DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1-3 As shown, a safety guarantee system for inclined tunnel transportation includes a winch driver's operating console 1, a hoisting winch 2, a slide rail 3, a mine car 4, a mine car limiting device 5, a wire rope 6, a wire rope online monitoring system 7, a compressed air pipeline online monitoring and protection system 8, an overhead passenger device 9, a light-sensitive linkage safety door system 10, a regional radar online monitoring system 11, a damper anti-collision device 12, an automatic radar sensing damper 13, an inductive winch overwinding protection device 14, a face recognition unlocking system 15, an air-controlled radar anti-runaway system 16 and a hook online monitoring visualization operation platform system 17. The winch driver's operating console 1 is electrically connected to the face recognition unlocking system 15, the slide rail 3 is arranged in the inclined tunnel, a mine car 4 is arranged on the slide rail 3, the mine car 4 is connected to the hoisting winch 2 by a wire rope 6, and the mine car limiting device 5 is arranged on the slide rail 3.
[0019] Specifically, the mine car limiting device 5 includes a control box 501, a limiting inductive sensor 502 and a car blocker 503. The control box 501 is installed on the inner wall of the inclined tunnel, and the limiting inductive sensors 502 are installed on the front and rear sides of the slide rail 3 and at the positions corresponding to the mine car 4.
[0020] During specific implementation, the limit inductive sensor 502 is electrically connected to the control box 501 , and a plurality of car blockers 503 are provided on the slide rail 3 , and the car blockers 503 are connected to the control box 501 .
[0021] When the mine car 4 is preparing to be lifted and lowered, when the mine car 4 passes through the set limit inductive sensor 502 and the car blocker 503 area, if the number of mine cars 4 exceeds the specified number range, the limit inductive sensor 502 receives the over-trailer signal and transmits it to the control box 501, and the control box 501 will send a command to the car blocker 503 to close and lock the car blocker 503, thereby preventing the train from passing.
[0022] The utility model also provides another mine car limiting device, which utilizes a pneumatic linkage device and two groups of car blockers. First, the first group of car blockers is installed at a reasonable position close to the downslope of the inclined tunnel, and then the reasonable installation position of the second car blocker is determined according to the actual lifting capacity of the on-site inclined tunnel winch (the specified number of hanging mine cars). During the process of lifting and lowering the mine car, by setting the mine car limiting area of the two groups of car blockers, when one group of car blockers is opened, the other group of car blockers will automatically form a closed state through the action of the pneumatic linkage device. If there is an overload of trailers, the excess vehicles will exceed the set range and will be closed outside by the linkage car blocker and cannot pass.
[0023] The wire rope 6 is provided with a wire rope online monitoring system 7, which consists of a wire rope monitor, a control system, and a voice alarm. The wire rope monitor is installed in a reasonable and optimal position so as to perform real-time monitoring during the operation of the wire rope. During the monitoring process, if the wire rope is detected to be worn, deformed, broken, rusted, etc., the monitored information will be automatically transmitted to the control system. The voice alarm of the control system will issue a voice prompt "The wire rope online monitoring is unqualified, please stop the winch". At the same time, the control system will issue a command to the winch to cut off the power, brake, and lock to prohibit operation.
[0024] The compressed air pipeline online monitoring and protection system 8 is set on the compressed air pipeline leading to the inclined lane. The compressed air pipeline online monitoring and protection system 8 consists of an air duct online monitoring pressure sensor, a voice alarm, and a control system. When it is detected that the compressed air pressure in the pipeline is insufficient or there is no compressed air, the information will be transmitted to the control system in a timely and effective manner, and the voice alarm will issue a warning prompt of "the system has no compressed air and the winch stops running". At this time, the control system will issue a command to the hoisting winch to stop running, cut off the power, brake and lock.
