In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments.

As shown in fig. 1-4, a schematic diagram of a composite protection device with lateral stability and limiting function is shown, which includes a wagon box assembly 1, a limiting assembly 2, a limiting block 5, an auxiliary frame 7 and a lateral stabilizer 3. Specifically, spacing assembly 2 is installed at the lower terminal surface of carriage assembly 1, and stopper 5 is equipped with two, and two stoppers 5 are installed respectively on the left and right sides inner wall of sub vehicle frame 7. The upper end of the transverse stabilizer 3 is hinged to the limiting assembly 2, and the lower end of the transverse stabilizer 3 is hinged to the auxiliary frame 7. Through the folding of above-mentioned transverse stabilizer 3, the technological effect that can realize is that spacing assembly imbeds between two stopper 5, can prevent the lateral shifting of whole carriage assembly 2, improves the transverse stability of whole car. The connection relationship of the components for the above details is as follows:

the transverse stabilizer 3 has to meet the folding effect and specifically comprises a first roll-over stand 31 and a second roll-over stand 32, wherein the first roll-over stand 31 and the second roll-over stand 32 are hinged together end to end, the upper end of the first roll-over stand 31 is fixed on the limiting assembly 2, the second roll-over stand 32 is hinged on the inner wall of the auxiliary frame 7, and the hinge point of the second roll-over stand 32 is arranged behind the limiting block 5. The first roll-over stand 31 and the second roll-over stand 32 are ladder-shaped, and the first roll-over stand 31 and the second roll-over stand 32 are mutually folded to realize that the limiting assembly is embedded between the two limiting blocks 5.

To explain further, the width of the restraining assembly 2 is greater than the width of the lateral stabilizer 3, so that the lateral stabilizer 3 can be conveniently connected to the restraining assembly 2. The specific structure of the limiting assembly is as follows:

the limiting assembly 2 comprises a connecting plate 21, a hinged plate 22 and a clamping plate 23, and the number of the hinged plate 22 and the clamping plate 23 is two. The two hinge plates 22 are connected together by a connecting plate 21, and the two hinge plates are vertically installed at both ends of the connecting plate 21. The card-in plate 23 is positioned at the lower end of the hinged plate 22, the angle between the card-in plate 23 and the hinged plate 22 is 135 degrees, and the side surface of the card-in plate 23 is vertically fixed on the connecting plate 21.

The limiting assembly 2 is integrally welded on the lower end face of the carriage assembly 1, the two hinged plates are used for connecting the first roll-over stand 31, the clamping plate 23 located at the lower ends of the hinged plates is convenient to clamp into the limiting blocks 5, and the distance between the two limiting blocks is ensured to meet the requirement that the hinged plates are tightly clamped into the limiting blocks 5.

In order to realize the rigid support of the wagon box assembly and the support protection for the lifting and maintenance of the wagon box assembly during the vehicle maintenance process, the present embodiment further provides a supporting rod 6, wherein both ends of the supporting rod 6 are fixed with L-shaped connecting pieces 4, and the other ends of the L-shaped connecting pieces 4 are hinged on the limiting blocks 5. The above-mentioned technical effect is achieved by the fact that the l-shaped connecting member 4 is flipped up around the hinge point, and the stay bar 6 is just placed on the stopper 5. When the L-shaped connecting piece 4 is turned downwards around the hinge point, the stay bar 6 is driven to turn away from the limiting block 5, and is specifically positioned in front of the limiting block 5.

In order to realize that the lower end of the limiting assembly 2 is clamped on the support rod 6, the carriage assembly is supported, and maintenance of maintenance personnel is facilitated. The lower extreme of card income board 23 is equipped with the arc recess, and the arc recess is convenient for block of vaulting pole, is convenient for spacing.

In this embodiment, when the dump truck is in a fully loaded transport state: the carriage assembly 1 is pressed downwards, and the limiting assembly 2 is clamped into the limiting block 5. Specifically, the snap-in plate 23 is snapped into the stopper 5 to drive the hinged plate to be tightly snapped into the stopper 5. The transverse swing of the carriage assembly 1 is limited through the interaction of the limiting assembly 2 and the limiting block 5, and the direct impact of the transverse force of the carriage assembly 1 on the overturning shaft and the hydraulic cylinder is reduced. Meanwhile, the limiting block 5 is embedded in the auxiliary frame 7, so that chassis accessories are prevented from being interfered, the utilization space of the chassis is saved, and the stress mode of the embedded limiting block 5 is more advantageous and not easy to fall off and lose efficacy.

When the carriage assembly 1 is lifted and unloaded, the carriage assembly 1 is hinged with the auxiliary frame 7 through the first roll-over stand 31 and the second roll-over stand 32, so that the carriage assembly is supported, and damage to the roll-over rotating shaft and the hydraulic cylinder, caused by the gravity center shift of goods, of the carriage assembly is effectively avoided.

When the vehicle is maintained, the L-shaped connecting member 4 is turned upwards around the hinge point to drive the stay bar 6 to be just placed on the limiting block 5. The carriage assembly falls down to drive the first roll-over stand 31 and the second roll-over stand 32 to fold, the clamping plate 23 is just clamped on the support rod, and then the carriage assembly 1 and the auxiliary frame 7 are slightly opened to reach the state shown in the figure 4. The rigid support between the stay bar and the limiting assembly 2 plays a role in supporting the carriage and protecting the operating personnel.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention.
