[0001] The utility model relates to the technical field of bridge construction, and specifically relates to a folding road closure device for bridge construction. Background Art
[0002] During the bridge construction process, in order to ensure construction safety and progress, it is usually necessary to close the roads in the construction area. Existing road closure devices have problems of inconvenient folding, storage and transportation.
[0003] Chinese Patent (CN220847249U) discloses a folding road closure structure for bridge construction, which involves the coordinated work of multiple components. The structure includes a first support rod and a second support rod. The first support rod is connected to the second support rod through a sliding connection within a fixed ring. A rotating ring is provided within the fixed ring, and a clamping rod is fixed on the rotating ring. These clamping rods can be clamped with the clamping grooves on the first support rod to fix the position of the support rod. When it is necessary to store the road closure structure, rotate the rotating ring so that the clamping rods are disengaged from the clamping grooves, and the first support rod contracts inward under the action of gravity to achieve the folding of the structure. The interception rope is connected to the support rod through a fixing component to form a closed area. The counterweight block at the bottom end of the second support rod increases the stability of the structure and ensures stable placement during use.
[0004] However, the connection method with the counterweight base is not disclosed in the comparative document, which may cause trouble in storage and the disassembly and assembly process is relatively complex. Summary of the Utility Model
[0005] In view of the above problems, a folding road closure device for bridge construction is provided, which includes an interception strip for blocking people. The interception strip is arranged within the first upright post and can be stretched to the second upright post to achieve the purpose of blocking people. The first upright post and the second upright post are arranged within the counterweight base, and the counterweight base is used to stabilize the first upright post and the second upright post. Folding components are provided on the first upright post and the second upright post. The first upright post and the second upright post are each divided into an upper upright post and a lower upright post. The upper upright post and the lower upright post are hinged, and after hinging, the upper upright post and the lower upright post are rotatably connected. Folding clamping seats are provided on the upper upright post and the lower upright post. When the upper upright post and the lower upright post are in a coaxial position after being folded by the folding components, the folding clamping seats on the upper upright post and the lower upright post are also in a coaxial position. At this time, insert pins simultaneously through the folding clamping seats on the upper upright post and the lower upright post to fix the upper and lower upright posts. When storage is required, fold the first upright post and the second upright post through the folding components, and then insert and fix the folded first upright post and the second upright post through the plugging components for easy storage.
[0006] Preferably, the plugging component includes a fixed base on the first upright post and a fixed block on the second upright post. The fixed block and the fixed base are designed for plugging connection.
[0007] Preferably, the lower columns of the first column and the second column are provided with rotating bases, and the counterweight base is provided with insertion slots for the rotating bases to be inserted. After the rotating bases enter the counterweight base through the insertion slots, they rotate in the rotating slots in the counterweight base. Rotate the rotating base in the rotating slot so that the rotating base is misaligned with the insertion slot. Through the misalignment of the rotating base and the insertion slot, it is ensured that the first column and the second column will not be accidentally pulled out.
[0008] Preferably, an intercepting strip mounting seat is provided on the upper column of the first column, and the intercepting strip is pulled out through an intercepting strip outlet provided on the upper column of the first column. The upper column of the second column is provided with an intercepting strip clamping seat for fixing the intercepting strip pulled out from the intercepting strip outlet of the upper column of the first column.
[0009] Preferably, intercepting strip clamping posts for easy taking are provided on the intercepting strip. In the non-construction state, the intercepting strip clamping posts are blocked outside the first column by the intercepting strip outlet. During construction, the intercepting strip clamping posts are clamped and fixed with the intercepting strip clamping seat.
[0010] Preferably, the intercepting strip is coated with a reflective coating for ensuring the visibility of the intercepting strip.
[0011] The beneficial effects of the present utility model compared with the prior art are as follows:
[0012] 1. Through modular design, the present utility model realizes rapid deployment and convenient storage, effectively solving the problems of large volume, difficult to move and difficult to store brought by traditional road closure methods.

Detailed implementation manners
[0026] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners.
