Abstract

The invention discloses a grabbing arm type trash remover robot hydraulic control system. A main motion structure of a trash removing robot in the system is divided into a rail moving vehicle and a grabbing arm, and the rail moving vehicle is driven by a servo motor and used for conveying the grabbing arm to a trash removing position. The grabbing arm is driven by a hydraulic system, namely, threerotary joints of a large arm, a small arm and a grab bucket. The scheme of pump control and valve control is introduced, each oil cylinder is independently provided with a hydraulic pump set, the flow of a motor rotating speed control pump is changed in the manner that a variable-frequency or servo motor drives a hydraulic pump, the control system calculates the required flow of the oil cylindersin real time according to track planning, the variable-frequency or servo motor drives the hydraulic pump to set the flow according to the flow slightly larger than the required flow, and the movement direction and speed of the hydraulic cylinder are accurately controlled through a servo proportional valve. The problem of accurate control over the hydraulic oil cylinders is solved, meanwhile, theproblems of large heating and large energy losses of a servo pump station are solved, and therefore energy saving of the system is achieved.

Description

technical field [0001] The invention relates to a hydraulic control system, in particular to a robot hydraulic control system for an arm-grabbing type cleaning machine, and belongs to the technical field of control of the arm-type cleaning machine. Background technique [0002] The grab arm type cleaning robot relies on the hydraulic mechanical arm to forcefully push the garbage to the bottom of the grid along the grid, so that the dirt can be gathered together. The hydraulic grab has a strong grasping force and can grab all the dirt at one time. At the same time, the claw teeth of the grab bucket penetrate the grille, so that the grille is completely cleaned from top to bottom, and can effectively clean various types of dirt, and the cleaning effect is good. The cleaning ability has been greatly improved, and the concentrated congestion of high-strength upstream sewage can be cleaned up in a timely and effective manner in front of the trash rack at the intake and drainage o...
