Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0034] It should be noted that when an element is referred to as being "fixed on", "disposed on", "fixed on" or "installed on" another element, it can be directly on the other element or there can also be an intervening element . When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. Furthermore, when one component is considered to be "fixedly connected" to another component, the two can be fixed in a detachable connection, or in a non-deta...

The invention discloses an elevator system, a maintenance safety device and a driving mechanism. The driving mechanism comprises a driving member and a triggering unit; an installation part is arranged on the driving member and is fixedly connected with a dead bolt of a hoistway door; the driving member comprises a matching body which is for matching with the driving of a latch hook of the hoistway door, and a connecting body; the matching body is fixed to the connecting body; a triggering part which is for matching with the triggering of a safety switch is arranged on the triggering unit; andthe triggering unit is connected with the connecting body and enables the triggering part to move with the driving member. The driving mechanism can match with a lock of the hoistway door, meet the unlocking requirements of the hoistway door, and match with the safety switch to switch an elevator to a safety mode. The maintenance safety device adopts the driving mechanism and can trigger the safety mode of the elevator when the hoistway door is opened, so the safety of elevator pit maintenance is improved. The elevator system adopts the maintenance safety device and can meet the requirementsof elevator pit safety maintenance, so the maintenance of the elevator is safer.
Description
technical field [0001] The invention relates to the technical field of lifting equipment, in particular to an elevator system, an inspection safety device and a transmission mechanism. Background technique [0002] With the continuous development of society, there are more and more high-rise buildings. Elevators, as the most important vertical means of transportation, are more and more widely used in buildings and gradually become an indispensable part of people's lives. [0003] As one of the special equipment, the elevator needs regular maintenance during daily use in order to ensure the safe operation of the elevator. When performing maintenance on the pit or car bottom parts, it is occasionally necessary to make the car go down for maintenance when there are people in the pit. Fully communicate to prevent being squeezed by the descending car. [0004] However, in actual operation, due to insufficient communication or operational errors, it is easy to cause the car to g...
