Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a heat-insulating and flame-retardant trough-type cable tray. Background Technology

[0002] Cable trays, also known as cable management trays, are mainly divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays. They are used for cable laying and installation, making it convenient to support the cables. After the cables are laid inside the trough-type cable tray, they will not be exposed, thus increasing the aesthetics and providing a certain degree of protection for the cables.

[0003] Existing cable trays are usually made of aluminum alloy or stainless steel. Because they are supported by metal materials, they are easily ignited and heated by heat conduction in high-temperature environments such as fire scenes or factories, which can lead to cable fires. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a heat-insulating and flame-retardant cable tray to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating and flame-retardant trough-type cable tray, comprising a cable tray body, wherein a first heat insulation layer is connected inside the cable tray body, and slots are provided on both sides, both sides at the bottom, both sides inside, and the lower inside of the first heat insulation layer; an inner liner is connected to the top of the first heat insulation layer, and locking strips are fixed on both sides, the bottom of the inner liner, both sides inside the cable tray body, and the lower inside of the cable tray body; support strips are fixed on the upper sides of both sides of the cable tray body, and a cover plate is placed on the top of the support strip; a second heat insulation layer is connected inside the cover plate, and a buffer pad is connected to the bottom of the second heat insulation layer; four ear plates are fixed on the lower sides of both sides of the cable tray body respectively.

[0006] By adopting the above technical solution, during use, since both the first and second insulation layers are made of alumina ceramic material, they have good heat insulation performance and are fire-retardant, thus avoiding the impact of external high temperature or flame on the cables inside the cable tray. Furthermore, the first insulation layer is connected to the main body and inner liner of the cable tray by clips and grooves to bear longitudinal force, reducing the force on the alumina high-temperature adhesive and thus improving structural stability. Since the second insulation layer is an alumina honeycomb ceramic plate, the heat insulation performance is ensured while reducing the structural weight and thickness. At the same time, the buffer pad is set to prevent the first and second insulation layers from colliding, increasing protection. Moreover, the buffer pad is made of neoprene rubber, which has good flame retardancy.

[0007] Furthermore, the first heat insulation layer is fixedly connected to the cable tray body, inner liner and retaining strip by alumina high-temperature adhesive, and the second heat insulation layer is fixedly connected to the cover plate by alumina high-temperature adhesive.

[0008] By adopting the above technical solution, the first heat insulation layer can be effectively fixed to the cable tray body, inner liner and clips, and the second heat insulation layer can be fixed to the cover plate using alumina high-temperature adhesive.

[0009] Furthermore, the first insulation layer is an alumina ceramic plate, and the second insulation layer is an alumina honeycomb ceramic plate.

[0010] By adopting the above technical solution, it has good fire resistance and heat insulation properties. Furthermore, since the second insulation layer is an alumina honeycomb ceramic panel, the heat insulation performance is ensured while reducing the structural weight and thickness.

[0011] Furthermore, the main body, inner liner, clamping strip, support strip, cover plate, and ear plate of the cable tray are all made of stainless steel or aluminum alloy.

[0012] By adopting the above technical solution, the cable tray body, the first heat insulation layer and the inner liner form a bimetallic sandwich alumina ceramic structure, which has good fire resistance and heat insulation properties. The fire resistance and heat insulation properties of the cover plate are further enhanced by the setting of the second heat insulation layer.

[0013] Furthermore, the cushioning pad is made of neoprene rubber.

[0014] By adopting the above technical solution, the first insulation layer and the second insulation layer are prevented from colliding through the setting of the buffer pad, thus increasing the protection. In addition, the buffer pad is made of neoprene rubber, which has good flame retardancy.

[0015] Furthermore, two waist-shaped holes are formed on the outer surface of the ear plate.

[0016] By adopting the above technical solution, bolts are passed through the ear plate to assemble multiple cable trays together. The existence of the ear plate eliminates the need to open the waist-shaped hole on the side of the cable tray. Only the waist-shaped hole needs to be opened on the surface of the ear plate, thereby avoiding any impact on fire resistance and heat insulation.

[0017] Furthermore, the ear plate has a right-angled triangle cross-section and a "C"-shaped longitudinal section.

[0018] By adopting the above technical solution, the shape of the ear plate increases the structural strength, avoids the phenomenon of ear plate bending and deformation, and thus improves the connection stability.

[0019] Furthermore, a first lap plate is fixed to the bottom of the cable tray body, and a second lap plate is fixed to both sides of the bottom of the cable tray body.

[0020] By adopting the above technical solution, multiple cable trays can be connected together through the first and second lap plates while being connected, thereby distributing the longitudinal force evenly and reducing the radial force on the bolts on the ear plates.

[0021] Furthermore, the longitudinal sections of both the first lap plate and the second lap plate are isosceles triangles, and the first lap plate and the two second lap plates are staggered.

[0022] By adopting the above technical solution, multiple cable trays are joined together by the first and second lap plates, thereby distributing the longitudinal force evenly. The isosceles triangle increases the structural strength and prevents the first and second lap plates from bending and deforming.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the arrangement of the cable tray body, the first heat insulation layer, the inner liner, the retaining strip, and the retaining groove, forms a bimetallic sandwich alumina ceramic structure, which has good fire resistance and heat insulation properties. Furthermore, the first heat insulation layer and the cable tray body and inner liner bear longitudinal forces through the retaining strip and the retaining groove, reducing the force on the high-temperature alumina adhesive and thus improving structural stability; it has excellent fire resistance and heat insulation properties.

