Description
Technical field
The utility model relates to technical field of engineering machinery, is 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 year by year and strengthens 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 is large, Active workings conversion is frequent, ground run road conditions complexity.
Special-use vehicle refers to the automobile of special-purpose.Use classes, can be divided into general special-use vehicle and industrial and mineral and 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 on single-purpose road, travels or uses in specific region, can be for fields such as mining, oil, hydraulic engineering, building engineerings.Be everlasting in harsh environment and work due to this automobile, 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, is mainly set forth in the impact of tire pressure on special-use vehicle crossing ability under different pavement states herein.Taking truck-mounted drilling rig as example, be specifically described below:
The road conditions of travelling truck-mounted drilling rig contain the soft surface of desert dust storm, the muddy road surface along pool, seabeach, rugged gravel road surface, wet and slippery ice and snow road etc.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 while passing through different road surface, the best tire pressure difference of requirement.During such as road surface by desertification of, truck-mounted drilling rig, should consider the load-carrying capacity of loosening fine sand, generally select the tire pressure of 0.10MPa～0.3MPa.In the time travelling in the camp site of general well site class, consider the load-carrying capacity of hard viscosity layer, generally selecting tire pressure is 0.4MPa～0.6MPa.In the time of running on expressway, for improving Vehicle Speed, generally selecting tire pressure is 0.6MPa～0.8MPa.
Can obtain by upper routine analysis, for meeting comformability and the crossing ability requirement of special-use vehicle to different road surfaces, often adjusting knurl air pressure.Referring to Fig. 1, in prior art, on 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 below 0.8MPa.Because the emergent air compensating system shown in Fig. 1 is directly to get 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 four return valves 34 of flowing through after reducing valve 33 decompression again, are divided into 3 road gas from four return valves 34 gas out and are stored in corresponding air receiver.Wherein, gas in the first air receiver (being air receiver I) 35 is for complete machine use for brake system gas, gas in the 3rd air receiver (being air receiver III) 40, for other system supplymentary gas of complete machine, is used gas in the situation of the gas in the second air receiver (being air receiver II) 39 for emergent tonifying Qi.

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, need start the engine always, in such the second air receiver 39, just have endlessly " high pressure air " to charge and discharge 37 li, tire, but such gas replenishment process is repeatedly wasted time and energy.Be generally in the situation that chaufeur does not have other way really, just can apply native system to meet an urgent need, otherwise can look for other external gas source to come to tire 37 tonifying Qi or direct changing of tire 37.
Because venting air pressure is not easy to control, substantially need not above-mentioned emergent air compensating system to tire 37 pressure regulation of exitting.
Visible, in prior art, at least there is following problems:
1) have at present the heavy-duty vehicle of only a few that emergent air compensating system is housed, this emergent air compensating system bleed pressure is not high, and most cases is the source of the gas of the air nutsetter used during as field maintenance.When for tire 37 tonifying Qi, tonifying Qi pressure is not high, can be used as use while meeting an urgent need, and real gives tire 37 tonifying Qi still by external air source.
2) existing emergent air compensating system can only be given tire 37 tonifying Qi at every turn, wastes time and energy.
3) existing emergent air compensating system function singleness, can only serve as interim tonifying Qi source of the gas, can not serve as venting source of the gas.When cannot reducing tire pressure by venting when " stranded " on the road surfaces such as desert soft surface, beach pool is muddy, wagon drill solves this problem.

Taking hoisting crane as example, from Air compressor 1 gas out after dryer 14, pass through again 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 is used 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 know in real time the air pressure in gas circuit by air-pressure gauge 13, when the air pressure in gas circuit reaches predetermined value, chaufeur can, according to the reading of air-pressure gauge 13, finish charge operation or bleed air operation by operator brake control valve 5.
Air-pressure gauge 13 is instruments of measuring main line air pressure, is divided into dynamic air pressure and static air pressure.In the time that 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.Last gas is static while reaching balance, and 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 to each gas source interface 10.
On each gas source interface 10 and on the tire tube valve 11 of each tire 8, have the famale connector being threaded, the two ends of spiral tracheae 7 are all with male contact.When the famale connector on male contact and gas source interface 10 on spiral tracheae 7 one end is pegged graft, when on spiral tracheae 7, the famale connector on male contact and the tire tube valve 11 of the other end is pegged graft simultaneously, whole piece gas channels is connected.
Introduce below and how to inflate and to boost for tire 8.While running at high speed under the hard pavement road conditions such as smooth cement, pitch or sandstone road taking special-use vehicle as example, reduce ground drag and tire 8 energy of deformation losses in order to improve tire 8 compressive load per unit area as far as possible, tire 8 inflation pressuries are general to be 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 higher than tire 8 maximums and bears 15% of pressure, then start the engine, enters air receiver III, system unloaded pressurize after pressure reaches the setting pressure of pressure regulating valve after high pressure gas drying device 14 is dry.Chaufeur is threaded to aerating position by manually actuated control valve 5 handles by pressure measurement position, 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, when beginning, air-pressure gauge 13 shows dynamic air pressure, and when air-pressure gauge 13 reaches after the standard pressure of 0.75MPa, chaufeur can be threaded to pressure measurement position by the handle of manually actuated control valve 5 by aerating position immediately, now charge valve 3 and aie escape valve 6 are all closed, and gas replenishment process finishes.After inflation finishes, 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, and therefore, the force value that when 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 → tires 8.It is noted that after selector valve 4 need be waited until the stable gas pressure in air receiver III and open again.
Introduce below as tire 8 venting decompressions.Taking special-use vehicle during by muddy soft surfaces such as sand ground, snow deposit, mire meadows as example, in order to ensure vehicle safety with smoothly by this road surface, need to reduce to greatest extent the air pressure (being generally 0.3MPa left and right) in tire 8, increase high-wheeled ground contact area with this, specific operation process is as follows:
Have certain pressure in air receiver III time, chaufeur is threaded to deflation position by manually actuated control valve 5 handles by pressure measurement position, now aie escape valve 6 is opened, charge valve 3 is closed, " high pressure gas " in tire 8 exit by the air extractor duct of aie escape valve 6, air-pressure gauge 13 shows dynamic air pressure, when air-pressure gauge 13 reaches after the standard pressure of 0.3MPa, the handle of manually actuated control valve 5 is threaded to pressure measurement position by deflation position and completes bleed air operation, now charge valve 3 and aie escape valve 6 are all closed, air-pressure gauge 13 shows stable air pressure, be 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 worlds.
Introduce below as tire 8 pressure measurement.Pressure measurement position when manually actuated control valve 5 is in the normal state, now charge valve 3 and aie escape valve 6 are all closed.In the time that spiral tracheae 7 is connected tire 8, air-pressure gauge 13 shows dynamic air pressure, and while reaching the mutual balance of each tire 8 tire pressure, the air pressure that now air-pressure gauge 13 shows is the stable air pressure of special-use vehicle tire 8.
