Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and particularly relates to an overall sliding and sea-going system and a sea-going method for a large jacket in a factory. Background Art

[0002] In the construction of the lower structure of a bridge, the support piles of a drilling platform are generally directly inserted by a pile driving boat. This scheme requires that the support piles can be self-stabilized under the action of waves and swells. For deep water areas without overburden or with shallow overburden, when the direct insertion of support piles cannot be self-stabilized, a platform scheme of jacket + support columns is often adopted. The existing manufacturing and installation processes of jackets are generally as follows:

[0003] (1) Unit components are fabricated in a factory, and then the unit components are transported to the bridge site for on-site assembly and then lowered. This method requires on-site scattered assembly, with extremely low construction efficiency, and occupies on-site resources such as site and equipment. In addition, the scattered assembly method has low accuracy and cannot accurately guarantee the overall linear shape of the jacket.

[0004] (2) The jacket is integrally manufactured and assembled in a factory. After assembly, it is disassembled into small units and transported to the dock by hoisting equipment and transport flat cars for hoisting onto the ship. This method is limited by the lifting capacity of the hoisting equipment and requires the jacket to be disassembled into many small units. When the number of disassembled units is too large, it still increases the on-site assembly workload and affects the linear shape of the jacket. In addition, transport flat cars need to be equipped, increasing the input cost. Summary of the Invention

[0005] Aiming at the above deficiencies in the prior art, the present invention provides an overall sliding and sea-going system and a sea-going method for a large jacket in a factory, which can simply and efficiently slide the jacket to the sea, ensuring both the linearity of the jacket and cost savings, with simple operation, low equipment occupancy rate, and wide application range.

Detailed implementation manners

[0052] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific examples described herein are only used to explain the present invention and do not limit the present invention. In addition, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0054] As Figure 1 and Figure 7As shown in the figure, a large jacket integral slip-out-to-sea system in a factory includes an orbital subsystem and a slip subsystem. The orbital subsystem includes a plurality of longitudinally moving tracks 1 and transversely moving tracks 3 that are perpendicular and intersecting with each other. The slip subsystem includes a plurality of longitudinally moving sliders 2 arranged on the longitudinally moving tracks 1, a plurality of transversely moving sliders 4 arranged on the transversely moving tracks 3, and a plurality of pushing devices 5 for pushing the longitudinally moving sliders 2 and the transversely moving sliders 4 to slip. A limiting member (not shown in the figure) is detachably provided between the transversely moving slider 4 and the longitudinally moving track 1, and a clamping structure is provided in cooperation on the longitudinally moving slider 2 and the transversely moving slider 4.

[0055] The longitudinally moving slider 2 is used to slip along the longitudinally moving track 1 under the action of the pushing device 5, and the transversely moving slider 4 is used to slip along the transversely moving track 3 under the action of the pushing device 5. Specifically, after assembling the jacket 6 on the longitudinally moving track 1, the jacket 6 is installed on the longitudinally moving slider 2, and the longitudinally moving slider 2 is slipped to the front of the transversely moving track 3 and the transversely moving slider 4 through the pushing device 5, as Figure 8 shown. The longitudinally moving slider 2 is continuously slipped along the longitudinally moving track 1 until the longitudinally moving slider 2 is located above the transversely moving slider 4. At this time, the longitudinally moving slider 2 and the transversely moving slider 4 are connected into one body through the clamping structure, and the jacket 6 is always located on the longitudinally moving slider 2. The transversely moving slider 4 is again slipped along the transversely moving track 3 through the pushing device 5 until it reaches the sea-out position, and then subsequent unit disassembly and hoisting onto the ship are carried out. When the longitudinally moving slider 2 slips to the front of the transversely moving slider 4, a limiting member is provided between the transversely moving slider 4 and the longitudinally moving track 1, and the transversely moving slider 4 is tightened by the limiting member to prevent the longitudinally moving slider 2 from dragging the transversely moving slider 4 when the longitudinal movement is in place. After the jacket 6 is longitudinally moved onto the transversely moving slider 4, the limiting member is removed.

[0056] In this embodiment, the assembly of the jacket 6 can be directly completed on the longitudinally moving track 1, without the need to be equipped with large hoisting equipment or transportation flat cars in the factory, without occupying too much on-site space and equipment and other resources, and saving the input cost.

