Description

Technical Field

[0001] The invention relates to the technical field of concrete anchorage transportation, and in particular to a method for transporting concrete anchorages with a steel skirt plate at the bottom. Background Art

[0002] Nowadays, the application of floating wind turbines has become a new development trend of offshore wind power. Among them, the prefabrication of skirt-type concrete anchors has become a key link in the construction of deep-sea floating wind power anchor foundations. According to the existing selectivity of concrete prefabrication sites and the particularity of offshore anchor foundation construction, whether it is entrusted to a fixed prefabrication plant for prefabrication or a flexible on-site prefabrication at a self-selected site, it needs to be transported from the prefabrication site to the berth transport ship and then transported to the construction site for foundation construction.

[0003] There are two existing methods for transporting skirt-type concrete anchors. One is to entrust the prefabrication of concrete anchors to a "fixed prefabrication plant". After the prefabrication is completed, the concrete anchor needs to be transported from the prefabrication site across a long urban space distance to the designated dock berth. However, this method greatly increases the risk of anchor transportation due to factors such as long transportation distance and unpredictable emergencies during transportation. The other is to flexibly prefabricate concrete anchors on site in a "self-selected site" method. The prefabrication site is a yard near the dock berth. Although this method solves the problem of transportation distance, the characteristics of skirt-type concrete anchors, such as "large size and heavy weight", are another transportation problem.

[0004] At the same time, the machinery responsible for transporting concrete anchors on site becomes particularly important. Currently, SPMT transport vehicles are used for transporting, but SPMT transport vehicles need to be assembled when in use. However, when assembling existing SPMT transport vehicles, the connectors used are not convenient for quickly connecting and assembling multiple groups of SPMT transport vehicles. Secondly, the connectors used are disconnected during use, which affects the overall transport work. Summary of the invention

[0005] The purpose of the present invention is to provide a method for transporting concrete anchorages with a steel skirt plate at the bottom, so as to solve the following technical problems:

[0006] The SPMT transport vehicle cannot be assembled quickly, and the connectors used cannot protect the assembled SPMT transport vehicle.

[0007] The object of the present invention can be achieved by the following technical solution: A method for transporting concrete anchorage with a steel skirt at the bottom, comprising the following transporting steps:

[0008] Step 1: Assemble multiple groups of SPMT transport vehicles, and use connectors to assemble multiple groups of SPMT transport vehicles;

[0009] Step 2: Then the SPMT transport vehicles move into position. The operators maneuver multiple groups of SPMT transport vehicles to the reserved space below the anchor. During the process, the positioning of the SPMT transport vehicles is closely observed to prevent collision with the Bailey plate bracket and the concrete cushion layer.

[0010] Step 3: The SPMT transporter lifts and transports the anchor. After it is properly positioned, the SPMT transporter is then raised until the anchor is lifted to an appropriate height and can be removed smoothly.

[0011] Step 4: After the SPMT transport vehicle is shipped out, it is adjusted. After the anchor is lifted, the SPMT transport vehicle is driven out of the bracket according to the preset transportation route. During the process, it passes through the turning area and adjusts the position of the SPMT transport vehicle. Then, the anchor is transported to the lifting position of the berth for loading;

[0012] Step 5: After the SPMT transport vehicle adjusts its position in the turning area, it drives to the designated berth, and the crane ship hoists the anchor onto the transport ship and transports it to the construction sea area;

[0013] Step 6: During the period from the shipment of the anchor to its lifting, a crane is organized to remove the Bailey bracket. After the anchor is lifted off the SPMT transport vehicle, the SPMT transport vehicle transports the remaining I-beams on the vehicle body to the designated unloading location, and the crane lifts the I-beams off the SPMT transport vehicle.

[0014] As a further solution of the present invention: the connecting member includes a first splicing plate and a second splicing plate, two first protective plates are fixedly connected to the bottom of the second splicing plate, protective mechanisms are provided on both sides of the two first protective plates, and a first connecting body is fixedly connected to the bottom of the second splicing plate; the protective mechanism includes a mounting block slidably connected to the first protective plate, a limiting block is fixedly connected to the top of the mounting block, a pulling handle is fixedly connected to one side of the mounting block, a plurality of first rotating seats are fixedly connected to one side of the mounting block, a first rotating shaft is rotatably connected between the first rotating seats, both ends of the first rotating shaft are fixedly connected to torsion springs, a blocking block is fixedly connected to the surface of the first rotating shaft, a limiting groove is provided on one side of the first rotating seat, both ends of the blocking block are fixedly connected to limiting rods, and the limiting rods are slidably connected to the limiting grooves.

[0015] As a further solution of the present invention: two second protection plates are fixedly connected to the top of the first splicing plate, both sides of the two second protection plates are fixedly connected with clamping blocks, and the second protection plates are slidably connected to the first protection plates.

[0018] As a further solution of the present invention: surfaces of the first splicing plate and the second splicing plate are both fixedly connected with fixing bolts, and positions of the plurality of fixing bolts are the same.

