Abstract
The present invention relates to a kind of protection method of rubber-tyred roller tire, described method includes following step: step one, drained by the air in the inner tube of a tyre of rubber-tyred roller tire; Step 2, in the inner tube of a tyre, inject liquid; Step 3, again to insufflation gas in the inner tube of a tyre to preset air pressure. The protection method of a kind of rubber-tyred roller tire of the present invention, safe and reliable, long service life and pressure road are effective.
Description
Technical field
The present invention relates to a kind of tire protection method, especially relate to a kind of method for being protected by the tire of rubber-tyred roller, belong to street roller technical field.
Background technology
At present, as a kind of pavement compaction machinery, rubber-tyred roller, mainly by pneumatic tyre, relies on self gravitation to be applied by laminated material Static compaction and kneading action; Consolidation effect and the reliability of rubber-tyred roller are all played a very important role by the air pressure inside of tire, thermotolerance, shape and work-ing life etc.
And in construction process, when particularly bituminous pavement being carried out multiple pressure, tire can be heated. A heat part is from asphalt, and a part is from heating system (a lot of rubber-tyred roller manufacturer in order to reduce pitch bonding and the demixing temperature between pitch and tire, and can devise tire heating system now). Now, tire temperature is often increased to 70 DEG C even 80 DEG C from normal temperature, and the air in the inner tube of a tyre is heated and can violent expand, and tire can be caused very big damage, the phenomenon even occurring blowing out by use so frequently. In addition, the gas expanded by heating in the inner tube of a tyre can make tire internal air pressure increase and deviate desirable air pressure, thus affects road surface compaction effect.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, it is provided that the protection method of the effective rubber-tyred roller tire of a kind of safe and reliable, long service life and pressure road.
The object of the present invention is achieved like this: a kind of protection method of rubber-tyred roller tire, and described method includes following step:
Step one, the air in the inner tube of a tyre of rubber-tyred roller tire is drained;
Step 2, in the inner tube of a tyre, inject liquid;
Step 3, again to insufflation gas in the inner tube of a tyre to preset air pressure.
The protection method of a kind of rubber-tyred roller tire in the present invention, above-mentioned steps two, it is necessary to the volume V of the liquid injecting the inner tube of a tyre is limited,;
Wherein, K is safety coefficient, and K=0.9;
V1For erecting to placement and inflating valve upward when the single inner tube of a tyre, it is possible to hold maximum volume when being no more than the liquid of inflating valve position;
, wherein V0For the volume of the single inner tube of a tyre.
The protection method of a kind of rubber-tyred roller tire in the present invention, the solution that the liquid in described step 2 should select high boiling point, low zero pour, corrodibility low and cheap.
The protection method of a kind of rubber-tyred roller tire in the present invention, described liquid is NaCl solution, CaCl2Solution and KCl solution etc.
A kind of rubber-tyred roller tire in the present invention, is filled with liquids and gases simultaneously in the tube of described street roller.
A kind of rubber-tyred roller tire in the present invention, the volume V of the liquid injected in the described inner tube of a tyre meets,;
Wherein, K is safety coefficient, and K=0.9;
V1For erecting to placement and inflating valve upward when the single inner tube of a tyre, it is possible to hold maximum volume when being no more than the liquid of inflating valve position;
, wherein V0For the volume of the single inner tube of a tyre.
A kind of rubber-tyred roller in the present invention, described rubber-tyred roller adopts above-mentioned tire.
Compared with prior art, the invention has the beneficial effects as follows:
1, gas hot expanding type is reduced: after the inner tube of a tyre of rubber-tyred roller tire of the present invention injects liquid, owing to the specific heat of liquid is far away higher than gas, liquid can absorb the heat of major part, the thermal expansion of gas is just considerably reduced like this when heating, tire is made to be not easy to occur deformation because of gas expansion, not only contribute to improving the work-ing life of tire, and be conducive to improving the pressure road effect of street roller;
2, high insulating effect: owing to the specific heat of liquid is much larger than gas, liquid is after absorbing heat, and temperature not easily changes, and can play the effect of insulation, it is possible to the negative impact that the bonding of reduction pitch and demixing temperature effect are brought;
3, center of gravity is reduced: and liquid 90kg can be poured due to single tire (if specification is 11.00-20-16PR), 11 rubber-tyred rollers taken turns just can be filled with the liquid of 1 ton nearly; Therefore can making the decentralization of whole street roller, rubber-tyred roller meeting place of working is more steady; Simultaneously filling liquid owing to price can be selected low, plays counterweight effect, so that it may indirectly to reduce the production cost of rubber-tyred roller significantly.
Embodiment
The protection method of a kind of rubber-tyred roller tire that the present invention relates to, described method includes following step:
Step one, the air in the inner tube of a tyre of rubber-tyred roller tire is drained;
Step 2, in the inner tube of a tyre, inject liquid;
Step 3, again to insufflation gas in the inner tube of a tyre to preset air pressure;
Concretely, in above-mentioned steps two, it is necessary to the volume V of the liquid injecting the inner tube of a tyre is limited,;
Wherein, K is safety coefficient, and K=0.9; The object of setting safety coefficient is to prevent from injecting excessive liquid;
V1For erecting to placement and inflating valve upward when the single inner tube of a tyre, it is possible to hold the maximum volume (V1 can be interpreted as the actual useful volume of tube) when being no more than the liquid of inflating valve position;
, wherein V0For the volume of the single inner tube of a tyre (can by V0It is interpreted as the theoretical volume of tube);
When injecting liquid, from V1And V2In choose less amount, and the amount that this is less is multiplied by safety coefficient K, thus obtains the volume amount of the liquid being filled with in the inner tube of a tyre;
Meanwhile, the solution that the liquid in step 2 should select high boiling point, low zero pour, corrodibility low and cheap, such as NaCl solution, CaCl2Solution etc. (can adopt a kind of single solution, it is possible to adopt multiple solution to mix, no matter which kind of mode is all within the protection domain of this patent).
Above-mentioned embodiment is only a prioritization scheme, and those skilled in the art improving according to what the design of this patent was done or changing all within the protection domain of this patent.
Further, utilize the tire of the rubber-tyred roller being simultaneously filled with liquids and gases in the inner tube of a tyre that this patent method obtains, and use the street roller of this tire all within the protection domain of this patent.
