For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0036] See Figures 1 to 6 , this application provides an anti-slip sand laying device, including:

[0037] Two tracks 2, and the two tracks 2 are used to be connected to the deck main body 1;

[0038] It should be noted that the track 2 is installed at the top of the deck main body 1, and the spreading range of the anti-slip sand can be changed by adjusting the position of the track 2;

[0039] It should also be noted that the connection mode between the track 2 and the deck main body 1 is a detachable connection, such as bolts;

[0040] The sand spreading vehicle 3 is arranged on the two tracks 2; a plurality of roller groups are arranged at the bottom of the sand spreading vehicle 3, each roller group includes two rollers 4, the two rollers 4 are fixedly connected by a connecting shaft 5, and the connecting shaft is perpendicular to the track; the connecting shaft 5 of one of the roller groups is controlled to rotate by a power assembly;

[0041] The material spreading bin 15 includes two material spreading bins 15. Each material spreading bin 15 is a rectangular frame structure with an opening at the lower part. The material spreading bin 15 is used for storing anti-slip sand, and the anti-slip sand in the material spreading bin 15 can be spilled out through the opening at the lower part. The material spreading bin 15 is a strip-shaped structure, the arrangement direction of the material spreading bin 15 is perpendicular to the direction of the track 2, and they are respectively arranged on both sides of the sand spreading vehicle 3;

[0042] The power assembly includes:

[0043] The first bevel gear 6 is coaxially and fixedly connected to the outer wall of the connecting shaft 5;

[0044] The first rotating shaft 8, a second bevel gear 7 is arranged at the bottom of the first rotating shaft 8, and the first rotating shaft 8 is perpendicular to the connecting shaft 5; a pulley 9 is arranged at the top of the first rotating shaft 8;

[0045] The second rotating shaft 10 is arranged parallel to the first rotating shaft 8 and is in transmission connection with the pulley 9. A motor 11 is arranged at the bottom of the second transmission shaft 10. After the motor 11 controls the second rotating shaft 10 to rotate, it drives the pulley 9 to rotate, thereby controlling the second rotating shaft 8 and the connecting shaft 5 to rotate.

[0046] It should be noted that the power assembly is arranged in the middle of the connecting shaft 5.

[0047] Through the setting of the power component, when it is necessary to sprinkle anti-slip sand on the top of the deck main body 1, then control the motor 11 to start. The start of the motor 11 drives the rotation of the second rotating shaft 10. The rotation of the second rotating shaft 10 drives the rotation of the first rotating shaft 8 through the transmission of the pulley 9. The rotation of the first rotating shaft 8 drives the rotation of the second bevel gear 7. The rotation of the second bevel gear 7 drives the rotation of the first bevel gear 6. The rotation of the first bevel gear 6 drives the rotation of the connecting shaft 5. The rotation of the connecting shaft 5 drives the rotation of the roller 4, so that the roller 4 moves on the top of the track 2, thereby moving the sand spreading vehicle 3. The anti-slip sand inside the sand spreading vehicle 3 is sprinkled out to the top of the deck main body 1 through the material spreading bin 15. Compared with the manual sand spreading method, it can not only ensure the uniformity of the distribution of the anti-slip sand, but also avoid the existence of anti-slip dead corners and potential safety hazards, and avoid the problem that the staff is fatigued and the work efficiency is low, and improve the work efficiency of spreading the anti-slip sand.

[0048] In an implementable manner, as Figure 4 shown, the material spreading bin 15 includes a bottom plate provided at the bottom, and a material spreading opening is arranged on the bottom plate. A baffle is arranged below the bottom plate, and the position of the baffle is adjustable. After the position of the baffle is adjusted, the opening and closing of the material spreading opening are controlled.

[0049] Both ends in the length direction of the baffle 16 are slidably connected to the material spreading bin 15, and the width of the baffle 16 is smaller than the width of the material spreading bin 15; a magnetic block 23 is arranged on one side of the baffle 16 in the width direction, and an electromagnet 22 is arranged on the material spreading bin 15, and the position of the electromagnet 22 corresponds to the position of the magnetic block 23. After the electromagnet 22 is powered on, it is connected to the magnetic block 23, and the side of the baffle 16 is connected to the material spreading bin 15, so that a strip-shaped material spreading opening is formed between the other side of the baffle 16 and the bottom plate.

[0050] Specifically, control the electromagnet 22 to start. The electromagnet 22 generates a suction force on the magnetic block 23, so that the magnetic block 23 moves to the side of the electromagnet 22, thereby moving the baffle 16, controlling the opening of the material spreading opening, and spreading the anti-slip sand. After controlling the electromagnet 22 to close, after the baffle 16 moves, control the material spreading opening to close. Through the setting of the electromagnet and the magnetic block, the opening and closing of the material spreading opening can be automatically controlled.

[0051] It should be noted that the electromagnet 22 can be controlled to open and close through a system such as a PLC.

