Problems solved by technology

As an important part in the switch machine, the contact block realizes the switching function of the action and the display circuit, and feeds back the signal to the interlock system. However, due to the long-term friction between its own moving contact group and static contact group, there will be excessive switching resistance. In this case, after the turnout is switched in place, the blockage of the moving contact group cannot be switched and connected normally, which means that the circuit is faulty and the normal driving is delayed.

Abstract

The invention provides a contact seat for an electric switch machine. The contact seat comprises a contact seat base body, fixing plates used for assembling a static contact set and a support used forassembling a movable contact set. The support comprises a left support and a right support which are symmetrically connected to the contact seat base body through movable contact shafts respectively;a tension spring is arranged between the left support and the right support; fixing plates corresponding to the positions of the left support are arranged on the two sides of the left support respectively; fixing plates corresponding to the positions of the right support are respectively arranged on two sides of the right support; one end of the movable contact shaft is provided with an adjustingplate capable of rotating relative to the contact seat base body; and a tension spring is arranged between the right adjusting plate and the left adjusting plate. According to the contact seat for the electric switch machine, the tension spring between the left adjusting plate and the right adjusting plate and the tension spring between the left support and the right support form a double-tension-spring system, conversion power of the movable contact set is improved, and conversion stability of the movable contact set is improved.

Description

technical field [0001] The invention belongs to the technical field of railway switch switching equipment, in particular to a contact seat for an electric switch machine. Background technique [0002] The function of the electric switch machine is to switch and lock the switch rail / core rail, change the opening direction of the switch, and reflect the position status of the switch rail / core rail through the contacts. As an important part in the switch machine, the contact block realizes the switching function of the action and the display circuit, and feeds back the signal to the interlock system. However, due to the long-term friction between its own moving contact group and static contact group, there will be excessive switching resistance. In this case, after the turnout is switched in place, the blockage of the moving contact group cannot be switched and connected normally, indicating a circuit failure and delaying normal driving.