[0057] During the process of transporting the assembled jacket 6 to the sea-out position, the integrity is high. When the jacket units are disassembled at the sea-out position, there is no need to consider the lifting weight limit in the factory, and the unit division can be carried out according to the lifting capacity of the construction site hoisting, which greatly improves the on-site assembly speed and assembly accuracy, and the safety risk is low.

[0058] The connection at the intersection of the longitudinally moving track 1 and the transversely moving track 3 is smoothly connected. After the longitudinal movement of the jacket 6 is in place, the transverse movement process can be directly carried out. The operation is simple and efficient. The longitudinally moving track 1, the transversely moving track 3, and the longitudinally moving sliders 2 and transversely moving sliders 4 provided thereon can be set according to different jacket units, and the applicable range is wider.

[0059] In a preferred embodiment, the number of longitudinal moving tracks 1 and transverse moving tracks 3 is not less than two. Generally, the number of longitudinal moving tracks 1 is greater than that of transverse moving tracks 3. The number of pushing devices 5 is the same as that of longitudinal moving tracks 1. When used for longitudinally sliding the longitudinal moving slider 2, the pushing devices 5 are arranged on the longitudinal moving tracks 1. When used for transversely sliding the transverse moving slider 4, the pushing devices 5 are removed from the longitudinal moving tracks 1 and installed on the transverse moving tracks 3. The number of longitudinal moving tracks 1, transverse moving tracks 3, longitudinal moving sliders 2, transverse moving sliders 4, and pushing devices 5 can be designed according to actual needs, which is flexible and convenient.

[0060] In a preferred embodiment, as Figure 4 shown, the longitudinal moving track 1 includes two first I-beams 10 arranged in parallel and two first welding pieces 11 welded between the two first I-beams 10. The two first I-beams 10 are arranged in parallel on the sleepers, and the thickness of the two first welding pieces 11 is the same as the flange thickness of the first I-beams 10. The first welding piece 11 located at the upper end is welded between the top flanges of the two first I-beams 10, and its top surface is flush with the top surface of the longitudinal moving track 1 (specifically, flush with the top surfaces of the two first I-beams 10, and polished smoothly after welding for the smooth sliding of the longitudinal moving slider 2); the first welding piece 11 located at the lower end can be directly welded on the bottom flanges of the two first I-beams 10 for convenient construction.

[0061] The structure of the transverse moving track 3 is the same as that of the longitudinal moving track 1. The transverse moving track 3 includes two second I-beams (not shown in the figure) arranged in parallel and two second welding pieces (not shown in the figure) welded between the two second I-beams. The second welding piece located at the upper end is welded between the top flanges of the two second I-beams, and its top surface is flush with the top surface of the transverse moving track 3; the second welding piece located at the lower end is welded on the bottom flanges of the two second I-beams.

[0062] The transverse moving track 3 is vertically arranged at the end of the longitudinal moving track 1, and the longitudinal and transverse moving tracks are arranged according to the positional relationship between the jacket processing plant and the slip-out sea terminal. The structure of the transverse moving track 3 is the same as that of the longitudinal moving track 1, and the top elevation of the transverse moving track 3 is lower than that of the longitudinal moving track 1, so that the longitudinal moving slider 2 can always slide from the longitudinal moving track 1 to above the transverse moving slider 4 located on the transverse moving track 3.

[0063] In a preferred embodiment, as Figure 2 and Figure 6 shown, the longitudinal moving slider 2 includes a longitudinal distribution beam 20 arranged along the longitudinal moving track 1, a first transverse distribution beam 21 vertically connected to the longitudinal distribution beam 20, a plurality of first stiffening plates 24 connected between the longitudinal distribution beam 20 and the first transverse distribution beam 21, a first top seat 22 connected to one side of the longitudinal distribution beam 20, and a first guiding and limiting assembly 23 connected to the bottom of the longitudinal distribution beam 20.

[0064] The longitudinal distribution beam 20 and the first transverse distribution beam 21 are used to carry the jacket 6. The longitudinal distribution beam 20 is welded below the steel pipe piles of the jacket 6 along the longitudinal movement track 1, and its length is slightly greater than the pile spacing of the steel pipe piles. The first transverse distribution beam 21 is perpendicularly welded below the steel pipe piles of the jacket 66 and perpendicular to the longitudinal distribution beam 20. At the same time, the first stiffening plate 24 is welded between the bottom of the steel pipe pile and the longitudinal distribution beam 20, and between the bottom of the steel pipe pile and the first transverse distribution beam 21.

