Among Fig. 5, in the open mechanism 40 of the 2nd braking, spur downwards, just can make open bar 41 actions of the 2nd braking, and brake equipment 20 is opened by the 2nd rope portion of braking a side of open bar 41 that is fixed with the 2nd operation rope 43.As mentioned above, by spurring the 2nd operation rope 43, and with the connecting part pulled down of open bar 41 of the 2nd braking and the 2nd operation rope 43.The 2nd pulley 42 rotates towards the direction of arrow of Fig. 5 thereupon.Thus, the open bar 41 of the 2nd braking is that fulcrum is rotated with the leading section with the open bar 41 of the 2nd braking of fulcrum platform 29 butts of the basket 27 of electromagnet, and the 2nd open bar engagement section 44 pushes stopper head 28a towards the below.For action after this, the occasion of braking the action of opening mechanism's 30 braking releasings with common brake equipment 20 and the 1st is identical, the power of plunger 28 is passed to brake control lever 23 from brake rod 26, and the elastic force that overcomes retarding spring 24 makes the braking of brake equipment 20 obtain removing.In addition, when the open bar 41 of the 2nd braking moves,, cut off, the open bar 41 of the 2nd braking can be moved and will fix the 2nd static line 17 of braking open bar 41 and counterweight 10 by spurring the 2nd operation rope 43.
Below, to the open mechanism 30 of the 1st braking of moving and the open mechanism 40 of the 2nd braking by the above in fact under what kind of occasion difference use and describe.
Than the occasion that lift car 4 weighs, select the open mechanism 30 of the 1st braking in the counterweight 10 that is equipped with brake equipment 20, utilize the braking of 31 pairs of brake equipments 20 of the open bar of the 1st braking to remove.On the contrary,, select the open mechanism 40 of the 2nd braking, utilize the braking of 41 pairs of brake equipments 20 of the open bar of the 2nd braking to remove in counterweight 10 occasion lighter than lift car 4.
Usually, counterweight 10 that causes according to the variation of the patronage of lift car 4 up and down and the weight overbalance between the lift car 4, and can produce counterweight 10 occasion lighter than lift car 4 than the heavy occasion of lift car 4 and opposite counterweight 10.Therefore, when the braking of brake equipment 20 was removed, according to the state of the number of taking, counterweight 10 existing situations about being moved upward had situation about moving again downwards.
As mentioned above, use the open bar 31 of the 1st braking, the occasion heavier than lift car 4 that be counterweight 10 promptly is the occasion that brake equipment 20 open back counterweights 10 are moved towards the below.Here, in case make open bar 31 actions of the 1st braking, the masterpiece that overcomes 31 couples of stopper head 28a of bar pressing force that then makes progress is used for the fulcrum platform 29 that the fulcrum to bar 31 supports.Therefore, in counterweight 10 occasion lighter than lift car 4, promptly, brake equipment 20 is opened the occasion that back counterweights 10 move towards the top, in case use the open bar 31 of the 1st braking, then counterweight 10 moves towards the top identical with the power that acts on fulcrum platform 29, so because of the thrust pressure of 31 couples of stopper head 28a of the open bar of the 1st braking disappears, the situation that the operation that the braking of generation brake equipment 20 is removed can't normally be carried out.
In addition, as mentioned above, use the open bar 41 of the 2nd braking, the occasion lighter than lift car 4 that be counterweight 10 promptly is the occasion that brake equipment 20 open back counterweights 10 are moved towards the top.Opposite with this occasion, when brake equipment 20 is opened, the occasion that counterweight 10 moves towards the below is used the open bar 41 of the 2nd braking, then bar 41 is a fulcrum with the leading section with the bar 41 of fulcrum platform 29 butts, the stopper head 28a that desire will engage with the pars intermedia of bar 41 pushes towards the below, but counterweight 10 declines this moment, the thrust pressure of 41 couples of stopper head 28a of bar disappears, the situation that the operation that the braking of generation brake equipment 20 is removed can't normally be carried out.
Therefore, as mentioned above,, select to use in the open mechanism of the 1st and the 2nd braking according to the state of patronage in the lift car 4.
Open employed the 1st pulleys 32 of mechanism of brake equipment 20 braking and the 2nd pulley 42 of the winch 10 of present embodiment 1 are made of iron, but but also lighter synthetic resin make.In addition,, also can make by lighter syntheticfibres for the 1st operation rope 33 and the 2nd operation rope 43, iron to replace.In case the moment of inertia of pulley and operation rope is bigger, then usually when the elevator acceleration and deceleration, the power that is applied to the open bar effects of counterweight 10 synchronization-moving brakings from operation rope also increases, and becomes sometimes braking the interference of open mechanism.Therefore, make the operation rope of plastic pulley and synthetic resin fiber system,, can reduce the possibility of the open mechanism of braking misoperation than iron lightweight.
Above embodiment 1 has following effect.
Because the brake equipment 20 that carries on counterweight 10 with winch 11 has the open mechanism of braking that is made of the open bar of braking, operation rope and a pair of pulley, even the occasion that can't carry out electrical control to the opening of brake equipment 20 when event is urgent, also can be from the mechanically braking of brake off device 20 on the ground, service personnel there is no need to go to and is equipped with the place that winch 11 counterweights 10 are stopped brake equipment 20 is opened, can be easily, reliably lift car 4 is moved to nearest floor and rescue the passenger.
In addition, because the open mechanism of braking is made of the 1st and the 2nd liang of open mechanism of group braking, so in the occasion of counterweight 10 than lift car 4 weights, or in two kinds of situations of the occasion lighter than lift car 4, can select to use the open mechanism of the braking that is fit to each occasion, be not subjected to unbalanced influence of counterweight 10 and lift car 4 weight, can stably remove the braking of brake equipment 20.
In addition, the open bar 41 of open bar the 31, the 2nd braking of the 1st braking all is used as fulcrum platform 29 with the part of electromagnet basket 27, make its effect of playing fulcrum, but fulcrum platform 29 is nearer from the stopper head 28a that becomes point of action, and is best as fulcrum on the position.And electromagnet basket 27 and counterweight 10 frameworks 14 itself are all very firm, so intensity is fine, are suitable as fulcrum.
In addition, lift car 4 is when common lifting, and open bar 31 of the 1st braking and the open bar 41 of the 2nd braking utilize static line 17 respectively and be fixed on each counterweight 10, thereby can suppress the influence of the interference that the moment of inertia of pulley and operation rope causes.
