Abstract
The utility model discloses a controller for controlling a bituminous mixture remixer to travel synchronously along with a paver. A computer chip is connected with a text display device through a PPI bus interface; a distance sensor outputs a current signal to an analog quantity I/O interface module; a computer chip PLC reads the numerical value of the current signal in the analog quantity I/O interface module outputted by the distance sensor through an internal bus; after internal calculation, the computer chip outputs a current signal to a proportional valve amplification board through the analog quantity I/O interface module; and the proportional valve amplification board controls the proportional valve of a variable pump according to the received current signal. The proportional valve of the variable pump controls the flow of the variable pump so as to control the rotating speed of the hydraulic motor, and in this way, the traveling speed of the bituminous mixture remixer can be controlled. The controller is simple in structure and low in cost and can accurately and quickly control the traveling speed of the bituminous mixture remixer, and effectively ensure the bituminous mixture remixer to travel synchronously along with the paver.
Description
Technical field
The utility model relates to a kind of controller for running of asphalt remixer, is that the asphalt remixer is followed paver synchronous walking controller specifically.
Background technology
In damaged asphalt surface hot reproduction repair process, at first that the pitch heating on damaged road surface is broken, be classified as the pitch band along the roadside, collect by asphalt remixer (claiming asphalt to promote remixer again), old material that the asphalt remixer will be collected and virgin material heating are mixed and stirred, be transported in the hopper of paver the road surface that paver will pave again and make new advances through the new and old asphalt heat recycling compound after mixing and stirring.Because paver work progress medium velocity changes, add that surface resistance changes asphalt remixer speed and can change within the specific limits, cause between asphalt remixer and the paver apart from strengthening or reduce, the compound that the asphalt remixer is carried can not accurately be fallen in the hopper of paver, influences the paving concrete pavement quality of paver.
By manually setting and manual control, speed is regulated inconvenient, low precision to the speed control of asphalt remixer fully at present.
The utility model content
Goal of the invention of the present utility model, be to overcome the problem that existing preparation of construction exists, provide a kind of asphalt remixer to follow paver synchronous walking controller, by the distance between ultrasonic distance sensor automatic measuring and controlling asphalt remixer and paver, can realize the synchronous walking of following of asphalt remixer and paver.
The asphalt remixer is followed paver synchronous walking controller, comprise that computer chip, text display, analog quantity input/output interface module, range sensor, proportioning valve amplify plate, variable output pump proportioning valve, computer chip links to each other with text display by the PPI bus interface; It is characterized in that: the range sensor output current signal is to the analog quantity input/output interface module, computer chip PLC reads the current signal numerical value of exporting from range sensor in the analog quantity input/output interface module by internal bus, through internal arithmetic, computer chip amplifies plate by analog quantity input/output interface module output current signal to proportioning valve again, and proportioning valve amplifies buttress according to the current signal control variable pump proportioning valve that receives.
The distance signal that computer chip obtains according to the parameter of setting and range sensor, by the flow of variable output pump proportional valve control variable output pump, thereby the rotating speed of control oil motor is realized the speed of travel of control asphalt remixer.
The utility model, simple in structure, with low cost, to the walking precise control of asphalt remixer, quick, can guarantee effectively that the asphalt remixer follows the paver synchronous walking.
Description of drawings:
Fig. 1 follows paver synchronous walking controller schematic block diagram for the asphalt remixer;
Fig. 2 follows paver synchronous walking controller control program block diagram for the asphalt remixer;
Fig. 3 follows paver synchronous walking controller circuitry synoptic diagram for the asphalt remixer.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1,3, the asphalt remixer is followed paver synchronous walking controller, comprise that computer chip PLC, text display TD400C, analog quantity input/output interface module EM235, ultrasonic distance sensor, proportioning valve amplify plate, variable output pump proportioning valve, computer chip links to each other with text display by the PPI bus interface; It is characterized in that: range sensor output 4-20mA current signal is to the analog quantity input/output interface module, computer chip PLC reads the current signal numerical value of exporting from range sensor in the analog quantity input/output interface module by internal bus, through internal arithmetic, computer chip amplifies plate by analog quantity input/output interface module output 4-20mA current signal to proportioning valve again, and proportioning valve amplifies buttress according to the current signal control variable pump proportioning valve that receives.
PLC reads in the setup parameter of text display TD400C, the ultrasonic distance sensor is sent the distance signal of paver and asphalt remixer into PLC, PLC handles, calculates according to setup parameter and distance signal, PLC sends control signal control ratio valve and amplifies plate, proportioning valve amplifies plate control variable pump proportioning valve, the flow of variable output pump proportional valve control variable output pump, thus the rotating speed of control oil motor is realized the control to the speed of travel of asphalt remixer.
Whether PLC judges paver and asphalt remixer in set distance range, if in set distance range at the uniform velocity, then the asphalt remixer is to set at the uniform velocity speed operation; Quickening set distance range if detect distance, then PLC increases travelling speed automatically, and to setpoint distance, the asphalt remixer travels with fixed speed again up to paver and asphalt remixer range recovery; If detect distance in the deceleration set distance range, then PLC reduces travelling speed automatically, and to setpoint distance, the asphalt remixer travels with fixed speed again up to paver and asphalt remixer range recovery.
