Description

Technical Field

[0001] The invention belongs to the technical field of component transportation, and in particular relates to a heavy-duty component transportation device with a bottom and a transportation method. Background Art

[0002] With the development of large-scale deep-water ports and technological progress in the water transport industry, the wharf structure has also made great progress, and the gravity wharf structure has evolved from a block structure to a caisson structure. Caissons are a type of heavy bottomed structure, and their weight has grown from hundreds of tons and thousands of tons to tens of thousands of tons; the transportation methods of caissons include lifting by crane ships, lowering by inclined frame vehicles, rolling onboard semi-submersible barge landing capsules, rolling onboard semi-submersible barge landing trolleys, rolling onboard semi-submersible barge bottom capsules, and rolling onboard floating dock bottom trolleys.

[0003] At present, the industry usually uses the traditional caisson transportation method to transport caissons of more than 5,000 tons to the floating dock. Figure 1 , Figure 2 As shown, a caisson prefabrication yard is built on the shore side of the wharf to be built. A pedestal leading to the water side is provided in the prefabrication yard. A tower crane and other equipment are provided on the outside of the pedestal. A drainage ditch is recessed at the end of the pedestal. A plurality of trolley grooves are opened under the pedestal surface and track beams are arranged therein. The number and position of the trolley grooves and track beams are related to the specifications of the caisson to be transported. First, a caisson forming mold is supported on the pedestal and concrete is poured to prefabricate the caisson. After the caisson is prefabricated, the caisson forming mold is removed, and then the caisson is lifted by a jack to be placed on the trolley. A set of traction devices is connected to the front side of the caisson. The anchor winch or winch on the floating dock pulls the caisson and the trolley along the track beam through the traction device until the caisson is transported to the floating dock. However, the traditional caisson transportation method has the following shortcomings:

[0004] 1) During transportation, the entire weight of the caisson is concentrated on the trolley, which then transfers the caisson load to the track beam, that is, the caisson applies a linear load to the pedestal area. Therefore, this transportation method has high requirements on the bearing capacity of the foundation. In addition, due to the heavy weight of the caisson, the wheels, bushings and other parts of the trolley are easily damaged, and the maintenance cost is high;

[0005] 2) The structure of the pedestal area is relatively complex, resulting in a series of problems such as a long construction period, high construction cost, and high transportation cost for the caisson prefabrication yard. In addition, the constructed caisson prefabrication yard is a large-scale temporary project. Usually, after the construction of the wharf is completed, the prefabrication yard needs to be landfilled and renovated. Therefore, the more complex structure of the pedestal area will increase the cost of wharf construction. Summary of the invention

[0048] The sealing device comprises a rubber tube skirt 31 and a sealing skirt edge 32; the rubber tube skirt 31 is made of a high-strength rubber material, and the sealing skirt edge 32 is made of a high-elasticity wear-resistant latex or silicone material.

[0049] The upper part of the rubber tube skirt 31 is sleeved on the outer peripheral surface of the lower part of the component 10 and is sealed therewith; the lower part of the rubber tube skirt 31 is folded outward and abuts on the top surface of the pedestal 20 outside the bottom of the component 10, but is not fixedly connected to the top surface of the pedestal 20. Specifically, the rubber tube skirt 31 includes a mounting portion 311, a deformation portion 312 and a pressing portion 313; the mounting portion 311 is sleeved on the outer peripheral surface of the lower part of the component 10, and a pressing plate 314 is provided on the outer wall of the mounting portion 311. The bolts pass through the pressing plate 314 and the mounting portion 311 and are connected to the component 10, so that the upper part of the rubber tube skirt 31 is tightly connected to the outer peripheral surface of the lower part of the component 10. The pressing plates 314 can be multiple pieces, which are arranged at intervals around the outer periphery of the mounting portion 311; the pressing portion 313 abuts on the top surface of the pedestal 20 outside the bottom of the component 10, but is not fixedly connected to the top surface of the pedestal 20; the deformation portion 312 is connected between the mounting portion 311 and the pressing portion 313.

