Description

Technical Field

[0001] The utility model belongs to the technical field related to elevators, and in particular relates to a device based on a shaft signal system for detecting absolute positions outside a shaft. Background Art

[0002] Absolute position hoistway signal systems are increasingly being used in elevators. They provide real-time, high-precision measurements of the elevator car's absolute position, ensuring no loss of position after a power outage. They are quick to install and debug, and facilitate optimization of hoistway layout, improving hoistway space utilization.

[0003] With the increasing use of absolute position shaft signals, component failure and damage are inevitable during the operation of the elevator. If the traditional component replacement is used, after the elevator is running, the steel belt or shaft encoder fails, it needs to be removed and replaced, which wastes time and resources.

[0017] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0018] Example 1:

[0019] like Figure 1 As shown, a device based on a shaft signal system for detecting absolute position outside the shaft includes a frame 1, a power mechanism, a pulley assembly and a shaft encoder 2. The pulley assembly includes an active pulley 31 and a passive pulley 32. The two ends of the active pulley 31 and the passive pulley 32 are respectively rotatably connected to the frame 1 through bearing seats. The power mechanism drives the active pulley 31 to drive the passive pulley 32 to rotate. A steel belt 4 is wound between the active pulley 31 and the passive pulley 32. The steel belt 4 penetrates the sensing end of the shaft encoder 2. The shaft encoder 2 is fixed to the corresponding position of the frame 1 for detection sensing. A whole steel belt 4 is wound around the active pulley 31 and the passive pulley 32. Several sensing points on the steel belt 4 are sensed by the shaft encoder, and the control system performs corresponding measurement and display according to the signal.

[0020] Specifically, the power mechanism includes a power motor 51 and a first transmission system 52. The power motor 51 is connected to the active pulley 31 through the first transmission system 52. A second transmission system 33 is provided between the active pulley 31 and the passive pulley 32. The first transmission system 52 is a belt transmission system, and the second transmission system 33 is a synchronous belt transmission system.

[0021] In some embodiments, the active pulley 31 and the passive pulley 32 are both multi-groove pulleys, and the steel belt 4 is wound around the two for circular transmission. Since the steel belt 4 may be very long, the use of multi-groove pulleys can greatly reduce the space occupied by the device.

[0022] In some embodiments, a speed measuring component 6 is included for collecting the running speed. The speed measuring component 6 is an encoder connected to the active pulley 31. The encoder is in frictional contact with the active pulley 31, and the running speed is measured by the rope ratio and fed back to the control system.

[0023] The working principle of the utility model is as follows: the pulley assembly is driven by the power mechanism, thereby driving the steel belt 4 to move normally, and the shaft encoder 2 is used to detect whether the steel belt is normal or damaged, and to simulate the function, collect relevant data and provide it to the elevator main board, so as to achieve the purpose of fast running of the elevator.

[0024] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
