Abstract
The invention discloses a hand pinching prevention system of an elevator. The system comprises the following steps: the door of the elevator opens; normally-closed contact switches are judged to be turned on or not; the elevator loses the door-opening power; T-second timed waiting is started; whether T seconds is up is judged; whether the normally-closed contact switches are turned off is judged; the door of the elevator opens normally; and the like. According to the hand pinching prevention system of the elevator, an accident that the elevator pinches hands can be effectively prevented; a plurality of the normally-closed contact switches at different positions are in series connection in a control circuit, that is, normally-closed contact door opening is arranged at all positions where fingers can be pinched; and during the period of waiting judging, the movement of the elevator door stops or the door works oppositely, so that secondary injury can be avoided. The hand pinching prevention system of the elevator is high in applicability and excellent in stability and increase the security coefficient of elevator use.
Description
Technical field
The invention belongs to a kind of incidental injury prevention system, be specifically related to a kind of elevator finger system.
Background technology
The vertical conveyor of elevator to be a kind of with electrical motor be power, is equipped with box like gondola, takes advantage of people or carrying goods for tier building.Serve the fixed type lifting equipment of regulation floor.Vertical lift elevator has a car, operates in the vertical or leaning angle of at least two row and is less than between the rigid guideway of 15 °.Car size and version are convenient to passenger and are come in and gone out or handling goods.Elevator can divide slower elevators (below 1 meter per second), express lift (1 ~ 2 meter per second) and express elevator (more than 2 meter per seconds) by speed.
Along with elevator applications place is increasingly extensive, the elevator of glass door (gate, Room door) is adopted also to increase gradually.Child usually can be attached on glass door of elevator and sees the things that elevator is inside and outside by handle, and child's hand is comparatively thin, and be easily drawn in crack by glass door during enabling and cause injury, this type of accident also often has generation.
Summary of the invention
The present invention proposes for solving prior art Problems existing, its objective is and provides a kind of elevator finger system.
Technical scheme of the present invention is: a kind of elevator finger system, comprises the following steps:
(I) door-opened elevator;
Whether (II) normally closed contact switch is opened, if normally closed contact switch opens performs step (III), if normally closed contact switch is not opened, performs step (VII);
(III) elevator loses enabling power;
(IV) enters T timing second and waits for;
(V) judges whether T timing second arrives, if do not arrive T to perform step (IV) second, if arrive T second, performs step (VI);
(VI) judges whether normally closed contact switch closes, if normally closed contact switch cuts out perform step (VII), if normally closed contact switch does not cut out perform step (III);
(VII) elevator normal door.
T in step (IV), step (V) is 1,1.5,2.
Normally closed contact switch in step (II), step (VI) is one in the gate antetheca normally closed contact switch be arranged in gate, gate operation wall normally closed contact switch.
Normally closed contact switch in step (II), step (VI) is one in the door pocket left normally closed contact switch be arranged on each floor door pocket, the right normally closed contact switch of door pocket.
Normally closed contact switch in step (II), step (VI) is vestibule latc switch.
The right normally closed contact switch series connection of described gate antetheca normally closed contact switch, gate operation wall normally closed contact switch, door pocket left normally closed contact switch, door pocket in the controls.
The present invention can prevent the appearance of elevator tong accident by actv., to connect in control circuit the normally closed contact switch of each position multiple, namely point each position that may crush and be provided with normally closed contact enabling, judging waiting time, the action stopping of elevator door or inverted running can avoid secondary injury, applicability of the present invention is strong, good stability, improves the safety factor that elevator uses.

Detailed description of the invention
Below, with reference to drawings and Examples, the present invention is described in detail:
As shown in Figure 1, 2, a kind of elevator finger system, comprises the following steps:
(I) door-opened elevator (S1).
Whether (II) normally closed contact switch is opened, if normally closed contact switch opens performs step (III), if normally closed contact switch is not opened, performs step (VII) (S2).
(III) elevator loses enabling power (S3).
(IV) enters T timing second and waits for (S4).
(V) judges whether T timing second arrives, if do not arrive T to perform step (IV) second, if arrive T second, performs step (VI) (S5).
(VI) judges whether normally closed contact switch closes, if normally closed contact switch cuts out perform step (VII), if normally closed contact switch does not cut out perform step (III) (S6).
(VII) elevator normal door (S7).
T in step (IV), step (V) is 1,1.5,2.
Normally closed contact switch in step (II), step (VI) is one in the gate antetheca normally closed contact switch 1 be arranged in gate, gate operation wall normally closed contact switch 2.
Normally closed contact switch in step (II), step (VI) is one in the door pocket left normally closed contact switch 3 be arranged on each floor door pocket, the right normally closed contact switch 4 of door pocket.
Normally closed contact switch in step (II), step (VI) is vestibule latc switch.
Described gate antetheca normally closed contact switch 1, gate operation wall normally closed contact switch 2, door pocket left normally closed contact switch 3, the right normally closed contact switch 4 of door pocket are connected in the controls.
Described gate antetheca normally closed contact switch 1 is connected with the pressure sensitivity attaching parts of the activity that gate antetheca is arranged, if finger or other positions of health extrude the pressure sensitivity attaching parts on gate antetheca, gate antetheca normally closed contact switch 1 is opened.
Described gate operation wall normally closed contact switch 2 is connected with the pressure sensitivity attaching parts of the activity that gate operation wall is arranged, if finger or other positions of health extrude the pressure sensitivity attaching parts on gate operation wall, gate operation wall normally closed contact switch 2 is opened.
The left normally closed contact switch 3 of described door pocket is connected with the pressure sensitivity attaching parts of the activity that door pocket left side wall is arranged, if finger or other positions of health extrude the pressure sensitivity attaching parts on door pocket left side wall, the left normally closed contact switch 3 of door pocket is opened.
The right normally closed contact switch 4 of described door pocket is connected with the pressure sensitivity attaching parts of the activity that door pocket right side wall is arranged, if finger or other positions of health extrude the pressure sensitivity attaching parts on door pocket right side wall, the right normally closed contact switch 4 of door pocket is opened.
When T wait time second of step (IV), elevator door opens the door and stops or inverted running, avoids finger to be squeezed.
The present invention can prevent the appearance of elevator tong accident by actv., to connect in control circuit the normally closed contact switch of each position multiple, namely point each position that may crush and be provided with normally closed contact enabling, judging waiting time, the action stopping of elevator door or inverted running can avoid secondary injury, applicability of the present invention is strong, good stability, improves the safety factor that elevator uses.
