Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-5As shown, this utility model provides a technical solution: a rockfall prevention cover structure for ore transport vehicles, including a cargo box 1, an axle base 2 below the cargo box 1, two connecting pads fixedly mounted on the top surface of the axle base 2, the top of the rear connecting pads being hinged to the bottom of the cargo box 1 via bearings, a hydraulic telescopic rod 3 movably mounted on the top surface of the left side of the axle base 2, the output shaft of the hydraulic telescopic rod 3 being fixedly connected to the bottom surface of the top support block 15, the right side of the top support block 15 being fixedly welded to the left side of the cargo box 1, two support frame plates 4 fixedly mounted on the left side of the cargo box 1, a take-up and release cylinder 6 rotatably mounted between the two support frame plates 4, a stepper motor 5 fixedly mounted on the front of the front support frame plate 4, the output shaft of the stepper motor 5 being fixedly connected to the end face of the take-up and release cylinder 6, and the stepper motor 5 being fixedly mounted on the front of the front support frame plate 4. A protective net 7 is wrapped around the surface of the stepper motor 5. The stepper motor 5 and the take-up / delivery drum 6 allow the stepper motor 5 to control the rotation of the take-up / delivery drum 6, and the rotation of the take-up / delivery drum 6 controls the take-up and delivery of the protective net 7. A head pull plate 19 is fixedly installed at the right end of the protective net 7. L-shaped connecting pipes 18 are fixedly installed on both the front and back of the head pull plate 19. Threaded linkage rods 8 are installed at the front and rear of the cargo box 1. The two threaded linkage rods 8 are symmetrically distributed around the middle of the cargo box 1. The two ends of the threaded linkage rods 8 are rotatably connected to the inner walls of the left and right pad ring blocks 9 and 11, respectively. The sides of the left and right pad ring blocks 9 and 11 are connected to the cargo box 1. A servo motor 10 is fixedly installed on the left side of the left-side washer block 9. The output shaft of the servo motor 10 is fixedly connected to the left end of the threaded linkage rod 8. A displacement internal threaded sleeve 12 is threadedly fitted onto the surface of the threaded linkage rod 8. A support sliding sleeve 13 is fixedly connected to the top of the displacement internal threaded sleeve 12. The inner wall of the support sliding sleeve 13 is slidably fitted onto the surface of the support steel slide tube 14. Through the arrangement of the threaded linkage rod 8, the servo motor 10, the displacement internal threaded sleeve 12, and the support sliding sleeve 13, the threaded linkage rod 8 driven by the servo motor 10 rotates. Utilizing the threaded displacement of the threaded linkage rod 8 and the displacement internal threaded sleeve 12, and in conjunction with the support sliding sleeve 13, the slide tube 14 can slide and move on the support steel slide tube 14, while also constraining its position. The rotation of the internal threaded sleeve 12 controls its horizontal displacement. This displacement, in turn, causes the supporting sliding sleeve 13 to slide horizontally on the surface of the supporting steel sliding tube 14. With the help of the supporting frame rod 16 and the telescopic inner rod 17, the head pull pad 19 at the right end of the protective net 7 is pulled to the right, thus pulling the first end of the protective net 7 to the right, allowing it to be laid on the top of the cargo box 1. Both ends of the supporting steel sliding tube 14 are fixedly connected to the surface of the cargo box 1. The two supporting steel sliding tubes 14 are symmetrically distributed around the middle of the cargo box 1. Supporting frame rods 16 are fixedly installed on the top of both supporting sliding sleeves 13, and telescopic inner rods 17 are inserted into the top of the supporting frame rods 16.Two telescopic inner rods 17 are symmetrically distributed front and back around the center of the head pull pad 19. The ends of the two telescopic inner rods 17 are fixedly connected to two L-bend connecting pipes 18. The surface of the telescopic inner rod 17 is provided with threaded grooves, and a pusher drum 20 is threadedly sleeved on the surface of the telescopic inner rod 17. The side edge of the pusher drum 20 is rotatably connected to the top edge of the support frame rod 16. Through the