Description

Technical Field

[0001] The present invention relates to the technical field of cable equipment, and more particularly to a cable bracket that is convenient for disassembly and maintenance and an installation method thereof. Background Art

[0002] At present, cable brackets in cable trenches generally include columns and several support frames arranged vertically. The support frames are generally directly fixed to the columns by welding. During construction, expansion bolts are used to fix the columns in the cable trench. The material is generally selected from steel or other composite materials.

[0003] In the related art, since the components of the cable bracket are welded together, once it is manufactured and delivered, parameters such as the length and spacing of the support frames of the cable bracket cannot be adjusted. In addition, during the cable laying stage, the components of the welded cable bracket have been welded. When laying the lower-layer cables, the upper support frames will cause interference, which increases the construction difficulty to a certain extent. During the cable maintenance stage, when a local cable bracket is damaged, operations such as cutting and welding are required to replace it, and the risk coefficient of hot work in the cable trench is relatively high. Summary of the Invention

[0004] In view of the above problems, the present application provides a cable bracket that is convenient for disassembly and maintenance and an installation method thereof. The cable bracket can realize the rapid installation and disassembly of the cantilever bracket. During construction, the length and installation spacing of the cantilever bracket can be adjusted as needed, and it can be installed in layers. When laying the lower-layer cables, only the corresponding cable bracket components are installed, increasing the working space during the cable laying construction period. During operation and maintenance, the damaged cantilever bracket can also be replaced individually, without the need for hot work in the cable trench, reducing the operation risk coefficient.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

A second limiting plate is arranged on the second locking tongue. The second limiting plate is pressed against the baffle on the right side under the action of the fourth elastic member.

[0015] Further, the mounting bracket includes a rear vertical plate. A first longitudinal guide post is provided on the first locking tongue, and the suspended end of the first longitudinal guide post passes through a first avoidance hole on the rear vertical plate and extends to the rear side of the rear vertical plate. The first elastic member is a first spring sleeved on the first longitudinal guide post. A second longitudinal guide post is provided on the second locking tongue, and the suspended end of the second longitudinal guide post passes through a second avoidance hole on the rear vertical plate and extends to the rear side of the rear vertical plate. The third elastic member is a third spring sleeved on the second longitudinal guide post.

[0016] Further, a transverse guide post is provided on the inner end face of the second locking tongue, and a guide hole matching the transverse guide post is provided on the inner end face of the first locking tongue.

The distance that the first locking tongue extends into the first lateral insertion port is less than the radius of the first rounded corner. The distance that the second locking tongue extends into the second lateral insertion port is less than the radius of the second rounded corner.

[0020] Further, end protrusions corresponding to the end insertion ports one by one are provided on the outer side surface of the web, first lateral protrusions corresponding to the first lateral insertion ports one by one are provided on the outer side surface of the first wing plate, and second lateral protrusions corresponding to the second lateral insertion ports one by one are provided on the outer side surface of the second wing plate.

In this way, first, when installing the cable bracket, select the cantilever bracket with corresponding parameters for assembly according to different design requirements, so as to achieve flexible matching of multiple sizes under the specified modulus and meet the requirements of various sizes of cable trenches. Second, the components of this cable bracket can be installed in layers. When laying cables in the lower part, only the corresponding cantilever bracket needs to be installed, effectively increasing the net space during cable laying construction and reducing the construction difficulty. Third, during operation and maintenance, the damaged cantilever bracket can be quickly replaced individually, without the need for hot work in the cable trench, reducing the operation risk coefficient.

[0054] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below in conjunction with the accompanying drawings in the embodiments of this application. The described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0055] For the convenience of description, a coordinate system is defined for the cable bracket as Figure 1 shown, with the left-right direction as the transverse direction, the front-back direction as the longitudinal direction, and the up-down direction as the vertical direction.

[0056] Embodiment 1

[0057] As Figure 1 , Figure 3 and Figure 4 shown, a cable bracket that is convenient for disassembly and maintenance includes a column 1 and a cantilever bracket 2 fixedly arranged on the column 1 in a detachable manner, and the cantilever bracket 2 is vertically arranged with respect to the column 1.

[0058] As Figure 8 , Figure 9 andFigure 10 As shown, the column 1 includes a web 11. At the left and right ends of the web 11, there are respectively provided wing plates perpendicular to the web 11 and extending forward. The web 11 and the wing plates together form a U-shaped structure with an opening facing forward. For the convenience of description, the wing plate on the left side is defined as the first wing plate 12, and the wing plate on the right side is defined as the second wing plate 13. A plurality of end insertion ports 111 are uniformly arranged on the web 11 in the vertical direction. On the first wing plate 12, there is provided a first side insertion port 121 corresponding to each of the end insertion ports 111 one by one; on the second wing plate 13, there is provided a second side insertion port 131 corresponding to each of the end insertion ports 111 one by one.

