Description

Technical Field

[0001] The invention belongs to the technical field of transport vehicle design and manufacturing, and relates to a container transport anti-rollover and dumping unloading semitrailer with an unloading support mechanism. Background Art

[0002] Container transportation is widely used in all walks of life. In particular, in recent years, 20-foot 35-ton open-top containers have been promoted and applied on railways for long-distance railway transportation of bulk raw materials such as coal, sand and gravel aggregates, and combined with short-distance road transportation, effectively complementing each other's advantages and promoting cost reduction and efficiency improvement in industry transportation. Semi-trailer skeleton vehicles are used for road transportation of containers. Existing skeleton vehicles are used for open-top container transportation, which do not have a rear-tilting system and cannot meet the unloading requirements.

[0003] In the whole process of open-top container transportation, bulk material loading and container lifting have been mechanized. However, in the bulk material unloading stage, because conventional container transport skeleton semi-trailers do not have the ability to unload by themselves, they need to use additional equipment, such as large vehicle tipping platforms for unloading, and even need to increase the container lifting operation process, and transfer the container to a special container unloading mechanism to finally realize bulk material unloading. This greatly affects the transportation efficiency of the container throughout the route. In addition, when container transport vehicles are on uneven roads or in an overloaded state, there is no effective detection alarm and intervention means, and rigid heavy-load lifting and unloading can easily cause vehicle rollover accidents.

At the same time, after the control module logic calculation, it is determined whether the air circuit electromagnetic control valve of the control module intervenes in the vehicle lifting process, that is, when the lifting frame is in the real-time monitoring angle of the vehicle's forward direction or the real-time monitoring angle of the lifting frame in the vehicle's width direction. When it is greater than the corresponding angle value set in advance, the vehicle driving direction or vehicle width direction indicator light of the corresponding alarm assembly lights up, the buzzer alarms, and the air circuit solenoid reversing valve is started at the same time to forcibly change the lifting air circuit direction and control the lifting cylinder to perform a descending operation to prevent the vehicle from tipping over when lifted; when any value of the real-time monitoring angle of the lifting frame in the vehicle's forward direction or the real-time monitoring angle of the lifting frame in the vehicle's width direction is not greater than the corresponding angle value set in advance, the air circuit solenoid control valve circuit of the control module is not connected and will not intervene in the vehicle lifting process. The vehicle can complete normal lifting and dumping operations.

[0068] In this embodiment, the vehicle running system 8 is composed of three 10t axles, 12 tires and rims, 4 leaf springs, a steel suspension, etc.

[0069] like Figure 2As shown, this embodiment is provided with an accessory assembly 9, which includes a leg assembly, a side protection assembly, a toolbox assembly, a fender assembly, and a rear protection assembly. The leg assembly is composed of a leg mounting seat and a lower leg. The leg mounting seat is a cold-bent groove-shaped part, and the lower leg is an industry standard part. The leg mounting seat is welded to the web plate 1-2-2 of the rear longitudinal beam of the frame, and the lower leg is bolted to the leg mounting seat. The side protection assembly, the toolbox assembly, and the fender assembly are connected by bolts through a connecting plate welded to the frame. The rear protection assembly is welded to the frame.

[0070] Operation process: When the container needs to be lifted and dumped, the unloading safety support assembly 6 is first supported to the ground, and then the tractor hydraulic power system is controlled by the hand-controlled air valve to supply high-pressure oil to the lifting cylinder, driving the tipping mechanism 2 lifting frame assembly 2-1 and the container to rotate around the hinged shaft of the flip beam assembly. Synchronously with the vehicle lifting, the anti-roll control system 7 installed on the vehicle longitudinal beam triggers the switch to disengage the lifting frame and start the anti-roll control system. The angle detection assembly installed on the lift frame crossbeam detects the angle of the lift frame with the horizontal plane in the vehicle's forward direction and vehicle width direction in real time, and transmits it for logical comparison with the preset value of the anti-roll system logic processor. When the lifting angle of the lift frame exceeds the preset value or the vehicle width direction angle of the vehicle at the dumping site (including the vehicle rolling in the vehicle width direction during the lifting process) exceeds the preset value, the anti-roll system air circuit electromagnetic reversing valve installed on the cylinder lifting air control route intervenes to change the air circuit path from the manual air valve from lifting to lowering, thereby causing the air-controlled reversing valve to change the flow direction of the high-pressure oil circuit of the lifting hydraulic system, thereby achieving safe operation control of lifting and falling when there are safety hazards and smooth lifting and dumping when there are no safety hazards, thereby achieving safe control of heavy-load lifting.
