Abstract

The invention discloses an arched wrist arm of a tunnel and a measuring and determining method thereof. The problem that the arched wrist arm is not installed in place in a one-lane tunnel with smaller clearance is solved. The arched wrist arm comprises a wrist arm base (5), a silicon rubber insulator (7), an oblique edge (8) of the wrist arm and a horizontal edge (9) of the wrist arm, wherein a bearing cable base (10) is arranged on the horizontal edge (9) of the wrist arm; a bearing cable (13) is connected to the bearing cable base (10); the wrist arm base (5) is fixedly arranged on a movable plate (3); one end of the movable plate (3) is hinged together with a base body (2) through a hinge (4); an adjustable screw rod (6) is arranged between the movable plate (3) and the base body (2), and the openness between the movable plate (3) and the base body (2) is adjusted through adjusting the length of the adjustable screw rod (6). Moreover, the invention provides a specific measuring method. In the invention, the phenomenon of unreasonable relationship between pantograph and catenary is overcome, and the occurrence of the reworking during the installation of the arched wrist arm of the tunnel is avoided.

Description

technical field [0001] The present invention relates to a bow-shaped arm in a catenary for powering an electric locomotive, in particular to a bow-shaped arm of a power supply catenary used in a railway tunnel and a method for measuring and determining the bow-shaped arm according to the size determined by measurement. processing. Background technique [0002] In the construction process of electrified railway, the construction period of electrification construction is generally very tight. When installing the bow-shaped arm of the catenary, the rails on the subgrade have not been installed in place. The installation of the bow-shaped arm is measured under the condition of no rail. Finish. When installing an arched arm in a single-line tunnel with a small clearance, it is first necessary to measure the size of the pre-installed arched arm on site to determine the specific size of the arched arm, and then install the arm after processing the arm according to the size. In ac...
