Description
Technical Field
The utility model relates to a hydraulic system, in particular to the hydraulic field of a working device of engineering machinery.
Background
The rubber-wheel road roller is an indispensable compaction device in pavement construction operation, the rubber-wheel road roller performs static compaction on a paving material through tires, compaction force acts on material particles along all directions, meanwhile, the elasticity of the tires generates a kneading effect on the material, and the degree of fit between concrete aggregate and aggregate is enhanced under the condition that the compacted layer material particles are not damaged, so that the pavement is uniform and compact.
Under working conditions such as strong wind and low temperature, the temperature of asphalt concrete after being paved is rapidly reduced, the phenomenon of sticking wheels occurs in the compaction operation of the rubber-wheeled road roller, the quality problems such as poor road surface flatness, local pitting surface, small pits and the like are easily caused, vegetable oil is often required to be smeared on tires to avoid the problem of sticking wheels to prevent sticking wheels, and most of current products are provided with special oil spraying systems to replace the traditional manual smearing scheme.
The oil sprinkling system of the rubber-tyred road roller generally comprises an oil tank, an oil pump, an electromagnetic valve, an oil sprayer, a hose, an oil sprinkling pipeline and the like, wherein the electric oil pump sucks oil from the oil tank during operation, the vegetable oil is sprinkled to the tire through the oil sprinkling pipeline and the oil sprayer after being filtered by the filter element and then passing through the electromagnetic valve, and the electromagnetic valve is used for adjusting the oil spraying quantity. The scheme through electrical heating needs the engine to provide energy for its electricity generation, and the electric stick appears burning out, electric leakage problem easily simultaneously, not only need maintenance, replacement cost can also lead to other safety problems. .
Disclosure of Invention
Aiming at the defects in the prior art, the utility model needs to solve the problems of high cost and unsafe oil sprinkling system.
In order to solve the technical problems, the oil sprinkling heating system of the rubber-tyred roller comprises an engine, a radiator, an oil sprinkling oil tank and an oil sprinkling function system, wherein the engine and the radiator form a heat dissipation loop, the oil sprinkling oil tank and the oil sprinkling function system form an oil sprinkling loop, the oil sprinkling heating system also comprises a connector and a heat exchanger, the heat exchanger is connected with the radiator in parallel through the connector, and the heat exchanger is closely installed in the oil sprinkling oil tank; the engine heat dissipation loop is heated through heat exchange with the oil sprinkling tank by using the heat exchanger, so that the energy consumption is reduced, and the heat efficiency is safely improved.
The electromagnetic valve is connected in series between the joint and the heat exchanger; the on-off control of the electromagnetic valve is controlled by the switching value or other control modes of the vehicle to play a role.
The device also comprises an ECU and a temperature sensor, wherein the temperature sensor is connected with the ECU and is arranged in the oil sprinkling oil tank, and the ECU is connected with the electromagnetic valve; the temperature sensor receives the ECU of the oil spraying tank temperature signal transmission, judges whether heating is needed, and controls the electromagnetic valve switch to form heat circulation.
And the joint is connected with the heat exchanger through the hose.
The water inlet of the heat exchanger divides water from the water outlet of the engine.
The utility model has the beneficial effects that: the engine waste heat heats the oil sprinkling oil tank through the ECU control electromagnetic valve by the heat exchanger, so that the effects of oil sprinkling safety, reliability, energy consumption reduction, energy conservation, environmental protection and low cost are realized.
