Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element preceded by "comprises... a" does not, without more limitations, foreclose the existence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0025] As Figure 1 shown, one fire pipe laying combined bridge of the present application includes five core components, namely, a main frame 1, a buckle mechanism 2, a reinforcing member 3, a positioning support 4, and a telescopic rod 5. These five components work together to provide the required support stability and safety for fire pipe laying.
[0026] The bridge includes a main frame 1 as the overall load-bearing base. The main frame 1 is the main support part of the entire structure, used to install the remaining components and bear all external loads. The main frame 1 can be made of steel material or high-strength aluminum alloy, and is designed as a rectangular frame structure to increase rigidity and flatness. For example, the main frame 1 can be formed into a stable closed loop by welding in place, and is fixed to the installation plane by bolts.
[0027] The buckle mechanism 2 is arranged on the main body frame 1, which is mainly used for fixing the fire pipe and preventing loosening. Specifically, the buckle mechanism 2 is designed with a double-layer elastic arm structure 21, and the double-layer elastic arms are connected to different parts of the main body frame 1 and can be close to each other to wrap the fire pipe to increase the clamping force. The double-layer elastic arms can be processed by using elastic metal materials to realize the clamping effect by bending the opposite arc surfaces. In addition, a non-slip pad layer 22 is covered on the inner side surface of the elastic arm facing the fire pipe. The pad layer is usually made of flexible materials with a certain friction coefficient, such as rubber products, which can effectively reduce the change of the position of the fire pipe caused by external disturbances such as vibration. At the same time, in order to ensure the long-term reliability and prevent slipping, the buckle mechanism 2 is internally designed with a tooth-shaped structure 23. These teeth can be meshed into the small groove area of the rubber non-slip pad, further improving the locking force during actual installation.
[0028] The reinforcing member 3 is connected to the main body frame 1 to enhance the structural strength and stability of the bridge. The reinforcing member 3 can be achieved by bending steel plates or other high-tensile-strength metal sheets into angular shapes and evenly distributing multiple rivets or studs at the four corner positions of the main body frame 1, thereby forming a triangular support-like strengthening mode to avoid deformation of the frame under external pressure.
[0029] The positioning support 4 is also arranged at a specific pre-set point on the surface of the main body frame 1, which is used to accurately guide the fire pipe path and preliminarily realize the constraint in position. The support is generally a set of L-shaped leg combined units, each short arm end is provided with a round hole for matching and installing with the corresponding threaded hole pre-configured on the main body frame 1. In the construction scene, by adjusting the relative distance between different positioning supports 4, the requirements of various pipe diameter specifications can be accurately adapted.
[0030] The telescopic rod 5 is located in the internal cavity area of the main body frame 1 and is finally connected to the node below the buckle mechanism 2 to transmit support power and weaken environmental vibration interference. The device contains several sections of circular steel pipes that can be extended or shortened in length, and spring 9 elements are provided between each adjacent steel pipe to maintain a certain tension value to buffer the vibration force. At the same time, by precisely controlling the effective height value of the telescopic rod 5 through the cooperation of the precision gear set and the rotating handle, the entire buckle mechanism 2 obtains additional auxiliary support performance in a constant horizontal state.
[0031] To solve the technical problem of how to enhance the locking reliability, the bridge adopts a comprehensive solution. First, the double-layer elastic arm structure 21 in the buckle mechanism 2 improves the pressure range of direct contact with the pipe wall; second, the non-slip pad material layer is introduced as an isolation measure to greatly reduce the risk of dynamic movement; finally, the tooth-shaped structure 23 design is matched with mechanical interlocking, so that the clamping jaw will not be unlocked and deviated even after aging.
[0032] As Figure 1 shown in the drawings, in one embodiment, the main frame 1 of the fire pipe layout combined bridge of the application is provided with anti-seismic supports 6 on both sides of the top end. The anti-seismic supports 6 are installed on the top edge area of the main frame 1 and are fixed with the main frame 1 by bolt connection or welding. The anti-seismic supports 6 include upper and lower parts: the upper part is a rigid connecting piece to realize fixation with the wall or other building structure, and the lower part uses an elastic material layer to disperse the vibration load transmitted from the outside and prevent local stress concentration. The overall design aims to improve the anti-interference ability of the entire combined bridge structure in a vibrating environment.
