Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to an automated cable laying device for cable trays. Background Technology

[0002] Cable trays are metal or non-metal structural systems used to support and protect cables and optical fibers. They are widely used in the laying of power and communication lines in fields such as construction, industry, and data centers. In power and communication engineering construction, cable trays are widely used as an important carrier for cable laying. However, the laying of cables within cable trays requires efficient and flexible wiring methods, suitable for the centralized laying of various types of cables, including power, communication, and control cables.

[0003] Traditional cable tray installation methods largely rely on manual operation, requiring operators to handle, lay, and organize cables on the trays. This method presents several problems. First, manual installation is inefficient, especially in large-scale projects where the extensive cable laying requires significant manpower and time. Second, manual operation carries high safety risks, with operators prone to falls from heights while working on the trays. Furthermore, it's difficult to ensure consistency in cable arrangement and tension during manual installation, affecting the quality of the installation and its future use. While some auxiliary cable laying devices have emerged, most are complex in structure, inconvenient to operate, and cannot effectively adapt to different specifications and shapes of cable trays, failing to meet the diverse needs of practical projects. Therefore, there is an urgent need for an efficient, safe, and highly adaptable automated cable tray installation device. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an automated cable laying device for cable trays. Cable laying is completed by a cable laying trolley traveling on the cable tray. The drive wheels and driven wheels of the cable laying trolley are adjusted according to the width of the cable tray to accommodate different cable trays. Cable laying trolleys are set up in the straight and turning sections of the cable tray. The cable traction mechanism of the cable laying trolley pulls the cable to lay in the cable tray, which improves the efficiency of cable laying, makes the cables neatly arranged, improves the quality of cable laying, and reduces the intensity of manual labor and safety risks.

The cable is laid in the straight section of the cable tray 8. The cable traction trolley 1 arranges the cable to the turning point of the cable tray 8. The traction motor 6-4 of the cable traction trolley 1 at the turning point rotates to drive the cable forward. The pneumatic gripper 6-3 at the turning point guides the cable in an arc and lays it at the turning point of the cable tray 8. Then, the next section of cable is laid by the next section of the cable traction trolley 1 until the cable laying is completed.

[0031] like Figures 1-12 As shown, an automated cable laying device for cable trays includes a cable laying frame 3, a cable conveyor 2, and a cable laying trolley 1. The cables on the cable laying frame 3 are conveyed by the cable conveyor 2. The cable laying trolley 1 is installed on the cable tray 8 where the cables are arranged.
