[0002] The monorail crane locomotive transport system is a single-track auxiliary transport system that travels on the top of the suspended tunnel with strong maneuverability, fast running speed, large load capacity, strong adaptability, safety and reliability. It is mainly used for the installation and withdrawal of coal mine comprehensive mining working faces. It will gradually replace the old auxiliary transport system and undertake the transportation tasks of materials, personnel, gangue, etc. in the entire mine.

[0003] At present, the existing monorail turnouts use manual pneumatic control or infrared driver control. In manual pneumatic control, the driver is often required to stop and get on and off frequently. When the locomotive stops, there will be a large impact between the locomotive and the track. Therefore, frequent stops will cause serious damage to the locomotive and the track; and frequent getting on and off increases the driver's physical burden and potential risks, which is extremely inconvenient to operate. Traditional infrared driver control is easily restricted by target distance and is easily interfered with. It has great limitations and cannot achieve true driver remote control. And when multiple locomotives pass through the turnout device, due to the lack of mandatory interlocking function and passing order, it is easy to cause lane-grabbing and collision accidents.

DETAILED DESCRIPTION

[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0023] See attached Figure 1 , attached Figure 1 A schematic diagram of the structure of a monorail turnout remote control system provided in an embodiment of the present application.

[0024] A monorail turnout remote control system provided in an embodiment of the present application is characterized in that it includes a main control box 1, a vehicle-mounted remote control 2, a track signal box group 3, a locking sensor group 4, an in-position sensor group 5, a vehicle blocking sensor group 6 and an explosion-proof solenoid valve group 7; wherein:

[0025] The main control box 1 is provided with an external enhanced antenna 8, and the main control box 1 receives the control signal sent by the vehicle remote controller 2 through the external enhanced antenna 8;

[0026] The track signal box group 3, locking sensor group 4, in-position sensor group 5, vehicle blocking sensor group 6 and explosion-proof solenoid valve group 7 are electrically connected to the main control box 1 respectively. The track signal box group 3 and explosion-proof solenoid valve 7 are used to receive control signals sent by the main control box 1, and the main control box 1 is used to receive collection signals from the locking sensor group 4, in-position sensor group 5 and vehicle blocking sensor group 6.

[0027] The main control box 1 receives the control signal sent by the vehicle remote controller 2 through the external enhanced antenna 8, that is, the vehicle remote controller 2 communicates with the main control box 1 through radio. Using radio as a signal receiving and sending method helps to increase the control distance and improve the anti-interference effect during signal transmission.

[0028] In the present application, the track signal box group 3 includes a number of track signal boxes, the locking sensor group 4 includes a number of locking sensors, the in-place sensor group 5 includes a number of in-place sensors, the vehicle blocking sensor group 6 includes a vehicle blocking sensor, and the explosion-proof solenoid valve group 7 includes a number of explosion-proof solenoid valves. The number of each of the track signal box group 3, the locking sensor group 4, the in-place sensor group 5, the vehicle blocking sensor group 6 and the explosion-proof solenoid valve group 7 is determined by the actual number of tracks. That is, the track signal box group 3, the locking sensor group 4, the in-place sensor group 5, the vehicle blocking sensor group 6 and the explosion-proof solenoid valve group 7 correspond to the number of tracks at the monorail switch. For example, when there are two tracks at the monorail switch, the number of each sensor in the track signal box group 3, the locking sensor group 4, the in-place sensor group 5, the vehicle blocking sensor group 6 and the explosion-proof solenoid valve group 7 is two, then the corresponding monorail switch remote control system is as shown in the attached Figure 2 shown.

[0029] The track signal box in the track signal box group 3 is usually suspended in the lane and has an indication function. Specifically, the sound and light signal box is used to display the switch switching status and line conditions, and the system alarm is converted into easily recognizable sound and light signals. The light signal uses red, green and yellow LED lights as signal lights, and arrow indicators are used to display the line and vehicle blocker conditions. Red indicates a fault and no passage, green indicates that the track is allowed to pass, and yellow indicates that the vehicle is passing. The single-track crane switch cannot be remotely controlled. Please wait for the vehicle to pass before performing the switch switching operation. There is a clear voice prompt when a vehicle passes.

[0030] The locking sensor group 4 and the in-place sensor group 5 are used to be set at the merging point of the monorail turnout. When the movable rail is merged with the monorail, the track is positioned and in-place, and the corresponding locking sensors and in-place sensors on the track transmit signals to the main control box 1. Specifically, the locking sensors and in-place sensors in the locking sensor group 4 and the in-place sensor group 5 are set in the locking actuator and the track change actuator, collect corresponding status information, and transmit it to the PLC programmable controller for judgment, and output signals such as permission to pass, prohibition of passage, error, etc. The corresponding signals are converted into corresponding sound and light signals through the display.

[0031] In order to increase the safety distance and safety factor, a heavy-duty car blocker is set between the tunnel roof and the overhead rail. Usually, the heavy-duty car blocker has a fixed base fixed between the tunnel roof and the overhead rail by a fixed anchor rod. The car blocker sensor in the car blocker sensor group 6 is set at the heavy-duty car blocker on the track, which is used to monitor the use status of the heavy-duty car blocker, transmit it to the PLC programmable controller, perform logic processing, and output signals such as allowing passage and prohibiting passage, which are converted into corresponding light signals through the display to provide information for the driver to pass, stop and wait, etc.

[0032] When the main control box 1 performs track unlocking and switch switching operations, it controls the corresponding solenoid valves in the explosion-proof solenoid valve group 7 to act, controls the on-off of the air circuit, and further controls the air cylinder actuator to perform the operation.

