Description

Technical Field

[0001] This utility model relates to the technical field of elevator traction sheave detection devices, specifically, to an elevator traction sheave wear detection device. Background Technology

[0002] In elevator systems, the traction sheave is a core transmission component. Its grooves directly contact the wire ropes, relying on friction to propel the car up and down. Over long-term operation, the surface of the grooves will wear down due to friction. When the wear exceeds a safe threshold, it can lead to problems such as wire rope slippage, uneven tension, or even breakage, posing a serious threat to elevator safety.

[0003] Currently, traction sheave wear inspection mainly relies on manual, periodic checks. Inspectors need to use tools such as vernier calipers to measure parameters such as the depth and width of the sheave grooves. This manual inspection method is not only inefficient and labor-intensive, but may also lead to the failure to detect faults in a timely manner due to delayed inspections. Although some automated inspection devices have emerged in existing technologies, these devices often can only inspect traction sheaves in a static or running state, resulting in low applicability.

[0004] Therefore, how to provide a detection device that can detect traction wheels in both static and running states is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an elevator traction sheave wear detection device, which solves the technical problem that existing detection devices can only detect traction sheaves in a static or running state, resulting in low applicability.

[0006] According to one aspect, at least one embodiment of the present invention provides an elevator traction sheave wear detection device for detecting the wear condition of the sheave groove, comprising:

[0007] Mounting rack;

[0008] The limiting wheel set has at least two sets, and the limiting wheel set is mounted on the mounting frame for rotatably connecting the mounting frame to the traction sheave;

[0009] The detector is configured to correspond to the outer circumferential surface of the traction sheave when the mounting bracket is connected to the traction sheave. The detector includes a sensing unit and an elastic detection element. One end of the elastic detection element is fixedly connected to the mounting bracket, and the other end elastically abuts against the inner sidewall of the wheel groove. The sensing unit is used to measure the magnitude of the elastic deformation of the elastic detection element.

[0010] Optionally, the number of detectors is several, and the elastic detection element of each detector corresponds one-to-one with the groove of the traction sheave.

[0014] Optionally, the mounting bracket may further include a limiting block connected to the longitudinal rod frame, the limiting block being connected to the housing frame of the drive unit that drives the traction sheave to rotate.

[0015] Optionally, the limit wheel assembly includes two wheels and a mounting assembly;

[0016] The two rollers are respectively used to fit against the inner and outer circumferential surfaces of the traction sheave to clamp the sidewall of the traction sheave;

[0017] The mounting assembly is movably connected to the mounting bracket, both of the wheels are connected to the mounting assembly, and the mounting assembly is capable of adjusting the distance between the two wheels.

[0018] Optionally, the installation components include:

[0019] An adjusting linkage and two sliding blocks, the two sliding blocks being respectively connected to the two rotating wheels, and both sliding blocks being movably connected to the longitudinal rod frame;

[0020] Both sliding blocks are movably connected to the adjusting rod and fixed to the adjusting rod by fasteners.

[0021] Optionally, a retaining ring is provided on the end face of the traction wheel near the longitudinal rod frame, and the retaining ring can fit against the end face of the traction wheel to limit the movement of the traction wheel.

[0022] Optionally, the mounting bracket further includes a mounting plate connected to the end of the longitudinal frame away from the transverse frame. The mounting plate is provided with an adjusting handle, the movable end of which is connected to the limiting pressure block. The adjusting handle is used to adjust the pressure of the limiting pressure block on the housing frame of the driver.

[0023] Optionally, a display is provided on the longitudinal frame, and the display is electrically connected to the detector.

[0024] Optionally, a ball bearing is embedded on the movable end of the elastic sensing element.

