Description

Technical Field

[0001] This utility model relates to the technical field of storage tank maintenance equipment, and in particular to a large storage tank outer wall cleaning and polishing device. Background Technology

[0002] Large storage tanks are widely used in industries such as chemical, petroleum, and food processing to store various liquids or gases. Due to prolonged exposure to the external environment, dust, oil, rust, and other contaminants easily accumulate on the outer walls of these tanks, affecting not only their appearance but also potentially shortening their lifespan. Therefore, regular cleaning and polishing maintenance of the outer walls of large storage tanks is necessary.

[0003] Currently, the cleaning and polishing of the outer walls of large storage tanks is mostly done manually or with simple mechanical devices. Manual cleaning and polishing is labor-intensive and inefficient. Existing mechanical devices are limited in function, mostly only capable of performing one of the cleaning or polishing tasks, requiring equipment replacement to complete all maintenance work. This is cumbersome and inefficient. Furthermore, due to the large diameter of the storage tank outer walls, polishing with polishing wheels easily leads to uneven and incomplete polishing, affecting the cleaning effect. Existing devices are also difficult to adapt to storage tanks of different diameters, exhibiting poor versatility. To address the problems of the existing technology, this paper proposes a device for cleaning and polishing the outer walls of large storage tanks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing a large-scale tank outer wall cleaning and polishing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large storage tank outer wall cleaning and polishing device includes a base, two high-friction rotating rollers rotatably mounted on the top of the base, a drive assembly between the two rotating rollers and the base, a large storage tank body movably placed on the top of the two rotating rollers, two sliding grooves opened on the top of the base, a gantry frame slidably mounted in the two sliding grooves, a polishing disc and four nozzles mounted on the gantry frame, and a cleaning and polishing mechanism between the polishing disc, the four nozzles and the gantry frame.

[0007] As a preferred embodiment of this utility model, an electric slide block is slidably fitted in each of the two slide grooves, and the gantry frame is fixedly connected to the top of the two electric slide blocks.

[0008] In a preferred embodiment of this invention, the drive assembly includes two support plates fixedly connected to the top of the base, two rotating shafts rotatably connected between the two support plates, two rotating rollers fixedly sleeved on the outer side of the corresponding rotating shafts, worm gears fixedly sleeved on the outer side of the rotating shafts, a drive motor fixedly installed on the front side of the front support plate, a drive shaft fixedly connected to the output shaft of the drive motor, and two worms fixedly sleeved on the outer side of the drive shaft, the two worms meshing with the corresponding worm gears respectively.

[0009] As a preferred embodiment of this utility model, two connecting plates are fixedly connected to the front side of the front support plate, the drive motor is fixedly connected to one side of the left connecting plate, and the drive shaft is rotatably connected between the two connecting plates.

[0010] In a preferred embodiment of this invention, the cleaning and polishing mechanism includes a servo motor, a water pump, and a cleaning liquid tank, which are fixedly connected to the top of the gantry from left to right. A lifting screw is fixedly connected to the output shaft of the servo motor. A lifting plate is threaded onto the outer side of the lifting screw. Two vertical rods are fixedly connected to the bottom of the lifting plate. The bottom ends of the two vertical rods are fixedly connected to the same mounting plate. A rotary motor is fixedly connected to the top of the mounting plate. The polishing disc is fixedly connected to the output shaft of the rotary motor.

[0011] In a preferred embodiment of this invention, the water pump is connected to the bottom of one side of the cleaning fluid tank, a telescopic pipe is fixedly connected to the bottom of the water pump, an annular pipe is fixedly connected to the bottom of the telescopic pipe, and the tops of the four nozzles are all fixedly connected to the bottom of the annular pipe.

[0012] As a preferred embodiment of this invention, a limiting plate is fixedly connected to the top of the lifting screw, and the limiting plate cooperates with the lifting plate.

[0013] As a preferred embodiment of this utility model, the top of the base is provided with a frame-shaped water storage tank, and a drain pipe is fixedly connected to the inner front wall of the frame-shaped water storage tank.

