The invention provides a butt joint anti-disengaging device for a gooseneck of a scrap steel tank car. The butt joint anti-disengaging device comprises an upper base fixed to a gooseneck base and a lower base fixed to the gooseneck. The upper base is provided with a first long-strip-shaped hole which is transversely formed, the lower base is provided with a second long-strip-shaped hole which is longitudinally formed, the length of the first long-strip-shaped hole is a first preset length, and the length of the second long-strip-shaped hole is a second preset length; a bolt is inserted between the first long-strip hole and the second long-strip hole; the gooseneck and the gooseneck base are limited in the vertical direction through the first long-strip-shaped hole of the upper base, the second long-strip-shaped hole of the lower base and the plug pin, and stable connection of a tractor and a trailer is guaranteed. Due to the arrangement of the two long-strip-shaped holes, it is guaranteed that when the gooseneck and the gooseneck base are inserted in place, a plug pin can be inserted into a pin hole formed in the overlapping position of the two long-strip-shaped holes; and the situation that when the gooseneck and the gooseneck seat are not inserted in place, the two long-strip-shaped holes still have an overlapping part for the insertion of the plug pin, so that the abnormal towing of a towing vehicle and a trailer cannot be found in time is avoided.
本发明提供一种用于废钢料槽车鹅颈的对接防脱装置,包括固定于鹅颈座上的上底座以及固定于鹅颈的下底座;上底座上开设有横向布置的第一长条孔,下底座开设有纵向布置的第二长条孔,第一长条孔的长度为第一预定长度,第二长条孔的长度为第二预定长度;第一长条孔与第二长条孔之间插设有插销;通过上底座的第一长条孔、下底座的第二长条孔以及插销对鹅颈与鹅颈座的上下方向进行限定,保证牵引车与拖车的稳定连接;两个长条孔的设置既保证了鹅颈与鹅颈座插接到位时,插销能够插入两长条孔的交叠处形成的销孔;又避免了鹅颈与鹅颈座插接不到位时,两个长条孔仍存在可供插销插入的交叠处,进而导致牵引车与挂车拖挂异常无法被及时发现的情形。