[0050] The outer ring of the sealing skirt 32 is sealingly connected to the inner wall of the rubber tube skirt 31 close to the pedestal 20 ; the inner ring of the sealing skirt 32 is wrapped with a weight core shaft 324 and crimped onto the top surface of the pedestal 20 , but is not fixedly connected to the top surface of the pedestal 20 . Specifically, the sealing skirt 32 includes a connecting portion 321 located at the outer circle, a sealing portion 323 located at the inner circle, and a flexible portion 322 connected between the connecting portion 321 and the sealing portion 323; the connecting portion 321 is connected to the inner wall of the deformation portion 312 of the rubber tube skirt 31 close to the pedestal 20; a pressure block is provided on the outer wall of the deformation portion 312 of the rubber tube skirt 31, and the pressure blocks may be multiple blocks, which are arranged at intervals around the outer periphery of the deformation portion 312; a pressure ring is provided outside the connecting portion 321 of the sealing skirt 32, and the bolts are connected to the pressure blocks after passing through the pressure ring and the connecting portion 321, so that the sealing skirt 32 is tightly connected to the rubber tube skirt 31; the sealing portion 323 is pressed on the top surface of the pedestal 20 outside the bottom of the component 10, and a weight core shaft 324 is wrapped in the sealing portion 323, so that the sealing portion 323 is pressed against the top surface of the pedestal 20, but the sealing portion 323 is not fixedly connected to the top surface of the pedestal 20.

[0051] The inflation device includes an inflation main pipe 41 and a plurality of inflation branches 42. The plurality of inflation branches 42 are arranged in parallel and buried in the pedestal 20, and the extension direction of the inflation branch pipes 42 is perpendicular to the movement direction of the component 10; the air inlet end of the inflation branch pipe 42 is bent upward at the edge of the pedestal 20 to extend out of the pedestal 20. In the area of ​​the pedestal 20 that the component 10 can pass through when moving, that is, within the width range of the pedestal 20 corresponding to the span of the component 10, a plurality of inflation ports 21 are opened above each inflation branch pipe 42, and an inflation riser 43 connected one by one with the inflation ports 21 is arranged on each inflation branch pipe 42. The inflation branch pipes 42 and the inflation riser 43 are corrosion-resistant PPE pipes. The air inlet end of the inflation main pipe 41 is connected to an air compressor station 40, and the air outlet end of the inflation main pipe 41 is connected to the air inlet ends of all the inflation branch pipes 42; the inflation branch pipes 42 can be supplied with air through the inflation main pipe 41 by the air compressor station 40; a gate valve 44 is provided at the air inlet end of each inflation branch pipe 42 to individually control the switching state of each inflation branch pipe 42.

[0052] The traction device is connected to the front side of the component 10 in the direction of movement. The traction device generally includes a fixed pulley block, a movable pulley block, a traction rope and a traction beam, etc. Its specific structure and working principle are well known to those skilled in the art and will not be described in detail here. The traction device will be connected to the anchor windlass or winch on the floating dock, and the anchor windlass or winch will provide power for the traction device.

[0053] To further illustrate, when the air compressor station 40 is started, the compressed air generated is inflated toward the bottom of the component 10 through the inflation main pipe 41, the inflation branch pipe 42, the inflation riser 43 and the inflation port 21, and the component 10 can float under the action of the compressed air; at this time, the mounting portion 311 of the rubber tube skirt 31 moves upward with the component 10, driving the deformation portion 312 of the rubber tube skirt 31 to deform, and then dragging the pressing portion 313 of the rubber tube skirt 31 to slide inward along the top surface of the pedestal 20, and at the same time, the connecting portion 321 of the sealing skirt 32 moves upward with the deformation portion 312 of the rubber tube skirt 31, driving the flexible portion 322 of the sealing skirt 32 to deflect upward, and the sealing portion 323 of the sealing skirt 32 is deformed due to the internal deformation. The heavy core shaft 324 is embedded and pressed while still maintaining pressure contact with the top surface of the pedestal 20; the inflation is continued until the component 10 floats and leaves the top surface of the pedestal 20 by a preset distance, thereby forming an air chamber 23 between the bottom surface of the component 10 and the top surface of the pedestal 20, that is, an air cushion layer is formed to support the component 10, and then the traction device is used to pull the component 10 in the air-floating state to move along the movement direction; further, during the air-floating movement of the component 10, the sealing device is driven to move synchronously, and the lower part of the rubber tube skirt 31, that is, the pressing part 313, and the inner circle of the sealing skirt 32, that is, the sealing part 323, are always in a dynamic fitting state with the top surface of the pedestal 20 to achieve dynamic sealing of the air chamber 23.

