In the process, as shown in fig. 10, during the process of extending the lifting hydraulic cylinder 101, the right-angle locking plate 9 is driven to transversely move, and the locking clamp 903 is lifted and sprung under the slope of the driving locking teeth 10; when the lifting hydraulic cylinder 101 has faults such as pressure loss and the like due to the damage of the sealing of the internal piston, the locking clamping plate 903 can be reversely clamped on the vertical surface of the driving locking tooth 10, so that the situation that the lifting hydraulic cylinder 101 is extruded and retracted to cause the blowout preventer to fall is avoided;
when the lifting hook 701 is lowered, the micro hydraulic cylinder 911 is controlled to retract through hydraulic pressure, so that the micro hydraulic cylinder 911 drives the rectangular frame plate 908 and the locking clamping plate 903 to move downwards through the shaft end pulling disc 910, the locking clamping plate 903 does not interfere with the driving locking teeth 10 after moving downwards, and then the lifting hydraulic cylinder 101 is controlled to retract, so that the lifting hook 701 is gradually lowered.
In the lifting process, the locking clamping plate 903 is in an up-down moving state when being guided by the slope of the driving locking tooth 10, the pressurizing plug tray 917 is fixed with the locking clamping plate 903 through the synchronous rib plate 914 and the connecting shaft tube 915, and is driven to move up and down, when the pressurizing plug tray 917 moves down, air flow at the lower part of the pressurizing plug tray 917 flows to the lower part of the layering separating tray 918 through the separating tray one-way valve 920 under extrusion, and when the pressurizing plug tray 917 moves up, negative pressure is generated at the lower part of the pressurizing plug tray 917, so that air flow in the external environment is re-inhaled through the plug tray one-way valve 919, high-pressure air flow generated by the pressurizing plug tray 917 is circularly reciprocated and conveyed into the annular air cavity 927 through the air channel conveying tube 925, the air channel 929 is obliquely sprayed downwards, at the moment, the lifting steel rope 7 moves up in the inside of the steel rope through hole 928, and the air flow can clean the surface of the lifting steel rope 7, and remove sand and dust; and since the pressurizing stopper 917 is reciprocally and impulsively moved, the air flow outputted from the inclined air tank 929 is also in an impulsive fluctuation state, so that the cleaning ability is improved.
When the lifting hydraulic cylinder 101 stretches out faster, and the right-angle locking plate 9 moves faster, the driving locking teeth 10 can move fast relative to the locking clamp 903, at this time, the pressurizing plug disc 917 moves up and down quickly in a short time to generate more air flow, the air flow is not discharged through the inclined air groove 929, the air pressure in the cylinder cavity 916 can be raised, at this time, the buffering pressure storage plug disc 922 moves elastically downwards, the high pressure can be alleviated, the air pressure in the cylinder cavity 916 is maintained to be stable, the high pressure in the cylinder cavity 916 is reduced, and the damage probability of parts such as edge sealing parts of the pressurizing plug disc 917 is reduced.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
