Description

Technical Field

[0001] This utility model relates to the technical field of cable laying, and in particular to a self-fixing support for cable tunnels. Background Technology

[0002] A cable tunnel is a corridor or tunnel-like structure used to accommodate a large number of cables laid on cable supports. In addition to providing better protection for the cables, cable tunnels also facilitate inspection and maintenance by maintenance personnel.

[0003] Cable tunnels are equipped with fixed supports for securing cables. These supports not only provide support and protection for the cables in the tunnel, but also allow for the classification and labeling of cable lines, facilitating routine inspections and repairs by maintenance personnel. A well-designed cable support system can also improve the efficiency of cable routing and reduce the risk of mutual interference and damage between cables.

[0004] Existing technologies typically use pre-embedded fixing plates, expansion bolts, or chemical anchors to fix the supports. While this method is simple, it increases the overall project cost and places higher demands on the tunnel construction team. This is because pre-embedded fixing plates can easily result in uneven installation surfaces for the supports, increasing the difficulty of installation. Furthermore, using expansion bolts or chemical anchors can easily damage the reinforcing steel bars in the tunnel's concrete, potentially harming the overall tunnel structure. Utility Model Content

[0005] To facilitate the installation of fixed supports for cable placement within cable tunnels, this application provides a self-fixing support for cable tunnels.

[0006] This application provides a self-fixing support for cable tunnels, which adopts the following technical solution:

[0007] A self-fixing support for cable tunnels includes multiple support frames and support rods for connecting adjacent support frames, wherein the multiple support frames are arranged along the length of the tunnel.

[0008] The support frame includes four fixed seats that fit against the inner wall of the tunnel. The number of support rods is the same as the number of fixed seats. The two ends of the support rods are fixed to the corresponding fixed seats. A support tube is provided between two fixed seats in the vertical direction. The support tube is provided with a fixing bracket for fixing cables. A connecting rod is provided between two fixed seats in the horizontal direction and away from the ground. The fixed seats are provided with support assemblies for fixing the support rods, fixing assemblies for fixing the support tubes, and connecting assemblies for fixing the connecting rods.

[0009] By adopting the above technical solution and setting the support rod, the distance between two adjacent support frames can be determined while fixing the two adjacent support frames. The support frame is composed of a fixed seat, a support tube, and a connecting rod. In the actual assembly process, the distance between the support tube and the connecting rod and the fixed seat can be adjusted so that the fixed seat is pressed against the inner wall of the tunnel, thereby making the support frame firmly installed in the tunnel without affecting the structure of the tunnel itself, which facilitates the installation and placement of cables.

[0010] Preferably, the support assembly includes support screws fixed at both ends of the support rod, and the fixed base has a through hole for the support screws to pass through. The outer diameters of the support screws and the through hole are both smaller than the outer diameter of the support rod, and a support nut is threaded onto the support screw.

[0011] By adopting the above technical solution, the support screw and the support nut cooperate to connect the support tie rod to two adjacent support frames, which facilitates the installation of the two adjacent support frames. Furthermore, by setting the support tie rod, the distance between the two adjacent support frames can be determined while fixing them.

[0012] Preferably, the fixing assembly includes fixing bolts and adjusting screws respectively disposed at both ends of the support tube. Both ends of the support tube are provided with support plates. Both the support plates and the fixing seats are provided with through holes for fixing nuts or adjusting screws to pass through. The support plate at one end of the support tube is connected to the corresponding fixing seat by fixing bolts. Fixing nuts are threaded onto the fixing bolts. The support plate at the other end of the support tube is connected to the corresponding fixing seat by adjusting screws. Four adjusting nuts are threaded onto the adjusting screws. Two adjusting nuts form a group. A single group of adjusting nuts is used to fix the position of the support plate or fixing seat on the adjusting screw.

[0013] By adopting the above technical solution, the screw head of the fixing bolt and the fixing nut cooperate to clamp the support plate and the fixing seat, so that the support tube and the fixing seat are fixed. In actual application, the adjusting nut can be adjusted to adjust the position of the support plate and the fixing seat fixed on the adjusting screw, thereby adjusting the distance between the fixing seats at both ends of the support tube, so that the fixing seat is pressed against the inner wall of the tunnel, improving the reliability and stability of the support frame fixed in the tunnel.

[0014] Preferably, the connecting assembly includes connecting screws fixed at both ends of the connecting rod, a connecting through hole for the connecting screws to pass through on the fixing seat, and two connecting nuts for fixing the fixing seat threaded onto the connecting screws.