[0054] The above-mentioned exemplary embodiment provides a new transport device for heavy-duty bottomed components 10, which completely changes and simplifies the structure of the pedestal 20 area. The pedestal 20 is only a flat plate structure, which is highly applicable to components 10 of different specifications. Unlike the traditional caisson transport method, it is not necessary to open a trolley groove in the pedestal 20 area, arrange rail beams, etc., thereby shortening the construction period of the prefabrication site and reducing the construction cost. It is also convenient for the transformation of the prefabrication site after the completion of the wharf construction, thereby reducing the wharf construction cost. In addition, the air cushion layer is used to hold up the component 10, and the top of the pedestal 20 is supported by the air cushion layer. The surface bears a uniformly distributed load. Compared with the situation in which the pedestal 20 bears a linear load in the traditional caisson transportation method, the pedestal 20 of this embodiment bears a surface load, so the load is reduced in stages, and the bearing capacity requirement of the foundation is greatly reduced, thereby reducing the cost of the prefabrication site; in addition, the air cushion layer is used to support the component 10, so that the movement resistance of the component 10 is greatly reduced, so the configuration of the traction device such as the pulley block can be reduced, and the power consumption of the anchor machine or winch on the floating dock can be reduced, thereby reducing equipment investment and achieving energy saving and consumption reduction.

[0055] refer to Figure 4 , Figure 6As shown, in some embodiments, the heavy-duty bottomed component transport device further includes an air supply device, which includes an air compressor and an air supply pipe 45. The air supply pipe 45 is arranged around the outer peripheral side of the rubber tube skirt 31, and a plurality of air supply branches (not shown) are arranged at intervals on the air supply pipe 45. The air supply branches penetrate the rubber tube skirt 31, and the penetration is sealed. The air compressor is placed on the top of the component 10, and the air outlet of the air compressor is connected to the air inlet of the air supply pipe 45. After the component 10 floats under the action of the compressed air below it or / and during the transport of the component 10, the air compressor can be started according to the situation; when the air compressor is started, the compressed air generated enters the air chamber 23 through the air supply pipe 45 and all the air supply branches to replenish the air chamber 23, thereby compensating for the possible air leakage of the sealing device, ensuring the stability of the air chamber 23 below the component 10, and further ensuring that the component 10 is in a stable air floating state during the entire transport process.

[0056] refer to Figure 3-Figure 6 As shown, in some embodiments, the sealing device further comprises a plurality of weight assemblies 33 arranged around the outer peripheral side of the lower part of the component 10, and each weight assemblies 33 comprises a support 331, a connecting rod 332, a pressure beam 333, a pressure rod 334 and a pressure roller 335. The support 331 is connected to the side of the component 10 and is located above the rubber tube skirt 31. The pressure roller 335 is connected to the outer wall of the rubber tube skirt 31 facing away from the pedestal 20; specifically, the pressure roller 335 is connected to the pressure block on the outer wall of the deformation part 312 of the rubber tube skirt 31. One end of the connecting rod 332 is hinged to the support 331, and the other end is hinged to the side of the pressure beam 333 facing the component 10. One end of the pressure rod 334 is hinged to the pressure roller 335, and the other end is hinged to the side of the pressure beam 333 facing the pedestal 20. By providing the weight assembly 33, this exemplary embodiment can ensure that the lower portion of the rubber tube skirt 31, namely the pressing portion 313, always rests against the top surface of the pedestal 20 during the floating and movement of the component 10, thereby preventing the rubber tube skirt 31 from moving upward too much, causing the sealing portion 323 of the sealing skirt 32 to leave the top surface of the pedestal 20 and cause air leakage, thereby ensuring the sealing effect of the rubber tube skirt 31 and the sealing skirt 32 on the air chamber 23, and further ensuring the stability and safety of the movement of the component 10.

