Description

Technical Field

[0001] The present invention relates to the technical field of signal indicating devices, and in particular to a signal indicating device and method for an underground chute unloading chamber. Background Art

[0002] Non-coal mines will have multiple transfer and storage chutes underground. The ore mined in the mining area is transported to the transfer ore bin by transport vehicles, and the ore is unloaded into the storage chute for storage. A filter grid is installed on the top of the storage chute to filter the large pieces of ore above the grid and then fall into the storage chute after being crushed by a breaker. A crusher is installed at the bottom of the chute to crush the ore and then it is transported to the ground by a belt conveyor; or a gate valve is installed at the bottom of the chute, and the ore is loaded onto a large transport vehicle and transported to the ground.

[0003] A chute unloading chamber is excavated on one side of the main transport tunnel at the predetermined location (see Figure 1 There are 3 unloading chambers), the ore storage chute is set in the unloading chamber, and the transport vehicles enter the unloading chamber in turn to unload the ore and then go back to the mining area through the main channel.

[0004] If there are vehicles unloading ore in the unloading chamber, or the ore storage chute is full, there is too much material piled on the top grille of the ore storage chute, or the chute is under maintenance, the unloading chamber will prohibit vehicles from entering to unload ore. If a vehicle enters the unloading chamber and finds that it cannot unload ore at this time, it can only change to another unloading chamber, which is easy to cause unpredictable blockage, waste of fuel resources caused by changing chambers, and greater pollution to the mine environment due to the large amount of exhaust gas emitted by vehicles moving back and forth. It may even be impossible to unload ore due to maintenance of the chute or maintenance of equipment at the bottom of the chute, and a safety accident may occur when the transport vehicle unloads the ore into the chute. However, the transport vehicle cannot predict the above-mentioned situation in the unloading chamber in advance in the main tunnel, so the present invention sets a traffic control traffic light at the entrance of the unloading chamber, and lights a red light when the unloading chamber prohibits vehicles from entering, and lights a green light when vehicles are allowed to enter, so as to achieve the purpose of directing traffic. Summary of the invention

[0005] The technical problem to be solved by the present invention is the lack of an indicator device for the unloading construction status inside the unloading chamber.

When the signal light control unit receives any one or more signals, it determines that the chute cannot continue to unload ore, and the signal light control unit sends a red light command to the indicator light, prohibiting transport vehicles from entering the unloading chamber; when the signal light control unit does not receive any of the above signals, the system determines that the chute can unload ore, then the signal light control unit sends a green light command to the indicator light, allowing transport vehicles to enter the unloading chamber to unload.

[0011] Preferably, the method further comprises the following steps: S9. Install a detection board on the ground at the entrance of the ore unloading chamber, and the detection board is connected to the sound and light alarm arranged at the entrance of the ore unloading chamber; S10, when the transport vehicle presses the detection plate during the reversing process, the detection plate transmits a pressure signal to the signal light control unit; S11.

[0018] like Figure 1 and Figure 2 As shown, the present invention provides an underground chute unloading chamber signal indicating device, comprising a chute grille 6 arranged at the rear end of the chute unloading chamber, a visual recognition camera 1 arranged at one side of the chute grille 6 for detecting the material stacking condition of the chute grille 6, a radar level meter 2 arranged above the chute grille 6, a vehicle inspection radar 3 arranged in the chute unloading chamber, a signal light control unit 4 connected to the signals of the visual recognition camera 1, the radar level meter 2 and the vehicle inspection radar 3, and an indication signal light 5 connected to the signals of the signal light control unit 4, wherein the indication signal light 5 is arranged outside the chute unloading chamber.

[0019] The visual recognition camera 1 is used to collect the material stacking situation above the corresponding chute grille 6. The visual recognition camera 1 prepares the material stacking strategy in advance. When the visual recognition camera 1 recognizes that serious material stacking occurs above the chute grille 6, the visual recognition camera 1 will send a signal to the signal light control unit 4 that the material stacking switch is turned on.

[0020] The visual radar level meter 2 is used to collect the corresponding chute material level situation. When the material level reaches the preset full-bin value, the full-bin information is sent to the signal light control unit 4, a signal that the full-bin switch is turned on.

[0021] The vehicle detection radar 3 is used to detect whether there is a vehicle unloading ore in the corresponding unloading chamber. If a vehicle is unloading ore, a signal that a vehicle switch is turned on is sent to the signal light control unit 4.

[0022] The signal light control unit 4 is used to control the indicator light 5, and the steps are: analyzing the received information on whether there is a vehicle in the unloading chamber, the full warehouse signal of the chute and the material stacking signal above the chute grille 6, and the remote intervention signal, and judging the red or green state of the indicator light 5 according to the analysis result; when the signal light control unit 4 receives any one or more of the above signals, it is judged that the chute cannot continue to unload ore, and the signal light control unit 4 sends a red light command to the indicator light 5, and the traffic light 5 lights up the red light, prohibiting transport vehicles from entering the unloading chamber and selecting other unloading chambers to unload ore; when the signal light control unit 4 does not receive any of the above signals, the system judges that the chute can unload ore, and the signal light control unit 4 sends a green light command to the indicator light 5, and the indicator light 5 lights up the green light, allowing transport vehicles to enter the unloading chamber to unload.

[0023] The indicator light 5 receives the traffic light command from the signal light control unit 4 and lights up the traffic light to achieve the purpose of directing the transport vehicles to enter the unloading chamber in an orderly manner.

[0025] When the transport vehicle passes through the unloading chamber, it needs to reverse into the unloading chamber. If the driver does not carefully observe the indicator light 4 and the indicator light 4 is red, the detection plate 7 will be pressed down during the reversing process. The detection plate 7 transmits the pressure signal to the signal light control unit 4, and the signal light control unit 4 sends a signal to the sound and light alarm 8. After the driver receives the alarm signal from the sound and light alarm 8, he stops reversing and drives the transport vehicle out.

The sound and light alarm 8 is arranged on the side wall of the passage directly opposite to the unloading chamber, and the sound and light alarm 8 is arranged directly opposite to the unloading chamber. The driver is on the left side of the transport vehicle, and the driver can keep a close distance with the sound and light alarm 8 during the reversing process. After the sound and light alarm 8 is triggered, the driver can get the signal in the first time, avoiding the driver's failure to get the alarm signal in time due to heavy smoke and dust in the passage.

[0027] like Figure 1 As shown. A dust reduction device 9 is arranged in the middle of the unloading chamber, and the signal light control device 4 controls the connection of the dust reduction device 9. When the signal light control device 4 transmits a green light signal to the indicator light 5, the signal light control device 4 simultaneously sends a start signal to the dust reduction device 9, and the dust reduction device 9 performs dust reduction inside the unloading chamber, and does not affect the transport vehicle. When the transport vehicle is unloading in the unloading chamber, the dust reduction device 9 is turned off.
