Abstract
The utility model discloses a rotatory speed detector of (mixing) shaft, know board, proximity switch and PLC including rotatory examining, rotatory examining knows that the board setting is on being surveyed the (mixing) shaft, rotatory examining knows that it is close the bellying to be equipped with a plurality of on the board, proximity switch is close to the rotatory knowledge board of examining, proximity switch with the PLC electricity is connected. The utility model discloses simple structure, low cost can realize the real time monitoring to the rotation rate of mixer (mixing) shaft, send alarm signal when the rotation rate appearance of (mixing) shaft is unusual, make things convenient for the technical staff in time to handle, avoid the temperature homogeneity in the equipment for heat treatment to appear unusually, have improved the yield of thermal treatment product greatly.
Description
Technical field
The utility model 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.
Utility model content
The utility model is for 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 the technical solution of the utility model: 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 further improvement of the utility model, described rotation detects on plate and is arranged with two close to lug boss.
As further improvement of the utility model, described rotation is detected plate and is arranged on tested shaft by ratchet wheel.
As further improvement of the utility model, described shaft rotary speed detecting device also comprises alarm, and described alarm is electrically connected with described PLC.
As further improvement of the utility model, described shaft rotary speed detecting device also comprises display screen, and described display screen is electrically connected with described PLC.
As further improvement of the utility model, described display screen is touch-screen.
Compared with prior art, technique effect of the present utility model 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 utility model;
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 utility model, feature and advantage, can more becoming apparent, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model 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 utility model 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.
The enough detailed description with certain singularity is carried out to the utility model above.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 utility model and scope change and all should belong to protection domain of the present utility model.The utility model scope required for protection is undertaken limiting by described claims, instead of limited by the foregoing description in embodiment.
