Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable trench support. Background Technology

[0002] Cable trenches are underground conduits used for laying and replacing power and telecommunications cables. They also serve as enclosure structures for cable installations. Common types of cable trenches include cable tunnels, above-ground cable trenches, and underground cable trenches.

[0003] Currently, multi-layer cable supports are installed in cable trenches for cable laying. Chinese patent publication CN219892813U discloses a cable trench rolling cable support device, including: a support, several crossbars, several rollers, and several outer protective wheels. The crossbars are horizontally spaced along the vertical direction on the support. The rollers are sleeved on the crossbars and are evenly spaced. The outer protective wheels are vertically installed on both sides of each roller in the horizontal direction and are connected between adjacent crossbars. After installation, the outer protective wheels and rollers form a grid structure, with two adjacent rollers on the top and bottom and two adjacent outer protective wheels on the left and right forming a grid point.

[0004] However, the cable trench rolling cable support device described in this patent document contains a large number of individual components, and both the rolling reel and the outer protective wheel are mounted on the crossbar, making the installation of the cable trench rolling cable support device quite complex. If it is assembled first and then transported to the installation destination, more transportation space and logistics costs are required, and the limited space in the cable trench will also make on-site installation inconvenient. If individual parts are transported to the site and then assembled, a lot of manpower and resources will be required during transportation, and the large number of components will also make installation more manpower and resources-intensive. Moreover, the installation process of the cable trench rolling cable support device is even more inconvenient in the narrow cable trench. Utility Model Content

[0005] Based on the above description, this utility model provides a cable trench bracket, which aims to solve the problem that the existing cable trench brackets are inconvenient to install, transport and maintain due to the large number of individual parts and complicated assembly.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cable trench support, comprising: A frame that provides storage space; A bracket assembly array is disposed within the frame. The bracket assembly array includes multiple bracket assemblies arranged sequentially along the height direction of the frame. The bracket assemblies are detachably connected to the frame. All the bracket assemblies divide the accommodating space into multiple accommodating areas.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the bracket assembly includes a bracket cross plate and rollers, the bracket cross plate being detachably connected to the frame, and the rollers being rotatably disposed on the bracket cross plate.

[0009] Furthermore, the bracket assembly also includes a crossbar and at least one pair of support frames. The crossbar is connected to the bracket cross plate through the at least one pair of support frames. There are multiple rollers, all of which are sleeved on the crossbar and located between each pair of support frames. All of the rollers are spaced apart along the axial direction of the crossbar.

[0010] Furthermore, the bracket assembly also includes a first support rod, the receiving area has a first wall and a second wall opposite to each other, the two ends of the first support rod are connected to the first wall and the second wall respectively, at least one first support rod is provided between each two adjacent rollers, and the first support rod is provided with a through hole for the crossbar to pass through.

[0011] Furthermore, the frame has opposing first and second support plates, the first support plate being fixed to the sidewall of the cable trench, and the bracket assembly further includes at least one pair of second support rods, the two ends of which are connected to the first and second walls respectively. Each pair of support frames is divided into a first support frame and a second support frame. One of the second support rods in each pair is disposed between the first support frame and the first support plate, and the other of the second support rods in each pair is disposed between the second support frame and the second support plate.

[0012] Furthermore, it also includes clamping components, the number of which is equal to the number of rollers, each clamping component corresponding to one of the rollers, the clamping components being arranged opposite to the rollers, and the clamping components cooperating with the rollers to clamp the cable.

[0013] Furthermore, the clamping assembly includes a threaded rod, a threaded sleeve, and a clamping plate. One end of the threaded rod is connected to the first wall, and the other end of the threaded rod is connected to the threaded sleeve. The clamping plate is rotatably connected to the end of the threaded sleeve away from the threaded rod.

[0014] Furthermore, the clamping assembly also includes a guide for guiding the displacement of the clamping plate.

[0015] Furthermore, the guide member includes a sleeve and a guide rod, one end of the guide rod is connected to the clamping plate, and the other end of the guide rod is inserted into the sleeve.

[0016] Furthermore, at least one support foot is provided at the bottom of the frame.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) In this application, the bracket assembly is a modular structure, and the key components are concentrated on the bracket assembly. This reduces the number of components that need to be installed separately when the cable trench support is installed. At the same time, the detachable connection between the bracket assembly and the frame makes it easier to install, transport and maintain the cable trench support.

[0018] (2) By setting rollers, a first support rod and a second support rod in the bracket assembly, the cables are installed in different grid spaces to facilitate heat dissipation and subsequent maintenance and management of the cables. At the same time, laying the cables on the rollers reduces the scratch damage to the cables.

