The invention discloses a folding leading beam device. The device comprises a cross beam, a rotary arm and a baffle, four groups of hoisting plates are arranged on the cross beam, the hoisting platesare connected with the cross beam through welding, and the cross beam is correspondingly connected with a linear bearing I, a linear bearing II and a special nut for a screw rod through bolts; the linear bearing I is connected with a guide shaft I in a sliding mode, the linear bearing II is in sliding connection with a guide shaft II, the special nut for the screw rod is rotationally connected with the screw rod, and the screw rod is rotationally connected with a mounted bearing; the baffle is correspondingly connected with the guide shaft I, the guide shaft II and the mounted bearing throughbolts; and the screw rod is fixedly connected with a handle through a key, the hoisting plates are rotationally connected with an oil-free bushing, and the oil-free bushing is fixedly connected with apin. The folding leading beam device is simple in structure, practical and convenient, capable of hoisting different positions through the four groups of hoisting plates and suitable for moving of aplurality of kinds of introduction wheels on the cross beam through adjustment of the distance between the baffle and a side plate of the cross beam.
Description
technical field [0001] The invention relates to the field of evaporators, in particular to a folding and introducing beam device. Background technique [0002] Tower cranes are referred to as tower cranes for short, also known as tower cranes, which originated in Western Europe. A rotating crane with the boom mounted on the top of a tall tower. The working space is large, and it is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, the boom and the base, etc. The working mechanism has four parts: lifting, luffing, slewing and walking. The electrical system includes motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc. [0003] The lead-in beam is an important part of the tower crane, which can play a guiding role. ...
