Description

Technical Field

[0001] This invention belongs to the field of cable tray technology, and specifically relates to a quick-installation cable tray that facilitates cable laying. Background Technology

[0002] Cable trays are structural systems used to support, protect, and manage cables. They mainly consist of tray supports, brackets, and installation accessories (such as straight sections, bends, tees, and crosses). With rigid structural characteristics, they are key supporting equipment for cable laying. Their functions encompass multiple core dimensions, including supporting cables, isolating external interference, orderly arranging lines, and improving heat dissipation. Through fully enclosed (such as trough-type cable trays) or semi-enclosed (such as tray-type cable trays) structures, they isolate cables from direct contact with the external environment, preventing damage from sunlight exposure, fog and humidity, rain erosion, and mechanical collisions (such as scratches from equipment in industrial plants), thus extending the cable's service life.

[0003] In current building electrical and industrial facility wiring projects, cable trays, as the core carrier for supporting and protecting cables, are widely used. However, their traditional design has gradually revealed significant limitations in actual operation. On the one hand, existing cable trays generally adopt a combination of fixed-size straight sections and standard bends. Cables can only be rigidly arranged along a preset path during installation. If there are adjustments to equipment layout, changes in functional areas, or subsequent expansion needs, cables need to be repeatedly twisted and crossed in the narrow space of the cable tray. This not only makes it difficult to achieve orderly "layered and classified" cable management, but also easily leads to reduced heat dissipation efficiency, insulation wear, and even increased risk of short circuits due to tangling. Traditional cable trays cannot flexibly adapt to dynamic wiring needs, often requiring additional manual sorting, which greatly increases construction complexity and maintenance costs. On the other hand, the standardized bends of traditional cable trays cannot match these differentiated needs. Forced installation can easily lead to conductor breakage and sheath damage in cables, directly affecting line life and transmission reliability. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-installation cable tray that facilitates cable laying, thereby solving the problems mentioned in the background art where existing cable trays are inconvenient for cable management and laying, and where cables are inconvenient for bending and laying.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-installation cable tray for easy cable laying includes:

[0007] Cable tray base;

[0008] The mounting mechanism is located outside the cable tray base;

[0009] A rotating mechanism is installed on the outside of the cable tray base. The rotating mechanism includes a mounting plate, and a plurality of first rotating shafts are provided at the top of the mounting plate. Each of the plurality of first rotating shafts is fixedly connected to a fixed seat at its top.

[0010] A clamping mechanism is provided at the top of a rotating mechanism. The clamping mechanism includes a mounting frame, a telescopic rod is inserted inside the mounting frame, a first telescopic spring is sleeved on the outside of the telescopic rod, a clamping plate is fixedly connected to one side of the telescopic rod, a second telescopic spring is inserted at the top of the mounting frame, and an abutment telescopic seat is fixedly connected to the bottom end of the second telescopic spring.

[0011] Preferably, the fixing seat is rotatably connected to the top end of the first rotating shaft, and multiple first rotating shafts are horizontally arranged at the top end of the mounting plate, and a clamping mechanism is installed at the top end of the fixing seat.

[0012] Preferably, the telescopic rod is elastically telescopically connected to the first telescopic spring, the clamping plate has a semi-circular structure, one side of the first telescopic spring is fixedly connected to the inside of the mounting frame, and two clamping plates are symmetrically arranged.

[0013] Preferably, the abutting telescopic seat is elastically telescopically connected to the second telescopic spring, and two sliding limit rods are fixedly installed at the top of the abutting telescopic seat.

[0014] Preferably, a movable mechanism is installed on the outside of one side of the rotating mechanism, and a rolling mechanism is provided inside the clamping mechanism.

[0015] Preferably, the installation mechanism includes a limiting plate, a limiting insert plate is inserted inside the limiting plate, a splitter frame is fixedly connected to one side of the limiting insert plate, the limiting insert plates are symmetrically arranged on both sides of the splitter frame, and the splitter frame is installed inside the limiting plate through the limiting insert plates.

[0016] Preferably, the movable mechanism includes a mounting base, a bearing seat is mounted on the top of the mounting base, a second rotating shaft is fixedly connected to the inner ring of the bearing seat, and a connecting plate is fixedly connected to the outside of the second rotating shaft.

