[0049] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1:

[0051] Embodiment 1 of this utility model provides a laser radar coal counting device, such as... Figure 1 and Figure 2 As shown, it includes: a slide rail 1, a sliding assembly 2, a rotating assembly 3, and a lidar 4; the sliding assembly 2 is slidably connected to the slide rail 1, the rotating assembly 3 is rotatably connected to the sliding assembly 2, the lidar 4 is fixedly disposed below the rotating assembly 3, and the slide rail 1 is fixedly disposed on the top of the warehouse; wherein, in order to enable the sliding assembly 2 to move on the slide rail 1, as follows... Figure 2 and Figure 3 As shown, the sliding assembly 2 includes a gear set 20 and a hollow rod 21, the slide rail 1 includes a rack 10 and a slide rod 11, the gear set 20 meshes with the rack 10, and the hollow rod 21 is sleeved on the outside of the slide rod 11 and slidably connected to the slide rod 11.

[0052] The sliding rail 1 and sliding component 2 allow the lidar 4 to be moved to different positions on the sliding rail 1. The gear set 20 meshes with the rack 10 to enable bidirectional movement of the sliding component 2 on the sliding rail 1. The hollow rod 21 and the sliding rod 11 are sleeved together to further fix the sliding component 2. At the same time, the lidar 4 is fixed to the rotating component 3, allowing the lidar 4 to rotate 360 ​​degrees, further increasing the scanning range of the lidar 4. This enables the volume scanning and calculation of coal stacks at any location in the warehouse, effectively overcoming the problems of high cost of static lidar coal inventory mode and low timeliness of dynamic acquisition using handheld lidar moving around coal stacks in the existing technology.

[0053] To illustrate the technical solution provided by this utility model, the structural details of the above solution will be described in further detail below.

[0054] In order for the sliding component 2 to be installed on the slide rail 1, such as Figure 4 As shown, the slide rail 1 further includes a first fixing plate 13, a second fixing plate 14, and a first connecting plate 15. The first connecting plate 15 is respectively disposed on both sides of the second fixing plate 14, and both ends of the first connecting plate 15 are fixedly connected to the first fixing plate 13 and the second fixing plate 14, respectively. The rack 10 is fixedly installed on the upper surface of the second fixing plate 14. First mounting plates 130 extend from the lower surfaces of both sides of the first fixing plate 13, and the slide rod 11 is fixedly disposed on the lower surface of the first mounting plate 130. The first fixing plate 13 is fixedly connected to the top of the warehouse.

[0055] For gear set 20, in order to achieve bidirectional movement of sliding component 2, such as Figure 5 As shown, the gear set 20 includes a first driving gear 200, a first driven gear 201, and a second driven gear 202. The first driving gear 200 is located between the first driven gear 201 and the second driven gear 202, and the first driving gear 200 meshes with both the first driven gear 201 and the second driven gear 202. The first driving gear 200, the first driven gear 201, and the second driven gear 202 are rotatably connected to the sliding assembly 2. The first driving gear 200, the first driven gear 201, and the second driven gear 202 mesh with the rack 10. The sliding assembly 2 also includes a first motor 22, which drives the first driving gear 200 to rotate. The motor shaft of the first motor 22 is fixedly connected to the gear center of the first driving gear 200 to drive the first driving gear 200 to rotate. When the motor shaft of the first motor 22 rotates clockwise, the sliding component 2 moves toward the first driven gear 201; when the motor shaft of the first motor 22 rotates counterclockwise, the sliding component 2 moves toward the second driven gear 202.

[0056] To enable the sliding assembly 2 to be mounted on the slide rail 1, the sliding assembly 2 further includes a third fixing plate 23, a fourth fixing plate 24, and a second connecting plate 25. The second connecting plate 25 is disposed on both sides of the third fixing plate 23, and its two ends are fixedly connected to the third fixing plate 23 and the fourth fixing plate 24, respectively. The first driving gear 200, the first driven gear 201, and the second driven gear 202 are rotatably connected to the third fixing plate 23. The first motor 22 is fixed to the side of the third fixing plate 23. The upper surface of the fourth fixing plate 24 is provided with two second mounting plates 240, which are respectively disposed on both sides of the third fixing plate 23. The hollow rod 21 is disposed on the top of the second mounting plate 240 and is sleeved on the outside of the slide rod 11, slidably connected to the slide rod 11.

