[0002] With the continuous deepening of human development and utilization of oil and gas resources, the key area of ​​oil and gas exploration and development has shifted from land to ocean. Therefore, drilling engineering operations must also be carried out in the vast ocean. When conducting oil and gas drilling construction at sea, the drilling rig weighing hundreds of tons must have sufficient support and placement space, and there must also be a place for drilling personnel to live. The offshore oil drilling platform has taken on this important task. When using the water drilling platform, a fall-proof guardrail for the water drilling platform is also required.

At this time, the guardrail body 3 can be fixedly installed on the platform body 1, and the staff can effectively install the guardrail body 3 without using welding and bolts, etc., which effectively improves the installation efficiency of the guardrail body 3. When the construction equipment accidentally hits the guardrail body 3, the protective assembly can effectively buffer the impact force generated during the collision, so that the guardrail body 3 can be effectively protected, which not only improves the protection effect and safety factor of the guardrail body 3, but also can provide certain protection for the construction equipment. When the staff needs to adjust the overall height of the guardrail body 3 according to actual needs, it is only necessary to use the extension assembly to conveniently adjust the overall height of the guardrail body 3, so as to further improve the protection effect of the guardrail body 3 on the platform body 1, and at the same time, it can effectively improve the practicality of the guardrail body 3, saving time and effort.

[0035] In order to conveniently fix and install the guardrail body 3 and the platform body 1, the fixing assembly includes fixing plates 5 respectively arranged on both sides of the outer wall of the fixing frame 2, and sliding rods 17 are symmetrically arranged inside the fixing plate 5, and the two ends of the plurality of sliding rods 17 are respectively fixedly connected to the two sides of the inner wall of the fixing plate 5, and a movable plate 18 is arranged inside the fixing plate 5, and a guide groove for the movement of the sliding rod 17 is opened inside the movable plate 18, and the outer sides of the plurality of sliding rods 17 are respectively sleeved with return springs 19, and the plurality of return springs 19 are all in contact between the movable plate 18 and the fixed plate 5, and the opposite sides of the two movable plates 18 are fixedly connected with a plug rod 21, and the contact surfaces of the two fixing plates 5 and the fixing frame 2 are provided with guide grooves for the movement of the plug rod 21, and the outer walls of the connecting plate 8 are provided with guide grooves for the movement of the plug rod 21, and the upper surface of the movable plate 18 is fixedly connected with a pull handle through a fixing block 20, and the upper surface of the fixing plate 5 is provided with a guide groove for the movement of the fixing block 20 When the guardrail body 3 and the platform body 1 need to be fixedly installed, only the handle needs to be pulled first. At this time, the handle will drive the fixed block 20 to move synchronously, and the fixed block 20 will drive the movable plate 18 to move synchronously outside the slide bar 17. During the movement of the movable plate 18, the reset spring 19 will be squeezed, and the movable plate 18 will also drive the plug-in rod 21 to move synchronously. At this time, the connecting plate 8 is plugged into the inside of the fixed frame 2, and then the handle is released. At this time, the reset spring 19 is reset, driving the movable plate 18 to reset and move synchronously, and the movable plate 18 drives the plug-in rod 21 to move synchronously. When the plug-in rod 21 is plugged into the guide grooves on both sides of the outer wall of the connecting plate 8, the connecting plate 8 can be fixed to the fixed frame 2. At this time, the guardrail body 3 and the platform body 1 can be fixedly installed without the use of bolts and welding, etc., which effectively improves the installation efficiency of the guardrail body 3.

[0036] Considering that after the guardrail body 3 and the platform body 1 are fixedly installed, it is necessary to further improve the stability of the installation between the connecting plate 8 and the fixed frame 2, so as to further improve the firmness of the installation between the guardrail body 3 and the platform body 1, a plurality of positioning sleeves 9 are fixedly connected to the upper surface of the fixed frame 2, and a guide groove for the positioning sleeve 9 to move is provided at the bottom of the connecting plate 8. When the connection plate 8 and the fixed frame 2 are fixed, the positioning sleeve 9 will also be synchronously inserted into the guide groove at the bottom of the connecting plate 8. At this time, the positioning sleeve 9 can be used to further improve the stability of the installation between the connecting plate 8 and the fixed frame 2. At the same time, the positioning sleeve 9 can also play a certain auxiliary positioning role, which can further facilitate the staff to install the connecting plate 8 and the fixed frame 2.

During the movement of the slider 25, the buffer spring 26 will be stretched. At this time, the buffer spring 26 can effectively buffer the impact force generated by the collision of the construction equipment, thereby effectively protecting the guardrail body 3 and preventing the guardrail body 3 from falling off after being hit, further improving the service life and protection effect of the guardrail body 3, and at the same time effectively improving the safety factor of the guardrail body 3. Through the setting of the damping rod 16, the elastic potential energy of the buffer spring 26 can be effectively limited, thereby preventing the buffer spring 26 from repeatedly rebounding and affecting the buffering effect of the buffer spring 26.

[0038] In order to effectively extend the service life of components such as the damping rod 16 and the buffer spring 26, an accordion dust cover 7 is fixedly connected to the rear end surface of the guardrail body 3, and the other end of the accordion dust cover 7 is fixedly connected to the outside of the protective plate 4. The accordion dust cover 7 can effectively provide dust-proof protection for components such as the damping rod 16 and the buffer spring 26, thereby effectively extending the service life of components such as the damping rod 16 and the buffer spring 26, and at the same time will not cause any impact on the normal use of components such as the damping rod 16 and the buffer spring 26.
