Description

Pretensioning prestressed concrete track board assembly line curing system

Technical field

The utility model belongs to the production of track plates, particularly relates to the maintenance of pretensioning prestressed concrete track board assembly line System.

Background technology

In the production process of track plates for ballastless track of high-speed railway construction, need to carry out after the completion of concreting Steam curing and watering spray maintenance work process.Steam-cured main purpose is quickly to improve the intensity of track plates, contracting Short production cycle improves product quality and saves production cost.Track plates humiture is excessively high during preventing steam curing simultaneously There is the problem of drying shrinkage, crackle, warpage, maintenance processes increase the quality that spray moisturizing maintaining process improves product, are entire rails One of the key factor of quality in guidance tape construction technology.

CRTS type track plates are divided into I, II, III type of post stretching and the III type pre-tensioning system track plates with independent intellectual property right. Its mode of production is divided into the production of post stretching single mode and pre-tensioning system pedestal type produces two ways, but its steam-cured pattern basic one Cause, be all in the state that concrete prefabricated completions rear mold is as you were it is artificial be capped tarpaulin manually or steam curing shed formed it is closed Space is conserved, arrangement jet chimney is preset in canopy, and places Temperature Humidity Sensor manually and acquires humiture, passes through the temperature of acquisition Humidity controls the output of steam to reach the maintenance to track plates.It is then taking for single mode production model to spray moisturizing maintenance Pure manually to water, pre-tensioning system pedestal type takes timing, and manually the pattern of watering or manual stringing semiautomatic control carries out Wet curing.There is certain defect in the above-mentioned prior art：First, entire steam curing process is cumbersome using equipment, single-station More, user's number amount is more, and labor intensity is big；Second is that using fixed base or the steam-cured region of pattern of fixed monotype production It takes up a large area, pipe arrangement, workshop floor space is caused to greatly increase, increase and build a cost, and follow-up equipment is difficult to weight Multiple to use, soil is not easy second ploughing, causes greatly to waste；Third, steam-cured process implementing process is relatively complicated, many link people Work is manually operated, and artificial interference degrees are more, and the degree of automation is not high；Fourth, spray moisturizing cannot be carried out in time during steam-cured Maintenance, post-tensioning single mode production technology are required to raise tarpaulin and sprinkle water manually to water spray, while humiture in tarpaulin being caused to become again Change violent；Although being greatly improved in casting bed process, it is still artificial every time and hose is positioned over track plates table Face is manually withdrawn again after the completion, and the degree of automation is not high.Meanwhile no matter artificial or semi-automatic watering is and steaming and cultivating equipment phase Two processes of separation cannot carry out timely moisturizing according to the degree of water shortage of steam-cured track plate surface in the process in time, entire to steam Foster technique is still far from perfect；Fifth, during steam-cured, because the carry out flip tarpaulin for often needing to artificial is checked or sprayed water, mix Miscellaneous a large amount of human intervention factor, cannot strictly meet current specifications in real process《High-speed railway CRTSIII plate-types Non-fragment orbit pretensioning prestressed concrete track plates》(Q/CR567-2017) to the requirement of steam curing process Temperature and Humidity Control.

Go abroad in response to Chinese high ferro fast development, and the Belt and Road for carrying out now and《Made in China 2025》Composite strategies, adapt to the keen competition of current international high speed railway construction, research and develop more advanced, science elder generation It is imperative to open track plates intelligence pipeline system production technology.The steam-cured work produced as previous post-tensioning single mode or pedestal type Skill can not just adapt to the technological requirement of flowing water unit method.

The patent document that applicant is retrieved includes：

1, application No. is disclosing a kind of track plates steam curing system in 201410619250.3 application for a patent for invention, Its major technique solution be include maintenance canopy, pedestal, heating system, control system and aeration cooling system, maintenance canopy position Above pedestal, heating system includes jet chimney, boiler, solenoid valve and spray orifice, and steam pipeline laying is below pedestal, electromagnetism Valve and spray orifice are located on jet chimney, and solenoid valve is connected with spray orifice, and boiler is connected with jet chimney, and control system includes humiture Monitoring device, radio transmitting device and control device, humiture monitoring device are connected by radio transmitting device with control device, Aeration cooling system includes wind turbine and air hose, and air hose is laid on maintenance canopy ceiling, and wind turbine is connected with air hose.The above-mentioned prior art is deposited Main problem be that first, application environment is limited, the pedestal type mode of production can only be directed to, can not be general and meet existing rule Model requirement；Second is that pipe arrangement mode existing defects, because its steam-cured system is mold bottom fixed -piping, steam sprays upward, Closer with pipeline distance when being installed due to mold, during causing reality steam-cured, die bottom plate part humiture is excessively high, is not easy full It is more difficult for the requirement and adjustment that conserve humiture in sufficient specification；Third, Zigbee wireless communication modes are used, due to it Transmission mode is a reception multi-point transmitting, causes to acquire entanglement when sensor is excessive, while wireless module uses battery powered, It is unable to ensure the electricity usage degree of its battery, occurs many unnecessary drawbacks such as loss of data, entanglement under this operating mode；Four It is to be only capable of realizing steam curing, has a single function.

2, a kind of track plates steam curing constant temperature is disclosed in the utility model patent of Patent No. 201620856872.2 Water replanishing device, major technique solution be include water tank, the water tank be the automatic heating water tank of constant temperature, the water tank it is defeated Outlet is provided with water circulation system, and the water circulation system includes water cycle main pipeline and circulating pump, and the water recycles main pipeline On be provided with several laterals, the lateral is respectively placed in by each production pedestal, and the water tank passes through the cycle Pump watering cycle, above-mentioned of the existing technology main problem one be only realize track plates it is steam-cured during semi-automation Moisturizing operation, and the desired mode of production produces for pedestal type, can not achieve the operating type of pipeline system.Simultaneity factor can only The moisturizing maintenance for completing track plates, cannot well be combined with steam curing, to realize the Omnibearing automatic of steam-cured process Covering.
