[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example 1

[0022] like Figure 1As shown, an anti-rollover dump truck includes a first level sensor 3 installed on the front and rear sides of a cargo box 2 on a vehicle body 1, and a second level sensor 4 installed on the left and right sides of the cargo box 2, respectively. The number of the first level sensor 3 and the second level sensor 4 are both two. A controller 6 connected to a lifting hydraulic rod 5 is installed on the vehicle body 1. The controller 6 controls the action of the lifting hydraulic rod 5. The lifting hydraulic rod 5 is used to lift the cargo box 2. The first level sensor 3 and the second level sensor 4 are both electrically connected to the controller 6.

[0023] The first horizontal sensor 3 is used to monitor the lifting angle of the cargo box 2 in real time, and the second horizontal sensor 4 is used to monitor the horizontal angle of the cargo box 2 in real time. The first horizontal sensor 3 and the second horizontal sensor 4 transmit the lifting angle and horizontal angle signals of the cargo box 2 during the lifting process to the controller 6 in real time. By setting the critical values ​​of the lifting angle and the horizontal angle in the controller 6, it is determined whether there is a risk of rollover of the vehicle body 1. After the risk of rollover is found, the controller 6 promptly sends a stop lifting or fall back signal to the lifting hydraulic rod 5.

[0024] In combination with the above, the present application monitors the unloading process of the cargo box 2 in real time through the first level sensor 3, the second level sensor 4 and the controller 6 connected to the lifting hydraulic rod 5. When it is found that there is a risk of rollover of the cargo box 2, the controller 6 promptly controls the lifting hydraulic rod 5 to stop lifting or falling back to prevent rollover during continued unloading, thereby reducing the risk of rollover of the vehicle body 1 and effectively solving the problem that the current dump trucks are prone to rollover during unloading on non-hardened roads.

[0025] Example 2

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the structure of this embodiment is substantially the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. In order to further avoid the risk of rollover, in this embodiment, the center of gravity of the vehicle body 1 is timely adjusted during the lifting process of the cargo box 2 to avoid a large change in the horizontal tilt angle;

[0027] Specifically, in this embodiment, a sliding box 7 adapted to the interior of the cargo box 2 is slidably connected to the cargo box 2. The sliding box 7 is U-shaped as a whole to facilitate the storage of the goods falling into the cargo box 2. The end of the sliding box 7 away from the cargo box 2 outlet is closed;

[0028] The sliding box 7 is U-shaped and closed at one end, so it can slide toward the cargo outlet of the cargo box 2 when the cargo box 2 is tilted. At the same time, the cargo moves with the sliding box 7 during the sliding process, and the center of gravity of the vehicle body 1 changes accordingly, and will not increase with the rise of the cargo box 2, thereby increasing the risk of the vehicle body 1 rolling over.

[0029] In order to facilitate the sliding box 7 to slide in the cargo box 2, guide wheels 8 are installed on both sides and the bottom of the cargo box 2. At least one row of guide wheels 8 facing the cargo box 2 outlet is arranged on both sides and the bottom of the cargo box 2. The number of guide wheels 8 on each side of the cargo box 2 is not less than two. In this embodiment, the number of guide wheels 8 on the bottom side of the cargo box 2 is four and arranged in two rows. A slideway 9 compatible with the guide wheel 8 is installed on the sliding box 7, and the slideway 9 is perpendicular to the cargo box 2 unloading port; the setting of the guide wheel 8 and the slideway 9 facilitates the movement of the sliding box 7 in the cargo box 2.

[0030] At the same time, in order to facilitate the limitation of the moving speed of the sliding box 7 in the cargo box 2 and prevent the sliding box 7 from moving too fast in the cargo box 2, an adjusting hydraulic rod 10 is installed between the cargo box 2 and the sliding box 7. The adjusting hydraulic rod 10 is parallel to the slide 9. One end of the adjusting hydraulic rod 10 is fixedly connected to the cargo box 2, and the other end of the adjusting hydraulic rod 10 is fixedly connected to the sliding box 7. The adjusting hydraulic rod 10 is connected to the controller 6, and the action of the adjusting hydraulic rod 10 is controlled by the controller 6 to control the movement of the sliding box 7, thereby adjusting the center of gravity of the vehicle body 1 in time and reducing the risk of rollover.

[0031] Example 3

[0032] like Figure 3 and Figure 4 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In order to prevent the sliding box 7 from touching the ground after moving out of the unloading port of the cargo box 2, which affects the unloading, in this embodiment, a clearance plate 11 is rotatably connected to the bottom of one end of the sliding box 7 close to the unloading port of the cargo box 2. Through the setting of the clearance plate 11, after the sliding box 7 is moved out of the cargo box 2, the clearance plate 11 can be rotated toward the vehicle body 1 to expand the unloading space and facilitate unloading.

[0033] At present, the technical solution of this application has been put into pilot production, that is, a small-scale experiment before the large-scale mass production of the product; after the pilot production was completed, a user usage survey was carried out in a small range, and the survey results showed that user satisfaction was high; now we have begun to prepare for the formal production of the product for industrialization (including intellectual property risk warning survey).
