Movable anti-penetrating guardrail for municipal highway engineering

Abstract

The invention discloses a movable anti-penetrating guardrail for municipal highway engineering, and belongs to the technical field of guardrails for municipal highway engineering. The movable anti-penetrating guardrail used for municipal highway engineering comprises a movable block, a storage and transportation box is arranged on the rear side of the right end of the movable block, rolling wheels are arranged on the bottom faces of the movable block, the storage and transportation box and a connecting block, and an output shaft of a first motor penetrates through the inner wall of a machine cavity, extends into a through groove and is connected with a gear A in a sleeved mode; a plurality of connecting rods are linearly and rotationally connected into the through groove at equal intervals through connecting shafts, guardrail plates are fixedly arranged at one ends of the connecting rods through inclined blocks, through cooperation of the structures, when the device is used, only the storage and transportation box needs to be pushed to the needed position, at the moment, the connecting rods are unfolded, the guardrail plates are directly unfolded, and an anti-penetrating guardrail is formed; the situation that a plurality of independent guardrail frames can only be used after being installed is avoided, the use number is small, conveying is convenient, independent installation is not needed, manpower and material resources are saved, efficiency is improved, and anti-penetrating work can be carried out in time.

Description

technical field [0001] The invention relates to the technical field of municipal highway engineering guardrails, and more specifically relates to a mobile anti-penetration guardrail used in municipal highway engineering. Background technique [0002] Municipal engineering refers to municipal infrastructure construction projects. In my country, municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects, and projects that are closely related to life Various related pi...

Problems solved by technology

The prior art publication number is CN207619889U, which provides a mobile anti-penetration guardrail for municipal highway engineering. The device is provided with an oil cylinder and a movable column, and the oil in the oil cylinder moves upward against the movable column, so that the anti-penetration guardrail can be adjusted. The height of the luminous warning sign is set up, and the luminous warning sign can warn passers-by not to climb and cross the boundary. Although the device has many beneficial effects, the following problems still exist: the device needs to be built and connected through multiple separate guardrail frames, and the installation It can only be used later, the quantity is too much to transport, the installation process is long, and it wastes manpower and material resources. This entry leads to the occurrence of dangerous situations, and the prior art publication number is CN113005957A, and the document has the same problem;

[0003] In addition, in the structure of the retractable mobile guardrail in the existing patented technology, each guard plate can reach a flat alignment state after reaching the maximum stroke, and cannot The splicing and alignment of the protective panels is realized at different telescopic length positions. Therefore, the traditional protective fence structure must reach a fixed length to achieve the anti-passing effect, and it cannot be applied to different small areas.
