[0001] This utility model relates to the field of guardrail technology, specifically a guardrail for port terminals. Background Technology

[0002] With the rapid development of the global shipping industry, the safety and efficient operation of port terminals, as important hubs of international trade, have become increasingly critical. In order to ensure the safety of personnel, equipment and cargo, port terminals need to be equipped with effective protective facilities.

[0003] In existing port and wharf guardrail systems, the connections between adjacent guardrails and the bars on them mostly rely on welding. This results in complex and time-consuming installation procedures, requiring specialized welding equipment and technicians on-site, increasing construction difficulty and costs. Furthermore, the welding process can generate fumes and noise, adversely affecting the environment, and overall installation efficiency is low. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a protective railing for port terminals that can be quickly installed and dismantled, thereby improving work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective railing for port terminals includes a chassis and a frame. A limiting block is fixedly installed on one side of the frame, and a limiting hole is formed on the limiting block. A mating groove adapted to the limiting block is formed on the other side of the frame. Sliding blocks are slidably installed on both sides of the frame. A connecting rod is fixedly installed between two sliding blocks. An installation block is fixedly installed on the sliding block located on the side of the mating groove. A limiting rod adapted to the limiting hole is fixedly installed on the installation block. A fixing block is fixedly installed on the frame. An adjustment mechanism is provided inside the fixing block. A rod is movably installed on the frame.

[0007] Preferably, the adjusting mechanism includes a threaded rod, which is rotatably installed inside the fixed block. One end of the threaded rod protrudes from the fixed block and is fixedly mounted with a handwheel. A nut pair is threaded onto the threaded rod, and two fixed rods are fixedly mounted on the nut pair. The fixed rods are fixedly connected to the connecting rod.

[0008] Preferably, the fixing block has a groove for the two fixing rods to slide.

[0009] Preferably, fixing pads are evenly and equidistantly fixed on both the left and right sides inside the frame, and movable pressure blocks are evenly and equidistantly fixed on the inward-facing side of the two sliding blocks.

[0010] Preferably, the fixed pad and the movable pressure block can be joined together to form a rectangle whose inner cross-section corresponds to the cross-section of the rod.

[0011] Preferably, a positioning block is fixedly installed on the movable pressure block, and a positioning groove adapted to the positioning block is opened on the fixed pad at the corresponding position.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model achieves rapid installation and disassembly through modular design and height-adjustable sliding blocks, significantly improving work efficiency. Its robust mechanical locking mechanism (such as the cooperation between the limiting hole and the limiting rod) and multi-point contact design (the fixed pad and the moving pressure block are tightly fitted to the rod body) enhance the safety and stability of the structure, ensuring that it will not loosen or shake when subjected to external forces. Most components are detachable, facilitating maintenance and replacement and reducing long-term operating costs. In addition, the weld-free design simplifies the installation process and avoids stress concentration problems, improving durability. This guardrail not only provides efficient and flexible safety protection but also significantly improves the safety management level and operational efficiency of port terminals.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 7 A protective railing for port terminals includes a base 1 and a frame 2. The base 1 is used to stably fix the entire protective railing to the ground of the terminal by means of expansion bolts, while the frame 2 constitutes the main support structure of the protective railing. The two work together to ensure the overall stability of the protective railing.

[0024] A limiting block 3 is fixedly installed on one side of the frame 2. A limiting hole 4 is provided on the limiting block 3. A docking groove 12 adapted to the limiting block 3 is provided on the other side of the frame 2. The docking groove 12 cooperates with the limiting block 3 to realize modular assembly, which facilitates the quick installation of adjacent guardrails.

[0025] Sliding blocks 5 are slidably installed on both sides of frame 2. A connecting rod 6 is fixedly installed between two sliding blocks 5. An installation block 15 is fixedly installed on the sliding block 5 located on one side of the docking groove 12. A limiting rod 16 adapted to the limiting hole 4 is fixedly installed on the installation block 15. By causing the sliding block 5 to descend, the limiting rod 16 can gradually enter the limiting hole 4 in the limiting block 3, thereby enabling the rapid splicing of adjacent guardrails.

[0026] A fixing block 7 is fixedly installed on the frame 2. An adjustment mechanism is provided inside the fixing block 7. The adjustment mechanism allows the connecting rod 6 and the sliding block 5 to be adjusted in height, which facilitates the installation. A rod 11 is movably installed on the frame 2.

[0027] The adjustment mechanism includes a threaded rod 17, which is rotatably installed inside the fixed block 7. One end of the threaded rod 17 protrudes from the fixed block 7 and is fixedly mounted with a handwheel 8. A nut pair 14 is threadedly installed on the threaded rod 17, and two fixed rods 13 are fixedly installed on the nut pair 14. The fixed rods 13 are fixedly connected to the connecting rod 6.

[0028] When the handwheel 8 is rotated, the threaded rod 17 can be rotated, which in turn allows the nut assembly 14 and the fixing rod 13 to be raised or lowered. This allows the height of the connecting rod 6 and the sliding block 5 to be changed, thus facilitating installation activities.

[0029] The fixing block 7 has a groove for the two fixing rods 13 to slide. The groove provides a guide path for the fixing rods 13, ensuring that they can move smoothly without deviating from the track, thus ensuring a smooth adjustment process.

[0030] Fixed pads 9 are evenly and equidistantly fixed on both the left and right sides inside the frame 2, and movable pressure blocks 10 are evenly and equidistantly fixed on the inward side of the two sliding blocks 5.

[0031] When the sliding block 5 is at a higher height, the fixed pad 9 separates from the corresponding movable pressure block 10, and the rod 11 can be directly inserted. Then, the sliding block 5 is lowered, and the installation of the rod 11 is completed through the cooperation of the fixed pad 9 and the movable pressure block 10.

[0032] The fixed pad 9 and the movable pressure block 10 can be joined together to form a rectangle whose inner cross-section corresponds to the cross-section of the rod 11.

[0033] The fixed pad 9 and the movable pressure block 10 work together to fit tightly against the rod 11 during adjustment, forming a stable clamping force to prevent the rod 11 from shaking or shifting. No welding is required, making it easy to quickly assemble.

[0034] A positioning block 18 is fixedly installed on the movable pressure block 10, and a positioning groove 19 adapted to the positioning block 18 is opened in the corresponding position on the fixed pad 9. The combination of the positioning block 18 and the positioning groove 19 further strengthens the connection between the movable pressure block 10 and the fixed pad 9, making the guardrail more stable and reliable when subjected to external forces.

[0035] The working process of this utility model is as follows: First, the frame 2 and the base 1 are firmly fixed to the dock ground by means of expansion screws, so as to provide a stable support foundation for the entire guardrail.

[0036] By adjusting the sliding block 5 to the highest position, the limiting block 3 is inserted into the docking groove 12 on another guardrail. At this time, the fixed pad 9 is separated from the moving pressure block 10 and can be directly inserted into the rod body 11.

[0037] After installation, the sliding block 5 is lowered by the adjustment mechanism, so that the moving pressure block 10 gradually approaches the fixed pad block 9 until the two are tightly fitted to form a rectangle with an inner cross section that matches the rod body 11, thus clamping and fixing the rod body 11. When the sliding block 5 is lowered to the appropriate position, the limiting rod 16 will be inserted into the limiting hole 4 of the limiting block 3 to prevent it from moving accidentally, while ensuring that the connection between adjacent guardrails is stable and reliable.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