[0057] Since the two ends of the second connecting plate 25 are fixedly connected to the third fixing plate 23 and the fourth fixing plate 24 respectively, during installation, the second connecting plate 25 needs to pass through the first connecting plate 15 so that the gear set 20 meshes with the rack 10. Therefore, as Figure 6 As shown, the first connecting plate 15 is provided with a through groove 150, which is used for the second connecting plate 25 to pass through. One end of the through groove 150 is provided with a notch (i.e., Figure 6(At the position corresponding to the welding block 151). In the actual installation process, after the sliding component 2, rotating component 3 and lidar 4 are installed, they need to be installed as a whole onto the slide rail 1 so that the gear set 20 meshes with the rack 10. Therefore, a welding block 151 is machined and provided at one end of the first connecting plate 15. When the sliding component 2 is installed on the slide rail 1, the welding block 151 is welded to the main body of the first connecting plate 15 to close one end of the first connecting plate 15.

[0058] For rotating component 3, such as Figure 7 , Figure 8 and Figure 9 As shown, the rotating assembly 3 includes a third driven gear 30 and a first mounting base 31. The third driven gear 30 is fixed to the top of the first mounting base 31. The top of the fourth fixing plate 24 is provided with a first receiving groove 241 and a second motor 242. The third driven gear 30 is placed in the first receiving groove 241, and the second motor 242 is located on one side of the first receiving groove 241. Figure 10 As shown, a second driving gear 243 is fixedly mounted on the bottom of the second motor 242, and the second driving gear 243 meshes with the third driven gear 30. When the motor shaft of the second motor 242 rotates clockwise, the third driven gear 30 rotates counterclockwise, thereby driving the first mounting base 31 to rotate counterclockwise. When the motor shaft of the second motor 242 rotates counterclockwise, the third driven gear 30 rotates clockwise and counterclockwise, thereby driving the first mounting base 31 to rotate clockwise.

[0059] In order to fix the lidar 4, see [link / reference] Figure 7 and Figure 7a As shown, the first mounting base 31 has downwardly extending fixing protrusions 310 on both sides, and the lidar 4 has fixing grooves 40 on both sides. The fixing protrusions 310 and the fixing grooves 40 are fixedly connected. The fixing protrusions 310 and the fixing grooves 40 can be fixedly connected by bolts.

[0060] According to the above scheme, in practical application scenarios, the number of the lidar coal inventory devices is at least two. When the number of lidar coal inventory devices is two, such as... Figure 11 As shown in the dashed box, the projection of the lidar coal counting device on the horizontal plane is parallel.

[0061] During the actual monitoring process of lidar 4, the control system of lidar 4 adjusts the position of lidar 4 on slide rail 1 according to the position of the coal pile in the warehouse. Here, it is assumed that there are two lidar coal-palletizing devices. Figure 12As shown, they are respectively named the first device 1' and the second device 2'. The first device 1' is located at the top in the following figure, and the second device 2' is located at the bottom in the following figure. The leftmost end of the first device 1' is the tail of the slide rail 1, and the rightmost end is the top of the slide rail 1. The leftmost end of the second device 2' is the top of the slide rail 1, and the rightmost end is the tail of the slide rail 1. In the following description, left, right, top, and bottom refer to the orientation shown in the figure. In the figure, black dots represent the lidar 4. Figure 13 As shown, when the coal pile is located in the left-side area of ​​the warehouse, the lidar 4 of the first device 1' is located at the tail of the slide rail 1, and the lidar 4 of the second device 2' is located at the top of the slide rail 1; as Figure 14 As shown, when the coal pile is located in the right-side area of ​​the warehouse, the lidar 4 of the first device 1' is located at the top of the slide rail 1, and the lidar 4 of the second device 2' is located at the tail of the slide rail 1; as Figure 15 As shown, when the coal pile is located in the lower area of ​​the warehouse, the lidar 4 of the first device 1' is located in the middle of the slide rail 1, and the lidar 4 of the second device 2' is located at the tail of the slide rail 1; as Figure 16 As shown, when the coal pile covers the entire area of ​​the warehouse, the lidar 4 of the first device 1' is located in the middle of the slide rail 1, and the lidar 4 of the second device 2' is also located in the middle of the slide rail 1; Figure 17 As shown, when the coal stack is located in the middle area of ​​the warehouse, the lidar 4 of the first device 1' is located on top of the slide rail 1, and the lidar 4 of the second device 2' is located on top of the slide rail 1.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
