Problems solved by technology

[0006] However, in the elevator device disclosed in the above-mentioned Patent Document 1, since the structure of the counterweight is complicated, it is difficult to manufacture, and if a plurality of elevators are to be installed, a special counterweight must be installed on each elevator.
Moreover, it is difficult to apply the special counterweight of the above-mentioned Patent Document 1 to an existing elevator having a normal counterweight.

Embodiment Construction

[0046] Embodiments of the present invention will be described below with reference to the drawings.

[0047] figure 1 It is a plan sectional view of the hoistway 1 of the elevator apparatus in the first embodiment of the present invention. The elevator device of the present embodiment is constituted such that there are an elevator car 2, a counterweight 7, and a winch (not shown) in the hoistway 1, the elevator car 2 and the counterweight 7 are suspended by the main rope 4, relying on the hoist The driving force of the drive sheave 5 moves up and down.

[0048] Here, the main rope 4 is configured to extend upward from the main rope fixture 3 provided on the elevator car 2 , pass through the drive sheave 5 , be wound around the guide pulley 6 and extend downward to reach the Main sling fixture 8 on counterweight 7. In addition, as the main rope 4 or the driving sheave 5 in this embodiment, a material covered with resin may be used, for example, other than steel. In addition...

Abstract

The invention provides an elevator device capable of operating the confirmation of action of emergency brake device and testing method thereof. In the method of the elevator according to the invention, the reduction of the cage of the elevator can be restrained even when the drive loop wheel (5) of the windlass is in state of rotating, thus action confirmation is operated to the emergency brake device (23) of said elevator cage (2), wherein, in state that recover force generating mechanism generates deformation because of the reduction of the balance weight (7), the drive loop wheel (5) of the windlass rotates in lifting direction of said balance weight (7).

Description

technical field [0001] The present invention relates to an elevator having an elevator car and a counterweight, and particularly relates to a technique suitable for confirming the action of an emergency braking device. Background technique [0002] In many elevator systems, the elevator car and the counterweight are connected by a main rope, and a hoist is provided, and the hoist is equipped with a drive sheave near the middle of the elevator car and the counterweight. In addition, the elevator system is configured such that the main rope is wound around the drive sheave, and the elevator car and the counterweight are moved up and down by rotating the drive sheave. Therefore, an emergency braking device is installed in the elevator car in order to be prepared in the event of an abnormal situation such as the breakage of the main rope. [0003] In the above-mentioned elevator system, when checking the operation of the installed elevator emergency braking device, the test is ...
