Description

Representing connection mechanism and turnout switching equipment Technical Field The invention relates to the technical field of railway turnout switching equipment, in particular to a representation connecting mechanism and turnout switching equipment. Background The switch switching device is used for switching and locking the switch and monitoring and checking the position of the switch, and when a train passes through, the switch switching device must ensure that the movable part of the switch is fixed at the position of the open straight strand or the side strand. The switch switching equipment comprises a switch machine, a switch outer locking device, a mounting device and the like. The switch machine is an actuating mechanism of switch switching equipment, is driving safety equipment for switching switches, and can realize switch switching, locking and supervision functions. The mounting means are means for supporting and fixing the switch machine and the connecting bars. The connecting rod is an important part of the installation device, and two ends of the connecting rod are respectively connected with a detection rod and a switch rail of the switch machine and are used for transmitting the switch rail displacement (displacement perpendicular to the length direction of a stock rail) to the switch machine, so that the switch machine correctly feeds back the switch position, and the switch machine realizes the supervision and inspection of the switch position. The main function of the switch tongue is to ‌ guide the wheels of the train to smoothly and safely turn from one track to the other track ‌, thereby realizing the switching of the running direction of the train. Because of the large day and night temperature difference, the switch blade climbs back and forth (i.e., moves back and forth). The existing traditional design shows that connecting rod is relatively poor to switch rail adaptability of crawling, when the switch rail appears great climbing, can lead to showing the position of connecting rod and change, and then cause the inside detection rod breach information of switch machine to be unusual or the card to hinder the trouble for the switch machine can't normally work. The point rail creeping back and forth refers to a displacement phenomenon of the point rail relative to a stock rail or other fixed parts in the line direction under the action of the longitudinal force of the train running. The displacement is a common defect of railway turnout, and is mainly characterized in that the switch rail moves forwards or backwards under the influence of factors such as temperature change, frequent passing of a train, loosening of a fastener and the like. The point rail generally climbs forward when the air temperature increases, and generally climbs backward when the air temperature decreases. ‌ wherein the tip of the point rail (i.e., the point of bifurcation of the switch) is displaced ‌ in the forward direction ‌ of bifurcation (i.e., the direction of approach of the train to the switch) relative to its designed position. ‌ backwardly crawl ‌ the tip of the point rail is displaced in the aft direction ‌ of the switch (i.e., the direction in which the train leaves the switch, enters the side line or straight strand) relative to its design position ‌. Therefore, there is an urgent need to develop a technology that can solve the above technical problems.
