Technical Field

[0001] The utility model relates to the technical field of traction sheave detection, in particular to a device for detecting the wear of a wheel groove of an elevator traction sheave. Background Art

[0002] An elevator traction sheave groove wear detection device is a device specifically used to detect the degree of wear of an elevator traction sheave groove. After searching, the Chinese patent authorization number CN220844989U discloses an elevator traction sheave wear detection device. Although the wear detection process of the traction sheave does not require the rotation of the traction sheave, which simplifies the steps of replacing the traction sheave, saves time and effort, and improves the efficiency of traction sheave wear detection, the detection device uses a contact method to detect the wear of the traction sheave groove, which causes the contact part with the traction sheave groove to be affected by the wear of the traction sheave rotation for a long time, thereby affecting the measurement accuracy. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides an elevator traction sheave groove wear detection device, which solves the problem proposed in the background technology that the existing device uses a contact method to detect the wear of the traction sheave groove during detection, resulting in long-term wear of the contact part with the traction sheave groove, which in turn affects the measurement accuracy.

By setting multiple sliding seats and the sliding seats sliding on the outside of the sliding rod, the sliding seats can adjust the position of the detection mechanism according to the width of the wheel groove.

[0016] Preferably, an adjusting bolt is provided on one side of the sliding seat, one end of the adjusting bolt is connected to the outer wall surface of the sliding rod, and the outer wall of the adjusting bolt is threadedly connected to the inner surface of the sliding seat. When the sliding seat slides outside the sliding rod, the side of the adjusting bolt is rotated so that one end of the adjusting bolt can be against the surface of the sliding rod, so that the sliding seat can be fixed. The number of sliding seats is adapted to the number of infrared ranging mechanisms.

[0017] Preferably, the infrared ranging mechanism includes an infrared transmitter installed on one end of the top of the sliding seat, an infrared receiver is provided on one side of the infrared transmitter, the bottom of the infrared receiver is embedded in the top of the support block, and the support block is welded to one side of the sliding seat, wherein the infrared transmitter is used to transmit infrared light signals, using an infrared light emitting diode (LED) or a laser diode, and the infrared receiver is used to receive the reflected infrared light signals, using a photosensitive diode or a photomultiplier tube, and is electrically connected to the microprocessor inside the controller for calculating the distance, usually based on the time difference method or the phase method.

[0021] 1. This elevator traction sheave groove wear detection device controls the electromagnet's circuit switch through a controller to achieve adsorption and release of the metal limit block. When detecting groove wear, the controller disconnects the electromagnet's power supply, causing the electromagnet to lose its magnetism. The limit block detaches under the action of the spring, pushing the lifting rod and the push rod upward. The steel ball on the top of the push rod contacts the groove surface. As the degree of wear varies, the push rod moves upward accordingly. When the wear reaches a certain level, the lifting rod triggers a touch switch, which feeds back a signal to the controller for real-time reminders. The design of the tester allows it to intermittently contact the groove, only contacting the groove during testing and remaining separated from the groove under normal conditions, effectively reducing mutual wear and improving detection accuracy.

[0022] 2. This elevator sheave groove wear detection device uses an infrared transmitter to emit infrared light of a specific wavelength. When this light strikes the surface of the elevator traction sheave, it produces varying degrees of reflection depending on the wear of the groove. An infrared receiver captures this reflected infrared light and transmits the signal to a controller. The controller's internal processor analyzes the reflected signal to identify groove surface wear, thereby assisting in detecting groove wear.

[0023] The utility model solves the problem that the existing device adopts a contact method to detect the wear of the traction sheave groove during detection, which causes the contact part with the traction sheave groove to be worn for a long time, thereby affecting the measurement accuracy.

The outer wall of the top rod 801 is glued to the lifting rod 902. A steel ball is embedded in the bottom of the top rod 801. The circuit switch of the electromagnet 803 is controlled by the controller. When it is necessary to detect the wear of the wheel groove, the power supply of the electromagnet 803 is disconnected, so that the electromagnet 803 loses its magnetism, thereby making the metal limit Block 802 is separated from the adsorption of electromagnet 803, and then the lifting rod 902 is pushed by spring 903, and then the lifting rod 902 can push the top rod 801 to move upward, and the steel ball on the top of the top rod 801 can slide in contact with the surface of the wheel groove.

The detector contacts the wheel groove intermittently and only contacts the wheel groove when in use. It remains separated from the wheel groove under normal conditions, thereby greatly reducing the mutual wear between the detector and the wheel groove and improving the accuracy of detection.
