Detailed Implementation
[0023] 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.
[0024] Please see Figures 1-6 This utility model provides a technical solution: a hydraulic anchor winch with reliable braking, including a mounting frame 1. Two mounting plates 2 are fixedly connected to the upper surface of the mounting frame 1. A shaft 3 is rotatably connected between the two mounting plates 2. A drum 4 is fixedly sleeved on the outside of the shaft 3. A hydraulic motor 5 is fixedly connected to the surface of the left mounting plate 2. The output shaft of the hydraulic motor 5 is connected to the shaft 3 via a reduction mechanism. Two brake discs 6 are fixedly sleeved on the outside of the shaft 3. A first brake band 7 is on the outside of the brake discs 6. Two brake plates 8 are provided on the outside of the brake discs 6. A second brake band 9 is provided on the inside of the brake plates 8. Mounting grooves 10 are provided on both sides of the brake discs 6. Mounting rings 11 are provided inside the mounting grooves 10. A first locking tooth 12 is fixedly connected to the surface of the mounting ring 11. A second locking tooth 13 is provided on the inside of the brake plate 8. The first locking tooth 12 and the second locking tooth 13 are compatible with each other. A drive assembly is provided on the upper surface of the mounting frame 1.
[0025] The drive assembly includes a fixed plate 14, with a guide groove 15 on the upper surface of the fixed plate 14. A bidirectional threaded rod 16 is rotatably connected inside the guide groove 15. The front end of the bidirectional threaded rod 16 rotatably passes through the interior of the fixed plate 14. A crank handle is also matched to the front end of the bidirectional threaded rod 16. Two brake plates 8 are slidably connected inside the guide groove 15. The two brake plates 8 are respectively threaded onto two opposite threads of the bidirectional threaded rod 16.
[0026] The inner wall of the brake plate 8 has two arc-shaped grooves 17, and a sliding plate 18 is slidably connected inside the two arc-shaped grooves 17. The second locking tooth 13 is fixedly connected to the surface of the sliding plate 18. Limiting grooves 19 are provided on both sides of the inner wall of the arc-shaped grooves 17.
[0027] Both ends of the sliding plate 18 are provided with relief grooves 21, and the inner wall of the relief grooves 21 is provided with sliding grooves 22. Two drive plates 23 are slidably connected inside the sliding grooves 22, and positioning rods 24 are fixedly connected to the opposite side surfaces of the two drive plates 23.
[0028] The positioning rod 24 slides through the interior of the sliding plate 18 and is slidably connected to the interior of the limiting groove 19.
[0029] Three fixed rods 25 are fixedly connected inside the sliding groove 22. Two drive plates 23 are slidably sleeved on the outside of the three fixed rods 25. A return spring 26 is fixedly connected between the two drive plates 23. The return spring 26 is movably sleeved on the outside of the fixed rods 25. When the operator presses the two drive plates 23 towards the middle, the drive plates 23 will drive the positioning rod 24 to move, thereby causing the positioning rod 24 to disengage from the inside of the limiting groove 19, which facilitates the disassembly of the sliding plate 18 and the replacement of the second locking tooth 13.
[0030] The mounting ring 11 has a mounting screw 27 inside, which makes it easy to install the mounting ring 11 inside the mounting groove 10.
[0031] Two support grooves 28 are provided on the adjacent side surfaces of the two mounting plates 2. A connecting plate 20 is slidably connected inside the two support grooves 28. The two connecting plates 20 are fixedly connected to the two brake plates 8. The stability of the brake plates 8 is further ensured by the cooperation between the support grooves 28 and the connecting plates 20.
[0032] Working principle:
[0033] When the hydraulic anchor winch with reliable braking is in use, and braking of the drum 4 is required, the hydraulic motor 5 can be used to achieve initial braking. Subsequently, the operator can use the handle of the double-threaded rod 16 to rotate the double-threaded rod 16. The rotation of the double-threaded rod 16 can drive the two brake plates 8 to move. When the two brake plates 8 move, the first brake band 7 and the second brake band 9 first come into contact, which can improve the braking effect. The first locking tooth 12 and the second locking tooth 13 will come into contact. When the inclined surfaces of the first locking tooth 12 and the second locking tooth 13 come into contact, the second locking tooth 13 will force the sliding plate 18 to slide inside the arc groove 17, thereby realizing the fine adjustment of the position between the locking teeth until the first locking tooth 12 and the second locking tooth 13 are fully engaged. At this time, the braking effect on the brake disc 6 can be further improved.
[0034] When the first locking tooth 12 and the second locking tooth 13 need to be replaced, the two drive plates 23 are first pressed together. At this time, the drive plates 23 will drive the positioning rod 24 to move, thereby causing the positioning rod 24 to disengage from the inside of the limiting groove 19, which makes it easier to disassemble the sliding plate 18 and replace the second locking tooth 13. Subsequently, the first locking tooth 12 can be replaced by using the mounting screw 27, thus ensuring the braking effect.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
