Description
Technical Field
[0001] This utility model belongs to the field of wear detection technology, and in particular relates to mechanical measuring tools for detecting the wear of elevator wire ropes. Background Technology
[0002] Elevator wire ropes are high-strength, flexible components used to connect the elevator car, counterweight, and traction machine, bearing the load and transmission functions during elevator operation. They are made of multiple twisted steel wires and must possess extremely high strength and toughness to ensure safe elevator operation. Mechanical measuring tools are used to detect wear because they can accurately measure parameters such as changes in wire rope diameter and dimensional reduction after wear of the surface wires, directly reflecting the degree of wear. This method is simple to operate, provides accurate data, and can effectively determine whether the wire rope's strength has decreased due to wear, thereby timely assessing its safety status and preventing elevator operation risks caused by excessive wire rope wear.
[0003] However, existing mechanical measuring tools for wear measurement are not easy to adjust the grip spacing according to the actual needs of the inspector during use, which reduces the inspector's comfort and adaptability and affects the efficiency of the inspector's work.

[0027] A specific application of this embodiment is as follows: During use, rotating the handle 225 causes the worm gear 224 to rotate counterclockwise. The worm gear 224, through the turbine 223, drives the bidirectional threaded rod 221 to rotate counterclockwise. This causes the bidirectional threaded rod 221 to cause the two fixed plates 213 to slide on the slide rod 222 and move away from each other. Simultaneously, the two fixed plates 213, through their respective support rods 214, cause their corresponding grips 215 to move away from each other. Through the parallel design of several worm gears 224, bidirectional threaded rods 221, and slide rods 222, the two grips are ensured to move away from each other. Move handle 215 smoothly, and through the reverse operation process described above, bring the two handles 215 closer together. The distance between the two handles 215 can then be adjusted according to the inspector's needs. Start motor 321, which drives shaft 322 to rotate. Shaft 322, through connecting plate 312, drives circular ring 314 to rotate. Circular ring 314 slides within circular groove 313 on support plate 311. The interaction between circular groove 313 and circular ring 314 ensures smooth rotation of connecting plate 312. At this time, connecting plate 312 passes through a rectangular... The bracket 211 moves the two handles 215, thereby adjusting their direction. After adjustment, the wire rope detector 111 is activated. The wire rope detector 111 in this device is a TCK.W wire rope detector. Its working principle is as follows: a weak magnetic field is applied to the wire rope using a weak magnetic loading device, so that the ferromagnetic material of the wire rope establishes a stable and detectable magnetic loading state. A main magnetic field Hz is generated inside, and a main leakage magnetic field Hz1 is generated on the surface. Subsequently, a high-sensitivity weak magnetic sensor extracts the volume element damage of the wire rope based on the principle of spatial magnetic field vector synthesis. The magnetic potential difference information generated by the injury is correlated with a given weak electromagnetic field Bx to derive the magnetic field By. The magnetic balance element converts the change of By into an electrical signal. Then, the data acquisition and conversion device converts and stores the collected information according to a specific mathematical model and data format, and transmits it to the host system processing center via wireless communication. Finally, the mathematical model in the software of the system terminal main control device performs a comprehensive analysis of the data. Based on the change of the magnetic field vector situation, it accurately locates, qualitatively and quantitatively identifies various defects such as broken wires, wear, and corrosion inside and outside the wire rope, thereby detecting the wire rope.
