Description
Technical Field
The invention belongs to the technical field of ship design and manufacturing, and particularly relates to a method for installing a hinge seat.
Background
Ships are an important water transport means, such as container carriers, natural gas carriers, bulk carriers, ro-ro vessels, etc. The rolling ship, also called as on-off ship, is a transport ship which is loaded and unloaded by directly entering and exiting a cargo hold by using a tractor to pull a semitrailer or a wheel type pallet carrying box cargo or other cargoes. The goods carried by the passenger rolling ship can enter and exit the warehouse through the power of the passenger rolling ship and can simultaneously carry passengers, and the passenger rolling ship is mostly used for inland river ferry and medium-short-range sea transportation. In order to facilitate the rolling operation, a relatively large cabin door is arranged on the ship body, (the cabin door is used as a passage or a gangway for connecting a wharf and a cabin when the rolling operation is performed, hereinafter referred to as rolling equipment for short) so that goods or operation vehicles can smoothly enter and exit, and further, the cabin door is relatively large, so that a hinge seat matched with the cabin door is relatively large, namely, the weight of the hinge seat often reaches two hundred to five hundred kilograms, and a certain difficulty and inconvenience are brought to the installation of the hinge seat.
Specifically, due to the accumulated tolerance and error of the precision deviation of the hull structure, the manufacturing precision of the steel structure of the roll-on-roll-off equipment, 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 hinging seats on the ship body are all installed on site, namely, the installation positions of the hinging seats on the ship body are determined according to the positions of the hinging seats on the roll-on equipment after the positions of the roll-on equipment relative to the ship body are positioned, and then the specific allowance required to be cut on the hinging seats can be determined.
The method for installing the hinge seat in the prior art mainly comprises the following steps: 1. and (5) the hinge seat frame is positioned according to the drawing requirements in advance. 2. The roll-on and roll-off equipment is positioned according to the drawing requirements. 3. After the ship block structure is formed, the roll-on and roll-off equipment is firstly installed in place according to the technical requirements of drawings. And 4, carrying out allowance scribing on the hinge seat according to the installation position of the roll-on/roll-off equipment. 5. And dismantling the hinge seat, placing the hinge seat on a stable deck for allowance cutting, welding a groove, and polishing and smoothing. 6. The hinge base is repositioned. 7. The hinge mount is centered with the roll-on and roll-off equipment hinge aperture. 8. And (5) finishing the installation of the hinge seat.
Further, the above-mentioned mounting method for the hinge base in the prior art has the following disadvantages: 1. the labor investment of various industries is large: because the whole dead weight of the hinge seat frame is large, the weight is 200 KG-500 KG in general, the lifting can not be finished only by manpower, and the lifting can not be finished by a hoist or a crane, and the installation height of part of the hinge seat frame is 4 meters, the current method needs to hoist more than 3 times at least so as to conveniently score lines, namely, determine the cutting allowance; and each lifting operation needs 2 bench workers and 1 crane, the lifting operation period is long, and the lifting operation needs to be repeated for more than 3 times. The work load of the frame erecting work is large: because the hinge mounting position is higher, the scaffold needs to be erected for a plurality of times by a scaffold worker, the hinge seat frame is erected once in place, the scaffold needs to be disassembled once before the roll-on and roll-off equipment is mounted in place, the roll-on and roll-off equipment is erected once in place, and the scaffold needs to be erected for a minimum of 3 times. 2. The scribing requirement for the fitter is high: the centering requirement of the large-scale roll-on roll-off equipment on the shaft hole of the hinge seat is relatively high and is generally 0.05mm-0.20mm. By the current real object scribing method, the technical capability requirement on workers is high, errors are easy to occur, and reworking, namely, construction difficulty is high. 3. The whole set of working flow needs continuous construction for more than 15 days. In summary, the method for installing the hinge seat in the prior art has the disadvantages of relatively high construction difficulty, long construction period and high construction cost.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to and integrated with the other element or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.
As shown in fig. 1-2, the present embodiment provides a method for installing a hinge seat, including a cutting allowance auxiliary tool 2 and a hinge seat to be processed, wherein the hinge seat is in a non-hoisting state, or the hinge seat is directly placed on the ground, and the method includes the following steps:
s1, determining the position of a first reference position and a hinge seat installation position. 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 for connecting roll-on equipment (a cabin door or a springboard), and the prefabricated roll-on equipment has a hinge piece matched with the hinge seat, and the hinge piece has a shaft hole, that is, after the hinge piece is connected with the hinge seat through a pin, the roll-on equipment can rotate relative to the hull 1. The shaft hole in the hinge is called the first datum position, that is to say, after the specific position of the roll-on device relative to the hull 1 is determined, the position of the first datum position relative to the hull 1 is naturally determined; of course, the roll-on device is only temporarily fixed to the hull 1 of the ship, and the roll-on device is connected to the hull 1 via the hinge base after the hinge base is installed.
