Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] Such as figure 1 Shown: The broken rope protection device of the underground aerial passenger monkey car, including the broken rope arresting device, pressure sensing system and control system.
[0023] The broken rope arresting device consists of a support 2, two levers, a pair of brake shoes 3 and a telescopic support power source 1. The two levers are respectively hinged with the bracket 2 at the middle position, and the two connecting points keep a set distance. The upper and lower brake shoes of a pair of brake shoes are respectively hinged to the two ends of the same side of the two levers, and the two support ends of the telescopic support power source are respectively hinged to the ends of the other side of the two levers.
[0024] The support 2 of the broken rope arresting device is fixed on the crossbeam. An idler roller 4 is respectively arranged o...

The invention provides a rope breaking protecting device of a downhole overhead man-riding monkey transportation device. The rope breaking protecting device comprises a rope breaking catching machine device, an induction system and a control system, wherein the rope breaking catching machine device is designed through adopting a connecting rod structure, and has the characteristics of being low in cost and stable in structure, and can adopt controlling manners of electromagnet control or pneumatic control according to different downhole environments; the induction device consists of a sensor module and a Zigbee terminal node; the sensor module is used for receiving tensioning force information of a steel wire rope, and transmitting the tensioning force information to the Zigbee network by the terminal node; and the control system is used for receiving wireless network information, monitoring the tensioning force of the steel wire rope of the monkey transportation device, and after the rope breaking accident is occurred is judged, sending an alarm to an alarm system, and sending a command to a catching device. According to the rope breaking protecting device disclosed by the invention, a wireless network is adopted, so that communication is more convenient and stable, and the maintenance cost is reduced; the tensioning force of the steel wire rope is real-time detected, so that a rope breaking accident can be prevented in advance, and when the rope breaking accident occurs, the rope breaking protecting device is quickly reacted; and the catching machine device can more quickly and more stably enclasp the steel wire rope, so that occupants are better protected.
Description
technical field [0001] The invention relates to a protection device, in particular to a rope breakage protection device for a monkey car, which is an overhead passenger device in a coal mine, which can effectively prevent the occupants from being injured by the sudden disconnection of the wire rope when the monkey car is running in the coal mine. Background technique [0002] The aerial ropeway device used in underground mines is commonly known as "monkey cart". The drive wheel and wire rope are driven by the output power of the driving device, so as to realize the purpose of transporting miners. During the operation of the monkey car, once a rope breakage accident occurs, the monkey car will slide and fall under the action of force, which may cause casualties to passengers and damage to transportation facilities. At present, the use of monkey car wire ropes in coal mines is not standardized, especially there is no legal basis for the inspection, maintenance and replacement...
