Description

Technical Field

[0001] The present disclosure belongs to the technical field of marine equipment transportation, and particularly relates to a caisson transfer system. Background Art

[0002] A caisson is a precast structure used in underwater foundation engineering and is widely used in the construction of bridges, wharves, ports, and other large underwater structures. A caisson is a box-shaped structure with a top but no bottom, and internal partitions are provided so that it can float in water.

[0003] In the related art, the manufacture of caissons is usually carried out in a dedicated precast site. After the caissons are manufactured, they are transported to the waters near the construction site by land transportation and then launched. During the transfer, they are first transported to the shore by special transport vehicles, and then hoisted into a lifting ship by a crane or the like. Finally, the lifting ship is controlled to immerse the caisson in seawater to float automatically and separate from the lifting ship.

[0004] However, during the caisson transfer process, due to its large volume and weight, the loading and unloading processes are complex, requiring high-precision operations and a large amount of manpower and material resources. At the same time, a large site area is required and the operation is slow. Using a lifting ship for launching not only has a high cost and complex operation, but also there will be an eccentric load during the process of hoisting the caisson onto the lifting ship, and the control process is complex. Summary of the Invention

[0005] An embodiment of the present disclosure provides a caisson transfer system, which can simplify the caisson transfer process. The technical solution is as follows:

[0006] An embodiment of the present disclosure provides a caisson transfer system, which includes a land transfer unit and a launching transfer unit. The land transfer unit includes a transfer trolley and a transfer track. The transfer trolley can move along the transfer track on the transfer track, and the top of the transfer trolley is used to support the caisson to be transferred. The launching transfer unit includes a lifting platform, a plurality of support seats, and a lifting driving device. The lifting platform is arranged on the water surface near the shore, and there is a platform track in the lifting platform. One end of the platform track is docked with the transfer track. The plurality of support seats are spaced on the same platform surface of the lifting platform and are all connected to the lifting platform. The plurality of support seats are used to support the caisson to be transferred after the transfer trolley enters the platform track, so that the caisson to be transferred can be separated from the transfer trolley. The lifting driving device is connected to the lifting platform and is used to drive the lifting platform to lift and enter the seawater.

[0007] In another implementation manner of the present disclosure, at least one section of the transfer track is a straight track, the platform track is a straight track, and the straight track in the transfer track and the platform track are on the same straight line.

[0008] In yet another implementation of the present disclosure, the transfer track includes a linear transverse track and a linear longitudinal track, the transverse track and the longitudinal track are perpendicular to each other, and one of the transverse track and the longitudinal track is docked with the platform track.

[0009] In another implementation of the present disclosure, the transverse track and the longitudinal track each include two sub-tracks parallel to each other; each of the sub-tracks has a break in the middle, and the break in the transverse track and the break in the longitudinal track together define an installation space; the transfer track also includes a buffer track, which is located in the installation space, and the buffer track is respectively connected to the two sub-tracks in the transverse track and the two sub-tracks in the longitudinal track, and the buffer track is used to enable the transfer trolley to move along the crossed transverse track or the longitudinal track.

[0010] In another implementation of the present disclosure, the buffer track includes four buffer units and four buffer blocks, two of the four buffer units are arranged in one-to-one correspondence with the two sub-tracks of the transverse track, and the other two buffer units are arranged in one-to-one correspondence with the two sub-tracks of the longitudinal track; each of the buffer units is located on a straight line where the corresponding sub-track is located, and the buffer unit includes three connecting blocks arranged in sequence and at intervals along the length direction of the corresponding sub-track, and the two connecting blocks located on both sides are respectively connected to the corresponding sub-tracks; four installation sub-spaces are respectively formed between the buffer units corresponding to the sub-tracks in the transverse track and the buffer units corresponding to the sub-tracks in the longitudinal track, and each of the installation sub-spaces is respectively located between two adjacent connecting blocks in a buffer unit; the four buffer blocks correspond to the four installation sub-spaces in one-to-one correspondence, each of the buffer blocks is located in the corresponding installation sub-space, and there is a gap between the buffer block and the adjacent connecting block for the wheel rim of the wheel of the transfer trolley to pass through.

