Abstract
The utility model discloses a kind of assembled hydraulic oil cylinder, comprises upper cylinder, lower oil cylinder, and described upper cylinder is relative with afterbody according to head with lower oil cylinder, by positioning key and the connecting base, the clamping bolt that are welded on upper cylinder, lower oil cylinder surface, is fixed together side by side.It is short that the utility model has not only solved stroke, take up room large, installation and maintenance are inconvenient and high in cost of production problem, and the action that makes assembling machine steady and smooth more, also has easy manufacture, the easy advantage such as installation.
Description
Technical field
The utility model relates to a kind of hydraulic jack, refers to especially a kind of assembled hydraulic oil cylinder for engineering machinery.
Background technique
In engineering machinery field, the translation oil cylinder of existing assembling machine is all to adopt two single-body hydraulic cylinders to drive transmission framework to move on lifting framework, the stroke of single-body hydraulic cylinder is shorter, not only take up room large, and the expanding-contracting action of two single-body hydraulic cylinders can not reach synchronously, affected quality and the progress of engineering construction.
Model utility content
Problem to be solved in the utility model is the deficiency overcoming in background technique, a kind of assembled hydraulic oil cylinder is provided, and this assembled hydraulic oil cylinder, has not only solved stroke short, take up room large, installation and maintenance are inconvenient and high in cost of production problem, and the action that makes assembling machine steady and smooth more.
For addressing the above problem, the utility model is taked following technological scheme:
A kind of assembled hydraulic oil cylinder of the present utility model, comprises upper cylinder, lower oil cylinder, and described upper cylinder is relative with afterbody according to head with lower oil cylinder, by positioning key and the connecting base, the clamping bolt that are welded on upper cylinder, lower oil cylinder surface, is fixed together side by side.
A corrective measure of the present utility model is: the piston rod of described upper cylinder is connected with transmission frame rack by left bearing pin.
Further improvement of the utility model measure is: the piston rod of described lower oil cylinder is connected with the lifting frame rack of assembling machine by right bearing pin.
A kind of assembled hydraulic oil cylinder of the present utility model, owing to comprising upper cylinder, lower oil cylinder, described upper cylinder is relative with afterbody according to head with lower oil cylinder, by positioning key and the connecting base, the clamping bolt that are welded on upper cylinder, lower oil cylinder surface, is fixed together side by side.Therefore, it is short that the utility model has not only solved stroke, take up room large, installation and maintenance are inconvenient and high in cost of production problem, and the action that makes assembling machine steady and smooth more, also has easy manufacture, the easy advantage such as installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
