DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The tunnel surrounding rock morphology collection device for surrounding rock classification includes a moving component, a lifting component, a collection component and a protection component. The moving component includes a trolley 1, a transmission wheel 2 and a crawler 3. The trolley 1 is symmetrically provided with a plurality of transmission wheels 2 on both sides. The plurality of transmission wheels 2 on the same side are sleeved on the outer sides with the crawler 3. The lifting component includes a cover 4, a motor 5, a worm wheel 6, a worm 7 and a screw 8. The trolley 1 is provided with a cover 4. The cover 4 is provided with a worm 7 and two groups of worm wheels 6. The worm 7 is meshed with the two groups of worm gears 6, the screw 8 passes through the cover body 4 below and is connected to the center of the worm gear 6, the acquisition component includes a bottom plate 9, a support plate 10, a top plate 11, a shell 12 and a camera 13, the bottom plate 9 is provided with two groups of screw holes adapted to the screw 8, the top plate 11 is further provided on one side above the bottom plate 9, the shell 12 is further provided on the top plate 11, the shell 12 is provided with a camera 13, and the trolley 1 is also provided with a protective component for protecting the shell 12.

[0027] The trolley 1 in the mobile assembly serves as the bearing base of the entire device. The symmetrically arranged groups of transmission wheels 2 on the left and right sides and the crawler belt 3 sleeved on the outside of the transmission wheel 2 on the same side constitute the mobile mechanism of the device. The transmission wheel 2 rotates under the drive of a power source (such as a motor 5, etc., and a corresponding driving device can be configured according to the actual design situation to drive the transmission wheel 2 to rotate). Since there is friction between the crawler belt 3 and the transmission wheel 2 and the crawler belt 3 is a continuous ring structure, the rotation of the transmission wheel 2 will drive the crawler belt 3 to move synchronously, thereby enabling the entire device to move;

[0028] In the complex terrain environment of the tunnel, the crawler 3 can evenly distribute the weight of the device on the ground with its large ground contact area. When encountering uneven ground, the crawler 3 can adapt to the ups and downs of the ground through its own deformation to prevent the device from sinking or being unable to move due to excessive local force; when passing through areas with a small amount of water, mud or gravel, the crawler 3 can still maintain good grip to prevent slipping, ensuring that the device can move smoothly and flexibly along the predetermined route to the potential tunnel route area, providing reliable mobility for the subsequent collection of surrounding rock morphology data, and facilitating the exploration of surrounding rocks at different locations;

[0029] The motor 5 (servo motor 5) in the lifting assembly is used as a power source, and the servo motor 5 can accurately output the corresponding speed and torque according to the control signal. When receiving the control command (which can be the command corresponding to the set height, angle and other parameters input by the operator through the control console, or the command issued according to the preset automatic acquisition program), the output shaft of the motor 5 starts to rotate, driving the worm 7 connected to it to rotate;

[0030] Since the worm 7 is meshed with the two sets of worm wheels 6 provided in the cover 4, according to the gear transmission principle, the rotation of the worm 7 will drive the two sets of worm wheels 6 to rotate synchronously. The screw 8 passes through the cover 4 at the bottom and is connected to the center of the worm wheel 6, so the rotation of the worm wheel 6 will be transmitted to the screw 8, driving the screw 8 to rotate;

[0031] The bottom plate 9 of the acquisition component is provided with two groups of screw holes that match the screw rod 8. The rotation of the screw rod 8 will produce a spiral transmission effect with the screw holes of the bottom plate 9. When the screw rod 8 rotates in a certain direction, driven by the thread, the bottom plate 9 will move up and down along the axial direction of the screw rod 8 (for example, when the screw rod 8 rotates clockwise, the bottom plate 9 moves upward; when the screw rod 8 rotates counterclockwise, the bottom plate 9 moves downward, depending on the design of the rotation direction of the thread), thereby driving the entire acquisition component (including the bottom plate 9, the support plate 10, the top plate 11, the housing 12 and the camera 13 and other components) to achieve overall vertical position adjustment;

[0032] Through the transmission cooperation mode of the worm gear 6, worm 7 and screw 8, on the one hand, the high precision and good self-locking performance of the worm gear 6 and worm 7 can be used to accurately lift the acquisition component to the required height position, so as to realize the morphological data acquisition of surrounding rocks in different height ranges; on the other hand, after reaching the specified height, due to the self-locking property, the acquisition component can be stably maintained at this position, and will not be easily displaced due to factors such as the vibration of the device itself and slight external interference, thereby ensuring that the angle and position of the acquisition component are relatively fixed during the acquisition process, laying a foundation for the subsequent stable and accurate acquisition of surrounding rock morphological data, and solving the problem that it is inconvenient to adjust the acquisition height of the traditional device;

[0033] The acquisition component is mainly composed of a bottom plate 9, a support plate 10, a top plate 11, a housing 12 and a camera 13, which work together to realize the data acquisition function;

[0034] The bottom plate 9 is connected to the screw rod 8 of the lifting assembly through the screw holes provided therein, becoming a key part for connecting the collection assembly with the lifting assembly and realizing position adjustment, ensuring that the collection assembly can accurately move in the vertical direction with the rotation of the screw rod 8, and change the height position to adapt to surrounding rocks of different heights;

[0035] The top plate 11 is arranged on one side above the bottom plate 9, providing a stable mounting platform for the housing 12, so that the housing 12 can be reliably fixed at a suitable position and angle;

[0036] The multiple cameras 13 (evenly arranged with grooves 19 for accommodating the cameras 13, and chamfers 20 are arranged around the grooves 19) arranged on the shell 12 play a core role in data collection. When the device moves and is at a suitable height, the camera 13 starts working and shoots the surface of the surrounding rock from multiple different angles. The design of the groove 19 can not only stably accommodate the camera 13 therein, play a positioning role, and ensure that the shooting angle of the camera 13 is relatively fixed and meets the collection requirements, but also protect the camera 13 from direct collisions, scratches and other damages from external objects to a certain extent; the chamfers 20 around the grooves 19 further optimize this protection function, avoiding bumps and damages to the camera 13 due to sharp edges during installation and use;

[0037] Multiple cameras 13 evenly arranged cover a wide field of view. As the device moves in the tunnel and adjusts its height through the lifting assembly, it can obtain image information of the surrounding rock surface from all directions and angles. These image data contain important features of the surrounding rock, such as texture, color, and cracks, and provide a rich and critical data basis for subsequent analysis of the surrounding rock morphology, surrounding rock classification, and construction of an accurate surrounding rock morphology model, which helps to more accurately grasp the geological conditions along the tunnel.

[0038] When the collection operation is performed, the protection component no longer protects the housing 12 .

[0039] In this embodiment, the protective assembly includes a side panel 14, an auxiliary panel 15, a propeller 16, a protective cover 17 and a connecting block 18. The side panel 14 is fixed on the trolley 1, and the side panel 14 is arranged on the side of the cover body 4. The auxiliary panel 15 is also arranged on the side panel 14. The screw 8 is rotatably connected to the auxiliary panel 15. The propeller 16 is also arranged below the auxiliary panel 15. The protective cover 17 is provided with an opening at one end close to the support plate 10. A connecting block 18 is also arranged below the protective cover 17. The output end of the propeller 16 passes through the side panel 14 and is connected to the connecting block 18. The propeller 16 adopts a cylinder. When there is no need to protect the shell 12, the propeller 16 drives the connecting block 18 to move away from the side panel 14 under the support of the auxiliary panel 15. The protective cover 17 is completely misaligned with the top plate 11. At this time, the top plate 11 drives the shell 12 with the camera 13 to rise.
