The two anti-rollover wheels 206 are respectively in rolling contact with the lower end surfaces of the outer sides of the upper wings of the two running rails 1, thereby ensuring that the running trolley 2 will not roll over when running on the running rails 1.

[0049] During operation, the rotary motor 404 drives the driving gear to rotate. Since the driving gear is meshed with the driven gear ring, and the driven gear ring is fixed on the inner ring of the slewing bearing 403, the driving gear begins to roll around the driven gear ring, thereby driving the operating platform 3 and the outer ring of the slewing bearing 403 to rotate around the inner ring of the slewing bearing 403, thereby realizing the rotation of the operating platform 3.

[0050] The cantilever assembly 5 includes a first cantilever 501, a second cantilever 502, an intermediate platform 503, a fixed platform 504, a first oil cylinder 505, and a second oil cylinder 506.

The two ends of the first oil cylinder 505 are rotatably connected to the operating platform 3 and the first cantilever 501, respectively. The angle change of the first cantilever 501 is controlled by the extension and contraction of the first oil cylinder 505; the two ends of the second oil cylinder 506 are rotatably connected to the first cantilever 501 and the second cantilever 502, respectively. The angle change of the second cantilever 502 relative to the first cantilever 501 is controlled by the extension and contraction of the second oil cylinder 506.

[0051] The first cantilever 501 includes four first connecting rods which are parallel to each other and of equal length. The four first connecting rods are arranged in a square array. The lower ends of the four first connecting rods are rotatably connected to the upper end surface of the operating platform 3 through a hinge seat, and the upper ends of the four first connecting rods are rotatably connected to the lower end surface of the intermediate platform 503 through a hinge seat.

[0055] The lifting assembly 7 includes a hoist 701 , a drum 702 , a hoisting rope 703 , an upper guide roller 704 , and a lower guide roller 705 .

[0056] A winch 701 is fixedly installed on the upper end surface of the middle platform 503, and a drum 702 is fixedly installed on the output shaft of the winch 701. The drum 702 is divided into two independent working areas, and a group of winch ropes 703 are respectively wound and fixed in each working area.

[0057] Two through holes are symmetrically arranged on both sides of the dust removal port of the fixed platform 504, and two lower guide rollers 705 are rotatably arranged inside the through holes. An upper guide roller 704 is rotatably arranged on the side of the middle platform 503 close to the fixed platform 504. The free end of the hoisting rope 703 passes through the through hole on the same side after passing around the upper guide roller 704 and is fixedly connected to the dust removal cover 6. The hoisting rope 703 rolls and contacts with the lower guide roller 705 on one side during the process of passing through the through hole.

[0058] During operation, the forward and reverse rotation of the elevator drives the reel 702 to rotate forward and reverse, thereby realizing the retraction and extension of the hoisting rope 703. When the hoisting rope 703 is retracted, the hoisting rope 703 drives the dust cover 6 to rise, and the telescopic tube 601 begins to shrink; when the hoisting rope 703 is released, the hoisting rope 703 loses the upward pulling force on the dust cover 6, the dust cover 6 begins to descend, and the telescopic tube 601 begins to extend, thereby realizing the control of the height of the dust cover 6.

[0059] The dust removal assembly 8 includes an exhaust fan 801 , a filter box 802 , an input air duct 803 , an intermediate air duct 804 , and an output air duct 805 .

The two ends of the intermediate air duct 804 are respectively connected to the outlet of the filter box 802 and the inlet of the exhaust fan 801. An output air duct 805 is arranged at the outlet of the exhaust fan 801.

[0061] The working principle of the utility model is:

[0062] During operation, the driving motor 207 drives the driving wheel 208 to rotate, and the driving wheel 208 drives the driven wheel 209 to rotate through the synchronous belt 210, and the driven wheel 209 drives the front rotating shaft 202 to rotate, and the rotating shaft 202 drives the walking wheel 203 to roll on the driving track 1, thereby realizing the forward and backward movement of the driving trolley 2 on the driving track 1, thereby moving the dust removal hood 6 to the side of the position where dust removal is required.

[0063] Then the rotary motor 404 drives the driving gear to rotate. Since the driving gear is meshed with the driven gear ring, and the driven gear ring is fixed on the inner ring of the slewing bearing 403, the driving gear begins to roll around the driven gear ring, thereby driving the operating platform 3 and the outer ring of the slewing bearing 403 to rotate around the inner ring of the slewing bearing 403, thereby realizing the rotation of the operating platform 3, so that the dust removal hood 6 is oriented to the position where dust removal is required.

[0064] Then, the angle change of the first cantilever 501 is controlled by extending and retracting the first cylinder 505, and the angle change of the second cantilever 502 relative to the first cantilever 501 is controlled by extending and retracting the second cylinder 506, so that the first cantilever 501 and the second cantilever 502 reach the optimal working angle, so that the dust removal hood 6 is located above the position where dust removal is required.

[0065] Then, the reel 702 is driven to rotate forward and backward by the forward and backward rotation of the elevator, thereby realizing the retraction and release of the hoisting rope 703. When the hoisting rope 703 is retracted, the hoisting rope 703 drives the dust hood 6 to rise, and the telescopic tube 601 begins to shrink; when the hoisting rope 703 is released, the hoisting rope 703 loses the upward pulling force on the dust hood 6, the dust hood 6 begins to descend, and the telescopic tube 601 begins to extend, thereby realizing the control of the height of the dust hood 6, so that the distance between the dust hood 6 and the position where dust removal is required reaches the optimal working distance.

[0066] Then, the exhaust fan 801 is controlled to start working. The exhaust fan 801 sucks the dust under the dust cover 6 into the filter box 802 through the dust cover 6 and the input air duct 803. After being filtered by the filter box 802, the dust is discharged to the outside through the exhaust fan 801 and the output air duct 805.

[0067] The utility model can move the dust hood 6 to the side of the position where dust removal is required through the traveling trolley 2, can direct the dust hood 6 toward the position where dust removal is required through the rotating assembly 4, can move the dust hood 6 above the position where dust removal is required through the cantilever assembly 5, and can make the distance between the dust hood 6 and the position where dust removal is required reach the optimal working distance through the lifting assembly 7, so that only one set of cantilever dust hoods is needed to cover a large working area, thereby reducing the number of arrangements, reducing costs, and saving working area; when dust removal is not needed, the first cylinder 505 and the second cylinder 506 can be retracted, the first cantilever 501 and the second cantilever 502 can be folded, and the traveling trolley 2 can be moved to the storage area, so that it will not affect the progress of other work processes, and it is more convenient and flexible.

[0068] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