[0019] (3) By setting up a clamping component, this application can clamp the cable in conjunction with the roller, which reduces the movement of the cable after installation. Compared with the existing cable trench support, which uses cable ties, clamps, etc. to fix the cable to the existing cable trench support after laying the cable, the clamping component in this application saves more installation time. Also, because the clamping component is part of the support, the clamping effect is more reliable. Attached Figure Description

[0026] Reference Figures 1 to 3As shown, this utility model provides a technical solution: a cable trench support, including a frame 10 and a bracket assembly array 20. The frame 10 has an accommodating space 11. The bracket assembly array 20 is disposed within the frame 10. The bracket assembly array 20 includes a plurality of bracket assemblies 21 arranged sequentially along the height direction of the frame 10. The bracket assemblies 21 are detachably connected to the frame 10. All the bracket assemblies 21 divide the accommodating space 11 into a plurality of accommodating areas 111.

[0027] For example, the bracket assembly 21 and the frame 10 can be connected by bolts or the like, and by adjusting the height of the bracket assembly 21, the spatial dimensions of the accommodating area 111 can be adapted to the diameter of the cable.

[0028] In this embodiment, the frame 10 is the main body of the cable trench support. The frame 10 has a mounting hole on one side and is fixed to the side wall of the cable trench by expansion screws. In actual use, the cable is laid on the bracket assembly 21. The bracket assembly 21 here is a modular structure, and the key components are concentrated on the bracket assembly 21. In this way, the number of components that need to be installed separately during the installation of the cable trench support is small. At the same time, the bracket assembly 21 and the frame 10 are detachably connected, which makes it easier to install, transport and maintain the cable trench support.

[0029] Reference Figures 1 to 3 As shown, in some embodiments, the bracket assembly 21 includes a bracket cross plate 211 and rollers 212. The bracket cross plate 211 is detachably connected to the frame 10, and the rollers 212 are rotatably disposed on the bracket cross plate 211.

[0030] For example, the roller 212 is preferably H-shaped or the like, and the roller 212 is made of a smooth, wear-resistant insulating material, preferably SMC material.

[0031] In this embodiment, the cable is directly laid on the roller 212. When the cable is laid on the roller 212 and needs to be dragged back and forth, sliding friction is formed between the cable and the roller 212, which greatly reduces the scraping and wear of the cable.

[0032] In some embodiments, one end of the bracket horizontal plate 211 is provided with a protrusion, and the frame 10 is provided with a slot corresponding to the protrusion. The protrusion is inserted into the slot, and the other end of the bracket horizontal plate 211 is connected to the frame 10 by bolts.

[0033] Reference Figures 1 to 3As shown, in some embodiments, the bracket assembly 21 further includes a crossbar 213 and at least one pair of support frames 214. The crossbar 213 is connected to the bracket cross plate 211 through at least one pair of support frames 214. There are multiple rollers 212, all of which are sleeved on the crossbar 213 and located between each pair of support frames 214. All rollers 212 are spaced apart along the axial direction of the crossbar 213.

[0034] In this embodiment, the two ends of the crossbar 213 are fixed to the bracket cross plate 211 by the support frame 214, and the support frame 214 is arranged at both ends of the crossbar 213.

[0035] Reference Figures 1 to 3 As shown, in some embodiments, the bracket assembly 21 further includes a first support rod 215, the receiving area 111 has a first wall 1111 and a second wall 1112 opposite to each other, the two ends of the first support rod 215 are connected to the first wall 1111 and the second wall 1112 respectively, at least one first support rod 215 is provided between each two adjacent rollers 212, and the first support rod 215 is provided with a through hole for the crossbar 213 to pass through.

[0036] For example, the first support rod 215 may be made of a smooth and wear-resistant insulating material. The first wall 1111 is the top wall of the receiving area 111, and the second wall 1112 is the bottom wall of the receiving area 111.

[0037] In this embodiment, the first support rod 215 separates multiple cables, avoiding friction between cables and facilitating subsequent identification, maintenance and management. At the same time, the first support rod 215 also serves to support the crossbar 213.

[0038] It should be noted that, with Figure 1 Taking the perspective of the first support rod 215 in the uppermost accommodating area 111 as an example, from top to bottom, the upper end of the first support rod 215 is connected to the top horizontal plate of the frame 10, and the other end of the first support rod 215 is connected to the bracket horizontal plate 211 opposite to the top horizontal plate of the frame 10. Here, the first support rod 215 serves to support the top horizontal plate of the frame 10. In other accommodating areas 111, the first support rod 215 is set between two adjacent bracket horizontal plates 211. Here, the first support rod 215 serves to support the bracket horizontal plate 211.

