Description

Technical Field

[0001] This utility model relates to the field of winch technology, and in particular to a wind-resistant locking device for marine winches. Background Technology

[0002] A winch is a lifting device with strong pulling force. It mainly consists of a drum, transmission device, braking device and other components. The rotation of the drum winds a steel wire rope or chain to achieve the function of pulling or lifting heavy objects. In mines, it is used to hoist ore and personnel up and down the shaft; in the construction industry, it can assist in hoisting building materials; on ships, it can be used for towing operations, etc. It can be operated in various ways, including manual, electric or hydraulic drive. Different types of winches vary in terms of pulling force and adaptability to working environment. It is an indispensable and important piece of equipment in industrial, engineering and other fields.

[0003] However, in the current market, the most common devices usually use hydraulic cylinders to directly drive discs to limit and lock materials. But in actual applications, when encountering large winds that cause the ship to move, the existing devices reveal their limitations: because they cannot effectively lock the winch, the rotating column inside the winch is prone to movement. This situation not only affects the normal use of the device, but also hinders its widespread application. Therefore, it is urgent to design a marine winch anti-wind swing locking device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wind-resistant locking device for marine winches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind-resistant locking device for an ocean winch includes a base plate, a locking assembly on the top of the base plate, and a limit component inside the locking assembly.

[0007] The locking assembly includes a mounting base, inside which a rotating column is movably mounted via a bearing. The limiting assembly includes a rotating groove. An outer locking block is movably mounted on the inner side wall of the mounting base via a rotating shaft. An inner locking block is located at the center of the outer locking block on the mounting base. Connecting columns are provided between the inner locking blocks. A return spring is provided between the connecting columns. A piston cylinder is provided at one end adjacent to the inner locking block. The output shaft of the piston cylinder is connected to the inner locking block. The inner locking block is located inside the rotating groove, and the outer locking block is located on the outer wall of the rotating column.

[0008] Preferably, the locking assembly further includes a piston sleeve, a piston rod is slidably connected inside the piston sleeve, the piston sleeve is connected to the piston cylinder through a hose, and the opposite ends of the piston rod are fixed to one end of the outer locking block.

[0009] Preferably, the locking assembly further includes a hydraulic base, which is fixed to one outer wall of the mounting base by bolts.

[0010] Preferably, the hydraulic base has multiple telescopic cylinders installed inside by bolts, and the output end of the multiple telescopic cylinders is fitted with a piston plate by bolts. The outer wall of one side of the hydraulic base is connected to the piston cylinder by a pipe.

[0011] Preferably, a winding drum is bolted to the outer wall of the end of the rotating column away from the base plate, and the rotating column is located at the center of the outer wall of one side of the mounting base.

[0012] Preferably, the limiting component includes a mounting ring, which is fixed to the center of the inner wall of one side of the mounting base by bolts, and a locking buckle is installed on the inner wall of the mounting ring by bolts.

[0013] Preferably, a rotating rod is movably mounted on the outer wall of the rotating column located at the center of the mounting ring via a rotating shaft. A connecting seat is movably mounted on the outer wall of the rotating rod. A locking tongue is mounted on the outer wall of one end of the connecting seat via a bolt. A spring is fixedly connected to the inner wall of the top of one side of the connecting seat, and the other end of the spring is fixedly connected to the outer wall of the rotating column.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the locking component, when the multi-section telescopic cylinder is started, it can inject hydraulic oil into the piston cylinder. Under the action of hydraulic oil, the piston cylinder will push the inner blocks away from each other. At this time, the hydraulic oil in the piston cylinder will also be transported to the piston sleeve. During this process, the hydraulic oil will drive the piston rod to move apart, and the piston rod will drive the outer locking block to move accordingly. This device uses the simultaneous action of the inner and outer locking blocks to efficiently lock and fix the rotating column, prevent the rotating column from moving, and further enhance the practical value of the device.

[0016] 2. By setting a limiting component, when the winch stalls due to damage, causing the rotating column to rotate, the rotating column will drive the locking tongue to move due to centrifugal force. The locking tongue will then drive the connecting seat to move together. At this time, with the help of the rotating rod, the locking tongue can be locked onto the outer wall of the lock. In this way, the rotating column can be effectively limited and fixed to prevent it from rotating continuously due to damage. In addition, this structure can also protect the locking component and prevent the locking effect of the locking component from being affected by the rotating column stalling and rotating too fast.

A piston cylinder 25 is provided at one end adjacent to the inner locking block 22. The output shaft of the piston cylinder 25 is connected to the inner locking block 22. The inner locking block 22 is located inside the rotating groove 57, and the outer locking block 21 is located on the outer wall of the rotating column 3. When hydraulic oil is injected into the piston cylinder 25, the piston cylinder 25 will drive the inner locking blocks 22 to move away from each other.

The opposite ends of the piston rod 27 are fixed to one end of the outer locking block 21. When the piston cylinder 25 moves, the piston cylinder 25 can inject hydraulic oil into the piston sleeve 26 through the hose, so that the hydraulic oil inside the piston sleeve 26 can move the outer locking block 21, allowing the outer locking block 21 to lock the rotating column 3.

The rotating column 3 is located at the center of the outer wall of one side of the mounting base 211. When the winding drum 4 rotates, it can drive the rotating column 3 to rotate, thereby providing a position for the winding of the winch traction rope.

[0028] See Figure 3 and Figure 4The limiting component 5 includes a mounting ring 51, which is fixed to the center of the inner wall of one side of the mounting base 211 by bolts. A latch 52 is installed on the inner wall of the mounting ring 51 by bolts. The mounting ring 51 and the latch 52 are configured to help lock the rotating column 3.

