Description

Technical Field

[0001] This utility model belongs to the field of cable tray laying technology, specifically relating to an auxiliary device for cable tray laying. Background Technology

[0002] Currently, there is no simple construction method for laying low-voltage power cables at bends in cable trays. The work is mostly done manually, resulting in low efficiency, high labor costs, and the risk of damaging the cable sheath or even the cable tray itself. Furthermore, the commonly used single pulley system for fixing to the ceiling can damage the ceiling, forcing rework by the renovation team, and may also pose safety hazards due to the instability of the fixing method.

[0003] Existing technologies are time-consuming and labor-intensive in the long-distance cable tray laying process. Furthermore, cable derailment during the traction process leads to meaningless rework and troubleshooting, which increases manpower input, thereby increasing labor costs and delaying the construction progress. Utility Model Content

[0004] This utility model provides an auxiliary device for cable tray laying, which solves the problems of easy damage to cables and unstable fixation during cable tray laying, resulting in low construction efficiency in the prior art.

[0005] This utility model provides an auxiliary device for laying cable trays, including multiple auxiliary units; each auxiliary unit includes a pulley, a frame and a magnet, the pulley is installed on the top of the frame and is rotatably connected to the frame through a rotating shaft, and the adjacent corners of each frame are hinged to each other;

[0006] Magnets are installed at the bottom of the frame to fix the cable tray laying auxiliary device to the cable tray.

[0007] Compared with the prior art, the advantages of this utility model are as follows: The cable tray laying auxiliary device provided by this utility model adopts the magnetic adsorption mode, which changes the traditional pulley fixing method. It is especially suitable for cable tray corners, bridging and other positions where the cable direction needs to be changed. The pulley protects the cable, and the magnet makes the bottom of the device fit tightly against the cable tray. It is easy to install, saves labor costs and improves construction efficiency.

[0008] Furthermore, a distance measuring device is also provided on the upper surface of the corner of the frame to detect whether the cable is located on the pulley.

[0009] Furthermore, it also includes BLE Bluetooth, which connects to the ranging device.

[0010] Furthermore, the magnet is a neodymium iron boron magnet.

[0011] Furthermore, there are three auxiliary units. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figures 1-3 This utility model provides a cable tray laying auxiliary device, including multiple auxiliary units; each auxiliary unit includes a pulley 1, a frame 2 and a magnet 3. The pulley 1 is installed on the top of the frame 2 and is rotatably connected to the frame 2 through a rotating shaft. The adjacent corners of each frame 2 are hinged to each other; the magnet 3 is installed at the bottom of the frame 2 and is used to fix the cable tray laying auxiliary device on the cable tray.

[0019] The cable tray laying auxiliary device provided by this utility model adopts the adsorption mode of magnet 3, which changes the traditional fixing method of pulley 1. It is especially suitable for cable tray corners, bridging and other positions where the direction of cable needs to be changed. The pulley 1 protects the cable, and the magnet 3 makes the bottom of the device fit tightly against the cable tray. It is easy to install, saves labor costs and improves construction efficiency.

[0020] Furthermore, a distance measuring device 4 is also installed on the upper surface of the corner of the frame 2 to detect whether the cable is located on the pulley 1. It is understandable that power cables are prone to derailment during the traction process when laying long-distance cable trays. Therefore, by installing a distance measuring device 4 on the corner of the frame 2, the distance between the cable and the corner of the frame between the two pulleys 1 is measured within a certain range to detect whether the cable is located on the pulley 1 and whether derailment has occurred. This allows for timely detection, further avoiding damage to the cable tray and cables, further reducing labor costs and improving construction efficiency.

[0021] Among them, the ranging device 4 can be an infrared ranging sensor or a laser ranging instrument.

[0022] Furthermore, it also includes BLE Bluetooth, which connects to the ranging device 4. BLE Bluetooth technology is a short-range, low-cost, interoperable wireless technology that can transmit data through miniature wireless sensors (exchanging data every half second). The ranging device 4 collects cable position data and simultaneously uploads the collected data to the control center via the BLE Bluetooth data upload function. If the cable disappears, it indicates that the cable has "derailed," and the control center can then alert on-site construction personnel to make timely adjustments to the construction site.

[0023] In one specific embodiment, the magnet 3 is a neodymium iron boron magnet 3, which can further increase the fixation stability of the laying auxiliary device.

[0024] In one specific embodiment, there are three auxiliary units; the three pulleys 1 are fastened to three separate frames 2 by bolts, and then the three frames 2 are connected by bolts at the corners to form a cable laying auxiliary device consisting of three detachable pulley 1 devices.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. If these modifications and variations fall within the scope of the claims of this utility model and their equivalents, they should be considered to be within the protection scope of this utility model.
