Description

Technical Field

[0001] This invention belongs to the field of cable tray technology, and particularly relates to an adjustable cable tray device for cable trenches. Background Technology

[0002] Cable trenches, as underground channels for laying and protecting cables, play a vital role in ensuring the safe operation of cables and facilitating subsequent inspection and maintenance. Cable trays are usually installed inside cable trenches to support and position the cables, preventing them from directly contacting the trench bottom or walls and suffering wear, corrosion, or compression, thus ensuring the insulation performance and service life of the cables.

[0003] Existing cable tray devices typically consist of a fixed bracket, a support plate, and connecting components. The fixed bracket is directly fixed to the side wall or bottom of the cable trench, and the support plate is installed on the fixed bracket through the connecting components to form a support plane for placing cables.

[0004] However, existing cable tray devices have certain drawbacks in actual use: First, most existing support plates are designed with a fixed length, making it difficult to flexibly adjust the support range according to the number of cables, which can easily lead to excessive stretching or compression of the cables due to uneven stress; Second, most existing support plates are fixed on fixed brackets, making it impossible to adjust the angle in the horizontal direction, which cannot meet the convenient use requirements of complex cable trenches, resulting in poor cable laying efficiency.

[0005] Therefore, in view of the above situation, there is an urgent need to develop an adjustable cable tray device for cable trenches to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an adjustable cable tray device for cable trenches to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An adjustable cable tray device for cable trenches includes a fixing plate and further includes: A locking mechanism, which is fixed to a fixed plate; Multiple bracket modules are provided, with adjacent bracket modules interlocking with each other. Each bracket module consists of a bracket plate and an assembly mechanism. The assembly mechanism is installed at the bottom of the bracket plate, and the bracket plate at the rear end is fixedly connected to a locking mechanism. A groove is provided in the middle of the bracket plate, and an arc-shaped baffle is provided on one side of the bracket plate at the front end. The locking mechanism is used to adjust the horizontal angle of the multiple bracket modules and fix the multiple bracket modules to the fixing plate. The assembly mechanism includes a locking component and a locking component. The locking component and the locking component are respectively fixed on the front and rear ends of the bottom of the same bracket plate. The locking components and locking components on adjacent bracket plates lock into each other and complete the quick connection of adjacent bracket modules.

[0008] As a further technical solution of the present invention, the engaging assembly includes a lower mounting plate, an upper mounting plate, an engaging component, a pin, and a torsion spring. The upper mounting plate and the lower mounting plate are spliced ​​together and locked to the bottom of the bracket plate with the same screw. An engaging cavity is provided in the middle of both the upper and lower mounting plates. Release cavities are also symmetrically provided on the upper and lower mounting plates. The two release cavities are located on both sides of the engaging cavity, and a connecting groove is provided between the release cavity and the engaging cavity. A pin is fixed to the inner wall of the engaging cavity on the lower mounting plate. An engaging component is rotatably installed on the outer side of the pin. A torsion spring is provided between the pin and the engaging component. The two ends of the torsion spring are respectively connected to the inner wall of the engaging component and the outer wall of the pin. One end of the engaging component engages with the engaging assembly, and the other end of the engaging component passes through the connecting groove and extends into the release cavity. The middle part of the engaging component contacts the inner wall of the engaging cavity.

[0009] As a further technical solution of the present invention, the engaging component is composed of an engaging sleeve, an engaging block, a limiting plate, and a release plate. The engaging sleeve is mounted on a pin and connected to a torsion spring. The engaging sleeve is fixed with the engaging block, the limiting plate, and the release plate respectively. The engaging block is located in the engaging cavity and cooperates with the engaging assembly. The limiting plate is located in the engaging cavity and contacts the inner wall of the engaging cavity. One end of the release plate passes through the connecting groove and extends into the release cavity.

