Description

Technical Field

[0001] The utility model relates to the technical field of mine safety construction measures. Background Art

[0002] During the construction of a mine, a large number of blasting operations are required. To ensure construction safety, guardrails need to be erected between the construction area and the safety area. That is, the safety area and the construction area are isolated by guardrails to prohibit the entry of non-relevant personnel.

[0003] At present, this technical means uses cordons or simple protective fences for isolation, and there is a problem of non-related construction workers accidentally entering the construction area.

[0004] For example, the Hefei Design and Research Institute of Coal Industry has developed a mine construction safety guardrail, patent publication number CN219218746U. This guardrail includes a base plate, which is internally provided with a drive mechanism and a lifting mechanism. The drive mechanism includes a rotating rod, the rear end of which is provided with a conical driving wheel. The left side of the conical driving wheel is meshed with a first conical driven wheel, and the center of the first conical driven wheel is provided with a rotating shaft. The lifting mechanism includes two second conical driven wheels, and the two second conical driven wheels are respectively provided at the left and right ends of the rotating shaft. The provided drive mechanism and lifting mechanism can adjust the height of the second guardrail, thereby adapting to different protection conditions in mines and having a wider range of applications. There is no gap between the guardrail and the base plate, which prevents falling rocks from sliding through the gap between the base plate and the guardrail onto the road in front of the guardrail. However, this structure requires a drive structure and a lifting mechanism, which is complex, has high maintenance costs, and is less practical. Utility Model Content

[0034] In conjunction with the instructions Figure 1 To the attached Figure 4 This implementation process is explained in detail.

[0035] First, a reinforced concrete ground beam 100 with a height of about 0.4 to 0.6 meters is built near the toe of the slope. The ground beam adopts a wet formwork cast-in-place construction process, and ground anchor bolts 110 are implanted in the mine. The upper part of the ground anchor bolt is located inside the ground beam and is tied to the internal steel cage to form a whole. The ground beam can resist the occurrence of hazards such as rolling stones caused by blasting at the slope.

[0036] Furthermore, a passage 120 is reserved on the ground beam, which is flush with the ground and is used as a passage for wild animals, so that wild animals can pass through. In order to prevent people from drilling and climbing, the size of the passage is designed to be smaller, for example 30 cm * 30 cm.

[0037] Mounted on the ground beam 100 is a mechanically removable guardrail 200. Specifically, the guardrail is a steel structure that utilizes a prefabricated installation method for rapid assembly and installation. The guardrail comprises columns 210, a crossbeam 220, a tempered glass frame 230, steel cables 240, and a steel mesh 250. The columns are I-beams, the primary load-bearing components, exhibiting sufficient mechanical properties, including but not limited to rigidity and deflection. The crossbeam 220 comprises three sections: upper, middle, and lower. From bottom to top, they are identified as a first crossbeam 221, a second crossbeam 222, and a third crossbeam 223. These three sections are positioned between the two columns and divide the vertical space of the guardrail into a first installation area 211, a second installation area 212, and a third installation area 213. A thin stainless steel plate is welded to the first installation area. This plate is welded to the columns and the first and second crossbeams on all sides, sealing this area and forming a solid wall.

[0038] The first crossbeam 221 is an angle steel with an L-shaped cross section, and bolt holes are reserved on the first crossbeam, and the first crossbeam is fixedly connected to the ground beam by expansion bolts.

[0039] The second crossbeam and the third crossbeam are channel steels and are arranged opposite to each other to form a second installation area.

[0040] The height range of the above-mentioned second installation area 212 is between 1.5 meters and 1.9 meters, that is, the low point of the second area is about 1.5 meters and the high point is about 1.9 meters. The second installation area is installed with a tempered glass group frame 230. The tempered glass group frame is a rectangular frame composed of an aluminum alloy outer frame 231 and tempered glass 232. The tempered glass group frame is installed in the second installation area between the two columns and is fixed with an angle steel profile 233 and screws. After fixation, the second installation area forms a transparent effect. Adults can easily observe the safety status of the construction area when standing, and the protective effect of the tempered glass can ensure safety.

[0041] The third installation area 213 is located between the top ends of the columns. A stainless steel wire mesh 250 is installed in this area. Both sides of the wire mesh are mechanically fixed to the columns on both sides using fasteners. The maximum mesh size of the wire mesh is no more than 1 cm.

[0042] A plurality of steel cable holes are provided on the columns where the second installation area and the third installation area are located. The steel cable 240 passes through the above-mentioned columns and is clamped using a steel cable lock 241. The steel cable lock is a commonly used fastener, also called a steel cable anchor. The outermost section of the steel cable 240 is fixed to the above-mentioned ground beam using a ground anchor to form multiple protections.

[0043] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements to the present invention by relevant technical personnel in this field should fall within the scope of protection determined by the claims of the present invention.