[0025] An overhead passenger device 9 is installed above the inside of the inclined tunnel, and a light-sensitive linkage safety door system 10 is set on the right side of the mine car 4. The light-sensitive linkage safety door system 10 is composed of an electronic fence 101, an alarm 102, a gear lever 103 and a cylinder 104. The alarm 102 is a voice alarm. When the winch is running and preparing to lower the mine car, the light-sensitive linkage safety door system also prompts "Pedestrians are prohibited from driving now" at the same time as the voice alarm. The grating (electronic fence) on the light-sensitive linkage safety door system will automatically open to prevent people from entering the dangerous area where the mine car is about to drive, and the "gear lever" on the light-sensitive linkage safety door system will be automatically closed to prompt and prevent people from entering the dangerous area where the mine car is being lifted and lowered, so as to avoid accidents. When the mine car is lifted and lowered, when it reaches the position of the specified distance designed in advance by the control system, the air control device will open the solenoid valve, and the "gear lever" on the light-sensing linked control safety door system will automatically open through the cylinder, allowing the mine car to pass safely. At this time, the (electronic fence) will continue to remain open to prevent people from taking the opportunity to enter the dangerous area and cause a safety accident.
[0026] On the contrary, when the winch is running to lift the mine car on the platform of the unloading yard, the light-sensitive joint-controlled safety gate system (electronic fence) of the unloading yard will automatically open to prevent people from entering the dangerous area for driving. At the same time, the "gear lever" on the light-sensitive joint-controlled safety gate system will remain open to allow the mine car to pass safely. When the winch lifts the mine car and drives past the position set by the light-sensitive joint-controlled safety gate control system, the air control device will open the solenoid valve, and the "gear lever" on the light-sensitive joint-controlled safety gate system will automatically close through the cylinder to remind people not to enter the dangerous area for driving. When the mine car is in the process of lifting and is about to drive to the position set by the light-sensitive joint-controlled safety gate control system of the loading yard, the air control device will open the solenoid valve, and the "gear lever" on the light-sensitive joint-controlled safety gate will automatically open through the cylinder, allowing the mine car to pass safely and enter the loading yard platform. The working principle is repeated over and over again, thereby ensuring the safety of lifting and transportation work.
[0027] A regional radar online monitoring system 11 is installed on the inner wall of the inclined tunnel, and a damper anti-collision device 12 is also installed on the slide rail 3 inside the inclined tunnel. The damper anti-collision device 12 consists of a pressure-free damper, a control system, a gas control device, a proximity sensor, a car blocker, a radar sensor, and a safety light. When the traveling mine car is preparing to pass through the damper, the radar sensor senses that the mine car is about to pass, and the damper will automatically open. When the "proximity sensor" receives that the damper is in a fully open state, it will send a signal to the control system. After receiving the signal, the control system will send an instruction to the gas control device to notify the gas control device to open the solenoid valve through the cylinder to open the car blocker, so that the mine car can pass. When the mine car passes through the damper and crosses the range of the "safety light" and the "radar sensor sensing", the damper will automatically close. At this time, the "proximity sensor" senses that the damper is about to close, and the signal will be sent to the control system again. The control system will immediately send an instruction to the gas control device to open the gas-controlled solenoid valve and close the car blocker through the cylinder, thereby protecting the damper from the risk of being hit.
[0028] The automatic radar sensing damper 13 is composed of a pressure-free damper, a gas control device, a control system, a radar sensor, and a safety light. When the radar sensor on the "automatic radar sensing damper" senses a mine car or a person during the process of the winch lifting and lowering the mine car, the information will be automatically transmitted to the control system. At this time, the control system sends a command to the gas control device to let the control box open the electromagnetic valve, and the pressure-free damper through the cylinder will automatically open, allowing the mine car in motion to pass safely. At the same time, under the action of the "safety light" on the pressure-free damper, the damper will always remain in an open state during the mine car's passage. At this time, under the action of the gas control device interlock, the other damper is in a closed state and cannot be opened, thereby ensuring that the underground ventilation system is normal during the mine car's passage. When the mine car completely drives out of the position sensed by the "safety light" and the "radar sensor" on the automatic radar sensing damper, the signal will automatically be transmitted to the control system again. At this time, after the control system receives the information, it will send a command to the gas control device, and the gas control device will open the electromagnetic valve, and the automatic closing function will be realized through the cylinder pressure-free damper.
