Cantilever single-beam suspension, lifting and operation device capable of passing through curved rail belt

Abstract

The invention discloses a cantilever single-beam suspension, lifting and operation device capable of passing through a curved rail belt. The device includes a main beam, at least two rail camber beamsarranged in parallel, and a lifting cucurbit, the rail camber beams are arranged above the main beam and play a role in guiding the movement of the main beam, and the lifting cucurbit is arranged below the main beam; the main beam is provided with a travelling trolley which can move in the length direction, the lifting cucurbit is connected with and fixed on the travelling trolley, the main beamincludes a main beam body and main beam cantilevers, and the main beam cantilevers are arranged at least one end of the main beam body and extend in the length direction of the main beam; an underslung trolley is arranged between the main beam body and each rail camber beam so as to achieve the reciprocating movement of the main beam on the rail camber beams. A unique design structure is adopted,the underslung trolley replaces a traditional underslung end beam, the single side or two sides of the main beam body is / are provided with the main beam cantilevers, the whole device is more flexiblewhen passing through a curved rail, the operability is higher, and compared with the prior art, the device greatly expands the working area.

Description

technical field [0001] The invention relates to a hoisting and running device with a cantilever single beam suspension on a curved rail. Background technique [0002] Single girder suspension crane is a crane that suspends and fixes the main girder on the walking track (I-beam) of the building. It has been widely used in different places in various industries such as factory workshops and warehouses. In the prior art, the track beam traditionally used to install single-girder suspension cranes is directly fixed to the roof of the factory building by using two rolled I-beams. Suspension end beams are installed on the root track beams. Due to the large front and rear base distance of the suspension end beams and the rigid connection between the two ends of the main beam and the middle of the suspension end beams through high-strength bolts, the entire fuselage cannot rotate and cannot pass through the curved rail. , and because the two ends of the main girder of the crane are...

Problems solved by technology

In the prior art, the track beam traditionally used to install single-girder suspension cranes is directly fixed to the roof of the factory building by using two rolled I-beams. Suspension end beams are installed on the root track beams. Due to the large front and rear base distance of the suspension end beams and the rigid connection between the two ends of the main beam and the middle of the suspension end beams through high-strength bolts, the entire fuselage cannot rotate and cannot pass through the curved rail. , and because there is no cantilever structure designed at both ends of the main girder of the crane, the scope of work is reduced to a certain extent. The structure design of this crane is too rigid, the operability is not strong, and its application range is limited