[0033] For example, the anti-seismic supports 6 can be constructed by fixing a perforated connecting piece to the top of the main frame 1, and then cooperating with a rubber or polyurethane buffer layer to ensure the balance of connection strength and vibration attenuation performance. When reinforcing, the anti-seismic supports 6 can be installed on the wall by pre-buried bolts or adhesive fixation, thereby achieving the technical implementation of the overall anti-seismic effect.
[0034] As Figure 1 shown in the drawings, in one embodiment, the main frame 1 of the fire pipe layout combined bridge of the application is provided with anti-seismic supports 6 on both sides of the top end. The anti-seismic supports 6 are installed on the top edge area of the main frame 1 and are fixed with the main frame 1 by bolt connection or welding. The anti-seismic supports 6 include upper and lower parts: the upper part is a rigid connecting piece to realize fixation with the wall or other building structure, and the lower part uses an elastic material layer to disperse the vibration load transmitted from the outside and prevent local stress concentration. The overall design aims to improve the anti-interference ability of the entire combined bridge structure in a vibrating environment.
[0035] Specifically, it can be achieved by the following steps: a continuous or segmented transverse reinforcing rib 7 is made of steel and embedded or fixed to the specified area of the main frame 1, for example, by positioning the groove combined with the spot welding process to ensure firm connection and prevent loosening. To further optimize the performance, the transverse reinforcing rib 7 can be provided with several hollow units or curved parts to balance the weight distribution, and the reserved installation space in the main frame 1 is completed for final assembly. For example, in actual production, the transverse reinforcing rib 7 can be assembled by robot automatic welding, thereby ensuring consistency and stability.
[0036] In one embodiment, the double-layer elastic arm structure 21 of the buckle mechanism 2 of the fire pipe layout combined bridge of the present application is composed of two layers of elastic materials. The outer layer of the structure is responsible for providing good external contact and protection properties, while the inner layer of elastic material adopts a higher hardness design to improve the restoring force, so that the double-layer elastic arm can clamp the target more firmly when fixing the fire pipe. This design combines the different mechanical properties of the two materials, aiming to balance durability and clamping effect. Through reasonable layered structure design, the double-layer elastic arm can adapt to fire pipes of different diameters and ensure stability in a vibrating environment. At the same time, it is positioned on the corresponding mounting area of the main frame 1, and cooperates with the non-slip pad 22 and the tooth-shaped structure 23 to complete the pipe locking function.
[0037] Specifically, for example, the double-layer elastic arm structure 21 can be manufactured by injection molding process. Specifically, the inner layer material with high strength and high restoring force characteristics is embedded as the core of the outer layer substrate, and the two layers of materials are tightly combined to form an integrated assembly using chemical bonding or hot pressing technology. The assembly is then integrated into the buckle mechanism 2 and fixed in the designated assembly slot of the main frame 1, thereby optimizing the pipe constraint capability of the bridge without affecting the overall layout.
[0038] As shown in Figure 2 In one embodiment, the non-slip pad 22 of the fire pipe layout combined bridge of the present application is provided on the contact surface inside the buckle mechanism 2, and its composition structure includes a textured surface structure and an energy-absorbing foam layer 8. The textured surface structure is designed in the form of small protrusions or grooves, which can generate greater frictional resistance between the buckle mechanism 2 and the fire pipe, effectively reducing the micro-displacement caused by external vibration. The energy-absorbing foam layer 8 is embedded at the bottom of the non-slip pad 22, which has good energy absorption capacity and can weaken the vibration acting on the fire pipe in the form of deformation.
[0039] Specifically, the overall shape design of the non-slip pad 22 matches the inner contour of the buckle mechanism 2, ensuring close fitting and providing continuous protection. In addition, the energy-absorbing foam layer 8 is directly adhered or pressed inside the double-layer elastic arm structure 21 of the buckle mechanism 2, while absorbing external energy through material properties.
