Abstract

The invention provides a telescopic cylinder guide rail in automobile crane. The telescopic cylinder guide rail includes two guide rail bodies which are fixedly disposed on a cylinder and are arranged in parallel with an axis of the cylinder. The two guide rail bodies are respectively arranged at the two sides of the cylinder in a mirror symmetrical manner. Each guide rail body is similar to a C-shaped structure. A self-lubricating guide plate is arranged on an external surface of each guide rail body. The telescopic cylinder guide rail is advantaged in that according to the technical scheme, a C-shaped metal plate structure is not only light in weight but also low in processing difficulty, is small in required occupied area of machine tools, is low in cost and is good in strength. The telescopic cylinder guide rail is simple in structure, is convenient to repair and is easy to product.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a telescopic oil cylinder guide rail of a car crane. Background technique [0002] The prior art telescopic oil cylinder guide rails of automobile cranes generally adopt a casting structure.
