Abstract

The invention discloses a mast correction device comprising a base (1). A pair of sliding rails (2) holding a mast are arranged on the base (1) symmetrically. The mast correction device is characterized in that a middle support (3) is movably arranged between the sliding rails (2); a two-way rod-extending hydraulic oil cylinder (4) is arranged on the middle support (3); the outer sides of the sliding rails (2) are each provided with a side edge support (5) movably; and each side edge support (5) is provided with a hydraulic oil cylinder (6).

Description

technical field [0001] The invention relates to an online correction device for the opening size of a mast, in particular to an online correction device for the opening size of a forklift mast. Background technique [0002] During the production process of the mast, if the opening size of the mast is out of tolerance, it is completely corrected by the help of ordinary jacks and corresponding tools. Low efficiency and high labor intensity. Based on the above reasons, the on-line correction device for the opening size of the mast is designed, and the combination of movable and different structure oil cylinders is used to complete the correction of the out-of-tolerance of the partial opening size of the mast on the production line. Contents of the invention [0003] In order to solve the deficiencies in the prior art, an online and pass-through gantry correction device with simple structure, convenient operation, low labor intensity and high processing efficiency is provided...
