AI Technical Summary

Technical Problem

In construction environments with limited space or enclosed structures, such as indoor spaces, basements, pipe shafts, and equipment rooms, traditional large hoisting equipment has difficulty entering, resulting in low construction efficiency and even making it difficult to complete hoisting tasks.

Method used

An indoor prefabricated hoisting device for building engineering is adopted, including components such as a base support, threaded jack, support structure, fixed column, I-beam, locking mechanism, winch and traction rope. By combining these components, height adjustment, structural locking and hoisting operations can be achieved, adapting to narrow spaces and pipes of different sizes.

Benefits of technology

It enables efficient hoisting in confined spaces, is lightweight and reusable, adapts to different power conditions at construction sites, and improves construction efficiency and safety.

Abstract

This utility model discloses an indoor prefabricated hoisting device for building engineering, including a base support. A bearing pipe is installed on one side of the upper end of the base support, and a threaded jack is installed inside the bearing pipe. A support structure is installed on the upper end of the threaded jack, and a fixed column is installed on the upper end of the support structure. A top plate is fixed to the upper end of the fixed column, and an I-beam is threaded through the fixed column. A locking mechanism is installed on the I-beam, and pulleys are installed on both sides of the lower end of the I-beam. This utility model facilitates manual handling and on-site relocation, is suitable for operation in confined spaces, and is applicable to both electric winch hoisting and manual hoist hoisting. It adapts to the power conditions of different construction sites, has an adjustable hoisting arm to accommodate pipes of different diameters and lengths, and possesses high flexibility. The device components are reusable and are suitable for areas that are difficult for traditional hoisting equipment to access, such as indoor spaces, basements, pipe shafts, and equipment rooms.
