Abstract
The utility model discloses a simple former top type hydraulic oil cylinder for a dump truck, which is characterized in that a lower hinged shaft is arranged at one end of a cylinder barrel; one end of the cylinder barrel is sealed, and the other end of the cylinder barrel is open; a plunger piston is arranged at the open end of the cylinder barrel; a connecting ring is arranged at one end of the plunger piston; and an oil inlet and outlet hole is formed in the outer wall of the cylinder barrel. Through the arrangement, the simple former top type hydraulic oil cylinder overcomes the defects of the existing simple former top type hydraulic oil cylinder for the dump truck and is suitable for the development trend that the dump truck is lightened.
Description
Technical field
The utility model relates to a kind of hydraulic telescopic device, is a kind of dumping car specifically with simple and easy sinciput formula hydraulic jack.
Background technique
Present dumping car is down hinge with sinciput formula hydraulic jack and is connected with subframe, and upper hinge is connected with loading space, and upper hinge is arranged on the outer sleeve, this set complex structure, cost is higher, and oil cylinder weight lays particular stress on, and is not suitable with dumping car to the trend of " lightweight " development.
Summary of the invention
The purpose of this utility model is the dumping car that more can adapt to existing dumping car development trend with simple and easy sinciput formula hydraulic jack.
For achieving the above object, the utility model is provided with down hinge at an end of cylinder barrel, and the two ends of described cylinder barrel are that an end seals an end opening, is provided with plunger at the opening end of cylinder barrel, and connecting ring is located at an end of plunger, is provided with oil inlet and outlet at the outer wall of cylinder barrel.
By above setting, the utility model is installed in the subframe front end is connected with the loading space bearing pin, traditional dumping car defective of sinciput formula hydraulic jack is fit to dumping car to the trend of " lightweight " development before having avoided.
Description of drawings
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, cylinder barrel, 2, down hinge, 3, plunger, 4, connecting ring, 5, oil inlet and outlet.
Embodiment
As shown in Figure 1, the utility model is provided with down hinge 2 at an end of cylinder barrel 1, and the two ends of described cylinder barrel 1 are that an end seals an end opening, is provided with plunger 3 at the opening end of cylinder barrel 1, and connecting ring 4 is located at an end of plunger 3, is provided with oil inlet and outlet 5 at the outer wall of cylinder barrel 1.By above setting, the utility model is installed in the subframe front end by down hinge 2, and connecting ring 4 is connected with the loading space bearing pin, and oil inlet and outlet 5 is connected with hydraulic system, and plunger 3 can be at cylinder barrel 1 interior free-extension.
