However, in actual use, due to dust pollution in the coking production workshop, a lot of dust will remain on the outer surface of the bucket elevator after long-term use, which will not only increase the burden on the machine body and reduce the stability of the machine body during operation, but also easily cause cross contamination when transporting different materials, which is not conducive to the stable transportation of materials. The bucket elevator needs to be cleaned in time. However, conventional bucket elevators do not have external cleaning devices themselves, and often require manual cooperation for cleaning and wiping to achieve the cleaning and maintenance of the bucket elevator. There are problems such as inconvenient operation, time-consuming and labor-intensive, and low safety, which need to be improved. Utility Model Content

[0019] like Figures 1 to 6As shown, a coking plant hoist comprises a hoist body 2 fixed on a base 1, a motor 3 is fixedly mounted on the outer top of the hoist body 2, and the output shaft of the motor 3 faces upward and is coaxially fixedly connected to a turntable 4. A square positioning groove 5 is provided in the middle of the top surface of the turntable 4, and first electric push rods 6 are horizontally fixedly mounted on both the left and right sides, and the telescopic ends of the two first electric push rods 6 are arranged oppositely and fixedly connected to a fixing plate 7, and a plurality of fixing rods 8 distributed in a rectangular array are fixedly arranged on the opposite sides of the two fixing plates 7. A cleaning mechanism is provided on the turntable 4, and the cleaning mechanism comprises a square base 9, and a plurality of blind holes 10 are provided on the left and right sides of the base 9, and the lower part of the base 9 is inserted into the positioning groove 5, and the two fixing plates 7 are respectively abutted on the left and right sides of the base 9, and the fixing rods 8 correspond to and are inserted into the blind holes 10 on the same side. A conveying box 11 is fixed on the top of the base 9. The top of the conveying box 11 is rotatably connected to a connecting pipe 12 and the side is connected to a horizontal pipe 14. The connecting pipe 12 is coaxially arranged with the output shaft of the motor 3 and a quick connector 13 is coaxially fixed on the top. The tail end of the horizontal pipe 14 is fixedly connected to a vertical pipe 15. On the side of the vertical pipe 15 close to the elevator body 2, a plurality of horizontally fixed second electric push rods 16 are distributed in intervals up and down. The telescopic end of the second electric push rod 16 faces the side where the elevator body 2 is located and is fixedly connected to a nozzle 17. The outlet of the nozzle 17 faces the side where the elevator body 2 is located and the top is connected to the side of the vertical pipe 15 through a hose 18.

[0020] During normal operation, the cleaning mechanism is separated from the hoist body 2, so as not to affect the lifting and transportation of the hoist body 2. When the outer surface of the hoist body 2 needs to be cleaned, the base 9 can be aligned with the positioning groove 5 and placed in place in the shutdown state, and then the two first electric push rods 6 can be operated to extend the telescopic ends, driving the fixed plate 7 to move toward the base 9 until the fixed plate 7 is pressed against the corresponding side of the base 9, and the fixed rod 8 is inserted into the corresponding blind hole 10, and the base 9 is pressed and plugged and locked, so that the fixed installation of the cleaning mechanism can be completed, and the installation is stable and does not affect subsequent use. Then, the connecting pipe 12 is connected to the existing water source through the quick connector 13, and the flushing operation during cleaning can be carried out.

After flushing, first disconnect the connection between the connecting pipe 12 and the water source through the quick connector 13, and then connect the connecting pipe 12 to the existing hot air source through the quick connector 13, and then spray hot air to the outer surface of the elevator body 2 according to the above steps to achieve the air drying operation during cleaning. In this way, the automatic, comprehensive and efficient flushing and air-drying of the hoist body 2 can be realized, the operation is simpler, time-saving and labor-saving, the operation is safer and more practical;

[0021] After cleaning is completed, the two first electric push rods 6 are operated again to shrink their telescopic ends, driving the fixed plate 7 to retreat until the fixed rod 8 withdraws from the corresponding blind hole 10, and then the base 9 is pulled out, and the cleaning mechanism can be disassembled so as not to affect the subsequent use of the elevator body 2. The operation is simple, making the whole more convenient and practical. The elevator body 2 can adopt the existing conventional bucket elevator, and its specific structure and working principle are all existing technologies, which will not be described in detail here. The water source and the hot air source can both adopt the existing technology, and the hot air source can specifically adopt the existing conventional hot air dryer. The quick connector 13 can adopt the existing technology, which generally includes a male head and a female head.
