Portal crane operator fatigue monitoring and early warning device

Abstract

The invention discloses a portal crane operator fatigue monitoring and early warning device. The device comprises a portal crane, the portal crane is provided with a square groove, a supporting columnis in clamping connection with the interior of the square groove, the supporting column is provided with a circular groove, the interior of the circular groove is rotatably sleeved with a cylinder, aconnection rod is fixedly connected with the lower end of the cylinder, the interior of the connection rod is fixedly sleeved with a positioning shaft, the outer side of the positioning shaft is rotatably sleeved with a shaft seat, and a camera is fixedly connected with the left end of the shaft seat; and a gear is fixedly connected with the tail end of the positioning shaft, a supporting sleeveis fixedly connected with the surface of the shaft seat, a cylinder body is connected with the interior of the supporting sleeve through a thread, the cylinder body is provided with a limiting groove,the interior of the limiting groove is slidably sleeved with a square rod, and a clamping sleeve is fixedly connected with the tail end of the square rod. The camera of the portal crane operator fatigue monitoring and early warning device is convenient to install, the angle can be adjusted stably and reliably, and the phenomenon of dislocation cannot occur.

Description

technical field [0001] The invention relates to the technical field of door machine equipment, in particular to a fatigue monitoring and early warning device for door machine operators. Background technique [0002] The door crane is a commonly used construction machine, and the use of the door crane needs to be operated by an operator to realize the lifting of heavy objects by the door crane. But after working continuously for a long time, the operator will inevitably get tired, which is easy to cause major accidents. With the continuous advancement of science and technology, currently most operators are monitored through cameras. When the operator is fatigued, the buzzer alarm in the door operator will sound to remind the operator and improve the safety of the operator. [0003] But common camera is inconvenient when installing, and adopts multiple fastening screws to install. Moreover, when adjusting the angle of the existing camera, it is mostly adjusted through the da...

Problems solved by technology

[0003] However, it is inconvenient to install ordinary cameras, and it is necessary to use multiple fastening screws for installation

Moreover, when adjusting the angle of the existing camera, most of them are adjusted through the damping shaft. The damping shaft can be adjusted, but the structure is unstable, and vibration will be generated when the door operator is working, which will easily cause the camera to shift, resulting in failure to monitor the operator.
