Description

Mechanical stopping device for villa elevator

Technical Field

The utility model belongs to the technical field of the elevator, concretely relates to machinery stop device that villa elevator was used.

Background

The villa elevator is essentially an elevator for single-family residences, and because the number of floors of the villa is relatively limited, when the elevator is matched with the villa elevator, the height of a lift car shaft is relatively limited, and the elevator is usually provided without a machine room (the elevator is conventionally called as the elevator without the machine room in the industry). The main machine of the elevator without the machine room is mostly placed at the pit of the hoistway, the control cabinet generally adopts a wall-hanging mode, the space and the cost of the building can be saved by the arrangement mode, convenience is provided for overhauling and maintenance, and the appearance effect of the building is improved.

As is known in the art, in order to ensure the normal and safe operation of a villa elevator, the necessary inspections, such as traction components, braking components, etc., need to be performed by professional attendants entering the hoistway pit periodically or aperiodically. Since the space of the hoistway pit is limited, if the inspection and maintenance personnel in the hoistway pit are in an operating state, the personal safety of the inspection and maintenance personnel can be endangered without doubt as soon as the elevator car abnormally slides down, namely abnormally slides down. Therefore, elevator manufacturers usually have corresponding safety safeguards, such as the above-mentioned mechanical stopping device, in consideration of maintenance safety factors during actual use, and for this purpose, it can also be seen in the published chinese patent literature, for example, CN201598082U recommends "a machine room free elevator car stopping device" using the structure form of telescopic rod to prevent accidental movement of the car, and this patent uses the car roof as an elevator maintenance platform, so many inconveniences are generated during actual use. Typical "elevator maintenance protection devices" as provided in CN102001563A, will be understood from a reading of paragraphs 0004 to 0007 and paragraph 0011 of the specification of this patent: because the elevator needs to be assembled before use and reasonably disassembled after use, and the elevator needs to be stored in a pit or other positions of the elevator without influencing the normal lifting of the elevator after disassembly, certain time is needed before and after use, and the elevator is inconvenient. More typically, "a stopping device for a car of an elevator without a machine room and a working method thereof" introduced in CN102275792B, which patent specifies the disadvantages of the aforementioned CN102001563A in paragraph 0002 of the specification, and which patent arranges the stopping device on the inner wall of the shaft 2-2.5 meters below the inner wall of the shaft from the bottom of the pit to achieve the purpose of ensuring that a sufficient pit safety space is left in case of an accident during maintenance and that the relevant parts of the elevator are not damaged. However, the aforesaid CN102275792B has the following disadvantages: firstly, the civil engineering work is heavy due to the need to deepen the shaft pit significantly and to a deepened extent, for example, 0.5m beyond on the basis of 2m as a shelter, and finally the overall cost of loading the elevator increases, and moreover, since the car glide is often instantaneous and not sudden with a precursor, it is still dangerous for the unprepared maintenance personnel who are in operation; secondly, because the mounting seat, the pin shaft, the braking plate and the braking switches from one to three, namely the first to third braking switches, of the structural system of the braking device serve for overhauling a circuit, the braking device does not have supporting capacity or supporting function when the car slides downwards due to the fact that the car is prevented from danger caused by the falling of the car by a deepened pit; thirdly, although deepening the pit of the hoistway can play a desirable role in protecting the safety of the maintainer, safety hazards are accompanied in case any one of the numerous braking switches of the structural system of the braking device fails or otherwise causes the elevator to slide down abnormally, for example, psychological panic of the maintainer in the pit can be caused in case of the pit (also called as the "pit"), and the like.
