Description
Technical Field
The utility model relates to a technical field that the nut was demolishd especially relates to a hydraulic nut demolishs device under water.
Background
Because the screw thread has the assembly easily and the detachability, by the wide application in each field of national economy construction, but bolt looseness is the biggest problem that faces in the threaded connection, the locking measure that takes at present is that use locking devices such as gasket increase frictional force.
The use of the anti-loosening device can cause great loss of the pretightening force, and the loss of the pretightening force increases the possibility of loosening the bolt, so that the anti-loosening device can be omitted under certain conditions. Under the condition that the bolt bears the axial load, when the clamping length of the bolt of 8.8 grades and above is larger than 3 times of the diameter of the thread, if the pretightening force can be accurately controlled, even if the bolt bears the impact load, enough residual pretightening force can be generally ensured to prevent the bolt connection from loosening.
In order to increase the rigidity, tightness and anti-loosening capability of threaded connection and prevent sliding of transverse load bolt connection, most threaded connections are required to be pre-tightened during assembly, the pre-tightening force needs to be determined according to the size of a bolt group and the working requirement of connection, and the pre-tightening force of a threaded connection piece after being screwed is generally required to be not more than 80% of the material yield strength of the threaded connection piece. Taking an 8.8-grade bolt of M72 as an example, the recommended torque is 12642Nm, the pre-tightening torque value is 10113.6Nm, the loosening torque value is generally 1.5-2.5 times of the pre-tightening torque, and if the intermediate value is 2 times, 20227.2Nm is needed if the bolt needs to be removed.
In actual operation, a hydraulic wrench or a hydraulic tensioner is generally adopted to install the bolt, and the aim of controlling the pretightening force is achieved. However, in the bolt dismantling process, as the torque required for loosening the bolt is far larger than that required for installing the bolt, the range of the capacity of the original installation tool can be exceeded, and the difficulty is brought to the dismantling work, which is more obvious in the underwater operation process. Because the divers are limited by the underwater environment, underwater operation is not as flexible and convenient as water operation, and generally, at most two divers work in cooperation, if a hydraulic wrench or a hydraulic stretcher cannot loosen bolts, the progress of a project can be directly influenced; in the case of a rare event, the bolt removal may be required using surface aids such as winches, with an uncontrolled risk.
