Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," "longitudinal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0024] This application provides a cable tray that uses a combined splicing method, which has the characteristics of strong applicability and reusability, and solves the problem of low applicability and usability of the prior art.

[0025] like Figure 1 As shown, a cable tray includes a cable tray body. For example, the cable tray body can be rectangular, trapezoidal, or other shapes. This application does not make specific limitations. The width and height of the cable tray body can be determined according to the actual amount of cables used.

[0026] like Figure 1 and Figure 2 As shown, the cable tray body includes a bracket 1, a base plate 2, a first side plate 3, a second side plate 4, a first side support 5, a second side support 6, and a cover plate 7. At least two brackets 1 are provided, with a gap between adjacent brackets 1, and the brackets 1 are used to provide support for other structures.

[0027] like Figure 2 As shown, the bottoms of two adjacent brackets 1 are detachably connected by a base plate 2, the first sides of two adjacent brackets 1 are detachably connected by a first side plate 3, and the second sides of two adjacent brackets 1 are detachably connected by a second side plate 4; the first side support 5 is detachably connected to the top of the first side of each bracket 1, the second side support 6 is detachably connected to the top of the second side of each bracket 1, and the cover plate 7 is detachably connected to the first side support 5 and the second side support 6.

[0028] In this application, two adjacent brackets 1 are connected by a base plate 2, a first side plate 3, and a second side plate 4, forming a cavity for accommodating cables. The structure is simple and easy to install and disassemble.

[0029] The cover plate 7 is detachably connected to the first side support 5 and the second side support 6. After the cable is installed inside the cable tray body, the cover plate 7 is fixedly connected to the first side support 5 and the second side support 6 by bolts. When the cable needs to be replaced, the cover plate 7 is removed from the first side support 5 and the second side support 6. For example, the cover plate 7 can be made of cold-rolled steel plate, and the thickness can be determined according to the actual strength requirements.

[0030] like Figure 3 As shown, when the two cable tray bodies are spliced ​​together, the first cable tray body and the second cable tray body are detachably connected. The first cable tray body and the second cable tray body share a bracket 1, and the two cable tray bodies are spliced ​​together in series by sharing the bracket 1.

[0031] like Figure 3 As shown, for example, when the first cable tray body and the second cable tray body are spliced ​​together, the second cable tray body can be spliced ​​to the left side of the first cable tray body, and the second cable tray body and the first cable tray body share the bracket 1 on the left side of the first cable tray body. The second cable tray body can also be spliced ​​to the right side of the first cable tray body, and the second cable tray body and the first cable tray body share the bracket 1 on the right side of the first cable tray body.

[0032] like Figure 3 As shown, for example, each cable tray body has 3 brackets 1. The third bracket 1 of the first cable tray body serves as the first bracket 1 of the second cable tray body and is connected to the base plate 2, the first side plate 3, the second side plate 4, the first side support 5, and the second side support 6, thereby completing the splicing of the two cable tray bodies.

[0033] The cable tray body of this application can be prefabricated, has a simple structure, and high assembly efficiency. Multiple cable tray bodies can be combined and spliced ​​as needed, solving the problems of on-site transportation and installation, as well as the need for cutting excessively large sizes, thus reducing waste costs.

[0034] like Figure 4 As shown, for example, the bracket 1 includes a crossbeam 101, a crossarm 102, a first support beam 103, and a second support beam 104. The bottom of the first support beam 103 and the bottom of the second support beam 104 are detachably connected to the two ends of the crossbeam 101 in the first direction to form a U-shaped structure. The first support beam 103 and the second support beam 104 bear the load in the horizontal direction to prevent the cable tray body from deforming under force. The two ends of the crossarm 102 in the first direction are respectively supported on the top of the first support beam 103 and the top of the second support beam 104.

[0035] like Figure 5 As shown, the first direction is the length direction of the crossbeam 101 and the crossarm 102.

[0036] like Figure 5 and Figure 6As shown, the crossbeams 101 of two adjacent brackets 1 are detachably connected via the base plate 2, as follows: Figure 7 As shown, the first support beams 103 of two adjacent brackets 1 are detachably connected by the first side plate 3; the second support beams 104 of two adjacent brackets 1 are detachably connected by the second side plate 4, forming a cavity with a U-shaped cross-section for accommodating cables.

[0037] The first side support 5 is detachably connected to the top of the first support beam 103 of each bracket 1, and the second side support 6 is detachably connected to the top of the second support beam 104 of each bracket 1. The first side support 5 and the second side support 6 fix the multiple brackets 1 into a whole.

[0038] like Figure 5 As shown, the two ends of the crossbeam 102 of each bracket 1 abut against the first side bracket 5 and the second side bracket 6 respectively. The crossbeam 102 bears the horizontal load and prevents the trunking body from deforming under force. The crossbeam 102 also provides support for the cover plate 7 and prevents the cover plate 7 from being deformed under pressure.

