Description

Technical Field

[0001] This utility model relates to the field of anchor chain technology, and more specifically, to a marine anchor chain turntable with a buffer mechanism. Background Technology

[0002] Anchor chains are an essential tool for ships. Due to their heavy weight, they require mechanical equipment, such as an anchor chain swivel, to raise and lower them. The swivel is often rotated in reverse to quickly release the chain. However, this rapid rotation can cause significant noise and vibration. Furthermore, when the chain is fully released, its inertia can strain the swivel, affecting its lifespan.

[0003] Chinese utility model patent application number 202120650188.X discloses a marine anchor chain turntable with a buffer mechanism. It is equipped with a buffer spring, which can buffer and protect the turntable when the anchor chain pulls the turntable with inertial force. However, when the anchor chain stops, the inertial force of the anchor chain on the turntable will still cause the turntable to be pressed down. When the inertial force is large, it can easily cause damage to the bearing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a marine anchor chain turntable with a buffer mechanism.

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

[0006] A marine anchor chain turntable with a buffer mechanism includes a connecting shaft with two limiting discs spaced apart at the middle position of the connecting shaft. The portion of the connecting shaft between the two limiting discs is a spindle, and a buffer pad is wrapped around the spindle. An outer disc is wrapped around the outside of the buffer pad, and the anchor chain slides on the outer disc. Bearings are installed at both ends of the connecting shaft, and a buffer mechanism is provided between each of the two bearings and the corresponding limiting disc. The bearings and the buffer mechanisms are fixed together on an external support.

[0007] The present invention is further configured such that: the inner side of the bearing and the connecting shaft are interference fit, the buffer mechanism is provided with an inner ring, and the inner ring and the connecting shaft are clearance fit.

[0008] The present invention is further configured such that: the buffer mechanism includes an outer ring, which is fixed on an external support; a buffer space exists between the inner ring and the outer ring; a plurality of connecting ears 1 are provided at the center of the outer side of the inner ring, which are evenly distributed along the circumference of the inner ring; a plurality of connecting ears 2 are correspondingly provided on the inner side of the outer ring, with two connecting ears 2 corresponding to one connecting ear 1; one connecting ear 1 and its two corresponding connecting ears 2 are located in the same radial plane of the connecting shaft; a hydraulic rod is rotatably connected to the connecting ear 2, and the output shaft of the hydraulic rod is rotatably connected to the corresponding connecting ear 1.

[0009] The present invention is further configured such that: a convex ring is provided at the top end of the output shaft of the hydraulic rod, and a buffer spring is sleeved on the output shaft of the hydraulic rod, with the two ends of the buffer spring respectively abutting against the convex ring and the cylinder body of the hydraulic rod.

[0010] The present invention is further configured such that the buffer pad is a rubber pad.

[0011] The present invention is further configured such that: a plurality of insert rods are evenly arranged on the outer disc, the insert rods extend radially along the mandrel, and the insert rods can be inserted into the anchor chain ring.

[0012] The advantages of this utility model are:

[0013] 1. An outer disc is set on the mandrel, and the outer disc is connected to the mandrel through a buffer pad. The buffer pad is a rubber pad. When the anchor chain suddenly stops moving, the tangential decomposition force of the inertial force of the outer disc causes the outer disc to continue to rotate. This part of the rotational force drives the buffer pad to twist, which is then converted into the internal energy of the buffer pad and consumed, reducing the direct impact on the turntable.

[0014] 2. A buffer mechanism is installed between the bearing of the connecting shaft and the limiting plate. The buffer mechanism and the connecting shaft are connected by a gap. During normal operation, the connecting shaft does not contact the buffer mechanism. When the turntable stops suddenly, the radial decomposition force of the anchor chain's inertial force on the outer plate causes the connecting shaft to tend to move downward. At this time, the connecting shaft is pressed down and comes into contact with the buffer mechanism. The force of the inner ring on the outer ring is dissipated through several hydraulic rods and buffer springs, thereby preventing the connecting shaft from continuing to move. This avoids excessive radial force on the bearing and reduces the risk of bearing damage. Attached Figure Description

[0023] Please see Figure 1-4 The first embodiment of this utility model is as follows:

[0024] A marine anchor chain turntable with a buffer mechanism includes a connecting shaft 1. Two limiting discs 2 are spaced apart at the middle position of the connecting shaft 1. The part of the connecting shaft 1 between the two limiting discs 2 is a core shaft 11. A buffer pad 3 is wrapped on the core shaft 11. An outer disc 4 is wrapped on the outside of the buffer pad 3. The buffer pad 3 is a rubber pad. The anchor chain slides on the outer disc 4. Bearings 6 are installed at both ends of the connecting shaft 1. A buffer mechanism 5 is provided between the two bearings 6 and the corresponding limiting discs 2. The bearings 6 and the buffer mechanism 5 are fixed together on an external support.

[0025] The inner side of the bearing 6 is interference-fitted with the connecting shaft 1, and the buffer mechanism 5 is provided with an inner ring 51, which is clearance-fitted with the connecting shaft 1.

[0026] The buffer mechanism 5 includes an outer ring 52, which is fixed on an external support. There is a buffer space between the inner ring 51 and the outer ring 52. Several connecting ears 1 511 are provided at the center of the outer side of the inner ring 51. The several connecting ears 1 511 are evenly distributed along the circumference of the inner ring 51. Several connecting ears 2 521 are provided on the inner side of the outer ring 52. Two connecting ears 2 521 correspond to one connecting ear 1 511. One connecting ear 1 511 and its two corresponding connecting ears 2 521 are located in the same radial plane of the connecting shaft 1. A hydraulic rod 53 is rotatably connected to the connecting ear 2 521. The output shaft of the hydraulic rod 53 is rotatably connected to the corresponding connecting ear 1 511.

[0027] A convex ring 54 is provided at the top of the output shaft of the hydraulic rod 53, and a buffer spring 55 is sleeved on the output shaft of the hydraulic rod 53. The two ends of the buffer spring 55 abut against the convex ring 54 and the cylinder body of the hydraulic rod 53, respectively.

[0028] Several insertion rods 41 are evenly arranged on the outer plate 4. The insertion rods 41 extend radially along the spindle 11 and can be inserted into the anchor chain ring.

[0029] Specifically, an outer disk 4 is provided on the spindle 11. The outer disk 4 is connected to the spindle 11 through a buffer pad 3. The buffer pad 3 is a rubber pad. When the anchor chain suddenly stops moving, the tangential decomposition force of the inertial force on the outer disk 4 causes the outer disk 4 to continue to rotate. This part of the rotational force drives the buffer pad 3 to twist, thereby converting it into the internal energy of the buffer pad 3 and consuming it, reducing the direct impact on the turntable.

[0030] A buffer mechanism 5 is provided between the bearing 6 of the connecting shaft 1 and the limiting plate 2. The buffer mechanism 5 and the connecting shaft 1 are connected by a gap. During normal operation, the connecting shaft 1 does not contact the buffer mechanism 5. When the turntable stops suddenly, the radial decomposition force of the inertial force of the anchor chain on the outer plate 4 causes the connecting shaft 1 to tend to move downward. At this time, the connecting shaft 1 is pressed down and comes into contact with the buffer mechanism 5. The force of the inner ring 51 on the outer ring 52 is dissipated through several hydraulic rods 53 and buffer springs 55, thereby preventing the connecting shaft 1 from continuing to move. This avoids excessive radial force on the bearing 6 and reduces the risk of damage to the bearing 6.
