Abstract

The invention discloses a frame type lifting device. The device comprises two main beams which are mutually parallel and are vertical to a walking guide rail, a walking vehicle which is arranged on the main beams and can walk along the main beam, and a crane which is arranged on the walking vehicle, wherein two supporting legs which are used for supporting the main beams and are formed into a certain included angle are respectively arranged at each end head of the main beams, the plane formed by the two supporting legs is parallel to the walking guide rail, and walking wheels are arranged at the bottom part of the supporting legs. Compared with the prior art, the device has the advantages that a frame type structure with large span and multiple supporting points belongs to a stable structure, and structure stability of the frame type lifting device is obviously improved; the overturn is difficult to generate, and the accident of the overturn can be effectively avoided when the lifting operation is carried out during assembly and molding.

Description

technical field [0001] This application claims the priority of the domestic application with the application number 201420293363.4 and the title of the invention "a frame-type hoisting device" submitted to the China Patent Office on June 4, 2014, the entire content of which is incorporated in this application by reference. Background technique [0002] As one of the most commonly used lifting equipment, gantry cranes are widely used in the storage of goods at stations, docks and open warehouses, etc. Handling work or handling and hoisting operations in the construction site. [0003] Gantry cranes generally adopt a door-shaped metal frame structure, and two legs are installed under the main beam, which can walk on the track installed on the ground. [0004] However, the structure of the gantry crane is not an absolutely stable structure, and vicious lifting accidents such as the overall instability and overturning of the equipment may occur during the application process, p...
