Abstract
The utility model belongs to the technical field of repairing and assembling of a roller-bit hole rig and particularly relates to a mounting guide device for a framework sealing ring of a hollow shaft in the roller-bit hole rig as well as a use method of the device. The mounting guide device comprises a cone shaft and a force applying spanner connected with the cone shaft in an insertion way, wherein an outer cone thread column is arranged in the middle of the large-diameter end face of the cone shaft; a thin-wall insertion sleeve is arranged on the outer circumferential edge of the large-diameter end face of the cone shaft; the outer cone thread column is in threaded connection with a cone thread hole formed in the end face of the hollow shaft; the inner surface of the thin-wall insertion sleeve is connected with the outer surface of the hollow shaft in a clearance fit manner; a through hole connected with the force applying spanner in an insertion way is formed in the small-diameter end of the cone shaft; and the force applying spanner is a cylindrical pin shaft. The mounting guide device can solve the problem of difficult mounting, poor precision or the like in the original framework sealing ring, is easy to operate and convenient to control, adjust and correct, guarantees the mounting precision, effectively reduces the mounting intensity, saves labor resources and improves the mounting efficiency.
Description
Technical field
The utility model belongs to the technical field of rotary drill maintenance assembling, especially relates to a kind of rotary drill quill shaft backbone sealing ring installation and guide device.
Background technology
The swinging pressing mechanism of rotary drill mainly is made up of rotary gear box and quill shaft, and quill shaft runs through the rotary gear box middle part, and quill shaft is a vitals of carrying high-pressure blast and water; On quill shaft, two backbone sealing rings are installed with the reduction box matching part; Be used for the bearing on the sealed hollow axle, prevent that quill shaft from intaking when rotary work in reduction box, the installation quality of backbone sealing ring directly influences the effect of sealing; If the reduction box water inlet will cause rotary drill to be shut down.Because gross weight is heavier during the backbone sealing ring integral installation; And backbone sealing ring and quill shaft are tight fits; The inner ring of backbone sealing ring is relatively littler than quill shaft external diameter, causes difficult installation, in case the improper not only sealing of installation measure can not guarantee; And be easy to damage the sealing inner ring, cause sealing function to lose efficacy.
Summary of the invention
The utility model provides a kind of rotary drill quill shaft backbone sealing ring installation and guide device; Guarantee when backbone sealing ring is installed to neutrality and installation accuracy, avoid because the drainage that tilts to cause is installed, and imitate and reduce installation strength; Practice thrift human resources, improve installation effectiveness.
The purpose of the utility model realizes through following technical proposals:
The rotary drill quill shaft backbone sealing ring installation and guide device of the utility model; It is characterized in that by the axis of cone and therewith the application of force spanner that plugs of the axis of cone form; The middle part of described axis of cone bigger diameter end face is provided with the outer cone thread post, the circumferential periphery place is provided with the thin-walled sleeve; Described outer cone thread post is threaded with the taper thread hole that the quill shaft end face is provided with; Described thin-walled sleeve inner surface is connected with quill shaft outer surface matched in clearance, and described axis of cone miner diameter end is provided with the through hole that plugs with described application of force spanner.
Described application of force spanner is a cylindrical pin.
The wall thickness of described thin-walled sleeve is 2.5 ㎜-3.5 ㎜.
The advantage of the utility model: the utility model has been owing to adopted above-mentioned guider, solved the problems such as difficult installation or low precision of original backbone sealing ring effectively; Backbone sealing ring is good to neutrality, and steadily is in place, and has effectively improved the situation that backbone sealing ring often damages in installation process, practices thrift because of installing and damages the raw material loss that causes.The utility model is operated easily, is convenient to control adjustment centering, guarantees installation accuracy; Effectively reduce installation strength, practice thrift human resources, improve installation effectiveness.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The rotary drill quill shaft backbone sealing ring installation and guide device of the utility model; It is characterized in that by the axis of cone 1 and therewith 6 of application of force spanners plugging of the axis of cone 1 form; The middle part of the described axis of cone 1 bigger diameter end face is provided with outer cone thread post 4, the circumferential periphery place is provided with thin-walled sleeve 5; Form annular recess; Described outer cone thread post 4 is threaded with the taper thread hole that quill shaft 2 end faces are provided with, and described thin-walled sleeve 5 inner surfaces are connected with quill shaft 2 outer surface matched in clearance, and the described axis of cone 1 miner diameter end is provided with the through hole that plugs with described application of force spanner.This rotary drill quill shaft backbone sealing ring installation and guide device has solved problems such as difficult installation or the low precision of original backbone sealing ring effectively.
Described application of force spanner 6 is a cylindrical pin.
The wall thickness of described thin-walled sleeve is 2.5 ㎜-3.5 ㎜.
The method for using of rotary drill quill shaft backbone sealing ring installation and guide device; At first application of force spanner 6 is inserted in the guider miner diameter end through hole; Through rotation application of force spanner 6 quill shaft 2 of the axis of cone 1 with rotary drill linked together; Outer cone thread post 4 rotations of the bigger diameter end face of guider are mounted in the quill shaft threaded one end hole, make external screw thread and the quill shaft 2 end face compression fit of outer cone thread post 4 of the bigger diameter end face of guider, get into to quill shaft 2 edges in the annular recess of guider formation; Make backbone sealing ring good to neutrality; And steadily be in place, effectively improved the situation that backbone sealing ring often damages in installation process, practice thrift because of installing and damage the raw material loss that causes; Then, take off guider miner diameter end application of force spanner 6, again backbone sealing ring 3 is imported to bigger diameter end gradually from the miner diameter end of the axis of cone 1, until arriving the installation site.
The utility model is operated easily, is convenient to control adjustment centering, guarantees installation accuracy; Effectively reduce installation strength, practice thrift human resources, improve installation effectiveness.