[0029] An automatic radar sensing damper 13 is arranged on the right side of the damper anti-collision device 12, and an inductive winch overwinding protection device 14 is arranged on the slide rail 3. The inductive winch overwinding protection device 14 is composed of an inductive sensor, a voice alarm, and a control system. When the mine car drives to the designated position of the inductive sensor installed in the upper and lower parking lots during the inclined tunnel hoisting and transportation work, the inductive sensor uploads the sensed signal to the control system, and the voice box of the control system will issue a voice prompt "The mine car has arrived, please stop the winch". At this time, the control system sends a command to the hoisting winch to stop running, cut off the power, and brake and lock, thereby protecting the winch from overwinding.
[0030] The face recognition unlocking system 15 is composed of a control system, a face recognition video monitoring system, and a voice alarm. The face recognition video will automatically monitor and capture the recognition. If it is recognized that the person is a special type of worker who has been trained and registered as a winch driver, the monitored and recognized information will be automatically transmitted to the control system. Under the control of the control system, the winch power switch will automatically unlock and maintain normal working state.
[0031] On the contrary, if the winch driver is identified as a special position personnel at the post, and there is no special type of personnel who have been trained, the face recognition system will promptly transmit the information to the control system, and the voice alarm will issue a voice prompt "The winch cannot be started because it is not the owner". At the same time, the control system will issue a command to the winch to cut off the power, brake and lock the winch to prohibit operation.
[0032] A plurality of gas-controlled radar anti-runaway systems 16 are arranged on the slide rails 3 of the transport inclined tunnel, and the gas-controlled radar anti-runaway system 16 is composed of an online radar monitoring system, a control system, a gas control device, an anti-runaway device, and a voice alarm. When the winch is running to prepare to lift and lower the mine car, the regional radar personnel online monitoring system will play its role. When the winch is running, if it is detected that there is personnel movement in the unsafe area where the vehicle is driving, the radar online monitoring system will transmit the information to the control system, and the control system will issue a command, and the voice alarm will prompt the "winch stops running due to personnel in the area" warning, and the winch will be powered off and braked and locked to stop running. When the waiting personnel are completely evacuated and the regional radar online monitoring system recognizes that there are no personnel, the information will be transmitted to the control system again, and the feed switch of the control system will be automatically unlocked, and the winch can be operated.
[0033] First, in the inclined tunnel transportation, multiple sets of air-controlled anti-runaway devices are installed at reasonable locations on the track area where the mine car is traveling, and they are kept in a normally closed state during the operation of the winch to prevent runaway accidents. When the winch is operating to lift and lower the mine car, when it passes the distance position set by the control system, the control system will send a command to the air-controlled device to open the solenoid valve, and the anti-runaway devices will automatically open one by one through the action of the cylinder, so that the mine car can pass safely.
[0034] On the contrary, when the winch is running from the inclined tunnel to the parking lot platform and lifting the mine car upward, the mine car being lifted passes each set of anti-runaway devices and reaches the distance position set by the controller system. The control system will send a command to the air control device to let the air control device open the solenoid valve. The anti-runaway devices will automatically maintain a normally closed state through the action of the cylinder to prevent the mine car from running away accidents such as broken ropes and unhooking during driving.
[0035] When the overhead passenger device is opened to transport people, the control system's interlocking function is utilized to allow all of the air-controlled anti-runaway devices and vehicle-blocking doors and other safety facilities along the entire line to automatically open and lock, thereby opening a safe passage for the people riding in the overhead passenger device.
[0036] When the winch is lifting and lowering the mine car, the radar online monitoring system detects abnormal conditions such as broken ropes, unhooked cars, and speeding cars, and the information will be automatically transmitted to the control system. At this time, the control system will issue a command to the voice alarm, and the voice alarm will issue a voice prompt function "The mine car is speeding, please pay attention and avoid it." At the same time, the car-throwing device, car door blocking, anti-runaway facilities, etc., are automatically and forcibly locked through the control system to prevent runaway accidents.
[0037] The visual operation platform 17 for online monitoring of the hook is composed of a control system, a visual operation console, a voice alarm, a radar online monitoring system, a video tracking system for post personnel, and a precise personnel positioning system.
[0038] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the working principle, and the electrical connection between the electrical components should be completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The utility model mainly introduces the working principle and process, and no longer explains the electrical control.
[0039] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that the scope of the present invention is defined by the appended claims and their equivalents.
