The upper end of the connecting rope is connected to the fall trigger rope through a hook, which is convenient to quickly establish the connection between the connecting rope and the fall trigger rope by means of hanging. At the same time, it is also convenient to quickly separate the two. By fixedly installing a waistband hook on the main body of the man-riding vehicle, it is convenient to provide a hanging fulcrum for the safety waistband when the safety waistband is in an idle state. By fixedly connecting a fixing rod to the upper end of the support box body, it is convenient to use the fixing rod to fixedly install the emergency power-off device on the top of the roadway. A guiding bracket is fixedly connected to the lower part of the support box body. At the same time, a sliding box body is vertically slidably connected to the guiding bracket, so that the sliding box body has a certain sliding stroke relative to the support box body. A limiting frame is arranged at the lower end of the guiding bracket, which is convenient to use the limiting frame to limit the downward sliding stroke of the sliding box body and prevent the sliding box body from separating from the guiding bracket. Four sliders that are slidably matched with the four guide rails are arranged inside the sliding box body, which can make the sliding process between the sliding box body and the guiding bracket more stable and improve the overall reliability. A rope supporting wheel is rotatably connected to the rear side of the sliding box body. At the same time, the rope supporting wheel is connected to the fall trigger rope suspended below the cable.

At the same time, an operating body is fixedly connected to the upper end of the trigger rod, and a trigger rod return spring is arranged between the operating body and the bottom plate of the support box body. The elastic force of the trigger rod return spring can be used to effectively support the weight of the trigger rod and the sliding box body, so that after the normal state or the fall event is processed, the sliding box body can be kept at the set height position of the guiding bracket. An L-shaped pressing plate is formed on the right side of the operating body. At the same time, the moving reed is rotatably connected to the support box body, and the left reed on it is located below the L-shaped pressing plate and is connected to the L-shaped pressing plate through a moving reed return spring. When the sliding box body moves downward, the left reed can be pressed by the L-shaped pressing plate, and then the right end of the right reed can swing upward.The normally open contact piece and the normally closed contact piece are respectively arranged in the upward swing path and the downward swing path of the right reed piece, and the normally open contact and the normally closed contact are respectively connected to the normally open contact piece and the normally closed contact piece. At the same time, a moving reed piece contact is installed at the right end of the right reed piece. Under normal conditions, the moving reed piece contact can be kept in contact with the normally closed contact, and when a drop occurs, the moving reed piece contact can be kept in contact with the normally open contact. On this basis, by connecting the first pair of input terminals of the controller to the moving reed piece contact and the normally open contact, it is possible to effectively detect whether a drop event occurs. At the same time, by connecting the controller to the control switch on the power supply circuit of the man-riding vehicle, the power supply of the man-riding vehicle can be timely controlled to be disconnected when a drop event occurs. Thus, the personal safety of pedestrians can be effectively ensured.

[0034] The device has a simple structure and low manufacturing cost. It can intelligently detect whether a drop condition occurs, can effectively cope with the situation of passengers dropping due to floor heave during the operation of the man-riding vehicle, and can automatically cut off the power supply of the man-riding vehicle when a drop occurs. Furthermore, it can effectively avoid secondary injuries caused by pedestrians being dragged and subsequent vehicles colliding, effectively ensure the safe transportation of the man-riding vehicle, protect the lives of miners, reduce the operation and management difficulty of the man-riding vehicle, and ensure the safe production operation of the mine.

