Abstract

The invention relates to a railway industry and electricity integrated electric switch device with a central locking polar integrated control unit. A high-strength anti-retreating moving lock mechanism, an integrated visible lock checking expression mechanism, a closed oil immersion overload unloading double speed transmission mechanism, a double speed, rapid stopping and high-efficiency permanent magnet direct-current motor and the like are integrated to form a compact non-squeezable central locking electric switch machine, wherein the high-strength anti-retreating moving lock mechanism is composed of a ball iron box seat / a heavy-duty bearing / an upper rack moving lock rod / a short and thick tooth crest lock; a lock checking rod / a direct-acting contact expression switch / a four-head lock checking block / a spiral starting disk / an axial quick-acting ring which are flatly placed and connected by body separation form the integrated visible lock checking expression mechanism; the closed oil immersion overload unloading double speed transmission mechanism integrates a 2K-H displacement and variable level differential transmission shaft with multiple tooth differences and short teeth, a stopping output wheel shaft with an eccentric bushing hammer; the compact central locking electric switch machine which can not be squeezed, a lengthened rail brace slide plate ( base rail / switch tie) central multi-lug insulation hinge, a crank and straight linked arm and a linked switch rail and point rail form an industry and electricity integrated squeezable and non-squeezable unit by means of a zero-clearance sleeved elasticity group pin and a double-port microgap hinge, low speed turnout unitization of single opening and single action, double slip separated action, hump double action and the like is achieved, a intermediate speed and high speed turnout switch rail and a point rail are synchronous in sections and combined with combination unitization to form the safe, reliable, advanced, adjustment-free, protection-free and industry and electricity assembled power-driven turnout of the whole transmission and whole spreading central locking electrode control device.

Description

technical field [0001] The electric switch equipment of the central lock pole control unit integrated with engineering and electricity is a new generation of electric switch equipment for railway turnouts. technical background [0002] The existing equipment has the following deficiencies: [0003] 1. The electric switch machine is installed on the external cantilever bracket, the system rigidity is low, the anti-interference ability is poor, the safety reliability is not high, the power is not strong, the assembly inspection and transportation cannot be carried out, and large-scale mechanized maintenance cannot be hindered; [0004] 2. Although the single-hook external lock method is partially strengthened, the double-safety and double-lock functions are weak, and there are crawling jams, tilting and jumping of the heart rail, multi-point asynchronous interference, sand, dust, ice and snow damage and other unsafe and unreliable factors. Fork squeeze alarm function; large a...

AI Technical Summary

Problems solved by technology

[0003] 1. The electric switch machine is installed on the external cantilever bracket, the system rigidity is low, the anti-interference ability is poor, the safety reliability is not high, the power is not strong, the assembly inspection and transportation cannot be carried out, and large-scale mechanized maintenance cannot be hindered;

[0004] 2. Although the single-hook external lock method is partially strengthened, the double-safety and double-lock functions are weak, and there are crawling jams, tilting and jumping of the heart rail, multi-point asynchronous interference, sand, dust, ice and snow damage and other unsafe and unreliable factors. Fork squeeze alarm function; large amount of maintenance, only used for high-speed roads, consumes residual synchronization technology, low efficiency; AC motor, small starting torque, power step-down, overload, easy to stall and burn, complex control and protection technology, electrical appliances , The amount of cable is large;

[0005] 3. Although the ZD6 type internal locking method has complete functions, the locking and squeezing functions of the switch machine are opposite to each other. The circular arc locking wears a lot and the efficiency is low; the load capacity of the planetary bearing of the reducer is insufficient, and the service life is low; the DC motor has a four-wire switch control circuit and the double excitation coil is seriously squeezed; Two hidden dangers of wire breakage: the linkage of the sharp rails, the curved and slender connecting rods, the low reliability of inspection and locking, and cannot be used for high-speed turnouts, the resistance to crushing is large, the squeezeability is poor, the range of crushing damage is large, and the alarm is not sensitive; The four point rails of the sub-turnout are linked, and the connecting rods are crossed and overlapped. There is a risk of loss of the point rails, and it is difficult to maintain the labor and electricity. The structure of the slow-moving electric switch machine cannot be used universally
