Abstract

The invention relates to a well mouth safety door, in particular to a well mouth safety door with a locking device. The well mouth safety door comprises a door frame and a door body, multiple transverse handrails and multiple longitudinal handrails are welded crosswise to form the door body, a travel switch and a sensor are arranged on the door frame, the travel switch and the sensor are correspondingly connected with a PLC control device, the PLC control device is connected with an elevator, a buzzer and an LED lamp are further arranged on the door frame, and the buzzer and the LED lamp are connected with the PLC control device. According to the well mouth safety door, the adopted door body is firm and high in safety performance; the effects of being easy to install, low in cost, easy tooperate and capable of effectively avoiding the potential safety hazard that the door body is not tightly closed are achieved; and when the elevator falls into the door body, an operator can be reminded, and the visual field is clear.

Description

technical field [0001] The invention relates to a wellhead safety door, in particular to a wellhead safety door with a locking device. Background technique [0002] In order to ensure the safety of lifting operations and prevent personal or equipment accidents, necessary safety facilities must be installed at each wellhead in the cage lifting system. Safety doors must be installed on the surface and at the wellheads in the middle section to prevent personnel from entering dangerous areas or transport equipment from rushing into the wellbore, resulting in accidents of personnel or equipment falling into the well. The safety performance of the safety door needs to be further improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a wellhead safety door with a locking device, which has a solid door body and high safety performance; easy installation, low cost, simple operation, and can effect...
