Description

Technical Field

[0001] This utility model relates to a cable tray, specifically a high-strength cable tray equipped with a polymer alloy inner steel plate. Background Technology

[0002] Cable trays are structural devices specifically designed to support, protect, and manage cable lines. Typically made of metal, they form a closed or open channel, providing orderly laying space for cables while resisting external environmental interference (such as mechanical impact, moisture, and corrosion). They are one of the core infrastructure components for cable laying in fields such as power, communications, and industrial control.

[0003] Cable trays typically consist of a housing and a cover; the channel formed by the housing and cover is used for cable routing. In some special environments, a high-molecular-weight alloy steel plate is fixedly installed inside the housing to enhance the cable tray's protection of the cables and improve electrical safety. Usually, the cables are placed directly inside the housing, allowing them to move freely.

[0004] Because cables can vibrate naturally within the cable tray (unforced periodic vibrations caused by the cable's own characteristics (such as mass, stiffness, and damping) or external excitations (such as airflow and mechanical vibration) during operation or in the environment are common dynamic phenomena in cable tray systems), for high-strength cable trays equipped with polymer alloy inner lining steel plates, cable vibration can not only affect the long-term reliability of the cable tray structure, but also aggravate the damage to the inner lining coating, thereby threatening the safe operation of the cable. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength cable tray with a polymer alloy inner steel liner to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-strength cable tray with a polymer alloy inner lining steel plate includes a box body and a cover plate; the cover plate and the box body are connected by a snap-fit ​​structure. A steel plate is installed on the inner wall of the enclosure, and multiple sets of partitions are installed on the steel plate; the partitions divide the enclosure into multiple cable compartments; the steel plate is made of a polymer alloy. It also includes multiple sets of fasteners, which are installed in the cable chamber, including multiple sets of limiting plates that are rotatably installed on the partition.

[0012] The high-strength cable tray with a polymer alloy inner steel plate as described above: the support block has a groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: after the cable is installed, the limiting plate will squeeze the cable, thereby preventing the cable from accidentally detaching from the cable chamber, thus improving the protection of the cable and effectively increasing the service life of the cable and the cable tray; and by squeezing the cable with the limiting plate, the resistance of the cable moving in the cable chamber can be increased, thereby reducing the friction frequency between the cable and the steel plate, thus reducing the loss of polymer alloy; through the elastic force of the tension spring, the vibration (vortex-induced vibration, parametric vibration, etc.) generated by the cable during power use can be offset or eliminated, thereby reducing the loss of polymer alloy steel plate.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-6 As one embodiment of this utility model, the high-strength cable tray equipped with a polymer alloy inner steel plate includes a box body 1 and a cover plate 2; the cover plate 2 and the box body 1 are connected by a snap-fit ​​structure. A steel plate 3 is installed on the inner wall of the enclosure 1, and multiple sets of partitions 4 are installed on the steel plate 3; the partitions 4 divide the enclosure 1 into multiple sets of cable compartments 11; the steel plate 3 is made of polymer alloy material. It also includes multiple sets of fasteners, which are installed inside the cable chamber 11, including multiple sets of limiting plates 902 that are rotatably installed on the partition plate 4.

[0023] In this embodiment, the housing 1 and the cover plate 2 are connected by a snap-fit ​​structure to load cables; the cables are physically enclosed to isolate them from the external environment, thereby fixing and protecting the cables and preventing them from being damaged by the external environment.

[0024] Steel plate 3 is made of high-molecular alloy, which can effectively improve the mechanical strength of the cable tray, thereby reducing the probability of the cable tray deforming under stress; and the high-molecular alloy material can avoid the risk of leakage caused by accidental electrification of metal cable trays (such as induced current, static electricity accumulation); even if the cable is damaged and short-circuited, the inner lining can isolate the current and protect the safety of maintenance personnel.

[0025] The enclosure 1 is divided into multiple cable compartments 11 by the partition 4, so that the cables can be installed independently, thereby avoiding mutual interference between multiple cables and improving the stability of power supply.

[0026] When installing cables, the cables are placed horizontally into the cable chamber 11. During this process, the movement of the cables will cause the limiting plate 902 to rotate. When the cables come into contact with the steel plate 3, the limiting plate 902 will squeeze the cables, thereby preventing the cables from accidentally detaching from the cable chamber 11. This improves the protection of the cables and effectively extends the service life of both the cables and the cable tray. Furthermore, by squeezing the cables with the limiting plate 902, the resistance to the movement of the cables in the cable chamber 11 is increased, thereby reducing the friction frequency between the cables and the steel plate 3 and thus reducing the loss of the polymer alloy.

[0027] As a further embodiment of this utility model, the snap-fit ​​structure includes a fitting block 101 installed on the housing 1; the cover plate 2 is provided with a fitting groove 201 that can snap into the fitting block 101.

[0028] In this embodiment, the cover plate 2 is elastic. After the cable is installed, the cover plate 2 is placed on the housing 1 and an external force is applied to make the cover plate 2 gradually approach the steel plate 3. During this process, the cover plate 2 will undergo elastic deformation under the squeezing action of the interlocking block 101, thereby facilitating the interlocking block 101 to cooperate with the interlocking groove 201. And when the interlocking block 101 enters the interlocking groove 201, the cover plate 2 will elastically recover, thereby increasing the cooperation strength between the interlocking block 101 and the interlocking groove 201 (that is, through the mutual squeezing of the interlocking block 101 and the groove wall of the interlocking groove 201, the probability of the cover plate 2 separating from the housing 1 can be reduced).

