Forklift door frame and forklift

Abstract

The invention relates to a forklift door frame, and provides a forklift door frame and a forklift in order to solve the problems that an existing forklift door frame is high in roller cost and difficult to maintain. The forklift door frame comprises an inner side door frame body and an outer side door frame body, wherein the outer side door frame body comprises outer side stand columns; and the inner side door frame body comprises inner side stand columns. The forklift door frame is characterized by further comprising sliding blocks arranged between the adjacent outer side stand columns and inner side stand columns; the sliding blocks are fixed to the side face of one of the adjacent outer side stand column and inner side stand columns and provided with sliding friction working faces making contact with the side face of the other stand columns in an attached mode; a plurality of communicated grease storage grooves are formed in the sliding friction working faces of the sliding blocks;grease storage oil channels are formed in the sliding blocks; and lubricating grease filling ports communicated with the grease storage oil channels are formed in the tops of the sliding blocks. According to the forklift door frame and the forklift, rollers in a traditional door frame are replaced with the sliding block structures, the limiting structure of the inner side door frame body is simplified, the manufacturing cost is reduced, and meanwhile the maintenance convenience is improved.

Description

technical field [0001] The invention relates to a forklift mast structure, more specifically, to a forklift mast and a forklift. Background technique [0002] The existing forklift mast includes an inner mast and an outer mast. The outer mast includes two column channel steels. A roller assembly is installed on the top of the column channel steel facing the inner side of the inner mast. The roller assembly includes lateral rollers and main Roller, the roller is installed on the roller shaft, the roller shaft of the main roller is usually welded on the channel steel of the column, and the wheel shaft of the side roller is installed on the channel steel of the column through bolts and nuts. [0003] The existing forklift mast of the above structure mainly has the following disadvantages: [0004] 1. The manufacturing cost is high. Firstly, the cost of the rollers and axles involved is relatively high, and secondly, drilling, welding, and even cutting are required during inst...