[0011] In another implementation of the present disclosure, the top of the transfer vehicle can be raised and lowered relative to its bottom, and after the transfer vehicle enters the lifting platform, the caisson to be transferred is located directly above the support seat.

[0012] In another implementation of the present disclosure, the launching transfer unit also includes a guide plate, which is located on the side of the lifting platform, and the guide plate has at least one guide groove that cooperates with the shore, and the length direction of the guide groove is the lifting direction of the lifting platform.

[0013] In yet another implementation of the present disclosure, the side of the guide plate facing the shore has a plurality of teeth, and a guide groove is defined between two adjacent teeth of the guide plate; a shore tooth plate meshing with the guide plate is provided on the shore.

[0014] In yet another implementation of the present disclosure, the caisson transfer system further includes a limiting assembly, and the limiting assembly is used to be connected to the lifting platform to limit the lifting platform on the shore when the transfer trolley drives into the lifting platform.

[0015] In yet another implementation of the present disclosure, the limiting assembly includes a plurality of corresponding pins and a plurality of pin cylinders. The pin cylinders are connected to one end of the corresponding pins, and the other end of the pins is used to be connected to the lifting platform. The length direction of the pins is perpendicular to the lifting direction of the lifting platform; along the length direction of the pins, the two pins are respectively located on opposite sides of the lifting platform.

[0016] The beneficial effects brought by the technical solutions provided by the embodiments of the present disclosure are as follows:

[0017] When the caisson transfer system provided by the embodiments of the present disclosure is used to transfer the fabricated caisson, since the caisson transfer system includes a land transfer unit and a water transfer unit, the fabricated caisson can be transferred from the fabrication site to the shore by the land transfer unit, and the caisson moved to the shore can be lowered into the sea water by the water transfer unit.

[0018] Since the land transfer unit includes a transfer trolley and a transfer track, and the transfer trolley can move along the transfer track on the transfer track, and the top of the transfer trolley is used to support the caisson to be transferred, the transfer trolley can be controlled to move to the bottom of the caisson to lift the caisson from the prefabrication site through the top of the transfer trolley. Then, continue to control the transfer trolley to move in the transfer track so that the transfer trolley can carry the caisson to move and the caisson moves to the shore.

[0019] At the same time, since the water transfer unit includes a lifting platform, and there is a platform track on the lifting platform, and one end of the platform track is used to be docked with the transfer track, when the transfer trolley moves in the transfer track, it can drive into the lifting platform.

[0020] Since the water transfer unit further includes a plurality of support seats, and the plurality of support seats are used to support the caisson to be transferred after the transfer trolley drives into the lifting platform, when the transfer trolley moves into the platform track, the plurality of support seats can support the caisson. At this time, just move the transfer trolley away to make the caisson be supported by the support seats and the caisson is located on the lifting platform.

[0021] Since the underwater transfer unit further includes a lifting drive device, and the lifting drive device is connected to the lifting platform, the lifting drive device can drive the lifting platform to lift and lower into the sea water. Therefore, after the transfer trolley is located on the lifting platform, the lifting drive device can be controlled to drive the lifting platform to move downward, and then lower it into the water. In this way, the caisson on the lifting platform will move downward and enter the water together. When the lifting platform enters the water, since the caisson is only supported by the support seat, the caisson will automatically separate from the lifting platform under the buoyancy of the water and float on the water surface.

[0022] Since the caisson transfer system provided by the embodiments of the present disclosure only needs to control the movement of the transfer trolley and the lifting of the lifting platform during the entire transfer process of the caisson, the transfer process is greatly simplified and the transfer efficiency is improved.

[0034] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0035] The embodiments of the present disclosure provide a caisson transportation system for transferring a caisson from the caisson manufacturing site into the water.

