Description

Technical Field

[0001] This utility model relates to the field of factory wiring technology, specifically to a factory cable tray wiring device and a factory cable tray wiring fixture. Background Technology

[0002] During the construction of a large steel structure new factory building, it is necessary to route the cables for various machining and electronic equipment within the factory to ensure the normal operation of the equipment, avoid safety hazards caused by messy, overlapping, or crisscrossing wiring, and also improve the aesthetics of the factory building. The wiring process involves first erecting cable trays on the ceiling of the factory building, and then laying the cables on the trays. Cable trays are typically made of steel or aluminum, and are characterized by high strength, light weight, and corrosion resistance, providing support and protection for the cables.

[0003] During cable laying, the cable needs to be pulled from one end of the cable tray to the other. Current technology typically involves multiple people working together to pull and install the cable: one person lays the cable at the cable reel; two to three people work below the cable tray to move the cable onto it; and the remaining workers are positioned on the overhead crane beam to pull the cable neatly onto the tray. Because the cable tray is some distance from the ground, at least one worker must stand on the ground while another is elevated, working together to lift the cable. Since the cable is relatively heavy, this makes the work physically demanding, and after prolonged work, they may find it difficult to hold onto the cable, causing it to fall. If the falling cable hits a pillar in the factory, it can easily damage its surface. Furthermore, manual lifting and moving of the cable results in a slow installation speed. Utility Model Content

[0004] This utility model provides a cable routing device for factory cable trays to overcome the aforementioned problems in the prior art. The cable routing device includes a guide wheel, a fixed shaft, and two fixing devices. During cable laying, the two fixing devices are respectively fixed to the columns on both sides of the factory cable tray, and the cable is installed in the guide groove of the guide wheel. The guide wheel supports and limits the cable. At this time, only one person needs to stand next to the guide wheel and adjust the direction of the cable to deliver the cable onto the cable tray. The operation is very labor-saving, greatly reducing the labor intensity of workers. Moreover, the cable is less likely to shake and fall during dragging, which helps to improve the installation speed of the cable and reduce the risk of damage. Correspondingly, this application also provides a tooling for cable routing in factory cable trays.

[0005] For wiring devices, the technical solution of this application is as follows:

[0006] A cable routing device for factory cable trays includes a guide wheel, a fixed shaft, and two fasteners. The guide wheel is fitted onto the middle of the fixed shaft. The two fasteners are threaded to both ends of the fixed shaft and can move relative to the fixed shaft. The two fasteners are symmetrically distributed on both sides of the guide wheel. A guide groove is provided on the outer circumference of the guide wheel for installing cables. Bearings are embedded at both ends of the guide wheel. The fixed shaft forms a rotating pair with the guide wheel through the bearings. During cable routing, the two fasteners are fixed to the columns on both sides of the factory cable tray, and the cables are installed in the guide grooves of the guide wheel.

[0007] Compared with existing technologies, the cable routing device for factory cable trays in this application has a reasonable overall structural design, low manufacturing cost, and convenient installation. It includes a guide wheel, a fixed shaft, and two fasteners. During the cable laying process, the two fasteners are fixed to the columns on both sides of the factory cable tray, and the cable is installed in the guide groove of the guide wheel. At this time, only one person needs to stand next to the guide wheel and adjust the direction of the cable to send the cable onto the cable tray. The operation is very labor-saving, greatly reducing the labor intensity of workers and reducing labor costs. Moreover, the cable is supported and limited by the guide wheel, making it less likely to fall off during dragging, which helps to improve the installation speed of the cable and also reduces the risk of cable damage during installation. In addition, the fasteners and the fixed shaft are connected by threads. In actual use, the overall length of the routing device can be changed by adjusting the distance between the ends of the fasteners and the fixed shaft, so that it can be applied to factory structures of different widths.

[0008] As an optimization, in the aforementioned factory cable tray wiring device, the fixing device includes a threaded sleeve fitted onto the end of a fixing shaft; three fixing claws are evenly distributed circumferentially on the outer circumferential surface of the threaded sleeve. The fixing device uses a three-claw fixing method, resulting in high installation stability, allowing the wiring device of this application to be stably mounted between factory columns. Furthermore, the fixing claws are L-shaped and welded to the threaded sleeve. This results in a simple structure and convenient manufacturing. Further, the ends of the fixing claws are provided with rubber sleeves. The rubber sleeves increase the friction between the fixing device and the factory columns, and their elasticity allows for good contact with the column surface even on uneven surfaces, further improving the installation stability between the fixing device and the columns.

[0009] As an optimization, in the aforementioned factory cable tray wiring device, the guide groove has a V-shaped cross-section. The guide wheel adopts a V-shaped structure design, so that the cable can be placed with uniform force, is not easy to shake or shift, and the diameter of the cable is not greatly restricted.

[0010] As an optimization, in the aforementioned factory cable tray wiring device, the guide wheel can be a nylon guide wheel; the fixed shaft and the fixture can be made of stainless steel.

