Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to an adjustable double-block ballastless track structure. Background Technique

[0002] A railway is a track line for trains and other means of transportation. It uses locomotives to tow vehicles to form a train (or vehicles with their own power devices) to run along a regular route. This is a land transportation method. The train runs on two parallel railway tracks. The railway tracks provide an extremely smooth and hard medium for the train wheels, enabling the train wheels to roll with the least friction, improving the riding comfort and saving energy. If configured properly, railway transportation can save five to seven-tenths of the energy compared to road transportation when carrying the same weight of goods. A railway consists of multiple basic structures and components, including railway tracks, ballast beds, electrification facilities, signal systems, stations and platforms, as well as bridges and tunnels, etc. The railway tracks are the tracks for the train to run, usually composed of steel rails, laid on the ground or on structures such as viaducts and tunnels. The ballast bed is the basic structure of the railway laid on the ground, bearing the weight of the railway tracks and the train. The electrification facilities provide power for the train, and the signal system ensures the safety and smooth operation of the train. From the perspective of railway grades, railways are roughly divided into several types such as high-speed railways, intercity railways, passenger and freight co-line railways, and heavy-haul railways. High-speed railways are designed with a relatively high speed and mainly serve passenger transport; intercity railways mainly serve the fast and convenient passenger transport between adjacent cities or urban agglomerations; passenger and freight co-line railways serve both passenger trains and freight trains; heavy-haul railways mainly meet the large-capacity freight demand.

[0003] A double-block ballastless track with the patent number CN219653408U published on the Chinese Patent Network includes a ballast bed plate unit, a fastener system, and steel rails; the ballast bed plate unit includes multiple double-block sleepers and a cast-in-place integral ballast bed plate; the double-block sleeper includes two concrete sleeper blocks and three hollow steel pipes, and the concrete sleeper blocks and the hollow steel pipes are cast into an integral body; the three hollow steel pipes include two long hollow steel pipes and one short hollow steel pipe. The long hollow steel pipes are in the lower layer, and the short hollow steel pipe is in the upper layer. The central connection lines of the cross-sections of the long hollow steel pipes and the short hollow steel pipe are arranged in a triangle in the cross-section of the concrete sleeper block. This double-block ballastless track can greatly reduce the secondary permanent load of the track, improve the transportation and construction convenience of the double-block sleepers, improve the construction accuracy, and ensure the project quality. However, this ballastless track does not have an adjustment component and cannot adjust the fixed position according to the use needs when supporting and fixing the railway tracks, so its versatility is poor and it is difficult to meet the use needs of users.

[0004] Therefore, it is necessary to design and transform the double-block ballastless track to effectively prevent the phenomenon that it is difficult to adjust. Content of the Utility Model
