Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship anchor equipment, in particular to a gap pad mechanism of a chain stopper of ship anchor equipment. Background Art
[0002] On a ship, the anchor equipment is an important equipment of the ship. The chain stopper is a necessary component of the anchor equipment and is an important equipment that every ship must have. The functions of the chain stopper are as follows: 1. When anchoring, it transmits the gripping force of the stressed anchor chain to the hull, so that the ship can resist the force of wind and waves and control the movement range of the ship; 2. When sailing, the chain stopper bears the weight of the anchor, relieves the force on the brake belt, and prevents the stressed anchor chain from sliding down.
[0003] Generally, when a new ship is launched, after the anchor is tightened against the anchor lip, the gap between the contact part of the chain stopper and the stressed anchor chain is relatively small when the chain stopper is lowered to work. Of course, there must be a gap. If there is no gap, the chain stopper will not be able to be lifted up due to excessive friction after it is lowered. During the operation of the ship, the equipment is constantly used, the stressed anchor chain ring is constantly worn, and the stressed part of the chain stopper contacting the stressed anchor chain is also constantly worn, and even deep grooves appear, resulting in a continuous increase in the gap between the chain stopper and the stressed anchor chain. The groove of the chain stopper changes the angle of the contact surface between the stressed anchor chain and the chain stopper, so that the stressed anchor chain has a large upward component of the reaction force on the chain stopper, causing the fixed pin of the chain stopper to bend and deform, and the chain stopper rises, and ultimately cannot prevent the stressed anchor chain from sliding down, causing the stressed anchor chain to fall into the sea during navigation, causing an anchor loss accident. In severe cases, it may also damage the ship or other secondary accidents such as the anchor claw hooking the submarine cable or oil pipeline or losing control and colliding with other ships.
[0004] The existing solution to the problem of increasing gaps is to weld iron blocks on the chain stopper, but this method has the following disadvantages: the chain stopper is relatively heavy and cannot be disassembled and transported to the welding room for welding during ship operation. Some types of ships, such as oil tankers, chemical tankers, LNG tankers, etc., cannot be welded anywhere other than the welding room on board. It is impossible to weld iron blocks. It is difficult to accurately control the size of the gap by welding iron blocks. The gap is too tight, and once the iron block rusts or deforms, the entire chain stopper may be unusable. After the stressed anchor chain or related parts are replaced, the gap changes, and the welded iron block may cause the chain stopper to be too long, pressing on the stressed anchor chain, making it unusable and difficult to remove. Grooves will appear on the welded parts after long-term use. The iron block welded on the chain stopper changes the structure and weight of the chain stopper, increasing the difficulty of manually operating the chain stopper. The welded iron block is locally subjected to greater pressure.
[0005] Therefore, in view of the deficiencies in the prior art, a gap spacer mechanism for a chain stopper of a ship anchor equipment is provided. Utility Model Content

[0011] The adjusting gasket is fixedly connected to an end surface of the cushion block body facing away from the chain stopper, and the adjusting gasket is located at an end close to the stressed anchor chain.
[0012] As a further improvement of the technical solution of the utility model, the locking part includes a connecting plate, a threaded handle and a nut. One end of the connecting rod is fixedly connected to the pad body, and the other end is fixedly connected to the nut.

[0033] Reference Figures 1 to 7 , a gap pad mechanism of a ship anchor equipment chain stopper 6, comprising a pad body 1, a limiter 2, a locking member 3 and an adjusting pad 4;
[0034] In one embodiment, referring to Figure 1-Figure 4 As shown, the pad mechanism is located on the contact surface between the chain stopper 6 and the stressed anchor chain 7, the limiter 2 is fixedly connected to the top of the pad body 1, and the pad body 1 is hung on the chain stopper 6 through the limiter 2; the locking member 3 is fixedly connected to both sides of the pad body 1, and the locking member 3 is connected to the top of the chain stopper 6; the adjusting gasket 4 is fixedly connected to the end face of the pad body 1 away from the chain stopper 6, and the adjusting gasket 4 is located at one end close to the stressed anchor chain 7.
