Abstract
The utility model relates to a speed-limiting safety hook for a vertical shaft cage, which comprises a cage, a guide rope, a guide wheel group, an eccentric wheel group and a connecting rod automatic operating mechanism. The utility model has the advantages of automatic operation and starting, flexible and safe operation, good effect on speed limiting and anti-dropping, easiness and convenience for resetting, simple structure, firmness, endurance, low cost and easy installation and maintenance.
Description
The utility model relates to a kind of vertical shaft hoisting safety device, particularly a kind of vertical cage speed limit falling protector.
At present, in the lifting of coal mine shaft lining cage, for avoiding lifting winch malfunctioning, cut off the power supply in the lifting process, hoist ropes break and the cage that causes hypervelocity descends, major accidents such as the weightlessness or the jar of squatting, people have taked many countrmeasures: the falling protector that adopts standardized Wedge type slider type as in big-and-middle-sized colliery, but complex structure, cost is big, little colliery is difficult for installing and promoting, some falling protectors that go out at small-sized vertical Coal Mine Design, structure is undesirable, anti-fall effect is all not so good, and is not too practical, and many small-sized vertical colliery is arranged in addition, usually be not take anti-fall safety measure, accident takes place to give country, society causes very big loss.
The utility model provide at above-mentioned the deficiencies in the prior art part a kind of automatic operation starting, flexible operation safety, speed limit anti-fall effective, simple in structure, durable, cost is low, the vertical cage speed limit falling protector of easy popularization.
The purpose of this utility model is achieved in that vertical cage speed limit falling protector, comprise cage, guide rope, the guiding wheels, eccentric group, also comprise the connecting rod automatic manipulation mechanism, the connecting rod automatic manipulation mechanism is by a pair of boxed rod, a pair of lower link, the pair of rotary shafts that links to each other with eccentric group, suspension bracket that links to each other with main hoisting cable and retracing spring are formed, boxed rod links to each other with suspension bracket by bearing pin, boxed rod links to each other by bearing pin with lower link, lower link and S. A. are fixedly linked, retracing spring be located at suspension bracket and and the fixed mount that is fixedly linked of cage between, S. A. is by the axle sleeve location that is located on the fixed mount.
In the utility model, eccentric wheel can be changed to cam, and its driving surface is the spill arc surface, matches with guide rope.Guide rope is located between the guiding wheels and between the eccentric group.With the cage line of centers is the boundary, and connecting rod automatic manipulation mechanism, guiding wheels and eccentric group are the symmetry structure, can be provided with protecting sheathing in the three outside.This falling protector can with the supporting use of vertical cage energy disperser.
The utility model has the advantages that: operable automatically starting, flexible operation safety, speed limit are anti-fall effective, reset easily convenient, simple in structure, durable, cost is low, easy installation and maintenance, be suitable for promoting etc.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the fit structure scheme drawing of guide rope and guiding wheels and eccentric group.
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, Fig. 2, shown in Figure 3, vertical cage speed limit falling protector, comprise cage (15), guide rope (1), guiding wheels (2), eccentric group (4) and connecting rod automatic manipulation mechanism, the connecting rod automatic manipulation mechanism is by a pair of boxed rod (7), a pair of lower link (8), the pair of rotary shafts (5) that links to each other with eccentric group (4), suspension bracket (12) that links to each other with main hoisting cable (10) suspension hook (11) and a pair of retracing spring (6) are formed, a pair of boxed rod (7) links to each other with suspension bracket (12) by a pair of bearing pin (13), a pair of boxed rod (7) links to each other by a pair of bearing pin (16) with a pair of lower link (8), a pair of lower link (8) is fixedly linked with pair of rotary shafts (5), a pair of retracing spring (6) be located at suspension bracket (12) and and the fixed mount (14) that is fixedly linked of cage (15) between, four S. A.s (5) are located by a pair of axle sleeve (9) that is located on fixed mount (14) and cage (15) sidewall separately respectively, eccentric wheel (4) is fixedly linked with S. A. (5), respectively establish one group of guiding wheels (2) in the upper and lower end parts of cage (15) lateral wall, guide rope (1) is by the line of centers of guiding wheels (2) or eccentric group (4).Suspension bracket (12) top links to each other with lifting main rope (10) by suspension hook (11).With cage (15) line of centers (17) is the boundary, and connecting rod automatic manipulation mechanism, guiding wheels (2), eccentric group (4), guide rope (1), retracing spring (6), S. A. (5) are the symmetry structure.
In the utility model, when cage (15) normal running, retracing spring (6) is in tensioning and draws high state, and eccentric group (4) also is in open configuration, guide rope (1) can freely pass through between guiding wheels (2) and eccentric group (4), and falling protector is in off working state.When causing decline of cage (15) hypervelocity or weightlessness when main rope (10) fracture or because of lifting winch is malfunctioning, retracing spring (6) is retracted for clearance automatically, connecting rod mechanism shrinks, driven rotary axle (5) rotation, eccentric group (4) rotation is closed tight, and eccentric wheel (4) touches and produce friction force upwards mutually with guide rope (1), drives eccentric group (4) and tightly presss from both sides position guide rope (1), thereby reach the purpose that cage (15) slows down or stops, thereby avoid accident to take place.
Claims (5)
1, vertical cage speed limit falling protector, comprise cage (15), guide rope (1), guiding wheels (2), eccentric group (4), it is characterized in that: it also comprises the connecting rod automatic manipulation mechanism, the connecting rod automatic manipulation mechanism is by a pair of boxed rod (7), a pair of lower link (8), the pair of rotary shafts (5) that links to each other with eccentric group (4), suspension bracket (12) that links to each other with main hoisting cable (10) and retracing spring (6) are formed, boxed rod (7) links to each other with suspension bracket (12) by bearing pin (13), boxed rod (7) links to each other by bearing pin (16) with lower link (8), lower link (8) is fixedly linked with S. A. (5), retracing spring (6) be located at suspension bracket (12) and and the fixed mount (14) that is fixedly linked of cage (15) between, S. A.