[0014] In this utility model, a large storage tank outer wall cleaning and polishing device is described. The gantry frame slides to the front or back side, so as not to hinder the large storage tank body to be cleaned and polished from being suspended on two rotating rollers and located between two support plates. The drive motor can be started by the controller set next to the device. The drive motor drives the drive shaft and two worm gears to rotate synchronously. The two worm gears drive the two worm wheels and the rotating shaft to rotate synchronously and slowly. The two rotating shafts drive the two rotating rollers to rotate synchronously and slowly. Because the surface friction coefficient of the rotating rollers is high, the rotation of the large storage tank body can be slowly driven, so as to thoroughly and evenly clean and polish the outer surface of the large storage tank body.

[0015] In this utility model, a large storage tank outer wall cleaning and polishing device is described. A servo motor drives the rotation of a lifting screw, which in turn moves the lifting plate, two vertical rods, and mounting plate downwards, causing the polishing disc to abut against the top of the large storage tank body. A rotary motor drives the polishing disc to rotate, thereby polishing the outer wall of the large storage tank body. Simultaneously, a water pump draws the cleaning liquid from the cleaning liquid tank into the telescopic pipe and annular pipe, and finally sprays high-pressure water from four nozzles to clean the outer wall of the large storage tank body. The sliding of the electric slide in the slide groove drives the gantry, polishing disc, and four nozzles to reciprocate back and forth, thereby repeatedly cleaning and polishing the outer wall of the large storage tank body. The sprayed clean water can promptly wash away the debris formed during polishing, improving the polishing effect. Wastewater flows into a frame-shaped water storage tank and is then discharged through a drain pipe.

[0016] This utility model has a reasonable structural design. Through the drive component, it drives the rotation of the large storage tank body. At the same time, through the back-and-forth movement of the polishing disc and nozzle, it can thoroughly and evenly clean and polish the outer wall of the entire large storage tank body, which greatly improves the cleaning and polishing effect. In addition, large storage tank bodies of different sizes can be placed on the two rotating rollers, which improves the versatility of the device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A large storage tank outer wall cleaning and polishing device includes a base 1. Two high-friction rotating rollers 63 are rotatably mounted on the top of the base 1. A drive assembly 6 is provided between the two rotating rollers 63 and the base 1. A large storage tank body 5 is movably placed on the top of the two rotating rollers 63. Two sliding grooves 3 are opened on the top of the base 1. A gantry frame 2 is slidably mounted in the two sliding grooves 3. A polishing disc 710 and four nozzles 713 are mounted on the gantry frame 2. A cleaning and polishing mechanism 7 is provided between the polishing disc 710, the four nozzles 713 and the gantry frame 2. Electric sliding blocks 4 are slidably mounted in both sliding grooves 3. The gantry frame 2 is fixedly connected to the top of the two electric sliding blocks 4.

[0024] Furthermore, refer to Figure 1 and Figure 3 The drive assembly 6 includes two support plates 61 fixedly connected to the top of the base 1. Two rotating shafts 62 are rotatably connected between the two support plates 61. Two rotating rollers 63 are respectively fixedly sleeved on the outer side of the corresponding rotating shafts 62. Worm gears 64 are fixedly sleeved on the outer side of the rotating shafts 62. A drive motor 66 is fixedly installed on the front side of the front support plate 61. A drive shaft 67 is fixedly connected to the output shaft of the drive motor 66. Two worms 68 are fixedly sleeved on the outer side of the drive shaft 67. The two worms 68 mesh with the corresponding worm gears 64 respectively.

[0025] Using the above scheme: Start the drive motor 66, which drives the drive shaft 67 and the two worm gears 68 to rotate synchronously. The two worm gears 68 drive the two worm wheels 64 and the rotating shaft 62 to rotate synchronously and slowly. The two rotating shafts 62 drive the two rotating rollers 63 to rotate synchronously and slowly. Because the rotating rollers 63 have a high coefficient of friction, they can slowly drive the rotation of the large storage tank body 5, thereby enabling a comprehensive and uniform cleaning and polishing of the outer surface of the large storage tank body 5.

[0026] Furthermore, two connecting plates 65 are fixedly connected to the front side of the front support plate 61. The drive motor 66 is fixedly connected to one side of the left connecting plate 65, and the drive shaft 67 is rotatably connected between the two connecting plates 65. This can support and fix the drive motor 66, and at the same time support the drive shaft 67, making its rotation more stable.

