Problems solved by technology
However, after the wheels of the movable temporary guardrail are braked, after the temporary guardrail is pushed by a relatively large external force, the wheels on the temporary guardrail will slide on the ground in a non-rotating manner, so that it is easy to cause the wheels to fall for a long time like this. The wear and tear of the wheel will cause the wheel to be worn into a non-circular shape, and the non-circular state of the wheel will easily cause bumps during the rolling process.

The invention belongs to the technical field of guardrails, in particular to a movable temporary guardrail for municipal engineering, which comprises a guardrail, a vehicle mechanism, an adjusting mechanism and a steering mechanism, wherein, after a brake plate is in downward pressure contact with the ground, there is a larger static friction force between the brake plate and the ground, so that the temporary guardrail of the invention cannot be easily pushed; The temporary guardrail of the invention has the braking effect of the traditional temporary guardrail. In addition, when the temporaryguardrail of the invention is still pushed by an external force after braking, The front wheel and the rear wheel can still roll, but the brake plate is worn, thereby avoiding the wear caused by thewheel sliding on the ground in a non-rotating manner in the traditional temporary guardrail, avoiding the wheel from being worn into a non-circular shape, and ensuring that the wheel can make the temporary guardrail run smoothly. The invention has the advantages of simple structure and good use effect.
Description
technical field [0001] The invention belongs to the technical field of guardrails, in particular to a movable temporary guardrail used in municipal engineering. Background technique [0002] At present, when municipal roads or pipelines are repaired, it is often necessary to isolate a certain area. At this time, the movable temporary guardrail can easily isolate the area to prevent non-staff personnel from entering. But in some special cases, non-staff also will push the temporary guardrail, in order to prevent the non-staff from pushing the temporary guardrail, so the wheels of the traditional removable temporary guardrails all have braking mechanisms. However, after the wheels of the movable temporary guardrail are braked, after the temporary guardrail is pushed by a relatively large external force, the wheels on the temporary guardrail will slide on the ground in a non-rotating manner, so that it is easy to cause the wheels to fall for a long time like this. The wear and...
