Problems solved by technology

For example, in the Chinese patent with application number 2020101444611 that the applicant previously applied for, its bottom plate is horizontal, and the goods cannot be centered automatically when loading, and the problem of the poor bending resistance of the horizontal bottom plate can only be solved by adding beams. Increased cost; in addition, the lower part of the side plate of this patent is bent inward and welded to the bottom plate, and the material in the carriage presses the bent part downward, and the bent part, especially the welded part, bears huge pressure and is prone to fatigue, bending deformation and even detachment after welding , especially when the side panel is provided with a folded and expanded structure with outward protrusions to increase capacity, this situation occurs faster

Embodiment 1

[0059] Such as Figure 1~6 As shown, a compartment for a dump truck or a dump semi-trailer, including a bottom plate 3, a side plate 2, a front plate 1 and a rear plate 4, wherein:

[0060] Specific as figure 2 As shown, the base plate 3 is provided with a sinking portion 301, the sinking portion 301 is located on the median line of the base plate 3, and extends along the length direction of the base plate 3;

[0061] Specific as image 3 As shown, the lower side of the side plate 2 is provided with a hooked portion 203, after the bottom plate 3 and the side plate 2 are welded, the hooked portion 203 is closed by the bottom plate 3 to form a hollow beam 6 to strengthen and protect the welded part.

[0062] In this embodiment, by designing the sinking part 301, the loaded material can automatically go to the middle, so as to achieve the purpose of automatically centering and lowering the center of gravity; The beam 6 improves the overall structural strength of the compartme...

Embodiment 2

[0064] On the basis of Example 1, such as figure 2 As shown in the right figure of , the sinking part 301 has a multi-level sinking structure, the sinking structure in the middle has the largest depth, and the sinking structures on both sides climb up in a ladder shape, and the sinking structure is about the midline of the bottom plate. symmetry.

[0065] The multi-stage sinking structure in this embodiment can improve the structural strength of the bottom plate 3 on the one hand, and facilitate the collection and flow of materials on the other hand.

[0066] Furthermore, in another embodiment, the two sides of the bottom plate 3 are provided with outward and upward oblique portions 302, the oblique portions 302 correspond to the hooked portions 203 of the side plates 2, and together constitute the Hollow beam6.

[0067] In this embodiment, the obliquely bent portion 302 is convenient for combined welding with the side plate 2 , and also makes the formed hollow beam 6 have ...

Embodiment 3

[0071] On the basis of Example 2, such as Figure 6 As shown, the inside of the hollow beam 6 forms a sliding channel;

[0072] The longitudinal beam 6 and the bottom plate 3 also form a sliding channel after being welded and fixed;

[0073] The vibrating unit 8 is movably arranged in the sliding channel, and the vibrating unit 8 generates vibration to vibrate the materials on the bottom plate 3 .

[0074] This embodiment makes full use of the internal structural space of the hollow beam and the longitudinal beam. The vibration unit slides freely in the sliding channel formed in the internal structural space. The material in the sinking part and the material in the connection between the side plate and the bottom plate are shaken off. On the one hand, this design can make full use of the structural space, avoid the vibration unit being placed outside the carriage and be easily damaged by collision, and avoid affecting the loading operation of the carriage; Avoid unnecessary...

Abstract

The invention discloses a carriage for a dump truck or a dump semitrailer, which comprises a bottom plate, side plates, a front plate and a rear plate, and is characterized in that the bottom plate isprovided with a sinking part, and the sinking part is positioned on the median line of the bottom plate and extends along the length direction of the bottom plate; hooking and folding parts are arranged on the lower sides of the side plates, and after the bottom plate and the side plates are welded, the hooking and folding parts are closed by the bottom plate to form a hollow beam so as to reinforce and protect a welding part. The sinking part is designed, so that loaded materials automatically move towards the middle, and the purposes of automatically centering and lowering the gravity center are achieved; and after the side plates and the bottom plate are welded and fixed, the hooking parts and the bottom plate form hollow longitudinal beams, so that the overall structural strength of the carriage is improved, particularly, the welding positions of the bottom plate and the side plates are reinforced and protected, the situation that the welding positions are broken is reduced, and the anti-swelling capacity of the side plates can be improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of material transportation machinery and equipment, more specifically, the invention relates to a compartment for a dump truck or a dump truck. Background technique [0002] Enlarging the compartment volume, lowering the center of gravity, reducing curb weight, and improving rigidity and strength are the improvement directions and demands of the compartment. For example, in the Chinese patent with application number 2020101444611 that the applicant previously applied for, its bottom plate is horizontal, and the goods cannot be automatically centered when loading, and the problem of the poor bending resistance of the horizontal bottom plate can only be solved by adding beams. Increased cost; in addition, the lower part of the side plate of this patent is bent inward and welded to the bottom plate, and the material in the carriage presses the bent part downward. The bent part, especially the welded part, bears...
