Description
Technical field
The utility model relates to a kind of spanner, specifically, relates to a kind of duplex box spanner.
Background technology
Spanner in the middle of prior art is single sleeve, and mostly rely on manpower carrying out one by one to install or demounting bolt when in use, inefficiency, labour intensity is large.And all improper of spanner in the middle of prior art is applied to diesel engine of diesel locomotive, the particularly installation or removal of 280 diesel engine connecting-rod bolts, mainly because 280 diesel engine connecting-rod bolts do not have not at grade.
For above-mentioned technical problem, at present effective solution is not yet proposed.
Utility model content
For above-mentioned technical problem, the utility model proposes a kind of duplex box spanner, reduction labour intensity can be raised the efficiency, and easy to use.
The technical solution of the utility model is achieved in that
A kind of duplex box spanner, comprise sleeve one, sleeve two and location-plate, wherein, described sleeve one and described sleeve two are fixed on described location-plate respectively by bearing and adjusting nut, further, the end face end face that six sides outer with bolt match to the vertical range and described sleeve two of described location-plate lower surface that on described sleeve one, six sides outer from bolt match is different to the vertical range of described location-plate lower surface.
Further, described adjusting nut is provided with holding screw.
Further, the mid portion on described location-plate is fixed with gripper shoe, and the mid portion of this gripper shoe is fixed with hand handle.
Further, the other end of described hand handle is provided with shadoof, this shadoof be horizontally through hand and two ends all extend to the both sides of hand handle.
Further, the shape of described hand handle is cylindricality.
The beneficial effects of the utility model:
1) by arranging two sleeve, thus make the utility model can install or remove two bolts simultaneously, and then improve repair quality, promote efficiency, reduce labour intensity, and easy to use.
2) length of the part matched with outer six sides of bolt of the sleeve designed for working space, make the utility model be applicable to diesel engine of diesel locomotive, particularly the installation or removal of 280 diesel engine connecting-rod bolts, easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only a part of embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of duplex box spanner according to the utility model embodiment;
Fig. 2 is the using state schematic diagram of a kind of duplex box spanner according to the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in Figure 1-2, a kind of duplex box spanner according to the utility model embodiment, comprise sleeve 1, sleeve 22 and location-plate 1, wherein, described sleeve 1 and described sleeve 22 are fixed on described location-plate 1 respectively by bearing 9 and adjusting nut 3, further, the end face end face that six sides outer with bolt match to the vertical range and described sleeve 22 of described location-plate 1 lower surface that on described sleeve 1, six sides outer from bolt match is different to the vertical range of described location-plate 1 lower surface.Wherein, on location-plate 1, the centre-to-centre spacing control errors in installing sleeve 1 and two holes of sleeve 22 is at ± 0.026mm, and two holes and plane verticality control within 0.02mm.Two hole interference fit on bearing 9 outer ring and location-plate 1 load.Sleeve 22 and sleeve 1 external diameter load with bearing 9 inner ring interference fits respectively, ensure radial rotating.Adjusting nut 3 adjusts sleeve axial gap.Adjusting nut 3 is provided with holding screw 8.Holding screw 8 coordinates adjusting nut 3 use to play the effect that better axially adjustment is fastening.Mid portion on described location-plate 1 is fixed with gripper shoe 6, and the mid portion of this gripper shoe 6 is fixed with hand 4.Described hand is provided with shadoof 5 the other end of 4, and this shadoof 5 is horizontally through hand 4 and two ends all extend to hand the both sides of 4.The shape of described hand handle is cylindricality.Arranging hand, the utility model to be facilitated 4 and shadoof 5 portable with installation, and then more convenient when in use.
The utility model mainly designs for 280 diesel engine connecting-rod bolts, need to change spanner 22 with BSL230 hydraulic spanner dedicated pump 21 and two hollows when concrete use to cooperatively interact, pump is changed wrench 22 through oil pipe with two hollows and is connected, a hollow conversion wrench 22 is enclosed within the part matched with spanner of sleeve 22, and another hollow conversion wrench 22 is enclosed within the part matched with spanner of sleeve 1.The part matched with outer six sides of bolt of sleeve 22 is enclosed within the nut that needs to install or remove, being enclosed within the nut that needs to install or remove with the bolt part that six sides match outward of sleeve 1.When starting pump, pumping plant drives hollow conversion spanner 22 to rotate elasticity bolt.Table 23 on pump shows pretightning force.
Can install and remove two bolts by above-mentioned technical scheme the utility model, compact conformation, alleviates manual labor simultaneously, and is highly suitable in the installation and removal of 280 diesel engine connecting-rod bolts and uses.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
