Problems solved by technology
If this method is used to control the outriggers of mobile construction machinery, the left and right front outriggers will oscillate and rise due to problems such as adjustment lag, which cannot effectively solve the problem of synchronous lifting, and the body may tilt left and right and outriggers hang in the air. , or even the danger of tipping over
[0006] Therefore, there is a need for an outrigger control technology that can solve the problems that the outriggers of outrigger construction machinery cannot be lifted and lowered synchronously and the rear outriggers need to be manually adjusted to ensure the balance of the fuselage.

The present invention provides an outrigger control system, comprising: a controller, an electromagnetic proportional valve and an inclination sensor, wherein the electromagnetic proportional valve is arranged on the oil circuit of the outrigger of the outrigger type construction machinery, and the inclination sensor acquires the The inclination angle of the outrigger type construction machinery, the controller is connected to the inclination sensor and the electromagnetic proportional valve, and adjusts the energizing current of the electromagnetic proportional valve corresponding to the corresponding outrigger according to the inclination angle obtained by the inclination sensor, Adjust the lifting speed of the corresponding legs. According to the technical solution of the present invention, the lifting speed of the left front outrigger and the right front outrigger of the outrigger type construction machinery can be realized to be consistent, and the rear outrigger can also follow the front outrigger to automatically lift up and down to maintain the balance of the fuselage. The invention also provides an outrigger type construction machine and a control method for outriggers.
Description
technical field [0001] The present invention relates to the field of engineering machinery, in particular to outrigger type engineering machinery, outrigger control system and method. Background technique [0002] The outrigger type construction machinery is widely used in various construction sites. During the process of walking or construction, it needs to adjust the height of the fuselage by lifting four outriggers. According to the requirements of construction, among the four outriggers of outrigger construction machinery, the left front outrigger and right front outrigger can be controlled independently, and the rear two outriggers can be controlled synchronously (see figure 1 ). [0003] At present, during the construction process of outrigger construction machinery, the height of the left front outrigger and the right front outrigger can be set. Sensors are installed on the left and right sides of the fuselage to detect the height of the outriggers. Outriggers are u...
