Description
Technical field:
The utility model relates to the roadway safety device, especially a kind of inclined shaft automatically closing safe door gear.
Background technology:
At present in mine during transported material because so well depth is provided with transport inclined shaft, so that mine truck transported material back and forth in inclined shaft.Owing to be inclined shaft, when mine truck moves on the slope, be easy to glide and cause driving.In order to prevent runaway accident, in inclined shaft, be provided with the monitoring screen, air humidity is big in inclined shaft, usually causes electrical equipment to make moist, the screen lens blur, the operation malfunctioning, though be provided with car arrester, can not fundamentally avoid runaway accident in the inclined shaft exit.
The utility model content:
The purpose of this utility model provides a kind of inclined shaft automatically closing safe door gear, and its flexible operation, sensitivity are good, safe and reliable.
The technical solution of the utility model is: described a kind of inclined shaft automatically closing safe door gear, wherein hoist engine is fixed on the ground on opposite, exit of inclined shaft, be fixed with the elevator pulley frame between the exit of described hoist engine and inclined shaft, at the top of elevator pulley frame the elevator head sheave is housed, the messenger pulley is housed on the support of elevator pulley frame, in elevator pulley frame middle and lower part the messenger pulley is housed also, the knick point part is equipped with the elevator land wheel below the exit of inclined shaft, one end of hoisting rope is connected on the hoist engine, and the other end passes through the elevator head sheave respectively, the elevator land wheel is connected on the mine truck; Safety door is installed in the inclined shaft medium position, the arch top of inclined shaft is equipped with the messenger pulley above safety door, the messenger pulley also is installed above the exit of inclined shaft, one end of safety door messenger is connected steel-wood structure on the safety door through these two messenger pulleys respectively and keeps off a car on the messenger card at plate middle part, the other end is connected on the messenger movable pulley through two other messenger pulley respectively, and the messenger movable pulley is connected on the hoisting rope.
The doorframe of described safety door is fixed on the inclined shaft both sides, and the steel-wood structure plate of keeping off a car is hung on the crossbeam of doorframe by the soft chain of steel.
The utility model is installed simple, and flexible operation, sensitivity are good, safe and reliable, and fault rate is low, thoroughly stops runaway accident, and is practical, and the material materials are few, and infusion of financial resources is few, can be widely used in the roadway transport inclined shaft.
Description of drawings:
Fig. 1 is a fitting arrangement of the present utility model;
Fig. 2 is a safety door structural representation enlarged drawing of the present utility model.
Specific embodiments:
As Fig. 1, shown in 2, safety door 1 of the present utility model is installed in the inclined shaft medium position, the arch top of inclined shaft is equipped with messenger pulley 2 above safety door 1, messenger pulley 3 is installed above the exit of inclined shaft, knick point 13 parts are equipped with elevator land wheel 14 below the exit of inclined shaft, on the ground on the opposite, exit of inclined shaft, be fixed with hoist engine 8, between the exit of inclined shaft and hoist engine 8, be fixed with elevator pulley frame 10, at the top of elevator pulley frame 10 elevator head sheave 6 is housed, messenger pulley 5 is housed on the support of elevator pulley frame 10, in elevator pulley frame 10 middle and lower parts messenger pulley 9 is housed, one end of hoisting rope 11 is connected on the hoist engine 8, and the other end is through difference elevator head sheave 6, elevator land wheel 14 is connected on the mine truck 15; One end of safety door messenger 4 (seeing the dotted line among Fig. 1) is connected steel-wood structure on the safety door 1 through messenger pulley 3 and messenger pulley 2 respectively and keeps off a car on the messenger card 19 at plate 18 middle parts, the other end is connected on the messenger movable pulley 7 through messenger pulley 5, messenger pulley 9 respectively, and messenger movable pulley 7 is connected on the hoisting rope 11.The doorframe 17 of safety door 1 is fixed on the inclined shaft both sides, and the steel-wood structure plate 18 of keeping off a car is hung on the crossbeam 16 of doorframe 17 by four soft chains 20 of steel.Still kept car arrester 12 in knick point 13 the place aheads below the exit of inclined shaft.
When mine truck 15 promotes with normal speed, thereby hoisting rope 11 is subjected to gravity and the exceptionally straight pulling messenger movable pulley 7 that makes progress by drooping the relaxed state that gets off, being connected safety door messenger 4 on the messenger movable pulley 7 is subjected to the pulling force plate 18 of automatically steel-wood structure being kept off a car and raises up, mine truck 15 is passed through smoothly, after mine truck 15 passes through knick point 13, because of gravity disappearance hoisting rope 11 lands naturally, safety door messenger 4 is no longer stressed, and the steel-wood structure plate 18 of keeping off a car automatically falls under self-gravity action and closes.After the slinger links to each other mine truck 15 and hoisting rope 11 hooks, when mine truck 15 down moves, hoisting rope 11 is subjected to mine truck 15 actions of gravity and drives safety door messenger 4 again and promote the steel-wood structures plate 18 of keeping off a car, and makes mine truck 15 pass through safety door smoothly.If the slinger pushes inclined shaft because of thought paralysis breaks off relations with mine truck 15, hoisting rope 11 is not subjected to mine truck 15 actions of gravity, and the steel-wood structure plate 18 of keeping off a car is still closure state, so just can block driving, prevents the accident generation.
