Description

Technical Field

[0001] The utility model relates to the technical field of synthetic sleeper drilling equipment, in particular to a synthetic sleeper rapid drilling machine. Background Art

[0002] Polyurethane synthetic sleepers are a new type of sleepers with the advantages of light weight, excellent physical and mechanical properties, good anti-pullout performance of track gauge spikes, and abundant synthetic material resources. They have great potential to replace traditional wooden sleepers and concrete sleepers.

[0003] During the manufacturing process of composite sleepers, it is necessary to punch rail fastener holes and guard rail fastener holes on the upper surface to facilitate fixing the composite sleepers and fasteners during installation. Currently, handheld drilling tools or radial drilling machines are generally used for drilling. These two operation methods require each hole to be positioned and then drilled separately. Manual positioning will have certain deviations and take a long time, which can easily lead to low drilling efficiency and affect the drilling position accuracy. Since the fastener holes determine the installation position of the rails, if the fastener holes have too large deviations, it will also affect the final driving safety. Utility Model Content
