Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] figure 1 It is a structural schematic diagram of a milling machine according to an embodiment of the present invention. As shown in the figure, the front outrigger and the rear outrigger 13 of the milling machine jointly support the vehicle body 17, and the milling drum 15 is arranged at the rear of the vehicle body 17. During the construction process Among them, under the drive of the driving mechanism of the rear legs, the rear legs 13 automatically descend, and the operator starts the milling drum 15, and the milling drum 15 descends following the lowering of the legs to mill the ground. The milling machine of the embodiment of the present invention is equipped with a distance measur...

Abstract

The invention provides a control method and a control device of a milling machine and the milling machine. The milling machine comprises a distance measuring device and a control device. The distance measuring device is installed on a machine body of the milling machine and used for measuring the distance between the distance measuring device and the ground. The distance between the distance measuring device and the ground correspondingly changes with lifting of back support legs. The control device is respectively connected with the distance measuring device and a back support leg driving mechanism of the milling machine and used for calculating the distance between the bottom of a milling drum and the ground according to the distance between the distance measuring device and the ground. When the distance between the bottom of the milling drum and the ground is smaller than the preset distance threshold, the back support leg driving mechanism controls the back support legs of the milling machine to stop descending. By means of the technical scheme, the milling machine avoids safety hazards and milling blade damage caused by the fact that the milling drum supports the machine body caused by the fact that the milling drum is contacted with the ground in the non-starting state, improves reliability and safety, and resolves the problem of safety hazards caused by the fact that the milling drum supports the machine body.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a control method and control device for a milling machine and the milling machine. Background technique [0002] Milling machine is one of the main types of asphalt pavement maintenance construction machinery, mainly used for clearing sacks, oil waves, reticulation, ruts, etc. on asphalt concrete surfaces such as highways and urban roads. Because of its high working efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and the direct recycling of old milling materials, the milling machine is widely used in urban municipal road and highway maintenance projects. [0003] The performance of the milling machine directly affects the quality of the road milling work. In order to ensure the construction quality during the construction process, when the milling machine is working, the leveling device ...
