Fork laterally-moving distance-adjusting device of fork truck and special-purpose fork frame assembly

Abstract

The invention discloses a fork laterally-moving distance-adjusting device of a fork truck and a special-purpose fork frame assembly. The fork laterally-moving distance-adjusting device of the fork truck comprises a front oil supply pipeline and a function switching pipeline. By applying the two pipelines in a combined way, a plurality of motion processes can be generated. By matching with the fork frame assembly comprising a roller mechanism for application, the fork laterally-moving distance-adjusting device can achieve the fork laterally-moving function and the fork distance-adjusting function. Furthermore, the device can achieve lateral movement of a single fork and then achieve distance adjustment through the lateral movement of the single fork. The device further achieves the positioning function of a fork in a fork frame.

Description

technical field [0001] The invention relates to a cargo fork frame assembly with the function of side shifting and distance adjustment, in particular to a cargo fork side shifting distance adjustment device which cooperates with the cargo fork frame assembly to realize the function of side shifting and distance adjustment. Background technique [0002] The fork of the forklift has a distance adjustment function, but the existing fork distance adjustment function is limited to the separation or closing of the forks. The Chinese patent disclosed on August 4th, 1999, the patent name is the special distance adjustment device for the new forklift fork, and the authorized notification number is that CN2331651Y discloses a kind of distance adjustment device for controlling the closing and separation of the forks. The device includes at least two forks, and a hydraulic circuit for pushing the forks. The two forks are movably mounted on the fork assembly and are controlled by two oi...

Problems solved by technology

In order to reduce the friction consumption of key parts, only expensive high-specification materials can be used, which greatly increases the production cost

The slipping shaft sleeve is always closely connected with the bearing, causing the wear part of the shaft sleeve to be hidden. It is difficult to find the wear from the outside. Once destructive damage occurs, it cannot be found at the first time. Therefore, the fork frame assembly exists The disadvantages of poor mechanical structure stability and inconvenient maintenance
