[0022] Please refer to the attached instructions Figures 1-6The present invention provides a lifting device for gearbox maintenance, comprising a support 1, a vertical support 2 is installed at the rear end of the support 1, and a maintenance platform 3 is arranged in front of the vertical support 2. A vertical installation through hole 21 is arranged inside the vertical support 2, in which a lifting drive mechanism 4 that can drive the maintenance platform 3 to rise and fall is installed. A suspension 5 is installed in front of the top of the vertical support 2, and a suspension mechanism 7 for lifting the gearbox to be repaired is installed below the suspension 5. A transfer mechanism 6 that drives the suspension mechanism 7 to transfer the gearbox to be repaired to the maintenance platform 3 is installed inside the suspension 5.

[0023] The specific structure of the maintenance platform 3 includes a horizontally distributed lifting platform 31, which provides a stable platform for placing and operating the gearbox. The mounting plate 32 installed on the back edge of the lifting platform 32 serves to connect and support other components. The four-claw chuck 34 distributed on the front side of the mounting plate 32 for clamping the main shaft inside the gearbox can firmly clamp the main shaft of the gearbox to ensure the stability of the gearbox during operation. The vertical mounting groove 321 distributed inside the mounting plate 32 provides installation space for the positioning mechanism 33. There is also a positioning mechanism 33 installed inside the vertical mounting groove 321 for driving the four-claw chuck 34 to move up and down to drive the clamped gearbox main shaft out of the gearbox. Through this mechanism, the gearbox main shaft can be driven to lift out of the gearbox, which is convenient for subsequent maintenance operations.

[0024] The specific structure of the positioning mechanism 33 is a first reduction motor 331 installed at the bottom end of the vertical mounting groove 321, which provides a power source. The first drive screw 332 connected to the output end of the first reduction motor 331 rotates under the drive of the motor. The first screw sleeve 333 threadedly sleeved on the first drive screw 332, when the screw rotates, the sleeve will move up and down along the screw, and its front side tube wall will be connected with the back center of the four-claw chuck 34, thereby driving the four-claw chuck 34 to move up and down, realizing the operation of lifting the main shaft of the gear box away from the gear box.

[0025] The specific structure of the lifting drive mechanism 4 includes a second reduction motor 41 installed at the top position in the vertical installation through hole 21, which serves as a lifting power device. The second driving screw 42 connected to the output end of the second reduction motor 41 rotates under the action of the motor. The second screw sleeve 43 is threadedly sleeved on the second driving screw 42. As the screw rotates, the sleeve moves up and down along the screw, and its front side pipe wall is connected to the back center of the mounting plate 32 in the maintenance platform 3, thereby realizing the lifting action of the maintenance platform 3, and the gear box can be lifted or lowered to a suitable maintenance height.

[0026] The specific structure of the transfer mechanism 6 includes a third drive screw 62 installed in the suspension 5, which plays the role of transmitting power and guiding the direction of movement. The third reduction motor 61 installed at the front end of the suspension 5 has its output end connected to the front end of the third drive screw 62 to provide power for the rotation of the screw. The third screw sleeve 63 is threadedly sleeved on the third drive screw 62. When the screw rotates, the sleeve moves horizontally along the screw, and its bottom pipe wall is connected to the top of the suspension mechanism 7, thereby realizing the horizontal movement of the suspension mechanism 7, so as to accurately transfer the gear box to the maintenance platform 3.

[0027] The specific structure of the suspension mechanism 7 includes a mounting frame 71 connected to the transfer end of the transfer mechanism 6, which plays a role of connection and support. The winding roller 72 installed below the mounting frame 71 is used to reel in and release the suspension cable 74. The suspension cable 74 wound on the winding roller 72 controls the height of the suspension by winding and releasing. The fourth reduction motor 73 installed on the side of the mounting frame 71 for driving the winding roller 72 to rotate provides power for the reeling and releasing of the suspension cable. The hanger 75 installed at the lower end of the suspension cable 74 is used to carry the gear box. The suspension ropes 76 installed at the four corner ends of the hanger 75 enhance the stability of the suspension. The hook 77 installed at the bottom end of each suspension rope 76 is convenient for connecting with the gear box for lifting.

[0028] A reinforcing angle steel 8 is provided at the connecting corner of the suspension 5 and the vertical support 2, which enhances the structural strength of the connecting portion of the suspension 5 and the vertical support 2 and ensures the stability and safety of the entire device. Working principle: The fourth reduction motor 73 of the suspension mechanism 7 is started to drive the winding roller 72 to rotate, release the suspension cable 74, and make the hanger 75 descend.

[0029] Connect and fix the hook 77 to the gear box to be repaired.

[0030] The fourth reduction motor 73 is started again, the hoisting cable 74 is reeled in, and the gearbox to be repaired is hoisted.

[0031] The third reduction motor 61 of the transfer mechanism 6 is started, and its output end drives the third driving screw 62 to rotate.

[0032] The third screw sleeve 63 threadedly sleeved on the third driving screw 62 moves horizontally along the screw, and because its bottom tube wall is connected with the top of the mounting frame 71 of the suspension mechanism 7, the suspension mechanism 7 is driven to move horizontally, and the gearbox to be repaired is accurately transferred to the top of the maintenance platform 3.

[0033] The fourth reduction motor 73 of the suspension mechanism 7 is started, the suspension cable 74 is released, and the gearbox to be repaired is placed on the lifting platform 31 of the repair platform 3.

[0034] The second reduction motor 41 of the lifting drive mechanism 4 is started to drive the second driving screw 42 to rotate.

[0035] The second lead screw sleeve 43 threadedly sleeved on the second drive lead screw 42 moves up and down along the lead screw. Since the front side wall thereof is docked with the center of the back of the mounting plate 32 in the maintenance table 3, the lifting action of the maintenance table 3 is realized, and the gearbox is lifted or lowered to a suitable maintenance height.

[0036] The inner main shaft of the gearbox is clamped by the four-jaw chuck 34 to ensure the stability of the gearbox during operation.

[0037] Start the first reduction motor 331 of the position adjustment mechanism 33 to drive the first drive lead screw 332 to rotate.

[0038] The first lead screw sleeve 333 threadedly sleeved on the first drive lead screw 332 moves up and down along the lead screw. Since the front side wall thereof is docked with the center of the back side of the four-jaw chuck 34, the four-jaw chuck 34 is driven to lift and lower, so as to drive the main shaft of the clamped gearbox out of the inside of the gearbox, facilitating subsequent maintenance operations.