[0029] The interlocking block 101 and the interlocking groove 201 cooperate with each other to increase the protection strength of the cable tray for the cable and reduce the impact of the external environment on the cable.

[0030] As a further embodiment of this utility model, the fixing member also includes a connecting plate 8 installed on the partition 4; a rotating sleeve 9 is rotatably installed on the connecting plate 8; a limiting plate 902 is installed on the rotating sleeve 9; and a trigger plate 901 is installed on the rotating sleeve 9.

[0031] As a further embodiment of this utility model, the angle between the trigger plate 901 and the limiting plate 902 is a right angle.

[0032] In this embodiment, the limiting plate 902 is initially tilted, so the trigger plate 901, which is at a right angle to the limiting plate 902, is also tilted. Connecting plates 8 are installed on both partitions 4 of a cable chamber 11, and the connecting plates 8 are symmetrically arranged. Therefore, the limiting plate 902 and the trigger plate 901 on the rotating sleeve 9, which is rotatably mounted thereon, are also symmetrically arranged.

[0033] The symmetrical trigger plates 901 are set on the trajectory of the cable movement. Therefore, during the cable installation process, the cable will come into contact with the trigger plates 901, thereby causing the trigger plates 901 to rotate, which in turn causes the limit plate 902 to rotate through the rotating sleeve 9.

[0034] When the cable comes into contact with the steel plate 3, the trigger plate 901 is perpendicular to the steel plate 3, while the limiting plate 902 is parallel to the steel plate 3; at this time, the cable is located within the angle between the trigger plate 901 and the limiting plate 902.

[0035] During cable installation, the movement of the cable drives the rotation of the limiting plate 902, effectively improving installation efficiency and avoiding repetitive fixing actions by operators, thereby reducing installation costs. After cable installation, the limiting plate 902 compresses the cable, increasing the difficulty of the cable detaching from the cable chamber 11, thus improving cable protection and effectively extending the service life of both the cable and the cable tray. Furthermore, the compression of the cable by the limiting plate 902 increases the resistance to cable movement within the cable chamber 11, thereby reducing the friction frequency between the cable and the steel plate 3 and reducing polymer alloy loss.

[0036] As a further embodiment of this utility model, the fixing component also includes a first connecting post 801 installed on the connecting plate 8; a second connecting post 903 is installed on the limiting plate 902; the first connecting post 801 and the second connecting post 903 are connected by a tension spring 10.

[0037] In this embodiment, the equilibrium position is such that the axis of the second connecting post 903 is located on the line connecting the axis of the first connecting post 801 and the axis of the rotating sleeve 9.

[0038] In the initial state, the second connecting post 903 is located above the equilibrium position. At this time, the tension of the tension spring 10 will act on the limiting plate 902, causing the limiting plate 902 to tilt and abut against the partition 4.

[0039] When the cable is installed, the cable moves and drives the trigger plate 901 to rotate, which in turn drives the limit plate 902 to rotate through the rotating sleeve 9. During this process, the second connecting post 903 will gradually approach the equilibrium position, thereby stretching the tension spring 10 to increase the tension.

[0040] When the second connecting post 903 passes the equilibrium position (the second connecting post 903 moves below the equilibrium position), the tension of the tension spring 10 will drive the limiting plate 902 to rotate, so that the limiting plate 902 squeezes the cable. When the cable comes into contact with the steel plate 3, the limiting plate 902 squeezes the cable tightly under the action of the tension spring 10, thereby increasing the resistance of the cable to leaving the cable chamber 11, thus improving the protection of the cable and effectively improving the service life of the cable and the cable tray. Moreover, by squeezing the cable with the limiting plate 902, the resistance of the cable moving in the cable chamber 11 can be increased, thereby reducing the friction frequency between the cable and the steel plate 3, thus reducing the loss of polymer alloy.

[0041] Furthermore, the elastic force of the tension spring 10 can offset or eliminate the vibration (vortex-induced vibration, parametric vibration, etc.) generated by the cable during power use, thereby reducing the loss of the polymer alloy steel plate 3.

[0042] As a further embodiment of this utility model, multiple sets of fixing plates 5 are installed on the partition plate 4, a slider 501 is installed on the fixing plate 5, a support block 6 is provided on the fixing plate 5, a groove 601 is provided on the support block 6 to slide and engage with the slider 501, and a spring 7 is installed at the bottom of the support block 6 to be fixedly connected to the steel plate 3.

[0043] In this embodiment, during cable installation, the middle part of the cable located in the cable tray contacts the support block 6; under the weight of the cable, the support block 6 will move closer to the steel plate 3, during which the slider 501 will slide in the groove 601; and the spring 7 will be compressed.

[0044] After the cable is installed, it takes the shape of an arc under the support of the support block 6. Therefore, when the cable is stretched or contracted due to environmental factors (such as thermal expansion and contraction, or human stretching), the squeezing force of the cable on the support block 6 will increase or decrease. At this time, under the elastic force of the spring 7, the support block 6 will move closer to or further away from the steel plate 3, thereby continuing to support the cable and preventing the cable from being misaligned.

[0045] As a further improvement of this utility model, the support block 6 is provided with a groove 602.

[0046] In this embodiment, after the cable is completed, it is located in the groove 602. The groove 602 increases the resistance to cable movement, thereby preventing the bent cables from affecting each other, thus improving the cable tray's ability to protect the cables.

[0047] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
