Abstract
The utility model relates to a protection device for elevator overload and in particular relates to a secondary protection device for elevator overload. According to the technical scheme, the secondary protection device consists of a people number collecting device and a data processing system; an elevator door system is controlled by the data processing system; the in-out person number collecting device consists of a plurality of human body detectors which are mounted on an optical screen and are used for judging the quantity of people entering and exiting the elevator; each group of human detectors consists of two distance sensors; and the state of a passenger entering and exiting an elevator cab is judged through the two distance sensors. The secondary protection device provided by utility model has the following beneficial effects: the quantity of persons entering and exiting the elevator can be measured and calculated by the human detectors, and the quantity of persons taking the elevator can be limited, so that the elevator overload is avoided. Particularly, when an elevator weighing instrument has a fault, the security accidents caused by the overload are avoided.
Description
Technical field:
The utility model relates to a kind of elevator overload protection device, particularly a kind of elevator overload second protection device.
Background technology:
At present, the elevator overload protection device is a pith that guarantees elevator safety operation, and general elevator overload protection device adopts the elevator weighing appearance, and it is installed at the bottom of the sedan-chair, realizes the action of overload switch through the amount of compression of car damping.The problem of its existence is: because weighing instrument does not have the mandatory requirement time-based maintenance or changes, cause certain potential safety hazard, in recent years, because the safety misadventure that the elevator overload causes grows in intensity, cause huge threat for elevator ride person's life security.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of elevator overload second protection device is provided, and overload realizes secondary calculating to elevator, avoids the elevator overload.
Its technical scheme is: be made up of turnover number harvester and data processing system; Through data processing system control elevator car door system; Described turnover number harvester is made up of many groups human body detector, organizes human body detector more and is installed on the light curtain, judges the number of turnover elevator; Every group of human body detector is made up of two rang sensors respectively, judges that through two rang sensors the occupant passes in and out the state of car.
Above-mentioned a kind of scheme is: organize on the light curtain of top of gate that human body detector laterally is installed in elevator, every group of human body detector rearranged by horizontal direction by two rang sensors respectively, judges the number of turnover elevator more.
Above-mentioned another kind of scheme is: organize on the light curtain of both sides of gate that human body detector vertically is installed in elevator, every group of human body detector rearranged by horizontal direction by two rang sensors respectively, judges the number of turnover elevator more.
Above-mentioned many groups human body detector adopts three groups.
The beneficial effect of the utility model is: through human body detector the number of turnover elevator is calculated; Can take the number of elevator through restriction; Thereby avoid the elevator overload, when particularly the elevator weighing appearance breaks down, avoid because the safety misadventure that overload causes.
Description of drawings:
Accompanying drawing 1 is the process principle figure of the utility model;
Accompanying drawing 2 is structural representations of a kind of embodiment of the utility model;
Accompanying drawing 3 is structural representations of the another kind of embodiment of the utility model;
Among the last figure: human body detector A, B, C, gate D, light curtain E.
The specific embodiment:
Embodiment 1: combine accompanying drawing 1-2; The utility model is done further to describe: the utility model is made up of turnover number harvester and data processing system; Through data processing system control elevator car door system; Wherein, data processing system is the prior art that those of ordinary skill is known, and no longer details.And described turnover number harvester is made up of three groups of human body detector A, B, C, and three groups of human body detector A, B, C laterally are installed on the light curtain E of top of gate D of elevator, can judge the number of turnover elevator through three groups of human body detector A, B and C; Every group of human body detector arranged to be installed on the light curtain E by horizontal direction by two rang sensors respectively and formed, and judges that through two rang sensors the occupant passes in and out the state of car.
During use; Through human body detector the number of turnover elevator is calculated, specifically: three groups of human body detectors make the number that is used for judging the turnover elevator through cooperatively interacting of rang sensor, and then can limit the number of taking elevator and be no more than 13-15 people; Whether normally move through data processing system control elevator car door system; Thereby avoid the elevator load-carrying to surpass and appraise and decide weight, like this, even when the elevator weighing appearance breaks down; Also can carry out second protection, avoid because the safety misadventure that overload causes through the utility model to elevator.
Embodiment 2: with reference to accompanying drawing 3, other structures of present embodiment are with reference to embodiment 1, and difference is:
Many group human body detectors are made up of three groups of human body detector A, B, C; And vertically be installed on the light curtain E of both sides of gate (D) of elevator; Every group of human body detector arranged to be installed on the light curtain E by horizontal direction by two rang sensors respectively and formed, thereby judges the number of turnover elevator.
During use; Through human body detector the number of turnover elevator is calculated, specifically: three groups of human body detectors make the number that is used for judging the turnover elevator through cooperatively interacting of rang sensor, and then can limit the number of taking elevator and be no more than 13-15 people; Whether normally move through data processing system control elevator car door system; Thereby avoid the elevator load-carrying to surpass and appraise and decide weight, like this, even when the elevator weighing appearance breaks down; Also can carry out second protection, avoid because the safety misadventure that overload causes through the utility model to elevator.
