Problems solved by technology
In long-term use, the elevator will inevitably have one or another problem, which brings a lot of inconvenience to the user and even threatens the user's life safety.
For example, when the elevator has a power outage, electrical failure, abnormal operation, etc., once the person taking the elevator is trapped in the elevator, they can only wait for rescue and cannot save themselves
[0003] Some of the elevators in the prior art are also equipped with a power supply backup system, but there is no clutch in the backup system, it is completely dependent on electrical operation, and lacks hardware actions, so that the safety of the elevator cannot be guaranteed, and the cost is relatively high

Embodiment Construction
[0025] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0026] Such as Figure 1-6 The shown backup system transmission mechanism includes a hand crank mechanism 10, a clutch mechanism (not shown) and a chain sprocket assembly 20 arranged between the hand crank mechanism 10 and the clutch mechanism. The chain sprocket assembly 20 includes a driving sprocket 21. The driven sprocket 22 and the chain 23. The hand crank mechanism 10 includes a square shaft 11 and a connecting sleeve 12 slidingly connected with the square shaft 11. One end of the square shaft 11 is provided with a handle 13, and the other end of the square shaft 11 is provided with a limiter. 14, the driving sprocket 21 is arranged on the conne...

The invention discloses a diversion system drive mechanism. The diversion system drive mechanism comprises a hand-cranking mechanism, a clutch mechanism and a chain and sprocket assembly; the hand-cranking mechanism comprises a square shaft and a connecting sleeve; a drive sprocket is arranged on the connecting sleeve; the clutch mechanism comprises a drive spline, a spline housing, a first driving device and a second driving device; a driven sprocket is arranged on an input shaft of the second driving device; during disengaging, the spline housing and the drive spline are arranged in a spacedmanner; during engaging, a handle is pulled outwards, and the square shaft and a stopper are driven to move together relative to the connecting sleeve until the connecting sleeve is located at one side, near the stopper, of the square shaft; the handle is turned so as to drive the square shaft, the connecting sleeve and the drive sprocket to rotate, and then, the driven sprocket and the spline housing are driven to rotate; meanwhile, the spline housing moves to the drive spline under the acting force of the first driving device until the spline housing and the drive spline cooperate. The diversion system drive mechanism disclosed by the invention not only is simple and reliable in structure and relatively low in cost but also is relatively high in stability and safety.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a transmission mechanism of an alternate landing system. Background technique [0002] Nowadays, elevators are inseparable from our life, and people's travel and work are inseparable from elevators. In long-term use, the elevator will inevitably have one or another problem, which brings a lot of inconvenience to the user, and even threatens the user's life safety. For example, when the elevator has power failure, electrical failure, abnormal operation, etc., once the person taking the elevator is trapped in the elevator, they can only wait for rescue and cannot save themselves. [0003] Some of the elevators in the prior art are also equipped with a power supply backup system, but there is no clutch in the backup system, which relies entirely on electrical operation and lacks hardware actions, so that the safety of the elevator cannot be guaranteed, and the cost is relatively ...
