In addition to the top beam at the upper end, the utility model does not have a cross bar, which makes the guardrail difficult to climb. At the same time, the distance between the columns is small, making it difficult to pass through. In addition, the height of the columns is high and difficult to climb over, which improves the protection of personal safety and social security.

[0004] Although the above documents improve the protection of personal safety and social security, in some cases, such as emergency evacuation or accident handling, the guardrail cannot be removed quickly to improve the efficiency of responding to emergencies. In response to the above problems, an assembled curved steel structure guardrail that is easy to assemble is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3The utility model provides an embodiment: an assembled arc-shaped steel structure guardrail that is easy to assemble, including a guardrail 15, a bottom plate 14 is fixedly connected to the lower part of the guardrail 15, a support block 5 is fixedly connected to one side of the bottom plate 14, a mounting plate 2 is fixedly connected to the other side of the bottom plate 14, a motor 3 is fixedly connected to the upper part of the mounting plate 2, a screw rod 4 is fixedly connected to the output end of the motor 3, two sliders 6 are threadedly connected to the outer side of the screw rod 4, and the bottoms of the two sliders 6 are rotatably connected to a rotating shaft 7, both sides of the bottom of the bottom plate 14 are fixedly connected to a movable shaft 13, the outer side of the movable shaft 13 is rotatably connected to a sleeve block 12, the bottom of the sleeve block 12 is fixedly connected to a connecting rod 11, the bottom of the connecting rod 11 is rotatably connected to a rotating shaft 2 9, both ends of the rotating shaft 2 9 are rotatably connected to walking wheels 10, a connecting rod 1 8 is rotatably connected between the rotating shaft 7 and the rotating shaft 2 9, and a fixed component 1 is arranged on both the front and rear sides of the guardrail 15.

[0031] Specifically, when the guardrail needs to be transported urgently, we only need to start the motor 3, and the motor 3 will drive the screw 4 to rotate. The rotation of the screw 4 causes the slider 6 on it to slide toward each other. This action further drives the walking wheel 10 to extend from the outside of the bottom plate 14 to a suitable position through the linkage of the connecting rod 1 8 and the rotating shaft 2 9, and the movable shaft 13 and the connecting rod 2 11. In this process, the rotating shaft 1 7 also plays a key role. After completing the above actions, we can turn off the motor 3. At this time, the walking wheel 10 is ready and can easily transport the guardrail. On the contrary, when the guardrail does not need to be transported urgently, we can start the motor 3 again and let the screw 4 rotate in the opposite direction. This time, the slider 6 on the screw 4 will slide relatively, and the walking wheel 10 is lifted to a suitable position inside the bottom plate 14 through the linkage of the rotating shaft 1 7, the connecting rod 1 8 and the rotating shaft 2 9, and the movable shaft 13 and the connecting rod 2 11. After completing this action, we turn off the motor 3 again. At this time, the handling device has returned to its initial state and is waiting for the next use.

[0032] Reference Figure 2 The fixing component 1 includes a shell 106 and a lower clamping block 105. The upper clamping block 104 is slidably connected inside the shell 106. A thin rod 102 is fixedly connected to the middle of the upper clamping block 104. A spring 103 is sleeved on the outer side of the thin rod 102. The lower clamping block 105 and the upper clamping block 104 are meshed and connected.

[0033] Specifically, when multiple guardrails are not needed, the user only needs to pull the handle 101, and this action will drive the thin rod 102 to move. Under the push of the thin rod 102, the upper clamping block 104 will compress the spring 103, so that the upper clamping block 104 and the lower clamping block 105 are separated. In this way, the two guardrails can be easily separated, which is convenient for users to carry. When multiple guardrails are needed, the user only needs to release the handle 101, and the thin rod 102 will reset under the elastic force of the spring 103. At this time, the upper clamping block 104 and the lower clamping block 105 will re-engage together, so that the two guardrails are tightly connected together. This connection method is both firm and stable, and can effectively prevent the guardrails from loosening or falling off during use.

[0034] Reference Figure 1-Figure 3 The outer side of the slider 6 is slidably connected to the inside of the bottom plate 14, the side of the screw rod 4 away from the motor 3 is rotatably connected to the inside of the support block 5, the right end of the lower block 105 is fixedly connected to the left side of the guardrail 15, the outer wall of the shell 106 is fixedly connected to the outside of the guardrail 15, the end of the thin rod 102 away from the upper block 104 is fixedly connected to the handle 101, one end of the spring 103 is fixedly connected to the outside of the upper block 104, and the other end of the spring 103 is fixedly connected to the inside of the shell 106.

[0035] Specifically, the housing 106 prevents the spring 103 from leaving the inner wall, the installation of the handle 101 makes it more convenient to move between the guardrails 15, the support block 5 is positioned to fix the screw rod 4, and the motor 3 is driven. When the motor 3 is started, the connecting rod 18 pulls the rotating shaft 2 9, thereby pulling the walking wheel 10, so as to achieve the lifting and lowering of the walking wheel 10.

[0036] Working principle: When the guardrail needs to be moved urgently, the motor 3 is started to drive the screw rod 4 to rotate, so that the slider 6 on the screw rod 4 slides towards each other, thereby driving the rotating shaft 1 7, the connecting rod 1 8 and the rotating shaft 2 9, and the movable shaft 13 drives the sleeve block 12 and the connecting rod 2 11, so that the walking wheel 10 extends from the outside of the bottom plate 14 to a suitable position, and the motor 3 is turned off. When the guardrail does not need to be moved urgently, the motor 3 is started to drive the screw rod 4 to rotate, so that the slider 6 on the screw rod 4 slides relatively, thereby driving the rotating shaft 1 7, the connecting rod 1 8 and the rotating shaft 2 9, and the movable shaft 13 drives the sleeve block 12 and the connecting rod 11, so that the walking wheel 10 is lifted to the appropriate position inside the bottom plate 14, and then the motor 3 is turned off. When multiple guardrails are not needed, the handle 101 is pulled to drive the thin rod 102, so that the upper clamping block 104 compresses the spring 103, thereby disengaging the upper clamping block 104 from the lower clamping block 105, and then separating the two guardrails. When multiple guardrails are needed, the handle 101 is released, and the thin rod 102 is driven to reset the spring 103, so that the upper clamping block 104 is engaged with the lower clamping block 105, and then the two guardrails are tightly connected together.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
