Raising cage used for swinging concrete by helicopter

Abstract

The invention provides a raising cage which is used for swinging concrete by a helicopter, comprising a lifting lug, a tank body, an unloading mechanism and a bracket. The tank body is divided into three sections, wherein the upper section is a cylinder, lower section is a cube, the cross section at the upper end of the middle section is circular and the cross section at the lower end is quadrate, and the middle part adopts variable cross-section to transit; the unloading mechanism is installed at the bottom of the tank body and uses gears for mesh type transmission, thus meeting the opening and closing of a single person at a single side or multiple persons at double sides; the lifting lug is welded on the top of the tank body, is connected with the top of the tank body through a sling dedicated for the helicopter and can hang the tank body below the belly of the helicopter; and the bracket is a frame structure which is welded by the structural steel and is connected with the tank body through a cotter pin or a bolt. The raising cage in the invention has the advantages of simple structure, light weight, large accommodation capacity, flexible opening and closing mechanism, convenient unloading, stable swinging and the like, can give full play to the plug-in swinging capacity of the helicopter, can be used as a standardized construction tool of electric power construction swinging concrete and meets the requirements of swinging the concrete by helicopters.

Description

technical field [0001] The invention belongs to construction equipment for tower foundations of overhead transmission lines in power grid construction, and in particular relates to a hanging tank used for lifting and transporting concrete by helicopter. Background technique [0002] Concrete foundation has high compressive strength and is a commonly used foundation form for overhead transmission line towers. The concrete required for the concrete foundation is usually mixed manually or mechanically on site, and cast immediately. The mixing efficiency is low, the labor intensity is high, and the quality of the concrete is not easy to guarantee. Especially for high-voltage transmission lines that pass through mountains and ridges, the total amount of concrete required for the tower foundation is large, and the transportation of materials and equipment is very difficult. At this time, it is difficult to meet the construction needs if the concrete is still mixed manually or mech...

Problems solved by technology

The concrete required for the concrete foundation is usually mixed manually or mechanically, and poured immediately. The mixing efficiency is low, the labor intensity is high, and the quality of the concrete is not easy to guarantee.

Especially for high-voltage transmission lines that pass through mountains and ridges, the total amount of concrete required for the tower foundation is large, and the transportation of materials and equipment is very difficult. At this time, it is difficult to meet the construction needs if the concrete is still mixed manually or mechanically on site.
