The present invention relates to a governor of an elevator apparatus, and in particular, is provided on an upper surface of an elevator car, and provided with a shield switch solenoid for returning the shield switch, and a pole return for automatic return of the secondary braking means, The brake rope directly operates the link mechanism of the emergency braking system, and is provided with a braking means for opening and closing the vehicle, and is configured to perform forced braking for speeding in both directions ascending and descending. The follow-up work for the return of the braking device following the forced stop of the elevator is completed by the simple operation of applying the switch of the solenoid, which makes the maintenance of the elevator easier and easier.

The present invention relates to an overspeed governor of an elevator device that prevents a safety accident due to an opening and closing and to ensure that the safety of an elevator is remarkably strengthened by a forced braking performed at the same time as a sudden descent.

In general, as shown in Fig. 1, the elevator apparatus is composed of a machine room, a hoistway, an elevator car 2, a main rope 3 and the like. The machine room located at the top is provided with a main power control unit, a hoist, an electric motor and a governor 10, and an elevator car 2, a guide rail 5, a main rope 2, a governor rope 11, and emergency braking. An apparatus 4 or the like is installed, and a shock absorber is positioned at the bottom.

The elevator device is a safety device for preventing the fall of the elevator car 2, which is installed in the machine room above the elevator car lift path to detect the speed of the elevator, and stops the descending of the elevator car 2 when the speed increases beyond the rated speed. A governor 10 is provided to cut off the power of the hoisting machine and to operate the link mechanism 6 connected to the emergency braking device 4 at one side of the elevator car.

The governor 10 is the governor rope 11 is wound between the tension sheave 13 provided on the lower side, one side of the governor rope 11 is coupled to the link mechanism 6 connected to the emergency braking device (4) The tension sheave 13 has a tension weight 14 mounted on the lower side thereof, and the tension sheave 13 and the tension weight 14 are linked to the lower side of the guide rail 5 so that the governor ( The length of the governor rope 11 wound between 10) and tension sheave 13 can be flexibly adjusted.

FIG. 2 is a partial cutaway front view showing the configuration of the governor 10 of the prior art, and FIG. 3 is a plan view of FIG.

As shown in Figures 1 to 3, the governor 10 of the prior art is installed in the machine room, rotatably installed in the frame 15, the main sieve 12, the governor rope 11 is wound on the outer peripheral surface And a pair of flyweights 12a provided on the main sieve 12 so as to be opened by the centrifugal force when the main sieve 12 is speeded above the set speed, and a pin coupling on the circumferential surface of the main sieve 12. The outer circumferential surface of the main sieve 12 while the pole member is in contact with the pole 16a installed while being elastically supported by the finger member and the flyweight 12a to interlock the pole 16a by the centrifugal force of the flyweight 12. And a ratchet 16 interlocked with the main sieve 12 according to the trip lever 16b installed on the main shaft 12 and rotatably installed on one central axis of the main sieve 12 and engaged with the pawl 16a. The governor rope 11 is coupled to one side of the 16 through a link and in accordance with the rotation of the ratchet 16. Pressing the rope fixture 17 for fixed, is actuated by the centrifugal force of the fly-weight (12a) includes a shield switch 18 which cuts off power to the traction machine (not shown).

The rope fixing body 17 is a rope catcher 17a rotatably coupled to a frame, a pressing member 17n for applying an external force to the rope catcher 17a, and an elastic force for applying the pressing member 17b. It consists of a holding member 17c and a link 17d.

The governor 10 of the prior art having such a configuration is sequentially performed according to the following two operations.

In the first operation, when the speed of the elevator car reaches 130% of the static speed, the power supply is stopped to cut off the power supply of the hoisting drive motor, and at the same time, the hoisting brake is operated to stop the electric drive of the elevator apparatus.

In other words, when the elevator car moves up and down by more than 130% of the set speed, as the coarse sheave 12 of the governor also rotates at the same time, the flyweight 12a is opened by centrifugal force. By touching the flyweight 12a, the shielding switch 18 is touched, and the power of the hoisting machine is cut off to stop the operation.

