[0002] Port construction refers to the process of building port facilities on the edge of the ocean or waters. The main purpose is to facilitate the import and export of goods and strengthen transportation and trade development. Port construction involves the construction of infrastructure such as port area planning, docks, berths, storage yards, and storage facilities. The scale and facilities of the port will be determined according to the economic development needs of the region and the needs of the shipping market.

[0003] During the construction of a port, it is usually necessary to install safety guardrails to enclose the shore of the construction site to prevent people from accidentally falling into the water from the shore. Traditional port construction safety guardrails are usually fixed fence structures, which are fixed to the ground on the shore by bolts or by pouring stone piers at the bottom. They are removed from the ground after the port construction is completed. Although this type of safety guardrail is strong, it cannot adjust the length according to actual conditions. It is also bulky and inconvenient to install and remove. It will leave traces after removal, which will cause trouble for subsequent recovery work.

[0033] When in use, the moving wheel 4 is moved on the ground to adjust the position of the moving column 1, and the moving column 1 is moved to the position that needs protection, and the limit handle 8 is turned, and the limit handle 8 drives the reinforcing rod 16 to rotate out of the horizontal groove, and then the limit handle 8 is adjusted downward, so that the second limit rod 14 drives the first limit rod 13 to move downward, the spring 17 is stretched, and the first limit rod 13 drives the reinforcing rod 16 to move downward until the reinforcing rod 16 leaves the axial groove, and the limit handle 8 is turned again, so that the limit handle 8 drives the reinforcing rod 16 to rotate to abut against the bottom end surface of the limit tube 5. The limit block 7 is placed on the ground, the moving column 1 is raised, the bottom end of the first limit rod 13 is connected to the limit block 7, and the fixing rod 20 fixes the rotation of the rotating block 19 to prevent the moving wheel 4 from rotating, so that the position of the moving column 1 can be doubly fixed. Install the connecting strip 10 in the connecting groove 11 of the moving column 1, install the connecting member 9 on the connecting strip 10, extend the protective strip 24 out of the protective frame 23, and connect the end of the protective strip 24 away from the protective frame 23 to the side of the connecting member 9 away from the connecting strip 10, thereby completing the connection between the protective member 2 and the moving column 1 at one end of the protective member 2. Next, connect the protective member 2 to the moving column 1 at the other end of the protective member 2 using the same principle, and doubly fix the position of the moving column 1. Then, tighten the fastening rod 25 to fix the length of the protective member 2.

[0034] From the above, a safety guardrail for port construction can be used normally. During use, the position of the guardrail can be adjusted by releasing the double fixation of the moving column 1, and the tightening rod 25 can be loosened to adjust the length of the guard 2. After use, the connection between the guard 2 and the moving column 1, the connection between the guard 2 and the connecting member 9, the connection between the connecting member 9 and the connecting strip 10, the connection between the connecting strip 10 and the connecting groove 11, and the connection between the first limit rod 13 and the limit block 7 can be removed one by one, and the limit handle 8 is rotated to align the reinforcing rod 16 with the bottom position of the axial groove. Under the contraction of the spring 17, the second limit member 12 can enter the axial groove, and then the limit handle 8 is lifted and rotated to move the reinforcing rod 16 to the position where the horizontal groove is away from the axial groove, so as to prevent the first limit rod 13 from falling out of the bottom opening of the limit tube 5.

[0035] In this embodiment, the protection strip 24 can extend and retract from the openings at both ends of the protection frame 23, and the end of the protection strip 24 away from the protection frame 23 is detachably connected to the connector 9. In other embodiments, the protection frame 23 has an opening at only one end, and the protection strip 24 can only extend and retract from the opening at one end of the protection frame 23, and the end of the protection strip 24 away from the protection frame 23 and the end of the protection frame 23 away from the end opening are detachably connected to the connector 9 respectively.
