Description
Technical field
The utility model relates to coal mine gallery drilling field, and specifically one joins the rear-mounted all hydraulic drive rig power head of oil jacket.
Background technology
During the work of full-hydraulic power head drill oild chuck, oil jacket of joining based on floating-ring seal principle is generally used hydraulic oil oilhole on main shaft is delivered to chuck to realize the clamping of drilling rod and unclamp.Join oil jacket should and main shaft between have relatively high speed rotation, realize pressurize again and join oil, therefore processing and the matching requirements of joining oil jacket are higher, growth along with the working time, join oil jacket and engender following two situation: 1, join the abrasion of oil jacket inner sleeve and cause the gap between itself and main shaft to become larger, hydraulic system is revealed and is increased, and rig delivery efficiency reduces；2, join that gap between oil jacket and main shaft is too small or the two axiality difference causes joining oil jacket inner sleeve and main shaft bonding.Therefore, more change oil jacket and even change the unique channel being to recover rig revolution Clamping Circuit with main shaft in the lump.
The oil jacket of joining of all hydraulic drive rig power head of present stage is arranged in power head box, need when more changing oil jacket to pull down oild chuck, filter, fuel inlet fitting and other parts being associated with main shaft successively, pull down from main shaft again and join oil jacket, multiple person cooperational is needed to complete, workload is big, and destroy the original installment state of the internal each parts of drill power head, it is also possible to the damage of parts can be caused.
Therefore, solve to join oil jacket and change the problem wasted time and energy it is necessary to design a kind of novel all hydraulic drive rig power head structure, it is achieved join the quick-replaceable of oil jacket.
Utility model content
The purpose of this utility model is for deficiency of the prior art, one is provided to join the rear-mounted all hydraulic drive rig power head of oil jacket, to solve above-mentioned technical problem, its simple in construction, install that more to change oil jacket convenient and swift, and do not destroy the installment state of dispatching from the factory of unit head miscellaneous part.
For achieving the above object, the utility model discloses following technical scheme:
One joins the rear-mounted all hydraulic drive rig power head of oil jacket, including oild chuck, power head box, main shaft, join oil jacket body, main shaft end cap, bolt, rotating seal ring and bearing, described oild chuck is connected with power head box, described joining is provided with multiple rotating seal ring and bearing between oil jacket body and main shaft end cap, described oil jacket body, rotating seal ring and the bearing composition of joining rear-mounted joins oil jacket, described rear-mounted oil jacket of joining is connected with power head box, main shaft end cap is set in rear-end of spindle, is bolted to connection between described main shaft end cap and main shaft.
One disclosed in the utility model joins the rear-mounted all hydraulic drive rig power head of oil jacket, has the advantages that
1. joining oil jacket is rear-mounted structure, and hydraulic oil enters main shaft oilhole by joining the oilhole of oil jacket and main shaft end cap, is finally reached oild chuck, it is achieved the clamping of drilling rod and unclamping.When needing more to change oil jacket, it is only necessary to main shaft end cap is removed, can take out and join oil jacket, it is not necessary to successively oild chuck and unit head and interior section assembly all be pulled down, thus realize the purpose of quick change.
2. main shaft end cap is set in rear-end of spindle, the rotary motion of main shaft passes to main shaft end cap, main shaft end cap and join between oil jacket body generation relative rotary motion, when rotatory sealing was lost efficacy, have only to more change oil jacket or join oil jacket body and main shaft end cap, without changing main-spindle, decrease workload and saved maintenance cost simultaneously.
3. join oil jacket and be positioned at the outside of power head box, simplify the structure of power head box, improve the yield rate that casing manufactures, reduce production cost.
4. selecting rotating seal ring to prevent hydraulic oil from releasing, sealing property is reliable, changes convenient and swift.

Detailed description of the invention
Below in conjunction with embodiment and referring to the drawings the utility model is further described.
As shown in Figure 2, existing all hydraulic drive rig power head body structure, existing oil jacket body 13 of joining is positioned at the inside of all hydraulic drive rig power head casing 10, hydraulic oil enters in the oilhole joining oil jacket body 13 and main shaft 16 by filter 11 and fuel inlet fitting 12, it is eventually fed oild chuck 9, realize the clamping of drilling rod and unclamp, when joining oil jacket body 13 or joining oil jacket body 13 and main shaft 16 lost efficacy when needing to change simultaneously, first oild chuck 9 entirety must be pulled down, pull down right side main shaft end cap 15 the most successively, bearing 14, filter 11, the miscellaneous part that fuel inlet fitting 12 and main shaft left end are connected, could be by main shaft 16 with join oil jacket body 13 entirety and take out and be replaced.
Refer to Fig. 1.nullThe utility model one joins the rear-mounted all hydraulic drive rig power head of oil jacket，Including oild chuck 1、Power head box 2、Main shaft 3、Join oil jacket body 4、Main shaft end cap 5、Bolt 6、Rotating seal ring 7 and bearing 8，Described oild chuck 1 is connected with power head box 2，Described joining is provided with multiple rotating seal ring 7 and bearing 8 between oil jacket body 4 and main shaft end cap 5，When joining oil jacket body 4 and main shaft end cap 5 rotates against，Bearing 8 is used for bearing the radial load of main shaft 3，Rotating seal ring 7 can avoid hydraulic oil to release from both sides，The effectively pressure of protection oilhole mesohigh oil，In main shaft 3 rear end, main shaft end cap 5 is set，It is connected by bolt 6 is fixing between described main shaft end cap 5 and main shaft 3，Described join oil jacket body 4、Rotating seal ring 7 and bearing 8 form rear-mounted joins oil jacket，Described rear-mounted oil jacket of joining is connected with power head box 2，Rear-mounted join oil jacket and to be not arranged in power head box 2 internal，But at the rear side of power head box 2，When joining oil jacket body 4 and losing efficacy，As long as pulling down main shaft end cap 5 can be replaced.The utility model is relative to existing all hydraulic drive rig power head body structure, when needing more to change oil jacket, facilitates taking-up to join oil jacket, it is not necessary to oild chuck and unit head and interior section assembly is all pulled down successively, thus realizes the purpose of quick change.
The above is only preferred embodiment of the present utility model, is not intended to limit；Should be understood that, although the utility model being described in detail with reference to the various embodiments described above, it will be understood by those within the art that, the technical scheme described in the various embodiments described above still can be modified by it, or the most some or all of technical characteristic is carried out equivalent；And these amendments and replacement, do not make the essence of corresponding technical scheme depart from the scope of the utility model each embodiment technical scheme.