[0039] like Figure 6 As shown, for example, the two ends of the base plate 2 in the second direction are detachably connected to the top of the crossbeams 101 of the two adjacent brackets 1. For example, the base plate 2 is provided with at least one first through hole at both ends in the second direction, and the crossbeam 101 is provided with a second through hole at the position corresponding to the first through hole. The base plate 2 and the top of the crossbeam 101 are fixedly connected by bolts passing through the first through hole and the second through hole.

[0040] like Figure 6 As shown, the second direction is the length direction of the base plate 2, and the second direction is perpendicular to the first direction.

[0041] like Figure 6 As shown, for example, the base plate 2 is provided with a boss 201 facing the inside of the bracket 1, and the boss 201 is provided with a plurality of first heat dissipation holes 202. The plurality of first heat dissipation holes 202 are arranged in an array. For example, the shape of the first heat dissipation holes 202 can be set as waist-shaped.

[0042] By providing a first heat dissipation hole 202 on the base plate 2, heat dissipation and ventilation at the bottom of the cable are ensured. At the same time, the protrusion 201 on the base plate 2 increases the isolation gap with the outer surface, reducing surface heat conduction. Meanwhile, the base plate 2 is connected to the top of the crossbeam 101, and the base plate 2 is raised from the ground by the crossbeam 101, improving the heat dissipation effect.

[0043] The cable tray body of this application has strong heat insulation capabilities, and the internal assembly connection can reduce external heat conduction, taking into account outdoor sun protection and improving internal heat insulation capabilities.

[0044] like Figure 7As shown, for example, the first side plate 3 and the second side plate 4 have the same structure. The outer side of the first side plate 3 is flush with the outer side of the first support beam 103, and the outer side of the second side plate 4 is flush with the outer side of the second support beam 104.

[0045] like Figure 8 As shown, the first side plate 3 has a first bending portion 301 on both sides in the second direction, and the first bending portion 301 is detachably connected to the first support beam 103.

[0046] For example, a third through hole is provided on the first bent part, and a fourth through hole is provided on the first support beam 103 at the position corresponding to the third through hole. The first bent part and one side of the first support beam 103 are fixed by bolts passing through the third through hole and the fourth through hole, thereby realizing the fixed connection between the first side plate 3 and the first support beam 103.

[0047] like Figure 9 As shown, the second side plate 4 has a second bend 401 on both sides in the second direction. The second bend 401 is detachably connected to the second support beam 104. The specific connection is the same as the connection between the first bend and the first support beam 103, and will not be described again.

[0048] In this embodiment, by providing bending portions in the second direction of the first side plate 3 and the second side plate 4, the side plates are connected to the support beam, while the outer surfaces of the side plates are flush with the outer surfaces of the support beam, ensuring the aesthetics of the cable tray. The first side plate 3 and the second side plate 4 form a cavity by providing the first bending portion and the second bending portion, which also increases the spacing between the side plates and the internal cables, improving protection and heat dissipation space.

[0049] like Figure 6 and Figure 7 As shown, the length direction of the first side plate 3 and the second side plate 4 is the same as the length direction of the base plate 2. Therefore, the second direction of the base plate 2 is the second direction of the first side plate 3 and the second side plate 4.

[0050] like Figure 8 and Figure 9 As shown, for example, the first side plate 3 has a third bend 302 at both ends in the third direction, and the second side plate 4 has a fourth bend 4 on both sides in the third direction. The third bend and the fourth bend 402 near the bottom plate 2 can fill the gap between the side plate and the bottom plate 2, making the groove look nice. The third bend and the fourth bend 402 near the cover plate 7 can support the first side support 5 or the second side support 6.

[0051] like Figure 7 As shown, the third direction is the width direction of the first side plate 3 and the second side plate 4, and the third direction is perpendicular to the second direction.

[0052] like Figure 7As shown, for example, multiple louvered holes 303 are provided on the outer surfaces of the first side plate 3 and the second side plate 4. The multiple louvered holes 303 are arranged in an array. By providing louvered holes 303 on the first side plate 3 and the second side plate 4, outdoor rainwater is prevented from entering the inside of the cable tray body, and heat dissipation is also effectively achieved.

[0053] For example, the crossbeam 101, crossarm 102, first support beam 103 and second support beam 104 are all made of square tubing, and the specific model of the square tubing can be selected according to the actual strength requirements.

[0054] like Figure 4 As shown, for example, the bottom of the first support beam 103 is detachably connected to one end of the crossbeam 101 in the first direction via a connector 8, and the bottom of the second support beam 104 is detachably connected to the other end of the crossbeam 101 in the first direction via a connector 8.