[0019] Beneficial effects of the present invention:

[0020] 1. First, the prefabrication site of concrete blocks is transferred from a fixed prefabrication plant to a flexible construction site, which shortens the transportation distance after the concrete blocks are prefabricated and improves construction efficiency. Secondly, the shortening of the transportation distance also correspondingly reduces the impact of unexpected situations during transportation and reduces construction risks. The construction method of using SPMT transport vehicles to transport the skirt-type concrete anchors on site not only overcomes the construction technical difficulties, but also reduces the construction cost risks;

[0032] A method for transferring concrete anchorage with a steel skirt plate at the bottom, comprising the following transfer steps:

[0033] Step 1: Assemble multiple groups of SPMT transport vehicles, and use connectors to assemble multiple groups of SPMT transport vehicles;

[0034] Step 2: Then the SPMT transport vehicles move into position. The operators maneuver multiple groups of SPMT transport vehicles to the reserved space below the anchor. During the process, the positioning of the SPMT transport vehicles is closely observed to prevent collision with the Bailey plate bracket and the concrete cushion layer.

[0035] Step 3: The SPMT transporter lifts and transports the anchor. After it is properly positioned, the SPMT transporter is then raised until the anchor is lifted to an appropriate height and can be removed smoothly.

[0036] Step 4: After the SPMT transport vehicle is shipped out, it is adjusted. After the anchor is lifted, the SPMT transport vehicle is driven out of the bracket according to the preset transportation route. During the process, it passes through the turning area and adjusts the position of the SPMT transport vehicle. Then, the anchor is transported to the lifting position of the berth for loading;

[0037] Step 5: After the SPMT transport vehicle adjusts its position in the turning area, it drives to the designated berth, and the crane ship hoists the anchor onto the transport ship and transports it to the construction sea area;

[0038] Step 6: During the period from the shipment of the anchor to its lifting, a crane is organized to remove the Bailey bracket.

[0040] See also Figures 1 to 6 As shown, the present invention is a method for transporting concrete anchorages with a steel skirt plate at the bottom, wherein the connecting member comprises a first splicing plate 1 and a second splicing plate 2, wherein two first protective plates 3 are fixedly connected to the bottom of the second splicing plate 2, and the two first protective plates 3 are symmetrically arranged about the bottom of the second splicing plate 2, and an installation groove is provided inside the first protective plate 3, and the second protective plate 6 is installed through the arranged installation groove, so that the second protective plate 6 and the clamping block 7 are used to protect the entire connection, and protective mechanisms 4 are provided on both sides of the two first protective plates 3, and the protective mechanisms 4 can slide on the top of the first protective plates 3, so as to facilitate the subsequent disassembly of the second protective plates 6 and the clamping block 7, and the bottom of the second splicing plate 2 is fixedly connected to a first connector 5, and the first connector 5 is spherical as a whole;

[0041] The protection mechanism 4 includes a mounting block 401 slidably connected to the first protection plate 3, a limit block 402 is fixedly connected to the top of the mounting block 401, and the protection mechanism 4 as a whole is slidably connected to the first protection plate 3 through the limit block 402, which supports the protection mechanism 4 as a whole on the one hand and limits the protection mechanism 4 on the other hand. A pull handle 403 is fixedly connected to one side of the mounting block 401, and a plurality of first rotating seats 404 are fixedly connected to one side of the mounting block 401, and the first rotating seats 404 are grouped in pairs, and the mounting One side of the block 401 is provided with a plurality of first rotating seats 404, and the first rotating seats 404 are rotatably connected with a first rotating shaft 405, and both ends of the first rotating shaft 405 are fixedly connected with a torsion spring 406, and the torsion spring 406 is used to reset the subsequent rotating blocking block 407, so that the blocking block 407 is used to limit the clamping block 7, so as to ensure the integrity of the connection between the second protection plate 6 and the first protection plate 3, and avoid the situation of separation. The surface of the first rotating shaft 405 is fixedly connected with a blocking block 407, and the blocking block 407 The surface of is horizontally arranged, and the purpose of horizontal arrangement is to facilitate the subsequent extraction from the clamping block 7. A limiting groove 408 is provided on one side of the first rotating seat 404. The limiting groove 408 is a quarter circular groove. The mutual sliding between the limiting groove 408 and the limiting rod 409 is used to limit the rotation range of the blocking block 407, thereby ensuring that the blocking block 407 will not rotate in the opposite direction when pulled. Both ends of the blocking block 407 are fixedly connected to the limiting rod 409, and the limiting rod 409 is slidably connected to the limiting groove 408. 409 is slidably connected to the inside of the limiting groove 408, and the limiting groove 408 limits the limiting rod 409. The first protective plate 3 and the second protective plate 6 cooperate with each other to ensure the overall connection of the first splicing plate 1 and the second splicing plate 2, thereby preventing the first splicing plate 1 and the second splicing plate 2 from falling off during work and causing the overall connection to be disconnected, thereby protecting the entire SPMT transport vehicle assembly. Secondly, the overall structure is simple and the operation is quick, which facilitates the rapid assembly of the SPMT transport vehicle.

