Description

Technical Field

[0001] This utility model belongs to the field of unmanned mining dump trucks, specifically relating to an antenna bracket for a mining dump truck. Background Technology

[0002] Mining dump trucks are core transportation equipment in open-pit mining, used for transporting materials such as ore and earth. The harsh mining environment makes traditional manned driving inefficient and unsafe, while the widespread adoption of autonomous driving technology has driven the automation upgrade of mining dump trucks. In autonomous driving systems, inertial navigation systems (INS) serve as the core positioning device, providing vehicles with high-precision position, speed, and attitude information.

[0003] In existing technologies, the antenna of the inertial navigation system must be installed in an open area above the top edge of the vehicle to reduce signal interference, so the antenna is usually installed near the driver's cab. However, this location lacks protection, making it vulnerable to being hit by falling rocks from the electric shovel used for loading ore during the loading process, which affects the stability of the unmanned driving system.

[0004] To address the aforementioned issues, it was proposed to install the antenna at the rear of the mining dump truck to reduce the risk of damage from falling objects. However, this installation method presents new challenges during unloading: the rear of the dump truck needs to be tilted to dump the material, placing higher demands on the antenna's installation position and stability. Improper installation may result in vibration, tilting, or obstruction during unloading, further affecting signal reception.

[0005] There is an urgent need for a new antenna installation scheme that can ensure the antenna signal reception capability while keeping it stable during the unloading process, thereby improving the positioning accuracy and operational stability of the autonomous driving system.

[0022] like Figure 1 The diagram shown is a structural schematic of the bracket assembly 1 in this utility model; as shown... Figure 2 The diagram shown is a structural schematic of the antenna bracket for a mining dump truck in this utility model.

[0023] The bracket assembly 1 adopts a lightweight frame structure, including: side rods 11 and diagonal ribs 12. Multiple side rods 11 are connected end to end. The diagonal ribs 12 are located inside the side rods 11. The two ends of the diagonal ribs 12 are connected to two different side rods 11 respectively. An assembly connection end 13 is provided at the connection point of two adjacent side rods 11. The assembly connection end 13 is located at the bottom of the bracket assembly 1.

[0024] The diagonal ribs 12 are arranged at a certain angle to form a stable support structure, which ensures the strength of the bracket assembly 1, while also ensuring that the overall weight is not too heavy, so that the bracket assembly 1 can rotate flexibly and easily.

[0025] The antenna bracket for a mining dump truck includes: bracket assembly 1, vertical rod 2, support base 3, transition base 4, buffer base 5, buffer pad 6, and antenna mounting bracket 7; the lower end of the vertical rod 2 is hinged to the support base 3, and the upper end of the vertical rod 2 is hinged to the assembly connection end 13.

[0026] The vertical rod 2 has vertical rod through holes at both ends, and the assembly connection end 13 has an end through hole. The pin 8 passes through the vertical rod through hole and the end through hole, and the upper end of the vertical rod 2 is hinged to the assembly connection end 13.

[0027] The support base 3 has a first top plate and multiple support base connecting through holes on its top. The first top plate has a first top plate through hole, and the multiple support base connecting through holes are located on the outside of the first top plate. Fastening bolts are installed in the support base connecting through holes. The pin 8 passes through the vertical rod through hole and the first top plate through hole, hinged to the lower end of the vertical rod 2 and the support base 3. The support base 3 is connected to the small platform of the rear wheel cover of the dump truck by fastening bolts.

[0028] The transition base 4 is hinged at the connection point of the two side rods 11. A connecting plate with through holes is provided at the connection point. The transition base 4 is located at the bottom of the support assembly 1. The transition base 4 has a second top plate and multiple transition base connecting through holes located on the outside of the second top plate. The second top plate has second top plate through holes, and fastening bolts are installed in the transition base connecting through holes. The pin 8 passes through the second top plate through holes and the connecting plate through holes, hinged to the bottom of the transition base 4 and the support assembly 1. The transition base 4 is connected to the bottom of the dump truck body by fastening bolts. The transition base 4 and the assembly connection end 13 are located on both sides of the support assembly 1.

[0029] The buffer base 5 is provided with multiple buffer base connection through holes and threaded holes, and fastening bolts are installed in the buffer base connection through holes. The U-shaped plate is provided with a U-shaped groove, and a U-shaped plate through hole is provided on the outside of the U-shaped groove.

[0030] The buffer pad 6 is provided with a buffer pad through hole. The buffer pad 6 is located between the side rod 11 and the buffer base 5. The side rod 11 is inserted into the U-shaped groove.

[0031] The antenna mounting bracket 7 is welded to the side rod 11. The antenna mounting bracket 7 is located at the top of the bracket assembly 1 and is used to mount the antenna.

[0032] like Figure 3 The diagram shown is a schematic representation of the working principle of the antenna bracket for a mining dump truck in this utility model; as shown... Figure 4 The diagram shown is a schematic representation of the installation positions of the buffer base 5 and the buffer pad 6 in this utility model.

[0033] The buffer base 5 is fixed to one side of the carriage 9 by fastening bolts. The buffer pad 6 is installed on the buffer base 5 to provide support when the antenna bracket is lowered and to absorb the vibration generated during the journey, so as to ensure stability.

[0034] The vertical rod 2 and the bracket assembly 1 can rotate around the pin 8. When the mine car is unloading, the car body 9 flips over, and the antenna mounting bracket 7 always remains horizontal.

[0035] The antenna bracket for the mining dump truck, through its multi-axis connection design, can automatically adjust its angle when the truck bed 9 tilts, ensuring the antenna remains horizontal and preventing tilting or shifting due to the truck bed 9's tilt. The buffer pad 6 and buffer base 5 effectively cushion vibrations during vehicle movement, improving antenna stability. This solves the problem of inaccurate positioning caused by inertial navigation antennas located at the rear of the mining truck tilting, while also reducing the impact of vibration on the antenna, providing a reliable guarantee for high-precision positioning of unmanned mining dump trucks.
