Hand-push type positioning punching trolley for rock-soil drilling
The invention relates to the technical field of rock drilling, in particular to a hand-push type positioning punching trolley for rock-soil drilling. The hand-push type positioning punching trolley for rock-soil drilling comprises a supporting seat and a push-pull handle installed on the supporting seat, and further comprises a supporting shaft and a punching device; the punching device comprises a connecting sleeve, a pile column and a vibration assembly; the vibration assembly comprises a pressure spring and an inertia clamping piece; the inertia clamping piece comprises a trigger ring, an annular rail and two limiting assemblies; and each limiting assembly comprises a limiting groove, a telescopic block and a tension spring. According to the hand-push type positioning punching trolley for rock-soil drilling, before punching of the pile column, the pile column is made to be vertical when stopping swinging in a vibration mode, and the situation that the bearing capacity of the pile column is affected due to punching deflection is prevented.
本发明涉及岩石钻进技术领域，具体涉及一种用于岩土钻进的手推式定位打孔小车。一种用于岩土钻进的手推式定位打孔小车，包括支撑座和安装于支撑座的推拉把手，还包括支撑轴和打孔装置。打孔装置包括连接套、桩柱和震动组件。震动组件包括压簧和惯性卡接件。惯性卡接件包括触发环、环形轨和两个限位组件。每个限位组件包括限位槽、伸缩块和拉簧。本发明的一种用于岩土钻进的手推式定位打孔小车在桩柱打孔之前先通过震动的方式使得在桩柱停摆时较为竖直，防止因打孔偏斜而影响桩柱的承载能力。
