Description

Technical Field

[0001] The embodiments of this utility model belong to the field of wire rope positioning technology, and more specifically, relate to a positioning device for wire rope detection. Background Technology

[0002] As a high-strength, flexible load-bearing component, steel wire rope is widely used in many industrial fields and daily life scenarios, such as mine hoisting, construction, port loading and unloading, and elevator operation, due to its high load-bearing capacity, good toughness, and wide range of applications. During long-term service, steel wire rope will gradually suffer damage such as wire breakage, rust, and diameter reduction due to various factors such as alternating loads, wear, corrosion, and fatigue. If these damages are not detected and treated in time, they may lead to steel wire rope breakage, causing serious safety accidents such as equipment failure and personal injury. Therefore, regular inspection and condition monitoring of steel wire rope is a key link to ensure the safe and stable operation of related equipment.

[0003] Currently, various wire rope testing equipment has emerged in the industry. These equipment mainly use technologies such as magnetic detection and ultrasonic testing to identify the damage to wire ropes and provide a basis for equipment maintenance. However, in terms of core functions, most existing testing equipment focuses on the identification and judgment of damage. They lack effective technical support and mature solutions for locating the specific location of damage on the wire rope. The lack of location function has become an important factor restricting the practicality of testing work.

[0004] The current steel wire rope inspection technology and equipment have the following three disadvantages: (1) It is impossible to accurately locate the specific location of the damage on the steel wire rope, which requires a comprehensive inspection of the steel wire rope during the later maintenance, increasing the difficulty of the work; (2) In order to find the location of the damage as much as possible, multiple repeated inspections are required, and manual inspections are required at the same time during the inspection process, making the overall process cumbersome, time-consuming and labor-intensive; (3) The existing inspection method has high skill requirements for operators, high labor intensity, and is prone to jamming and blocking due to equipment and steel wire rope coordination problems during the inspection process, which affects the smooth progress of the inspection work and brings great inconvenience to the actual operation. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a positioning device for wire rope detection. The self-resetting wheel frame assembly, divided into upper and lower parts, ensures the positioning device's vibration resistance during actual use. The encoder wheel assembly installed at the bottom of the self-resetting wheel frame assembly ensures that the positioning device can move back and forth while clearly indicating the actual distance traveled. The encoder assembly installed on the side of the self-resetting wheel frame assembly transmits the rotation data of the encoder wheel assembly while protecting the wheel axle.

[0006] To achieve the above objectives, this utility model provides a positioning device for steel wire rope detection, comprising: The self-resetting wheel frame assembly includes a connecting seat located at the top of the self-resetting wheel frame assembly, a pin inserted into the bottom two ears of the connecting seat, and a mounting base connected to the outer surface of the pin through the top two ears. The encoder wheel assembly located at the bottom of the self-resetting wheel frame assembly includes a cylindrical encoder roller, an axle inserted into the central through hole of the encoder roller, and a magnetic sensitive element located at the top of the axle.

[0007] Furthermore, the self-resetting wheel frame assembly is divided into upper and lower parts, with the mounting base being the lower part and the connecting seat being the upper part.

[0008] Furthermore, the mounting base and connecting seat can rotate slightly around the pin.

[0009] Furthermore, the magnetic sensing element can rotate synchronously with the encoding roller.

[0010] Furthermore, the coding wheel assembly also includes a spline disposed in the keyway on the side of the wheel axle, bearings disposed on the two ears on the bottom of the mounting base, and a retaining ring connected to the bottom of the outer side of the wheel axle and closely attached to the bearing.

[0011] Furthermore, the spline needs to be inserted into the keyway through hole at the center of the encoding roller.

[0012] Furthermore, the self-resetting wheel frame assembly also includes a reset torsion spring disposed on the outer side of the pin shaft and a bushing disposed on the bottom side lug of the connecting seat.

[0013] Furthermore, the lower part of the reset torsion spring abuts against the mounting base, and the upper part of the reset torsion spring abuts against the connecting seat.

[0014] Furthermore, it also includes an encoder assembly located on the side of the self-resetting wheel frame assembly.

[0015] Furthermore, the encoder assembly includes a protective cover bolted to one side of the mounting base, an encoding chip disposed on one side of the mounting base, and an aviation plug inserted into a circular hole at the top of the side of the protective cover.

