Referring to fig. 1 to 4, a buoy repair lifting tool includes a base 10, a jack 20, a fixing frame 30, and a lifting assembly 40. The jack 20 is provided on the base 10. The fixing frame 30 is disposed on the base 10. The lifting assembly 40 is liftably inserted on the fixing frame 30. The output of the jack 20 abuts against the lifting assembly 40. The lifting assembly 40 is used to support components that need to be removed.

It can be understood that after the lifting assembly 40 is pushed by the jack 20 to lift up and jack up the parts to be disassembled, the lifting assembly 40 can be fixed in position to release the pressure of the jack 20, the lifting assembly 40 is used for replacing the parts to be disassembled for supporting the jack, the jack 20 is prevented from being damaged by long-time compression, the safety in lifting work is further improved, the safety risk is reduced, and the life safety of workers is guaranteed.

Referring to fig. 1 and 2, the elevation assembly 40 includes a screw 41, an adjusting nut 42, and a support plate 43. The screw 41 is inserted into the holder 30. The adjusting nut 42 is screwed on the screw 41 and abuts against the fixing frame 30. Turning the adjusting nut 42 adjusts the relative height of the screw 41 and the fixing frame 30. The support plate 43 is provided on the screw 41. The support plate 43 is used for supporting components to be disassembled. The output end of the jack 20 abuts under the support plate 43.

It will be appreciated that when the supporting plate 43 is driven by the jack 20 to lift up the components, the adjusting nut 42 is rotated, so that the lower end surface of the adjusting nut 42 abuts against the fixing frame 30, and then the jack 20 can be decompressed, and the lifting assembly 40 is used to replace the jack 20 to support the components.

Referring to fig. 1 to 3, the lifting assembly 40 further includes a fixing block 44, the fixing block 44 is detachably disposed on the supporting plate 43, and the fixing block 44 is used for fixing the special-shaped component.

It should be noted that, when the parts to be supported and disassembled are cylindrical or have other shapes, the flat plate has no stable supporting parts, so the fixing blocks 44 are used for fixing the parts.

Referring to fig. 3, the fixing block 44 is provided with a V-shaped groove 441.

It will be appreciated that in some embodiments of the utility model, cylindrical components may be received by the V-shaped groove 441 so as to be secured in the V-shaped groove 441 under the force of gravity.

Referring to fig. 1 to 4, the pressure test piece 50 is further included, and the pressure test piece 50 is provided on the base 10 for testing the overall lifting weight, avoiding exceeding the maximum lifting weight of the jack 20.

Referring to fig. 2, a display screen 51 is provided on the pressure test piece 50, and the display screen 51 may display pressure data in real time.

It will be appreciated that the failure of the jack 20 is often due to the fact that in use, the load-bearing weight exceeds the rated maximum load bearing, and after many times, failure occurs. Therefore, in order to avoid exceeding the load of the jack 20, the load bearing is detected through the pressure test piece 50, and then feedback is carried out through the display screen 51 to the constructor, so that improper operation is avoided.

Referring to fig. 2, the pressure test piece 50 is further provided with an alarm device 52, and when the data measured by the pressure test piece 50 exceeds 95% of the rated maximum lifting load of the jack 20, the alarm device 52 gives an alarm.

It should be noted that, in order to alert the constructor, in some embodiments of the present utility model, when the load capacity measured by the pressure test piece 50 exceeds 95% of the rated maximum load, the alarm device 52 sends an audible and visual alarm to alert the constructor to replace the jack 20 with a larger load.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
