Problems solved by technology
[0003] There are some methods to prevent the above problems in the prior art, such as using the method of stopping the vibration function when the vehicle speed is lower than the set minimum value and turning on the vibration when the vehicle speed is higher than the set speed, but this method will cause frequent vibrations when the vibratory roller is running. The start-stop vibration function affects the life of the vibration system of the vibratory roller, and limits the vibration of the vibratory roller when it is stopped
In addition, the above method cannot avoid the subsidence of the vibratory roller due to its heavy weight when it is stopped, so it has great limitations

Embodiment approach
[0024] According to one embodiment of the present invention, it is considered that the possibility of the vibratory wheel sinking during the running of the vibratory roller is very small. Therefore, in order to reduce power consumption and system complexity, the controller 300 may calculate the sinking depth of the vibrating wheel only when the vibrating wheel may sink (ie, the vibratory roller is running very slowly or stops). For example, the controller 300 can store a predetermined value in advance, and the range of the predetermined value can be set as the walking speed of the vibratory roller between 0-1 kilometers per hour (km / h), such as 0.5km / h, or the controller 300 may also receive a predetermined value, such as through manual input by an operator, which is not limited in the present invention. The controller 300 starts to collect the inclination angle in real time when the collected traveling speed of the vibratory roller is less than or equal to a predetermined val...

The invention discloses a method, a system and an engineering machine for preventing sinking of vibrating wheels of a vibratory roller. The method comprises the following steps of: detecting traveling speed of the vibratory roller; detecting an inclined angle between a vehicle body of the vibratory roller and the horizontal plane; and acquiring the traveling speed of the vibratory roller, acquiring the inclined angle in real time when the traveling speed of the vibratory roller is less or equal to a preset value so as to calculate sinking depths of the vibrating wheels, and warning when the calculated sinking depths of the vibrating wheels are larger than a warning depth.
Description
technical field [0001] The invention relates to the field of vibratory rollers, in particular to a method for preventing the vibrating wheels of the vibratory roller from sinking, a system for preventing the vibrating wheels of the vibratory roller from sinking, and a construction machine. Background technique [0002] In the field of construction machinery, vibratory rollers are widely used mechanical equipment in road construction. It mainly compacts various building and road construction materials through its own gravity and vibration, and is suitable for compacting various non-cohesive soils, crushed stones, crushed stone mixtures and various asphalt concrete, so it is widely used in road or road construction middle. At present, vibratory rollers can be mainly divided into single-drum vibratory rollers and double-drum vibratory rollers. The structural feature of the single steel wheel roller is that the front wheel is a steel wheel (vibration wheel), and the left and r...
