Abstract
The utility model discloses a forklift fork distance adjusting structure assembly which comprises a mounting frame, fork mounting racks and forks. Output shafts of oil cylinders on the mounting frame are fixedly connected with the corresponding fork mounting racks. Two groove type rails are oppositely arranged on an upper beam and a lower beam of the mounting frame. Rolling wheels arranged on the fork mounting racks are arranged in the groove type rails in a clamped mode so that the fork mounting racks can be located in the middle position between the upper beam and the lower beam of the mounting frame, and the fork mounting racks can move in the transverse direction relative to the mounting frame. The top end of the upper beam of the mounting frame is provided with an L-shaped grooved rail. Each fork is provided with a hook. The hooks are arranged in the L-shaped grooved rail in a lap joint mode and can slide in the L-shaped grooved rail. The transverse width of each fork mounting rack is larger than that of each fork. Limiting plates are arranged on the fork mounting racks on the two sides of the forks. The fork mounting racks drive the forks to move in the transverse direction through the limiting plates. The forklift fork distance adjusting structure assembly has the advantages of achieving synchronous distance adjustment of the two forks, ensuring that the front overhang distance of a whole forklift is small, facilitating intelligent operation of the forklift and the like.