[0036] Figure 1 Shown is a schematic structural diagram of a caisson transportation system provided by an embodiment of the present disclosure. In combination with Figure 1 , the caisson transportation system includes a land transportation unit 1 and a launch transportation unit 2. The land transportation unit 1 includes a transportation trolley 11 and a transportation track 12. The transportation trolley 11 can move along the transportation track 12 on the transportation track 12. The top of the transportation trolley 11 is used to support the caisson to be transported.

[0037] The launch transportation unit 2 includes a lifting platform 21, a plurality of support bases 22, and a lifting drive device 23. The lifting platform 21 is arranged on the water surface of the shore, and the lifting platform 21 is provided with a platform track 211. One end of the platform track 211 is used to be docked with the transportation track 12 so that the transportation trolley 11 can drive onto the lifting platform 21. The plurality of support bases 22 are all spaced apart on the same platform surface of the lifting platform 21 and are all connected to the lifting platform 21. The plurality of support bases 22 are used to support the caisson to be transported after the transportation trolley 11 drives onto the lifting platform 21, so that the caisson to be transported can be separated from the transportation trolley 11. The lifting drive device 23 is connected to the lifting platform 21 and is used to drive the lifting platform 21 to lift and lower into the sea water.

[0038] When the caisson transfer system provided by the embodiments of the present disclosure is used to transfer the fabricated caisson, since the caisson transfer system includes an onshore transfer unit 1 and an offloading transfer unit 2, the fabricated caisson can be transferred from the fabrication site to the shore by the onshore transfer unit 1, and the caisson moved to the shore can be lowered into the sea water by the offloading transfer unit 2.

[0039] Since the onshore transfer unit 1 includes a transfer trolley 11 and a transfer track 12, and the transfer trolley 11 can move along the transfer track 12 on the transfer track 12, and the top of the transfer trolley 11 is used to support the caisson to be transferred, it is possible to control the transfer trolley 11 to move to the bottom of the caisson, so as to lift the caisson from the prefabrication site through the top of the transfer trolley 11. Then, continue to control the transfer trolley 11 to move in the transfer track 12, so that the transfer trolley 11 can carry the caisson to move, so that the caisson moves to the shore.

[0040] At the same time, since the offloading transfer unit 2 includes a lifting platform 21, and there is a platform track 211 on the lifting platform 21, and one end of the platform track 211 is used to be docked with the transfer track 12, when the transfer trolley 11 moves in the transfer track 12, it can drive into the lifting platform 21.

[0041] Since the offloading transfer unit 2 further includes a plurality of support seats 22, and the plurality of support seats 22 are used to support the caisson to be transferred after the transfer trolley 11 drives into the lifting platform 21, when the transfer trolley 11 moves into the platform track 211, the plurality of support seats 22 can support the caisson. At this time, as long as the transfer trolley 11 is removed, the caisson can be supported by the support seats 22 to realize that the caisson is located on the lifting platform 21.

[0042] Since the offloading transfer unit 2 further includes a lifting drive device 23, and the lifting drive device 23 is connected to the lifting platform 21, and the lifting drive device 23 can drive the lifting platform 21 to lift and lower into the water, when the transfer trolley 11 is located on the lifting platform 21, the lifting drive device 23 can be controlled to drive the lifting platform 21 to move downward, and then lower it into the water. In this way, the caisson on the lifting platform 21 will move downward and enter the water together. After the lifting platform 21 enters the water, since the caisson is only supported by the support seats 22, the caisson will automatically fall off the lifting platform 21 under the buoyancy of the water and float on the water surface.

[0043] Since the caisson transfer system provided by the embodiments of the present disclosure only needs to control the movement of the transfer trolley 11 and the lifting of the lifting platform 21 during the entire transfer process of the caisson, the transfer device is greatly simplified and the transfer efficiency is improved.

[0044] Continue to refer to Figure 1Optionally, at least one section of the transfer track 12 is a straight track, and the platform track 211 is a straight track, and the straight track and the platform track 211 are located on the same straight line.

[0045] In the above implementation, at least one section of the transfer track 12 is set as a straight track, and the platform track 211 is set as a straight track, so that the transfer track 12 and the platform track 211 are conveniently connected together, thereby facilitating the transfer trolley 11 to move on the lifting platform 21.

