On the basis of the above embodiments, the technical features involved therein and the functions and roles that the technical features play in the technical solution are described in detail using the following paragraphs so as to help those skilled in the art to fully understand the technical solution and reproduce it.
Referring to fig. 1 to 5, when the application is in use, a travelling wheel or a travelling device can be arranged at the bottom of the upright post 1 so as to realize the movement of the whole structure to the position to be cleaned; when the position to be cleaned is a movable structure, such as a coal carriage, a cabin and the like, the upright post 1 can be fixedly connected with the base, and a space for parking the movable structure is formed in an outer frame formed by the upright post 1, the cross beam 2 and the longitudinal beam 4.
An operator realizes the horizontal movement of the movable beam 8 on the cross beam 2 along the cross beam sliding rail 3 and the cross beam sliding rod 6 through the longitudinal beam drivers 5 on the longitudinal beams 4 at two sides, and further realizes the fine adjustment of the initial positions of the negative pressure adsorption unit 18, the side plate cleaning unit 17 and the top cleaning unit 15.
The operator adjusts the lifting drive 10 so that the lifting frame 13 and the structure to which it is connected are adjusted in the vertical direction along the lifting travel groove 11 and the height during cleaning is adjusted.
After the negative pressure adsorption unit 18, the side plate cleaning unit 17 and the top cleaning unit 15 reach the corresponding height and horizontal position, an operator controls the adjusting frame driver 41 to realize that the L-shaped adjusting plate 24 slides outwards along the side plate shaft body 23 through the adjusting plate strip-shaped hole 25, so that the top cleaning unit 15 and the side plate cleaning unit 17 at the end part of the L-shaped adjusting plate 24 are respectively contacted with the top and the side wall of the position to be cleaned. The top cleaning unit 15 can drop the residual coal adhered to the top to the inside along with the horizontal movement of the lifting frame 13, and the side plate cleaning unit 17 can drive a plurality of side brushes 34 to rotate through the rotation of the side plate cleaning unit, so that the side brushes 34 rub (or flap) with the side walls, and the residual coal adhered to the side walls drops.
The roller body side brush plates 49 and the bottom brush bodies 50 positioned at the bottom of the side brush driving shaft 33 can collect and clean the residual coal at the two sides of the bottom to the middle, and the residual coal is fed into the inlet suction pipes 51 through the feeding roller group unit 20, the inlet suction pipes 51 are distributed in a plurality of directions of the longitudinal beams 4 (namely, the width direction of the whole device), and the inlet suction pipes 51 can absorb the residual coal under the negative pressure of the negative pressure absorption unit 18. In actual use, the negative pressure adsorption unit 18 should generate an air volume of more than 17000 m/h, and an air velocity of more than 90m/s should be generated at the inlet positions of the inlet suction pipe 51, the middle suction pipe 43. And PM10 filtering precision contained in the gas discharged by the filtering unit matched with the negative pressure adsorption unit 18 is more than or equal to 99, and dust concentration is 10mg/m, so as to meet the environmental protection requirement.
The middle suction pipe 43 is located in the bottom space formed by the inlet inclined plates 44, and the middle suction pipe 43 is located in a narrow space, so that the middle suction pipe 43 and the inlet suction pipe 51 can be used for cleaning residual coal, the middle suction pipe 43 is used for secondary tail sweeping operation, and the middle suction pipe 43 and the inlet suction pipe 51 at the tail position are matched again to realize three tail sweeping operations, so that the purpose of cleaning residual coal at the bottom is achieved.
In the process of repeatedly moving the lifting frame 13 in the horizontal direction driven by the longitudinal beam driver 5, residual coal at the bottom, residual coal at the top and residual coal at two sides can be cleaned to a great extent, the reciprocating frequency is mostly maintained at one time, and two or three times are performed under the condition that a small number of adhesion is heavier, so that a higher cleaning effect is maintained.
During the movement of the side plate cleaning unit 17, the operator can implement the set-up yoke plate drive 37 in order to achieve a better attachment cleaning effect of the side plate cleaning unit 17. Specifically, in the course of the link plate driver 37 driving the swing driving link plate 36 to move downward, the side brush swing driving plates 35 connected to both sides of the swing driving link plate 36 by fastening bolts can drive the hinge plate 31 to swing outward through the bar-shaped holes of the hinge ends, so that the side brush driving shafts 33, the side brushes 34 in the side plate cleaning unit 17 are closer to the side walls to increase the friction force. The side plate support wheels 16 connected to the L-shaped adjustment plate 24 between the side plate cleaning unit 17 and the top cleaning unit 15 are inflatable elastic spheres that enable the side plate cleaning unit 17 to move on the side walls and maintain a minimum allowed distance.
Finally, although the description has been described in terms of embodiments, not every embodiment is intended to include only a single embodiment, and such description is for clarity only, as one skilled in the art will recognize that the embodiments of the disclosure may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
