Description

Technical Field

[0001] The utility model belongs to the technical field of railway track installation, in particular to an automatic disassembly device for Pandrol fasteners. Background Art

[0002] Pandrol fasteners are parts used to connect rails and sleepers on the track. Their function is to fix the rails on the sleepers, maintain the track gauge and prevent the longitudinal and lateral movement of the rails relative to the sleepers. Through the reliable connection between the rails and sleepers, they can give full play to their buffering and shock absorbing performance under dynamic action, delaying the accumulation of residual deformation of the track.

[0003] However, due to the hardness and shape of the rails themselves, as well as the clamping pressure of the Pandrol fasteners, the installation and removal of the Pandrol fasteners by construction workers using manual tools is a great test of their physical fitness. When manpower consumption is too high, construction efficiency is reduced and it is even difficult to ensure work quality.

[0004] Chinese patent publication number: CN109355985A, discloses a method for automatic disassembly of rail fasteners, including the following steps: the device is placed on the rail through the running wheels and driven by the power mechanism, the fastener detection mechanism realizes longitudinal rough positioning, the transverse positioning mechanism realizes transverse positioning, the longitudinal fine positioning detection module realizes longitudinal fine positioning, and the magnetic wrench loosens the fastener and adsorbs it to the material receiving mechanism. The invention also provides a rail fastener automatic disassembly device, including a chassis assembly, a fastener detection mechanism, a transverse positioning mechanism, an operating mechanism, a power mechanism, a parking brake mechanism, a material receiving mechanism, a hydraulic system, and an electrical control module. The power mechanism drives the device to travel, the fastener detection mechanism realizes longitudinal rough positioning, the transverse positioning mechanism realizes transverse positioning, the operating mechanism is used for longitudinal fine positioning and loosening the fastener and adsorbing it to the material receiving mechanism, and the electrical control module controls the operation of each component.

[0005] This patent replaces the use of internal combustion motor wrenches for manual work, solving the problems of insufficient labor, heavy workload, and high time consumption, but there is still room for improvement in improving the efficiency of fastener disassembly and assembly.
