[0003] The main function of the braking device in the existing casing hanger is to ensure the stability and safety of the casing during suspension. Although the casing hanger itself does not directly include a braking device in the traditional sense, it achieves a similar braking effect through specific designs and structures. However, when locking the casing hanger, it requires manual operation by staff. Such manual operation cannot quickly respond to control signals, which may lead to the inability to lock the casing in a timely manner in case of an emergency, increasing the safety risk. At the same time, this not only consumes time and effort but may also lead to inaccurate or delayed operations due to human factors. Content of the Utility Model

[0029] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a braking device for a casing hanger, including a mounting base 1;

[0030] A braking device is provided on the mounting base 1;

[0031] The braking device includes a rotating sleeve 12, a rotating gear 13 and three locking blocks 7. One end of the rotating sleeve 12 is rotatably connected to the upper surface of the mounting seat 1, and one end of the rotating gear 13 is rotatably connected to the upper surface of the mounting seat 1. The outer wall of the end of the rotating sleeve 12 close to the mounting seat 1 is provided with teeth, and the outer wall teeth of the rotating gear 13 mesh with the lower teeth of the rotating sleeve 12. Three locking block grooves 5 are formed in the outer wall of the rotating sleeve 12, and all three locking block grooves 5 are arc-shaped. Mounting blocks 15 are installed at one end of the mounting seat 1 close to the rotating sleeve 12. Fixing rod grooves 14 are formed in the upper surfaces of the three locking blocks 7. Fixing rods 11 are fixedly connected to the interiors of the three locking block grooves 5 respectively. The interiors of the three fixing rod grooves 14 are respectively slidably connected to the outer walls of the corresponding fixing rods 11. One ends of the three locking blocks 7 are respectively rotatably connected to the upper surfaces of the corresponding mounting blocks 15. A motor 8 is installed at one end of the mounting seat 1 away from the mounting seat 1. The outer walls of the three locking blocks 7 are respectively slidably connected to the interiors of the corresponding locking block grooves 5. The output end of the motor 8 rotates and extends to the outside of the mounting seat 1 and is fixedly connected to one end of the rotating gear 13. Limiting teeth 6 are installed on the outer walls of the three locking blocks 7 away from the mounting blocks 15.

[0032] Among them, three fixing blocks 3 are fixedly connected to the outer wall of the mounting seat 1. Fixing bolts 2 are threadedly connected to the outer walls of the three fixing blocks 3. A connecting shaft 9 is installed inside the rotating sleeve 12. One end of the connecting shaft 9 close to the mounting seat 1 passes through the rotating sleeve 12 and extends to the outside of the mounting seat 1. The outer walls of the three limiting teeth 6 are all in contact with the outer wall of the connecting shaft 9. A second internal thread 16 is formed in the inner wall of the end of the connecting shaft 9 close to the rotating sleeve 12. A hanger 4 is arranged outside the mounting seat 1. The external thread at one end of the hanger 4 is threadedly connected to the interior of the second internal thread 16. A first internal thread 10 is formed in the inner wall of the end of the connecting shaft 9 away from the second internal thread 16.

[0033] Further, when using this device, it is started by connecting to an external power supply. First, connect the first internal thread 10 at one end of the connecting shaft 9 to an external device to complete the installation. Then, connect the mounting seat 1 to the external device through the fixing bolts 2 on the three fixing blocks 3, and at the same time drive the rotating gear 13 to rotate through the rotation of the output end of the motor 8, which drives the rotating sleeve 12 to rotate. Then, the rotation of the rotating sleeve 12 drives the fixing rod 11 to rotate with the rotating sleeve 12, and at the same time drives the three locking blocks 7 to lock the outer wall of the connecting shaft 9, thus avoiding the need for operators to manually lock, effectively improving the working efficiency of the operators. Then, the hanger 4 can be screwed to disconnect the other end from the interior of the second internal thread 16 to complete the disassembly.

[0034] The rotation of the output end of the motor 8 in the braking device drives the rotation of the rotating gear 13, which in turn drives the rotation of the rotating sleeve 12. Then, the rotation of the rotating sleeve 12 drives the fixed rod 11 to rotate with the rotating sleeve 12, and at the same time drives the three locking blocks 7 to lock the outer wall of the connecting shaft 9. This avoids the need for operators to manually lock, effectively improves the work efficiency of operators, reduces the safety risk, and at the same time reduces the workload of operators while improving the accuracy of operation. By turning the hanger 4, the other end is disengaged from the inside of the second internal thread 16 to complete the disassembly. This facilitates the disassembly of the hanger 4 by the operator, effectively improves the practicality and flexibility of the equipment, and at the same time improves the disassembly efficiency of the hanger 4, facilitating the maintenance and repair of the hanger 4 by the operator.

[0035] Working principle: First, one end of the connecting shaft 9 with the first internal thread 10 is connected to an external device to complete the installation. Then, the mounting seat 1 is connected to the external device through the fixing bolts 2 on the three fixing blocks 3, and at the same time, the rotation of the output end of the motor 8 drives the rotation of the rotating gear 13, which in turn drives the rotation of the rotating sleeve 12. Then, the rotation of the rotating sleeve 12 drives the fixed rod 11 to rotate with the rotating sleeve 12, and at the same time drives the three locking blocks 7 to lock the outer wall of the connecting shaft 9. This avoids the need for operators to manually lock, effectively improves the work efficiency of operators. Then, the hanger 4 can be turned to disengage the other end from the inside of the second internal thread 16 to complete the disassembly.
