The purpose of this utility model is to provide the pad that a kind of monitoring bolt loosens, and is capable of the self-monitoring of bolt looseness, and warns maintenance personal to reinforce, and for checking bolt looseness offer simple, directly perceived and the method for economy, improves overhaul efficiency.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
The pad that a kind of monitoring bolt loosens, including shim body, the side of described shim body is provided with fluting, it is provided with, in described fluting, the fixture block matching with it, described fluting is provided with through hole one, the position of described fixture block opposing through-bores one is provided with the through hole two consistent with through hole one aperture, run through described through hole one and through hole two is provided with the locking column matching, described locking column includes lower locking column and upper locking column, and the length of described lower locking column is identical with the thickness of fixture block, the length of described upper locking column is identical with the thickness of fluting, described shim body is equipped with fixing hole with the side of fixture block, the elastic wire being fixed in fixing hole by two ends between described shim body and fixture block is connected.
Further, described elastic wire is plugged by glue and is fixed in fixing hole.
Further, one end of described elastic wire and shim body being fixedly linked relative to the side of fluting, the other end is fixedly linked with the outside of fixture block.
The beneficial effects of the utility model: the warning of this pad is directly, in time, accident is avoided to occur, difficult point in monitoring is after bolt looseness rather than warns after coming off, this warning pad can be implemented in bolt looseness and warns maintainer at once, have an accident during can avoiding the time between overhauls(TBO), avoid missing inspection, improve overhaul efficiency；Economical and practical, without electronic monitoring mode, reduce cost to greatest extent.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of the utility model protection.
nullAs Figure 1-3，The pad that a kind of monitoring bolt according to embodiment of the present utility model loosens，Including shim body 1，The side of described shim body 1 is provided with fluting 2，It is provided with, in described fluting 2, the fixture block 3 matching with it，Described fluting 2 is provided with through hole 1，The position of described fixture block 3 opposing through-bores 1 is provided with the through hole two 5 consistent with through hole 1 aperture，Run through described through hole 1 and through hole 25 is provided with the locking column matching，Described locking column includes lower locking column 6 and upper locking column 7，And the length of described lower locking column 6 is identical with the thickness of fixture block 3，The length of described upper locking column 7 is identical with the thickness of fluting 2，Described shim body 1 is equipped with fixing hole 8 with the side of fixture block 3，It is connected by the elastic wire 9 that two ends are fixed in fixing hole 8 between described shim body 1 and fixture block 3.
In the present embodiment, described elastic wire 9 is plugged by glue and is fixed in fixing hole 8.
In the present embodiment, it is preferred that being fixedly linked relative to the side of fluting 2 in one end of described elastic wire 9 and shim body 1, the other end is fixedly linked with the outside of fixture block 3.
Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode, technique scheme of the present utility model is described in detail.
When pad not enabled, locking column is lock-out state, and lower locking column 6 and upper locking column 7 are dislocation.From Figure 2 it can be seen that lower locking column 6 is stuck between fluting 2 and fixture block 3, its half is embedded in fixture block 3, and half is embedded in fluting 2, all blocks fixture block 3 and fluting 2, makes fixture block 3 to eject.The half of upper locking column 7 is embedded in fixture block 3, and contacts with lower locking column 6 upper bottom surface, and the latter half of upper locking column 7 embeds in fixture block 3, and top half is in fixture block 3 outer lug.
When bolt is tightened, and pad enables, nut can be pressed downward against locking column 7(and see Fig. 3), upper locking column 7 just depresses locking column 6, makes the top half of lower locking column 6 extrude from fixture block 3, is completely in fluting 2, upper locking column 7 is completely in fixture block 3, and pad unlocks.
Principle of the present utility model: the utility model is made up of four parts, is shim body, fixture block, elastic wire and locking column respectively.When nut is tightened, when bolt is started normally to work by axial tension, bolts and nuts can give one pressure of pad, at this moment just has stiction between shim body and fixture block and between fixture block and nut and produces.When bolts and nuts are in normal operating conditions, very close to each other or gap is very little between shim body and fixture block and between fixture block and nut, the stiction of generation is equal to the elastic force that elastic wire gives fixture block, and balance between two forces, fixture block will not eject；Bolt once loosens, gap is produced between shim body and fixture block and between fixture block and nut, bolts and nuts reduce to the pressure of pad, stiction between shim body and fixture block also can reduce therewith, when stiction gives the elastic force of sub-pieces less than elastic wire, fixture block will eject, and the sub-pieces of ejection has the highlighted warning coloration of black Huang, and warning bolt has loosened.
In sum, by means of technique scheme of the present utility model, the warning of this pad is directly, in time, accident is avoided to occur, difficult point in monitoring is after bolt looseness rather than warns after coming off, and this warning pad can be implemented in bolt looseness and warns maintainer at once, has an accident during can avoiding the time between overhauls(TBO), avoid missing inspection, improve overhaul efficiency；Economical and practical, without electronic monitoring mode, reduce cost to greatest extent.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; any modification, equivalent substitution and improvement etc. that are all within spirit of the present utility model and principle, that made, should be included within protection domain of the present utility model.