[0057] refer to Figure 4-Figure 6As shown, in some embodiments, the pressure rod 334 includes a fixed rod 3341, a sliding sleeve 3342 and a compression spring 3343. One end of the fixed rod 3341 is hinged to the pressure beam 333, and the other end is sleeved with the sliding sleeve 3342; one end of the sliding sleeve 3342 is an open end, which is sleeved outside the fixed rod 3341, and the sliding sleeve 3342 can reciprocate along the length direction of the fixed rod 3341; the end of the sliding sleeve 3342 away from the fixed rod 3341 is a closed end, which is hinged to the pressure roller 335; the compression spring 3343 is installed in the inner cavity of the sliding sleeve 3342, that is, one end of the compression spring 3343 is crimped to the closed end of the sliding sleeve 3342, and the other end is crimped to the end of the fixed rod 3341; the sliding sleeve 3342 can reciprocate along the fixed rod 3341 under the action of the compression spring 3343, thereby making the pressure rod 334 adjustable. This illustrative embodiment ensures that the lower portion of the rubber tube skirt 31 is always tightly attached to the top surface of the pedestal 20 during the floating and movement of the component 10 through the structural setting of the adjustable pressure rod 334, further ensuring the dynamic sealing effect and reliability of the rubber tube skirt 31 and the sealing skirt 32 on the air chamber 23.

[0058] refer to Figure 3 , Figure 8 , Fig. 9 As shown, in some embodiments, the gas inlet 21 on the pedestal 20 is in the shape of a trumpet opening upward to guide the gas to diffuse upward. An inflatable plate 22 is installed at the upper end of the inflatable plate 21, and a honeycomb-shaped inflatable hole is opened on the inflatable plate 22 to prevent slag and debris that may exist on the pedestal 20 from falling into the inflatable riser 43 or the inflatable branch pipe 42 to cause inflatable blockage.

[0059] refer to Figure 7 As shown, in some embodiments, the gate valve 44 at the air inlet end of each inflation branch pipe 42 is a remote-controlled electric gate valve 44, which facilitates the intelligent remote control of the opening or closing of each inflation branch pipe 42.

[0060] refer to Figure 2-Figure 11 As shown, the present invention also provides a method for transporting a heavy-duty component with a bottom, which is performed using the above-mentioned heavy-duty component with a bottom transporting device, and includes a pre-transportation preparation step and a component 10 transporting step.

[0061] Pre-transportation preparation steps include:

[0062] In the pedestal 20, an inflatable branch pipe 42 is pre-buried, an inflatable port 21 is opened, and the inflatable riser 43 on each inflatable branch pipe 42 is connected to the inflatable port 21 one by one; an inflatable plate 22 is installed at each inflatable port 21; the pedestal 20 is usually a concrete casting structure, and it is necessary to ensure that the pedestal 20 has good flatness and cleanliness after forming; the inlet ends of all inflatable branch pipes 42 are connected to the outlet ends of the inflatable main pipe 41; the inlet end of the inflatable main pipe 41 is connected to the air compressor station 40;

[0063] The components 10 are prefabricated on the pedestal 20; specifically, a plurality of component 10 forming molds are erected on the pedestal 20 and concrete is poured using equipment such as a tower crane outside the pedestal 20, so as to prefabricate a plurality of components 10 at the same time, and the component 10 forming molds are removed after the prefabrication is completed; it should be noted that there is a spacing H between the components 10; for the traditional caisson transportation method, the spacing H between the components 10 needs to consider the space requirements for the mold template support, the personnel passage requirements, and the need for the placement of the trolley during transportation, while in this embodiment, due to the use of an air-floating transportation device, the spacing H between the components 10 only needs to consider the template support and the personnel passage requirements, so when the same number of components 10 are prefabricated, the length of the pedestal 20 in this embodiment can be set shorter to reduce the construction cost;

[0064] The sealing device is installed on the component 10; specifically, the upper part of the rubber tube skirt 31, i.e., the installation part 311, is sealedly connected to the outer peripheral surface of the lower part of the component 10, the lower part of the rubber tube skirt 31, i.e., the pressing part 313, is abutted against the top surface of the pedestal 20 outside the bottom of the component 10, and the inner ring of the sealing skirt 32, i.e., the sealing part 323, is pressed against the top surface of the pedestal 20;

[0065] Connect the air supply pipe 45 and the air supply branch pipe to the rubber tube skirt 31; according to the movement order of the components 10, place the air compressor on the top of the component 10 to be moved, and connect the air inlet end of the air supply pipe 45 to the air outlet end of the air compressor;

[0066] The traction device is connected to the front side of the member 10 to be transported in the transport direction.

