Summary of the invention
The present invention is for above-mentioned the deficiencies in the prior art, it is provided that a kind of multiple spot abrasionproof pressure hanging device.
The multiple spot abrasionproof pressure hanging device of the present invention, it is by top connection, centralizer and drill bit are constituted, the two ends of described centralizer connect top connection and drill bit respectively, centralizer is the hollow cylinder of both ends open, the outer wall of centralizer is provided with helical groove, the inside of centralizer is provided with fluid oscillating block, rotate wheel seat and block ring, fluid oscillating block is on the fin of centralizer inwall, rotate wheel seat seat in the top of fluid oscillating block, the inwall of rotation wheel seat is radially fixed thankss for your hospitality circulation wheel, block ring is connected in the top rotating wheel seat, the top of block ring is provided with back-up ring, back-up ring is connected in the inwall of centralizer.
As a further improvement on the present invention, the inwall of described block ring is funnel-form.
As a further improvement on the present invention, described fluid oscillating block internal diameter is that staged reduces along the fluid direction of motion.
As a further improvement on the present invention, the outer wall of described centralizer is provided with wear-resistant strip I.
As a further improvement on the present invention, the outer wall of described top connection is provided with elevator groove.
As a further improvement on the present invention, the afterbody of described top connection is provided with wear-resistant strip II.
The multiple spot abrasionproof pressure hanging device of the present invention, the centralizer indoor design of its uniqueness, the shock-effect of hydraulic energy can be converted to act on the periodic shock active force of drill bit, drill bit is made also to have shock-effect while rotating, landwaste is forced to overturn, improve the degree of purification in shaft bottom, reduce the rock Repeated Cutting caused due to chip hold down effect, simultaneously because the inertia of drilling fluid causes it to form a low-pressure area in the bottom of drill bit to shaft bottom, thus significantly improve the stress of rock near drill bit and shaft bottom, it is effectively improved drilling efficiency；The top of drill bit connects centralizer, it is to avoid the accident such as tiltedly, the connection top connection of centralizer top occur to beat during adopting brill, facilitates it to be connected with drill collar, and all has wear-resistant material at the outer wall of top connection and centralizer, extends the service life of whole device.
