Abstract

The utility model relates to a motor speed measuring device. The device comprises a motor, wherein a reflective sticker is arranged on the outer side surface of a rotating part of the motor, a position outside the rotating part at a distance of 0.5-10cm from the reflective sticker is provided with a proximity switch in an opposite manner, and the proximity switch is respectively connected with a programmable logic controller and a power supply. The motor speed measuring device has the advantages of stable performance, high reliability, and low cost of spare parts.

Description

A kind of motor speed measuring device
Technical field
The utility model relates to technical field of metallurgical equipment, and particularly, the utility model relates to a kind of motor speed measuring device.
Background technology
At present existing pick-up unit or the method for testing the speed of equipment is scrambler or tech-generator; but because production on-site environment is poor; be subject to the restriction of various environment and condition; often occur that object, dust damage scrambler or; cause and throw switch or power supply burns out fault; be easy to produce device damage, and spare part somewhat expensive, to production, bring very large waste to cause and cause a large amount of stop times.
Utility model content
The purpose of this utility model is, a kind of motor speed measuring device is provided, and this device performance is stable, and reliability is high, and spare part expense is low.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of motor speed measuring device, described device comprises motor 1, on rotary part 2 lateral surfaces of motor 1, a reflection plaster 3 is set, rotary part 2 is outer is oppositely arranged an approach switch 4 in the position of 0.5~10cm apart with reflection plaster 3, described approach switch 4 is connected with power supply 6 with programmable logic controller (PLC) (Programmable Logic Controller is called for short PLC) 5 respectively.
Preferably, rotary part 2 is outer is oppositely arranged an approach switch 4 in the position of 2cm apart with reflection plaster 3.
The model of described approach switch 4 is EM5-G18-CP1 or IG5221.
Described programmable logic controller (PLC) 5 is S7-300 switching input module or S7-400 switching input module.
Principle of work of the present utility model is: when approach switch is passed through in the rotation of the reflection plaster on rotary part, approach switch sends high level pulse signal, PLC is one state, program starts counting, when reflection plaster passes through approach switch each time, approach switch all sends a pulse signal, and 1 pulse is 1 circle, from program, calculate the rotation number of turns of unit interval, thereby calculate rotating speed.
When the utility model detects, Test Field only has approach switch without other detecting elements, has realized without consumable accessory consumption, has reduced spare parts cost.
The utility model has solved the drawback that scrambler uses, simple and practical, has prevented the misoperation that external environment condition brings; guaranteed that speed detects accurate; production equipment is moved automatically, to reducing the downtime, improve production operational availability and there is definite meaning.
The utility model is used approach switch to test the speed to rotary part, and this device circuit is simple, installs reliable; the features such as usable range is wide, and environmental requirement is low, and reliability low detection with high investment is accurate; the robotization that is widely used in metallurgy industry is controlled, and reduces in a large number spare part expense and disorderly closedown.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model motor speed measuring device;
Reference numeral: 1, motor; 2, rotary part; 3, reflection plaster; 4, approach switch; 5, programmable logic controller (PLC); 6, power supply.
Embodiment
With the drawings and specific embodiments, the utility model is described in further detail below.
As shown in Figure 1, a kind of motor speed measuring device, described device comprises motor 1, on rotary part 2 lateral surfaces of motor 1, a reflection plaster 3 is set, rotary part 2 is outer is oppositely arranged an approach switch 4 in the position of 2cm apart with reflection plaster 3, and described approach switch 4 is connected with power supply 6 with programmable logic controller (PLC) 5 respectively.
The model of described approach switch 4 is EM5-G18-CP1.
Described programmable logic controller (PLC) 5 is S7-300 switching input module.
The utility model power supply is that on-site cable lays, approach switch is arranged on the basis outside rotary part, firmly not yielding, detects reflection plaster and is fixed on rotary part lateral surface, the position suitable of guaranteeing itself and approach switch, can reliably be sent to PLC and realize the object that tests the speed.
It should be noted that, the model of approach switch is EM5-G18-CP1 in the present embodiment, but in other embodiments, the model of approach switch can change according to need of production, as IG5221 etc.; Secondly, in the present embodiment, programmable logic controller (PLC) is S7-300 switching input module, but in other embodiments, can adopt as required other programmable logic controller (PLC)s, such as S7-400 switching input module etc.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described.Although the utility model is had been described in detail with reference to embodiment, will be understood by those skilled in the art that, the technical solution of the utility model is modified or is equal to replacement, do not depart from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
