Example 1

[0019] Combination Figures 1-4 A lifting device for optical cable reels includes a movable frame 1, a hydraulic cylinder 2, and two sets of chain belts 3. The hydraulic cylinder 2 is fixedly installed inside the movable frame 1. The two sets of chain belts 3 are respectively connected to the outside of two rotating teeth at the top of the telescopic rod of the hydraulic cylinder 2. An adjustment component 4 is installed at the bottom of the two sets of chain belts 3, and two positioning components 5 are installed at the front end of the adjustment component 4.

[0020] See Figure 2 Furthermore, the adjustment assembly 4 includes a lifting frame 6, two guide rods 7 and an adjustment rod 8. The lifting frame 6 is fixedly installed at the bottom of the two sets of chain belts 3. The two guide rods 7 are fixedly installed at the front of the lifting frame 6. The adjustment rod 8 is movably installed through the center of the front of the lifting frame 6. A rocker plate 9 is installed at one end of the adjustment rod 8. Two guide blocks 10 are movably installed on the outside of the two guide rods 7 and the adjustment rod 8. A support frame 11 is fixedly installed at the bottom of the front of each of the two guide blocks 10.

[0021] The two ends of the chain belt 3 are fixedly connected to the moving frame 1 and the lifting frame 6 respectively. The chain belt 3 is meshed with the rotating teeth at the top of the telescopic rod of the hydraulic cylinder 2. The chain belt 3 drives the lifting frame 6 up and down through the telescopic rod of the hydraulic cylinder 2 to adjust the lifting height.

[0022] The lifting frame 6 is located at the front of the movable frame 1 and is slidably mounted up and down via a guide rail. The guide block 10 is located outside the guide rod 7 and is slidably mounted laterally. The guide rod 7 is used to guide the sliding of the guide block 10 so that the two support frames 11 remain balanced.

[0023] The two sets of threads on the outer wall of the adjusting rod 8 are arranged in opposite directions. The guide block 10 and the adjusting rod 8 are connected by threads. The adjusting rod 8 drives the two guide blocks 10 to slide inward or outward to adjust the distance between the two supports 11.

[0024] Specifically, the adjusting rod 8 drives the two guide blocks 10 to slide, adjusting the distance between the two supports 11 to match the specifications of the optical cable reel, which facilitates the adjustment of the supports 11 and is suitable for different lifting specifications of optical cable reels. Example 2

[0025] See Figure 3 and Figure 4Furthermore, based on Embodiment 1, the positioning component 5 includes a slide block 12, a positioning plate 13, and two sets of slide rods 14. The two sets of slide rods 14 are fixedly installed inside the support frame 11 near the front end. The slide block 12 is movably installed outside the two sets of slide rods 14 and located inside the support frame 11. The positioning plate 13 is fixedly installed on the top of the slide block 12. A spring 15 is sleeved on the outside of the slide rods 14. A cover plate 16 is installed at the bottom end of the slide rods 14 and located outside the support frame 11.

[0026] The slide block 12 is located outside the slide rod 14 and inside the support frame 11 and is slidably disposed. The top of the positioning plate 13 is rounded at the front corner. The slide block 12 is sleeved and installed inside the support frame 11 through the bottom end of the slide rod 14, so that the positioning plate 13 passes through the top surface of the support frame 11.

[0027] The two ends of the spring 15 are in contact with the bottom end of the slide 12 and the inner side of the cover plate 16, respectively. The cover plate 16 is connected to the support frame 11 by bolts. The slide 12 slides upward automatically by the spring 15, and the positioning plate 13 prevents the optical cable reel from sliding off.

[0028] Specifically, the slide block 12 is sleeved on the outside of the slide rod 14 through the outside of the support frame 11 and installed inside the support frame 11, so that the positioning plate 13 passes through the top surface of the support frame 11. The spring 15 is sleeved on the outside of the slide rod 14. The cover plate 16 is fixed to the outside of the support frame 11 by bolts. When the two support frames 11 support the optical cable reel, the optical cable reel contacts the rounded chamfer at the top of the positioning plate 13, so that the positioning plate 13 automatically retracts into the support frame 11. When the optical cable reel is located between the tops of the two support frames 11, the slide block 12 automatically slides upward under the action of the spring 15, so that the positioning plate 13 automatically pops out, and the positioning plate 13 prevents the optical cable reel from sliding off.

[0029] In actual operation, hydraulic cylinder 2 is manually pressed. The rotating teeth at the top of the extension rod of hydraulic cylinder 2 are connected to the chain belt 3 and provide support. When the extension rod of hydraulic cylinder 2 extends or retracts, the chain belt 3 drives the lifting frame 6 to rise or fall. The lifting frame 6 slides stably through the guide rail. During adjustment, the support frame 11 supports and lifts the optical cable reel. When lifting optical cable reels of different sizes, the rocker 9 is shaken to rotate the adjusting rod 8 and drive the two guide blocks 10 to slide inward or outward through the thread, thereby changing the distance between the two support frames 11. The distance between the two support frames 11 is adjusted to match the specifications of the optical cable reel, which facilitates the adjustment of the support frame 11 and is suitable for lifting optical cable reels of different specifications. During positioning, the slide block 12 is sleeved on the outside of the slide rod 14 through the outside of the support frame 11 and installed inside the support frame 11, so that the positioning plate 13 passes through the top surface of the support frame 11. The spring 15 is sleeved on the outside of the slide rod 14. The cover plate 16 is fixed to the outside of the support frame 11 by bolts. The cross-sectional shape of the optical cable reel is I-shaped, and the whole is a disc shape that is large at both ends and small in the middle. In use, the distance between the two support frames 11 is adjusted to be less than the maximum diameter of the optical cable reel. The cable reel can be placed within this distance. The two support frames 11 are forked on both sides of the optical cable reel. When the edge of the optical cable reel contacts the rounded chamfer at the top of the positioning plate 13, the positioning plate 13 automatically retracts into the support frame 11 to ensure that the optical cable reel can be easily picked up. When the support frame 11 rises so that the optical cable reel is between the top of the two support frames 11, the slide block 12 automatically slides upward under the action of the spring 15, so that the positioning plate 13 automatically pops out. The positioning plate 13 prevents the optical cable reel from sliding off due to vibration during movement.

The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical mechanisms, the control method and circuit connection will not be explained in detail.
