[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 4 As shown, the present invention provides a motor shaft conveying sling for a generator set, comprising a sling body 1, with a support assembly 2 and an auxiliary assembly 3 provided on the outside of the sling body 1; the sling body 1 is an existing motor shaft conveying sling; the support assembly 2 and the auxiliary assembly 3 are consistent with the sling body 1 except for some additional materials;

[0027] The sling body 1 includes a connecting rod 11, a connecting block 12 and a mounting ring seat 14. The connecting block 12 is used to connect the sling, and the mounting ring seat 14 is used to sleeve one end of the motor shaft.

[0028] The support assembly 2 includes a mounting head 21, an upper slide bar 22, and a lower slide bar 23. The upper slide bar 22 and the lower slide bar 23 are used to limit the sliding of the auxiliary assembly 3;

[0029] The auxiliary component 3 includes an upper kit 31, a lower kit 32, a slider 34 and a roller 39. The upper kit 31 is fixedly connected to the lower kit 32. The upper kit 31, the lower kit 32 and the roller 39 are used to auxiliary support one end of the motor shaft. The slider 34 is used to adjust the height of the upper kit 31 and the lower kit 32.

[0030] In a further embodiment, the mounting head 21 is connected to the connecting rod 11 by bolts, the upper slide rod 22 is located above the lower slide rod 23, and a friction strip 24 is installed inside the lower slide rod 23, and the friction strip 24 is used to cooperate with the slider 34.

[0031] In this embodiment, the upper slide bar 22 is provided with a through slide groove, while the lower slide bar 23 is a recessed slide groove for cooperating with the adjustment of the adjustment bolt 36 .

[0032] In a further embodiment, one end of the upper slide bar 22 and the lower slide bar 23 are fixedly connected to one side of the mounting head 21 , and the other end of the upper slide bar 22 and the lower slide bar 23 are installed with a limit head 25 , which is used to limit the auxiliary component 3 .

[0033] In this embodiment, the limit head 25 is detachable, so as to facilitate the installation of the slider 34 and the friction strip 24 that slide between the upper slide bar 22 and the lower slide bar 23, thereby facilitating maintenance and assembly.

[0034] In a further embodiment, four support blocks 38 are fixedly connected to the inner side of the lower sleeve 32 , and rollers 39 are distributed between two adjacent support blocks 38 , and the rollers 39 are rotatably connected to the support blocks 38 .

[0035] In this embodiment, there are three rows of rollers 39, two in a row, and the outer periphery of the roller 39 is higher than the support block 38, so that it can contact the motor shaft first. After the roller 39 is deformed, the support block 38 will contact the outer periphery of the motor shaft, thereby preventing the passive sliding of the entire auxiliary component 3 during auxiliary support; the support block 38 is composed of an iron block with a rubber pad on the outside.

[0036] In a further embodiment, a vertical slide groove 33 is provided at the top of the inner side of the upper sleeve 31 , a slider 34 is slidably connected inside the slide groove 33 , and a top cover 37 is installed above the slider 34 .

[0037] In this embodiment, dovetail blocks are provided on both sides of the slider 34 to cooperate with the dovetail grooves provided on the inner side of the slide groove 33 to limit the range of its upward and downward sliding.

[0038] In a further embodiment, the top cover 37 is internally rotatably connected to an adjusting bolt 36 , which passes through the top of the threaded upper kit 31 , and a friction strip 2 35 is installed below the slider 34 , and the friction strip 2 35 is used to cooperate with the friction strip 1 24 .

[0039] In this embodiment, a hole is provided in the top cover 37 to allow part of the adjusting bolt 36 to pass through, thereby forming a movable connection, and the adjusting bolt 36 passes through the top of the upper sleeve 31 located at the slide groove 33 when the threaded connection is made. Therefore, when the adjusting bolt 36 rotates, the slider 34 will move up and down. When the slider 34 moves down, the upper sleeve 31 and the lower sleeve 32 will move up, and conversely, the upper sleeve 31 and the lower sleeve 32 will move down relative to each other, thereby controlling the height of the other end of the motor shaft, thereby controlling the tilt angle and facilitating the installation of the motor shaft; the friction strip 2 35 and the friction strip 1 24 are both friction parts with a certain elasticity and a rough surface, thereby preventing the auxiliary component 3 from sliding during auxiliary support by increasing friction.

[0040] In a further embodiment, the connecting block 12 is sleeved on one end of the connecting rod 11, and the other end of the connecting rod 11 is fixedly connected to the mounting ring seat 14. A rubber ring 15 is provided inside the mounting ring seat 14, and the connecting rod 11 is located on the inner side of the connecting block 12 and is fixedly connected to the auxiliary card blocks 13 that are evenly arranged and distributed.

[0041] In this embodiment, the rubber ring 15 and the roller 39 are both made of rubber and are used to protect the motor shaft during lifting. When the motor shaft is inserted into the rubber ring 15, the motor shaft can be lifted by the lever principle, which is the principle of the existing lifting device; the auxiliary block 13 is used to enhance the connection strength between the mounting ring seat 14 and the connecting rod 11.

[0042] The working principle of this utility model is as follows:

[0043] When the motor shaft in the motor group needs to be hoisted, the hoisting cable can be connected to the ring on the top of the connecting block 12, and then the mounting ring seat 14 is sleeved on one end of the motor shaft. Then, the sliding position of the connecting block 12 and the position of the auxiliary component 3 are adjusted to find a balanced position for hoisting;

[0044] When the mounting ring seat 14 is sleeved on one end of the motor shaft, the motor shaft will also pass through the inner side of the upper sleeve 31 and the lower sleeve 32. At this time, the outer surface of the motor shaft will contact the roller 39, so that the lower sleeve 32 and the upper sleeve 31 can support the electrode shaft through the support block 38. Then, the upper sleeve 31 and the lower sleeve 32 can be slid to make the slider 34 slide between the upper slide bar 22 and the lower slide bar 23, so that the entire auxiliary component 3 can be moved to the other end of the motor shaft, thereby allowing the auxiliary component 3 to assist in supporting the other end of the motor shaft as a whole, and the roller 39 can rotate during the movement. After the movement stops, the adjusting bolt 36 can be rotated to make the top cover 37 move down with the slider 34, thereby allowing the upper sleeve 31 and the lower sleeve 32 to move up, thereby increasing the pressure of the motor shaft on the roller 39, thereby preventing sliding. In addition, the downward movement of the slider 34 will also increase the friction between the friction bar 2 35 and the friction bar 1 24, further preventing the auxiliary component 3 from sliding during lifting.

[0045] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
