Description

Railway wagon carriage inner wall cleaning device

Technical Field

The invention belongs to the field of railway freight car discharging devices, and particularly relates to a device for cleaning and recovering materials adhered to the inner wall of a carriage of a bulk railway freight car.

Background

The railway has the advantages of large transportation capacity, low energy consumption, less emission and less pollution. The transportation of bulk materials such as coal, ore and the like occupies more than seven times of the railway transportation volume. In the long-distance transportation process of the bulk materials, due to factors such as water content, temperature, vehicle pressing and the like, the bulk materials hardened on the side wall and the bottom of the carriage are difficult to unload, particularly the hardened bulk materials of the carriage are hardened and frozen in winter in the north, the carriage transportation capacity is about 10%, and even the whole vehicle is frozen when the hardened bulk materials are serious.

According to the information, a plurality of methods for cleaning hardened or frozen residual materials in the carriage are mainly manual cleaning and mechanical cleaning. The manual cleaning is thorough, but the efficiency is low, the cost is high, and the safety is low. Mechanical cleaning is efficient but not thorough. The inventor of the invention has applied for national invention and utility model patent as patent inventor in the beginning of this year: the device for cleaning and recovering the adhesion materials on the inner wall of the bulk material wagon carriage is disclosed in the patent application number: 201920206226.5, and 201910119766.4. The railway wagon carriage inner wall cleaning device can be used in a matched mode with a conventional railway bulk material wagon carriage inner wall adhesion material cleaning and recovering device, and can also be used as an independent unit. For convenience of description, some of the contents continue to be part of the last patent and are described in particular herein.

And left and right guide seats C3 and C3 ', wedge-shaped reinforcing blocks C4 and C4' and guide wheels C5 and C5 are respectively arranged below the two ends of the left and right cross beams.

The structure of the cleaning device D is shown in fig. 5: the cleaning machine is composed of a cleaning frame D1, a cleaning roller D2, a roller frame D3, a traction motor D4, a fixed pulley D5 and a cleaning mechanism D6.

The cleaning frame D1 is structured as shown in fig. 5: the rectangular cleaning frame D1 is connected with a steel wire rope B4 through a hanging seat D1.1; the cleaning frame D1 is provided with two transverse guide rails D2.1, and the transverse guide rails are provided with longitudinal rollers D2.2. And two sides of the transverse guide rail are respectively provided with a transverse roller D2.2.

The structure of the cleaning roller is shown in fig. 6: the cleaning roller D2 is a cylindrical roller which is fully distributed with steel wire brushes and is provided with a motor, and obstacle avoidance push rods D2.3 are arranged on the circumferences close to the two ends; d2.4 is a telescopic roller seat.

The clearing mechanism is shown in figure 7: a transverse roller D6.2 is arranged on the longitudinal guide rail D6.1, and the hydraulic cylinder D6.3 drives the roller seat to reciprocate.

The invention has the advantages and positive effects that: the invention realizes mechanization and automation of carriage cleaning work for loading and transporting bulk materials, saves labor force and improves safety and production efficiency.

The specific implementation mode is as follows:

when cleaning the bonding bulk materials on the four walls and the bottom in the wagon compartment, dragging the compartment to the position near the lower part of the portal A; the portal A and the movable trolley B1 are adjusted to be right above the boxcar E; starting a hoisting motor set B4 on the lifting mechanism B, and putting down the positioning and reinforcing device C and the cleaning device D which are connected together; when the positioning and reinforcing device C contacts the top of the boxcar E, the positioning and reinforcing device C stops falling, and the wedge-shaped reinforcing blocks C4, C4' and C6 wedge-shaped positioning blocks reinforce and position the boxcar E; after the vibration cleaning device D is separated from the positioning reinforcing device C, the vibration cleaning device D continuously falls, the position sensor feeds back signals, and the roller and the steel wire brush rotate to clean the four walls of the carriage. When the falling process encounters a protruded obstacle such as a reinforcing rib plate in a carriage, the obstacle avoidance push rod D2.3 can push the roller and the roller seat D2.4 to retreat, so that the roller seat avoids the horizontal reinforcing rib plate, and the damage to the boxcar E and the roller is avoided. When the roller falls to the bottom of the carriage, the traction motor D4 and the hydraulic cylinder D6.3 respectively draw the roller on the longitudinal guide rail D6.1 and the transverse guide rail D6.2 to move to sweep the bulk material to a designated area. After the work is finished, the lifting mechanism B lifts the cleaning device D to the initial position, and the boxcar E drives away from the door frame A to finish a work cycle.
