Composite guardrail with automatic closing function

Abstract

The invention discloses a composite guardrail with an automatic closing function. The composite guardrail with the automatic closing function comprises a first mounting frame and a second mounting frame; two connecting pipes are arranged on one surface, corresponding to the second mounting frame, of the first mounting frame; first mounting grooves are formed in the corresponding surfaces of the two connecting pipes; adjusting pipes are connected to the bottom ends of the first mounting grooves through electric telescopic rods; guardrail pipes are arranged on the connecting pipes on the two sides of the adjusting pipes; the guardrail pipes are also arranged on the adjusting pipes; and openings are formed in positions, corresponding to the guardrail pipes on the adjusting pipes, of the connecting pipes. According to the composite guardrail with the automatic closing function, the electric telescopic rods are used as an acting force for opening and closing the guardrail so as to replace amotor; and therefore, the structure is simpler, and the mounting and overhauling are made convenient; and meanwhile, the electric telescopic rods cannot apply a over-large inertia force to the guardrail so that the service life of the guardrail is prolonged; and by setting a PLC controller, the composite guardrail can be automatically closed after being opened so that the use is made convenient for a user.

Description

technical field [0001] The invention relates to the technical field of composite guardrails, in particular to a composite guardrail with an automatic closing function. Background technique [0002] Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. Most of the guardrails are set as fixed and integrated structures, but in some special areas both need to use guardrails, At some point, people need to pass through. The guardrail used for access control is one of them. Most of the current access control guardrails use motors as the power to open and close the guardrail. Because the motor rotates faster, other equipment is needed. Adjust the speed of the motor to reduce the speed of the motor. Although this guardrail can be closed automatically, it has the problem of complex structure and inconvenient maintenance. Moreover, when the guardrail is o...
