The invention provides a coal mine car with an extensible connecting structure, relates to the field of coal mine transportation, and solves the problems that under the action of drawing force or pushing force between two mine cars, the adjustment of the positions of pin holes is strenuous and tedious, and a locking bolt needs to be locked manually, small coal briquettes or powder slag falling onto a rail is easily adhered to a roller, so that the roller vibrates during rotation. The coal mine car with the extensible connecting structure comprises a connecting seat A, and the connecting seat Ais fixedly connected to the rear end surface of the mine car through bolts. During connection, when the two fixing screw rods are screwed by the threads and are inserted into soil, a positioning structure is formed between the two fixing screws and soil, at the moment, alignment between the connector and a rotary connecting base can be achieved by rotating the threaded rod through the threads, and therefore drawing force or pushing force between the two mine cars can be conveniently eliminated, convenience is provided for connection of the connector and the rotary connecting base, the threaded rod can be rotatably adjusted, and telescopic alignment can be achieved.
本发明提供一种带有可延伸连接结构的煤矿矿车,涉及煤矿运输领域,解决了由于受两台矿车之间拉伸力或者推动力作用下,调整销孔位置时比较费力繁琐,且闭锁插销需要手动闭锁;掉落到轨道上的小型煤块或者粉渣容易粘附在滚轮上,从而导致滚轮转动时产生振动的问题。一种带有可延伸连接结构的煤矿矿车,包括连接座A;所述连接座A通过螺栓固定连接在矿车的后端面。连接时,当螺纹拧动两根固定螺杆与扎入泥土中时,两根固定螺杆与泥土之间组成定位结构,此时螺纹转动螺纹杆可实现连接头和转动连接座之间的对正,从而可方便消除两台矿车之间的拉伸力或者推动力,为连接头和转动连接座的连接提供方便,且螺纹杆可转动调节,能够实现伸缩对正。
