Moveable hoisting machine and construction method thereof

Abstract

The invention discloses a moveable hoisting machine and a construction method thereof, belonging to the technical field of engineering machinery. The moveable hoisting machine of the invention comprises a top beam; a driving device is fixed on the top of the top beam, and is in transmission connection with a rotating seat through a transmission shaft; four lifting arms are fixed on the peripheralside surface of the rotating seat; one end of the transmission shaft penetrates the top beam and is rotatably connected with the top beam; the top of the top beam is fixedly provided with a support turntable; the top of the support turntable is connected with a revolution turntable through a revolving member; the peripheral side surface of the transmission shaft is provided with a flange; the transmission shaft is fixedly connected with the revolution turntable through the flange; the top end of the transmission shaft is fixedly provided with a fluted disc; and the bottom end of the transmission shaft is in flanged joint with the rotating seat. The moveable hoisting machine of invention can carry out revolving motion on the top beam in virtue of the rotating seat, and as the retractable lifting arms are arranged at different directions of the rotating seat, the moveable hoisting machine has the functions of revolution, retraction and multi-point simultaneous working; thus, the moveablehoisting machine has the advantages of a wider working range, higher working efficiency, stronger hoisting capacity and better flexibility in use.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a movable hoisting machine and a construction method thereof. Background technique [0002] Hoisting machinery, also known as a crane, refers to a multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. Cranes mainly include hoisting mechanism, operating mechanism, luffing mechanism, slewing mechanism and metal structure. The hoisting mechanism is the basic working mechanism of the crane, mostly composed of a suspension system and a winch, and also lifts heavy objects through a hydraulic system. The operating mechanism is used to move heavy objects vertically and horizontally or adjust the working position of the crane, and is generally composed of a motor, a reducer, a brake and wheels. The luffing mechanism is only equipped on the jib type crane. When the jib is raised, the range decreas...
