Abstract
The utility model discloses a kind of safety protection apparatus for elevator; a kind of safety protection apparatus for elevator; comprise the restriction limiting unit of cage operation, receiving element, for detecting the safety sensor of described receiving element; described limiting unit is arranged on the top of car; described safety sensor is arranged on the bottom of described car, and described receiving element is fixed on cage guide.The utility model is by arranging the limiting unit of restriction cage operation at the top of car, cage guide arranges the receiving element for detecting safety sensor, the bottom of car arranges safety sensor, after elevator falls suddenly, the signal transmission that safety sensor sends is to receiving element place, limiting unit can make corresponding reaction, the generation beyond prevention, increases the safety of elevator device.
Description
Technical field
The utility model relates to a kind of lift appliance, is specifically related to a kind of safety protection apparatus for elevator.
Background technology
General conventional elevator is when carrying out car top maintenance parts, the braking of lift car relies on and drives the brake gear of main frame to be checked by main frame traction sheave band-type brake, and by the friction force of traction steel-cable and traction sheave, thus lift car is fixed on certain position of elevator hoistways.If falling unexpectedly appears in elevator, thus lift car cannot be fixed on certain position of elevator hoistways, then can hurt the service personnel carrying out service work at pit, cause safety misadventure.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of safety protection apparatus for elevator, and an extra increase protection system, increases the safety of system.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of safety protection apparatus for elevator; comprise the restriction limiting unit of cage operation, receiving element, for detecting the safety sensor of described receiving element; described limiting unit is arranged on the top of car; described safety sensor is arranged on the bottom of described car, and described receiving element is fixed on cage guide.
Further, described limiting unit comprises switching circuitry.
The beneficial effects of the utility model are:
The utility model is by arranging the limiting unit of restriction cage operation at the top of car, cage guide arranges the receiving element for detecting safety sensor, the bottom of car arranges safety sensor, after elevator falls suddenly, the signal transmission that safety sensor sends is to receiving element place, limiting unit can make corresponding reaction, the generation beyond prevention, increases the safety of elevator device.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