[0046] In the disclosed embodiment, in order to facilitate the control of the direction of the transfer vehicle 11, the transfer track 12 is a straight track. The transfer track 12 is embedded in a tunnel in the ground. The caisson is located directly above the tunnel. In this way, when the transfer vehicle 11 travels in the transfer track 12, the caisson located on the ground can be lifted and moved together.

[0047] Figure 2 This is a schematic diagram of the structure of the transfer vehicle. Figure 2 The top of the transfer trolley 11 has a support plate 110 for supporting the caisson to be transferred. The transfer trolley 11 is equipped with a motor 112 and a jack 113. The motor 112 and the jack 113 are respectively located on opposite sides of the forward direction of the body of the transfer trolley 11, and the jack 113 is connected to the support plate 110. The transfer trolley 11 has walking and jacking capabilities. When the transfer trolley 11 is moving, by controlling the motor 112, the transfer trolley 11 can be controlled to walk in the transfer track 12, and by controlling the jack 113, the lifting and lowering of the caisson located on the support plate 110 can be controlled.

[0048] Figure 3 for Figure 1 Schematic diagram of part of the structure of the transfer track, combined with Figure 3 Optionally, the transfer track 12 includes a linear transverse track 121 and a linear longitudinal track 122, and the transverse track 121 and the longitudinal track 122 are perpendicular to each other and located in the same horizontal plane.

[0049] The transverse track 121 is connected to the longitudinal track 122 , and one of the transverse track 121 and the longitudinal track 122 is connected to the platform track 211 and is located on the same straight line.

[0050] In the above implementation, the transfer track 12 is set as a transverse track 121 and a longitudinal track 122, so that the entrances of the transfer track 12 can be located in different directions, thereby being able to transfer caissons located at different positions, greatly improving the transfer convenience and efficiency of the caisson transfer system.

[0051] Combination Figure 2, optionally, two rows of wheels 111 are provided at the bottom of the transfer trolley 11. Correspondingly, both the transverse track 121 and the longitudinal track 122 include two mutually parallel sub-tracks 1221. The wheels 111 of the same row are located on one of the sub-tracks 1221, and the rims of the wheels 111 are outside the sub-tracks 1221.

[0052] Combined with Figure 3 , a break 1200 is provided in the middle of each sub-track 1221. The break 1200 in the transverse track 121 and the break 1200 in the longitudinal track 122 together define an installation space 120.

[0053] The transfer track 12 further includes a buffer track 123. The buffer track 123 is located in the installation space 120, and the buffer track 123 is respectively connected to the two sub-tracks 1221 in the transverse track 121 and the sub-tracks 1221 in the longitudinal track 122. The buffer track 123 is used to enable the transfer trolley 11 to travel along the crossed transverse track 121 or longitudinal track 122.

[0054] In the above implementation, the presence of the break 1200 is used to arrange the buffer track 123. The buffer track 123 is used to enable the transverse track 121 and the longitudinal track 122 to be cross-connected.

[0055] Optionally, the buffer track 123 includes four buffer units 1230 and four buffer blocks 1232. Two of the four buffer units 1230 are arranged in one-to-one correspondence with the two sub-tracks 1221 of the transverse track 121, and the other two buffer units 1230 are arranged in one-to-one correspondence with the two sub-tracks 1221 of the longitudinal track 122.

[0056] Each buffer unit 1230 is located on the straight line where the corresponding sub-track 1221 is located, and the buffer unit 1230 includes three connecting blocks 1231 arranged at intervals in sequence along the length direction of the corresponding sub-track 1221. The two connecting blocks 1231 located on both sides are respectively connected to the corresponding sub-track 1221.

[0057] Four installation sub-spaces 1201 are respectively formed between the buffer units 1230 corresponding to the sub-tracks 1221 in the transverse track 121 and the buffer units 1230 corresponding to the sub-tracks 1221 in the longitudinal track 122. Each installation sub-space 1201 is respectively located between two adjacent connecting blocks 1231 in a buffer unit 1230. The four buffer blocks 1232 are in one-to-one correspondence with the four installation sub-spaces 1201. Each buffer block 1232 is located in the corresponding installation sub-space 1201, and there is a gap for the rim of the wheel of the transfer trolley 11 to pass between the buffer block 1232 and the adjacent connecting block 1231.

