However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] PCTC (Pure Car and Truck Carrier) is a ship specially designed for transporting cars and trucks. One of its features is that it is equipped with a lifting deck to facilitate the loading and unloading of vehicles. Traditionally, the lifting decks of these ships usually adopt thin plate structures with a thickness of 6mm, and the size of the single deck is relatively large. In the past, the common loading and unloading method was to hoist on the deck by welding lifting horses, and it was necessary to use external lifting equipment to connect the lifting rings to achieve the lifting of the deck.

[0026] However, the existing traditional method is prone to deformation of the deck during the lifting process, and the lifting rings welded to the deck need to be removed after the lifting is completed.

[0027] In order to reduce the damage to the parent material caused by welding hoists and subsequent cutting in the traditional hoisting method, the present application provides a special device for hoisting a PCTC lifting deck.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses a special device for lifting a PCTC lifting deck. Figure 1 , Figure 2A PCTC lifting deck hoisting device includes a horizontally arranged hoisting frame 1, a leveling component 4 is arranged at the bottom of the hoisting frame 1, a plurality of connection points 3 are arranged on the leveling component 4, and a connection component 2 is arranged at the position of the connection point 3. The height positions of the plurality of connection points 3 are leveled by the leveling component 4 so that the heights of the plurality of connection points 3 are equal. The deck surface is supported and fixed by the connection component 2 arranged on the connection point 3, so that the deck is hoisted by the hoisting frame 1 driving the connection component 2.

[0030] The leveling assembly 4 includes a hoisting code plate 41 at the bottom end of the hoisting frame 1, the hoisting code plate 41 is fixedly connected to the hoisting frame 1, and a leveling roller 42 is arranged between two opposite hoisting code plates 41, the leveling roller 42 is relatively connected to the bottom wall of the hoisting frame 1 through a connecting plate 22, the rolling surface of the leveling roller 42 is relatively rotatably connected to the hoisting frame 1, and the connecting line formed between the multiple leveling rollers 42 is arranged parallel to the hoisting frame 1.

[0031] A steel wire rope 43 is passed through the rolling surface of the multiple leveling rollers 42, and the side wall of the steel wire rope 43 abuts against the rolling surface of the leveling roller 42, and the steel wire rope 43 between two adjacent leveling rollers 42 is relatively connected to the connection point 3. The end of the steel wire rope 43 is fixedly connected to the lifting ring 21 at the bottom end of the hanging frame 1. The steel wire rope 43 and the connection point 3 are driven by the multiple leveling rollers 42 to move and adjust, so that the heights of the multiple connection points 3 are the same, and the connection line formed by the multiple connection points 3 is arranged parallel to the hanging frame 1.

[0032] Reference Figure 3 , Figure 4 The connection component 2 located at the connection point 3 includes a lifting ring 21, which is fixedly connected to the wire rope 43, and the bottom end of the lifting ring 21 is fixedly connected to a connecting plate 22, which is vertically arranged, and the top end of the connecting plate 22 is located on the side wall of the lifting ring 21 and is fixed by a pin shaft.

[0033] Two connecting plates 22 are arranged opposite to each other, and the two connecting plates 22 are arranged along the thickness direction of the hanging ring 21 . The two connecting plates 22 are respectively located on both sides of the hanging ring 21 , and the bottom ends of the two connecting plates 22 are fixed by horizontally arranged pins.

[0034] There is a gap between the two opposite connecting plates 22, and a receiving groove 221 is formed by the gap between the two connecting plates 22. A clamping plate 23 is arranged inside the connecting groove, and the bottom pin positions of the two opposite connecting plates 22 are hingedly connected to the clamping plate 23, so that the clamping plate 23 can rotate relatively inside the receiving groove 221.

[0035] The clamping plate 23 is divided into a first section 231 and a second section 232 by a latch, and the length of the first section 231 is smaller than the length of the second section 232. When the clamping plate 23 is rotated to a horizontal state, one end of the first section 231 away from the second section 232 and one end of the second section 232 away from the first section 231 extend from the inside of the receiving groove 221, and the second section 232 is located on the side close to the deck, and the deck is supported by the second section 232.

[0036] A cutout 2311 is formed on the side wall of the first sub-portion 231 away from the second sub-portion 232. The cutout 2311 is horizontally disposed and completely penetrates the side wall of the first sub-portion 231. In some embodiments, the length of the clamping plate 23 is 200 mm. The length of the second sub-portion 232 is 120 mm.

[0037] The connecting plate 22 is horizontally provided with an adjustment hole 24, which completely penetrates the side walls of the two connecting plates 22, and an adjustment plate 25 is inserted inside the connecting hole, and the adjustment plate 25 is relatively slidably connected to the connecting plate 22. A connecting rope 26 is fixedly connected to one end of the adjusting plate 25, and the end of the connecting rope 26 away from the adjusting plate 25 is fixedly connected to the lifting ring 21.

[0038] The distance between the adjustment hole 24 and the bottom pin is smaller than the distance between the end of the second section 232 and the bottom pin, so that when the fixing plate 23 is in a vertical state and located inside the receiving groove 221, the fixing plate 23 is opposite to the adjustment hole 24, and the adjustment plate 25 is extended into the adjustment hole 24, thereby pushing the fixing plate 23 to extend from the inside of the receiving groove 221.

[0039] When the fixing plate 23 is in a vertical state and located inside the accommodating groove 221, by extending the connecting plate 22 into the binding hole on the deck, the fixing plate 23 is pushed to a horizontal state through the adjusting plate 25, so that the top wall of the fixing plate 23 can abut against the side wall of the deck, and the side wall of the deck is supported and fixed by the fixing plate 23.
