Abstract

The invention relates to the technical field of hoisting devices, in particular to a cantilever crane special for metallurgy. A rotary motor is arranged in an inner cavity of a rotary drive portion fixedly connected with the top end of a stand column, one side face of a rotating base in sleeved connection with the power output end of the rotary motor is fixedly connected with one end face of a cantilever, and an inner cavity of the cantilever is in sliding sleeved connection with a telescopic beam in the axial direction. An electric block is fixedly connected to the outer end of the telescopicbeam. The power output end of a telescopic motor arranged in the rotating base is connected with a threaded rod, and the threaded rod is in threaded sleeved connection to the axis of the telescopic beam. A connecting seat is in sliding clamped connection in a groove formed in the lower surface of the cantilever in the axial direction, the upper surface of the connecting seat is fixedly connectedto the lower surface of the inner end of the telescopic beam, and the connecting seat is rotationally connected with a supporting rod. A locating bolt is in sleeved connection in a through hole of a connecting lug seat of one outer side face of a circular ring in sliding sleeved connection with the periphery of the stand column in the vertical direction. The bottom end of the supporting rod is rotationally connected to the periphery of the locating bolt in a sleeving manner. The problem that the length of a cantilever of an existing cantilever crane cannot be adjusted is solved.

Description

technical field

[0001] The invention relates to the technical field of lifting devices, in particular to a special cantilever crane for metallurgy. Background technique

[0002] Cantilever cranes are industrial components and are light-duty working-strength cranes. The cantilever crane is generally composed of a column, a cantilever and an electric hoist; the bottom of the column is usually fixedly connected to the base, and the electric hoist runs in a straight line from left to right on the cantilever to lift heavy objects. Cantilever cranes generally have the advantages of light weight, large span, large lifting capacity, flexible use, economy and durability, so they are widely used in industrial production processes. In the metallurgical industry, the cantilever crane is also a commonly used equipment.

[0003] However, the length of the cantilever arm of the existing cantilever crane is not adjustable, which limits the scope of use of the cantilever crane and cannot m...