[0065] The first top seat 22 is welded on the side of the longitudinal distribution beam 20 away from the sliding forward direction, and a pin hole for connecting the jack 52 is provided on the first top seat 22.

[0066] The first guiding and limiting assembly 23 is used for laterally limiting the longitudinal movement slider 2. It includes a first top plate 230 connected to the bottom of the longitudinal distribution beam 20, two first baffle plates 231 respectively connected to both sides of the bottom of the first top plate 230, first side plates 232 respectively connected to both sides of the first top plate 230, a first stainless steel plate 233 connected to the bottom of the first top plate 230 and located between the two first baffle plates 231, and a first sliding plate 234 connected to the bottom of the first stainless steel plate 233 and located between the two first baffle plates 231. Among them, the first baffle plate 231 is perpendicularly welded to the lower end of the first top plate 230 and is located on both sides of the longitudinal movement track 1 to ensure that the entire longitudinal movement slider 2 always moves along the longitudinal movement track 1. Both ends of the first baffle plate 231 are bent away from the longitudinal movement track 1 to prevent jamming between the longitudinal movement slider 2 and the longitudinal movement track 1 during sliding. The first side plate 232 is welded between the outer side of the first baffle plate 231 and the upper longitudinal distribution beam 20 to enhance the lateral bending stiffness of the first baffle plate 231. The first baffle plate 231 and the first side plate 232 on the same side form a set of first limiting protrusions for laterally limiting the longitudinal movement slider 2. The first sliding plate 234 can be made of MGR material plate to reduce the sliding friction coefficient.

[0067] When the longitudinal movement slider 2 slides on the longitudinal movement track 1, the first sliding plate 234 fits with the top surface of the longitudinal movement track 1, and the first limiting protrusions located on both sides of the longitudinal movement track 1 clamp the longitudinal movement track 1 to achieve lateral limitation.

[0068] In a preferred embodiment, as Figure 3 and Figure 9 shown, the transverse movement slider 4 includes a second transverse distribution beam 40 arranged along the transverse movement track 3, a second top seat 41 connected to one side of the transverse distribution beam 40, and a second guiding and limiting assembly 42 connected to the bottom of the second transverse distribution beam 40.

[0069] The second guiding and limiting component 42 includes a second top plate (not shown in the figure) connected to the bottom of the second transverse distribution beam 40, two second baffle plates (not shown in the figure) respectively connected to both sides of the bottom of the second top plate, second side plates (not shown in the figure) respectively connected to both sides of the second top plate, a second stainless steel plate (not shown in the figure) connected to the bottom of the second top plate and located between the two second baffle plates, and a second sliding plate (not shown in the figure) connected to the bottom of the second stainless steel plate and located between the two second baffle plates. Among them, the second baffle plates are vertically welded to the lower end of the second top plate and are located on both sides of the transverse movement track 3 to ensure that the entire transverse movement slider 4 always moves along the transverse movement track 3. The two ends of the second baffle plates are bent away from the transverse movement track 3 to prevent jamming between the transverse movement slider 4 and the transverse movement track 3 during sliding. The second side plates are welded between the outer sides of the second baffle plates and the upper second transverse distribution beam 40 to enhance the lateral bending resistance stiffness of the second baffle plates. The second baffle plate and the second side plate on the same side form a set of second limiting protrusions for laterally limiting the longitudinal movement slider 2. The second sliding plate can be made of MGR material plate to reduce the sliding friction coefficient.

[0070] When the transverse movement slider 4 slides on the transverse movement track 3, the second sliding plate fits with the top surface of the transverse movement track 3, and the second limiting protrusions located on both sides of the transverse movement track 3 clamp the transverse movement track 3 to achieve longitudinal limiting.

[0071] Two avoidance grooves 400 are provided at the top of the second transverse distribution beam 40, and the avoidance grooves 400 and the first limiting protrusions at the opposite positions form the clamping structure. In addition to laterally limiting the longitudinal movement slider 2 during longitudinal sliding, the above-mentioned first limiting protrusions can also be clamped with the avoidance grooves 400 when the longitudinal movement slider 2 slides above the transverse movement slider 4. After the longitudinal movement slider 2 and the transverse movement slider 4 are clamped together, they can slide along the transverse movement track 3 together under the drive of the pushing device 5.

