[0002] Open-pit mine inspections are a crucial part of mine safety management, production operations, and environmental protection, enabling the identification of safety hazards and monitoring slope stability. In particular, the emergence of intelligent mine inspection vehicles has significantly improved inspection efficiency, ensured inspection quality, and reduced labor costs. These intelligent mine inspection vehicles are equipped with sensing devices that collect environmental information during inspections. The analysis of this information by the monitoring center then determines whether any anomalies are present at the inspected location.

[0003] However, due to the complex and rugged roads in open-pit mines, the intelligent inspection vehicle will experience bumps during operation. Prolonged bumps may cause the sensing equipment installed on the vehicle to gradually loosen or even fall off, making it impossible to carry out subsequent inspection work. Utility Model Content

[0029] This disclosure provides an intelligent mining inspection vehicle and its loosening monitoring assembly. Preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit this disclosure. Furthermore, the embodiments and features described in this application can be combined with each other unless otherwise specified.

[0030] This disclosure provides a loosening monitoring assembly for use in a mining intelligent inspection vehicle, such as... Figures 1a to 1d As shown, the loosening monitoring assembly includes: assembly component 101 and monitoring component 102;

[0031] Assembly component 101 is used to fix the sensing device 103 of the intelligent mining inspection vehicle to a designated part 104 of the intelligent mining inspection vehicle, wherein the designated part 104 includes an assembly position of the equipment mounting bracket or an assembly position of the equipment mounting base of the intelligent mining inspection vehicle.

[0032] The monitoring component 102 is set at a preset position. The monitoring component 102 is used to monitor the force at the preset position in order to determine whether the sensing device 103 has become loose. The preset position includes: between the sensing device 103 and the designated part 104, or between the assembly component 101 and the sensing device 103.

[0033] Optionally, the body of the assembly component 101 can be any form of component that can be installed and function in conjunction with the sensing device 103, and this disclosure does not specifically limit its form. For example, when the sensing device 103 needs to capture environmental information from the surroundings or a distance, the assembly component 101 can be provided with adaptable through holes, etc., to meet the information capture requirements of the assembly component 101.

[0034] Optionally, the monitoring component 102 is a component capable of monitoring the force applied to a specific part, such as a micro deformation capture element (which may be based on imaging principles), a pressure capture element (such as a pressure sensing module), or a tension monitoring component.

[0035] Figure 1a An exemplary example is shown: an equipment mounting bracket 201 for a mining intelligent inspection vehicle. The designated location 104 is the assembly position 104 of the equipment mounting bracket 201, and the sensing device 103 is fixedly mounted to the assembly position 104 of the equipment mounting bracket 201. The sensing device 103 is provided with at least one mounting hole 1031. Figure 1a The sensing device 103 has three mounting holes 1031 arranged circumferentially. The device mounting bracket 201 has corresponding connecting holes at the corresponding positions of each mounting hole 1031, allowing the assembly component 101 to extend through the mounting holes 1031 and the corresponding connecting holes to fix the sensing device 103 to the designated location 104. Additionally, the device mounting bracket 201 also has assembly holes 2011 for mounting the device mounting bracket 201 to the frame of the mining intelligent inspection vehicle.

[0036] Figure 1b An exemplary schematic diagram illustrates the structure after the assembly assembly 101 (a bolt assembly in this example) is assembled with the monitoring assembly 102 (an elastic washer that mates with the bolt assembly in this example), the sensing device 103, and the equipment mounting bracket 201 through a mounting hole 1031 of the sensing device 103. Other mounting holes 1031 can also be used for assembly with corresponding bolt assemblies, but are not shown in the figure. Additionally, the monitoring assembly 102 is not shown due to the obstruction of the assembly assembly 101 at this angle.

[0037] Figure 1c and Figure 1d To be Figure 1bThe image shows a magnified view of part A in the thickness direction, specifically an assembled diagram of assembly component 101, monitoring component 102, sensing device 103, and designated part 104. It should be noted that... Figures 1a to 1d Taking assembly component 101 as an example where it is a bolted assembly (this disclosure is not limited to this), the monitoring component 102, sensing device 103, and designated part 104 are respectively provided with holes for mating with the bolted assembly; when assembly component 101 is another type of component, the monitoring component 102, sensing device 103, and designated part 104 can be mated with that other type of component without providing holes, this is just an example. The structure of the equipment mounting bracket 201 in the figure is only schematic.

[0038] like Figure 1a and Figure 1b As shown, the intelligent mining inspection vehicle can be equipped with an equipment mounting bracket 201 or an equipment mounting base, and an assembly position, i.e., a designated part 104 for mounting the sensing device 103, can be set on the equipment mounting bracket 201 or the equipment mounting base. The sensing device 103 is fixedly assembled to the designated part 104 by the assembly component 101. In order to fix the sensing device 103, the assembly component 101 needs to provide a certain force between the sensing device 103 and the designated part 104, and between the assembly component 101 and the sensing device 103. Therefore, the monitoring component 102 can be set between the sensing device 103 and the designated part 104, or between the assembly component 101 and the sensing device 103, according to actual needs, so as to monitor whether the sensing device 103 is loose.

