Description

Technical Field

[0001] This utility model relates to the field of mining technology, and more specifically, to a safety protection device for mining operations. Background Technology

[0002] In mining operations, the coordinated operation of mining machinery and transportation equipment creates a dynamic system where personnel, equipment, and complex geological environments intertwine. The drilling, blasting, and ore loading processes during mining, as well as the continuous operation of heavy vehicles and conveying equipment in the transportation phase, all expose the site to multiple risks, including mechanical injuries, falling objects, and vehicle collisions.

[0003] For example, the "Safety Protection Device for Mining" disclosed in Chinese Utility Model Patent (Publication No.: CN216361018U) includes a protective component for safety protection, stabilizing components connected to both sides of the protective component, and an adjusting and moving component connected to the side of the stabilizing component. The front end of the protective component is connected to a retracting component for providing warnings. This safety protection device for mining not only provides good protection but also has warning and moving functions.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, its movement function relies on adjusting the hydraulic rod in the moving component to drive the roller to extend and retract. The device's displacement is achieved by extending the hydraulic rod to make the roller touch the ground and the stabilizing plate levitate. This movement method requires the device to be powered on in real time to maintain the working state of the hydraulic rod. However, in the complex outdoor environment of mining, the stability of the power supply is difficult to guarantee. Once a power outage occurs or the power supply connection is difficult, the hydraulic rod will not be able to extend and retract normally, and the roller will not be able to effectively touch the ground. This makes it difficult for the device to move or relocate, which seriously limits its applicability and reliability in emergency situations or when frequent position adjustments are required.

[0005] Therefore, we have made improvements to this and proposed a safety protection device for mining operations. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a safety protection device for mining operations, solving the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A safety protection device for mining operations includes a protective frame, a support assembly at the bottom of the protective frame, and a protective net fixedly installed inside the protective frame.

[0009] The support assembly includes stabilizing plates symmetrically distributed and fixedly installed at the bottom of the protective frame. Guide plates are fixedly installed at both ends of the stabilizing plates. symmetrically distributed fixed plates are fixedly installed at the top of the stabilizing plates. A rotating shaft is rotatably installed on the inner surface of the fixed plates. An elastic telescopic rod is fixedly installed at one end of the rotating shaft. A drive shaft is fixedly installed between the telescopic ends of the two elastic telescopic rods. Rollers are rotatably installed at both ends of the drive shaft. A second slot is provided at the connection point between one end of the stabilizing plate and the guide plate. The second slot is adapted to the drive shaft. A prompting component and a positioning component are provided at the top of the protective frame.

[0010] As a preferred technical solution of this application, the warning component includes a fixed frame that is fixedly installed on the rear side of the top of the protective frame, and a warning plate is rotatably installed on the fixed frame.

[0011] As a preferred technical solution of this application, the positioning component includes a through groove opened on the top of the protective frame, an insert plate slidably inserted into the through groove, a positioning groove corresponding to the position of the insert plate opened on the warning plate, the positioning groove being adapted to the insert plate, a sliding groove opened at the bottom of the inner wall of the through groove, a slider slidably installed on the sliding groove, the slider being fixedly connected to the bottom of the insert plate, and a limit spring being fixedly installed inside the sliding groove.

[0012] As a preferred technical solution of this application, the front end of the insert plate is provided with an operation hole.

[0013] As a preferred technical solution of this application, a first slot adapted to the drive shaft is formed on the top outer surface of the guide plate.

[0014] As a preferred technical solution of this application, the top of the stabilizing plate is provided with symmetrically distributed anchoring holes.

[0015] As a preferred technical solution of this application, the guide plate is arc-shaped, and the origin of the guide plate is adapted to the rotation position of the rotating shaft and the fixed plate.

