Description

Technical Field

[0001] The present invention relates to the field of driverless open-pit mining trucks, and particularly to a shock-absorbing antenna bracket suitable for driverless open-pit mining trucks. Background Art

[0002] Open-pit mining is a process of removing the overburden on the ore body to obtain the required minerals. When moving the overburden and the required minerals, trucks are usually needed for transportation.

[0003] For a long time, there have been three major pain points in mining area transportation. The first pain point is that due to the harsh mining area environment, the aging of drivers is serious, the willingness of young drivers to work is low, it is difficult to recruit workers and manage them, and the labor costs are increasing year by year. The second pain point is that the operating levels of drivers vary, and there are large differences in vehicle dispatching levels among different mines, so there is great room for efficiency improvement. The third pain point is that the mining trucks are large in size and have many blind spots, so drivers are prone to fatigue during operation, and production safety accidents often occur.

[0004] Through digital technology and optimized management, driverless operation reduces costs such as vehicle maintenance, high fuel consumption, and tire damage caused by non-standard operations, which is conducive to further improving the enterprise benefit level, helps to avoid personnel injury accidents, and truly realizes the essential safety of production operations.

[0005] To achieve driverless operation of open-pit mining trucks, it is necessary to install a wireless communication antenna and a Beidou positioning antenna on the truck. To ensure the communication efficiency and positioning accuracy, the wireless communication antenna and the Beidou positioning antenna cannot be blocked. Therefore, when installing the wireless communication antenna and the Beidou positioning antenna, long poles are used to hold the two antennas high above the open-pit mining truck.

[0006] However, due to the uncontrollable open-air environment and the uneven ground of the mine as a whole, the open-pit mining truck will be subjected to large vibrations during moving operation, and the moving speed and direction of the truck cannot always remain consistent, resulting in irregular swinging of the antenna, which affects the service life of the antenna, the positioning accuracy, and the driverless effect of the truck. Summary of the Invention

[0007] Aiming at the drawback that the antenna held by a long pole will swing irregularly during the driverless operation of the current open-pit mining truck, the present invention proposes a shock-absorbing antenna bracket suitable for driverless open-pit mining trucks.

[0008] The technical solution of the present invention is as follows: The mounting plate is connected to the support rod, the upper inclined rod, and the lower inclined rod through spherical joint bearings.

[0009] The positions of the three spherical joint bearings installed on the mounting plate are not on a straight line; the three spherical joint bearings are arranged in a triangular pattern within the plane of the mounting plate, and this triangle can be one of an acute triangle, a right triangle, or an obtuse triangle.

[0010] The upper slider and the lower slider are sleeved on the support rod. The upper slider is equipped with an upper locking bolt, and the lower slider is equipped with a lower locking bolt. When the upper locking bolt is loosened, the upper slider can slide on the support rod; when the upper locking bolt is tightened, the relative position of the upper slider and the support rod is fixed. When the lower locking bolt is loosened, the lower slider can slide on the support rod; when the lower locking bolt is tightened, the relative position of the lower slider and the support rod is fixed.

[0011] The upper slider is connected to the upper inclined rod, and the lower slider is connected to the lower inclined rod. When the upper slider and the lower slider are in appropriate positions on the support rod, the upper locking bolt and the lower locking bolt are tightened respectively, and the relative position of the support rod and the mounting plate can be fixed.

[0012] At the upper end of the support rod, a cavity is installed. Inside the internal cavity of the cavity, a pendulum ball is connected through an upper spring and a lower spring. Due to the elasticity of the upper spring and the lower spring, the pendulum ball can make appropriate displacements and reciprocating motions within the internal cavity of the cavity.

[0013] Various antennas can be installed on the outer side of the upper end of the cavity.

[0014] Advantageous effects: When the device described in the present invention is installed on a truck in an open-pit mine, the mounting plate can be installed at an appropriate position on the truck according to the actual situation without having to ensure the horizontality of the mounting plate. By adjusting the positions of the upper slider and the lower slider on the support rod and fixing them, the support rod can be made vertical, or tilted at a certain angle as needed. The antenna support described in the present invention can be generally applicable to various trucks traveling in open-pit mines.

[0015] The antenna support has good vibration damping effects. Especially when the truck is driving automatically without a driver on the uneven road surface in the open-pit mine, due to the bumps, the antenna keeps shaking. Due to inertia, the pendulum ball of the present invention will play an obvious vibration damping role through the action of the upper spring and the lower spring. Description of the drawings
