Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, and more specifically, to a new type of main machine displacement switch. Background Technique

[0002] The main machine displacement switch is an electrical component installed at the bottom of the elevator car and is also an important part of the elevator components.

[0003] After retrieval, the existing driving main machine displacement protection device with the publication number of CN210710302U includes a driving main machine installation base plate, a switch installation frame, a gear and an escalator. A driving main machine is arranged on the driving main machine installation base plate, and a travel bracket is arranged on the driving main machine installation base plate; through the combined action of the driving main machine installation base plate, the driving main machine, the fixing bolts, the reset switch, the travel bracket and the switch installation frame, the travel bracket is installed at the fixing bolts of the driving main machine. When the driving main machine has a displacement, the travel bracket will synchronously generate a displacement amount, thereby triggering the manual reset switch to act, and its action signal is fed back to the escalator or sidewalk control system, and the system issues a stop ladder instruction, and the escalator or sidewalk immediately stops running, avoiding safety hazards such as insufficient chain tension and reverse rotation of the escalator caused by the displacement of the driving main machine, and more effectively ensuring the safety of passengers taking the elevator.

[0004] For common main machine displacement switches, most of them start the switch through direct contact, which is easy to cause wear and has low sensitivity. Therefore, we propose a new type of main machine displacement switch to solve the above existing problems. Content of the Utility Model