[0016] As a preferred technical solution of this application, the elastic telescopic rod comprises an outer cylinder, a telescopic rod, and a spring. The telescopic rod is slidably inserted into the outer cylinder, and the spring is fixedly installed inside the outer cylinder and fixedly connected to one end of the telescopic rod located inside the outer cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. Through the coordinated use of the protective frame, support components, protective netting, stabilizing plate, anchoring holes, guide plate, first slot, second slot, rotating shaft, fixing plate, drive shaft, elastic telescopic rod, and rollers, the rollers can be flexibly switched between their working and storage positions via manual operation: during movement, the drive shaft engages the second slot, allowing the rollers to touch the ground for quick deployment; once in place, tilting the protective frame and pulling the drive shaft causes it to slide along the guide plate and engage the first slot, completing the horizontal storage of the rollers. Subsequently, fixed stakes are driven into the anchoring holes for stable anchoring. The entire process requires no electricity, significantly improving the device's applicability and stability in complex outdoor environments.

[0020] 2. Through the coordinated use of the fixed frame, warning plate, positioning component, through slot, insert plate, positioning groove, operating hole, limit spring, slide, and slider, the warning plate can be quickly unfolded and retracted by manually operating the positioning component. In both states, the mechanical engagement between the insert plate and the positioning groove achieves stable interlocking. Compared with traditional electrically driven winding components, it is not only more economical and convenient to operate, but also completely eliminates the dependence on the power unit, significantly improving the stability and reliability of the warning unit in complex outdoor environments, ensuring continuous and effective warning of the work area.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1

[0033] Please refer to Figures 1-5 A safety protection device for mining operations includes a protective frame 1, a support component 2 at the bottom of the protective frame 1, and a protective net 3 fixedly installed inside the protective frame 1.

[0034] The support component 2 includes stabilizing plates 7 symmetrically distributed at the bottom of the protective frame 1, both ends of which are fixedly mounted with guide plates 9. Symmetrically distributed fixing plates 13 are fixedly mounted on the top of the stabilizing plate 7. A rotating shaft 12 is rotatably mounted on the inner surface of the fixing plate 13. An elastic telescopic rod 15 is fixedly mounted on one end of the rotating shaft 12. A drive shaft 14 is fixedly mounted between the telescopic ends of the two elastic telescopic rods 15. Rollers 16 are rotatably mounted on both ends of the drive shaft 14. A second slot 11 is provided at the connection point between one end of the stabilizing plate 7 and the guide plate 9. The second slot 11 is adapted to the drive shaft 14. A prompting component and a positioning component 6 are provided on the top of the protective frame 1.

[0035] Furthermore, a first slot 10 adapted to the drive shaft 14 is formed on the top outer surface of the guide plate 9. When the drive shaft 14 rotates to the horizontal storage position, it can be elastically locked into the slot to achieve stable locking, effectively preventing the roller 16 from accidentally falling off or shifting when not in operation, thus improving the reliability and safety of the roller 16 storage.

[0036] Furthermore, the top of the stabilizing plate 7 is provided with symmetrically distributed anchoring holes 8. This facilitates the even driving of fixing piles into the ground, making the distribution of fixing force between the stabilizing plate 7 and the ground more balanced, and effectively improving the overall anti-overturning ability and stability of the protective frame 1 in the working state.

[0037] Furthermore, the guide plate 9 is arc-shaped, and its origin is adapted to the rotational positions of the rotating shaft 12 and the fixed plate 13. This allows the drive shaft 14 to slide smoothly along the surface of the guide plate 9 during rotation, reducing jamming and wear, and improving the smoothness and operational accuracy of the transition between the working position and the storage position of the roller 16.

[0038] Furthermore, the elastic telescopic rod 15 comprises an outer cylinder, a telescopic rod, and a spring. The telescopic rod is slidably inserted into the outer cylinder, and the spring is fixedly installed inside the outer cylinder and fixedly connected to one end of the telescopic rod located inside the outer cylinder. This enables the elastic telescopic rod 15 to have automatic extension, retraction, and reset functions, ensuring smooth operation and stable locking of the drive shaft 14 when it is engaged or disengaged from the slot, and improving the reliability of the roller 16 in switching between its working and storage positions.

[0039] Example 2

[0040] The safety protection device for mining provided in Embodiment 1 is further optimized. Specifically, the warning component includes a fixed frame 4 fixedly installed on the top rear side of the protective frame 1, and a warning plate 5 is rotatably installed on the fixed frame 4.

