Technical Field

[0001] This utility model relates to the field of open-pit mining technology, specifically to a retaining and protective device for slope blasting in open-pit mines. Background Technology

[0002] An open-pit mine is an area where mineral resources are mined using open-pit mining methods. The mining targets generally include coal, copper, gold, and sand and gravel. When mining in an open-pit mine, the slopes are blasted. To ensure safety, protective barriers are set up around the blasting point. There are various types of protective barriers on the market for slope blasting in open-pit mines.

[0003] However, based on existing solutions and actual usage, the current protective barriers used for slope blasting in open-pit mines are not tall enough, making it inconvenient to shield against dust or small debris generated during blasting, resulting in significant environmental pollution. Furthermore, they are inconvenient to install and dismantle, and assembly is cumbersome. It is also inconvenient to flexibly adjust the angle between barriers as needed. Therefore, we propose a protective barrier for slope blasting in open-pit mines to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a protective enclosure for blasting slopes in open-pit mines, in order to solve the problems mentioned in the background art, such as insufficient height of the current protective enclosures for blasting slopes in open-pit mines, inconvenience in shielding dust or small debris generated during blasting, significant environmental pollution, inconvenience in installation and disassembly, cumbersome assembly, and inconvenience in flexibly adjusting the angle between enclosures as needed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective enclosure for blasting slopes in open-pit mines, comprising:

[0006] The enclosure panel has a support frame fixed to its rear side, and the support frames are arranged symmetrically on the left and right sides.

[0007] Also includes:

[0008] The enclosure is equipped with a shielding mechanism above it to reduce dust and debris splashing, and the shielding mechanism is housed inside the enclosure.

[0026] 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a protective enclosure for blasting slopes in open-pit mines, comprising: enclosure plate 1, support frame 2, support rod 3, positioning bolt 4, support frame 5, winding roller 6, connecting wheel 7, adjusting wheel 8, handle 9, positioning rod 10, shielding cloth 11, fixing block 12, mounting rod 13, support spring 14, and limiting block 15;

[0028] First, as attached Figure 1 As shown, a support frame 2 is fixed to the rear side of the enclosure 1. The support frame 2 is installed on the ground with bolts. The support frames 2 are symmetrically arranged on the left and right sides to effectively support the enclosure 1. A shielding mechanism to reduce dust and debris splashing is provided above the enclosure 1. The height of the shielding mechanism can be adjusted to shield small debris splashed during blasting to prevent debris from injuring people. Rotatable connecting mechanisms are provided on the left and right sides of the rear side of the enclosure 1. The enclosure 1 is assembled through the connecting mechanisms.

[0029] As attached Figure 1 and attached Figure 2As shown, the inner thread of the enclosure plate 1 is connected to the positioning bolt 4. Remove the positioning bolt 4 from the enclosure plate 1 to disengage the positioning bolt 4 from the threaded connection with the support rod 3, and pull the support frame 5 upward. The support rod 3 is fixed to the lower outer side of the support frame 5, allowing the support rod 3 to slide inside the enclosure plate 1. The longitudinal section of the support rod 3 is a "T" shaped structure to ensure stability. Adjust the support frame 5 to a suitable height, and then reconnect the positioning bolt 4 to the enclosure plate 1. The positioning bolts 4 are symmetrically arranged, so that the upper positioning bolt 4 is threadedly connected to the support rod 3, and the lower positioning bolt 4 supports the support rod 3.

[0030] As attached Figure 2 and attached Figure 3 As shown, the shielding mechanism includes a support rod 3, a positioning bolt 4, a support frame 5, a winding roller 6, and a shielding cloth 11. A handle 9 is fixed above the adjusting wheel 8. A positioning rod 10 is connected to the internal slot of the handle 9. Pulling the positioning rod 10 upward causes it to disengage from the handle 9. Then, rotating the handle 9 causes the adjusting wheel 8 to rotate. A connecting wheel 7 is engaged with the outer side of the adjusting wheel 8. The adjusting wheel 8 causes the connecting wheel 7 to rotate. The connecting wheel 7 is fixed to the winding roller 6. The connecting wheel 7 causes the winding roller 6 to rotate within the support frame 5. Adjusting the angle of the winding roller 6 causes the shielding cloth 11 to be wound around the outer side of the winding roller 6. This releases the shielding cloth 11, which shields small debris generated during the explosion, preventing the flying debris from injuring people. The shielding cloth 11 is a flexible shield with a certain weight and toughness, which can buffer the impact force and prevent debris from damaging the device.

[0031] As attached Figure 2 Appendix Figure 4 and attached Figure 5 As shown, a fixing block 12 is fixed to the rear exterior of the enclosure 1. When two enclosures 1 are placed together, a limiting block 15 is slidably connected to the inside of the mounting rod 13 through a support spring 14. Pressing the limiting block 15 inward compresses the support spring 14, causing the limiting block 15 to retract into the mounting rod 13. Then, the mounting rod 13 is inserted into the fixing block 12, so that the fixing block 12 and the mounting rod 13 are connected by a slot. The longitudinal section of the mounting rod 13 is an "n"-shaped structure, which can effectively connect the two fixing blocks 12 and limit the enclosure 1. After the mounting rod 13 is inserted into the fixing block 12, the elasticity of the support spring 14 pushes the limiting block 15 to reset, causing the outer end of the limiting block 15 to pop out of the mounting rod 13, thus limiting the fixing block 12 and fixing the enclosure 1.

[0032] This is the entire working process of the enclosure protection device used for slope blasting in open-pit mines. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
