Method for conveying large-size prefabricated concrete flue through hoistway type construction hoist

Abstract

The invention discloses a method for conveying a large-size prefabricated concrete flue through a hoistway type construction hoist. The method comprises the following steps that machining and manufacturing a special cart; loading the prefabricated concrete flue onto the special cart; pushing the special cart for loading the prefabricated concrete flue to a door opening of the construction hoist, and operating the special cart to move the prefabricated concrete flue into a car of the construction hoist; and starting the construction hoist to lift the special cart loaded with the prefabricated concrete flue to a specified floor. The invention is novel in design, convenient to use and easy to operate, the rotating connection position of a pin shaft between the upper end of a front oblique beam and a rectangular bracket is the balance gravity center point after the prefabricated concrete flue is loaded, and the special cart is used for changing the posture of an object in the conveying process; the purpose of conveying the prefabricated concrete flue through the construction hoist is achieved under the condition that the gravity center of an object is not changed, and the advantages ofrapidness, convenience, labor saving and safety are achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction machinery and equipment, and in particular relates to a method for transporting a large-volume prefabricated concrete flue by a hoistway type construction elevator. Background technique [0002] There is a kind of prefabricated concrete flue in the construction. This kind of prefabricated concrete flue is large in volume and heavy in weight. After the overall production of this prefabricated concrete flue is completed in the production plant, the whole prefabricated concrete flue is transported to the design installation site. The prefabricated concrete flue is 2850mm long, 600mm wide, 400mm high, and weighs 150kg. The existing construction method is to use 4 laborers to manually carry it into the construction elevator car. Because the construction elevator car door opening is 2000mm high and 900mm wide, manually carrying this prefabricated concrete flue has a long construction perio...

Problems solved by technology

The existing construction method is to use 4 laborers to manually carry it into the construction elevator car. Because the construction elevator car door opening is 2000mm high and 900mm wide, manually carrying this prefabricated concrete flue has a long construction period and low efficiency. It is a waste of time to occupy the construction elevator for a long time