[0058] In the above implementation manner, each buffer unit 1230 includes three connecting blocks 1231 arranged at intervals in sequence. In this way, the gap between two adjacent connecting blocks 1231 can exactly accommodate the buffer block 1232, enabling the buffer block 1232 to connect the intersecting buffer units 1230 together, and further enabling the transfer trolley 11 to pass smoothly.

[0059] Figure 4 For Figure 3 a side view along the length direction of the longitudinal track in Figure 4 , in this embodiment, for the convenience of docking the buffer unit 1230 and the buffer block 1232, the buffer track 123 further includes a connecting plate 1233. The connecting plate 1233 is located in the installation space 120, and the two opposite sides of the connecting plate 1233 are respectively connected to the parts near the bottom of the two sub-tracks 1221 of the transverse track 121, and the other two opposite sides of the connecting plate 1233 are respectively connected to the parts near the bottom of the two sub-tracks 1221 of the longitudinal track 122. Both the buffer unit 1230 and the buffer block 1232 are connected to a plate surface of the connecting plate 1233 facing the top of the sub-track 1221.

[0060] The connecting plate 1233 can be connected to the sub-track 1221, the buffer unit 1230, and the buffer block 1232 by welding.

[0061] In the embodiment of the present disclosure, the connecting block 1231 is a long strip-shaped block. One end of the connecting block 1231 in the length direction is connected to one end of the corresponding sub-track 1221, and the width of the connecting block 1231 is not greater than the width of the top of the sub-track 1221. In this way, the bottom flange of the wheel of the transfer trolley 11 can pass through the connecting block 1231 smoothly.

[0062] Correspondingly, the buffer block 1232 is a square block, and the width of the buffer block 1232 is the same as the width of the connecting block 1231. In this way, the bottom flange of the wheel of the transfer trolley 11 can pass through the connecting block 1231 smoothly. In addition, in order to enable the buffer block 1232 and the connecting block 1231 to have sufficient strength, both the buffer block 1232 and the connecting block 1231 are metal steel structure parts.

[0063] In the embodiment of the present disclosure, there are two transverse tracks 121 and two longitudinal tracks 122. Among them, the two transverse tracks 121 are parallel to each other, and the two longitudinal tracks 122 are parallel to each other. In this way, four caissons can operate simultaneously.

[0064] In other examples, the number of the transverse track 121 and the longitudinal track 122 can be other numbers, such as three, four, etc.

[0065] In addition, in the embodiments of the present disclosure, since the production process of the caisson includes multiple processes, in order to further simplify the caisson transfer process, multiple production processes of the caisson can be arranged at intervals along the transverse track 121 or the longitudinal track 122. For example, referring to Figure 1 , the base of the caisson can be first transferred to the next process by the transfer cart 11 for positioning, and then the caisson wall is poured at this position. After the pouring is completed and the transfer structural strength requirement is met, the caisson can be transferred to the longitudinal track 122.

[0066] In addition, since the transfer cart 11 can only travel along the transverse track 121 or the longitudinal track 122, when it is necessary to transfer the transfer cart 11 from the transverse track 121 to the longitudinal track 122 or from the longitudinal track 122 to the transverse track 121, the transfer cart 11 can be transferred by a crane.

[0067] Continuing to refer to Figure 1 , optionally, since the top of the transfer cart 11 has a support plate 110 for supporting the caisson to be transferred, and the jack 113 is connected to the support plate 110. Therefore, when the transfer cart 11 drives into the lifting platform 21, the caisson to be transferred is suspended directly above the support seat 22, and then the jack 113 can be controlled to drive the support plate 110 to descend, so that the caisson to be transferred is separated from the support plate 110, and the caisson to be transferred is completely supported by the support seat 22, thereby transferring the caisson to be transferred from the support plate 110 to the support seat 22.

