Problems solved by technology

[0002] At present, in the existing safety protection devices of vertical elevators, the speed limiter and safety gear of the anti-overspeed and anti-fall safety devices are mechanical, which have disadvantages such as low sensitivity, slow response speed, and too blunt braking action. During the protection process, people will be left with the consequences of mental shock and physical injury, and the protection content is single and cannot be extended to other protection purposes

Embodiment Construction

[0010] Install the safety gates at appropriate positions on the left and right sides of the car body, matching with the left and right guide rails. Such as figure 1 , figure 2 shown.

[0011] exist figure 1 In the shown embodiment, when the electromagnetic coil (1) is energized, the electromagnetic force (P 1 ) under the action of the electromagnet core pole (2) pulls in, and at the same time the electromagnetic force (P 1 ) is applied to the electromagnetic power arm (3), through the principle of leverage, the electromagnetic force (P 1 ) becomes the braking force (P 2 ), at braking force (P 2 ) under the action of the friction plate (7) and the guide rail (9) to generate a huge brake friction force, which firmly clamps the guide rail (9), thereby achieving the purpose of deceleration, speed limit, braking and locking the car; the electromagnetic coil ( 1) Under the control of the control circuit with variable output function, a variable electromagnetic force (P) is g...

Abstract

The invention discloses a multipurpose electromagnetic safety brake for a vertical elevator. The multipurpose electromagnetic safety brake is a safety protection device for the vertical elevator. A mechanical mode of an existing elevator overspeed preventing and falling preventing safety device is upgraded into an electromechanical mode, and the characteristics that sensitivity is high, the reaction speed is high, the protection purposes are wide, and the protection process is soft are achieved. The multipurpose electromagnetic safety brake is a multipurpose safety protection device, electromagnetic force generated by an electromagnet serves as braking power, under control of a control circuit with the corresponding control function, the protection functions such as the multiple purposes of an elevator car, soft decelerating, speed limiting and braking locking are achieved through the changes of the braking effect of a guide rail, and the multipurpose electromagnetic safety brake is suitable for elevator running preventing, mistaken starting preventing, mistaken door opening preventing, overspeed preventing, falling preventing, offside preventing and the like.

Description

technical field [0001] The invention relates to a safety protection device for a vertical lifting elevator. Background technique [0002] At present, in the existing safety protection devices of vertical elevators, the speed limiter and safety gear of the anti-overspeed and anti-fall safety devices are mechanical, which have disadvantages such as low sensitivity, slow response speed, and too blunt braking action. During the protection process, people will be left with mental shock and physical harm, and the protection content is single and cannot be extended to other protection purposes. Contents of the invention [0003] In order to overcome the deficiencies of existing elevator anti-overspeed and anti-fall safety devices, the present invention provides a multi-purpose electromagnetic safety gate for vertical lift elevators. The electromagnetic safety gate is electromechanical, with high sensitivity, fast response, and wide protection applications The protection process ...
