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 Dian Ti Coupe case.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 Dian Ti Coupe case 1 and CWT2 are located at the two ends that are wound on the steel rope on the winch 5.The two ends difference She Zai Coupe case 1 of belt conveyor 3 and the bottom of CWT2.Urgent counterweight 4 is installed on the belt conveyor 3 balance of Tiao Jie Coupe case 1 and CWT2 under the occasion when promptly rescuing etc.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, taking place to have a power failure etc., Shi Dian Ti Coupe case 1 stops at the occasion in the middle of the floor, in order to rescue the passenger in so urgent moment, rescues the passenger thereby general using drg open system 6 ， Shi Coupe casees 1 move to nearest floor.This drg open system 6 carries out manually openly to the drg of winch 5, led to the overbalance of Coupe case 1 and CWT2, make Coupe case 1 up or down direction move.But; when Coupe case 1 and CWT2 average out (than as the passenger in the Coupe case 1 is a half of qualification number), even opening drg Coupe case 1 this moment also can't move, so on the belt conveyor 3 of She Zai Coupe case 1 bottom, load onto the balance of urgent counterweight 4 Tiao Jie Coupe casees 1 and CWT2, its overbalance Er Shi Coupe case 1 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 Dian Ti Coupe case, the other end is provided with counterweight; Each end is installed in the belt conveyor of Dian Ti Coupe lower box part and counterweight bottom; Thereby be located on the belt conveyor urgent counterweight when urgent with the mobile Dian Ti of the balance Coupe case of Tiao Jie Coupe case and counterweight; Detect urgent counterweight and whether hang over detecting device on the belt conveyor.
Again, according to lift appliance of the present invention, hang on the belt conveyor when its detecting device detects urgent counterweight, then Shi Dian Ti Coupe case is in to move and stops.
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 Dian Ti Coupe case, and when detecting the load of urgent counterweight, then the operation of Shi Dian Ti Coupe case stops.
[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 Dian Ti Coupe lower box part structure 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 mobile the stopping of Dian Ti Coupe case 1 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, produce overbalance between urgent counterweight 4 Shi Coupe casees 1 and the CWT2, 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.
Embodiment 2
Utilize Fig. 2 that another embodiment of lift appliance of the present invention is explained.Fig. 2 is the expanded view of Dian Ti Coupe lower box part structure 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.Pin 8 under the one Duan Yi Coupe case of this beam 9 is that fulcrum is provided with rotationally.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 Dian Ti Coupe case 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 Dian Ti Coupe case, the other end are provided with counterweight, each end is installed in the belt conveyor of Dian Ti Coupe lower box part 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 mobile Dian Ti of the balance Coupe case of Tiao Jie Coupe case 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 running status.
