A side plate comprises a lower plate body, an upper plate body and a middle plate body, the height of the middle plate body relative to the lower plate body is adjusted through a first height adjusting mechanism so that the overall height of the side plate can be adjusted, a fixing device comprises a lifting column, a second height adjusting mechanism and a limiting sleeve, and after the height of the side plate is adjusted, the height of the side plate can be adjusted. The height of the lifting column is adjusted through a second height adjusting mechanism so that the height of the limiting sleeve can be adjusted, and the height of the limiting sleeve can be matched with the height of the break angle of the upper plate body so that sleeving and fixing can be achieved; meanwhile, in the using process of the side plate, due to the fact that the two folded corners of the top of the upper plate body are limited through the limiting sleeves of the two fixing devices respectively, the upper plate body can be driven to ascend and descend in a small range through the first height adjusting mechanism at the moment, and connection and separation of the upper plate body and the two limiting sleeves are achieved; and in addition, the lifting columns and the limiting sleeves are connected to the folded corners of the upper plate body, so that the side plates can be reinforced, and the structural stability of the whole side baffle is improved.

    本发明公开了一种半挂车主框架,侧板包括下板体、上板体和中间板体,通过第一高度调节机构调节中间板体相对下板体的高度以实现对侧板的整体高度进行调节,固定装置包括升降柱、第二高度调节机构和限位套,在侧板的高度调节后,通过第二高度调节机构调节升降柱的高度以实现对限位套的高度进行调整,以使得限位套的高度能适配上板体的折角处的所在高度以实现套设固定;同时在侧板使用过程中,因上板体顶部两个折角处分别通过两个固定装置的限位套进行限位,此时可通过第一高度调节机构带动上板体小幅度升降,以实现上板体和两个限位套的连接和脱离;另外升降柱、限位套连接在上板体的折角处,可实现对侧板进行加固,提高整个侧挡的结构稳固性。