[0010] As a further technical solution of the present invention, the snap-fit ​​assembly includes a fixing seat, a snap-fit ​​post, and a snap-fit ​​groove. The fixing seat is fixed to the bottom of the bracket plate. A snap-fit ​​post is fixed on one end face of the fixing seat near the snap-fit ​​block. Snap-fit ​​grooves that cooperate with the snap-fit ​​block are equidistantly opened on both sides of the snap-fit ​​post. The spacing between adjacent snap-fit ​​grooves is consistent with that between adjacent snap-fit ​​blocks.

[0011] As a further technical solution of the present invention, the locking mechanism includes a locking component and a connecting component. The locking component is mounted on a fixed plate, one end of the connecting component is rotatably mounted in the middle of the locking component, and the other end of the connecting component is connected to the bracket module at the tail end.

[0012] As a further technical solution of the present invention, the locking assembly includes an ear plate, a locking stud, an upper locking block, and a lower locking block. The ear plate is vertically fixed on the fixing plate, the locking stud is threadedly connected to the ear plate, one end of the locking stud is fixed with the upper locking block, and the other end of the locking stud is slidably mounted with the lower locking block. One end of the connecting assembly is located between the upper locking block and the lower locking block and cooperates with the upper locking block and the lower locking block respectively.

[0013] As a further technical solution of the present invention, the connecting assembly includes a locking sleeve, a clamping plate, a locking groove, an annular plate, and a locking spring. The locking sleeve is located outside the locking stud and between the upper locking block and the lower locking block. A clamping plate fixedly connected to the tail end bracket module is fixed on the outer wall of the locking sleeve. Locking grooves are provided on the inner walls of both the upper and lower ends of the locking sleeve. The two locking grooves respectively cooperate with the upper locking block and the lower locking block. An annular plate is fixed in the middle of the inner wall of the locking sleeve. The annular plate is connected to the lower locking block through the locking spring.