[0025] 2. This utility model, through the setting of support strips, cover plate, second heat insulation layer and buffer pad, increases the fire resistance and heat insulation of the cover plate by setting the second heat insulation layer. Since the second heat insulation layer is an alumina honeycomb ceramic plate, the heat insulation performance is ensured while reducing the structural weight and thickness. At the same time, the setting of buffer pad prevents the first heat insulation layer from colliding with the second heat insulation layer, increasing protection. Moreover, the buffer pad is made of neoprene rubber, which has good flame retardancy; further improving the fire resistance and heat insulation. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1:

[0034] A type of heat-insulated and flame-retardant cable tray, such as Figures 1-4 As shown, the cable tray includes a main body 1, with a first heat insulation layer 2 connected inside the main body 1. The first heat insulation layer 2 is an alumina ceramic plate. Slots 5 are provided on both sides, the bottom sides, the inner sides, and the lower inner side of the first heat insulation layer 2. An inner liner 3 is connected to the top of the first heat insulation layer 2. The first heat insulation layer 2 is fixedly connected to the main body 1, the inner liner 3, and the retaining strips 4 using alumina high-temperature adhesive. Retaining strips 4 are fixed on both sides, the bottom of the inner liner 3, the inner sides of the main body 1, and the lower inner side of the main body 1. Support strips 6 are fixed to the upper sides of both sides of the main body 1. A cover plate 7 is placed on the top of the support strip 6. A second heat insulation layer 8, also made of alumina honeycomb ceramic plate, is connected inside the cover plate 7. The second heat insulation layer 8 is fixedly connected to the cover plate 7 using alumina high-temperature adhesive. The bottom of the second heat insulation layer 8... The cable tray is connected to a buffer pad 9, which is made of neoprene rubber. During use, since both the first insulation layer 2 and the second insulation layer 8 are made of alumina ceramic material, they have good heat insulation performance and are fire-retardant. This prevents external high temperatures or flames from affecting the cables inside the cable tray. The first insulation layer 2 is connected to the cable tray body 1 and the inner liner 3 by the clamping strip 4 and the clamping groove 5 to bear the longitudinal force, reducing the force on the alumina high-temperature adhesive and thus improving structural stability. Since the second insulation layer 8 is an alumina honeycomb ceramic plate, it ensures heat insulation performance while reducing structural weight and thickness. At the same time, the buffer pad 9 prevents the first insulation layer 2 from colliding with the second insulation layer 8, increasing protection. The buffer pad 9 is made of neoprene rubber and has good flame retardancy.

[0035] See Figures 1-4In the above embodiment, four ear plates 10 are fixed on the lower sides of the cable tray body 1. The cable tray body 1, inner liner 3, clip 4, support strip 6, cover plate 7 and ear plates 10 are all made of stainless steel or aluminum alloy. Two waist-shaped holes are opened on the outer surface of the ear plate 10. The cross-section of the ear plate 10 is a right triangle and the longitudinal section of the ear plate 10 is "C". The workers connect multiple cable trays and then pass bolts through the ear plates 10 to assemble the multiple cable trays together. The existence of the ear plates 10 eliminates the need to open waist-shaped holes on the side of the cable tray. Only waist-shaped holes need to be opened on the surface of the ear plates 10, thereby avoiding the impact on fire resistance and heat insulation. Moreover, the shape of the ear plates 10 increases the structural strength and prevents the ear plates 10 from bending and deforming, thereby improving the connection stability.

[0036] Example 2:

[0037] Based on the above embodiment one, the following settings are now implemented to increase connection stability.

[0038] See Figure 1 and Figure 2 In the above embodiment, a first overlapping plate 11 is fixed at the bottom of the cable tray body 1, and a second overlapping plate 12 is fixed on both sides of the bottom of the cable tray body 1. The longitudinal sections of the first overlapping plate 11 and the second overlapping plate 12 are both isosceles triangles. The first overlapping plate 11 and the two second overlapping plates 12 are staggered. When multiple cable trays are connected, they are connected together by the first overlapping plate 11 and the second overlapping plate 12, thereby distributing the longitudinal force evenly and reducing the radial force on the bolts on the ear plate 10.

[0039] The implementation principle of this utility model is as follows: First, the workers connect multiple cable trays together, and then bolts are passed through the ear plate 10 to assemble the multiple cable trays together. The existence of the ear plate 10 eliminates the need to open the waist-shaped hole on the side of the cable tray, and only the waist-shaped hole needs to be opened on the surface of the ear plate 10, thereby avoiding the impact on fire resistance and heat insulation. Moreover, the shape of the ear plate 10 increases the structural strength and prevents the ear plate 10 from bending and deforming, thereby improving the connection stability. At the same time as the multiple cable trays are connected, the multiple cable trays are overlapped together by the first overlapping plate 11 and the second overlapping plate 12, thereby evenly distributing the longitudinal force and reducing the radial force on the bolts on the ear plate 10.

[0040] After the cable tray is installed, the staff removes the cover plate 7 from the support bar 6. Then the staff can lay the cable inside the main body 1 of the cable tray. After the cable is laid, the staff puts the cover plate 7 back. During this process, the support bar 6 supports the cover plate 7.

[0041] During use, since both the first insulation layer 2 and the second insulation layer 8 are made of alumina ceramic material, they have good heat insulation performance and are fire-retardant, thus preventing external high temperatures or flames from affecting the cables inside the cable tray. Furthermore, the first insulation layer 2 is connected to the cable tray body 1 and the inner liner 3 by the clamping strip 4 and the clamping groove 5 to bear the longitudinal force, reducing the force on the alumina high-temperature adhesive and thus improving structural stability. Since the second insulation layer 8 is an alumina honeycomb ceramic plate, it ensures heat insulation performance while reducing structural weight and thickness. At the same time, the buffer pad 9 prevents the first insulation layer 2 from colliding with the second insulation layer 8, increasing protection. The buffer pad 9 is made of neoprene rubber, which has good flame retardancy.
