When an operator ascends, one end of the pull rope 4 is hung on the operator to be ascended, the physical consumption of the operator in ascending can be reduced by means of the downward self-gravity of the balance weight, the other person at the other end of the rope loosens the rope, and the rope loosening speed is consistent with the ascending speed of the operator; when an operator suddenly falls, the anti-falling device 2 is automatically triggered to be locked, the operator is firmly hung, after the operator stands stably again, the anti-falling locking device 2 is triggered to be automatically released, the operator continues to rise, and when the operator rises to the top, the other person can stay the rope to be fastened.
The anti-falling device 2 shown in fig. 2 comprises a third fixed pulley 22, a second fixed pulley 27 and a fourth fixed pulley 24, wherein outer rings of the third fixed pulley 22, the second fixed pulley 27 and the fourth fixed pulley 24 are sequentially connected through a pull rope 4, a wheel shaft of the second fixed pulley 27 is connected to the bottom of a connecting rod 21 and is fixedly connected with the top of the coal bunker 1 through the connecting rod 21, wheel shafts of the third fixed pulley 22, the second fixed pulley 27 and the fourth fixed pulley 24 are connected through a fixing plate 23, the third fixed pulley 22 is connected to the middle of the connecting rod 21 through a spring 26, the coal bunker 1 is provided with a ladder stand 7 at one side close to the anti-falling device, and a fixing part 8 for fixing the pull rope 4 is arranged at the other side opposite to the ladder stand 7; the connecting rod 21 is rotatably connected with the fixed plate 23, and the connecting part between the fixed plate 23 and the second fixed pulley 27 is connected with the connecting rod 21 through a connecting shaft.
When an operator descends, one end of the pull rope 4 is hung on the descending operator, the other person stands on the counterweight side and stays the rope to be pulled up, the speed of the pull rope 4 is consistent with the descending speed of the operator, and the descending weightlessness of the operator can be reduced by virtue of the downward self-gravity of the counterweight; when the operator descends and suddenly falls, the anti-falling device 2 is automatically triggered to be locked, the operator is firmly suspended, the anti-falling locking device 2 is triggered to automatically release after the operator stands stably again, the operator continues to descend, and the operator is stretched, taken down and fixed when the operator descends to the bottom.
The counterweight device 5 is a load-bearing ball, the top of the ball is provided with a pull ring matched with tension, and the pull rope 4 passes through the pull ring to be connected with the anti-falling device and the first fixed pulley.
After the person triggers the fall protection blocking device 2 and the person stands steadily, the spring 26 pulls the fall protection device 2 to unblock under the action of elasticity.
Example two
Fig. 3 is the utility model relates to a stress analysis diagram for coal bunker, according to the atress condition shown in the figure, prevent weighing down the spring safety calculation that blocking device chooseed for use:
From hooke's law: calculating formula of coefficient of stiffness of the spring:
(spring specification: d 2mm, G7900, Nc 95-2 93, Dm 10-2 8mm)
The elastic force of the spring is F ═ kx ═ 0.33X 105 ═ 34.6N
(original spring length 175mm, initial state 230mm, total length after elongation 280mm)
The weight-bearing sphere m is 8KG, the safe flame-retardant rope phi is 16mm, the breaking force is 400KG, and when a person climbs upwards, the person can fall down by means of the balance weight, so that the labor intensity of the person climbing upwards is reduced.
The pulley block in the transmission system is a fixed pulley (the direction of force can be changed only, and the magnitude of the force can not be changed) and is represented by a moment balance formula: (F1-F4) × L1 ═ F × L2
F4-COS 45 × F bullet-0.7 × 34.6-24.2N
F1＝[(F×L2)/L1]+F4＝81.2N
Therefore, when the force of the human body acting on one end of the pull rope with the hook is larger than 81.2N, the anti-locking device is automatically triggered.
after the anti-falling locking device in the coal bunker is triggered, only when a person stably stands on the ladder again, the downward external force applied to the F1 side disappears, and the locking device is triggered to be released under the action of the force of the balance weight and the force of the spring to restore the original state.
Adopt this technical scheme, through adopting the spheroidal mode of assembly pulley cooperation heavy burden, make operating personnel have certain safety guarantee at the in-process that rises and descend, the in-process that rises, the operating personnel of the heavy burden ball cooperation other end carries out the pull-up operation to it, can reduce the physical power and the time that operating personnel rose and used, and owing to go down and go upward two kinds of operation modes through the eminence operation personnel, but the emergency whereabouts in-process automatic triggering anti-falling device shutting of operating personnel, get up firm the hanging of personnel, thereby prevent the emergence of operation personnel from eminence falling accident, the safety of eminence operation personnel has been guaranteed, construction work efficiency is improved, construction safety has been guaranteed, the safety effect is showing, and work efficiency is improved.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
