Background Art

[0002] Storage tanks are equipment for storing liquids, gases and other substances. The quality of their inner walls is directly related to the quality, safety and life of the stored materials. Defects in the inner wall can cause liquid and gas leakage, affecting production safety. Sandblasting can remove burrs, oxides, rust and other impurities on the inner wall of the tank, ensure that the inner wall surface is smooth and flat, and avoid minor defects such as lines and holes on the inner wall of the tank, thereby improving the quality of the inner wall of the tank. The inner wall of some water storage tanks needs to be sprayed with anti-rust paint. The principle is to form a protective film by coating the metal surface with anti-rust paint, which serves to isolate the water inside the tank from contact with air and prevent rust. Anti-rust paint is usually made of durable materials such as polyurethane and epoxy resin. These materials are water-resistant, acid-resistant, weather-resistant and highly adhesive, and can protect the inner wall of the tank for a long time.

[0003] At present, the sandblasting and painting of the inner wall of medium and large storage tanks are all done by workers using safety belts and safety nets to ensure the personal safety of construction workers. Manual construction not only has low work efficiency, but also still has safety risks.

[0022] Example 1

[0023] As shown in the figure, the base 1 is fixedly connected to the support base 2, and the positioning cylinder 3 is installed on the support base 2 through a bearing. Limiting mechanisms are provided at both ends of the positioning cylinder 3. The limiting mechanisms are composed of an adjusting screw 41 and a limiting plate 42. The adjusting screw 41 is threadedly connected to the threaded hole set on the positioning cylinder 3. The end of the adjusting screw 41 is provided with a limiting plate 42. A driven wheel 55 is installed on the outer wall of one end of the positioning cylinder 3. The driven wheel 55 is meshed and connected with the driving wheel 54. The driving wheel 54 is connected to the reducer 53 through a connecting shaft. The reducer 53 is connected to the driving motor 51 through a coupling 52. The reducer 53 and the driving motor 51 are both installed on the base 1.

[0024] The center of the interior of the positioning cylinder 3 is penetrated by the movable guide assembly. One end of the guide rail 61 in the movable guide rail assembly is fixedly mounted on the main support frame 91. The other end of the guide rail 61 is connected to the auxiliary support frame 92 by bolts. The auxiliary support frame 92 is fixed to the base 1 by fastening bolts, and the main support frame 91 is also mounted on the base 1. The guide rail 61 is mounted with a screw rod 63 through a bearing. One end of the screw rod 63 is connected to the motor 62 mounted at the end of the guide rail 61. The screw rod 63 is threadedly connected to the slider 64. The limiting holes set at both ends of the slider 64 are penetrated by the limiting columns 65 installed on the guide rail 61.

[0025] like Figure 4, electric telescopic push rods 71 ​​are respectively installed at both ends of the slider 64, and the telescopic ends of the electric telescopic rods 71 ​​are connected to the mounting plates 8 through the connecting plates 72. A high-pressure sandblasting gun 82 is installed on one mounting plate 8, and a paint spraying gun 81 is installed on the other mounting plate 8. The high-pressure sandblasting gun 82 is connected to external sandblasting boxes and other equipment, and the paint spraying gun 81 is connected to external paint spraying boxes and other equipment to transport the required materials for spraying and provide power to the spray gun. A control chassis 10 is installed on the base 1, and a control panel 101 is provided on the control chassis 10 for starting and controlling the operation of the equipment. The controller arranged in the control chassis 10 is electrically connected to the drive motor 51, the motor 62, the electric telescopic rod 71, the high-pressure sandblasting gun 82, the paint spraying gun 81 and other electronic components to control the operation of the electronic equipment in this application.

[0026] It should be noted that the connection between the paint spray gun and external equipment such as the paint spray box and the connection between the high-pressure sandblasting gun and external equipment such as the sandblasting box are all existing technical means, so this application does not draw or describe this part of the structure in detail in the figure.

[0027] Example 2

[0028] When using the utility model, the staff sends the storage tank 111 into the positioning cylinder 3 through a conveying device such as a crane, and adjusts each set of limit mechanisms by rotating the adjusting screw 41. In this application, three sets of limit mechanisms are set at each end of the positioning cylinder 3 to limit and fix the storage tank 111. The angle between two adjacent limit mechanisms is 120 degrees. The limit mechanism is adjusted so that the limit plate 42 is against the outer wall of the storage tank 111. After the positioning is completed, the staff fixes the auxiliary support frame 92 to the base 1 by bolts and connects it to one end of the guide rail 61, and supports both ends of the guide rail 61 with the main support frame 91. The auxiliary support frame 92 is designed to be detachable, which does not affect the movement and transportation of the storage tank 111 into the positioning cylinder 3 and the removal after construction, and can also support one end of the guide rail 61.

[0029] The staff operates on the control panel 101 on the control box 10 to select whether to spray paint or sandblast. After receiving the command, the controller transmits it to the corresponding electronic components to work. The electric telescopic rod 71 controls the movement of the paint spray gun 81 or the high-pressure sandblasting gun 82 to adjust the distance between the spray gun and the inner wall of the storage tank 111. Then the driving motor 51 drives the driven wheel 55 to rotate through the driving wheel 54, controls the fixed cylinder 3 to drive the storage tank 111 to rotate, and the spray gun sprays paint or sandblasts the inner wall of the rotating storage tank 111. During the spraying process, the motor 62 and the screw 63 in the moving guide rail assembly realize the axial movement of the slider 64, control the spray gun to move linearly inside the storage tank 111, and perform complete painting or sandblasting on the inner wall of the storage tank 111. The whole process only requires manual operation of the control box and the disassembly and installation of the auxiliary support frame 92, which greatly reduces the labor intensity of manual labor. Mechanical equipment is used for spraying work, which also greatly improves work efficiency.
