Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary equipment for laying low-voltage cables, and in particular relates to a low-voltage cable unwinding machine. Background Technology
[0002] To meet different transmission requirements and improve the reliability and sensitivity of the system, low-voltage cables are usually equipped with multiple conductors, and all cables are arranged neatly to facilitate maintenance and repair.
[0003] When laying low-voltage cables, in order to improve laying efficiency, the required cables are usually arranged in sequence on the bottom surface, and the axis of the coil seat with the low-voltage cables is perpendicular to the ground. Then, one end of all the low-voltage cables is pulled out at the same time. One worker stands at a high position and moves along the laying path to the starting connection end of the low-voltage cables, while another worker holds the middle of all the cables with one hand and winds them around the coil seat with the other hand, thereby realizing the unwinding of the cables.
[0004] During the unwinding process, multiple low-voltage cables are manually wound around to unwind them. The uneven stress on each cable can cause some cables to jam, forcing workers to stop and reducing work efficiency. Utility Model Content
[0005] To address the shortcomings of the existing technology, this utility model provides a low-voltage cable unwinding machine that can automatically unwind multiple low-voltage cables simultaneously. It has a simple structure and high efficiency.
[0006] In order to achieve the purpose of this utility model, the following solution is proposed:
[0007] A low-voltage cable unwinding machine, comprising:
[0008] The base has a set of brackets spaced apart on it. A U-shaped seat is provided on one side of the brackets. A rotating rod is strung between the brackets. The two ends of the rotating rod are rotatably connected to the corresponding U-shaped seats. The rotating rod has a hollow structure and multiple sets of circumferentially arranged limiting grooves are arranged along its axis on the outer periphery of the rotating rod. A top rod is inserted into the rotating rod. The top rod has a hollow structure and multiple sets of circumferentially arranged spring ears are arranged along its outer periphery on its axis. When the ring seat is inserted into the rotating rod, the spring ears are used to extend out of the corresponding limiting grooves and abut against the inner wall of the ring seat. One end of the rotating rod has a protrusion.
[0009] The drive assembly, which is movable along the length of the base at one end of the base, includes a vertically arranged movable plate. A set of synchronous pulleys is spaced apart on one side of the movable plate. The set of synchronous pulleys is connected to a synchronous belt. A motor is provided on the other side of the movable plate. The output end of the motor passes through the movable plate and is connected to one of the synchronous pulleys. A groove is recessed on one side of the synchronous pulley for engaging with a protrusion.
[0010] Furthermore, a set of U-shaped seats is arranged at intervals along the height direction of the support.
[0011] Furthermore, baffles are provided at both ends of the rotating rod, and the diameter of the baffles is larger than the opening of the U-shaped seat.
[0012] Furthermore, the lower end of the movable plate has an inverted T-shaped structure, and one end of the base is provided with an inverted T-shaped groove. The lower end of the movable plate slides in conjunction with the groove. The lower end of the movable plate is provided with a cylinder, and the output end of the cylinder extends into the groove and connects to the lower end of the movable plate.
[0013] Furthermore, reinforcing struts are provided on both sides of the support frame.
[0014] The beneficial effects of this utility model are as follows:
[0015] The coil holders, which are wrapped with low-voltage cables, are sequentially passed through the rotating rod. The springs on the top rod abut against the inner wall of the coil holders, so that the rotation of the rotating rod synchronously drives multiple coil holders to rotate, thereby realizing the automatic unwinding of low-voltage cables. This method is convenient and efficient. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0025] like Figures 1-6 As shown, this embodiment provides a low-voltage cable unwinding machine, including a base 10 and a drive assembly 20 disposed at one end of the base 10.
[0026] Specifically, such as Figures 1-2 As shown, the base 10 has a cuboid structure. A set of supports 11 is spaced apart along the length of the top surface of the base 10. To increase the strength and stability of the supports 11, reinforcing struts 111 are symmetrically and obliquely arranged on both sides of the supports 11. A U-shaped seat 12 is provided on one side of the support 11, and two U-shaped seats 12 are spaced apart along the height of the support 11, as shown... Figure 2 , Figures 4-5 As shown, a rotating rod 13 spans between a set of brackets 11. Both ends of the rotating rod 13 are rotatably connected to corresponding U-shaped seats 12. The inner wall of the rotating rod 13 is hollow. A top rod 14 is inserted and removed along the axis of the rotating rod 13, and the top rod 14 is hollow inside. Four sets of limiting grooves 131 are arranged circumferentially along the outer periphery of the rotating rod 13. Four sets of corresponding receiving grooves are arranged along the axis of the top rod 14. One end of each receiving groove has a spring 141, one end of which connects to one end of the receiving groove, and the other end matches the corresponding limiting groove 131. When the coil seat is inserted sequentially along the rotating rod 14, the spring 141 passes through the corresponding limiting groove 131 and abuts against the inner wall of the coil seat, thereby causing the coil seat to drive the low-voltage cable to move synchronously with the rotating rod 13. One end of the rotating rod 13 has a protrusion 132.
