Description

Technical Field

[0001] The utility model relates to the technical field of pipe frame transportation, in particular to a multi-purpose cushion device for horizontal roll-on / roll-off transportation of pipe frames. Background Art

[0002] Since the non-slideway horizontal construction of the jacket and the SPMT loading method have the advantages of not occupying slideway resources, not requiring sliding and hauling equipment, less prefabrication of assembly piers, and reusable lifting beams, it can greatly reduce project costs and greatly improve the competitiveness of the construction site. Therefore, in recent years, small jackets of 5000T and below are mostly built in this way. Jackets built in this way are generally arranged with several load-sharing lifting beams for transportation in advance before assembly, and assembly piers are placed under the lifting beams. When transporting the jacket, the jacket and the load-sharing lifting beams are lifted on the top of the SPMT module car, and the assembly piers are removed. At this time, the loading piers are placed on the barge deck in advance. When the SPMT transports the jacket to the designated position on the barge deck, the car body is lowered to make the lifting beam contact with the loading pier, and then the car body continues to be lowered until the car plate and the lifting beam are separated, thereby completing the loading process.

[0003] This method requires the prefabrication of two sets of tooling equipment, namely, assembly piers and loading piers, which will increase the construction cost of the project. In addition, since the jacket is a double-tilted structure, in order to ensure that the assembly piers do not affect the transportation path, the assembly piers need to be removed in time after being cut off, which increases the complexity of the construction. In order to ensure that the loading piers on the barge deck do not affect the transportation path, the piers can only be arranged on both sides of the transportation path, which in turn increases the requirements for the width of the barge and the prefabricated length of the lifting beam. At the same time, when lowering the car body, it is necessary to ensure that the lifting beam is ready to fall on the loading pier, which increases the difficulty of construction and has an adverse impact on the project. For this reason, we propose a multi-purpose pier device for horizontal roll-on / roll-off transportation of jackets. Utility Model Content

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a multi-purpose cushion device for horizontal roll-on / roll-off transportation of a conductor frame.

[0029] According to the attached Figure 1-5, comprising a catheter frame 8 and a lifting beam structure 7 fixedly connected to the bottom of the catheter frame 8, a cushion mechanism is arranged below the lifting beam structure 7, and the cushion mechanism comprises: a support assembly 3, the support assembly 3 is connected to the bottom of the lifting beam structure 7, and the support assembly 3 is used to support the catheter frame 8; a base assembly 2, the base assembly 2 is connected to the bottom of the support assembly 3, and the base assembly 2 is used to support the support assembly 3, a first connecting assembly 4 is arranged between the base assembly 2 and the support assembly 3, and the first connecting assembly 4 is used to connect the base assembly 2 and the support assembly 3; a box assembly 1, the box assembly 1 is fixedly connected to the bottom end of the base assembly 2, and the box assembly 1 is used to support the base assembly 2; the cushion mechanism is formed by welding the box assembly 1 to the base assembly 2, and then connecting the base assembly 2 to the support assembly 3 through the first connecting assembly 4, thereby playing a cushion support role for the catheter frame 8.

[0030] It should be further explained that the box assembly 1 includes an upper flange plate 101 fixedly connected to the end face of the base assembly 2, a lower flange plate 102 located below the upper flange plate 101, a plurality of central longitudinal webs 103 fixedly connected between the upper flange plate 101 and the lower flange plate 102, and a plurality of central transverse webs 104 fixedly connected between the sides of the upper flange plate 101 and the lower flange plate 102 close to each other and fixedly connected between adjacent central longitudinal webs 103; the length, width, height of the box assembly 1 and the arrangement density of the internal central longitudinal webs 103 and the central transverse webs 104 are determined based on the arrangement quantity and position of the pier device, the ground pressure of the conductor frame 8 and the bearing capacity of the ground or barge deck.