[0067] The steps of moving the component 10 include:

[0068] Open the gate valves 44 at the air inlet ends of all the air-filling branch pipes 42 corresponding to the air-filling ports 21 below the component to be transported 10, and close the gate valves 44 at the air inlet ends of the other air-filling branch pipes 42;

[0069] The air compressor station 40 is started, and the compressed air generated is continuously inflated toward the bottom of the component 10 to be transported through the air charging main pipe 41, the air charging branch pipe 42, the air charging riser 43 and the air charging port 21, until the component 10 floats and leaves the top surface of the pedestal 20 by a preset distance, so that an air chamber 23 is formed between the bottom surface of the component 10 to be transported and the top surface of the pedestal 20, that is, an air cushion layer is formed to hold up the component 10;

[0070] The component 10 is pulled to move along the moving direction by using a traction device; during the moving process of the component 10, when the inflation port 21 located below the component 10 is about to be exposed outside the air chamber 23, the inlet end gate valve 44 of the inflation branch pipe 42 corresponding to the inflation port 21 is closed; when the inflation port 21 located in front of the moving direction of the component 10 enters the air chamber 23, the inlet end gate valve 44 of the inflation branch pipe 42 corresponding to the inflation port 21 is opened to ensure that the inflation amount in the air chamber 23 makes the component 10 in an air-floating state until the component 10 is moved to a predetermined position;

[0071] After completing the movement of one component 10 , the air compressor and the traction device are installed on the next component 10 to be moved, and the above steps are repeated to move other components 10 in sequence.

[0072] The above-mentioned illustrative embodiment provides a new way of transporting the heavy-duty bottom component 10, so that the heavy-duty bottom component 10 can be transported by air flotation, which greatly reduces the transportation resistance of the component 10, ensures the safety of the transportation of the component 10, and reduces the cost of the pedestal 20 and the construction cost of the prefabrication site, thereby reducing the transportation cost of the heavy-duty bottom component 10.

[0073] refer to Figure 4 , Figure 6 As shown, in some embodiments, the step of moving the component 10 further includes starting the air compressor, and the generated compressed air enters the air chamber 23 through the air supply pipe 45 and the air supply branch pipe to supply air to the air chamber 23; it can be understood that the start time of the air compressor and the air supply pressure can be determined according to the pressure in the air chamber 23. This exemplary embodiment compensates for the possible leakage of the sealing device when the component 10 is moved, ensures the stability of the air chamber 23 under the component 10, and further ensures that the component 10 is in a stable air floating state during the entire movement process.

[0074] refer to Figure 6 As shown, in some embodiments, during the component 10 moving step, the component 10 floats and leaves the top surface of the pedestal 20 by a preset distance of 30 mm to 100 mm, ensuring smooth movement of the component 10 without being affected by the local flatness of the pedestal 20 .

[0075] In summary, the heavy-duty bottom component transporting device and transporting method of the present invention provide a new transporting device and transporting method for heavy-duty bottom components 10 (including but not limited to caissons), solve the shortcomings of the traditional caisson transporting method, greatly simplify the structure of the pedestal 20, and change the load of the pedestal 20 from a linear load to a surface load, thereby reducing the requirements for the bearing capacity of the foundation, thereby reducing the construction period and cost of the prefabrication site; the air cushion layer is used to support the component 10, so that the transportation resistance of the component 10 is greatly reduced, ensuring the safety of the component 10 transportation, and reducing equipment investment and energy consumption, reducing the transportation cost of the heavy-duty bottom component 10, and thereby reducing the cost of dock construction.
