Description

Cross-country fork truck fork quick distance adjusting device Technical Field The utility model relates to the technical field of forklifts, in particular to a quick distance adjusting device for a fork of an off-road forklift. Background The utility model discloses a fork distance-adjusting device for fork truck, which is provided with a long shaft horizontally arranged at the front end of a fork frame assembly of the fork distance-adjusting mechanism, two forks are movably sleeved on the long shaft, a chain transmission mechanism which can move the two forks towards opposite directions or opposite directions when any fork is pushed by external force is arranged between the two forks and the fork frame assembly, and a distance-adjusting oil cylinder for pushing any fork is arranged on the fork frame assembly. When one fork is controlled to move under the drive of hydraulic oil, the chain drives the other fork to synchronously move in opposite directions, so that the aim of simultaneously controlling two forks by the one distance-adjusting oil cylinder is fulfilled, synchronous distance adjustment of the forks can be realized, and meanwhile, the manufacturing cost of the fork truck distance-adjusting fork is reduced due to the reduction of one oil way and a control valve. The fork distance adjusting device adopts a driving mechanism formed by an oil cylinder, a chain wheel and a chain to drive two forks to synchronously and relatively move, but the fork distance adjusting device cannot independently adjust the position of a single fork, so that the flexibility is poor.
