The invention discloses a connecting device between the main support frame and the frame, which includes the bushing and sealing ring of the main support frame, a fixed hole on the frame, a support seat on the main support frame, a cavity on the support seat, an inner cavity of the main support frame bushing, two sealing rings on the left and right sides of the cylinder surface of the main support frame bushing respectively, and the inner wall of the cavity and the main support. Lubricant seals between the outer walls of the bracket bushing. Among them, the sealing ring can seal lubricating oil, prevent dust from entering the sliding gap of the main support, and use the relative sliding between the main support bushing and the main support mounting support seat to ensure that the main support in parking due to adequate lubrication, damping buffer can play a quiet, labor-saving, long service life of the main support and so on. Avoid the stagnation and abnormal noise of the traditional main support due to dust entering the main support mounting support seat, and avoid dust entering the main support mechanism. Under normal circumstances, only the sealing ring is worn out. It is convenient to repair and replace, and only the rubber sealing ring needs to be replaced.

一种主支撑架与车架的连接装置
本专利技术涉及连接装置
,尤其涉及一种主支撑架与车架的连接装置。
技术介绍
现有主支撑架与车架的连接,也就是主撑的安装结构,主支撑架安装在车架上,该安装结构的缺陷主要有:1、主撑安装支撑座直接与安装螺栓相接触,在主撑转转时,与螺栓产生摩擦,可导致螺栓主撑安装支撑座磨损;2、螺栓固定时需要调整螺栓预紧力,如果零部件尺寸存在细微偏差,可导致主撑旋转不灵活;3、主撑中润滑油没有密封,时间久时,可导致润滑油流失或消耗,起不到润滑作用;4、由于没有密封橡胶阻尼,泥沙、灰尘易进入主撑安装支撑座之间,引起卡滞或异响。
技术实现思路
有鉴于此,本专利技术的目的在于提供一种主支撑架与车架的连接装置,以提高润滑效果,延长使用寿命,避免由于灰尘进入产生卡滞、异响。为了达到上述目的,本专利技术提供如下技术方案:一种主支撑架与车架的连接装置,包括主支撑架衬套和密封圈,所述车架上设置有固定孔,所述主支撑架上设置有支撑座,所述支撑座上开设有空腔,所述主支撑架衬套内置在所述空腔中,所述密封圈为两个且分别设置在所述主支撑架衬套的圆柱面的左右两侧,将所述空腔的内壁与所述主支撑架衬套的外壁之间的润滑油密封。优选的,上述密封圈为阻尼橡胶密封圈。优选的,上述主支撑架衬套上开设有用于容纳两个所述密封圈的凹槽。优选的,上述主支撑架衬套与所述空腔为间隙配合。优选的,上述连接杆为螺杆,所述固定孔为通孔。优选的,上述连接杆为螺纹杆,所述固定孔为螺纹孔。优选的,上述主支撑架衬套的外端面上设置有外展的环形壁,所述环形壁卡在所述支撑座的外壁面上。优选的,上述环形壁与所述支撑座的外壁 ...