[0052] In an implementable manner, as Figure 4As shown, a spring is provided on the side of the baffle 16 where the magnetic block is arranged, and the spring is respectively connected to the baffle 16 and the sand spreading bin 15. When spreading anti-slip sand, the baffle 16 moves to squeeze the spring 24 to deform and store elastic potential energy. When sand spreading is not required, by cutting off the power supply of the electromagnet 22, the electromagnet 22 no longer generates suction force on the magnetic block 23, and the spring 24 releases the elastic potential energy to push the baffle 16 to move, so that the sand spreading port is closed.

[0053] In an implementable manner, as Figure 5 and Figure 6 shown, a spiral auger 14 is arranged in each of the two sand spreading bins 15. A fourth bevel gear 13 is arranged at the end of the two spiral augers 14, and the fourth bevel gear 13 is meshed and installed at the top of the third bevel gear 12. By setting the first motor, the walking of the present application and the rotation of the spiral auger 14 can be controlled simultaneously.

[0054] In an implementable manner, a chamber for storing anti-slip sand is arranged at the top of the sand spreading bin 15. Two openings are arranged at the bottom end of the chamber, and each opening is respectively arranged above each spiral auger 14. The anti-slip sand inside the sand spreading vehicle 3 can fall into the inside of the spiral auger 14 through the openings;

[0055] When spreading anti-slip sand, the rotation of the third bevel gear 12 drives the rotation of the fourth bevel gear 13, the rotation of the fourth bevel gear 13 drives the rotation of the spiral auger 14, and the spiral auger 14 rotates to transport the anti-slip sand to the inside of the sand spreading bin 15, so that there is always a certain amount of anti-slip sand inside the sand spreading bin 15, ensuring the uniformity of spreading and improving the stability during sand spreading.

[0056] In an implementable manner, as Figures 1 to 6 shown, sliders 17 are arranged at the ends of the baffle 16 in the length direction, and the sliders 17 are fixedly connected to the baffle 16; a chute is arranged at the bottom of the sand spreading bin 15, and the sliders 17 are slidably connected in the chute.

[0057] A threaded rod 19 is arranged at the bottom of the sand spreading bin 15. A limit block 18 is arranged at the end of the threaded rod 19, and the limit block 18 is threadedly connected to the threaded rod 19. By rotating the threaded rod 19, the position of the limit block 18 on the threaded rod 19 can be adjusted. The limit block 18 is arranged at the end of the chute and is used to limit the sliding length of the baffle 16 to prevent the slider 17 from sliding out of the chute, thereby controlling the width of the sand spreading port formed between the baffle 16 and the bottom plate.

[0058] In an implementable manner, a handwheel 21 is arranged after the threaded rod 19 extends outwards. The handwheel 21 is used to control the rotation of the threaded rod 19, so as to adjust the position of the limit block 18 on the threaded rod 19. When it is necessary to adjust the amount of sand fed, the handwheel 21 can be rotated. The rotation of the handwheel 21 drives the rotation of the threaded rod 19, and the rotation of the threaded rod 19 drives the movement of the limit block 18. The limit block 18 moves on one side of the slider 17. When the electromagnet 22 is activated to drive the baffle 16 to move and open, the movement position of the slider 17 is limited by the limit block 18, so as to adjust the amount of sand fed and improve the adaptability of the equipment.

[0059] In an implementable manner, the baffle 16 can be provided with two, and the two baffles are arranged in parallel. And magnetic blocks are respectively arranged on each baffle. After the two baffles move simultaneously, the opening and closing of the material discharging port are controlled.

[0060] Specifically, as Figures 1 to 6 shown, two sections of threads are arranged on the outer wall of the threaded rod 19, and the thread directions of the two sections of threads are opposite. A limit block is arranged on each of the two sections of threads. After the threaded rod is rotated, the two limit blocks move towards each other or in opposite directions simultaneously.

[0061] In an implementable manner, as Figure 3 and Figure 4 shown, an observation block 20 is fixedly installed at the top end of the limit block 18, and the observation block 20 extends upwards to the outside of the material discharging bin 15.

[0062] Specifically, an opening is arranged at the top end of the material discharging bin 15, and scale lines are arranged at the opening. The opening degree of the material discharging port is determined based on the scale lines. When adjusting the amount of sand fed, the movement of the limit block 18 drives the movement of the observation block 20. The position of the observation block 20 at the scale lines is convenient for the staff to observe the specific value of the adjustment and ensure the accuracy of the adjustment.

[0063] In an implementable manner, as Figure 5 and Figure 6 shown, a chamber for storing anti-slip sand is arranged at the top of the material discharging bin 15. Two openings are arranged at the bottom end of the chamber, and each opening is respectively arranged above each spiral auger 14; the top end of the fourth bevel gear 13 is meshed with a fifth bevel gear 25, a sixth rotating shaft 26 is fixedly installed inside the fifth bevel gear 25, a rotating plate 27 is fixedly installed on the outer wall of the sixth rotating shaft 26, the rotating plate 27 is rotatably installed inside the chamber, and the rotating plate is arranged vertically and sweeps the anti-slip sand in the chamber after rotation.

