Abstract

The utility model discloses a liquid asphalt metering device, which comprises an asphalt tank for providing liquid asphalt, an asphalt metering cylinder used for metering liquid asphalt and outputting the liquid asphalt under a high pressure, and a driving cylinder and a PLC controller used for driving the asphalt metering cylinder. The asphalt tank is connected with the asphalt metering cylinder through a switch valve; a displacement sensor is mounted on the piston or the piston rod of the asphalt metering cylinder and is connected with a PLC controller; and the PLC controller controls a driving cylinder through signals of the displacement sensor. The utility model has a simple structure, can reliably work either under stronger vibration or in various placing positions, and ensures the metering accuracy of the liquid asphalt, as well as the quality of asphalt concrete.

Description

The liquid bitumen measuring apparatus
Technical field
The utility model relates to the road building machine field, relates in particular to a kind of liquid bitumen measuring apparatus.
Background technology
The pitch measuring apparatus that adopts on the asphalt mixing apparatus mainly contains two kinds now, and a kind of is to adopt weight sensor (being commonly called as piezoelectric sensor) and computer technology, and a kind of is to adopt weight displacement sensing and computer technology.These two kinds of Weighing devices are the static weighing technology, when the asphalt mixing apparatus is worked, because mixing apparatus work produces must vibrate and the difference of mixing apparatus putting position all makes the static weighing measuring accuracy greatly descend, the precision specific energy is uncontrollable below 2%, and is bigger to the quality fluctuation influence of asphalt.
The utility model content
The purpose of this utility model is to provide a kind of liquid bitumen measuring apparatus that can effectively improve measuring accuracy.
This liquid bitumen measuring apparatus that the utility model provides, comprise the pitch case that is used to provide liquid bitumen, also comprise be used to measure liquid bitumen and with the pitch metering cylinder of liquid bitumen high pressure output, be used to drive driving cylinder, the PLC controller of the piston of pitch metering cylinder, described pitch case is connected with the pitch metering cylinder by switch valve, on the piston of described pitch metering cylinder or the piston rod displacement transducer is housed, this displacement transducer is connected with the PLC controller, by the signal controlling described driving cylinder of PLC controller by displacement transducer.
Temperature owing to heated liquid bitumen in construction is a steady temperature, its density is certain, the pitch metering cylinder extracts weight of liquid asphalt from the pitch case and can measure by the volume that pitch occupies described metering cylinder, the utility model around this principle is installed in displacement transducer on the piston or piston rod of pitch power metering cylinder, receive the gravimetric value of input when the PLC controller, to be converted to the distance to a declared goal that piston should move and stored according to the corresponding density of asphalt temperature at that time, driving cylinder drives the piston motion of pitch metering cylinder, displacement transducer is sent to PLC with the real time data of piston shift position, when the data of displacement transducer output conform to the data of PLC controller, illustrate that the pitch weight in the pitch metering cylinder has reached the input weight value, the PLC controller issued instructions to Hydraulic Station controlling and driving cylinder and stopped action this moment.Thereby realize the output quantity of control liquid bitumen, make measuring accuracy not be subjected to the restriction of installation site and complete machine putting position, can not change measuring accuracy because of complete machine oscillation, the weight of liquid asphalt error in dipping is controlled at below 0.2%, thereby guarantees that the asphalt mixing ratio error is controlled in 0.5%.The utility model is simple in structure, no matter is under than the strong vibration state, still under various putting position states, all can work reliably, guarantees the accuracy of liquid bitumen metering, has guaranteed asphalt concrete quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As can be seen from Figure 1, this liquid bitumen measuring apparatus that the utility model provides, comprise pitch case 1, pitch metering cylinder 2, driving cylinder 3, pitch case 1 is connected with asphalt delivery cylinder 2 by switch valve 11, the piston of pitch metering cylinder 2 is driven by driving cylinder 3, on the piston of pitch metering cylinder 2 or the piston rod displacement transducer is housed, this displacement transducer 4 is connected with PLC controller 5, and PLC controller 5 is by Hydraulic Station 6 controlling and driving cylinders 3.
When the utility model uses, the operator will need the pitch emphasis numerical quantity input PLC controller 5 of usefulness earlier, PLC controller 5 is converted into the distance to a declared goal that piston should move in the pitch metering cylinder according to the density of liquid bitumen with this gravimetric value and stores, press start key then, the piston that driving cylinder 3 begins to drive the pitch metering cylinder moves right the liquid bitumen in the suction pitch case, displacement transducer 4 on the piston constantly is sent to the PLC controller with the position of piston information data, when the real time data that transmits when data in the PLC controller conform to, PLC sends instruction to Hydraulic Station 6 makes driving cylinder stop to move.Finish the metering of asphalt content this moment.When the driving cylinder inverted running, the piston in the pitch metering cylinder 2 is pushed away pitch, mixes and stirs with compound.The utility model is very accurate to the metering of pitch, and the asphalt mixing ratio error is controlled in 0.5%.
