Description

Technical Field

[0001] The present invention belongs to the technical field of coal yard laser scanning, and specifically refers to a three-dimensional laser scanning device for coal yards. Background Technique

[0002] Since the coal combustion cost accounts for about 70% of the total cost of coal-fired power plants, and the inventory management of coal yards occupies a large amount of funds and on-site resources of enterprises, and the coal yard inventory management is directly related to aspects such as enterprise fuel safety and procurement fund decision-making, coal plants usually use laser scanners for coal yard inventory.

[0003] Currently, when conducting coal yard inventory, a laser scanner is usually used to emit and receive laser, and it is used as a reference to obtain the three-dimensional coordinates of coal. However, existing laser scanners are usually fixed on the top of the coal yard to scan the coal yard. It is inconvenient to automatically reciprocally adjust the scanning angle of the laser scanning device to scan and inventory the coal in different directions in the coal yard. Moreover, the dust in the coal yard escapes, causing the exposed scanning device to accumulate dust and be difficult to clean. It is inconvenient to conveniently store and take out the scanning device for maintenance. Therefore, there is an urgent need for a three-dimensional laser scanning device for coal yards to solve the above problems. Summary of the Invention

At both ends of the top of the support base, lifting cylinders are fixedly connected relatively.

[0008] In order to smoothly achieve the purpose of facilitating the convenient storage and dust prevention of the scanning device, the storage mechanism includes a dust-proof box fixedly connected to the bottom of the fixed end of the support base, and the top of the dust-proof box is hinged with relatively arranged box covers.

[0009] In order to smoothly achieve the purpose of facilitating the automatic cleaning of the dust accumulated in the storage box, the dust removal mechanism includes a lead screw rotatably connected between the top wall and the bottom wall of the fixed box. A driving motor for driving the rotation of the lead screw is fixedly arranged on the bottom wall of the fixed box.

[0011] Among them, one side wall of the dust-proof box is inclined, and the two groups of fixed boxes are arranged parallel to the inclined side wall. Transparent scanning windows are fixedly arranged on the three side walls of the dust-proof box. Pull rings are fixedly connected to the tops of the two groups of box covers.

[0012] Preferably, both the dust removal brush and the dust collection box are arranged in a U shape.

It further includes a storage mechanism 4, the storage mechanism 4 is provided on the lifting mechanism 3 and can dust-proof and store the scanning device. A fixed box 5 is fixedly connected to the side wall of the storage mechanism 4. It also includes a dust removal mechanism 6, and the dust removal mechanism 6 is provided on the fixed box 5 to facilitate the cleaning of accumulated dust.

[0026] AsFigures 2 - 3 As shown, the adjustable scanning mechanism 2 includes a rotary motor 7 located inside the support box 1 and fixedly connected to a side wall of the support box 1. The output end of the rotary motor 7 is connected to a worm 8. A worm gear 9 is meshed with the worm 8. A support rod 10 is fixedly provided at the bottom of the worm gear 9. The bottom of the support rod 10 is fixedly connected to a transmission plate 11. The support rod 10 can drive the transmission plate 11 to rotate under the rotation of the worm 8. The other end of the transmission plate 11 is rotatably connected to a driven plate 12. A rotating shaft 13 is fixedly connected to the bottom wall of the support box 1. The bottom of the support rod 10 also penetrates and rotatably passes through a limit support plate 14 fixedly connected to one end of the bottom of the support box 1. A three-dimensional scanner 15 is fixedly provided on the top wall of the support box 1. The three-dimensional scanner 15 performs reciprocating rotation under the drive of the driven plate 12 and the rotating shaft 13 to expand the scanning range of the coal yard.

[0027] As Figure 1 、 4 shown, the lifting mechanism 3 includes a support seat 16 rotatably connected to the bottom of the rotating shaft 13, and the other end of the driven plate 12 is rotatably connected to the bottom wall of the support seat 16. Two opposite ends of the top of the support seat 16 are fixedly connected with lifting cylinders 17. The telescopic movement of the lifting cylinders 17 drives the three-dimensional scanner 15 to automatically lift, enabling the three-dimensional scanner 15 to conveniently enter and exit the storage mechanism 4. The storage mechanism 4 includes a dust-proof box 18 fixedly connected to the bottom of the fixed end of the support seat 16. One side wall of the dust-proof box 18 is inclined, and the two fixed boxes 5 are arranged parallel to the inclined side wall. Transparent scanning windows for facilitating the laser scanning of the three-dimensional scanner 15 are fixedly provided on three side walls of the dust-proof box 18. The top of the dust-proof box 18 is hinged with oppositely arranged box covers 19. Pull rings for facilitating the user to grasp and open and close the box covers 19 are fixedly provided on the tops of the two box covers 19.

[0028] As Figure 2 、 4 and 5 shown, the dust removal mechanism 6 includes a lead screw 20 rotatably connected between the top wall and the bottom wall of the fixed box 5. A drive motor 21 for driving the lead screw 20 to rotate is fixedly provided on the bottom wall of the fixed box 5. A guide rod 22 is fixedly provided between the top wall and the bottom wall of the other fixed box 5. A nut block 23 is threadedly connected to the lead screw 20. The other nut block 23 is slidably arranged through the guide rod 22. The guide rod 22 can limit the nut block 23 moving along the lead screw 20 to make it translate linearly. A dust removal brush 24 in a U-shaped setting that fits the three side walls of the dust-proof box 18 is fixedly connected to the nut block 23. The dust removal brush 24 translates along the three side walls of the lifting cylinder 17 in a fitting manner to brush off the accumulated dust. Fixed blocks 25 are fixedly connected to the bottom of the two side walls of the dust-proof box 18 relatively. A dust collection box 26 in a U-shaped setting located below the dust removal brush 24 is inserted and fixed on the top of the fixed block 25, so as to collect the dust brushed off.

[0029] During specific use, when a laser scan of the coal yard is required, turning on the 3D scanner 15 allows the laser to emit through the transparent scan windows on the three side walls of the dust-proof box 18, so that the coal yard scan can be carried out for coal inventory. Turning on the rotary motor 7 drives the worm 8 to rotate, then the worm gear 9 meshes and rotates to drive the support rod 10 to rotate, and then the drive plate 11 rotates accordingly to drive the other end of the driven plate 12 to rotate along the bottom wall of the support base 16. At the same time, the limit support plate 14 provides limit support for the support rod 10 and the bottom of the support box 1, and the rotating shaft 13 at the other end of the support box 1 also rotates along the bottom wall of the support base 16, thereby driving the 3D scanner 15 at the top to rotate back and forth to adjust the angle, thus expanding the scanning range of the 3D scanner 15 for scanning the coal yard. The dust-proof box 18 can prevent the dust escaping from the coal yard from falling on the 3D scanner 15. When there is dust accumulation on the three side walls of the dust-proof box 18, turn on the drive motor 21 to make it rotate forward to drive the lead screw 20 to rotate forward, then the nut block 23 drives the dust removal brush 24 to translate along the guide rod 22 and move along the three side walls of the dust-proof box 18, so that the accumulated dust can be brushed off. Then the dust collection box 26 below can collect the dust that falls after brushing. When the 3D scanner 15 needs to be taken out for maintenance, turn the two sets of box covers 19 to open, and turn on the two sets of lifting cylinders 17 to make them extend to drive the support base 16 to rise, so that the 3D scanner 15 can be moved out of the dust-proof box 18, thus facilitating the user to conveniently take and maintain the 3D scanner 15. The above is the entire usage process of the 3D laser scanning equipment for the coal yard.
