An articulated dump truck container assembly and its loading and unloading method

Abstract

The invention discloses a hinged dumper container assembly, and loading and unloading methods thereof. The container assembly comprises a rear frame and a container, wherein the rear frame comprises a rear frame longitudinal beam assembly, a frame anti-torsion tube, a rear frame lifting seat, a lower hinge seat, a lower bolt seat and a hinge body bearing; the container comprises a bottom plate, a rear tilted plate, a left side plate, a right side plate and a front plate, a left longitudinal beam and a right longitudinal beam are arranged on the left side plate and the right side plate respectively, a left lifting support seat and a right lifting support seat bulging out of the left longitudinal beam and the right longitudinal beam are arranged on the left longitudinal beam and the right longitudinal beam respectively, and an upper hinge seat and an upper bolt seat are arranged at the bottom of the container. The loading method is as follows: returning the container, and loading materials in the container; the unloading method is as follows: turning the container by a lifting oil cylinder, and when the container is turned to a certain position, connecting the upper bolt seat with the lower bolt seat by a bolt; during the turnover process of the container, the materials are detached from the container. The container assembly, and the loading and unloading methods thereof disclosed by the invention are capable of improving the anti-torsion capacity of the frame, improving the bearing capacity and strength of the lifting support seat realizing location for the container, and improving the safety performance of loading and unloading.

Description

technical field [0001] The invention relates to an articulated dump truck, in particular to a container assembly of the articulated dump truck and a loading and unloading method thereof. Background technique [0002] Now there is a frame of an articulated mining dump truck that generally includes a front frame and a rear frame. The vehicle frame and the rear vehicle frame are connected by a hinge. In order to be able to support the huge car body structure, the overall frame is generally a rigid structure, and the overall layout design of the frame should be reasonable. When the dump truck is driving on a rugged mountain road, the body is subjected to a large vibration. Since the rear end of the cargo box and the rear frame is hinged, and the front end is connected by a lifting cylinder, if there is no shock absorption and limiter between the rear frame and the compartment When the dump truck is running, there is a misalignment between the cabin and the rear frame, which af...

Problems solved by technology

When the dump truck is driving on a rugged mountain road, the body is subjected to a large vibration. Since the rear end of the cargo box and the rear frame is hinged, and the front end is connected by a lifting cylinder, if there is no shock absorption and limiter between the rear frame and the compartment When the dump truck is running, the misalignment between the compartment and the rear frame will affect the performance of the lifting cylinder

[0003] For mining dump trucks, the cargo box is one of the important components of the dump truck. The dump truck must realize self-loading and unloading. The rear end of the cargo box is hinged on the rear frame. Lifting oil cylinders are installed between the frames, and the existing lifting oil cylinders are connected by supports. For example, the application publication number is CN102211614A, and the application date is May 9, 2011. The application publication date is October 12, 2011. The applicant is Beijing Science and Technology Co., Ltd. The patent literature of the university discloses an AC drive articulated dump truck, and specifically discloses that the dump truck mainly includes a frame, an electric wheel unit, wheels, a cab, a cargo box, a power system, and an articulated body. Supports are installed on both sides of the rear frame of the car, and lifting supports are installed on both sides of the cargo box, and a lifting cylinder is hinged between the supports and the lifting supports on each side, such as figure 1 As shown, the width of the vehicle frame 1 is less than the width of the container 4. After the lifting cylinder 6 is installed, it is inclined outward from bottom to top. The lifting support will be subjected to an outward force F 1 and an upward force F 2 , and when the lifting support is generally welded on the cargo box, and the stress concentration is easily formed at the weld, therefore, after being subjected to the above F 1 and F 2 , the lifting support is easy to break and fail, and in severe cases, major accidents will occur

[0004] The vehicle frame of the above-mentioned patent document is provided with a hinge block at the front end, which is used to install the hinged body. , the cargo box is prone to left and right deflection, and when the cargo box is lowered and in contact with the frame, the cargo box cannot be positioned, so it is easy to damage the lifting cylinder and the hinge pin, and in serious cases, it will cause major damage. ACCIDENT

[0005] In addition, when the cargo box is lifted, if the Jushen oil cylinder fails, the cargo box will quickly return to its position, and because the cargo box of the mining dump truck is heavy, the cargo box is easy to damage the frame due to gravity. components, and personal safety accidents may occur
