Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8 , the present invention provides a technical solution: an installation rack for an unmanned autonomous navigation sensor array of a mine car, including a mounting plate 1 and a mine car body 2. A plurality of limiting plates 3 arranged linearly at equal intervals and arranged front and back are slidably connected to the left side surface of the mounting plate 1. A sensor body 4 is installed on the left side surface of the limiting plate 3, and the mounting plate 1 is fixed on the left side surface of the mine car body 2. It further includes:

[0031] A limiting mechanism 6 is arranged on the left side surface of the mounting plate 1 and is used to limit a plurality of limiting plates 3. The limiting mechanism 6 includes two fixing plates 61 fixed on the left side surface of the mounting plate 1 near the front end and arranged up and down, two rotating columns 62 rotatably connected to the same side fixing plate 61, a screw 63 coaxially fixed between the two rotating columns 62, a moving plate 64 threadedly connected to the screw 63 and slidably connected to the left side surface of the mounting plate 1, a moving rod 65 fixed on the rear side surface of the moving plate 64, a limiting rod 66 fixed on the bottom surface of the moving rod 65 and slidably inserted into a plurality of limiting plates 3, a rotating rod 68 coaxially fixed on the surface of one of the rotating columns 62 away from the screw 63, two gears 69 located on the left side of the mounting plate 1 and used to drive the rotating rod 68 to rotate, and a motor 610 installed on the surface of one of the fixing plates 61 away from the screw 63 and used to drive the two gears 69 to rotate. The two gears 69 mesh with each other. By arranging a plurality of limiting plates 3 arranged linearly at equal intervals, a plurality of sensor bodies 4 can be installed. The plurality of limiting plates 3 are slidably connected to the left side surface of the mounting plate 1. By arranging the limiting mechanism 6, a plurality of limiting plates 3 can be limited, and a plurality of sensor bodies 4 can be limited, so as to facilitate the disassembly and assembly of the plurality of limiting plates 3, and further facilitate the disassembly, inspection or replacement of the plurality of sensor bodies 4.

[0032] In this embodiment, the limiting mechanism 6 further includes a rotating shaft 611 coaxially connected to the output shaft of the motor 610, and two gears 69 are respectively and coaxially fixed on the circumferential outer walls of the rotating shaft 611 and the rotating rod 68, which can smoothly drive the two gears 69 to rotate, and further can smoothly drive the screw 63 to rotate.

[0033] In addition, a vertically arranged guiding groove is provided at the front end near the left surface of the mounting plate 1, and a guiding block 67 fixedly connected to the guiding groove on the left surface of the mounting plate 1 is provided on the right surface of the moving plate 64, which can guide the movement of the moving plate 64, and further can indirectly guide the movement of a plurality of limiting rods 66.

[0034] Furthermore, a plurality of limiting holes are provided on the top surface of the limiting plate 3, and the limiting rods 66 are slidably inserted into the same-side limiting holes on the outer wall of the same-side limiting plate 3, which can smoothly limit a plurality of limiting plates 3.

[0035] Specifically, two horizontally arranged sliding grooves are provided on the left surface of the mounting plate 1, and two sliding strips 5 fixedly connected to the same-side sliding grooves on the left surface of the mounting plate 1 are provided on the right surface of the limiting plate 3, which can guide the disassembly and assembly of a plurality of limiting plates 3.

[0036] It should be noted that the transverse sectional shape of the guiding groove on the left surface of the mounting plate 1 is convex-shaped, and the shape of the guiding block 67 is convex-shaped and adapted to the shape of the guiding groove on the left surface of the mounting plate 1. This can make the connection between the guiding block 67 and the guiding groove on the left surface of the mounting plate 1 closer, and further indirectly make a plurality of limiting rods 66 more stable during movement.

[0037] It should be noted that the limiting mechanism 6 further includes a protection box 612 fixed on the surface of one of the fixing plates 61 away from the screw 63. The motor 610 is located inside the protection box 612, and the rotating shaft 611 penetrates through the outer wall of the protection box 612 away from the screw 63.

This can make the connection between the sliding strip 5 and the same-side sliding groove on the left surface of the mounting plate 1 closer, prevent the sliding strip 5 from detaching from the same-side sliding groove on the left surface of the mounting plate 1, and further indirectly make the connection between the limiting plate 3 and the mounting plate 1 closer.

[0039] Finally, it should be noted that components such as the mine car body 2, the sensor body 4, and the motor 610 involved in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. At the idle places of this device, all the above-mentioned electrical components, which refer to power components, electrical components, and the adapted controllers and power supplies, are connected by wires.

[0040] In the specific use process of this embodiment, when it is necessary to disassemble, repair, or replace several sensor bodies 4, first, start the motor 610 through an external PLC. The output shaft of the motor 610 rotates to drive the coaxial connection shaft 611 to rotate. The rotation of the shaft 611 drives the same-side gear 69 fixedly connected to it coaxially to rotate. The rotation of this gear 69 drives another gear 69 meshing with it to rotate. The rotation of the other gear 69 drives the rotating rod 68 fixedly connected to it coaxially to rotate. The rotation of the rotating rod 68 drives the same-side rotating column 62 fixedly connected to it coaxially to rotate. The rotation of this rotating column 62 drives the screw 63 fixedly connected to it coaxially to rotate. The rotation of the screw 63 drives the moving plate 64 threadedly connected to it to move upward. The moving plate 64 moves under the guiding action of the guiding block 67 and the guiding groove on the left surface of the mounting plate 1. The movement of the moving plate 64 drives the moving rod 65 fixed to it to move. The movement of the moving rod 65 drives several limiting rods 66 fixed to it to move upward. When several limiting rods 66 are all separated from the same-side limiting holes on the outer wall of the same-side limiting plate 3, turn off the motor 610 through an external PLC. Immediately afterwards, move several limiting plates 3 until several sliding strips 5 are all separated from the same-side sliding grooves on the outer wall of the mounting plate 1, then the disassembly work of several limiting plates 3 and several sensor bodies 4 is completed. Thus, several sensor bodies 4 can be repaired. When one or more sensor bodies 4 need to be replaced, the sensor body 4, the connected limiting plate 3, and the two sliding strips 5 can be replaced as a whole. According to the above description, conversely, several sensor bodies 4 that have been repaired or replaced can be installed.
