AI Technical Summary
Technical Problem
The existing guide frame causes serious dust generation when the drill rod is working during tunnel pipe roof construction, and manual cleaning of the debris is required after the drill rod is withdrawn from the borehole, which affects work efficiency.
Method used
Design a positioning guide frame that includes a guide sleeve, dust suppression components, and cleaning components. The frame automatically sprays water mist to reduce dust by triggering the components and automatically cleans up the slag when the drill rod is withdrawn, thereby improving efficiency.
Benefits of technology
It effectively reduces dust during drill pipe operation, automatically cleans up slag and soil on the drill pipe, and improves the efficiency of tunnel construction.

Abstract
本发明公开了一种便于隧道管棚施工的定位导向架，包括：定位架、导向套筒、分别设置在导向套筒中的降尘部件与清理部件、触发部件；导向套筒设置在定位架上；清理部件可分离的与钻杆连接；触发部件包括设置在导向套筒内的调节块、分别与调节块连接的第一触发组件与第二触发组件；降尘部件和清理部件均与调节块连接；第一触发组件的一端可分离的钻杆连接；第二触发组件的一端可分离的与钻机连接。本发明，导向套筒用以引导钻杆工作，钻杆伸入导向套筒与第一触发组件接触，使降尘部件对钻孔处喷洒水雾；完成钻孔后，钻机与第二触发组件接触，清理组件与钻杆接触并对其表面上的土渣进行清理，无需工作人员对钻杆进行清理，提高钻孔效率。
