Problems solved by technology

[0003] At present, in the long-term rigid interaction between the existing guide roller group and the mast, the channel steel of the mast and the rollers are very worn; in addition, the rollers cannot be adjusted, because the mast is a multi-stage mast, so the After the frame works for a long time, such as the channel steel inner webs and rollers of all levels of the door frame will be seriously worn. It is a very heavy work for the maintenance personnel to replace and wait for incoming parts.

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The guide roller set cooperates with each other through the main roller piece 3, the side roller piece 4 and the adjustment assembly 5, so that the whole guide roller set has a simple structure, a reasonable layout, and is easy to install and disassemble. The inner sides of the two side plates of the channel steel 1 roll, and the side rollers 4 roll along the inner side of the middle plate of the inner channel steel 1 of the mast, so that the entire guid...

Abstract

The invention discloses a guiding idler wheel set of a fork multistage gantry. The guiding idler wheel set is arranged between gantry inner channel steel and gantry outer channel steel and comprises amain idler wheel piece, a lateral idler wheel piece and an adjusting assembly, wherein the main idler wheel piece and the lateral idler wheel piece move up and down along the gantry inner channel steel, and one end of the adjusting assembly and the gantry outer channel steel are fixedly mounted. A lateral idler wheel seat and the adjusting assembly are connected through a thread. According to theguiding idler wheel set of the fork multistage gantry, annular abrasion-resistant rings are embedded into the outer circumferential faces of a main idler wheel and a lateral idler wheel, so that whenthe guiding idler wheel set is used, the abrasion-resistant ring of the main idler wheel makes contact with the inner side faces of two edge plates of the gantry inner channel steel, the abrasion-resistant ring of the lateral idler wheel makes contact with the inner side face of a middle plate of the gantry inner channel steel, the situation that the main idler wheel and the lateral idler wheel directly make contact with the gantry inner channel steel is avoided, thus the abrasion degree to the gantry channel steel and abrasion of the main idler wheel and the lateral idler wheel are reduced,and the service life of the guiding idler wheel set and the gantry channel steel is prolonged.

Description

technical field [0001] The invention relates to the technical field of forklift masts, in particular to a set of guide rollers for a multi-stage mast of a forklift. Background technique [0002] The support and guide mechanism of the forklift mast is an important part of the lifting system. For example, the four-stage mast of the forklift is mainly composed of channel steel for the outer mast, channel steel for the first-stage mast, channel steel for the second-stage mast, and inner door. Frame channel steel, carriage, main rollers, and side rollers, which are respectively guided by the corresponding gantry channel steel and corresponding main rollers and side rollers, so as to ensure that the load moves vertically and linearly with the gantry, and at the same time It must be able to reliably withstand the moments in two directions of forward tilt and sideways movement caused by the lifted load. [0003] At present, in the long-term rigid interaction between the existing gu...