[0035] The present invention also provides a method for intelligent braking of a man-riding vehicle for pedestrians dropping in an inclined shaft, which adopts an intelligent braking device for a man-riding vehicle for pedestrians dropping in an inclined shaft, and includes the following steps:

[0036] Step 1: Arrange emergency power-off devices along the length direction of the cable in the inclined shaft in sequence, and fixedly install the emergency power-off devices on the top of the roadway through fixing rods. Then, arrange the drop trigger rope on the rope support wheels of the corresponding emergency power-off devices, and hang the hook on the drop trigger rope;

[0037] At the same time, establish a communication connection between the controller and the control terminal in the master control room through the communication module;

[0038] Step 2: When a pedestrian is sitting on the passenger seat, take off the safety belt, open the buckle, adjust the belt length to a suitable length, and then buckle it on the waist; control the control switch on the power supply circuit of the man-riding vehicle to close to make the man-riding vehicle operate normally;

[0039] During the normal operation of the man-riding vehicle, when a pedestrian falls from the passenger seat, the safety belt and the connecting rope pull down the falling trigger rope, thereby pressing down the rope-supporting pulley and driving the sliding box to slide downward along the guiding bracket. During the sliding process, the trigger rod overcomes the elastic force of the trigger rod return spring and drives the operating body to press down the left reed, causing the moving reed to rotate around the rotation center of the moving reed rotating shaft. During the rotation process, the moving reed contact on the right reed separates from the normally closed contact and contacts the normally open contact. At this time, the energized circuit between the first pair of input terminals of the controller is connected by the mutually contacting moving reed contact and the normally open contact. After the energized circuit between the first pair of input terminals of the controller is connected, the controller controls the sound and light alarm to give a sound and light warning to remind the relevant management personnel of a pedestrian falling accident. At the same time, the controller controls the control switch on the power supply circuit of the man-riding vehicle to disconnect, so that the man-riding vehicle stops running;

[0040] Step 3: After the pedestrian falling accident is handled, the pedestrian sits on the passenger seat again, and the downward pulling force disappears. Under the elastic force of the trigger rod return spring, the sliding box is driven by the operating body and the trigger rod to reset to the normal position. At the same time, the left reed is pulled upward by the moving reed return spring. During the swinging process, the moving reed contact separates from the normally open contact and contacts the normally closed contact. At this time, the energized circuit between the first pair of input terminals of the controller is disconnected by the mutually separated moving reed contact and the normally open contact. After the energized circuit between the first pair of input terminals of the controller is disconnected, the controller controls the sound and light alarm to stop operating. At the same time, the controller controls the electric telescopic rod to perform three intermittent telescopic cycle actions within the set detection period. During each telescopic cycle action, first, the sliding box is pushed downward, and then, under the elastic force of the trigger rod return spring, the sliding box is reset to move upward, and a contact occurs between the self-checking contact and the detection contact. At the same time, the energized circuit between the second pair of input terminals of the controller is connected by the self-checking contact and the detection contact in the contact state, forming an effective self-checking process. Within the set detection period, when the controller receives that the effective self-checking process is equal to 3 times, it generates an effective unlocking signal and sends it to the control terminal in the main control room through the communication module. After receiving the effective unlocking signal, the control terminal controls the control switch on the power supply circuit of the man-riding vehicle to close, so that the man-riding vehicle runs normally again. Within the set detection period, when the controller receives that the effective self-checking process is less than 3 times, it generates a fault signal and sends it to the control terminal in the main control room through the communication module. The control terminal locates the fault position according to the number of the emergency power-off device that sends the fault signal and generates a fault report form, so that the relevant management personnel can handle the fault in time according to the fault report form.

[0041] In the present invention, when a pedestrian accidentally falls due to bumping into the bottom drum of the monkey car, the sliding box body can drive the trigger rod and the operating body to move downward, thereby pressing down the left reed of the moving reed, and then enabling the right reed to swing upward, and making the contact of the moving reed contact the normally open contact. As a result, the controller can receive the falling signal, and then can timely disconnect the control switch on the power supply circuit of the monkey car, so that the monkey car stops running in time, and can remind the nearby operators to handle the falling incident in time by sending out an alarm, so as to effectively avoid secondary injuries such as the pedestrian being dragged and collided by the following vehicle, and effectively protect the life safety of the pedestrian. After the falling incident is handled, the state of the emergency power-off device at the location is detected through three intermittent telescopic cyclic actions of the electric telescopic rod within the set detection period, which can provide a reliable guarantee for the safe and stable operation of the subsequent monkey car.

