Abstract
The utility model provides a telescopic oil cylinder guide rail of a truck-mounted crane, which comprises guide rail bodies, wherein the guide rail bodies are fixedly arranged on an oil cylinder; the guide rail bodies are parallel to the axis of the oil cylinder; two guide rail bodies are provided and are arranged on the two sides of the oil cylinder in mirror symmetry; each guide rail body is in a similar C-shaped type; and a self-lubricating guide plate is arranged on the outer surface of each guide rail body. The guide rail provided by the utility model has the beneficial effects that by adopting the technical scheme, the C-shaped metal plate structure is light with little difficulty in processing; and moreover, by adopting a machine tool, the guide rail occupies small space and has low cost and good strength. The guide rail provided by the utility model has the advantages of simple structure, convenience in maintenance, easiness in production and the like.
Description
Technical field
The utility model belongs to engineering machinery field, especially relates to a kind of wheel crane telescopic oil cylinder guide rail.
Background technology
The wheel crane telescopic oil cylinder guide rail of prior art generally adopts casting structure, although this casting structure intensity ratio is better, have following shortcoming: weight is very heavy, cost is high, and difficulty of processing is large, and the lathe volume of use is large, take the factory building space large, the corresponding increase of whole investment.
Summary of the invention
It is low that problem to be solved in the utility model is to provide a kind of difficulty of processing, and lightweight telescopic oil cylinder guide rail especially is suitable for wheel crane.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of wheel crane telescopic oil cylinder guide rail, comprise guide rail body, described guide rail body is fixedly installed on described oil cylinder, the axis of described guide rail body and described oil cylinder be arranged in parallel, and the number of described guide rail body is two, and mirror image is located at the both sides of described oil cylinder symmetrically, described guide rail body is class C font, and the outside face of described guide rail body is provided with self-lubricating guide plate.
Described guide rail body is the sheet metal structural that is bent into class C font.
The end face of described guide rail body and the dimension limit of bottom surface are less than or equal to 0.05mm, and the dimension limit of the side of described guide rail body is less than or equal to 0.1mm.
Described guide rail body is provided with the connecting panel that is connected with described oil cylinder.
Advantage and the good effect that the utlity model has are: due to the employing technique scheme, and the sheet metal structural of C font, not only lightweight, difficulty of processing is little, and it is little to use lathe to take up room, and cost is low, and intensity is good; The utlity model has the advantages such as simple in structure, easy to maintenance, easy production.
