collecting vessel, conveniently clear up the waste sand in the collecting vessel.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
