Ground drill
The invention provides a ground drill. The ground drill comprises a supporting assembly, a drill rod assembly, a driving assembly and a brake assembly, wherein the drill rod assembly comprises a drillrod; the driving assembly is fixedly mounted on the supporting assembly and is used for driving the drill rod assembly to work; the brake assembly comprises a triggering element for directly or indirectly controlling the driving assembly to brake and a brake rod which is pivoted and mounted through a first pivot and is matched with the triggering element; and a projection part of the brake rod ona plane vertical to the axial direction of the drill rod is located outside a projection of the supporting assembly on the plane vertical to the axial direction of the drill rod. Compared with the prior art, the ground drill provided by the invention can passively trigger the brake assembly when a locked rotor is out of control, so that accidental injuries can be effectively prevented and the safety of an operator is enhanced.
本发明提供了一种地钻，包括：支撑组件；钻杆组件，所述钻杆组件包括钻杆；驱动组件，所述驱动组件固定安装在所述支撑组件上，用以驱动所述钻杆组件工作；以及刹车组件，所述刹车组件包括直接或间接控制所述驱动组件刹车的触发元件以及通过第一枢轴枢接安装并与所述触发元件相配合的刹车杆；所述刹车杆在垂直于所述钻杆轴向的平面上的投影部分位于所述支撑组件在垂直于所述钻杆轴向的平面上的投影之外。相较于现有技术，本发明地钻可以在堵转失控的时候，被动性地触发刹车组件，从而可以有效防止产生意外伤害，增强了操作者的安全。
