Description

Technical Field

[0001] This utility model relates to the field of municipal road construction technology, and more specifically, to a protective barrier for municipal road construction. Background Technology

[0002] Municipal road construction refers to the construction, renovation, and maintenance of roads within a city, and is an important component of urban infrastructure development. These projects typically include new road construction, pavement repair, sidewalk paving, traffic sign and marking installation, and drainage system construction, aiming to improve urban traffic conditions and enhance the safety and convenience of citizens' travel.

[0003] According to patent publication number CN108868313A, published on 2018-11-23, a protective barrier for municipal road construction includes a fixed base with a cavity inside. A partition adapted to the cavity is fixedly connected inside the cavity. A forward and reverse motor is fixedly connected to the right side of the partition. The output end of the forward and reverse motor passes through the partition and extends to the left side of the partition. A threaded rod is fixedly connected to the output end of the motor. A first bearing is fixedly embedded in the inner wall of the cavity. The outer surface of the left end of the threaded rod is fixedly connected to the inner ring of the first bearing. A threaded ring is fitted onto the outer surface of the threaded rod, and the inner ring of the threaded ring is threadedly connected to the outer surface of the threaded rod. This protective barrier for municipal road construction effectively prevents the slider from slipping off the track due to accidental movement of the threaded ring during operation, thus ensuring the normal use of the barrier. It not only prevents pedestrians from climbing over the barrier but also facilitates passage for construction workers, making it convenient to use. These guardrails cannot be connected and combined together. Each guardrail cannot be connected and combined with another. This not only limits their flexible application under different length requirements, making it difficult to form a continuous and effective barrier when setting up a protective area over a long distance, thus affecting the protective effect; at the same time, when multiple guardrails are placed side by side, they are easily damaged or displaced when they encounter external impacts (such as vehicle collisions) due to the lack of connection between adjacent ones, reducing the stability and safety of the overall structure.

[0004] Therefore, it is necessary to design a protective barrier for municipal road construction that can be connected. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the technical problem to be solved is to provide a guardrail for municipal road construction.

[0006] The technical solution of this utility model is: a guardrail for municipal road construction, including a guardrail, a first protective plate, an mounting plate, a first connecting block, a second connecting block, a sliding rod, and a return spring. The mounting plates are symmetrically connected to the guardrail, and the first protective plates are connected between the mounting plates. The first connecting block is connected to the left side of the guardrail and has a slot. The second connecting block is connected to the right side of the guardrail, and a sliding rod is slidably connected to the second connecting block. The sliding rod can fit into the slot, and a return spring is connected between the sliding rod and the second connecting block.

[0007] Furthermore, it also includes mounting covers, which are symmetrically installed on the guardrail, and each mounting cover contains an alarm component.

[0008] Furthermore, the alarm assembly includes a flashing light, a speaker, an infrared sensor, and a central controller. The flashing light is mounted on the top of the mounting cover, and the speaker, infrared sensor, and central controller are connected inside the mounting cover. The flashing light, speaker, and infrared sensor are all electrically connected to the central controller.

[0009] Furthermore, reflective strips are also included, with reflective strips symmetrically connected on the guardrail.

[0010] Furthermore, it also includes counterweights. The guardrail is equipped with a first counterweight, and the counterweights on the two guardrails that are subsequently connected are not located on the same side.

[0011] Furthermore, it also includes a second protective plate, which is connected to the left side of the guardrail.

[0012] The beneficial effects of this utility model are:

[0013] This invention, by installing a first connecting block and a second connecting block, releases the sliding rod, and the return spring returns the sliding rod to its original position, engaging with the slot, thereby fixing the first connecting block and the second connecting block together. This connects two guardrails together. The above steps are repeated to connect all other guardrails together, making it less likely for the guardrails to be damaged or shifted, effectively improving the stability and safety of the overall guardrail structure.

[0020] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0021] Example: A protective barrier for municipal road construction, such as... Figures 1-5 As shown, the device includes a guardrail 1, a first protective plate 4, a mounting plate 41, a first connecting block 7, a second connecting block 8, a sliding rod 9, and a return spring 10. Mounting plates 41 are symmetrically connected to the left and right sides of the guardrail 1. The first protective plate 4 is connected between the two mounting plates 41. The first protective plate 4 effectively blocks gravel or other impurities generated during construction, preventing them from being ejected from the construction area and hitting pedestrians or vehicles on the road, thus effectively improving the protective function of the device. The left side of the guardrail 1 is connected to the first connecting block 7, which has a slot 71. The right side of the guardrail 1 is connected to the second connecting block 8, which has a sliding rod 9 that slides back and forth. The sliding rod 9 can engage with the slot 71. A return spring 10 is connected between the sliding rod 9 and the second connecting block 8 via a spring seat. When using this device, first adjust the settings according to the requirements of the guardrail 1. The required length of the protective area determines the number of guardrails 1 needed. These guardrails 1 are then transported to the protected area and placed there. First, the left side of one guardrail 1 is moved towards the right side of another. When the first connecting block 7 aligns with the second connecting block 8, the sliding rod 9 is pulled outwards, stretching the return spring 10. The guardrails 1 are then moved further until the first connecting block 7 is fully inserted into the second connecting block 8. At this point, the sliding rod 9 is released, and the return spring 10, carrying the sliding rod 9, returns to its original position and engages with the slot 71, thus fixing the first connecting block 7 and the second connecting block 8 together. This connects two guardrails 1 together. The above steps are repeated to connect all the remaining guardrails 1. This process makes it difficult for the guardrails 1 to be damaged or shifted, effectively improving the stability and safety of the overall guardrail structure.

[0022] like Figure 2 and Figure 3 As shown, it also includes mounting covers 2. Mounting covers 2 are symmetrically provided on the guardrail 1, and each mounting cover 2 is provided with an alarm component for alarm.

[0023] like Figure 2 and Figure 3 As shown, the alarm component includes a flashing light, a speaker, an infrared sensor, and a central controller. The flashing light is mounted on the top of the mounting cover 2 via a fastener. The speaker, infrared sensor, and central controller are connected inside the mounting cover 2. The flashing light, speaker, and infrared sensor are all electrically connected to the central controller. When the infrared sensor detects a pedestrian or vehicle passing around the guardrail 1, it will transmit information to the central controller. After receiving the information, the central controller will control the flashing light to flash and the speaker to emit a voice reminder. This alarm component is more effective when working at night, thus enabling the device to have an alarm reminder function, effectively reducing the occurrence of accidents, and further improving the protective function of the device.

[0024] like Figure 1-5 As shown, it also includes reflective strips 3. The guardrail 1 is symmetrically connected with reflective strips 3 to remind pedestrians and vehicles, which enhances the presence of the device at night.

[0025] like Figures 1-3 and Figure 5 As shown, it also includes a counterweight 6. The first counterweight 6 is installed on the guardrail 1. The counterweights 6 on the two guardrails 1 that are subsequently connected are not located on the same side. When a pedestrian or a small vehicle collides with the guardrail 1, the first counterweight 6 installed in a misaligned manner will correct the tilted position of the guardrail 1, so that pedestrians and small vehicles are less likely to knock down the guardrail 1, preventing pedestrians or small vehicles from directly rushing into the construction area and ensuring the personal safety of pedestrians.

[0026] like Figures 1-3 As shown, it also includes a second protective plate 5. The left side of the guardrail 1 is connected to the second protective plate 5, which can prevent gravel or other impurities generated during construction from popping out from the connection of the guardrail 1.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
