Problems solved by technology

As a result, even if it is an elevator component with a weight of about 30 kg, it can be lifted relatively easily on the ground where a free posture can be taken, but it becomes difficult to lift it near the top of the elevator passage.
In this way, the burden on the operating personnel is very heavy, and it is undeniable that the operating efficiency is greatly reduced.

no. 1 approach

[0027] like figure 1 As shown, a building B as a structure has an elevator passage 1 . A guide rail 2 for guiding the elevator car to go up and down is arranged inside the hoistway 1 . The guide rail 2 is erected vertically along the lifting passage 1. A bracket 3 is fixed on the wall of the lifting passage 1 , and the guide rail 2 is supported on the bracket 3 through a plurality of rail clamps 4 .

[0028] The top 2 a of the guide rail 2 is close to the ceiling surface 1 a of the lift passage 1 . A pulley device 7 is mounted on the top 2 a of the guide rail 2 . The pulley unit 7 has a first support plate 8, a second support plate 10, and a pair of pulleys 11a, 11b.

[0029] like figure 2 As shown, the first support plate 8 extends perpendicularly to the guide rail 2 in the horizontal direction. The first support plate 8 is made of, for example, an angle steel having an L-shaped cross section having a horizontal plate 8 a and a vertical plate 8 b. The second support p...

no. 3 approach

[0056] According to the third embodiment of the present invention, the lateral movement of the tether part 18 is restricted by the guide member 35 which moves along the guide rail 2 . Therefore, swinging of the tether member 18 when the tether member 18 is pulled up along the lifting passage 1 can be suppressed. In this way, the tether member 18 can be hoisted safely to the vicinity of the top of the lifting passage 1 in a stable posture.

[0057] Figure 7 A fourth embodiment of the present invention is shown.

[0058] In the fourth embodiment, the first pulley unit 7 is attached to the top portion 2a of the guide rail 2 by the screw jack 23 similar to the second embodiment. The first pulley device 7 basically has a structure similar to that of the pulley device 7 of the first embodiment.

[0059] Specifically, the first pulley unit 7 has a pulley 11a at one end of the first and second support plates 8,10. The pulley 11a is rotatably supported by the first and second supp...

Abstract

A lifting device has a sheave device (7) having rotatable sheaves (11a, 11b) and installed in a hoistway (1), and also has a hoist (14) installed in the hoistway (1) at a position below the sheave device (7) and having a lifting rope (16) capable of being paid out and drawn in. The lifting rope (16) paid out from the hoist (14) into the hoistway (1)is guided to the lower side of the sheave device (7) via the sheaves (11a, 11b). An elevator component (18) to be installed in the hoistway (1) is connected to the paid out end of the lifting rope (16). The elevator component (18) is lifted along the hoistway (1) by drawing the lifting rope (16) into the hoist (14).

Description

technical field [0001] The present invention relates to a hoisting device used when installing components for an elevator such as rope hitches in, for example, a hoistway of a building. Background technique [0002] When an elevator is installed in an elevator passage of a building, various parts for elevators are attached to the elevator passage. As components for an elevator, various components such as a hoist for driving a car, various pulleys, and tether components are known. Among them, regarding a heavy object weighing more than 100Kg such as a hoist, in consideration of work efficiency during installation, a dedicated hoisting device such as that shown in JP 2004-331348 A is used to hoist in the lifting passage. [0003] On the other hand, with regard to components for elevators that are lighter than a hoist, installation work is currently performed by a worker's human power. However, even among the light elevator parts, some elevator parts weigh more than 40 kg. I...
