Problems solved by technology

However, when the outriggers are unfolded using the related technology, since each outrigger can only be controlled individually, when the outriggers are operated, both sides of the construction machinery cannot be supported at the same time, which may easily cause the construction machinery to tilt. Uneven force, even lead to tipping

Abstract

The invention provides an outrigger control system, which includes a command sending unit, an outrigger controller and a solenoid valve for controlling the action of the outrigger, wherein: the command sending unit is used to send out a leg control command; the outrigger The controller simultaneously sends action instructions to the solenoid valves corresponding to the plurality of legs according to the leg control commands received from the command sending unit; the solenoid valves perform reversing according to the action instructions to control Action of the plurality of outriggers. Correspondingly, the present invention also proposes an engineering machine. Through the technical scheme of the invention, multiple outriggers can be controlled simultaneously, avoiding the situation of uneven force that may occur when controlling a single outrigger.

Description

technical field [0001] The invention relates to the technical field of outrigger control, in particular to an outrigger control system and an engineering machine. Background technique [0002] At present, most of the outriggers of construction machinery adopt the following structural forms: rear swing legs, X outriggers, front swing legs, folding outriggers, curved outriggers, etc. When unfolding outriggers, many of the outriggers need to be manually operated. The road valve rocker controls multiple outriggers to expand and support the ground respectively to form a square or trapezoid, which is used to support the weight of construction machinery and prevent overturning. However, when the outriggers are unfolded using the related technology, since each outrigger can only be controlled individually, when the outriggers are operated, both sides of the construction machinery cannot be supported at the same time, which may easily cause the construction machinery to tilt. Uneven...
