Description

Nodular cast iron pipe buffer stop Technical Field The utility model relates to the technical field of cast tube production, in particular to a nodular cast iron tube anti-collision device. Background All the current cast tube industries generally stack cast tubes on rails for transfer or storage throughout the production, transfer and storage processes. Along with the development strategy of environmental protection and energy saving, the existing cast tube is developed towards the light and thin direction under the condition of ensuring the service life, so that the damage risk caused by collision between the cast tube with the thin tube wall and the rail is directly increased, and particularly, the cast tube is arranged at the end part of the rail. In order to avoid the cast tube from falling from the end of the rail, serious potential safety hazards are caused, the existing setting mode is to weld a wedge iron at the tail end of the rail to block and limit the tube body at the end of the rail so as to prevent falling, but when the cast tube is contacted with the wedge iron, the thin tube wall or the outer coating of the tube wall is generally damaged due to hard collision, so that the product quality of the cast tube is reduced. In view of the above drawbacks, the present inventors have finally achieved the present utility model through long-time studies and practices. Disclosure of utility model In order to solve the technical defects, the utility model adopts the technical scheme that the nodular cast iron pipe anti-collision device comprises a connecting seat and a buffer wheel, wherein the connecting seat is fixedly arranged at the end part of a track, the buffer wheel is arranged into a cylinder, a rotating hole is formed in the axis of the buffer wheel, a rotating shaft is arranged in the rotating hole, and the rotating shaft is fixedly arranged on the connecting seat. Preferably, the connecting seat comprises two side plates and a bottom plate, the bottom plate is fixed at the bottom of the track, the two side plates are symmetrically and vertically fixed at two ends of the bottom plate, the two side plates are fixed at two sides of the track, and the upper end face of each side plate does not exceed the upper edge face of the track. Preferably, the side plates are far away from the end parts of the tracks, connecting plates are provided with connecting holes, two ends of the rotating shaft are respectively arranged in the connecting holes of the two side plates, and the axis of the connecting holes exceeds the upper edge surface of the tracks.
