The invention provides a tower crane variable-amplitude trolley walking wheel anti-disengaging device, and belongs to the technical field of variable-amplitude trolley anti-disengaging, the tower crane variable-amplitude trolley walking wheel anti-disengaging device comprises a variable-amplitude trolley frame, a variable-amplitude trolley walking wheel, a wheel bearing, a pin shaft and a protective end cover, the wheel bearing is arranged in the variable-amplitude trolley walking wheel, and the protective end cover is arranged on one side of the variable-amplitude trolley walking wheel; one end of the pin shaft penetrates through the variable-amplitude trolley walking wheel and is fixed to the variable-amplitude trolley frame, and one end of the protective end cover is arranged between the wheel bearing and a shaft cap boss of the pin shaft. One end of the protection end cover is arranged between the wheel bearing and the shaft cap boss of the pin shaft, the contact area of the protection end cover and the wheel bearing face is large, and when the wheel bearing is damaged and deformed, the protection end cover can effectively abut against the wheel bearing and prevent the wheel bearing from being extruded out; the variable-amplitude trolley walking wheel and the pin shaft are still in an integral connection state, the purpose of preventing the variable-amplitude trolley walking wheel from falling off is achieved, the structure is compact and simple, disassembly and assembly are easy and convenient, stress is reasonable and efficient, and safety and reliability are achieved.

    本发明提供一种塔机变幅小车行走轮防脱装置,属于变幅小车防脱技术领域,包括变幅小车车架、变幅小车行走轮、车轮轴承、销轴和防护端盖,车轮轴承设置在变幅小车行走轮的内部,防护端盖设置在变幅小车行走轮的一侧,销轴的一端穿过变幅小车行走轮并固定在变幅小车车架上,且防护端盖的一端设置在车轮轴承与销轴的轴帽凸台之间。本发明的防护端盖的一端设置在车轮轴承与销轴的轴帽凸台之间,防护端盖与车轮轴承面的接触面积较大,发生车轮轴承损坏变形时,防护端盖可以有效顶紧车轮轴承并阻止车轮轴承挤出,保证变幅小车行走轮与销轴仍处于一个整体连接状态,达到变幅小车行走轮防脱的目的,结构紧凑简洁,拆装简单方便,受力合理高效,安全可靠。
