Abstract

The invention discloses anti-slipping control equipment, a system, a method and engineering machinery which are used on a single-pump multi-motor walking device. The walking device comprises a first walking motor, a second walking motor and a walking main pump. The control equipment comprises an obtaining device and a control device. The obtaining device is used for obtaining signals representing flow in a hydraulic branch from the walking main pump to the first walking motor and / or signals representing flow in a hydraulic branch from the walking main pump to the second walking motor. The control device is used for judging whether the first walking motor or the second walking motor slips according to the flow signals. Under the situation that the first walking motor or the second walking motor slips, at least one of the following operations is carried out, namely an alarming device is controlled to carry out alarming; and a reversing valve in a hydraulic branch between a slipping motor and the walking main pump is controlled to carry out reversing, so that the hydraulic branch where the slipping motor is placed is cut off, and the slipping motor is in a free state. An anti-slipping function can be achieved on a single-pump double-motor walking system.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an anti-skid control device, system, method and construction machinery. Background technique [0002] At present, road rollers generally use a single-pump dual-motor travel system or a dual-pump dual-motor travel system. For the single-pump dual-motor walking system, a variable displacement pump is used to drive the front wheel motor and the rear wheel motor at the same time. The control system is simple, but it lacks anti-skid function. When passing obstacles and slippery roads, slipping will occur ; For the dual-pump and dual-motor walking system, the front wheel variable pump is used to drive the front wheel motor, and the rear wheel variable pump is used to drive the rear wheel motor. The displacement of the front and rear pumps is controlled by the controller to achieve the same speed of the front and rear motors. The two drive systems of the dual-pump dual-motor walk...
