[0031] Working principle: As Figure 1-7As shown, when using a crane that is convenient for maintenance, a simple understanding of this device is as follows. First, when the crane needs to be maintained, rotate the cabinet lock 18 with a key to drive the rotating rod 16 to rotate. The rotating rod 16 drives the second bevel gear 15 to rotate, and the second bevel gear 15 drives the first bevel gear 14 to rotate. When the first bevel gear 14 rotates, the gear 12 rotates to drive the semi-tooth ring 11 to rotate, align the notch of the semi-tooth ring 11 with the connecting groove 9, rotate the cover door 6 outwards, and the connecting rod 8 at the rear of the cover door 6 disengages from the connecting groove 9, thereby opening the cover door 6 to maintain the inside of the crane. After the maintenance is completed, close the cover door 6 and rotate the cabinet lock 18 in the reverse direction. The semi-tooth ring 11 rotates to fix the connecting rod 8 in the connecting groove 9 and lock the cover door 6. When the hydraulic rod 5 is damaged and needs to be maintained, push the linkage rod 30 inwards. The fixing ring 33 on the linkage rod 30 squeezes the spring 32 towards the support ring 31 to move the guiding groove 29 away from the end of the capsule block 28. Then, pull the fixed cylinder 23 outwards from the ear 19. The capsule block 28 squeezes the fixing groove 22 to slide inside and outside the through hole 25, remove the hydraulic rod 5 and replace it with a new hydraulic rod 5. Insert the end of the fixed cylinder 23 through the ear 19 and the connecting plate 20 into the fixing groove 22 in the fixing block 21, and release the linkage rod 30. The spring 32 undergoes elastic deformation to reset the linkage rod 30. The guiding groove 29 squeezes the capsule block 28 to slide the capsule block 28 outwards in the through hole 25 and engage it in the fixing groove 22. The guiding groove 29 re-engages with the end of the capsule block 28 to fix the capsule block 28, thereby fixing the fixed cylinder 23 in the fixing block 21 to complete the replacement of the hydraulic rod 5. Start the hydraulic rod 5 through the operating platform 4 to lift and extend the cantilever 3, lower the hook, cooperate with other employees to fix the hook on the goods, lift the hook to lift the goods, and control the support body 2 to rotate along the support 1 to move the goods above the hull, lower the hook to place the goods on the ship, and cooperate with other employees to remove the hook. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
