[0002] Unmanned mining trucks (hereinafter referred to as unmanned mining trucks) are important intelligent automated operating equipment in mining facilities. By integrating advanced technologies such as high-precision positioning, environmental perception, decision-making and planning, and vehicle control, they can achieve continuous and uninterrupted operation of mining trucks, significantly improving the efficiency, safety, and economy of mining transportation.

[0003] In the operation of unmanned mining trucks, numerous travel sensors are required to monitor the operational status of key components in real time to ensure safe and stable operations. Currently, these sensors are typically mounted using fixed brackets. However, due to structural differences between different truck models and varying spatial positions of the objects being measured, diverse requirements arise for the sensor mounting angles. Existing fixed mounting brackets have a simple structure and non-adjustable angles, making them difficult to adapt to complex and changing actual installation conditions. This results in inconvenient sensor installation, poor versatility, and may even affect the accuracy of monitoring data due to improper mounting angles.

[0004] Therefore, there is an urgent need to develop a mounting bracket with an adjustable angle to meet the different installation requirements of travel sensors for unmanned mining trucks. Utility Model Content

[0026] The following will be combined with the appendix Figures 1 to 9 The present invention will be further described below.

[0027] Example 1 like Figures 1 to 4 As shown, this embodiment provides a mounting bracket for a stroke sensor 5 on an unmanned mining truck, including a base 1 and an angle adjustment mechanism. The base 1 is used to connect the unmanned mining truck and serves as the base of the entire bracket. It is fixedly connected to a preset installation position on the unmanned mining truck body by bolts, providing stable support for the entire bracket. The angle adjustment mechanism is connected to the base 1 and is used to install the stroke sensor 5 and flexibly adjust its angle. In this embodiment, the angle adjustment mechanism specifically includes a horizontal rotation mechanism and a mounting plate 4. The mounting plate 4 is connected to the horizontal rotation mechanism and has threaded holes for installing the stroke sensor 5. Weight-reduction holes can also be provided on the base 1 to effectively reduce the overall weight of the bracket while ensuring structural strength.

[0028] Specifically, the horizontal rotation mechanism includes a turntable 2 and a locking structure. The turntable 2 is horizontally rotatably connected to the base 1, achieving 360° stepless rotation in the horizontal plane, providing ample flexibility for angle adjustment. The locking structure is used to lock the rotation angle of the turntable 2 on the base 1. After the angle adjustment is completed, the turntable 2 is firmly locked to the base 1 to prevent it from loosening during vehicle operation. As a basic and reliable implementation, the locking structure can be a bolt and nut fastening structure that passes through corresponding holes on the turntable 2 and the base 1, achieving locking through the huge frictional force generated by tightening the bolts. Another implementation is to set a radially movable pressure block or clamp on the radially outer side of the turntable 2, achieving locking by pressing the circumferential surface of the turntable 2.

[0029] In a preferred embodiment of this invention, such as Figures 1 to 4 As shown, the locking structure includes a first arc groove 1-2, a second arc groove 2-1, and a fastener 2-2. The first arc groove 1-2 is formed on the base 1 with the rotation center of the turntable 2 as the center. The second arc groove 2-1 is set on the turntable 2 at a position corresponding to the first arc groove 1-2. The fastener 2-2 passes through the first arc groove 1-2 and the second arc groove 2-1 and fastens the turntable 2 and the base 1 (the bolts are sequentially passed through the pair of overlapping arc grooves and locked by nuts).

[0030] Preferably, multiple first arc-shaped grooves 1-2 and second arc-shaped grooves 2-1 are evenly distributed around the base 1 and turntable 2, and multiple corresponding fasteners 2-2 are also provided. This combination of multiple sets of arc-shaped grooves and fasteners 2-2 forms a multi-point locking mechanism, which enhances the stability of the entire support under vibration.

[0031] In a preferred embodiment, the mounting plate 4 is fixedly connected to the top surface of the turntable 2, the length of the mounting plate 4 extends vertically, and the threaded hole horizontally penetrates the mounting plate 4. In other embodiments, the mounting plate 4 and the turntable 2 may not be perpendicular; the connection position between the two can be set to be inclined, at a specific included angle.

[0032] This embodiment achieves the function of stepless horizontal adjustment and stable locking of the stroke sensor 5 by setting up a horizontal rotation mechanism with turntable 2 and a locking structure based on arc groove as the core, and with the mounting plate 4 with mounting holes. This solves the problem of poor installation adaptability and low versatility caused by the non-adjustable angle of the existing fixed bracket.

[0033] Example 2 The similarity between this embodiment and Embodiment 1 is that both adopt a horizontal rotation mechanism. Its core components also include a base 1 and a horizontal rotation mechanism with a turntable 2, so as to realize the 360° rotation adjustment of the stroke sensor 5 in the horizontal plane.

[0034] The main difference in this embodiment lies in the different locking structures between the fixed turntable 2 and the base 1. In this embodiment, as shown... Figure 5 As shown, the locking structure employs a central shaft locking scheme. This structure includes a rotating shaft 2-3 and a locking nut 2-4. Specifically, the rotating shaft 2-3 is fixed vertically downwards at the center of the turntable 2. Correspondingly, a shaft hole 1-1 precisely mates with the rotating shaft 2-3 is provided at the center of the base 1. During installation, the rotating shaft 2-3 of the turntable 2 is inserted into the shaft hole 1-1 of the base 1 from top to bottom, allowing the turntable 2 to rotate smoothly around its central axis. To achieve locking, the end portion of the rotating shaft 2-3 extending through the shaft hole 1-1 of the base 1 is machined with external threads. After rotating the turntable 2 to the desired angle, the locking nut 2-4 is screwed onto the thread at the end of the rotating shaft 2-3 and tightened with a tool to firmly press the turntable 2 and the base 1 together, achieving locking.