[0040] For example, the energy-absorbing foam layer 8 can be made of foam material with certain rebound characteristics, and the textured surface structure is formed by mold pressing, and then firmly fixed in the specified area inside the double-layer elastic arm structure 21. This combination not only simplifies the installation process, but also meets the requirements of shock absorption and fixation in actual working conditions.
[0041] As shown in Figure 3As shown, in one embodiment, a tooth-shaped structure 23 with adjustable inclination angle is adopted in the buckle mechanism 2 of the fire pipe layout combined bridge of the present application. The main function of this structure is to adapt to the outer wall of fire pipes with different roughness to improve the clamping performance under various surface conditions. The tooth-shaped structure 23 is installed at the end position of the double-layer elastic arm structure 21 in the buckle mechanism 2, and its overall design is a kind of occlusion component directly contacting the fire pipe. Through special structural design, this tooth-shaped structure 23 can dynamically adjust its angle range according to the characteristics of the outer wall, thereby ensuring higher clamping reliability.
[0042] For example, by introducing a hinged movable joint connection form, the tooth-shaped structure 23 can freely deflect within a preset angle range. This joint connection is fixed to one end of the double-layer elastic arm structure 21, and a reset force is provided by the built-in spring 9 to ensure stable angle response. At the same time, the presence of the reinforcing member 3 enhances the overall support capability of the main frame 1 to the entire buckle mechanism 2, so that the tooth-shaped structure 23 can still effectively transmit force to the fire pipe and maintain the locking firmness even in the case of external environmental changes. Under this structural design, the position and form of the tooth-shaped structure 23 are less affected by external working conditions, thus having wider use adaptability.
[0043] In one embodiment, the reinforcing member 3 of the fire pipe layout combined bridge of the present application is fixedly connected with the main frame 1 by welding. The main function of the reinforcing member 3 is to improve the rigidity and stability of the entire bridge structure in a vibrating environment, and it forms an integrated force bearing system by being firmly connected with the main frame 1. In order to ensure that the two can be fully combined and effectively suppress vibration transmission, the welding process is selected to firmly attach the reinforcing member 3 to the key stress points of the main frame 1. This position is usually the part near the support point of the main frame 1 or the main area bearing the fire pipe.
[0044] Specifically, the reinforcing member 3 can be designed into a specific shape to enhance the overall structural strength, and then uniformly welded after being attached to the main frame 1. For example, the reinforcing member 3 is made into a U-shaped or L-shaped plate structure, so that its edge part tightly contacts the surface of the main frame 1, and continuous operation is performed along the combined edge during welding. In this way, the load distribution characteristics at the connection point can be significantly improved, and the vibration problem caused by external excitation can be reduced. Further, the pre-positioning by the clamp before welding can ensure accurate installation of the two.
[0045] As Figure 4As shown, in one embodiment, the positioning bracket 4 of the fire pipe layout combined bridge of the present application is equipped with an arc-shaped guide groove 11, which is designed to assist the rapid positioning of the fire pipe. The arc-shaped guide groove 11 is located on the side of the positioning bracket 4 facing the installation side of the fire pipe, and its curvature and width are matched with the outer diameter of the fire pipe to ensure that the fire pipe can be accurately embedded and preliminarily limited. Through this structure, the fire pipe can naturally slide along the arc-shaped guide groove 11 to the predetermined position, avoiding the problem of direction deviation that may occur during assembly. At the same time, the shape of the arc-shaped guide groove 11 matches the shape of the fire pipe, so it can effectively disperse the force during assembly, thereby reducing the potential interference caused by stress concentration on the fire pipe and the entire bridge structure.
[0046] For example, the positioning bracket 4 is formed by bending a metal plate, and an arc-shaped guide groove 11 is provided on the side facing the fire pipe. The groove is defined by two parallel arc surfaces, leaving a space between them that is adapted to the size of the fire pipe. The specific structure of the arc-shaped guide groove 11 can further include a layer of anti-slip material to optimize the contact performance. Specifically, the positioning bracket 4 is fixed to the main frame 1 and cooperates with the buckle mechanism 2, so that the fire pipe can be accurately transferred to the buckle mechanism 2 for final fixation after being introduced from the arc-shaped guide groove 11. This connection method not only simplifies the installation steps, but also ensures the accuracy and reliability of the overall layout.