[0025] The beneficial effects of the embodiments of this utility model are as follows:

[0026] In this invention, when the traction sheave is stationary, the mounting bracket can slide and rotate one revolution along the outer circumferential wall of the traction sheave through the rolling engagement of the limiting wheel assembly with the circumferential surface of the traction sheave, thus completing the detection of the wheel groove of the traction sheave in the stationary state. When the traction sheave is rotating, it is only necessary to install the limiting wheel assembly on the traction sheave and then fix the mounting bracket to the ground or the housing of the traction sheave driver, so that the detector can complete the detection of the traction sheave in the rotating state. This detection device can adapt to the detection needs of both stationary and rotating traction sheaves, overcoming the problem of poor applicability of existing automated detection devices. By measuring the elastic deformation of the elastic detection element through the sensing unit and transmitting it to the detector, the automated detection of the wear condition of the traction sheave wheel groove is realized. Compared with manual inspection, it greatly improves the detection efficiency, reduces labor intensity, and can detect wheel groove wear problems in a timely manner, ensuring the safe operation of the elevator.

[0043] like Figures 1-8 The diagram illustrates an elevator traction sheave wear detection device according to an embodiment of the present invention, used to detect the wear condition of the groove 101 of the traction sheave 1. The detection device includes a mounting frame 2, a limiting wheel assembly 3, and a detector 4. The mounting frame 2 is arranged radially along the traction sheave 1 and positioned on the outer side of any end face of the traction sheave 1. The limiting wheel assembly 3 is slidably mounted on the mounting frame 2 and includes at least two rotating wheels 301 that contact the peripheral wall of the traction sheave 1. The detector 4 corresponds to the outer peripheral surface of the traction sheave 1. The detector 4 includes a sensing unit 41 and an elastic detection element 42. One end of the elastic detection element 42 is fixedly connected to the mounting frame 2, and the other end elastically abuts against the inner wall of the groove 101. The sensing unit 41 is used to measure the magnitude of the elastic deformation of the elastic detection element 42.

[0044] It should be noted that, due to its inherent elastic properties, the elastic detection element 42 always remains in contact with the inner wall of the wheel groove 101. When wear occurs in the wheel groove 101, causing a change in the position of the inner wall, the elastic detection element 42 will undergo corresponding elastic deformation. The deeper the wear in the wheel groove 101, the more the inner wall of the wheel groove 101 shifts towards the center of the traction sheave 1, and the greater the deformation of the elastic detection element 42. The sensing unit 41 monitors this deformation of the elastic detection element 42 in real time, converting the deformation magnitude into quantifiable electrical signals or displacement data, thereby accurately reflecting the amount of wear in the wheel groove 101 and achieving dynamic detection of the wear condition of the wheel groove 101 of the traction sheave 1.

[0045] During testing, such as Figure 1 As shown, when the traction sheave 1 is stationary, the mounting frame 2 can rotate one revolution around the axis of the traction sheave 1 through the rolling engagement of the rotating wheel 301 with the circumferential surface of the traction sheave 1, and drive the detector 4 to move one revolution along the outer circumferential surface of the traction sheave 1 to complete the detection of the wheel groove 101 of the traction sheave 1 in the stationary state. For example, when the traction sheave 1 is in a state that has been removed from the elevator drive, or when the traction sheave 1 is in a state that has just been manufactured, in order to fully detect the wheel groove 101 of the traction sheave 1, the traction sheave 1 can be placed flat on the ground or on a tooling table, and then the two rotating wheels 301 of the limiting wheel set 3 are respectively attached to the inner and outer circumferential surfaces of the traction sheave 1, clamping the traction sheave 1 from both sides. At least two limiting wheel sets 3 are circumferentially connected to the traction sheave 1, thereby connecting the mounting frame 2 to the traction sheave 1. Figure 1 In the specific embodiment shown, there are two limit wheel sets 3, which allows the mounting frame 2 to be arranged radially along the traction wheel 1. Then, the elastic detection element 42 on the detector 4 is aligned with the wheel groove 101 of the traction wheel 1, so that the elastic detection element 42 can be accurately inserted into each wheel groove 101 for detection.

