A long-line cable force control system and method used in a cable-rail structure

Abstract

A long-term cable force control system and method suitable for empty rail systems, including three parts: a temperature sensor, a controller device, and a hydraulic jack system; the hydraulic jack system includes a jack system and a motor, and the motor is used to drive the jack system The expansion and contraction of the jack cylinder in the middle, the motor is controlled by the controller device; the arrangement is as follows: the jack system is arranged and fixed at the support in the middle of the main track, and the two ends of the jack cylinder and the two ends of the longitudinally extended main cable are stressed. The connection can realize the simultaneous elongation or shortening of the cable body on both sides, which not only solves the anchorage of the main cable, but also solves the unfavorable force of the support; the temperature sensor should be arranged in a place not directly exposed to the sun, and should be arranged It can also be arranged in the middle of multiple spans to obtain the average temperature of the cable body; the temperature sensor is preset in the main cable. The invention has clear objectives, is convenient to implement, and has great significance for the driving stability, safety and comfort of the empty rail structure.

Description

technical field [0001] This application relates to the field of aerial orbits, and specifically applies to related technologies of aerial orbits. Background technique [0002] The invention patent of the cable rail air track is an innovative transportation system. Its main safety is controlled by the lower supporting cable body, and its performance is guaranteed by the cable force to achieve the required structural line and adapt to the upper load. The sensitivity of cable force change to load effect is especially obvious when the structure is light and under moving load. The above was disclosed by Chinese inventor Li Fangyuan on 2011-01-05, CN101935978A.

[0003] Since the cable-rail aerial track system adopts a hollow structure and is mostly composed of metal components or materials, it is significantly affected by direct sunlight and temperature in a purely open-air environment. Considering the high thermal expansion coefficient of metal materials, it will lead to In the lower case, the elongation of the cable reduces the cable force, which directly leads to the deformation of the cable body and causes its structural line to not conform to the original design range, and this problem is more obvious for long-line cables.

At the same time, for the sake of structural safety, usability and economy, the cable body is extended through the connection mode in the aerial track to adapt to the self-adaptability of the cable body stress, which will also cause the cable body to slip to the long-span section under the influence of high temperature
