AI Technical Summary

Technical Problem

Existing hoisting technologies cannot vertically hoist building materials with protruding structures to the target floor, and inclined hoisting methods pose safety risks.

Method used

Design an adjustable counterweight balancing lifting device, including a lifting frame and a counterweight. One side of the lifting frame forms a cantilever beam, and the counterweight is installed on the side away from the cantilever beam. The counterweight is driven to slide along the slide rail by an electric winch and a wire rope to adjust the lifting balance and ensure that the cantilever beam is in a horizontal state when lifting materials.

Benefits of technology

It enables safe and efficient horizontal hoisting of materials in raised structure buildings, avoids spatial conflicts, improves hoisting efficiency and safety, and adapts to the construction needs of different raised structures.

Abstract

The utility model relates to a kind of adjustable counterweight balance lifting appliance, belong to hoisting equipment technical field, to solve the problem that the building hoisting material with protruding structure in prior art, using vertical hoisting mode exists material cannot be transferred to target floor, and using skew way exists security risk problem.The present application includes hoisting frame and counterweight, and the side frame body of hoisting frame extends along horizontal direction outward, forms a cantilever beam;Counterweight is installed in the hoisting frame far from cantilever beam;To be hoisted object is installed in the cantilever beam of hoisting frame, when hoisting frame is hoisted by hoisting equipment, cantilever beam is hoisted under the gravity of counterweight, to hoist to-be-hoisted object in horizontal state.The present application installs to-be-hoisted object by the cantilever beam of hoisting frame, and the other side hoisting frame far from cantilever beam is installed with counterweight, so that when hoisting, hoisting frame drives to-be-hoisted object and counterweight are hoisted together, cantilever beam is in horizontal state, to-be-hoisted object is placed in target floor from side, and construction efficiency is high and construction safety is good.
