Abstract
A front-jacking hydraulic oil cylinder for a dumper is characterized in that one end of a cylinder barrel is provided with a lower hinge shaft, one end of an outer sleeve is provided with an upper hinge shaft, two ends of the cylinder barrel and two ends of the outer sleeve are respectively closed and opened, the opened end of the cylinder barrel is inserted into the opened end of the outer sleeve, and an oil inlet-output port is arranged on the cylinder barrel between the upper hinge shaft and the lower hinge shaft. By means of the arrangement, the front-jacking hydraulic oil cylinder for the dumper overcomes the disadvantages that an existing traditional belly-jacking hydraulic oil cylinder for the dumper is complicated in structure, the closing height of a cargo van base plate and a main vehicle frame is slightly large, the gravity center is slightly high, and a finished vehicle is poor in stability.
Description
Technical field
The utility model relates to a kind of hydraulic telescopic device, is a kind of dumping car sinciput formula hydraulic ram specifically.
Background technology
Dumping car is complicated with abdomen topped hydraulic cylinder structure at present, the closed height of loading space base plate and main car frame is bigger than normal, center of gravity is higher, whole vehicle stability is bad, oil cylinder is used in loading space bottom midway location, system pressure is higher, causes fault ratio of hydraulic pressure system higher, has in use caused great user's complaint.
The utility model content
The purpose of this utility model is the dumping car sinciput formula hydraulic ram that provides a kind of simple in structure, more safe and reliable.
For achieving the above object, the utility model is provided with down hinge at an end of cylinder barrel, end at outer sleeve is provided with hinge, the two ends of described cylinder barrel and outer sleeve are that an end seals an end opening, the open end of cylinder barrel inserts the open end of outer sleeve, and the cylinder barrel between upper hinge and down hinge is provided with oil inlet and outlet.
By above setting, the utility model is installed between subframe front end and the loading space, and dumping car traditional before having avoided is complicated with abdomen topped hydraulic cylinder structure, and the closed height of loading space base plate and main car frame is bigger than normal, and center of gravity is higher, the drawback that whole vehicle stability is bad.
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, outer sleeve, 4, upper hinge, 5, oil inlet and outlet.
The specific embodiment
As shown in Figure 1, the utility model is provided with down hinge 2 at an end of cylinder barrel 1, end at outer sleeve 3 is provided with hinge 4, the two ends of described cylinder barrel 1 and outer sleeve 3 are that an end seals an end opening, the open end of cylinder barrel 1 inserts the open end of outer sleeve 3, and the cylinder barrel 1 between upper hinge 4 and down hinge 2 is provided with oil inlet and outlet 5.By above setting, the utility model is installed between the subframe front end and loading space of dumping car by down hinge 2 and upper hinge 4, oil inlet and outlet 5 is connected with hydraulic efficiency pressure system, and cylinder barrel 1 can be at outer sleeve 3 interior free-extensions.
Claims (1)
