Abstract
The utility model relates to the technical field of bearing equipment detection and particularly relates to a bearing stethoscope. A problem that an existing bearing auscultation method has a potential safety hazard and poor accuracy and does not meet the requirements of production is effectively solved. The bearing stethoscope comprises a tympanic membrane type medical auscultation device which comprises a stethoscope head (1), a rubber tube (2), earplugs (3), a connecting arm (4) and a telescopic rod (5), wherein a back side of the stethoscope head (1) is fixedly connected with the connecting arm (4), and a free end of the connecting arm (4) is hinged to one end of the telescopic rod (5). The stethoscope head is internally provided with a magnet. The bearing stethoscope has the advantages of portability, simple operation and practicality, the contraction of a connecting rod is free, and a safety coefficient and the work efficiency are greatly improved; at the same time, fault misjudgment in auscultation can be reduced, bearing hidden trouble is timely discovered and processed properly, a fault is eliminated in a sprouting state, and the equipment failure rate is decreased.
Description
Technical field
The utility model relates to bearing apparatus detection technique field, is specially a kind of bearing stethoscope.
Background technology
In numerous machinery and equipment of coal production, bearing often can break down, but at present the fault of bearing is judged the method that the Main Basis ear is listened; its way is to use wooden handle screw driver; withstand loading zone on the bearing cap with cutter head, ear is close to wooden handle and is carefully listened, but the shortcoming that exists is as follows:
When 1, selecting wooden handle screw driver to listen equipment bearing, because equipment must be in running status, therefore shorter screwdriver can bring very large potential safety hazard to the supervisory personnel, even careless manipulation causes the generation of personal injury.
2, all higher (generally about 3m) installed in more sealing-tape machine belt tensioning drum position of bearings, the maintainer just is difficult to use above-mentioned auscultation method in time to grasp the ruuning situation of bearing like this, once thoroughly bearing was dismantled to check its intact degree in 3 months but mostly adopt, so not only cause bearing to be in the unmanned blind area that checks in 3 months always, the probability that breaks down raises, the controllability that prevents fault reduces greatly, cause the kind of bearings accident to be difficult to accomplish that prevention and control are reliable, the blind area appears checking, laggard the robbing of fault generation repaiied often, buried very large safety in production hidden danger for normal production.And production task is day by day heavy, and the equipment bearing that regular dismounting is too much has also increased very large labor capacity virtually, can not adapt to the requirement of actual production,
When 3, using the wooden handle screw driver auscultation, ear is in non-air-tight state, and the high-decibel noise during large number quipments operation on every side directly has influence on the accuracy of auscultation, causes the mistake on the judged result.
Therefore, be necessary to invent a kind of convenient, fast and accurate bearing stethoscope, raise labour productivity.
Summary of the invention
There are above-mentioned problems in the utility model in order to solve existing bearing auscultation method, and a kind of bearing stethoscope is provided.
The utility model is to adopt following technical scheme to realize:
A kind of bearing stethoscope, comprise the medical auscultation apparatus of eardrum formula, the medical auscultation apparatus of described eardrum formula comprises auscultation head, proofed sleeve, earplug, also comprise linking arm and expansion link, the back side of described auscultation head (opposite face of eardrum) is fixedly connected with described linking arm, and an end of the free end of described linking arm and described expansion link is hinged.
During work, auscultation head, proofed sleeve, earplug, expansion link all detachably independently carry, and can select the different length proofed sleeve according to the distance distance; Because proofed sleeve is an airtight space, when auscultation head is positioned on the bearing, the film that the vibration of bearing causes on the auscultation head resonates, cause the closed gas in the stethoscope to shake thereupon, pass to an end of earplug, earplug adopts the stethoscope earplug, because the proofed sleeve cavity is narrow, obturation effect is good, and the amplitude of gas is just much bigger than front end, and the supervisory personnel hears that the sound that transmits is also just large a lot.Expansion link maintains easily personnel the bearing of diverse location height is carried out the sound auscultation, only needs expansion link to be elongated or shorten the bearing auscultation that can realize eminence or lower.The auscultation head rear adds the linking arm hinged with expansion link, and not only direction can arbitrarily be regulated, and convenient and expansion link is connected and fixed, and avoids that auscultation head drops in the auscultation process.
Based on said process, can carry out accurately differing heights scope inner bearing, diagnose easily and efficiently.
The utility model is reasonable in design, simple in structure, efficiently solves the problem that existing bearing auscultation method exists potential safety hazard, poor accuracy, is not suitable with the actual production requirement.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1-auscultation head, 2-proofed sleeve, 3-earplug, 4-linking arm, 5-expansion link.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of bearing stethoscope, comprise the medical auscultation apparatus of eardrum formula, the medical auscultation apparatus of described eardrum formula comprises auscultation head 1, proofed sleeve 2, earplug 3, also comprise linking arm 4 and expansion link 5, the back side of described auscultation head 1 is fixedly connected with described linking arm 4, and an end of the free end of described linking arm 4 and described expansion link 5 is hinged.Described auscultation head 1 is built-in with magnetite.
During implementation, install magnetite additional in the auscultation head 1, because the bearing case majority all is steel, iron material matter, when not affecting the acoustic effect, install a more small-sized magnetite additional at auscultation head film cavity wall, auscultation head only need be placed on the bearing cap of being listened when listening to bear vibration, can realize that automatic pick fixes, not only easy to operate, and the suction of magnetite can make auscultation head be fixed on firmly on the bearing cap, and also auscultation head to be placed on the clear sound of hearing on the bearing accurate than simple for the sound of so hearing.
The effect of expansion link 5 is the length by adjustable telescopic rod, can auscultation head be fixed or be positioned on the different bearing (ball) cover of high and low position easily, and play the effect of firm control auscultation head.
Linking arm 4 is hinged with expansion link 5, can control easily the direction of auscultation head 1, and handled easily uses.
Proofed sleeve 2 is stethoscopic main sound-conducting apparatus, and the sound during the auscultation head vibrophone is sent to earplug by airtight narrow proofed sleeve passage.
Bearing stethoscope described in the utility model mainly combines use and the transaudient principle of medical auscultation apparatus, utilize the eardrum formula vibrating device on the auscultation head 1, the narrow transaudient pipeline (proofed sleeve 2) of chamber wall by sealing, in conjunction with closed earplug 3, realize the minimal losses of sound in transmission, thereby reach under the environment that noise is larger around, still can hear clearly the sound that bearing transmits when rotating, thereby judge more accurately bearing real-time motion situation, for the bearing repair and maintenance provides comparatively favourable actual foundation.And, easy to carry, practicality simple to operate, expansion link 5 bars shrink freely, and have greatly improved safety coefficient and work efficiency; Fault erroneous judgement in the time of simultaneously can reducing auscultation is in time found bearing hidden danger, and is dealt carefully with, and fault is eliminated in bud, has reduced the generation of equipment failure rate.
