Description

Technical Field

[0001] The present application relates to the technical field of cable brackets, and in particular to a simple assembled cable bracket. Background Art

[0002] With the development of urban construction in my country, the demand for electricity in various regions has become more prominent. Many cities are building power infrastructure, and more and more power transmission line projects have been generated. However, due to the limited and expensive land prices in cities, power transmission in urban areas has shifted from the original overhead lines to underground power tunnels. The use of power tunnels for power transmission has become a development trend. At the same time, in order to maintain the city's image, many cities have relocated overhead cables through power tunnels. Arched or ring-shaped cable racks are often used in power tunnels to support cables, so that the cables are arranged neatly and easy to manage and maintain.

[0003] The cable support structure currently used in power tunnels is similar to the materials retrieved by the following applicants: "CN217159206U A power tunnel top pipe section with an assembled cable support", "CN113328397A A cable support structure for a power tunnel pipe and its installation method". Multiple cross bars for fixing cables are installed on the inner side of the support body (arch frame part) through bolt assemblies. However, since the cross bars on both sides extend in a relative shape, a large amount of space inside the power tunnel is occupied, and space for walking and maintenance needs to be reserved in the middle of the power tunnel. This results in the inner diameter of the power tunnel being generally larger and the construction difficulty being higher. In order to reasonably improve this problem, the present application proposes a simple assembled cable support. Summary of the invention

[0004] The purpose of the present application is to solve the technical problem that in the prior art, multiple cross bars for fixing cables are installed on the inner side of the bracket body by bolt assemblies, but since the cross bars on both sides extend in a relative manner, a large amount of space inside the power tunnel is occupied, and space for walking and maintenance needs to be reserved in the middle of the power tunnel, which leads to a generally large inner diameter of the power tunnel and a high construction difficulty. The present application provides a simple assembled cable bracket.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A simple assembled cable bracket, comprising: There are two arc-shaped frames, and the ends of the arc-shaped frames are connected to each other.

[0009] Furthermore, an annular groove is provided on the columnar block, and the end of the compression spring is connected to the annular groove.

[0010] Furthermore, the positioning assembly includes a straight ratchet bar constructed at the bottom of the hinged plate, and the arc blocks are hinged with connecting rods on opposite sides. The two ends of the connecting rods are connected with abutment blocks, which overlap with the straight ratchet bar.

[0011] Furthermore, the stop block is hinged on the connecting rod and connected to the connecting rod via a torsion spring. A limiting mechanism is provided on the connecting rod, and the rotation range of the stop block can be limited by the limiting mechanism.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0019] like Figure 1-Figure 7 As shown, a simple assembled cable bracket proposed in one embodiment of the present application includes: There are two arc frames 1, and the ends are connected to each other. The two arc frames 1 are symmetrical to each other and are arched after being connected. The arc frame 1 includes an arc block 101. An arc plate 102 is constructed on the outer side of the arc of the arc block 101. The arc plate 102 and the inner wall of the cable tunnel are fixed to each other by a bolt assembly. An arc groove 103 is constructed on the inner side of the arc of the arc block 101. A plurality of plate bodies 2 are hinged in the arc groove 103. The plurality of plate bodies 2 are distributed in an interval shape and are hinged in the arc groove 103 one by one along the length direction of the arc groove 103. It should be specifically explained here that the width of the plate body 2 is smaller than the width of the arc groove 103, and the arc groove 103 can accommodate the plate body 2; A fixing assembly 3 is provided on the plate body 2, and the cable can be fixed to the plate body 2 through the fixing assembly 3, so that a plurality of cables can be fixed along the length direction of the plate body 2; The positioning assembly 4 is arranged on the arc block 101. The plate body 2 can be fixed by the positioning assembly 4. After the cable is fixed, the plate body 2 is driven to flip upward along the hinge point and fixed by the positioning assembly 4. After the arc frame 1 is fixed to the inner wall of the tunnel, multiple cables can be fixed on the plate body 2 along the length direction of the plate body 2 through the fixing component 3, and then the plate body 2 is driven to flip upward from top to bottom in sequence, and the multiple plate bodies 2 are fixed one by one through the positioning component 4 during the flipping process. At this time, the multiple plate bodies 2 are all inclined, and the ends of the multiple plate bodies 2 are close to the inner side of the arc block 101. The distance between adjacent plate bodies 2 becomes smaller. On the one hand, the overall occupied space of the bracket can be effectively reduced. On the other hand, the space occupied by the plate body 2 is close to the arc frame 1, which is an area that is not easily accessible to personnel or equipment. The middle area of ​​the relative cable tunnel is vacated, and the passage space for personnel or equipment becomes larger; The present application adopts a coordinated design of the plate body 2, the fixing component 3 and the positioning component 4, so that the plate body 2 can be flipped and fixed after the cable is fixed. Compared with the prior art, the plate body 2 of the present application is inclined, and the spacing between adjacent plate bodies 2 becomes smaller. On the one hand, the overall occupied space of the bracket can be effectively reduced. On the other hand, the space occupied by the plate body 2 is close to the arc frame 1, which is an area that is difficult for personnel or equipment to access. The middle area of ​​the relative cable tunnel is vacated, and the passage space for personnel or equipment becomes larger, so that the inner diameter of the power tunnel can be reduced without affecting the arrangement of cables and the passage of personnel or equipment, thereby reducing the difficulty of cable tunnel construction.

