Abstract
Description
Technical Field
[0001] The invention relates to the technical field of chain equipment, in particular to a high-strength welding chain with good fastening degree. Background Art
[0002] Welded chain is made of steel bent into an oval ring, and then welded by forging or electric welding. After the welded chain is made, it needs to be heat treated to ensure the strength and surface hardness of the chain. The material of ordinary chain is No. 20 steel, and the material of high-strength chain is alloy steel. Marine welded anchor chain is often manufactured by flash butt welding. Welded chain is widely used in heavy-duty transport vehicles such as containers, trucks and containers. It can be used to fix goods to ensure safety and stability during transportation. It can also be used for loading and unloading goods to improve work efficiency.
[0003] During the use of traditional welded chains, especially at the joints of the chain links, the stress state is extremely uneven, and local areas of the contact surface will be damaged, which will seriously affect the service life of the chain. Summary of the invention
[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a high-strength welded chain with good fastening, which solves the problem that during use of traditional welded chains, especially at the joints of the chain links, the stress state is extremely uneven, local areas of the contact surface may be damaged, and the service life of the chain may be seriously affected.
[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-strength welded chain with good fastening, including a link body, wherein a buffer structure is arranged inside the link body and near both sides, the buffer structure includes a plurality of hydraulic chambers, and the plurality of hydraulic chambers are distributed in a curved array along the bending position of the link body, and two adjacent hydraulic chambers are connected by a pressure transmission channel, and the side walls of the plurality of hydraulic chambers near the inner wall of the link body are connected with a connecting channel, and the end of the connecting channel away from the hydraulic chamber is connected to the inner wall of the link body, and a pressure transmission slide is arranged inside the connecting channel, and a return spring is fixedly connected to the side wall of the pressure transmission slide away from the hydraulic chamber, and the end of the return spring away from the pressure transmission slide extends to the interior of the link body and is fixedly connected to a circular connecting block.
[0006] Preferably, reinforcing ribs are arranged inside the chain link body.
[0007] Preferably, a pressure-relief chamber is provided inside the two straight sides of the chain link body, and the pressure-relief chamber is connected to the hydraulic chambers on both sides through a pressure-dividing channel. Two pressure-relief slides are provided inside the pressure-relief chamber, and a plurality of pressure-relief springs are provided between the two pressure-relief slides.
[0008] Working principle: When in use, when the chain links are subjected to relative movement due to tension, the circular connecting blocks in the local area will transfer the pressure to its pressure transmission slide plate, and the hydraulic oil inside the pressure transmission slide plate will be transferred to other pressure transmission slide plates, thereby realizing pressure sharing, and playing a good protective role on the connection. When the pressure is too large, it will also be transferred to the pressure relief cavity through the pressure distribution channel, and the secondary absorption of pressure will be achieved through the pressure relief spring and the pressure relief slide plate, thereby further protecting the chain link body.
[0009] (III) Beneficial effects The present invention provides a high-strength welding chain with good fastening properties. It has the following beneficial effects: 1. When the chain links of this high-strength welded chain with good tightness are subjected to relative movement under tension, the circular connecting blocks in the local area will transfer the pressure to the pressure-transmitting slide plate. The hydraulic oil inside the pressure-transmitting slide plate will be transferred to other pressure-transmitting slide plates, thereby realizing pressure sharing and providing good protection for the connection.
[0010] 2. When the pressure is too high, the high-strength welded chain with good tightness will also transfer the pressure to the inside of the pressure relief cavity through the pressure-dividing channel, and realize secondary absorption of the pressure through the pressure relief spring and the pressure relief slide plate, thereby further protecting the chain link body.
