Description

Technical Field

[0001] The invention relates to a device for cleaning, lifting and conveying excess coal in an open wagon, which is an automated mechanical equipment for cleaning and lifting excess coal in an open wagon of a railway. Background Art

[0002] With the development of open car cleaning technology, how to quickly and efficiently transport the collected residual coal to the designated location after the cleaning device cleans the bottom and side walls of the car has become an urgent problem to be solved by current technology. The traditional residual coal cleaning device requires the side door of the open car to be opened, and the cleaned residual coal is discharged from the side door. After discharge, it is cleaned or transported. This method is not only inefficient, but also requires a lot of manpower, which increases the cleaning cost. At the same time, the cumbersome process of opening and closing the side door of the open car also affects the speed of the entire cleaning process. In addition, the traditional residual coal cleaning device often generates a large amount of dust during the cleaning process, which has a certain impact on the environment and the health of the operators. Therefore, it is particularly important to develop an open car residual coal cleaning, lifting and conveying device that can quickly and efficiently transport residual coal while reducing manpower participation and dust pollution. Summary of the invention

[0003] In view of the above-mentioned defects or shortcomings in the prior art, the present invention provides a device for cleaning, lifting and conveying excess coal in an open car.

[0004] The object of the present invention is achieved in that: The lower sprocket of the lower sprocket is connected with the upper sprocket of the frame by the lifting arm, and the lower sprocket of the lower sprocket is connected with the upper sprocket of the frame by the lifting arm.

[0005] A further solution is: the lifting arm is fixed on a walking platform, and the walking platform moves along a guide rail arranged on the platform through driving rollers.

[0006] A further solution is that the residual coal in the carriage is collected in a collecting tray with a groove, and the dustpan-type coal hopper scoops up the residual coal from the collecting tray and transports it out.

[0007] The further scheme is that: the chute pipe includes a transition chute pipe and a length-adjustable flexible telescopic pipe. The transition chute pipe obliquely extends out of the frame and is hermetically connected to the telescopic pipe. The telescopic pipe telescopically extends vertically downward, and the outlet of the telescopic pipe is connected to the coal feeder belt.

[0008] The further scheme is that: the two lower sprockets are horizontally opened, wherein: the lower sprocket and the upper sprocket on the ascending side of the chain are arranged perpendicular to the ground.

[0009] The further scheme is that: the horizontally opened distance between the two lower sprockets is at least the length of a hopper-type coal bucket, so that when the hopper-type coal bucket moves from one side sprocket to the other side sprocket among the two lower sprockets, the coal can be fully shoveled into the coal bucket.

[0010] The further scheme is that: the two lower sprockets are arranged on an adjustable bracket. The adjustable bracket includes cross beam slide rails respectively arranged at both ends of the lower side of the frame. The bearing seats of the two lower sprockets are respectively fixed on the cross beam slide rails through elastic telescopic piston arms in a horizontally slidable manner. A spring is arranged between the two elastic telescopic piston arms. When the hopper-type coal bucket moves horizontally forward to shovel coal and encounters obstacles of coal blocks, the two lower sprockets drive the hopper-type coal bucket to shake up and down and back and forth through the elastic telescopic piston arms and the spring to help shovel the remaining coal into the hopper-type coal bucket.

[0011] The further scheme is that: coal raking wheels and coal sweeping wheels are respectively arranged at both ends of the outer side of the lower end of the frame. The coal raking wheels and the coal sweeping wheels are used to assist in collecting the remaining coal to the coal shoveling area of the hopper-type coal bucket.

[0012] The further scheme is that: a dust-proof shield is arranged on the outer side of the coal bucket lifting frame.

[0013] The beneficial effects of the present invention are as follows: (1) Solve the problem of the real-time collection of the remaining coal after the railway open wagon is cleared and the rapid and efficient transportation to the designated position.

[0014] (2) Solve the problem that the traditional method for cleaning the remaining coal requires opening and closing the side door of the open wagon. The present invention can realize the rapid collection, lifting and transportation of the remaining coal without opening the side door of the open wagon, simplifies the operation process, improves the cleaning speed, and has the advantages of convenient operation, high efficiency, energy conservation and environmental protection.

[0015] (3) Solve the problem of dust pollution in the cleaning process of the traditional method for cleaning the remaining coal. The present invention effectively reduces the generation and diffusion of dust through the adopted sealed transportation method, is environmentally friendly and efficient, can ensure that the remaining coal in the open wagon is timely, rapidly, environmentally friendly and efficiently transported to the predetermined position, and significantly saves human resources.

