Description
Technical field
The present invention relates to technical field of engineering machinery, be specifically related to a kind of vehicle tyre pressure control apparatus and hoisting crane.
Background technology
Along with national economy high speed development for years, especially country drops into strengthen year by year infrastructure construction, exploitation of mineral resources, makes some special-use vehicles with special purpose present explosive type development in recent years.This type of special-use vehicle has the main handling characteristicss such as operating environment is severe, operation intensity large, Active workings conversion is frequent, ground run road conditions are complicated.
Special-use vehicle refers to the automobile of special-purpose.General special-use vehicle and industrial and mineral can be divided into use classes to produce special-use vehicle.General special-use vehicle refers to the automobile for transporting and complete various different work; Industrial and mineral production special-use vehicle is customized design and has series of one's own, generally travels on single-purpose road or uses in specific region, can for fields such as mining, oil, hydraulic engineering, building engineerings.Be everlasting in harsh environment due to this automobile and work, therefore complete machine not only will have the excellent performance of field work, and lower chassis also needs to possess enough complete machines and passes through performance.
The transaction capabilities of special-use vehicle is not set forth herein, and under being mainly set forth in different pavement state herein, tire pressure is on the impact of special-use vehicle crossing ability.For truck-mounted drilling rig, be specifically described below:
Truck-mounted drilling rig travels soft surface, the muddy road surface along pool, seabeach, rugged gravel road surface, the wet and slippery ice and snow road etc. that road conditions contain desert dust storm.Landform complicated and changeable, often makes truck-mounted drilling rig can adapt to travel on soft surface, just can not adapt to travel on the hard pavements such as sandstone.Tracing it to its cause is truck-mounted drilling rig when passing through different road surface, and the best tire pressure of requirement is different.Such as, the load-carrying capacity of the fine sand loosened should be considered during the road surface of truck-mounted drilling rig by desertification, generally select the tire pressure of 0.10MPa ~ 0.3MPa.When travelling in the camp site of general well site class, consider the load-carrying capacity of hard viscosity layer, general selection tire pressure is 0.4MPa ~ 0.6MPa.When travelling on a highway, for improving Vehicle Speed, general selection tire pressure is 0.6MPa ~ 0.8MPa.
Can be obtained, for meeting special-use vehicle to the comformability on different road surface and crossing ability requirement, constantly adjusting knurl air pressure by upper example analysis.See Fig. 1, in prior art, heavy duty crane being provided with emergent air compensating system is tire 37 tonifying Qi.
Consider that heavy-duty vehicle brake system frequency of utilization is higher, the part comparisons such as gas circuit valve, gas circuit pipe, compressed air brake cylinder, drg easily lost efficacy, because of in the industry all by braking system gas circuit pressure setting at below 0.8MPa.Because the emergent air compensating system shown in Fig. 1 directly gets gas from complete machine brake system, therefore source of the gas top pressure is 0.8MPa.
Existing emergent air compensating system is that the process of tire 37 tonifying Qi is as follows: start the engine, filter from Air compressor 31 high pressure gas drying device 32 out, the high pressure gas of dry cleansing out flow through four return valves 34 again after reducing valve 33 reduces pressure, and be divided into 3 road gas be stored in corresponding air receiver from four return valves 34 gas out.Wherein, gas in first air receiver (i.e. air receiver I) 35 is used for complete machine use for brake system gas, gas in 3rd air receiver (i.e. air receiver III) 40 is used for other system supplymentary gas of complete machine, the gas when gas in the second air receiver (i.e. air receiver II) 39 is used for meeting an urgent need tonifying Qi.
If chaufeur is want, to tire 37 tonifying Qi pressure regulation, to be connect in one end of spiral tracheae 36 and the second air receiver 39 by gas path joint, the other end (with air-pressure gauge) of spiral tracheae 36 is connected with the tire tube valve of tire 37.After pipeline has connected, open the gas-filled switching tube 38 of the second air receiver 39, then the high pressure air in the second air receiver 39 just passes through pipeline charge and discharge in the tire 37 of depression.
Because the gaseous tension in the second air receiver 39 is less than 0.8MPa, so after once having inflated, the air pressure in tire 37 can only reach half pressure condition.If tire 37 needs higher air pressure, then need start the engine always, just have endlessly " high pressure air " charge and discharge to 37 li, tire in such second air receiver 39, but such gas replenishment process is repeatedly wasted time and energy.Be generally just can apply native system to meet an urgent need when chaufeur does not have other way really, otherwise other external gas source can be looked for come to tire 37 tonifying Qi or direct changing of tire 37.
Because venting air pressure is not easy to control, substantially venting pressure regulation need not be carried out to tire 37 by above-mentioned emergent air compensating system.
