Description

Elevator door lock detection device

Technical Field

The utility model relates to an elevator lock detects technical field, in particular to elevator lock detection device.

Background

When the elevator door or the car door is closed, the mechanical locking element (such as a lock hook and a latch) is engaged or hooked for 7mm at least, an electric safety device for verifying the locking state of the door lock can be switched on, and the car can normally run. And finding a critical point when the contact of the electric safety device is just contacted, and measuring the length of coincidence between the lock hook and the hook block at the moment to obtain the engagement length of the door lock.

In the detection process, the critical point determination of the contact point of the electric safety device just before contact is crucial, and most of the existing methods are divided into four types, namely: the spark method, the sound method, the test run method and the voltage method are most accurately used.

The basic steps of the voltage method measurement are as follows: selecting a voltage level by using a multimeter, connecting two connecting wires of the multimeter with two electrical contacts of the door lock, wherein the reading of the multimeter is a certain constant value V, slowly closing a locking element, and obtaining a critical point of door lock meshing when the reading of the multimeter is suddenly changed from a V value to a value close to zero; and (4) judging by the method.

For the contact of elevator layer door is greatly multi-purpose be cylindrical male contact cooperation hollow cylindrical female contact, two sense terminals of traditional universal meter are the cylinder electrode, need both hands contact an electrical safety device's contact respectively during the use, it is not very convenient.

In order to solve this problem, improve on traditional universal meter basis, adopt the electricity to press from both sides the formula fixed, and the electricity presss from both sides the formula and detects and prevent to press from both sides the chuck on the contact, it is still comparatively convenient to cylindrical male contact centre gripping, but to hollow cylindrical female contact, hollow cylindrical female contact is sunken shape contact, and the chuck is just inconvenient fixed this moment to if fixed the back by force, can extend the contact position of hollow cylindrical female contact for the common contact, thereby influence and detect the precision.

Therefore, the elevator door lock detection device is provided.
