[0049] The application also provides a modular assembled backhoe dredger assembling method, in Figure 8 which, the method comprises the following steps:

[0050] S1, the third ship body 3 is positioned and leveled.

[0051] Specifically, two cranes are used to lift the third ship body 3 to the predetermined position, and the third ship body is balanced left and right, and there is no risk of overturning under no wind and wave conditions, and only needs to be fixed in position by mooring, and the hook is released after positioning.

[0052] Wherein, the lifting needs to be slow, smooth, prevent the two crane boom cross situation, the third hull 3 on the prohibition of any movable object, to prevent falling caused by the accident or loss of goods delay the construction period, while strictly control the levelness of the third hull 3.

[0055] The gap and the height difference of the joint surface of the third hull 3 and the fourth hull 4 are checked, the water excavator is used to assist in leveling, and it is ensured that the gap is uniform and flush. And the vertical pin 7 is inserted into the part of the clamping groove 6 of the third hull 3 and the fourth hull 4, so that the third hull 3 and the fourth hull 4 are preliminarily locked.

[0056] Wherein, when the third hull 3 and the fourth hull 4 are connected, it is strictly prohibited to directly put hands into the joint of the third hull 3 and the fourth hull 4, and tools must be used for adjustment, and it is strictly prohibited to place any movable objects during the lifting of the fourth hull 4, so as to prevent the fourth hull 4 from overturning. When the fourth hull 4 is assembled with the third hull 3, the water excavator is used to assist in leveling as much as possible, and the crane is not used to directly lift the third hull 3 and the fourth hull 4, so as to prevent the crane from being overloaded and overturned or the hull from being overturned.

[0057] S3, the second hull 2 is connected with the third hull 3 by using the positioning component.

[0058] Specifically, the second hull 2 is placed on the inside of the third hull 3 and is aligned front and back, the water excavator is used to assist in aligning the head and tail of the third hull 3 and the second hull 2, the adjacent two top plates 9 are correspondingly matched, the adjacent two bottom plates 10 are correspondingly matched, the positioning plate 11 is correspondingly inserted between the top plate 9 and the bottom plate 10, and the positioning pin 12 is vertically penetrated through the top plate 9, the positioning plate 11 and the bottom plate 10, so that the preliminary alignment of the second hull 2 and the third hull 3 is realized.

[0059] Wherein, the third hull 3 and the second hull 2 are connected, it is strictly forbidden to directly put hands into the joint of the third hull 3 and the second hull 2, and tools must be used for adjustment, and it is strictly forbidden to place any movable objects during lifting the second hull 2, so as not to cause the second hull 2 to overturn. When the second hull 2 and the third hull 3 are assembled, water excavators are used as much as possible to assist in leveling, and the third hull 3 and the second hull 2 cannot be leveled by directly lifting by the crane, so as to avoid the crane being overloaded and overturned or the hull being overturned.

[0060] S4, the first hull 1 and the second hull 2 are connected by using the positioning component, and the fifth hull 5 and the fourth hull 4 are connected.

[0061] Specifically, the first hull 1 is lifted and placed inside the second hull 2 and aligned front and back, water excavators are used to assist in aligning the head and tail of the first hull 1 and the second hull 2, the adjacent two top plates 9 are correspondingly matched, the adjacent two bottom plates 10 are correspondingly matched, the positioning plate 11 is correspondingly inserted between the top plate 9 and the bottom plate 10, and the positioning pin 12 is vertically penetrated through the top plate 9, the positioning plate 11 and the bottom plate 10, so as to realize the preliminary alignment of the second hull 2 and the first hull 1.

[0062] Wherein, the first hull 1 and the second hull 2 are connected, it is strictly forbidden to directly put hands into the joint of the first hull 1 and the second hull 2, and tools must be used for adjustment, and it is strictly forbidden to place any movable objects during lifting the second hull 2, so as not to cause the second hull 2 to overturn. When the second hull 2 and the first hull 1 are assembled, water excavators are used as much as possible to assist in leveling, and the first hull 1 and the second hull 2 cannot be leveled by directly lifting by the crane, so as to avoid the crane being overloaded and overturned or the hull being overturned.

[0063] Meanwhile, the fifth hull 5 and the fourth hull 4 are connected in the above lifting manner.

[0064] S5, a plurality of horizontal pins are inserted horizontally into the inside of the assembled hull, and a vertical pin 7 is inserted into a plurality of clamping grooves 6.

