Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-4 One embodiment provided by this utility model:

[0025] A protective structure for slope blasting construction includes a protective frame 100. A protective inner cloth 110 is installed on the inner side of the protective frame 100. The protective frame 100 is assembled by splicing two sets of frame horizontal bars 120 and frame vertical bars 130 in sequence from top to bottom and left to right. The frame horizontal bars 120 and frame vertical bars 130 are assembled in the same way. Inner insert components 140 are evenly installed at equal intervals at the corners and rear edges of the protective frame 100. Auxiliary ropes 150 are cross-attached on the outer side of the protective inner cloth 110. The side of the protective inner cloth 110 is connected to the inner side of the protective frame 100 by a hanging buckle component 160.

[0026] As described in more detail in this embodiment, the frame crossbar 120 includes an assembly support rod 121. Assembly side rings 122 are symmetrically fixed on both sides of the assembly support rod 121, and assembly pull rings 123 corresponding to the hook assembly 160 and auxiliary rope 150 are uniformly and equidistantly fixed on the inner outer wall of the assembly support rod 121. This facilitates the docking of two adjacent sets of assembly support rods 121 and the fixing of the hook assembly 160, which is convenient for subsequent use. Support rods 124 are horizontally supported on both sides of the assembly support rod 121, and the outer end of the support rod 124 is fixed to the assembly side ring 122. The assembly support rod 121 is hollow inside, which facilitates the insertion and assembly of the assembly pull rings 123 and the weight reduction of the assembly support rod 121. At the same time, the interior can also be reinforced by inserting corresponding ropes, which is convenient for subsequent use.

[0027] As described in more detail in this embodiment, the insert assembly 140 includes a ground insertion cylinder rod 141, and a mounting top plate 142 is integrally fixed to the outer end of the ground insertion cylinder rod 141. A limiting pin 143 is inserted into the side of the mounting top plate 142. The limiting pin 143 is inserted and assembled in the middle of two sets of adjacent mating assembly rings 122, and the outer end of the limiting pin 143 is fastened by a fastening nut 144. An inner insertion tip 146 is provided at the end of the ground insertion cylinder rod 141 away from the mounting top plate 142. Thus, during assembly and use, it is convenient to connect the ground insertion cylinder rod 141 with the frame crossbar 120 and the frame vertical bar. The limiting support assembly at the side joint and corner of 130 is provided. The internal thread of the ground insertion cylinder 141 is provided with a fine-adjustment inner post 145, and the outer end of the fine-adjustment inner post 145 is fixed with the inner insertion tip 146. The external thread of the fine-adjustment inner post 145 is provided with a support nut 147, and the support nut 147 is supported on the outer end of the ground insertion cylinder 141. The inner insertion tip 146 has corresponding side flat edges 148 on both sides. In this way, during assembly and use, it is convenient to expand the support of the ground insertion cylinder 141 according to the use needs, so that it is easier to insert and fix it more deeply in the ground, and the assembly and use are more stable.

[0028] As described in more detail in this embodiment, the auxiliary rope 150 includes a first rope 151 and a second rope 152, which are arranged crosswise. A middle knot 153 is fixed in the middle of the first rope 151 and the second rope 152. The outer ends of the first rope 151 and the second rope 152 are respectively inserted through the inside of the assembly pull ring 123, and the corresponding assembly pull ring 123 is located at the corner of the protective frame 100. This facilitates the reinforcement and maintenance of the outer side of the protective inner cloth 110 during assembly and use, and facilitates subsequent stable use. The external cross-binding of the auxiliary rope 150 facilitates the bearing of the impact force of the auxiliary protective inner cloth 110 bearing the internal broken stones and soil.

[0029] As described in more detail in this embodiment, the hook assembly 160 includes a hook body 161, which is hooked to the side of the protective inner fabric 110. The hook body 161 away from the protective inner fabric 110 is bolted to an assembly arm 162, which is sleeved and assembled on the outer wall of the assembly pull ring 123. An anti-detachment baffle 163 is provided on the inner side of the hook tip of the hook body 161, and the anti-detachment baffle 163 is hinged to the outer end of the hook body 161. Thus, during assembly and use, it is convenient to assemble and connect the hook assembly 160, making it easy to install and disassemble as needed.

[0030] As described in more detail in this embodiment, the protective inner fabric 110 has side hook holes 111 corresponding to the hook assembly 160 on all four sides, and a metal locking ring 112 is inlaid and fitted inside the side hook holes 111. This facilitates the auxiliary hooking of the protective inner fabric 110 and the maintenance of the inner wall of the side hook holes 111. It also facilitates the bearing of tensile force with the cooperation of the metal locking ring 112, making subsequent use more stable.

[0031] Working principle: During assembly and use, based on on-site needs and predictions, a protective inner fabric 110 of appropriate size is carried, and then a corresponding number of assembly support rods 121 are transported to the site. These are combined to form a protective frame 100 of the same size as the protective inner fabric 110. During assembly and docking, the adjacent sets of assembly edge rings 122 are assisted in being positioned and bounded by the limiting pins 143 and the fastening nuts 144. Then, with the cooperation of the assembly arm 162 and the hook body 161, they are assisted in being assembled into the assembly pull ring 123. Further, with the cooperation of the hook body 161 and the anti-detachment baffle 163, the hooks pass through the side hook holes 111 and the metal locking ring 11. The protective inner fabric 110 is then connected and assembled with the 2nd component. Subsequently, according to the corresponding geological cutting requirements, the ground-inserting cylinder 141 is extended and adjusted with the help of the fine-tuning inner column 145 to facilitate the subsequent insertion of the ground-inserting cylinder 141 into the slope, which facilitates the limiting support assembly of the protective frame 100. This facilitates the blasting maintenance of the corresponding area. At the same time, the auxiliary rope 150 is assembled on the outside of the protective inner fabric 110 as needed to facilitate the auxiliary maintenance of the protective inner fabric 110. This makes it easier to reduce dust and falling rocks and soil by covering the protective inner fabric 110 and the protective frame 100 during use, which is conducive to construction safety and environmental protection. The operation ends here.
