no. 1 example

[0038] Such as figure 1 with 2 As shown, the elevator safety device according to the first embodiment of the present invention includes: a through door lock detection circuit 1 and a monitoring module 7 . The door lock detection circuit 1 through the door includes: normally open contacts and normally closed contacts of at least three relays, and at least four relays located between the front end port T2 of the door lock section and the end port T3 of the door lock section. A door lock short circuit detection point. The monitoring module 7 includes: the coils of the at least three relays and a control unit, the monitoring module 7 controls the pull-in or release state of the coils of the at least three relays and monitors the at least four door lock short-circuit detection points The charged state of the through door lock is detected to detect the short circuit state.

[0039] Preferably, the door lock section includes: front car door lock FC1, rear car door lock BC2, front ...

[0046] The elevator safety device according to the second embodiment of the present invention includes: a through door lock detection circuit 1 and a monitoring module 7 . Such as image 3 As shown, the elevator safety device of the second embodiment also includes: a safety relay board for re-leveling and opening the door in advance, and the safety relay board includes: a door lock short circuit 6 (the sixth circuit shown in the figure) for short circuiting the door lock ). At this time, since the detection of the door lock short-circuit state is performed when the door lock short-circuit circuit 6 is closed, compared with the through-door door lock detection circuit in the first embodiment, the through-door door lock detection circuit in the second embodiment 1 The normally open contact K3.1 of the third relay K3 can be omitted to simplify the circuit. The port T4 is located between the normally closed contact K3.2 of the third relay K3 and the normally closed contact K1.2 ...

[0049] The elevator safety device of the third embodiment of the present invention includes: a through door lock detection circuit 1, a monitoring module 7, and a re-leveling and door opening safety relay board. The through door lock detection circuit 1 in this embodiment can be the through door lock detection circuit in the aforementioned first embodiment or the second embodiment, and the monitoring module 7 is the same as the monitoring module 7 in the aforementioned first embodiment.

[0050] Such as Figure 5 As shown, the re-leveling and early door opening safety relay board in this embodiment not only includes the door lock short circuit 6, but also includes: a safety confirmation circuit 5, which is used to judge whether the elevator can safely perform re-leveling and early door opening operations. Preferably, as Image 6 As shown, the safety confirmation circuit 5 includes: the normally closed contact K6.4 of the sixth relay K6, the normally open contact K5.4 of the f...

Abstract

The invention discloses an elevator safety device and an elevator. The elevator safety device comprises a through door lock detection loop and a monitoring module, wherein the through door lock detection loop comprises normally open contacts and normally closed contacts of at least three relays and at least four door lock short circuit detection points located between a front end port of an elevator safety door lock section and a tail end port of the door lock section; and the monitoring module comprises coils of the at least three relays and a control unit, and the monitoring module controlsthe attraction or release state of the coils of the at least three relays and monitors the charged state of the at least four door lock short circuit detection points to detect the short circuit stateof a through door lock.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to an elevator safety device and an elevator including the elevator safety device. Background technique [0002] With the development of my country's economy and society, high-rise buildings continue to emerge, and elevators are gradually becoming popular. In order to improve the operating efficiency and save the waiting time of people, the elevator generally has the function of opening the door in advance, that is, the door is opened in advance when the car is not completely stopped. At the same time, in order to compensate for the loss of the leveling position caused by the stretching of the traction wire rope caused by the entry and exit of the car after the elevator leveling, the elevator generally has a re-leveling function, that is, the car is moved to the leveling position when the door is opened. The movement of these cars requires temporary short-circuiting ...
