Adjustable drill bit group for pile cutter and use method
The invention relates to the technical field of pile foundation machinery, in particular to an adjustable drill bit set for a pile cutter and a using method. Comprising a drill bit, a drill bit fixing block and a sleeve. The hydraulic cylinder is installed on the drill frame, and the drill bit set is connected with a piston rod of the hydraulic cylinder through a sleeve. One end of the sleeve is fixedly connected to the drill bit fixing block, and the drill bit set is connected with the hydraulic cylinder through the sleeve. The drill bit fixing block is provided with a groove-shaped sliding way, and the groove-shaped sliding way is provided with a limiting shoulder. The number of the drill bits is more than two, one end of each drill bit is provided with a sliding plate corresponding to the groove-shaped slide way, the sliding plates are placed in the groove-shaped slide grooves from the two sides, the drill bits can move along the groove-shaped slide ways to adjust the positions, and the drill bits are fixed through fasteners after the positions are determined; when the drill bit is replaced, the fastening piece is loosened and taken out from the two sides of the groove-shaped slide way. The structure has a limiting function, and ensures the uniformity of the pile breaking depth, so that the pile breaking quality is ensured, the net breaking rate is improved, and steel bars are not damaged in the pile breaking process.
本发明涉及桩基机械技术领域，具体为一种用于截桩器的可调式钎头组及使用方法。包括钎头、钎头固定块与套筒。液压缸安装于钎架之上，钎头组通过套筒与液压缸活塞杆相连。所述套筒一端固接在钎头固定块上，钎头组通过套筒与液压缸相连；所述钎头固定块设有槽型滑道，槽型滑道设有限位台肩；所述钎头为两个以上，钎头一端设有与槽型滑道相应的滑板，滑板从两侧放入槽型滑槽内，钎头能沿槽型滑道移动调整位置，位置确定后通过紧定件固定；钎头更换时，松开紧定件，从槽型滑道两侧取出。该结构具有限位功能，确保了破桩深度的均匀性，从而保证了破桩质量，提高了破净率，确保破桩中不伤及钢筋。
