Embodiment Construction

[0015] figure 1 Portions of elevator system 20 including mounting assembly 22 are shown. Rails 24 provide support and direction for movement of mounting assembly 22 within hoistway 26 . The mount assembly 22 includes at least one first platform 28 movable along the guide rail 24 . In one example, the first platform 28 is a temporary platform used during installation. In another example, the first platform 28 is part of an elevator car frame, such as the platform that ultimately supports the car floor.

[0016] The second platform 30 is located below the first platform 28 (as shown in the figure). The second platform 30 is generally parallel to the first platform 28 . In one example, the second platform is a beam. A moving mechanism 32 is associated with the platforms and moves the first platform 28 and the second platform 30 along the guide rails. In this example, portions of the moving mechanism 32 are mounted to the platform 30 .

[0017] The first holding device 34 i...

Abstract

This invention generally relates to an assembly for moving a platform along guide rails within an elevator shaft during installation of an elevator system. The assembly includes a first platform, a first holding device, a second platform and a second holding device. The holding devices operate to allow movement in one direction and restrict movement in an opposite direction. A moving mechanism cyclically urges the first and second platforms toward and away from each other. The holding devices allow only one of the platforms to move at a time responsive to the cyclical urging of the moving mechanism. This is sequentially repeated until the first platform is in a desired position.

Description

technical field [0001] The present invention generally relates to a device for moving a car floor along guide rails in an elevator shaft during the installation of an elevator system. Background technique [0002] Elevator systems typically include guide rails extending vertically in the hoistway to guide the movement of the elevator car. The traction machine is supported near the top of the hoistway in a known manner. Typical installation procedures require the use of bottom chocks or car platforms supported in the hoistway to reach multiple heights within the elevator hoistway. Moving the known platform can be difficult and constant and make it difficult to complete certain parts of the installation process. [0003] It is often necessary to use an overhead crane or jack to lift the car bed, traction machine and other components to the desired position. In addition, some structures supported by buildings are often used as part of a safety crane. This measure increases ...