[0039] Reference Figures 1 to 3As shown, in some embodiments, the frame 10 has opposing first support plate 12 and second support plate 13. The first support plate 12 is used to fix to the side wall of the cable trench. The bracket assembly 21 also includes at least one pair of second support rods 216. The two ends of the second support rods 216 are connected one-to-one to the first wall 1111 and the second wall 1112. Each pair of support frames 214 is divided into a first support frame 2141 and a second support frame 2142. One of the second support rods 216 in each pair is disposed between the first support frame 2141 and the first support plate 12, and the other of the second support rods 216 in each pair is disposed between the second support frame 2142 and the second support plate 13.

[0040] For example, the second support rod 216 may be made of a smooth and wear-resistant insulating material.

[0041] In this embodiment, the second support rod 216 is provided at both ends of the crossbar 213 to provide support. At the same time, the second support rod 216 can prevent the cable installed at the roller 212 from scraping and abrading the edge of the frame 10 during dragging.

[0042] It should be noted that, with Figure 1 Taking the perspective of the frame as an example, from top to bottom, the upper end of the second support rod 216 in the uppermost accommodating area 111 is connected to the top horizontal plate of the frame 10, and the other end of the second support rod 216 is connected to the bracket horizontal plate 211 opposite to the top horizontal plate of the frame 10. Here, the second support rod 216 serves to support the top horizontal plate of the frame 10. In other accommodating areas 111, the second support rod 216 is set between two adjacent bracket horizontal plates 211. Here, the second support rod 216 serves to support the bracket horizontal plate 211.

[0043] Reference Figure 1 , Figure 4 As shown, in some embodiments, the cable trench support further includes clamping components 30, the number of clamping components 30 being equal to the number of rollers 212, the clamping components 30 and rollers 212 corresponding one-to-one, the clamping components 30 and rollers 212 being arranged opposite to each other, and the clamping components 30 and rollers 212 cooperating to clamp the cable.

[0044] In this embodiment, the clamping assembly 30 is operated to clamp the cable after the cable laying is completed. The clamping assembly 30 is directly set on the cable trench support body and is manufactured together with other parts of the cable trench support. Therefore, it is no longer necessary to use additional parts such as cable ties and clamps to fix the cable to the cable trench support. As a result, the clamping method in this application is more reliable and reduces unnecessary installation procedures.

[0045] Reference Figure 1 , Figure 4As shown, in some embodiments, the clamping assembly 30 includes a threaded rod 31, a threaded sleeve 32, and a clamping plate 33. One end of the threaded rod 31 is connected to the first wall 1111, and the other end of the threaded rod 31 is connected to the threaded sleeve 32. The clamping plate 33 is rotatably connected to the end of the threaded sleeve 32 away from the threaded rod 31.

[0046] For example, the outer surface of the threaded sleeve 32 can be circular or polygonal, preferably regular hexagonal, and the clamping plate 33 is arc-shaped. The rotatable connection between the clamping plate 33 and the threaded sleeve 32 can be a ball joint connection, a bearing connection, or a stepped shaft and stepped hole connection, etc.

[0047] In this embodiment, after the cable is installed, when the threaded sleeve 32 is turned, the clamping plate 33 moves downward to fit the cable, and then the threaded sleeve 32 is tightened with a tool to clamp the cable.

[0048] The axis of the clamping plate 33 coincides with the axis of the threaded sleeve 32. The clamping plate 33 can rotate around this axis. When the clamping plate 33 is in contact with the cable, since the clamping plate 33 and the threaded sleeve 32 are rotatably connected, the clamping plate 33 will not rotate with the rotation of the threaded sleeve 32 when the threaded sleeve 32 is tightened.

[0049] Reference Figure 1 , Figure 4 As shown, in some embodiments, the clamping assembly 30 further includes a guide 34 for guiding the displacement of the clamping piece 33.

[0050] In this embodiment, the guide 34 guides the clamping plate 33 to move toward the cable until the clamping plate 33 completely clamps the cable.

[0051] Reference Figure 1 , Figure 4 As shown, in some embodiments, the guide member 34 includes a sleeve 341 and a guide rod 342, one end of which is connected to the clamping plate 33, and the other end of which is inserted into the sleeve 341.

[0052] In this embodiment, one end of the sleeve 341 is connected to the first wall 1111, and the relative movement of the guide rod 342 and the sleeve 341 guides the movement of the clamping plate 33.

[0053] Reference Figure 1 As shown, in some embodiments, at least one support foot 40 is provided at the bottom of the frame 10.

[0054] In this embodiment, the first support plate 12 in the frame 10 is fixed to the side wall of the cable trench by expansion bolts. Then, the bottom of the frame 10 is added with support feet 40 to cooperate with the first support plate 12 so that the cable trench bracket can be installed stably. At the same time, due to the influence of the installation environment, the cable trench bracket needs to be far away from the ground. At this time, the support feet 40 can also prevent the bottom of the cable trench bracket from being completely suspended and unstable.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
