Flexible safety gear linkage mechanism for home elevator

Abstract

The invention discloses a flexible safety gear linkage mechanism for a home elevator. Left and right safety gears with gear bodies and lifting rods are arranged on left and right vertical beams of a cage respectively, and are linked through a linkage rod, wherein the lifting rods are linked with cranks to form a universal linkage mechanism through a linkage shaft; the linkage rod is provided with left and right pull rods; one end of the left pull rod is connected with the left crank linked with the lifting rod of the left safety gear, and the other end of the left pull rod is connected with a turnbuckle; one end of the right pull rod is connected with the right crank linked with the lifting rod of the right safety gear, and the other end of the right pull rod is connected with the left pull rod through the turnbuckle. The linkage mechanism has the advantages that the linkage mechanism is flexible and reliable in structure and higher in safety; the linkage mechanism is simple in design and high in practicability; the linkage mechanism is convenient to operate, and gaps between the safety gears and guide rails are relatively easy to regulate; the linkage mechanism is smaller in size and applicable to the home elevator; the linkage mechanism can be regulated leftwards and rightwards, and is difficult to lock.

Description

technical field [0001] The invention relates to a flexible safety gear linkage mechanism for a household ladder, which relates to a linkage mechanism that can be flexibly lifted and pulled on the household ladder safety gear, and the distance between the guide rail and the brake block of the safety gear is relatively easy to adjust and is not easy to be stuck. Background technique [0002] The elevator safety gear device is under the control of the speed limiter. When the elevator speed exceeds the limit speed set by the elevator speed limiter, or when the suspension rope breaks and relaxes, it will stop the car in an emergency and clamp it on the guide rail. A safety device on the It provides effective protection for the safe operation of the elevator, and is generally installed on the car frame or counterweight frame. Safety gear is divided into one-way safety gear and two-way safety gear, but due to the complicated manufacturing process, two-way safety gear has not yet b...

Problems solved by technology

[0008] At present, most safety gears of home elevators use bolts to adjust the free gap between the brake block and the guide rail. It is extremely troublesome to adjust and waste man-hours. Moreover, the free distance cannot be well controlled, and it is easy to get stuck, causing the safety gear to fail. According to the development trend of today's society and economy, saving working time and improving work efficiency is to liberate and develop productivity and create more surplus value for the company
