Description
Technical field
The utility model belongs to harbour machinery technical field, is related to belt conveyer scale equipment, especially a kind of belt conveyer scale deviation inspection
Survey device.
Background technology
Belt conveyer scale refers to the weighing apparatus to being placed on belt and being carried out with the bulk material that belt continues through automatic weighing
Device, under normal circumstances belted electronic balance there was only weighing support, sensor and instrument composition, without driving motor grade power plant,
It only on belt conveyor by material weigh it is accumulative act on, the not size of control material flow.Belted electronic balance is port
The widely used material metage equipment of mouth, wherein belt balance weighing crane span structure is installed in conveying frame, when material passes through, metering
Carrying roller detects that weight of material on belt feeder, in weighing sensor, is generated one and be proportional to belt load by leverage
Voltage signal.There are one weighing sensors mounted in weighing on crane span structure on belt conveyer scale, during work, the material that will detect on belt
Weight is sent into weighing instrument, while is also fed into weighing instrument by the speed signal of tachogenerator belt conveyor, and instrument will be fast
It spends signal and carries out Integral Processing with weighing-up wave, obtain instantaneous flow and cumulative amount.
But often there is belt weight sideslip, weighing sensor damage, attachment device pine in belted electronic balance in use
Phenomena such as de-, causes the signal that the weighing unit at left and right sides of scale frame is fed back unequal, and difference is larger, seriously affects belt conveyer scale
Weighing precision.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of belt conveyer scale error measuring means, improve belt conveyer scale and are transporting
To the real time monitoring of load cell signal during row.
The technical solution of the utility model is as follows：
A kind of belt conveyer scale error measuring means, including weighing sensor, connecting rod, scale frame, signal amplifier, analog quantity
Module.
Scale frame includes preceding symmetrical scale frame and rear symmetrical scale frame, and connecting rod is divided into two groups of left and right, and it is preceding right that left group is mounted on
Claim the rear end of scale frame, right group is mounted on the front end of rear symmetrical scale frame, and weighing sensor is mounted at connecting rod, weighing and sensing
Device is connect by connection cables with signal amplifier input terminal, and signal amplifier output terminal is connect with analog module.
The mV voltage signals of weighing sensor export the current signal of 4-20mA, current signal through signal amplifier in proportion
Input analog module.
There is power circuit, isolation circuit, low drifting voltage amplifier circuit, output circuit, and signal in signal amplifier
The supply voltage 24V of amplifier.
The type selecting of analog module uses 1756-IF8.
The effect and benefit of the utility model be：
（1）The belt conveyer scale error measuring means when detecting that the output difference of belt conveyer scale both ends weighing sensor is excessive, lead to
It crosses PLC and alarm signal is transferred to host computer interface, operating personnel is reminded to notice that deviation occurs in belt conveyer scale, need contact repair people
Member checks that the whether heavy sideslip of belt, whether belt conveyer scale sensor damages, whether connecting rod loosens, and deviation is found from first time
The generation of failure；
（2）Beside electronic belt scale, the state of weighing sensor of belt scale is monitored in real time using electric signal, in time
It was found that the generation of deviation fault.
（3）Can effective dust, ensure weighing sensor of belt scale precision.