A connecting seat 54 is movably mounted on the outer wall of the rotating rod 53. A locking tongue 56 is installed on the outer wall of one end of the connecting seat 54 by bolts. A spring 55 is fixedly connected to the inner wall of the top of one side of the connecting seat 54. The other end of the spring 55 is fixedly connected to the outer wall of the rotating column 3. When the rotating column 3 stalls, the rotating column 3 will use centrifugal force to move the locking tongue 56. The locking tongue 56 will drive the connecting seat 54 to move on the outer wall of the rotating rod and will drive the spring 55 to stretch, so that the locking tongue 56 will be locked on the outer wall of the latch 52.

[0029] The following are several preferred embodiments or application embodiments to help those skilled in the art better understand the technical content of this utility model and the technical contributions made by this utility model compared with the prior art:

[0030] Example 1

[0031] A wind-resistant locking device for an ocean winch includes a base plate 1, a locking assembly 2 on the top of the base plate 1, and a limit assembly 5 inside the locking assembly 2.

[0032] The locking assembly 2 includes a mounting base 211, inside which a rotating column 3 is movably mounted via a bearing. The limiting assembly 5 includes a rotating groove 57. An outer locking block 21 is movably mounted on the inner side wall of the mounting base 211 via a rotating shaft. An inner locking block 22 is located at the center of the outer locking block 21 on the mounting base 211. A connecting column 23 is arranged between the inner locking blocks 22, and a return spring 24 is arranged between the connecting columns 23. A piston cylinder 25 is arranged at one end adjacent to the inner locking block 22. The output shaft of the piston cylinder 25 is connected to the inner locking block 22. The inner locking block 22 is located inside the rotating groove 57, and the outer locking block 21 is located on the outer wall of the rotating column 3. When hydraulic oil is injected into the piston cylinder 25, the piston cylinder 25 will drive the inner locking blocks 22 to move away from each other. When the inner locking blocks 22 move away from each other, they will drive the connecting column 23 and the return spring 24 to move. By using the contact between the inner locking block 22 and the rotating column 3, the device can fix the rotating column 3.

[0033] The locking assembly 2 also includes a piston sleeve 26, with a piston rod 27 slidably connected inside. The piston sleeve 26 is connected to the piston cylinder 25 via a hose. The opposite end of the piston rod 27 is fixed to one end of the outer locking block 21. When the piston cylinder 25 moves, hydraulic oil can be injected into the piston sleeve 26 through the hose, allowing the hydraulic oil inside the piston sleeve 26 to move the outer locking block 21, thus locking the rotating column 3. The locking assembly 2 also includes a hydraulic seat 28, which is connected by bolts. Fixed to one side of the outer wall of the mounting base 211, the hydraulic base 28 provides power for the movement of hydraulic oil. A multi-section telescopic cylinder 29 is bolted inside the hydraulic base 28, and a piston plate 210 is bolted to the output end of the multi-section telescopic cylinder 29. A pipe connects the outer wall of one side of the hydraulic base 28 to the piston cylinder 25. When the multi-section telescopic cylinder 29 is activated, it drives the piston plate 210, which injects hydraulic oil into the piston cylinder 25, thus providing power for locking the rotating tube 3. The rotating column 3 is located away from the bottom. A winding drum 4 is bolted to the outer wall of one end of plate 1. A rotating column 3 is located at the center of one side of the outer wall of mounting base 211. When the winding drum 4 rotates, it drives the rotating column 3 to rotate, thus providing a position for the winding of the winch traction rope. The limiting assembly 5 includes a mounting ring 51, which is bolted to the center of one side of the inner wall of mounting base 211. A locking buckle 52 is bolted to the inner wall of the mounting ring 51. The mounting ring 51 and the locking buckle 52 are designed to lock the rotating column 3. The rotating column 3 is located at the center of the mounting ring 51. A rotating rod 53 is movably mounted on the outer wall via a rotating shaft. A connecting seat 54 is movably mounted on the outer wall of the rotating rod 53. A locking tongue 56 is bolted to the outer wall of one end of the connecting seat 54. A spring 55 is fixedly connected to the inner wall of the top of one side of the connecting seat 54. The other end of the spring 55 is fixedly connected to the outer wall of the rotating column 3. When the rotating column 3 stalls, the rotating column 3 will use centrifugal force to move the locking tongue 56. The locking tongue 56 will drive the connecting seat 54 to move on the outer wall of the rotating rod and will also drive the spring 55 to stretch, so that the locking tongue 56 will be locked onto the outer wall of the latch 52.

[0034] Working principle: In use, the multi-section telescopic cylinder 29 is first activated, which drives the piston plate 210 to move. The piston plate 210 injects hydraulic oil into the piston cylinder 25. The piston cylinder 25 drives the inner locking blocks 22 to move away from each other. When the inner locking blocks 22 move away from each other, they drive the connecting column 23 and the return spring 24 to move. With the inner locking blocks 22 and the rotating column 3 in contact, when the piston cylinder 25 moves, the piston cylinder 25 can inject the hydraulic oil inside into the piston sleeve 26 through the hose. The hydraulic oil inside the piston sleeve 26 can push the outer locking block 21 to move, so that the outer locking block 21 can lock the rotating column 3, thereby locking the device. In subsequent use of the device, when the rotating column 3 experiences stall rotation, the rotating column 3 will use centrifugal force to move the locking tongue 56. The locking tongue 56 will drive the connecting seat 54 to move on the outer wall of the rotating rod, and will drive the spring 55 to stretch, so that the locking tongue 56 will be engaged on the outer wall of the latch 52.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
