[0017] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] Example like Figure 1-10As shown, a safety guardrail for lithium carbonate production equipment is provided, including a mounting plate 1, a plate groove 2 is integrally formed inside the mounting plate 1, a threaded rod 3 is rotatably connected to the inner lower surface of the plate groove 2 through a rotating shaft, a guide rod 4 is fixedly installed on the inner lower surface of the mounting plate 1 and located on the right side of the threaded rod 3, a gear 5 is fixedly installed on the outer side wall of the threaded rod 3, a gear 2 6 is meshed and installed on the outer side wall of the gear 5, a rotating column 7 is fixedly connected to the rear surface of the gear 2 6, the rear end of the rotating column 7 passes through the rear of the mounting plate 1 and is fixedly installed with a handle 8, a protective plate 9 is provided above the mounting plate 1, and hole grooves 10 are integrally formed on both sides of the inner side of the protective plate 9, the top of the threaded rod 3 and the top of the guide rod 4 extend to the inner sides of the two hole grooves 10 respectively, and the threaded rod 3 and The hole groove 10 is threadedly connected, and the guide rod 4 is slidably connected to the hole groove 10. A through-type extrusion groove 11 is opened on the front surface of the protective plate 9. The top of the extrusion groove 11 penetrates to the top of the protective plate 9. A plurality of springs 12 are fixedly installed on the lower surface of the inner part of the extrusion groove 11. A blocking plate 13 is provided above the inner part of the extrusion groove 11. A safety plate 14 is provided inside the extrusion groove 11 and between the spring 12 and the blocking plate 13. A rotating column 15 is fixedly installed on the right side of the blocking plate 13. The right end of the rotating column 15 penetrates to the right side of the protective plate 9 and is fixedly installed with a regulating valve 16. A plurality of buffer columns 18 are fixedly installed on the front surface of the mounting plate 1. The outer side walls of the plurality of buffer columns 18 are all sleeved with buffer springs 19. The front ends of the plurality of buffer springs 19 are jointly fixed with a buffer plate 20. The threaded rod 13 is threadedly connected to the hole groove 10 of the protective plate 9, and the guide rod 4 slides with the hole groove 10 to form a lifting structure of "thread drive + guide limit". When the handle 8 is turned, the rotating column 7 drives the gear 2 6 to rotate, and the threaded rod 13 is driven to rotate through the meshing transmission of gear 15 and gear 2 6, so that the protective plate 9 can be stably lifted and lowered along the guide rod 4 to ensure no deviation and improve the stability of the structure; the safety plate 14 is located in the extrusion groove 11, supported by the spring 12 at the bottom and limited by the blocking plate 13 at the top. When the regulating valve 16 is rotated, the rotating column 15 drives the blocking plate 13 to rotate to release the blockage of the safety plate 14, so that it pops up upward under the elastic force of the spring 12 to extend, and the reverse rotation can extend the safety plate 14. The plate 14 is pressed back and fixed, which is easy to operate and the protection range can be flexibly adjusted; the buffer column 18 and the buffer spring 19 on the front surface of the mounting plate 1 form a double buffer mechanism. When the buffer plate 20 is hit, the buffer spring 19 absorbs the impact force by deformation, and the buffer column 18 limits its deformation direction to avoid excessive deviation. At the same time, the buffer plate 20 disperses the impact force to multiple buffer springs 19, further improving the buffering effect and reducing collision damage; in addition, the hole groove 10 of the protective plate 9 needs to match the thread specifications of the threaded rod 3 and the outer diameter of the guide rod 4 to ensure the smoothness of the threaded connection and the stability of the sliding fit. The size of the extrusion groove 11 should also be adapted to the safety plate 14, the blocking plate 13 and the spring 12 to ensure reliable linkage of each component.