S2, mounting a cutting allowance auxiliary tool 2 on a first reference position; because the hinge piece on the roll-on device is coaxially arranged with the hinge seat on the ship body 1, the cutting allowance auxiliary tool 2 is arranged on the first reference position (shaft hole) of the roll-on device, and the specific position relation of the shaft hole (second reference position) of the hinge seat relative to the ship body 1 can be determined.
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 fixture 2 is installed and fixed on the first reference position, the adjusting component of the cutting allowance auxiliary fixture 2 is adjusted to determine the position and/or the spatial relation of the second reference device relative to the ship body 1. For example, in this embodiment, three connection surfaces are formed on the hull 1 and the hinge base, and at this time, one adjusting piece on the auxiliary tool 2 for respectively adjusting the cutting allowance abuts against one of the connection surfaces; the boundary or contour of the connection of the hinge base to the body is thus also determined. Of course, the adjusting member is fixed after being adjusted or positioned so as to avoid the position of the adjusting member relative to the base 21 thereof from being changed.
And S4, removing the cutting allowance auxiliary tool 2 from the first reference position and installing the cutting allowance auxiliary tool on the second reference position of the hinging seat, and determining and cutting the allowance on the hinging seat to be processed according to the boundary of the cutting allowance auxiliary tool 2. Specifically, the fixed cutting allowance auxiliary tool 2 is arranged on the first basic position (shaft hole) of the roll-on equipment and is arranged on the second basic position (shaft hole) of the hinging seat to be processed; at this time, the area on the hinge seat outside the boundary or the outline of the auxiliary tool 2 for cutting allowance is the allowance to be cut, that is, the processing work of the hinge seat can be completed by cutting the allowance of the hinge seat along the boundary or the outline marked by the auxiliary tool 2 for cutting allowance.
S5, fixing the hinging seat after the allowance cutting to the mounting position. Specifically, hoisting the hinging seat after finishing allowance cutting to a corresponding position, enabling the boundary of the hinging seat to abut against the ship body 1, and finishing welding and fixing of the hinging seat; of course, in order to further improve the installation accuracy of the hinge base, before the hinge base is welded to the hull 1, a first reference position (shaft hole) located on the roll-on device and a second reference position (shaft hole) located on the hinge base may be connected by a pin, so that the hinge base and the roll-on device are centered, that is, the first reference position and the second reference position are centered, and then the hinge base and the hull 1 are welded and fixed.
Determining the position or the spatial relation between a first reference position (a shaft hole of a hinge seat prefabricated on rolling equipment) and an installation position (a ship body) through the cutting allowance auxiliary tool to adjust and determine the boundary or the outline of the cutting allowance auxiliary tool, and then integrally removing the cutting allowance auxiliary tool from the first reference position and installing the cutting allowance auxiliary tool on a second reference position of the hinge seat to be processed; at this time, the part of the hinge seat located outside the boundary is the margin required to be cut relative to the boundary of the cutting margin auxiliary tool. Compared with the prior art, the method for marking the positions of the hinging seat on the ship body to determine the allowance required to be cut on the hinging seat is needed to hoist the hinging seat on the corresponding positions of the ship body, so that the installation procedure of the hinging seat is effectively simplified, the cutting precision and the installation precision of the allowance on the hinging seat can be fully ensured, and the repairing probability is avoided or reduced. Meanwhile, the overall weight of the auxiliary tool for cutting allowance is negligible relative to the hinge seat, namely, the auxiliary tool is convenient for workers to easily install and adjust the boundaries of the auxiliary tool. Therefore, compared with the traditional hinge seat installation method, the precision deviation of the ship body structure, the steel structure manufacturing precision of the rolling equipment, the scribing precision of the installation position of the hinge seat frame and other accumulated tolerances and errors can be well avoided, and accurate allowance cutting and installation of the hinge seat can be affected. The labor investment of various industries is greatly reduced: the hoisting times of the hinge seat are effectively reduced, the novel method only needs to be carried out once, namely hoisting and installation of the hinge seat after allowance cutting are completed, and further the construction difficulty and construction period of the hinge seat are effectively reduced, and meanwhile, the construction cost is also reduced. Of course, the method of the hinge seat can be applied to the ship industry and other industries needing large-scale hinge seat installation.