In the second operation, when the speed of the elevator car reaches 140% of the rated speed, the flyweight 12a attached to the side surface of the main sieve 12 is subjected to the centrifugal force due to the overspeed rotation following the first operation. By operating the trip lever 16b and the pawl 16a is interlocked to drive the ratchet 16, and at the same time the rope fixing body 17 which is integrally connected to the ratchet 16 to operate the governor rope 11 The deceleration stop stops the lowering of the elevator car. Subsequently, following the second operation, the emergency braking device 4 at the lower end of the elevator car 2 is operated to grasp the guide rail 5 with a strong force to stop the sudden descent of the elevator car.

In other words, the flyweight 12a moves the trip lever 16b by overspeed rotation of the main sieve 12, thereby moving the pawl 16a fixed on the trip lever 16b to engage the ratchet 16. do.

By the engaging action of the pawl 16a and the ratchet 16, the ratchet 16 is constrained to the coarse sheave 12, so that the ratchet 16 is also rotated in the same direction as the coarse sheave 12 rotates, Accordingly, the ratchet 16 pulls the link 17d of the rope fixing body 17 so that the rope catcher 17a is in close contact with the governor rope 11 so that the movement of the governor rope 11 is blocked.

Accordingly, the link mechanism 6 and the emergency braking device 4 are operated to perform emergency braking of the elevator car.

However, the governor 10 of the related art has the following problems.

First, since the governor 10 is installed in the machine room on the upper side of the elevator path of the elevator device, the manager has to climb up to the machine room located in the place for repair and management.

Second, in order to return the shielding switch 18 which has turned off the driving power of the hoisting machine by the primary braking operation, the operator must raise the shielding switch lever of the governor directly, thereby inevitably climbing to the machine room in which the governor is installed. .

Third, the rope fixing body is engaged when the pole 16a is engaged with the ratchet 16 and the rope fixing body 17 is operated by the secondary braking operation so that the elevator car 2 is driven again after the action in the emergency stop state. In order to restore the original (17) and the pole (16a), there was a difficulty that the operator had to go up to the machine room where the governor was installed and take a return action.

Fourth, there was a problem that the governor does not operate even when the elevator car is lifted in the open door.

Fifth, in the case of the secondary braking, the emergency stop is possible only when the elevator car descends due to the configuration of the ratchet, and thus, the safety device against the speed increase is lacking.

Sixth, after the governor rope 11 wound on the main sieve 12 is fixed by the rope fixing body 17, the structure for braking the emergency braking device by the link mechanism 6 connected on the governor rope again; Due to the operation relationship, not only the connection relationship and the operation relationship is very complicated disadvantage, the installation work is also very cumbersome, it is not easy to replace and repair in the event of a failure, the rope fixing body 17 is installed on one side There is a fear that the member 17c may be bent, and thus there is a problem in that the braking action of the governor rope 11 does not give confidence.

In addition, since the main sieve 12 and the tension sieve 13 are respectively installed on the upper and lower sides of the hoistway, the governor rope is wound up, thus requiring a lot of installation space and using an expensive governor rope. Therefore, there was a problem that the cost of the facility is increased.

The present invention has been devised to solve the above problems,

An object of the present invention is provided on the upper surface of the elevator car, and provided with a shield switch solenoid for returning the shield switch and a pole returner for automatic return of the secondary braking means, and the braking rope of the secondary braking means is connected to the emergency braking device. By operating the mechanism directly and equipped with a braking means for opening and closing, and configured to be forced braking for the lifting bi-directional speed,

There is no need to go up to the machine room located at the height of the elevator, and the follow-up work for the return of the braking device following the forced stop of the elevator is completed by the simple operation of applying the switch of the solenoid. Easily done,

It is to provide a governor of an elevator device that prevents safety accidents caused by the opening and closing of the elevator and assures the safety of the elevator is remarkably strengthened by the forced braking in the same way as the sudden descent.