[0072] In a preferred embodiment, as Figure 5 shown, the pushing device 5 includes a reaction seat 50 arranged on the track subsystem, a clamping plate 51 detachably installed in the reaction seat 50, and a jack 52. Vertical plates 53 are also provided on both sides of the reaction seat 50 to prevent the reaction seat 50 from shifting laterally during the pushing process. A rectangular through groove (not shown in the figure) is provided in the middle of the reaction seat 50, and the clamping plate 51 is a rectangular steel plate with the same width as the width of the through groove. When the jack 52 pushes, the clamping plate 51 is installed in the through groove, and when the jack 52 pulls back, the clamping plate 51 is taken out of the through groove.

[0073] When used to slide the longitudinal movement slider 2, the reaction seat 50 is arranged on the longitudinal movement track 1, and one end of the jack 52 is connected to the reaction seat 50 and the other end is connected to the first top seat 22.

[0074] When used to slide the transverse movement slider 4, the reaction seat 50 is arranged on the transverse movement track 3, and one end of the jack 52 is connected to the reaction seat 50 and the other end is connected to the second top seat 41.

[0075] The limiting member is made of a third I-beam, which is welded between the transverse sliding block 4 and the longitudinal moving track 1 and has the same top surface level as the longitudinal moving track 1.

[0076] Taking the longitudinal pushing as an example, insert the clamping plate 51 into the rectangular through groove into the longitudinal sliding track 1 and abut against the upper first welding piece 11. Through the limitation of the clamping plate 51 by the first welding piece 11, the pushing reaction force is provided. When the jack 52 reaches the specified position, pull out the clamping plate 51, the oil pump returns oil, the jack 52 retracts and drives the reaction seat 50 forward, and then insert the clamping plate 51 again to continue pushing forward. When pushing laterally, the working principle of the jack is the same as that in longitudinal pushing.

[0077] Such as Figure 1 and Figure 10 shown, a method for the overall sliding of a large jacket factory to the sea includes:

[0078] Step S1, arrange a plurality of longitudinally moving tracks 1 and transversely moving tracks 3 that are perpendicular and staggered with each other between the jacket processing factory and the sea-going wharf to form a track subsystem. A longitudinal sliding block 2 is installed on each longitudinal moving track 1, and a transverse sliding block 4 is installed on each transverse moving track 3.

[0079] Step S2, assemble the members of the jacket 6 on the track subsystem, install the assembled jacket 6 on the longitudinal sliding block 2, and respectively install a pushing device 5 on the corresponding longitudinal moving track 1. All the pushing devices 5 are located on the same side of the jacket 6. Install a jack 52 between the pushing device 5 and the longitudinal sliding block 2 on the same longitudinal moving track 1. Simultaneously push the multiple longitudinal sliding blocks 2 carrying the jacket 6 through a plurality of jacks 52 until the jacket 6 slides to the designed longitudinal position.

[0080] Step S3, set a limiting member between the transverse sliding block 4 and the longitudinal moving track 1 to fix the transverse sliding block 4, and simultaneously push the multiple longitudinal sliding blocks 2 carrying the jacket 6 through a plurality of jacks 52 until the limiting member is removed above the corresponding transverse sliding block 4.

[0081] Step S4, remove the pushing devices 5 with the same number as the transverse moving tracks 3 from the longitudinal moving tracks 1 and install them on the transverse moving tracks 3. Install a jack 52 between the pushing device 5 and the transverse sliding block 4 on the same transverse moving track 3. Simultaneously push the multiple transverse sliding blocks 4 carrying the jacket 6 through a plurality of jacks 52 until the jacket 6 slides to the sea-going position.

[0082] When pushing through the jack 52, monitor the degree of the jack 52 and the sliding distance through the monitoring equipment.

[0083] In this embodiment, the assembly of the jacket 6 can be directly completed on the longitudinal movement track 1 and transported to the sea-going position, which can simply and efficiently slide the jacket 6 out to sea, ensuring both the linearity of the jacket and cost savings. The operation is simple, the equipment occupancy rate is low, and the applicable range is wide.

[0084] The present invention is not limited to the above embodiments. For those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as within the protection scope of the present invention. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