[0068] Exemplarily, multiple support seats 22 are arranged in two parallel columns, and a moving space for the transfer cart 11 to move is formed between the two columns of support seats 22, and the platform track 211 is located in the moving space.

[0069] The support seats 22 are arranged in two parallel columns, which is convenient for forming a moving space, and further convenient for the transfer cart 11 to travel in the lifting platform 21.

[0070] Exemplarily, the support seat 22 can be a cylindrical structure with a relatively large cross-section.

[0071] In this embodiment, there are four support seats 22. The bottoms of the four support seats 22 are all connected to the lifting platform 21.

[0072] In order to improve the structural strength of the lifting platform 21 and the support seat 22, the support seat 22 and the lifting platform 21 can be an integral structure. For example, the support seat 22 and the lifting platform 21 are integrally cast structural members. Or the support seat 22 and the lifting platform 21 are prefabricated parts formed by integral cement concrete pouring, etc.

[0073] Optionally, the lifting drive device 23 includes a winch 231 and a pulley block 232 , and the rope in the winch 231 is connected to the lifting platform 21 after being guided by the pulley block 232 .

[0074] In the above implementation, due to the large volume and weight of the caisson, the caisson located on the lifting platform 21 can be driven by the winch 231. The pulley block 232 is used to guide the rope of the winch 231 so that the rope can smoothly pull the lifting platform 21 up and down.

[0075] In other examples, the lifting drive device 23 may also be other structures, such as a crane, a lifting cylinder, etc.

[0076] In the disclosed embodiment, there may be more than one winch 231. Correspondingly, there may be more than one pulley block 232, and the pulley blocks 232 correspond to and are connected to the winches 231 one by one. The winches 231 are respectively located on opposite sides of the lifting platform 21.

[0077] Optionally, the launching and transferring unit 2 is located in a U-shaped groove on the shore. The notch of the U-shaped groove is away from the shore. The launching and transferring unit 2 also includes a guide plate 24, which is located on at least one side of the lifting platform 21 opposite to the groove wall of the U-shaped groove, and the guide plate 24 has at least one guide groove 240 that matches the shore, and the length direction of the guide groove 240 is the lifting direction of the lifting platform 21.

[0078] In the above implementation, the guide plate 24 is configured to cooperate with the U-shaped groove on the shore, so that the lifting platform 21 can move smoothly without shaking or tilting when lifting.

[0079] Optionally, there are three guide plates 24 , which are arranged in sequence along the circumference of the lifting platform 21 , and each guide plate 24 is opposite to a groove wall of the U-shaped groove. The three guide plates 24 are all connected to the lifting platform 21 .

[0080] In the above implementation, three guide plates 24 are provided to limit and guide the entire circumference of the lifting platform 21, so that the lifting platform 21 will not shake when launched into water, thereby improving the stability of the lifting platform 21.

[0081] Figure 5 Schematic diagram of the connection between the shore and the guide plate, combined with Figure 5 In the disclosed embodiment, each guide plate 24 has a plurality of teeth on the side facing the shore. A guide groove 240 is defined between two adjacent teeth in the guide plate 24. Correspondingly, a shore tooth plate meshing with the rack plate is provided in the groove wall of the U-shaped groove in the shore.

[0082] In this way, during the process of the transfer cart driving into the lifting platform 21, it will cause serious uneven loading on the lifting platform 21, resulting in the tilting of the lifting platform 21 and affecting the driving-in of the transfer cart. At this time, the tipping moment can be offset by the engagement of the guide plate 24 with the shore tooth plate on the dock shore, ensuring the normal driving-in of the transfer cart. Moreover, during the process of the lifting platform 21 being lowered into the water, the engagement between the guide plate 24 and the shore tooth plate can also play a guiding role for the lifting platform 21, preventing the lifting platform 21 from colliding with the dock.

[0083] Optionally, the caisson transfer system further includes a limiting component 4, and the limiting component 4 is used to be connected to the lifting platform 21 to limit the lifting platform 21 on the shore when the transfer cart 11 drives into the lifting platform 21.