[0059] The cantilever support frame includes a cantilever beam. An installation cavity with a closed front end is arranged inside the cantilever beam. And on the end face (i.e., the front face) of the cantilever beam close to the column 1, there is provided an end insertion block 2211 that cooperates with the end insertion ports 111. Inside the installation cavity, there are provided a first locking tongue 23 that cooperates with the first side insertion port 121 and a second locking tongue 24 that cooperates with the second side insertion port 131. Both the first locking tongue 23 and the second locking tongue 24 can slide back and forth and left and right relative to the cantilever beam.

[0060] Between the first locking tongue 23 and the cantilever beam, there is provided a first elastic member, and the first elastic member is used to prevent the first locking tongue 23 from moving away from the column 1. Between the first locking tongue 23 and the cantilever beam or the second locking tongue 24, there is provided a second elastic member. On the left side wall of the installation cavity, there is provided a first sliding groove 211 for accommodating the end of the first locking tongue 23. The first locking tongue 23 can slide back and forth in the first sliding groove 211, and under the elastic pressing action of the second elastic member, the end of the first locking tongue 23 extends outside the cantilever beam through the first sliding groove 211.

[0061] Between the second locking tongue 24 and the cantilever beam, there is provided a third elastic member, and the third elastic member is used to prevent the second locking tongue 24 from moving away from the column 1. Between the second locking tongue 24 and the cantilever beam or the first locking tongue 23, there is provided a fourth elastic member. On the right side wall of the installation cavity, there is provided a second sliding groove 212 for accommodating the end of the second locking tongue 24. The second locking tongue 24 can slide back and forth in the second sliding groove 212, and under the elastic pressing action of the fourth elastic member, the end of the second locking tongue 24 extends outside the cantilever beam through the second sliding groove 212.

[0062] The upper side and the outer end face of the first locking tongue 23 are smoothly transitioned. Exemplarily, the upper side and the outer end face of the first locking tongue 23 are smoothly transitioned by means of a first rounded corner, and the radius of the first rounded corner is equal to the thickness of the first locking tongue 23 (i.e., the dimension in the vertical direction).

[0063] The lower side and the outer end face of the second locking tongue 24 are smoothly transitioned. Exemplarily, the lower side and the outer end face of the second locking tongue 24 are smoothly transitioned by means of a second rounded corner, and the radius of the second rounded corner is equal to the thickness of the second locking tongue 24 (i.e., the dimension in the vertical direction).

[0064] Exemplarily, the first locking tongue 23 and the second locking tongue 24 have equal thicknesses.

[0065] Further, as Figure 11 and Figure 12 shown, the cantilever beam includes a main beam body 21 in a tubular structure with both ends open, and a mounting bracket 22 is fixedly arranged in the main beam body 21 in a detachable manner. As Figure 13 and Figure 14 shown, the mounting bracket 22 includes a front vertical plate 221 for blocking the front opening of the main beam body 21. Horizontal plates 222 perpendicular to the front vertical plate 221 and extending away from the column 1 are respectively arranged at the upper and lower ends of the front vertical plate 221, and the horizontal plates 222 are located inside the main beam body 21. An end plug-in block 2211 is fixedly arranged on the side of the front vertical plate 221 facing the column 1. The first locking tongue 23 and the second locking tongue 24 are located between the two horizontal plates 222. The main beam body 21 and the mounting bracket 22 together form the mounting cavity with a closed front end.

[0066] Exemplarily, as a specific implementation manner, the main beam body 21 in this embodiment is made of a rectangular steel pipe.

[0067] Further, the first locking tongue 23, the second locking tongue 24, the first elastic member, the second elastic member, the third elastic member, and the fourth elastic member are all arranged on the mounting bracket 22. The first chute 211 is arranged on the left side wall of the main beam body 21, and the second chute 212 is arranged on the right side wall of the main beam body 21.

[0068] The reason for such a design is that by setting the mounting bracket 22 and arranging the first locking tongue 23 and the second locking tongue 24 on the mounting bracket 22, the first locking tongue 23, the second locking tongue 24, the first elastic member, the second elastic member, the third elastic member and the fourth elastic member can be connected into a whole through the mounting bracket 22 and used as a complete clamping component, and then the clamping component can be installed into the main beam body 21. In this way, the processing of the cantilever bracket 2 can be effectively facilitated, and once a certain part is damaged, it is not necessary to scrap the whole, and only the damaged part needs to be replaced.

