Problems solved by technology
[0003] This kind of forklift has the following disadvantages: since the mast is in the front and the driver is behind, most components, lifting cylinders and chain pulley blocks that make up the mast system will affect the driver's sight and make the driver's vision smaller
However, this kind of forklift has complex structure, high cost, and its own weight is heavier than that of the same tonnage gantry forklift. At present, this kind of forklift is only used for small and medium tonnage
[0006] So far, among the forklift lifting mechanisms at home and abroad, we have not found a lifting mechanism that can fundamentally improve the driver's vision, reduce the weight of the forklift, and reduce energy consumption

A spatial multi-connecting bar forktruck lift guide mechanism comprises a frame or a body, a first and a second fixed supporting blocks, a first and a second rotor arms, a first and a second telescopic booms, a fork frame and a pallet fork arranged on the fork frame; wherein the fixed supporting block is fixedly connected with the frame or the two sides of the body by welding, the rotor arm is connected with corresponding supporting block by a rotor pair, and the telescopic boom is connected with corresponding rotor arm by a sliding pair; the cross beam of the fork frame is provided with two lifting lugs which are connected with corresponding telescopic boom by the rotor pair and the sliding pair respectively and are connected with the frame or body by kinematic chains ABC and FED respectively, wherein the two kinematic chains are plane RPR kinematic chains; the axes of the rotor pair A and the rotor pair C of the kinematic chain ABC are vertical to the vertical plane where the connecting bars AB and BC are located, the axes of the rotor pair F and the rotor pair D of the kinematic chain FED are vertical to the vertical plane where the connecting bars FE and ED are located, and thetwo vertical planes is not coplanar or parallel. The invention has simple structure and convenient application and can be applied to a plurality of mechanical structures which are in fixed translational movement.
Description
technical field [0001] The invention relates to a lifting and guiding mechanism system for a forklift, in particular to a lifting and guiding mechanism for a space multi-link forklift, belonging to the field of hoisting and transporting machinery. Background technique [0002] Counterbalanced forklifts are the most common structural type of forklifts. The fork of this kind of forklift protrudes beyond the centerline of the front wheel. In order to balance the overturning moment generated by the weight of the cargo and maintain the longitudinal stability of the forklift, a balance weight is added to the rear of the car body. The working device of the forklift includes a fork, a fork frame, a chain, and a door frame, which are located in front of the forklift. The mast includes an inner mast and an outer mast, which is a telescopic structure, which can not only ensure the required lifting height, but also reduce the overall height of the forklift truck. The outer mast is hin...
