DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] See also Figures 1 to 5The utility model provides a technical solution: a hydraulic blowout preventer hoisting device, including a main frame support 1, an outer plate 2, a middle plate 3 and an inner plate 4 are installed inside the main frame support 1, an outer pulley gear set 5 and an outer turbine reduction set 6 are installed between the outer plate 2 and the middle plate 3 of the main frame support 1, and both ends of the outer pulley gear set 5 and the outer turbine reduction set 6 close to the inner side of the main frame support 1 are installed with mutually meshing gears, wherein the gears at both ends of the outer pulley gear set 5 are larger than the gears at both ends of the outer turbine reduction set 6, thereby playing a role in reducing speed and increasing torque, an outer hydraulic motor 7 is installed on one side of the outer plate 2, and an outer turbine driven by the outer hydraulic motor 7 is installed between the outer plate 2 and the middle plate 3. Rod 8, a turbine is installed in the middle position of the outer turbine reduction group 6, and the outer turbine rod 8 is installed with a worm gear meshing with the turbine. The worm gear transmission can not only reduce the speed and increase the torque, but also play a self-locking role to prevent overturning. The main engine bracket 1 is installed with an inner pulley gear group 9 and an inner turbine reduction group 10 between the middle plate 3 and the inner plate 4, an inner hydraulic motor 11 is installed on one side of the inner plate 4, and an inner turbine rod 12 driven by the inner hydraulic motor 11 is installed between the inner plate 4 and the middle plate 3. A running mechanism 13 and a guide wheel 14 are installed above the main engine bracket 1, and both ends of the outer pulley gear group 5, both ends of the inner pulley gear group 9 and the bottom of the main engine bracket 1 near the guide wheel 14 are all installed A pulley block 15 is installed, and a wire rope 16 is arranged between the pulley blocks 15. All the pulley blocks 15 in the main view are arranged in a straight line, wherein the two ends of the pulley block 15 below the guide wheel 14 are two pulleys, and the two ends of the outer pulley gear block 5 and the inner pulley gear block 9 are a pulley and are staggered in the top view but aligned one by one with the pulleys of the pulley block 15 below the guide wheel 14. The wire rope 16 passes over the above pulley blocks 15 and hangs down from the position of the inner pulley gear block 9. When the inner hydraulic motor 11 and the outer hydraulic motor 7 are working, both can provide pulling force for the wire rope 16 to lift up. A balance beam 17 is suspended below the wire rope 16. The operating mechanism 13, the inner hydraulic motor 11 and the outer hydraulic motor 7 are The inner and outer hydraulic motors 7 are connected to a hydraulic system 18 through oil pipes. The hydraulic system 18 provides the operating mechanism 13, the inner hydraulic motor 11 and the outer hydraulic motor 7 with high-pressure oil required for operation. When the operating mechanism 13 is in operation, the lifting device is driven to travel on the guide rail. When the inner hydraulic motor 11 is in operation, the inner turbine rod 12 is driven to rotate. When the outer hydraulic motor 7 is in operation, the outer turbine rod 8 is driven to rotate. The two sets of lifting devices form a lifting combination. The balance beams 17 under the two sets of lifting devices are respectively clamped on both sides of the hydraulic blowout preventer. When the two sets of lifting devices are working at the same time, the hydraulic blowout preventer is synchronously lifted or lowered. When a single lifting device is working, the inclination angle of the hydraulic blowout preventer can be changed to correct the posture.
[0024] When in use, first hang the hoisting device upside down under the two parallel guide rails through the operating mechanism 13, and then the hydraulic system 18 works to provide high-pressure oil to the operating mechanism 13. When the operating mechanism 13 is running, it drives the hoisting device to move under the guide rail to just above the hydraulic blowout preventer, and then the inner hydraulic motor and the outer hydraulic motor work at the same time to quickly lower the balance beam 17, and then the two balance beams 17 are respectively clamped on both sides of the hydraulic blowout preventer, and then the inner hydraulic motor and the outer hydraulic motor work at the same time to slowly pull the balance beam 17 up. In this process, since the hydraulic motor is used as the power mechanism, it can provide a very large torque to the turbine rod, and then the turbine rod drives the turbine reduction group to rotate through the meshing relationship with the turbine. Since it is a worm gear transmission, it can not only reduce speed and increase torque but also To avoid reversal, the lifting device does not need a brake device and can be self-locked by the worm gear. The turbine reduction group drives the large gear of the pulley gear group to rotate through the small gear, which further reduces the speed and increases the torque. After two reductions, the large torque hydraulic motor finally makes the pulleys installed at both ends of the pulley gear group have a very large torque, thereby greatly improving the explosive force and realizing the lifting of a very heavy hydraulic blowout preventer. Since the main transmission mechanism, the pulley gear group and the turbine reduction group are hidden in the main frame bracket 1, the internal structure is compact. The power is provided by the hydraulic motor, which is not only small in size but also strong in power, so that the lifting device has a small size but strong explosive force. When the two sets of lifting devices work at the same time, the hydraulic blowout preventer is lifted or lowered synchronously. When a single lifting device is working, the inclination angle of the hydraulic blowout preventer can be changed to correct the posture.
[0025] In summary, the hydraulic blowout preventer hoisting device can greatly improve the torque through the pulley gear set, the turbine reduction group and the outer turbine rod 8, and the torque that can be provided by the hydraulic motor under the same volume is much greater than that of the electric motor, so that the hydraulic blowout preventer hoisting device has a strong explosive force and can lift the hydraulic blowout preventer with a large mass. The main transmission mechanism pulley gear set and the turbine reduction group are hidden inside through the box-type main frame bracket 1 to make the structure compact. The power provided by the hydraulic motor is not only small in size but also strong in power.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
