Light detachable movable portal frame device and using method thereof

Abstract

The invention provides a light detachable movable portal frame device. The portal frame device comprises a main beam, two triangular pyramid-shaped supports, connecting boxes, fixable universal wheelsand a pulley device, wherein the two triangular pyramid-shaped supports are located at the two ends of the main beam respectively, the main beam is connected with the upper ends of the two triangularpyramid-shaped supports through the connecting boxes, the fixable universal wheels are welded to supporting points of the lower parts of the triangular pyramid-shaped supports, and the movable pulleydevice is placed on the lower part of I-shaped steel of the main beam and moves in the length direction of the main beam. The invention further provides a using method of the device. By means of thedevice, articles can be moved in multiple directions on a construction site, moreover, the device can be disassembled into four parts for construction and field transfer, so that the problems of inconvenient transportation of objects, safety problems of repeated cutting and installation of a portal frame and the like on the construction site are solved.

Description

technical field [0001] The invention relates to a construction device in the technical field of construction engineering and a method of use thereof, in particular to a light-duty detachable movable gantry device and a method of use thereof. Background technique [0002] With the gradual advancement of China's urbanization, a large number of infrastructures are being built or planned to be built. During the construction process, the gantry, as an effective construction device for transferring large volumes and objects with a certain weight, has been widely used because of its wide adaptability and simple device. [0003] The gantry is divided into fixed type and movable type. The fixed gantry is mostly used to lift heavy objects and move along the beam direction of the gantry; the movable gantry is mostly a light gantry, and the movable gantry used in construction is mostly assembled by simple welding and can be used To hoist and transport some larger and lighter objects. ...
