Function and use of eyebolts
The eyebolt is a bolt with a ring at the head, which ensures that the load of the rotating eyebolt is such that a part of the ring does not break and that the part of the ring does not deform. While other bolts are fastened with special tools, eyebolts are installed by inserting a rod into the ring part.
In addition, eyebolts are two general threaded parts that are called one foot in length in addition to the general product of longer eyebolts, other bolts and do not have the nominal length of a very similar poorly threaded part. This is not the one that is the threaded part of the eye bolt, the purpose of which is to conclude a member like any other bolt, this is because it is the member that is fixed below so that the wire or chain is hooked to the part of the ring, and this is the function that the eyebolt itself has.
When the user uses the eyebolt, as an application of the eyebolt, hooks and ropes, etc. can be suspended and lifted on the hole part. One of our more common uses is to mount eyebolts on the top surface of equipment that cannot be lifted by a person such as a sleeve and lifted from above. Alternatively, the product can be mounted on the side part of a component to attach a chain, etc. to the eyebolt. The eyebolts are not used for hanging objects, but for connecting chains, etc. When used in lifting and hoisting, the eyebolts are used together with other lifting slings to solve the hoisting work well.
How is the position of eyebolts arranged?
The eyebolt similar product, the eyebolt is generally installed in the top center of the parts or symmetrical arrangement, used for lifting, can also be symmetrical arrangement on both sides, the design should pay attention to its safety load enough to lift the whole parts;
The open cover screw should be a kind of jacking screw, is used to disassemble, generally a set of screws, but longer than other screws, other screws are all loose, the screw tightening, parts such as cover from the original position out; positioning pin is used for positioning, generally to ensure that the key position alignment and the arrangement of the pin, generally can be arranged to avoid the quarter position and other fastening bolts under more serious force area, and the pinhole is not made through the hole, the pin should consider whether there is a demolition requirement.
oil level indicator is arranged in the vertical direction, the lowest place should be no less than 10%~15% of the height of the oil cabinet; the oil plug is for oil injection or oil discharge, arranged in the area with no important influence on the structure.
The observation hole depends on what the specific purpose is; the ventilation cap is arranged at the top of the oil cabinet, the aperture is larger than the oil inlet pipe, and the end should make an elbow type to avoid falling into the debris.
Is the material strength level the key to determining the strength of the eyebolt?
The eyebolt is a type of fastener, which is small in size but very common. It is connected and fastened by the bolt and the lifted object to achieve the purpose of smooth lifting and easy lifting of heavy objects, whether it is wind powerlifting or ordinary board room lifting, the strength level of the eyebolt and bolt parts are demanding.
Is the material strength grade the key to judging the strength of the eyebolt?
From the surface, we cannot distinguish the quality of eyebolts, but we can judge from the material strength grade. The core difference between high-strength bolts and ordinary bolts does not lie in the strength of the material used, but in the form of the force applied. The essence is whether to apply preload and use static friction to resist shear. However, due to the difference in international norms, the American standard and the national standard are different, so the material strength is not the key to distinguishing high strength bolts from ordinary bolts.
As for the high-strength eyebolt, where does its "high" mainly lie? The strength of high-strength bolts does not lie in the design value of its own bearing capacity, but in the stiffness of its design nodes, high safety performance, and strong resistance to damage.
In addition, an ultra-high-strength eyebolt not only wins in terms of material but also in terms of weight reduction, by optimizing the function and volume of the connected parts, reducing their own weight, reducing their own size and increasing the installation control, which is more suitable for aircraft, wind power and other models.YIPENG holds to the principle of "quality is life, reputation is base", providing customers with high-quality products and satisfactory service.
