Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the center of gravity of the compartment is too high and rolls over because the material at the rear of the compartment slides down before the material at the front of the compartment when the dump truck is unloading.

Embodiment 1

[0026] Such as image 3 As shown, a dump truck with anti-dump rollover includes a frame 1, a compartment 2 and a lifting mechanism 3. The rear portion of the compartment 2 is hinged with the rear portion of the vehicle frame 1, the lifting mechanism 3 is a hydraulic cylinder, and the front end of the compartment 2 is connected to the piston rod of the hydraulic cylinder. This dump truck uses a middle foldable compartment 2, which is made up of side frames and a floor, and the compartment 2 is divided into two parts, a front compartment 21 and a rear compartment 22 in the middle, and the front compartment 21 and the rear compartment 22 are Base plate hinged. The upper corner of the rear end of the front compartment side frame 21a has a triangular tenon 4, and the thickness of the tenon 4 is smaller than the thickness of the front compartment side frame 21a. The upper corner of the front end of the rear compartment side frame 22a has a tenon groove 5 matched with the tenon 4, ...

Embodiment 2

[0031] Such as Figure 6 As shown, on the basis of Embodiment 1, the beam 7 is fixed near the tenon 4 and the tenon groove 5 on the side frame of the carriage to reinforce and protect the folded part of the middle part of the carriage 2 . The beam 71 on the front compartment 21 is framed on the upper edges of the side frames 21a and 21b on both sides and close to the tenon 4, and its upper surface is flush with the upper surfaces of the side frames 21a and 21b. The beam 72 on the rear compartment 22 is added to the upper edge of the side frame 22a and the side frame 22b on both sides and close to the tongue and groove 5, and its upper surface is flush with the upper surface of the side frame 22a and the side frame 22b. In addition, longitudinal beams can also be added on the outside and / or inside of the rear compartment 22 corresponding to the beam 72 , and the longitudinal beam and the cross beam 72 are connected together to reinforce the tongue and groove 5 of the rear compa...

Abstract

The invention relates to a foldable compartment. The foldable compartment comprises side frames and baseplates. The compartment is divided into two parts including a front part and a rear part. The baseplates of the front and rear parts are hinged, and the junction of the side frames of the front and rear parts is of a movable meshing structure. An automatic-unloading trunk capable of preventing material unloading and lateral overturning using the foldable compartment comprises a trunk frame, the compartment and a lifting mechanism. One end of the compartment is hinged to one end of the trunkframe, one end of the lifting mechanism is connected to the other end of the trunk frame, and the other end of the compartment is connected to the other end of the lifting structure. The centrally foldable compartment is used for replacing conventional compartments. When materials are unloaded, the front part of the compartment rises first, and then the rear part of the compartment rises. Since aninclination angle of the front part of the compartment reaches a critical inclination angle of material falling earlier than the rear part of the compartment, materials at the front part of the compartment slides down first, and materials at the rear part of the compartment are pushed to slide down together. In this way, the problem is avoided that the compartment is laterally overturned due to the fact that the gravity center of the compartment is higher since the materials at the rear part of the compartment slide down earlier than the materials at the front part of the compartment.

Description

technical field [0001] The invention relates to a dump truck, in particular to a dump truck capable of preventing material rollover. Background technique [0002] The compartment of the dump truck is equipped with an automatic dumping device, and generally consists of a chassis, a hydraulic lifting mechanism and a compartment. When loading and unloading earthwork, gravel, and loose materials, since the loading compartment can automatically tip over to unload at a certain angle, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency, and reduces transportation costs. Dump trucks are commonly used transport machinery, which can be divided into backward tipping type and sideways tipping type according to the tipping direction of the compartment. When unloading, the movement of the piston rod of the hydraulic cylinder is controlled by the operating system, so that the carriage can be stopped at any desired inclined position....
