The invention discloses a telescopic rotating guardrail of a self-propelled guardrail. The telescopic rotating guardrail is arranged on the upper side of a movable base internally provided with a storage battery and comprises a fixed guardrail body, a rotating shaft and a rotating guardrail body, the fixed guardrail body is fixedly arranged on the upper side of the movable base, and the fixed guardrail body comprises two supporting rods located at the two ends and a blocking guardrail body arranged between the two supporting rods. First supporting plates are fixedly arranged at the upper ends and the lower ends of the supporting rods correspondingly, and a first servo motor electrically connected with the storage battery is arranged on the upper side of the first supporting plate at the upper end. The rotating shaft is rotationally arranged between the two first supporting plates, the output end of the first servo motor penetrates through the first supporting plate on the upper side and is connected with the rotating shaft to drive the rotating shaft to rotate, and sliding ways with opposite openings are fixedly arranged at the upper end and the lower end of the rotating shaft correspondingly. The angle of the guardrail is adjusted according to specific conditions, so that the form of the guardrail in a use state better meets actual requirements, the guardrail is more convenient to store, and the width requirement of a storage space is reduced.
Description
technical field [0001] The invention relates to the field of safety facilities, in particular to a retractable rotating guardrail of a self-propelled guardrail. Background technique [0002] Guardrails are widely used in roads, municipal engineering, airports and other occasions to protect the safety of equipment and personnel and to guide the flow of people. [0003] The structure of the existing guardrail is relatively fixed, and it is impossible to adjust the shape of the guardrail according to the specific situation, which is prone to unreasonable situations when placed, and when it is stored after use, because it cannot be stacked, it takes up a lot of space. Contents of the invention [0004] The purpose of the present invention is to provide a self-propelled guardrail with a retractable rotating guardrail, which can adjust the angle of the guardrail according to the specific situation, so that the shape in the use state is more in line with the actual needs, and the...