[0017] Preferably, the second rotating shaft is rotatably connected to the bearing housing, one side of the connecting plate is fixedly connected to the outside of one side of the mounting plate, and the bottom end of the mounting base is fixedly connected to the top end of the cable tray base.

[0018] Preferably, the rolling mechanism includes a connecting shaft seat, a first roller plate is fixedly connected to one side of the connecting shaft seat, a second roller plate is fixedly connected to one side of the first roller plate, a plurality of first rollers are provided on the outside of the first roller plate, and a plurality of second rollers are provided on the outside of the second roller plate.

[0019] Preferably, the first rolling wheel and the second rolling wheel are respectively disposed outside the first roller plate and the second roller plate, and the first rolling wheel and the second rolling wheel are rotatably connected outside the first roller plate and the second roller plate, respectively. Both the first rolling wheel and the second rolling wheel are rubber wheels with a rough structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) The present invention, through the installation frame, telescopic rod, first telescopic spring and clamping plate, enables the structure to achieve precise positioning and adaptive adjustment through a dual elastic clamping mechanism after the cable is inserted into the installation frame. First, the abutting telescopic seat and the second telescopic spring form a vertical elastic buffer system. Through the compression and rebound characteristics of the spring, the height position of the abutting telescopic seat can be intelligently adjusted to ensure stable fit of cables with different outer diameters in the vertical direction. At the same time, the horizontal clamping unit composed of the telescopic rod and the first telescopic spring adapts to the size of cables with different inner diameters through elastic deformation. The automatic adjustment of clamping force ensures stable positioning of cables of various specifications while avoiding excessive compression that could damage the cable insulation layer. This prevents displacement due to gravity or external forces during installation. When cable stretching or dragging is required, the built-in rolling mechanism provides dynamic support through the coordinated rotation of the first and second rolling wheels. These wheels are oriented in the same direction, maintaining close contact with the cable's outer surface while keeping friction low. As the cable moves under tension, the rolling wheels rotate accordingly, converting the sliding friction between the cable and the mounting bracket into rolling friction, significantly reducing dragging resistance. This design not only makes the cable stretching process smoother and more efficient, reducing manual force application, but also avoids problems such as wear on the cable's outer sheath and scratches on the internal conductors caused by friction, further enhancing the safety of cable laying and the functionality of the cable tray system.

[0022] (2) The present invention enables the fixed seat structure to rotate flexibly outside the first rotating shaft by setting the mounting plate, the first rotating shaft, the limiting plate and the limiting insert plate. It can not only accurately control the deflection angle of the clamping mechanism, but also adjust the bending direction of the cable according to the actual construction needs. When encountering special working conditions that require bending and laying, the operator can easily adjust the angle of the fixed seat so that the cable can naturally transition to the predetermined path, effectively avoiding the stress concentration problem caused by the rigid fixing of the cable in the traditional installation method. The mounting plate, in conjunction with the cable tray, forms a linkage mechanism with the second rotating shaft via a connecting plate. This dual-rotation design enables the entire clamping mechanism to achieve multi-directional adjustment and vertical angle adjustment. It can accurately position the cable laying direction and ensure a smooth transition arc at the corner of the distribution frame. Through mechanical optimization design, this structure disperses the stress that was originally concentrated at the narrow corner between the distribution frame and the cable tray seat to a larger stress surface. This significantly improves the ease of operation of the cable tray system and effectively prevents quality hazards such as insulation layer cracking and conductor breakage by reducing plastic deformation caused by excessively small cable bending radius. It is particularly suitable for application scenarios with high requirements for cable protection, such as data centers and intelligent buildings. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figures 1-6 As shown, a quick-installation cable tray for easy cable laying includes:

[0033] Cable tray seat 1;

[0034] Mounting mechanism 2, which is disposed outside the cable tray base 1;

[0035] Rotation mechanism 3 is installed on the outside of cable tray seat 1. Rotation mechanism 3 includes mounting plate 301. The top end of mounting plate 301 is provided with a plurality of first rotation shafts 302. The top end of the plurality of first rotation shafts 302 is fixedly connected to a fixing seat 303.