Further, in the preferred embodiment, in step S4, a margin cutting line is further drawn on the hinge base along the boundary of the margin auxiliary tool 2, the margin auxiliary tool 2 is removed after the margin cutting line is drawn, and finally, the margin cutting is performed on the hinge base along the margin cutting line; or, the hinging seat is cut by the allowance along the boundary of the allowance auxiliary tool 2.
As shown in fig. 1-2, in a preferred embodiment, the auxiliary cutting allowance tool 2 includes a base 21, a positioning member 22 and a plurality of adjusting components, the positioning member 22 is connected with the base 21, the adjusting components are movably connected along the base 21, the adjusting components can be adjusted in a telescopic and/or rotational manner relative to the mounting position, and the positioning member 22 is used for connecting the first reference position or the second reference position. Wherein the positioning member 22 is matched with the first reference position (shaft hole) or the second reference position (shaft hole), i.e. after the positioning member 22 is inserted into the shaft hole, the outer wall of the positioning member is tightly attached to the inner wall of the shaft hole, thereby ensuring the use or adjustment precision of the auxiliary tool 2 for cutting allowance, i.e. the diameter of the positioning member 22 is the same as the diameter of the pin shaft for connecting the hinge seat and the hinge member.
Further, one end of the positioning member 22 is connected with the base 21, and the other end is a free end, i.e. the free end of the positioning member is used for being connected into the first reference position or the second reference position; meanwhile, in order to ensure the connection stability of the positioning member 22 and the first reference position or the second reference position, after the positioning member 22 is mounted in the reference position, the positioning member and the reference position can be fixed by a jackscrew or welding mode. Further, the positioning piece 22 is detachably fixed with the base 21, specifically, when the positioning piece 22 is detachable, the positioning piece 22 matched with the positioning piece 22 can be conveniently replaced aiming at shaft holes with different apertures, and therefore universality or applicability of the auxiliary tool 2 for cutting allowance is improved.
As shown in fig. 1-2, in a preferred embodiment, the adjusting assembly comprises at least a first rod 23 and a second rod 24, wherein a first end of the first rod 23 is rotatably connected to the base 21, a second end of the first rod 23 is rotatably connected to a first end of the second rod 24, and a second end of the second rod 24 is a free end. In this embodiment, the connection between the first rod 23 and the second rod 24 is achieved through the mutual cooperation of the bolt and the nut, or the connection between the first rod 23 and the base 21 is completed, for example, when the first rod 23 and the second rod 24 need to be fixed, only the nut or the bolt rod needs to be turned, and then the first rod 23 and the second rod 24 are clamped, that is, the fixation after the adjustment of the auxiliary tool 2 for cutting allowance is completed. Specifically, when the positioning member 22 is mounted in the second reference position of the hinge base, the position of the base relative to the hinge base can be determined, and at this time, the contour edge between the hinge base and the mounting position is drawn by extending or shortening each adjusting component, that is, the free end of the second rod 24 is abutted against the mounting position, or the movable plate 25 is abutted against the mounting position.
Further, in the preferred embodiment, the device further comprises a plurality of movable plates 25, each movable plate 25 is connected to each adjusting component, and the movable plates 25 are connected to the free ends of the second rod 24, and the movable plates 25 are rotatable relative to the second rod 24. Further, in another embodiment, each movable plate 25 is connected to two sets of adjusting components, one end of the movable plate 25 is rotatably connected to the free end of one second rod 24, and the other end of the movable plate 25 is rotatably connected to the free end of the other second rod 24. Specifically, when the connection surface (installation position) on the hull is relatively flat, the movable plate 25 can be used at this time, that is, the use of the movable plate is convenient for the staff to scribe the hinge seat along the edge thereof, or the use of the movable plate 25 can be more convenient for more accurately sketching the boundary of the allowance to be cut on the hinge seat, that is, the use precision of the auxiliary tool 2 for cutting allowance is improved.

The labor investment of various industries is greatly reduced: the hoisting times of the hinge seat are effectively reduced, the novel method only needs to be carried out once, namely hoisting and installation of the hinge seat after allowance cutting are completed, and further the construction difficulty and construction period of the hinge seat are effectively reduced, and meanwhile, the construction cost is also reduced.
