An annular groove and a chuck 8 matching the annular groove are circumferentially disposed at an upper end of the collar 6, the chuck 8 is rotatably engaged in the annular groove, and the chuck 8 passes through the screw 10 and the lower end of the sleeve The flange 9 is fixedly connected to axially fix the relative position of the collar 6 to the leg 3. The pendulum 5 end is hinged to the frame 1 by a hinge point a, and the other end is hinged to the end of the fixed connecting rod 4 without the collar 6 by a hinge point d. 1 to FIG. 5, FIG. 3 is a schematic diagram showing the working principle of the swinging mechanism of the leg according to the embodiment. As shown in the figure, the hinge points of the fixed connecting rod 4 and the swinging rod 5 are respectively hinged points before and after the swinging. And the hinge point d', the hinge point of the fixed connecting rod 4 and the rotatable sleeve 2 are respectively a hinge point c and a hinge point c' before and after the swing, wherein the hinge point a is located before the swinging hinge point d and the swinging hinge point d The connecting line 4 is connected to the front and rear of the line, and the fixed connecting rod 4 is kept parallel before and after the swing. In this embodiment, the fixed connecting rod 4 and the leg 3 are fixedly connected by the structure, so that the rotatable sleeve 2 and the leg 3 can be Rotating the connection causes the swing lever 5 to keep the starting position and the end position of the fixed connecting rod 4 parallel when swinging, so that the change of the traveling direction of the tire or the crawler on the leg 3 is not changed. In order to keep the starting position and the end position of the fixed connecting rod 4 parallel, it can be realized by providing a limiting device on the road milling machine, and the limiting device can be a positioning pin and/or a baffle, and can also be a bolt. For example, a locating pin or bolt can be mounted on the pendulum 5 to define a termination pin of the fixed connecting rod 4. Similarly, a locating pin or bolt is also mounted on the frame. Or directly welding a baffle to define the starting and ending position of the rotatable sleeve 2, and the specific mounting position of the positioning pin or the bolt or the baffle may be determined according to the swinging amplitude, the starting position and the ending position of the fixed connecting rod 4, so that It is ensured that the fixed connecting rods 4 are fixed in position before and after the swing and are parallel to each other.
在本实施例中， 还可以设置一个与摆杆 5连接的驱动装置， 该驱动装 置可以为油缸、 气缸或电机， 用以控制摆杆 5摆动， 该驱动装置可以连接 在摆杆 5中部， 也可以连接在摆杆 5的端部。 在其他的实施方式中， 固定连接杆 4可以铰接在摆杆 5的中部， 而摆 杆 5—端铰接在机架 1上， 另一端与驱动装置连接。 In this embodiment, a driving device connected to the swinging rod 5 may be provided. The driving device may be a cylinder, a cylinder or a motor for controlling the swinging of the swinging rod 5. The driving device may be connected to the middle of the swinging rod 5, It can be attached to the end of the swing link 5. In other embodiments, the fixed connecting rod 4 can be hinged to the middle of the swinging rod 5, and the swinging rod 5 is hinged to the frame 1 and the other end is connected to the driving device.
除了上述路面铣刨机的支腿摆动机构， 本发明还提供一种包括上述路 面铣刨机的支腿摆动机构的路面铣刨机， 该路面铣刨机的其它各部分的结 构参考现有技术， 本文不再赘述。 In addition to the leg swinging mechanism of the above-described road milling machine, the present invention also provides a road milling machine including the leg swinging mechanism of the above-described road milling machine, and the structure of other parts of the road milling machine refers to the prior art. This article will not go into details.
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在 本发明的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包 含在本发明的保护范围之内。 The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention.

工业实用性 Industrial applicability
本发明提供的支腿摆动机构采用双摇杆机构， 并将支腿作为可转动套 杆和固定连接杆的铰轴， 采用这种结构， 一方面， 因为固定连接杆与支腿 固定连接且摆动前后保持平行， 所以不会改变轮胎或者履带的前进方向， 另一方面， 在两个摇杵活动范围较小的情况下就可以使位于铰接点的支腿 有较大的位移范围， 且结构紧凑、 占用空间少； 而且还可以将固定连接杆 和可转动连接杆设置在不同的平面内， 这样就更能有效利用车体的空间， 为其他部件的布局腾出更多空间。 因此， 本发明具有工业实用性。 The leg swinging mechanism provided by the invention adopts a double rocker mechanism, and the leg is used as a hinged shaft of the rotatable sleeve and the fixed connecting rod, and the structure is adopted, on the one hand, because the fixed connecting rod is fixedly connected with the leg and swings The front and rear are kept parallel, so the direction of the tire or the track is not changed. On the other hand, the legs at the hinge point have a large displacement range and the structure is compact in the case where the two shake motion ranges are small. It can take up less space; it can also set the fixed connecting rod and the rotatable connecting rod in different planes, so that the space of the vehicle body can be more effectively utilized, and more space can be provided for the layout of other components. Therefore, the present invention has industrial applicability.
