Description

TECHNICAL FIELD

[0001] The present application relates to a kind of cement plant circular cement silo wall cleaning machinery, especially a kind of hydraulic transmission cleaning machinery. BACKGROUND

[0002] The cement produced by cement production enterprises needs to be stored, and the storage silo is circular, with a diameter generally between 10 meters and 20 meters, and a height between 20 meters and 30 meters. Due to the influence of wind and rain, the inner wall of the cement silo is damp, causing the cement in contact with the wall to condense and adhere to the wall. The industry term is hanging wall. The longer the time, the thicker the wall, resulting in a decrease in inventory, directly affecting the normal production of cement. Therefore, the cement plant needs to arrange personnel to clean the hanging wall in the cement silo every year. There is only one ventilation opening at the top of the cement silo, which can be accessed. The size of the ventilation opening is generally 0.8 meters to 1 meter square. The ventilation opening is offset from the center of the silo. In order to ensure the safety of personnel, it is now strictly prohibited for personnel to enter the silo for work. The current method is to hang a horizontal bar with a rope, the front end of the horizontal bar is suspended with an air motor, an iron chain is installed on the output shaft of the motor, and an iron block is tied on the iron chain. In this way, the air motor is started to drive the iron chain to rotate at high speed, which is used to knock the hanging wall in the silo to achieve the purpose of removing the hanging wall. This method is difficult for the operator to control the direction and position of the knocking, so the work efficiency is very low. SUMMARY

[0007] The present application will be further described below in combination with the description of the drawings and specific embodiments: the hydraulic cement silo cleaning machine, as shown in Figure 1As shown, it includes a chassis 12, which is a hollow structure with a diameter similar to the ventilation holes at the top of the cement silo. Three support beams 2 are installed around the chassis 12. These support beams are telescopic to ensure maximum support span and stability of the silo cleaning machine. Adjusting screws 1 are installed at the front ends of each of the three support beams 2 to adjust the balance of the silo cleaning machine. An external gear slewing bearing 11 is mounted on the chassis 12. A rotating chassis 10 is mounted on the slewing bearing 11. A hydraulic winch 3, a hydraulic slewing device 4, and a lifting frame 7 are mounted on the rotating chassis 10. A guide frame 9 is fixed on the lifting frame 7, and a guide wheel is inside the guide frame 9. The lifting frame 7 is connected to the rotating chassis 10 by a pin. At the same time, the lifting frame 7 is also hinged to the piston rod of the hydraulic cylinder 5 on one side of the guide frame 9. The bottom end of the hydraulic cylinder 5 is hinged to the rotating chassis. When the hydraulic cylinder is operated to extend or retract, it can drive the lifting frame 7 to swing at a certain angle. The output shaft gear of the hydraulic rotary device 4 extends out from under the rotating chassis 10 and meshes with the gear on the fixed plate of the slewing bearing 11. When the hydraulic rotary device 4 is operated to rotate, it can drive the rotating chassis 10 to rotate as a whole.

