Description

Technical Field

[0001] The present invention relates to the field of driverless open-pit mining trucks, and particularly to a driverless antenna support device for open-pit mining trucks with adjustable shock absorption effect. 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 operation levels of drivers vary, and there are large differences in vehicle scheduling levels among different mines, so there is a large room for efficiency improvement. The third pain point is that 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 personal injury accidents, and truly realizes the essential safety of production operations.

[0005] To achieve driverless operation of open-pit mining trucks, wireless communication antennas and Beidou positioning antennas need to be installed on the trucks. To ensure the efficiency of communication and the accuracy of positioning, the wireless communication antennas and Beidou positioning antennas cannot be blocked. Therefore, when installing the wireless communication antennas and Beidou positioning antennas, 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 overall ground of the mine, 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.

[0007] In some cases, antenna supports with certain shock absorption effects are used to alleviate this problem. However, due to the often-incomplete identity of the height of the long pole and the weight of the antenna, the antenna supports with shock absorption effects often fail to achieve the best shock absorption effect. And to achieve the best shock absorption effect, customization is required. Once the antenna is repaired or replaced, and its weight changes, the shock absorption effect of the original antenna support will be greatly reduced and cannot meet the new shock absorption requirements. Summary of the Invention

[0008] Aiming at the drawback that the antenna bracket with vibration damping effect in the current open-pit mine truck cannot adapt to various antennas to achieve the best vibration damping effect during driverless operation, the present invention proposes an antenna bracket device for driverless open-pit mine trucks with adjustable vibration damping effect.

[0009] The technical solution of the present invention is as follows: Inside the inner cavity of the cavity (3), it is connected to the pendulum ball (5) through the upper spring (2) and the lower spring (6). Due to the elasticity of the upper spring (2) and the lower spring (6), the pendulum ball (5) can make appropriate displacements and reciprocating motions inside the inner cavity of the cavity (3).

[0010] The pendulum ball (5) is a hollow sphere inside, and a screw cap (4) is provided. When the screw cap (4) is unscrewed, the overall weight of the pendulum ball (5) can be adjusted by placing objects of different masses inside the pendulum ball (5).

[0011] On both sides of the cavity (3), several long holes are opened opposite to each other.

[0012] The locking bar A (8) and the locking bar B (9) pass through the long holes on both sides of the cavity (3) and enter the inside of the cavity (3).

[0013] A flared notch is opened in the middle of the locking bar A (8), and a flared notch is opened in the middle of the locking bar B (9); A rectangular notch is opened on one side of the locking bar A (8); on the other side of the locking bar A (8), there is a vertical edge with a rectangular notch, and a set screw (10) is provided; On one side of the locking bar B (9), there is a vertical edge with a rectangular notch, and a set screw (10) is provided; on the other side of the locking bar B (9), a rectangular notch is opened.

[0014] The locking bar A (8) and the locking bar B (9) cooperate with each other as a group. Through the mutual engagement of the rectangular notches of the locking bar A (8) and the locking bar B (9), and fixed by the set screw (10), a locking bar combination is formed.

[0015] A vertically penetrating hole is left in the middle of the formed locking bar combination; the distance between the vertical edges on both sides of the formed locking bar combination is equal to the external dimension of the cavity (3).

[0016] The locking bar A (8) and the locking bar B (9) respectively pass the end without a vertical edge through the long holes at the opposite positions on both sides of the cavity (3), enter the cavity (3), and then continue to extend out from the opposite long holes. After the hole in the middle of the locking bar combination just clamps a certain wire diameter of the upper spring (2) or the lower spring (6), the relative positions of the locking bar A (8) and the locking bar B (9) are fixed by the set screw (10). At this time, the vertical edges on both sides of the locking bar combination just clamp the cavity (3).

[0017] The locking bar A (8) and the locking bar B (9) pass through the long holes at the relative positions on both sides of the cavity (3) and clamp a certain wire diameter of the upper spring (2) or the lower spring (6). When the locking bar A (8) and the locking bar B (9) pass through the long holes at different heights, the effect of adjusting the effective number of turns of the upper spring (2) or the lower spring (6) is achieved, and thus the elastic coefficient of the upper spring (2) or the lower spring (6) is adjusted.

[0018] In specific practical applications, the elastic coefficient of the upper spring (2) or the lower spring (6) can be adjusted individually through a set of locking bar combinations, or two sets of locking bar combinations can be used to adjust the elastic coefficients of the upper spring (2) and the lower spring (6) simultaneously.

[0019] Beneficial effects: The device described in the present invention has a good vibration damping effect. Especially when the truck is driving automatically on the uneven road surface of 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 effect through the action of the upper spring and the lower spring.

[0020] When this device is installed on different open-pit mine trucks and used, according to specific application scenarios, such as the height of the long rod, the weight of the antenna, the average speed during the stable operation of the truck, etc., by adjusting the elastic coefficients of the upper spring (2) and the lower spring (6), and adjusting the overall weight of the pendulum ball (5), the best vibration damping effect on the antenna swing can be achieved.