[0020] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, in some embodiments, the fixing assembly 3 includes a hinge plate 301 hinged to the bottom of the plate body 2, the hinge axis of the hinge plate 301 is close to the hinge axis of the plate body 2, a plurality of first card slots 302 are spaced apart at the bottom of the plate body 2, a plurality of second card slots 303 are provided at the top of the hinge plate 301, the first card slots 302 and the second card slots 303 are both arc-shaped, and the end of the hinge plate 301 is fixed to the plate body 2 by a fixing member 304. With this design, when fixing the cable, the cable can be first inserted into the first card slot 302. The hinged plate 301 is then rotated to contact the cable through the second slot 303 thereon to form a clamping fixation, and then the hinged plate 301 and the plate body 2 can be fixed by the fixing member 304, so that the cable cannot be separated from the first slot 302 and the second slot 303 after being fixed. When the cable is damaged and needs to be repaired, the fixing member 304 on the hinged plate 301 and the plate body 2 can be released to allow the cable to be separated from the first slot 302 and the second slot 303.

[0021] like Figure 4 and Figure 6 As shown, in some embodiments, a flexible pad 5 is installed on the inner side of the first card slot 302 and the second card slot 303. The flexible pad 5 is a rubber pad. The flexible pad 5 can protect the cable so that it is not easy to be worn by the first card slot 302 and the second card slot 303 during the installation process.

[0022] like Figure 6 and Figure 7As shown, in some embodiments, the fixing member 304 includes a fixing block 3041 configured at the end of the plate body 2, and a receiving groove 3042 for receiving the fixing block 3041 is provided on the hinge plate 301. When the hinge plate 301 rotates to be parallel to the plate body 2, the fixing block 3041 can be received by the receiving groove 3042. The receiving groove 3042 has a through hole 3043 on the inner wall relative to the plate body 2. A pressing block 3044 is slidably provided in the through hole 3043. The pressing block 3044 is pressed against the plate body 2. The end of the cylindrical block 3046 can extend out of the through hole 3043, and the opposite sides of the fixed block 3041 are provided with a cylindrical groove 3045, and the cylindrical groove 3045 is slidably matched with a cylindrical block 3046. The end of the cylindrical block 3046 is connected to the cylindrical groove 3045 by a compression spring 3047. The compression spring 3047 is used to provide a thrust for forcing the cylindrical block 3046 to extend out of the cylindrical groove 3045. The end of the cylindrical block 3046 contacts and overlaps with the pressing block 3044, and the end of the cylindrical block 3046 can be inserted into the through hole 3043. The two cylindrical blocks 3046 are pushed toward each other so that the accommodating groove 3042 can completely accommodate the fixing block 3041. Then, the two cylindrical blocks 3046 are moved away from each other under the action of the compression spring 3047 and respectively contact the opposite sides of the two pressing blocks 3044. Then, the two cylindrical blocks 3046 can be respectively inserted into the two through holes 3043 and push the two pressing blocks 3044. 044 is extended out of the through hole 3043, so that the hinge plate 301 and the plate body 2 can be fixed, and by pressing the two pressing blocks 3044, the two column blocks 3046 can be driven to approach each other, so as to release the fixation of the hinge plate 301 and the plate body 2. It should be specifically explained that the end of the column block 3046 is constructed with a guiding arc surface 12, which is convenient for the column block 3046 to enter the receiving groove 3042 and to be inserted into the through hole 3043.

