Abstract
The utility model relates to a mining belt conveyor emergency stop device. The mining belt conveyor emergency stop device consists of a plurality of emergency stop device units arranged along the line of a belt conveyor, wherein each emergency stop device unit consists of a flameproof casing and a circuit body; the circuit body is placed in the flameproof casing; a laser emission sensor and a laser receiving sensor are arranged on two sides of the circuit body respectively; the laser emission sensor of each emergency stop device unit and the laser receiving sensor of the next emergency stop device unit are positioned on the same straight line; and power wires are introduced from trumpet-shaped mouths on two sides of the flameproof casing. The mining belt conveyor scramming device has a simple structure, is convenient to use, solves the problem that the belt conveyor under the mine is difficult to control to stop, and is suitable for being used under coal mines containing explosive gas (methane) and coal dust.
Description
Technical field
The utility model relates to a kind of emergency stop device that is used for mining travelling apron.
Background technology
Common travelling apron shutdown feature is to use the backguy emergency stop switch under the coal mine at present; Promptly at travelling apron every backguy emergency stop switch of at a distance from about 50-100 rice, installing along the line; Get up with steel rope or solid wire joint between the backguy emergency stop switch; In the time of need stopping the belt operation, just firmly spur the backguy emergency stop switch, make travelling apron out of service.Sometimes the total length of travelling apron is near 30 kms, and the backguy emergency stop switch of installing along the line reaches thousands of, because the hook of protrusions such as anchoring net sheet; Usually " mix backguy dead "; Sometimes also can break, cause the backguy emergency stop switch ineffective, can cause various accidents.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of easy to operate, mining flexibly travelling apron emergency stop device of control is provided.
The mining travelling apron emergency stop device of the utility model is installed in by a plurality of arrangements that the single emergency stop device unit of travelling apron on along the line form; Each emergency stop device unit is made up of flameproof enclosure and circuit body; Circuit body places in the flameproof enclosure; Laser emission sensor and laser pick-off sensor are installed on circuit body; Described Laser emission sensor and laser pick-off sensor lay respectively at the both sides of flameproof enclosure, and the Laser emission sensor on each emergency stop device unit and the laser pick-off sensor of next emergency stop device unit are positioned on the same linear position, and power lead is introduced from the both sides loudspeaker mouth of flameproof enclosure.
The mining travelling apron emergency stop device of the utility model has utilized the good characteristics of laser alignment property; Adopt the laser of the following intensity of 1mw to replace backguy; As long as with hand or other object blocks laser once, i.e. may command explosion-proof switch outage stops the travelling apron operation.
The mining travelling apron emergency stop device of the utility model is simple in structure; Not only circuit reaches the intrinsic safety performance; And simplified method of application, and solved that travelling apron is difficult to control a difficult problem out of service under the mine, be applicable under the coal mine that contains damp (methane) and coal dust and use.
Description of drawings
Fig. 1 is the structural representation of the mining travelling apron emergency stop device of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing mining travelling apron emergency stop device is done further to describe.
A kind of mining travelling apron emergency stop device; The emergency stop device unit identical by a plurality of structures constitutes; Each emergency stop device unit is made up of flameproof enclosure 1 and circuit body 2, and circuit body 2 places in the flameproof enclosure 1, and Laser emission sensor 3 and laser pick-off sensor 4 are installed on the circuit body 2; Laser emission sensor 3 and laser pick-off sensor 4 lay respectively at the both sides of flameproof enclosure 1, and power lead is introduced from the both sides loudspeaker mouth 5 of flameproof enclosure 1.
According to the actual environment needs,, guarantee during installation that the laser pick-off sensor 4 of Laser emission sensor 3 and next emergency stop device unit on each emergency stop device unit is positioned on the same linear position with of the arrangement along the line of emergency stop device unit along travelling apron.Circuit body 2 is responsible for emission of lasering beam and is received laser beam with surveying; When the laser beam that sends when arbitrary emergency stop device unit is blocked; Circuit body 2 does not receive laser beam and sends control signal, the outage of instruction explosion-proof switch, and electrical motor is out of service; All emergency stop device unit all do not have electricity simultaneously, quit work.Have only behind trouble-shooting, explosion-proof switch closes a floodgate, the emergency stop device unit again electric, normal operation, thus guaranteed operating personnel's personal safety.