[0021] And when the antenna is repaired or replaced, and its weight changes, the aforementioned adjustment method can also be used to make the entire system reach the best vibration damping effect on the antenna swing again, without having to replace the vibration damping device, reducing labor and material costs.

Detailed implementation mode

[0023] The technical solution of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments that can be implemented by the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention.

[0024] According to Figure 1 shown: The top of the long rod (11) is provided with a cavity (3), and the top of the cavity (3) is provided with a columnar antenna (1) and a mushroom antenna (7).

[0025] Inside the internal cavity of the cavity (3), it is connected to the pendulum ball (5) through the upper spring (2) and the lower spring (6). Due to the elasticity of the upper spring (2) and the lower spring (6), the pendulum ball (5) can make appropriate displacements and reciprocating motions in the internal cavity of the cavity (3).

[0026] The pendulum ball (5) is a hollow sphere inside and is provided with a rotary cover (4). When the rotary cover (4) is unscrewed, the overall weight of the pendulum ball (5) can be adjusted by placing objects of different masses inside the pendulum ball (5).

[0027] According to Figure 2 shown: On both sides of the cavity (3), several long holes are opened opposite to each other.

[0028] According to Figure 1 , Figure 2 shown: The locking bar A (8) and the locking bar B (9) pass through the long holes on both sides of the cavity (3) and enter the inside of the cavity (3).

[0029] According to Figure 3 , Figure 4 , Figure 6 , Figure 7 shown: The middle of the locking bar A (8) is provided with a flared notch, and the middle of the locking bar B (9) is provided with a flared notch; One side of the locking bar A (8) is provided with a rectangular notch; the other side of the locking bar A (8) is provided with a vertical edge, and a rectangular notch is opened on the vertical edge, and a setscrew (10) is provided; One side of the locking bar B (9) is provided with a vertical edge, and a rectangular notch is opened on the vertical edge, and a setscrew (10) is provided; the other side of the locking bar B (9) is provided with a rectangular notch.

[0030] According to Figure 5 、 Figure 8 shown as follows: The locking bar A (8) and the locking bar B (9) cooperate with each other as a group. The rectangular notches of the locking bar A (8) and the locking bar B (9) are engaged with each other and fixed by the setscrew (10) to form a locking bar combination.

[0031] A vertically penetrating cavity is left in the middle of the formed locking bar combination; the distance between the vertical sides on both sides of the formed locking bar combination is equal to the external dimension of the cavity (3).

[0032] The specific usage method of this device is as follows: The locking bar A (8) and the locking bar B (9) respectively pass the ends without vertical sides through the long holes at the opposite positions on both sides of the cavity (3). After entering the cavity (3), they continue to extend from the opposite long holes, and when the cavity in the middle of the locking bar combination just clamps a certain wire diameter of the upper spring (2) or the lower spring (6), the relative positions of the locking bar A (8) and the locking bar B (9) are fixed by the setscrew (10). At this time, the vertical sides on both sides of the locking bar combination just clamp the cavity (3).

[0033] The elastic coefficient k of the spring is related to the diameter of the spring, the wire diameter of the spring, the material of the spring, and the number of active turns of the spring. The specific relationships are as follows: 1. Inversely proportional to the diameter of the spring coil; 2. Directly proportional to the fourth power of the wire diameter of the spring; 3. Directly proportional to the elastic modulus of the material of the spring; 4. Inversely proportional to the number of active turns of the spring.

[0034] By passing the locking bar A (8) and the locking bar B (9) through the long holes at different relative positions on both sides of the cavity (3) and clamping a certain wire diameter of the upper spring (2) or the lower spring (6), the effect of adjusting the number of active turns of the upper spring (2) or the lower spring (6) is achieved, and thus the elastic coefficient of the upper spring (2) or the lower spring (6) is adjusted.

[0035] In specific practical applications, the elastic coefficient of the upper spring (2) or the lower spring (6) can be adjusted separately by a set of locking bar combinations, or the elastic coefficients of the upper spring (2) and the lower spring (6) can be adjusted simultaneously by using two sets of locking bar combinations.

[0036] For the convenience of description, the present invention only introduces the adjustment of the elastic coefficient of the upper spring (2) separately by using a set of locking bar combinations, but it does not affect the realization of the other two cases of "adjusting the elastic coefficient of the lower spring (6) separately" and "adjusting the elastic coefficients of the upper spring (2) and the lower spring (6) simultaneously".

[0037] When actually in use, according to specific application scenarios, such as different states like the height of the long rod, the weight of the antenna, and the average speed during the stable operation of the truck, the method of adjusting the elastic coefficients of the upper spring (2) and the lower spring (6) and adjusting the overall weight of the pendulum ball (5) can be used to achieve the best shock absorption effect on the antenna swing.

[0038] The mushroom antenna (7) is a Beidou positioning antenna.

[0039] The columnar antenna (1) is a wireless communication antenna.
