Abstract

The utility model relates to a double direction pulling and performing mechanism of double way shunting winch. The structure of the utility model is that the case type stander is internally provided with a big gear, the two sides of the big gear are symmetrically provided with rope wheels; the semicircle wire ropes of the two rope wheels at the same side of the big gear horizontally intertwine on the two rope wheels; the rope wheels are provided with a plurality of U shaped round sockets which are arranged in parallel; the axis gear is supported by two sets of axis gear bearings; the axis gear transfers torque to the big gear; the big gear is connected with a big axis through a key; the big axis is connected with the rope wheels through an expanding cover and transfers torque; the big axis bearing on the case type stander and the big axis form a double supporting structure. The utility model has the advantages of that the structure of the bearing rope wheel group on the two sides of the case is compact; the bearing capacity is big; the working performance is stable; the closing circulation of the rope wheel group in the case is safe and reliable. Adopting the patent technique of the utility model is beneficial for double direction shunting and the safe and normal circulation of the railway shunting manufacturing system.

Description

Bivector traction actuating unit in the two-way shunting winch

Technical field

The utility model relates to a kind of bivector traction actuating unit that is used on the two-way shunting winch, belong to endless rope traction winch equipment technical field.

Background technology

Traction actuating unit in the existing two-way shunting winch is rope sheave in reductor bilateral cantilevered layout structure, the power poor performance so system withstands shocks; Steel rope is wrapped on the cantilever rope sheave, and the rope sheave and the steel rope that expose sideway swivel outside equipment are the hidden danger of personal security accident and breakdown of equipment.

Summary of the invention

The purpose of this utility model is to propose a kind of later-model bivector traction actuating unit at the deficiency of prior art existence, adopts two groups of duplex types wheels and exposed gear bilateral symmetry combined box-type structure, and it is latent to personal security and breakdown of equipment effectively to solve equipment; Technical solution of the present utility model: its structure is to be provided with big gear wheel in cabinet rack, two sides in big gear wheel are arranged with rope sheave, utilize halfround steel wire rope wound in parallel on two rope sheaves of two rope sheaves of big gear wheel homonymy, many U type circular troughs are arranged on the rope sheave, their parallel arranged, shaft gear is by two quill gear bearings, the shaft gear transfer torque is given big gear wheel, big gear wheel and macro-axis pass through key joint, macro-axis and rope sheave connect and transfer torque by expansion set, and the big axle bearing on the cabinet rack, macro-axis bearing seat and macro-axis are formed dual-support structure.Advantage: casing bilateral bearings pulley set compact conformation, load-carrying capacity are big, stable work in work, pulley set are safe and reliable in the casing closed operation.Adopt the utility model patented technology, help two-way shunting, help railway shunting production system safety and normally move.
