Description

Technical Field

[0001] This utility model relates to the field of road construction protection technology, and in particular to a foldable highway foundation pit rapid protection barrier device. Background Technology

[0002] In highway and municipal engineering projects, foundation pit excavation is a common operation. In order to ensure the safety of construction workers, isolate dangerous areas and guide traffic, protective fences must be set up around the foundation pit.

[0003] Currently, the guardrails commonly used at construction sites are mostly fixed metal guardrails or simple color steel fences. Since foundation pit construction is usually an open-air operation, the stability of the guardrails is easily affected by environmental factors, especially wind. Traditional fixed guardrails have a fixed support base area and are usually designed only for normal weather conditions. When encountering severe weather such as strong winds and gusts, their limited support area and fixed structure cannot provide sufficient anti-overturning moment, causing the guardrails to be easily blown down by the wind.

[0004] In some existing technologies, most guardrails lack a structure that can automatically adjust their stability according to the specific external construction environment. This may result in them being only suitable for specific external environments. When encountering strong winds, the guardrails are prone to tilting, which may pose safety hazards in actual use. In addition, most guardrails are fixed metal frames and lack a structure that is easy to disassemble and fold, making it inconvenient to transport and disassemble them. Utility Model Content

[0005] The main purpose of this utility model is to provide a foldable highway foundation pit rapid protection barrier device, which can effectively solve the problems mentioned above. Most existing protection barriers lack a structure that can be adjusted to adjust their stability according to the specific external construction environment, which may result in them being only suitable for specific external environments. When encountering strong winds, the barriers are prone to tilting, which may pose safety hazards in actual use. In addition, most of the protection barriers are fixed metal guardrail frames, lacking a structure that is easy to disassemble and fold, which makes it inconvenient to transport and disassemble them.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A foldable highway pit rapid protection device includes an installation component one, two of which are symmetrically arranged on the left and right. An installation component two is installed on the top of each of the two installation components one. A connecting mechanism is installed on opposite sides of the outer surfaces of the installation components one and two located on the same side. Anti-tipping mechanisms are symmetrically installed on the lower sides of the opposite surfaces of the two installation components one. A scissor-type telescopic guardrail one is installed on the opposite sides of the two installation components one, and a scissor-type telescopic guardrail two is installed on the opposite sides of the two installation components two. Warning mechanisms are provided on opposite sides of the rear ends of both the scissor-type telescopic guardrail one and the scissor-type telescopic guardrail two.

[0008] Preferably, both of the mounting components have a raised base block installed at their bottom.

[0009] Preferably, both connecting mechanisms include two threaded sleeve seats, the two connecting mechanisms are arranged symmetrically from left to right, and the two threaded sleeve seats on the same side are arranged symmetrically from top to bottom.

[0010] Preferably, the two threaded sleeve seats located on the same side are respectively mounted on opposite sides of the outer surfaces of mounting assembly one and mounting assembly two on the same side.

[0011] Preferably, the inner surfaces of the two threaded sleeve seats are jointly fitted with fixing bolts.

[0012] Preferably, each of the two warning mechanisms includes two power supply devices, which are respectively installed at the rear end of two mounting components one or two mounting components two. Each of the power supply devices has a light panel installed at its rear end, and the two light panels located at the same end have elastic reflective light strips symmetrically installed on their opposite sides.

[0013] Preferably, both anti-tipping mechanisms include a dual-drive motor housing. The two dual-drive motor housings are respectively installed on the lower side of an opposite face of two mounting components. Threaded rods are symmetrically installed on the outer surface of the dual-drive motor housing. Support bearing seats are provided on opposite sides of the outer surfaces of the two threaded rods. Movable seats are provided in the middle and rear parts of the outer surfaces of the two threaded rods. Limit bearing seats are installed on opposite sides of the outer surfaces of the two threaded rods.

