Abstract
The utility model discloses an electromagnetic heating control system for an ironing board of a paving machine, which comprises a heating coil which is arranged on a wear-resistant base board of a box body of the ironing board, and the heating coil is sequentially connected with an electromagnetic heating controller and a temperature controller; and a temperature control probe is further arranged on the wear-resistant base board, and the temperature control probe is connected with a temperature controller by a signal wire. The electromagnetic heating control system has the advantages that a direct current generator is driven by an engine of the paving machine, a direct current is converted into high-frequency and high-voltage electricity by the electromagnetic heating controller, a magnetic field which changes at a high speed can be generated by the means that the high-frequency and high-voltage electricity which changes at a high speed flows through the coil, and innumerable small vortexes can be generated in the wear-resistant base board when a magnetic force line in the magnetic field is used for ironing the wear-resistant base board by a magnetism-permeable metal material, and the wear-resistant base board automatically heats at a high speed, so that the aim of heating the wear-resistant base board is achieved; and the system further has temperature control function. The system has the advantages of high heat efficiency, long service life, good safety and reliability, and the like.
Description
Technical field
The utility model relates to a kind of control system, especially relates to a kind of paver screed electromagnetism heating control system.
Background technology
Paver is applicable to the basic unit and the surface layer of the various materials that pave, the bituminous concrete road that is particularly useful for paving, and the RCC base layer material, Stabilized Soil etc. are to build the requisite key equipment of high-grade highway.Ironing machine is the key device of paver work, and ironing machine is the principal element that directly influences whole paver equipment paving concrete pavement quality, and paver must be heated to the ironing base plate about 120 ℃ before the bituminous mixture that paves.
Propane flammable gas heating and resistance wire heating are mainly adopted in the heating of paver screed both at home and abroad at present, and these two kinds of mode of heating efficient and reliability are low, and propane flammable gas heats not environmental protection.At present domestic and international manufacturer does not also adopt the precedent of electromagnetic heating technique.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of paver screed electromagnetism heating control system is provided, the temperature in the time of can guaranteeing screed work, and reliability height, safety and environmental protection can effectively improve the pavement spread quality.
The technical solution of the utility model is: a kind of paver screed electromagnetism heating control system, comprise the heater coil that is arranged on the wear-resisting base plate of screed casing, and described heater coil is connected with temperature controller with the electromagnetism heating controller successively; Temperature probe also is installed on wear-resisting base plate, and described temperature probe is connected with temperature controller by holding wire.
Described heater coil is bonded on electrician's plank, and electrician's plank is connected on the wear-resisting base plate of screed casing by connecting bolt.Distance between electrician's plank and the wear-resisting base plate is 8mm-10mm.Between described wear-resisting base plate and heater coil, be provided with the thick heat-barrier material of one deck 10mm.
Compared with prior art, the utility model has the advantages that: the motor by paver drives dc generator, convert direct current to high-frequency high-voltage that frequency is 20-40KHz by the electromagnetism heating controller again, the high-frequency high-voltage current that changes flows through the magnetic field that coil can produce the high speed variation at a high speed, when the magnetic line of force in the magnetic field presses wear-resisting base plate by the magnetic conductive metal material, can in wear-resisting base plate, produce countless little eddy current, make wear-resisting base plate heating at a high speed voluntarily itself, thereby reach the purpose of the wear-resisting base plate of heating; This system also has temperature control function.The utility model possesses thermal efficiency height, long service life, safety, advantage such as reliable.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a control principle schematic diagram of the present utility model;
Fig. 2 is a heater coil scheme of installation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of paver screed electromagnetism heating control system comprises power supply control master switch, temperature controller, electromagnetism heating controller, heater coil, wear-resisting base plate, temperature probe.
As shown in Figure 2, heater coil 1 is bonded on electrician's plank 3 by glue, electrician's plank 3 is connected on the wear-resisting base plate 4 of screed casing by connecting bolt 2, electrician's plank and wear-resisting base plate should keep the distance of 8mm-10mm, to guarantee to add thermal effect, temperature probe 5 is installed on the wear-resisting base plate, is used to detect the temperature of wear-resisting base plate, and by holding wire temperature signal is delivered to temperature controller.
Operating principle of the present utility model is: the motor by paver drives dc generator, convert direct current to high-frequency high-voltage that frequency is 20-40KHz by the electromagnetism heating controller again, the high-frequency high-voltage current that changes flows through the magnetic field that coil can produce the high speed variation at a high speed, coil board is installed on the wear-resisting base plate, when the magnetic line of force in the magnetic field presses wear-resisting base plate by the magnetic conductive metal material, can in wear-resisting base plate, produce countless little eddy current, make wear-resisting base plate heating at a high speed voluntarily itself, thereby reach the purpose of the wear-resisting base plate of heating, the thick heat-barrier material of one deck 10mm is arranged, in case the principal vertical line circle is heated itself between wear-resisting base plate and the heater coil.
The concrete operation method of native system in paver:
When paver screed need heat, ato unit, drive generator for electricity generation, opening power control master switch, open the electromagnetism heating controller, begin to heat screed, temperature probe detects the temperature of wear-resisting base plate, and this temperature signal passed to temperature controller, after screed is heated to 130 ℃ of design temperatures, temperature controller cuts out electromagnetic controller, stops heating automatically, and after the screed temperature was lower than 120 ℃ of setting values, temperature controller was opened electromagnetic controller, started heating function automatically.In the time of need not heating, close electromagnetic controller, powered-down control master switch.
