Spiral sheets 7 are arranged 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 open car side wall are arranged between two adjacent spiral sheets 7. The wire brush 8 and the pick 9 are used to clean the frozen coal stuck to the side wall of the open car.

[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 concentrated 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, and 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 formed by the pick 9 is larger than the outer diameter of the spiral sheet 7, and the cross-sectional diameter formed by the wire brush 8 is larger than the cross-sectional diameter formed by the pick 9. The cross-sectional area 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 pick 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 the pick 9 needs to be installed to break the frozen coal, and then the wire brush 8 does further cleaning. 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 circumference of the drum. Preferably, the bottom of the pick seat is an arc surface that matches the outer circumference 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 is fixedly connected to the drum 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 arranged axially along the side wall cleaning device, and the upper support frame 12 and the lower support frame 14 are respectively connected to the upper fixing seat 13 and the lower fixing seat 15; the upper fixing seat 13 and the lower fixing seat 15 used to support the side wall cleaning device are fixedly connected to the central frame 20. Preferably, the upper support frame 12 is arranged near the upper coupling 2, and the lower support frame 14 is arranged near the lower coupling 4, so as to increase the stability of the side wall 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 hinged to the upper fixing seat 13; the lower support frame 14 is hinged to the lower fixing seat 15. The side wall cleaning device is connected to the driving device 21, and the lateral width of the side wall cleaning device is adjusted by the driving device 21 (the applicant has applied for a patent for the driving device separately, which will not be repeated here) to meet the side wall cleaning requirements of different vehicle models with different compartment widths.

[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 reinforcing ribs arranged along the side wall of the carriage, so as to avoid the side wall cleaning device from colliding with the reinforcing ribs and damaging the carriage.

[0043] The vertical spiral open car side wall cleaning device of the present invention is firstly provided with upper and lower fixing seats of the side wall cleaning device on both sides of a central frame 20, and connected with a 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 body 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, and as the central frame 20 moves longitudinally along the car body, 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 car body.

[0044] The vertical spiral open car side wall cleaning device of the present invention utilizes picks and wire brushes to clean frozen coal on the side wall, replacing manual work, which is safe and efficient, and the working efficiency is greatly improved; two support frames and a 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 and vibrating too much, thereby affecting the cleaning effect; the reinforcing rib protrusion structure in the middle part of the open car side wall is effectively avoided, and the picks are prevented from scratching the car body; the fixed seat and the support frame are connected by a pin shaft, which can be suitable for the car body widths of different models, has a high degree of integration, and is convenient and efficient.
