Universal guide rod type hydraulic side-shift distance-adjusting fork used for forklift

Abstract

The invention discloses a universal guide rod type hydraulic side-shift distance-adjusting fork used for a forklift. The universal guide rod type hydraulic side-shift distance-adjusting fork used for the forklift comprises shift fork assemblies, a distance-adjusting oil cylinder, a support rod, a cross joint and a side shifter. The support rod is installed in the middle inside the side shifter. The distance-adjusting oil cylinder is installed on the support rod. The distance-adjusting oil cylinder comprises hydraulic oil cylinders, a connecting sleeve assembly, a connector and an oil passage pipeline. The two hydraulic oil cylinders are fixed on the support rod through the connecting sleeve assembly. The shift fork assemblies are fixed to the front sides of piston rod ends of the two hydraulic oil cylinders respectively. The support rod is sleeved with the two shift fork assemblies in a sliding mode. Throttle valves integrated with the ends of the two hydraulic oil cylinders are both arranged on the connecting sleeve assembly. Connectors, externally connected with a forklift oil passage, on the oil passage pipeline are fixed above the side shifter through the cross joint and bolts. The cross joint and the distance-adjusting oil cylinder are connected with the oil passage through the oil passage pipeline and the corresponding connectors. The universal guide rod type hydraulic side-shift distance-adjusting fork used for the forklift is convenient to install and detach, high in universality, safe, firm and attractive.

Description

technical field [0001] The invention relates to the technical field of special attachments for forklifts, in particular to a universal guide rod type hydraulic side shifting distance adjusting fork for forklifts. Background technique [0002] A forklift is a versatile, flexible and efficient material handling equipment. Usually, a forklift is equipped with a pair of forks as standard, which is mainly used to hold and bear the goods placed on the pallet through the fork, and then lift and tilt the forklift itself. In this process, due to the different structural forms of the pallets that bear the goods, the position of the fork placed on the forklift rack of the forklift needs to be adjusted frequently. Therefore, the forklift A double-acting side shifter cylinder is commonly used to realize the left and right movement of the side shifting and distance adjusting forks. [0003] However, the existing hydraulic side-shift distance-adjusting forks still have the following defic...

AI Technical Summary

Problems solved by technology

[0003] However, the existing hydraulic side-shift distance-adjusting forks still have the following deficiencies: 1. The position of the joint of the oil circuit of the external forklift is concealed, which is inconvenient to disassemble and assemble the oil pipe, and cannot be used for various forklifts; The throttle valve is located at the end of the oil cylinder, and the installation is scattered, and the safety and firmness are poor; 3. Most of the oil pipelines are exposed on the sideshifter frame, which is not fixed firmly, and it is easy to be damaged by collision and affect the appearance when loading; 4. The support rod and the hydraulic cylinder are fixed by traditional welding process, the process is complex and inconvenient to disassemble
