Abstract

The utility model discloses a kind of safety control system preventing accidental movement of elevator cage, comprise elevator control cabinet, velocity limiter and car stop power element; Velocity limiter is provided with and rotates monitoring means and Signal reception judging unit, rotation monitoring means and elevator control cabinet are all connected to Signal reception judging unit, and Signal reception judging unit is connected to car stop power element; Velocity limiter is also provided with rope sheave brake unit, and the rope sheave of the corresponding velocity limiter of rope sheave brake unit is arranged, and rope sheave and car stop power element link.This utility model gathers elevator safety loop status signal by Signal reception judging unit and cage operation status signal judges, when car accidental movement, send electric signal and carry out the urgent stop of car to car stop power element, thus avoid and judge velocity limiter speed, acceleration/accel and deficiency that displacement produces merely, lift running safety is high.

Description

Prevent the safety control system of accidental movement of elevator cage
Technical field
The utility model relates to elevator technology field, particularly a kind of safety control system preventing accidental movement of elevator cage.
Background technology
Prevailing in China in Recent Years elevator market, with the explosive growth of elevator quantity, has reached more than 3,000,000.But with the increase of quantity, elevator accident quantity also increases thereupon.Especially open the door and slip car Frequent Accidents, consequence is serious, causes social extensive concern.
Analyze elevator and slip car accident, have following reason to cause: brake braking force is abnormal, equilibrium factor is not enough, overload, door lock short circuit, control abnormal etc., wherein controls to be cause elevator to slip the major reason of car accident extremely.Conventional safety control mode judges merely velocity limiter speed, acceleration/accel and displacement, and its two large deficiencies produced are: when 1, elevator door is opened, elevator starts with normal speed, the shielding failure caused; 2, when the normal upper and lower passenger of elevator or handling goods, the normal sedimentation of car, causes protection by mistake.Therefore, based on above-mentioned accident causation and elevator design present situation, develop a kind of more effective car accidental movement safety control system imperative.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of safety control system preventing accidental movement of elevator cage, the urgent stop safety control occurred when surprisingly slipping car of opening the door to realize stopping.
For achieving the above object, the technical solution of the utility model is as follows:
Prevent a safety control system for accidental movement of elevator cage, comprise elevator control cabinet, velocity limiter and car stop power element;
Described velocity limiter is provided with and rotates monitoring means and Signal reception judging unit, described rotation monitoring means and elevator control cabinet are all connected to described Signal reception judging unit, and described Signal reception judging unit is connected to described car stop power element;
Described velocity limiter is also provided with rope sheave brake unit, and the rope sheave of the corresponding described velocity limiter of described rope sheave brake unit is arranged, and described rope sheave and described car stop power element link.
Wherein, when described velocity limiter being provided with described rotation monitoring means and Signal reception judging unit, described car stop power element is wire holder or towing machine.
Wherein, when described velocity limiter being provided with described rotation monitoring means, Signal reception judging unit and rope sheave brake unit, described car stop power element is bidirectional safe brake equipment.
Pass through technique scheme, the safety control system of what the utility model provided prevent accidental movement of elevator cage, elevator safety loop status signal and cage operation status signal is gathered by Signal reception judging unit, judge, when car accidental movement, send electric signal and carry out the urgent stop of car to car stop power element, thus avoid and judge velocity limiter speed, acceleration/accel and deficiency that displacement produces merely, lift running safety is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is a kind of car accidental movement safety control system structural representation being controlled the urgent stop of car by wire holder or towing machine disclosed in the utility model embodiment;
Fig. 2 is a kind of car accidental movement safety control system structural representation being controlled the urgent stop of car by bidirectional safe brake equipment disclosed in the utility model embodiment;
Fig. 3 is the principle of work schematic diagram of a kind of car accidental movement safety control system disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1 and 2, the safety control system of what the utility model provided prevent accidental movement of elevator cage, comprises elevator control cabinet, velocity limiter and car stop power element.
Wherein, with reference to figure 1 and 3, velocity limiter is provided with and rotates monitoring means and Signal reception judging unit, rotation monitoring means and elevator control cabinet are all connected to Signal reception judging unit, Signal reception judging unit is connected to wire holder or towing machine, and its principle of work is:
Velocity limiter increases Signal reception judging unit, elevator safety loop status signal and cage operation status signal is gathered by elevator control cabinet and rotation monitoring means, judge, when car accidental movement, send electric signal to wire holder or towing machine, make towing machine stop or make wire holder action; Wherein, the electromagnet of wire holder when elevator normally runs in flip flop equipment is in "on" position, and when lift car meets accident, velocity limiter sends electric signal and makes the power-off of wire holder electromagnet, wire holder clamping traction steel-cable stop car.
Wherein, with reference to figure 2 and 3, velocity limiter is provided with and rotates monitoring means and Signal reception judging unit, rotation monitoring means and elevator control cabinet are all connected to Signal reception judging unit; Also be provided with rope sheave brake unit, the rope sheave of the corresponding velocity limiter of rope sheave brake unit is arranged, and rope sheave and bidirectional safe brake equipment link, and its principle of work is:
Velocity limiter increases Signal reception judging unit and rope sheave brake unit, elevator safety loop status signal and cage operation status signal is gathered by elevator control cabinet and rotation monitoring means, judge, when car accidental movement, send electric signal to the rope sheave brake unit on velocity limiter, stop governor sheave, thus drive bidirectional safety tongs action, make car stop on guide rail, its final power element is bidirectional safe brake equipment.
The safety control system of what the utility model provided prevent accidental movement of elevator cage, elevator safety loop status signal and cage operation status signal is gathered by Signal reception judging unit, judge, when car accidental movement, send electric signal and carry out the urgent stop of car to car stop power element, thus avoid and judge velocity limiter speed, acceleration/accel and deficiency that displacement produces merely, lift running safety is high.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of above-described embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