[0015] By adopting the above technical solution, the two connecting nuts cooperate to fix the fixing seat on the connecting screw, thereby completing the assembly of the support frame and facilitating the assembly of the support frame.

[0016] Preferably, the fixed bracket is slidably mounted on the support tube, and the end of the fixed bracket is provided with a fixed plate. The fixed plate is provided with a clamping plate and a clamping bolt. A support cavity for accommodating the support tube is provided between the fixed plate and the clamping plate. Both the clamping plate and the fixed plate are provided with clamping through holes for the clamping bolt to pass through. A clamping nut is threaded onto the clamping bolt.

[0017] By adopting the above technical solution, the clamping bolt and clamping nut cooperate to fix the fixed bracket on the support pipe with the cooperation of the fixed plate and the clamping plate. By setting the fixed bracket to slide on the support pipe, the distance between two adjacent fixed brackets can be adjusted according to the actual shape and diameter of the cable, thereby improving the space utilization rate.

[0018] Preferably, the fixed bracket is provided with a plurality of cable clamps, the cable clamps are arranged along the length direction of the fixed bracket, the fixed bracket is provided with clamp bolts for fixing the cable clamps, both the cable clamps and the fixed bracket are provided with clamp through holes for the clamp bolts to pass through, and clamp nuts are threadedly connected to the clamp bolts.

[0019] By adopting the above technical solution, the clamp bolts and clamp nuts cooperate to fix the cable clamp on the fixed bracket, which facilitates the installation of the cable clamp.

[0020] Preferably, both the connecting through hole and the clamping through hole are waist-shaped.

[0021] By adopting the above technical solution, the waist-shaped through hole of the clamp allows for slight adjustment of the position of the cable clamp, which reduces the pressure on the cable from cable clamps located in the same straight line, thereby reducing the external damage to the cable; the waist-shaped connecting through hole allows for adjustment of the position between the two fixing seats in the horizontal direction according to actual needs, thereby improving the strength of the support frame fixed in the tunnel and improving the reliability of the support frame in providing support to the cable.

[0022] Preferably, the fixing bracket is arranged in a trapezoidal shape, and the size of the fixing bracket decreases sequentially along the direction away from the support tube.

[0023] By adopting the above technical solution, it is possible to reduce the amount of material used while ensuring the support strength of the fixed bracket, thereby reducing costs.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up support rods, the distance between two adjacent support frames can be determined while fixing the two adjacent support frames. The support frame consists of a fixed seat, support tube, and connecting rod. In the actual assembly process, the distance between the support tube and the connecting rod and the fixed seat can be adjusted to make the fixed seat press against the inner wall of the tunnel, so that the support frame can be firmly installed in the tunnel without affecting the structure of the tunnel itself, which facilitates the installation and placement of cables.

[0026] 2. The adjusting nut can be adjusted to adjust the position of the support plate and the fixed seat on the adjusting screw, thereby adjusting the distance between the fixed seats at both ends of the support tube, so that the fixed seat is pressed tightly against the inner wall of the tunnel, improving the reliability and stability of the support frame fixed in the tunnel.

[0032] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0033] This application discloses a self-fixing bracket for cable tunnels, as shown in the embodiments below. Figure 1 and Figure 2It includes multiple support frames 1 and support rods 2 for connecting two adjacent support frames 1. The multiple support frames 1 are arranged along the length of the tunnel 4, and the number of support frames 1 depends on the actual length of the tunnel 4. Each support frame 1 includes four fixing seats 11 that fit against the inner wall of the tunnel 4. The number of support rods 2 is the same as the number of fixing seats 11. Each support rod 2 is used to connect the corresponding fixing seats 11 in two adjacent support frames 1. By setting the support rods 2, the distance between two adjacent support frames 1 can be determined while fixing two adjacent support frames 1.

[0034] Reference Figure 2 and Figure 3 The fixed base 11 is provided with a support assembly for fixing the support rod 2. The support assembly includes a support screw 21 fixed at both ends of the support rod 2. The fixed base 11 is provided with a support through hole for the support screw 21 to pass through, so that the outer diameter of the support screw 21 and the support through hole are both smaller than the outer diameter of the support rod 2. The support screw 21 is threaded with a support nut 22. The support nut 22 cooperates with the support rod 2 to fix the fixed base 11 located at both ends of the support rod 2, so that the two adjacent support frames 1 are fixed, which improves the reliability of limiting the distance between the two adjacent support frames 1 by the support rod 2.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A support tube 12 is provided between two fixed seats 11 in the vertical direction. The fixed seat 11 is provided with a fixing component for fixing the support tube 12. The fixing component includes a fixing bolt 13 and an adjusting screw 14 respectively set at both ends of the support tube 12. A support plate 121 is welded and fixed at both ends of the support tube 12. The support plate 121 and the fixed seat 11 are respectively provided with fixing through holes for fixing nuts or adjusting screws 14 to pass through. The support plate 121 at one end of the support tube 12 is fixed to the corresponding fixed seat 11 by fixing bolt 13. A fixing nut is threaded on the fixing bolt 13. The screw head of the fixing bolt 13 cooperates with the fixing nut to clamp the support plate 121 and the fixed seat 11, so that the support tube 12 and the fixed seat 11 are fixed.

