Description

Technical Field

[0001] This utility model belongs to the field of mining transportation equipment, specifically relating to a lidar installation device for unmanned off-highway mining trucks. Background Technology

[0002] Off-highway mining dump trucks (referred to as mining trucks) are a type of mining equipment, mainly used for transporting ore and mineral materials in large open-pit mines. Due to their advantages such as good operational mobility, high speed, and strong climbing ability, off-highway mining dump trucks have become the main transport tool in open-pit mines. Driverless mining trucks are a new type of off-highway mining dump truck, enabling fully unmanned continuous operation to improve mine production safety and efficiency, and reduce operating costs, thus having broad application prospects.

[0003] Environmental perception systems for unmanned off-highway mining trucks typically use lidar. However, the presence of falling rocks and flying debris during operation can cause mechanical damage to lidar. The harsh operating environment of unmanned mining trucks, with dust, rain, and snow affecting their normal operation, can also damage lidar or shorten its lifespan. Furthermore, the unpaved roads subjected to significant vibrations during operation can also damage lidar or shorten its lifespan. Finally, the minimum operating temperature for lidar is typically around -20°C; operating unmanned mining trucks in frigid conditions can cause lidar malfunctions. Utility Model Content

[0004] The purpose of this invention is to provide a lidar installation device for unmanned off-highway mining trucks, which can effectively protect the lidar and extend its service life.

[0005] To achieve the above objectives, the technical solution used in this utility model is as follows:

[0006] The unmanned off-highway mining truck lidar installation device includes: a protective cover, a heating device, a vibration damping base, and a light-transmitting cover. The protective cover is a box structure with an open front end. The light-transmitting cover is connected to the light-transmitting cover and is set at the opening. The light-transmitting cover is made of transparent material. The protective cover and the light-transmitting cover are combined to form a sealed space. The heating device and the vibration damping base are set inside the protective cover. The vibration damping base is fixed to the bottom of the inner wall, and the heating device is connected to the side of the inner wall.

[0007] Furthermore, the protective cover 1 has a first mounting interface at the bottom and a second mounting interface on the side. The vibration damping base has a base through hole. The vibration damping base is connected to the first mounting interface, and the heating device is connected to the second mounting interface.

[0008] Furthermore, the protective cover is made of steel plate, and the vibration damping base is made of rubber vibration damping material.

[0009] Furthermore, the light-transmitting cover is a semi-circular arc-shaped plate made of plexiglass.

[0010] Furthermore, the light-transmitting cover is adhered to the opening at the front end of the protective cover.

[0011] Furthermore, a sealing ring is provided at the opening, and the light-transmitting cover is connected to the opening by bolts.

[0012] Furthermore, the lidar is connected to the vibration damping base, and the lidar's signal line and power line are led out through the first mounting interface and the base through hole.