[0047] As shown, Figure 4 In one embodiment, the positioning bracket 4 of the fire pipe layout combined bridge of the present application includes a special structural design. To reduce friction and facilitate traction during pipe docking, an innovative structure is used in this part. Specifically, a plurality of small-sized balls 12 are arranged in a regular manner inside the positioning bracket 4. These balls 12 are arranged along the circumference to provide a smooth rolling support surface. This design takes advantage of the rolling properties of the balls 12 to replace the traditional fixed contact form, thereby significantly reducing the frictional resistance between the pipe and the contact surface of the bracket. Through this structure, a more flexible operation experience can be achieved and the loss during construction can be reduced.
[0048] For example, the positioning bracket 4 is installed on the main frame 1 near the part where the fire pipe enters or passes through. To achieve the above features, the balls 12 are fixed by a built-in annular track and are kept on the inner cavity wall of the positioning bracket 4 by precise assembly. These balls 12 are made of wear-resistant materials and are fixed in the track groove by press fitting, allowing them to rotate freely within the track limits but not to fall out, forming a stable and effective low-friction interface.
[0049] As shown, Figure 3As shown, in one embodiment, the telescopic rod 5 of the fire pipe laying combined bridge of the present application comprises a built-in spring 9 device and a limiting device, which work together to realize the automatic adjustment of the clamping of the fire pipe. The telescopic rod 5 is installed between the main frame 1 and the buckle mechanism 2, and a spring 9 in a compressed state is arranged inside the telescopic rod 5. One end of the spring 9 is connected to the fixed part of the telescopic rod 5, and the other end is connected to the movable part of the telescopic rod 5. At the same time, in order to ensure that the telescopic rod 5 can be relatively fixed in the initial state, a positioning bolt 10 is installed on the fixed part, and a positioning hole 13 is arranged on the corresponding side wall of the movable part, and the limiting is completed by embedding the positioning bolt 10 into the positioning hole 13. In actual use, the compression state of the spring 9 maintains a fixed elastic preload, thereby ensuring the stability of the entire structure in the initial state.
[0050] Further, when the pipe needs to be fixed after butt joint, the positioning bolt 10 is loosened and separated from the positioning hole 13. This operation releases the limiting constraint of the movable part of the telescopic rod 5, and at this time the spring 9 in the compressed state releases the stored energy and pushes the movable part of the telescopic rod 5 to move. The movable part drives the buckle mechanism 2 to approach the fire pipe until the elastic arm structure tightly wraps around the fire pipe. Specifically, the release process of the spring 9 provides accurate and continuous force to the buckle mechanism 2, avoiding the loosening problem that may exist in the traditional mechanical fastening mode. For example, by designing matched spring 9 stiffness and stroke range, it can adapt to pipes of different diameters and automatically complete clamping without additional adjustment steps.
[0051] In actual operation, when the device is used, the fire pipe can be placed into the main frame 1, and the positioning support 4 is used to preliminarily limit and guide the position of the fire pipe. Then, the buckle mechanism 2 clamps the fire pipe firmly, and the double-layer elastic arm structure 21 can increase the clamping force on the pipe, the anti-slip pad layer 22 can effectively reduce the displacement of the pipe caused by vibration, and the tooth-shaped structure 23 can prevent loosening during use. At the same time, the telescopic rod 5 can alleviate external vibration and provide stable support force for the buckle mechanism 2, ensuring the reliability of clamping. In addition, the reinforcing member 3 is connected with the main frame 1, further enhancing the rigidity and stability of the overall bridge structure, thereby ensuring the safe layout of the fire pipe.
[0052] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the embodiments of the present disclosure, and it should be understood that the above description is only a specific embodiment of the present disclosure and is not used to limit the protection scope of the present disclosure.
