Description

Technical Field

[0001] The utility model relates to the technical field of engineering vehicles, in particular to a safety reminder device for a dump truck. Background Art

[0002] Dump trucks are a common means of transportation and a type of engineering vehicle. They are widely used in construction, mining, short-distance fast loading and unloading transportation and other fields. During operation, the driver needs to raise the car body to unload materials. However, in busy or careless situations, the driver may forget to lower the car body and drive away from the work site. This operational error may lead to serious safety accidents. For example, if the car body is not lowered and suddenly collides with a height-limited door or bridge while driving at high speed, it may cause harm to pedestrians and other vehicles, and may even cause a rollover accident due to the high center of gravity. Therefore, it is necessary to provide a simple and effective reminder mechanism to ensure that the driver checks whether the car body has fallen at any time before starting the vehicle or while driving.

[0003] Therefore, the problem that the inventor wants to solve is to design a device with a dual detection mechanism to detect the truck bucket, alarm if the truck bucket has not fallen, and remind the driver to reduce safety hazards. Utility Model Content

These embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0020] See also Figures 1 to 3 This is a schematic diagram of the utility model structure. Figure 1 A partial enlarged view of the tipping bucket raised in the middle. Figure 1 A partial enlarged view of the dump truck in the fallen state at point A, a safety reminder device for a dump truck, the dump truck includes a frame, a car body 6, a cab, and the vehicle's accessory units such as a battery 1 are mostly arranged in the engine room at the front of the vehicle and the inner side of the frame. The car body 6 is a dump truck car body 6, which is hinged to the frame in an articulated manner through a hydraulic cylinder.

[0021] The safety reminder device includes a mounting frame 12, which is fixed on the side end face of the frame by bolts, and the end of the mounting frame 12 extends out of the edge range of the car body 6. An articulated seat 11 is provided on the upper end face of the mounting frame 12. A connecting ear plate 9 is rotatably connected to the inner side of the articulated seat 11 through a pin shaft 10. The end of the connecting ear plate 9 is connected to a flap structure, and the flap structure includes a first flap 7 and a second flap 8. An arc transition structure is provided between the first flap 7 and the second flap 8. The angle between the first flap 7 and the second flap 8 is 130°. A spring connecting seat 14 is connected to the end face of the second flap 8 and the end face of the mounting frame 12, and a tension spring 15 is connected between the two spring connecting seats 14. Under unobstructed conditions, the second flap 8 is pulled by the tension spring 15, and the right end is lower than the left end. When the first flap 7 is squeezed, the first flap 7 and the second flap 8 rotate counterclockwise around the pin shaft 10.

[0022] A travel switch 16 is arranged on the side of the tension spring 15 and on the end face of the mounting frame 12, a position sensor 13 is arranged on the side of the articulated seat 11 and on the inner side of the mounting frame 12 through a nut, a connecting flange 4 is connected to the side end face of the carriage 6 through bolts, a pressure rod 5 is connected to the end face of the connecting flange 4, a controller 2 is arranged inside the cab, the controller 2 is electrically connected to the position sensor 13 and the travel switch 16 through wires, the controller 2 is electrically connected to the alarm 3 through wires, the alarm 3 is arranged above the controller 2, a battery 1 is arranged on the inner side of the frame, and the controller 2 is electrically connected to the battery 1 by dropping the line.

[0023] When the pressure rod 5 is not in contact with the flap and the pressure rod 5 completely leaves the flap and the second flap 8 is placed horizontally, the lower end surface of the second flap 8 presses the spring that triggers the travel switch 16, and the second flap 8 squeezes the travel switch 16, so that the travel switch 16 is triggered. The first flap 7 is tilted upward at this time and cannot be sensed by the position sensor 13. Therefore, the position sensor 13 is not triggered and the travel switch 16 is triggered. The dual signal is transmitted to the controller 2, and according to the set program, it is determined that the car 6 is in the lifted state at this time, and the controller 2 controls the alarm 3 to alarm.

[0024] The inner diameter of the arc transition structure of the flap is the same as the outer diameter of the pressure rod 5. When the pressure rod 5 drops to the lowest point, it fits with the arc transition structure. When the pressure rod 5 drops to the lowest point, the first flap 7 connected to the arc transition structure is placed horizontally. When the first flap 7 is placed horizontally, the lower end surface coincides with the sensing position of the position sensor 13. At this time, the second flap 8 is tilted because the first flap 7 is placed horizontally, and the pressure on the spring leaf of the travel switch 16 is lost, so that the travel switch 16 is reset and no longer triggered. At the same time, because the first flap 7 is placed horizontally and is in the triggering position of the position sensor 13, the position sensor 13 is triggered, and a double signal is transmitted to the controller 2. According to the set program, it is determined that the position sensor 13 is triggered and the travel switch 16 is not triggered. At this time, the car 6 is in the lowered state, and the alarm 3 is controlled to stop the alarm.

[0025] In order to better serve as a reminder to the driver, the alarm 3 further includes a built-in buzzer and a warning light arranged above the buzzer.

[0026] The utility model adopts a position sensor 13 and a travel switch 16 to form a double detection mechanism. Under normal circumstances, the travel switch is not triggered and the position sensor 13 is triggered. If one of the two conditions is missing, a buzzer alarm will be triggered in the cab and a red light will flash. The double detection mechanism detects the bucket. If the bucket does not fall, an alarm will be sounded to remind the driver, thereby reducing safety hazards.