[0042] The implementation process of this method is simple and has a high degree of intelligence. It can automatically handle the pedestrian falling accident during operation and can effectively protect the life safety of pedestrians. Brief Description of the Drawings

[0085] In the present invention, by fixedly installing a plurality of rope guide rings on the main body of the man-riding vehicle, it is convenient to use the plurality of rope guide rings to limit the connecting rope, and it can avoid the displacement of the connecting rope during the operation of the man-riding vehicle, effectively ensuring that when a person falls, the connecting rope can effectively act on the fall trigger rope. The upper end of the connecting rope is connected to the fall trigger rope through a hook, which is convenient to quickly establish the connection between the connecting rope and the fall trigger rope by means of hanging. At the same time, it is also convenient to quickly realize the disconnection between the two. By fixedly installing a belt hook on the main body of the man-riding vehicle, it is convenient to provide a hanging fulcrum for the safety belt when the safety belt is in an idle state. By fixedly connecting a fixing rod to the upper end of the support box body, it is convenient to use the fixing rod to fixedly install the emergency power-off device on the top of the roadway. A guiding support is fixedly connected to the lower part of the support box body. At the same time, a sliding box body is vertically slidably connected to the guiding support, so that the sliding box body has a certain sliding stroke relative to the support box body. A limiting frame is arranged at the lower end of the guiding support, which is convenient to use the limiting frame to limit the downward sliding stroke of the sliding box body and prevent the sliding box body from separating from the guiding support. Four sliders that are slidably matched with four guide rails are arranged inside the sliding box body, which can make the sliding process between the sliding box body and the guiding support more stable and improve the overall reliability. A rope supporting wheel is rotatably connected to the rear side of the sliding box body. At the same time, the rope supporting wheel is connected to the fall trigger rope suspended below the cable. That is, in the normal state, the fall trigger rope can be supported by the rope supporting wheel, and when a fall occurs, the fall trigger rope can be used to drive the sliding box body to slide downward, thereby being able to timely trigger the emergency protection measures after the fall. A trigger rod is fixedly connected to the upper end of the sliding box body, and the trigger rod extends into the interior of the support box body through a through hole in the bottom plate of the support box body. At the same time, an operating body is fixedly connected to the upper end of the trigger rod, and a trigger rod return spring is arranged between the operating body and the bottom plate of the support box body. The elastic force of the trigger rod return spring can be used to effectively support the weight of the trigger rod and the sliding box body, so that after the normal state or the fall event is processed, the sliding box body can be kept at the set height position of the guiding support. An L-shaped pressing plate is formed on the right side of the operating body. At the same time, a moving reed is rotatably connected to the support box body, and the left reed on it is located below the L-shaped pressing plate and is connected to the L-shaped pressing plate through a moving reed return spring. When the sliding box body moves downward, the left reed can be pressed by the L-shaped pressing plate, so that the right end of the right reed swings upward.The normally open contact piece and the normally closed contact piece are respectively arranged in the upward swing path and the downward swing path of the right reed piece, and the normally open contact and the normally closed contact are respectively connected to the normally open contact piece and the normally closed contact piece. At the same time, a moving reed piece contact is installed at the right end of the right reed piece, so that the moving reed piece contact can be kept in contact with the normally closed contact under normal conditions, and when a drop occurs, the moving reed piece contact can be kept in contact with the normally open contact. On this basis, by connecting the first pair of input ends of the controller to the moving reed piece contact and the normally open contact, whether a drop event occurs can be effectively detected. At the same time, by connecting the controller to the control switch on the power supply circuit of the manriding vehicle, the power supply of the manriding vehicle can be timely controlled to be disconnected when a drop event occurs. Thus, the personal safety of pedestrians can be effectively ensured.

[0086] The device has a simple structure and low manufacturing cost. It can intelligently detect whether a drop condition occurs, can effectively deal with the situation of passengers falling due to floor heave during the operation of the manriding vehicle, and can automatically disconnect the power supply of the manriding vehicle when a drop occurs. Furthermore, it can effectively avoid secondary injuries caused by pedestrians being dragged and subsequent vehicles colliding, effectively ensure the safe transportation of the manriding vehicle, protect the lives of miners, reduce the operation and management difficulty of the manriding vehicle, and ensure the safe production operation of the mine.