[0014] Preferably, a triangular limiting block is installed on the side of each of the movable seats away from the mounting component on the same side. The two triangular limiting blocks on the same side are symmetrically arranged front and back. The bottoms of the two limiting bearing supports on the same side are respectively installed on the opposite sides of the outer surfaces of the two supporting bearing supports on the same side.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device, through its designed warning mechanism, addresses the issue of insufficient light during nighttime construction, a major factor significantly increasing construction safety risks. The warning mechanism effectively compensates for insufficient light by providing light warnings, helping pedestrians and vehicles to promptly identify the construction area and reducing the occurrence of accidents.

[0017] 2. This device features an anti-tipping mechanism that can be adjusted as needed. When the wind is strong, the distance between the two triangular limit blocks at the same location can be extended, thereby significantly increasing the support area and stability of the bottom of the guardrail, effectively resisting the influence of wind and preventing the guardrail from tipping over due to wind. When the wind is weak or space is limited, the distance can be flexibly reduced. This adjustability allows the device to adapt to various construction environments. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1As shown, a foldable highway pit rapid protection device includes an installation component 1. Two installation components 1 are symmetrically arranged on the left and right sides. An installation component 2 3 is provided on the top of each of the two installation components 1. A connecting mechanism 5 is installed on the opposite sides of the outer surfaces of the installation components 1 and 2 3 located on the same side. Anti-tipping mechanisms 8 are symmetrically installed on the lower sides of the opposite surfaces of the two installation components 1. A scissor-type telescopic guardrail 2 is installed on the opposite sides of the two installation components 1. A scissor-type telescopic guardrail 4 is installed on the opposite sides of the two installation components 2 3. Warning mechanisms 6 are provided on the opposite sides of the rear ends of the scissor-type telescopic guardrail 2 and 2 4.

[0026] In this embodiment, the raised base blocks 7 at the bottom of the two mounting components 1 are used to adapt to uneven ground. However, the thickness of the mounting components 1 is relatively thin, only needing to meet the normal adjustment thickness of the anti-tipping mechanism 8. The scissor telescopic guardrail 1 2 and the scissor telescopic guardrail 2 4 are horizontally installed between the two mounting components 1 1 and the two mounting components 2 3 respectively, forming a two-layer protective structure. Its working principle is based on the classic scissor linkage mechanism, namely the X-shaped cross linkage. By changing the included angle between the linkages, a large range of telescopic changes in the length of the guardrail can be achieved.

[0027] The connecting mechanism 5 is used to firmly connect the installation component 1 and the installation component 3 into a whole column, ensuring the installation stability and overall structural strength of the upper guardrail;

[0028] Warning device 6 provides highly identifiable safety warnings at night or in low-visibility environments by combining active light emission and passive reflection.

[0029] The anti-tipping mechanism 8 is installed at the bottom of the device and can actively adjust the support range according to the wind force, dynamically enhancing the device's wind resistance and overall stability to prevent tipping.

[0030] For details, please refer to Figure 1 and Figure 2 In this embodiment, both mounting components 1 are equipped with raised base blocks 7 at their bottoms;

[0031] When in transport or storage, this device is in a fully folded state. At this time, the angle between the cross links of scissor-type telescopic guardrail 1 and scissor-type telescopic guardrail 2 is the smallest, the overall length is the shortest, the space occupied is small, and it is easy to handle and transport.

[0032] During on-site positioning, the two folded installation components 1, along with the pre-installed installation component 3 and the guardrail, are transported to the designated protection position in the highway pit. The two components are then placed symmetrically left and right according to the required protection length.

[0033] The operator pulls the two installation components 1 horizontally in opposite directions. Under the action of the pulling force, the cross linkage mechanism inside the scissor telescopic guardrail 12 and scissor telescopic guardrail 24 starts to move together. The included angle between the links gradually increases, thereby driving the two installation components 1 and 2 to separate synchronously. The overall length of the device extends rapidly until the predetermined protection length is reached.

[0034] Further reference Figure 1 and Figure 4 In this embodiment, each of the two connecting mechanisms 5 includes two threaded sleeve seats 501. The two connecting mechanisms 5 are arranged symmetrically from left to right. The two threaded sleeve seats 501 located on the same side are arranged symmetrically from top to bottom. The two threaded sleeve seats 501 located on the same side are respectively installed on the opposite side of the outer surface of the mounting component 1 and the mounting component 2 3 on the same side. The inner surface of the two threaded sleeve seats 501 is jointly installed with a fixing bolt 502.