[0069] Further, baffles 223 are respectively arranged at both ends of the cross plate 222, and the baffles 223 are fixedly connected to the cross plate 222 in a detachable belt manner. Exemplarily, the baffles 223 are fixedly connected to the cross plate 222 of the belt by screws. A first limiting plate 231 is arranged on the first locking tongue 23, and the first limiting plate 231 is pressed against the baffle 223 on the left side under the action of the third elastic member; a second limiting plate 241 is arranged on the second locking tongue 24, and the second limiting plate 241 is pressed against the baffle 223 on the right side under the action of the fourth elastic member.

[0070] The reason for such a design is that by setting the baffles 223, the limit positions for the first locking tongue 23 and the second locking tongue 24 to eject outwards can be restricted. In this way, when installing the whole clamping component, it is not necessary to manually hold the first locking tongue 23 and the second locking tongue 24, so that the clamping component can truly form a whole with stable structure.

[0071] As a specific implementation manner, in this embodiment, the second elastic member and the fourth elastic member are arranged between the first locking tongue 23 and the second locking tongue 24. As Figure 15 shown, a transverse guide post 242 extending inwards perpendicular to the second locking tongue 24 is arranged on the inner end face (taking the side where the first locking tongue 23 and the second locking tongue 24 face each other as the inner side) of the second locking tongue 24, a guide hole 232 cooperating with the transverse guide post 242 is arranged on the inner end face (taking the side where the first locking tongue 23 and the second locking tongue 24 face each other as the inner side) of the first locking tongue 23, the transverse guide post 242 can slide in the guide hole 232, and the relative sliding between the first locking tongue 23 and the second locking tongue 24 is realized through the cooperation of the two. The second elastic member and the fourth elastic member are telescopic springs 255 sleeved on the transverse guide post 242, and both ends of the telescopic spring 255 respectively abut against the inner end faces of the first locking tongue 23 and the second locking tongue 24. Exemplarily, two transverse guide posts 242 are arranged on the second locking tongue 24.

[0072] As a specific implementation manner, as Figure 6 andFigure 14 As shown, in this embodiment, the mounting bracket 22 includes a rear vertical plate 224, and the upper and lower ends of the rear vertical plate 224 are respectively fixedly connected to the rear end of the horizontal plate 222. On the side of the first locking tongue 23 away from the column 1, a first longitudinal guide post 233 extending outward perpendicular to the first locking tongue 23 is provided, and the free end of the first longitudinal guide post 233 passes through the rear vertical plate 224 and extends to the rear side of the rear vertical plate 224. A first avoidance hole 2241 for accommodating the first longitudinal guide post 233 is provided on the rear vertical plate 224. The first avoidance hole 2241 is an oblong hole, and the first longitudinal guide post 233 can move left and right within the first avoidance hole 2241. The first elastic member is a first spring 251 sleeved on the first longitudinal guide post 233. One end of the first spring 251 abuts against the first locking tongue 23, and the other end of the first spring 251 abuts against the rear vertical plate 224. On the side of the second locking tongue 24 away from the column 1, a second longitudinal guide post 243 extending outward perpendicular to the second locking tongue 24 is provided, and the free end of the second longitudinal guide post 243 passes through the rear vertical plate 224 and extends to the rear side of the rear vertical plate 224. A second avoidance hole 2242 for accommodating the second longitudinal guide post 243 is provided on the rear vertical plate 224. The second avoidance hole 2242 is an oblong hole, and the second longitudinal guide post 243 can move left and right within the second avoidance hole 2242. The third elastic member is a third spring 253 sleeved on the second longitudinal guide post 243. One end of the third spring 253 abuts against the second locking tongue 24, and the other end of the third spring 253 abuts against the rear vertical plate 224.

[0073] As a specific implementation manner, as Figure 7 shown, in this embodiment, the mounting bracket 22 is fixedly connected to the main beam body 21 through a bolt assembly. The bolt assembly includes a fixing bolt 261 penetrating the main beam body 21 in the vertical direction. A fixing nut 262 is provided below the main beam body 21 on the fixing bolt 261. A through hole for accommodating the fixing bolt 261 is provided on the horizontal plate 222 of the mounting bracket 22, that is, the fixing bolt 261 penetrates the mounting bracket 22 in the vertical direction. Exemplarily, two groups of bolt assemblies are provided between the mounting bracket 22 and the main beam body 21.

