The invention provides large-scale road maintenance equipment for detecting looseness of a rail fastener. The equipment comprises a fastener looseness detection device and is characterized in that thefastener looseness detection device comprises a laser range finder, a vibration compensation device, a microcomputer control system, a video recognition system and a positioning synchronization system, the laser range finder is connected with the microcomputer control system, and the microcomputer control system is also connected with the video recognition system, the positioning synchronizationsystem and the vibration compensation device. Laser measurement is adopted, meanwhile, a vibration compensation system is arranged, the vibration compensation device measures vertical acceleration ofa detection beam through an inertia packet in the measurement beam, adverse factors such as gravity components and the like are removed, and secondary integration is carried out on the acceleration toobtain a displacement value. The vibration compensation device can compensate the influence of the vibration displacement of a train without being influenced by the vibration of the train, and a result is more accurate.
本发明提供一种用于检测轨道扣件松脱的大型养路设备,其包括扣件松脱检测装置,其特征在于:该扣件松脱检测装置包含激光测距仪、振动补偿装置、微机控制系统、视频识别系统、定位同步系统,激光测距仪连接所述微机控制系统,该微机控制系统还连接视频识别系统和定位同步系统和振动补偿装置。本发明采用激光测量,同时有振动补偿系统,振动补偿装置通过测量梁中的惯性包测量出检测梁的垂直加速度,除去重力分量等不利因素,对加速度进行二次积分可得位移值。振动补偿装置可以补偿列车自身振动位移的影响,不受列车振动的影响,结果更准确。
