Gantry crane for large special equipment

Abstract

The invention provides a gantry crane for large special equipment, and relates to the technical field of gantry cranes. The gantry crane comprises two slide rail fixing frames, two parallel triangular slide rail trusses penetrate through the two slide rail fixing frames, and two transverse moving turntables are rotationally connected through a transverse moving chain belt; and the lower end of a lifting assembly is movably connected with a hook claw assembly used for grabbing objects. A motor driving bevel gear on an adjusting box motor rotating output shaft is meshed with a synchronizing shaft bevel gear to drive an adjusting synchronizing shaft to rotate, so that synchronous rotating gears at the two ends rotate at the same time, four adjusting claw hook supporting rods at the two ends are driven to stretch out and draw back, and therefore the distance between two hook claw frames at the lower end can be adjusted, and aim of adjusting the object hooking length can be achieved. Compared with an existing gantry crane frame, the gantry crane has the advantages that when large containers are hooked, due to the fact that the sizes of the containers are different, stress in the vertical direction of the hook claws is more sufficient by adjusting the length of the hook claws.

Description

technical field [0001] The invention relates to the technical field of gantry hammocks, in particular to a gantry hammock used for large-scale special equipment. Background technique [0002] At present, the gantry crane, also known as the gantry crane, is a deformation of the bridge crane, which is mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can walk directly on the track on the ground. The two ends of the main beam can have outrigger cantilever beams, which have high site utilization rate, large operation range and wide adaptability. , Versatility and other characteristics. [0003] Nowadays, the flow of maritime logistics is gradually increasing, and the logistics objects are also various. When the current gantry cranes deal with various objects, they can only be trapped on each uniform bearing point on the object...

Problems solved by technology

[0003] Nowadays, the flow of maritime logistics is gradually increasing, and the logistics objects are also various. When the current gantry cranes deal with various objects, they can only be trapped on each uniform bearing point on the object. Steel cables, and then gather all the load-bearing points at one point and hang them on a hook claw. This kind of hooking method, the force is uneven. If the fixing method of the steel cables on the object is not handled properly, the phenomenon of falling objects will appear
