Description

Technical Field

[0001] The invention relates to the technical field of pile loading technology, and in particular to an automatic pile loading technology. Background Art

[0002] SPMT is a self-propelled modular hydraulic flatbed truck. Generally, large-diameter piles are loaded onto ships by lifting with large lifting equipment. Since large-diameter piles are manufactured in the inner field, they need to be transported to the front of the dock and lifted onto the ship by large lifting equipment. The transportation in the inner field and the lifting at the dock must be implemented separately, which has low work efficiency. In addition, the piles are densely distributed on the deck of the ship. The traditional lifting method of large lifting equipment has a greater risk of collision. In addition, the lifting method requires a lot of time to position the piles on the deck. This loading process is inefficient and labor-intensive. Therefore, a new loading process for large-diameter piles is needed, which combines the in-field transportation of large-diameter piles with the loading at the dock to perform integrated operations to improve loading efficiency and shorten the time of operating ships in port. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic pile loading process, which can solve the problem of low efficiency and high safety risk of general single pile lifting by gantry crane.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: an automatic loading process of pile bodies, the innovation of which is: the specific loading process is as follows: S1: Equipment unloading and splicing: Use a crane to unload the SPMT in the splicing area and splice it according to the vehicle assembly drawings; S2: Positioning and lifting: The SPMT is moved from the splicing area to the monopile storage area and positioned, and then supported and lifted off the ground using a hydraulic suspension system; S3: Monopile transportation: The entire transportation route from the construction site to the dock must be clear of any obstacles; the monopile will be transported to the dock front together with the SPMT; during the transportation process, personnel from the transportation team will be present around the monopile to guide the SPMT operator on the distance between the monopile and the surrounding buildings; communication with the SPMT operator will be carried out by handheld radio or hand gestures; S4: Installation of RoRo equipment: transport the ramp from the yard to the wharf, complete berthing according to the loading sequence, mark the installation position of the ramp on the ship according to the ramp layout diagram, and finally install the ramp on the ship by crane; S5: Single pile loading: Two personnel are required to stand on the side of the gangway to monitor the situation of the gangway and the dock. Ballast water is adjusted to keep the ship stable and the height difference between the ship deck and the dock plane within 3-10cm. SPMT roll-on / roll-off is completed in steps, and the position of the ship is maintained by calibrating the ballast in the tank at each stage. The speed of SPMT during roll-on / roll-off is limited to 0.5 km / h, and the ship ballast must be ensured to keep up with the loading speed. S6: Monopile in place: When the monopile is in the correct position on the deck of the ship, the vehicle deck is lowered by lowering the height of the hydraulic suspension system; ensuring that the tooling built on the monopile is in contact with the deck, the pressure in the hydraulic system will be reduced at a rate of 50 bar at the same time until the deck bears all the load; S7: Disembark and remove the ro-ro equipment: The SPMT adopts a three-point hydraulic suspension support mode. The SPMT lowers its height until there is enough clearance between the tooling on the vehicle deck and the bottom of the monopile. The SPMT is then moved out from under the monopile. Finally, after the SPMT disembarks, a crane is used to remove the gangplank at the dock.

[0005] Furthermore, in S1, a crane is used to install the control module on the SPMT; a corresponding tooling structure is installed at an accurate position of the SPMT using a crane, a functional test is then performed on the SPMT, and finally the SPMT is spliced ​​together through pipe fittings.

[0006] Furthermore, in S2, the tooling will be installed on the SPMT, and the stop block on the transport saddle on the front side of the SPMT will be removed; and obstacles on the SPMT's walking path will be cleared; the SPMT will be positioned to the correct position of the monopile according to the drawings, the height of the SPMT car plate will be lowered, and the stop block on the transport saddle will be installed in place using a manual forklift and fastened with bolts; according to the drawings, wood or plywood will be arranged on the transport saddle in advance; the SPMT computer will be programmed and interconnected data cables will be installed to create an SPMT vehicle group; the SPMT hydraulic support will be set to three-point support mode; after preparation, the SPMT's hydraulic suspension system will slowly pressurize in increments of 50 bar until the construction support on the monopile rises and completely leaves the ground; the support pressure of each hydraulic circuit will be checked to ensure satisfactory load distribution.

[0007] The advantages of the present invention are: 1) In the present invention, the monopile is transferred onto the ship by a self-propelled modular hydraulic flatbed truck, a supporting tooling is installed on the monopile, and the monopile is lifted off the ground by a self-propelled modular hydraulic flatbed truck, and transferred onto the ship from the dock via a gangway. This method reduces the time spent on hoisting the monopile onto the ship and reduces labor intensity. When disembarking, the stop block at the end of the self-propelled modular hydraulic flatbed truck is directly disassembled and hoisted away; then the self-propelled modular hydraulic flatbed truck is moved away from under the monopile. This method greatly improves the loading efficiency and safety of the monopile. BRIEF DESCRIPTION OF THE DRAWINGS
