Elevator turning buffer device

Abstract

The invention provides an elevator turning buffer device aiming at the disadvantages of inconvenient use and poor structural strength of elevator buffers suitable for shallow pits in the prior art, which belongs to the technical field of elevators. The elevator turning buffer device includes a supporting base and a turning base; the upper end of the supporting base is fixed with a main buffer; theupper end of the turning base is fixed with an auxiliary buffer; the supporting base and the turning base are connected in a hinged manner, and the turning base can be turned around a hinge joint andswitched between a combined state and an open state; the lower end of the turning base is provided with a groove; when the turning base is in the combined state, the turning base is covered on the upper end of the supporting base, and the main buffer is located in the groove; when the turning base is in the open state, the auxiliary buffer on the turning base is arranged downward and the turningbase is lower than the main buffer; and a driving mechanism for driving the turning base to turn around the hinge joint is arranged between the supporting base and the turning base. The elevator turning buffer device has an adjustable height, is suitable for shallow pits, can facilitate the inspection and repair of workers, and can improve the safety performance.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator folding buffer device. Background technique [0002] GB7588-2003 "Safety Code for Elevator Manufacturing and Installation" stipulates that when the car is completely pressed on the buffer, there must be a space of 0.5m×0.6m×1m under the lowest part of the car, which is just the smallest space that a person can hide. space, so this is a safe and secure space for personnel entering the pit. The total height of the buffer that meets the above requirements is above 800mm, and the depth of the pit of the elevator shaft is above 1450mm. [0003] In the case where elevators are prevalent in old buildings, underground pipelines and foundations are complicated, and large machinery is difficult to excavate at the well site, in order to avoid the interference of the foundation, reduce the difficulty of excavating the bottom pit, and reduce the excavation workload ...

Problems solved by technology

[0003] In the case where elevators are prevalent in old buildings, underground pipelines and foundations are complicated, and large machinery is difficult to excavate at the well site, in order to avoid the interference of the foundation, reduce the difficulty of excavating the bottom pit, and reduce the excavation workload , it is imperative to reduce the depth of the elevator pit, but when the depth of the pit is too small to meet the above requirements, use a general-purpose elevator buffer. When the safety space for inspection of the pit is satisfied, the car will not be able to operate due to the limit of the buffer height. On ground floor leveling, i.e. common elevator buffers are not suitable for elevators with shallow pits

In order to solve this problem, an invention patent with the publication number CN200985232 is provided in the prior art, and the name is called a reversible elevator buffer. The device is provided with two buffer bodies of different heights. Set vertically, place the buffer body with higher height horizontally, switch to the buffer body with higher height when maintenance is required, that is, turn over the two buffer bodies at the same time, and set the buffer body with higher height vertically, and the buffer body with lower height The buffer body is installed horizontally. The turning process requires the staff to enter the elevator pit first before operating and fixing it with positioning pins. Body or bracket for support, the support structure strength is poor