[0031] Furthermore, the base assembly 2 is welded to the center position of the box assembly 1, and the base assembly 2 includes an annular mounting seat 201 welded to the top of the box assembly 1 and a plurality of lateral reinforcing ribs 202 welded to the outer surface of the annular mounting seat 201; the plurality of lateral reinforcing ribs 202 are distributed in a circular array with the center of the annular mounting seat 201 as the array center, and one side of each lateral reinforcing rib 202 is welded to the outer surface of the annular mounting seat 201, and the other side of each lateral reinforcing rib 202 is welded to the outer surface of the box assembly 1; by providing the lateral reinforcing ribs 202, the connection between the annular mounting seat 201 and the upper flange plate 101 on the box assembly 1 is made more stable, avoiding easy skewing or even breakage.

[0032] Furthermore, the support assembly 3 includes a support tube 301 and a central reinforcing rib plate 302 fixedly connected to the inside of the support tube 301, and the cross-sectional profile of the central reinforcing rib plate 302 is set to a "M" shape or a "X" shape; by setting the central reinforcing rib plate 302, the structure of the entire support tube 301 is made more stable, avoiding bending or even breakage, and the length of the support tube 301 can be customized according to actual needs, such as one meter, one and a half meters, two meters and other lengths.

[0033] It should be noted that the first connecting component 4 includes a first connecting flange 402 fixedly connected to the end face of the supporting component 3 close to the box component 1 and a first connecting blind flange 401 fixedly connected to the end face of the base component 2 close to the supporting component 3, and the first connecting blind flange 401 and the first connecting flange 402 are connected by multiple groups of first connecting bolts; by fixing the first connecting flange 402 to the supporting tube 301, the first connecting blind flange 401 is fixedly connected to the annular mounting seat 201, and then the first connecting flange 402 is connected to the first connecting blind flange 401 by using the first connecting bolts, it is convenient for initial assembly and subsequent disassembly.

[0034] Furthermore, a connecting pipe 6 is arranged between the supporting assembly 3 and the lifting beam structure 7, and a second connecting assembly 5 is arranged between the connecting pipe 6 and the supporting assembly 3.

[0035] Furthermore, the overall outline of the box assembly 1 is set to be a rectangle, and the outer end surface of the upper flange plate 101, the outer end surface of the lower flange plate 102, the outer end surface of each central longitudinal web 103 and the outer end surface of each central transverse web 104 are all flush with the outer end surface of the upper flange plate 101 or the outer end surface of the lower flange plate 102.

[0036] First, the size and layout position of the cushion device are calculated based on the weight information, structural form, layout of the transport bearing lifting beam structure 7, and the bearing capacity of the barge deck of the conductor frame 8. After the cushion device is prefabricated, the cushions are placed according to the layout position. Further, according to the height of the conductor leg from the ground when the conductor frame 8 is built on land, the height of the support pipe 301 is determined, and the support pipe 301 is connected and fixed to the annular mounting seat 201 through the first connecting component 4. Further, the conductor frame 8 transport lifting beam structure 7 is installed, and then the conductor frame 8 is assembled step by step on the top until the construction is completed. At this time, the cushion device plays the role of the assembly cushion.

[0037] After the construction of the jacket 8 is completed and before it is shipped, the SPMT module vehicle and the transport load-sharing tooling are moved to a specific position and then the SPMT lifts the vehicle body. At this time, the transport lifting beam structure 7 and the jacket 8 with the cushion device are synchronously lifted off the ground, and the SPMT is transported along the transport path. Since the device is synchronously lifted and transported with the jacket 8, there is no need for cutting operations and the transport path will not be interfered with.

[0038] After the jacket 8 is transported to the designated position above the barge, the vehicle body is lowered, and the pier device directly contacts the barge deck and supports the weight of the entire jacket 8. Then the SPMT is evacuated, and the pier device now serves as a loading pier. Also, because the pier device is loaded onto the ship together with the jacket 8, there is no need to place the loading pier on the ship in advance, and the loading pier can be placed on both sides of the jacket 8 without worrying about affecting the vehicle entry path, resulting in an increase in the length of the transport load beam and the barge width requirement, which in turn leads to an increase in project costs.
