Self-rescue safety elevator for building

Abstract

The invention discloses a self-rescue safety elevator for building. The self-rescue safety elevator comprises an elevator body, a fixing plate is arranged on each of left and right sides of the elevator body, the side wall, facing the elevator body, of each fixing plate is fixedly connected with a plurality of triangular blocks uniformly from top to bottom, a plurality of rows of rectangular notches are uniformly formed in each of left and right side walls of the elevator body from top to bottom, a square sleeve is fixedly connected in each rectangular notch, a sliding square rod is connectedin each square sleeve through a first spring, and the outer end of each sliding square rod is fixedly connected with an inverted triangular block matched with the corresponding triangular groove; eachof the left and right side walls of the elevator body is fixedly connected with a first sliding rail, a retaining plate is slidably connected on the outer side of each first sliding rail through a first slider, and a plurality of through ports matched with the corresponding inverted triangular blocks are uniformly formed on each retaining plate; a pulling rope is fixedly connected at the top of each retaining plate, and the other end of each pulling rope penetrates the top wall of the elevator body to be connected into the elevator body. The retaining plate can be made to ascend by only pulling the pulling rope to be matched with the triangular blocks, the first springs are compressed reciprocatingly in the process when the elevator descends to decelerate the elevator, and momentary jamming is prevented.

Description

technical field [0001] The invention relates to a building elevator, in particular to a building self-rescue safety elevator. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. The vertical elevator has a car, the size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use the elevator as a general term for vertical transportation in buildings regardless of its driving mode. [0003] Elevators are generally used in high-rise buildings. Due to factors such as elevator aging or manufacturing defects, accidents such as sudden power failure and rapid fall may occur during the operation of the elevator. Passengers lack self-rescue measures after an ordinary elevator is...

AI Technical Summary

Problems solved by technology

[0003] Elevators are generally used in high-rise buildings. Due to factors such as elevator aging or manufacturing defects, accidents such as sudden power failure and rapid fall may occur during the operation of the elevator. Passengers lack self-rescue measures after an ordinary elevator is in distress, and can only rely on the brake of the elevator. The system performs emergency braking, and the automatic braking system of the elevator is easily damaged or out of control, and the braking effect is not good, so the elevator falls from time to time, posing a huge threat to the lives of passengers