[0035] After the device is deployed, the mounting component 1 and mounting component 3 located on the same side are fixed together by the connecting mechanism 5. The fixing bolts 502 are screwed into the upper and lower threaded sleeve seats 501 respectively and tightened, which rigidly connects the originally separate upper and lower parts to form a stable integral column, greatly enhancing the structural rigidity and impact resistance of the device in the vertical direction.

[0036] Further reference Figure 1 , Figure 3 and Figure 4 In this embodiment, each of the two warning mechanisms 6 includes two power supply devices 601. The two power supply devices 601 are respectively installed at the rear end of the two mounting components 1 or the two mounting components 3. A light panel 602 is installed at the rear end of each of the power supply devices 601. The two light panels 602 located at the same end have elastic reflective light strips 603 symmetrically installed on their opposite surfaces.

[0037] The power supply device 601 can automatically activate the light panel 602 to emit light via the controller, or it can be manually activated according to construction needs. The light panel 602 emits high-brightness active light, forming a conspicuous light strip to warn pedestrians and vehicles at a distance. At the same time, the elastic reflective light strip 603 installed between the two light panels 602 can efficiently reflect the light back when it is illuminated by vehicle headlights, forming a strong passive reflective warning. This dual warning mode of "active light emission + passive reflection" greatly improves the visibility and safety of the device under various lighting conditions.

[0038] The warning mechanism 6 is designed to address the issue of insufficient light during nighttime construction, a major factor significantly increasing construction safety risks. The warning mechanism 6 effectively compensates for this by providing light warnings, helping pedestrians and vehicles to promptly identify the construction area and reducing accidents. Furthermore, the light warnings are highly recognizable and visible from a distance. Compared to traditional static warning signs, dynamic or high-brightness lights are more likely to attract the attention of pedestrians and drivers, especially at night or in low-visibility environments, effectively alerting those in the vicinity to the construction area.

[0039] Example 2: Based on Example 1, this example adds an anti-tipping mechanism 8 to protect the bottom of the fence device. By setting the anti-tipping mechanism 8, construction safety hazards can be reduced, and the tipping of the fence may cause the protection of the construction area to fail, thereby threatening the safety of pedestrians and construction workers.

[0040] For details, please refer to Figure 1 , Figure 4 and Figure 5 In this embodiment, both anti-tipping mechanisms 8 include a dual-drive motor housing 801. The two dual-drive motor housings 801 are respectively installed on the lower side of the opposite face of the two mounting components 1. Threaded rods 802 are symmetrically installed on the outer surface of the dual-drive motor housing 801. Support bearing supports 803 are provided on the opposite sides of the outer surface of the two threaded rods 802. Movable seats 805 are provided in the middle and rear parts of the outer surface of the two threaded rods 802. Limit bearing supports 804 are installed on the opposite sides of the outer surface of the two threaded rods 802.

[0041] Further reference Figure 1 , Figure 4 and Figure 5 In this embodiment, a number of movable seats 805 are each equipped with a triangular limiting block 806 on the side away from the mounting component 1 on the same side. The two triangular limiting blocks 806 on the same side are symmetrically arranged front and back. The bottoms of the two limiting bearing supports 804 on the same side are respectively installed on the opposite side of the outer surface of the two supporting bearing supports 803 on the same side.

[0042] According to the on-site wind conditions, the operator starts the dual drive motor in the dual drive motor box 801 through the controller. The dual drive motor synchronously drives the threaded rods 802 on both sides to rotate. The movable seat 805 on the threaded rod 802 cannot rotate due to the guidance restriction of the support bearing seat 803, and can only move in a straight line along the threaded rod. When the motor rotates forward, the movable seat 805 drives the triangular limit block 806 at its end to move horizontally away from the installation component 1.