[0039] Taking assembly component 101 as a bolt assembly as an example, the bolt assembly can fix the sensing device 103 to the designated location 104 through preload. If the force between the sensing device 103 and the designated location 104 decreases, it indicates that the sensing device 103 has become loose. Therefore, the loosening of the sensing device 103 can be monitored by monitoring the force between the sensing device 103 and the designated location 104, or the force between the assembly component 101 and the sensing device 103. Therefore, a monitoring component 102 can be installed between the sensing device 103 and the designated location 104, or between the assembly component 101 and the sensing device 103, to monitor the force at that location. That is, while the assembly component 101 fixes the sensing device 103 to the designated part, it also fixes the monitoring component 103 between the sensing device 103 and the designated part 104 or between the assembly component 101 and the sensing device 103. Once the sensing device 103 and the designated part 104 become loose, it can be detected by the monitoring component 102. Then, maintenance can be carried out before the sensing device 103 is removed from the designated part 104, thus improving work efficiency.

[0040] In yet another embodiment provided in this disclosure, such as Figure 2 As shown, the monitoring component 102 includes: an elastic pad 1021 and a pressure sensor 1022 disposed within the elastic pad 1021.

[0041] Figure 2 This is a schematic cross-sectional view of the monitoring component 102 provided in an embodiment of this disclosure. Figure 2 As shown, the pressure sensor 1022 is disposed inside the elastic pad 1021. Figure 2 The shape, size, number, position in the elastic pad 1021, and contact surface of the pressure sensor 1022 are for illustrative purposes only. They can be set according to the actual situation during implementation and are not limited here.

[0042] The installation of a pressure sensor 1022 within the elastic pad 1021 simplifies the installation of the monitoring component 102, resulting in a cleaner and more aesthetically pleasing appearance. Furthermore, the internal pressure sensor 1022 monitors the pressure at the installation location, ensuring the efficient operation of the sensing device 103. In this embodiment, the monitoring component can consist of an elastic pad and a pressure sensor housed within it. This pressure sensor is elastic, which effectively reduces the size of the monitoring component and lowers the cost of loosening monitoring while ensuring accurate monitoring data.

[0043] In another embodiment provided in this disclosure, the elastic pad 1021 is provided with a mounting groove and a pin wire channel inside;

[0044] The dimensions of the pressure sensor 1022 are adapted to the dimensions of the mounting slot and it is fixed inside the mounting slot;

[0045] The pressure sensor 1022 also has pin lines, which are led out from the pin line channel and electrically connected to the corresponding external module.

[0046] In this embodiment, when the pressure sensor 1022 is placed inside the elastic pad 1021, corresponding mounting slots can be pre-set inside the elastic pad 1021 according to the shape, size, and number of pressure sensors 1022 used, so as to more securely place the pressure sensor 1022 in the mounting slot. The mounting slot can further fix the pressure sensor 1022 in the form of a snap-fit ​​or adhesive, so as to prevent the movement of the pressure sensor 1022 from affecting the monitoring effect.

[0047] In addition, the pressure sensor 1022 also has pins, typically including power pins and signal pins. Wiring methods generally include two-wire, three-wire, four-wire, and even five-wire systems. In this embodiment, since the pressure sensor 1022 is located inside the elastic pad 1021, the pins of the pressure sensor 1022 need to be led out from inside the elastic pad 1021. To ensure that the pins are not damaged inside the elastic pad 1021, a corresponding pin channel can be provided for each pin within the elastic pad 1021. In practice, the pin channels can be set inside the elastic pad 1021 according to the number of pins of the pressure sensor 1022 used and the wiring layout, so that the pins can be led out of the elastic pad from the pin channels and electrically connected to the corresponding external module. For example, the power line can be connected to a provided power source, and the signal line can be connected to a signal receiving device; details will not be elaborated here.

[0048] In yet another embodiment provided in this disclosure, the pressure sensor 1022 is elastic.

[0049] In this embodiment, the elastic effect of the elastic pad 1021 can improve the tightness of the connection by adjusting the pressure with the contact surface. For example, when the assembly component 101 is subjected to vibration or external force, the elastic pad 1021 will automatically adjust to ensure a tight fit with the contact surface. An elastic pressure sensor 1022 is provided inside the elastic pad 1021. When the assembly component 101 is subjected to vibration or external force, the pressure sensor 1022 can deform along with the elastic pad 1021, thereby detecting changes in the external force.

