AI Technical Summary
In existing hydraulic oil storage and turnover devices, the friction between threaded connections is increased to prevent loosening, which leads to severe thread wear and subsequent stripping of the nut, thus failing to effectively prevent hydraulic oil leakage.
The design employs a nut limiting sleeve and a nut limiting plate to circumferentially limit the screw and nut, preventing relative rotation and thus avoiding loosening between the nut and nut, reducing thread wear.
It effectively prevents threads from loosening, extends the service life of screws and nuts, reduces thread wear, improves the anti-loosening effect, and avoids hydraulic oil leakage.

TECHNICAL FIELD
[0001] The utility model relates to hydraulic oil storage turnover device technical field, specifically is a kind of storage turnover device for hydraulic oil production. BACKGROUND
[0002] In the production process of hydraulic oil, the hydraulic oil needs to be stored and turned over, and the storage and turnover of the hydraulic oil is usually undertaken by a transport vehicle equipped with an oil tank, i.e., an oil tank truck.
[0003] In the prior art, the top end of the tank body of the oil tank truck is provided with a tank opening, through which hydraulic oil can be added to or extracted from the oil tank. During transportation, a tank cover is usually installed on the tank opening. The installation between the tank cover and the tank opening is carried out on the flange and screw cover of the tank opening, i.e., screw holes are formed on the flange and screw cover. After aligning the screw holes of the tank flange and the tank cover, a screw is passed through the screw holes, and then a nut is screwed. At the same time, a gasket is sleeved on the screw, and after the nut is tightened, the gasket is compressed. The gasket exerts a counterforce on the nut and the screw cap under its own elasticity. This counterforce generates a large pressure between the threads of the screw and the nut, thereby generating a large friction force, so as to prevent the loosening of the threaded connection and prevent the leakage of hydraulic oil from the tank opening.
[0004] However, in the prior art, the method of preventing the loosening of the threads and the leakage of hydraulic oil from the tank opening by increasing the friction between the threads is likely to increase the thread wear between the screw and the nut. When the wear reaches a certain degree, the thread surface becomes very smooth and the friction coefficient is greatly reduced, thereby causing the nut to slip and unable to be tightened. SUMMARY

When the nut 9 is tightened, the nut 9 is slightly adjusted in the tightening direction, so that one side edge of the nut 9 is parallel to the long plate of the rectangle formed by the slot body opening of the limiting plate mounting groove 16, and then one end of the nut limiting plate 10 is retracted from the limiting plate mounting groove 16. The screw cap 7 is inserted into the inner ring of the screw cap limiting sleeve 8, and the side surface of the end of the nut 9 extending out of the limiting plate mounting groove 16 abuts against the side wall of the nut 9, so that the screw cap limiting sleeve 8 limits the screw cap 7 in the circumferential direction and further limits the screw 6 in the circumferential direction. The nut limiting plate 10 limits the nut 9 in the circumferential direction. In the case that the screw 6 and the nut 9 are both limited in the circumferential direction, relative rotation cannot occur, and loosening cannot occur.
