Description
[technical field]
The present invention relates to a kind of lift appliance, the present invention especially provides the restored method of the safety of a kind of machine room-less elevator from urgent state restoration to usual state.
[background technology]
As an example of lift appliance, there is the Japanese Patent spy to open that 2000-351548 communique and Te Kai 2000-169055 communique put down in writing, as shown in Figure 3.Fig. 3 is the section drawing of traditional lift appliance structure.
In Fig. 3,1 is lift car.2 is counterweight (CWT).3 is belt conveyor.4 is urgent counterweight.5 is winch, is located at the elevating road top.6 is the drg open system.
Above-mentioned lift car 1 and CWT2 are located at the two ends that are wound on the steel rope on the winch 5.The two ends of belt conveyor 3 are located at the bottom of car 1 and CWT2 respectively.Urgent counterweight 4 is installed on the belt conveyor 3 under the occasion when promptly rescuing etc., regulates the balance of car 1 and CWT2.Make the drg of winch 5 open by the drg open system 6 that is located on the winch 5 in addition.The drg open system 6 of this winch 5 locates to carry out remote manipulation by occupant side of the superiors etc.
Action when urgent describes to traditional elevator device shown in Figure 3 below.
Such as, take place to have a power failure etc., make lift car 1 stop at the middle occasion of floor, in order to rescue the passenger in so urgent moment, general using drg open system 6 is rescued the passenger thereby make car 1 move to nearest floor.This drg open system 6, the drg of winch 5 is carried out manually open, by the overbalance of car 1 and CWT2, make car 1 up or down direction move.But, when car 1 and CWT2 average out (such as the half of the passenger in the car 1) for the qualification number, even open drg this moment, car 1 also can't move, so on the belt conveyor 3 that is located at car 1 bottom, load onto urgent counterweight 4, regulate the balance of car 1 and CWT2, make its overbalance and car 1 is moved.
Above traditional elevator device restores after rescuing the passenger to usual operation, once occurs forgetting taking off urgent counterweight, and urgent counterweight falls down and damages the problem of machine.
The present invention carries out in order to address the above problem, and its purpose is: a kind of lift appliance is provided, and described lift appliance can take off urgent counterweight to forgetting, the situation that causes can't restoring to usual operation is controlled.
[summary of the invention]
In order to achieve the above object, lift appliance of the present invention comprises: the winch that is located at the lifting well headroom; The steel rope that be wound on the hauling block of winch, the one end is provided with lift car, the other end is provided with counterweight; Each end is installed in the belt conveyor of lift car bottom and counterweight bottom; Thereby be located on the belt conveyor urgent counterweight when urgent with the balance moving elevator car of regulating car and counterweight; Detect urgent counterweight and whether hang over detecting device on the belt conveyor.
Again,, hang on the belt conveyor, then make lift car be in operation and stop when its detecting device detects urgent counterweight according to lift appliance of the present invention.
Have, according to lift appliance of the present invention, its detecting device is a photoswitch again, when urgent counterweight covers the illuminating part of photoswitch and the light beam between the light accepting part, then is judged as urgent counterweight and hangs on the belt conveyor.
Again, according to lift appliance of the present invention, its detecting device is located at the bottom or the counterweight bottom of lift car, when detecting the load of urgent counterweight, the operation of lift car is stopped.
[accompanying drawing simple declaration]
Fig. 1 is the section drawing of structure of the lift appliance of the 1st example of the present invention.
Fig. 2 is the expanded view of lift car bottom section of the lift appliance of the 2nd example of the present invention.
Fig. 3 is the section drawing of traditional elevator apparatus structure.
[preferred forms of invention]
Below utilize accompanying drawing that example of the present invention is explained.
Embodiment 1
Utilize Fig. 1 that the 1st example of lift appliance of the present invention is described.Fig. 1 is the section drawing of structure of the lift appliance of the 1st example of the present invention.
Among Fig. 1,7 is the photoswitch of detecting device, is located at the bottom surface of elevating road, and whether illuminating part and the light beam between the light accepting part that green phase is right are blocked, and whether thing are arranged by detecting.If the state that urgent counterweight 4 is contained in belt conveyor 3 restores down to usual operation, the urgent counterweight 4 that then is contained on the belt conveyor 3 is blocked the light beam of photoswitch 7, forgets and take off that the mobile of lift car 1 stops, and can't restore to usual operation thereby detect urgent counterweight.
But, in Fig. 1, have identical or cooresponding part with conventional example shown in Figure 3 and put on identical symbol, therefore omit its explanation, only to describing with Fig. 3 difference.
Like this, be provided with photoswitch 7 in the bottom surface of elevating road, whether be blocked by illuminating part and the light beam between the light accepting part photoswitch 7, whether urgent counterweight 4 is to be contained in state on the belt conveyor 3, whether lift appliance can restore to usual operation is detected, so can not occur in urgent counterweight 4 forgets under the state that takes off, directly restore to the situation of usual operation, prevent that urgent counterweight from falling down the generation of the accident of damage machine.
Again, can prevent such unfavorable condition: forgotten to take off urgent counterweight 4, and lift appliance is restored to usual running state, at this moment, urgent counterweight 4 makes between car 1 and the CWT2 and produces overbalance, thus, cause again such as when the full operation of passenger, the friction force between rope and the winch pulley is not enough and produce and slide etc.
Utilize Fig. 2 that another embodiment of lift appliance of the present invention is explained.Fig. 2 is the expanded view of lift car bottom section of the lift appliance of the 2nd example of the present invention.
Among Fig. 2, the 9th, beam, an end of belt conveyor 3 is hung thereon.One end of this beam 9 is that fulcrum is provided with rotationally with the pin under the car 8.The 10th, spring acts on the weight of the belt conveyor 3 of beam 9 at the other end side bearing of beam 9.The 11st, switch as the throw rod of beam 9, is left behind downwards and then is controlled at the usual operation of lift appliance.When belt conveyor 3 and the dress weight of urgent counterweight 4 thereon make spring 10 compressions, then this throw rod is left behind downwards.
Like this, throw rod is left behind downwards, and switch 11 closes, and then can be judged as urgent counterweight 4 and be contained on the belt conveyor 3, stops in the recovery of forgetting under the state that takes off urgent counterweight 4 to the usual operation of elevator.
Above-described is in the bottom of lift car 1 integrative-structure to be set, but this structure also can be located at the bottom of CWT2.
As mentioned above, lift appliance of the present invention comprises: the winch that is located at the lifting well headroom, be wound on the hauling block of winch, the one end is provided with the steel rope that lift car, the other end are provided with counterweight, each end is installed in the belt conveyor of lift car bottom and counterweight bottom, thereby be located on the belt conveyor urgent counterweight when urgent, detect urgent counterweight and whether hang over detecting device on the belt conveyor with the balance moving elevator car of regulating car and counterweight.Lift appliance of the present invention can prevent elevator when usual running state is restored, because of forgetting the situation that urgent counterweight falls down urgent counterweight to damage machine etc. of taking off.
[effect of invention]
As mentioned above, lift appliance of the present invention is machine room-less elevator especially, can provide a kind of from the state of emergency Safe restored method to usual operation state.
