Description

Technical Field

[0001] This utility model relates to the field of coal mine safety technology, and more specifically, to a ventilation and water pipeline hanging device. Background Technology

[0002] In the process of safe production and tunneling in underground mines, the ventilation and water pipelines are the "lifeline" of underground tunneling, and the quality of their connection directly affects construction efficiency and safety.

[0003] In related technologies, in tunneling operations, a single anchor bolt is typically used to suspend and extend six pipelines: air supply, water supply, grouting, nitrogen injection, and dual drainage. The design load-bearing capacity of a single anchor bolt is usually based on coal mine safety regulations (such as MT / T1061-2008), and its rated pull-out force is generally 50-100kN. However, the total load of the six air and water pipelines (including the weight of the medium inside the pipes) far exceeds the safety threshold of a single anchor bolt. Taking a 4-inch steel pipe as an example, a single 5-meter-long pipe weighs about 25kg, and six pipes together weigh 150kg. Adding the air and water medium inside the pipes (water about 10kg / m, with fluctuating wind load), the total weight can reach over 300kg. Under long-term static loads, coupled with underground vibrations (such as blasting and equipment operation), the anchor bolt threads are prone to fatigue fracture.

[0004] Furthermore, the ventilation and water pipelines in the relevant technology are suspended by a single anchor rod, lacking redundant design. If defects occur in the anchor rod material (such as substandard heat treatment), installation angle deviation (such as the standard requirement that the angle with the roof be ≤15°), or weathering and spalling of the surrounding rock, the lack of backup support points may cause the pipeline to fall instantly, damaging materials, switches and other equipment and facilities, and even causing secondary injuries (such as injuring workers or blocking escape routes), affecting the life and health of workers and the safe production of the mine.

[0005] In conclusion, how to provide a feng shui pipe hanging device to improve the hanging safety of feng shui pipes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] 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 scope of protection of the present utility model.

[0028] The core of this utility model is to provide a hanging device for feng shui pipes, which will be described below in conjunction with... Figures 1-4 The diagrams in the document introduce and explain the various components that make up the model:

[0029] The ventilation and water pipe hanging device includes a first anchor rod 1, a second anchor rod 2 and a hanging rod 3. The first anchor rod 1 is used to fix to the side wall of the tunnel and extends horizontally. The second anchor rod 2 is used to fix to the bottom surface of the tunnel and extends vertically. The hanging rod 3 extends vertically.

[0030] A first sleeve 11 and a second sleeve 12 are fixed on the first anchor rod 1. Both the first sleeve 11 and the second sleeve 12 extend in the vertical direction. The first sleeve 11 is fitted onto the top of the hanging rod 3, and the second sleeve 12 is fitted onto the top of the second anchor rod 2. The hanging rod 3 is provided with a number of hanging components 31 for hanging the feng shui pipe 100.

[0031] Specifically, when the device needs to be installed, the first anchor bolt 1 and the second anchor bolt 2 are first fixed to the side wall and bottom surface of the tunnel, respectively. The installation position of the second anchor bolt 2 should correspond to the position of the second sleeve on the first anchor bolt 1. The second anchor bolt 2 and the second sleeve are fixedly connected, which can be a direct fixed connection or an indirect fixed connection. The hanging rod 3 is fixed on the first sleeve, and the hanging rod 3 is equipped with a hanging component 31. The air and water pipe 100 is hung on the hanging component 31. The gravity or vibration of the air and water pipe 100 is transmitted to the first sleeve through the hanging rod 3, and then to the first anchor bolt 1. The force and vibration borne by the first anchor bolt 1 will be transmitted to the second anchor bolt 2 through the second sleeve simultaneously, thus providing double protection.

