Description

Balance weight and elevator Technical Field The present invention relates to a balance weight and an elevator provided with the balance weight. Background The bucket elevator is connected with the car and the balance weight through a sling, and the balance of the weight of the car and the balance weight is obtained to balance the weight. This reduces the load applied to the hoisting machine around which the hoisting rope is wound. In an elevator in which the mass of the car is large, it is necessary to increase the mass of the balance weight. In order to increase the mass of the balance weight, it is considered to use a weight having a large specific gravity or to increase the weight of the balance weight to increase the number of weights to be loaded. However, since the weight having a large specific gravity is expensive, the cost of the balance weight increases when the weight having a large specific gravity is used. Patent document 1 discloses an elevator counterweight frame structure including a vertical frame, an upper side plate provided on an upper portion of the vertical frame, and a lower side plate provided on a lower portion of the vertical frame. The elevator counterweight frame structure forms a first receiving portion between a pair of first longitudinal frames and a second receiving portion between a pair of second longitudinal frames. Further, weights are mounted in the first accommodation portion and the second accommodation portion. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2009-215034 Disclosure of Invention Problems to be solved by the invention However, the elevator counterweight frame structure disclosed in patent document 1 is not provided with an emergency stop device. The emergency stop device is usually provided at the lower part of the frame of the balance weight. Therefore, in the case of providing the emergency stop device, it is difficult to load the counterweight at the lower portion of the housing. In view of the above, an object of the present invention is to provide a counterweight and an elevator having the counterweight, which can ensure a space for loading the counterweight at the lower part of a housing even when an emergency stop device is provided. Means for solving the problems In order to solve the above problems and achieve the object, a counterweight according to the present invention includes a frame that moves guided by a guide rail provided in a hoistway, a plurality of first counterweights disposed in the frame, a brake mechanism, a lifting mechanism, and a lifting mechanism mounting member. The braking mechanism is connected with the frame body and provided with a braking piece, and the braking piece is lifted to clamp the guide rail so as to stop the movement of the frame body. The lifting mechanism lifts the brake. The lifting mechanism mounting member mounts the lifting mechanism to the frame and holds the second counterweight. In addition, the elevator of the present invention drives the elevator car and the counterweight connected by the sling in different directions. ADVANTAGEOUS EFFECTS OF INVENTION According to the counterweight of the above-described structure, even when an emergency stop device (brake mechanism and lift mechanism) is provided, a space for loading the counterweight at the lower portion of the housing can be ensured.
