The invention discloses a small-diameter tunnel inverted arch concrete transportation trolley capable of rapidly switching tracks. The trolley comprises a frame, a wheel set, a gear motor, a storage battery pack and a control box, wherein four pairs of wheel sets are mounted at the bottom of the frame; the two pairs of wide-gauge wheel sets are in contact with the inverted arch transportation track and can move on the inverted arch transportation track; the two pairs of narrow-gauge wheel sets are in contact with a tunnel transportation track and can move on the tunnel transportation track; when the transportation trolley travels in a small-diameter tunnel, the transportation trolley travels to an inverted arch formwork area through the tunnel transportation track by means of the two pairsof narrow-gauge wheel sets, then the transportation trolley is switched to the inverted arch transportation track integrated with an inverted arch formwork by means of the two pairs of wide-gauge wheel sets, and concrete is transported to a pouring point to be poured. The tunnel inverted arch concrete transportation trolley can directly run from one set of tracks to another set of tracks with different track gauges, rapid track switching is achieved, the concrete pouring efficiency is improved, concrete pumping construction is avoided, and the pipe blocking risk is reduced.

    本发明公开了一种可快速切换轨道的小直径隧道仰拱混凝土运输小车,包括车架、车轮组、减速电机、蓄电池组和控制盒,车架的底部安装有四对车轮组,两对宽轨距车轮组与仰拱运输轨道相接触,可以在仰拱运输轨道上移动,两对窄轨距车轮组与隧道运输轨道相接触,可以在隧道运输轨道上移动,运输小车在小直径隧道中行走时,首先借助两对窄轨距车轮组通过隧道运输轨道行驶至仰拱模板区域,然后借助两对宽轨距车轮组切换至仰拱模板集成的仰拱运输轨道上,将混凝土运输至浇筑点浇筑。本发明可实现隧道仰拱混凝土运输小车由一组轨道直接行驶至另外一组不同轨距的轨道,实现快速切换轨道,提高混凝土浇筑效率,避免混凝土泵送施工,降低堵管风险。
