Description
Technical field
The utility model relates generally to bridge construction field, is specifically related to a kind of bridge intelligent numerical control tensioning system.
Background technology
The structural safety sex chromosome mosaicism one of the main reasons of current bridge is that bridge beam body tensioning construction is lack of standardization, effective prestress is not enough, lacks effective quality control method, causes the serious curtailment in application life of bridge, many bridges, because pre-stress construction is defective, are forced to reinforce in advance.
In current engineering construction, the data that certificate demarcated by the jack first provided according to metrological supervision department during construction calculate the initial stress of stretch-draw needs control, the pressure gauge reading corresponding to design stress, carry out stretching process Stress Control according to the data calculated.Due to manometric accuracy of reading problem, the precision of each stage Stress Control in stretching process is made to be difficult to reach, simultaneously because constructor's error can have influence on the quality control of stretching process.
How to improve traditional tensioning process, accurately to beam body Shi Hanzhang, the human factor in work progress can be reduced, guarantee the quality that bridge prestress is constructed, become current bridge construction urgent problem.

Accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
Fig. 2 is the structured flowchart of system hardware.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of intelligent numerical control tensioning system mainly comprise be separately positioned on beam body two ends main stretch-draw jack, pressure sensor and displacement transducer, intelligent tensioning instrument and controller; Described pressure sensor and displacement transducer lay respectively at the both sides of jack, and described beam body connects ground tackle, is connected with jack by steel strand.
As shown in Figure 2, described controller comprises PLC, touch-screen, alarm, input and output mixing module, driver module, stepper motor and oil pump etc.; Described PLC is connected with described alarm, described touch-screen, described input and output mixing module respectively, and wherein PLC and touch-screen and input and output mixing module are bi-directionally connected; Described input and output mixing module is connected with the output of pressure sensing transmitter with the input of driver module and displacement sensing transmitter respectively; Described driver module exports and is connected with stepper motor, and described stepper motor is exported and is connected by choke valve with oil pump; Described displacement sensing transmitter and described pressure sensing transmitter export with choke valve and are connected.
In the present embodiment, carried out the aperture of control oil pump choke valve by the step number of control step motor, thus realize the control to stretching force.Pressure sensor and displacement transducer are fixed on jack, the stretching force of presstressed reinforcing steel and elongation value of stretching are changed into the signal of telecommunication and is input to control unit.
Another preferred embodiment, from touch-screen inputting process parameters and control command, PLC is passed to through serial ports, data are sent into output mixing module by calculating by PLC, have input and output mixing module to pass to driving stepper motor module and carry out control step motor, thus control oil pump choke valve regulates the size of oil pressure.Simultaneously, pressure sensing transmitter and displacement sensing transmitter send into the input module mixing module of control unit, carried out the process of data again by PLC, pass to touch-screen on the one hand and show, realize the closed-loop control to stretch-draw as feedback signal on the other hand.In stretching process when in stretching force and elongation value of stretching is undesirable, the warning of light and sound can be produced, simultaneously display alarm picture on the touchscreen.In stretching process, gather the data of returning is stored in PLC, data can be passed to generating report forms in host computer after stretch-draw terminates, to carry out follow-up treatment and analysis to data.
This intelligent numerical control tensioning system overcomes manual operation, visually observe the subjectivity and objectivity that brings with artificial judgment mode on operation, observation and misjudgment, combine computer technology, automatic control technology and mechanics of communication, the ability that there is stronger reliability and conform, programming is simple, easily grasped by technician, volume is little, low in energy consumption, lightweight, practical.
