Abstract
An earth rail is composed of an earth rail body, an earth rail bend and a connecting clamp plate. The earth rail body is of 'L'-shaped structure, the outer side of a vertical side of the earth rail body is a contact surface, and a horizontal side is an electric connecting side. The earth rail bend is composed of a straight section and a bent section. The inner end of the straight section is provided with a counterbore II and fixes an 'L'-shaped connecting plate, and the bottom edge of the 'L'-shaped connecting plate is provided with a bolt hole II. The connecting clamp plate fixedly connects the earth rail body and the earth rail bend via a countersunk bolt and the counterbore II. An electric connecting wire clamp is connected on the earth rail body via a bolt and a bolt hole I. The electric connecting wire clamp is connected between the earth rail body and the straight section of the earth rail bend via the bolt, the bolt hole I and the bolt II. The earth rail is good in matching with a locomotive body, and is convenient to mount and maintain.
