Embodiment approach 1

[0111] (1. Outline of the lifting device 100)

[0112] In Embodiment 1, an elevator hoisting device for hoisting a heavy load in an elevator hoistway will be described. figure 1 It is a figure explaining the disadvantage of the case of directly lifting the heavy object 1 which is a lifting object. figure 2 It is a figure explaining the structure of the lifting apparatus 100 of this Embodiment 1. figure 2 Indicates after the upgrade is complete.

[0113] Such as figure 1 As shown, in the case of lifting a heavy object 1 (such as a tractor), when temporarily installing a crane 3 (such as a winch) on the ceiling of the hoistway 5 (shaft top 5a) and hoisting the heavy object 1, for the heavy object 1. It is equivalent to the height of the crane 3 itself (lifting margin H 2 ) cannot be increased. Therefore, there are cases where the size of the hoistway becomes longer by an amount equivalent to the lifting margin H 2 . In Embodiment 1, for not using the boost margin H 2...

Embodiment approach 2

[0194] In Embodiment 1, the crane main body 30 is installed in the hoistway top 5a. On the other hand, in Embodiment 2, the case where the crane main body 30 is installed in the car frame 7 is demonstrated.

[0195] Figure 18 It is a figure which shows the case (Embodiment 1) in which the crane main body 30 is installed in the hoistway ceiling 5a. in comparison, Figure 19 It is a figure which shows the state where the crane main body 30 is attached to the car frame 7. As shown in FIG. also, Figure 20 with Figure 21 It is a perspective view of a case where the crane main body 30 is attached to the car frame 7 . Figure 20 with Figure 9 correspond, Figure 21 with Figure 11 correspond. Such as Figure 20 or Figure 21 As shown, the crane main body 30 is attached to the car vertical column 7 b of the car frame 7 . That is, in Figure 20 or Figure 21 Among them, the crane main body 30 has a chain 35a whose end is a hook (not shown). This hook is hooked to the...

Abstract

A lifting device 100 comprising a guide rail 8 that is arranged from a lower portion 81 to the top portion 51 of the hoistway 5; a car frame of elevator 7 that is capable of going up and down, guided by the guide rail 8, by providing a guide shoe 9 engaging with the guide rail 8, and that is used as a platform placing the weight 1 for lifting to the vicinity of the top portion 5a of the hoistway 5; and a lifting machine 3 that lifts the car frame 7 placing the weight 1 to the top portion 5a, guided by the guide rail 8. Based on this, a labor of tool dismantling can be eliminated.

Description

technical field [0001] The present invention relates to an elevator hoisting device for hoisting heavy objects in an elevator hoistway, an elevator car frame and an elevator hoisting method. Background technique [0002] When assembling elevator equipment, the size of the hoistway must not only accommodate the assembled equipment, but also consider the space necessary for installation work during the assembly process to determine the size of the hoistway. In particular, when the elevator equipment is carried into the hoistway and raised to a predetermined height, it is of course necessary to ensure the carrying path, but it is also necessary to secure a space in the hoistway for cargo handling and lifting allowance. Here, the "lifting margin" refers to the height of the crane, more precisely, refers to the installation space including the height of the crane. [0003] For example, in the case of using chain pulleys to lift equipment, when lifting the weight of equipment of ...
