AI Technical Summary
During the flip of the goods, the center of gravity shifts due to the stickiness and unevenness of the goods, which increases the risk of rollover and affects the safety of the operation.
An automatic control system for lifting and rolling upwards of dump trucks is designed. By installing an inclination sensor in the front of the large cabin, an automatic level controller, a voice alarm and a limit valve are installed in the cab. These components are used to detect and prevent the inclination of the large cabin from exceeding the safety angle and prevent rolling up.
It effectively improves the safety performance of dump truck operations, prevents overturn accidents, standardizes the driver's operations, and ensures operation safety.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dump trucks, and in particular relates to an automatic control system for lifting and preventing rollover of a dump truck. Background Art
[0002] Dump trucks are mainly used for bulk cargo operations such as laterite nickel ore, non-ferrous ore, bauxite, iron ore, and fertilizers. During the operation, the goods are easily stuck in the cargo compartment and cannot be completely emptied. The goods do not necessarily flow vertically downward when emptying. The driver may lift the cargo compartment to the highest height, resulting in a large shift in the center of gravity of the vehicle. The uneven road surface of the terminal site poses a risk of vehicle rollover. Summary of the invention
[0003] In order to prevent personal injury and equipment damage caused by dump truck rollover and improve the operating safety of dump trucks, an automatic control system for dump truck lifting and anti-rollover is proposed. The tilt sensor, automatic level control system, limit valve and other components are used to prevent the dump truck from rolling over.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] The dump truck lifting and anti-rollover automatic control system includes a dump truck, and is characterized in that: an inclination sensor is installed at the front of the dump truck's compartment, an automatic level controller, a voice alarm and a limit valve are installed in the cab, the output end of the inclination sensor is connected to the input end of the automatic level controller, the output end of the automatic level controller is connected to the voice alarm and the limit valve, and the limit valve is connected to the lifting valve. The automatic level controller sets the maximum value of the safety angle.
[0006] Furthermore, the limit valve adopts a two-position three-way limit valve.
[0007] Furthermore, each part or module of the system is connected by wires.
[0008] The following beneficial effects can be obtained through the above technical solution:
[0009] The utility model has the characteristics of reasonable design, simple structure, easy use, safety and reliability, high working efficiency, etc., which greatly improves the safety performance of dump truck operation. At the same time, it can better regulate the driver's operation and always remind him to abide by the safe operation procedures. The utility model has been applied in three Sinotruk dump trucks in the Mayao operation area, which are installed with the anti-rollover automatic control system and are in good use. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram.
[0011] Figure 2 It is a schematic diagram of installation of an embodiment.

[0013] In the figure: 1. Dump truck; 2. Tilt sensor. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings:
[0015] like Figure 1-2 As shown, an inclination sensor is installed at the front of the dump truck's compartment, and an automatic level controller, a voice alarm, and a limit valve are installed in the cab. The output end of the inclination sensor is connected to the input end of the automatic level controller through a wire, the output end of the automatic level controller is connected to the voice alarm and the limit valve, and the limit valve is connected to the lifting valve.
[0016] Figure 2 As shown, by installing a tilt sensor 2 on the top of the dump truck compartment, the tilt angle of the compartment is sensed. An automatic level control display, a voice alarm device, an intermediate relay, a limit valve and other components are configured in the cab, and the components are connected with a wiring harness. During the operation of the dump truck, if the tilt angle of the compartment exceeds the set maximum safety angle after the compartment is lifted, the voice alarm device will start to alarm and stop the lifting action of the compartment through the limit valve, thereby preventing the compartment from rolling over.
[0017] In the above embodiment, the inclination sensor specifically adopts the seismic-resistant CQ2-400 angle sensor and UT-1 automatic level controller produced by Qingdao Youtian Measurement and Control Technology Co., Ltd., the voice prompter produced by Shenzhen Chenghui Technology Co., Ltd., and the two-position three-way limit valve produced by Delixi. The above-mentioned various components are installed in the above embodiment and connected according to the electrical schematic diagram. Finally, the two-position three-way limit valve needs to control the lifting valve of the dump truck. The above-mentioned connection can be realized by those skilled in the art.
[0018] In actual application, through continuous testing, the maximum safety angle of the automatic level controller is set to 2.8 degrees.
[0019] The above are all preferred implementations of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
