The slots on the U-shaped channel plates 108 of the two support assemblies 1 are arranged opposite to each other. The two ends of the load-bearing beam 202 are respectively placed on the square frames of the two support assemblies 1 and are respectively held by the U-shaped channel plates 108 of the two support assemblies 1.

[0022] In one embodiment, the width of the two U-shaped groove plates 108 is matched with the width of both ends of the load-bearing beam 202, and the distance between the bottom of the grooves of the two U-shaped groove plates 108 is matched with the length of the load-bearing beam 202.

[0023] In one embodiment, both sides of the upper end of the U-shaped groove plate 108 are provided with outwardly inclined guide plates 109.

[0024] Understandably, this configuration facilitates the quick and accurate installation of the load-bearing beam 202 onto the support assembly 1, thereby reducing the workload during use and increasing convenience.

[0025] In one embodiment, the square frame includes two horizontal beams 106 and two vertical beams 105. The two ends of one horizontal beam 106 are welded to one end of each of the two vertical beams 105, and the two ends of the other horizontal beam 106 are welded to the other ends of each of the two vertical beams 105. A U-shaped channel plate 108 is fixedly connected to one horizontal beam 106, and two baffles 110 for locking the two sides of the load-bearing beam 202 are vertically fixedly connected to the other horizontal beam 106.

[0026] In one embodiment, reinforcing ribs 107 are provided between the two sides of the U-shaped channel plate 108 and a crossbeam 106, and between the side of the two baffles 110 that is far apart from each other and another crossbeam 106.

[0027] Understandably, this arrangement enhances the structural stability of the U-shaped channel plate 108 and the baffle plate 110 on the square frame, which facilitates the stable installation of the load-bearing beam 202 on the square frame.

[0028] In one embodiment, the support frame includes two vertical columns 102 and a connecting beam 103 horizontally fixed between the two vertical columns 102. The lower ends of the vertical columns 102 are fixedly connected to the deck above the cabin 3, and the upper ends of the four vertical columns 102 of the support assembly 1 are respectively fixedly connected to the four lower corners of the square frame.

[0029] In one embodiment, the upper and lower ends of the vertical column 102 are both welded with sealing plates 101; wherein, the lower sealing plate 101 is placed on the deck above the cabin 3 as a support, and the upper sealing plate 101 is welded to the square frame.

[0030] In one embodiment, a diagonal brace 104 is welded between the square frame and the support frame; this arrangement helps to improve the overall stability of the support assembly 1 and prevent the support assembly 1 from tipping over.

[0031] In one embodiment, the load-bearing beam 202 includes two channel steels with opposite openings welded together, and a first clamping plate 203 and two second clamping plates 201 are welded between the two channel steels; wherein, the lower part of the first clamping plate 203 extends out of the load-bearing beam 202 and is inserted between the two square frames, and the lower part of the second clamping plate 201 extends out of the load-bearing beam 202 and is inserted into the square frame; a plurality of mounting holes 204 are provided at the lower parts of the first clamping plate 203 and the two second clamping plates 201.

[0032] Understandably, this arrangement ensures that the load-bearing beam 202 is accurately and smoothly inserted between the U-shaped channel plate 108 and the two baffles 110, thereby increasing the convenience and versatility of the implementation process.

[0033] The process of using this utility model when disassembling the opening and closing hydraulic cylinder 7 is as follows: Confirm that the hydraulic cylinder 7 is in the extended position to ensure that the cabin door is closed. Insert the inspection pin into the pin hole of boom 8, remove the pin between boom 8 and opening / closing cylinder 7, and then retract the opening / closing cylinder 7. Install a hydraulic cylinder replacement device; Two chain hoists are hung on the lower part of the lifting beam 4, and the hooks at the lower end of the two chain hoists are reliably connected to the opening and closing cylinder 7 by wire rope or buckle. Hang another chain hoist in the mounting hole 204 at the lower part of the load-bearing beam 202, and reliably connect the hook at the lower end of the chain hoist to the opening and closing cylinder 7 by means of a wire rope or a buckle; The tilting posture of the opening and closing cylinder 7 is adjusted by using the chain hoist mounted on the lifting beam 4; the opening and closing cylinder 7 is pulled by the chain hoist mounted on the load-bearing beam 202 so that the opening and closing cylinder 7 moves towards the inspection hole 301. Adjust the chain hoists mounted on the lifting beam 4 and the load-bearing beam 202 to move the opening and closing cylinder 7 out of the inspection hole 301. This step involves changing the mounting position of the upper end of the chain hoist, for example, adjusting the upper end of the chain hoist from being mounted on the lifting beam 4 to being mounted on the load-bearing beam 202. In addition, when adjusting the mounting position of one chain hoist, it is necessary to ensure that the other two chain hoists are stably mounted. Adjust the chain hoist on the load-bearing beam 202 to make the opening and closing cylinder 7 horizontal, and then place the opening and closing cylinder 7 on the deck. After disassembling the cylinder replacement device, the cylinder 7 was lifted off the top of the ship lift using the bridge crane for further inspection and maintenance.

[0034] It should be noted that the connection between the opening / closing cylinder 7 and the cylinder support 6 needs to be disconnected before hoisting.

[0035] It should be noted that the process of using this utility model when installing the opening and closing cylinder 7 is the reverse of the process of using it when disassembling the opening and closing cylinder 7.

[0036] In summary, in this utility model, one hoist 5 can be installed on any mounting hole 204, and two hoists 5 can also be installed on the lifting beam 4 inside the ship compartment 3. After the lower ends of these three hoists 5 are connected to the opening and closing cylinder 7, the opening and closing cylinder 7 can be lifted and the tilt state of the opening and closing cylinder 7 can be adjusted so that the opening and closing cylinder 7 can be lifted out from the inspection hole 301, thereby facilitating replacement. In addition, this utility model has a simple structure, is easy to disassemble and assemble, and has strong versatility. It can also ensure that the opening and closing cylinder 7 can be easily disassembled or reinstalled from the main longitudinal beam in a narrow space.
