Problems solved by technology
The tail of the drilling tool is equipped with a live core cap, which is open, and the center of the live core cap is worn with a live mandrel with a pillow block, and a gasket is installed between the live core shaft and the live core cap. The live mandrel is completely immersed in the mud during operation, and the wear is intensified, resulting in inflexible rotation of the live mandrel, resulting in slow excavation speed, high energy consumption, low efficiency, and poor hole quality

Embodiment Construction
[0014] like figure 1 As shown, an impact drilling tool is mainly composed of a hollow cross-shaped drilling tool 1 in the middle, a movable core cap 3 at the tail of the drilling tool 1, a movable core shaft 5 with a pillow block 6 in the movable core cap 3, and a drilling tool 1 head. A flange 2 is welded on the upper periphery of the movable core cap 3, the flange 2 is fixed with bolts 18 and the tail of the drilling tool 1, and two bosses 4 are symmetrically welded on the inner wall of the movable core cap 3, Install an upper cover 7 and a bottom cover 14 on both ends of the movable core cap 3 respectively, make an oil injection hole 16 and an installation sealing ring 15 on the upper cover 7, plug it with bolts after oil filling, and make an oil drain hole on the bottom cover 14 8. Block with bolts, the upper end of the active mandrel 5 passes through the sealing ring 15 of the upper cover 7, and an anti-reverse ratchet 9 with a pair of symmetrical clips 17 is installed on...

The invention discloses an impact drilling tool for shaft sinking and drilling. The impact drilling tool mainly comprises a drilling tool, a movable core cap at the tail part of the drilling tool, a movable core shaft with a pillow block in the movable core cap, and an impact blade at the head of the drilling tool, and is structurally characterized in that: a flange plate is arranged on the periphery of the upper part of the movable core cap; two bosses are symmetrically arranged on the inner wall of the movable core cap; an upper cover and a bottom cover are arranged at the two ends of the movable core cap respectively; the upper cover is provided with an oil injection hole, a central round hole and a seal ring; the bottom cover is provided with an oil discharge hole; the upper end of the movable core shaft passes through the central round hole of the upper cover through the seal ring; the lower part of the pillow block of the movable core shaft is provided with an anti-inversion ratchet wheel with symmetric clips; the clips of the anti-inversion ratchet wheel are clamped on the two bosses on the inner wall of the movable core cap; and the impact blade at the head of the drillingtool is a single blade. The impact drilling tool has the advantages of high tunneling speed, high efficiency and good pore-forming quality.
Description
technical field [0001] The invention relates to a tool for well drilling and drilling, in particular to an impact drilling tool for well drilling and drilling. Background technique [0002] At present, there are mainly two ways of drilling wells and drilling holes. One is rotary drilling and the other is impact drilling. The structure of percussion drilling is mainly composed of drilling rig, wire rope and drilling tool. The way of tunneling is that the wire rope hangs the drilling tool. Driven by the drilling rig, it reciprocates up and down in the mud to impact the formation for drilling. The drilling tools used are mainly hollow drills and solid drills. The impact head of the drilling tool has a round head, a flat mouth and a cross. The impact edge is a double edge. The double edge is suitable for impact cutting, not suitable for rotary shoveling, nor for impact plus rotary drilling. A movable core cap is installed at the tail of the drilling tool. The movable core cap...
