Abstract
The utility model relates to the technical field of safety protection on coal mine underground working surface, in particular to a drawing wire protection device. When in working, the person or article falls into a reversed loader carelessly, as the scraping plate link chain of the reversed loader has high speed, the person death or device damage can be caused if rescue is untimely. The drawing wire protection device is arranged on a middle part groove at the tail part of the reversed loader, and one ends of a plurality of nylon soft ropes are fixed on a right baffle, and the other ends thereof are connected with a hoisting cable by a locking screw, and the middle part groove crossing the tail part of the reversed loader is in a tightening state; the hoisting cable surrounds two pulleys, one end of the hoisting cable is connected to a switch at the left end of an emergency locking switch, and the other end thereof is tightly buckled at the right end of the emergency locking switch by a turn-buckle, and a closed ring is formed by the hoisting cable and the emergency locking switch by the turn-buckle. The nylon soft ropes are drawn for controlling the emergency locking switch, leading the reversed loader and a crusher electric motor to be stopped and preventing accidents.
Description
Technical field
The utility model relates to the security protection technology field of working surface production under the coal mine, specifically a kind of stay guard.
Background technology
Colliery mining face under mine conveyer and stage loader unloading segment are because produce in the time of need having the staff in working order usually in this regional work.Because carelessness of staff, violate safe operation rules or equipment in component (crossing over the helper position) fatigue damage meet accident, drop accidentally in elevating conveyor when personnel or article are crossed over the elevating conveyor unloading segment when in working order, because elevating conveyor scraper chain speed is very high, and very short apart from the crusher in crushing cavity length; If do not rescue immediately then must cause personnel death, property loss, device damage.This situation happens occasionally in the work plane accident, and the production in colliery is caused the economic loss that is difficult to predict and produces obstacle.
Summary of the invention
The purpose of this utility model provides a kind of stay guard, is able to safety, produces smoothly to guarantee coal mine work area production.
The technical solution of the utility model is: stay guard is made up of right baffle-plate, right baffle plate, lock-screw, nylon tightrope, support line seat, axle bed, pulley, urgent latch switch, screw-button, wire rope; Left baffle by Bolt Connection on the intermediate channel of elevating conveyor tail, every nylon tightrope is fixed on two lock-screws, a lock-screw is fixed on the right baffle plate, through hole is arranged at the bottom of another lock-screw, the steel wire penetrating through hole connects with the nylon tightrope, and several nylon tightropes become tensioned state across elevating conveyor tail intermediate channel; 2 groups of axle beds are installed in respectively that go up in the right baffle-plate outside, the left and right sides of first and last root nylon tightrope, and pulley is installed on the axle bed; The steel wire penetrating right baffle-plate, around two pulleys, the one end is connected on the switch of urgent latch switch left end, with the right-hand member of wire rope fastening at urgent latch switch, wire rope forms a closed-loop with urgent latch switch by screw-button to the other end by screw-button; Urgent latch switch is fixed on the right baffle-plate outside, and the electrical control part of urgent latch switch links with crushing engine, elevating conveyor motor respectively; Support line seat is fixed on the right baffle-plate inboard between two axle beds, and is fluted on it, is used for supporting steel-cable.
The beneficial effects of the utility model are: solved the safety problem that falls into people and thing in the elevating conveyor unloading segment because of meeting accident when the work of stage loader, crushing engine, guarantee as possible fall into people's life security and fall into the use value of thing, be the technical guarantee of Safety of Coal Mine Production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of the stay guard structural representation that the utility model proposes.
Fig. 2 is the vertical view of the stay guard structural representation that the utility model proposes.
The specific embodiment
Among the figure: 1. right baffle-plate, 2. right baffle plate, 3. lock-screw, 4. nylon tightrope, 5. support line seat, 6. axle bed, 7. pulley, 8. urgent latch switch, 9. screw-button, 10. wire rope.
From Fig. 1,2 as can be known, stay guard by right baffle-plate 1 and right baffle plate 2 by Bolt Connection on the intermediate channel of elevating conveyor tail, every nylon tightrope 4 is fixed on two lock-screws 3, a lock-screw 3 is fixed on the right baffle plate 2, through hole is arranged at the bottom of another lock-screw 3, wire rope 10 passes through hole and connects with nylon tightrope 4, and several nylon tightropes 4 become tensioned state across elevating conveyor tail intermediate channel; 2 groups of axle beds 6 are installed in respectively on right baffle-plate 1 outside, the left and right sides of first and last root nylon tightrope, and pulley 7 is installed on the axle bed 6; Wire rope 10 passes right baffle-plate 1, centers on two pulleys 7, the one end is connected on the switch of urgent latch switch 8 left ends, with the right-hand member of wire rope 10 fastenings at urgent latch switch 8, wire rope 10 forms a closed-loop with urgent latch switch 8 by screw-button 9 to the other end by screw-button 9; Urgent locking 8 switches are fixed on right baffle-plate 1 outside; It is inboard fluted on it that support line seat 5 is fixed on right baffle-plate 1 between two axle beds 6, is used for supporting steel-cable.
When people or object fall into elevating conveyor, the person of falling into or other staff spur nylon tightrope 4 (4 nylon tightropes, be distributed on the joint intermediate channel), the through hole of nylon tightrope 4 below lock-screw 3 passes and is connected on the wire rope 10, wire rope 10 moves by the pulley 7 that is fixed on the axle bed 6, realization quits work crushing engine, elevating conveyor motor and guarantees the safety of the person and property the control of urgent latch switch 8.The electrical control part of urgent latch switch links with crushing engine, elevating conveyor motor respectively.Urgent latch switch 8 and the ring of wire rope 10 by a sealing of screw-button 9 formation; no matter the operator spurs A-B among Fig. 2; C-D; E-F still is that nylon tightrope of G-H; can make urgent latch switch 8 work; when people or thing fall in the elevating conveyor accidentally; the staff on the person of falling into or next door spurs the nylon tightrope in the stay guard immediately; realize the work of urgent latch switch by the reciprocating motion of nylon tightrope; afterwards make crushing engine; the stage loader motor quits work and realizes protecting the safety that falls into elevating conveyor unloading segment people and thing, realizes the purpose of safeguard protection.
Present embodiment is on a joint intermediate channel stay guard to be installed, and can on a joint or more piece intermediate channel above-mentioned stay guard be installed according to actual needs in the production.
