Bulldozer soil loosening device branch angle pin automatic hole replacing system and method

Abstract

The embodiment of the invention provides a bulldozer soil loosening device branch angle pin automatic hole replacing system and method. The system comprises an oil cylinder pressure sensor, an oil cylinder position sensor, a controller and a hydraulic electromagnetic valve; the oil cylinder pressure sensor and the oil cylinder position sensor are used for sensing the pressure in an oil cylinder and the space position of the oil cylinder; the controller is connected with the oil cylinder pressure sensor and the oil cylinder position sensor, obtains a pressure sensing signal through the oil cylinder pressure sensor, obtains a position sensing signal through the oil cylinder position sensor, and controls the hydraulic electromagnetic valve of the oil cylinder according to the pressure sensing signal and the position sensing signal; and the hydraulic electromagnetic valve is connected with the controller, and is used for controlling pressure transmission of the oil cylinder under control of the controller, and completes the branch angle pin automatic hole replacing motion. By means of the bulldozer soil loosening device branch angle pin automatic hole replacing system and method in the embodiment, the soil loosening device branch angle depth adjustment efficiency and the intelligent degree can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of construction machinery equipment, and in particular to a system and method for automatically changing holes of a ripper pin of a bulldozer. Background technique [0002] The ripper of the bulldozer is mainly used for complex and harsh working conditions such as soil loosening and rock layer stripping in earthwork construction, and the operating load is heavy. Due to the country's restrictions on explosives such as explosives in recent years, more and more rippers of bulldozers are used for mining, rock stripping and other operations. Due to the complex soil quality of the working surface, operators need to frequently adjust the depth of the branch angle (that is, replace the branch angle holes) to suit different job objects. [0003] figure 1 The schematic diagram of the structure of the bulldozer ripper and its supporting angle pin is shown. see figure 1 , such as soft soil,...

Problems solved by technology

The depth adjustment of the current ripper corners is entirely manual, that is, the operator first pulls out the corner pins, then adjusts the upper and lower positions of the beam, and then inserts the corner pins to complete the entire adjustment process. The line of sight is poor due to occlusion. At the same time, the accuracy of the vertical adjustment of the beam is not easy to control. Since the entire adjustment process is completely dependent on the operation of the operator and has not been realized intelligently, the adjustment of the depth of the support angle is time-consuming and laborious, the operation efficiency is low, and even the phenomenon of support angle falling off occurs. There is a greater safety hazard. Hidden danger
