Now, explain the operation of elevator rope braking system of the present invention with reference to Fig. 4 a and 4b.
Shown in Fig. 4 a, when elevator 1 was out of service under elevator rope 3 unsupported states, hydraulic actuating cylinder 25 was operated by the operation of hydraulic pressure generation unit 41, thereby the plunger 25a that allows the front end that is arranged on hydraulic actuating cylinder 25 promotes operating panel 35, shown in Fig. 4 b.
Therefore, operating panel 35 slides together in company with Connection Element 27, leave stay bearing plate 23 and overcome spring 29 elastic force and with adapter plate 33 closed contacts, spring 29 is between adapter plate 33 and operating panel 35.
The a plurality of ropes 3 that are arranged between operating panel 35 and the adapter plate 33 can be remained on lock-out state by backing plate 33a and 35a.Just, rope 3 is firmly supported by the lock slots 33b and the 35b that are formed on backing plate 33a and the 35a respectively, and remains on halted state.
When in above-mentioned state by push-botton operation pull on/during following elevator 1, introduce the working fluid jar again according to the working fluid that the signal of elevator 1 is supplied with hydraulic actuating cylinders 25 with hydraulic pressure generation unit 41.Then, be used to promote the plunger 25a indentation hydraulic actuating cylinder 25 of operating panel 35, operating panel 35 overcomes the elastic force of the spring 29 that keeps compressive state between operating panel 35 and adapter plate 33 and leaves adapter plate 33 simultaneously, thereby allow that the elevator rope 3 that remains on lock-out state by backing plate 33a and 35a discharges from lock-out state, shown in Fig. 4 a.Overcome the elastic force of spring 29 and move because the release position of elevator rope 3 can remain to hydraulic actuating cylinder 25 operations and operating panel 35 always, therefore can elevator 1 be pulled on and leave behind with rope towards adapter plate 33.Reference numeral 13 expressions among Fig. 4 a and the 4b are used for fixing and install the device of the shell 11 of elevator rope braking system (A).
When elevator 1 when the adapter plate 33 of lock cell 31 and operating panel 35 are operated according to normal mode under each other with the state of spaced apart, elevator 1 slides during the loading or unloading passenger, perhaps because the degeneration of friction force or the weight difference between elevator cage and the balance block and descend fast or rise between the degeneration of elevator rope braking system braking force and hauling rope and the derrick block, the control unit of elevator sends signals to hydraulic pressure generation unit 41.As mentioned above, come the plunger 25a of compression hydraulic cylinder 25, and plunger promotes operating panel 35 by the operation of hydraulic pressure generation unit 41.So operating panel 35 is shifted to adapter plate 33, lock rope 3 again to allow, thereby stop the operation of elevator 1 in the same way.
Have backing plate 35a on the operating panel 35 of lock cell 31 and the surperficial relative one side of plunger 25a contact hydraulic actuating cylinder 25, backing plate 35a has a plurality of and elevator rope 3 contacted lock slots 35b.The front surface of the adapter plate 33 of lock cell 31 has backing plate 33a, and backing plate 33a has a plurality of lock slots 33b that trapezoidal cross-section arranged and it is fixed in adapter plate 33 with longitudinal direction.Therefore, because wedging action can remain in the failure-free lock-out state with being fixed in the lock slots 33b of backing plate 33a and 35a and the rope 3 between the 35b.
The operation of hydraulic pressure generation unit 41 that is used to operate driver element 21 is as follows.
With reference to Fig. 6, when elevator 1 is out of service, needs operation hydraulic actuating cylinder 25 and promote to be arranged on the plunger 25a of the front end of hydraulic actuating cylinder 25, thereby support elevator rope 3 securely by temporary transient big power.Operation by pump 42 comes compression working fluid, and working fluid passes to energy storage 44 by check valve 46, and prepares in energy storage and remain on the set pressure that is provided with by pressure switch 48.The working fluid of preparing with set pressure enters hydraulic actuating cylinder 25 through having the directed electromagnetic valve 45 of opening, and electromagnetic valve 45 can cut off the working fluid that flows to hydraulic actuating cylinder 25.The working fluid of Yin Ruing is effectively to operating panel 35 applied thrusts thus, and makes operating panel shift to adapter plate 33, thereby supports elevator rope 3 securely.Simultaneously, be contained in the working fluid outflow of 44 li of energy storages and flow to hydraulic actuating cylinder 25 simultaneously with set pressure.Therefore, the pressure decay that energy storage is 44 li, and also pressure switch 48 operating pumps 42 are until be full of set pressure in the energy storage.The working fluid that is flowed to energy storage 44 by pump 42 remains on accumulation state, thereby prepares for the operation subsequently of hydraulic actuating cylinder 25.
Working fluid is transported to hydraulic actuating cylinder 25 from energy storage 44, thereby allows the plunger 25a of hydraulic actuating cylinder 25 to promote operating panel 33.When directed electromagnetic valve 45 was powered, the counter flow pipe of directed electromagnetic valve 45 was opened by elevator operation restart signal.Therefore, the elastic force by spring 29 returns the operating panel 35 that is pushed to adapter plate 33, and pushes it against stay bearing plate 23, thereby in the plunger depressed 25a indentation hydraulic actuating cylinder 25.Working fluid returns jar 43 by the counter flow pipe of directed electromagnetic valve 45.
Even this elevator rope braking system also can be carried out brake operating during power fail, this is because energy storage 44 has kept the hydraulic pressure of predeterminated level.In other words, because power fail and when the direction of hydraulic actuating cylinder was opened, working fluid just was transferred to hydraulic actuating cylinder 25, energy storage 44 keeps the hydraulic pressure of predeterminated levels under this state when directed electromagnetic valve 45.Therefore, promote plunger 25a and pressing operation plate, thereby check elevator rope 3.
As mentioned above, the advantage of elevator rope braking system of the present invention is: thus the structure of having improved shell and adapter plate enough meets the temporary transient substantial load that takes place during the brake operating to the elevator rope abnormal motion, thereby improved the reliability of system.
And the advantage of elevator rope braking system of the present invention is by the direct pressing operation plate of the plunger of hydraulic actuating cylinder, thereby the mode of at high speed is braked the abnormal motion of elevator rope and elevator.
In addition, elevator rope braking system of the present invention adopts energy storage, thereby even also can carry out the elevator brake operation during power fail.
Though shown and first-selected embodiment of the present invention be described, be to be understood that the present invention is not limited to the detail of these embodiment, but limit by appending claims.
