Abstract
Invention provides a kind of cage bumper in mine auxiliary shaft winch system, it utilizes the friction buffer principle, mainly form by buffering body, the slide block of living, belleville spring, pressing plate, buffering slideway, baffle plate, bolt, have simple in structure, small investment, safe and reliable is applicable to advantages such as large, medium and small type mine.
Description
The invention belongs to the mine hoisting safety guard.
No matter mine hoist equipment is full-automatic or semi-automatic control system at present, all can not eliminate the lifting pulleying fully and cause De Dun jar accident, threatening personal life security, be the anti-Dun jar accident of giving birth to of sending out of ending, coal in China portion regulation, Fu Jing shaft bottom level need have 6 meters distance of overfall downwards, with Yan Huan Dun jar, but can not be according to solving the pulleying problem, general Fu Jing shaft bottom has only downwards about 2 meters, and pit shaft is extended on production limit, limit, not only influence is produced, and needs 200,000 yuan of investments.
According to the data at home and abroad of grasping at present; still incomparable more satisfied De Fang Dun jar Machine guarding; the domestic employing rubber washer that has is made elastic buffer, and the container of pulleying hits at a high speed in the above, the compression rubber; general 2 meters high cushion rubber amount of compression is about 0.8 meter; its buffer distance is short, and deceleration/decel a value is big, and is not definite value; behind the rubber pressurized, also have resilience, and can only on 1 ton of cage equipment, use.
The Machine guarding that the purpose of this invention is to provide a kind of actv. Fang Zhi Dun jar.
Invention is achieved in that this pulleying prevent Dun jar shock absorber, utilizes the friction buffer principle, and shock absorber is by buffering body, the slide block of living, belleville spring, pressing plate, survey piece, gland, bolt and cushion slideway and form.
Be described in detail the present invention below in conjunction with accompanying drawing:
Fig. 1 is the front elevation of shock absorber.
Fig. 2 is the cutaway view of shock absorber along the A-A line.
Fig. 3 is the cutaway view of shock absorber along the B-B line.
Fig. 4 is the shock absorber scheme of installation.
Wherein 1-cushions body, 2-slide block alive, 3-belleville spring, the 4-pressing plate, 5-surveys piece, 6-gland, the 7-bolt, 8-cushions slideway, the lockhole on the 11-buffering slideway, 12-slide block boss alive, 13-mining i beam, the original H-girder of 14-, the 15-chassis, the horizontal bridle of 16-, the 17-collar, 18-pit shaft I-beam section, the 19-cage.
Found out by Fig. 2: 6 bolts (7) are tightened gland (6) are moved inwards, by surveying piece (5), pressing plate (4), belleville spring (3), the slide block (2) of living, the buffering slideway (8) that is clipped in the buffering body (1) being produced positive pressure, the opposite side (left side) of buffering body (1), then buffering slideway (8) is produced antagonistic force (positive pressure), because tightening of bolt (7) will be cushioned slideway (8) and clamp.In order to increase friction force, the slide block (2) of living adopts plastic asbestos material, and a slide block boss alive (12) is arranged on it, has prevented belleville spring (3) displacement.
Clamp the size of positive pressure, extrapolate according to the needs of different cage friction buffer power.This power shows its size by surveying the outer resistance dynamometer that connects of piece (5).
The installation of shock absorber as shown in Figure 4, two buffering bodies (1) are installed in the shaft bottom level respectively apart from 200 millimeters places, cage (19) outside, be fixed on the upper end and the original H-girder of pitshaft (14) as the mining i beam (13) that supports, mining i beam (13) lower end withstands on the shaft bottom, for increasing fastness, be welded with chassis (15) as mining i beam (13) bottom of supporting usefulness, seat props up in the shaft bottom, in order to increase stability, mining i beam (13) also welds with the original H-girder in shaft bottom (14).Two buffering slideways (8) are clipped in respectively in the two buffering bodies (1), its lower end is exposed 150 millimeters, and with horizontal bridle (16) with the lock be connected with lockhole (11), above 2 meters of shaft bottom level is vertically stretched in buffering slideway (8) upper end, and limit it with the collar (17) and swing, the collar (17) is contained on the pit shaft I-beam section (18).
After cage (19) high speed pulleying, produce very big impulsive force above stopping a jar position, pound on horizontal bridle (16), because horizontal bridle (16) is connected with the pin-and-hole (11) of buffering slideway (8), buffering body (1) is fixed on the mining i beam (13), horizontal bridle (16) is subjected to momentum effect to draw buffering slideway (8) to move down in the lump, because buffering body (1) is clamped on the buffering slideway (8) all the time, produce positive pressure, when buffering slideway (8) has then produced reverse equivalent friction buffer power when moving down, cage (19) has obtained even deceleration/decel a thus, about 1.5 meters of buffer distances, can effectively cage (19) be stopped, after cage (19) stops, winding cage (19) unclamps bolt (7) then, will cushion slideway (8) and horizontal bridle (16) again and move to the initial position and tighten and get final product.
The present invention utilizes the equation of dynamics formula according to the concrete parameter of mine, calculates the positive pressure of shock absorber to buffering slideway (8) exactly, friction buffer power, and deceleration/decel a and buffering distance are generally selected cage (19) overreach buffer deceleration/decel a=5-10 meter per second
2, about buffer distance L=1.5 rice.
This shock absorber takes place under the serious pulleying situation at mine, guaranteed the safety of the person and equipment, only needed 0.5 hour, do not influenced production from taking place to be rolled onto to resume production, have simple in structure, small investment, safe and reliable, be applicable to advantages such as large, medium and small type mine.
