Description

The impact type unit head

Technical field

The utility model relates to a kind of impact type unit head, belongs to the drilling rig power plant technical field.

Background technology

The fast pore-creating rig is the special equipment of Drilling shot hole during dig under the field condition.During fast pore-creating rig work in the past, unit head is not with impact function, can only lean on the down-the-hole hammer earlier broken at the bottom of the hole in the bad ground; And through forming dust and particle after the grinding of drill bit, blow out with compressed air, form the cavity bigger than drilling rod; The drill bit that impacts then drives drilling rod to be continued forward, once more at the bottom of the contact hole, and impact grinding once more; So back and forth, reach the purpose of drilling depth pore-forming.Drilling efficiency is low, and the pore-forming ratio is little, has satisfied not the purpose of fast pore-creating under the field condition.

The utility model content

The technical problem that the utility model will solve is to overcome when existing unit head is holed not have impact function, and the defective that drilling efficiency is low provides a kind of vibratory impulse formula unit head, and its pore-forming efficiency is high.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

The impact type unit head comprises casing and out splice going splice, and power output shaft is connected with out splice going splice through gear assembly, and out splice going splice also is connected with hydraulic impactor.

The connected mode of said gear assembly and clutch end and out splice going splice is; Clutch end is connected with splined shaft right-hand member endoporus through flat key; Splined shaft is provided with the pinion that connects through spline, gear wheel and pinion, and the gear wheel left part is connected with out splice going splice.

Said gear wheel right part is connected with end cap, and end cap is connected with the hydraulic impactor output.

The utility model device can be accomplished impact type boring, can accomplish Different Strata boring demand, has improved operating efficiency greatly, and is safe and reliable.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

As shown in Figure 1, the impact type unit head comprises casing and out splice going splice, and power output shaft is connected with out splice going splice through gear assembly, and out splice going splice also is connected with hydraulic impactor.The connected mode of gear assembly and clutch end and out splice going splice is; Clutch end is connected with splined shaft right-hand member endoporus through flat key; Splined shaft is provided with the pinion that connects through spline, gear wheel and pinion, and the gear wheel left part is connected with out splice going splice.The gear wheel right part is connected with end cap, and end cap is connected with the hydraulic impactor output.

Particularly, pinion 6 is housed on the splined shaft 7, both tighten together through the spline of itself, axially lean on the step of splined shaft 7 to position, and splined shaft 7 right-hand member endoporus are fastened on hydraulic motor 12 output axle heads through flat key 11; Splined shaft 7 right-hand member cylindrical places lean on pair of bearings to press fit over the end cap that oil sealing 10 is housed 9, and oil sealing 10 just in time compresses splined shaft 7 and casing 8 gap between the two, prevents that gear oil from spilling.Casing 8 is tightened on hexagon socket head cap screw 2 and packing ring 3 with 9 of end caps; The left end of splined shaft 7 axially leans on spacer ring 5 location, leans on pair of bearings 4 to compress splined shaft 7 and casing 8 then, is tightened on end cap 9 usefulness hexagon socket head cap screws 2 with packing ring 1 then.

Splined shaft 7, pinion 6 by hydraulic motor 12 driven rotary the time, bearing inner race rotates together, the outer ring then is fixed on the casing inner hole wall, does not rotate.Gear wheel 18 is meshed with pinion 6, and an end of gear wheel 18 is clamped on the end cap 19 by bearing 17 and oil sealing 20, and gear wheel 18 ends and six sides cover 21 usefulness screws 33 and packing ring are tightened on together; The other end of gear wheel 18 is clamped on the end cap 16 by bearing 17; Hydraulic impactor 13 is clamped on the end cap 16 by end cap 14, is radially fixed by two reversal connection bolts 34.Out splice going splice 25 right-hand members put 22 4 of butterfly springs, and support ring 23 is clamped in the six sides cover 21, and fix with back-up ring, and the outside is clamped on guard shield 24 between gear wheel 18 and the end cap 19 again, a boss location of outer circle.The smooth cylindrical place of out splice going splice 25 mid portions puts 22 2 of butterfly springs, support ring 23 outer cover top boards 27, leans on back-up ring 32 fixing, and the cylindrical step place of pressing plate 27 just tightens with guard shield 24 ends.The other end endoporus place of pressing plate 27 roll sleeve 26 and sell 31 the assembling enter, the end is stuck in the groove of end cap 29 with dust ring 28, sealing ring 30, is contained in end cap 29 on the pressing plate 27 again.

Unit head through one-level gear-box speed change, produces required working speed and moment of torsion by OMP160 type fluid motor-driven.Through oil circuit control, can change with the stratum and in time regulate output speed and moment of torsion.BH201 type hydraulic impactor is installed on the unit head, and the high-frequency percussion merit that hydraulic impactor produces directly passes to drilling tool through the unit head output shaft.The output shaft of unit head directly is connected with drilling tool, through changing the flow direction of hydraulic motor turnover oil, has changed turning to of output shaft, is convenient to motor-driven unloading drill rod thread.Unit head is fixed on the supporting plate of advance frame haulage gear, in case of necessity can be with its removed.

What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
