a pin shaft device for fastening a small chain sprocket of a cooling bed is arranged on a chain plate of a small chain sprocket arm of the cooling bed and comprises a pin shaft head I, a pin shaft body, a pin shaft head II and a steel plate, wherein the pin shaft head I, the pin shaft body and the pin shaft head II are sequentially arranged and are of an integrated structure; the steel plate is a rectangular plate, a hole is formed in the middle of the steel plate, the hole is matched with the second pin shaft head, and the steel plate is fixedly connected with the second pin shaft head; the chain plate is arranged on the pin shaft body, the steel plate is provided with a fastening bolt hole, the steel plate is fastened on the chain plate through a bolt, and the first pin shaft head is provided with a chain wheel.

The number of the fastening bolt holes is four, the four fastening bolt holes are respectively arranged at four corners of the steel plate, and the circle centers of the four fastening bolt holes are located on the same circumference.

The first pin shaft head, the second pin shaft body and the second pin shaft head are all cylindrical, and the diameter of the first pin shaft body is larger than that of the second pin shaft head.

And a bearing is arranged between the first pin shaft head and the chain wheel.

And the steel plate is welded on the second shaft head of the pin shaft.

The utility model has the advantages that: the length of the shaft head is increased while the steel plate is increased, the size of a welding spot is increased, the vibration resistance of the small chain sprocket is enhanced, the service life of the sprocket pin shaft is prolonged, the maintenance frequency and time of the small chain of the cooling bed are reduced, the yield of steel is further improved, the production efficiency is improved, and the production cost is saved. The device has the characteristics of simple installation, low cost, simple and convenient maintenance and operation, high safety and the like.
