Description

Technical Field

[0001] The utility model relates to the technical field of column type tunnel bed inspection, in particular to a high-efficiency column type tunnel bed inspection device for preventing fastener contamination. Background Art

[0002] The column-type inspection tunnel bed is a maintenance area that must be configured for urban rail transit lines. The columns are mostly cast in situ. Rails are installed on the top of the columns and the rails are longitudinally spliced ​​to form vehicle tracks. A maintenance space is formed under the tracks to facilitate vehicle maintenance.

[0003] Announcement No. CN205329430U discloses a protective cover for rail fasteners. The protective cover structure is optimized to directly transfer the load to the track plate or track bed through adjusting plugs, bolts or threaded spikes to avoid damage to the protective cover and extrusion of the fasteners, ensuring that the protective cover has a feasible and reliable spatial positioning method during installation and can vibrate with the rails. At the same time, the protective cover is effectively prevented from contacting with air and water seepage, greatly reducing the possibility of rust on the metal parts of the fasteners. This protective cover can transfer loads and protect fasteners even if it is used on other track lines other than trams;

[0004] However, the above-mentioned protective device for rail fasteners still has the following problems in actual use: the protective cover corresponding to each fastener can achieve cover protection when subjected to extrusion stress and contamination, but when the entire track is subjected to stress, it will drive the fastener to be pressed down to the top of the sleeper, which requires the fastener to have a certain range of compression and rebound, and the protective cover covering the fastener is prone to breakage during the stress process, and it is also impossible to efficiently install a large number of fasteners;

[0005] Therefore, we propose a high-efficiency column-type tunnel bed inspection device that prevents fastener contamination in order to solve the above-mentioned problems. Utility Model Content