[0064] When sand is being sprinkled, the rotation of the fourth bevel gear 13 can drive the rotation of the fifth bevel gear 25. The rotation of the fifth bevel gear 25 drives the rotation of the sixth rotating shaft 26, and the rotation of the sixth rotating shaft 26 drives the rotation of the rotating plate 27, causing the rotating plate 27 to stir the anti-slip sand stored inside the sand-sprinkling vehicle 3, facilitating the anti-slip sand to fall into the interior of the spiral auger 14.

[0065] In an implementable manner, as Figure 5 shown, two elastic pieces 28 are fixedly installed inside the material-spreading bin 15. The two elastic pieces 28 are respectively arranged on both sides of the rotating plate 27, and after the rotating plate 27 rotates, it abuts against the elastic pieces.

[0066] When the rotating plate 27 rotates and contacts one of the elastic pieces 28, the elastic piece 28 deforms under force and releases the elastic potential energy to reset after separating from the rotating plate 27, shaking the anti-slip sand at the four corners inside the sand-sprinkling vehicle 3, facilitating the anti-slip sand at the four corners to enter the interior of the material-spreading bin 15.

[0067] When this application is in use, it at least includes the following content:

[0068] When it is necessary to sprinkle anti-slip sand on the top of the deck main body 1, first load anti-slip sand into the interior of the sand-sprinkling vehicle 3, and then adjust the sand-sprinkling amount as needed. When adjusting, rotate the handwheel 21. The rotation of the handwheel 21 drives the rotation of the threaded rod 19. The rotation of the threaded rod 19 drives the movement of the limit block 18, causing the limit block 18 to move on one side of the slider 17. The movement position of the slider 17 is limited by the limit block 18. At the same time, the movement of the limit block 18 drives the movement of the observation block 20, and the staff can adjust by obtaining the position of the observation block 20.

[0069] The PLC is used to control the electromagnet 22 to generate suction force on the magnetic block 23, causing the baffle 16 to slide. After the two baffles 16 slide in opposite directions, the material-spreading opening is opened, and the anti-slip sand inside the material-spreading bin 15 drops and is scattered.

[0070] At the same time, the motor 11 is controlled to start. The start of the motor 11 drives the rotation of the second rotating shaft 10. The rotation of the second rotating shaft 10 drives the rotation of the first rotating shaft 8 through the belt pulley 9. The rotation of the first rotating shaft 8 drives the rotation of the second bevel gear 7. The rotation of the second bevel gear 7 drives the rotation of the first bevel gear 6. The rotation of the first bevel gear 6 drives the rotation of the connecting shaft 5. The rotation of the connecting shaft 5 drives the rotation of the roller 4, causing the roller 4 to move on the top of the track 2, so that the sand-sprinkling vehicle 3 moves to evenly sprinkle sand on the top of the deck main body 1.

[0071] When the second rotating shaft 10 rotates, it drives the third bevel gear 12 to rotate. The rotation of the third bevel gear 12 drives the rotation of the fourth bevel gear 13. The rotation of the fourth bevel gear 13 drives the rotation of the spiral auger 14, and the rotation of the spiral auger 14 transports the anti-skid sand inside the sand spreading vehicle 3.

[0072] When the fourth bevel gear 13 rotates, it drives the rotation of the fifth bevel gear 25. The rotation of the fifth bevel gear 25 drives the rotation of the sixth rotating shaft 26. The rotation of the sixth rotating shaft 26 drives the rotation of the rotating plate 27, so that the rotating plate 27 stirs the anti-skid sand inside the sand spreading vehicle 3, facilitating the transmission of the anti-skid sand to the inside of the material spreading bin 15.

[0073] After sand spreading, the motor 11 is turned off, and the electromagnet 22 is powered off. The elastic potential energy is released through the spring 24 to push the baffle 16 to move. After the two baffles 16 move towards each other and fit together, the material spreading opening is closed, and the anti-skid sand no longer spills out.

[0074] In summary, the present application can lay anti-skid sand on the ship deck. Through the setting of the power assembly, when it is necessary to spread anti-skid sand on the top of the deck body, the roller can be controlled to move on the top of the track, so that the sand spreading vehicle moves, ensuring the uniformity of the distribution of the anti-skid sand and avoiding anti-skid dead corners and potential safety hazards. The work efficiency is improved. Through the setting of the electromagnet and the magnetic block, the opening and closing of the material spreading opening can be automatically controlled. By setting the threaded rod, the opening size of the material spreading opening can be adjusted, so as to adjust the amount of sand falling, improving the adaptability of the equipment.

[0075] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