[0087] The present invention also provides a method for intelligent braking of a manriding vehicle for pedestrians falling in an inclined shaft, which adopts an intelligent braking device for a manriding vehicle for pedestrians falling in an inclined shaft, and includes the following steps:

[0088] Step 1: Arrange emergency power-off devices 12 along the length direction of the cable 1 in the inclined shaft in sequence, fixedly install the emergency power-off devices 12 on the top of the roadway through fixing rods 13, and arrange the drop trigger rope 2 on the rope supporting wheels 16 of the corresponding emergency power-off devices 12, and hang the hook 7 on the drop trigger rope 2;

[0089] At the same time, establish a communication connection between the controller and the control terminal in the master control room through the communication module;

[0090] Step 2: When a pedestrian is sitting on the passenger seat 4, take off the safety belt 10, open the buckle 11, adjust the belt length to a suitable length, and then buckle it on the waist; control the control switch on the power supply circuit of the manriding vehicle to be closed to make the manriding vehicle run normally;

[0091] During the normal operation of the man-riding device, when a pedestrian falls from the passenger seat 4, the falling trigger rope 2 is pulled downward through the safety belt 10 and the connecting rope 8, thereby pressing down the rope supporting wheel 16 and driving the sliding box body 17 to slide downward along the guiding bracket 18. During the sliding process, the trigger rod 15 overcomes the elastic force of the trigger rod return spring 24 and drives the operating body 23 to press down the left reed 27, causing the moving reed 26 to rotate around the rotation center of the moving reed rotating shaft 25. During the rotation process, the moving reed contact 31 on the right reed 28 disengages from the normally closed contact 37 and contacts the normally open contact 36. At this time, the energized circuit between the first pair of input terminals of the controller is connected by the mutually contacting moving reed contact 31 and the normally open contact 36. After the energized circuit between the first pair of input terminals of the controller is connected, the controller controls the sound and light alarm 14 to give a sound and light warning to remind the relevant management personnel of a pedestrian falling accident. At the same time, the controller controls the control switch on the power supply circuit of the man-riding device to disconnect, so that the man-riding device stops running;

[0092] Step 3: After the pedestrian fall accident is handled, the pedestrian sits on the passenger seat 4 again, and the downward pulling force disappears. Under the elastic force of the trigger rod return spring 24, the sliding box body 17 is driven by the operating body 23 and the trigger rod 15 to reset to the normal position. At the same time, the left reed 27 is pulled by the moving reed return spring 29 to swing upward. During the swinging process, the moving reed contact 31 is separated from the normally open contact 36 and contacts the normally closed contact 37. At this time, the energized circuit between the first pair of input terminals of the controller is disconnected by the separated moving reed contact 31 and the normally open contact 36. After the energized circuit between the first pair of input terminals of the controller is disconnected, the controller controls the sound and light alarm 14 to stop operating. At the same time, the controller controls the electric telescopic rod 19 to perform three intermittent telescopic cycle actions within the set detection period. During each telescopic cycle action, first, the sliding box body 17 is pushed downward, and then, under the elastic force of the trigger rod return spring 24, the sliding box body 17 is reset to move upward, and a contact occurs between the self-checking contact 38 and the detection contact 40 (when the electric telescopic rod 19 is fully extended, the sliding box body 17 is pushed downward by a set distance, and at the same time, the trigger rod 15 is driven to move downward by a set distance, thereby pressing the left reed 27 of the moving reed 26 downward by a certain angle through the operating body 23, and synchronously driving the right reed 28 to rotate upward by a certain angle. When the right reed 28 rotates to the maximum angle state, the self-checking contact 38 just contacts the detection contact 40). At the same time, the energized circuit between the second pair of input terminals of the controller is connected by the contacting self-checking contact 38 and the detection contact 40, forming an effective self-checking process. Within the set detection period, when the controller receives that the number of effective self-checking processes is equal to 3 times, an effective unlocking signal is generated and sent to the control terminal in the main control room through the communication module. After receiving the effective unlocking signal, the control terminal controls the control switch on the power supply circuit of the monkey car to close, so that the monkey car runs normally again. Within the set detection period, when the controller receives that the number of effective self-checking processes is less than 3 times, a fault signal is generated and sent to the control terminal in the main control room through the communication module. The control terminal locates the fault position according to the number of the emergency power-off device 12 that issues the fault signal and generates a fault report form, so that the relevant management personnel can timely handle the fault according to the fault report form.