[0011] For wiring fixtures, the technical solution of this application is as follows:

[0012] A cable routing fixture for factory cable trays includes two uprights on both sides of the cable tray and a routing device fixed between the two uprights. The routing device includes a guide wheel, a fixed shaft, and two fasteners. The guide wheel is sleeved in the middle of the fixed shaft. The two fasteners are threaded to both ends of the fixed shaft and can move relative to the fixed shaft. The two fasteners are symmetrically distributed on both sides of the guide wheel. A guide groove is provided on the outer circumference of the guide wheel for installing cables. Bearings are embedded at both ends of the guide wheel. The fixed shaft forms a rotating pair with the guide wheel through the bearings.

[0013] Compared with the prior art, the cable laying fixture for factory cable trays in this application, by setting up a cable laying device with a specific structure, cooperates with the columns on both sides of the cable tray to support and limit the cable. This allows only one person to deliver the cable to the cable tray during the cable laying process, reducing labor costs and the labor intensity of workers. Moreover, the cable is less likely to fall off during dragging, which helps to improve the installation speed of the cable and reduce the risk of cable damage during installation.

[0014] As an optimization, in the aforementioned cable tray wiring fixture for factory buildings, the fixing device includes a threaded sleeve fitted onto the end of a fixing shaft; three fixing claws are evenly distributed circumferentially on the outer circumferential surface of the threaded sleeve. The fixing device uses a three-claw fixing method, resulting in high installation stability, allowing the wiring device of this application to be stably positioned between factory columns. Furthermore, the fixing claws are L-shaped and welded to the threaded sleeve. This results in a simple structure and convenient manufacturing. Further, the ends of the fixing claws are provided with rubber sleeves. The rubber sleeves increase the friction between the fixing device and the factory columns, and their elasticity allows them to conform well to the column surface even if it is uneven, further improving the installation stability between the fixing device and the columns.

[0015] As an optimization, in the aforementioned cable tray wiring fixture for factory buildings, the guide groove has a V-shaped cross-section. The guide wheel adopts a V-shaped structure design, which ensures that the cable is evenly stressed and not easily shakes or shifts when placed, and also does not impose too many restrictions on the diameter of the cable.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] During the initial laying and subsequent addition of cables within the factory, it is necessary to pull the cables from one end of the cable tray to the other. Current technology typically involves 8-10 people working together to pull and install the cables: one person lays the cable at the cable reel; 2-3 people below the cable tray deliver the cable onto the tray; and the remaining people are spaced apart on the overhead crane beam to pull the cable. The worker responsible for delivering the cable below the cable tray needs at least one person standing on the ground while another is elevated, working together to lift the cable upwards; this method is slow and physically demanding.

[0022] In view of this, the inventor provides a cable routing device for factory cable trays, including a guide wheel, a fixed shaft, and two fasteners; in use, the two fasteners 3 are respectively fixed to the columns 7 on both sides of the factory cable tray 6, and the cable 5 is installed in the guide groove 101 of the guide wheel 1 (see...). Figure 4 The cable 5 is supported and limited by the guide wheel 1. At this time, only one person needs to stand next to the guide wheel 1 and adjust the direction of the cable 5 to send the cable 5 onto the cable tray 6. The operation is quick and convenient, with low labor intensity and high installation efficiency. The specific structure is as follows.

[0023] Example:

[0024] See Figure 1The cable routing device for the factory cable tray in this embodiment includes a guide wheel 1, a fixed shaft 2, and two fasteners 3. The guide wheel 1 is sleeved in the middle of the fixed shaft 2. The two fasteners 3 are respectively threaded to both ends of the fixed shaft 2 and can move relative to the fixed shaft 2. The two fasteners 3 are symmetrically distributed on both sides of the guide wheel 1 (the guide wheel 1 is located in the middle to ensure uniform force distribution). The guide wheel 1 has a guide groove 101 in the middle for installing the cable 5. Bearings 4 are embedded in both ends of the guide wheel 1. The fixed shaft 2 forms a rotating pair with the guide wheel 1 through the bearings 4 (the design of the bearings 4 can be used to ensure the working position and rotation accuracy of the fixed shaft 2). During installation, the routing device is placed parallel to the ground between two columns 7. Then, the fasteners 3 on both sides are rotated so that the ends of the fasteners 3 contact the outer surface of the columns 7 and are tightened to fix the fasteners 3 to the columns 7.

[0025] See Figure 2 In this embodiment, the fixture 3 includes a threaded sleeve 31 fitted onto the end of the fixed shaft 2; three fixing claws 32 are evenly distributed circumferentially on the outer circumferential surface of the threaded sleeve 31. The fixture 3 adopts a three-claw fixing method, which provides high installation firmness, allowing the wiring device of this application to be stably positioned between the factory columns 7. Furthermore, the fixing claws 32 are L-shaped and are welded to the threaded sleeve 31. This results in a simple structure and convenient manufacturing. Furthermore, the ends of the fixing claws 32 are provided with rubber sleeves 33. The rubber sleeves 33 can increase the friction between the fixture 3 and the factory columns 7, and the rubber sleeves 33 are elastic, so even if the surface of the column 7 is uneven, they can fit well against the surface of the column 7, thereby further improving the installation firmness between the fixture 3 and the column 7.

[0026] See Figure 3 In this embodiment, the cross-section of the guide groove 101 is V-shaped. The guide wheel 1 adopts a V-shaped structure design, so that the cable 5 can be evenly stressed and is not easy to shake or shift when placed, and the diameter of the cable 5 is not greatly limited.
