Telescopic arm provided forklift pallet fork levelling device and automatic debugging method thereof

Abstract

The invention discloses a telescopic arm provided forklift pallet fork levelling device and an automatic debugging method thereof. The pallet fork levelling device comprises a pallet fork frame and atelescopic mechanism, wherein the pallet fork frame is equipped with a pallet fork; the telescopic mechanism is used for levelling the pallet fork; the telescopic mechanism comprises a front arm, thetelescopic arm and a levelling mechanism, wherein the front arm is rotationally connected with the pallet fork frame; the tail end of the telescopic arm is rotationally connected with a forklift frame; and the levelling mechanism is used for levelling the pallet fork. By inter-coordination of all power mechanisms which are connected with the pallet fork frame and the telescopic arm, the pallet fork levelling device disclosed by the invention can realize stable, rapid and accurate levelling on the pallet fork frame which is equipped with the pallet fork, is simple in levelling operation and isgood in levelling effect; a rollover power mechanism, a variable-amplitude power mechanism and a compensation power mechanism each consist of a power oil cylinder and a telescopic push rod; all push rods can stretch and retract a plurality of times in order to push and pull the pallet fork frame or the telescopic arm to move, so the gas inside each power oil cylinder can be completely exhausted, and the working safety and stability of the pallet fork of a telescopic arm provided forklift can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of forklift forks, in particular to a telescopic arm forklift fork leveling device and an automatic debugging method thereof. Background technique [0002] The telescopic arm forklift is an organic combination of the telescopic arm structure of the truck crane and the loading and unloading function of the traditional forklift. It can continuously change the length of its telescopic arm to achieve the required working height and distance. The fork at the top of the telescopic arm is used to load goods. When the telescopic arm is in the process of luffing up and down, the fork must always be automatically kept level, which is the automatic leveling system of the fork. [0003] At present, there are mainly two kinds of leveling systems, electronic control and hydraulic, on the market. Due to the high price and high maintenance cost of the electronically controlled automatic leveling system, it is rarely used. ...

Problems solved by technology

Due to the high price and high maintenance cost of the electronically controlled automatic leveling system, it is rarely used

Fork hydraulic automatic leveling system, during installation, due to the presence of gas in the oil cylinder, the function is difficult to realize, and the exhaust through the safety valve on the oil cylinder will not only have poor exhaust effect, but also affect the performance of the safety valve, and the labor intensity will also be reduced. bigger