[0023] like Figure 6 and Figure 7 As shown, in some embodiments, an annular groove 6 is provided on the columnar block 3046, and the annular groove 6 is provided on opposite sides of the two columnar blocks 3046. The end of the compression spring 3047 is connected to the annular groove 6. When the two columnar blocks 3046 are close to each other, the compression spring 3047 can be accommodated by the annular groove 6, thereby further reducing the volume of the device, thereby reducing the occupied space of the device.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the positioning assembly 4 includes a straight ratchet bar 401 constructed at the bottom of the hinge plate 301, the straight ratchet bar 401 extends along the length direction of the hinge plate 301, and the arc blocks 101 are hinged with connecting rods 402 on the opposite sides, and the hinge axis of the connecting rods 402 is located above the hinge axis of the plate body 2. The ends of the two connecting rods 402 are connected with a stop block 403, and the stop block 403 is in contact with the straight ratchet bar 401. When the plate body 2 is flipped and tilted, the connecting rod 402 can be rotated to make the stop block 403 contacts with the straight ratchet bar 401, and then the plate body 2 can be flipped downward along the hinge point under the action of the cable and its own gravity. At this time, the ratchet bar is pressed on the stop block 403, and the stop block 403 conflicts with the straight ratchet bar 401 to prevent the plate body 2 from rotating, so that the plate body 2 can be fixed. When it is necessary to release the fixation of the plate body 2, the plate body 2 can be flipped upward to separate the stop block 403 from the straight ratchet bar 401, and then the connecting rod 402 can be reset to allow the plate body 2 to flip downward.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the stop block 403 is hinged on the connecting rod 402 and connected to the connecting rod 402 through a torsion spring 7. The movable end of the torsion spring 7 is connected to the stop block 403, and the fixed end thereof is connected to the connecting rod 402. A limiting mechanism 8 is provided on the connecting rod 402, and the limiting mechanism 8 can limit the rotation range of the stop block 403. With such a design, when the plate body 2 is flipped upward, the straight ratchet bar 401 makes an arc motion along the hinge axis of the plate body 2. At this time, the stop block 403 can be flipped slightly with the straight ratchet bar 401, so that the stop block 403 that is in close contact with the straight ratchet bar 401 can be quickly separated from the straight ratchet bar 401, thereby reducing the rotation range of the plate body 2 and reducing the wear on the cable. After the stop block 403 is flipped, it can be reset by the torsion spring 7.

[0026] like Figure 4 and Figure 5 As shown, in some embodiments, the limiting mechanism 8 includes a tripod 801 constructed on two connecting rods 402, and the two tripods 801 are connected to each other through a connecting plate 802, so that the structural strength and stability of the two connecting rods 402 can be improved, and the top of the connecting plate 802 is in contact with and overlapped with the bottom of the stop block 403. When the plate body 2 flips downward under the action of gravity, the stop block 403 is in contact with the straight ratchet bar 401. The stop block 403 is mounted on the connecting plate 802, and a clamping block 803 is constructed on the rotating shaft of the stop block 403. The clamping block 803 and the stop block 403 are respectively located on both sides of the connecting plate 802, and the clamping block 803 is in contact with and overlapped with the connecting plate 802. When the stop block 403 flips with the straight ratchet bar 401, the clamping block 803 can move toward the connecting plate 802 and abut against the connecting plate 802, so as to limit the rotation range of the stop block 403.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, a plurality of flexible blocks 9 are distributed in an arc shape on the back side of the arc block 101. The flexible blocks 9 are rubber blocks fixedly mounted on the arc block 101. The number of the flexible blocks 9 is consistent with the number of the connecting rods 402. The flexible blocks 9 are all constructed with inclined surfaces 10, which are located at the top of the flexible blocks 9, and the width of the flexible blocks 9 gradually decreases from bottom to top. The plurality of inclined surfaces 10 are respectively in contact with and overlapped with the plurality of connecting rods 402. When the block 403 is separated from the straight ratchet bar 401, the connecting rod 402 can be flipped downward under the action of gravity. At this time, the connecting rod 402 can contact the flexible block 9 and slide on the inclined surface 10. At this time, the connecting rod 402 can stop sliding under the action of the flexible block 9, so that the connecting rod 402 is not easy to collide with the lower plate 2.

[0028] like Figure 2 As shown, in some embodiments, a plurality of limit plates 11 are spaced apart in the arc groove 103, and the top of the limit plate 11 is in contact with the bottom of the plate body 2 and overlaps with the bottom of the plate body 2. When the limit plate 11 is in contact with the bottom of the plate body 2, the plate body 2 is horizontal. Such a design facilitates fixing of the cable.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
