Abstract

The invention provides a step hoisting device of a heavy object, wherein the step hoisting device can easily perform rail height adjustment on the condition that a hoisting trolley and a chain block are mounted on a rail. The step hoisting device is provided with the components of a door-shaped auxiliary clamp (50) which includes a front door-shaped component with telescopic front columns (2a,2b) and a front connecting component (4a), a back door-shaped component which is provided with telescopic back columns (3a,3b) and a back connecting component (4b), a rail (5) which is connected with the front connecting component (4a) and the back connecting component (4b), the hoisting trolley (7) which is movably mounted on the rail (5), and a main chain block (8a) for hoisting the heavy object (10); platform parts (11a,11b) which carry the heavy object (10); rollers (12a,12b) which are mounted below the platform parts (11a,11b); and supporting legs (13a,13b) which can adjust the platform parts (11a,11b) to a horizontal state. Furthermore the step hoisting device is provided with a height adjusting device (51) which can adjust the height of the back columns (3a,3b) of the back door-shaped component.

Description

technical field [0001] The present invention relates to a step lifting device and a step lifting method for lifting heavy objects such as a traction machine of an elevator via steps. Background technique [0002] In the reconstruction construction of the elevator, for example, it is necessary to lift the traction machine and the control panel to the platform of the machine room provided with the elevator installed on the roof of the house via the steps of the house. For example, currently, a new traction machine is conveyed through passages and steps using the technique disclosed in Patent Document 1. [0003] In recent years, the technology of a step lifting device has been developed as a device for easily performing these lifting operations. In the step lifting device, a door-shaped lifting device is installed on the steps, and the traction machine is lifted by the door-shaped lifting device. However, in the door-shaped lifting device, in order to ensure the hoisting capa...