[0036] A clamping mechanism 4 is disposed at the top of the rotating mechanism 3. The clamping mechanism 4 includes a mounting frame 401, a telescopic rod 402 inserted inside the mounting frame 401, a first telescopic spring 403 sleeved on the outside of the telescopic rod 402, a clamping plate 404 fixedly connected to one side of the telescopic rod 402, a second telescopic spring 405 inserted at the top of the mounting frame 401, and an abutment telescopic seat 406 fixedly connected to the bottom end of the second telescopic spring 405. The fixed seat 303 is rotatably connected to the top of the first rotating shaft 302. The first rotating shaft 302 is horizontally arranged in multiple positions at the top of the mounting plate 301. The top of the fixed seat 303 is equipped with a clamping mechanism 4. The telescopic rod 402 is elastically telescopically connected to the first telescopic spring 403. The clamping plate 404 has a semi-circular structure. One side of the first telescopic spring 403 is fixedly connected to the inside of the mounting frame 401. Two clamping plates 404 are symmetrically arranged. The abutting telescopic seat 406 is elastically telescopically connected to the second telescopic spring 405. Two sliding limit rods are fixedly installed at the top of the abutting telescopic seat 406.

[0037] Specifically, the telescopic rod 402 and the first telescopic spring 403 are connected by elastic telescopic connection, which can drive the clamping plate 404 to perform flexible radial telescopic adjustment. This adaptive structure can automatically adjust the clamping range according to the inner diameter of different cables, ensuring that cables of various specifications can be firmly clamped. At the same time, the vertical elastic adjustment system composed of the abutment telescopic seat 406 and the second telescopic spring 405 can precisely control the height position change of the abutment telescopic seat 406, effectively cooperating with the clamping plate 404 to complete the diameter expansion action after inner diameter adjustment, providing balanced support for cables of different diameters. On this basis, the fixed seat 303 can achieve independent rotation adjustment on the first rotating shaft 302, so that each clamping mechanism 4 has an individual angle adjustment function, which can precisely control the spatial posture of each clamping point according to the cable routing requirements. This distributed adjustment mechanism not only enhances the adaptability of the cable tray system to complex wiring paths, but also realizes personalized positioning and stable clamping of each cable.

[0038] As can be seen from the above, after the cable is inserted into the mounting bracket 401, the height of the telescopic seat 406 can be flexibly adjusted through the elastic telescopic cooperation between the telescopic seat 406 and the second telescopic spring 405. This height-adjustable design can adapt to the needs of different installation scenarios. At the same time, the elastic clamping system formed by the telescopic rod 402 and the first telescopic spring 403 can adapt to cables of different inner diameters through its adjustable clamping force. Whether the cable is of a large or small diameter, it can achieve a stable limiting clamping, ensuring that the cable is accurately fixed in position when laid in the cable tray, effectively preventing the cable from shifting or loosening. When it is necessary to stretch and drag the cable, the rolling mechanism 6 set in the mechanism will tightly abut against the outside of the cable. The first rolling wheel 604 and the second rolling wheel 605 can significantly reduce the frictional resistance between the cable and the cable tray through smooth rotational movement. This not only makes the cable dragging process more effortless and smooth, but also effectively protects the cable sheath from wear, thereby comprehensively improving the functionality and ease of operation of the cable tray in the installation, laying and subsequent maintenance process.

[0039] refer to Figure 2 and Figure 6 As shown, a movable mechanism 5 is installed on the outside of one side of the rotating mechanism 3, a rolling mechanism 6 is provided inside the clamping mechanism 4, the mounting mechanism 2 includes a limiting plate 201, a limiting insert plate 202 is inserted inside the limiting plate 201, a branch frame 203 is fixedly connected to one side of the limiting insert plate 202, the limiting insert plates 202 are symmetrically arranged on both sides of the branch frame 203, the branch frame 203 is installed inside the limiting plate 201 through the limiting insert plate 202, the movable mechanism 5 includes a mounting base 501, a bearing seat 502 is installed at the top of the mounting base 501, a second rotating shaft 503 is fixedly connected to the inner ring of the bearing seat 502, a connecting plate 504 is fixedly connected to the outside of the second rotating shaft 503, the second rotating shaft 503 is rotatably connected to the bearing seat 502, one side of the connecting plate 504 is fixedly connected to the outside of one side of the mounting plate 301, and the bottom end of the mounting base 501 is fixedly connected to the top end of the cable tray base 1.

