Abstract

The invention relates to a trackless gantry crane. The trackless gantry crane comprises a crane rack (1) consisting of a main girder (1b) and a gantry frame (1a), wherein a sling (3) is arranged just under the main girder. The trackless gantry crane is characterized in that sliding arm frames (6) are respectively arranged at symmetrical parts on two sides of the top of the crane rack, sliding arms (5) in sliding fit with the sliding arm frames are arranged on the sliding arm frames, horizontal pulleys (7) are respectively arranged at two ends of the sliding arms, a vertical pulley (8) is also arranged on the main girder on one side of each horizontal pulley, the main girder is also provided with a hydraulic cylinder (9), two ends of the hydraulic cylinder are respectively connected with the middle part of the sliding arm on the sliding arm frame on the corresponding side, a pair of steel wire ropes (4) is respectively arranged at symmetrical parts on two sides of the sling, one ends of the steel wire ropes are connected to the sling, and other ends of the steel wire ropes sequentially pass by the vertical pulleys and the horizontal pulleys to be fixed on the main girder. The trackless gantry crane provided by the invention has the advantages of simple structure, and convenience in operation, and a pushing device with less occupied space is used for replacing an electric hoist or a winch for lifting, so that tunnel space is vacated.

Description

technical field [0001] The invention relates to a hoisting and transporting device for a shield tunnel, in particular to a trackless gantry crane. Background technique [0002] Before the existing gantry cranes are put into operation in the shield tunnel, temporary tracks need to be laid in the tunnel for the operation of the cranes. This makes the space of the tunnel with limited space even tighter, and the existing gantry cranes often use electric hoists or hoists for hoisting, both of which need to occupy a larger tunnel space. Contents of the invention [0003] The object of the present invention is to solve the problem that the gantry cranes in the prior art occupy a large space in the tunnel, and provide a trackless gantry crane that makes full use of the space. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A trackless gantry crane, including a crane frame composed of a main girder and a gantry frame. ...
