[0024] The following will be described in combination with the accompanying drawings Figures 1-3 The present application will be further described in detail.

[0025] The present application discloses a repair support frame for a ship side thruster.

[0026] Referring to Figure 1 A repair support frame for a ship side thruster, comprising a rack 1, a crane 2 is slidably installed on the rack 1, a lifting hook 21 is arranged on the crane 2, and the crane 2 is used to drive the lifting hook 21 to rise and fall on the rack 1. A support frame 3 is arranged on the rack 1, the support frame 3 is used to support the ship side thruster, and the support frame 3 is provided with a sliding assembly 4 and a fixing assembly 5, the support frame 3 slides on the rack 1 through the sliding assembly 4, and the fixing assembly 5 is used to fix the ship side thruster.

[0027] Referring to Figure 1, the crane 2 is slidably installed on the rack 1, the chain 22 is connected between the crane 2 and the hook 21, in use, the crane 2 controls the hook 21 to rise and fall through the chain 22, when it is needed to move the ship side thruster, the hook 21 is lowered, when the hook 21 is arranged on the ship side thruster, the crane 2 hoists the ship side thruster through the hook 21, then the crane 2 slides on the rack 1, and the ship side thruster is moved. Further, the displacement sensor 11 is arranged on the rack 1, two displacement sensors 11 are oppositely arranged on the rack 1, the crane 2 slides between the two displacement sensors 11 on the rack 1, so that the stability of the crane 2 sliding on the rack 1 is improved.

[0028] After the ship side thruster is hoisted, the support frame 3 is used to support the ship side thruster, in order to improve the stability of the support frame 3 supporting the ship side thruster, the support frame 3 is oppositely arranged on the rack 1, in use, the two support frames 3 are moved to the side close to or away from each other, so that the stability of the support frame 3 supporting the ship side thruster is improved.

[0029] Referring to Figures 1-2 , in order to improve the convenience of the support frame 3 sliding on the rack 1, the sliding assembly 4 assembly includes the sliding cylinder 41 and the roller 42, the sliding cylinder 41 is arranged at intervals on the support frame 3, the four sliding cylinders 41 are vertically installed on the support frame 3, and the four sliding cylinders 41 are all close to the rack 1. The roller 42 corresponds to the sliding cylinder 41, and the roller 42 is installed on the end of the piston rod of the sliding cylinder 41 close to the rack 1. In the initial state, the support frame 3 is directly placed on the rack 1, when it is needed to move the support frame 3, the piston rod of the sliding cylinder 41 is extended, the four rollers 42 lift the support frame 3, when the support frame 3 is moved to the specified position, the piston rod of the sliding cylinder 41 is retracted, so that the support frame 3 can be placed on the rack 1, thereby ensuring the supporting effect of the support frame 3 on the ship side thruster, and the support frame 3 can also be moved on the rack 1.

[0030] Further, in order to improve the stability of the support frame 3 sliding on the rack 1, the sliding groove 12 is arranged on the rack 1, the sliding grooves 12 are parallelly and intervally arranged on the rack 1, in use, the sliding cylinder 41 drives the roller 42 to be embedded into the sliding groove 12, so that the roller 42 can slide along the sliding groove 12, and the stability of the support frame 3 sliding is improved.

[0031] Referring to Figures 2-3The guide slot 13 is parallel and spaced apart from the sliding slot 12. The support frame 3 is provided with a connecting rod 31, one end of the connecting rod 31 is connected with the rack 1, and the other end penetrates into the guide slot 13. Further, the end of the connecting rod 31 penetrating into the guide slot 13 is provided with a limiting plate 32, the limiting plate 32 is installed on the connecting rod 31, and the limiting plate 32 is spaced apart from the guide slot 13. During use, the limiting plate 32 lifts the rack 1, at this time, the limiting plate 32 limits the rack 1, preventing the rack 1 from being lifted too much, and when the sliding cylinder 41 controls the rack 1 to descend, the support frame 3 is placed on the rack 1 again.

[0032] In order to improve the stability of the support frame 3 on the rack 1, the sliding slot 12 of the rack 1 is provided with a positioning hole 14, the positioning hole 14 is uniformly and spaced apart from the sliding slot 12, and the support frame 3 is provided with a positioning cylinder 33, the positioning cylinder 33 is installed on the rack 1, and the piston rod of the positioning cylinder 33 faces the side close to the rack 1. When the support frame 3 moves to the specified position, the piston rod of the positioning cylinder 33 extends to the side close to the rack 1, and the piston rod of the positioning cylinder 33 is inserted and matched with the positioning hole 14 on the rack 1, thereby preventing the support frame 3 from relatively sliding during the maintenance of the ship side thruster.

[0033] Referring to Figure 2 Further, the fixing assembly 5 includes a fixing cylinder 51 corresponding to the support frame 3, and the fixing cylinder 51 is installed on the corresponding support frame 3, and the two fixing cylinders 51 face each other. In addition, one end of the piston rod of the fixing cylinder 51 is provided with a fixing plate 52, the fixing plate 52 is arc-shaped as a whole, and the arc-shaped openings of the two fixing plates 52 face each other. When the ship side thruster moves between the two fixing plates 52, the fixing cylinder 51 drives the fixing plate 52 to move to the side close to each other, so that the fixing plate 52 can abut against the ship side thruster, preventing the ship side thruster from shaking during maintenance.

[0034] Referring to Figure 3 In addition, the top of each of the two support frames 3 is provided with a support plate 15, the support plates 15 are parallel to each other, and the support spring 151 is arranged between the support plate 15 and the support frame 3. When the ship side thruster is placed on the support plate 15, the support spring 151 is compressed, and the support spring 151 buffers the impact force when the ship side thruster is placed down, thereby reducing the pressure of the support frame 3.

[0035] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
