Description

Technical Field

[0001] The utility model relates to the field of propellers, in particular to a lifting device for a submersible propeller. Background Art

[0002] The working environment of the submersible propeller is underwater, and the pH value of the water quality is between 5 and 9, and it may exceed this value for a short time, and the water quality has certain corrosiveness. When the submersible propeller works, it will push the water flow. The lifting device is connected to the sling on the propeller through a steel wire rope. The steel wire rope is flexibly connected to the sling. When the water flow flows, the steel wire rope rubs against the sling. After long-term wear of the steel wire rope and the sling, the steel wire rope may break. When the propeller fails or is under daily maintenance, it needs to be lifted to the water surface. At this time, if the connecting steel wire rope breaks, the propeller cannot be lifted, and the propelling function is paralyzed. For this reason, we propose a lifting device for a submersible propeller to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0025] Embodiment 1:

[0026] As shown in Figures 1-9 , the submersible agitator lifting device includes a lifting frame 9. The lifting frame 9 is connected to the lifting member 1 through a lifting rope 7. The lifting member 1 is connected to the agitator 12. The lifting member 1 includes a wedge joint 2 and a lifting ring 4. A wear part 5 is provided on the wedge joint 2. The lifting rope 7 passes through the wear part 5 and is installed on the lifting member 1. With this structure, one end of the lifting rope 7 sequentially passes through the barrel pressing device 3, the wear part 5, the limiting rod 207 and the third through hole 602. After the lifting rope 7 abuts against the third through hole 602, one end of the lifting rope 7 is connected to the fastener 6 by welding. The lifting ring 4 is connected to the wedge joint 2 through a connecting bolt 8. The lifting ring 4 is connected to the second threaded hole on the agitator 12, so that the lifting member 1 is connected to the agitator 12. The wear part 5 is placed on the annular groove 206. The barrel pressing device 3 is installed on the wedge joint 2, and the annular plate 303 abuts against the wear part 5.

[0027] When the agitator works, the water flows. After long-term wear of the lifting rope 7 and the wear part 5, the thickness of the annular body 501 is smaller than the diameter of the lifting rope 7. Before the lifting rope 7 wears and breaks, the annular body 501 wears and breaks, and the identification ball 502 escapes from the annular body 501 and floats to the water surface. The staff observes whether the wear part 5 is worn through the identification ball 502. If the staff observes the identification ball 502, it means that the lifting rope 7 is about to break. The agitator 12 is lifted through the lifting frame 9 to replace the lifting rope 7, avoiding the phenomenon that the agitation function is in a paralyzed state.

[0028] After lifting the agitator 12, rotate the fastener 6 to make the fastener 6 drive one end of the lifting rope 7 to protrude from the wedge joint 2, cut off the lifting rope 7, rotate the barrel pressing device 3 to make the barrel pressing device 3 away from the wedge joint 2. After replacing the wear part 5, reinstall the lifting rope 7 on the wedge joint 2 and weld the fastener 6 and the lifting rope 7 together again, so that the whole device can be reused.

[0029] In a preferred embodiment, the wedge joint 2 includes a hollow sleeve 201. Connecting plates 204 are provided on both sides of the sleeve 201. An internal thread 202 is provided at the top of the sleeve 201. A through threaded hole 203 is provided on the sleeve 201. A limiting rod 207 is provided inside the sleeve 201.

[0031] In a preferred embodiment, a pressing barrel 3 is provided at the top of the wedge joint 2. The pressing barrel 3 includes a barrel body 301 with a hole in the middle. A rounded corner 302 is provided at the top of the barrel body 301. A ring plate 303 is provided at the bottom of the barrel body 301. The ring plate 303 abuts against the wear part 5. An external thread is provided on the barrel body 301. The barrel body 301 is connected to the internal thread 202. With this structure, the pressing barrel 3 is rotated so that the ring plate 303 abuts against the wear part 5 to ensure the stability of the wear part 5. The rounded corner 302 prevents the lifting rope 7 from contacting the pressing barrel 3 when it sways.

[0032] In a preferred embodiment, a hanging plate 401 is provided on the hanging ring 4. A second through hole 402 is provided on the hanging plate 401. The connecting bolt 8 passes through the through hole 205 and the second through hole 402. The connecting bolt 8 is installed on the connecting plate 204 through a nut. The hanging ring 4 is connected to the agitator 12. With this structure, the hanging ring 4 is located between the two connecting plates 204. The hanging ring 4 is connected to the wedge joint 2 through the connecting bolt 8. The connecting bolt 8 is installed on the connecting plate 204 through a nut to firmly connect the lifting member 1 and the agitator 12.

[0033] In a preferred embodiment, a fastener 6 is provided on one side of the wedge joint 2. The fastener 6 includes a bolt 601. The bolt 601 is connected to the threaded hole 203. A third through hole 602 is provided on the bolt 601. The lifting rope 7 sequentially passes through the pressing barrel 3, the wear part 5, the vertical hole 208 and the third through hole 602. One end of the lifting rope 7 is installed on the fastener 6. With this structure,

[0034] In a preferred embodiment, the wear part 5 includes a hollow ring body 501. A plurality of identification balls 502 are provided inside the ring body 501. The density of the identification balls 502 is less than the density of water. The hardness of the ring body 501 is less than the hardness of the lifting rope 7. With this structure, the identification balls 502 are colored floating balls, which is convenient for the staff to observe whether the wear part 5 is broken. The hardness of the ring body 501 is less than the hardness of the lifting rope 7, so that when the lifting rope 7 is in contact with the ring body 501 for a long time and wears, the ring body 501 will break before the lifting rope 7 breaks.

[0035] In a preferred embodiment, a bottom support base 10 is provided at the bottom of the agitator 12. The bottom support base 10 is installed on the pool wall 11.
