Abstract
The invention discloses an abnormal sound detection device for a gear case. The detection device comprises a detection unit arranged on a gear case body and a control unit arranged movably. The detection unit fixed at the inner wall of the case body by bolts consists of an audio detector, a bluetooth device, and a rechargeable battery arranged inside the detection unit, wherein the audio detector and the bluetooth device are inlaid in the surface of the detection unit. The control unit includes a PLC and a storage device and is in bluetooth wireless connection with the detection unit. According to the invention, the audio detector detects an abnormal sound of a gear wheel due to a fault in the gear case and transmits a signal to the control unit; and a user uses the control unit to check correlated information and determine location of the gear case with the fault, so that the fault can be dealt with timely. Because of the way of fault location positioning by the control unit, the trouble of checking one by one is eliminated; a fault can be found at the early stage; the maintenance of the gear case can be carried out conveniently; and the application range is wide.
Description
Technical field
The present invention relates to a kind of mechanical component failures detection device, be specially a kind of gear-box abnormal sound detection device, belong to flight-line maintenance detection technique field.
Background technology
Gear-box is an important mechanical part in drive mechanism, and internal control mechanism is accurate, and narrow space there will be fault unavoidably, affects the work efficiency of plant equipment after long-play.Plant equipment often judges by experience after going wrong, or check one by one with subjective inference and finally determine the position come into question, sometimes can not promptly and accurately judge the fault that where occurs, and relatively time-consuming, it it is only sometimes minor issue, wherein gear-box is because producing abnormal sound in operation process after lacking lubricating oil or gear wear, if this kind of minor issue can quickly be found and position, can be greatly enhanced maintenance efficiency undoubtedly.
Summary of the invention
It is an object of the invention to provide a kind of quick location gearbox fault, a kind of gear-box abnormal sound easy to use detection device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of gear-box abnormal sound detects device, including the detection device being arranged on gear case body and the movable control device placed, described detection device is bolted on described cabinet wall, detection device includes being embedded in the detection audio frequency detector of apparatus surface, blue-tooth device and being arranged on detection rechargeable battery within device, described control device includes PLC and memorizer, controls device with described detection device by Bluetooth technology wireless telecommunications.
Preferably, it is additionally provided with comparator inside described control device.
Preferably, described control apparatus surface is provided with LED display.
Compared with prior art, the invention has the beneficial effects as follows: the abnormal sound sent because of fault by audio frequency detector detection inner gear of the gear box, and this signal is transmitted to controlling device, by controlling device, user checks that relevant information determines the gear-box position broken down, it is thus possible to process in time, Bluetooth technology is used to make audio frequency detector break away from wired restriction such that it is able to be conveniently placed in each gear-box, guilty culprit site just can be positioned by controlling device, and eliminate the trouble checked one by one, it can find fault in early days, facilitate the maintenance of gear-box.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1 to 3, a kind of gear-box abnormal sound detection device 2, including the detection device 2 being arranged on gear case body 1 and the movable control device 3 placed, described detection device 2 is bolted on described casing 1 inwall, detection device 2 includes being embedded in the detection audio frequency detector 4 on device 2 surface, blue-tooth device 5 and being arranged on detection rechargeable battery 6 within device 2, described control device 3 includes PLC 7 and memorizer 8, controls device 3 with described detection device 2 by Bluetooth technology wireless telecommunications.
Sound when pre-recorded gear-box runs well in described memorizer 8, described control device 3 is internal is additionally provided with comparator 9, the gear operation sound input comparator 9 that detection device 2 will detect, sound when comparator 9 calls that in memorizer 8, pre-recorded gear-box runs well, carry out the comparison of sound frequency, if beyond sound frequency when running well, being then considered as abnormal sound, this noise reduction input store 8 will be preserved by controlling device 3, it is simple to subsequent analysis is consulted；Described control device 3 uses LED display 10, and power consumption is low.
Above-mentioned detection device 2 is arranged in each gear-box of plant equipment, and multiple detection devices 2 share one and control device 3, PLC 7 manage as a whole, and control device 3 and be placed on the place that it is easily observed.In plant equipment running, if abnormal sound being detected, Abnormal Sound tone signal is passed back control device 3 by Jian Cezhuanzhi 2, details can be checked by LED display 10, thus the sound source of quick lock in fault abnormal sound ground, take maintenance measure targetedly, it is to avoid the generation of sequential loss.It can find fault in early days, thus takes measures, it is to avoid the appearance of bigger problem, and easy to use, applied widely.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, being appreciated that and these embodiments can carry out multiple change without departing from the principles and spirit of the present invention, revise, replace and modification, the scope of the present invention be defined by the appended.