[0043] As the two triangular limiting blocks 806 extend outwards in sync, the bottom support area of ​​the device increases significantly. The bottom surface of the triangular limiting block 806 contacts the ground, forming a stable support base. This effectively lowers the overall center of gravity of the device and increases the anti-overturning moment, thereby resisting the attack of strong winds and ensuring that the device remains stable and does not fall.

[0044] When the wind is weak, or when working in a narrow construction area, the dual drive motor can be reversed by the controller, driving the threaded rod 802 to rotate in the opposite direction, causing the moving seat 805 and the triangular limit block 806 to retract inward, reducing the space occupied by the device and avoiding unnecessary interference with traffic.

[0045] The anti-tipping mechanism 8 is designed to be adjustable as needed. When the wind is strong, the distance between the two triangular limit blocks 806 at the same location can be extended, thereby significantly enhancing the support area and stability of the bottom of the guardrail, effectively resisting the influence of wind in the external environment, and preventing the guardrail from tipping over due to wind. When the wind is weak or space is limited, the distance can be flexibly reduced. This adjustability allows the device to adapt to various construction environments. By setting the anti-tipping mechanism 8, construction safety hazards can be reduced, and the tipping of the guardrail can be prevented from causing the protection of the construction area to fail, thereby threatening the safety of pedestrians and construction workers.

[0046] After construction is completed, operate in reverse order: turn off the warning mechanism 6, control the anti-tipping mechanism 8 to fully retract the triangular limit block 806, loosen the fixing bolt 502 of the connecting mechanism 5, release the rigid connection between the upper and lower columns, push the two installation components 1 inward, and the scissor telescopic guardrail 2 and scissor telescopic guardrail 4 will automatically fold and retract to their minimum length under the action of the linkage mechanism. Move the folded device away from the site to complete the recycling.

[0047] In this solution, the thread directions of the two threaded rods 802 located on the same side are opposite. The outer side of several threaded rods 802 is provided with a spiral steel strip type screw protective sleeve of the prior art to prevent dust from entering the thread groove and to ensure the normal transmission of this structure.

[0048] The dual-drive motor housing 801 in this solution includes an existing mounting housing, a dual-drive motor, and a controller. The dual-drive motor and controller are installed inside the mounting housing. The controller here can be an existing motor controller that is compatible with the dual-drive motor and can control the switching and rotation speed of the dual-drive motor.

[0049] The installation components 1, 2, 3, and 4 in this solution work together to form a foldable and retractable protective fence. The above mechanism includes the following structures and implementation principles in the prior art:

[0050] Support base: Used to secure the bottom of the guardrail and ensure its stability. The support base usually includes adjustable legs or fixing devices to adapt to the needs of different ground conditions.

[0051] Connectors: Used to connect the telescopic frame and the support base to ensure the guardrail remains structurally stable during expansion and contraction. Connectors are usually made of high-strength materials to withstand external loads.

[0052] Locking device: Used to fix the telescopic length of the guardrail and prevent it from moving accidentally during use. Locking devices generally include pins, buckles or screw fasteners.

[0053] Guide device: Used to guide the extension and retraction direction of the guardrail to ensure its smooth movement. The guide device is usually composed of slide rails or rollers.

[0054] The extension and retraction action is achieved by the linkage of the cross links. The guardrail can freely switch between extending and retracting. When an external force is applied, the angle between the links changes, thereby realizing the extension and retraction of the guardrail.

[0055] Support and stability: The support base ensures the guardrail remains stable on different ground surfaces by adjusting the height or angle of the support legs. At the same time, the locking device fixes the position of the guardrail after it is unfolded to prevent displacement due to external forces.

[0056] Guiding and limiting: The guiding device ensures that the guardrail moves in a predetermined direction during the extension and retraction process, avoiding structural deformation or jamming due to uneven force. At the same time, the limiting device is used to limit the maximum extension and retraction range of the guardrail to protect the structure from damage.

[0057] In summary, scissor-type telescopic barriers achieve flexible telescopic functionality and stable support through their unique mechanical linkage structure and support components.
