Description

Technical Field

[0001] This invention belongs to the field of track-type conveying equipment for mining, specifically a tipping mine car system and its control method. Background Technology

[0002] Mining cars are specialized vehicles used for rail transport in mines. They are typically used to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches and are classified into five main categories based on their structure and unloading method: stationary mining cars, tipper mining cars, single-sided curved rail side-discharge mining cars, low (side) discharge mining cars, and shuttle mining cars. Most existing mining cars are pulled forward by traction ropes and lack their own power source, resulting in low integration and a lack of autonomous anti-tilt, deceleration, parking, and unloading functions. While there are now mining cars with electric control systems on the market, these integrate the anti-tilt and unloading functions into the car body. However, these functions still require electric components, leading to low operational stability and poor endurance, typically only able to operate continuously for about 3 hours, affecting efficiency and continuity. Furthermore, frequent charging increases operating costs, causing mining cars to lose their advantages of low cost and simple control. Therefore, it is necessary to develop a mining car system that can achieve anti-tilt and unloading functions using simple machinery and requires fewer electric components, and to develop a matching control method to meet practical needs.

[0083] ②The moving motor 4e controls the rotating wheel 4c to change the direction of rotation;

[0084] The specific steps for mine car deceleration control are as follows:

[0085] ① The control box sends a deceleration signal to the wireless transceiver;

[0086] ② The wireless transceiver controls the 4e mobile motor to reduce its speed;

[0087] ③ The wireless transceiver controls the brake 4f ​​to reduce the speed of the rotating wheel 4c;

[0088] ④ After the mine car 4 decelerates to the required speed or comes to a complete stop, the mine car deceleration control stops;

[0089] The specific steps for mine car parking control are as follows:

[0090] ①After the mine car comes to a complete stop, the wireless transceiver sends information to the control box;

[0091] ②The control box controls the rotary cylinder 4h to rotate via a wireless transceiver, which in turn drives the parking block 4g to rotate;

[0092] ③ Parking block 4g is in close contact with track 2 to complete the parking operation;

[0093] The specific steps for mine car convergence and track switching control are as follows:

[0094] ①When the two mine cars 4 are traveling on track 2, the wireless transceiver sends the direction information of the moving motor 4e to the control box;

[0095] ② When the control box determines that the two mine cars 4 are traveling in opposite directions, it reduces the speed of each mine car 4 by controlling the vehicle speed.

[0096] ③ When one of the mine cars 4 travels to the track-changing mechanism 3, the control box sends a signal to the wireless transceiver to execute the mine car deceleration control steps;

[0097] ④ When the mine car 4 stops on the short rail 3b, the control box sends a signal to the wireless transceiver to execute the mine car parking control procedure;

[0098] ⑤ The control box controls the rotation of the track-changing motor 3c, which moves the short rail 3b on the horizontal rail 3a through the double-layer wheel 3f and the pull rope 3e;

[0099] ⑥ After step ⑤ is completed, after another mine car 4 passes the short rail 3b, the control box controls the rail-changing motor 3c to rotate in the opposite direction, and the short rail 3b with the mine car 4 returns to the track 2.

[0100] ⑦ The control box sends a signal to the wireless transceiver to make the stopped mine car continue to move.

[0101] Furthermore, the deceleration control of the mining car includes both manual deceleration control and automatic deceleration control;

[0102] The specific steps for manual deceleration control are as follows: send a signal to the wireless transceiver through the control box or remote control to execute the mine car deceleration control steps;

[0103] The specific steps of automatic deceleration control are as follows:

[0104] ① When the mine car 4 passes the signal generator 2a, the sensor 4d receives the deceleration signal, and at this time the sensor 4d transmits the signal to the wireless transceiver.

[0105] ② The wireless transceiver sends a signal to the control box, and the control box sends a deceleration signal to the wireless transceiver;

[0106] ③ The wireless transceiver controls the mine car 4 to execute the mine car deceleration control steps;

[0107] ④ After mine car 4 stops, execute the mine car parking control procedure.

[0108] The specific working process of this invention is as follows:

[0109] First, the material is lifted from the mine shaft by the hoist 1 and placed in the car 4b. After the car is full, the control box controls the moving motor 4e to rotate, which drives the wheel 4c to move on the track 2. When the mine car 4 passes the gantry, the safety bar hits the baffle and moves backward away from the slot on the plate. After the safety mechanism is activated, the mine car 4 continues forward. When it passes the signal generator 2a, the brake 4f ​​controls the mine car 4 to decelerate. At the same time, the chuck engages with the clamp, pulling the wire rope and causing the bucket 4b to reverse, unloading the material. When it reaches the designated position, the brake 4f ​​locks the wheel, stopping the mine car 4. At this time, the bucket 4b is in the fully tilted position. Then, the controller controls the rotating cylinder 4h to rotate, lowering the parking block 4g, so that the base 4a is stably stopped on the track 2. After the tilting time is over, the control box controls the moving motor 4e to reverse, driving the mine car 4 away from the unloading area. At the same time, the bucket 4b returns to its original position using its own weight. The wire rope pulls the chuck to the position of the support plate. When passing the gantry, the baffle pushes the safety bar back to its original position, and the mine car 4 returns to the position of the inlet hoist 1.

[0110] When two mine cars 4 are traveling on track 2, the operation of a single mine car 4 is the same as described above. The main difference is that when the mine car 4 that has finished unloading is traveling towards the mine hoist 1, the mine car 4 that is fully loaded with material is approaching it. The control box is used to stop the empty mine car 4 on the short rail 3b. The parking block 4g fixes the mine car 4 to the short rail 3b. The track-changing motor 3c is turned on, and the double wheel 3f drives the pull rope 3e to move the short rail 3b from the horizontal rail 3a to the side. At this time, the fully loaded mine car 4 passes on the other short rail 3b. Then, the track-changing motor 3c is controlled again to connect the short rail 3b carrying the empty mine car 4 to track 2, and the parking block 4g is raised. The mine car then travels towards the mine hoist 1.

[0111] When an unexpected situation occurs on track 2, pressing the emergency stop button on the control box sends an emergency stop signal to the wireless transceiver. At this time, the brake 4f ​​will stop the mine car 4. After stopping, the rotating cylinder 4h controls the lowering of the parking block 4g, so that the mine car 4 stops stably on track 2.

[0112] It should be noted that you can press the button on the remote control instead of the button on the control box.

[0113] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0114] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
