Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, in particular to a sideways tipping closed dump truck compartment. Background Art

[0002] With the rapid economic growth and the increase in cargo flow, users have put forward higher requirements for the cargo capacity of vehicles. On the basis of a certain total mass, the lighter the curb weight, the greater the loading mass, and the higher the economic benefits. However, the traditional dump trucks on the market currently have the following problems: 1. Most of the dump truck side plate structures are of two types: field-shaped side plates and double V-shaped side plates. The field-shaped side plates have more ribs, heavier weight, more welds, and larger welding deformations. The V-shaped side plate structure has lower side plate strength and is prone to material accumulation and box expansion, which can no longer meet users' demands for vehicles.

[0003] 2. Traditional dump trucks are generally not designed with airtight covers. During the transportation process, the vehicles are prone to causing construction waste, slag, etc. to be scattered during driving, which will cause serious pollution to the environment and is also a safety hazard to other vehicles and pedestrians.

[0004] 3. Traditional dump trucks are generally lifted at the front and unloaded at the rear. The height of the lifting jack is restricted by the length of the car body. The longer the car body, the longer the jack is required. However, the design of the jack is incremental, the top is relatively slender, and the lateral stability is poor. During the unloading process, the car body is very likely to tilt. In addition, when the weight of the transported materials is heavy, it is very likely that the entire car body will roll over, which has a high risk factor. The unloading speed is also very slow, and the unloaded materials are easy to scratch the vehicle tires.

[0005] 4. Traditional dump truck lifting uses air-controlled hydraulic control to lift, which has problems such as reduced stability, increased failure rate, and low work efficiency. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a side-tipping closed compartment, which can solve the problems of existing dump truck compartments, such as many side panel structures with multiple ribs, heavy weight or low side panel strength, easy material accumulation, box expansion, front lifting, the height of the lifting jack is restricted by the length of the compartment, poor lateral stability, and the compartment is very likely to tilt during unloading and the unloaded materials are likely to scratch the vehicle tires.

[0007] In order to solve the above problems, the technical solution of the present invention is: the dump truck compartment structure includes a box body, a top cover welding assembly, a box body driving hydraulic cylinder, a straight connecting rod, a unloading driving hydraulic cylinder, a top cover driving hydraulic cylinder, a curved connecting rod and a right side open plate assembly.

[0009] The bottom side of the right side open edge panel assembly is provided with several sets of matching flip pins and flip pin sleeves at intervals, and the two side surfaces are provided with sealing plates that fit with the front end panel and the rear end panel; the bottom side of the right side open edge panel assembly is hinged to the bottom plate through the flip pin sleeves and flip pin sleeves; a bottom plate hinge ear is provided on the right side of the bottom of the bottom plate of the box body, and the bottom plate of the box body is hinged to the vehicle underframe through the bottom plate hinge ear and the hinge shaft.

[0010] The upper left end of the front end plate and the upper left end of the rear end plate are respectively hinged to one end of a compartment driving hydraulic cylinder; the other end of the compartment driving hydraulic cylinder is hinged to the vehicle underframe.

[0011] The upper middle part of the front end plate and the upper middle part of the rear end plate are respectively hinged to one end of the unloading driving hydraulic cylinder, and the other end of the unloading driving hydraulic cylinder is correspondingly hinged to the middle parts of the front and rear sides of the right side open edge plate assembly.

[0012] The middle of the top ends on both sides of the top cover welding assembly are respectively hinged to one end of a straight connecting rod, and the other end of the straight connecting rod is hinged to the left side of the upper end of the front end plate and the left side of the upper end of the rear end plate; the side ends on both sides of the top cover welding assembly are respectively hinged to one end of a curved connecting rod, and the other end of the curved connecting rod is hinged to the left side of the middle of the front end plate and the left side of the upper middle of the rear end plate; the lower middle part of each curved connecting rod is hinged to one end of a top cover driving hydraulic cylinder, and the other end of the top cover driving hydraulic cylinder is hinged to the right side of the front end plate and the right side of the rear end plate.
