Technical Field

[0001] The present application relates to the field of cable arrangement, and in particular to a cable tray that facilitates wiring. Background Art

[0002] Cable trays are commonly used supporting and protecting devices for laying cables in power supply systems of electrical equipment. They protect and guide the cables laid in the cable trays.

[0003] In the related technology, such as publication number CN111952906A, a hot-dip galvanized double-layer cable tray, a cable duct, a layered structure, a locking structure and a fixing structure. The layered structure separates the cable duct into two layers, and a type of cable is laid in each layer, thereby realizing the layered and classified placement of the cables.

[0004] With regard to the above-mentioned related technologies, there is a defect that when laying cables, the lower layer needs to be laid first, and then the upper layer can be laid, which leads to a relatively low wiring efficiency of the cable tray. Summary of the invention

[0005] In order to improve the wiring efficiency of the cable tray, the present application provides a cable tray that is easy to wire.

[0006] The present application provides a cable tray that is convenient for wiring and adopts the following technical solution: A cable tray for facilitating wiring, comprising: Central pivot; A partition plate connected to the peripheral side of the central support shaft, wherein a plurality of the partition plates are evenly distributed in a circle around the center of the central support shaft; The cover plate is connected to one end of the partition plate away from the central support shaft, and the cover plate is located between two adjacent partition plates to form a wiring cavity.

[0007] By adopting the above technical solution, since multiple partition plates are evenly distributed in a circle around the center of the central support axis, there will be no interference in the line of sight between the wiring cavities, so wiring operations can be carried out in different wiring cavities at the same time, thereby improving the wiring efficiency of the cable tray.

[0008] Preferably, a connecting ring is sleeved on the circumferential side of the central support shaft, and a clamping shaft block is connected to the circumferential side of the connecting ring. A plurality of the clamping shaft blocks are evenly distributed around the connecting ring in a circumference. The clamping shaft block is thinner at one end close to the connecting ring, and thicker at one end away from the connecting ring, so as to form a clamping shaft groove between two adjacent clamping shaft blocks; a connecting shaft is provided at one end of the partition plate close to the central support shaft, and the connecting shaft is clamped and inserted into the clamping shaft groove, and at least one clamping shaft groove is spaced between the connecting shafts of two adjacent partition plates.

[0009] By adopting the above technical solution, with the help of the cooperation between the clamping shaft groove and the connecting shaft, a detachable connection between the partition plate and the central support shaft is achieved. Therefore, according to actual use requirements, different numbers of partition plates are spliced ​​together to make cable trays with different numbers of wiring cavities.

[0010] Preferably, the cover plate is in the shape of a bendable thin plate, and the connecting shaft is arranged in the clamping shaft through groove to damp rotation.

[0011] By adopting the above technical solution, when wiring has been completed in one of the wiring cavities and wiring work is being carried out on other wiring cavities, the partition plate corresponding to the wiring cavity where the wiring is completed can be rotated. In this process, the cover plate will bend to reduce the volume of the wiring cavity, so the volume of the wiring cavity being wired can be temporarily increased, thereby increasing the wiring field of view and improving wiring efficiency.

[0012] Preferably, a clamping block, a clamping movable block and an intermediate block are provided between the cover plate and the partition plate, the clamping block is fixedly connected to one end of the partition plate away from the central support shaft; the clamping movable block is bolted to a side of the clamping block away from the partition plate; the intermediate block is provided on the cover plate, and the intermediate block is clamped by the clamping block and the clamping movable block.

[0013] By adopting the above technical solution, while realizing the detachable connection between the cover plate and the partition plate, the assembly and disassembly between the cover plate and the partition plate can be realized from the circumferential direction, so it is also convenient to open the cover plate later to carry out cable maintenance work.

[0014] Preferably, one of the clamping fixed blocks is provided in combination with two of the clamping movable blocks, a clamping plate slot is formed between one of the clamping movable blocks and one of the clamping fixed blocks, and the clamping plate slot is a T-shaped slot structure; the middle block is made of elastic material, and the middle block is inserted into the clamping plate slot.

[0015] By adopting the above technical solution, since the cover plate is in a certain bending state when connected to the two adjacent partition plates, the clamping plate through groove is set, and the clamping block and the clamping movable block can be connected first before the cover plate is connected to the partition plate. When the cover plate is subsequently installed, it is only necessary to slide the middle block from the ports at both ends of the clamping plate groove. Therefore, in the process of fixing the clamping block and the clamping movable block, there is no need to keep the cover plate in a bent state, thereby improving the assembly efficiency of the cable tray.

