[0002] During the transportation of the single rail hoist in the coal mine shaft, there are potential safety hazards caused by reasons such as vehicle slipping and material dropping, which endanger the safe production of the mine. Conducting safety warnings in the operation interval of the single rail hoist and implementing closed management in the operation interval can effectively eliminate potential safety hazards and improve the safety of system operation. Summary of the Invention

[0003] One advantage of the utility model is to provide a single rail hoist for coal mine safety transportation. By using the mine UWB positioning system, the position of the hoist is accurately positioned, and a personnel proximity protection device is designed and manufactured. When the distance between personnel (non-permitted approaching personnel) and the equipment reaches 15 m, an alarm is triggered, and when the distance reaches 7 m, the hoist stops running. This effectively prevents non-staff from accidentally entering the operation area of the single rail hoist. The setting of the safe distance between people and vehicles realizes the safety warning of the hoist equipment and prevents non-modified personnel from approaching.

[0024] The first embodiment of the present utility model is as follows:

[0025] A single-track hoist for coal mine safety transportation, comprising a suspension rail assembly, a hoist assembly, an anti-collision assembly and a safety assembly. The hoist assembly is movably arranged on the suspension rail assembly. The anti-collision assembly is installed at the front and rear of the hoist assembly. When the hoist runs into an obstacle, the anti-collision assembly acts and the hoist stops in time, effectively eliminating potential driving hazards such as collisions.

[0026] The safety assembly includes a master controller arranged along the transportation line, a communication cable, and several alarms and sensors. The several alarms and sensors are electrically connected to the master controller through the communication cable. The safety assembly also includes a directional antenna, a pyroelectric infrared sensor, an infrared sensor, a camera, a radio frequency sensor and a lidar installed on the hoist assembly. There is an on-vehicle console inside the hoist, which is electrically connected to the anti-collision controller, the safety assembly and the master controller to accurately locate the hoist. Design and manufacture a personnel proximity protection device to achieve an alarm when a non-staff member is within a range of 15 m from the equipment, and the hoist stops running when within a range of 7 m, effectively preventing non-staff members from straying into the operation area of the single-track hoist.

[0027] The anti-collision assembly includes an anti-collision cylinder. A hanging arm is arranged at the upper end of the anti-collision cylinder. The hanging arm is connected to the hanging bracket through a pin shaft. Two sets of traveling wheels are arranged on the hanging bracket and are connected to the suspension rail through the traveling wheels.

[0028] The anti-collision cylinder is a cylindrical structure with one end open. The closed end of the anti-collision cylinder is connected to the hoist to ensure its movement along with the hoist. An anti-collision rod is movably arranged inside the anti-collision cylinder. An anti-collision plate is arranged at one end of the anti-collision rod extending out of the anti-collision cylinder to increase the collision area.

[0029] A connecting plate is arranged at the lower part of the anti-collision cylinder. An anti-collision controller is installed on the side of the connecting plate. A spring column is arranged at the upper end of the anti-collision controller. The spring column can bend laterally. A trigger switch is arranged at the upper end of the spring column. When the trigger switch is triggered, the spring column will bend, and at the same time, the switch circuit inside the anti-collision controller is activated. At this time, the anti-collision controller emits a signal.

[0030] A slot is arranged on one side of the anti-collision cylinder facing the trigger switch. A lever perpendicular to the anti-collision rod is arranged at the end of the anti-collision rod. One end of the lever passes through the slot. In the initial state, the trigger switch and the lever are in a perpendicular state and interfere with each other. When the anti-collision rod moves, the lever moves synchronously and contacts the trigger switch, causing it to rotate in the direction of the movement of the anti-collision rod. At this time, the trigger switch is triggered, the spring column will bend, and at the same time, the switch circuit inside the anti-collision controller is activated. At this time, the anti-collision controller emits a signal to make the hoist stop in time, effectively eliminating potential driving hazards such as collisions.

[0031] The suspended rail assembly includes a suspended rail and several hanging chain groups. The suspended rail is connected to the top of the roadway through several hanging chain groups. Each hanging chain group includes two hooks and two hanging chains connected to the hooks, which can effectively balance the weights of the suspended rail and the crane. The hooks are fixedly connected to the roadway and connected to the suspended rail through the hanging chains to realize the layout of the suspended rail.

[0032] The crane assembly includes a crane and a hanging bracket arranged on the top of the crane. There are two traveling wheels arranged inside the hanging bracket, and the traveling wheels are arranged on the suspended rail in a rollable manner. The crane can move back and forth along the suspended rail.

[0033] The underground single-rail hoisting transportation system is refined into each operation route, and the interval of each route is defined. Infrared induction devices and audible and visual alarms are respectively arranged at the starting ends of each driving route. When the crane enters the starting point of the operation interval, the operation warning system is triggered, and audible and visual warnings are given at each fork and main location within the operation route interval to remind personnel to avoid in time and prevent personnel from straying into. When the crane completes the transportation task and reaches the delivery end point, the end sensor is triggered to end the warning of the operation route.

[0034] For the coexisting area of multiple routes, trigger sensors are overall arranged on the main line and each branch route to prevent unnecessary safety warnings in the unaffected areas and achieve accurate positioning of the warning areas. When the crane runs on the main line, the forks along the way should be warned in time to prevent personnel from straying into; when running from the main line to a certain fork, the unaffected area of the main line is lifted from the warning, and the affected area of the fork continues to be safely warned.
