[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] See also Figures 1 to 4In this embodiment, a transport pulley block for annealing a flywheel housing is provided, comprising a movable seat 1, a winding drum 3 is installed above the movable seat 1, a steel cable 4 is wound around the winding drum 3, a movable pulley block 5 is provided below the movable seat 1, and one end of the steel cable 4 passes through the movable pulley block 5 and is fixedly connected to the lower end of the movable seat 1;

[0023] The movable pulley block 5 comprises a connecting frame 51 , a pulley 52 is rotatably connected inside the connecting frame 51 , a connecting column 53 is connected below the connecting frame 51 , and a plurality of rotatable claws 55 are installed inside the lower end of the connecting column 53 .

[0024] When in use, the steel cable 4 can be rolled up or down by retracting and releasing the winding drum 3 above the movable seat 1, and the steel cable 4 drives the movable pulley block 5 to move up and down. The movable pulley block 5 moves up and down to drive the annealed flywheel housing to move up and down, and the movable seat 1 drives the flywheel housing to move to the storage position.

[0025] When the flywheel housing is lifted, the connecting column 53 is inserted into the shaft hole of the flywheel housing, and then the claws 55 are unfolded. The distance between the claws 55 after unfolding is greater than the diameter of the shaft hole so that the claws cannot pass through the shaft hole. Therefore, the movable pulley block 5 drives the flywheel housing to rise through the claws 55 when rising.

[0026] In further embodiments, see Figure 3 The lower end of the connecting column 53 is provided with a slot for accommodating the rotation of the claw 55. One end of the claw 55 is rotatably connected to the lower end of the connecting column 53. One end of the claw 55 is located inside the connecting column 53 and has a tooth groove on the outside. A rack 56 is slidably connected to the inside of the connecting column 53. The rack 56 meshes with one end of the claw 55. A connecting rod 57 is fixedly connected to the upper end of the rack 56. A rotating block 54 is rotatably connected to the upper end of the connecting column 53. The connecting rod 57 is rotatably connected to the rotating block 54. The rotating block 54 rotates and moves up and down, thereby driving the connecting rod 57 to move up and down. The connecting rod 57 drives the rack 56 to move up and down. The rack drives one end of the claw 55 with the tooth groove to rotate. One end of the claw 55 rotates and rotates out from the inside of the connecting column 53. The unfolded connecting column 53 is larger than the shaft hole of the flywheel housing, so that the claw 55 cannot be separated from the flywheel housing. When there are multiple claws 55, there are also multiple tooth grooves on the outer side of the rack 56, and the tooth grooves correspond to and mesh with one end of the claw 55 with the tooth grooves one by one, so that the multiple claws 55 can be driven to rotate together. The multiple claws 55 can increase the weight of the flywheel housing supported by the pulley group, and it is also more stable during transportation.

[0027] In further embodiments, see Figure 3The lower end of the rotating block 54 is provided with a circular ring, and the connecting rod 57 is arranged horizontally, and the two ends of the connecting rod 57 pass through the connecting column 53 and are located between the connecting rod 57 and the rotating block 54. The rotating block 54 rotates to drive the circular ring to rise or fall, and the circular ring rises or falls to drive the connecting rod 57 to rise or fall, and the connecting rod 57 drives the rack 56 to move up and down.

[0028] In further embodiments, see Figure 4 The clamping claw 55 includes a rod body 551, one end of which is threadedly connected with a rotating head 553, and a protective plate 552 is inserted into the rod body 551. A plurality of elastic protrusions are provided on the upper end of the protective plate 552. The rotating head 553 can be separated from the rod body 551 by rotating it, so that the protective plate 552 can be slid out from one end of the rod body 551, so that the protective plate 552 can be replaced after being worn. The flywheel housing can be clamped by the plurality of protrusions on the protective plate 552, and the protrusions are elastic so as to reduce the friction on the shaft hole and reduce the damage to the shaft hole.

[0029] In further embodiments, see Figures 2-3 The lower end of the connecting column 53 is provided with a plurality of inclined grooves, and the claws 55 are located inside the inclined grooves after rotation. The inclined grooves allow the claws 55 to tilt downward after being unfolded, and a cone is formed by the plurality of claws 55. The conical claws can match the size of the shaft hole of the flywheel housing, so as to prevent the flywheel housing from shaking easily during the movement.

[0030] In further embodiments, see Figure 1 The driving device 2 is fixedly mounted on the movable seat 1, and the driving device 2 is connected to one end of the winding drum 3. The winding drum 3 can be rotated by the driving device 2, and the steel cable 4 can be rolled up or down by the rotation of the winding drum 3, thereby realizing the lifting and lowering action of the movable pulley block 5.

[0031] In further embodiments, see Figure 1 A plurality of rollers are arranged on the periphery of the moving seat 1. The plurality of rollers can reduce the friction between the moving seat 1 and the subsequent walking track, so that the moving seat 1 can be driven to move by an external driving force.
