可伸缩式半挂车
摘要：
一种可伸缩式半挂车，其包括可伸缩式车架及安装于车架下方的行走机构，所述车架包括：前架；中架，所述中架的前端与前架的后端固定连接为一体，所述中架包括左、右两中架纵梁，其后端两侧均形成有第一定位销孔，左、右两中架纵梁的底面上均设置至少一摩擦块，摩擦块左右对称；后架，所述后架包括左、右两后架纵梁以及在左、右两后架纵梁间的容置空间，所述中架可缩入后架的容置空间中，后架的左、右两后架纵梁的侧面上均形成有多个与第一定位销孔相对应的第二定位销孔；定位装置，其可伸缩地穿设于相对应的第一定位销孔和第二定位销孔中以将中架与后架固定于预定伸缩位置。其具有车架伸缩顺畅、操作安全方便等优点。
摘要（英）：

The utility model relates to a telescopic type semi-trailer, comprising a telescopic type vehicle frame and a travel mechanism installed under the vehicle frame. The vehicle frame comprises a front frame, a middle frame, a back frame and a positioning device. The front end of the middle frame is connected with the back end of the front frame. The middle frame comprises a left and right middle frame stringers. A plurality of first positioning pin holes are formed at the both sides at the back ends of the left and the right middle frame stringers. At least one friction block is arranged on the bottom surfaces of the left and the right middle frame stringers. The friction blocks are symmetric left to right. The back frame comprises a left back frame stringer, a right back frame stringer and a containing space between the left and the right back frame stringers. The middle frame can shrink into the containing space of the back frame. A plurality of second positioning pin holes which are corresponding to the first positioning pin holes are formed on the lateral surfaces of the left and the right back frame stringers. The positioning device can be telescopically penetrated the corresponding first positioning pin holes and the second positioning pin holes to fix the middle frame and the back frame at pre-telescopic positions. The telescopic type semi-trailer has the advantages that the vehicle frame is flexible to be telescopic, and is safe and convenient to be operated.
