Description

Technical Field

[0001] The invention relates to the technical field of cable reels, in particular to a high-voltage cable reel. Background Art

[0002] High-voltage cable reel is a device used to store, transport and install high-voltage cables. It is usually used in the power industry, power construction projects, industrial and mining enterprises, etc. Its main function is to keep the cable neatly wound to avoid damage to the cable during use, while facilitating the rapid deployment and retraction of the cable.

[0003] The high-voltage cable is wound through the spokes or drums of the reel, ensuring that the cable is not pulled or worn. When unwinding the cable, the reel will unwind the cable evenly to avoid excessive bending or damage to the cable sheath. When retracting the cable, the reel will roll up the cable neatly for easy transportation and storage.

[0004] In the prior art, the size of the cable reel is relatively fixed. When the length of the cable is long, in order to accommodate the longer cable, the size of the reel usually needs to be increased, which will reduce the flexibility of the cable during transportation and make the placement, handling and loading and unloading of the cable more troublesome. Therefore, a high-voltage cable reel is proposed to solve the above problems. Summary of the invention

[0005] In order to remedy the above deficiencies, the present invention provides a high-voltage cable reel, aiming to improve the problem that the size of the cable reel in the prior art is relatively fixed and cannot be applied to cables of different lengths, resulting in reduced flexibility of the cable during transportation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a high-voltage cable reel, including a main reel, wherein two groups of symmetrically arranged extension cylinders are slidably connected inside the main reel, an annular baffle is fixedly connected to the end of the extension cylinder, and the inner wall of the main reel is provided with multiple groups of guide grooves distributed in an array, and the surface of the extension cylinder is fixedly connected with a guide strip, and the guide strip is slidably connected inside the guide groove.

[0007] As a further description of the above technical solution: The surface of the main reel is provided with a limiting groove connected with the guide groove, the inner wall of the limiting groove is provided with a plurality of array-distributed slots, the surface of the guide strip is fixedly connected with a protrusion, and the protrusion is slidably connected inside the limiting groove.

[0008] As a further description of the above technical solution: A mounting groove is provided on the surface of the protrusion, a limiting assembly is arranged inside the mounting groove, and the limiting assembly includes a slide plate, which is slidably connected inside the mounting groove, and a plug block is fixedly connected to the side wall of the slide plate.

[0009] As a further description of the above technical solution: The slide plates are symmetrically arranged in two groups, and the two groups of slide plates are elastically connected via a return spring.

[0010] As a further description of the above technical solution: A through hole is formed on the side wall of the slide plate, and a guide rod is slidably connected in the through hole, and the end of the guide rod is fixedly connected to the outer wall of the mounting groove.

[0011] As a further description of the above technical solution: The guide rods are provided in two groups, and the two groups of guide rods are symmetrically arranged with the vertical center line of the slide plate as the symmetry axis.

[0012] As a further description of the above technical solution: The inserting block penetrates and is slidably connected to the side wall of the protrusion, and the inserting block is inserted into the interior of the card slot.

[0013] The present invention has the following beneficial effects: 1. In the present invention, by pressing two sets of slide plates at the same time, the slide plates compress the reset spring, and at the same time the slide plates drive the insert block to move out of the slot. At this time, the position of the extension tube can be adjusted, thereby realizing the length extension of the cable reel, effectively increasing the overall length of the cable reel, thereby adapting to the requirements of cable reeling and releasing of different lengths.

[0014] 2. In the present invention, when the extension tube slides to a suitable length, the protrusion slides to correspond to the corresponding slot position. Under the action of the reset spring, the two sets of slides move back to back, and the movement of the slides drives the insertion block to move synchronously, so that the insertion block is inserted into the corresponding slot, thereby fixing the position of the extension tube and ensuring the stability of the extension tube during the cable winding process.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1 - Figure 2 The present invention provides an embodiment: a high-voltage cable reel, including a main reel 1, two groups of symmetrically arranged extension cylinders 2 are slidably connected inside the main reel 1, and an annular baffle 3 is fixedly connected to the end of the extension cylinder 2. The extension cylinder 2 can extend from the main reel 1, thereby realizing the length extension of the cable reel, effectively increasing the overall length of the cable reel, thereby meeting the requirements of cable reeling and releasing of different lengths.

