The non-attended aerial cable car system of the invention can effectively control unsafe behaviors of human, eliminate the unsafe states of matters, and ensure the safety of passengers on the aerial cable car, thus having good protection effect.
Description
Technical field
The present invention relates to a kind of people's of taking advantage of cable car, relate in particular to a kind of non-attended aerial cable car system.
Background technology
Require according to " safety regulations in coal mine ": when the upper and lower main gradient tunnel vertical depth of personnel surpasses 50 meters, should take machinery to transport personnel.In order to alleviate the physical demands of the upper and lower class of employee on road, the built on stilts people's cable car of taking advantage of has been installed in many collieries on upper and lower mountain, this system is made up of the soft initiator of PLC power supply box, operator's station, drive motor, drg etc., and native system can be divided into three kinds of continuous operation mode, unmanned pattern and maintenance patterns.Operating to of unmanned pattern wherein: take advantage of people's cable car head, tail to get off offside switch (also claiming limit switch) a little is set respectively built on stilts, when passenger is got off when a little in time not getting off, use the bar of beating that health (with left arm or right arm) touches limit switch, the normally closed contact of limit switch is opened, system's automatic train stop.As starting once more, press reset button.After the system reset, just can restart.The pedestrian gives the PLC control box by the photoelectric switch induced signal of upper and lower website, need not by any button, the built on stilts people's cable car of taking advantage of will be by above-mentioned mode automatic starting operation, 3 minutes automatic train stops of time-delay after last people gets off, all protections are worked under this kind pattern, but have a following drawback: personnel rectify at the built on stilts sitting posture of taking advantage of on people's cable car, make bar as offside then can touching, the normally closed contact of limit switch can be opened, and makes somebody a mere figurehead and takes advantage of people's cable car then can stop; But employee's energy is not concentrated or health crooked (or lean person's build person) sometimes, touches less than making bar after offside; the normally closed contact of limit switch is not opened; do not have protective effect, the personnel that then can cause are got rid of or are collided other obstacle by the centripetal force of cable car tail wheel, make the injury to personnel evil.That therefore, uses at present takes advantage of people's cable car system protection effect bad.
Summary of the invention
The purpose of this invention is to provide a kind of effective non-attended aerial cable car system of protecting.
For achieving the above object, the technical solution used in the present invention is:
A kind of non-attended aerial cable car system, comprise and take advantage of people's cable car, take advantage of people's cable car to draw by haulage cable, haulage cable is erected on the holder rope sheave, the holder rope sheave is lifted by suspension rod, suspension rod can be fixed on the wall, the holder rope sheave is relative rotary connection with suspension rod, it is characterized in that: between two adjacent suspension rods, be provided with offside suspension rod, offside suspension rod can be fixed on the wall, the relative rotary connection in offside suspension rod lower end has offside holder rope sheave, be positioned at offside holder rope sheave top during the haulage cable normal operation, on the offside holder rope sheave weighting block be installed, be connected with magnet on the weighting block, on the offside suspension rod speed sensor is installed, the orthogonal projection of magnet can overlap with speed sensor when offside holder rope sheave rotates.
After using personnel of the present invention offside, under the effect of gravity, haulage cable can descend and touch offside holder rope sheave, offside holder rope sheave is rotated, rotate, make magnetic patch trigger the speed sensor action thereby drive magnet, the speed sensor contact by often open transfer to normally closed, to head PLC control box, the PLC action takes advantage of people's cable car to stop automatically to signal by head, tail sensor.Actv. of the present invention has been controlled people's unsafe acts, has eliminated the unsafe condition of thing, has guaranteed that personnel take the built on stilts safety of taking advantage of people's cable car, protect effective.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of non-attended aerial cable car system, comprise and take advantage of people's cable car, take advantage of people's cable car by haulage cable 6 tractions, as shown in Figure 1, haulage cable 6 is erected on the holder rope sheave 1, holder rope sheave 1 is by suspension rod 2 liftings, suspension rod 2 can be fixed on the wall, holder rope sheave 1 is relative rotary connection with suspension rod 2, between two adjacent suspension rods 2, be provided with offside suspension rod 3, offside suspension rod 3 can be fixed on the wall, and the relative rotary connection in offside suspension rod 3 lower ends has offside holder rope sheave 5, is positioned at offside holder rope sheave 5 tops during haulage cable 6 normal operation, on the offside holder rope sheave 5 weighting block 7 is installed, be connected with magnet 8 on the weighting block 7, on the offside suspension rod 3 speed sensor 4 be installed, the orthogonal projection of magnet 8 can overlap with speed sensor 4 when offside holder rope sheave 5 rotates.
Take advantage of the present invention, after personnel are offside, under the effect of gravity, haulage cable can descend (record by in-place test, the weight of 60kg is at distance holder rope sheave 1m place, haulage cable decline 68mm).During actual fabrication, at distance holder rope sheave 1m place, an offside holder rope sheave is installed, the horizontal center line of offside holder rope sheave is than the low 60mm of horizontal center line of forward and backward holder rope sheave.Under normal operation, offside holder rope sheave does not contact with haulage cable, remains static, and promptly offside holder rope sheave does not change; After personnel are offside, because people's action of gravity haulage cable descends, touch offside holder rope sheave, offside holder rope sheave rotates.Speed sensor is fixed on the offside suspension rod, the gap of the offside holder rope sheave of speed sensor distance is 10mm～50mm, be fixed with magnet on the offside holder rope sheave, driving magnet when offside holder rope sheave rotates rotates, magnet triggers the speed sensor action, and the speed sensor contact transfers normally closed (24v) to by often opening, signal by head, tail sensor to head PLC control box, the PLC action makes the cable car automatic train stop.
The present invention has installed the offside holder rope sheave that has the speed protection effect in offside section, this section index steel rope offside holder rope sheave that do not rub when normal operation, and offside holder rope sheave does not change; Offside as the employee, the index steel rope descends, and the offside holder rope sheave that rubs is rotated, and speed protection works, and control loop disconnects.
The present invention only needs a speed sensor, small magnet, a little iron plate (being weighting block) when making, utilize existing holder rope sheave, only needs investment units up to a hundred, can finish.
The present invention has protective effect to all offside personnel (no matter no matter fat or thin sitting posture how), as long as personnel are offside, just can stop immediately.
