Embodiment Construction

[0034] Specific embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0035] The production and processing of hanging strings generally includes two steps, the first is wire feeding, and the specific process is as follows:

[0036] The electric control device (1) sends wire feeding signals and parameter information to other devices, and moves the left copper casing pushing device (3) to the left stop point of the left linear motion module (3-4) with a stroke of 300mm, and the length of the hanging string is controlled Both the device (5) and the right copper casing pushing device (4) are moved to their respective left dead centers, and the left copper casing clamping lever cylinder (3-1) and the right copper casing clamping lever cylinder (4-1) are started Hold the left copper sleeve (10) and the right copper sleeve (11) respectively; the purchased copper strands pass through the pay-off machine (2-1), the straightener ...

Abstract

The invention provides a catenary suspension string preplanning platform. The catenary suspension string preplanning platform mainly comprises an electric control device, an automatic wire sending and cutting device, a left copper sleeve pushing device, a right copper sleeve pushing device, a suspension string length control device, a hydraulic system, a suspension string tension presetting device and a reversing pressing ring device. The platform can intelligently control the procedures of automatically feeding the suspension string, penetrating a crimping pipe in a positive direction, encircling a heart-type ring, penetrating the crimping pipe in a negative direction, adjusting the tension of a stranded wire according to a preset value, determining the length of the stranded wire according to a preset value, automatically crimping a mechanical device, cutting off the wire according to the length requirement and the like, so that the manual intervention is reduced to the maximum extent. The catenary suspension string preplanning platform has the characteristics of high efficiency, high precision, high automation degree and the like as the traditional manual processing is replaced by mechanical intelligent production, can solve the problems such as poor precision, low efficiency and high reject rate existing in the current manual preplanning efficiently, can make up the blank of research in related fields at home and abroad, and can realize mechanical and professional construction of key procedures of the catenary construction.

Description

technical field [0001] The invention belongs to the technical field of catenary accessories preconfiguration, and in particular relates to a catenary hanging string preconfiguration platform. Background technique [0002] The current industry standard "Construction Quality Acceptance Standard for High-speed Railway Electric Traction Power Supply Engineering" (TB10758-2010) stipulates that "the allowable deviation of the prefabricated length of the suspension string is ±1.5mm". During the pre-assembly process of suspension strings, the product must be formed once and cannot be reused. The suspension string pre-configuration platform that was used before is basically manually measured the cutting length and crimping length of the suspension string. The degree of automation and pre-configuration accuracy is low, errors are prone to occur, and the scrap rate is high. [0003] In 2010, Yang Shuchang and others filed a patent application, the patent name is "Intelligent catenary ...