[0074] As Figure 2 and Figure 6As shown, a limit bolt 31 is provided on the side of the cantilever bracket 2 away from the column 1 between the cantilever bracket 2 and the column 1. The limit bolt 31 runs horizontally through the column 1. First mounting holes 141 for receiving the limit bolt 31 are provided on both the first wing plate 12 and the second wing plate 13 of the column 1. A second mounting hole 213 for receiving the limit bolt 31 is provided on the main beam body 21, that is, the limit bolt 31 runs horizontally through the cantilever beam. A locking nut 32 is provided on the limit bolt 31, and the column 1 is clamped between the locking nut 32 and the head of the limit bolt 31. Exemplarily, the locking nut 32 is a wing nut.

[0075] Further, as Figure 8 shown, stiffening plates 14 corresponding to the end insertion interfaces 111 one by one are provided on both the first wing plate 12 and the second wing plate 13, and the lower side surface of each stiffening plate 14 is an inclined surface. First mounting holes 141 for receiving the limit bolt 31 are provided on each stiffening plate 14.

[0076] In this way, it can not only play a role in supporting the cantilever bracket 2, enhancing the structural strength between the cantilevers and the column 1, but also reduce the material used for the column 1 and lower the cost.

[0077] An installation method of a cable bracket convenient for disassembly and maintenance includes the following steps:

[0078] First, as Figure 16 shown, the column 1 is fixed to the side wall of the cable trench by means of embedding or driving expansion bolts.

[0079] Second, select a cantilever bracket 2 with a suitable length and the installation position of the cantilever bracket 2 according to needs.

[0080] Third, as Figure 17 and 18 shown, the cantilever bracket 2 is in a vertical state, and the end insertion block 2211 at the front end of the cantilever bracket 2 abuts against the web 11 of the column 1.

[0081] Fourth, as Figure 19As shown, rotate the cantilever bracket 2 clockwise. When the first locking tongue 23 contacts one side surface of the first wing plate 12 and the second locking tongue 24 contacts the inner side surface of the second wing plate 13, since there is a smooth transition between the upper side surface and the outer end surface of the first locking tongue 23 and there is a smooth transition between the lower side surface and the outer end surface of the second locking tongue 24, therefore, the first locking tongue 23 and the second locking tongue 24 will not be jammed between the first wing plate 12 and the second wing plate 13, but will retract inward under the action of the first wing plate 12 and the second wing plate 13. At this time, the telescopic spring 255 is compressed. Until when the cantilever bracket 2 is in a horizontal state, at this time the first locking tongue 23 is aligned with the first lateral insertion port 121 on the first wing plate 12, the second locking tongue 24 is aligned with the second lateral insertion port 131 on the second wing plate 13, and under the action of the telescopic spring 255, the first locking tongue 23 will extend into the first lateral insertion port 121, and the second locking tongue 24 will be inserted into the second lateral insertion port 131, that is, as Figure 20 shown in the state.

[0082] Fifth, push the cantilever bracket 2 forward as a whole. The cantilever bracket 2 will move forward, so that the end plug block 2211 at the front end of the cantilever bracket 2 is inserted into the end insertion port 111 on the web 11 of the column 1. At the same time, under the restrictive action of the first lateral insertion port 121 and the second lateral insertion port 131, the first locking tongue 23 and the second locking tongue 24 will not move relative to the column 1 together with the cantilever bracket 2, and the first spring 251 and the third spring 253 are compressed.

[0083] Sixth, when the first mounting hole 141 of the column 1 is aligned with the second mounting hole 213 on the cantilever beam, insert the limit bolt 31 and tighten the lock nut 32. Thus, the installation process of the cantilever bracket 2 is completed.

[0084] Further, as Figure 8 and Figure 9 shown, a first positioning plate 15 is provided above each of the first lateral insertion ports 121 on the first wing plate 12, and the distance from the first positioning plate 15 to the upper side surface of the corresponding first lateral insertion port 121 is equal to the distance between the upper side surface of the first locking tongue 23 and the upper side surface of the cantilever beam. A second positioning plate 16 is provided below each of the second lateral insertion ports 131 on the second wing plate 13, and the distance from the second positioning plate 16 to the lower side surface of the corresponding second lateral insertion port 131 is equal to the distance between the lower side surface of the second locking tongue 24 and the lower side surface of the cantilever beam.

[0085] The reason for such a design is that by setting the first positioning plate 15 and the second positioning plate 16, after the cantilever bracket 2 is installed, the front end of the cantilever bracket 2 is positioned by the end insertion block 2211, and both sides are positioned by the first positioning plate 15, the first locking tongue 23, the second positioning plate 16 and the second locking tongue 24, and is supported and positioned by the limit bolt 31 slightly further back, so the connection structure is reliable.

