Description

Technical Field

[0001] The utility model belongs to the technical field of offshore photovoltaic, and particularly relates to a modular storage and transportation tooling for steel pipe piles. Background Art

[0002] During the construction of offshore photovoltaic, it is necessary to stack and transport steel pipe piles. In traditional practices, the steel pipe piles are naturally stacked and a single one is hoisted by binding with a belt / cable. The hoisting time cost of a single steel pipe pile is relatively high, and natural stacking is prone to bumping and damage to the finished steel pipe piles. At present, there is a situation where one end of the steel pipe pile is a thick mouth and the other end is a reduced mouth, which makes stacking and transportation more difficult. Content of the Utility Model

[0003] The purpose of the utility model is to provide a modular storage and transportation tooling for steel pipe piles.

[0004] The utility model is realized by the following measures: A modular storage and transportation tooling for steel pipe piles, characterized in that it includes a thick-mouth support frame, an intermediate support frame and a reduced-mouth support frame provided with a number of placement holes;

[0005] The thick-mouth support frame, the intermediate support frame and the reduced-mouth support frame all include a lower module, a middle module and an upper module connected in a detachable manner;

[0006] On the upper part of the lower module, the upper and lower parts of the middle module, and the lower part of the upper module of the thick-mouth support frame, semi-circular grooves corresponding to the thick mouth of the steel pipe column are provided;

[0007] On the upper part of the lower module, the upper and lower parts of the middle module, and the lower part of the upper module of the reduced-mouth support frame, semi-circular grooves corresponding to the reduced mouth of the steel pipe column are provided;

[0008] On the upper part of the lower module, the upper and lower parts of the middle module, and the lower part of the upper module of the intermediate support frame, semi-circular grooves corresponding to the middle position of the steel pipe column are provided;

[0009] The placement hole is formed by splicing two adjacent semi-circular grooves up and down;

[0010] Lifting lugs are symmetrically arranged on the thick-mouth support frame, the intermediate support frame and the reduced-mouth support frame.

[0011] Furthermore, a protective cage for preventing axial displacement of the steel pipe column is arranged on the outside of the thick-mouth support frame.

[0012] Furthermore, the protective cage includes an arc part concentric with the placement hole and with the notch facing upwards, and a stop bar arranged at the outer end of the arc part. The arc part includes an arc plate and a number of connecting rods fixedly connected with the thick-mouth support frame.

[0013] Further, the lower module, the middle module, and the upper module are connected by plugging or bolt connection. The plug posts and slots for plugging are generally arranged on both sides of the semi-circular groove. For example, plug posts are symmetrically arranged on both sides of the semi-circular groove on the upper end face of the middle module, slots are symmetrically arranged on both sides of the semi-circular groove on the lower end face of the middle module, slots are symmetrically arranged on both sides of the semi-circular groove on the lower end face of the upper module, and plug posts are symmetrically arranged on both sides of the semi-circular groove on the upper end face of the lower module. The plug posts and slots can also adopt the tenon and mortise structure.

[0014] Further, triangular braces are arranged on both sides below the placement holes on the reduced-opening support frame and the middle support frame. The upper end faces of the triangular braces can contact the outer wall of the steel pipe column to provide the overall support effect of the support frame and prevent the module from swinging during vertical lifting.

[0015] Further, a buffer pad is arranged on the inner wall of the placement hole. The buffer pad can be arranged at the lower part of the placement hole. On the one hand, the buffer pad can be used to protect the steel pipe pile, and on the other hand, through the elastic deformation of the buffer pad, it can adapt to other steel pipe piles with a similar outer diameter.

[0016] Both ends of the thick-opening support frame, the middle support frame, and the reduced-opening support frame are provided with fixing frames in a detachable manner, and the fixing frames are fixed on the hull.

[0017] Reinforcing frames are symmetrically arranged at both outer ends of the thick-opening support frame and the reduced-opening support frame, and the reinforcing frames are fixed on the hull.

[0018] The thick-opening support frame, the middle support frame, and the reduced-opening support frame all include two layers of plates that are parallel to each other, and the two layers of plates are fixedly connected by a plurality of inner lining plates. While reducing the weight, the support strength of the support frame is ensured as much as possible.

[0019] The middle module is provided with several layers, generally 2 - 4 layers.

[0020] The fixing frames and the reinforcing frames are generally fixed on the corresponding support frames by long bolts.

[0021] Usage method:

[0022] Place the lower modules of all the support frames, place the bottom steel pipe piles on the lower modules, plug and install the middle modules to ensure that the upper and lower semi-circular grooves are aligned, place the middle-layer steel pipe piles on the middle modules (the number of middle modules depends on the number of layers of the steel pipe columns), and finally install the upper modules and the top steel pipe piles. At this time, all the support frames and the steel pipe piles form an integral body, and the overall lifting of all the steel pipe piles (from the ground to the hull) can be achieved through the lifting equipment.

[0023] After being lifted onto the hull, fixing brackets are fixedly installed at both ends of the thick-mouth support bracket, the middle support bracket, and the reduced-mouth support bracket; the reinforcing brackets are installed at both outer ends of the thick-mouth support bracket and the reduced-mouth support bracket, and the fixing brackets and the reinforcing brackets are fixedly connected to the hull, and welding can be used. In this way, storage and transportation on the hull can be realized. The fixing brackets and the reinforcing brackets are fixed to the hull and form an integral body with each support bracket to ensure the safety and stability of the steel pipe column during navigation.

[0024] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows: The overall transportation of multiple steel pipe piles can be realized, the problem of long single-lifting time can be solved, and the work efficiency can be improved; each support bracket adopts modular detachable connection, which is convenient for disassembly and assembly and flexible in use; the fixing brackets and the reinforcing brackets can realize fixed connection with the hull to ensure stability during ship transportation; a protective cage is provided to avoid axial sliding caused by different weights at both ends.