[0065] Specifically, after the first hull 1, the second hull 2, the third hull 3, the fourth hull 4 and the fifth hull 5 are preliminarily assembled and connected, the assembled hull is rotated by 90 degrees, so that the assembled hull is perpendicular to the wharf, and water excavators are used to assist in positioning, and the cables are tied on the wharf side to prevent the assembled hull from moving.

[0066] I. After the hull is positioned, the hull is leveled. If there is a large height difference between the first hull 1, the second hull 2, the third hull 3, the fourth hull 4 and the fifth hull 5, the leveling is needed by using auxiliary pressing methods such as excavators. If necessary, temporary spot welding is performed at the gap to facilitate the smooth insertion of the cross pin. The crane lifts the cross pin and aligns it with the cross pin hole of the hull. The workers on the boat observe and assist the alignment. At the beginning, the crane moves the cross pin, and the cross pin is slowly inserted into the cross pin hole. When the crane cannot move the cross pin, the water excavator is used for auxiliary pushing. After loosening the crane and moving the lifting point, the water excavator is used for pushing.

[0067] If the cross pin is successfully pushed into the cross pin hole of the hull, the first hull 1, the second hull 2, the third hull 3, the fourth hull 4 and the fifth hull 5 are assembled in the correct position without the need for additional adjustment. The multiple cross pins are sequentially inserted into the multiple cross pin holes. After the cross pin is inserted into position, the locking ring is used to sequentially lock the two ends of the multiple cross pins. Before locking the locking ring, the flatness of the hull is checked. After the locking ring is locked, the flatness is checked again.

[0068] When the cross pin is inserted into the cross pin hole, if it is blocked, it cannot be forced to push in. The cause needs to be found. Generally, there is a height difference at the joint. After adjusting the hull, the cross pin is inserted again. The water operation labor protection articles such as life jackets must be worn in place to prevent the risk of falling into the water.

[0069] II. After the cross pin is inserted, the hull is checked to see if there is any abnormal deviation or foreign matter in the card slot 6. After the cross pin is inserted, the hull should be flat without height difference. If there is, the cause needs to be found or the foreign matter needs to be removed, and the flatness of the hull needs to be adjusted. The crane lifts the vertical pin and aligns it with the top end of the card slot 6. The crane slowly lowers the vertical pin 7 until the vertical pin 7 cannot enter the card slot 6 by gravity. At this time, the water excavator can be used to slowly press the vertical pin 7 into the card slot 6. The vertical pin 7 can be inserted in sequence or alternately according to the site conditions during the vertical insertion.

[0070] S6, install pile sleeve, rake rod, steel pile, steel wire rope, vertical pile and vertical pile on the top of the assembled hull.

[0071] I. Two pile sleeves are sequentially hoisted and placed in the pile hole position, and the screws are tightened. The first installation of the pile sleeve has been positioned. The second installation of the pile sleeve generally does not need to be adjusted. When installing the pile sleeve, if the pile sleeve is found to be deformed too much to be accurately aligned, it needs to be adjusted before installation.

[0072] II. Hoist the left and right harrow bars in turn and insert the pin shaft. The first installation of the harrow bar has been adjusted and positioned, and the second installation of the harrow bar generally does not need to be adjusted. After the pin shaft is inserted, slowly lower the harrow bar to the ground and lay it on both sides of the assembled ship body with the harrow bar facing the bow direction. If the harrow bar is found to be deformed too much during installation, it needs to be adjusted and then installed. Visually check whether the welding opening and other parts are open or severely worn, find out the reasons and eliminate them before installation.

[0073] III. Hoist the left and right steel piles in turn and insert the pin shaft into the pin hole. After the pin shaft is inserted, slowly lower the steel pile to the ground and lay it on both sides of the assembled ship body with the steel pile facing the stern direction. The first installation of the steel pile has been adjusted and positioned, and the second installation of the steel pile generally does not need to be adjusted. During installation, check whether the pin shaft, pin hole and other parts are abnormally worn or deformed, and then install them after elimination. Check whether the upper and lower pulleys are abnormally worn, jammed or the like, and then install them after elimination.

