Abstract

A method for controlling stalling of a milling drum during reversing of a milling machine includes sensing the oil pressure on a working oil way connected with a working port (D) for reversing oil-taking of a walking hydraulic motor (5) of the milling machine; and when the oil pressure is equal to or larger than a preset oil pressure value, controlling a reversing valve corresponding to at least one of a hydraulic clutch (2) and a milling drum driving belt tensioning cylinder (1) of the milling machine to reverse so as to enable at least one of the hydraulic clutch and the milling drum driving belt tensioning cylinder to relieve pressure. In addition, the invention further provides a device for achieving the method and the milling machine comprising the device. According to the method and the device, reversing signals can be obtained without a mechanical input mode, reliability and safety are greatly improved through the oil pressure sensing mode, the operation is reliable, performances are stable, and the device is not easy to damage and long in service life.

Description

Technical field [0001] The invention relates to a control method of a milling machine, in particular to a method for controlling the stop of the milling drum when the milling machine is reversed. Further, the present invention also relates to a device for controlling the stop of the milling drum when the milling machine is reversed. In addition, the present invention also relates to a milling machine, which includes the above-mentioned device for controlling the stop of the milling drum when the milling machine is reversed. Background technique [0002] The milling machine belongs to the construction machinery widely used in road engineering construction. Among them, the milling drum of the milling machine is one of the important parts of the milling machine. The cutter is installed on the milling drum. When the planer moves forward, the milling machine can plan the road surface so as to make the road smooth and facilitate subsequent construction. [0003] The safety technical st...