[0035] The shortest distance between the chain stopper 6 and the stressed anchor chain 7 is measured, and an adjusting gasket 4 with appropriate thickness is selected according to the distance and fixedly connected to the pad body 1. The pad body 1 is hung on the chain stopper 6 through the limiter 2, and the locking member 3 is connected and fixed with the two sides of the chain stopper 6. When in use, the pad mechanism is placed between the chain stopper 6 and the stressed anchor chain 7 to reduce the distance between the gap between the contact surface of the chain stopper 6 and the stressed anchor chain 7 after the anchor is tightened. The stressed anchor chain 7 directly contacts the adjusting gasket 4 and the pad body 1. The adjusting gasket 4 directly contacts the stressed anchor chain 7 to replace the wear of the stressed part of the chain stopper 6 contacting the stressed anchor chain 7, so as to avoid the chain stopper 6 contacting the stressed anchor chain 7 to wear and form a groove, and prevent the groove from deepening and causing damage to the chain stopper 6. When the adjusting gasket 4 is worn out and even a deeper groove appears, the pad mechanism can be taken out, the adjusting gasket 4 can be cut off, and a new adjusting gasket 4 can be re-welded. The gap pad mechanism of the chain stopper 6 of the ship anchor equipment has the characteristic of avoiding the wear of the chain stopper 6 abutting against the stressed anchor chain 7. The pad mechanism can increase the contact area with the chain stopper 6, so that the local stress of the chain stopper 6 is changed to the overall large-area stress, and the pressure applied by the stressed anchor chain 7 on the chain stopper 6 is reduced, and the wear of the chain stopper 6 is avoided while improving the stress structure of the chain stopper 6, which plays a role in protecting the chain stopper 6. The pad body 1 and the adjustment pad are small in size and can be made of high-strength wear-resistant steel. Even if they are worn, they are easy to replace and the cost is low.
[0036] In one embodiment, referring to Figure 5 As shown, the locking member 3 includes a connecting plate 31, a threaded handle 32 and a nut 33. One end of the connecting rod is fixedly connected to the cushion block body 1, and the other end is fixedly connected to the nut 33. The threaded handle 32 is threadedly connected to the nut 33. The threaded handle 32 is screwed into the nut 33 and abuts against the top of the two side walls of the chain stopper 6. Preferably, the threaded handle 32 is T-shaped.
[0037] In one embodiment, the limiting part includes two iron blocks, which are fixedly connected above the pad body 1 and abut against the surface of the chain stopper 6. The pad mechanism also includes a handle 5, which is fixed above the pad and located between the two iron blocks.
[0038] In one embodiment, the thickness of the pad body 1 is greater than the thickness of the adjusting pad 4, and the thickness of the adjusting pad 4 is 2mm-30mm. The gap between the adjusting pad 4 and the stressed anchor chain 7 is 1mm-3mm. If it is less than 1mm, it is inconvenient to remove the pad.
[0039] In one embodiment, if the distance between the chain stopper 6 and the stressed anchor chain 7 is short, for example within 30 mm, only one pad body 1 can be made; if the distance exceeds 30 mm, the gap after installing the pad body 1 is less than 10 mm, and a 5 mm and a 2 mm adjusting gasket 4 are welded on the surface of the pad body 1 to control the gap within 1 mm-3 mm.
[0040] In one embodiment, if the chain stopper 6 is of the guillotine type, the length of the pad body 1 is approximately equal to the outer diameter width of the ordinary load-bearing anchor chain 7; some chain stoppers 6 are of the tongue type, the length of the pad body 1 is equal to the length of the front end of the chain stopper 6 plus twice the thickness of the pad mechanism, and the height of the pad is equal to the thickness of the front end of the chain stopper 6.
