Measuring scale for quickly and precisely measuring high-speed rail overhead lines

Abstract

The invention belongs to the field of the measuring scale, and specifically discloses a measuring scale for quickly and precisely measuring high-speed rail overhead lines. The measuring scale comprises a scale body in a rigid straight scale structure, the scale body is orderly composed of four sections of measuring scales, and the four sections of measuring scales are connected as an integer through rotary bayonet locks; multiple fixed fixture blocks vertically bulged to the side of the scale body are orderly arranged at the scale body to an end tail part from an end socket part of the measuring scale body in an extension way; a measuring end is arranged at the scale body, length scales are arranged at a front face and a back face of the scale body measurement end, the total measurement length of the front face of the scale body measurement end is 1600mm, and the total measurement length of the back face of the scale body measurement end is 1630mm. The measuring scale for the high-speed rail overhead lines creatively adopts a four-fold structure, the scale body structure adopts the rigid steel scale to replace the flexible steel tape; the sizes of various parts are fixed and clamped on the rigid steel scale according to the distances of the parts, thereby once determining the sizes and distances of various parts on the high-speed rail overhead lines conveniently, effectively and precisely, and the mounting accuracy and the speed are improved.

Description

technical field [0001] The invention relates to a measuring ruler, in particular to a measuring ruler based on rapid and accurate measurement of high-speed rail catenary. Background technique [0002] High-speed railway catenary is a special form of power transmission circuit erected along the railway line to supply power to electric locomotives. It is composed of contact suspension, support device, positioning device, pillar and foundation. Contact suspensions include contact wires, suspension strings, catenary cables, and connecting parts. The contact suspension is erected on the pillar through the supporting device, and its function is to transmit the electric energy obtained from the traction substation to the electric locomotive. The supporting device is used to support the contact suspension and transfer its load to the pillar or other structures. [0003] It varies according to the section, station and large building of the catenary of the high-speed railway. Suppo...

Problems solved by technology

[0006] At present, in practical applications, steel tapes are mostly used for measurement. When steel tapes are used to determine the position of the locator, since the wrist arm assembly is a single-person project, and the steel tape is soft, it is most likely to cause the actual size to be biased. The inaccurate position of the locator also caused serious deviations in the positions of the hook positioning ring and the windproof cable ring on the positioning tube. One error resulted in three errors, resulting in continuous mistakes during the installation process.

At the same time, the measurement of the height of the wrist-arm structure in actual measurement or teaching tasks will inevitably lead to a relatively large size (the height of the wrist-arm structure is 1600mm). If the measuring ruler is also set to a corresponding length, it will be inconvenient to carry and store
