Description

Technical Field

[0001] This utility model relates to the field of geological disaster prevention and control technology, specifically a geological disaster prevention and control device for removing dangerous rocks. Background Technology

[0002] In the field of geological disaster prevention and control, unstable rocks, which are loose and suspended rocks in areas such as slopes and mountains, are the core hidden dangers that threaten road traffic, village and town safety, and engineering construction. Unstable rocks are prone to sudden falls due to weathering, rain erosion, or vibration. At best, they can block traffic; at worst, they can destroy buildings and cause casualties. Therefore, timely removal of unstable rocks is a key link in geological disaster prevention and control.

[0003] Currently, when dealing with dangerous rocks, personnel must climb to the slope or cliff where the rock is located, insert a crowbar into the gap at close range, and pry the rock using the lever principle. The force exerted by the crowbar depends on human strength, which is limited by the physical strength of the personnel. For dangerous rocks at high altitudes, personnel need to use ladders and ropes to operate in the air, which has poor stability. For dangerous rocks with large inclination angles, it is difficult for the crowbar to find an effective fulcrum, and it is easy to slip and pry without lifting the crowbar. Therefore, there is a problem that it is not convenient to remove dangerous rocks in different scenarios.

[0004] Therefore, this utility model provides a geological disaster prevention and control device for removing dangerous rocks to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a geological disaster prevention and control device for removing dangerous rocks, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a geological disaster prevention and control device for removing dangerous rocks, comprising an air pump body, an expansion mechanism fixedly connected to the air outlet of the air pump body, a telescopic mechanism fixedly connected to the outer surface of the expansion mechanism, the expansion mechanism including a high-pressure pipe fixedly connected to the air outlet of the air pump body, an airbag body fixedly connected to the other end of the high-pressure pipe, a pressure sensor fixedly connected to the outer surface of the airbag body, the detection end of the pressure sensor fixedly connected to the inner wall of the airbag body, the telescopic mechanism including a fixed outer shell fixedly connected to the upper surface of the airbag body, a first telescopic rod slidably connected to the inner wall of the fixed outer shell, a second telescopic rod slidably connected to the inner wall of the first telescopic rod, and a guide block fixedly connected to the lower surface of the airbag body.

[0007] Furthermore, the airbag body is composed of an inner airbag layer, a middle airbag layer, and an outer airbag layer. The inner airbag layer is made of nitrile rubber, and the middle airbag layer is fixedly connected to the outer surface of the inner airbag layer. The middle airbag layer is made of para-aramid fiber woven mesh.

[0008] By adopting the above technical solution, the inner layer of the airbag provides the core elasticity of the airbag, ensuring that it can deform with the shape of the gap when it expands, while isolating gas leakage. The middle layer of the airbag resists the radial tension during expansion and prevents the rock edges from puncturing the inner rubber, thus avoiding the airbag from rupturing due to excessive local stress.

[0009] Furthermore, an outer layer of the airbag is fixedly connected to the outer surface of the middle layer of the airbag, and the outer layer of the airbag is made of polyurethane coating.

[0010] By adopting the above technical solution, the gaps in the middle fiber mesh covering the outer layer of the airbag reduce the wear caused by rock particles embedding into the fiber gaps, while improving the smoothness of the airbag surface and reducing the frictional resistance when inserting into the gaps.

[0011] Furthermore, a control panel is fixedly connected to the upper surface of the second telescopic rod. The control panel is electrically connected to the air pump body and the pressure sensor via wires, and the outer surface of the high-pressure pipe is slidably connected to the outer surface of the second telescopic rod.

[0012] Using the above technical solution, the pressure inside the airbag can be easily detected through the control panel.

[0013] Furthermore, a first limiting block is fixedly connected to the side surface of the first telescopic rod, the outer surface of the first limiting block is slidably connected to the inner wall of the fixed housing, and a first fastening bolt is threadedly connected to the outer surface of the fixed housing, with one end of the first fastening bolt fitting against the outer surface of the first telescopic rod.

[0014] By adopting the above technical solution, by rotating the first fastening bolt, one end of the first fastening bolt is in contact with the outer surface of the first telescopic rod, which facilitates the positioning of the first fastening bolt.

[0015] Furthermore, a second limiting block is fixedly connected to the side surface of the second telescopic rod, the outer surface of the second limiting block is slidably connected to the inner wall of the first telescopic rod, and a second fastening bolt is threadedly connected to the outer surface of the first telescopic rod, with the other end of the second fastening bolt abutting against the outer surface of the second telescopic rod.