[0016] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: 1. The positioning device of this utility model, through the self-resetting wheel frame assembly divided into upper and lower parts, can ensure the vibration resistance of the positioning device during actual use. Through the encoder wheel assembly installed at the bottom of the self-resetting wheel frame assembly, it can ensure that the positioning device can move back and forth while clearly knowing the actual distance traveled by the positioning device. Through the encoder assembly installed on the side of the self-resetting wheel frame assembly, it transmits the rotation data of the encoder wheel assembly while protecting the wheel axle of the encoder wheel assembly.

[0017] 2. The component of this utility model achieves a small-amplitude rotation of the connecting seat and the mounting base by inserting a bushing into the mounting hole on the bottom side ear of the connecting seat and inserting a pin into the bushing. The self-resetting wheel frame assembly can rotate slightly and return to its original position by using the connecting seat as the upper part, the mounting base as the lower part, and the reset torsion spring located between the connecting seat and the mounting base, thereby enhancing the vibration resistance of the self-resetting wheel frame assembly.

[0026] This utility model embodiment provides a positioning device for steel wire rope detection, such as... Figure 1As shown, the device includes an encoder wheel assembly 1, a self-resetting wheel frame assembly 2, and an encoder assembly 3. The self-resetting wheel frame assembly 2 serves as the main structure of the positioning device. It is divided into upper and lower parts, which can rotate relative to each other to a certain extent and return to their original positions, providing a certain degree of vibration resistance. The encoder wheel assembly 1 is installed at the bottom of the self-resetting wheel frame assembly 2 and can rotate freely around the wheel axle 12. The magnetic sensing element 16 on the encoder wheel assembly 1 rotates synchronously with it. The encoder wheel assembly 1 is used to ensure the front of the positioning device... The device moves forward and backward, recording the distance traveled. Then, the encoder assembly 3 is installed on the side of the self-resetting wheel frame assembly 2, with the bottom of the protective cover 31 in the encoder assembly 3 concentric with the encoding roller 11 in the encoding wheel assembly 1. The encoder assembly 3 contains an encoding chip 32, which records the number of rotations of the magnetic sensitive element 16 and transmits the data to the encoding counting software on a remote terminal. The encoding counting software calculates an accurate position signal based on the rotation data transmitted by the magnetic sensitive element 16. The encoder assembly 3 also protects the axle 12 in the encoding wheel assembly 1 from impact damage during actual use. This positioning device, through its self-resetting wheel frame assembly divided into upper and lower parts, ensures the positioning device's vibration resistance during actual use. The encoding wheel assembly installed at the bottom of the self-resetting wheel frame assembly ensures the positioning device can move forward and backward while clearly recording the actual distance traveled. The encoder assembly installed on the side of the self-resetting wheel frame assembly transmits the rotation data of the encoding wheel assembly while protecting the axle of the encoding wheel assembly.

[0027] Specifically, in the self-resetting wheel frame assembly 2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the assembly includes a mounting base 21, a connecting seat 22, a pin 23, a reset torsion spring 24, and bushings 25. The connecting seat 22 is located at the top of the self-resetting wheel frame assembly 2. Mounting holes are provided on the bottom two side ears of the connecting seat 22. Bushings 25 are inserted into the mounting holes on the bottom side ears of the connecting seat 22. The pin 23 is inserted through one side of the bushing 25 and exits through the other side, and is inserted into the bottom two side ears of the connecting seat 22. The reset torsion spring 24 is mounted on the outer surface of the pin 23, located inside the connecting seat 22 and between the two bushings 25. The mounting base 21 has mounting holes on the top two side ears, which are mounted on the outer surface of the pin 23. The self-resetting wheel frame assembly 2 is divided into upper and lower parts. The connecting seat 22 is the upper part, and the mounting base 21 is the lower part. The mounting base 21 and the connecting seat 22 can rotate slightly under the action of the pin 23. The upper part of the reset torsion spring 24 abuts against the connecting seat 22, and the lower part of the reset torsion spring 24 abuts against the mounting base 21. After the mounting base 21 and the connecting seat 22 rotate slightly, they will return to their original positions under the action of the reset torsion spring 24. The rotation and reset of the mounting base 21, the connecting seat 22, and the reset torsion spring 24 enhance the vibration resistance of the positioning device. The bottom two ears of the mounting base 21 are also provided with corresponding mounting holes, and a corresponding screw hole is provided on one side. The component of this utility model achieves a small-amplitude rotation of the connecting seat and the mounting base by inserting a bushing into the mounting hole on the bottom side ear of the connecting seat and inserting a pin into the bushing. The self-resetting wheel frame assembly can rotate slightly and return to its original position by using the connecting seat as the upper part, the mounting base as the lower part, and the reset torsion spring located between the connecting seat and the mounting base, thereby enhancing the vibration resistance of the self-resetting wheel frame assembly.