[0019] like Figure 1 Figure 7 As shown, a warning plate 21 is fixedly installed on the front surface of the buffer plate 20, and a horizontal groove 22 is integrally formed on the front surface of the warning plate 21. A slide groove 23 is opened on the front surface of the warning plate 21 and above the horizontal groove 22. A plurality of warning posts 24 are rotatably connected to the lower surface of the inner portion of the horizontal groove 22 by a rotating shaft. The top ends of the plurality of warning posts 24 all pass through the interior of the slide groove 23 and are fixedly installed with a rotating block 25. A second threaded rod 26 is rotatably installed inside the slide groove 23 and above the rotating block 25 by a rotating shaft. The right end of the second threaded rod 26 passes through the right side of the warning plate 21 and is fixedly installed with a motor 27. The left end of the output end of the motor 27 is fixedly connected to the right end of the second threaded rod 26. An L-shaped support plate 32 is fixedly installed on the right side of the motor 27. The left end of the L-shaped support plate 32 is fixedly installed to the right side of the warning plate 21. like Figure 1 Figure 7 Figure 10 As shown, the outer wall of the threaded rod 26 is threadedly mounted with a threaded block 28, the lower surface of the threaded block 28 is integrally formed with a functional groove 29, the interior of the functional groove 29 is provided with a paddle 30, the front surface of the rotating block 25 is fixedly mounted with a baffle 31, the paddle 30 and the baffle 31 are adapted; like Figure 1 Figure 8 As shown, the lower surface of the threaded block 28 and located in front of the warning plate 21 is fixedly mounted with a wiper plate 33, the transverse groove 22 and the plurality of warning posts 24 on opposite sides and located on the outer side wall of the shaft are fixedly mounted with a torsion spring 34; The warning plate 21 forms a linkage space through the transverse groove 22 and the slide 23 on its front surface. Multiple warning posts 24 within the transverse groove 22 rotate around the shaft, their top ends extending through the slide 23 and securing the rotating block 25. A torsion spring 1 (34) is fixed to both the transverse groove 22 and the warning posts 24 on the outer side of the shaft. This provides a restoring force after the warning posts 24 rotate, ensuring they maintain their initial position when no external force is applied. A threaded rod 26 within the slide 23 is driven by a motor 27, which is securely mounted to the right side of the warning plate 21 via an L-shaped support plate 32, ensuring stable power output. A threaded block 28 on the threaded rod 26 translates left and right as it rotates. A paddle 30 within a functional groove 29 on its lower surface mates with a stopper 31 in front of the rotating block 25. When the threaded block 28 moves, the paddle 30 pushes the stopper 31, causing the warning posts 24 to rotate about the shaft. This, in conjunction with the torsion spring 1 (34), automatically resets the warning posts 24. At the same time, the wiping plate 33 on the lower surface of the threaded block 28 is located in front of the warning plate 21. When it moves synchronously with the threaded block 28, it can wipe the surface of the warning column 24. As the brush head 41 moves toward the warning column 24 to wipe the reflective strip 40, the movement of the brush head 41 and the relative rotation of the warning column 24 cooperate to achieve a better wiping effect and realize the cleaning function, preventing the adhesion of dust and other stains in the lithium carbonate production environment from affecting the warning effect, and ensuring the clarity of the warning on the warning column 24. In addition, the size of the slide 23 needs to be compatible with the movement trajectory of the threaded block 28. The contact angle and force of the paddle 30 and the baffle 31 should be designed to effectively drive the rotating block 25 while avoiding excessive compression and structural damage, ensuring the reliability of the overall linkage.
[0020] like Figure 5 Figure 9 As shown, a positioning hole 35 is opened on the right side of the protective plate 9 and on the left side of the regulating valve 16. A positioning rod 36 is provided on the inner wall of the positioning hole 35. The right side of the positioning rod 36 passes through the right side of the regulating valve 16 and is fixedly connected to a hand-held block 37. like Figure 5 Figure 9 As shown, a spring 2 17 is fixedly connected between the hand-held block 37 and the regulating valve 16 and located on the outside of the positioning rod 36; The positioning hole 35 on the right side of the protective plate 9 cooperates with the positioning rod 36 to form a fixed stop for the blocking plate 13. The positioning rod 36 passes through the regulating valve 16 and extends into the positioning hole 35. Its right end is conveniently operated by a handle block 37. A spring 2 17 between the handle block 37 and the regulating valve 16 is sleeved on the outside of the positioning rod 36, providing a continuous blocking elastic force to ensure that the positioning rod 36 is stably engaged in the positioning hole 35, thereby fixing the position of the regulating valve 16 and the blocking plate 13 and preventing the safety plate 14 from accidentally popping out or falling back due to external force. When the blocking plate 13 needs to be adjusted, pulling the handle block 37 to the right drives the positioning rod 36 out of the positioning hole 35, releasing the stop. At this time, the regulating valve 16 can be rotated to adjust the position of the blocking plate 13. After releasing the handle block 37, the elastic force of the spring 2 17 drives the positioning rod 36 to automatically reset and re-engage the corresponding positioning hole 35, achieving rapid positioning and fixation, improving operational convenience and structural stability.
[0021] like Figure 1 Figure 2 Figure 3 As shown, support legs 38 are fixedly mounted on both sides of the lower surface of the mounting plate 1, and a support frame 39 is fixedly mounted on the rear surface of the mounting plate 1; like Figure 1 As shown, a reflective strip 40 is fixedly mounted on the front surface of each of the plurality of warning posts 24; like Figure 8 As shown, a brush head 41 is fixedly mounted on the rear surface of the wiping plate 33; The support feet 38 on both sides of the lower surface of the mounting plate 1 provide stable support for the entire structure, preventing the mounting plate 1 from tilting due to uneven force, and improving the stability of the device. The support frame 39 on the rear surface further enhances the installation strength of the mounting plate 1 and can cooperate with the external fixing structure to achieve overall fixation of the device and prevent displacement during use. The reflective strips 40 on the front surfaces of the multiple warning posts 24 can enhance the light reflection effect, improve the visibility of the warning posts 24 in dimly lit production environments, strengthen the warning function, and ensure that personnel or equipment can quickly identify the warning area. The brush head 41 on the rear surface of the wiper 33 is adapted to the surface of the warning post 24. When the threaded block 28 drives the wiper 33 to move, the brush head 41 can wipe the surface of the warning post 24 more thoroughly, cooperating with the wiper 33 to enhance the cleaning effect, effectively remove dust and other stains attached to the lithium carbonate production environment, and ensure the warning clarity of the warning post 24 and the reflective strip 40.
[0022] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
