Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar rust removal, and specifically relates to a steel bar sandblasting treatment device. Background Art

[0002] The surface of steel bars exposed to the outside world for a long time will produce rust, and the rust will affect the adhesion strength between the steel bars and concrete. Therefore, the workers need to remove the rust from the steel bars. Currently, the steel bar surface can be sandblasted and rusted by a water sandblasting machine. The workers operate the pipes to spray water and sand on the outer wall of the steel bars, and remove the rust on different parts of the steel bars by moving the water and sand spraying position. However, there are a large number of steel cage columns on the construction site. The steel bars are woven and entangled with each other. The steel bars will block each other and limit the movement and angle adjustment of the water and sand spraying pipes. The side of the steel bar facing away from the workers is blocked by the steel bars themselves, and it is difficult to spray water and sand on the steel bar surface facing away from the workers. Even if the workers adjust the angle themselves, they will still be blocked by the other steel bars, and the efficiency of the workers in removing the rust from the steel bars will be greatly reduced.

[0017] In this embodiment: when a single steel bar is derusted, the plugging sleeve 4 and the elastic sealing cushion layer 41 cover the end of the lateral water-sand nozzle 31, and the lateral water-sand nozzle 31 can be blocked by the plugging sleeve 4 and the elastic sealing cushion layer 41, and the steel bar is derusted by spraying water and sand from the end of the large-diameter nozzle 3. The reset spring 5 and the support ring plate 51 cooperate to support the plugging sleeve 4 to maintain the stability of the position of the plugging sleeve 4 and the elastic sealing cushion layer 41. When it is necessary to derust the steel cage column, the staff pulls the traction rope 52 to drive the plugging sleeve 4 and the elastic sealing cushion layer 41 to move, so as to release the blockage of the lateral water-sand nozzle 31. During the process, the reset spring 5 is pulled and compressed by the traction rope 52, and the water and sand are transported to the large-diameter nozzle 3 through the water-sand conveying pipe 2. The water and sand are separated by the water-sand separation arc plate 32, and are directed to the lateral water-sand nozzle 3 through the guide arc plate 33. 1 conveying, the large diameter nozzle 3 and the four lateral water-sand nozzles 31 simultaneously spray water-sand in five directions, and the end opening of the large diameter nozzle 3 cooperates with the four lateral water-sand nozzles 31 distributed on the circumference so that the device can extend into the steel cage column to remove rust from multiple angles on the steel bars, so that the device can spray and remove rust on multiple steel bars at the same time, and the lateral spraying of water-sand will not be blocked by the forward steel bars, so that the rust removal work can be performed on the inner side of the steel bars facing away from the staff. The device can directly clean different sides of the steel bars efficiently, and there is no need to frequently adjust the angle of the large diameter nozzle 3 in a limited space, which can effectively improve the efficiency and effect of the rust removal of the device. When the four lateral water-sand nozzles 31 are opened, the efficiency of the water conveying body of the adjustable water supply pump 12 and the falling speed of the electric clamp butterfly valve 11 are increased by the controller to maintain the speed of spraying water-sand.

[0018] An arc guide pad 311 is fixedly connected to the outer wall of the lateral water-sand nozzle 31, and the water-sand separation arc plate 32 and the guide arc plate 33 are connected to the lateral water-sand nozzle 31, and the four water-sand separation arc plates 32 do not contact each other; by setting the arc guide pad 311, the elastic sealing pad layer 41 can be guided, so that the elastic sealing pad layer 41 can be more easily covered on the outer wall of the lateral water-sand nozzle 31, avoiding the elastic sealing pad layer 41 and the side wall of the lateral water-sand nozzle 31 from interfering with the blocking sleeve 4 and the elastic sealing pad layer 41. A distance is left between the four water-sand separation arc plates 32 so that part of the water and sand can be sprayed out through the end opening of the large-diameter nozzle 3.

[0019] An elastic sealing pad layer 41 is fixedly connected to the inner wall of the sealing sleeve 4, and the thickness of the elastic sealing pad layer 41 is greater than the distance between the inner wall of the sealing sleeve 4 and the lateral water-sand nozzle 31; when the elastic sealing pad layer 41 covers the end of the lateral water-sand nozzle 31, the elastic sealing pad layer 41 is squeezed by the sealing sleeve 4 and the lateral water-sand nozzle 31, and the elastic sealing pad layer 41 can increase the effect of sealing the opening of the lateral water-sand nozzle 31.

[0020] A return spring 5 is fixedly connected to the bottom end of the sealing sleeve 4, and a support ring plate 51 is fixedly connected to the bottom end of the return spring 5. The support ring plate 51 is fixedly connected to the large-diameter nozzle 3. A traction rope 52 is arranged in the return spring 5, and the traction rope 52 is fixedly connected to the sealing sleeve 4. The return spring 5 and the support ring plate 51 are arranged to support the sealing sleeve 4. When the sealing sleeve 4 is not pulled, the sealing sleeve 4 automatically covers the opening position of the end of the lateral water-sand nozzle 31 under the elastic force of the return spring 5. The traction rope 52 is arranged to facilitate the staff to pull the sealing sleeve 4 to remove the sealing sleeve 4 and the elastic sealing cushion layer 41 from the opening position of the lateral water-sand nozzle 31.

[0021] The outer wall of the water-sand conveying pipeline 2 is fixedly connected to a limit hook 21, and the end of the traction rope 52 is fixedly connected to a limit hanging ring 53, and the limit hanging ring 53 is detachably connected to the limit hook 21; by setting the limit hook 21 and the limit hanging ring 53, the traction rope 52 can be fixed, so that the staff does not need to pull the traction rope 52 for a long time, reducing the burden on the staff's hands.

[0022] The working principle and use process of the utility model are as follows: when a single steel bar is derusted, the plugging sleeve 4 and the elastic sealing pad layer 41 cover the end of the lateral water-sand nozzle 31, and the lateral water-sand nozzle 31 is blocked by the plugging sleeve 4 and the elastic sealing pad layer 41, and the water-sand nozzle 3 is sprayed from the end of the large-diameter nozzle 3 to derust the steel bar. When the steel bar cage column needs to be derusted, the staff pulls the traction rope 52 to drive the plugging sleeve 4 and the elastic sealing pad layer 41 to move, so as to release the blockage of the lateral water-sand nozzle 31, and the water-sand is transported to the large-diameter nozzle 3 through the water-sand conveying pipe 2. The water-sand separation arc plate 32 separates the water-sand and conveys the water-sand to the lateral water-sand nozzle 31 via the guide arc plate 33. The large-diameter nozzle 3 and the four lateral water-sand nozzles 31 simultaneously spray water-sand in five directions. The end opening of the large-diameter nozzle 3 cooperates with the four lateral water-sand nozzles 31 distributed on the circumference so that the device can extend into the steel cage column to remove rust on the steel bars at multiple angles. When the lateral water-sand nozzle 31 needs to be blocked again, the staff removes the limit hanging ring 53 from the limit hook 21, and the blocking sleeve 4 and the elastic sealing cushion layer 41 are automatically reset under the elastic force of the reset spring 5.
