[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0033] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0034] like Figure 1 , 2 As shown, the utility model provides an anti-rollover type unloading platform, comprising: a chassis 10, which is horizontally arranged on the ground, and a hydraulic component is arranged in the chassis; an unloading platform 20, which is arranged on the chassis, and one side of the unloading platform is hingedly arranged with the chassis, and the lower bottom surface of the unloading platform is hingedly arranged with the hydraulic component in the chassis; the unloading platform includes two slide grooves 30, which are parallel to each other and transversely arranged on the unloading platform, and the two slide grooves are embedded in the upper top surface of the unloading platform; a pair of blocking frames 40, which are slidably arranged on the two through sliders 50 On the slide, a pair of baffles are extended in parallel with each other in the length direction of the unloading platform, and the length of the pair of baffles is adapted to the length of the unloading platform; a pair of hydraulic cylinders Ⅰ 60 are horizontally arranged on both sides of the unloading platform, and the bases of the pair of hydraulic cylinders Ⅰ are respectively hinged to the two sides of the unloading platform, and the front ends of the pair of hydraulic cylinders Ⅰ are respectively hinged to the outer side walls of the pair of baffles; a wheel stopper 70 is arranged at one end of the unloading platform, and the wheel stopper and the pair of baffles do not contact each other; a pedal 80 is respectively inclined and connected at the other end of the chassis.

[0035] In this solution, the chassis is used to support the unloading platform, and the hydraulic assembly drives the unloading platform to flip at a certain angle relative to the chassis, so as to drive the truck thereon to roll over and unload.

[0036] A pair of baffles extending parallel to each other are arranged on the unloading platform. In the initial working state, the pair of baffles are placed close to the outermost side of the unloading platform. When the truck drives into the designated position on the unloading platform, the pair of baffles are driven to the two sides of the truck by a pair of hydraulic cylinders I respectively, and clamp and fix the two sides of the truck to effectively stabilize the truck. When the unloading platform overturns, the pair of baffles are effectively supported at multiple points by a pair of hydraulic cylinders I, two slide grooves and sliders thereon, and no deviation will occur. The structure is stable and the stabilization effect is good. After unloading is completed, the pair of baffles are driven to move outward to the initial working state without affecting the entry and exit of trucks.

[0037] A pair of hydraulic cylinders I respectively drive and control a pair of baffles independently, and can be adjusted as needed according to the different distances between the truck and the pair of baffles, thereby reducing the parking position requirements for the truck.

[0038] Wheel chocks are used to stabilize the front wheels of a truck and help the truck to move into position.

[0039] The pedal provides a ramp for the truck to drive onto the unloading platform.

[0040] In this solution, the anti-vehicle rollover unloading platform provided by the utility model can provide flexible and effective stable support for the front wheels and left and right sides of the truck to prevent the vehicle from rolling over, and has a simple structure and is easy to use.

[0041] like Figure 3 As shown, in a preferred solution, any of the pair of baffles further includes: a receiving groove 401, which is arranged on the other side wall of any baffle in the unloading platform, and the receiving groove is extended along the length direction of any baffle; a pair of slide plates 402, which are slidably arranged in the receiving groove; a pair of hydraulic cylinders II 403, which are horizontally extended and arranged between the pair of slide plates in parallel with each other, and the front ends of the pair of hydraulic cylinders II are respectively hinged to the pair of slide plates, and the bases of the hydraulic cylinders II are respectively hinged to the receiving groove; rubber pads 404, which are respectively arranged on the front end surfaces of the pair of slide plates; and a pressure sensor, which is arranged in the rubber pad. The pair of slide plates are slidably arranged in the receiving groove, and the distance between the pair of slide plates can be adaptively adjusted according to the distance between the front and rear wheels of the truck, so that the pair of slide plates are driven by the pair of hydraulic cylinders II to slide to the front and rear wheels facing the truck, and then the pair of hydraulic cylinders I drive the pair of baffles to approach and resist the truck and its front and rear wheels. The rubber pads are used to buffer and protect the front and rear wheels and increase friction to provide stability. The pressure sensor is used to detect the pressure of the pair of slide plates on the front and rear to avoid excessive pressure and ensure safe production.

[0042] In a preferred solution, the height of a pair of baffles is greater than 30 cm, and a pair of baffles has a certain height, which can effectively improve the stability of the truck while ensuring that the opening and closing of the container side door are not blocked.

[0043] like Figure 4 , 5 As shown, in a preferred embodiment, the hydraulic assembly includes at least two hydraulic cylinders 101, which are respectively arranged at two ends of the chassis to provide stable support for the rollover operation.

[0044] In a preferred solution, among a pair of baffles, the height of any baffle set on the side where the unloading platform and the chassis are hinged is lower than the height of any baffle set on the other side; the height of any baffle set on the side where the unloading platform and the chassis are hinged is lower than the bottom surface height of the container on the truck. The side where the bulk cargo dump truck platform and the chassis are hinged in the container is tipped, so the height of any baffle on this side cannot exceed the height of the lower edge of the side door of the container, while any baffle on the other side can be set relatively higher to provide lateral pressure support to the truck, so as to maintain the stability of the truck and the container during the unloading process.

[0045] like Figure 6 As shown, in a preferred embodiment, the pedal and the chassis are hinged at their joints, and the pedal further comprises a hydraulic cylinder III 801, which is arranged below the pedal, and the bottom of the hydraulic cylinder III is hinged to the chassis, and the front end of the hydraulic cylinder III is hinged to the lower surface of the pedal. Driven by the hydraulic cylinder III, the pedal can rotate upward relative to the chassis with the hinge point as the center of the circle, thereby providing a certain shielding protection to the rear end of the truck during the unloading process to avoid accidents.

[0046] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