[0027] like Figure 1 , Figure 3As shown, the drive assembly 20 is located at one end of the base 10 along the length of the base 10 and corresponds to the end of the protrusion 132 of the rotating rod 13. The drive assembly 20 includes a moving plate 21, a set of synchronous pulleys 22, a synchronous belt 23, a motor 24, and a cylinder 25. The lower end of the moving plate 21 has an inverted T-shaped structure. One end of the base 10 is provided with an inverted T-shaped groove 15, so that the lower end of the moving plate 21 is slidably connected to the groove 15. A set of synchronous pulleys 22 are respectively connected to the side of the moving plate 21 facing the rotating rod 13 through rotating shafts, and the distribution trajectory of the set of synchronous pulleys 22 corresponds to the distribution trajectory of the U-shaped seat 12. The set of synchronous pulleys 22 are connected by the same synchronous belt 23. The motor 24 is located on the other side of the moving plate 21, and the output end of the motor 24 is connected to the rotating shaft corresponding to one of the synchronous pulleys 22. The cylinder 25 is located at one end of the base plate 10, and the output end of the cylinder 25 is connected to the moving plate 21. A set of synchronous pulleys 22 are recessed at one end facing the rotating rod 13 with a groove 221, and the rotating rod 13 is provided with a protrusion 132 at one end. When unwinding, the cylinder 25 pushes the moving plate 21 to move towards the bracket 11 so that the groove 221 aligns with the protrusion 132, thereby causing the motor 24 to drive the corresponding synchronous pulley 22, so that the driven synchronous pulley 22 drives another synchronous pulley 22 to rotate through the synchronous belt 23, thereby causing the rotating set of synchronous pulleys 22 to drive the corresponding rotating rod 13 to rotate, so as to realize the unwinding of the low-voltage line.
[0028] Specific operating procedures:
[0029] Insert the coil holders for the low-voltage cables sequentially along the axis of the rotating rod into the rotating rod 13. Using hoisting equipment, lift the rotating rod 13 upwards and move it to the corresponding U-shaped seat 12 on the bracket 11. Then, vertically lower the two ends of the rotating rod 13 into the corresponding U-shaped seat 12. Note that when inserting, first insert the rotating rod 13 with the coil holders for the low-voltage cables into the lower U-shaped seat 12, and then insert the rotating rod 13 with the coil holders for the low-voltage cables into the upper U-shaped seat 12 to facilitate insertion.
[0030] Restart cylinder 25 to push moving plate 21 toward bracket 11 so that groove 221 on synchronous wheel 22 aligns with protrusion 132 on rotating rod 13.
[0031] Finally, push the top rod 14 so that it moves along the axis of the rotating rod 13 toward the end where the protrusion 132 of the rotating rod 13 is located. This causes one end of the spring ear 141 to be freed from the obstruction of the outer wall of the top rod 14 and pop upward into the corresponding limiting groove 131. After passing through the corresponding limiting groove 131, it abuts against the inner wall of the coil seat of the low-voltage cable. Start the motor 24 so that the motor 24 drives the synchronous wheel 22 to rotate, thereby causing the synchronous belt 23 to drive another synchronous wheel 22 to rotate synchronously. This causes the upper and lower rotating rods 13 to rotate synchronously, so that multiple coil seats on the rotating rod 13 can rotate synchronously, thereby realizing the synchronous unwinding of multiple low-voltage cables. Note that the rotating rod 13 should rotate slowly during the unwinding process to avoid the cables from getting tangled together due to excessive unwinding speed.
[0032] Specifically, such as Figure 6 As shown, in order to prevent the rotating rod 13 from slipping out of the U-shaped seat 12, baffles 122 are provided at both ends of the rotating rod 13, and the protrusion 132 is located on the outside of one of the baffles 122. The diameter of the baffle 122 is larger than the opening of the U-shaped seat 12, so that the baffle 122 can play a limiting role.
[0033] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
