Abstract

The invention discloses a swinging device for a leg of a milling machine, comprising a leg and a position switching device; the position switching device includes a connecting arm, a central gear, a planetary gear and a driving device; one end of the connecting arm is fixed to the leg connected, the other end of which is hinged to the frame of the milling machine through a hinged shaft; the central gear is connected to the frame and coaxially arranged with the hinged shaft; the planetary gear is fixedly arranged on the connecting arm and connected with The sun gear cooperates; the driving device is connected with the planetary gear or the sun gear, and is used to drive the planetary gear to rotate around the hinge shaft. Compared with the prior art, the center gear, planetary gear and driving device occupy less space, and can be easily installed on small and medium-sized milling machines, so that the small and medium-sized milling machines can conveniently switch the position of the outriggers, and reduce the Labor intensity of workers. In addition, the present invention also discloses a milling machine provided with the above-mentioned swinging device for the supporting legs of the milling machine.

Description

technical field [0001] The invention relates to road surface milling technology, in particular to a milling machine and a swinging device for its legs. Background technique [0002] At present, the milling machine is the main equipment for asphalt pavement and cement pavement maintenance construction machinery; it is mainly used for excavation and maintenance of asphalt concrete and cement concrete surface courses such as expressways, first-class highways, urban roads, airports, freight yards, parking lots, etc. renovation. The milling machine can efficiently mill out the cracks, ruts, looseness, subsidence and surface function attenuation of the asphalt pavement and other road surface diseases; moreover, it can also efficiently deal with the arching, misalignment, peeling and peeling of the cement concrete pavement , Potholes, pitted surfaces, exposed, loose and polished. The milling machine has high working efficiency, simple construction process, easy control of milling...