[0032] The ventilation and water pipe suspension device provided by this utility model, through the design of a first anchor rod 1 and a second anchor rod 2, with the first anchor rod 1 being the main anchor rod and the second anchor rod 2 being the secondary anchor rod, bears the main load and distributes the weight of the ventilation and water pipe 100 through the suspension rod 3. The second anchor rod 2 is used to bear the load of the first anchor rod 1 when it fails, thereby supporting the suspension rod 3 and buying time for maintenance. At the same time, through the double-sleeve design of the first sleeve 11 and the second sleeve 12, two connection points can be formed on the first anchor rod 1, reducing the failure probability of the first anchor rod 1 using a single connection point. This ventilation and water pipe suspension device can achieve two levels of protection: Level 1 protection: the first anchor rod 1 + double sleeve bears the static load; Level 2 protection: the second anchor rod 2 intervenes in the event of dynamic loads, such as explosive vibration or main anchor rod breakage. Furthermore, the redundant design of the double sleeve significantly improves safety, making it particularly suitable for reliable use in high-vibration environments underground.

[0033] Based on the various embodiments of this application, the first sleeve 11 and the second sleeve 12 are respectively located on the left and right sides of the first anchor rod 1, and the first sleeve 11 and the second sleeve 12 are staggered in the extension direction of the first anchor rod 1; this arrangement can disperse the bearing force of the first anchor rod 1, thereby ensuring the reliability of the first anchor rod 1.

[0034] Based on the various embodiments of this application, the hanging component 31 is a hook, which is welded and fixed to the hanging rod 3. The hook can be a steel bar, which is convenient to connect and has high strength.

[0035] Based on the various embodiments of this application, there are multiple hanging components 31, which are spaced apart along the extension direction of the hanging rod 3; the number of hanging components 31 should not be less than the number of air and water pipes 100 to meet the usage requirements.

[0036] Based on the various embodiments of this application, the hook is provided with anti-slip protrusions and recesses to prevent the air pipe 100 from sliding.

[0037] Based on the various embodiments of this application, the second anchor rod 2, the hanging rod 3, and the hanging component 31 are all metal parts, with high strength and long service life; and / or, the first anchor rod 1 is a left-hand threaded steel resin anchor rod. The first anchor rod 1 can be a full-length anchor rod, such as the MSGLD-500 20 / 1800mm left-hand threaded steel resin anchor rod, which penetrates deep into the stable layer of the surrounding rock of the roadway to provide basic tensile strength and rigid support for pipeline hanging; MSGLD is the product model code of the left-hand threaded steel resin anchor rod, MSG represents "threaded steel", indicating that the rod material is threaded steel, LD refers to "anchor rod", indicating that the product type is anchor rod; 500 indicates that the tensile strength grade of the rod is 500MPa, which belongs to high-strength anchor rod; 20 / 1800mm refers to the rod diameter of 20mm and the length of 1800mm, respectively.

[0038] Based on the various embodiments of this application, a first fastener 4 and a second fastener 5 are also included. The first fastener 4 is installed on the hanging rod 3 and is used to fasten the hanging rod 3 and the first sleeve 11. The second fastener 5 is installed on the second anchor rod 2 and is used to fasten the second anchor rod 2 and the second sleeve 12. The setting of the first fastener 4 and the second fastener 5 can ensure the stability of the hanging rod 3 and the first sleeve 11, as well as the stability of the second anchor rod 2 and the second sleeve 12.

[0039] Based on the various embodiments of this application, the first fastener 4 is located at the top of the first sleeve 11, and the first fastener 4 can be fixedly connected to the hanging rod 3, that is, the hanging rod 3 is hung on the first sleeve 11, and the first fastener 4 can prevent the hanging rod 3 from falling downward; the second fastener 5 is located at the bottom of the second sleeve 12, and the second fastener 5 can be fixedly connected to the second anchor rod 2 to prevent the second sleeve 12 from falling downward along the second anchor rod 2.

