Small-eye guardrail linkage locking protection device

Abstract

The small-hole guardrail linkage locking protection device comprises a belt conveyor main body, a protection guardrail, a guardrail door and a tearing protection main line box, the belt conveyor main body is located on the inner side of the protection guardrail, the guardrail door is hinged to the protection guardrail, the tearing protection main line box is fixedly connected to the front face of the protection guardrail, and the tearing protection main line box is fixedly connected to the front face of the protection guardrail. The front face of the guardrail door is fixedly connected with a tearing protection auxiliary wire box. The belt conveyor has the beneficial effects that the guardrail door is opened, the tearing protection main wire box and the tearing protection auxiliary wire box are far away from each other, and the infrared emitter and the infrared receiver on the tearing protection main wire box are staggered and disconnected, so that the tearing protection main wire box can control the belt conveyor main body to disconnect a power supply, and workers can safely and efficiently clean accumulated waste rocks clamped in holes; the safety coefficient of personnel is high, time is saved, manual emergency stop and contact stop switch locking are not needed, the application range is wide, the applicability is high, and the device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of protective guardrails, in particular to a linkage locking protection device for small eye guardrails. Background technique [0002] Guardrails refer to industrial "guardrails". 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. Guardrails can be seen everywhere in our lives. Depending on the height of the guardrail, the price per meter of length will also vary. [0003] The construction of small eyes in the work area is often used. When gangue or jammed holes are accumulated in the small eyes, it needs to be handled manually. It needs to be pulled to an emergency stop or go to the switch to turn off the power and not lock. Too much gangue accumulates in an instant, which increases the difficulty of cleaning and safety. For this reason, we A small eye guardrail linkage ...