[0093] As an optimization, during the process of controlling the electric telescopic rod 19 to perform three intermittent telescopic cycle actions within the set detection period, the pressure sensor on the electric telescopic rod 19 is used to collect the pressure signal during the extension of the telescopic part of the electric telescopic rod 19 in real time and send it to the controller. The controller obtains the resistance data according to the pressure signal, and the controller judges the resistance situation between the slider and the guide rail 21 according to the resistance data. When the resistance data is greater than 40N, a lubrication alarm signal is generated, and the sound and light alarm 14 is controlled to give a lubrication alarm reminder, so that the relevant personnel can timely add lubricating oil to the slider.

[0094] In the present invention, when a pedestrian accidentally falls due to bumping against the bottom drum of the monkey truck, the sliding box body can drive the trigger rod and the operating body to move downward, thereby pressing the left reed of the moving reed, and further enabling the right reed to swing upward, and making the contact of the moving reed contact the normally open contact, so that the controller can receive the falling signal, and then can timely disconnect the control switch on the power supply circuit of the monkey truck, stop the operation of the monkey truck in time, and can remind the nearby operators to dispose of the falling incident in time by sending out an alarm, so as to effectively avoid secondary injuries such as the pedestrian being dragged and collided by the following vehicle, and effectively protect the life safety of the pedestrian. After the falling incident is handled, the state of the emergency power-off device at the location is detected through three intermittent telescopic cycle actions of the electric telescopic rod within the set detection period, which can provide a reliable guarantee for the safe and stable operation of the subsequent monkey truck.

[0095] The implementation process of this method is simple and has a high degree of intelligence. It can automatically handle the pedestrian falling accident during operation and effectively protect the life safety of pedestrians.

At the same time, the left spring (27) is pulled upward by the movable spring return spring (29). During the swinging process, the movable spring contact (31) is separated from the normally open contact (36) and contacts the normally closed contact (37). At this time, The movable spring contact (31) and the normally open contact (36) that are separated from each other disconnect the power circuit between the first pair of input terminals of the controller. After the power circuit between the first pair of input terminals is disconnected, the controller controls the sound and light alarm (14) to stop operating. At the same time, the electric telescopic rod (19) is controlled to perform three intermittent telescopic cycles within a set detection period. During each telescopic cycle, the sliding box (17) is first pushed downward, and then the trigger rod return spring (24) is used to return the box to the original position. The sliding box (17) is reset to move upward, and during each telescopic cycle, a contact occurs between the self-test contact (38) and the detection contact (40). At the same time, the self-test contact (38) and the detection contact (40) in the contact state are connected to the power-on circuit between the second pair of input terminals of the controller, forming an effective self-test process. Within the set detection cycle, when the controller receives the effective self-test process equal to 3 times, it generates an effective unlocking signal, and sends it to the control terminal in the main control room through the communication module. After receiving the effective unlocking signal, the control terminal controls the control switch on the monkey car power supply circuit to close, so that the monkey car resumes normal operation. Within the set detection cycle, when the controller receives the effective self-test process less than 3 times, it generates a fault signal, and sends it to the control terminal in the main control room through the communication module. The control terminal locates the fault position according to the number of the emergency power-off device (12) that sends the fault signal, and generates a fault report sheet, so that the relevant management personnel can handle the fault in time according to the fault report sheet.
