Description

Technical Field

[0001] The utility model relates to the technical field of dump truck alarm devices, in particular to an alarm device for dump trucks with excessively large tilt angles after a large compartment of the dump truck is lifted. Background Art

[0002] A dump truck is a vehicle that unloads its cargo by hydraulic or mechanical lifting. It consists of a vehicle chassis, a hydraulic lifting mechanism, a cargo compartment, and a power take-off device. The compartment of a dump truck can be divided into two types: backward tipping and side tipping. The piston rod is controlled by the operating system to push the piston rod to tip the compartment. Because the center of gravity changes after the compartment is lifted, there are many dump truck rollover accidents. Statistics show that the main reasons for the rollover of dump trucks are uneven ground, excessive ground inclination, unbalanced cargo loading, or cargo center offset, etc.

[0003] In reality, this factor has caused vehicles to roll over many times. After the vehicle rolls over, it is found that the beam, cab or cargo box are deformed during maintenance, resulting in high maintenance costs. After the maintenance, the vehicle is found to have serious abnormal noises during later use, resulting in a decline in the overall technical performance of the vehicle. When the angle between the horizontal plane of the dump truck and the ground is ≧30°, the vehicle is very likely to roll over sideways. In general, none of the dump trucks on sale have an alarm device for excessive tilt angles after the large compartment is lifted. Therefore, it is necessary to design an alarm device specifically for the large angle after the large compartment of the dump truck is lifted to avoid the above situation. Utility Model Content

[0004] The utility model aims to provide an alarm device for a dump truck whose tilt angle is too large after the dump truck compartment is lifted, which has reasonable structural design, convenient installation and operation, low processing and manufacturing cost, and safe and reliable use. When the angle of the dump truck compartment is too large after the dump truck compartment is lifted, an alarm is given in time to avoid rollover accidents.

[0005] The utility model discloses an alarm device for an excessively large tilt angle of a dump truck compartment after lifting, comprising an angle plate, a pointer hinged on a side wall of the angle plate, an end of the pointer fixedly connected to a first connecting line, and the first connecting line fixedly connected to a fuse; a second contact sensor and a first contact sensor are installed on the bottom surface of the angle plate, and the second contact sensor and the first contact sensor are symmetrically arranged, and are symmetrically arranged along the center line of the angle plate.

[0006] The first contact sensor is connected to the fourth connection line through the second connection line, the second contact sensor is connected to the fourth connection line through the third connection line, and the end of the fourth connection line is fixedly connected with a buzzer.

[0007] The angle plate can be installed in the cab of the dump truck, so that the angle plate and the cab are horizontally set, the pointer is 90° vertical to the cab, and the pointer is powered from the backup power supply in the cab, so that the pointer is in a normal power state. When the tilt angle between the horizontal plane of the dump truck and the ground is ≧30°, the pointer rotates and connects with the first contact sensor or the second contact sensor, and the buzzer sounds an alarm to remind the driver to interrupt the vehicle compartment lifting operation. Continuing the lifting action at this time may cause the vehicle to roll over; when the tilt angle between the horizontal plane of the dump truck and the ground is <30°, the pointer rotates and connects with the first contact sensor The sensor or the second contact sensor is disconnected, and the buzzer alarm stops; the dump truck compartment is connected to the main beam, and the vehicle body is perpendicular to the ground. When the dump truck compartment is lifted, the tire pressure, the center of gravity of the cargo, the flatness of the ground and other reasons cause the vehicle compartment to tilt to the left or right to varying degrees. At this time, the angle between the vehicle body and the ground changes. When the tilt angle exceeds a certain value, the vehicle will roll over; installing the device on the vehicle can effectively remind the operator, avoid safety accidents, reduce losses, and effectively protect the personal safety of the operator. It is easy to operate and safe and reliable to use.

[0008] In order to prevent the electrical circuit from being overloaded due to line faults during use, a 10A fuse is installed at the positive pole of the circuit. When short circuits, grounding and other faults occur in the electrical circuit, the system is protected and the reliability and durability of the device are improved.

[0009] The angle between the first touch sensor and the second touch sensor is 60°.

[0010] The angle between the first contact sensor and the second contact sensor is 60°. When the vehicle is parked on the horizontal ground, the angle is 30° on both sides of the vertical center line of the cab. This angle is the safe angle for lifting the dump truck compartment. When the tilt angle of the vehicle compartment does not exceed this range, the vehicle will be in a safe state. When the tilt angle exceeds the range after lifting, the device will alarm to remind the driver to terminate the operation, otherwise the vehicle may roll over.

[0011] Beneficial effects of the utility model:

[0012] 1) The angle plate can be installed in the cab of the dump truck, so that the angle plate and the cab are horizontally set, the pointer is 90° vertical to the cab, and the pointer is powered from the backup power supply in the cab, so that the pointer is in a normal power state. When the tilt angle between the horizontal plane of the dump truck and the ground is ≧30°, the pointer rotates and connects with the first contact sensor or the second contact sensor, and the buzzer sounds an alarm to remind the driver to interrupt the vehicle compartment lifting operation; when the tilt angle between the horizontal plane of the dump truck and the ground is <30°, the pointer rotates and disconnects from the first contact sensor or the second contact sensor, and the buzzer alarm stops, which can effectively remind the operator to avoid safety accidents, reduce losses, and effectively protect the personal safety of the operator. It is easy to operate and safe and reliable to use.

[0013] 2) The device has a simple structure, low processing and manufacturing cost, and is easy to install. It plays a certain role in warning the driver of vehicle operation. The device is applicable to all dump trucks and has a wide range of uses. Before the vehicle is ready to open the lifting mechanism, if the tilt angle between the horizontal plane of the dump truck and the ground is ≧30°, the vehicle will sound an alarm, prompting the driver that the vehicle status has exceeded the safety range and there may be a risk of rollover; installing the device does not change the original wiring harness and function of the vehicle, there is no safety hazard, it meets the vehicle technical standards, and ensures the safety of vehicle lifting.
