Problems solved by technology

This method is complex to operate and has relatively high requirements on construction conditions, and it is necessary to lift the rail, remove the fasteners, ream the hole, clean up, and then repair the applied sleeper when repairing it. The repair of loose spikes requires a specific maintenance time. Repairs under normal circumstances will inevitably affect the operation of the railway line

Abstract

The invention discloses a sleeper structure capable of repairing spike looseness and a spike looseness repairing method.The sleeper structure is used for supporting a steel rail and comprises a buckling elastic strip, an elastic strip base, spikes and a sleeper, the buckling elastic strip is installed on the elastic strip base, and the steel rail is fixed to the elastic strip base through the buckling elastic strip; the spikes penetrate through the elastic strip seats and are inserted into threaded holes of the sleepers, so that the elastic strip seats are fixed on the sleepers; the device further comprises a threaded sleeve, and the threaded sleeve is arranged on the outer side of the spike in a sleeving mode. The repairing method for the loosened spikes comprises the following steps that the loosened spikes are screwed out of a sleeper; the thread bushing is fixed on the spike, and then the spike with the thread bushing is screwed into the sleeper; or the threaded sleeve is screwed into the sleeper, and then the spike is installed in the threaded sleeve.

Description

technical field [0001] The application relates to but not limited to the field of rail transit facilities, in particular to a sleeper structure capable of repairing loose spikes and a repair method for loose spikes. Background technique [0002] In the railway system, the sleeper is one of the important components for transmitting load and stabilizing the track. The technical level and quality of the sleeper directly affect the design and operation safety of the railway track. [0003] At present, the commonly used sleeper forms mainly include wooden sleepers, concrete sleepers and synthetic sleepers. Because concrete sleepers have many shortcomings such as heavy weight, fragility, and high rigidity, and wooden sleepers also have shortcomings such as corrosion, short life, and resource shortage, synthetic sleepers have been widely used. Synthetic sleepers are a general term for sleepers that are based on natural organic or synthetic polymer materials and reinforced with sho...