[0027] Refer to Figures 1 - 10: A foldable road closure device for bridge construction, including an interception bar 6 for blocking personnel. The interception bar 6 is arranged inside the first upright column 4 and can be stretched to the second upright column 5 to achieve the purpose of blocking personnel. The first upright column 4 and the second upright column 5 are arranged in a counterweight base 3, and the counterweight base 3 is used to stabilize the first upright column 4 and the second upright column 5. A folding assembly 1 is arranged on the first upright column 4 and the second upright column 5. Both the first upright column 4 and the second upright column 5 are divided into an upper upright column 11 and a lower upright column 12. The upper upright column 11 and the lower upright column 12 are hinged, and after hinging, the upper upright column 11 and the lower upright column 12 are rotatably connected. Folding card seats 13 are arranged on the upper upright column 11 and the lower upright column 12. When the upper upright column 11 and the lower upright column 12 are in a coaxial position after being folded by the folding assembly 1, the folding card seats 13 on the upper upright column 11 and the lower upright column 12 are also in a coaxial position. At this time, a pin 14 is inserted through the folding card seats 13 on the upper upright column 11 and the lower upright column 12 at the same time to fix the upper and lower upright columns 12. When storage is required, the first upright column 4 and the second upright column 5 are folded by the folding assembly 1, and then the folded first upright column 4 and the second upright column 5 are plugged and fixed by a plugging assembly 2 for easy storage.
[0028] The utility model aims to solve the problems of large volume, difficult movement and hard storage brought by traditional road closure methods. Through modular design, it realizes rapid deployment and convenient storage. At the same time, it is equipped with an interception bar 6 and a stable counterweight base 3 to ensure the safety and closure effect of the construction area, providing a more flexible, efficient and safe road closure solution for bridge construction. During the bridge construction process, in order to ensure safety, a road closure device is needed. The device in the utility model consists of core components such as an interception bar 6, a first upright column 4, a second upright column 5 and a counterweight base 3. When road closure is required, first, the interception bar 6 is stretched from inside the first upright column 4 to the second upright column 5 to form an effective block to ensure that personnel cannot pass. The first upright column 4 and the second upright column 5 are firmly set on the counterweight base 3, enhancing the overall stability of the device. Both of these upright columns are composed of an upper upright column 11 and a lower upright column 12, and they are rotatably connected through a hinged manner. This design allows the upright columns to be flexibly folded and deployed. When the device needs to be deployed for use, the upper upright column 11 and the lower upright column 12 are in an extended state. Through the fixing effect of the folding assembly 1, they remain upright. At this time, the folding card seats 13 on the upper upright column 11 and the lower upright column 12 are in a coaxial position, and a pin 14 can be inserted to further fix to ensure the stability of the upright columns. When the project is completed and the device needs to be stored, the folding assembly 1 starts to play a role. Next, the plugging assembly 2 is used to plug and fix the folded first upright column 4 and the second upright column 5, thus forming a compact storage state for easy transportation and storage. The entire working process is simple and efficient, not only ensuring the stability and safety of the road closure device during use, but also facilitating the storage work after construction, and it is an indispensable safety device in bridge construction.
[0029] Refer to Figures 1 - 9 : The plug-in component 2 includes a fixed base 22 located on the first upright column 4 and a fixed block 21 located on the second upright column 5. The fixed block 21 and the fixed base 22 are designed for plug-in connection.
[0030] First of all, the plug-in component 2 is composed of a fixed base 22 located on the first upright column 4 and a fixed block 21 located on the second upright column 5. These two components are designed as a plug-in structure, which means they can be nested and locked with each other to fix the position of the upright columns. When the folding road closure device needs to be stored, the first upright column 4 and the second upright column 5 will be folded as designed. During this process, the positions of the fixed base 22 and the fixed block 21 will approach each other relatively, preparing for the plug-in operation. Once the upright columns are folded to the appropriate position, the fixed block 21 can be inserted into the fixed base 22. Due to the plug-in design, a tight connection will be formed between the fixed block 21 and the fixed base 22, thus ensuring that the upright columns will not move or loosen randomly in the stored state. This plug-in design not only simplifies the storage process but also improves the stability and safety of the device. Through the plug-in connection of the fixed block 21 and the fixed base 22, it can be ensured that the folded upright columns remain neat and compact, facilitating transportation and storage.
