The invention discloses an automatic locking device for a rail car. The automatic locking device comprises a check block which is fixed to the tail end of a rail and is used for limiting the maximum advancing displacement of the rail car, and an automatic locking mechanism adjacent to the check block, wherein the distance between the automatic locking mechanism and the check block adapts to the diameter of each wheel of the rail car; the automatic locking mechanism comprises a revolving shaft which vertically passes through the rail; an arc-shaped plate corresponding to a front wheel of the rail car is arranged on the revolving shaft; a one-way locking mechanism for limiting axial rotation of the revolving shaft is arranged at one end of the revolving shaft; a manual unlocking device is arranged on the one-way locking mechanism. By adopting the automatic locking device for the rail car, the rail car can be reliably fixed to a specific position on the rail. Moreover, the automatic locking device is simple in structure, and is convenient for manual operation.
Description
[technical field] [0001] The invention relates to a locking device, in particular to an automatic locking device for railcars. [Background technique] [0002] Rail car, also known as rail flat car, is a kind of electric transport vehicle with rails. It needs to lay tracks on the ground. The rails are generally I-shaped surface contact rails; Simple structure, easy to use, large carrying capacity, not afraid of being dirty or smashed, easy maintenance, long service life, etc., because of its convenience, economy, practicality, and easy cleaning, it has become a short-distance fixed-point frequent transportation inside the factory building and between the factory buildings. The preferred means of transport for heavy loads. However, for the rail car working in a narrow space, it is inconvenient for people and tools to interfere with its activities, which makes it difficult to reliably fix the rail car at a specific position on the track, which is not conducive to the loading a...