[0016] Preferably, a working ring is provided on one side of the partition plate close to the wiring cavity, and the working ring is hooked with an external tension spring to keep the cover plate between two adjacent partition plates in a compressed and bent state through the external tension spring.

[0017] By adopting the above technical solution, when operating other wiring cavities, the working ring on the partition plate can be hooked by an external tension spring, so that the wiring cavity that has completed wiring can be kept in a reduced state with the help of the elastic force of the tension spring, thereby making it easier to carry out wiring work.

[0018] Preferably, there are multiple central supports, and a splicing plate and a hanging frame are provided between two adjacent central supports. The splicing plates are coaxially rotatably connected, and the splicing plates are disc-shaped; the hanging frame is a U-shaped frame structure, and the end of the hanging frame at the opening is used to be connected to an external component. The inner side of the hanging frame is provided with a plate mounting groove, and the plate mounting groove is used for the splicing plate to be rotatably embedded.

[0019] By adopting the above technical solution, when maintenance work needs to be performed on a certain area of ​​the cable, the corresponding area of ​​the cable tray can be rotated, and other areas also need to be rotated a certain angle until the corresponding wiring cavity in the corresponding area is rotated to a predetermined direction. Therefore, the staff can perform maintenance work on the cables in different wiring cavities at a fixed position, which makes it easier to perform cable maintenance work.

[0020] Preferably, the splicing disk includes an inner core block, an outer ring, a connecting rod, a serial bolt and a serial nut, the inner core block is connected to the end face of the central support shaft; the inner side of the outer ring exceeds the area surrounded by the plurality of cover plates, the outer ring is embedded in the disk mounting groove, and the portion of the outer ring away from the inner core and not in the disk mounting groove is provided with a splicing hole, and the plurality of splicing holes are distributed at circular intervals around the center line of the outer ring; the connecting rod is a telescopic rod structure, one end of the connecting rod is threadedly connected to the outer side of the inner core block, and the other end is threadedly connected to the inner side of the outer ring; the rod portion of the serial bolt is penetrated by the splicing holes of the two outer rings, and the cap portion of the serial bolt abuts on the side of the outer ring away from each other; the serial nut is connected to the rod portion of the serial bolt, and the serial nut abuts on the side of the outer ring away from each other.

[0021] By adopting the above technical scheme, firstly, with the help of the outer ring, it is convenient for the staff to rotate the cable tray and also convenient for the staff to splice and install the cable tray at different positions; secondly, the two ends of the link rod are detachably connected to the inner core block and the outer ring, and different numbers of link rods and corresponding layouts of multiple link rods can be selected according to the number of wiring cavities; thirdly, with the help of series bolts and series bolts, there is a damped rotating connection structure between two adjacent outer rings, so when one part of the cable tray is rotated, the other parts will also rotate at a certain angle due to the damping, so the different positions of the cables can be adjusted synchronously, so that the maintenance work of the cable in a small area is more convenient.

[0022] Preferably, the serial nuts are made of elastic material.

[0023] By adopting the above technical solution, the range of the damping force between the splicing plates can be increased by means of the deformation of the serial nuts, so the transmission coefficient between different parts of the cable tray can be changed accordingly according to the different numbers of wiring cavities.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Because multiple partitions are evenly distributed around the center of the central support axis, there will be no interference in the line of sight between the wiring cavities, so the wiring operation can be carried out in different wiring cavities at the same time, thereby improving the wiring efficiency of the cable tray; 2. With the help of the cooperation between the clamping shaft groove and the connecting shaft, the detachable connection between the partition plate and the central support shaft is realized. Therefore, according to actual use requirements, different numbers of partition plates are spliced ​​accordingly to make cable trays with different numbers of wiring cavities.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] An embodiment of the present application discloses a cable tray that facilitates wiring.

[0033] Reference Figure 1 and Figure 2 The cable tray for convenient wiring includes a central support shaft 1, a partition plate 2 and a cover plate 3. The central support shaft 1 is cylindrical; the partition plate 2 is connected to the peripheral side of the central support shaft 1, and multiple partition plates 2 are evenly distributed in a circle around the center of the central support shaft 1; the cover plate 3 is connected to the end of the partition plate 2 away from the central support shaft 1, and the cover plate 3 is located between two adjacent partition plates 2. A wiring cavity 21 is formed between one cover plate 3 and two partition plates 2, and a cable is laid in one wiring cavity 21.

