The invention belongs to the technical field of transport vehicles, and particularly relates to a gooseneck hydraulic steering device and a transport vehicle, the gooseneck hydraulic steering device comprises a gooseneck frame, a swing mechanism, a hydraulic cylinder A and a hydraulic cylinder B. The swing mechanism is eccentrically provided with a pin shaft and is hinged with a connecting rod through the pin shaft, and the rear end of the connecting rod is hinged with a swing arm; the middle of the swing arm is hinged to a fixing base in the middle of the gooseneck frame, and the two ends of the swing arm are hinged to the hydraulic cylinder A and the hydraulic cylinder B respectively. The problem that the overall height of the gooseneck is difficult to control due to the structural layout of a hydraulic oil cylinder is solved, a transport vehicle can better adapt to the height limiting requirement of road transportation, the trafficability of the transport vehicle under the complex road condition is improved, the size of loadable goods is further increased, and the transportation cost is reduced. The transportation efficiency and flexibility of the transportation vehicle are guaranteed, meanwhile, the steering sensitivity is improved, the steering accuracy is guaranteed, and the transportation vehicle is more stable and safer in the running process.

    本发明属于运输车辆的技术领域,具体涉及一种鹅颈液压转向装置及运输车,包括鹅颈架、回转机构、液压缸A和液压缸B,所述回转机构上偏心设置有销轴并通过销轴铰接有连杆,所述连杆的后端铰接有摆动臂,所述摆动臂的中部铰接于鹅颈架中部的固定座上且其两端分别与液压缸A和液压缸B铰接设置。本发明解决因液压油缸的结构布局而使鹅颈的整体高度难以控制的问题,使运输车辆能够更好地适应道路运输的限高要求,提高了运输车辆在复杂道路条件下的通过性,进一步增加了可装载货物的尺寸,保证了运输车辆的运输效率和灵活性,同时提高了转向的灵敏度,确保了转向的准确性,使得运输车辆在行驶过程中更加稳定和安全。
