Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of railway turnout installation, and in particular relates to a high-strength insulating T-iron. Background Art
[0002] During the installation of railway turnouts, the turnout installation device needs to be insulated from the rails to maintain the operation of the track circuit.
[0003] The existing T-irons generally have only one fixed iron core in the middle, and there are also pressure-mouth type T-irons. For the pressure-mouth type T-irons, the two connecting iron cores are used as a pressure mouth. Due to stress problems during use, the pressure mouth will deform and the distance between the two will become larger. Currently, a reinforcing rib is set between the two pressure mouths to enhance the stress strength of the pressure mouth. However, due to the small contact area between the reinforcing rib and the two pressure mouths, the stress strength of the T-iron is limited during actual use. Utility Model Content