[0084] In the above implementation manner, the limiting component 4 is used to connect the lifting platform 21 to the shore, so that the lifting platform 21 will not shake.

[0085] Figure 6 For the structural schematic diagram of the limiting component, combined with Figure 6 , optionally, the limiting component 4 includes a plurality of corresponding pins 41 and a plurality of pin cylinders 42 in one-to-one correspondence.

[0086] One end of the pin cylinder 42 is connected to the corresponding pin 41, and the other end of the pin 41 is used to be connected to the lifting platform 21. The length direction of the pin 41 is perpendicular to the lifting direction of the lifting platform 21. Along the length direction of the pin 41, the two pins 41 are respectively located on the opposite sides of the lifting platform 21.

[0087] In the above implementation manner, the pin 41 is used to be inserted into the lifting platform 21 to limit the lifting platform 21 on the shore. The pin cylinder 42 is used to drive the pin 41 to move, so that the pin 41 can extend into the lifting platform 21.

[0088] To facilitate the insertion of the pin 41 into the lifting platform 21, a plurality of pin holes corresponding to the pins 41 are provided in the lifting platform 21. The axial direction of the pin holes is the same as the length direction of the corresponding pins 41.

[0089] Optionally, the limiting component 4 further includes a limiting seat 43. The limiting seat 43 is connected to the pin cylinder 42. The limiting seat 43 has a guiding hole 430. The pin 41 is located in the guiding hole 430 and is slidably connected to the limiting seat 43. The guiding hole 430 extends along the length direction of the pin 41.

[0090] The limiting seat 43 is used to provide an installation base for the pin cylinder 42 and at the same time guide the movement of the pin 41, so that the pin 41 can move along the extending direction of the guiding hole 430.

[0091] In the disclosed embodiment, the limiting seat 43 includes a limiting plate 431, a plurality of connecting arms 432 and a limiting block 433. The plurality of connecting arms 432 are respectively located between the limiting plate 431 and the limiting block 433, and the two ends of each connecting arm 432 are respectively connected to the limiting plate 431 and the limiting block 433. The plurality of connecting arms 432 are arranged at intervals along the circumference of the limiting plate 431. The guide hole 430 is located in the limiting block 433, and the extension direction of the guide hole 430 is the same as the length direction of the connecting arm 432.

[0092] The latch oil cylinder 42 is located between the plurality of connecting arms 432, and the latch oil cylinder 42 is connected to the limiting plate 431. In this way, the latch 41 can be movably arranged in the limiting seat 43, and can be connected to the latch oil cylinder 42 at the same time.

[0093] In other examples, the structure of the limiting seat 43 may be other structures, such as a box-type structure, a block-type structure, etc.

[0094] The following briefly introduces the working process of the caisson transfer system provided by the embodiment of the present disclosure:

[0095] The cast caisson is lifted up by the transfer trolley 11, and then the transfer trolley 11 is controlled to move in the transfer track 12, so that the transfer trolley 11 can drive the caisson to move. If the transfer trolley 11 initially moves in the transverse track 121, and the platform track 211 is docked with the transverse track 121, the transfer trolley 11 can pass through the buffer track 123 through the break of the transverse track 121 and reach the platform track 211. If the platform track 211 is docked with the longitudinal track 122, since the transfer trolley 11 can only move along the track it is on, at this time, the transfer trolley 11 can be transferred from the transverse track 121 to the longitudinal track 122 by a crane.

[0096] After the transfer trolley 11 transfers the caisson to the platform track 211, the caisson is placed on the support seat 22. The transfer trolley 11 is controlled to separate the caisson from the transfer trolley 11, and then the transfer trolley 11 is controlled to drive away, and the caisson is launched into the water.

[0097] The lifting platform 21 is lowered into the sea water by the winch 231 and the pulley block 232, and the caisson is floated by the buoyancy of the water, and finally transported to the designated location. The lifting platform 21 will engage with the guide plate 24 when it is lowered into the sea water to prevent the lifting platform 21 from tilting.

[0098] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
