Embodiment

[0019] In this embodiment, a protection system for preventing accidental movement of the car, such as figure 1 As shown, it includes a control board 1 for identifying the state of the elevator car and a protection actuator 2 for locking the elevator according to the instructions of the control board. The signal input terminals of the control board are respectively connected with a door-closed limit switch 5 for detecting whether the car door is fully closed. , Door lock contactor switch for whether the door lock is locked 4, door zone switch for whether the car reaches the door zone 8, door open re-leveling signal switch 6, car door opening action switch 7 in advance, elevator inspection switch 3 and device deactivation switch 9. The signal output terminal of the control board is connected to the protective actuator.

[0020] Such as figure 2 As shown, the protection actuator includes a hanging plate 11 installed on the guide rail 10, a bracket 13 fixed to the upper beam 12...

Abstract

The invention relates to a car accidental movement prevention protecting system. The car accidental movement prevention protecting system solves the problem of accidental movement of a car which leaves a landing due to the facts that a landing door is not locked or a car door is not closed. The car accidental movement prevention protecting system comprises a control panel and a protection executing mechanism; the signal input end of the control panel is connected with a door closing in-position switch, a door lock contactor switch and a door area switch, and the signal output end of the control panel is connected with the protection executing mechanism. The car accidental movement prevention protecting system has the advantages of achieving diversification in protection triggering and improving the safety of avoiding the accidental movement of the car, so that the safety of the car can be protected in advance when the landing door is not locker or the car door is not closed no matter whether the accidental movement of the car is detected or not. The car accidental movement prevention protecting system is significant to protecting equipment safety of an elevator and the human safety of passengers, simple in structure, simple and flexible in action, safe, reliable and high in practicality.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a protection system for preventing accidental movement of a car. Background technique [0002] The protection of the accidental movement of the car is one of the main contents of the research in the elevator industry at present. It is mainly to stop the accidental movement of the car leaving the landing when the landing door is not locked and the car door is not closed. This kind of unexpected movement is Due to the failure of any single component in the elevator drive host or drive control system on which the safe operation of the car depends, it has become one of the important parameters to test the safety performance of the elevator. Many different designs have been proposed for this problem in the prior art. For example, the patent publication number is CN103466407A, which relates to a car accidental movement protection device, including independent door lock contacts, shaf...
