Description

Technical Field

[0001] This utility model relates to winches, and more particularly to a winch internal motor mounting structure. Background Technology

[0002] Currently, Chinese patent CN120607200A discloses a marine winch, including a winch body. The winch body is equipped with a rope-laying mechanism for guiding the winding and unwinding of steel cables and a ring-sweeping mechanism for cleaning around the steel cables. The rope-laying mechanism is mounted on the winch body via a fixed frame and faces the steel cable rollers of the winch body. The ring-sweeping mechanism is mounted on the rope-laying mechanism and faces it. The rope-laying mechanism includes a guide wheel assembly and a reciprocating follower assembly. The reciprocating follower assembly is mounted on the fixed frame via a connecting plate, and the guide wheel assembly is slidably connected to the connecting plate. The ring-sweeping mechanism is mounted on the reciprocating follower assembly via an outer ring seat and is slidably connected to the guide wheel assembly. However, both the rope-laying mechanism and the ring-sweeping mechanism are independently located outside the steel cable rollers of the winch body, which increases the size of the marine winch and results in poor structural compactness. Utility Model Content

A receiving groove is provided at the center of the end of the steel cable roller, and the receiving groove is directly opposite the mounting opening. A connecting bracket is detachably connected to the fixed bracket. One end of the connecting bracket extends into the receiving groove to support the steel cable roller. The other end of the connecting bracket has a mounting groove at its center, which communicates with the mounting opening. A locking structure is housed in the mounting groove, and the output end of the locking structure passes through the connecting bracket and extends into the housing groove; A hydraulic motor, the output end of which is connected to the input end of the locking structure, wherein when the hydraulic motor is turned off, the locking structure clamps the output end of the hydraulic motor. The transmission structure has an input end connected to the output end of the locking structure, and the output end of the transmission structure passes through the steel cable roller and is rotatably connected to the fixed bracket. The steel cable roller is fixedly connected to the output end of the transmission structure.

[0005] With the above technical solution, when the hydraulic motor is turned on, it drives the steel cable roller to rotate through the transmission mechanism, thereby completing the winding and unwinding of the steel cable. When the hydraulic motor is turned off, the locking structure clamps the output end of the hydraulic motor, making it difficult for the steel cable roller to rotate. The transmission mechanism is located inside the steel cable roller, and the hydraulic motor is connected to the transmission mechanism through a connecting bracket. This structure occupies less space and has the advantage of good structural compactness.

[0006] Preferably, a positioning protrusion is provided on the inner wall of the steel cable roller, and a positioning ring groove is provided on the outer wall of the connecting bracket. The inner end of the positioning protrusion extends into the positioning ring groove to restrict the axial movement of the steel cable roller.

A retaining ring is disposed on the inner side of the locking sleeve, and the retaining ring abuts the static friction plate against the mating plate.

[0009] Through the above technical solution, when the hydraulic motor is turned on, it drives the locking connecting shaft to rotate, which in turn causes the mating plate to rotate relative to the static friction plate. When the hydraulic motor is turned off, the static friction plate will clamp the output end of the hydraulic motor through the mating plate. The engagement of transmission gear one and transmission gear two improves the transmission efficiency between the locking connecting shaft and the mating plate, while the engagement of limit gear one and limit gear two improves the transmission efficiency between the locking outer sleeve and the static friction plate.

[0016] Preferably, a support frame is provided at the lower inner end of the connecting bracket, a support plate is provided at the upper end of the support frame, and the hydraulic motor is abutted against the upper end of the support plate.

[0017] With the above technical solution, the support plate can be used to support the hydraulic motor, so that the position of the hydraulic motor is not easily externally connected, and the installation stability is higher.

[0018] Preferably, a mounting base is provided at the lower inner end of the connecting bracket; The support frame includes: The support plate is integrally formed and disposed on the lower inner side of the connecting bracket.
