Abstract

The invention discloses a frame lifting and linking device for a manual carrier. The frame lifting and linking device comprises a supporting base, a frame and a linking device body, wherein the frame is mainly composed of a fork, fork wheels, a front plate and a top plate. The fork wheels are arranged at the front end of the fork. A front plate is fixedly arranged between the fork and the top plate. A rotating pivot is arranged on the front plate. The linking device body connecting the supporting base and the frame comprises a connecting rod assembly. The pivot is sleeved with a cradle. The cradle is provided with a swing arm and a swing block. The swing arm is connected to the supporting base. A coupling head at one end of the connecting rod assembly is connected to a support plate of the fork wheels through a conversion block. A coupling head at the other end of the connecting rod assembly is connected to the swing block through a chain. The chain is meshed with an incomplete chain wheel which is fixed to the bottom end of the front plate. The stress manner of the connecting rod assembly is changed, deformation of the connecting rod assembly is reduced, and the service cycle of the whole carrier is prolonged.

Description

technical field [0001] The invention relates to a device for carrying heavy objects, in particular to a linkage device for lifting and lowering a vehicle frame in a manual transport vehicle. Background technique [0002] When handling heavy bulk goods, it is generally done with the help of mechanical loading tools, usually using forklifts. The manual hydraulic forklift in the forklift is widely used. This kind of forklift uses hydraulic pressure to lift the goods and carry the goods to move through the wheels. A manual hydraulic pallet truck is commonly used in existing manual hydraulic forklifts. The structure of this manual hydraulic pallet truck mainly includes a handle, a frame, a support seat, a hydraulic cylinder arranged on the support seat, and a piston rod connected to the hydraulic cylinder. The upper end is connected to the top plate of the frame, and the lifting of the frame needs to be driven by a hydraulic cylinder. The fork of the frame is used as a load pla...