[0086] Furthermore, the distance between the side of the first positioning plate 15 and the second positioning plate 16 away from the web 11 to the web 11 is less than the protruding length of the end insertion block 2211, and as Figure 5 shown, the distance B that the first locking tongue 23 extends into the first lateral insertion port 121 is less than the radius of the first rounded corner, and the distance C that the second locking tongue 24 extends into the second lateral insertion port 131 is less than the radius of the second rounded corner.

[0087] The reason for such a design is that when disassembling the cantilever bracket 2, first, the limit bolt 31 needs to be disassembled. At this time, the cantilever bracket 2 will move backward (i.e., away from the column 1 side) under the elastic restoring force of the first spring 251 and the third spring 253 until the front side of the first locking tongue 23 abuts against the front side of the first chute 211, and the front side of the second locking tongue 24 abuts against the front side of the second chute 212, and at this time, the end insertion block 2211 disengages from the end insertion port 111. Then, rotate the cantilever bracket 2 counterclockwise. Since the distance B that the first locking tongue 23 extends into the first lateral insertion port 121 is less than the radius of the first rounded corner, and the distance C that the second locking tongue 24 extends into the second lateral insertion port 131 is less than the radius of the second rounded corner, therefore, the first rounded corner and the second rounded corner can play a guiding role, enabling the cantilever bracket 2 to turn past the dead point and achieve counterclockwise rotation. At the same time, as Figure 20 shown, since the distance between the side of the first positioning plate 15 and the second positioning plate 16 away from the web 11 to the web 11 is less than the protruding length of the end insertion block 2211, when the end insertion block 2211 abuts against the web 11, there will be a gap A between the first positioning plate 15, the second positioning plate 16 and the front end face of the cantilever beam, and the first positioning plate 15 and the second positioning plate 16 will not limit the rotation of the cantilever bracket 2. When the first locking tongue 23 disengages from the first lateral insertion port 121 and the second locking tongue 24 disengages from the second lateral insertion port 131, the disassembly of the cantilever bracket 2 is completed. Through the above analysis, it can be seen that in order to achieve the disassembly of the cantilever bracket 2 by rotation, the above two design requirements are essential.

[0088] Furthermore, as Figure 8 and Figure 10As shown, on the outer side surface of the web 11, there are end protrusions 112 corresponding one-to-one to the end insertion openings 111. On the outer side surface of the first wing plate 12, there are first lateral protrusions 122 corresponding one-to-one to the first lateral insertion openings 121. On the outer side surface of the second wing plate 13, there are second lateral protrusions 132 corresponding one-to-one to the second lateral insertion openings.

[0089] In this way, on the one hand, without increasing the overall thickness of the column 1, the depths of the end insertion opening 111, the first lateral insertion opening 121, and the second lateral insertion opening 131 can be deepened. On the other hand, due to the design of the end protrusions 112, the first lateral protrusions 122, and the second lateral protrusions 132, when the column 1 is embedded into the side wall of the cable trench, the structural strength of the connection between the column 1 and the cable trench can be increased.

[0090] Embodiment 2

[0091] As Figure 21 shown, the mounting bracket 22 further includes a vertical plate 225 located between the first locking tongue 23 and the second locking tongue 24, and the upper and lower ends of the vertical plate 225 are fixedly connected to the horizontal plate 222 by welding. On the inner end surface of the first locking tongue 23, there is a first positioning post 234, and the second elastic member is a second spring 252 sleeved on the first positioning post 234. One end of the second spring 252 abuts against the inner end surface of the first locking tongue 23, and the other end of the second spring 252 abuts against the vertical plate 225.

[0092] On the inner end surface of the second locking tongue 24, there is a second positioning post 244, and the fourth elastic member is a fourth spring 254 sleeved on the second positioning post 244. One end of the fourth spring 254 abuts against the inner end surface of the second locking tongue 24, and the other end of the fourth spring 254 abuts against the vertical plate 225.

[0093] Since the second spring 252 and the fourth spring 254 abut against the vertical plate 225, when the first locking tongue 23 and the second locking tongue 24 move back and forth, the second spring 252 and the fourth spring 254 will also move back and forth relative to the vertical plate 225.

[0094] The remaining structures are the same as those in Embodiment 1.

[0096] Remove the rear vertical plate 224 described above. The first elastic member is a first tension spring disposed between the first locking tongue 23 and the front vertical plate 221.

One end of the second tension spring is connected to the second locking tongue 24, and the other end of the second tension spring is connected to the front vertical plate 221.