[0016] By adopting the above technical solution, the outer surface of the second telescopic rod can be easily positioned by rotating the second fastening bolt.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

A guide block 301 is fixedly connected to the lower surface of the airbag body 204.

[0031] Furthermore, the airbag body 204 is composed of an inner airbag layer 205, a middle airbag layer 206, and an outer airbag layer 207. The inner airbag layer 205 is made of nitrile rubber. The middle airbag layer 206 is fixedly connected to the outer surface of the inner airbag layer 205. The middle airbag layer 206 is made of para-aramid fiber woven mesh. The outer airbag layer 207 is fixedly connected to the outer surface of the middle airbag layer 206. The outer airbag layer 207 is made of polyurethane coating.

The control panel 202 is electrically connected to the air pump body 1 and the pressure sensor 201 through wires.

[0032] In this embodiment, the high-pressure pipeline 203 ensures sealed gas transmission, and the pressure sensor 201 monitors the pressure of the inner layer 205 of the airbag in real time and feeds it back to the control panel 202 to avoid overpressure rupture or insufficient pressure.

[0033] Reference Figures 1 to 5 In one aspect of this embodiment, a first limiting block 306 is fixedly connected to the side surface of the first telescopic rod 303, the outer surface of the first limiting block 306 is slidably connected to the inner wall of the fixed housing 308, and a first fastening bolt 302 is threadedly connected to the outer surface of the fixed housing 308, one end of the first fastening bolt 302 is in contact with the outer surface of the first telescopic rod 303.

[0035] In this embodiment, multi-stage adjustment is achieved by fixing the outer shell 308 and using double telescopic rods. With the first fastening bolt 302, the second fastening bolt 305 and the limiting block, the height can be accurately positioned, preventing the telescopic rods from slipping.

It adapts to gaps with dangerous rocks of different heights and improves the airbag's alignment accuracy.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: First, move the entire device to a stable area next to the dangerous rock to be treated, such as a slope platform or temporary support point, ensuring that the air pump body 1 is placed stably to prevent it from tipping over during operation. Pull the first telescopic rod 303 to slide along the inner wall of the fixed outer shell 308 and adjust it to a basic position that matches the height of the gap between the dangerous rocks. Rotate the first fastening bolt 302 so that one end of it fits against the outer surface of the first telescopic rod 303. Initial positioning is completed by the first limiting block 306. Pull the second telescopic rod 304 to slide along the inner wall of the first telescopic rod 303 to further fine-tune the height and horizontal distance, so that the airbag body 204... Align with the gap in the dangerous rock, rotate the second fastening bolt 305 to fit against the outer surface of the second telescopic rod 304, and fix the position using the second limiting block 307. Observe the guide block 301 on the telescopic mechanism 3 to ensure it faces the gap in the dangerous rock, providing precise guidance for subsequent airbag insertion. Confirm that the air pump body 1 is in a de-energized state. Fix one end of the high-pressure pipe 203 of the expansion mechanism 2 to the air outlet of the air pump body 1, and connect the other end to the air inlet of the inner layer 205 of the airbag. Check the sealing condition of the interface. A small amount of sealant can be applied to enhance airtightness and prevent gas leakage during inflation. Start the control. Panel 202 confirms that the signal from the pressure sensor 201's detection end connected to the inner wall of the airbag inner layer 205 is normal, allowing real-time feedback of the airbag's internal pressure. Then, the airbag body 204 is guided by guide block 301 and slowly inserted into the crevice of the dangerous rock, ensuring stable force exertion during airbag inflation and preventing easy detachment. Observe the fit between the outer layer 207 of the airbag and the rock crevice to prevent the airbag surface from being directly scratched by sharp rock edges. Then, by activating the air pump body 1 on control panel 202, the high-pressure gas generated by the air pump is delivered to the inner layer 205 of the airbag via high-pressure pipe 203, and the airbag begins to inflate. Layer 205, with its high elasticity, deforms according to the shape of the crevice, gradually filling the crevice space. The middle layer 206 of the airbag resists the radial tension generated by expansion, while preventing rock edges from piercing the inner layer. Pressure sensor 201 transmits the internal pressure data of the airbag to control panel 202 in real time. When the control panel 202 shows that the pressure has reached the target value, or when it is observed that the dangerous rock has fully separated from the mountain after the crevice has widened, the air pump can be turned off. By activating the pressure relief function of the air pump on control panel 202, the gas inside the airbag is slowly released. After the airbag is fully contracted, the airbag is retracted from the crevice of the dangerous rock through telescopic mechanism 3.
