DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.
[0022] As shown Figures 1-4 in the figure, a new intermediate drag chain system for a turntable includes a wiring panel surface 1. The wiring panel surface 1 is circularly arranged and has a plurality of wiring panel wire outlet holes 11 penetrating through its surface. The wiring panel wire outlet holes 11 are used to place fixed cable wiring ports. Below the wiring panel surface 1 is connected a wiring panel protective cylinder 2. The wiring panel protective cylinder 2 is hollow and is used to place cables and protect the cables inside. Below the wiring panel protective cylinder 2 is connected a horizontal connecting plate 3. Above the horizontal connecting plate 3 is provided a guide groove lower guard plate 31. Around the lower end of the wiring panel protective cylinder 2 is provided a guide groove inner guard plate 5. The guide groove inner guard plate 5 is circularly arranged. The lower end of the guide groove inner guard plate 5 is fixedly connected to the guide groove lower guard plate 31. Around the upper periphery of the guide groove lower guard plate 31 is fixedly connected a guide groove outer guard plate 4. The guide groove outer guard plate 4 is circularly arranged and has the same height as the guide groove inner guard plate 5. Above the guide groove lower guard plate 31 is provided a drag chain 6. One end of the drag chain 6 close to the guide groove inner guard plate 5 is connected with a first drag chain port 61. The other end of the drag chain 6 is connected with a second drag chain port 62. The second drag chain port 62 is fixedly connected to a drag chain traction plate 7. The drag chain 6 is composed of a chain made of insulating material and connecting parts, etc., and can be freely bent to protect the cables inside. One end of the drag chain 6 is fixed on the guide groove lower guard plate 31, and the other end is fixedly connected to the turntable through the drag chain traction plate 7. When the turntable rotates, it pulls one end of the drag chain 6 to move along the guide groove outer guard plate 4, so that the cables are not damaged by friction during the movement process.
[0023] Among them, the drag chain 6 is arranged between the guide groove outer guard plate 4 and the guide groove inner guard plate 5. A drag chain wire outlet hole 51 is opened on the side of the guide groove inner guard plate 5 close to the first drag chain port 61. The cable passes through the drag chain wire outlet hole 51 and enters the inside of the drag chain 6 and passes through the drag chain 6 and exits from the second drag chain port 62.
[0024] As shown Figure 1 in the figure, a plurality of first fixing holes 12 are circumferentially distributed around the periphery of the wiring panel surface 1. Threaded holes matching thereto are provided above the wiring panel protective cylinder 2. The wiring panel surface 1 is installed above the wiring panel protective cylinder 2 through bolts. Above the guide groove lower guard plate 31 is fixedly connected a drag chain limiting plate 32. The drag chain limiting plate 32 is circular-arc-shaped and has arc-shaped round corners at both ends. When the drag chain traction plate 7 drives the drag chain 6 to enter between the guide groove outer guard plate 4 and the drag chain limiting plate 32, the drag chain limiting plate 32 limits the drag chain 6 to prevent the drag chain 6 from being blocked inside the guide groove due to excessive bending angle during rotation, causing damage to the drag chain 6 and the cables when the turntable rotates.
[0025] Please refer to Figure 2 , a plurality of third fixing holes 33 are provided on the surface of the guide groove lower guard plate 31. The guide groove lower guard plate 31 is fixedly installed above the horizontal connecting plate 3 through bolts.
[0026] The surface of the wiring panel casing 2 is provided with a number of through holes, and the bottom of the wiring panel casing 2 is provided with a central wire outlet hole 21. The through holes on the surface of the wiring panel casing 2 are not only conducive to ventilation and heat dissipation, but also facilitate the inspection and maintenance of the internal cables.
[0027] A plurality of second fixing holes 22 distributed in a circular pattern are formed at the lower end of the wiring panel casing 2, and threaded holes corresponding to the second fixing holes 22 are formed on the surface of the transverse connecting plate 3. The wiring panel casing 2 is mounted above the transverse connecting plate 3 by bolts.
[0028] The principle of the present utility model is as follows: The device is installed at the center of the turntable. External cables enter the wiring panel casing 2 through the central wire outlet hole 21. Some cables enter the drag chain 6 through the drag chain wire outlet hole 51 and pass through the other end of the drag chain 6 to be connected to the electrical components of the turntable. The turntable is fixedly connected to the drag chain traction plate 7. When the turntable rotates, it drives the drag chain 6 to move in the guide groove and presents an S-shaped bend. At the same time, the wiring ports of some cables are led out through the wiring panel wire outlet holes 11 provided on the wiring panel surface 1. The cables inside the drag chain 6 and the wiring panel casing 2 will not rub against the turntable when the turntable rotates, avoiding damage to the cables due to long-term friction. The wiring panel surface 1 and the wiring panel casing 2, as well as the wiring panel casing 2 and the transverse connecting plate 3, are all fixedly connected by bolts, which can be modularly installed, and the wiring panel casing 2 of a matching size can be selected according to the height of different turntables, with higher applicability.
[0029] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
