Abstract
The utility model relates to the improvement of a supporting can and an anti-collision beam devices in a lifting system of the primary mine, an infrared control system (7) and a tension spring (9) are additionally arranged, and a supporting claw (1) can rapidly reach the right position in time; cushion pads (4'), (4) are additionally arranged on an anti-collision beam (10) and a supporting beam (5), the impact force of a lifted container after the overwinding is reduced, and the serious accident that the lifted container falls in a well is effectively prevented from occurring. The utility model has the characteristics of simple structure, safety, convenient installation, good anti-collision and fall prevention effects, little investment, etc., enhances the safety performance of a lifting system and is a better safety device.
Description
The utility model is the safety guard in a kind of mine hoisting system, is when in a single day lifting container takes place to promote pulleying, protects automatically, avoids taking place the infrared ray automatic guidance holder jar and the collision prevention girders device of great falling accident.
Though the most elevator system of present domestic mine have multiple electric prospection; and there is not collision prevention girders; more there is not Tank-supporting device; elevator system can not avoid taking place the lifting container overwind trouble fully when promoting, in case overwind trouble takes place; sheave wheel platform to elevator system produces havoc; and causing lifting container or counterweight to weigh down the great personal injury of well, the serious accident of device damage has seriously influenced the safety in production of mine.For this reason, there is the minority mine that collision prevention girders and Tank-supporting device have been installed, but do not have shock absorber, when pulleying takes place, fully by the distortion energy-absorbing of claw, joist and collision prevention girders of holder jar, therefore claw can not be in time again sometimes, and the generation of lifting container or counterweight falling accident is arranged still the time, existing also have the only a few mine on Tank-supporting device by the dress buffer buffers, the complex structure of energy disperser and buffering slideway, steel consumption is big, is not easy to by dress, and investment is big.
The purpose of this utility model just provides a kind of infrared ray automatically controlled holder jar and collision prevention girders device with better buffer capacity.The lifting container pulleying can be in case when taking place in it, prevent that effectively lifting container or counterweight from weighing down the generation of well grave accident, guarantees mine safety production, and simple in structure, by convenient, safe and reliable, the small investment of dress.
The utility model utilizes the claw in the infrared ray control Tank-supporting device to break off relations, in case the pulleying phenomenon takes place, claw is broken off relations to put in place, and on collision prevention girders and joist, have additional cushion rubber, slowed down the impulsive contact force of lifting container to collision prevention girders and claw, joist, prevented the generation of falling accident effectively, and original device has been carried out necessary improvement.
Introduce the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model scheme drawing;
Fig. 2 is the utility model Tank-supporting device scheme drawing.
The utility model is improved on the basis of former holder jar and collision prevention girders device, Tank-supporting device of the present utility model is made up of claw (1), axle bed (2), extension spring (9), joist (5), cushion rubber (4), unhook cross bar (6), infrared ray control system (7) etc., one end of claw (1) connects by the reinforcement (3) on the derrick of axle bed (2) and elevator system, and the other end hangs on the unhook cross bar (6).Between claw (1) and joist (5), extension spring (9) is housed.One end of glue hook cross bar (6) is that a hook hangs with claw (1), and the other end is controlled can block by rotating projection (8) in the system (7) by infrared ray, cushion rubber (4 ') is housed, the available polyurethane of cushion rubber (4 ') at the upside of joist (5).
Collision prevention girders of the present utility model (10) is that the downside in former collision prevention girders has additional cushion rubber (4), the available timber of cushion rubber (4).
Infrared ray control system of the present utility model (7) is made up of photoelectric relay, infrared probe, projection (8) etc., and unhook cross bar (6) blocks by projection (8) in infrared ray control system (7).Photoelectric relay (7) signal that emits beam feeds back to photoelectric relay by infrared probe, and photoelectric relay control projection (8) carries out revolution work.
When mine hoisting container generation pulleying continues to rise, infrared probe is by shading, photoelectric relay (7) action, the projection (8) of photoelectric relay (7) is thrown off unhook cross bar (6), unhook cross bar (6) is thrown off claw (1), after claw (1) is thrown off unhook cross bar (6), under the effect of deadweight and extension spring (9), drop on the cushion rubber (4) of joist (2) down rapidly, put in place in advance rapidly.Lifting container continues to rise and hits to collision prevention girders (10), has set up cushion rubber (4 ') because of collision prevention girders of the present utility model (10), has alleviated the impact of lifting container to collision prevention girders (10), has also alleviated the reaction force of collision prevention girders (10) to lifting container simultaneously.Drop on the claw (1) that has put in place in advance after the lifting container bump collision prevention girders (10), owing to set up cushion rubber (4) on the joist (5), slowed down the impulsive force of lifting container again greatly to claw (1), joist (5), just prevented that also claw (1) is out of shape because of impact is excessive, can not hold lifting container, cause the generation of weighing down the well grave accident.
The utility model has been set up extension spring (9) again owing to adopted the infrared ray automatic control technology between claw (1) and joist (5), claw (1) is put in place rapidly in advance; On joist (5) and collision prevention girders (10), set up cushion rubber (4), (4 '), slowed down the impact of lifting container, prevented the serious falling accident that lifting container causes because of pulleying effectively claw (1), joist (5) and collision prevention girders (10).Therefore, the utlity model has infrared ray automatic guidance pioneering technology, simple in structure, safe and reliable, convenient by dress, crashproof, anti-fall effective, characteristics such as small investment have improved the safety performance of mine hoisting system, are a kind of safety devices preferably of local mine.
Claims (1)
1. one kind by holder jar and collision prevention girders (10) infrared ray automatic guidance holder jar and the collision prevention girders device formed, it is characterized in that the utility model also set up infrared ray control system (7), between claw (1) and joist (5), extension spring (9) is housed, upside at joist (5) is equipped with cushion rubber (4), at the downside of collision prevention girders (10) cushion rubber (4 ') is housed; Unhook cross bar (6) blocks by projection (8) in infrared ray control system (7).
