[0025] As Figure 1-5 shown, the lifting equipment for ship maintenance includes a ship crane 1. Support moving wheels 2 are provided at the four corners of the bottom of the ship crane 1. A moving wheel positioning mechanism 3 is further included. The moving wheel positioning mechanism 3 is fixedly connected to the bottom of the ship crane 1 and is arranged on one side of the support moving wheel 2;

[0026] The protection mechanism 4 is fixedly connected to the front of the support moving wheel 2.

[0027] The moving wheel positioning mechanism 3 includes a transmission box 31. A moving frame 36, a motor 32 and a transmission mechanism cooperating with the motor 32 are arranged in the transmission box 31. The motor 32 is fixedly connected to the left side of the inner wall of the moving frame 36. The output end of the motor 32 is fixedly connected to a turntable 33. The right side of the turntable 33 is fixedly connected to a transmission column 34. The number of the transmission columns 34 is five. The surface of the transmission column 34 is slidably connected to a tooth plate 35. The top of the tooth plate 35 is fixedly connected to the top inner wall of the moving frame 36. The outer frame surface of the moving frame 36 is connected to one end of a transmission rod 37. The other end of the transmission rod 37 is connected to a friction positioning block 38.

[0028] Through the setting of the moving wheel positioning mechanism 3, the support moving wheel 2 can be limited, preventing the situation that when the support moving wheel 2 moves to a suitable position, additional limiting objects need to be set. The user starts the motor 32. The motor 32 drives the turntable 33 to rotate through the output end. The turntable 33 drives the transmission column 34 to rotate. The transmission column 34 meshes with the tooth plate 35, driving the tooth plate 35 to move forward. The tooth plate 35 drives the transmission rod 37 to move forward. The transmission rod 37 drives the friction positioning block 38 to move forward to the front side. The friction positioning block 38 positions the support moving wheel 2.

[0029] A further technical solution is that a protection mechanism 4 is further provided. The protection mechanism 4 includes a fixed frame 41. A movable protection plate 42 is slidably connected to the surface of the fixed frame 41. Support rods 43 are fixedly connected to both sides of the fixed frame 41. A screw rod 44 is threadedly connected inside the support rod 43. A rotating block 45 is fixedly connected to the right side of the screw rod 44. A fixed column 46 is fixedly connected to the left side of the rotating block 45.

[0030] Through the setting of the protection mechanism 4, the support moving wheels 2 can be protected, preventing external objects from directly hitting the surface of the moving wheels, and improving the service life of the moving wheels. By moving the protection plate 42 downward, when it moves to the right position, the rotating block 45 is driven by the anti-slip pattern 8. The rotating block 45 drives the screw rod 44 to rotate. The screw rod 44 enters the inside of the support rod 43, and the movable protection plate 42 is positioned through the fixed column 46 to perform the protection work on the support moving wheels 2.

[0031] A fixed plate 5 is fixedly connected to the bottom of the motor 32. The left side of the fixed plate 5 is fixedly connected to the left inner wall of the transmission box 31. A spring 6 is fixedly connected to the front of the movable frame 36. The front of the spring 6 is fixedly connected to the front inner wall of the transmission box 31. A support block 7 is sleeved on the surface of the transmission rod 37. The front of the support block 7 is fixedly connected to the front inner wall of the transmission box 31. An anti-slip pattern 8 is arranged on the surface of the rotating block 45. The anti-slip pattern 8 is used in cooperation with the rotating block 45. An opening 9 is formed on the surface of the movable protection plate 42. The width of the opening 9 is greater than the width of the support rod 43. The opening 9 is used in cooperation with the support rod 43.

[0032] Specifically, when the ship maintenance lifting equipment is in use: First, when the user moves the ship crane 1 to a suitable position through the support moving wheels 2, the user starts the motor 32. The motor 32 drives the turntable 33 to rotate through the output end. The turntable 33 drives the transmission column 34 to rotate. The transmission column 34 meshes with the toothed plate 35 to drive the toothed plate 35 to move forward. The toothed plate 35 drives the transmission rod 37 to move forward. The transmission rod 37 drives the friction positioning block 38 to move forward to position the support moving wheels 2. Then, the protection plate 42 is moved downward. When it moves to the right position, the rotating block 45 is driven by the anti-slip pattern 8. The rotating block 45 drives the screw rod 44 to rotate. The screw rod 44 enters the inside of the support rod 43, and the movable protection plate 42 is positioned through the fixed column 46 to perform the protection work on the support moving wheels 2.

[0033] Through the setting of the moving wheel positioning mechanism 3 of the ship maintenance lifting equipment, the moving wheels can be limited, preventing the situation that additional limiting objects need to be set when the moving wheels move to a suitable position. Through the setting of the protection mechanism 4, the moving wheels can be protected, preventing external objects from directly hitting the surface of the moving wheels, and improving the service life of the moving wheels.

[0034] The present utility model has been described exemplarily in conjunction with the accompanying drawings.