[0008] Telescopic crushing mechanism, such as Figure 2 As shown, it mainly consists of a vertical beam 13, a telescopic arm 23, and a crushing mechanism 24. A guide rail 15 is fixedly installed at the lower end of the vertical beam 13, forming a single unit. A sliding sleeve 17 is installed on the guide rail 15, allowing it to slide up and down along the guide rail 15. A hydraulic cylinder 14 is installed inside the vertical beam 13, with its cylinder body hinged to the upper end of the vertical beam 13 and its piston rod hinged to the sliding sleeve 17. One end of the beam 19 of the telescopic arm 23 is hinged to the sliding sleeve 17, and one end of the beam 21 of the telescopic arm 23 is hinged to the lower end of the guide rail 15 by a pin 22. The telescopic arm 23 is formed by the connection of beam 19 and beam 21 via pin 20. The telescopic boom 23 is horizontally extended by the hinged structures forming a parallelogram. The opening and closing of beams 19 and 21 allows for the extension and retraction of the boom 23. In other words, the hydraulic cylinder 14 drives the sliding sleeve 17 to move up and down along the guide rail 15. Since one end of beam 21 of the telescopic boom 23 is positioned at the lower end of the guide rail 15 by pin 22, and one end of beam 19 of the telescopic boom 23 is hinged to the sliding sleeve 17 by pin 18, the extension and retraction of the hydraulic cylinder 14 drives the opening and closing of beams 19 and 21 of the telescopic boom 23, thus achieving the extension and retraction of the boom 23. The distance of extension and retraction of the boom 23 can be controlled by controlling the stroke of the hydraulic cylinder 14, allowing it to be positioned at a specific point. A crushing mechanism 24 is installed at the front end of the telescopic boom 23. The crushing mechanism 24 mainly consists of a hydraulic motor and a pick-type crushing head 25. A connecting plate is installed on the output shaft of the hydraulic motor, and the pick-type crushing heads 25 are evenly distributed on the connecting plate. When the hydraulic motor rotates at high speed, it drives the pick-type crushing heads 25 to rotate and crush the wall hanging on the cement silo boom.

[0009] The installation and working process of the hydraulic cement cleaning machine is as follows: firstly, the base plate 12, the slewing bearing 11 and the rotating base plate 10 are assembled into an integrated body on the ground, and the hydraulic winch 3, the hydraulic slewing device 4 and the hydraulic jack 5 are fixedly installed on the rotating base plate 10. The assembled base frame is hoisted to the cement silo by a crane, and the central hole of the base plate 12 is aligned with the ventilation hole above the cement silo at a center point; three supporting beams 2 are installed on the base plate 12, and since the ventilation hole above the cement silo is not located at the center of the cement silo, the length of the supporting beams 2 must be adjusted so as to extend to the maximum position of the periphery of the cement silo, and the rotating base plate 10 is adjusted to a horizontal state. The lifting frame 7 is installed, and the lifting frame 7 is hingedly connected to the piston rod end of the oil cylinder 5 already installed on the rotating base plate 10 by a pin shaft, and the basic frame is installed. In the case that the telescopic arm 23 is completely retracted, the steel wire rope 6 pulled by the hydraulic winch 3 is passed through the rope wheel at the top end of the lifting frame 7 to hoist the telescopic crushing mechanism, and the telescopic crushing mechanism is lowered into the cement silo through the central hole of the base plate 12 and the ventilation hole above the cement silo, the vertical beam 13 is clamped into the guide wheel in the guide frame 9, the hydraulic power system is connected, the jack 14 is operated to extend and drive the sliding sleeve 17 to descend, and the sliding sleeve 17 drives the telescopic arm 23 to extend horizontally, when the crushing mechanism 24 installed at the front end of the telescopic arm 23 reaches the wall-hung position to be crushed, the hydraulic motor is started to crush; at the same time, the hydraulic slewing device 4 is operated to work, and the rotating base plate 10 is driven to rotate as a whole, and since the telescopic crushing mechanism is positioned in the guide frame 9, it also rotates, and the crushing mechanism 24 performs crushing work along the periphery of the cement silo wall, when the rotating base plate 10 rotates one round or to a certain point, the hydraulic winch 3 is operated to lower the telescopic crushing mechanism by a certain distance, i.e. a working step distance, to perform the next working cycle. With the progress of the work, when the vertical beam 13 cannot descend far enough, the vertical beam 13 is pinned in the guide frame 9 by a pin shaft, the lifting steel wire rope 6 connected to the top end of the vertical beam 13 is removed, the standard vertical beam 8 is hoisted, and is connected to the vertical beam 13 by bolts, the pin for pinning the vertical beam 13 is removed, and the normal work can be performed, and the process is repeated until the cleaning work is completed.

[0010] The cleaning machine can install a camera on the telescopic arm 23, and one person outside the silo can concentrate on operating the actions of each part of the cleaning machine, so that safety and high efficiency are realized.
