Abstract

The invention provides a hydraulic control system and a road sweeper. The hydraulic control system comprises a first oil cylinder structure and a second oil cylinder structure, wherein the first oil cylinder structure is in driving connection with a sweeping mechanism; the second oil cylinder structure is connected in series with the first oil cylinder structure and is in driving connection with the sweeping mechanism; wherein the sweeping mechanism has a storage position and a working position. When hydraulic oil flows from the first oil cylinder structure to the second oil cylinder structure, the first oil cylinder structure and the second oil cylinder structure drive the sweeping mechanism to be switched from the storage position to the working position; and when hydraulic oil flows from the second oil cylinder structure to the first oil cylinder structure, the first oil cylinder structure and the second oil cylinder structure drive the sweeping mechanism to be switched to the storage position from the working position. The invention solves the problems that in the prior art, the electric control mode of a control system of a road sweeper is complex, the number of electric control elements is large, and consequently the number of places with faults is large.

Description

technical field [0001] The invention relates to the technical field of sanitation vehicles, in particular to a hydraulic control system and a road sweeper. Background technique [0002] In the prior art, the road sweeper includes a cleaning mechanism and a control system. The cleaning mechanism includes a sweeping disc, bristles and a hydraulic motor. The control system includes a yaw cylinder and a lifting cylinder, wherein the yaw cylinder and the lifting cylinder are connected to the cleaning mechanism. When cleaning the road surface, the yaw cylinder first drives the sweeping disc to deflect, then the lifting cylinder drives the sweeping disc to descend, and the hydraulic motor drives the sweeping disc to rotate to drive the bristles to rotate; after the cleaning operation is completed, the sweeping disc stops rotating, and the lifting cylinder drives first The sweeping plate rises, and then the deflection cylinder drives the sweeping plate to retract. [0003] However,...
