Abstract
The utility model provides a rig unit head buffering damping device is driven on top, by driving rig unit head threaded connection's top connection, the lower clutch of being connected with the top connection with the top, the cover is established at the outside adapter sleeve constitution in the joint position of top connection and lower clutch, the utility model discloses the shock and vibration opposite vertex that can effectively eliminate the tup drives the influence that the rig produced, can audio -visual demonstration unit head falling speed, can also make that to unload the drilling rod soon more convenient.
Description
Technical field
The utility model relates to boring mechanic technical field, particularly relates to a kind of top drive drilling unit head damping device for pneumatic down-hole hammer drilling process.
Background technology
At present, the unit head on the market for the top drive drilling of pneumatic down-hole hammer drilling process is all be connected with downhole tool by direct-connected mode, and namely unit head is directly connected with downhole tool.Pneumatic down-hole hammer drilling construction technique carrys out fractured rock by the impact of the tup in downhole tool to rock, and therefore, in work progress, tup produces a large amount of vibrations, and this vibrations will be directly passed to unit head by drilling rod, and then pass to whole rig.This produces very bad impact by the part of the particularly unit head of the part on rig: bolt absent-mindedness, gear life reduce etc., easily security incident occur.Therefore be necessary to provide a kind of top drive drilling unit head damping device to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of top drive drilling unit head damping device, the impact that its impact shock effectively can eliminating tup produces top drive drilling, unit head decrease speed can be shown intuitively, can also make to revolve that to unload drilling rod convenient.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of top drive drilling unit head damping device, it is characterized in that: by the top connection be threaded with top drive drilling unit head, the lower contact be connected with top connection, be set in the adapter sleeve composition of the joint area outside of top connection and lower contact, described lower contact is connected with the drill rod thread of top drive drilling, the junction of described top connection and lower contact adopts the connected mode of grafting, one end of lower contact is inserted in one end of top connection, the insertion end outer circumference surface of top connection arranges sealing ring, the insertion end of top connection can move axially in lower contact, between described top connection and adapter sleeve, upper end cover is set, between described lower contact and adapter sleeve, bottom end cover is set, described lower contact can move axially in adapter sleeve.
Further, described top connection and upper end cover are welded to connect, and described upper end cover is connected with bolt between adapter sleeve; Spline joint is passed through between described lower contact and adapter sleeve; Described bottom end cover is connected with bolt between adapter sleeve.
Top drive drilling unit head damping device described in the utility model, adapter sleeve is increased between top drive drilling unit head and drilling rod, utilize lower contact moving axially in adapter sleeve to offset tup vibration to the impact of top drive drilling generation, substantially increase the application life of top drive drilling.Whether suitablely utilize the position of lower contact in adapter sleeve to move the decrease speed that can judge top drive drilling unit head, the operating efficiency of top drive drilling can be improved.The space utilizing top connection and lower contact to increase, for the shackle of drilling rod provides space, decreases the operation of mobile unit head, makes to revolve that to unload drilling rod easier.
Accompanying drawing explanation
Fig. 1 is the structural representation of top drive drilling unit head damping device described in the utility model.
Component names corresponding in figure is: 1 top connection, 2 lower contacts, 3 adapter sleeves, 4 sealing rings, 5 upper end covers, 6 bottom end covers.
Detailed description of the invention
Refer to shown in Fig. 1, the utility model provides a kind of top drive drilling unit head damping device, by the top connection 1 be threaded with top drive drilling unit head, the lower contact 2 be connected with top connection, the adapter sleeve 3 being set in the joint area outside of top connection and lower contact forms, described lower contact is connected with the drill rod thread of top drive drilling, the junction of described top connection and lower contact adopts the connected mode of grafting, one end of lower contact is inserted in one end of top connection, the insertion end outer circumference surface of top connection arranges sealing ring 4, the insertion end of top connection can move axially in lower contact, upper end cover 5 is set between described top connection and adapter sleeve, bottom end cover 6 is set between described lower contact and adapter sleeve, described lower contact can move axially in adapter sleeve.Described top connection and upper end cover are welded to connect, and described upper end cover is connected with bolt between adapter sleeve; Spline joint is passed through between described lower contact and adapter sleeve; Described bottom end cover is connected with bolt between adapter sleeve.
Based on the top drive drilling unit head damping device of said structure design, top connection 1 is integrally welded with upper end cover 5, upper end cover 5 is connected with adapter sleeve 3 by bolt, sealed by sealing ring 4 between upper and lower joint, when to make in whole passage no matter by mud or air, what capital was complete leads at the bottom of hole by pressure and flow, can not reveal; By spline joint between adapter sleeve and lower contact, there is between lower contact and adapter sleeve certain axial mobility; Bottom end cover is connected with adapter sleeve by bolt, plays positioning action to lower contact.During use, top connection is connected with top drive drilling unit head by connecting thread, and lower contact is connected with downhole tool by screw thread.
The above; it is only most preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; utilize the method content of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, all belong to the scope of claims protection.