[0035] The locking structure in this embodiment is simple and compact, and only requires tightening a single nut to complete the locking, making the operation extremely convenient.

[0036] Example 3 The difference between this embodiment and Embodiments 1 and 2 is that a pitch adjustment mechanism 3 is provided for mounting the travel sensor 5 and flexibly adjusting the pitch angle of the travel sensor 5.

[0037] like Figure 6 As shown, when the angle adjustment mechanism does not include the horizontal rotation mechanism but only includes the pitch adjustment mechanism 3, the pitch adjustment mechanism 3 includes a connecting rod 3-1, a slider 3-2 and an adjusting screw 3-3. The mounting plate 4 is hinged to the base 1. The two ends of the connecting rod 3-1 are respectively hinged to the mounting plate 4 and the slider 3-2. The slider 3-2 is threadedly connected to the adjusting screw 3-3. The slider 3-2 is slidably connected to the base 1. The adjusting screw 3-3 is rotatably connected to the base 1.

[0038] Working principle: When it is necessary to adjust the pitch angle of the travel sensor 5, rotate the adjusting screw 3-3, which drives the threaded slider 3-2 to slide back and forth on the base 1 along the length of the adjusting screw 3-3. The movement of the slider 3-2 pushes or pulls the mounting plate 4 through the connecting rod 3-1, causing it to rotate around the lower hinge axis, thereby precisely changing the pitch angle of the mounting plate 4 and the travel sensor 5 fixed above it.

[0039] Preferably, the base 1 is provided with an adjusting seat, and the adjusting screw 3-3 is rotatably connected to the adjusting seat. A limiting locking pin 3-4 passes through the adjusting seat, and the adjusting screw 3-3 is provided with a limiting groove corresponding to the limiting locking pin 3-4. The limiting locking pin 3-4 is provided with threads, and the adjusting seat is provided with corresponding threaded holes. When the limiting locking pin 3-4 is tightened downwards, the adjusting screw 3-3 can be pressed tight, preventing it from rotating. This prevents the adjusting screw 3-3 from rotating due to vibration during use, thereby improving the overall stability of the mounting bracket.

[0040] To facilitate the adjustment of the pitch angle, an adjustment knob 3-5 is provided at one end of the adjustment screw 3-3, and the adjustment knob 3-5 is provided with anti-slip texture on its periphery.

[0041] This embodiment achieves the stepless, precise adjustment and reliable locking of the pitch angle of the travel sensor 5 by setting up a pitch adjustment mechanism 3 consisting of a connecting rod 3-1, a slider 3-2 and an adjusting screw 3-3, and using a limit locking pin 3-4 for locking. This solves the problem that existing fixed brackets cannot adjust the angle of the travel sensor 5 in the vertical plane.

[0042] Example 4 The difference between this embodiment and Embodiments 1, 2 and 3 is that this embodiment simultaneously sets up a horizontal rotation mechanism and a pitch adjustment mechanism 3, constructing a dual-degree-of-freedom angle adjustment system, which can simultaneously realize the angle adjustment of the stroke sensor 5 in the horizontal and vertical directions.

[0043] like Figures 7 to 9 As shown, when the angle adjustment mechanism includes a horizontal rotation mechanism and a pitch adjustment mechanism 3, the pitch adjustment mechanism 3 is located on the top surface of the turntable 2 and rotates horizontally with the turntable 2. Its specific configuration is the same as in Embodiment 3. The pitch adjustment mechanism 3 includes a connecting rod 3-1, a slider 3-2, and an adjusting screw 3-3. The mounting plate 4 is hinged to the turntable 2. The two ends of the connecting rod 3-1 are respectively hinged to the mounting plate 4 and the slider 3-2. The slider 3-2 is threadedly connected to the adjusting screw 3-3, and the slider 3-2 is slidably connected to the turntable 2. The adjusting screw 3-3 is rotatably connected to the turntable 2. An adjusting seat is provided on the turntable 2, and the adjusting screw 3-3 is rotatably connected to the adjusting seat. A limiting locking pin 3-4 passes through the adjusting seat, and the adjusting screw 3-3 has a limiting groove corresponding to the limiting locking pin 3-4.

[0044] This embodiment achieves the dual functions of 360° rotation in the horizontal plane and stepless adjustment of the vertical plane pitch angle by setting up a coordinated combination of the horizontal rotation mechanism and the pitch adjustment mechanism 3, thus solving the problem that existing fixed brackets cannot meet the installation requirements of complex spaces.

[0045] In summary, this invention, by incorporating an angle adjustment mechanism, enables flexible adjustment of the installation angle of the travel sensor 5. This solves the problems of inconvenient sensor installation, poor versatility, and potential impact on the accuracy of monitoring data caused by the single structure and non-adjustable angle of existing fixed mounting brackets. The horizontal rotation mechanism and the pitch adjustment mechanism 3 allow the sensor to be adjusted at multiple angles in both the horizontal and vertical directions, thereby adapting to the structural differences of different unmanned mining truck models and the spatial position changes of the object being measured. This ensures the accuracy and stability of the sensor installation, improves the reliability of travel monitoring, and enhances the safe operation of mining equipment.

[0046] Components and principles not described in detail in this utility model can be implemented using various structures and principles known in the prior art.

[0047] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