[0050] After initial installation, the elastic pad 1021 and pressure sensor 1022 are at their optimal tightening point. Under the pressure of the assembly component 101, the elastic pad 1021 and pressure sensor 1022 undergo a certain deformation, detecting the force at their respective locations. When the monitoring component 102 is installed between the sensing device 103 and the designated location 104, if the sensing device 103 becomes loose, the deformation between the elastic pad 1021 and pressure sensor 1022 decreases. The extent of this decrease in deformation determines whether the sensing device 103 has become loose. Conversely, when the monitoring component 102 is installed between the assembly component 101 and the sensing device 103, if the sensing device 103 becomes loose, the sensing device 103 causes the elastic pad 1021 to continuously compress the pressure sensor 1022, resulting in a greater deformation between the elastic pad 1021 and pressure sensor 1022. The extent of this increased deformation determines whether the sensing device 103 has become loose.

[0051] In another embodiment provided in this disclosure, the elastic pad 1021 includes an elastic gasket, and the assembly assembly 101 includes a snap-fit ​​assembly or a clamp assembly; or,

[0052] The elastic washer 1021 includes an elastic gasket, and the assembly 101 includes a bolt assembly; wherein the inner diameter of the elastic washer is adapted to the stud size of the bolt assembly.

[0053] In this embodiment, the shape of the elastic pad 1021 can be configured to match the assembly form of the assembly assembly 101, including an elastic gasket or an elastic washer. When the assembly assembly 101 uses a snap-fit ​​component (such as...) Figure 3 (as shown) or fixture assembly (such as Figure 4 In the case shown), the elastic pad 1021 can be an elastic washer, and when the assembly 101 uses a bolt assembly (such as... Figures 1a to 1d , Figure 5 In the case shown), the elastic washer 1021 can be an elastic washer, that is, a hole is provided on the elastic washer, and the size of the hole (the inner diameter of the elastic washer) is adapted to the stud size of the bolt assembly (the hole diameter is greater than or equal to the stud diameter).

[0054] It should be noted that, Figure 3 and Figure 4 The figures show top views of the assembly assembly 101 using a snap-fit ​​assembly and a clamp assembly, with the elastic pad 1021 positioned between the sensing device 103 and the designated location 104. The case where the elastic pad 1021 is positioned between the assembly assembly 101 and the sensing device 103 is not shown. Figure 5 This is a schematic diagram of a bolt assembly and a flexible washer. The shapes of all components and equipment in the diagram are for illustrative purposes only and are not intended to limit this disclosure.

[0055] In addition, when the elastic pad 1021 is in the form of an elastic washer, the mounting groove and pin wire channel of the pressure sensor 1022 located inside the elastic washer need to be set to avoid the hollow parts, which will not be described in detail here.

[0056] In another embodiment provided in this disclosure, the pressure sensor 1022 includes: a thin-film pressure sensor and / or a microelectromechanical system (MEMS) pressure sensor.

[0057] In this embodiment of the disclosure, since the thin-film pressure sensor and the MEMS pressure sensor are small in size and highly sensitive, they can be disposed in the elastic pad 1021.

[0058] In another embodiment provided in this disclosure, the elastic pad 1021 is made of rubber or metal.

[0059] In another embodiment provided in this disclosure, at least one side of the elastic pad 1021 is provided with a rough texture or a pattern.

[0060] In this embodiment of the disclosure, in order to increase the friction between the elastic pad 1021 and the contact surface and improve the fastening effect, at least one side of the elastic pad 1021 can be set to a rough shape or a preset pattern.

[0061] This disclosure provides a mine intelligent inspection vehicle, which is equipped with a sensing device 103 and a device mounting bracket or mounting base for mounting the sensing device; the mine intelligent inspection vehicle includes a loosening monitoring assembly as described in any of the above embodiments.

[0062] In another embodiment provided in this disclosure, the intelligent mining inspection vehicle further includes:

[0063] The output device is used to output the monitoring results of the force at the preset position.

[0064] In this embodiment of the disclosure, an output device can be installed on the intelligent mining inspection vehicle. The output device may include an audio and video output device, such as a display that displays the monitoring results of the force at a preset position in real time, or a buzzer.

[0065] Optionally, it may also be equipped with an output device to communicate with the intelligent mining inspection vehicle. For example, the output device may be a remote user terminal device.

[0066] In another embodiment provided in this disclosure, the sensing device 103 can be any device capable of sensing, locating, and identifying target objects. Optionally, the sensing device 103 may include at least one of the following: lidar, image acquisition equipment, millimeter-wave radar. Optionally, the sensing device 103 may also be a positioning device, heading monitoring device, etc., on an intelligent inspection vehicle.

[0067] Those skilled in the art will understand that the accompanying drawings are merely illustrative of a preferred embodiment, and the devices or components in the drawings are not necessarily essential for implementing this disclosure.

[0068] Obviously, those skilled in the art can make various modifications and variations to this disclosure without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims of this disclosure and their equivalents, this disclosure is also intended to include such modifications and variations.
