[0002] During ship construction, some equipment needs to be installed after the cabin is built. When installing the equipment in the cabin, it is necessary to first align the equipment with the base fixed to the bottom of the cabin, and mark the location of the bolt holes on the base. Then, move the equipment and drill bolt holes at the marked locations. After the bolt holes are drilled, move the equipment to the position opposite the bolt holes and connect the equipment to the base with bolts. When disassembling the equipment, it is necessary to remove each bolt and then move the equipment. Due to the small space in the cabin, when equipment needs to be moved during the installation or disassembly process, large lifting devices cannot be used. Currently, most equipment is moved by welding a lifting bracket on the cabin roof, connecting a hoist to the lifting bracket, and using the hoist to lift the equipment. However, the hoist can only move the equipment up and down. Drilling holes in the base under the equipment after lifting the equipment poses a safety hazard. Moreover, welding a lifting bracket on the cabin roof will damage the anti-corrosion layer of the cabin roof, reducing the anti-corrosion performance of the cabin roof. Summary of the Invention

[0029] like Figures 1 to 6 As shown, a preferred embodiment of an auxiliary device for loading and unloading equipment in a cabin of the present invention is used to move equipment to be installed in a cabin. The auxiliary device for loading and unloading equipment in a cabin comprises a guide rail 1 and a telescopic drive mechanism 2. The guide rail 1 is arranged parallel to the length direction of the bulb flat steel at the bottom of the cabin roof, and a holding mechanism 3 for holding the bulb flat steel is fixed to the upper part of the guide rail 1. The guide rail 1 is clamped on the bulb flat steel, and there is no need to weld a hanging code on the cabin roof, thereby avoiding the influence of the welding hanging code on the corrosion resistance of the cabin roof. The upper end sliding guide of the telescopic drive mechanism 2 is connected to the lower part of the guide rail 1, and the lower end of the telescopic drive mechanism 2 is provided with a hoist 4 for connecting the equipment to be installed. After the telescopic drive mechanism 2 is used to lift the equipment to be installed, the telescopic drive mechanism 2 is moved horizontally along the guide rail 1, so that the equipment to be installed can be moved to one side of the base, eliminating the safety hazards caused by working under the equipment to be installed.

[0030] Among them, such as Figure 2 、 Figure 3As shown, the clamping mechanism 3 includes a first clamping block 31, a second clamping block 32, and a connecting member. The first clamping block 31 is fixed to the upper end of the guide rail 1. The second clamping block 32 and the first clamping block 31 are arranged relative to each other in a direction perpendicular to the length of the guide rail 1. The connecting member is used to drive the second clamping block 32 toward or away from the first clamping block 31 to clamp or release the bulb flat steel. Specifically, when the second clamping block 32 approaches the first clamping block 31, the clamping mechanism can be clamped to the lower part of the bulb flat steel, thereby connecting the guide rail 1 to the bulb flat steel. When the second clamping block 32 moves away from the first clamping block 31, the clamping mechanism can be removed from the lower part of the bulb flat steel, facilitating the use of the auxiliary device for loading and unloading equipment in the cabin. The clamping mechanism 3 can be multiple or only one. When multiple clamping mechanisms 3 are provided, each clamping mechanism 3 is spaced apart along the length of the guide rail 1. When only one clamping mechanism 3 is provided, the first clamping block and the second clamping block are both strip plates with a length greater than or equal to the length of the guide rail.

[0032] In this embodiment, the connector includes a stud or bolt arranged perpendicular to the length of the guide rail 1 and passing through the lower portion of the first and second clamping blocks 31, 32. Specifically, the stud or bolt is screwed with a nut located on one side of the first and second clamping blocks 31, 32. The spacing between the first and second clamping blocks 31, 32 can be adjusted by tightening the nut.

Specifically, the sliding member 5 is a frame-type, and the hanging platforms on both sides of the inverted T-slot 51 are equipped with rollers to reduce the friction between the inverted T-slot 51 and the I-beam during sliding.

[0034] Furthermore, to prevent the slider 5 from sliding horizontally after being moved, a plurality of stop pin holes 11 are provided in the middle of the web of the I-beam. The stop pin holes 11 are spaced apart along the length of the I-beam, and the slider 5 is located between two adjacent stop pin holes 11. Stop pins 12 are provided in two adjacent stop pin holes 11 on both sides of the slider 5. Specifically, the stop pins 12 can be stop bolts that pass through the stop pin holes 11 and are then screwed with nuts.

Specifically, the first beam 41 and the second beam 43 are arranged vertically. The first beam 41 and the second beam 43 can maintain the relative positions of the first sling 42 and the second sling 44, prevent the first sling 42 and the second sling 44 from slipping on the equipment to be installed, thereby ensuring the stable connection of the first sling 42 and the second sling 44 to the equipment to be installed.

[0037] Furthermore, the first end of the first sling 42 and the second end of the first sling 42 are both fixedly connected with a first nut 45, and the first end of the first beam plate 41 and the second end of the first beam plate 41 are both passed through the upper and lower parts of the first bolt 46 that can move along the length direction of the first beam plate 41, and each first nut 45 is respectively screwed with each first bolt 46; the first end of the second sling 44 and the second end of the second sling 44 are both fixedly connected with a second nut 47, and the first end of the second beam plate 43 and the second end of the second beam plate 43 are both passed through the upper and lower parts of the second bolt 48 that can move along the length direction of the second beam plate 43, and each second nut 47 is respectively screwed with each second bolt 48.

Both ends of the second beam plate 44 are provided with second strip holes arranged along the length direction of the second beam plate, and the second bolts 48 are installed in the second strip holes. By moving the first bolt 46 or the second bolt 48, the sagging degree of the first sling 42 and the second sling 44 can be adjusted, and the center point of the first sling 42 and the center point of the second sling 44 can be arranged relative to the intersection of the first suspension beam 41 and the second suspension beam 43, thereby ensuring that the sling 4 can be lifted without a bottom lifting point.

[0038] Specifically, the first strip hole and the second strip hole are both through grooves with a length of 400 mm and a width of 30 mm. Reinforcing ribs with a length of 500 mm, a height of 40 mm and a thickness of 10 mm are provided on both sides of each through groove. The first sling 42 and the second sling 44 are both polymer fiber ropes with a width of 50 mm. The middle part of the first beam plate 41 and the middle part of the second beam plate 43 are connected by M45 bolts, and the upper part of the first beam plate 41 and the second beam plate 43 is fixed with a second lifting ring.

[0044] Specifically, when it is necessary to drill a hole on the base, first use the telescopic drive mechanism 2 to lift the device to be installed, and slide the telescopic drive mechanism to one side so that the device to be installed and the base are staggered up and down, and then drill the hole. After the drilling is completed, renovate the sliding telescopic drive mechanism so that the device to be installed and the base are opposite to each other up and down, and then extend the telescopic drive mechanism. After the construction is completed, remove the clamping mechanism 3 from the bulb flat steel.
