Description

Technical Field

[0001] This utility model relates to the field of wire feeding reel technology, and in particular to a wire feeding reel braking device and a wire feeding reel. Background Technology

[0002] Cable reels, commonly used for planning cable layout and measuring distances on construction sites, are a frequently used tool and fall under the category of construction machinery. They can also be used to store cables for easy retrieval when needed, improving work efficiency. Cable reels have wide applications in construction, civil engineering, and wire and cable manufacturing. For ease of use, the cable reel body is typically mounted on a braking device for control. However, existing cable reels and braking devices are not tightly connected, leading to relative rotation between the reel and braking device during cable laying, thus affecting braking performance. Therefore, there is an urgent need for a cable reel braking device and cable reel with a tight connection and good braking effect. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1-3 This utility model provides a wire feeding reel braking device and a wire feeding reel, including a fixed reel 1, a rotating shaft 2 rotatably connected to the fixed reel 1, and a rotating reel 3 fixedly connected to the rotating shaft 2. The rotating reel 3 is arranged parallel to the fixed reel 1. A braking assembly is provided on the fixed reel 1, located around the rotating shaft 2. A wire feeding reel body 4 is sleeved on the end of the rotating shaft 2 away from the fixed reel 1. A limiting component is provided between the rotating shaft 2 and the wire feeding reel body 4. By providing a braking assembly on the fixed reel 1 to brake the rotating shaft 2 and the fixed reel 1, it is easier to control the wire feeding reel body 4. By providing a limiting component between the rotating shaft 2 and the wire feeding reel body 4, the connection between the wire feeding reel body 4 and the rotating shaft 2 is strengthened, making it less prone to slippage during rotation, increasing its stability, and ensuring the braking effect.

[0018] The scheme is further optimized. The limiting component includes a receiving groove 5 opened in the rotating shaft 2. Two sliders 6 are slidably connected in the receiving groove 5. Several strip grooves 7 are opened along the axial direction of the rotating shaft 2. Limiting strips 8 are set in the strip grooves 7. The limiting strips 8 are located in the wire feeding reel body 4. Several connecting rod groups are rotatably connected between the two sliders 6. The connecting rod groups are correspondingly set with the limiting strips 8. The connecting rod group includes a first connecting rod 9 rotatably connected to one slider 6 and a second connecting rod 10 rotatably connected to the other slider 6. The first connecting rod 9 and the second connecting rod 10 are rotatably connected. The connection between the first connecting rod 9 and the second connecting rod 10 is rotatably connected to the middle of the corresponding limiting strip 8. A through groove 11 is opened on the bottom wall of the strip groove 7 for the first connecting rod 9 and the second connecting rod 10 to move. The through groove 11 is connected to the receiving groove 5. A control component for controlling the two sliders 6 to move towards each other is installed in the receiving groove 5. The control component drives the two sliders 6 to move towards each other, thereby squeezing the first connecting rod 9 and the second connecting rod 10. This causes the connection between the first connecting rod 9 and the second connecting rod 10 to move outward, thereby squeezing the limiting strip 8 to fit against the inner wall of the wire feeding reel body 4. This increases the tightness of the connection between the two and prevents them from rotating relative to each other due to rotational inertia during braking, thus ensuring the braking effect.

[0019] The scheme is further optimized, and the control component includes a bidirectional threaded rod 12 located within and rotatably connected to the receiving groove 5. The bidirectional threaded rod 12 is coaxially arranged with the rotating shaft 2. The bidirectional threaded rod 12 passes through two sliders 6 and is threadedly connected to the sliders 6. The two sliders 6 are located on opposite sides of the thread direction of the bidirectional threaded rod 12. The top end of the bidirectional threaded rod 12 passes through the top wall of the receiving groove 5 and is located outside the rotating shaft 2. An adjusting nut 13 is fixedly connected to the end of the bidirectional threaded rod 12 located outside the rotating shaft 2. The adjusting nut 13 has an internal hexagonal groove. By inserting a wrench into the internal hexagonal groove, the adjusting nut 13 is rotated, which in turn rotates the bidirectional threaded rod 12, thereby causing the two sliders 6 to move towards each other.

[0020] The braking assembly is further optimized by including a fixed post 14 fixedly connected to a fixed disc 1. One end of a brake band 15 is fixedly connected to the fixed post 14, and a brake pad is fixedly connected to the inner side of the brake band 15. The brake pad is located on the side of the rotating shaft 2. The other end of the brake band 15 is fixedly connected to a brake cable 16. A rotating rod 17 is rotatably connected to the side of the end face of the fixed disc 1. A connecting plate 18 is fixedly connected to the periphery of the rotating rod 17. The connecting plate 18 is fixedly connected to the end of the brake cable 16 away from the brake band 15. A lever 19 is fixedly connected to the periphery of the rotating rod 17. Pulling the lever 19 causes the connecting plate 18 to rotate via the rotating rod 17, thereby pulling the brake cable 16. The brake cable 16 pulls the brake band 15, causing the brake pad to fit tightly against the rotating shaft 2, thus completing the braking operation.

[0021] In a further optimized design, several mounting bases are fixedly connected to the fixed disk 1, and several rollers 20 are rotatably connected to the mounting bases. The axes of the rollers 20 are aligned with the radius of the fixed disk 1, and the end face of the rotating disk 3 contacts the rollers 20. The rollers 20 support the rotating disk 3, increasing its stability during rotation.

[0022] The working process of this utility model is as follows: In use, the main body 4 of the pay-off reel is directly sleeved on the rotating shaft 2. Then, a wrench is inserted into the internal hexagonal groove of the adjusting nut 13 to drive the adjusting nut 13 to rotate. The adjusting nut 13 drives the bidirectional threaded rod 12 to rotate, which in turn drives the two sliders 6 to move towards each other. This causes the first connecting rod 9 and the second connecting rod 10 to rotate relative to each other, thereby lifting the limiting strip 8 and making the limiting strip 8 abut against the inner wall of the pay-off reel main body 4, thereby increasing the stability of the connection between the two. When braking is required, the lever 19 is pulled. The lever 19 drives the connecting plate 18 to rotate through the rotating rod 17, thereby pulling the brake cable 16, causing the brake band 15 to drive the brake pads to fit tightly against the rotating shaft 2, thereby affecting the rotation of the rotating shaft 2 and completing the braking operation.
