Elevator safety level apparatus with multiple startup modes

Abstract

The invention relates to an elevator safety lever device capable of setting various starting modes. The safety lever device comprises safety levers, a lever sleeve, a reciprocating device, an electronic speed limiter, a motor, pier posts and so on, wherein the safety levers are arranged on the left and the right on or below an outer frame of an automobile; the pier posts are arranged on the shaft wall of an elevator; and the electronic speed limiter is arranged inside an elevator machine room. When an elevator is out of control and fallen down or pushed to the top at an excessive speed, the safety levers can be bounced out and stopped by the pier posts on both sides of the shaft wall; braking of the automobile can not be influenced even a guide rail, a steel rope, safety tongs and so on are stained with a large quantity of oil or humidified; and staffs are easy to go out because a motionless automobile door faces to a floor door. The device makes up for the blank in the aspect of using the safety lever device on the elevator, and is provided with various structural forms for people to select and set. The device can overcome the defect that the automobile door does not always face to the floor door when the safety tongs of the elevator brake, and can also overcome the defect that braking of the elevator is influenced because the steel rope, the guide rail and so on are stained with a large quantity of oil and too humidified.

Description

technical field [0001] The invention relates to a safety device used on a vertical elevator, in particular to a safety bar device for braking the overspeed running of the car. Background technique [0002] The safety gear device used in the current elevator has the following defects: 1. When the safety gear brakes the car that is rushing to the top or falling at an overspeed, the car stops at random, and the car door does not necessarily face the floor door. 2. If the air is humid or oily, the brakes, rope clamps, safety gear, etc. will slip easily, which is not safe, and the possibility of failure is higher. Big. Contents of the invention [0003] The purpose of the present invention is to provide an elevator safety bar device which can be set in various starting modes. When the elevator traction wire rope breaks accidentally or the car runs out of control to the top or falls at an overspeed, the safety bar in this device will pop out and be held by the pillars on both ...
