Description

Technical Field

[0001] This utility model relates to the field of metallurgical sintering technology, and in particular to a sintering machine trolley wheel residue cleaning device. Background Technology

[0002] During normal production operation of the sintering machine, due to the high temperature and the rolling action of the bearings, grease inside the trolley wheels flows out from the overflow port. Then, the grease adheres to the fallen sintering materials or dust, forming sludge on the outer side of the wheel end face. This seriously affects the workers' ability to replenish grease to the grease fitting of the trolley wheels, reduces the service life of the trolley wheels, and increases the labor intensity of the workers.

[0003] Chinese patent CN219223317U discloses a dust removal device for the end face of a sintering machine trolley wheel. The contact distance between the dust removal belt and the trolley wheel is adjusted by a screw, and the dust removal belt is used to clean the end face of the wheel. However, the trolley wheel is also equipped with an oil nozzle, which is located in the center of a groove with a protrusion on the end face of the wheel. Therefore, the belt cannot remove the sludge inside the groove. Furthermore, if the wheel is cleaned while the trolley is moving, there is severe relative friction between the dust removal belt and the end face of the wheel, and the dust removal belt is prone to wear and needs to be replaced frequently. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a sintering machine trolley wheel residue cleaning device, which can clean the oil stains and adhering materials spilled from the trolley wheels during normal operation of the sintering machine.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A sintering machine trolley wheel residue cleaning device includes a rotating mechanism fixed on the sintering machine frame. The rotating mechanism has a sleeve on the side facing the trolley wheel, which is perpendicular to the wheel end face. One end of the sleeve is open and the other end is closed. A movable column is provided inside the open end. The movable column and the closed end of the sleeve form a pressure space. A brush fixing plate is provided at the other end of the movable column. A brush is provided on the brush fixing plate. The brush bristles are flexible and their length is greater than the distance between the brush fixing plate and the trolley wheel.

[0007] The aforementioned sintering machine trolley wheel residue cleaning device includes a rotating mechanism comprising a turntable and a rotating motor. The center of the turntable is connected to the output end of the rotating motor, and a sleeve is connected to the edge of the other side.

[0008] In the aforementioned sintering machine trolley wheel residue cleaning device, the outer surface of the sleeve and the movable column is fitted with a spring, and the two ends of the spring are respectively connected to the turntable and the brush fixing plate.

[0009] The beneficial effects of adopting the above technical solution are as follows:

[0010] This invention uses a rotary motor to drive the brush fixing plate to rotate, thereby driving the brush to clean the end face of the wheel. It can not only clean the end face of the trolley wheel, but also reach into the groove to clean the oil nozzle and its surrounding area. Since the brush bristles directly contact the surface of the trolley wheel, there is no need to adjust the distance between the brush and the trolley wheel. In addition, a sleeve, movable column and spring are set between the turntable and the brush fixing plate to offset part of the pressure of the trolley wheel on the brush.

[0011] This invention enables the cleaning of the trolley wheels while the sintering machine is running normally, facilitating the replenishment of grease to the grease fittings on the trolley wheels by the workers, thereby improving the service life of the trolley wheels and reducing the labor intensity of the workers.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-2 As shown, this utility model includes a rotating mechanism, which is fixedly connected to the sintering machine frame 1 via a fixed plate. A sleeve 3 is provided on the side of the sleeve facing the trolley wheel 2. The sleeve 3 is perpendicular to the wheel end face, with one end open and the other closed. A movable column 4 is provided inside the open end, forming a pressure space with the closed end of the sleeve 3. A brush fixing plate 5 is provided at the other end of the movable column 4, and a brush 6 is provided on the brush fixing plate 5. The bristles of the brush 6 are flexible, and their length is greater than the distance between the brush fixing plate 5 and the trolley wheel 2. When cleaning the trolley wheel 2, there is no need to adjust the distance between the brush 6 and the trolley wheel 2. During the movement of the trolley wheel 2, the bristles of the brush 6 directly contact the surface of the trolley wheel 2. The rotating mechanism drives the brush fixing plate 5 to rotate, thereby driving the brush 6 to clean the wheel end face. Some of the bristles enter the groove 10 of the trolley wheel 2 to clean the oil nozzle and its surrounding area, facilitating the worker to replenish grease to the oil nozzle of the trolley wheel 2.

[0017] The rotating mechanism of this utility model includes a turntable 7 and a rotary motor 8. A bracket (not shown in the figure) is provided between the rotary motor 8 and the turntable 7. A bearing is provided on the bracket. The output end of the rotary motor 8 passes through the bracket and connects to the center of the turntable 7. The longitudinal section of the turntable 7 is circular. A sleeve 3 is connected to the edge of its other side. The sleeve 3 is connected to the center of the brush fixing plate through a movable column 4. Compared with the brush fixing plate 5 being directly connected to the output end of the rotary motor 8, this increases the cleaning range of the brush 6.

[0018] In addition, the outer surfaces of the sleeve 3 and the movable column 4 of this utility model are fitted with springs 9. The two ends of the springs 9 are respectively connected to the turntable 7 and the brush fixing plate 5. Through the sleeve 3, the movable column 4 and the springs 9, part of the squeezing of the trolley wheel 2 on the brush 6 can be offset.

[0019] Workflow:

[0020] This utility model is installed on the side of the trolley wheel 2 and is fixedly connected to the sintering machine frame 1 through a fixing plate. The distance between the bristles of the brush 6 and the trolley wheel 2 is negative. During the movement of the trolley, the rotary motor 8 drives the turntable 7 to rotate, which in turn drives the brush 6 to clean the end face of the wheel and the inside of the groove. Since the sintering machine trolley moves back and forth on the track, even if the cross-section of the brush 6 is smaller than the cross-section of the trolley wheel 2, one cleaning cannot clean the entire end face of the wheel. However, the wheel is repeatedly cleaned during operation, and the cleaning position is different each time. In the process of multiple repetitions, it is equivalent to cleaning the entire end face of the trolley wheel 2.

[0021] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this invention.
