Abstract
The utility model discloses a kind of borer drill rod shaft coupling and main shaft connection structure, comprise shaft coupling and main shaft, described shaft coupling is connected with main shaft, on shaft coupling, there is the splicing sleeve extending along shaft coupling body to major axes orientation, on the inwall of splicing sleeve, be provided with internal spline, on main shaft, be provided with external splines with described internal spline relevant position, described external splines and internal spline engagement, the outer, end being connected with main shaft at splicing sleeve is provided with axial direction positioning device.The utility model novelty simple in structure, connects reliably convenient disassembly.
Description
Technical field
The utility model belongs to technical field of engineering machinery, especially relates to a kind of borer drill rod shaft coupling and main axle structure.
Background technology
Rig is as a kind of drilling engineering machinery, because of its high efficiency, in engineering construction field, be used widely, conventionally, rig need to pass to drilling rod by main shaft outputting power by shaft coupling, between traditional shaft coupling and main shaft, adopt and be threaded, although can guarantee that like this shaft coupling is connected with the reliable of main shaft, but, because be generally complicated disturbance operating mode during borer drill rod driving, easily make the connecting thread of shaft coupling and main shaft impaired, by rig, be generally open work simultaneously, rainwater, dirts etc. also easily cause screw thread pair corrosion, when needs carry out detachable maintaining, shaft coupling and main shaft easily clamp, the phenomenon that appearance cannot be extracted, affect efficiency of construction and rig application life.
Utility model content
For solving above technical problem, the utility model provides a kind of borer drill rod shaft coupling and main shaft connection structure of for convenience detach, novelty simple in structure.
Technical scheme is as follows:
A kind of borer drill rod shaft coupling and main shaft connection structure, comprise shaft coupling and main shaft, on described shaft coupling, there is the splicing sleeve extending to major axes orientation, main shaft stretches in described splicing sleeve, its main points are: on the inwall of splicing sleeve, be provided with internal spline, on main shaft, be provided with external splines with described internal spline relevant position, described external splines and internal spline engagement, the end overcoat being connected with main shaft at splicing sleeve has axial direction positioning device.Adopt above structure, can realize shaft coupling and be connected with the reliable of main shaft, meanwhile, main shaft and shaft coupling are by spline joint, and in the time of need to dismantling, main shaft can directly be extracted in shaft coupling splicing sleeve, convenient disassembly.
Further, described axial direction positioning device comprises main shaft adapter sleeve and positioning bolt, described main shaft adapter sleeve is split-type structural, by the left and right halfbody that is oppositely arranged on splicing sleeve both sides, surround and form, described left and right halfbody is locked by positioning bolt, described main shaft adapter sleeve bottom is clamped on splicing sleeve outer wall, and top is by main shaft claming.Adopt above structure, can realize the axial location that shaft coupling is connected with main shaft, while avoiding using, main shaft is deviate from from shaft coupling.
For guaranteeing the locating effect of main shaft adapter sleeve, preferably, described main shaft adapter sleeve has the first clamping part and the second clamping part extending internally, described the first clamping part is clamped on splicing sleeve outer wall, described the second clamping part is by main shaft claming, on splicing sleeve outer wall, be correspondingly provided with the first accommodation section, on main shaft, relevant position is provided with the second accommodation section.
Beneficial effect: adopt borer drill rod shaft coupling and the main shaft connection structure of above technical scheme, this novelty simple in structure, connects reliably convenient disassembly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of borer drill rod shaft coupling and main shaft connection structure, comprise shaft coupling 1 and main shaft 2, on described shaft coupling 1, there is the splicing sleeve 11 extending to major axes orientation, main shaft 2 stretches in described splicing sleeve 11, on the inwall of splicing sleeve 11, be provided with internal spline 12, on main shaft 2, be provided with external splines 21 with described internal spline 12 relevant positions, described external splines 21 and internal spline 12 engagements.
In conjunction with Fig. 1 and Fig. 2, can find out, the outer, end being connected with main shaft 2 at splicing sleeve 11 is relatively set with the main shaft adapter sleeve 3 of Split type structure, described main shaft adapter sleeve 3 is locked by bolt 4, described main shaft adapter sleeve 3 has the first clamping part 31 and the second clamping part 32 extending internally, described the first clamping part 31 is clamped on splicing sleeve 11 outer walls, described the second clamping part 32 clamps main shaft 2, correspondingly, the first accommodation section 13 is set on splicing sleeve 11 outer walls, the second accommodation section 22 is set on main shaft 2, the first clamping part 31 and the second clamping part 32 fall into respectively the first accommodation section 13 and the second accommodation section 22, when needs are dismantled, the bolt 4 of back-outing, open main shaft adapter sleeve 3, main shaft 2 can directly be extracted from shaft coupling.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