[0042] Two second protective plates 6 are fixedly connected to the top of the first splicing plate 1, and both sides of the two second protective plates 6 are fixedly connected with snap-in blocks 7. The second protective plates 6 and the snap-in blocks 7 can be inserted into the inside of the first protective plate 3. The arrangement ensures that the first splicing plate 1 and the second splicing plate 2 will not unilaterally detach when they are connected as a whole, further enhancing the stability of the overall connection, and the second protective plate 6 is slidably connected to the first protective plate 3.

[0043] A threaded sleeve 11 is fixedly connected to the top of the second splicing plate 2, and a threaded rod 8 is connected to the internal thread of the threaded sleeve 11. The threaded rod 8 is connected to the internal thread of the threaded sleeve 11, and the up and down movement of the threaded rod 8 is further realized. The top of the threaded rod 8 is rotatably connected to a support plate 9. Although the threaded rod 8 and the support plate 9 are in a rotatable connection relationship, there is a limit between the threaded rod 8 and the support plate 9, that is, the threaded rod 8 will drive the movement of the support plate 9 during the movement, thereby realizing subsequent work. A second connector 10 is fixedly connected to the top of the support plate 9. The interior of the second connector 10 is hollow, and the size of the second connector 10 matches the size of the first connector 5.

[0044] A plurality of second rotating seats 12 are fixedly connected to the top of the first splicing plate 1, and a second rotating shaft 13 is rotatably connected between the plurality of second rotating seats 12. Two connecting blocks 14 are fixedly connected to the surface of the second rotating shaft 13. Two connecting blocks 14 are symmetrically arranged on the surface of the second rotating shaft 13, and one end of the two connecting blocks 14 is fixedly connected to the support plate 9. The movement of the connecting block 14 drives the movement of the support plate 9, and then drives the overall movement of the second connector 10 to clamp the first connector 5.

[0045] The surfaces of the first splicing plate 1 and the second splicing plate 2 are both fixedly connected with fixing bolts 15 , and the positions of the fixing bolts 15 are the same.

[0046] The working principle of the present invention is as follows: first, the connector of the present application is used to assemble multiple SPMT transport vehicles. First, the first splicing plate 1 and the second splicing plate 2 are fixedly connected to the two ends of the SPMT transport vehicles to be assembled, respectively. Then, the second splicing plate 2 is moved to drive the first connector 5 to connect to the inside of the second connector 10. The first connector 5 will drive the first protection plate 3 and the protection mechanism 4 to move as a whole during the movement, and the second protection plate 6 and the clamping block 7 will be inserted into the inside of the first protection plate 3 during the movement. With the continued movement of the second splicing plate 2 and the first connector 5, the first connector 5 contacts the bottom of the second connector 10. At this time, the threaded rod 8 is rotated inside the threaded sleeve 11, and the support plate 9 and the second connector 10 are driven to move as a whole. The second connector 10 will squeeze one end of the connecting block 14 downward during the movement. The connecting block 14 rotates by being squeezed on the surface of the second rotating shaft 13, and then the other end of the connecting block 14 will drop and limit the first connector 5.

[0047] Then, the first protection plate 3 and the protection mechanism 4 come into contact with the second protection plate 6 and the clamping block 7 along with the movement of the second splicing plate 2. The clamping block 7 will drive the rotation of the blocking block 407 to one side. When the blocking block 407 rotates on the first rotating shaft 405, the limiting rod 409 will rotate along with the blocking block 407. When the clamping block 7 passes through the blocking block 407 on the surface of the mounting block 401, the torsion spring 406 will reset the blocking block 407, thereby limiting and clamping the plug-in clamping block 7. However, due to the action of the limiting groove 408 and the limiting rod 409, the blocking block 407 will be restricted from rotating, thereby limiting the second protection plate 6 and the clamping block 7 as a whole. Similarly, the assembly work between multiple groups of SPMT transport vehicles can be completed, and work can start after the assembly is completed.

[0048] After the overall work is completed, when the SPMT transport vehicle needs to be disassembled, the pulling handles 403 on both sides of the first protective plate 3 are pulled to use the limit blocks 402 to drive the mounting blocks 401 to slide inside the first protective plate 3 to separate the protective mechanism 4 from the first protective plate 3. After the protective mechanism 4 is separated from the first protective plate 3, the second protective plate 6 and the clamping block 7 can be removed from the inside of the first protective plate 3 as a whole. After the separation is completed, the threaded rod 8 can be rotated in the reverse direction to drive the support plate 9 and the second connector 10 to move in the reverse direction, thereby separating the first connector 5 and completing the disassembly work for rectification.

[0049] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