[0041] Furthermore, the positioning component 6 includes a through groove 17 on the top of the protective frame 1, with an insert plate 18 slidably inserted into the through groove 17. The warning plate 5 has a positioning groove 19 corresponding to the position of the insert plate 18, and the positioning groove 19 is adapted to the insert plate 18. A sliding groove 22 is formed at the bottom of the inner wall of the through groove 17, and a slider 23 is slidably mounted on the sliding groove 22. The slider 23 is fixedly connected to the bottom of the insert plate 18, and a limit spring 21 is fixedly installed inside the sliding groove 22. This achieves mechanical locking of the warning plate 5 in its unfolded or retracted state, effectively improving the smoothness of the warning unit switching operation and the reliability of positioning.

[0042] Furthermore, the front end of the insert plate 18 is provided with an operating hole 20. This allows workers to pull the insert plate 18 using tools or by applying direct force.

[0043] The usage process of the safety protection device for mining provided by this utility model is as follows:

[0044] In use, when moving the device, the drive shaft 14 is engaged inside the second slot 11 by the elastic action of the elastic telescopic rod 15, and the rollers 16 at both ends of the drive shaft 14 are limited to the bottom of the stabilizing plate 7. At this time, the entire device relies on the rollers 16 to roll in contact with the ground, which facilitates the movement and arrangement of the device by the staff. After determining the position of the protective frame 1, the staff tilts the entire protective frame 1 in one direction to disengage a set of rollers 16 from the ground, and then pulls the drive shaft 14. The drive shaft 14 drives the telescopic end of the elastic telescopic rod 15 to extend elastically, and at the same time, the drive shaft 14 is disengaged from the second slot 11. Then, relying on the rotatable effect of the elastic telescopic rod 15 through the rotating shaft 12 and the fixed plate 13, the drive shaft 14 slides directly along the outer surface of the guide plate 9, and finally the drive shaft 14 springs back to its original position. The drive shaft 14 and rollers 16 are retracted from the vertical direction to the horizontal direction by inserting the drive shaft 14 into the first slot 10. In the same way, the other set of rollers 16 are retracted. At this time, the protective frame 1 will directly contact the ground by relying on the stabilizing plate 7. Then, the fixing pile is driven into the ground through the anchoring hole 8 to fix the protective frame 1 in the designated position. When it is necessary to move the device later, first release the fixing effect between the stabilizing plate 7 and the ground, and then adjust the drive shaft 14 from the first slot 10 to the position of the second slot 11, so that the device can be moved by rolling contact with the ground through the rollers 16. In the whole process, the conversion between the working position and the storage position of the rollers 16 is completed by manual operation without relying on the power unit drive, which significantly improves the applicability and stability of the device in complex outdoor power supply environments.

[0045] During outdoor use, to enhance the warning effect of the protective device, the operator manually pulls the insert plate 18 in the positioning component 6 to slide it on the through groove 17. The moving end of the insert plate 18 simultaneously drives the slider 23 to slide in the slide groove 22 and compress the limiting spring 21. As the insert plate 18 continues to move, its end completely exits from the positioning groove 19 on the warning plate 5. At this time, the warning plate 5 is released from the locking state of the positioning component 6. The warning plate 5 is initially stored vertically downwards on the upper back of the protective frame 1. The operator then flips the warning plate 5 upwards by 180 degrees to make it vertically upwards and unfolds it, and then releases the insert plate 18. The force applied causes the limiting spring 21 to use its elastic reset effect to drive the insert plate 18 to slide in the opposite direction on the through groove 17 and re-insert it into the positioning groove 19 on the warning plate 5, thereby locking the position of the warning plate 5 in the unfolded state and ensuring the structural stability of the warning plate 5 after unfolding. Compared with the existing technology that relies on electric drive for winding components and lacks logical interlocking function, the warning plate 5 and its cooperating positioning component 6 can achieve mechanical interlocking through manual operation in both the folded and unfolded states. This not only makes the operation more economical and convenient, but also significantly improves the stability and reliability of the warning unit in complex outdoor environments, ensuring a continuous and effective warning effect on the surrounding area of ​​the work area.
