为了克服现有夹轨器结构复杂、控制不便的不足,介绍一种基于电液推进器驱动、连杆传动的夹轨器设计方案,阐述了其结构设计、工作原理和受力计算。该装置主要包括电力液压推进机构、弹簧复位机构和连杆夹持机构,由电液推进器提供夹钳打开动力,由可调式弹簧复位机构提供夹紧力,由连杆组实现运动传递,由电气控制实现夹紧机构的打开和安全锁死。该装置结构简单、制造成本低,能实现电气控制自动打开和快速加紧,安装与维修方便,安全性好,适合中小型轨道式起重设备。

In order to overcome the shortcomings of complex structure and inconvenient control of the existing track clamping device,a design scheme based on electro-hydraulic thruster drive and connecting rod drive is introduced,and its structure design,working principle and force calculation are described.The device mainly comprises an electric hydraulic propulsion mechanism,a spring reset mechanism and a connecting rod clamping mechanism.The clamp is provided by the electrohydraulic propeller,and the clamping force is provided by the adjustable spring reset mechanism.The movement is transmitted by the connecting rod group.The electrical control opens and locks the clamping mechanism securely.The device has the advantages of simple structure,low manufacturing cost,and can realize automatically opening and fast clamping,convenient installation and maintenance,good safety,which is suitable for small and medium-sized rail lifting equipment.