[0014] As a further technical solution of the present invention, the locking groove adopts a frustum-shaped groove, and both the upper locking block and the lower locking block adopt a frustum-shaped block structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The snap-fit ​​components on adjacent bracket plates interlock with each other, enabling quick connection of adjacent bracket modules. This plug-and-play connection method effectively shortens the installation time of bracket modules, improves the efficiency of bracket device disassembly and modification, and facilitates later maintenance and replacement. When a bracket module is damaged, it can be disassembled and replaced individually without affecting other modules, reducing interference with the overall cable laying system and lowering maintenance costs. Due to the modular design of the bracket plate, the number of bracket modules can be freely increased or decreased according to the cable laying requirements. This feature breaks the limitations of traditional fixed-length brackets. When the number of cables to be laid is small, only a few bracket modules need to be installed to meet the support requirements, which can avoid material waste and reduce the space occupied by the bracket device in the cable trench. If it is necessary to expand the capacity or increase the number of cables in the future, the required number of bracket modules can be added adaptively without large-scale modification of the original device structure. This greatly improves the adaptability of the device in different engineering stages, reduces the cost loss caused by early planning errors, and improves the flexibility, practicality, convenience and applicability of the bracket device, meeting various needs of cable laying in cable trenches, thereby improving the laying efficiency and quality of cables. The locking mechanism not only changes the horizontal angle of the bracket module, but its unobstructed rotation makes the horizontal angle adjustment of the bracket module more flexible and smooth. Workers can precisely adjust the angle of the bracket module according to the actual route of the cable trench, the curvature of the cable, and other specific needs, ensuring that the cable is in the optimal stress state during laying and avoiding excessive stretching or compression of the cable due to angle deviation. It can also quickly lock the bracket module. This locking method generates a strong clamping force, firmly fixing the bracket module to the fixing plate, effectively preventing the bracket module angle from shifting under the action of external forces such as cable weight or environmental vibration. This ensures the stability of cable laying, allowing the cable weight and external forces borne by the bracket module to be stably transmitted to the fixing plate, and then distributed to the surface of the cable trench through the fixing plate. This avoids structural deformation or damage caused by excessive local stress, meeting the usage requirements of different load scenarios.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] like Figures 1 to 11 As shown, an adjustable cable tray device for cable trenches, provided as an embodiment of the present invention, includes a fixing plate 100 directly locked to the surface of the cable trench, a locking mechanism 200 with an adjustable horizontal angle installed on the fixing plate 100, and further includes: The bracket module 300 can be freely increased or decreased according to the actual cable laying requirements. Two adjacent bracket modules 300 are interlocked. The bracket module 300 consists of a bracket plate 400 and an assembly mechanism. The assembly mechanism is installed at the bottom of the bracket plate 400. The bracket plate 400 at the tail end is fixedly connected to the locking mechanism 200. The bracket plate 400 has a groove 410 in the middle and an arc-shaped baffle 420 on one side of the bracket plate 400 at the head end. This can prevent the cable laid on the head bracket plate 400 from falling off, ensuring the cable laying quality and thus improving the support quality of the device for the cable. The assembly mechanism includes a snap-fit ​​component 500 and a snap-fit ​​component 600, which are respectively fixed to the front and rear ends of the bottom of the same bracket plate 400. The snap-fit ​​components 500 and snap-fit ​​components 600 on adjacent bracket plates 400 snap into each other, thereby enabling quick connection of adjacent bracket modules 300. This plug-and-play connection method can effectively shorten the installation time of the bracket module 300, improve the efficiency of bracket device disassembly and modification, and facilitate later maintenance and replacement. When a bracket module 300 is damaged, it can be disassembled and replaced individually without affecting other modules, reducing interference with the overall cable laying system and lowering maintenance costs. Due to the modularity of the bracket plate 400, the number of bracket modules 300 can be freely increased or decreased according to cable laying requirements. This feature breaks the limitations of traditional fixed-length brackets. When the number of cables to be laid is small, only a small number of bracket modules 300 need to be installed to meet the support requirements, which can avoid material waste and reduce the space occupied by the bracket device in the cable trench. If it is necessary to expand or increase the number of cables in the future, the required number of bracket modules 300 can be added adaptively without large-scale modification of the original device structure. This greatly improves the adaptability of the device in different engineering stages, reduces the cost loss caused by early planning errors, and improves the flexibility, practicality, convenience and applicability of the bracket device, meeting various needs of cable laying in cable trenches, thereby improving the laying efficiency and quality of cables.

[0032] In this embodiment, the fixing plate 100 can be equipped with one locking mechanism 200 or multiple locking mechanisms 200. Multiple locking mechanisms 200 can be fixed on the same fixing plate 100 in a stepped manner. The shape, specifications and size of the fixing plate 100 can be adjusted and produced according to actual needs.

[0033] like Figures 3 to 8As shown, in a preferred embodiment of the present invention, the engaging assembly 500 includes a lower mounting plate 510, an upper mounting plate 520, an engaging member 560, a pin 570, and a torsion spring 580. The upper mounting plate 520 and the lower mounting plate 510 are spliced ​​together and secured to the bottom of the bracket plate 400 by the same screw. Engaging cavities 530 are provided in the middle of both the upper mounting plate 520 and the lower mounting plate 510. Releasing cavities 540 are also symmetrically provided on both the upper mounting plate 520 and the lower mounting plate 510. The two releasing cavities 540 are located on both sides of the engaging cavity 530, and the releasing cavities 540 are positioned between the engaging cavity 530 and the locking cavity 530. A connecting slot 550 is provided, and a pin 570 is fixed to the inner wall of the engaging cavity 530 on the lower mounting plate 510. An engaging component 560 is rotatably mounted on the outer side of the pin 570. A torsion spring 580 is provided between the pin 570 and the engaging component 560. The two ends of the torsion spring 580 are respectively connected to the inner wall of the engaging component 560 and the outer wall of the pin 570. One end of the engaging component 560 engages with the engaging assembly 600, and the other end of the engaging component 560 passes through the connecting slot 550 and extends into the release cavity 540. The middle part of the engaging component 560 contacts the inner wall of the engaging cavity 530.

