[0039] Example 1
[0040] like Figures 1-5 As shown, a safety protection device for preventing rockfall collisions during mine blasting includes a walking base 1. Specifically, the walking base 1 includes a U-shaped frame section (with several steel rods 11 slidably mounted on the U-shaped frame section and anchored to the ground; when the entire device is pushed to the vicinity of the equipment, the steel rods 11 are driven into the ground for anchoring). Several rollers 12 are respectively installed on the front and rear side walls of the U-shaped frame section. This method allows for easy pushing of the entire device, enabling it to be flexibly positioned around the working equipment facing the blasting location, effectively blocking flying rocks and rockfalls.
[0041] The top of the aforementioned walking base 1 is hinged to an anti-gangue impact mechanism, which includes a protective frame and a spring mesh structure fixedly connected inside the protective frame.
[0042] By utilizing the characteristics of the spring mesh structure that allow for easy elastic deformation and reset, protection can be achieved through the spring mesh structure during operation.
[0043] Specifically, the spring net structure includes a plurality of longitudinally arranged longitudinal springs 33, and a plurality of transversely arranged transverse springs 32, and the anchor is anchored at the intersection of the longitudinal springs 33 and the transverse springs 32. The longitudinal springs 33 and the transverse springs 32 are kept in a straight state.
[0044] At the same time, in order to increase the structural strength of the spring net structure formed by the transverse springs 32 and the longitudinal springs 33, and the impact resistance of flying stones and gangues, a plurality of anchors 6 are installed on the spring net structure to increase the structural strength of the spring net.
[0045] The anchor 6 is achieved along the intersection of the transverse springs 32 and the longitudinal springs 33. Specifically, the anchor 6 includes a cross anchor pipe, which includes a pair of cross half anchor pipes spliced together (i.e. the cross anchor pipe is formed by splicing a first cross half anchor pipe 61 and a second cross half anchor pipe 62 together); the transverse springs 32 and the longitudinal springs 33 pass through the cross anchor pipe.
[0046] Through the limiting action of the cross anchor pipe, the transverse springs 32 and the longitudinal springs 33 are anchored at multiple points by the anchor 6 during operation. When flying stones and gangues hit the net structure, the net structure is not easily deformed due to the multiple anchor points. At the same time, the reset feature of the spring after deformation can also restore the net structure. At the same time, the deformation of the spring produces a buffer, which can fully reduce the kinetic energy of the flying stones.
[0047] By this way, the stability of the net structure is maintained, the service life of the net structure is provided, and the impact force of flying stones and gangues with large kinetic energy is resisted to protect the equipment.
[0048] The left and right ends of the cross anchor pipe are respectively provided with locking structures, and the cross half anchor pipes are locked after being combined by the locking structures. Specifically, the locking structure includes a threaded locking ring 63, and a threaded structure is formed on the outer wall of the cross half anchor pipe, and the threaded locking ring 63 is threadedly connected to the threaded structure.
[0049] That is, after the cross half anchor pipes are combined and clamped into the intersection points of the transverse springs 32 and the longitudinal springs 33, the threaded locking ring is threadedly fastened between the cross half anchor pipes (the threaded locking ring 63 is pre-sleeved on the spring and then clamped to the cross half anchor pipes during the threaded fastening process).
[0050] Embodiment 2
[0051] As Figures 1-5As shown, in this embodiment, based on the structure of embodiment 1, long fixed arms 2 are respectively hinged to the upper ends of both sides of the above-mentioned protective frame 31. The long fixed arms 2 are fixedly connected to the walking base 1 (specifically, the long fixed arms 2 are fixedly connected to the top of the U-shaped frame).
[0052] Meanwhile, hydraulic cylinders 51 are hinged to the lower ends of both sides of the protective frame 31. Specifically, the cylinder of the hydraulic cylinder 51 is hinged to the U-shaped frame, and the piston rod of the hydraulic cylinder 51 is fixedly connected to a hinge seat 52, which is hinged to the lower end of the side wall of the protective frame 31.
[0053] During operation, when the hydraulic cylinders 51 on both sides push the protective frame 31, the protective frame 31 rotates at an angle. During this process, the protective frame 31 rotates relative to the long fixed arm 2. By rotating and adjusting the protective frame 31, the angle can be adjusted according to the flight trajectory of the flying stone, so as to catch the flying stone and gangue. In this way, the blocking effect of flying stone is greatly improved.
[0054] Example 3
[0055] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, an inner baffle mechanism is fixedly connected to the inner side of the aforementioned protective frame 31. This inner baffle mechanism provides secondary protection.
[0056] Specifically, the inner barrier mechanism includes a barrier frame 4, within which a wire mesh 41 is fixedly connected. Connecting plates 411 are detachably installed on both the top and bottom sides of the barrier frame 4, and these connecting plates 411 are fixedly mounted on the protective frame 31. The wire mesh 41 serves as the final layer of protection; specifically, after the spring mesh structure significantly reduces the kinetic energy of the flying stones, the wire mesh acts as the final line of defense.
[0057] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