[0019] Reference Figure 1 - Figure 2 The inner wall of the main reel 1 is provided with a plurality of guide grooves 11 distributed in an array, and the surface of the extension drum 2 is fixedly connected with a guide bar 21, and the guide bar 21 is slidably connected inside the guide groove 11. The function of the guide groove 11 is to provide a guide channel so that the extension drum 2 can slide smoothly inside the main reel 1, and during the process of winding the cable, ensure that the extension drum 2 rotates synchronously with the main reel 1.

[0020] Reference Figure 1 - Figure 2 The surface of the main reel 1 is provided with a limit groove 12 connected to the guide groove 11, and the inner wall of the limit groove 12 is provided with a plurality of array-distributed clamping grooves 13, and the surface of the guide strip 21 is fixedly connected with a protrusion 22, and the protrusion 22 is slidably connected to the inside of the limit groove 12. The cooperation between the limit groove 12 and the protrusion 22 ensures that the extension tube 2 can only slide within a certain range, and the clamping groove 13 in the limit groove 12 cooperates with the limit assembly 4 to achieve the fixing of the extension length of the extension tube 2.

[0021] Reference Figure 2 - Figure 3A mounting groove 23 is provided on the surface of the protrusion 22, and a limit assembly 4 is provided inside the mounting groove 23. The limit assembly 4 includes a slide plate 41, and the slide plate 41 is slidably connected inside the mounting groove 23. The slide plates 41 are symmetrically arranged in two groups, and the two groups of slide plates 41 are elastically connected by a return spring 42. The return spring 42 provides elastic support between the two groups of slide plates 41, so that the two groups of slide plates 41 move back to back. A through hole is provided on the side wall of the slide plate 41, and a guide rod 43 is slidably connected in the through hole. The end of the guide rod 43 is fixedly connected to the outer wall of the mounting groove 23. A through hole is provided on the side wall of the slide plate 41, and a guide rod 43 is slidably connected in the through hole. The end of the guide rod 43 is fixedly connected to the outer wall of the mounting groove 23. Reference Figure 3 The two sets of guide rods 43 are used to guide the slide plate 41 so that the slide plate 41 can stably slide inside the mounting groove 23, and the return spring 42 is sleeved on the outside of the guide rods 43 to prevent the return spring 42 from excessive bending during the compression process of the return spring 42. The side wall of the slide plate 41 is fixedly connected with an insert block 44, which penetrates and is slidably connected to the side wall of the protrusion 22, and the insert block 44 is inserted into the inside of the card slot 13. The movement of the slide plate 41 drives the insert block 44 to move synchronously, so that the insert block 44 is inserted into the card slot 13, thereby fixing the extended length of the extension tube 2.

[0022] Working principle: When it is necessary to adjust the length of the high-voltage cable reel, press the two sets of slide plates 41 at the same time. The slide plates 41 compress the reset spring 42, and the slide plates 41 drive the plug block 44 to move out of the slot 13. At this time, the position of the extension tube 2 can be adjusted. By pulling the extension tube 2 outward, the extension tube 2 drives the guide bar 21 to slide in the guide groove 11, and the protrusion 22 slides in the limit groove 12. When the extension tube 2 slides to a suitable length, the protrusion 22 just slides to the position corresponding to the corresponding slot 13. Under the action of the reset spring 42, the two sets of slide plates 41 move back to back, and the movement of the slide plates 41 drives the plug block 44 to move synchronously, so that the plug block 44 is inserted into the corresponding slot 13, thereby fixing the position of the extension tube 2 and realizing the adjustment of the length of the high-voltage cable reel.
