Typer av vägspikar och installationstekniker
- Vilka är de vanliga typerna av järnvägspikar och vilka är deras egenskaper?
Spiral railroad spikes have threads and strong anchoring force after installation. They are suitable for concrete sleepers and can effectively fix rails. They are commonly used in trunk railways. Round-headed railroad spikes have a simple structure and a rounded head. The pressure on the rails is evenly distributed. They are suitable for wooden sleeper railways. They are easy to install but have relatively weak anchoring force. Square-headed railroad spikes have a square head, a large contact area with the sleeper, and a good fixing effect. They are often used in wooden sleeper lines on heavy-duty railways and can withstand large lateral forces. Elastic railroad Spikar har en viss elasticitet och kan buffra tågvibrationer . De är lämpliga för urban järnvägstransport och minskar påverkan på Sleepers .
- Vilka är de olika applikationsscenarierna för olika typer av järnvägspikar?
Spiral railroad spikes are suitable for railways with concrete sleepers because their thread design can be tightly combined with concrete to provide strong anchoring force, such as concrete sleeper tracks on high-speed railways and trunk railways. Round-headed railroad spikes are widely used in wooden sleeper railways. Wooden sleepers are soft in texture. Round-headed railroad spikes cause little damage to wooden sleepers during installation and are suitable for ordinary wooden sleeper lines. Square-headed spikes are more suitable for heavy-loaded wooden sleeper railways. The lateral force generated by heavy-loaded trains is large, and the large contact area of square-headed spikes can effectively resist the lateral force and prevent the spikes from loosening. Elastic Spikar används i urban järnvägstransit . urbana tåg startar och stoppar ofta . elastiska spikar kan buffra vibrationer, skydda svalare och minska buller .}
- Vilka förberedelser måste göras innan du installerar spikar?
Clean the nail holes on the sleepers, remove debris, dust and water in the holes, ensure that the nail holes are clean and dry, and ensure that the spikes and sleepers are tightly combined. Check the quality of the spikes, check whether there are cracks or deformations on the surface of the spikes, and whether the size meets the requirements. Unqualified spikes cannot be used. Prepare suitable installation tools, such as hammers, wrenches, etc., and select tools according to the type of spikes. Spiral spikes need to be tightened with a wrench, and round-headed spikes can be installed by hammering. Mark the installation position of the spikes, accurately mark on the sleepers according to Järnvägspositionen och mätkraven och se till att installationspositionen för spikarna är korrekt .
- Vilka är de viktigaste stegen i installationsprocessen för spikar?
Align the spikes with the spike holes according to the marked positions, and ensure that the spikes are perpendicular to the surface of the sleeper with a deviation of no more than 1℃to avoid uneven force on the spikes. Apply appropriate force during installation, tighten the spiral spikes with a wrench according to the specified torque, and tap the round-head spikes with a hammer to prevent them from being too loose or too tight. Check the installation height of the spikes. The height exposed from the surface of the sleeper must meet the regulations. Too high or too low will affect the fixing effect on the rails. After installation, check whether the spikes are stable. Shake the spikes by hand. If there är ingen uppenbar löshet, det är kvalificerat att se till att spikarna inte rör sig när tåget passerar .
- Vilken inverkan har kvaliteten på Spike -installationen på banan?
Firma installerade spikar kan effektivt fixa skenorna, upprätthålla stabiliteten i spårmätaren och säkerställa att den smidiga driften av tåget . löst installerade spikar kommer att få rälsen att flytta under den vibration av tåget, vilket resulterar i förändringar i banan och ökande körskiskar . crooked installation av tåget kommer att orsaka att orsaka orsakar, vilket kan orsaka att det kommer att orsaka att orsaka, lokalt. damage to the rails and spikes and shorten the service life. If the installation height of the spikes is inappropriate, if it is too high, the rails will be subjected to abnormal stress, and if it is too low, the fixing force will be insufficient, both of which will affect the overall stability of the track.