[0074] IV. Check whether the pulley blocks on the steel piles and harrow bars are normal. After determining that the pulley blocks are normal and not jammed or damaged, fix the wire rope head at the outer side of the middle pulley block of the steel pile, then pass it through the inside of the top pulley block of the harrow bar, and repeat the process until the wire rope passes through all the pulley blocks. Finally, pass the wire rope through the lower two pulley blocks of the pile sleeve and fix the end of the wire rope to the pile lifting winch. The pile lifting winch does not need to be disassembled and installed again after the first installation, so it is not described here.

[0075] During installation of the pulley blocks, check whether the pulleys and pulley blocks are abnormally worn or jammed, and then install them after elimination. The wire rope must be strictly arranged according to the specified sequence, and cannot be skipped or arranged in the wrong order, otherwise the wire ropes will be pressed, crossed or tangled with each other.

[0076] V. Check whether the pulley blocks of the steel piles and harrow bars and the wire ropes are normal and securely fixed. Slowly rotate the winch to tighten the pile lifting wire rope, collect all the excess wire rope on the drum, and stop when the harrow bar and steel pile are slightly stressed. Check again whether the wire ropes, pulley blocks and other parts are pressed, crossed or jammed. After everything is normal, slowly start the winch to pull up the harrow bar. Stop the winch after the harrow bar is pulled up, insert the harrow bar safety pin, and fix the two wind-resistant cables at the top of the harrow bar to the bow fixed position. After the wind-resistant cables of the harrow bar are securely fixed, start the winch to slowly tighten the wire rope. At this time, the steel pile will be pulled up. Stop the winch and observe whether the posture of the steel pile is normal. If not, adjust the angle of the harrow bar. Insert the steel pile safety pin after the problem is solved.

[0077] During pile lifting, observe the postures and stresses of the harrow bar, steel pile, winch, wire rope and wind-resistant cable at any time. Stop immediately if any abnormality is found. No one is allowed to stand in the areas of the steel pile, harrow bar and winch.

[0078] Six, check the left and right steel piles and pulley blocks and steel wire rope, etc. are normal, no winding, rope, etc., observe the stress of the pile pin, slowly point the winch to make the pile pin not under the weight of the steel pile pressure, then pull out the pin shaft, after the pin shaft is taken out, slowly drop the steel pile until the steel pile falls to the ground, the steel wire rope is no longer under stress, after the steel pile falls to the ground, the pile supporting roller is installed in turn, and the safety pin at both ends is locked.

[0079] Among them, when the pile is lifted and dropped, the observation of the steel wire rope and the surrounding release part and the wear condition should be focused on. The steel wire rope should not be worn around the parts. When the winch steel wire rope is under stress, people are strictly prohibited from standing on both sides of the steel wire rope and crossing the steel wire rope.

[0080] Seven, check if there are sundries on the assembled ship body top surface, clean up and then place the living cabin and the driver's room. Focus on checking if the external cable and plug are damaged. The first installation position of the living cabin and the driver's room has been fixed and does not need to be adjusted. Other auxiliary equipment such as the anchor machine does not need to be removed after the first installation.

[0081] S7, install excavator on the assembled ship body top.

[0082] One, check and prepare before assembly:

[0083] Before installing the excavator, the excavator needs to be checked and prepared. The main parts of the excavator include the center platform, the rotating platform, the engine room, the counterweight, the driver's room seat, the driver's room, the left side passage, the large arm, the small arm, the bucket, and other accessories.

[0084] Among them, check if all parts are complete and intact. Check if all installation tools and equipment are complete. The base is a key structure that bears a huge dynamic load, and any defects must be handled.

[0085] Two, install the center platform and the support frame:

[0086] Check if the center platform and the support frame connection bolt torque is normal, whether it is loose or falls off, etc. The center platform, support frame and ship body are fully welded during the first installation. After disassembly, it needs to be installed again. It is necessary to observe the damage to the support frame during the first disassembly. If there is destructive disassembly, it needs to be restored before being combined with the assembled ship body. After positioning, the center platform, support frame and ship body are combined firmly. It is recommended to be fully welded.

[0087] Among them, since the stress point of the support frame is basically at the edge of the third ship body 3 and the fourth ship body 4, it is necessary to observe the influence on the assembled ship body during the last use, whether there is a large deformation, etc. Observe the weld condition of the last time, whether there is cracking, fracture, etc. old injury, find out if it is caused by process or base support frame stress design, whether it needs special treatment, etc. After full welding, according to the stress condition of the last time, the key parts are appropriately reinforced.

[0088] Three, the installation of the turntable:
