Description

Technical Field

[0001] The present invention relates to the technical field of elevator speed limiters, and in particular to a remote reset elevator speed limiter. Background Art

[0002] At present, the elevator speed limiter is one of the safety control components in the elevator safety protection system. When the elevator car is overspeeding or even in danger of falling during operation for any reason, and all other safety protection devices do not work, the speed limiter and the safety clamp will act in conjunction to stop the elevator car. It is a safety protection device for the elevator. It monitors and controls the speed of the car at any time. When an overspeed occurs, that is, 115% of the rated speed of the elevator, it can send a signal in time, and then produce a mechanical action to cut off the power supply circuit and brake the traction mechanism. If the elevator still cannot brake, the safety clamp installed at the bottom of the car will force the car to stop. The speed limiter is the command issuer, and the safety clamp is the executor. The joint action of the two has led to the saying of safe elevators. The speed limiter safety clamp system is an indispensable safety device for elevators. When the elevator is overspeeding, out of control or the suspension device is broken, the speed limiter safety clamp device quickly stops the elevator car on the guide rail and keeps it stationary, thereby avoiding casualties and equipment damage accidents. The elevator is a manned vertical transportation tool, and safe operation must be put first. In order to ensure the safe operation of the elevator, the prevention of dangers must be fully considered in all aspects of design, manufacturing, installation, etc., and special safety devices should be set up for various possible dangers. The speed limiter safety clamp system is a safety device that protects the elevator when overspeed or rope breaks. Whether the system can work properly depends not only on design and manufacturing, but more importantly on daily maintenance.

[0003] The prior art authorization announcement number is: CN218290036U, a remote reset elevator speed limiter, including a body, a ventilation hole is opened in the body, an LED display screen is arranged on the body, a control key is arranged on the body, a ventilation mechanism is arranged on the body, a dust cleaning mechanism is arranged on the body, the ventilation mechanism includes a fan, an end plate, a card plate, a guide column and an elastic airbag, and the body is slidably connected with a fan. The utility model can ventilate the inside of the body through the coordinated use of the fan and the ventilation hole to avoid the problem of moisture regeneration inside the body, and can push the end plate to move downward to drive the card plate to slide, and the elastic airbag is deformed by force, so that the card plate is separated from the fan, which is convenient for people to dismantle and repair the fan. However, when the utility model uses the fan to ventilate the interior, the rotation of the fan will bring dust in the air into the body, affecting the smoothness of the internal components of the body and accelerating the aging of the internal components.
