Safety rack machining method and safety rack structure

Abstract

The invention relates to a safety rack machining method and a safety rack structure. The safety rack structure comprises at least one safety rack which is mounted on guiding columns of the two sides of a lifting machine; each safety rack is a long-strip-shaped body which is made of a metal material with a certain wall thickness and of which the three sides are surrounded and one side is open; a plurality of safety teeth which are the same in tooth direction are disposed on a working surface of the long-strip-shaped body to form a hollow straight rack; each safety tooth comprises a horizontal bearing portion, a reinforced straight plate portion and an inclined sliding portion, wherein working surfaces of the horizontal bearing portion and the inclined sliding portion are sections with thickwalls. The product is formed through the machining method of forming a trapezoidal hole in a steel plate in a stamping mode and performing bending to form the safety teeth, machining is simple, convenient and rapid, the machining efficiency is improved, meanwhile the manufacturing material is saved, and the production cost is reduced. The structure is simple and reliable, and assembling and disassembling are flexible and convenient.

Description

technical field [0001] The invention relates to the field of lifting equipment machinery, in particular to a processing method and structure of a safety gear rack of a lift. Background technique [0002] The structure of the existing car lift mainly includes a column, a motor, a control device and a lifting mechanism. The column is provided with a safety rack. There are usually two types of processing for the safety rack, one is single tooth processing and then assembled, and the other is The second is to use a milling cutter to process tooth by tooth on a solid steel bar. These two processing structures are slow, inefficient, and waste metal materials. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and deficiencies, to provide a processing method and structure of a safe safety gear rack of a lift that is convenient, fast, and material-saving. [0004] The technical scheme of the processing method of the safe...

[0002] The structure of the existing car lift mainly includes a column, a motor, a control device and a lifting mechanism. The column is provided with a safety rack. There are usually two types of processing for the safety rack, one is single tooth processing and then assembled, and the other is The second is to use a milling cutter to process one tooth at a time on a solid steel bar. These two processing structures are slow, inefficient, and waste metal materials.
