Abstract
The utility model relates to a middling accelerator in the pit, in particular to a milling impactor which is used for improving milling efficiency. The middling impactor consists of an upper joint, a traveling impact block, a support spring, a fixed impact block and a lower joint, wherein the upper joint is in screwed connection with the lower joint, the upper joint is internally provided with the traveling impact block, the fixed impact block is in screwed connection with the lower joint, and the support spring is sheathed on the fixed impact block. After the milling impactor is used, the milling efficiency is improved, and the defect of low milling efficiency of the existing milling tool is overcome.
Description
Technical field:
The utility model relates to a kind of down-hole and quickens milling device, particularly a kind of milling impactor that improves milling efficient.
Background technology:
Existing commentaries on classics, mill, the technology of overlapping, mill just rely on suitable commentaries on classics to press, reasonably rotating speed carries out milling, and do not have a kind of acceleration milling tool of moulding, and milling efficient is low.
The utility model content:
The technical problems to be solved in the utility model provides a kind of milling impactor, and this milling impactor has been realized raising milling efficient.Overcome the inefficient deficiency of existing milling tool milling.
Technical solution adopted in the utility model is: a kind of milling impactor, by top connection, the impact block that moves about, support spring, fixedly top connection and lower contact screwed connection are formed in impact block and lower contact; The impact block that moves about is housed in the top connection, fixedly impact block and lower contact screwed connection, support spring is enclosed within fixedly on the impact block.
The beneficial effects of the utility model are: the utility model has been owing to adopted the impact block that moves about has been housed in the top connection, fixedly impact block and lower contact screwed connection, and support spring is enclosed within the structure on the fixing impact block, thereby has the function of raising milling efficient.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of milling impactor is by top connection 2, the impact block 4 that moves about, support spring 6, fixedly top connection 2 and lower contact 9 screwed connections are formed in impact block 7 and lower contact 9; The impact block 4 that moves about is housed in the top connection 2, and fixedly impact block 7 and lower contact 9 screwed connections, support spring 6 are enclosed within fixedly on the impact block 7.
With milling impactor top connection 2 and top drilling tool screwed connection, lower contact 9 and bottom milling tool screwed connection are lowered in the pit shaft to the precalculated position before the utility model construction.During construction, when liquid enters through top connection water channel 1, when process is moved about impact block water channel 3, because the resistance of liquid, the drive impact block 4 that moves about is descending, fixing impact block 7 is clashed into, when the impact block 4 that moves about comes downwards to when exposing bypass water channel 5, because separating liquid, impact block 4 resistances that move about reduce, under the effect of support spring 6, up return blocks bypass water channel 5 again behind the return, form new flow resistance again, the descending again bump of the impact block 4 that moves about is impact block 7 fixedly, and bump, return are realized impact effect so repeatedly.
