Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a road construction safety warning device that facilitates the replacement of warning content, including a base plate 1. A counterweight 2 is fixedly installed on the top of the base plate 1. The addition of the counterweight 2 increases the overall weight of the device and improves its stability under wind and other external forces. A solar panel 3 is fixedly installed on the front side of the counterweight 2. The solar panel 3 is installed on the front side of the counterweight 2 to collect solar energy and convert it into electrical energy to provide power support for the electric push rod 63. This design is not only energy-saving and environmentally friendly, but also reduces the dependence on traditional power sources and improves the portability and flexibility of the device. Four moving wheels 4 are fixedly installed on the bottom of the base plate 1. The number of moving wheels 4 is four, and they are arranged in pairs symmetrically on the left and right. The moving wheels 4 enable convenient movement and facilitate rapid deployment at different construction sites.

A stabilizing plate 55 is fixedly installed on the bottom of the screw 53. When the handle 54 is turned, the screw 53 rotates and moves downward inside the threaded cylinder 52. The stabilizing plate 55 at the bottom of the screw 53 then descends until it is in close contact with the ground, providing additional support. By adjusting the stabilizing plates 55 of the two stabilizing assemblies 5, the device can be kept stable under different terrains and tilt angles.

[0025] The lifting assembly 6 includes a stabilizing frame 61. Two stabilizing frames 61 are fixedly installed on the top of the counterweight 2. A lifting plate 62 is slidably installed between the two stabilizing frames 61. An electric push rod 63 is fixedly installed on the top of the counterweight 2. The electric push rod 63 is electrically connected to a mobile power supply and is controlled by an external program. The output end of the electric push rod 63 is fixedly connected to the bottom of the lifting plate 62. When the electric push rod 63 is activated, its output end pushes the lifting plate 62 to slide up and down within the stabilizing frame 61. The lifting movement of the lifting plate 62 can be adjusted according to the actual needs of the installation mechanism 7 and the height of the warning sign to adapt to different line of sight requirements and construction environments.

[0026] A rectangular groove is provided on one side of the stabilizing frame 61, and the size of the rectangular groove is adapted to the lifting plate 62.

[0027] Preferably, the installation mechanism 7 includes a mounting frame 701. The mounting frame 701 is fixedly mounted on the top of the lifting plate 62. A U-shaped frame 702 extending to the bottom of the mounting frame 701 is slidably mounted on the top of the mounting frame 701. A horizontal plate 703 located at the bottom of the mounting frame 701 is fixedly mounted between the left and right sides of the inner wall of the U-shaped frame 702. Two limiting blocks 704 are fixedly mounted on the inner top wall of the U-shaped frame 702. Two bottom blocks 705 located inside the U-shaped frame 702 are fixedly mounted on the top of the mounting frame 701. A mounting hole 706 is opened inside the mounting frame 701. A moving plate 707 is slidably mounted inside the mounting hole 706. A baffle 708 is fixedly installed between the upper and lower sides of the inner wall of the mounting hole 706. A connecting rod 709 that passes through the baffle 708 and extends to the front of the mounting bracket 701 is fixedly installed on one side of the movable plate 707. A telescopic spring 710 is fixedly installed between the movable plate 707 and the baffle 708. The elastic coefficient of the telescopic spring 710 can be set according to requirements. A vertical plate 711 is fixedly installed at one end of the connecting rod 709. A pull ring 712 is fixedly installed on one side of the vertical plate 711. Four rectangular plates 713 are fixedly installed on the other side of the vertical plate 713. The top two rectangular plates 713 are respectively attached to the upper and lower sides of the horizontal plate 703.

[0028] Four rectangular plates 703 are distributed at equal intervals, two telescopic springs 710 are distributed symmetrically from left to right, the mounting bracket 701 is designed in the shape of an "I", and the baffle 708 has through holes inside that are adapted to the connecting rod 709.

[0029] When in use, move the device to a suitable location on the construction road, ensuring that the device is stable and easily noticed by passing vehicles and pedestrians. Depending on the ground conditions, adjust the height of the screw 53 by rotating the handle 54 to make the stabilizing plate 55 contact and compact the ground, ensuring the stability of the device during construction. Adjust the height of the lifting plate 62 by using the electric push rod 63, thereby adjusting the height of the installation mechanism 7 and the warning signs on it, ensuring that the warning signs are in a conspicuous position, easy for passing vehicles and pedestrians to notice. Select appropriate warning signs as needed and install them on the mounting frame 701 according to the working principle of the installation mechanism 7, ensuring that the warning signs are secure and not easily detached. Regularly inspect and maintain the device to ensure that it is in good working condition. The inspection includes, but is not limited to, the tightness and wear of components such as the stabilizing component 5, the lifting component 6, and the installation mechanism 7, as well as the working condition of the electric push rod.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] In summary, the road construction safety warning device for this project, through the installation mechanism 7, facilitates the replacement of different warning content. The U-shaped frame 702 is slidably installed on the mounting frame 701. The limiting block 704 and the bottom block 705 are respectively fixed to the inner top wall of the U-shaped frame 702 and the top of the mounting frame 701 for installing warning panels with different content. A movable plate 707 is slidably installed in the mounting hole 706. A telescopic spring 710 is provided between the movable plate 707 and the baffle 708, giving the movable plate 707 a certain degree of elasticity. When it is necessary to install or replace the warning signs, the operator can pull the vertical plate 711 and the connecting rod 709 through the pull ring 712. Move the movable plate 707 and the rectangular plate 713 to release the rectangular plate 713 from locking the horizontal plate 703. Then, slide the U-shaped frame 702 to the top position and place the new warning sign between the limit block 704 and the bottom block 705. Then, adjust the U-shaped frame 702 to the appropriate position and release the handle 712. Under the action of the telescopic spring 710, the rectangular plate 713 is reset, and the position of the horizontal plate 703 is fixed again. This achieves the purpose of easy replacement of warning content and solves the problem that the display board is a fixed structure, which cannot disassemble and replace the warning content. Only the whole device can be replaced to change different content, resulting in poor applicability.