[0027] Furthermore, refer to Figure 1 , Figure 2 and Figure 4The cleaning and polishing mechanism 7 includes a servo motor 74, a water pump 72, and a cleaning fluid tank 71, which are fixedly connected to the top of the gantry frame 2 from left to right. A lifting screw 75 is fixedly connected to the output shaft of the servo motor 74. A lifting plate 76 is threaded on the outer side of the lifting screw 75. Two vertical rods 73 are fixedly connected to the bottom of the lifting plate 76. The bottom ends of the two vertical rods 73 are fixedly connected to the same mounting plate 711. A rotary motor 79 is fixedly connected to the top of the mounting plate 711. A polishing disc 710 is fixedly connected to the output shaft of the rotary motor 79. The water pump 72 is connected to the bottom of one side of the cleaning fluid tank 71. A telescopic pipe 78 is fixedly connected to the bottom of the water pump 72. An annular pipe 712 is fixedly connected to the bottom of the telescopic pipe 78. The top ends of the four nozzles 713 are all fixedly connected to the bottom of the annular pipe 712.

[0028] The above scheme is adopted as follows: the servo motor 74 drives the rotation of the lifting screw 75, which in turn drives the lifting plate 76, the two vertical rods 73 and the mounting plate 711 to move downward, so that the polishing disc 710 abuts against the top of the large storage tank body 5. The rotary motor 79 drives the rotation of the polishing disc 710, thereby polishing the surface of the large storage tank body 5. At the same time, the water pump 72 can pump the cleaning liquid in the cleaning liquid tank 71 into the telescopic pipe 78 and the annular pipe 712. Finally, high-pressure water is sprayed from the four nozzles 713 to clean the surface of the large storage tank body 5. The electric slide 4 slides in the slide groove 3, which drives the gantry 2, the polishing disc 710 and the four nozzles 713 to move back and forth, thereby repeatedly cleaning and polishing the surface of the large storage tank body 5. The sprayed water can also wash away the debris formed during polishing in time, improving the polishing effect.

[0029] Furthermore, a limiting plate 77 is fixedly connected to the top of the lifting screw 75. The limiting plate 77 cooperates with the lifting plate 76 to limit the lifting plate 76.

[0030] Furthermore, a frame-shaped water storage tank 8 is provided on the top of the base 1, and a drain pipe 9 is fixedly connected to the inner wall of the front side of the frame-shaped water storage tank 8. Sewage flows into the frame-shaped water storage tank 8 and is then discharged through the drain pipe 9.

[0031] In this invention, during use, the gantry 2 slides to the front or rearmost position, thus allowing the large storage tank body 5 to be cleaned and polished to be suspended on the two rotating rollers 63 and positioned between the two support plates 61. A controller located beside the device activates the drive motor 66, which drives the drive shaft 67 and the two worm gears 68 to rotate synchronously. The two worm gears 68 drive the two worm wheels 64 and the rotating shaft 62 to rotate synchronously and slowly. The two rotating shafts 62 drive the two rotating rollers 63 to rotate synchronously and slowly. Due to the high coefficient of friction of the rotating rollers 63, the rotation of the large storage tank body 5 can be slowly driven, thus enabling comprehensive and uniform cleaning and polishing of the outer surface of the large storage tank body 5. A servo motor 74 drives the rotation of the lifting screw 75, which in turn drives the lifting... The downward movement of plate 76, two vertical rods 73, and mounting plate 711 causes the polishing disc 710 to come into contact with the top of the large storage tank body 5. The rotating motor 79 drives the polishing disc 710 to rotate, thereby polishing the surface of the large storage tank body 5. At the same time, the water pump 72 can pump the cleaning liquid in the cleaning liquid tank 71 into the telescopic pipe 78 and the annular pipe 712. Finally, high-pressure water is sprayed from the four nozzles 713 to clean the surface of the large storage tank body 5. The sliding of the electric slide 4 in the slide groove 3 drives the gantry 2, polishing disc 710, and four nozzles 713 to move back and forth, thereby repeatedly cleaning and polishing the surface of the large storage tank body 5. The sprayed clean water can wash away the polishing debris in time, improving the polishing effect. The wastewater flows into the frame-shaped water storage tank 8 and is then discharged through the drain pipe 9.
