Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of ironing machine of paver and paver.
Background technology
Asphalt paver be applicable to pave basic unit and the surface layer of various materials; Being to be applicable to pave the special-purpose machinery of the road materialss such as bituminous mixture road, RCC base layer material, Stabilized Soil material and graded broken stone, is to build speedway and the indispensable key equipment of high-grade highway.
Ironing machine is the groundwork device of paver, and its function is by the heat mixture tamping and the ironing that are transported in hopper.The ironing machine of general paver is made up of draft arm (large arm), vibrating beam, screed, thickness adjusting mechanism, camber guiding mechanism etc.Screed and vibrating beam are arranged on the rear portion of spiral distributor, are provided with foremost material scraping plate, and end face baffle plate is equipped with at screed two ends.The space that screed, front retainer plate and left and right end face baffle plate contain claim to pave groove or the chamber that paves, end face baffle plate can make paving layer obtain flat edges.Left and right two draft arms are hinged on central rack, and whole ironing machine is suspended on fuselage afterbody by lift cylinder, and the control oil cylinder of self-level(l)ing device is contained in the connecting point position of draft arm and frame, realizes different paving thicknesses in order to the elevation angle of automatic adjustment screed.Whole mechanism forms a set of suspension arrangement.When work, ironing machine is quick condition in laying.
As shown in Figure 1, ironing machine is mainly by left end baffle plate 1, left 750 screeds 2, left 1000 screeds 3, left freely-moving mangle (can be also non-freely-moving mangle) 4, left back arm 5, left main screed 6, camber indicating device 7, camber adjusting device 8, right main screed 9, right back arm 10, right freely-moving mangle (can be also non-freely-moving mangle) 11, top compressing cylinder 12; Right 1000 screeds 13, right 750 screeds 14, right-hand member baffle plate 15 form.
Electric heating system is installed on ironing machine, the electrically heated rod of electric heating system is arranged on left 750 screeds 2, left 1000 screeds 3, left freely-moving mangle 4, left main screed 6, right main screed 9, right freely-moving mangle 11, right 1000 screeds 13, right 750 screeds 14, and each electrically heated rod is parallel with one another.This electric heating system has the following disadvantages: when the electrically heated rod fault on certain section of screed, as short circuit or electric leakage, will cause whole screed electrical heating all can be cut off; Electrically heated rod on whole screed applies same electrical heating voltage, can cause being clipped in middle screed temperature rise the fastest, and outermost screed temperature rise is the slowest, makes whole screed transverse temperature inconsistent, while paving, there is demixing temperature, affect spreading quality; Electrical heating voltage only has disconnection or closed two states, makes ironing machine temperature fluctuation large; Because whole screed has at most 36 electrically heated rods, in the time breaking down, the troubleshooting time is long, and difficulty is large.
Summary of the invention
In view of this, the present invention proposes a kind of ironing machine and paver of paver, to solve above-mentioned technical problem.
On the one hand, the invention provides a kind of ironing machine of paver, comprise at least two sections of screeds, electric heater unit is all installed on the base plate of every section of screed, each electric heater unit includes electrically heated rod and control box, and control box comprises adjusting detecting unit; Regulate detecting unit for to heater open circuit, short circuit, detection of electrical leakage, the voltage of electrically heated rod is regulated or cut off Voltage-output.
Further, also comprise display unit, display unit is used for showing electrically heated rod status information.
Further, control box also comprises control module, regulates detecting unit, according to the control signal of control module, the voltage of electrically heated rod is regulated or cut off Voltage-output.
Further, temperature pick up is all installed on the base plate of each screed, temperature pick up is connected with control module.
Further, control box also comprises communication unit, and communication unit communicates for the master control system of control box and paver, regulates detecting unit, according to the control signal of master control system, the voltage of electrically heated rod is regulated or cut off Voltage-output.
A kind of paver is also provided in addition, has comprised the ironing machine of above-mentioned paver.
The present invention proposes a kind of ironing machine and paver of paver, corresponding electric heater unit is installed on every section of screed, the control box of each electric heater unit detects electrically heated rod state, to heater open circuit, short circuit, detection of electrical leakage, the voltage of electrically heated rod is regulated.If certain electrically heated rod generation open circuit of certain section of screed or the fault of short circuit or electric leakage, can not affect the function of the electric heater unit of other section of screed, guarantee that the continuation of construction is normally carried out, produce economic benefit.The electrically heated rod voltage of every section of screed can regulate separately, can not cause being clipped in that section of middle screed intensification of screed the fastest, and outermost that section of screed intensification is the slowest, makes the inconsistent problem of all screed transverse temperatures.In addition, electric heater unit of the present invention fix a breakdown convenient.
Brief description of the drawings
The accompanying drawing that forms a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the ironing machine structural representation of prior art paver;
Fig. 2 is the heater schematic diagram of ironing machine of the present invention.
Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figure 2, a kind of ironing machine of paver, comprises at least two sections of screeds, and electric heater unit is all installed on the base plate of every section of screed, and each electric heater unit includes electrically heated rod and control box, and control box comprises adjusting detecting unit; Regulate detecting unit for to heater open circuit, short circuit, detection of electrical leakage, the voltage of electrically heated rod is regulated or cut off Voltage-output (comprising voltage swing adjusting, the adjusting of voltage on-off etc.);
