Abstract
The utility model discloses an inclined drift winch interlocking normal closed automatic block device technology, which is used for mine operation. The utility model is composed of a winch interlocking controller, a bracket, a frame-typed arrester, an infrared sensor, a hydraulic raiser and a buffering seat which is arranged in a track. The arrester always lies in a closure state when opened, when a mine car moves upwards or downwards, the winch interlocking controller enables the hydraulic raiser to open or close the arrester. The utility model has the advantages of high degree of automation, safety, simple structure and low cost; the utility model can effectively block the winch which slides downwards at any time to prevent the loss caused by the accident that the winch moves. The utility model is widely suitable for medium and small sized coal mines.
Description
The utility model relates to the technical field of safety devices in mine or the tunnel, and is especially a kind of by the hydraulic pressure normally closed arrester safety device of circuit realization with the interlock of winch interlocking.
In order to ensure the safety in production of colliery inclined shaft, prevent the generation of derailing accident, people have carried out a large amount of research aspect Type Protection Device for Inclined Shaft Runaway Car in recent years, have proposed many new technical schemes.There are electronic, pneumatic and hydrostatic drive etc. in lifting aspect as alley stopping device; Shaped steel door case type, the steel rope energy-absorption type peace post obstacles formula in track etc. that crouches is being arranged aspect the kind of alley stopping device.These anti-buffer stops all can brought into play certain effect aspect the production of guarantee mine safety.Yet the alley stopping device that has is not in normally off, just just start alley stopping device later in that derailing accident has taken place, so that the property examined is poor; The structure that has is too complicated, and particularly with the winch interlocking that can not link, degree of automation is low.
The purpose of this utility model be exactly provide at the deficiencies in the prior art that a kind of suitable middle and small scale coal mine uses, with the automatic arrester technology of normally closed of winch interlocking.
The purpose of this utility model is achieved in that this inclined gallery automatic arrester device of winch interlocking normally closed is arranged on the downside near grade change point, arrester is in normally off, when winch energising starting promptly enters the interlocking linkage status, receive the signal of mine car upstream or downstream when the infrared ray sensor after, winch interlocked control device is by executive circuit control lifter opening and closing arrester.Concrete structure of the present utility model is made up of winch interlocked control device, two infradred sensors, support, hydraulic rockshaft, arrester, buffing pads, support is fixed on the roof in tunnel, the upper end of arrester is fastened on the support by connecting pin, the lower end is located on the interior buffing pad of track, and two infradred sensors are separately positioned on the wall on arrester both sides; Hydraulic rockshaft is made up of Hydraulic Station, transport pipe, oil cylinder, slide shaft, track adjusting wheel, pulley and steel rope, and Hydraulic Station is formed one by electrical motor, fuel tank and oil pump and is fixed on the below of support; Slide shaft is arranged in the chute of support, and the piston rod of oil cylinder and slide shaft welding are fixed and by connecting pin oil cylinder be fixed on the support; Track adjusting wheel is welded on the downside of oil cylinder front end, and pulley is fixed on the support below, and track adjusting wheel is passed at the two ends of steel rope and pulley is connected and fixed with slide shaft, arrester respectively; Buffing pad is made up of connecting panel, spring assembly and the base that becomes with concrete casting, and spring assembly obliquely is fixed on the inclined-plane of base, and connecting panel is arranged on the spring assembly.
Winch interlocked control device is made up of power circuit, infrared ray sensing circuit, testing circuit and executive circuit.
Advantage of the present utility model:
The one, protection effect is good.Because the design of arrester is a normally closed, the framework of arrester is " worker " word steel structure, adds that the top of arrester and support are connected and fixed, and its bottom is provided with buffing pad, so not only protection effect is good, and can not damage other equipment.
The 2nd, the degree of automation height.Owing to adopted and winch interlock control apparatus and infradred sensor, hydraulic rockshaft can prevent the generation of sport car phenomenon effectively according to the situation opening and closing arrester of mine car operation fully.
The 3rd, simple in structure, cheap, installation and maintenance are all very convenient, are adapted at using widely in the middle and small scale coal mine.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model winch interlocked control device work scheme drawing.
As shown in Figure 1, the utility model is arranged on mine inclined downside near grade change point, it is made up of winch interlocked control device, infradred sensor 1 and 16, support 3, hydraulic rockshaft 8, arrester 5, buffing pad 21, and winch interlocked control device includes power circuit, infrared ray sensing circuit, testing circuit and executive circuit; Support 3 is fixed on the roof in tunnel, arrester 5 is the door case type structure, its upper end is fastened on the support 3 by connecting pin 4, and the lower end is located on the buffing pad 21 in the track 17, and infradred sensor 1 and 16 is separately positioned on the wall on arrester 5 both sides; Hydraulic rockshaft 8 is made up of Hydraulic Station 2, transport pipe 6, oil cylinder 11, slide shaft 14, track adjusting wheel 12, pulley 10 and steel rope 9, and Hydraulic Station 2 is formed one by electrical motor 22, fuel tank 23 and oil pump 24 and is fixed on the below of support 3; Slide shaft 14 is arranged in the chute 15 of support 3, and the piston rod 13 of oil cylinder 11 is fixed and by connecting pin 7 oil cylinder 11 is fixed on the support 3 with slide shaft 14 welding; Track adjusting wheel 12 is welded on the downside of oil cylinder 11 front ends, and pulley 10 is fixed on support 3 belows, and track adjusting wheel 12 is passed at the two ends of steel rope 9 and pulley 10 is connected and fixed with slide shaft 14, arrester 5 respectively; Buffing pad 21 is made up of connecting panel 18, spring assembly 19 and the base 20 that becomes with concrete casting, and spring assembly 19 obliquely is fixed on the inclined-plane of base 20, and connecting panel 18 is arranged on the spring assembly 19.
Principle of work of the present utility model and working process are:
Arrester is in normally off, when winch energising starting promptly enters the interlocking linkage status.When mine car was up, first infradred sensor was received signal and is made lifter work by winch interlocked control device, and the high pressure oil of Hydraulic Station oil pump output enters oil cylinder through transport pipe, drives steel rope and open arrester when piston rod is released forward.When mine car continues to be up to second infradred sensor, winch interlocked control device will receive the working power of cutting out Hydraulic Station behind the signal, and oil cylinder loses pressure, thereby make arrester lean on the weight of self to fall and recover closed condition.When mine car is descending, winch interlocked control device second infradred sensor as first sensor and repeat above-mentioned action.When mine car generation derailing accident,,, prevent the loss that derailing accident causes so at any time can both block the sport car of downslide effectively because arrester is in closed condition at ordinary times all the time.
