Abstract
The invention discloses a detecting device for the rotating speed of a stirring shaft. The detecting device comprises a rotating detection board, a proximity switch and a PLC. The rotating detection board is arranged on the detected stirring shaft, and is provided with a plurality of proximity protruding parts. The proximity switch is close to the rotating detection board, and is electrically connected with the PLC. The detecting device for the rotating speed of the stirring shaft is simple in structure and low in cost; the rotating speed of the stirring shaft of a stirring machine can be monitored in real time, alarm signals can be given out when the rotating speed of the stirring shaft is abnormal so that technicians can handle the abnormity in time, abnormity of temperature uniformity in heat treatment equipment is avoided, and the rate of finished heat treatment products is greatly increased.
Description
Technical field
The present invention relates to pick-up unit, especially a kind of shaft rotary speed detecting device.
Background technology
In heat treatment process, need to use mixing plant to the homogeneity of the homogeneity or quench media temperature that control high in-furnace temperature, and the rotational speed of shaft directly determines the working effect of mixing plant.In prior art, the rotational speed of shaft is measured by special checkout equipment, but this type of assay device structures is complicated, expensive, is difficult to large-scale promotion application.If but rotating speed abnormal monitoring not being carried out to shaft, when the rotating speed of shaft occurs abnormal, owing to not processing in time, the temperature homogeneity in heat treating equipment will be deteriorated, and finally cause the yield rate of heat treated article significantly to decline.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of shaft rotary speed detecting device, this structure of the detecting device is simple, with low cost, solve existing shaft rotational speed assay device structures complicated, expensive, be difficult to the technical matters applied.
According to technical scheme of the present invention: a kind of shaft rotary speed detecting device, comprise rotation and detect plate, proximity switch and PLC, described rotation detects plate and is arranged on tested shaft, and described rotation detects plate and is provided with several close to lug boss; Described proximity switch detects plate near described rotation, and described proximity switch is electrically connected with described PLC.
As a further improvement on the present invention, described rotation detects on plate and is arranged with two close to lug boss.
As a further improvement on the present invention, described rotation is detected plate and is arranged on tested shaft by ratchet wheel.
As a further improvement on the present invention, described shaft rotary speed detecting device also comprises alarm, and described alarm is electrically connected with described PLC.
As a further improvement on the present invention, described shaft rotary speed detecting device also comprises display screen, and described display screen is electrically connected with described PLC.
As a further improvement on the present invention, described display screen is touch-screen.
Compared with prior art, technique effect of the present invention is: structure is simple, with low cost, the real-time monitoring of the rotational speed to stirring shaft of stirring machine can be realized, alerting signal is sent when the rotational speed of shaft occurs abnormal, technician is facilitated to process in time, avoid the temperature homogeneity in heat treating equipment to occur abnormal, substantially increase the yield rate of heat treated article.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 1 comprises tested shaft 1, rotate and detect plate 2, proximity switch 3, PLC4, alarm 5, display screen 6, ratchet wheel 7 and close to lug boss 21.
Embodiment
For making above-mentioned purpose of the present invention, feature and advantage, can more becoming apparent, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The present invention is a kind of shaft rotary speed detecting device, the present embodiment comprises rotation and detects plate 2, proximity switch 3 and PLC4 (programmable logic controller (PLC)), rotation detects plate 2 and is arranged on tested shaft 1, proximity switch 3 detects plate 2 near rotating, and proximity switch 3 is electrically connected with PLC4.
Rotation detects plate 2 and is arranged on tested shaft 1 by ratchet wheel 7, and ratchet wheel 7 makes rotation detect the installation of plate 2 and dismounting becomes convenient.Rotation detects on plate 2 and is arranged with two close to lug boss 21, symmetrically arranged two close to lug boss 21 can not only impel proximity switch 3 produce close to induction, and add rotate detect the stationarity of plate 2 in rotary course.
Principle of work of the present invention is as follows: when tested shaft 1 rotates, and detects plate 2 rotate by ratchet wheel 7 driven rotary, when close to lug boss 21 near proximity switch 3 time, proximity switch 3 produces close to responding to and send a high level to PLC4; When leaving proximity switch 3 close to lug boss 21, proximity switch 3 loses close to responding to and sending a low level to PLC4.Low and high level alternately enters the counter of PLC4 inside, and calculates the rotating speed of tested shaft 1 by the calculation procedure of PLC4 storage inside.
As a preferred embodiment, the present embodiment also comprises the alarm 5 be electrically connected with PLC4, when the rotating speed of tested shaft 1 that PLC4 calculates and the ratio of rotating speed of target exceed preset value, the rotating speed of described shaft 1 occurs abnormal, alarm 5 will send alerting signal, notification technique personnel process in time, and the temperature homogeneity avoided in heat treating equipment occurs abnormal.
As a preferred embodiment, the present embodiment also comprises the display screen 6 be electrically connected with PLC4, and display screen 6, for showing the rotating speed of shaft 1 in real time, has further facilitated the real-time monitoring to shaft 1 rotating speed.Preferably, display screen 6 adopts touch-screen.
Above to invention has been the enough detailed description with certain singularity.Belonging to those of ordinary skill in field should be appreciated that, the description in embodiment is only exemplary, make under the prerequisite not departing from true spirit of the present invention and scope change and all should belong to protection scope of the present invention.The present invention's scope required for protection is undertaken limiting by described claims, instead of limited by the foregoing description in embodiment.