DETAILED DESCRIPTION

[0018] A device for cleaning, lifting and conveying excess coal in an open car, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the open car residual coal cleaning, lifting and conveying device includes a coal unloading platform 1, which is a steel frame structure across the rails. The coal transport train open car 2 passes under the platform to unload coal. A coal hopper lifting frame 3 is arranged on the platform. The coal hopper lifting frame 3 is driven by a lifting arm 4 to move in and out of the carriage of the open car 2. The lifting arm 4 is fixed on a walking platform 5. The walking platform 5 is positioned to cover the coal hopper lifting frame 3. The walking platform 5 moves along the guide rail 101 arranged on the platform 1 through a driving roller 501 driven by a driving motor to clean the residual coal left in the carriage of the open car 2. The lifting arm 4 includes a wire rope 401, an upper hanging wheel 402 and a lower hanging wheel 403 arranged on both sides of the lifting arm 4 column. The upper hanging wheel 402 is hung on the lifting arm 4 column, and the lower hanging wheel 403 is connected and fixed to the lower end of the coal bucket lifting frame 3. The wire rope 401 passes through the upper hanging wheel 402 and the lower hanging wheel 403 to connect to the lifting motor 404. The lifting motor 404 drives the wire rope 401 to lift or lower the coal bucket lifting frame 3 through the upper hanging wheel 402 and the lower hanging wheel 403. There are two sets of upper sprocket wheels 301 and lower sprocket wheels 302 arranged at intervals in the coal hopper lifting frame 3. The upper sprocket wheel 301 is on the upper end side of the coal hopper lifting frame 3, and the lower sprocket wheel 302 is on the lower end side of the coal hopper lifting frame 3. Annular chains 303 are respectively mounted on the two sets of upper sprocket wheels 301 and lower sprocket wheels 302. Dustpan-type coal hoppers 304 are fixed on the two annular chains 303 in sequence and at intervals. The two annular chains drive the coal hopper 304 to move up and down through the synchronous rotation of the upper sprocket wheel 301 and the lower sprocket wheel 302 to shovel the concentrated excess coal in the carriage of the open car 2 and transport it out. Figure 1 and Figure 4As shown, there are at least two lower sprockets in each group of upper sprockets 301 and lower sprockets 302. The two lower sprockets 302 are horizontally opened forward and backward and correspond to one upper sprocket 301. A chute 6 is provided at the upper end of the coal hopper lifting frame 3. The upper port of the chute 6 is connected to the scoop-shaped coal hopper 304 that has been flipped from the upper sprocket. The lower port of the chute 6 is connected to the coal feeder 7. The chute 6 is used to send the remaining coal collected from the scoop-shaped coal hopper into the coal feeder 7. The coal feeder 7 is also arranged on the walking platform 5. The conveyor belt 701 of the coal feeder 7 is connected to the coal conveyor belt 8 arranged on the ground.

[0019] For the convenience of shoveling, the remaining coal is concentrated in a collecting tray 9 with grooves. And, coal raking wheels 10 and coal sweeping wheels 11 are respectively arranged at both ends of the outer side of the lower end of the coal hopper lifting frame 3. The coal raking wheels and the coal sweeping wheels are used to assist in collecting the remaining coal to the coal shoveling area of the scoop-shaped coal hopper, such as the collecting tray 9. The scoop-shaped coal hopper 304 shovels up the remaining coal from the collecting tray and transports it out.

[0020] In the embodiment: The chute 6 includes a transition chute 601 and an adjustable-length flexible telescopic tube 602. The transition chute obliquely extends out of the coal hopper lifting frame 3 and is hermetically connected to the telescopic tube 602. The telescopic tube 602 telescopically extends vertically downward, and the outlet of the telescopic tube 602 is connected to the coal feeder belt.

[0021] In the embodiment: The two lower sprockets 302 are horizontally opened forward and backward. Among them, the lower sprocket and the upper sprocket 301 on the ascending side of the chain are arranged perpendicular to the ground. And, the horizontally opened distance of the two lower sprockets is at least the length of a scoop-shaped coal hopper, so that the scoop-shaped coal hopper can fully shovel the coal when moving from one side sprocket to the other side sprocket among the two lower sprockets into the scoop-shaped coal hopper 304.

[0022] During the process of shoveling coal with the skip-type coal hopper 304, jamming of small coal lumps may occur, sometimes causing the coal-shoveling failure and shutdown for adjustment. To solve this problem, in this embodiment, the two lower sprockets 302 are arranged on an automatically adjustable bracket. The adjustable bracket includes cross beams 305 respectively arranged at both ends of the lower side of the coal hopper lifting frame 3. The bearing seats of the two lower sprockets 302 are respectively fixed on the cross beam 305 through elastic telescopic piston arms 306 so as to be laterally slidable. The up-and-down telescoping of the elastic telescopic piston arms 306 can be in the form of an oil cylinder or realized by a spring as shown in the figure. The sliding is realized by arranging slide rails on the cross beam 305, and the elastic telescopic piston arms 306 realize left-and-right lateral sliding through the slide rails. A spring 307 is arranged between the two elastic telescopic piston arms 306. When the skip-type coal hopper 304 moves horizontally forward to shovel coal and encounters coal block obstacles, the two lower sprockets 302 drive the skip-type coal hopper to shake up and down and back and forth through the elastic telescopic piston arms 306 and the elastic tension springs 307 to help shovel the remaining coal into the skip-type coal hopper. The amplitude of the up-and-down telescoping of the elastic telescopic piston arms 306 is not greater than 100 mm. When contracting upward, the chain will become slack. At this time, the spring 307 will open to pull the distance between the two lower sprockets 302 to keep the tightness of the chain 301. By adjusting the downward thrust of the elastic telescopic piston arms 306 to be greater than the external elastic force of the spring 307, the balance between the opening and stretching of the chain can be ensured, forming a shake when the skip-type coal hopper 304 moves horizontally forward to shovel coal and encounters coal block obstacles to help shovel the remaining coal into the skip-type coal hopper.

[0023] To prevent coal dust from flying: A dust-proof cover plate is arranged outside the coal hopper lifting frame 3.

[0024] The above embodiment solves the problem of real-time collection of the remaining coal after the railway gondola car is cleared and quickly and efficiently transporting it to the designated position. It solves the problem that the traditional method of clearing the remaining coal requires opening and closing the side door of the gondola car, can realize the rapid collection, lifting and transportation of the remaining coal, simplifies the operation process, improves the cleaning speed, and has the advantages of convenient operation, high efficiency, energy conservation and environmental protection. It solves the problem of dust pollution in the traditional method of clearing the remaining coal during the cleaning process.
