[0029] Embodiment
[0030] Reference Figures 1-4 For the embodiment of the present application, the embodiment provides a step blasting construction protective fence device, comprising,
[0031] The protection mechanism 100 comprises a support column 101, a protective net plate 102 fixedly installed on the outer side of the support column 101, and a positioning assembly 103 arranged at the upper and lower ends of the support column 101.
[0032] The buffer mechanism 200 comprises a positioning base 201 fixedly installed at the bottom of the protective net plate 102, a support slot rod 202 hingedly installed on the outer side of the positioning base 201, and a support buffer assembly 203 arranged at the bottom of the support slot rod 202.
[0033] And the auxiliary shielding mechanism 300 used in cooperation with the protection mechanism 100.
[0034] Among them, the protection mechanism 100 can effectively enhance the overall stability of the fence device through the fixed installation of the support column 101 and the protective net plate 102, and the arrangement of the positioning assembly 103. The L-shaped bent plate 103a, the bolt 103b, the positioning block 103c and the clamping block 103d in the positioning assembly 103 adopt a multiple fastening mode, which can resist the strong vibration and impact generated in the blasting operation.
[0035] Specifically, the protection mechanism 100 further comprises a limiting guide rail 104 fixedly installed on the outer side of the support column 101, and a threaded hole 105 opened on the outer side of the limiting guide rail 104.
[0036] Among them, the limiting guide rail 104 and the threaded hole 105 provide a stable sliding track and a fixed point for the adjusting sliding sleeve 301 of the auxiliary shielding mechanism 300. The limiting guide rail 104 ensures that the adjusting sliding sleeve 301 remains stable during the up and down movement, and the threaded hole 105 provides fixed support to prevent slipping or loosening due to vibration, thereby enhancing the stability of the overall structure.
[0037] Further, the buffer mechanism 200 further comprises a damping vibration reduction spring 204 fixedly installed at the bottom of the support slot rod 202, and a connecting cross plate 205 fixedly installed at the bottom of the damping vibration reduction spring 204.
[0038] The buffer mechanism 200 can effectively absorb and disperse the blasting impact force through the cooperation of the positioning base 201, the support groove rod 202 and the support buffer assembly 203. The adjusting plate 203a, the buffer spring 203c, the buffer partition plate 203d and the bottom plate 203e in the support buffer assembly 203 form a multi-layer buffer structure, which further enhances the impact resistance of the equipment in combination with the damping vibration spring 204 and the connecting cross plate 205, prevents local deformation or damage, prolongs the service life of the equipment, and reduces the maintenance and repair cost.

The adjusting plate 203a and the positioning hole 203b provide height adjustment function. The buffer spring 203c and the buffer partition plate 203d further absorb impact energy. The bottom plate 203e and the arc-shaped groove 203f ensure the stability of the buffer assembly under impact, preventing local deformation or damage.
[0041] Further, the auxiliary shielding mechanism 300 includes an adjusting sleeve 301 movably sleeved outside the limiting guide rail 104, a screw rod 302 screwedly installed outside the adjusting sleeve 301, and a damping adjusting piece 303 arranged outside the adjusting sleeve 301. The auxiliary shielding mechanism 300 further includes a connecting rod 304 fixedly installed outside the damping adjusting piece 303, a shielding plate 305 fixedly installed outside the connecting rod 304, and a mounting plate 306 movably installed outside the shielding plate 305.
[0042] The auxiliary shielding mechanism 300 can be flexibly unfolded to increase the protection area through the design of the damping adjusting piece 303 and the adjusting sleeve 301, and can move up and down through the limiting guide rail 104 to adapt to the needs of different blasting scenes.
[0043] Further, the damping adjusting piece 303 includes a gear groove cylinder 303a fixedly installed outside the adjusting sleeve 301, and a rotating rod 303b rotatably installed in the inner cavity of the gear groove cylinder 303a. The damping adjusting piece 303 further includes a plurality of gear teeth 303c fixedly installed outside the rotating rod 303b in an annular arrangement, and a connecting block 303d fixedly installed at the top of the rotating rod 303b.
[0044] The tooth groove cylinder 303a, the rotating rod 303b and the teeth 303c in the damping adjusting part 303 provide stable damping adjustment function, ensure that the shielding plate 305 remains stable during unfolding and movement, avoid loosening or deviation due to vibration, and further enhance the protection effect; the damping adjusting part 303 provides stable damping adjustment function through cooperation of the tooth groove cylinder 303a, the rotating rod 303b and the teeth 303c, ensures that the shielding plate 305 remains stable during unfolding and movement; the tooth groove cylinder 303a and the teeth 303c form a meshing structure, the rotating rod 303b and the connecting block 303d realize precise adjustment, avoid loosening or deviation due to vibration, and improve the reliability and protection effect of the auxiliary shielding mechanism 300.
[0045] Further, the positioning assembly 103 includes an L-shaped bent plate 103a fixedly installed outside the support column 101, a bolt 103b screwedly installed outside the L-shaped bent plate 103a, a positioning block 103c fixedly installed outside the L-shaped bent plate 103a, and a clamping block 103d fixedly installed outside the L-shaped bent plate 103a.
[0046] The positioning assembly 103 forms a multiple fastening structure through cooperation of the L-shaped bent plate 103a, the bolt 103b, the positioning block 103c and the clamping block 103d, can effectively enhance the connection stability between the support column 101 and the protective net plate 102, the L-shaped bent plate 103a and the bolt 103b provide rigid connection, and the positioning block 103c and the clamping block 103d further limit displacement to prevent loosening due to vibration or impact, and ensure that the surrounding device remains stable during blasting operation.
[0047] In use, in bench blasting construction, the protection mechanism 100 first forms a basic protection barrier through the support column 101 and the protective net plate 102, and the positioning assembly 103 ensures that the connecting part is stable and prevents loosening due to vibration;
[0048] The buffer mechanism 200 absorbs blasting impact force through the supporting buffer assembly 203 and the damping vibration reduction spring 204, and protects the equipment from damage;
[0049] The auxiliary shielding mechanism 300 moves the adjusting sleeve 301 on the limiting guide rail 104, and unfolds the shielding plate 305 by using the damping adjusting part 303 to expand the protection range.
[0050] In summary, through the cooperative design of the protection mechanism 100, the buffer mechanism 200 and the auxiliary shielding mechanism 300, the strong vibration and impact generated in the blasting operation can be effectively responded. The protection mechanism 100 enhances the overall stability through the multiple fastening structures of the support column 101, the protection net plate 102 and the positioning assembly 103, and prevents the loosening of the connecting parts. The buffer mechanism 200 absorbs and disperses the impact force through the multi-layer buffer design of the support buffer assembly 203 and the damping vibration spring 204, and avoids deformation or damage of the equipment. The auxiliary shielding mechanism 300 expands the protection area and adapts to different scene requirements through the flexible adjustment function of the damping adjustment part 303 and the adjustment sliding sleeve 301.
