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 a leg control system which comprises a command transmitting unit, leg controllers and electromagnetic valves for controlling actions of a plurality of legs. The command transmitting unit is used for transmitting a leg control command; the leg controllers simultaneously transmit action instructions to the electromagnetic valves of the legs according to the received leg control command transmitted from the command transmitting unit; and the electromagnetic valves are reversed according to the control instructions so as to control the actions of the legs. Correspondingly, the invention provides an engineering machine. According to the technical scheme, the leg control system and the engineering machine have the advantages that the legs can be controlled simultaneously, and problems of uneven stress and the like when a single leg is controlled are avoided.

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...
