Description

Technical Field

[0001] This utility model relates to a safety warning device, specifically a safety warning device for municipal road and bridge construction. Background Technology

[0002] Warning devices are devices used to warn and indicate risks. During municipal road and bridge construction, they are essential to prevent unauthorized personnel from entering the construction site and causing safety accidents or disrupting the construction process. Therefore, warning devices are frequently used during construction to ensure the smooth progress of the work and prevent human interference. Existing construction safety warning devices are typically integrated structures, or the warning sign is installed and fixed to the support frame using bolts or other fasteners. Furthermore, most existing warning signs only have one type of safety warning slogan, making it difficult to quickly update the warning content when the road environment changes. Many warning signs also lack appropriate protective devices, such as wind and rain protection, resulting in excessive dust accumulation on the surface and poor warning effectiveness. Therefore, a new safety warning device for municipal road and bridge construction needs to be designed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a safety warning device for municipal road and bridge construction to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A safety warning device for municipal road and bridge construction includes a support plate, an mounting block mounted on the support plate, an mounting groove on the mounting block, a connecting block slidably mounted in the mounting groove, a connecting rod mounted on the connecting block, a positioning plate mounted on the end of the connecting rod away from the connecting block, a through hole for the positioning plate to pass through on the support plate, a movable wheel mounted on the bottom of the support plate, and a drive assembly mounted on the mounting block; a threaded rod is provided in the mounting groove, one end of the threaded rod is rotatably connected to the bottom wall of the mounting groove, and the other end is connected to the drive assembly, and the threaded rod is threadedly connected to the connecting block;

[0006] A support rod is installed on the mounting block. A placement plate is installed on the end of the support rod away from the mounting block. A placement slot is opened on the placement plate. A limit component is installed in the placement slot. An installation rod is installed on one side of the placement plate. A placement box is connected to the end of the installation rod away from the placement plate. A warning light is installed on the placement plate. A prompting component is provided at the bottom of the placement plate. The prompting component is connected to the drive component.

[0007] As a further embodiment of this utility model: the drive assembly includes a dual-axis motor, which is mounted on the mounting block. The output end of the dual-axis motor is equipped with a first drive shaft and a second drive shaft. The first drive shaft extends into the mounting groove and is connected to a threaded rod, and the second drive shaft is connected to the prompting component.

[0008] As a further embodiment of this utility model: the limiting component includes a telescopic member, which is symmetrically arranged in the mounting groove. One end of the telescopic member is connected to the side wall of the mounting groove, and the other end is connected to a clamping plate.

[0009] As a further embodiment of this utility model: the prompting component includes a gong, which is hinged to the bottom wall of the placement plate, and a striking rod is provided on one side of the gong, which is mounted on the second drive shaft.

[0010] As a further embodiment of this utility model: a lighting lamp is installed at the bottom of the placement plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the warning sign is placed in the placement slot. The installed telescopic component drives the connected clamping plate to move towards each other to clamp and fix the warning sign, improving its stability. When it needs to be replaced, the telescopic component drives the clamping plate away from the warning sign, making it easier to replace the warning sign. The placement box can be used to store frequently used warning signs. After the device is moved to the designated position by the moving wheels, the installed dual-axis motor drives the first drive shaft to rotate. The first drive shaft drives the threaded rod to rotate. The rotation of the threaded rod, under the action of the thread, drives the connecting block to move downward. The downward movement of the connecting block drives the positioning plate at one end of the connecting rod to move downward and contact the ground, thereby positioning the device. The installed warning light can serve as a warning. At the same time, the installed second drive shaft can drive the striking rod to rotate. The striking rod strikes the gong at regular intervals, which can further remind personnel unrelated to the construction, improving the warning effect of the device. Attached Figure Description