[0034] The engaging component 560 is composed of an engaging sleeve 561, an engaging block 562, a limiting plate 563, and a release plate 564. The engaging sleeve 561 is mounted on a pin 570 and connected to a torsion spring 580. The engaging sleeve 561 is fixed with the engaging block 562, the limiting plate 563, and the release plate 564. The engaging block 562 is located in the engaging cavity 530 and cooperates with the engaging assembly 600. The limiting plate 563 is located in the engaging cavity 530 and contacts the inner wall of the engaging cavity 530. One end of the release plate 564 passes through the connecting groove 550 and extends into the release cavity 540.

[0035] The snap-fit ​​block 562, in conjunction with the torsion spring 580 and the pin 570, can engage with the snap-fit ​​assembly 600 to quickly connect adjacent bracket modules 300. This plug-and-play connection method effectively shortens the installation time of the bracket modules 300, improves the efficiency of bracket device disassembly and modification, and facilitates later maintenance and replacement. When a bracket module 300 is damaged, it can be disassembled and replaced individually without affecting other modules, reducing interference with the overall cable laying system and lowering maintenance costs. The limiting plate 563 is used to control the rotation direction and rotation angle of the locking block 562, thereby improving the connection stability between the locking assembly 600 and the locking block 562, and thus improving the connection stability between adjacent bracket modules 300; the release plate 564 is used to control the rotation of the locking block 562, making it convenient for staff to quickly disassemble the locking block 562 and the locking assembly 600, thereby facilitating the maintenance or replacement of the bracket plate 400 and improving the practicality, convenience and flexibility of the device.

[0036] In a preferred embodiment, the release cavity 540 is used to allow the release column to enter. The release column is preferably a square column, with equidistant paddles distributed on one end face, matching the spacing and number of the multiple release plates 564. When it is necessary to release a release plate 564, the release column is inserted into the release cavity 540, while simultaneously positioning the paddles parallel to the release plate 564. This avoids motion interference between the paddles and the release plate 564 during the process of entering the release cavity 540, i.e., avoids paddle interference. Interfering with the release plate 564, when the release column extends to the designated position, the release column is rotated so that the lever can rotate to the same side as the release plate 564. At this time, the release column is pulled outward, which realizes the lever moving the release plate 564, causing the locking sleeve 561 to rotate and complete the separation from the locking assembly 600. This achieves the rapid separation of the locking assembly 500 and the locking assembly 600, facilitating the maintenance or replacement of the bracket plate 400 and improving the practicality, convenience and flexibility of the device.

[0037] like Figures 3 to 8 As shown, in a preferred embodiment of the present invention, the snap-fit ​​assembly 600 includes a fixing base 610, a snap-fit ​​post 620, and a snap-fit ​​groove 630. The fixing base 610 is fixed to the bottom of the bracket plate 400. A snap-fit ​​post 620 is fixed on one end face of the fixing base 610 near the snap-fit ​​block 562. Snap-fit ​​grooves 630 that cooperate with the snap-fit ​​block 562 are equidistantly provided on both sides of the snap-fit ​​post 620. The spacing between adjacent snap-fit ​​grooves 630 is consistent with that between adjacent snap-fit ​​blocks 562.

[0038] When multiple bracket modules 300 need to be assembled, the snap-fit ​​post 620 is inserted into the release cavity 540 on the adjacent bracket module 300, so that the snap-fit ​​groove 630 on the snap-fit ​​post 620 can fully and effectively cooperate with the snap-fit ​​block 562, thereby completing the quick connection of adjacent bracket modules 300. This plug-and-play connection method can effectively shorten the installation time of the bracket module 300, improve the efficiency of bracket device disassembly and modification, and facilitate later maintenance and replacement. When a bracket module 300 is damaged, it can be disassembled and replaced individually without affecting other modules, reducing interference with the overall cable laying system and reducing maintenance costs.

