A forklift mast with buffer structure

Abstract

The invention relates to the technical field of forklifts, in particular to a forklift mast with a buffer structure, including an outer mast, an inner mast, a fork frame, a hydraulic cylinder, an oil pump, and a buffer structure. The buffer structure includes a flow divider and an accumulator. and an energy release device, the diverter is arranged on the top of the outer mast and the inner mast, the diverter includes a trigger part, the diverter also includes an oil inlet, an oil outlet and an oil distribution port, the oil inlet and the oil pump The oil outlet is connected with a communication port of the hydraulic cylinder; the accumulator includes an energy storage part, which is connected with the oil distribution port, and the accumulator also includes a conduction part that can move relative to the outside under the state of energy storage; the release The energy device is arranged on one side of the accumulator, and the energy release device includes a driving part. The flow divider in the buffer structure of the present application divides the hydraulic oil between the oil pump and the hydraulic cylinder, and stores it in the accumulator without Increase the load of the oil pump, and the structure is stable and easy to install.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a forklift mast with a buffer structure. Background technique [0002] The lifting system used by the forklift includes the forklift mast. When the forklift mast is lifted to the top, that is, after the oil cylinder travels, it will cause a large impact due to inertia and heavy objects, which will cause vibration of the whole vehicle, resulting in The driver is uncomfortable; in addition, the impact also affects the safety and stability of the cargo. [0003] At present, few forklift lifting systems have an upper buffer mechanism when the mast is lifted to the top, and only a few realize the buffer function through the lifting cylinder. Specifically, the throttling technology is used inside the cylinder, which has a complex structure, difficult processing, and high cost. , Once the oil cylinder has a problem, the buffer will also lose its effect, so it is not reliable.

AI Technical Summary

Problems solved by technology

[0005] The buffer device reduces the flow rate of the hydraulic oil by reducing the diameter of the pipeline through which the hydraulic oil flows, resulting in a decrease in the output speed of the hydraulic cylinder. However, the flow rate of the hydraulic oil will increase, resulting in little change in the flow rate of the hydraulic oil. The purpose of reducing the output speed of the hydraulic cylinder will also cause a large load to the oil pump, which will affect the stable operation and life of the oil pump, and will cause the temperature of the hydraulic oil at the narrow diameter to rise
