Device for directly hoisting object into house through tower crane

Abstract

A device for directly hoisting an object into a house through a tower crane comprises a case, a suspension arm, a bracket, a balance arm, a balance weight, sliding seats, a reel and a motor. The suspension arm and the balance arm are mounted in the case. Slideways are arranged below the suspension arm and the balance arm, and the sliding seats are mounted on the slideways. Goods are hoisted on thesliding seats. The tower crane hoists middle of the upper portion of the case. When the goods are about to be hoisted into the house on a built floor, the tower crane hoists the device and the hung goods to move to the front of a window of the target house. Specially-assigned persons in the target house and a tower crane driver are in wireless contact and cooperate for operation. The suspension arm stretches forwards into the house from the window, meanwhile, the balance arm stretches out of the rear portion of the case, and the two ends of the case are kept balanced. The suspension arm stretches out in place. The bracket at the front end of the suspension arm is placed off to a floor. The sliding seats are controlled by a worker in the house to slide to the front end of the suspension arm, and the goods are placed to touch down. The balance arm only balances the stretching process of the suspension arm, and the weight of the goods is not balanced. The tower crane can directly hoist building materials into the house through the device without a transferring platform. The workload and the building cost are reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of equipment for hoisting and transporting objects, in particular to a device for directly hoisting objects into a house by a tower crane. Background technique [0002] Nowadays, tower cranes are widely used in building construction sites to lift building materials. But existing tower crane all can not directly lift building material on the floor in each floor of building, all will use a transshipment platform as building material transfer point. The transfer platform should be designed in advance, and the corresponding steel bars should be pre-embedded when pouring concrete to build the transfer platform. The transfer platform is large and overhangs the floors. The tower crane can lift steel bars, cement, sand, stones, bricks, formwork, prefabricated parts, etc. on the transfer platform, and then manually transport these materials to the upper and lower floors, and transport them to the corresponding room floor for...
