The passenger rolling ship is also called a transport ship for opening and closing, and is a transport ship for directly entering and leaving a cargo hold to load and unload a semi-trailer or a wheel type tray loaded with box cargos or other cargos by using a tractor. Goods carried by the ro-ro passenger ship enter and exit the cargo compartment through the power of the ro-ro passenger ship and can carry passengers at the same time, and the ro-ro passenger ship is mainly used for river ferry and medium and short-range sea transportation. In order to facilitate the roll-on/roll-off operation, a relatively large cabin door (the cabin door is used as a passage or a springboard for connecting a wharf and a cabin after being opened during the roll-on/roll-off operation, hereinafter referred to as roll-on/roll-off equipment) is arranged on the ship body, so that goods or operation vehicles can smoothly enter and exit.
Specifically, due to the tolerance and error of the hull structure, the manufacturing precision of the roll-on-roll-off equipment steel structure, the scribing precision of the installation position of the hinge seat frame and the like, the hinge seat frame cannot cut the allowance in advance. Therefore, the hinge seats on the ship body are installed on site, namely, the installation positions of the hinge seats on the ship body are determined according to the positions of the hinge seats on the roll-on equipment after the position of the roll-on equipment relative to the ship body is well positioned, and then the specific allowance of the hinge seats to be cut can be determined.
The installation method of the hinge seat in the prior art mainly comprises the following steps: 1. the hinge seat frame is positioned in advance according to the requirements of the drawing. 2. And the roll-on equipment is positioned according to the requirements of the drawing. 3. After the ship block structure is formed, the roll-on equipment is installed in place according to the technical requirements of drawings. And 4, marking the allowance of the hinge seat according to the installation position of the roll-on equipment. 5. And removing the hinge base, placing the hinge base on a stable deck, performing allowance cutting, welding a groove, and polishing. 6. The hinge block is repositioned. 7. The hinge seat is aligned with the hinge hole of the roll-on-roll-off equipment. 8. And finishing the installation of the hinge base.
Further, the above-mentioned mounting method for the hinge base in the prior art has the following disadvantages: 1. various labor investments are large: because the integral dead weight of the hinge seat frame is larger, the weight is 200 KG-500 KG generally, the carrying and the lifting can not be finished only by manpower, the carrying and the lifting can be finished by a hoist or a crane, the mounting height of part of the hinge seat frame reaches 4 meters, the existing method needs to carry out the lifting more than 3 times at least so as to facilitate the scribing, namely, the cutting allowance is determined; and 2 fitters and 1 crane are needed for each hoisting operation, the hoisting operation period is long, and the hoisting operation needs to be repeated for more than 3 times. The workload of the scaffold building worker is large: because the hinge mounting position is higher, need the scaffold frame of shelf worker set up the scaffold frame many times, the hinge seat frame takes one time of putting up, and roll-on equipment takes one place to install and need tear open the frame once, and roll-on equipment takes one place to finish, needs to put up once, admittedly need 3 times scaffold frame tear open and take at least. 2. The marking requirements for the bench worker are high: the requirement of large-scale roll-on equipment on shaft hole centering of the hinge seat is high, and the diameter of the shaft hole is generally 0.05mm-0.20 mm. Through the existing real object marking method, the requirement on the technical capability of workers is high, errors are easy to occur, and the reworking is caused, namely the construction difficulty is high. 3. The whole work flow needs more than 15 days of continuous construction of various types. In summary, the installation method of the hinge seat in the prior art has the disadvantages of relatively high construction difficulty, long construction period and high construction cost.

Specifically, in this embodiment, the installation position refers to a position on the hull 1 for fixing a hinge seat, where the hinge seat is mainly used to connect a roll-on device (a cabin door or a springboard), and a hinge member that is matched with the hinge seat is provided on a prefabricated roll-on device, and a shaft hole is provided on the hinge member, that is, after the hinge member is connected with the hinge seat by a pin, the roll-on device can rotate relative to the hull 1. The shaft hole of the hinged part is called a first reference position, that is, after the specific position of the roll-on device relative to the ship body 1 is determined, the position of the first reference position relative to the ship body 1 is naturally determined; of course, the roll-on device and the hull 1 are only temporarily fixed at this time, and after the installation of the hinged seat is completed, the roll-on device is connected with the hull 1 through the hinged seat.
S2, mounting the cutting allowance auxiliary tool 2 on the first reference position; because the articulated elements on the roll-on equipment are coaxial with the articulated seat on the hull 1, consequently, will cut surplus auxiliary fixtures 2 and install on the first reference position (shaft hole) of roll-on equipment, can confirm the concrete position relation of shaft hole (second reference position) relative to hull 1 of articulated seat.
S3, adjusting the boundary of the cutting allowance auxiliary tool 2 according to the position relation between the first reference position and the hinge seat mounting position; after the cutting allowance auxiliary tool 2 is installed and fixed on the first reference position, the position and/or spatial relationship of the second reference tool relative to the ship body 1 is determined by adjusting the adjusting component of the cutting allowance auxiliary tool 2. For example, in the present embodiment, three connection surfaces are formed on the hull 1 and the hinge seat, and at this time, one adjusting piece on the auxiliary tool for adjusting the cutting allowance 2 is abutted to one of the connection surfaces; this also defines the boundary or contour of the connection of the articulated seat to the body.
