Abstract

PURPOSE:To detect correct elevatable speed so as to improve safety and reliability of a self-running type elevator by providing a governor to adjust speed while being pressed against a guide rail and rotating on a carriage provided with a rolling wheel pinchedly held with the guide rail, on a supporting member through damper springs and damper devices. CONSTITUTION:A fixed frame body 21 having a U-shaped section is integratedly fixed to a horizontal supporting member 20 supporting one-side roller of an elevator car. A carriage 22 is provided on the fixed frame body 21 through a pair of upper and lower damper springs 23a, 23b and a pair of damper devices 24, and the carriage 22 is provided with a governor 25 of which the rotation member 26 is pressedly contacted to a guide rail 2 and rotated. Consequently, vibration or the like of the carriage 22 due to the elevator car is absorbed and dissolved through the damper springs 23a, 23b and the damper devices, and hence the elevatable speed of the elevator car can be correctly detected with the rotation member 26 of the governor 25 during elevatable movement of the cage, so as to improve safety and reliability.

2. Description of the Related Art In recent years, a skyscraper building has been constructed, and a conventional rope type (slave type) elevator is used as a transportation means for efficiently transporting a large number of personnel accommodated in this skyscraper building. A self-propelled elevator has been proposed instead.

An already proposed self-propelled elevator of this type is constructed as shown in FIG.

That is, as shown in FIG. 3, a guide rail 2 is erected on a side wall 1a of a hoistway 1 of a high-rise building, and the side wall 1a of the hoistway 1 on which the guide rail 2 is located. Has a primary coil 3 of a linear motor attached along the guide rail 2. Further, a car 4 is provided in the hoistway 1 at a position where the guide rails 2 face each other so that the secondary conductor 5 of the linear motor faces the primary coil 3 with each other. It is provided in. Further, a pair of brackets 6a and 6b are attached to the upper and lower portions of the car 4, and a holding member 7 having an inverted U shape is rotatably supported by a support shaft 8 on the one bracket 6a. It is axially mounted. Furthermore, a pair of guide rollers 9 are attached to the outside of the holding member 7 so as to sandwich both sides of the guide rail 2, and the speed governor 10 is mounted on the guide roller 9 on one side. It is connected via a transmission belt 11 so as to detect the speed of the car 4. An emergency stop device (also referred to as an emergency stop device) 13 is provided on the lower holding member 12 of each of the guide rollers 9.
Is provided so as to come into pressure contact with the guide rail 2 during braking during an emergency stop, and the guide rollers 9 and the emergency stop device 13 are held so as to rotate around the support shaft 8.

On the other hand, a U-shaped holding member 14 is rotatably mounted on a support shaft 15 on the other bracket 6b, and a pair of guide rollers 16 are provided outside the holding member 14. It is attached so as to sandwich both sides of the guide rail 2. A braking device 17 is provided outside the upper holding member 14 of each of the guide rollers 16 so as to apply a braking force to the guide rail 2 during braking, and the car on the opposite side of the braking device 17 is provided. In Fig. 4, a secondary-side conductor 18a made of a permanent magnet is laid horizontally facing the primary coil 18b of the linear motor attached to each floor. Further, as shown in FIG. 3, the passenger car 4 is provided with an opening / closing door 4a on the car side and an opening / closing door 19 on the landing side so as to open and close in synchronization with each other.

Therefore, in the above-described self-propelled elevator, when the car 4 is moved up and down along the guide rail 2,
The secondary conductor 5 of the linear motor of the car 4 is energized by operating the driving control panel (not shown) installed in the car 4 and pushing the push button to the desired floor, and this secondary The car 5 is raised or lowered by the conductor 5 and the primary coil 3 of the linear motor. Furthermore, while raising / lowering the car 4,
The speed governor 10 detects the rotation speed of the one guide roller 9 through the transmission belt 11 to detect the ascending / descending speed of the car 4. Further, when the car 4 is stopped on a predetermined floor, the braking device 17 brakes and brakes the guide rail 2 to land.

In particular, the governor of the self-propelled elevator described above is installed directly above the car 4, and
The guide roller 9 is rotated through the transmission belt 11 at a peripheral speed proportional to the speed of the car 4 and is rotated to detect the ascending / descending speed.

[0008]

However, the rotating member 10 of the speed governor 10 in the self-propelled elevator described above.
The rotation speed of a is determined by the slip of the guide roller 9 and the transmission belt 1.
Due to the bending of No. 1 or the like, the vibration of the car 4 is greatly affected, and it is difficult to accurately detect the ascending / descending speed. In addition, the car 4 is vibrated by the seams and gaps of the guide rails 2, and the rotating member 10a of the speed governor 10 is affected by the seams and gaps of the guide rails 2 to obtain accurate rotation. There is a problem such as not.

The present invention has been made in view of the above-mentioned circumstances, and is not affected by the vibration of the car, and the effect of the bending of the transmission belt is eliminated, so that the speed governor can be accurately moved up and down. (EN) A self-propelled elevator whose purpose is to detect speed and improve accuracy to improve safety and reliability.