Visible, at least there is following problems in prior art:
1) have the heavy-duty vehicle of only a few that emergent air compensating system is housed at present, this emergent air compensating system bleed pressure is not high, and most cases is the source of the gas as air nutsetter during field maintenance.When for tire 37 tonifying Qi, superfeed pressure is not high, use when can be used as emergent, and real gives tire 37 tonifying Qi still by external air source.
2) existing emergent air compensating system can only give the tonifying Qi of a tire 37 at every turn, wastes time and energy.
3) existing emergent air compensating system function singleness, can only as interim tonifying Qi source of the gas, can not as venting source of the gas.When wagon drill cannot solve this problem by venting reduction tire pressure time " stranded " on desert soft surface, the road surface such as muddy, pool, beach.

Under yin, yang joint is in off-state, when there being gas to flow into from famale connector, due to the effect of famale connector contained spring, air is stopped sealing.
An outlet of gas pipe line can connect a tire 8, and having several exits and just can connect several tire 8, if having four outlets for gas pipe line, can be so that four tires 8 are inflated or exit.It should be noted that, inflation/deflation operation can be carried out by each tire 8 simultaneously, carries out respectively, can certainly carry out one by one after also can dividing into groups.
The outlet of each gas pipe line is all communicated with by the famale connector of gas source interface 10 with the first quick connector group 15.
Vehicle tyre pressure control apparatus preferably also comprises selector valve 4; Selector valve 4 is arranged in the gas circuit between the air extractor duct of tire pressure regulation air receiver 2 and the admission port of charge valve 3, and selector valve 4 is for controlling the gas circuit whether conducting at selector valve 4 place.The effect of selector valve 4 is equivalent to an air pressure main supply switch.In time not applying native system, close selector valve 4, cut off source of the gas supply, both for car load saves gas, also mitigate the load of each valve body off working state.If selector valve 4 disconnects, even if control cock is in inflation gear, also cannot inflate for tire 8.But selector valve 4 disconnects the bleed air operation not affecting tire 8.
Vehicle tyre pressure control apparatus also comprises the first air receiver (i.e. air receiver I) 18, second air receiver (i.e. air receiver II) 19, reducing valve 16 and four return valves 17; The admission port of reducing valve 16 is communicated with the air extractor duct of dryer 14, and the air extractor duct of reducing valve 16 is communicated with the admission port of four return valves 17, and two air extractor ducts of four return valves 17 are communicated with the admission port of the second air receiver 19 with the admission port of the first air receiver 18 respectively.
For hoisting crane, from Air compressor 1 gas out after dryer 14, again through reducing valve 16, then arrive the first air receiver 18 and the second air receiver 19, from the first air receiver 18 gas out as normal brake system gas, from the second air receiver 19 gas out as ancillary system gas.Above-mentioned two-way gas is all that vehicle uses gas normally.
For ease of monitoring the pressure in whole air-channel system, vehicle tyre pressure control apparatus also comprises air-pressure gauge 13, and air-pressure gauge 13 is arranged on gas pipe line.In inflation/deflation operation, can be known the air pressure in gas circuit in real time by air-pressure gauge 13, when the air pressure in gas circuit reaches predetermined value, chaufeur according to the reading of air-pressure gauge 13, can terminate charge operation or bleed air operation by operator brake control valve 5.
Air-pressure gauge 13 is the instruments measuring main line air pressure, is divided into dynamic air pressure and static air pressure.When gas replenishment process starts, each tire 8 is interconnected with gas pipe line, and because gas pipe line is all not identical with each tire 8 initial gas pressure, each several part air pressure flows mutually, and air-pressure gauge 13 shows dynamic air pressure.Static when last gas reaches balance, what now air-pressure gauge 13 showed is static air pressure, is gas pipe line and the final air pressure of each tire 8.
In the present embodiment, gas pipe line is preferably high pressure hose 12.High pressure hose 12 is generally fixed on vehicle frame bottom surface, and Main Function is that the high pressure air in air receiver III is caused each gas source interface 10.
Have the famale connector be threaded on each gas source interface 10 and on the tire tube valve 11 of each tire 8, the two ends of spiral tracheae 7 are all with male contact.When the male contact on spiral tracheae 7 one end and the famale connector grafting on gas source interface 10, when simultaneously on spiral tracheae 7, the male contact of the other end is with famale connector grafting on tire tube valve 11, the connection of whole piece gas channels.