[0031] Refer to Figures 1 - 10 : The lower upright columns 12 of the first upright column 4 and the second upright column 5 are provided with rotating bases 7. The counterweight base 3 is provided with an insertion slot 31 for the rotating base 7 to be inserted. After the rotating base 7 enters the counterweight base 3 through the insertion slot 31, it rotates in the rotating slot 32 in the counterweight base 3. Rotate the rotating base 7 in the rotating slot 32 so that the rotating base 7 is misaligned with the insertion slot 31. Through the misalignment of the rotating base 7 and the insertion slot 31, it is ensured that the first upright column 4 and the second upright column 5 will not be accidentally pulled out.
[0032] This folding road closure device is specially designed with a unique locking mechanism, that is, rotating bases 7 are provided at the lower parts of its first upright column 4 and second upright column 5. These rotating bases 7 can be firmly inserted into the insertion slots 31 of the counterweight base 3. During the bridge construction process, the alignment of the rotating base 7 and the insertion slot 31 ensures the stability of the upright columns, effectively preventing the upright columns from being pulled out due to external forces or vibrations. This design not only improves the safety of the construction but also ensures the effectiveness of the road closure device during the project.
[0033] Refer to Figures 3 - 10:On the upper column 11 of the first column 4, there is an installation seat 41 for the interception bar 6. The interception bar 6 is pulled out through the output port 42 of the interception bar 6 provided on the upper column 11 of the first column 4. On the upper column 11 of the second column 5, there is a clamping seat 51 for the interception bar 6, and the clamping seat 51 for the interception bar 6 is used to fix the interception bar 6 pulled out from the output port 42 of the interception bar 6 on the upper column 11 of the first column 4.
[0034] On the upper column 11 of the first column 4, there is a design for the installation seat 41 of the interception bar 6, which is specifically set for installing the interception bar 6. When it is necessary to arrange the road closure device, the interception bar 6 is pulled out through the output port 42 of the interception bar 6 provided on the upper column 11 of the first column 4. The function of this output port is to enable the interception bar 6 to smoothly extend from the first column 4 when needed, forming an effective road closure barrier. Then, when the interception bar 6 is pulled out and reaches the appropriate length or position, it will be fixed by the clamping seat 51 of the interception bar 6 on the upper column 11 of the second column 5. The design of the clamping seat 51 of the interception bar 6 ensures that the interception bar 6 can remain stable during the road closure process and will not shift or fall off due to external factors.
[0035] Refer to Figures 1 - 4 :On the interception bar 6, there are clamping posts 6 of the interception bar that are convenient for taking. In the non-construction state, the clamping posts 6 of the interception bar are blocked outside the first column 4 by the output port 42 of the interception bar 6. During construction, the clamping posts 6 of the interception bar are clamped and fixed with the clamping seat 51 of the interception bar 6.
[0036] On the interception bar 6, there are specially designed clamping posts 6 of the interception bar that are convenient for taking. In the non-construction state, the clamping posts 6 of the interception bar are cleverly designed at the position of the output port 42 of the interception bar 6 and are blocked outside the first column 4 by it. Such a design enables the interception bar 6 to remain neat when not in use, will not move or scatter randomly, and is also convenient for construction workers to quickly find and operate. When entering the construction state, the construction workers can easily pull out the interception bar 6 from the output port 42 of the interception bar 6 and make the clamping posts 6 of the interception bar on it be clamped and fixed with the clamping seat 51 of the interception bar 6 on the second column 5. This clamping method not only ensures the stability and safety of the interception bar 6 during the road closure process but also facilitates the construction workers to carry out quick installation and disassembly. Through such a design, the interception bar 6 can remain neat and safe in the non-construction state, and can be quickly fixed and put into use in the construction state, greatly improving the use efficiency and safety of the road closure device.
[0037] Refer to Figure 1 :The interception bar 6 is coated with reflective paint, and the reflective paint is used to ensure the visibility of the interception bar 6.
[0038] The reflective paint makes the interception bar 6 more visible, avoiding the situation that vehicles passing by the construction site at night cannot see the existence of the interception bar 6.
[0039] The above embodiments only represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
