Description

Technical Field

[0001] This utility model relates to the technical field of road construction, and in particular to a safety barrier for road construction. Background Technology

[0002] During road construction, safety barriers serve as temporary isolation facilities, primarily used to separate construction areas from traffic areas, ensuring the safety of pedestrians and vehicles while providing necessary warnings.

[0003] Traditional safety barriers are mostly fixed in design, lacking flexibility and adaptability. While simple and straightforward, this design struggles to achieve effective layout adjustments when facing complex terrain or irregular construction sites. For example, on curves, slopes, or other special terrain conditions, fixed barriers cannot be flexibly adjusted in angle, resulting in poor isolation at the construction site and potentially affecting traffic flow efficiency and increasing safety hazards. Furthermore, the installation and dismantling of fixed barriers is cumbersome, typically requiring significant manpower and time, increasing construction costs and time burden. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a safety barrier for road construction that is easy to assemble and disassemble and has strong site adaptability.

[0005] This utility model discloses a safety barrier for road construction, comprising:

[0006] The mounting bracket has two connecting slots at one end and a positioning slot at the other end. A connecting mechanism is installed in the positioning slot, which is used to rotate and connect two adjacent mounting brackets.

[0007] The connecting mechanism includes:

[0008] The assembly is installed in the positioning slot of the mounting bracket by screws, and a baffle is provided in the middle of the cavity of the assembly;

[0009] Two springs are symmetrically installed at both ends of the assembly.

[0010] Two locating pins are symmetrically slidably installed at both ends of the cavity of the assembly. The locating pins are connected to the springs on the same side of the baffle. The locating pins are provided with extensions, which are used to limit the sliding range of the locating pins.

[0011] The isolation panel is installed on the mounting bracket;

[0012] The auxiliary mechanism is mounted on the mounting frame and is used to support the mounting frame.

[0013] As a preferred embodiment of this utility model, the mounting bracket has a hollow internal structure, and the positioning pin is rotatably connected to the mounting bracket.

[0014] As a preferred embodiment of this utility model, the end of the locating pin connected to the mounting bracket is provided with a chamfer.

[0015] As a preferred embodiment of this utility model, the auxiliary mechanism includes:

[0016] A support beam is mounted on a mounting frame, and an adapter is rotatably mounted in the middle of the support beam.

[0017] The mounting component is installed on the adapter component via a transmission mechanism, and the mounting component is provided with a connecting shaft.

[0018] The fixed foot has two extension plates, which are rotatably mounted to the connecting shaft. The fixed foot is provided with assembly holes.

[0019] As a preferred embodiment of this utility model, the transmission mechanism includes:

[0020] A support shaft is mounted on the adapter and is perpendicular to the adapter.

[0021] A hollow tube is installed on a support shaft. The hollow tube is slidably installed along the length of the support shaft, and the mounting piece is installed at the end of the hollow tube.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figures 1 to 5 As shown, this embodiment provides a safety barrier for road construction, comprising:

[0036] Mounting bracket 1 is the basic structural frame of the entire safety barrier. It has two connecting slots at one end and a positioning slot at the other end. A connecting mechanism 2 is installed in the positioning slot. The connecting mechanism 2 is used to rotate and connect two adjacent mounting brackets 1, which facilitates angle adjustment and site layout.

[0037] The connecting mechanism 2 includes:

[0038] Assembly 21 is installed in the positioning groove of mounting bracket 1 by screws 22, and a baffle 23 is provided in the middle of the cavity of assembly 21;

[0039] Two springs 24 are symmetrically installed at both ends of the assembly 21 to provide a restoring force;

[0040] Two positioning pins 25 are symmetrically slidably installed at both ends of the through cavity of the assembly 21 for insertion into the connecting slot of the adjacent mounting bracket 1. The positioning pins 25 are connected to the spring 24 on the same side of the baffle 23. An extension 26 is provided on the positioning pins 25. The extension 26 is used to limit the sliding range of the positioning pins 25 and facilitates the driving of the positioning pins 25.

[0041] The isolation panel 3 is installed on the mounting frame 1 and serves as a functional component that actually provides isolation and warning.

[0042] Auxiliary mechanism 4 is installed on mounting frame 1 and is used to support mounting frame 1;

[0043] In this embodiment, the mounting frame 1 serves as the basic frame, and together with the connecting mechanism 2, it enables the rotational connection of adjacent mounting frames 1. This facilitates flexible adjustment of the baffle angle according to the terrain of the construction site, adapting to diverse on-site layout requirements. The cooperation of the assembly component 21, spring 24, and positioning pin 25 in the connecting mechanism 2 allows the positioning pin 25 to be quickly inserted into or disengaged from the connecting slot of the adjacent mounting frame 1, enabling rapid assembly and disassembly of the mounting frame 1. The extension component 26 both limits the sliding of the positioning pin 25 and facilitates operation and drive, improving assembly efficiency. The isolation plate 3 is installed on the mounting frame 1, playing a core role in isolating the construction area from the outside world and warning pedestrians and vehicles. The auxiliary mechanism 4 provides stable support for the mounting frame 1, enhancing the overall wind and collision resistance of the baffle and preventing it from tipping over. This design, through modular assembly and adjustable angle characteristics, adapts to the isolation requirements of different construction scenarios, while being easy to install, structurally stable, and effectively ensuring road construction safety.