arrangement of the telescopic inner rods 17 and the pusher drum 20, after the pusher drum 20 rotates, the threaded displacement principle of the pusher drum 20 and the telescopic inner rod 17 is used to drive the telescopic inner rod 17 to telescopically extend and extend outward inside the support frame rod 16, thereby adjusting the height of the right end of the protective net 7 so that it can be adjusted according to... The inclined angle of the protective netting 7 laid on the top opening of the cargo box 1 is adjusted according to demand. A protrusion 21 is fixedly installed on the front of the support frame rod 16. A fastening screw 22 passes through the middle of the protrusion 21, and the surface of the fastening screw 22 is threadedly connected to the inner wall of the protrusion 21. A resistance pressure pad 23 is fixedly connected to the end of the fastening screw 22. Through the arrangement of the push-up turntable cylinder 20, the protrusion 21, the fastening screw 22, and the resistance pressure pad 23, the threaded push principle of the fastening screw 22 drives the resistance pressure pad 23 to push against the edge of the push-up turntable cylinder 20, thus constraining the rotation of the push-up turntable cylinder 20 and improving the stability of its telescopic inner rod 17 after telescopic positioning within the support frame rod 16.

[0015] In use, first, the servo motors 10 set at the front and rear are started, and the stepper motor 5 is started simultaneously. At this time, the threaded linkage rod 8 driven by the servo motor 10 rotates. Utilizing the threaded displacement of the threaded linkage rod 8 and the internal threaded sleeve 12, the supporting sliding sleeve 13 is driven to slide horizontally to the right on the surface of the supporting steel sliding tube 14. This causes the head pull pad 19 set at the right end of the protective net 7 to be pulled to the right. Since the rotation of the take-up and release cylinder 6 is controlled synchronously by the stepper motor 5, it is used to feed and release the protective net 7, so that the protective net 7 is stably laid to the right on the top opening of the cargo box 1, sealing the top opening of the cargo box 1. When it is necessary to unload ore, similarly, the servo motor 10 drives the threaded linkage rod 8 to rotate in the opposite direction, and the stepper motor 5 synchronously controls the reverse rotation of the take-up and release cylinder 6 to... The protective net 7 is retracted and wrapped around the surface of the take-up and put-down cylinder 6 until the supporting sliding sleeve 13 is moved to the leftmost limit end on the left side. At the same time, when it is necessary to adjust the laying angle of the protective net 7 at the top opening of the cargo box 1, the fastening screw 22 is rotated to loosen the contact between the resistance pressure pad 23 and the push turntable cylinder 20. Then the push turntable cylinder 20 can be rotated. Using the thread displacement principle of the push turntable cylinder 20 and the telescopic inner rod 17, the telescopic inner rod 17 is driven to extend and retract outward inside the support frame rod 16, so as to adjust the height of the right end of the protective net 7. This allows the tilt angle of the protective net 7 laid at the top opening of the cargo box 1 to be adjusted according to the usage requirements, so as to achieve smoother operation. At the same time, the contents not described in detail in this specification are all existing technologies known to those skilled in the art.

[0016] In summary, the rockfall prevention cover structure for ore transport vehicles utilizes the servo motors 10 at the front and rear, which drive two threaded linkage rods 8 to rotate at the same speed. The threaded displacement of the threaded linkage rods 8 and the displacement inner threaded sleeve 12 causes the supporting sliding sleeve 13 to slide horizontally to the right on the surface of the supporting steel sliding tube 14. Furthermore, the support frame rod 16 and the telescopic inner rod 17 pull the head pull pad 19 at the right end of the protective net 7 to the right, effectively pulling the first end of the protective net 7 to the right. This, combined with the stepper motor synchronously controlling the rotation of the take-up and release cylinder 6, allows the protective net 7 to be laid stably and quickly on the top of the cargo box 1, effectively reducing the risk of ore falling from the top of the cargo box 1 during transportation and improving operational safety.
