The invention belongs to the technical field of aircraft traction equipment, and particularly relates to a wheel holding mechanism arranged in the middle of a tractor body, the wheel holding mechanism comprises a platform, and the platform is provided with a front wheel pressing assembly; the front wheel pressing assembly comprises a hinge seat, the hinge seat is provided with a first rotating shaft, the first rotating shaft is provided with a first pressing plate, the hinge seat is provided with a first oil box, the first oil box is provided with a first fan-shaped cavity, the first rotating shaft extends into the oil box to be connected with a first sealing push plate, the platform is provided with an oil storage chamber, the oil storage chamber is provided with an oil pipe, and the oil pipe is provided with a U-shaped pipe and a pressing valve. The upper side of the front nose wheel of the airplane is limited through the first pressing plate, the accident that the front nose wheel of the airplane jumps up and down easily in the traction process and jumps out of the wheel holding mechanism to get rid of a rodless airplane tractor is avoided, the safety and stability of the wheel holding mechanism are greatly enhanced, and the use risk is reduced.

    本发明属于飞机牵引设备技术领域,具体涉及牵引车本体中部设有抱轮机构,抱轮机构包括平台,平台设有前轮压紧组件;前轮压紧组件包括铰接座,铰接座设有第一转轴,第一转轴设有第一压板,铰接座设有第一油盒,第一油盒设有第一扇形腔,第一转轴伸入油盒内连接有第一密封推板,平台设有储油室,储油室设有油管,油管设有U形管,油管设有按压阀;通过第一压板在飞机前鼻轮上侧增加限制,避免了牵引过程中飞机前鼻轮容易上下跳动,飞机前鼻轮跳出抱轮机构而摆脱无杆飞机牵引车的事故发生,大大增强抱轮机构的安全稳定性,减少使用风险。
