Abstract

The utility model which relates to a high-dump car is provided with the various functions of the common dump car, and the carriage which can be raised is followed by the unloading. A lifting appliance is added to the original structure of the dump car, and the lifting and the lowering movements are performed according to the principle of the motion composition of the moveable operation of two oil cylinders. The utility model has the advantages that the structure is simple, the self-dumping and the loading task can be implemented at a higher position, and the utility model especially adapts to the unloading performed by the car to a railway carriage; besides, the utility model can be used in the building and the mineral place.

Description

High-Dump Wagon

The utility model relates to a kind of High-Dump Wagon that is used for lade.

In vehicle in use transportation and the lade process, handling goods occupies very big work capacity, and the appearance of dumping truck has significantly reduced the work capacity of automobile unloading, at the loading and unloading stone, in all class bulk freight such as mineral, unloading fast automatically of dumping truck shown tangible advantage.Yet with regard to present dumping truck, its height that dumps goods is all fixed, and promptly the height of goods along automotive frame itself can only be unloaded.In actual use, often need goods is discharged to the higher position that is higher than automotive frame, perhaps pile up goods higher, it self is incompetent that this dumping truck for present this fixed type height only depends on.

The purpose of this utility model is to provide a kind of High-Dump Wagon, and it not only has the common various functions that dumping truck possessed, and can also in the certain height scope compartment be elevated to arbitrary height and unload.

The utility model is realized by following scheme: it has drive system 1 and driver behavior system 2, on the crossbeam 14 of automobile, has compartment 6, the bottom dress dump ram 7 in compartment 6, different is that a fixed mount 4 is housed on automotive frame 14, fixed mount 4 upper ends are connected with pivoted frame 12, the other end of pivoted frame 12 links to each other with compartment underframe 8, between fixed mount 4 and pivoted frame 12, be connected with oil cylinder 3, between pivoted frame 12 and compartment underframe 8, be connected with oil cylinder 11, oil cylinder 3 and oil cylinder 11 advance in proportion synchronously, thereby constitute jacking system of the present utility model.As Fig. 2, shown in Figure 4.

According to such scheme, owing to just on the basis of original structure, increased a jacking system, thereby the utility model still can be finished the various tasks that existing dumping truck can be finished, simultaneously, when the needs automobile when high bit is unloaded, then open oil cylinder 3 and oil cylinder 11, because the propelling of oil cylinder 3 turns forward compartment 6, simultaneously again because the propelling of oil cylinder 11 recedes compartment 6, because of this two oil cylinders are synchronization actions in proportion, so the synthetic compartment 6 that makes of above-mentioned two motions upwards rises abreast, when being raised to required height, close hydraulic circuit, just can make the compartment remain on this height, at this moment open dump ram 7, just can finish the task of high-order self-unloading.By above-mentioned analysis, the utility model is to finish lifting action with the synthetic principle of motion, its structure is very easy, the lifting action in compartment and the action of tumbling can be carried out respectively, do not disturb mutually, thereby, it is except that the function with fixed type dumping truck, can also carry out the task of self-unloading even loading in the higher position, vehicle in use is directly to the railway carriage discharging and in many occasions such as building, mineral products, uses this High-Dump Wagon to suit especially and convenient.

Fig. 1 is the front view of the utility model when not raising and the scheme drawing of compartment self-unloading.

The main diagrammatic sketch that Fig. 2 is the utility model when raising and the scheme drawing of compartment self-unloading.

Fig. 3 is the block diagram of the utility model jacking system.

Fig. 4 is a structure principle chart of the present utility model.

Fig. 5 is hydraulic circuit figure of the present utility model.

Embodiment of the present utility model such as Fig. 2, shown in Figure 3, fixed mount 4 is installed on the automotive frame 14, fixed mount 4 can be provided with base 13 and join together with it, base 13 can link with automotive frame or be integrally welded, above fixed mount 4, link to each other with pivoted frame 12 by bearing pin 5, pivoted frame 12 links to each other with compartment underframe 8 by an end of its folding arm, compartment underframe 8 is provided with compartment 6, and it is continuous by bearing pin 10, between compartment underframe 8 and compartment 6, also be provided with dump ram 7, oil cylinder 11 between pivoted frame 12 and compartment underframe 8 is the sleeve oil cylinder, this helps the layout of structure, oil cylinder 3 belows that are installed in fixed mount 4, one end and pivoted frame 12 are hinged, and the framework of whole jacking system is symmetric figure.Hydraulic circuit of the present utility model as shown in Figure 5, it has two gas controls, two position four-

way valves

15,16, the cavity of resorption of oil cylinder 3 communicates with valve 15, the epicoele of oil cylinder 3 communicates with oil cylinder 11 cavity of resorptions, can make these two oil cylinders advance synchronously in proportion like this, when valve 16 was opened, if valve 15 is motionless, then hydraulic oil entered oil cylinder 3 and oil cylinder 11, compartment 6 is raise, close oil pump, the compartment is raise stop, if open oil pump and open valve 15, then dump ram 7 actions, make compartment 6 inclination self-unloadings,

valve

15,16 returns, then

dump ram

7 and 11,3 bounce back under the compartment action of gravity automatically, in the time need not raising, can open valve 15 earlier, after open valve 16, then tumble in position in the compartment.

Claims

1, a kind of High-Dump Wagon, it has drive system 1 and driver behavior system 2, on the crossbeam 14 of automobile, has compartment 6, dump ram 7 is equipped with in the bottom in compartment 6, it is characterized in that on automotive frame 14, being equipped with a fixed mount 4, fixed mount 4 upper ends are connected with pivoted frame 12, the other end of pivoted frame 12 links to each other with compartment underframe 8, between fixed mount 4 and pivoted frame 12, be connected with oil cylinder 3, between pivoted frame 12 and compartment underframe 8, be connected with oil cylinder 11, oil cylinder 3 and oil cylinder 11 advance in proportion synchronously, constitute jacking system.
