It includes a cable tray body, with guardrails installed at the center of both the front and rear ends of the top of the cable tray body. Adjustment frames are provided at both the left and right ends of the top of the cable tray body. A first adjusting screw is installed at the bottom of the adjustment frame, penetrating the bottom of the cable tray body. A first locking nut is fitted around the first adjusting screw. From the inside to the outside, sliding grooves and baffles are sequentially provided at the front and rear ends of the top of the adjustment frame. The overall device has a simple structure, is convenient for adjusting the angle according to the needs of cable laying, and can adapt to different cable laying requirements. It also facilitates heat dissipation and cable protection, and has high stability and practicality, making it worthy of widespread application.

[0003] In the prior art, including the aforementioned patents, traditional cable trays typically employ simple trough or frame structures. During cable laying, workers must manually pull the cables through the tray. This method is extremely time-consuming and labor-intensive, especially when dealing with large numbers of cables and complex wiring. For example, in cable laying projects in large commercial complexes or data centers, workers often spend weeks or even months pulling cables. Furthermore, manual pulling easily leads to cables becoming tangled and twisted, increasing the risk of damage during laying and making it difficult to ensure neatness and standardization. Therefore, a cable tray with a lead-in structure is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray with a lead wire structure for cable laying, so as to solve the problems of conductor assembly and lead wire structure mentioned in the background art, realize automatic cable guidance and laying, improve cable laying efficiency, and reduce manual labor intensity and safety risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable tray with a lead wire structure for cable laying, comprising a cable trough, a protective frame fitted to the top of the cable trough, an installation rail fitted to the outer wall of the cable trough, a support rod fixedly connected to the bottom of the installation rail, a mounting base fixedly connected to one end of the support rod, a wire assembly fixedly connected to the top end of the protective frame, a drive cylinder mounted on the top of the protective frame, and a lead wire assembly mounted on the output end of the drive cylinder.

[0006] Furthermore, the conductor assembly includes a connecting frame, a triangular support frame, a drive wheel, and a driven wheel. The connecting frame is fixedly connected to one end of the top of the protective frame, and the triangular support frame is fixedly connected to one end of the connecting frame. The drive wheel is connected to the internal bearing of the triangular support frame, and the driven wheel is connected to the inner wall bearing of the triangular support frame.

[0007] Furthermore, the driven wheels are configured in two sets, with the driven wheels located below the drive wheels.

[0008] Furthermore, the lead assembly includes an electric rotating disk, an electric telescopic rod, a clamping arm, and a tension spring. The output end of the drive cylinder is fixedly connected to the electric rotating disk, the output end of the electric rotating disk is equipped with an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to a clamping arm, and the inner wall of the clamping arm is fixedly connected to a tension spring.

[0009] Furthermore, an angle sensor is provided at the output end of the electric rotary disk, and the angle sensor is electrically connected to the control end of the electric rotary disk.

[0010] Furthermore, the inner wall of the clamping arm is provided with an anti-slip rubber layer, the surface of which is provided with cross-shaped anti-slip texture, and the anti-slip rubber layer is fixedly connected to the tension spring.

[0011] Furthermore, the outer wall of the mounting rail is provided with evenly distributed threaded holes, and the outer wall of the wire groove is provided with fixing bolts that are compatible with the threaded holes. Through the cooperation of the fixing bolts and the threaded holes, a stable fitting connection between the mounting rail and the wire groove is achieved.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the cable tray with lead wire structure for cable laying is reasonable and has the following advantages:

[0013] (1) Through the coordinated operation of the conductor assembly and the lead assembly, the cable can be automatically guided and laid in the cable tray. In this process, there is no need for manual pulling of the cable, which greatly improves the efficiency of cable laying. The electric rotary table, electric telescopic rod and clamping arm work together to form a highly flexible adjustment system. When facing complex and ever-changing cable laying paths, the electric rotary table can achieve a smooth rotation and accurately adjust the orientation of the lead assembly; the electric telescopic rod can freely extend and retract within a certain range according to actual needs, flexibly changing the horizontal or vertical position of the lead assembly; the clamping arm can firmly clamp the cable and, in conjunction with the actions of the first two, make fine adjustments to the angle of the lead assembly. Through the coordinated operation of these three, the position and angle of the lead assembly can be flexibly adjusted according to different cable laying path requirements to ensure that the cable is accurately laid to the predetermined position, effectively avoiding problems such as cable tangling and chaotic laying, and greatly improving the efficiency and quality of cable laying.

