Lifting and pulling linkage device of car top type safety gear

Abstract

The invention provides a safety gear lifting linkage device arranged on a car roof. The safety gear lifting linkage device is fixed to the car roof and comprises a rotary shaft, a rotary shaft fixing plate, torsion springs, a safety switch switching device, safety gears, safety gear lifting handles, a governor rope lifting handle and a car anti-shaking device. The safety gear lifting linkage device arranged on the car roof is a safety protection device, and when an elevator works abnormally and descends excessively quickly, in order to protect safety of people and materials, the two safety gears installed on straight beams on the two sides of a lift car immediately and simultaneously brake, so that the lift car is stopped on guide rails on the two sides of the lift car. The safety gear lifting linkage device is simple in structural design and convenient to install; compared with a device installed on an upper beam traditionally, the height of the governor rope lifting handle is reduced, and therefore, the aim of lowering a top space is achieved.

Description

technical field [0001] The invention relates to an elevator safety mechanism, in particular to a safety gear lifting linkage mechanism for a machine room-less villa ladder. Background technique [0002] The wells of villa elevators are mostly machine-room-less structures. Machine-room-less elevators have the characteristics of compact structure and exquisite layout. Machine-room-less villa elevators are more delicate and compact, and the wells have different shapes. Change. Since the bottom pit depth and top floor height requirements of villa ladders are smaller than those of passenger elevators, the bottom pit is as small as 300mm or even smaller; the top floor height is as short as 2800mm or even lower. In this case, it is necessary to design a more reasonable and compact elevator. Structures and components to increase space utilization, and even some components that should have been traditionally located at the lower part of the car or at the top of the car have to be mo...

Problems solved by technology

[0005] The safety gear lifting linkage device placed on the lower beam also occupies the space of the pit. Generally, if there is enough space in the pit, there is no problem in placing it on the lower beam. However, when the depth of the pit is small enough, it can be placed in The lower beam is not suitable, because first of all, the safety distance between it and the pit is not enough, and the tensioner device often interferes with the safety gear lifting device

Secondly, it uses the lower beam as the carrier. When the pit is small enough, some villa ladders cancel the lower beam or make the lower beam into an integrated structure with the car bottom. At this time, the safety gear lifting device can no longer be placed on the On the non-existing lower beam under the car floor
