The frozen coal cleaning device of the embodiment is directed to a railway KM70 type coal carriage 6 (indicated by two-dot chain lines in FIGS. 1-3). The bottom of the carriage is provided with four gates 601 which are respectively arranged at the bottoms of two sides of the carriage. For unloading convenience, the bottom plate of the carriage is not flat, but is provided with a long ridge 602 in an inverted V shape along the advancing direction of the carriage, the two sides of the long ridge are inclined carriage bottom plates, a front plate 603 and a rear plate 604 of the carriage are also inclined, and the middle part of the carriage is also provided with a transverse ridge 605 in an inverted V shape, as shown in FIGS. 1-3.

Due to the particularity of the carriage bottom plate, the coal is difficult to be removed by manpower or common mechanical equipment, and a special coal removing device is designed for the embodiment. The embodiment uses three sets of facilities aiming at the particularity of the carriage and respectively aims at the front section, the rear section and the middle section of the carriage.

The electric heater may be coupled to the blower through a heating wire, and a hot blast pipe 7 (see fig. 3) needs to be connected to a special heating furnace.

Example eight:

the embodiment is a method for cleaning the frozen coal at the bottom of a self-moving railway KM70 type coal transportation carriage by using the frozen coal cleaning device in the embodiment.

The basic idea of this embodiment is to utilize the round brush that has rotatory sharp sword to cut and the breakage to frozen coal, and the round brush moves along the inclined plane in carriage to sweep the inclined plane, and utilize the helical blade of round outside the round surface of round brush and the sharp sword that sets up on the blade outer fringe to cut and the breakage to frozen coal, realize the clearance of remaining frozen coal.

The method comprises the following steps:

step 1, entering a station: the cleaned carriage enters the frame of the cleaning device, and the cleaning device is in an original state before the cleaned carriage enters the frame, wherein the original state is as follows: each telescopic column is in the shortest retraction state, and each rolling brush is in a horizontal state; the carriage position detecting sensor detects the accurate position of the carriage, the front telescopic column and the rear telescopic column are aligned to the front edge and the rear edge of the carriage, and the middle telescopic column is aligned to the bulge in the carriage.

When cleaning begins, the car first comes under the frame of the truck, roughly aligning the position of the three cars. When the cleaning device is in an original state, the rolling brush stops rotating and swinging, the front end trolley is aligned with the top of the front edge inclined plate of the carriage, the rear end trolley is aligned with the top of the rear edge inclined plate of the carriage, and the middle trolley is aligned with the transverse ridge in the middle of the carriage. When the sensors and the central control unit are provided, the initial state is also the starting point for the initialization of the automation device.

Step 2, stretching out the rolling brush: each telescopic column extends out, and under the monitoring of the anti-collision sensor, the front telescopic column and the rear telescopic column extend to the positions where the rolling brush approaches to the front inclined plate and the rear inclined plate of the carriage; the middle telescopic column extends to a position where the rolling brush is close to the inverted cone inclined plate in the middle of the carriage; and then rotating the rotation central axis of each rolling brush to enable the rotation central axis of each rolling brush to be parallel to the corresponding inclined plane.

The telescopic column drives the rolling brush to move towards the inner wall of the carriage, and in order to prevent the rolling brush from colliding with the carriage plate, a laser radar or other sensors capable of monitoring the distance are required to be used for measuring the distance between the rolling brush and the carriage plate surface. The approach distance is approximately between 5 and 10 centimeters.

And 3, removing residual coal of the front, rear and middle transverse ridge inclined plates: starting the air heater, vertically freezing the hot air to the coal, and simultaneously starting each rolling brush to enable each rolling brush to rotate around the respective rotation central axis; meanwhile, the front trolley and the rear trolley respectively slowly run backwards and forwards (the two trolleys oppositely move towards the middle part of the carriage), and the telescopic column extends downwards to enable the front rolling brush and the rear rolling brush to move downwards along the corresponding inclined surfaces (namely the rotary central axis of the rolling brush moves in the inclined surface and keeps parallel to the inclined surface of the carriage), and simultaneously the rotary central axis of the rolling brush swings in the plane of the corresponding inclined plate to enable the front rolling brush and the rear rolling brush to generate the action of sweeping the front inclined plate and the rear inclined plate; meanwhile, the rotation center line of the middle rolling brush also swings along the inclined plane, so that the middle rolling brush performs the action of sweeping the middle inverted cone inclined plate.

When the carriage plates which are inclined forwards and backwards are cleaned, the rolling brush swings along the carriage plate surface, and when the middle ridge is cleaned, the rolling brush swings along the inclined plate surface in a V shape, so that cleaning is realized.

And 4, removing residual coal of the long ridge inclined plate: after residual coal on the front and rear inclined plates and the inclined plate of the middle ridge inverted cone of the carriage is removed, the middle telescopic column is retracted and returns to the original state; the front and rear trolleys continue to move backwards and forwards (the front and rear trolleys move towards the middle of the carriage), and the swing of the central axes of the front and rear rolling brushes is changed into the swing along the inclined plane of the long ridge until the front and rear trolleys are converged at the middle trolley.

When cleaning the middle spine, the middle trolley is different in static state and is contracted to lift the rolling brush.

And 5, finishing the clearing operation: the front and rear telescopic columns are retracted, and the front and rear trolleys respectively move forwards and backwards to return to the original state.

And after the cleaning is finished, the front trolley, the rear trolley and the middle trolley return to the original positions to clean the next carriage.

Finally, it should be noted that the above is only intended to illustrate the technical solution of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the preferred arrangement, it should be understood by those skilled in the art that modifications and equivalent substitutions can be made to the technical solution of the present invention (such as the type of the similar car, the power and power transmission manner of each action, the sequence of the steps, etc.) without departing from the spirit and scope of the technical solution of the present invention.