[0014] (2) The cable tray adopts a carefully designed structure. Through the clever combination of closely arranged protective railings and waterproof and dustproof materials, it can effectively block the corrosion of external debris on the cable, thereby effectively protecting the cable insulation layer and internal structure and preventing failure caused by scratches from external objects. The design of components such as cable trays and mounting rails fully considers mechanical principles. The cable trays are made of high-strength metal materials and have undergone special thickening treatment, which has excellent pressure resistance. The mounting rails are closely matched with the cable trays through precise size design and stable connection. The two complement each other and greatly enhance the overall structural strength of the cable tray, enabling it to withstand a certain degree of external impact and providing a stable and safe laying environment for the cable. At the same time, the electric telescopic rod in the lead assembly can adjust the telescopic length according to the length of the cable and the laying requirements. The electric rotating disk can flexibly change the direction of the lead wire. Meanwhile, the support rod is a telescopic structure and can adjust the length according to the actual installation environment, making the cable tray suitable for a variety of complex cable laying scenarios and improving the versatility and adaptability of the cable tray.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A cable tray with a lead wire structure for cable laying includes a cable trough 1, a protective frame 2 fitted to the top of the cable trough 1, an installation rail 3 fitted to the outer wall of the cable trough 1, a support rod 4 fixedly connected to the bottom of the installation rail 3, a mounting base 5 fixedly connected to one end of the support rod 4, a wire assembly 6 fixedly connected to one end of the top of the protective frame 2, a drive cylinder 7 installed on the top of the protective frame 2, and a lead wire assembly 8 installed at the output end of the drive cylinder 7.

[0025] The above structure, based on the location and environment of the cable laying, fixes the mounting base 5 in a suitable position by adjusting the telescopic length of the support rod 4, ensuring the cable tray is installed stably.

[0026] Furthermore, the conductor assembly 6 includes a connecting frame 601, a triangular support frame 602, a drive wheel 603, and a driven wheel 604 inside. The connecting frame 601 is fixedly connected to one end of the top of the protective frame 2, and the triangular support frame 602 is fixedly connected to one end of the connecting frame 601. The drive wheel 603 is connected to the internal bearing of the triangular support frame 602, and the driven wheel 604 is connected to the inner wall bearing of the triangular support frame 602. The driven wheel 604 is configured in two sets, and the driven wheel 604 is located below the drive wheel 603.

[0027] The above structure involves placing one end of the cable between the drive wheel 603 and the driven wheel 604 of the conductor assembly 6, activating the servo motor of the drive wheel 603, and causing the drive wheel 603 to rotate and drive the cable forward.

[0028] Furthermore, the lead assembly 8 includes an electric rotating disk 801, an electric telescopic rod 802, a clamping arm 803, and a tension spring 804. The output end of the drive cylinder 7 is fixedly connected to the electric rotating disk 801. The output end of the electric rotating disk 801 is equipped with the electric telescopic rod 802. The output end of the electric telescopic rod 802 is fixedly connected to the clamping arm 803. The inner wall of the clamping arm 803 is fixedly connected to the tension spring 804. The output end of the electric rotating disk 801 is equipped with an angle sensor, which is electrically connected to the control end of the electric rotating disk 801. The inner wall of the clamping arm 803 is provided with an anti-slip rubber layer. The surface of the anti-slip rubber layer has cross-shaped anti-slip patterns, and the anti-slip rubber layer is fixedly connected to the tension spring 804.

[0029] According to the cable laying path, the above structure uses an external control system to control the drive cylinder 7 to move the lead wire assembly 8, the electric rotary table 801 to adjust its angle, and the electric telescopic rod 802 to extend, bringing the clamping arm 803 closer to the cable. The tension spring 804 then elastically deforms and clamps the cable. Finally, the drive cylinder 7 moves the lead wire assembly 8, pulling the cable into the cable tray 1, completing the cable laying process.

[0030] Furthermore, the outer wall of the mounting rail 3 is provided with evenly distributed threaded holes, and the outer wall of the wire groove 1 is provided with fixing bolts that are compatible with the threaded holes. Through the cooperation of the fixing bolts and the threaded holes, the mounting rail 3 and the wire groove 1 are stably fitted and connected.

[0031] Working principle: In use, the cable is first carefully placed between the drive wheel 603 and the driven wheel 604 of the conductor assembly 6. The drive wheel 603 is driven by a high-performance servo motor with precise speed control, ensuring stable rotation of the drive wheel 603, thereby driving the cable forward smoothly and at a uniform speed. During cable transport, the drive cylinder 7 is quickly activated, using its powerful thrust to push the lead assembly 8 along the preset track to the appropriate position for cable laying.

[0032] Secondly, the electric rotary table 801 begins operation. Based on the pre-planned cable laying path requirements, it quickly and accurately adjusts its angle using a built-in high-precision angle sensor and intelligent control system. Next, the electric telescopic rod 802 gradually extends under the control system's command, causing the clamping arm 803 to slowly approach the cable. The tension spring 804 installed on the inner wall of the clamping arm 803 plays a crucial role; its excellent elastic coefficient provides just the right amount of elastic clamping force, thus firmly and reliably clamping the cable.

[0033] Finally, the drive cylinder 7 exerts force again, driving the lead wire assembly 8 to move as a whole. During this process, the clamped cable is accurately laid into the cable tray 1 according to the predetermined path under the traction of the lead wire assembly 8. In addition, the protective frame 2 is ingeniously designed to effectively prevent external debris, such as dust and stones, from falling into the cable tray 1, avoiding damage such as scratches and corrosion to the cable, and providing comprehensive protection for the cable. The mounting rail 3, support rod 4, and mounting base 5 work together to form a stable support structure. Through scientific and reasonable mechanical design, it ensures that the cable tray can be stably installed in various complex environments, ensuring the smooth progress of cable laying.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