[0036] Reference Figure 3The support plate 121 at the other end of the support tube 12 is connected to the corresponding fixed seat 11 by an adjusting screw 14. Four adjusting nuts 141 are threaded onto the adjusting screw 14. Two adjusting screws 14 form a group. A single group of adjusting nuts 141 is used to fix the position of the support plate 121 or the fixed seat 11 on the adjusting screw 14. In actual application, the adjusting nuts 141 can be adjusted to adjust the position of the support plate 121 and the fixed seat 11 fixed on the adjusting screw 14, thereby adjusting the distance between the fixed seats 11 at both ends of the support tube 12, so that the fixed seat 11 is pressed against the inner wall of the tunnel 4, improving the reliability and stability of the support frame 1 fixed in the tunnel 4.

[0037] Reference Figure 2 and Figure 3 A connecting rod 15 is provided between two fixed seats 11 located horizontally and away from the ground. The fixed seat 11 is provided with a connecting assembly for fixing the connecting rod 15. The connecting assembly includes connecting screws 151 fixed at both ends of the connecting rod 15. A connecting through hole is provided on the fixed seat 11 for the connecting screws 151 to pass through. Two connecting nuts 152 are threaded on the connecting screws 151. The two connecting nuts 152 cooperate to fix the fixed seat 11 on the connecting screws 151, thereby completing the assembly of the support frame 1.

[0038] Reference Figure 1 and Figure 4 The support tube 12 is provided with a fixing bracket 3 for fixing the cable. The fixing bracket 3 is slidably mounted on the support tube 12. A fixing plate 31 is welded to the end of the fixing bracket 3. A clamping plate 32 and a clamping bolt 33 are provided on the fixing plate 31. A support cavity for accommodating the support tube 12 is provided between the clamping plate 32 and the fixing plate 31. The support tube 12 fits against the inner wall of the support cavity, so that both the support plate 121 and the positioning plate are provided with clamping through holes for the clamping bolt 33 to pass through. A clamping nut 331 is threaded onto the clamping bolt 33. The clamping bolt 33 and the clamping nut 331 cooperate to fix the fixing bracket 3 on the support tube 12 with the cooperation of the fixing plate 31 and the clamping plate 32. By setting the fixing bracket 3 to slide on the support tube 12, the distance between two adjacent fixing brackets 3 can be adjusted according to the actual shape and diameter of the cable, thereby improving the utilization rate of space.

[0039] Reference Figure 4The fixed bracket 3 is provided with multiple cable clamps 34. The style of the cable clamps 34 can be selected according to actual needs. The cable clamps 34 are arranged along the length of the fixed bracket 3. The fixed bracket 3 is provided with clamp bolts 35 for fixing the cable clamps 34. Both the cable clamps 34 and the fixed bracket 3 are provided with clamp through holes 351 for the clamp bolts 35 to pass through. The clamp bolts 35 are threaded with clamp nuts. The clamp bolts 35 and clamp nuts cooperate to fix the cable clamps 34 on the fixed bracket 3, which facilitates the installation of the cable clamps 34.

[0040] Reference Figure 4 Both the connecting through hole and the clamp through hole 351 are waist-shaped. The waist-shaped clamp through hole 351 allows for slight adjustment of the position of the cable clamp 34, which reduces the pressure on the cable from the cable clamps 34 that are located in the same straight line, thereby reducing the external damage to the cable. The waist-shaped connecting through hole can adjust the position between the two fixing seats 11 located in the horizontal direction according to actual needs, thereby improving the strength of the support frame 1 fixed in the tunnel 4 and improving the reliability of the support frame 1 in providing support to the cable.

[0041] Reference Figure 1 and Figure 4 The fixed bracket 3 is arranged in a trapezoidal shape, and the size of the fixed bracket 3 decreases sequentially in the direction away from the support tube 12. This allows for the reduction of material usage while ensuring the support strength of the fixed bracket 3, thereby reducing costs.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