[0039] In a preferred embodiment, the fixing seat 610 preferably adopts a block structure with a T-shaped cross section, and the middle part of the fixing seat 610 is higher than the side, which facilitates the release column to quickly enter the bottom of the bracket plate 400, thereby completing the quick disassembly of the adjacent bracket module 300. The front end of the snap-fit ​​post 620 is designed as a tapered head 640, which facilitates the snap-fit ​​post 620 to quickly enter the engagement cavity 530 and complete the rapid engagement of the snap-fit ​​post 620 and the engagement block 562.

[0040] like Figures 9 to 11 As shown, in a preferred embodiment of the present invention, the locking mechanism 200 includes a locking component 210 and a connecting component 220. The locking component 210 is mounted on the fixed plate 100. One end of the connecting component 220 is rotatably mounted in the middle of the locking component 210, and the other end of the connecting component 220 is connected to the bracket module 300 at the tail end.

[0041] The locking assembly 210 includes an ear plate 211, a locking stud 212, an upper locking block 213, and a lower locking block 214. The ear plate 211 is vertically fixed on the fixing plate 100. The locking stud 212 is threadedly connected to the ear plate 211. One end of the locking stud 212 is fixed with the upper locking block 213, and the other end of the locking stud 212 is slidably mounted with the lower locking block 214. One end of the connecting assembly 220 is located between the upper locking block 213 and the lower locking block 214 and cooperates with the upper locking block 213 and the lower locking block 214 respectively.

[0042] Initially, the upper locking block 213 and the lower locking block 214 are not tightly engaged with the connecting component 220. At this time, the connecting component 220 can rotate freely around the locking stud 212, thereby changing the horizontal angle of the bracket module 300. This unobstructed rotation characteristic makes the horizontal angle adjustment of the bracket module 300 more flexible and smooth. According to the actual route of the cable trench, the curvature of the cable, and other specific needs, the staff can accurately adjust the angle of the bracket module 300 to ensure that the cable is in the best stress state during laying and avoid excessive stretching or compression of the cable due to angle deviation. When the bracket module 300 rotates to the specified horizontal angle, the locking stud 212 rotates and drives the upper locking block 213 to move downward. The upper locking block 213 can quickly lock the connecting component 220 by moving downward and cooperating with the lower locking block 214. This locking method can form a strong clamping force, firmly fixing the connecting component 220 between the upper locking block 213 and the lower locking block 214. This effectively prevents the bracket module 300 from shifting its angle under the action of external forces such as cable weight or environmental vibration, ensuring the stability of cable laying. This allows the cable weight and external force borne by the bracket module 300 to be stably transmitted to the fixing plate 100, and then distributed to the surface of the cable trench by the fixing plate 100. This avoids structural deformation or damage caused by excessive local stress and meets the usage requirements of different load scenarios.

[0043] like Figures 9 to 11 As shown, in a preferred embodiment of the present invention, the connecting assembly 220 includes a locking sleeve 221, a clamping plate 222, a locking groove 223, an annular plate 224, and a locking spring 225. The locking sleeve 221 is located outside the locking stud 212 and between the upper locking block 213 and the lower locking block 214. The clamping plate 222, which is fixedly connected to the tail end bracket module 300, is fixed on the outer wall of the locking sleeve 221. Locking grooves 223 are provided on the inner walls of both the upper and lower ends of the locking sleeve 221. The two locking grooves 223 cooperate with the upper locking block 213 and the lower locking block 214, respectively. An annular plate 224 is fixed in the middle of the inner wall of the locking sleeve 221. The annular plate 224 is connected to the lower locking block 214 through the locking spring 225.

[0044] The locking groove 223 is preferably a frustum-shaped groove, and the upper locking block 213 and the lower locking block 214 are preferably frustum-shaped block structures.

