Description

Technical Field

[0001] This utility model relates to the field of rockburst protection technology, and in particular to an installation structure for an energy dissipation and protection net for rockburst prevention. Background Technology

[0002] Rockburst is a common dynamic damage phenomenon in the construction of deep underground engineering projects. When the high elastic strain energy accumulated in the rock mass is greater than the energy consumed by the rock breaking, the balance of the rock mass structure is disrupted. The excess energy causes the rock to burst, causing rock fragments to peel off and fly out of the rock mass, triggering a safety incident.

[0003] The prior art patent application with publication number CN211038672U discloses a rockburst flexible protection system with an energy dissipation device, including a steel frame, transverse supports, multiple steel frames arranged at intervals, multiple transverse supports arranged on the steel frames, support ropes and energy dissipators, multiple support ropes arranged longitudinally and transversely between the steel frames and transverse supports, the support ropes being connected to one end of the energy dissipator, and the other end of the energy dissipator being connected to an anchor point on the rock wall; a protective net is laid on the longitudinal and transverse support ropes, which improves the resistance to rupture and the protection capability, and eliminates the kinetic energy on the debris.

[0004] However, in the aforementioned existing technologies, the installation of energy-consuming structures is cumbersome, which can easily increase the construction period and make it difficult to provide rapid protection. Utility Model Content

[0006] To achieve the above objectives, this utility model provides an installation structure for an energy dissipation protective net for rockburst prevention, including a frame and an energy dissipation connection unit. The energy dissipation connection unit includes a slide rail, a sliding ring seat, a fixing plate, a spring, a right-angle plate, locking bolts, a moving plate, a base plate, installation components, and support components. The energy dissipation connection unit is connected to the frame. The slide rail is fixedly connected to the frame and located on the inner wall of the frame. The sliding ring seat is slidably connected to the slide rail and located on the outer wall of the slide rail. The fixing plate is fixedly connected to the sliding ring seat and located on the outer wall of the sliding ring seat. The inner sidewall, and the fixed plate is slidably engaged with the slide rail, the spring is fixedly connected to the slide rail and the fixed plate respectively, the right angle plate is fixedly connected to the slip ring seat and is located on the outer sidewall of the slip ring seat, the locking bolt is threadedly connected to the right angle plate and is located on one side of the right angle plate, the moving plate is fixedly connected to the locking bolt and is located at one end of the locking bolt, the base plate is rotatably connected to the frame and is located below the frame, the mounting assembly is connected to the base plate, and the support assembly is connected to the base plate and the frame respectively.

[0007] The support assembly includes a base, a support rod, and a U-shaped frame. The base is fixedly connected to the frame and located on the outer side wall of the frame. The support rod is rotatably connected to the base and located on the inner side wall of the base. The U-shaped frame is detachably connected to the base plate and located above the base plate.

The expansion bolts are slidably connected to the mounting base and located on the inner sidewall of the mounting base.

[0010] The mounting assembly further includes connecting ribs, which are fixedly connected to the base plate and the mounting plate, respectively.

[0011] This utility model discloses an installation structure for an energy dissipation protective net used for rockburst prevention. In use, the four ends of the protective net are placed on the outer sides of the corresponding sliding ring seats. Rotating the locking bolts causes the moving plate to clamp the protective net with the sliding ring seats. When fragments break off from the rock mass, the protective net is subjected to an outward pulling force. At this time, the sliding ring seats slide downwards, causing the fixing plate to compress the spring. During this process, the spring stores elastic potential energy, eliminating the impact force caused by the fragments. The stored elastic potential energy also causes the sliding ring seats to quickly return to their original position, achieving efficient use of the protective net. The support assembly supports the base plate and the frame, and the installation assembly fixes the base plate. This method eliminates the impact force caused by fragments, reduces construction time, and provides effective protection. Attached Figure Description

[0021] This utility model provides an installation structure for an energy dissipation and protection net for rockburst prevention, including a frame 101 and an energy dissipation connection unit. The energy dissipation connection unit includes a slide rail 102, a sliding ring seat 103, a fixing plate 104, a spring 105, a right-angle plate 106, a locking bolt 107, a moving plate 108, a base plate 109, an installation component, and a support component.

The support assembly is connected to the base plate 109 and the frame 101 respectively.

[0023] In this embodiment, the four ends of the protective net are placed on the outside of the corresponding slip ring seat 103. The locking bolt 107 is rotated to drive the moving plate 108 to clamp the protective net with the slip ring seat 103. When the fragments break off from the rock mass, the protective net will be pulled outward.

[0025] In this embodiment, the support rod 111 is rotated to allow the U-shaped frame 112 to slide on the base plate 109, and then fixed with bolts, so that the base plate 109, the support rod 111 and the frame 101 form a triangular support structure to support the protective net.

[0026] Furthermore, the ground nail 113 is fixedly connected to the base plate 109 and is located below the base plate 109.

[0027] In this embodiment, the ground stake 113 can be embedded into the ground during installation to ensure the stability of the base plate 109.

[0029] In this embodiment, holes need to be drilled in the ground, and then the expansion bolts 116 are inserted to fix the mounting plate 114, which effectively improves the fixing effect of the ground nails 113 and avoids loosening.

[0030] Furthermore, the connecting ribs 117 are fixedly connected to the base plate 109 and the mounting plate 114 respectively.
