Description
Technical field
The present invention relates to pitch sprinkling paver field, particularly relate to a kind of air-path control system for pitch sprinkling paver.
Background technology
In the past, in highway maintenance construction, often adopted traditional construction technology mode, i.e. interval before and after emulsified asphalt distribution vehicle and bituminous pavement paving machine, the construction operation mode that works alone. This construction, is sprayed onto emulsified asphalt binder on the road surface of pre-protection in advance with special pitch sprinkling car often, and then asphalt-spreader is spraying bituminous mixture laying on the road surface of Over emulsfication pitch. This type of operating type not only efficiency of construction is low, and labour intensity is large, and very easily causes environmental pollution, the situation of waste of material.
At present, for the problem existing in above-mentioned construction technology, although there is the Multifunctional asphalt spread paver that spread function and asphalt paving function are integrated in one on market, as Fu Gele is equipped with the S1800-2JET paver of sprinkling module device and the RP600S paver of Xu work science and technology, but they are in the time spraying construction operation, can only utilize the open and close of air-control device control shower nozzle to realize continuous sprinkling, and the uniformity that cannot spray according to the sprinkling amount control of the speed of paving, paving width and setting.
For fear of the appearance of the problems referred to above, the patent No. is the flusher that 201110440290.8 Chinese invention patent has proposed a kind of transverse shifting, the main feature of this device be advance at paver movably guide rail bracket of one is set in a lateral direction, shower nozzle is fixed on guide rail bracket, the method of utilizing guide rail bracket translational speed and the paver speed of paving to match, realizes the control of sprinkling amount under the pattern that paves at a slow speed. After sprinkling completes, utilize gas path device that compressed air is imported in spraying pipeline, emulsified asphalt residue is blown to and in asphalt tank, carries out flushing of pipeline. This flusher, although can realize to a certain extent the control of sprinkling amount under the pattern that paves at a slow speed, the gas path device increasing, can only be used for the flushing of bitumen pipeline. So extra track-type facilities and the gas path device increasing of this device, has not only increased product cost, has strengthened paver host machine integral installing space, and complex operation, is difficult for realizing.
The patent No. is that 201120469666.3 Chinese utility model patent has proposed a kind of air pressure type emulsified asphalt asphalting device, this device is that compressed air is imported in emulsified asphalt tank body, utilize compressed-air actuated pressure that emulsified asphalt is pressed onto in spraying pipeline, by shower nozzle, emulsified asphalt is sprayed onto on ground. After sprinkling finishes, air pressure is imported in spraying pipeline, the residue in spraying pipeline is blown to and in asphalt tank, carries out flushing of pipeline. This vapour-pressure type flusher, although the effect of gas path device has been guided to sprinkling and the flushing of bitumen pipeline, but it is the sprinkling amount of uncontrollable emulsified asphalt, and compressed air exists pressure control unstable and by the potential risk of emulsified asphalt oxidation to harness emulsion, so this device is difficult for realizing in actual applications.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of air-path control system for pitch sprinkling paver, can make sprinkling amount controlled accurately, can also rinse spraying pipeline.

Detailed description of the invention:
As shown in Figure 1, native system is mainly made up of parts such as air compressor machine 11, cooling line 12, drying device 13, gas receiver 14, air-operated solenoid valve 15, pneumatic actuator 16, pneumatic ball valve 17, air gauge 18, manual ball valve 19, check valves 110, except this, also should comprise impulse controller 2, diesel oil filling box 21 and emulsified asphalt pipeline accessory system, emulsified asphalt pipeline accessory system comprises emulsified asphalt tank 22 and bitumen pipeline 3.
In the time carrying out air-channel system stringing, can install and stringing with reference to Fig. 2 and accompanying drawing 3. Air compressor machine 11 is arranged on diesel engine, produces source of the gas by Diesel Driven air compressor machine 11, being then bent into snakelike shape with the stainless steel tube of 6-8 rice becomes cooling line 12, and is placed in the front end of paver radiator; By bolt, the drying of drying device 13 is arranged on the left side beam of paver, and air inlet is connected with cooling line 12, gas outlet is connected with the gas receiver 14 that is arranged on paver diesel fuel tanks side; By pneumatic accessories, gas circuit is divided into seven tunnels, spray respectively and below that pneumatic control component subsystem 4, side spray pneumatic control component subsystem 5, the manual ball valve 19, the check valve 110 that spray in pneumatic control component subsystem 6, pneumatic ball valve 17, air gauge 18 and flushing line are connected to form a complete air-channel system 1 above, in each sprinkling pneumatic control component, with pneumatic joint, air-operated solenoid valve 15 be connected with pneumatic actuator 16 and be arranged on bitumen pipeline 3. One end of pneumatic ball valve 17 is connected with the refluxing opening of emulsified asphalt pipeline accessory system 3, another port is connected with the port of emulsified asphalt tank 22, the pneumatic control mouth of pneumatic ball valve 17 is connected with a branch road of air-channel system 1, by " switching " of the pneumatic ball valve 17 of pneumatic control, control off-load and pressure foundation that emulsified asphalt pipeline 3 refluxes, thereby realize beginning and the finishing control of spraying operation. Emulsified asphalt spread paver, before starting, should guarantee that each systemic-function is normal, and air-channel system should be without phenomenons such as gas leakage, power-off. Pave before construction, should first start air-channel system 1, observe and barometricly indicate whether in about 8bar, whether drying device 13 carries out normal exhaust to judge the normal of its function.
In the time of emulsified asphalt spraying operation, by pneumatic ball valve 17, bitumen pipeline 3 is opened completely, make the emulsified asphalt in pipeline fully mobile, form reflux cycle. Then pneumatic ball valve 17 is closed, make bitumen pipeline 3 set up certain pressure; After spreader starting, impulse controller 2 is exported " open and close " of control signal control air-operated solenoid valve 15, and then handle pneumatic actuator 16 and carry out " stretch, contract " action, thereby the pulsed that drives shower nozzle to complete emulsified asphalt is sprayed and is controlled, after sprinkling has paved, open the oil returning tube of bitumen pipeline 3 by pneumatic ball valve 17, make bitumen pipeline 3 pressure off-loads, finish spraying operation.
After emulsified asphalt has sprayed, need to clean bitumen pipeline 3. Now, first by diesel oil filling box 21, diesel oil is filled in bitumen pipeline 3, then close diesel oil filling box 21, by opening manual ball valve 19, air pressure is incorporated in bitumen pipeline 3, close the return line of bitumen pipeline 3 simultaneously by pneumatic ball valve 17, and open and spray Control Component, so just the emulsified asphalt residue in bitumen pipeline 3 can be blown out to sprinkling pipeline and carry out washing and cleaning operation.
The use of system of the present invention is not limited in this, can also air-channel system 1 be drawn to a branch for the paver flushing of pitch residue around by external pipeline, so air-channel system extensibility of the present invention is good, simple to operate, take up room little, be especially specially adapted to the engineering machinery of this limited space of pitch sprinkling paver.
