Abstract

The invention discloses a hydraulic control system of a beam transporting vehicle, and belongs to hydraulic control systems of engineering machinery. The hydraulic control system is provided with not less than two crossbeams on both sides of the whole vehicle; a motor fault emergency disposal device and an explosion stack device are connected under each crossbeam respectively; a cab is arranged in front of and behind the hydraulic control system respectively; the rear part of the hydraulic control system is provided with a power cabin; the inside of the power cabin is symmetrically provided with engines; the engines are connected with a hydraulic pump; travel motors are connected with closed pumps through ball valves; and a hydraulic system pump and a travel motor fault isolation device are connected to one side of a main beam and are positioned at rear parts of the engines. The hydraulic control system has the advantages that: when the hydraulic control system of a vehicle breaks down, hydraulic elements such as ball valves, cushion valves and redundant pipelines and the like are adopted and reasonably configured, and an isolation method is adopted to separate the failure hydraulic elements out from the system so as to shorten maintenance time, reduce the shutdown time of machines, greatly reduce the difficulty of fault disposal, and improve the reliability of the system.

Description

technical field [0001] The invention relates to a hydraulic control system of engineering machinery, in particular to a hydraulic control system of a beam transport vehicle. Background technique [0002] The beam transporter is a large-scale construction machinery. The 900-ton beam transporter weighs 300 tons and has a total mass of 1,200 tons. At present, two methods are usually used to deal with the failure of the hydraulic system of this vehicle. The first is to replace the faulty hydraulic components on site, and the second is to remove the faulty hydraulic components on site and transport them to a repair shop for maintenance. Due to the limitation of on-site conditions or the lack of spare parts, failures are often not dealt with in a timely and effective manner, resulting in delays in the construction period and bringing great economic losses to users. Contents of the invention [0003] The object of the present invention is to provide a hydraulic control system of...