[0040] Based on the various embodiments of this application, the first fastener 4 and the second fastener 5 are both threaded fasteners, and the hanging rod 3 and the second anchor rod 2 are both threaded rods. The first fastener 4 is threadedly engaged with the hanging rod 3 and is used to lock the hanging rod 3 to the first sleeve 11. The second fastener 5 is threadedly engaged with the second anchor rod 2 and is used to lock the second anchor rod 2 to the second sleeve 12. Specifically, the threaded fastener can be a nut, which facilitates operation and allows for easy height adjustment of the hanging rod 3 through the engagement of the nut and the threaded rod. Furthermore, both the first fastener 4 and the second fastener 5 are bidirectional adjustable nuts, which are locked to the first anchor rod 1 by the first sleeve 11 and the first fastener 4. The first sleeve 11 is fitted onto the exposed threaded section of the hanging rod 3, and the first fastener 4 is used to suspend and fix the horizontal relative position of the air and water pipe 100 and the first anchor rod 1. The second sleeve 12 is fitted onto the upper end of the second anchor rod 2, and the second fastener 5 is used to support the horizontal relative position of the second sleeve 12 and the first anchor rod 1. The first fastener 4 and the second fastener 5 have both "axial locking" and "radial limiting" functions. That is, the first fastener 4 achieves the purpose of preventing loosening, and the second fastener 5 achieves the purpose of support, avoiding the overall failure caused by the loosening of a single connection point, forming a two-level safety redundancy. Even if the hook fails, the second anchor rod 2 can still temporarily bear the load, buying time for maintenance. At the same time, the double sleeve connection also reduces the probability of single connection point failure of the anchor rod.

[0041] Based on the various embodiments of this application, the position between the first fastener 4 and the hanging rod 3 is adjustable, and the position between the second fastener 5 and the second anchor rod 2 is adjustable. Specifically, the height of the hanging rod 3 should be adjusted according to the position of the air duct 100. After the adjustment is appropriate, the first fastener 4 locks the hanging rod 3 and the first sleeve. The position between the second fastener 5 and the second anchor rod 2 is adjusted according to the height of the second sleeve, so as to better support the second sleeve.

[0042] In one specific embodiment, the ventilation and water pipe suspension device adopts a double suspension structure, using the roadway support anchor rod as the basic load-bearing unit. Through a three-level connection of "anchor-rod-pipe," it achieves orderly suspension of multiple pipes and double safety redundancy. Multiple sets of arc-shaped suspension components 31, such as hooks, are welded onto the suspension rod 3 to adapt to ventilation and water pipes 100 of different diameters. The contact surfaces between the suspension components 31 and the ventilation and water pipes 100 have anti-slip textures to increase friction and prevent the ventilation and water pipes 100 from sliding. Six ventilation and water pipes 100 are suspended by independent hooks. The suspension rod 3 distributes the concentrated load to the anchoring point of the first anchor rod 1, avoiding overload of a single pipe from affecting the overall system. This device can be welded from some scrap anchor rods, has a simple structure, is safe and reliable, easy to operate, and is easy to manufacture and install, saving costs. It can eliminate the safety hazards caused by single anchor rod suspension, ensuring the life and health of workers and safe production in the mine.

[0043] Furthermore, after multiple tests, the design of this feng shui pipeline suspension device is reasonable, with a simple structure that facilitates installation and disassembly. During field use, the tunnels equipped with this new feng shui pipeline suspension device exhibit a higher safety factor. This device utilizes a "redundancy backup" principle, transforming a single load-bearing structure into a composite system. When the first anchor bolt 1 fails due to material defects, overload, or surrounding rock deformation, the second anchor bolt 2 immediately assumes the load, preventing the pipeline from falling and eliminating the possibility of secondary injuries to personnel caused by the instantaneous fall of the feng shui pipeline 100 due to anchor bolt breakage. Data shows that with dual protection, the failure probability of the feng shui pipeline 100 suspension system drops from 0.3% with a single anchor bolt to below 0.01%, effectively protecting the feng shui pipeline 100 equipment, reducing safety hazards during construction, and protecting the personal safety of construction personnel, demonstrating significant value for widespread application.