[0044] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the mounting bracket 1 has a hollow internal structure, and the positioning pin 25 is rotatably connected to the mounting bracket 1.

[0045] The end of the locating pin 25 that connects to the mounting bracket 1 is chamfered;

[0046] In this embodiment, the hollow structure inside the mounting bracket 1 reduces its own weight and the difficulty of handling and installation, while providing sufficient space for the positioning pin 25 to rotate with the mounting bracket 1. This ensures that the angle of adjacent mounting brackets 1 can be flexibly adjusted after being connected by the positioning pin 25, adapting to the layout requirements of complex terrains such as curves and slopes in road construction. The chamfered design at the connection end of the positioning pin 25 and the mounting bracket 1 reduces the insertion resistance when the positioning pin 25 is inserted into the connection slot of the adjacent mounting bracket 1, making the docking process smoother and avoiding jamming caused by the right angle at the end. Combined with the restoring force of the spring 24, this further improves the convenience of splicing adjacent mounting brackets 1 and enhances the overall assembly efficiency and structural reliability of the safety baffle.

[0047] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the auxiliary mechanism 4 includes:

[0048] A support beam 41 is mounted on a mounting frame 1, and a transition piece 42 is rotatably mounted in the middle of the support beam 41.

[0049] Mounting component 43 is mounted on adapter 42 via transmission mechanism 44, and a connecting shaft 45 is provided on mounting component 43;

[0050] The fixed foot 46 is provided with two extension plates 47, which are rotatably mounted to the connecting shaft 45. The fixed foot 46 is provided with assembly holes.

[0051] In this embodiment, the support beam 41 is installed on the mounting frame 1, serving as a support foundation to ensure the stability of the overall structure. The adapter 42, which is rotatably installed in the middle, allows the mounting component 43 to rotate flexibly with the angle adjustment of the mounting frame 1, adapting to different installation layouts. The mounting component 43 is connected to the adapter 42 through the transmission mechanism 44. With the rotational installation of the extension plate 47 and the connecting shaft 45, the fixing foot 46 is brought into contact with the ground. The assembly holes on the fixing foot 46 facilitate fixing it to the ground with fasteners such as bolts, further enhancing the wind resistance and collision resistance of the mounting frame 1, preventing the safety baffle from tipping over, and effectively improving the safety and reliability of the safety baffle.

[0052] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the transmission mechanism 44 includes:

[0053] A support shaft 44a is mounted on an adapter 42, and the support shaft 44a is perpendicular to the adapter 42.

[0054] Hollow tube 44b is mounted on support shaft 44a. Hollow tube 44b is slidably mounted along the length of support shaft 44a. Mounting part 43 is mounted on the end of hollow tube 44b.

[0055] Stud 44c is installed in the threaded through hole of hollow tube 44b. Stud 44c is used to support and lock the connection position between shaft 44a and hollow tube 44b.

[0056] Multiple grooves are evenly spaced on the support shaft 44a. The grooves are used to increase the friction strength between the stud 44c and the support shaft 44a.

[0057] In this embodiment, the support shaft 44a is vertically mounted on the adapter 42, providing a stable sliding track for the hollow tube 44b. This allows the mounting component 43 and the fixing foot 46 to be flexibly adjusted in height along the length of the support shaft 44a to adapt to the support requirements of different terrains or construction scenarios. The sliding fit between the hollow tube 44b and the support shaft 44a enables stepless adjustment of the overall height of the auxiliary mechanism 4. By screwing the stud 44c into the threaded through hole of the hollow tube 44b and pressing it against the support shaft 44a, the adjusted height position can be quickly locked. The multiple grooves on the support shaft 44a engage with the end of the stud 44c, significantly increasing the friction strength between them and effectively preventing changes in support height caused by loosening of the stud 44c. This ensures that the fixing foot 46 always maintains a stable support state, improves the adaptability and stability of the safety baffle, and guarantees the safety isolation effect of road construction.

[0058] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the bottom two sides of the mounting bracket 1 are rotatably mounted on the positioning component 5, and the positioning component 5 is provided with through holes;

[0059] In this embodiment, the positioning component 5 can rotate around the bottom of the mounting frame 1 to ensure good contact with the ground. The through-hole design makes it easy to fix the positioning component 5 to the ground with fasteners such as anchor bolts, thereby forming a double-sided stable constraint on the bottom of the mounting frame 1. Together with the fixing feet 46 of the auxiliary mechanism 4, it forms a multi-point support system, which greatly improves the overturning resistance of the mounting frame 1, effectively resists strong winds or collision impacts at the construction site, and enhances the safety of road construction isolation.

[0060] As a preferred embodiment of the above technical solution, such as Figures 1 to 2 As shown, the isolation plate 3 and the mounting bracket 1 are installed with bolts, which facilitates the replacement of the isolation plate 3;

[0061] In this embodiment, the bolt connection method makes the disassembly and assembly of the isolation plate 3 simple and efficient. When the isolation plate 3 is worn, aged or the warning pattern fades due to long-term use, the staff can quickly disassemble and replace the new isolation plate 3 without adjusting the entire mounting frame 1, which greatly shortens the maintenance time and cost. At the same time, this design makes it easy to flexibly replace the isolation plate 3 with different warning signs (such as speed limit, detour, construction area, etc.) according to the needs of different construction scenarios, enhance the warning pertinence and practicality of the safety barrier, and ensure effective reminders to pedestrians and vehicles passing by.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
