Description

Tool for installing contact frame Technical Field The utility model relates to railway equipment, in particular to a tool for installing a contact frame. Background The contact frame of a switch machine is a key component in a railway switch control system that cooperates closely with the switch machine to ensure that a train can safely and accurately switch from one track to another. The main functions of the contact frame of the switch machine include (1) signal transmission, in which the contact frame contains a series of electrical contacts (or contacts) that are closed or opened depending on the position of the switch. In this way they provide information about the switch position to the railway signaling system. For example, one particular set of contacts may be closed when the switch is pointed to the straight track, and another set of contacts may be closed when the switch is pointed to the side track. (2) In addition to the electrical function, the contact frame also provides physical support for the moving parts inside the switch machine. It helps to stabilize and position the components, ensuring that they remain in the correct relative position during operation.
