Description

Technical Field

[0001] This utility model relates to the field of circulating cable replacement technology, specifically to a torque release device for replacing circulating cables in hydrological cableways. Background Technology

[0002] The circulation cable in a hydrological cableway primarily carries hydrological instruments and equipment to collect data such as current velocity, direction, water temperature, suspended sediment, and bedload at a certain depth underwater. The circulation cable is generally replaced every 3-5 years, but can be replaced immediately in special circumstances. Due to the large span of the cableway and the significant torque of the circulation cable, replacement poses certain safety risks. The lead weight suspending the circulation cable can rotate during use, causing the cable to accumulate considerable torque, which is normally counteracted by the weight of the lead weight. If the circulation cable becomes detached from the lead weight, the resulting torque could be enough to cause injury, posing a safety hazard.

[0003] Therefore, it is necessary to design a torque release device for changing the circulating cable of a hydrological cableway to solve the above-mentioned technical problems. Utility Model Content

[0016] like Figure 1 As shown, a torque release device for replacing the circulating cable of a hydrological cableway includes a bracket 1, a rolling bearing 2, a connecting shaft 3, and a connecting rod 7 and a fastening plate 5 that are interconnected. The rolling bearing 2 is fixedly connected to the bracket 1. One end of the connecting shaft 3 is rotatably connected to the rolling bearing 2. The other end of the connecting shaft 3 is detachably connected to the fastening plate 5 via a connector 6. The other end of the fastening plate 5 is provided with a connecting rod 7. The connecting rod 7 is detachably connected to a fastener 8. The connecting rod 7 is hollow and its diameter is adapted to the circulating cable to facilitate the installation of the circulating cable.

[0017] In this embodiment, the bracket 1 includes a first bracket 101 and a second bracket 102 integrally formed. The first bracket 101 and the second bracket 102 are V-shaped. The inner surfaces of the first bracket 101 and the second bracket 102 are connected to the outer surface of the rolling bearing 2. The first bracket 101 and the second bracket 102 further ensure the stability of the rolling bearing 2.

[0018] As a further technical solution of this embodiment, the other end of the first bracket 101 and the second bracket 102 are both provided with handles 4. The handles 4 are covered with protective sleeves. The handles 4 are designed to facilitate the operator's grip. The protective sleeves prevent wear on the handles 4 and also improve the operator's comfort and safety during operation.

[0019] As a further technical solution of this embodiment, the connector 6 includes a bolt 601 and a nut 602. The fastening plate 5 has a first through hole and a second through hole that are adapted to the bolt on both sides. The bolt passes through the first through hole, the ring 9 and the second through hole in sequence and is fastened by the nut 602, which facilitates quick installation and disassembly of the fastening plate 5.

[0020] As a further technical solution of this embodiment, the fastener 8 includes a plurality of screws, and the side of the connecting rod 7 is provided with a threaded hole adapted to the screws, and the screws are threadedly connected in the threaded hole; by the cooperation of the threaded hole and the screw, the wire rope is effectively fixed, preventing the wire rope from slipping or falling off during the torque release process, and further enhancing the reliability and stability of the device.

[0021] The working principle of this utility model: During use, the operator holds the handle 4 on the bracket 1, inserts the circulating cable through the hollow interior of the connecting rod 7 until it reaches the interior of the fastening plate 5, and fastens the circulating cable by threading the screw in the fastener 8 into the threaded hole to ensure that the circulating cable is locked. The operator releases handle 4, at which point the torque stored in the circulating cable is transmitted to the connecting shaft 3 through the fastening plate 5. The connecting shaft 3 rotates within the rolling bearing 2, thereby gradually releasing the torque of the circulating cable. Since the rolling bearing 2 is fixed on the V-shaped bracket 1, the stability of the bracket 1 ensures the smooth progress of the entire release process, avoiding any shaking or displacement that may occur during the torque release, and ensuring operational safety.

[0022] The torque release device of this invention is suitable for circulating cables with a diameter of 6mm or more; such as Figures 2 to 3 As shown, when the diameter of the circulating cable is less than 6mm, a simplified torque release device can be used, which specifically includes: a bracket 1, a rolling bearing 2, and a connecting shaft 3. The bracket 1 includes a first bracket 101 and a second bracket 102 arranged in a V-shape, and the first bracket 101 and the second bracket 102 are integrally formed. The rolling bearing 2 is welded to the bracket 1. One end of the connecting shaft 3 is rotatably connected to the rolling bearing 2, and the other end of the connecting shaft 3 is provided with a ring 9, which is also provided with a fixing part. The ring 9 is provided for hanging the circulating cable and fixing it through the fixing part thereon. In operation, this simplified torque release device also involves first passing the circulating cable through the ring 9 and securing it with the fixing part. The operator holds the handle 4 of the bracket 1. As the torque contained in the circulating cable is released, the connecting shaft 3 rotates within the rolling bearing 2. The V-shaped bracket 1 provides stable support for the rolling bearing 2, ensuring a smooth torque release process, reducing the impact of shaking caused by torque release on the operator, and ensuring operational safety. Moreover, this simplified device has a simpler structure and is more suitable for scenarios where there are requirements on the diameter of the circulating cable, the size of the device, and cost.