[0055] like Figure 5 As shown, for example, the lengths of the first side support 5 and the second side support 6 are both less than the distance between the first bracket 1 and the last bracket 1. One end of the first side support 5 is detachably connected to the top of the first side of the first bracket 1 via a connector 8. For example, one end of the connector 8 is connected to the first side support 5, and the other end is connected to the top of the first support beam 103 of the first bracket 1.

[0056] like Figure 10 As shown, the other end of the first side support 5 is detachably connected to the last bracket 1 via a reinforcing member 9. The connection point is located on the side of the first side plate 3 away from the bottom plate 2. For example, one end of the reinforcing member 9 is connected to the first side support 5, and the other end is connected to the first support beam 103 of the last bracket 1 at the upper part of the first side plate 3.

[0057] One end of the second side support 6 is detachably connected to the top of the second side of the first bracket 1 via a connector 8. For example, one end of the connector 8 is connected to the second side support 6, and the other end is connected to the top of the second support beam 104 of the first bracket 1.

[0058] The other end of the second side support 6 is detachably connected to the last bracket 1 via a reinforcement 9. The connection is located on the side of the second side plate 4 away from the bottom plate 2. For example, one end of the reinforcement 9 is connected to the second side support 6, and the other end is connected to the second support beam 104 of the last bracket 1 at the upper part of the second side plate 4.

[0059] When the two cable tray bodies are spliced, the top of the first side of the shared bracket 1 on the first cable tray body is detachably connected to one end of the first side support 5 of the second cable tray body through the connector 8; the top of the second side of the shared bracket 1 on the first cable tray body is detachably connected to one end of the second side support 6 of the second cable tray body through the connector 8.

[0060] like Figure 4As shown, for example, the inner side of the first support beam 103 and the inner side of the second support beam 104 are both provided with support members 10, one end of the crossbeam 102 is supported on the support member 10 of the first support beam 103, and the other end of the crossbeam 102 is supported on the support member 10 of the second support beam 104.

[0061] The connector 8, reinforcement 9, and support 10 in this embodiment all serve a connecting and supporting function, mainly to strengthen the stability of the cable tray body.

[0062] like Figure 11 As shown, for example, the connector 8 includes a first L-shaped plate 81 and a first reinforcing rib 82. The first L-shaped plate 81 includes a first connecting plate and a second connecting plate that are connected to each other. The first connecting plate and the second connecting plate are also connected by two first reinforcing ribs 82. Both the first connecting plate and the second connecting plate are provided with a sixth through hole, which is used to bolt the structure to be connected.

[0063] When the bottom of the first support beam 103 is connected to the crossbeam 101 via the connector 8, the connector 8 is located inside the first support beam 103. The first connecting plate is fixedly connected to one side of the inner wall of the first support beam 103 by bolts. The bottom of the second connecting plate is flush with the bottom of the first support beam 103. The crossbeam 101 is connected to the second connecting plate by bolts. The connection of any other two structures via the connector 8 is the same as the above concept and will not be described again.

[0064] like Figure 12 As shown, for example, the reinforcement 9 includes a second L-shaped plate 91 and a second reinforcing rib 92. The second L-shaped plate 91 includes a third connecting plate and a fourth connecting plate that are connected to each other. The third connecting plate and the fourth connecting plate are also connected by two second reinforcing ribs 92. Both the third connecting plate and the fourth connecting plate are provided with a seventh through hole, which is used to bolt the structure to be connected.

[0065] When the first side support 5 is connected to one side of the first support beam 103 via the reinforcement 9, the third connecting plate is fixedly connected to one outer side of the first support beam 103 via bolts, and the fourth connecting plate is fixedly connected to the bottom of the first side support 5 via bolts. The connection of any other two structures via the reinforcement 9 is the same as the above concept and will not be described again.

[0066] like Figure 13As shown, for example, the support member 10 includes a third L-shaped plate 1001 and a limiting plate 1002. The third L-shaped plate 1001 includes a fifth connecting plate and a sixth connecting plate that are connected to each other. An eighth through hole is provided on the fifth connecting plate. Two limiting plates 1002 are provided. Both limiting plates 1002 are provided on the side of the sixth connecting plate facing away from the fifth connecting plate. There is a gap between the two limiting plates 1002. One end of the crossbeam 102 is located within the gap between the two limiting plates 1002. The bottom of one end of the crossbeam 102 contacts the sixth connecting plate. Bolts pass through the eighth through hole on the fifth connecting plate and are fixedly connected to the inner side of the first support beam 103 or the inner side of the second support beam 104.

[0067] The structure of the connector 8, the reinforcement 9 and the support 10 described above is an example of this application. Other structures may also be adopted under the technical concept of this application, and this application does not make any specific limitations.
