Switching device for drilling and grouting integrated construction equipment
The invention discloses a switching device for drilling and grouting integrated construction equipment, and belongs to the field of drilling and grouting equipment. The front end of an outer pipe of the switching device is connected with a drill bit, the rear end is connected with a drill rod, and a plurality of first grouting holes are formed in the side wall close to the front end. The driven rotating body is a cylinder with the front end closed and the rear end open, a second grouting hole is formed in the side wall, a plurality of first outflow holes are formed in the front end face, the driven rotating body is arranged in the outer pipe, and the front end face is close to the front end of the outer pipe. Second outflow holes corresponding to the first outflow holes in number and position are formed in the cover plate, and the cover plate is clamped and fixed in the outer pipe and located in front of the driven rotating body; the rotating structure is configured to drive the outer pipe and the driven rotating body to rotate relatively, so that the first grouting holes and the second grouting holes in the corresponding positions are aligned or the first outflow holes and the second outflow holes in the corresponding positions are aligned. The drilling state and the grouting state can be switched in time according to working requirements, and flushing fluid and grouting fluid can be switched and injected in time and injected into different positions.
本申请公开了一种用于钻注一体化施工设备的切换装置，属于钻孔注浆设备领域。切换装置的外管的前端连接钻头，后端连接钻杆，靠近前端的侧壁上设置有多个第一注浆孔；从动旋转体为前端封闭，后端开口的柱体，侧壁上设置有第二注浆孔，前端面上设置有多个第一出流孔，设置于外管内且前端面靠近外管的前端；盖板设置有与第一出流孔数量和位置相对应的第二出流孔，卡固于外管内，并位于从动旋转体的前方；旋转结构被配置为带动外管与从动旋转体相对旋转，以使对应位置处的第一、二注浆孔对齐或者对应位置处的第一、二出流孔对齐。本申请能够实现钻进状态和注浆状态根据工作需求及时切换，也能够满足冲洗液和注浆液及时切换注入并且注入不同的位置。
