Description
Technical Field
[0001] The utility model relates to the technical field of open-pit mine falling-rock prevention, and particularly relates to a falling-rock prevention driving device for mining trucks. Background Art
[0002] An open-pit mine strips the overlying soil and surrounding rock covering the ore body and its surroundings, transports the waste rock to the waste dump, and directly extracts the ore from the exposed ore body. Therefore, during the exploitation process of an open-pit mine, the stability of the slope is an important issue. The falling rocks on the slope will not only directly affect the mining operation but also endanger the lives of the staff. Therefore, it is very necessary to take protective measures against the falling rocks on the slope of the open-pit mine.
[0003] Regarding the problem of falling rocks in mines such as sand and gravel aggregate mines, at present, the method of installing falling-rock protection nets is mostly used to block the falling rocks from falling onto the road surface. However, with the exploitation of the mine, the protection net needs to be continuously adjusted. Moreover, there is still a risk that some crushed stones slipping through the meshes of the protection net will fall onto the mining truck. Limited by the driver's line of sight or the fact that detectors such as cameras cannot capture the falling rocks directly above the vehicle, the vehicle cannot make an emergency evasion, which is likely to cause damage to the front windshield or other vulnerable positions of the cab. At the same time, in the existing technology, the probability of the falling rock hitting the vulnerable part of the cab is often reduced by increasing the length of the cab brim. However, this method belongs to a passive protection measure, which can only withstand the damage caused by the falling rock by using the structural strength of the vehicle body and cannot avoid the falling rock, undoubtedly increasing the material cost and the vehicle weight of the whole vehicle.
[0004] It can be seen that there are still certain defects in the existing technology. Content of the Utility Model

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific implementation manners disclosed below.
[0031] As Figure 1 shown, the present application provides an anti-rockfall mining truck driving device, which mainly includes a single vehicle rockfall monitoring component 2, a single vehicle driving monitoring component 3 and a control unit 1; the single vehicle rockfall monitoring component 2 includes a long-range monitoring module 21 and a short-range monitoring module 22 arranged on the mining truck. The long-range monitoring module 21 is used to monitor the rockfalls in the long-range area around the mining truck and output corresponding rockfall information, and the short-range monitoring module 22 is used to monitor the rockfalls in the short-range area around the mining truck and output corresponding rockfall information; the single vehicle driving monitoring component 3 includes a distance monitoring module 31, and the distance monitoring module 31 is used to monitor the distance between the mining truck and the vehicle in front and / or the vehicle behind and output corresponding distance information; the control unit 1 is respectively connected to the single vehicle rockfall monitoring component 2 and the single vehicle driving monitoring component 3, and includes a control module 11 and a vehicle-to-vehicle communication module 12; the vehicle-to-vehicle communication module 12 is arranged on the mining truck and is used for communication between mining trucks and transmitting the rockfall information and distance information to the control module 11. The control unit 1 is used to receive the rockfall information and distance information and control the mining truck to accelerate urgently or brake urgently according to the rockfall information and distance information. Preferably, the rockfall information in the above solution includes rockfall position information, rockfall speed information, and rockfall acceleration information. Through the above information, the control module 11 can judge the moving path of the rockfall and the falling area of the rockfall.
[0032] As a preferred implementation manner of the present application, referring to Figure 1As shown in the figure, the single-vehicle driving monitoring component 3 further includes a speed monitoring module 32 and a position monitoring module 33 arranged on the mining truck. The speed monitoring module 32 is used to monitor the speed of the mining truck and output corresponding speed information, and the position monitoring module 33 is used to monitor the position of the mining truck and output corresponding position information. In the actual application process, after the single-vehicle rockfall monitoring component 2 on a single mining truck monitors the above rockfall information, it can transmit the above rockfall information to the mining trucks close to the rockfall dropping area through the vehicle-to-vehicle communication module 12. At the same time, the control module 11 combines the above rockfall information, the distance information between the mining trucks, the position information and speed information of the mining truck itself to control the mining trucks close to and within the rockfall dropping area to perform emergency acceleration or emergency braking within a safe range to avoid rockfalls.
[0033] In the above solution, the setting of the single-vehicle rockfall monitoring component 2 can effectively monitor the environment around the mining truck, so that the mining truck can easily discover the rockfall danger in time. And the setting of the vehicle-to-vehicle communication module 12 enables the real-time sharing of rockfall information among the mining trucks, so as to avoid deviations or omissions in rockfall monitoring caused by insufficient coverage of the single-vehicle monitoring perspective, greatly improving the effect and efficiency of the mining truck's anti-rockfall ability. And through the setting of the single-vehicle driving monitoring component 3, the actual driving information of the single mining truck can be accurately grasped, and then the driving state of the single mining truck and / or the mining truck fleet can be more precisely controlled by combining with the rockfall information, avoiding collisions between the mining truck and the vehicles in front and behind or other surrounding obstacles during the process of avoiding rockfalls, resulting in vehicle damage, and reducing the safety risks brought by the emergency actions of avoiding rockfalls while ensuring successful avoidance of rockfalls.
[0034] As a preferred embodiment of the present application, referring to Figure 1 As shown in the figure, the long-range monitoring module 21 includes at least one long-range vision sensing device 211, and the long-range vision sensing device 211 is arranged at the front of the mining truck body for collecting and outputting rockfall information in the forward direction of the mining truck; the short-range monitoring module 22 includes at least two short-range vision sensing devices 221, and the two short-range vision sensing devices 221 are arranged on both sides of the mining truck body for collecting and outputting rockfall information on both sides of the forward direction of the mining truck.

The monitoring and protection component includes a plurality of protective covers disposed on the body of the mining truck. The long-range monitoring module 21, the short-range monitoring module 22, and the distance monitoring module 31 are all disposed in the protective covers, so as to provide effective protection for the long-range monitoring module 21, the short-range monitoring module 22, and the distance monitoring module 31, and avoid damage to the long-range monitoring module 21, the short-range monitoring module 22, and the distance monitoring module 31 caused by dust and flying gravel generated during driving.
[0038] In one example, the above protective cover includes a visual protective cover and a radar protective cover.
