Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] Such as figure 1 As shown, an elevator anti-falling safety protection mechanism based on safety gear control includes a main draw beam 1 connected to a traction steel rope 9, a pair of main connecting rods 2 respectively hingedly installed at both ends of the main draw beam 1, and a main draw beam connected to the main draw beam 1. The strong spring 7 of the traction beam 1 and the car 6; the middle position of the main link 2 is movable with the car 6 to realize the rotation and translation of the main link 2, and its lower end is hingedly installed with the safety gear control rod 8; the main traction beam 1. When moving up and down along the direction of the traction force, it can dri...

Abstract

The invention discloses an elevator falling preventing safety protection mechanism based on safety tongs operation. The safety protection mechanism comprises a main draft sill connected with a dragging steel rope, a pair of main connecting rods hinged to the two ends of the main draft sill and a strong spring for connecting the main draft sill with a car platform sill; the middles of the main connecting rods are movably installed on the car platform sill so that the main connecting rods can rotate or move translationally, and the lower ends of the main connecting rods are hinged to operating levers of safety tongs; the main draft sill can drive the operating levers of the safety tongs to ascend or descend when moving up and down in the drag force direction to achieve actions of the safety tongs. The elevator falling preventing safety protection mechanism has the advantages that as the function of force is instantaneous, the safety tongs act faster and more timely instead of being triggered until falling speed reaches a certain larger value, the safety coefficient is greatly increased, and equipment loss caused by sudden speed reduction is reduced. Arranged safety pins share a part of falling energy, falling speed will be reduced to a certain extent by shearing the safety pins, and then the anti-falling protection capacity is improved further.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator anti-drop safety protection mechanism based on safety gear control. Background technique [0002] The emergence of high-rise buildings has greatly improved the land utilization rate and brought better sightseeing opportunities for people. At the same time, it has enhanced the charm of the city's image and become a display window for urban development. As one of the essential components in high-rise buildings, elevators play an important role. According to incomplete statistics, as of 2015, there are more than one million elevators in service across the country. It can be seen that elevators have become one of the indispensable tools in daily life. The number of elevators is not only increasing day by day, but people's research on elevators is also deepening day by day. In the long-term research and use, people have found that the safety of elevators ha...