How introduce below is tire 8 inflation boosting.When running at high speed under the hard pavement road conditions such as smooth cement, pitch or sandstone road for special-use vehicle, ground drag and the loss of tire 8 energy of deformation is reduced in order to improve tire 8 compressive load per unit area as far as possible, tire 8 inflation pressure is generally set up as about 0.75MPa, and detailed process is as follows:
First the pressure of pressure regulating valve on dryer 14 is adjusted to and bears 15% of pressure, then start the engine higher than tire 8 is maximum, enter air receiver III after the drying of high pressure gas drying device 14, system unloaded pressurize after pressure reaches the setting pressure of pressure regulating valve.Manually actuated control valve 5 handle is threaded to aerating position by pressure measurement position by chaufeur, now charge valve 3 is opened, aie escape valve 6 is closed, high pressure gas enter each arbor wheel tire 8 by high pressure hose 12 and spiral tracheae 7, during beginning, air-pressure gauge 13 shows dynamic air pressure, and after air-pressure gauge 13 reaches the standard pressure of 0.75MPa, the handle of manually actuated control valve 5 can be threaded to pressure measurement position by aerating position by chaufeur immediately, now charge valve 3 and aie escape valve 6 are all closed, and gas replenishment process terminates.After inflation terminates, air-pressure gauge 13 shows the air pressure of stable state, compared with the standard pressure of 0.75MPa, air pressure in tire 8 now may be slightly high or lower slightly, but error is substantially within 20KPa, therefore, the force value that during inflation, air-pressure gauge 13 shows is similar to the final inflation pressure of tire 8.
The gas flow of said process is: Air compressor 1 → dryer 14 → air receiver III → selector valve 4 → charge valve 3 → air-pressure gauge 13 → high pressure hose 12 → gas source interface 10 → the first quick connector group 15 → spiral tracheae 7 → the second quick connector group 9 → tire 8.Open again after it is noted that the stable gas pressure that selector valve 4 need be waited until in air receiver III.
Introduce below as tire 8 venting decompression.During for special-use vehicle by muddy soft surfaces such as sand ground, snow deposit, mire meadows, in order to ensure vehicle safety with smoothly by this road surface, need the air pressure (being generally about 0.3MPa) reduced to greatest extent in tire 8, increase high-wheeled ground contact area with this, specific operation process is as follows:
When having certain pressure in air receiver III, manually actuated control valve 5 handle is threaded to deflated position by pressure measurement position by chaufeur, now aie escape valve 6 is opened, charge valve 3 is closed, " high pressure gas " in tire 8 are exitted by the air extractor duct of aie escape valve 6, air-pressure gauge 13 shows dynamic air pressure, after air-pressure gauge 13 reaches the standard pressure of 0.3MPa, the handle of manually actuated control valve 5 is threaded to pressure measurement position by deflated position and namely completes bleed air operation, now charge valve 3 and aie escape valve 6 are all closed, air-pressure gauge 13 shows stable air pressure, namely the air pressure in tire 8, this air pressure can be approximately target air pressure 0.3MPa.
The gas flow of said process is: tire 8 → the second quick connector group 9 → spiral tracheae 7 → the first quick connector group 15 → gas source interface 10 → high pressure hose 12 → air-pressure gauge 13 → aie escape valve 6 → external world.
Introduce below as tire 8 pressure measurement.When manually actuated control valve 5 is in the normal state and pressure measurement position, now charge valve 3 and aie escape valve 6 are all closed.When spiral tracheae 7 connects tire 8, air-pressure gauge 13 shows dynamic air pressure, reaches each tire 8 tire pressure when mutually balancing, and the air pressure that now air-pressure gauge 13 shows is the stable air pressure of special-use vehicle tire 8.
The vehicle tyre pressure control apparatus that technique scheme provides, the improvement optimization to special-use vehicle air-channel system, namely on the basis not affecting the just conventional gas of complete machine, a kind of air-channel system that can detect and accurately regulate tire 8 internal pressure has been installed additional, achieve the pressure making chaufeur can regulate tire 8 according to different road surface characteristic, ensure the best in-use performance of tire 8 on different road surface and car load tractive performance, substantially can meet the crossing ability requirement on various road surface.In addition, technique scheme also has the following advantages:
1) when not using native system, disconnect the gas circuit between each tire 8 and each axle gas source interface 10 by spiral tracheae 7, each tire tube valve 11 and each tire 8 close pressurize automatically, and therefore tire 8 pressure maintaining performance is good.
2) each tire 8 can centralized and unified inflation/deflation, and also can divide into groups inflation/deflation as required, can also give single tire 8 inflation/deflation selectively.
3) chaufeur can select inflation or bleed air operation according to different road surface, can subjectively select inflation/deflation air pressure to improve the carrying capacity of special-use vehicle.
4) if want to reduce the inflation/deflation time, chaufeur can also improve the bleed pressure of native system by the pressure regulating valve on active adjustment dryer 14.
