Abstract
The utility model provides a combined type hydraulic cylinder which comprises a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder is connected with the second hydraulic cylinder side by side in opposite mode, a welding block is installed between the first hydraulic cylinder and the second hydraulic cylinder, and the first hydraulic cylinder and the second hydraulic cylinder are welded through the welding block. According to the combined type hydraulic cylinder, the first hydraulic cylinder and the second hydraulic cylinder are welded with each other through the welding block, intensity is high, and the first hydraulic cylinder and the second hydraulic cylinder are not easy to loose because of rigid connection.
Description
Technical field:
The utility model relates to a kind of combination hydraulic oil cylinder that is used in the ladder truck elongated boom.
Background technique:
The engineering machinery of band extending means is provided with oil hydraulic cylinder usually; Be used to control and drive the stretching, extension and the withdrawal of extending means; Especially for the oil hydraulic cylinder in the ladder truck elongated boom, the length of common oil hydraulic cylinder can be bigger, and mounting distance also can be longer; But flexible stroke is shorter, is inappropriate for and stretches the bigger installation requirement of span.
Therefore; Occur a kind of combined type hydraulic cylinder at present, it comprises first oil hydraulic cylinder, second oil hydraulic cylinder, and these two oil hydraulic cylinders are installed side by side and be reverse each other; But be connected with bolt through connecting plate between first oil hydraulic cylinder of the prior art and second oil hydraulic cylinder; This Placement adopts part more, and mechanical strength is lower, and two oil hydraulic cylinders interconnect loosening easily.
The model utility content:
The main purpose of the utility model is, overcomes existing technological deficiency, provides that a kind of mechanical strength is high, interconnects between two oil hydraulic cylinders and be difficult for loosening combined type hydraulic cylinder.
The technological scheme that the utility model provides is: the utility model provides a kind of combined type hydraulic cylinder; It comprises first oil hydraulic cylinder, second oil hydraulic cylinder; Said first oil hydraulic cylinder is connected with second oil hydraulic cylinder and oppositely side by side; Be provided with welding block between said first oil hydraulic cylinder and second oil hydraulic cylinder, said first oil hydraulic cylinder and second oil hydraulic cylinder are through the welding block welding.
Adopt said structure, the utlity model has following advantage:
First oil hydraulic cylinder and second oil hydraulic cylinder adopt welding block to be welded to each other in the utility model combined type hydraulic cylinder; Intensity is high; Being rigidly connected between first oil hydraulic cylinder and second oil hydraulic cylinder is difficult for loosening; Particularly, require can not become flexible each other between first oil hydraulic cylinder and second oil hydraulic cylinder in the ladder truck elongated boom, otherwise dangerous high.
Also be provided with the stiffening rib that props up welding block on the outer side wall of said first oil hydraulic cylinder or second oil hydraulic cylinder.Said stiffening rib props up welding block and strengthens weld strength, prevents that first oil hydraulic cylinder and second oil hydraulic cylinder from breakking away each other.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model combined type hydraulic cylinder;
As shown in the figure: 1, first oil hydraulic cylinder, 2, second oil hydraulic cylinder, 3, welding block, 4, stiffening rib, 5, pipeline.
Embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated:
As shown in the figure: the utility model provides a kind of combined type hydraulic cylinder; It comprises first oil hydraulic cylinder 1, second oil hydraulic cylinder 2; Said first oil hydraulic cylinder 1 is connected side by side with second oil hydraulic cylinder 2 and is reverse; The i.e. parallel axes of first oil hydraulic cylinder 1 and second oil hydraulic cylinder 2, and piston rod flexible in the opposite direction, so the stroke of this combined type hydraulic cylinder is the stroke that the stroke of first oil hydraulic cylinder 1 adds second oil hydraulic cylinder 2.Be provided with welding block 3 between said first oil hydraulic cylinder 1 and second oil hydraulic cylinder 2, said first oil hydraulic cylinder 1 and second oil hydraulic cylinder 2 are through welding block 3 welding.Welding block 3 is two in the present embodiment, is separately positioned on the two ends (only illustrating among the figure) of the joint of two oil hydraulic cylinders.First oil hydraulic cylinder 1 and second oil hydraulic cylinder 2 are communicated with through pipeline 5.
Also be provided with the stiffening rib 4 that props up welding block 3 on the outer side wall of said first oil hydraulic cylinder 1 or second oil hydraulic cylinder 2.Stiffening rib 4 is arranged on the outer side wall of second oil hydraulic cylinder 2 in the present embodiment, and offsets with welding block 3.
Claims (2)
