Smart atomization water supplementing system suitable for CRTS 3 type pre-tensioned track board

Abstract

The invention discloses a smart atomization water supplementing system suitable for a CRTS 3 type pre-tensioned track board. The system comprises a master control cabinet, a control valve, an ultrasonic atomizer, an atomization controller, a heating water tank, a filter, a water inlet valve, a temperature sensor and a humidity sensor, wherein the master control cabinet is used for analyzing data obtained by measurement of the temperature sensor and the humidity sensor, and commanding the atomization controller; the atomization controller is used for further controlling the heating water tank and the control valve; a water inlet of the heating water tank is connected with a tap water pipe by the water inlet valve, and a water outlet of the heating water tank is connected with the control valve; the control valve is connected with one end of the filter by a water pipe, and the other end of the filter is connected with the ultrasonic atomizer; the ultrasonic atomizer is used for transforming water into water mist by means of vibration, and introducing the water mist into a pedestal of the track board through a mist guide pipeline. After the smart atomization water supplementing system is adopted, the maintenance time is effectively shortened; after the track board is supplemented with water, a track board body is good in strength stability; therefore, the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of water supply and maintenance systems for track slabs, and in particular relates to an intelligent atomization water supply system for CRTSⅢ type pretensioning track slabs. Background technique [0002] With the continuous development of my country's high-speed railway construction level, as the main track structure, ballastless track has been widely used in high-speed railway projects. At present, my country's high-speed railway ballastless track structure is mainly divided into two types: slab type and double block type. Among them, CRTSⅢ type slab ballastless track is a ballastless track structure type independently developed by my country with completely independent intellectual property rights. Representative products. The track slab steam curing system in the mass production process of track slabs is the core of track slab quality control. At present, in the construction process of CRTSⅢ type pretensioned trac...

AI Technical Summary

Problems solved by technology

The track slab steam curing system in the mass production process of track slabs is the core of track slab quality control. At present, in the construction process of CRTSⅢ type pretensioned track slabs, the water replenishment method in the steam curing stage of concrete mostly adopts traditional artificial watering or simple timing. The pipe spraying method is inefficient, and the proportion of manual work is high. The situation of uneven and untimely replenishment of water often occurs, and the amount of replenishment water depends on the length of time for manual switch valves, which makes the maintenance conditions of each batch of track slabs different.

Moreover, most of the traditional water replenishment methods use manual temperature control, and there is no mechanized water temperature control system.

In the process of water replenishment and maintenance, the temperature fluctuates greatly, resulting in an excessive temperature difference between the slab surface and the slab core, and uneven temperature stress in the track slab, which often causes quality problems such as poor appearance of the track slab and slow increase in concrete strength. Warping and deformation of the slab, the flatness of the rail bearing surface exceeds the standard, and even cracks, which is not conducive to the quality assurance of the track slab product