[0033] The monorail turnout remote control system provided by the present application, the vehicle-mounted remote controller 2 sends a control signal to the main control box 1, and after receiving the control signal, the main control box 1 performs logic control according to the signals of the locking sensor group 4, the in-position sensor group 5 and the vehicle blocking sensor group 6 monitored by it, and sends the logic control command to the track signal box group 3 and the explosion-proof electromagnetic valve group 7 to perform warning reminders and unlocking and turnout switching operations. Therefore, the monorail turnout remote control system provided by the present application makes the control of the monorail turnout safer and more convenient.

[0034] As attached Figure 3 As shown, in the remote control system for the monorail turnout provided in the embodiment of the present application, the main control box 1 includes a PLC programmable controller 101, a relay 102, a signal acquisition component 103 and an antenna receiving device 104. The antenna receiving device 104 is electrically connected to the external reinforced antenna 8, the antenna receiving device 104 is electrically connected to the signal acquisition component 103, the track signal box group 3, the locking sensor group 4, the in-position sensor group 5 and the vehicle blocking sensor group 6 are electrically connected to the signal acquisition component 103, the signal acquisition component 103 is electrically connected to the PLC programmable controller 101, the input end of the relay 102 is connected to the PLC programmable controller 101, and the output end of the relay 102 is connected to the explosion-proof solenoid valve group 7.

[0035] The vehicle remote control 2 sends a control signal to the main control box, the external enhanced antenna 8 receives the control signal and transmits it to the antenna receiving device 104, which is initially processed by the antenna receiving device 104 and then transmitted to the signal acquisition component 103, and finally transmitted to the PLC programmable controller 101 through the signal acquisition component 103.

[0036] The signals collected by the track signal box group 3, the locking sensor group 4, the in-position sensor group 5 and the vehicle blocking sensor group 6 are transmitted to the signal acquisition component 103, and after being processed by the signal acquisition component 103, are transmitted to the PLC programmable controller 101 for logic control.

[0037] The PLC programmable controller 101 transmits the logic control instruction to the relay 102, and the relay 102 controls the on and off of the coil of the corresponding explosion-proof solenoid valve in the explosion-proof solenoid valve group 7, thereby controlling the on and off of the air circuit to control the extension and retraction action of the air cylinder actuator, thereby performing unlocking and switch switching operations.

[0038] In the embodiment of the present application, the main control box 1 further includes a PLC expansion module 105, and the PLC expansion module 105 is connected to the PLC programmable controller 101. The PLC expansion module 105 can realize the logic control upgrade according to the actual needs on site.

[0039] In an embodiment of the present application, the main control box also includes a 24V power supply component 106, and the 24V power supply component 106 provides 24V power for the PLC programmable controller 101, relay 102, signal acquisition component 103, antenna receiving device 104 and PLC expansion module.

[0040] In the embodiment of the present application, the locking sensor group 4, the in-position sensor group 5 and the blocking sensor group 6 all include proximity switches. Optionally, the locking sensor group 4, the in-position sensor group 5 and the blocking sensor group 6 are all composed of proximity switches. A proximity switch is a position switch that does not require direct mechanical contact with moving parts for operation. When an object approaches the switch sensing surface to the action distance, the switch can be activated, thereby driving a DC appliance or providing control instructions to a computer device. A proximity switch is a switch-type sensor (i.e., a contactless switch). It has the characteristics of a travel switch and a micro switch, and has sensing performance, reliable operation, stable performance, fast frequency response, long service life, strong anti-interference ability, etc., and has the characteristics of being waterproof and corrosion-resistant. Therefore, it is more suitable for the embodiment of the present application.

[0041] In the embodiment of the present application, the locking sensor group 4, the in-position sensor group 5, the vehicle blocking sensor group 6 and the explosion-proof solenoid valve group 7 are electrically connected to the main control box 1 through the junction box 9. In the specific implementation of the present application, an intrinsically safe junction box can be selected. Specifically, the locking sensor group 4, the in-position sensor group 5, the vehicle blocking sensor group 6 and the explosion-proof solenoid valve group 7 are respectively provided with an intrinsically safe junction box, and the main control box 1 is connected through the intrinsically safe junction box.

[0042] In an embodiment of the present application, when two or more vehicles are about to pass through the track-aligning device, a first-come-first-served priority operation is implemented, and the later-arriving locomotive has no right to operate the monorail switch for switch switching before the locomotive has completely passed through the track-aligning device, and the corresponding track signal box sends out a waiting sound and light signal to prompt the driver to stop and wait.

[0043] For example, when locomotives A and B are both going to pass through the monorail switch, the identification sensor determines the order of precedence. Locomotive A, which arrives first, has the right to control the monorail switch. Even if locomotive B, which arrives later, issues a command to control the monorail switch to switch, the PLC programmable controller refuses to execute the switch switching procedure, which is an invalid operation. At the same time, the signal box on track B will issue a voice message "The vehicle has passed, please stop and wait", and the yellow waiting signal light will light up, prompting the driver of locomotive B to stop and wait. When locomotive A has completely passed the monorail switch, the signal box on track B will issue a voice message "The vehicle has passed, and the switch can be switched", and the green permission signal light will light up, prompting the driver of locomotive B to resume the control of the monorail switch and perform the switch switching operation.

[0044] The monorail crane turnout remote control system provided in the embodiment of the present application ensures the personal safety of operators, reduces staffing, reduces the physical burden of workers, improves the efficiency of monorail crane locomotives passing through the track alignment device, adopts one-button operation, reduces operating requirements, and improves usage efficiency.
