Description
Technical field
Of the present utility modelly relate to a kind ofly to prestressed concrete construction equipment, particularly relate to a kind of intelligent numerical control tensioning equipment that carries out the self-adaptive temperature that oil temperature controls.
Background technology
The intelligent tensioning equipment of just progressively promoting the use of in the market, although than traditional tensioning equipment advanced person a lot, the place that also comes with some shortcomings.For example, the temperature of regulator solution force feed automatically under the low environment of temperature guarantees that hydraulic oil works under design temperature.Hydraulic oil used in tensioning system, under different temperatures viscosity different, when flowing and the frictional resistance of pipeline different, when oil temperature is low, resistance is very large, the jack power efficiency is very low, even tensioning equipment can not use.When traditional tensioning equipment was encountered this situation, the workman re-used etc. after the oil temperature rising with the roasting fuel tank of fire bottom, and the temperature difference is brought error to measurement greatly sooner or later, and this phenomenon is more serious in northern building site.Once did experiment in the building site that the morning and evening temperature difference is large, when just having started the no-load running of oil pump jack early morning, oil pressure reaches 1.5MPa, moves after one hour, and during jack no-load running, oil pressure is reduced to 0.7MPa.Error reaches 0.8MPa, and trueness error reaches 1.6% and surpassed 1% required precision.In low temperature environment, the hydraulic oil retrogradation can not be worked, and the workman uses bottom the roasting fuel tank of fire, re-uses etc. after the oil temperature rising, and this way is that oil temperature control is not accurate, easily causes stretching force deviation to occur, thereby also further has influence on the pre-stress construction quality.
The utility model content
The purpose of this utility model just is to provide a kind ofly can carry out Real-Time Monitoring to the oil temperature of the hydraulic oil of pump, and can make oil temperature remain on the intelligent numerical control tensioning equipment of the self-adaptive temperature of design temperature scope.
Solution of the present utility model is such: the utility model comprises fuel tank, Hydraulic system and control system, be provided with electric heater and thermocouple sensor in described fuel tank, electric heater and thermocouple sensor are connected to control system, detect by control system the work that the fuel tank temperature is carried out analyzing and processing and controlled electric heater.
After adopting technique scheme, with electric heaters such as heating tube, thermocouples, the oil temperature of the hydraulic oil of pump is carried out Real-Time Monitoring, and a data message that collects feeds back to the programmable controller PLC in control system, by the PLC analyzing and processing and control electric heater hydraulic oil is heated, guaranteed that hydraulic oil temperature is in a reliable value, guarantee the power efficiency of jack, guaranteed the precision of stretch-draw.
The utility model has the advantages that and to carry out Real-Time Monitoring to the oil temperature of the hydraulic oil of pump, and can make oil temperature remain on the design temperature scope, guarantee construction quality.
Description of drawings
Accompanying drawing 1 is example structure block diagram of the present utility model.
Accompanying drawing 2 is structural representations of the present utility model.
The specific embodiment
As shown in Figure 1:
A kind of intelligent numerical control tensioning equipment of self-adaptive temperature is applied to intelligent tensioning numerical control pumping station system, comprises a main control pumping plant and one or more sub-control pumping plant, and the jack that is connected with pumping plant.
As shown in Figure 1, the present embodiment is to adopt main pumping station and auxiliary pump station to form tensioning equipment, wherein main pumping station comprises: 1, programmable logic controller PLC main frame, 2, touch-screen, 3, analog input output mixing module, 4, temperature-measuring module, 5, wireless communication module, 6, electromagnetic valve group, 7, frequency converter, 8, fuel tank, 9, motor, 10, plunger displacement pump, 11, Huo Le voltage-current sensor transmitting module, 12, thermocouple oil temperature heater, 13, thermocouple, 14, stretch-draw jack, 15, oil pressure or displacement transducer.The auxiliary pump station is take programmable logic controller PLC slave 16 as core, adopts simultaneously: 2, touch-screen, 3, analog input output mixing module, 4, temperature-measuring module, 5, wireless communication module, 6, the electromagnetic valve group, 7, frequency converter, 8, fuel tank, 9, motor, 10, plunger displacement pump, 11, Huo Le voltage-current sensor transmitting module, 12, thermocouple oil temperature heater, 13, thermocouple, 14, stretch-draw jack, 15, oil pressure or displacement transducer form the auxiliary pump station.
13 1 of thermocouples are contained in that the other end is connected with measuring temp module 4 in fuel tank, converting oil temperature to the signal of telecommunication is sent to programmable logic controller PLC main frame 1 or programmable logic controller PLC slave 16 and carries out temperature and control, when oil temperature was hanged down setting value, programmable logic controller PLC main frame 1 or programmable logic controller PLC slave 16 are controlled oil temperature heater 12 and are begun heating, until meet the oil temperature design load.Because oil temperature is too low, the dynamic viscosity of oil increases, and resistance increases, and the jack power efficiency reduces, and causes system's stretch-draw precise decreasing.So, at pumping plant and jack timing signal, during with the state of demarcation, the oil temperature of fuel tank memorizes in PLC, and the oil temperature when before later on each stretch-draw, control system gathers current oil temperature and the state of demarcation automatically relatively, if temperature is too low, automatically start the oil temperature heating system.
As shown in Figure 2:
the utility model comprises fuel tank 8, thermocouple 13, temperature-measuring module 4, analog input output mixing module 3 and thermocouple heater 12, described temperature-measuring module 4 is measured the temperature of fuel tank 17 interior hydraulic oil by thermocouple 13, temperature-measuring module 4 sends the oil temperature analog signal that detects to analog input output module 3, analog input output module 3 is converted into the data signal that programmable logic controller PLC main frame 1 can be identified, analog input output mixing module is sent to data signal programmable logic controller PLC main frame 1 again, heating or insulation by programmable logic controller PLC main frame 1 judgement thermocouple heater 12.
