[0025] See attached Figure 1 The utility model discloses a gondola side wall cleaning mechanism, comprising a motor 1, an upper coupling 2, an upper roller shaft 3, a lower coupling 4, a lower roller shaft 5, and a bottom disc wire brush 6. The motor 1, the upper coupling 2, the upper roller shaft 3, the lower coupling 4, the lower roller shaft 5, and the bottom disc wire brush 6 are sequentially connected from top to bottom. Spiral blades 7 are provided on the roller surfaces of the upper roller shaft 3 and the lower roller shaft 5. A wire brush 8 and a pick 9 for cleaning the sticky coal on the gondola side wall are provided between two adjacent spiral blades 7. The wire brush 8 and the pick 9 are used to clean the frozen coal stuck to the gondola side wall.

[0026] A bottom disc wire brush 6 is fixedly installed at the lower end of the lower drum shaft 5. The bottom disc wire brush 6 is used to clean the frozen coal at the bottom side walls of the carriage and the connected corners of the bottom of the carriage, and to concentrate the sticky coal / frozen coal cleaned from the side walls to the middle of the carriage, so as to facilitate the centralized transportation of the cleaned coal out of the carriage.

[0027] Furthermore, the disc 10 of the bottom disc wire brush 6 is fixedly mounted on the lower end of the lower drum shaft 5 , and the wire brush is fixedly mounted on the disc 10 via a mounting seat 11 .

[0028] Furthermore, the bottom disc wire brush 6 has more than three brushes, which are evenly distributed along the circumference of the disc 10. The multiple brushes are tilted to form a cone, which can clean the sticky coal at the corners without leaving any dead angles.

[0029] Between two adjacent spiral pieces 7 of the upper drum shaft 3 and the lower drum shaft 5, more than three wire brushes 8 are evenly distributed along the drum circumference, and more than three picks 9 are evenly distributed along the drum circumference. Preferably, the wire brushes 8 and picks 9 are arranged in a spiral shape along the drum.

[0030] The cross-sectional diameter of the cutting teeth 9 is larger than the outer diameter of the spiral sheet 7 , and the cross-sectional diameter of the wire brush 8 is larger than the cross-sectional diameter of the cutting teeth 9 . The cross-sectional diameter described here is a plane perpendicular to the axis of the drum.

[0031] The cross-sectional diameter of the wire brush 8 is 5 to 10 cm larger than the cross-sectional diameter of the cutting teeth 9 .

[0032] When the temperature is low in winter, the frozen coal on the side wall of the carriage cannot be cleaned by the wire brush 8 alone, and it is necessary to install the pick 9, which breaks up the frozen coal and then further cleans it with the wire brush 8. When there is no frozen coal on the side wall of the carriage, only the wire brush 8 is installed to complete the cleaning work of the side wall of the carriage, and there is no need to install the pick.

[0033] Adjacent wire brushes 8 and picks 9 are staggered in radial direction, which is beneficial to improving cleaning efficiency and obtaining better cleaning effect.

[0034] The pick seat of the pick 9 is fixedly connected to the outer circle of the drum. Preferably, the bottom of the pick seat is an arc surface that matches the outer circle of the drum. The pick seat and the drum are fixedly connected by welding.

[0035] The brush holder of the wire brush 8 is fixedly connected to the outer circle of the drum, and the handle of the wire brush 8 is fixedly installed in the slot of the brush holder. Preferably, the bottom of the brush holder is an arc surface that matches the outer circle of the drum, and the brush holder and the drum are fixedly connected by welding.

[0036] The wire brush 8 can be installed on the drum surface of the upper drum shaft 3 and the lower drum shaft 5, or on the side of the spiral blade 7 (such as Figure 2 shown).

[0037] An upper support frame 12 and a lower support frame 14 are provided axially along the sidewall cleaning device. The upper support frame 12 and the lower support frame 14 are connected to an upper fixing seat 13 and a lower fixing seat 15, respectively. The upper fixing seat 13 and the lower fixing seat 15 for supporting the sidewall cleaning device are fixedly connected to the central frame 20. Preferably, the upper support frame 12 is provided near the upper coupling 2, and the lower support frame 14 is provided near the lower coupling 4, to increase the stability of the sidewall cleaning device.

[0038] like Figure 3 As shown, the side wall cleaning devices are symmetrically arranged in pairs on both sides of the central frame 20, and the central frame 20 moves longitudinally along the car body; preferably, two pairs of side wall cleaning devices are arranged on both sides of the central frame 20.

[0039] The upper support frame 12 is hingedly connected to the upper fixing seat 13, and the lower support frame 14 is hingedly connected to the lower fixing seat 15. The sidewall cleaning device is connected to a drive device 21, which adjusts the lateral width of the sidewall cleaning device (the applicant has separately applied for a patent for the drive device, which will not be described here) to meet the sidewall cleaning requirements of different vehicle models.

[0040] The side wall cleaning device is connected to the driving device 21 , and the lateral distance between the side wall cleaning devices on both sides of the central frame 20 is adjusted by the driving device 21 .

[0041] When the upper support frame 12 and the upper fixing seat 13, and the lower support frame 14 and the lower fixing seat 15 are fixedly connected by bolts, the distance between the side wall cleaning devices fixedly installed on both sides of the central frame 20 is fixed and cannot be adjusted, and is only suitable for cleaning a single vehicle model.

[0042] Furthermore, the lower support frame 14 is arranged at a height that is the same as the height of the reinforcement ribs arranged along the side wall of the carriage, so as to avoid the side wall cleaning device colliding with the reinforcement ribs and damaging the carriage.

[0043] The utility model relates to a side wall cleaning mechanism for an open car. First, the upper and lower fixing seats of the side wall cleaning device are installed on both sides of a central frame 20 and connected to the driving device 21 on the central frame 20. The driving device 21 adjusts the distance between the side wall cleaning devices on both sides of the central frame 20 according to the width of the vehicle compartment to be cleaned. The motor 1 is started, and the motor 1 drives the upper roller shaft 3 and the lower roller shaft 5 to rotate. As the central frame 20 moves longitudinally along the compartment, the wire brush 8 and / or the pick 9 installed on the roller, and the bottom disc wire brush 6 installed at the lower end of the lower roller shaft 5 clean the sticky coal or frozen coal on the side wall of the compartment.

[0044] The utility model discloses a side wall cleaning mechanism for an open car, uses picks and a wire brush to clean the frozen coal on the side wall, replaces manual work, is safe and efficient, and greatly improves work efficiency; the two support frames and the fixed seat are provided, which can better fix the cleaning device, and prevent the side wall cleaning device from working unstably due to the cleaning device being too long or vibrating too much, thereby affecting the cleaning effect; effectively avoids the reinforcing rib protrusion structure in the middle part of the side wall of the open car, and prevents the picks from scratching the car body; the fixed seat and the support frame are connected by a pin shaft, which can be applied to the car body widths of different models, has a high degree of integration, and is convenient and efficient.

[0045] It should be noted that the above-mentioned embodiments are examples rather than limitations of the present invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the claims of this patent.