[0045] In the initial state, the locking spring 225 can drive the locking sleeve 221 to separate from the lower locking block 214 through its own elastic force, so that the locking sleeve 221 can rotate freely, thereby enabling the staff to accurately adjust the angle of the bracket module 300 according to the actual route of the cable trench, the curvature of the cable and other specific needs. When the upper locking block 213 moves downward, it drives the locking sleeve 221 to move downward, so that the locking grooves 223 at both ends of the locking sleeve 221 can fully and tightly fit with the upper locking block 213 and the lower locking block 214, thereby completing the rapid locking of the connecting component 220. This locking method can form a strong clamping force, firmly fixing the connecting component 220 between the upper locking block 213 and the lower locking block 214, effectively preventing the bracket module 300 from shifting its angle under the action of external forces such as cable self-weight or environmental vibration, ensuring the stability of cable laying, so that the cable weight and external force borne by the bracket module 300 can be stably transmitted to the fixing plate 100, and then distributed to the surface of the cable trench through the fixing plate 100, avoiding structural deformation or damage caused by excessive local stress, and meeting the usage requirements of different load scenarios.

[0046] The working principle of this invention is: The snap-fit ​​block 562, in conjunction with the torsion spring 580 and the pin 570, can engage with the snap-fit ​​assembly 600 to quickly connect adjacent bracket modules 300. This plug-and-play connection method effectively shortens the installation time of the bracket modules 300, improves the efficiency of bracket device disassembly and modification, and facilitates later maintenance and replacement. When a bracket module 300 is damaged, it can be disassembled and replaced individually without affecting other modules, reducing interference with the overall cable laying system and lowering maintenance costs. The limiting plate 563 is used to control the rotation direction and rotation angle of the locking block 562, thereby improving the connection stability between the locking assembly 600 and the locking block 562, and thus improving the connection stability between adjacent bracket modules 300; the release plate 564 is used to control the rotation of the locking block 562, making it convenient for staff to quickly disassemble the locking block 562 and the locking assembly 600, thereby facilitating the maintenance or replacement of the bracket plate 400 and improving the practicality, convenience and flexibility of the device; Due to the modularity of the bracket plate 400, the number of bracket modules 300 can be freely increased or decreased according to the cable laying requirements. This feature breaks the limitations of traditional fixed-length brackets. When the number of cables to be laid is small, only a small number of bracket modules 300 need to be installed to meet the support requirements. This avoids material waste and reduces the space occupied by the bracket device in the cable trench. If it is necessary to expand the capacity or increase the number of cables in the future, the required number of bracket modules 300 can be added adaptively without large-scale modification of the original device structure. This greatly improves the adaptability of the device in different engineering stages, reduces the cost loss caused by early planning errors, and improves the flexibility, practicality, convenience and applicability of the bracket device. In the initial state, the locking spring 225 can drive the locking sleeve 221 to separate from the lower locking block 214 through its own elastic force, so that the locking sleeve 221 can rotate freely, thereby enabling the staff to accurately adjust the angle of the bracket module 300 according to the actual route of the cable trench, the curvature of the cable and other specific needs. When the upper locking block 213 moves down, it drives the locking sleeve 221 to move down, so that the locking grooves 223 at both ends of the locking sleeve 221 can fully and tightly fit with the upper locking block 213 and the lower locking block 214, thereby completing the rapid locking of the connecting component 220. This locking method can form a strong clamping force, firmly fixing the connecting component 220 between the upper locking block 213 and the lower locking block 214, effectively preventing the bracket module 300 from shifting its angle under the action of external forces such as cable self-weight or environmental vibration, ensuring the stability of cable laying, so that the cable weight and external force borne by the bracket module 300 can be stably transmitted to the fixing plate 100, and then distributed to the surface of the cable trench through the fixing plate 100, avoiding structural deformation or damage caused by excessive local stress, and meeting the usage requirements of different load scenarios; The above describes the working principle of the adjustable cable tray device for the cable trench.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