[0034] Reference Figure 1 and Figure 2 Because the plurality of partition plates 2 are evenly distributed in a circle around the center of the central support shaft 1, there will be no interference in vision between the wiring cavities 21, so wiring operations can be performed in different wiring cavities 21 at the same time, thereby improving the wiring efficiency of the cable tray.

[0035] Reference Figure 2 and Figure 3 In order to be able to assemble a cable tray of corresponding specifications according to the type of cable, the following settings are correspondingly arranged: a connecting ring 4 is sleeved on the circumferential side of the central support shaft 1, and a clamping shaft block 41 is connected to the circumferential side of the connecting ring 4. A plurality of clamping shaft blocks 41 are evenly distributed around the connecting ring 4 in a circle, and the clamping shaft block 41 is thinner at one end close to the connecting ring 4, and thicker at one end of the clamping shaft block 41 away from the connecting ring 4, so that a clamping shaft through groove 42 is formed between two adjacent clamping shaft blocks 41; a connecting shaft 22 is provided at one end of the partition plate 2 close to the central support shaft 1, and the connecting shaft 22 is clamped and penetrated in the clamping shaft through groove 42, and there is at least one clamping shaft through groove 42 between the connecting shafts 22 of two adjacent partition plates 2. Then, with the help of the cooperation between the clamping shaft through groove 42 and the connecting shaft 22, a detachable connection between the partition plate 2 and the central support shaft 1 is realized. Therefore, different numbers of partition plates 2 can be spliced ​​together according to actual use requirements to make a cable tray with different numbers of wiring cavities 21.

[0036] Reference Figure 2 and Figure 3 In order to maximize the operating space of the staff during the wiring process, the following settings are correspondingly arranged: the cover plate 3 is in the shape of a bendable thin plate, and the connecting shaft 22 is damped and rotated through the clamping shaft groove 42. When the wiring in one of the wiring cavities 21 has been completed, and the wiring work is being carried out on other wiring cavities 21, the partition plate 2 corresponding to the wiring cavity 21 where the wiring is completed can be rotated. In this process, the cover plate 3 will bend to reduce the volume of the wiring cavity 21, so the volume of the wiring cavity 21 being wired can be temporarily increased, thereby increasing the wiring field of view and improving the wiring efficiency.

[0037] Reference Figure 2 and Figure 4 In order to facilitate opening the cover 3 to maintain the cables in the wiring cavity 21, the following settings are correspondingly arranged: a clamping block 5, a clamping movable block 51 and an intermediate block 52 are arranged between the cover 3 and the partition plate 2, the clamping block 5 is fixedly connected to the end of the partition plate 2 away from the central support shaft 1; the clamping movable block 51 is bolted to the side of the clamping block 5 away from the partition plate 2; the intermediate block 52 is arranged on the cover 3, and the intermediate block 52 is clamped by the clamping block 5 and the clamping movable block 51, so that the assembly and disassembly between the cover 3 and the partition plate 2 can be realized from the circumferential direction, so it is also convenient to open the cover 3 later to carry out cable maintenance work.

[0038] Reference Figure 2 and Figure 4 In order to facilitate the fixation between the cover plate 3 and the partition plate 2, the following settings are correspondingly arranged: a clamping block 5 is cooperated with two clamping movable blocks 51, a clamping plate slot 53 is formed between a clamping movable block 51 and a clamping block 5, and the clamping plate slot 53 is a T-shaped slot structure. At the same time, the middle block 52 is made of elastic material, and the middle block 52 is inserted into the clamping plate slot 53. Before the cover plate 3 is connected to the partition plate 2, the clamping block 5 can be connected to the clamping movable block 51 first. When the cover plate 3 is installed later, it is only necessary to slide the middle block 52 from the ports at both ends of the clamping plate slot 53. Therefore, in the process of fixing the clamping block 5 and the clamping movable block 51, there is no need to keep the cover plate 3 in a bent state, thereby improving the assembly efficiency of the cable tray.