[0040] Specifically, the flexible rotation of the second rotating shaft 503 on the bearing seat 502 can precisely drive the connected connecting plate 504 to perform multi-angle rotation adjustment. Since the connecting plate 504 is rigidly connected to the mounting plate 301, this rotation will synchronously drive the mounting plate 301 and the clamping mechanism 4 fixed on it to rotate in coordination. When the cable needs to be laid in a turning position in the cable tray system (especially when passing through the transition area between the branch frame 203 and the cable tray seat 1), this adjustment mechanism allows the operator to actively adjust the spatial orientation of the clamping mechanism 4 according to the actual path requirements, so that the cable can transition naturally along the preset smooth curve, rather than being concentrated and squeezed at the right-angle corner between the branch frame 203 and the cable tray seat 1. Through this dynamic position limit adjustment, it not only avoids the accumulation and congestion of multiple cables in the narrow corner area, but also effectively controls the stress concentration problem when the cable is bent, preventing the conductor from being damaged or the insulation layer from cracking due to excessive bending. Ultimately, it significantly improves the operational flexibility and cable protection performance of the cable tray in complex laying scenarios, while reducing the difficulty of later maintenance caused by improper installation.

[0041] Example 2:

[0042] refer to Figures 1-6 As shown, the rolling mechanism 6 includes a connecting shaft seat 601. A first roller plate 602 is fixedly connected to one side of the connecting shaft seat 601, and a second roller plate 603 is fixedly connected to one side of the first roller plate 602. A plurality of first rollers 604 are disposed on the outside of the first roller plate 602, and a plurality of second rollers 605 are disposed on the outside of the second roller plate 603. The first rollers 604 and the second rollers 605 are respectively disposed on the outside of the first roller plate 602 and the second roller plate 603, and the first rollers 604 and the second rollers 605 are rotatably connected on the outside of the first roller plate 602 and the second roller plate 603, respectively. The first rollers 604 and the second rollers 605 are both rubber wheels with a rough structure.

[0043] Specifically, both the first rolling wheel 604 and the second rolling wheel 605 can rotate freely outside the first rolling plate 602. When the first rolling plate 602 is in close contact with the cable surface, these two precisely designed rotating components can significantly reduce the frictional resistance between the cable and the cable tray contact surface through their smooth rotation characteristics. The rolling assistance mechanism allows construction personnel to achieve smooth cable displacement with only a small pulling force when dragging the cable after laying it, greatly improving the movement efficiency of the cable in the cable tray system. Especially in long-distance laying or dense wiring scenarios, this design not only effectively reduces the labor intensity of operators, but also avoids wear of the cable insulation layer and potential damage to the conductor structure by reducing the relative slippage between the cable outer sheath and rigid components. Thus, while ensuring the integrity of the cable, it significantly improves the ease of operation and construction efficiency of the cable tray system in practical engineering applications.

[0044] As can be seen from the above, the fixed seat 303 can rotate flexibly outside the first rotating shaft 302. This design enables precise control and multi-directional adjustment of the deflection angle of the clamping mechanism 4. When encountering special working conditions where cables need to be laid along a specific path, the operator can adjust the tilt angle of the fixed seat 303 to allow the cable to naturally transition to the required direction, avoiding abrupt turns. At the same time, the mounting plate 301, through the composite rotation structure formed by the connecting plate 504 and the second rotating shaft 503, not only supports the overall orientation adjustment of the clamping mechanism 4 in the horizontal plane, but also enables the adjustment of the pitch angle in the vertical plane. This three-dimensional position adjustment function is particularly suitable for the scenario of laying cables at the bend of the junction box 203 node. By fine-tuning the spatial posture of the clamping mechanism 4, the cable can be guided to be evenly distributed and transition along the arc surface of the junction box, effectively preventing multiple cables from crowding and stacking at the right-angle bend between the junction box 203 and the cable tray seat 1. This innovative dual-rotation adjustment mechanism not only significantly improves the ease of operation of cable trays when laying cables in complex paths, but also ensures the uniform stress on conductor materials by optimizing the cable bending radius. This fundamentally avoids quality problems such as insulation layer cracking and conductor breakage caused by forced bending in traditional cable trays, significantly extending the service life of cables and reducing subsequent maintenance costs.
