Description

Automatic Oil Injection Device of Asphalt Rubber Wheel Roller

technical field

The utility model relates to an automatic fuel injection device of an asphalt rubber wheel roller, which belongs to the field of asphalt rubber wheel rollers.

Background technique

Tire rollers are mainly used for the compaction of various viscous and non-cohesive materials (gravel, sand, stabilized soil, asphalt concrete, etc.) Carry out compaction, during the compaction process, due to the kneading and pressing effect produced by the elasticity of the tire, the ply material can be displaced in all directions, forming a uniform, dense, and crack-free surface, thereby prolonging the service life of the road surface. It is widely used in road compaction.

For asphalt concrete, in addition to the basic function of compaction, it is also required that asphalt should not adhere to the surface of the tire during work, so as not to damage the paved asphalt pavement, thereby affecting the construction quality and construction efficiency. Aiming at the problem of asphalt sticking to tires, it is generally solved by equipping tire rollers with sprinkler systems or infrared heating devices. When using an infrared heating device, the anti-adhesion effect is better, but the cost is too high, and few customers will choose it. When using a tire roller equipped with a water sprinkler system, its cost is low and its structure is simple, but it is difficult to control the amount of water in the watering process: if there is less water, the air film produced on the surface of the tire is not enough, and the asphalt is still easy to adhere to; if there is too much water, It will cause the asphalt to cool down quickly and segregate easily, which cannot meet the construction requirements of grade pavement.

During the actual construction process on site, the construction personnel found that when there is oil or oil-water mixture on the tires, the asphalt cannot adhere to the tires, so workers will be arranged to follow the road roller with a mop sticky oil, and apply the oil to the tire surface with a mop to remove However, this method is prone to safety accidents, and has disadvantages such as uneven coating, high cost, and delay.

When the asphalt rubber wheeled roller is working, the heating tube is heated to heat the medium in the oil tank to make it vaporize, and then generate an oil-water mixture (the oil-water mixture is the medium to be ejected). As shown in Figure 1, when it is necessary to spray, close the switch, power on the system, and the circuit controller is powered on to control the reciprocating pump 7 to work (mainly control the opening and closing of the reciprocating pump 7, the speed of the pump, and then achieve the control of spraying oil-water mixture. Time and flow), the reciprocating pump 7 receives the instruction of the circuit controller and starts to pump the oil-water mixture, and the oil-water mixture is pumped out from the oil tank 9 through the ball valve 14, the filter 15, the reciprocating pump 7, the one-way valve 6, the three-way joint 5, Fuel injection pipe 3, finally sprays out by nozzle 1. When there is no need to spray, just turn off the switch. Finally, the oil-water mixture sprayed on the tire is uniform and timely, ensuring that the asphalt cannot adhere to the tire surface, with high safety and low cost.

In addition, at the same time, the function of cleaning the fuel injection pipe 2 and the spray head 1 can also be realized to prevent the occurrence of slight blockage caused by long-time inactivity. Generally, a delay relay of about 7 seconds is used, and this time is enough to blow out the remaining oil in the fuel injection pipe with air.

Preferably, the rubber tube 3 is fixedly connected to the three-way joint I5 or the three-way joint II18 through the hose clamp 4, which has a better fixing effect and prevents the rubber tube 3 from being pushed out due to excessive oil or gas pressure, resulting in waste of oil or gas and leakage accidents.
