DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 , the technical solution of the utility model is further explained:

[0022] like Figure 1-Figure 4 As shown, the utility model discloses a motor maintenance and turning hoisting device, comprising a hanging beam 1, on which a lifting ring 2 for lifting is arranged. That is, a hook on the lifting device is hung on the lifting ring as a lifting power source.

[0023] Specifically, Figure 1 As shown, the lifting beam 1 is provided with a lifting lug 3 for connecting the motor wing, and the lifting lug 3 is provided with a locking bolt for fastening the lifting lug 3 to the lifting beam 1. In other words, the lifting lug is configured with left and right adjustable lifting lugs to suit the flip lifting of B5 vertical motors of different widths and shapes, and a fastening bolt is provided above the lifting lug to lock the lifting lug after adjustment.

[0024] The lifting eye 3 is connected to the motor wing through the main lifting rope 4. That is to say, one end of the main lifting rope is connected to the lifting eye, and the other end of the main lifting rope is connected to the lifting ring on the motor wing through the lock 9 and the pull ring 10.

[0025] Specifically, Figure 1 and Figure 2As shown, the suspension beam 1 is provided with an adjusting member, and the two ends of the motor are provided with connecting members, and the connecting members are connected to the adjusting member, so as to adjust the motor in the vertical state or horizontal state to the horizontal state or vertical state under the drive of the adjusting member. That is to say, the adjusting member is connected to the two ends of the motor through the auxiliary sling and the connecting member, and the two auxiliary slings are driven by the adjusting member to loosen and tighten, so as to flip the motor as a whole, realize the change of the horizontal (or vertical) state of the motor, and increase the stability of the flipping device; overcome the small angle of the conventional sling and the difficulty of flipping the motor; solve the problem of complex operation of multiple suspension points and high labor intensity.

[0026] In some embodiments, Figure 2 As shown, the connecting member includes a sleeve 13, a group of bushings 12 are symmetrically arranged in the sleeve 13, a fastening bolt 11 for fastening the bushing 12 to the convex shaft at one end of the motor is penetrated on the sleeve 13, and a movable bushing is built in the bushing 12; one end of the sleeve 13 is connected to the adjusting member 7 through the auxiliary sling 5. In other words, a special sleeve is installed on the shaft extension and non-shaft extension at both ends of the motor; a pair of bushings are installed in the sleeve, and bushing fastening and adjustment bolts are respectively arranged at the upper and lower parts of the sleeve, and a matching handle is operated; and a bushing-type movable bushing is arranged, made of brass, the bushing and the inner wall of the bushing are tightly fitted, and fixed with a countersunk hexagon socket bolt to improve the stability of operation; the end of the sleeve is equipped with a universal lifting ring to reduce the overturning resistance.

[0027] Specifically, Figure 3 and Figure 4 As shown, the adjusting member 7 includes a first drum 19 and a second drum 20, and the first drum 19 and the second drum 20 are respectively connected to the two ends of the motor through the wound auxiliary sling 5, and one end of the first drum 19 is provided with a first rotating gear 14, and one end of the second drum 20 is provided with a second rotating gear 15 corresponding to the first rotating gear 14, and the first rotating gear 14 is meshed with the second rotating gear 15; that is, auxiliary slings are respectively wound on the first drum and the second drum, and the first rotating gear and the second rotating gear are installed on the same end of the first drum and the second drum, and the first rotating gear and the second rotating gear are externally meshed, and then when the first rotating gear rotates, it can drive the second rotating gear to rotate synchronously in the opposite direction, and the first rotating gear and the second rotating gear respectively drive the corresponding first drum and the second drum to rotate in the opposite direction, and the auxiliary slings wound on the first drum and the second drum are in a state of one loose and one tight, thereby driving one end of the two ends of the motor upward and the other end downward, and turning the motor from a horizontal state to a vertical state.

[0028] In some embodiments, Figure 3As shown, the first rotating gear 14 cooperates with the power member so that the first rotating gear and the second rotating gear rotate synchronously in opposite directions under the drive of the power member. That is to say, by manually pulling the power member, the power member can drive the first rotating gear to rotate synchronously.

[0029] The power member includes a driving gear 16 and a hand chain wheel 17. The driving gear 16 is coaxially arranged with the hand chain wheel 17. The driving gear 16 meshes with the sub-gear arranged on the first rotating gear 14. A hand chain is wound on the hand chain wheel 17. That is to say, by pulling the hand chain, the hand chain drives the hand chain wheel in the reel gear box to rotate, and the hand chain wheel drives the driving gear to start rotating. The driving gear synchronously drives the first rotating gear to rotate, and the second rotating gear also rotates synchronously under the drive of the first rotating gear. However, the second rotating gear and the first rotating gear are designed to be externally meshed, so the two gears rotate in opposite directions, and the two reels coaxial with the gears rotate in two different directions, so that the cable at the non-axial extension end of the motor is rolled up, and the cable at the axial extension end is released at the same time. The synchronous tightening and loosening process of the cable always keeps the motor in a stable flipping state.

[0030] In some embodiments, a ratchet mechanism is provided on the driving gear 16. That is, a ratchet 18 is coaxially provided on the driving gear 16, and the ratchet 18 rotates in a directional manner under the limiting action of a limiting handle on one side, and the driving gear 16 and the ratchet 18 rotate synchronously at the same time, and the self-locking function of the ratchet can only be used to flip in one direction during the flipping process of the motor, and the motor will not rotate in the opposite direction as a whole due to the change of the center of gravity, thereby improving the safety performance and control accuracy, and the ratchet has the automatic retraction function of the unidirectional intermittent motion mechanism to effectively increase the work efficiency.

[0031] That is to say, when the horizontal motor is flipped to the vertical state, the ratchet steering handle 8 is rotated to the upright position, and the hand chain is pulled. The hand chain drives the hand chain wheel in the drum gear box to rotate, and the hand chain wheel drives the driving gear to start rotating. The driving gear synchronously drives the first rotating gear to rotate, and the second rotating gear also rotates synchronously under the drive of the first rotating gear. However, the second rotating gear and the first rotating gear are designed to be externally meshed, and the two gears rotate in opposite directions. The two drums coaxial with the gears rotate in two different directions, so that the cable at the non-axial extension end of the motor is wound up and the cable at the axial extension end is released at the same time. The synchronous tightening and loosening process of the cable always keeps the motor in a stable flipping state; when the motor is flipped from the vertical state to the horizontal state, the ratchet steering handle 8 is rotated to the "horizontal" position, and the hand chain is operated to drive the hand chain wheel to rotate.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
