Wire rope online real-time monitoring and alarm system (software copyright registration number: 2015SR071787)
When the wear of the steel wire rope reaches 3%, the system will issue an alarm and a voice prompt saying "Steel wire rope wear reaches 3%, please prepare to replace it"; When the steel wire rope is worn to 6%, the control system will issue an alarm and a voice prompt saying "Steel wire rope is worn to 6%, please prepare to replace it"; When the steel wire rope is worn to 10%, the control system will issue an alarm and a voice prompt saying "Steel wire rope is worn to 10%, please prepare to replace it"; And the overhead passenger device stops running, it can only start running after replacing the new steel wire rope.
Turning and rope retraction device for fixed gripper (patent number: ZL201920413073.1)
The device mainly has three functions. Firstly, it can achieve fixed rope gripper turning, capable of turning at an angle of ≥ 90 ° in the same direction or in an "S" shape, and can also turn on horizontal tunnels or slopes. The second is the "monkey car" that can achieve unilateral or bilateral rope retraction and is suitable for running fixed grippers in narrow tunnels or belt tunnels. The third is to provide technical support for remote monitoring, unmanned functions, and future development of IoT control platforms, providing the best technical support for the automated operation of mechanized personnel replacement and intelligent personnel reduction in mining.
Aerial passenger device IoT supervision system (patent number: ZL201720388316.1)
This system is a remote monitoring platform for the Internet of Things, which is a scientific research project designated by the State Administration of Coal Industry to be developed by our company. It realizes remote monitoring of the Internet of Things in ten "monkey cars" at Pingmei Second Mine. It is currently an IoT remote monitoring system that our company has successfully designed and operated for nearly a hundred monkey cars from multiple users.
This system is a cloud service IoT monitoring system that integrates the production, operation, management, and multi-sensor information fusion control of aerial passenger devices for monitoring and fault diagnosis analysis. To ensure the safe operation of overhead passenger devices, we provide monitoring, early warning and forecasting, predictive maintenance and management, and information platform sharing for manufacturing enterprises and coal mine users. Greatly improving the dynamic management efficiency of overhead passenger devices, truly achieving the integration of industrialization and informatization.
Wireless emergency stop device for aerial passenger device (patent number: 201320509226.5)
The traditional emergency stop method for overhead passenger devices along the line is a wire emergency stop, but this method is prone to emergency stop failure or misoperation due to the influence of the slope of the tunnel, the weight of the emergency stop wire rope itself, and the distance between the wire ropes; On the other hand, when the "monkey car" is in the same lane as other auxiliary transportation equipment, the installation bracket for emergency stop by pulling wires can easily cause traffic obstacles. The successful application of the monkey car wireless emergency stop control device can effectively solve this problem. In case of emergency, passengers only need to touch the emergency stop signal transmitter button on the suspension chair at any position to achieve emergency stop.
Online detection and alarm of braking force of wheel brake Patent number: (201510794576.4)
The online detection device for the braking force of the wheel brake detects the braking force of the wheel brake in real time, and displays the magnitude of the braking force of the wheel brake in real time through the electronic control device. When the detected braking force is less than the set value, the electronic control device will sound a fault alarm "wheel brake force exceeding limit protection", and at the same time control the overhead passenger device to stop, realizing the detection and protection of the braking performance of the wheel brake, ensuring the safety of personnel.
Wear detection of wheel lining (patent number: 201521111011.3)
The wheel lining wear detection device adopts high-frequency data communication technology and radio frequency wireless communication technology to detect the degree of wear of the wheel lining of the driving wheel and supporting rope wheel device of the coal mine overhead passenger device in real time, preventing excessive wear of the wheel lining and causing dangerous accidents such as wire rope slipping and falling, thereby reducing the safety operation risk of passengers and equipment. When the electronic control device detects that the wheel liner has reached its limit of wear, a voice alarm will sound "Drive wheel liner wear has reached its limit, please replace the wheel liner in a timely manner" to control the overhead passenger device to protect the parking.
Wire Rope Broken Rope Catcher (Patent Number: ZL201320704185.5)
The wire rope catcher is installed on the traction wire rope when
1. When the power output shaft and drive wheel malfunction;
2. When the friction between the steel wire rope and the driving wheel is insufficient;
3. When the drive wheel shaft is broken or the drive wheel falls off;
4. When the steel wire rope breaks.
The catcher can directly catch and brake the traction steel wire rope, avoiding accidents and ensuring the safety of equipment and personnel. It is suitable for all grippers.
Flying car seat blocking device (patent number: ZL201721080402.2)
Using the principle of backstop, when the "monkey car" experiences flying or slipping, the suspension chair is forcibly blocked to block and stop one to two people within every two spans of the crossbeam, in order to avoid accidents of multiple deaths and injuries caused by collisions between passengers during flying or slipping. It can effectively protect the personal safety of passengers when the current three-level braking device (high-speed braking, safety braking, and wire rope braking) loses its braking force.
(Patent number: ZL201010579953. X ZL201010579976.0)
When the suspension chair is running on a slope, if there is slippage between the gripper and the steel wire rope, it may cause the suspension chair to slide freely down the slope, which may cause safety accidents. To prevent similar accidents, a flying car blocking device as shown in the figure can be installed. When the monkey car is running normally, the seat blocking device is in the open state. In case of a flying accident, the seat blocking device can be closed by electronic control or manual means to prevent the suspension chair from sliding down.
Wire rope braking device (patent number: ZL201220418988. X)
Using the principle of wedge slider clamping, powered by an explosion-proof thruster, the steel wire rope entering and exiting the driving wheel is braked, and the braking efficiency is 100%. When the "monkey car" is running, the possible situations that may occur are:
1. The low-speed safety brake loses braking force, and the system loses braking force;
2. The friction between the steel wire rope and the driving wheel is insufficient, causing the system to produce a flying car;
3. Drive wheel axle breakage, drive wheel falling or steel wire rope falling off track causing speeding.
After the above situations occur, serious accidents such as speeding and slipping may occur. The wire rope brake can effectively prevent accidents by braking the wire rope. It is suitable for friction type detachable hanging slings and caliper type detachable hanging slings.
