Description

Technical Field

[0001] The invention relates to the technical field of track cleaning, in particular to a cleaning device for a track beam of a coal pit for a car. Background Art

[0002] Automobile coal receiving pit is a commonly used coal receiving facility in coking enterprises. Automobile coal receiving pit is generally composed of foundation floor, wall, platform and unloading funnel, upper plant structure (including crane beam, roof panel and column). The unloading funnel is arranged in multiple rows and columns, and track beam is arranged on the platform above the unloading funnel. When dump truck is used to load coal, the dump truck runs along the track beam to each unloading funnel and unloads coal into the corresponding unloading funnel in the upper direction. After unloading coal, a large amount of coal will be accumulated on the track beam where the car is running, which seriously affects the running of the following vehicles.

[0003] At present, the coal accumulated on the top of the track beam is usually cleaned manually, which is not only inefficient but also has a bad operating environment. Some companies use bulldozers for cleaning, but the disadvantage is that the car must be stopped to feed coal during cleaning, which seriously affects production efficiency. Summary of the invention

[0004] The present invention provides a cleaning device for track beams of a coal pit for automobiles, which can clean the track beams simultaneously during the process of an automobile exiting after unloading coal and during the next process of an automobile loading coal, without occupying the normal coal unloading operation time, and can be remotely operated, thereby effectively reducing the labor intensity of workers and improving the cleaning efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The longitudinal running trolley comprises a vehicle body and a longitudinal running mechanism consisting of longitudinal running wheels and a longitudinal running drive motor; the vehicle body is an I-shaped structure consisting of two longitudinal support beams and a transverse running beam, and longitudinal running wheels are respectively arranged at both ends of the longitudinal support beam, at least one of the longitudinal running wheels is a longitudinal running driving wheel, and the wheel axle of the longitudinal running driving wheel is connected to the output shaft of the longitudinal running drive motor.

[0008] The transverse running mechanism is composed of transverse running wheels and a transverse running drive motor; transverse running wheels are respectively arranged on both sides of the suspension rod of the cleaning mechanism, one of which is a transverse running driving wheel, and the wheel axle of the transverse running driving wheel is connected to the output shaft of the transverse running drive motor.

[0009] The sweeper consists of a rotary drive motor, a vertical shaft and rotary blades; the rotary drive motor is fixed on a suspension rod, the output shaft of the rotary drive motor is connected to the upper end of the vertical shaft, and a rotary blade is arranged at the lower end of the vertical shaft. There are multiple rotary blades, which are evenly arranged along the circumference of the vertical shaft, and the rotary blades are inclined relative to the vertical direction.

[0029] The longitudinal running trolley includes a vehicle body and a longitudinal running mechanism 6 consisting of longitudinal running wheels and a longitudinal running drive motor; the vehicle body is an I-shaped structure consisting of two longitudinal support beams and a transverse running beam 4, and longitudinal running wheels are respectively arranged at both ends of the longitudinal support beam, at least one of the longitudinal running wheels is a longitudinal running driving wheel, and the wheel axle of the longitudinal running driving wheel is connected to the output shaft of the longitudinal running drive motor.

[0030] The transverse running mechanism 7 is composed of transverse running wheels and a transverse running drive motor; transverse running wheels are respectively arranged on both sides of the suspension rod 5 of the cleaning mechanism, one of which is a transverse running driving wheel, and the wheel axle of the transverse running driving wheel is connected to the output shaft of the transverse running drive motor.

[0031] The sweeper consists of a rotary drive motor, a vertical shaft and rotary blades 8; the rotary drive motor is fixed on a suspension rod 5, the output shaft of the rotary drive motor is connected to the upper end of the vertical shaft, and a rotary blade 8 is provided at the lower end of the vertical shaft. There are multiple rotary blades 8, which are evenly arranged along the circumference of the vertical shaft, and the rotary blades 8 are inclined relative to the vertical direction.

[0032] A protective cover 9 is disposed on the upper periphery of the rotating blade 8 .

[0033] The suspension rod 5 is provided with a lifting or telescopic mechanism.

[0034] The suspension rod 5 is provided with radar probes 12 on both sides corresponding to the longitudinal running direction.

[0035] Position switches 11 are respectively arranged at both ends of the transverse running beam 4 and on the transverse running beam 4 just above the corresponding track beam 2 .

