Description
Technical field
This utility model is related to belt slippage detection technique, in particular it relates to a kind of operation of loose unpacked material equipment of conveyer
During belt skidding detecting device.
Background technology
Belt feeder is widely used in the fields such as mineral products, harbour because of its transport that can expeditiously carry out goods, belt
Machine equipment due to various demands, needs the speed of service of real-time detection belt in running, at present to belt feeder operation speed
The detection of degree is mainly using belt contacts formula speed detector and the code-disc two ways that tests the speed is installed on cylinder.
It is, by fifth wheel and belt contacts, when belt runs, to drive fifth wheel fortune using belt contacts formula speed detector
OK, fifth wheel is connected with encoder, so as to measure the speed of service of belt.Because be by fifth wheel contact with belt surface into
Row velocity measuring, so vibration is inevitably resulted from belt running, can so cause the error of velocity measuring,
And fifth wheel and belt contact the abrasion that will also result in fifth wheel for a long time, so as to also one will be produced to velocity measurement
Fixed impact, while the speed measuring device damage frequency of this contact is higher, so maintenance load is also larger.
The metering system price that the code-disc that tests the speed is installed on cylinder is higher, and is arranged on roller end cover, when cylinder is tieed up
When repairing, code-disc need to be removed, workload is big, and the speed of the method detection, belt speed is only approximated, is changed in belt tension
When, it is larger with the actual correct velocity error of belt.
For belt feeder drawbacks described above existing in the course of the work, those skilled in the art propose belt conveyor for preventing torsion
Rotary device.Such as Publication No. CN205257261U, entitled《A kind of belt speed detection means》Chinese patent in, including sense
Should pop one's head in, speed sensor, cylinder and fixing device, inductive probe is several, is uniformly arranged on cylinder side with circumference,
Speed sensor is fixed on belt frame by fixing device, is fixed on the sensing on cylinder side by induction apparatuss monitoring and is visited
Head, is converted into the speed of belt feeder after the rotating speed for obtaining belt conveyer roller.However, in belt feeder in actual course of conveying,
Especially in the course of conveying of loose unpacked material, due to the abrasion between belt and cylinder, frictional force is caused to reduce and belt occur
There is opposite speed between cylinder, the phenomenon for belt slippage occur then, by the speed for monitoring cylinder, convert belt
Speed there is very big error, it is impossible in the case of symbolizing the true velocity of belt, easily cause the accumulation of logistics, shadow
Transfer efficiency is rung, under serious conditions, is rubbed between drivewheel and belt always, is easily caused belt and rubs, cause larger loss.
This also constitutes and requires further improvement pipe belt feeder slip detector, optimizing detection method, to solve to be deposited
Technical problem.
