Folding ladder stand of milling machine
The invention discloses a milling machine folding ladder stand, which comprises a ladder stand seat fixed on the side part of a milling machine frame, the ladder stand seat is connected with a quadrilateral mechanism composed of an upper ladder stand, an upper connecting plate, a lower connecting plate and a lower ladder stand, and the upper connecting plate and the lower connecting plate rotate around pin shafts of the upper ladder stand and the lower ladder stand. The length of the lower crawling ladder is adjusted through parallel movement of the quadrilateral mechanism along the up-down direction of the milling machine body; the upper ladder stand is provided with a damping rubber pier and connected with one end of a gas spring, and the other end of the gas spring is connected with an upper connecting plate; the lower ladder is connected with one end of the rubber plate, and the other end of the rubber plate is connected with the pedal. The ladder stand can be folded up and down and turned over, the maximum depth milling operation can be met after the ladder stand is folded, and a driver can get on and off a vehicle conveniently after the ladder stand is unfolded; and in addition, the transportation width can be reduced after overturning.
本发明公开了一种铣刨机折叠爬梯，包括固定在铣刨机车架侧部的爬梯座，爬梯座与上爬梯、上连接板、下连接板、下爬梯组成的四边形机构连接，上连接板与下连接板围绕上爬梯与下爬梯的销轴转动，下爬梯通过四边形机构沿铣刨机车身上下方向平行移动调整爬梯长度；上爬梯设有减震胶墩，上爬梯与气弹簧一端连接，气弹簧另一端与上连接板连接；下爬梯与橡胶板一端连接，橡胶板另一端与踏板连接。本发明爬梯既可以上下折叠又可以翻转，折叠后可以满足最大深度铣刨作业，展开后可以方便驾驶员上下车辆；另外翻转后也可以降低运输宽度。