[0039] In addition, in the present embodiment, it is rather cumbersome for the staff to manually maintain the wiring cavity 21 that has already been wired in a temporarily reduced state, so a working ring 23 is provided on the side of the partition plate 2 close to the wiring cavity 21, and the working ring 23 is hooked by an external tension spring. The elastic force of the tension spring can then be used to keep the wiring cavity 21 that has already been wired in a reduced state, thereby making it easier to perform wiring work.

[0040] Reference Figure 1 and Figure 5In order to facilitate the maintenance of a certain area of ​​the cable, the following settings are correspondingly arranged: a plurality of central supports 1 are arranged, and a central support 1 is used as the minimum functional unit of the cable tray. The unit is set as a unit tray, and a splicing plate 6 and a hanging frame 7 are arranged between two adjacent central supports 1. The splicing plates 6 are coaxially rotatably connected, the splicing plate 6 is in the shape of a circular plate, and the hanging frame 7 is in a U-shaped frame structure. The end of the opening of the hanging frame 7 is connected to the external component, and a plate-mounting groove 71 is opened on the inner side of the hanging frame 7. The plate-mounting groove 71 is used for the splicing plate 6 to be rotatably embedded. When it is necessary to perform maintenance work on a certain area of ​​the cable, the corresponding unit tray can be rotated, and the other unit trays are also rotated by a certain angle until the corresponding wiring cavity 21 in the corresponding unit tray is rotated to a predetermined direction. Therefore, the staff can perform maintenance work on the cables in different wiring cavities 21 at a fixed position, thereby making it easier to perform cable maintenance work.

[0041] Reference Figure 1 and Figure 5 The splicing plate 6 includes an inner core block 61, an outer ring 62, a link rod 63, a series bolt 64 and a series nut 65. The inner core block 61 is coaxially fixedly connected to the end face of the central support shaft 1; the inner side of the outer ring 62 exceeds the area surrounded by multiple cover plates 3 in a unit bridge, and the outer ring 62 is embedded in the plate mounting groove 71. The portion of the outer ring 62 away from the inner core and not in the plate mounting groove 71 is provided with a splicing hole 621, and multiple splicing holes 621 are arranged around the center of the outer ring 62. The center lines are distributed at intervals in a circle; the link rod 63 is a telescopic rod structure, one end of the link rod 63 is threadedly connected to the outer side of the inner core block 61, and the other end is threadedly connected to the inner side of the outer ring 62; the rod of the series bolt 64 passes through the splicing holes 621 of the two outer rings 62, and the cap of the series bolt 64 abuts on the side of the outer ring 62 away from each other; the series nut 65 is connected to the rod of the series bolt 64, and the series nut 65 abuts on the side of the outer ring 62 away from each other.

[0042] Reference Figure 1 and Figure 5 The above structure of the splicing plate 6 has the following advantages. First, with the help of the outer ring 62, it is convenient for the staff to rotate the cable tray and also convenient for the staff to splice and install different positions of the cable tray; second, the two ends of the link rod 63 are detachably connected to the inner core block 61 and the outer ring 62, so different numbers of link rods 63 and the corresponding layout of multiple link rods 63 can be selected according to the number of wiring cavities 21; third, with the help of the series bolts 64 and the series bolts 64, the two adjacent outer rings 62 are connected with a damping rotation connection structure, so when one part of the cable tray is rotated, the other parts will also rotate at a certain angle due to the damping, so the different positions of the cables can be adjusted synchronously, so that the maintenance work of the cable in a small area is more convenient.

[0043] In addition, in the present embodiment, when the number of wiring cavities 21 is different, when one of the unit bridges is rotated to make the corresponding wiring cavity 21 face the predetermined position, the angles to be rotated of the other unit bridges are different. In order to adapt to this difference, the series nut 65 is made of elastic material, and the range of the damping force between the splicing plates 6 can be increased by means of the deformation of the series nut. Therefore, the transmission coefficient between different parts of the cable bridge can be changed accordingly according to the different number of wiring cavities 21, thereby making the cable maintenance work more convenient.

[0044] The implementation principle of the cable tray that is convenient for wiring in the embodiment of the present application is as follows: since a plurality of partition plates 2 are evenly distributed in a circle around the center of the central support shaft 1, there will be no line of sight interference between the wiring cavities 21, so wiring operations can be performed in different wiring cavities 21 at the same time, thereby improving the wiring efficiency of the cable tray.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