[0036] A device for cleaning the track beam of a coal pit for a car also includes a control system and a camera; the camera is installed above the track beam 2, the camera, the longitudinal running motor, the transverse running motor, the radar probe 12 and the position switch 11 are respectively connected to the control system, and the control system is also connected to a host computer.

[0037] The longitudinal running beam 3 is provided with a longitudinal running track, and the longitudinal running trolley moves along the longitudinal running track; the transverse running beam 4 is provided with a transverse running track, and the transverse running mechanism 7 moves along the transverse running track.

[0038] The longitudinal running beam 3 is arranged on the column of the upper plant structure of the coal pit for the automobile, and a longitudinal running track is arranged on the longitudinal running beam 3, and the cleaning mechanism can move longitudinally along the longitudinal running track to facilitate moving to the position that needs to be cleaned; the transverse running beam 4 is arranged on the longitudinal running trolley, and a transverse running track is arranged on the transverse running beam 4, and the cleaning mechanism can move transversely along the transverse running track to achieve switching between the working position and the waiting position. Position switches 11 (limit switches or proximity switches) are respectively arranged on the transverse running beam 4 corresponding to the working position and the waiting position, so that the cleaning mechanism can be accurately positioned.

[0039] The cleaning mechanisms are provided in two numbers, each corresponding to cleaning one track of the track beam.

[0040] The longitudinal trolley and transverse running mechanism 7 are both driven by motors. When cleaning is not required, the cleaning mechanism is in the waiting position to make way for the dump truck 13. When the track beam 2 is seriously accumulated with coal and needs to be cleaned, the longitudinal running motor is started, and the longitudinal running trolley drives the cleaning mechanism to run along the longitudinal running track to the position that needs to be cleaned, and then the transverse running motor is started, and the cleaning mechanism is moved to the working position directly above the track beam 2 through the transverse running mechanism 7. At this time, the bottom surface of the rotating blade 8 is 5 to 10 mm away from the top surface of the track beam 2, or the rotating blade 8 is lowered to a position where the bottom surface is 5 to 10 mm away from the top surface of the track beam 2 through a lifting or telescopic mechanism, and the rotary drive motor is started to drive the rotating blade 8 to rotate through the vertical shaft; the longitudinal running motor is started to move the cleaning mechanism along the track beam 2 to clean the track beam 2.

[0041] The cleaning device is provided with an active defense system, that is, radar probes 12 are respectively provided on the front and rear sides of the cleaning mechanism along the longitudinal running direction. When the distance to an obstacle (such as a dump truck 13) is close, an alarm signal is issued, and when the critical distance is reached, the movement is automatically stopped.

[0042] A camera is set at an appropriate position on the upper part of the coal pit for real-time monitoring of the working area. When the cleaning work of the track beam 2 is completed, the rotary drive motor is turned off, the transverse travel motor is started, and the cleaning mechanism is moved to the waiting position to make way for the dump truck 13.

[0043] The cleaning device of the present invention can also clean the track beam 2 in the operation area in a timely manner by remote control through a video monitoring system. The specific steps are as follows:

[0044] 1) After multiple dump trucks 13 enter the coal receiving pit, they enter their respective coal unloading positions and unload the coal into the unloading hopper 1 by back-flipping. After unloading, the dump trucks 13 drive away; during the unloading process, the scattered coal 10 accumulates on the track beam 2, affecting the passage of the dump trucks 13 behind. At this time, the operator in the central control room remotely starts the longitudinal travel motor in the cleaning device and moves the cleaning device to the position to be cleaned through the video monitoring system screen.

[0045] 2) Turn off the longitudinal running motor and start the transverse running motor. When the cleaning mechanism moves to the top of the track beam 2, the transverse running motor is stopped by the interlocking control of the position switch 11.

[0046] 3) Start the rotary drive motor on the cleaning mechanism, and then start the longitudinal running motor to drive the cleaning mechanism to move along the longitudinal running track. When the cleaning mechanism approaches the dump truck 13 entering the site later, the radar probe 12 detects and transmits the relative position data of the two. When the distance between the two reaches the set minimum distance, the longitudinal drive motor stops running. After the cleaning of this section of the track beam 2 is completed, the rotary drive motor is turned off.

[0047] 4) Start the transverse running motor, drive the cleaning mechanism to move to the waiting position, and the position switch 11 controls the alignment, and the transverse running motor stops running. The dump truck 13 entering the site later can move smoothly along the track beam 2.
