DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0026] Example 1

[0027] A road construction protection device, such as Figs. 1 to 4 As shown, the device includes a storage shell 4. Slide assemblies are installed on both inner walls of the storage shell 4, and railing assemblies are slidably connected to the slide assemblies. The railing assembly includes a support rod 15 and a slider 17. The slider 17 is slidably connected to the outer wall of the slide assembly, and the support rod 15 is rotatably connected between the two sliders 17. A protective plate 2 is welded to the outer wall of the support rod 15, and a support rod 13 is rotatably connected to the end of the protective plate 2 away from the support rod 15. A protective plate 3 is welded to the outer wall of the support rod 13, and a support rod 1 is welded to the end of the protective plate 3 away from the support rod 13. A moving assembly 1 is installed at the bottom of the support rod 1.

[0028] When road surface protection is required during construction, the initial stage utilizes the storage shell 4 to house the guardrail assembly, thereby reducing the space occupied by the entire device. In use, the guardrail assembly is slid along the slide assembly, allowing it to move out of the storage shell 4. The guardrail assembly can then be enclosed by the protective plates 1 and 2, thus achieving the purpose of road surface protection during construction. In this embodiment, by rotatably connecting the support rod 2 13 and the protective plate 1 2, and rotatably connecting the support rod 3 15 and the slider 17, the overall tilt angle of the protective plates 1 and 2 3 can be adjusted within a certain range. This allows the guardrail assembly to perform construction protection through enclosure, improving the flexibility of protection and ensuring the protective effect.

[0029] The slide assembly includes a slide rod 18 and a pad 19. The pad 19 is welded to the inner wall of one side of the storage shell 4, and the slide rod 18 is welded to the outer wall of one side of the pad 19. The slider 17 and the slide rod 18 are slidably connected.

[0030] The slider 17 can be guided to move along its path when it slides by the slider 17.

[0031] The inner wall of one side of the storage shell 4 is fixed with a limiting plate 16 by screws, and the limiting plate 16 and the slider 17 are used together.

[0032] By setting a limit plate 16, the maximum movement distance of the slider 17 can be limited, preventing the slider 17 from detaching from the slide bar 18.

[0033] The top outer wall of the support rod 13 is welded with a guide plate 14, and the surface of the guide plate 14 is provided with a hole for use with the slide rod 18, and the end of the slide rod 18 away from the pad 19 is tapered.

[0034] When the protective plate one 2 and the protective plate two 3 are stored into the storage shell 4, when the guide plate 14 moves to the end of the slide rod 18, the guide plate 14 is slid along the slide rod 18 away from one end of the base plate 19, since the end is a tapered structure, so that the guide plate 14 is slid into the outer wall of the slide rod 18 by the insertion hole, and the width of the guide plate 14 is smaller than the width of the sliding block 17, so as to ensure that the limiting plate 16 cannot block the guide plate 14, when the guide plate 14 and the sliding block 17 are both slid into the outer wall of the slide rod 18, so as to ensure that the protective plate one 2 and the protective plate two 3 are kept in a straight line after storage.

[0035] The moving assembly comprises a mounting shell 21 and a T-shaped rod 22, the mounting shell 21 is welded to the outer wall of the bottom of the supporting rod one 1, the T-shaped rod 22 is slidably connected to the inner wall of the through hole in the bottom of the mounting shell 21, the spring 20 is clamped between the top of the T-shaped rod 22 and the inner wall of the top of the mounting shell 21, and the universal wheel two 12 is rotatably connected to the bottom of the T-shaped rod 22;

[0036] The universal wheel two 12 can be used to support the bottom of the guardrail assembly, and the elastic force of the spring 20 can ensure that the bottom of the universal wheel two 12 is kept in close contact with the road surface, and the universal wheel two 12 can roll along the surface of the road during the movement of the guardrail assembly.

[0037] The outer wall of both sides of the storage shell 4 is welded with the connecting plate 9, and the universal wheel one 5 is rotatably connected to the bottom of the connecting plate 9;

[0038] The universal wheel one 5 can be used in cooperation with the universal wheel two 12, so that the whole device is convenient to move.

[0039] Working principle: In the initial state, the railing assembly is stored inside the storage shell 4. When road construction protection is needed, the user can slide the railing assembly out of the storage shell 4 along the slide assembly. The sliding of the slider 17 on the slide rod 18 ensures smooth movement of the railing assembly. The guiding effect of the slide assembly and the setting of the limiting plate 16 ensure the stability and safety of the slider 17 during movement, avoiding the risk of the slider 17 falling off the slide rod 18. The rotating connection between the support rod two 13 and the protective plate one 2 and between the support rod three 15 and the slider 17 allows the user to adjust the inclination angle of the protective plate one 2 and the protective plate two 3 within a certain range. This flexibility enables the railing assembly to adapt to different construction environments and protection needs. When the protective plate one 2 and the protective plate two 3 need to be stored back into the storage shell 4, the user can adjust the angle of these rotating connections to smoothly store the protective plate one 2 and the protective plate two 3 in a straight line. The design of the moving assembly makes the entire device easy to move. When the user needs to move the device, the universal wheel two 12 can roll on the road surface to reduce frictional resistance. At the same time, the spring force of the spring 20 ensures that the bottom of the universal wheel two 12 and the road surface remain in close contact, enhancing the stability and safety of the device. The universal wheel one 5 on both sides of the storage shell 4 is used in cooperation with the universal wheel two 12, further improving the mobility of the entire device.

[0040] Embodiment 2

[0041] A road construction protection device is provided to ensure the stability of the guardrail assembly in use, as shown in Figs. 1 to 4 The storage shell 4 is supplemented with a horizontal plate one 8 and a horizontal plate two 10 welded on the outer walls on both sides. The horizontal plate one 8 has a through hole on the surface, and a guide rod 6 is connected to the through hole. The bottom of the guide rod 6 is fixed with a support plate 7 through screws. The top of the support plate 7 is rotatably connected with a threaded rod 11, and the threaded rod 11 is threadedly connected with the horizontal plate two 10.

[0042] When the device is moved to the protection site, the threaded rod 11 is rotated to make the support plate 7 move downward along the vertical direction under the guidance of the guide rod 6. When the support plate 7 is in close contact with the road surface, the storage shell 4 is gradually lifted under the guidance of the guide rod 6 by continuing to rotate the threaded rod 11, until the universal wheel one 5 is disconnected from the road surface. At this time, the universal wheel one 5 is suspended between the road surface, which facilitates the pulling out of the guardrail assembly through the slide assembly, and ensures the stability of the storage shell 4 during construction protection.

[0043] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