[0028] Specifically, in the encoding wheel component 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the assembly includes an encoding roller 11, axle 12, spline 13, bearing 14, retaining ring 15, and magnetic sensitive element 16. A keyway is formed on the side of the axle 12, and the spline 13 is installed within this keyway. The magnetic sensitive element 16 is mounted on the top of the axle 12, rotating synchronously with it and recording the number of rotations. A retaining ring 15 is installed on the bottom outer side of the axle 12. The bearing 14 is installed in mounting holes on the bottom ears of the mounting base 21 in the self-resetting wheel frame assembly 2, and the axle 12 is inserted into the bearing 14. In this assembly, the encoding roller 11 is cylindrical, with a through hole and a keyway through hole at its center. The axle 12 is inserted into the through hole at the center of the encoding roller 11, and the spline 13 is engaged in the keyway through hole. With the help of the spline 13, the axle 12 can rotate synchronously with the encoding roller 11. After the encoding roller assembly 1 is installed, the encoding roller 11 can rotate freely under external force, thereby driving the axle 12 to rotate, which in turn drives the magnetic sensitive element 16 to rotate. The retaining ring 15 is tightly attached to the side of the bearing 14 to prevent the axle 12 from becoming loose during rotation. In this assembly, the spline installed in the keyway on the outer side of the axle synchronizes the rotation of the encoding roller with the axle. The retaining ring installed at the bottom of the outer side of the axle prevents the axle from becoming loose during rotation. The magnetic sensitive element installed at the top of the axle records the number of rotations of the encoding roller while it rotates.

[0029] Specifically, in encoder component 3, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the device includes a protective cover 31, an encoding chip 32, and a flight plug 33. The protective cover 31 has a round hole on its top side. The protective cover 31 is bolted to one side of the mounting base 21. The flight plug 33 is inserted into the round hole on the top side of the protective cover 31. The flight plug 33 can be used to connect the encoding chip 32 to external devices such as external power supplies. The encoding chip 32 is mounted on one side of the mounting base 21 and locked in the corresponding screw hole on one side of the mounting base 21. The encoding chip 32 is used to transmit the number of rotations of the encoding roller 11 recorded by the magnetic sensitive element 16 to the encoding counting software of the remote terminal. The protective cover 31 wraps the protruding side of the wheel axle 12 inside to prevent the wheel axle 12 from being damaged by bumps during use.

[0030] In another embodiment of this utility model, an operation method for a positioning device for steel wire rope detection is provided, comprising the following steps: First, observe the position of the self-resetting wheel frame assembly 2 and check whether the mounting base 21 and the connecting seat 22 are intact. Then, confirm that the surface of the encoder roller 11 is free from wear and dents, and that the wheel axle 12 and the bearing 14 are tightly connected without any looseness or jamming. Finally, ensure that the signal transmission line is unobstructed and connect the device power supply.

[0031] First, loosen the fixing bolts on the mounting base 21, then rotate the connecting seat 22 around the pin 23 to a suitable angle so that the coding roller 11 can fully fit with the surface of the steel wire rope to be inspected. Then tighten the fixing bolts to lock the position of the mounting base 21.

[0032] Enter the main control system operation interface of the wire rope testing equipment, and input the relevant basic information of the wire rope to be tested, including parameters such as the diameter and length of the wire rope, in the parameter setting module corresponding to the positioning device.

[0033] When the wire rope detection equipment is started, the coding roller 11 of the positioning device rotates synchronously under the friction of the wire rope. The wheel axle 12 drives the magnetic sensitive element 16 to rotate continuously. The encoder assembly 3 collects the rotation signal of the magnetic sensitive element 16 in real time and converts the signal into an electrical signal to be transmitted to the coding counting software.

[0034] After the testing is completed, first stop the signal acquisition function of the traction device and positioning device of the testing equipment, and then save the complete data of this test in the main control system for later inspection and analysis.

[0035] In summary, this positioning device for wire rope testing achieves automatic positioning of the wire rope to be tested, ensuring that the wire rope passes smoothly without getting stuck or blocked. It has a simple structure, is easy to operate, and can promptly and effectively meet the positioning needs of the testing equipment during the testing process of the wire rope to be tested, thus improving the efficiency of the testing work.

[0036] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
