Description

Technical Field

[0001] This utility model relates to the field of mechanical structures, specifically to a damping device on a cable reel. Background Technology

[0002] Portable cable reels are used to wind power cables, signal cables, and data transmission cables. Both ends of the cable must connect to matching connectors. They are designed for long-distance, field use, and can be repeatedly wound and unwound for easy portability. Generally, the cable reel's winding speed is adjusted by a damping device, preventing excessively fast unwinding that could cause tangling and knots, allowing for quick cable use. However, most cable reel assemblies lack this damping speed adjustment, resulting in inconsistent unwinding speeds. This leads to excessively fast unwinding, tangling, and significantly reduces cable lifespan.

[0003] A damping device is described in the earlier application (2025205373774) that can solve the above problems. However, in actual use, there is a special type of cable reel that is limited by space and cannot be equipped with a damping device according to the structure in the application. Therefore, it is necessary to consider the damping structure from other perspectives. Utility Model Content

[0004] The purpose of this invention is to improve the damping structure based on existing technology, so as to achieve damping that can meet the requirements of some space-constrained conditions.

[0005] The present invention adopts the following technical solution: a damping device on a cable reel, comprising a damping bracket disposed on a cable reel support, and a damping elastic element disposed on the damping bracket, wherein one end of the damping elastic element is in elastic contact with the surface of the cable reel.

[0006] In the above technical solution, the damping elastic element includes a sleeve, a pull rod and a spring disposed inside the sleeve, and a damping plate is disposed on one end of the pull rod that passes through the sleeve.

[0007] In the above technical solution, a baffle is provided inside the sleeve, and the spring is disposed between the baffle and the damping bracket.

[0008] In the above technical solution, a limiting step is provided inside the sleeve, the baffle is disposed on the limiting step, and the pull rod can pass through the baffle and drive the baffle to move.

[0009] In the above technical solution, an end cap is provided on the other end of the pull rod that passes through the sleeve, and a locking pin is provided at the connection between the pull rod and the end cap.

[0010] In the above technical solution, a groove is provided on the end face of the sleeve, and the locking pin can slide out of the sleeve and engage with the groove.

[0011] In the above technical solution, the sleeve is provided with a groove in the axial direction, and the locking pin can slide along the groove and extend into or out of the sleeve.

[0012] In the above technical solution, the locking pin on the pull rod can drive the baffle to move.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] This invention solves the problem of damping the cable reel in situations where space is limited, especially when there is limited space between the cable support and the cable reel. It enables control of the cable reel's rotation speed, provides a certain degree of vibration reduction during the cable laying process, effectively reduces bumps and vibrations, improves operator comfort, and is suitable for long-term field operations.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1As shown, cable 1 is wound on cable reel 2, and cable reel 2 is set on cable reel bracket. Because the connection space between cable reel bracket and cable reel 2 is small, the damping structure set on the rotating shaft of cable reel 2 in the prior art cannot be applied in the corresponding structure of this embodiment. Therefore, in this embodiment, damping structure 3 is set on the side of cable reel 2 and fixed on cable reel bracket. One end of damping structure 3 makes frictional contact with cable reel 2.

[0024] like Figure 2 As shown, the damping structure 3 is fixed to the damping bracket 4, which is used to fix the cable reel bracket. The damping structure 3 includes a sleeve 7 fixedly connected to the damping bracket 4. A pull rod that can move axially is provided inside the sleeve 7. One end of the pull rod extending out of the sleeve 7 is connected to a damping plate 5, and the other end is connected to an end cap 6. A locking pin 8 is connected to the pull rod at one end of the end cap 6. A groove is provided on the sleeve 7 corresponding to the locking pin 8, so that the locking pin 8 can move axially within the sleeve 7. At the same time, a slot is provided on the end face of the sleeve 7, so that the locking pin 8 can extend out of the sleeve 7 and engage with the slot.

[0025] like Figure 3 As shown, to provide elastic recovery, a spring 10 is installed inside the sleeve 7, and the pull rod 11 passes through the spring 10. A baffle 9 is installed inside the sleeve 7 to block and compress the spring 10. Specifically, a limiting step is provided inside the sleeve 7 to confine the baffle 9 to the limiting step. During the reset process after the baffle 9 compresses the spring 10, the baffle 9 will not be ejected from the sleeve 7 by the spring 10.

[0026] Because of the setting of elastic damping, it needs to be set so that the pull rod 11 drives the baffle 9 to move. Therefore, the baffle 9 is pushed to move by the locking pin 8, so that the damping structure 3 can achieve frictional damping of the cable reel 2.

[0027] The working principle of the entire damping is specifically manifested as follows:

[0028] When the cable reel is in a natural, unused state, the damping plate 5 comes into contact with the cable reel 2. Under the action of the spring 10, the two are in an elastic connection, and the cable reel 2 will be subjected to frictional damping from the damping plate 5.

[0029] When the cables on cable reel 2 need to remain in a certain stationary state, such as Figure 2 As shown, by pressing down the end cap 6, the locking pin 8 presses down the baffle 9, which in turn drives the spring 10 and the pull rod 11 to make the damping plate 5 contact with the cable reel 2. Under the action of frictional damping, the cable reel 2 stops rotating. At the end, the end face 6 is released, and under the action of the spring 10, the locking pin 8 separates from the baffle 9, and the damping plate 5 will resume its natural contact with the cable reel 2.

[0030] When cable reel 2 needs to quickly unload cables, such as Figure 4 As shown, pull the end cap 6 so that it slides out of the sleeve 7 from the locking pin 8. Then rotate the end cap 6, causing the locking pin 8 to shift. After the locking pin 8 shifts, it engages with the slot on the end cap 6. During this process, the pull rod 11 causes the damping plate 5 to separate from the cable reel 2. The cable reel 2 is no longer subject to frictional damping, allowing it to rotate quickly to unload the cable. At the end, reverse the operation to restore the damping plate to its natural contact with the cable reel 2.

[0031] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
