Safety warning device used for elevator maintenance

Abstract

The invention belongs to the technical field of elevator maintenance and particularly relates to a safety warning device used for elevator maintenance. Specific to the problems that when an elevator is maintained nowadays, a warning board needs to be placed at an elevator gate on each floor, and time and labor are wasted, the following scheme is put forwards. According to the scheme, the safety warning device comprises door frame concrete and a door pocket connected to the door frame concrete in a sleeving manner. An installation groove is formed in the right side of the door frame concrete, and a coiling block is connected in the installation groove in a clamping manner. A rotating shaft is rotationally connected in the coiling block. A cloth bag roll is connected to the position, close to the bottom end, of the outer wall of the circumference of the rotating shaft in a sleeving manner, and a warning belt is wound around the outer wall of the circumference of the cloth bag roll. A cloth clamping bar is fixed to the end, away from the cloth bag roll, of the warning belt, and a connecting pillar is fixed to the side, away from the warning belt, of the cloth clamping bar. By means ofthe safety warning device used for elevator maintenance, after the warning belt is dragged out, a clamping bar can be plugged into the bar-shaped hole incidentally, afterwards, rotation is conductedby 90 degrees, then the end portion of the warning belt can be fixed, and therefore the warning belt stretches across the part between the two inner walls of the door pocket to achieve a blocking effect.

Description

technical field [0001] The invention relates to the technical field of elevator maintenance, in particular to a safety warning device for elevator maintenance. Background technique [0002] Regardless of whether it is an elevator for high-rise buildings or an escalator for shopping malls, it is necessary to suspend the use of the elevator after long-term operation failures and during regular maintenance. Warning signs need to be set up during elevator troubleshooting and maintenance to warn people not to take the elevator at this time . [0003] The common elevator warning sign adopts the commonly used foldable fence warning sign, which is light in weight and easy to carry and place, but its fence effect and warning effect are poor, especially underage children and illiterates cannot be accurately identified, and mobile warnings are prone to occur There are also some engineering warning signs that can be used for elevator maintenance warnings.

Problems solved by technology

[0003] The common elevator warning sign adopts the commonly used foldable fence warning sign, which is light in weight and easy to carry and place, but its fence effect and warning effect are poor, especially underage children and illiterates cannot be accurately identified, and mobile warnings are prone to occur There are also some engineering warning signs that can be used for elevator maintenance warnings. They are usually made of alloy materials, which can better block the elevator entrance and are not easy to move. The warning enclosure effect is better, but its quality It is heavy, inconvenient to transport, increases the workload of maintenance personnel, and is not convenient for large-scale use

In addition, the existing elevator maintenance warning signs can only be mechanically warned, and warning signs need to be placed at the elevator door of each floor, which is laborious