[0046] Additionally, when the traction sheave 1 rotates, it should be noted that since a steel cable is still attached to the traction sheave 1, only the wheel groove 101 near the ground is exposed. Therefore, the detector 4 needs to be positioned below the traction sheave 1. Secondly, it should be clarified that because the traction sheave 1 is in operation, and the limit wheel assembly 3 is located between the mounting frame 2 and the end face of the traction sheave 1, a linear actuator such as a hydraulic rod or electric actuator can be installed on the mounting frame 2. This allows the limit wheel assembly 3 to slide linearly along the length of the mounting frame 2 under the drive of the linear actuator. This eliminates the need for manual adjustment of the position of the limit wheel assembly 3 on the mounting frame 2, preventing the operator from getting too close to the operating traction sheave 1 and increasing safety hazards. After the rotating wheel 301 of the limit wheel assembly 3 is installed on the peripheral wall of the traction sheave 1, the hydraulic rod or electric actuator ensures stable contact between the rotating wheel 301 of the limit wheel assembly 3 and the traction sheave 1.

[0047] Specifically, for example, the traction sheave 1 is installed on the elevator drive, or the traction sheave 1 is in working condition. At this time, the wheel 301 rolls with the rotation of the traction sheave 1. The mounting bracket 2 is fixed to the ground by bolts or directly fixed to the outer shell 10 of the drive by the limiting pressure block 9. Therefore, the position of the mounting bracket 2 in space remains fixed. Due to the rolling cooperation between the wheel 301 and the circumferential surface of the traction sheave 1, the detector 4 can pass through the entire outer circumferential surface of the traction sheave 1 when the traction sheave 1 rotates. At this time, the elastic detection element 42 continuously abuts against the inner wall of the wheel groove 101, transmitting the change in contact pressure caused by the wear of the wheel groove 101 to the pressure sensing unit 41 of the detector 4, realizing the real-time detection of the wear condition of the wheel groove 101 of the traction sheave 1 during operation.

[0048] In the above scheme, the rolling engagement between the roller 301 of the limiting wheel set 3 and the circumferential surface of the traction wheel 1 ensures stable positioning of the traction wheel 1 when it is stationary, and maintains its relative position while the traction wheel 1 is rotating. This achieves full-condition detection in both static and running states, solving the problem that existing automated devices can only adapt to a single state and significantly improving the applicability of the detection. The elastic contact between the elastic sensing element 42 and the inner wall of the wheel groove 101, along with the sensing unit 41, measures the deformation, replacing the traditional method of manually using vernier calipers. This reduces labor intensity and improves detection efficiency, while also avoiding the drawbacks of manual inspection. The system ensures that any oversights are detected and that wear is promptly captured. The elastic detection element 42 can adapt to minor undulations on the surface of the wheel groove 101 and slight vibrations during operation, maintaining reliable contact at all times. The multiple rotating wheels 301 of the limiting wheel set 3 can stably limit the relative position of the device and the traction wheel 1, reducing detection deviation and ensuring the stability and accuracy of the detection. In addition, the mounting frame 2 is arranged radially and the limiting wheel set 3 is slidably installed, which can adapt to the installation requirements of traction wheels 1 of different sizes. The elastic adjustment capability of the elastic detection element 42 can also accommodate the initial size differences of the wheel groove 101, effectively improving the versatility and structural adaptability of the device.

[0049] The detection device can adapt to the detection needs under both stationary and rotating operating conditions of the traction sheave 1, overcoming the problem of poor applicability of existing automated detection devices. The sensing unit 41 measures the elastic deformation of the elastic detection element 42 and transmits it to the detector 4, realizing automated detection of the wear condition of the wheel groove 101 of the traction sheave 1. Compared with manual inspection, this greatly improves detection efficiency, reduces labor intensity, and enables timely detection of wear problems in the wheel groove 101, ensuring the safe operation of the elevator.

[0050] Furthermore, there are several detectors 4, and the elastic detection element 42 of each detector 4 corresponds one-to-one with the groove 101 of the traction wheel 1. By setting multiple detectors 4 to measure different grooves 101 at the same time, the detection speed and detection accuracy can be improved. Moreover, the wear data of different grooves 101 of the same traction wheel 1 can be referenced with each other to improve the accuracy of detection.

[0051] For example, such as Figure 2 and Figure 3As shown, the mounting frame 2 is L-shaped, including a longitudinal frame 201 and a transverse frame 202. The limiting wheel assembly 3 is movably connected to the longitudinal frame 201. The user can adjust the distance between the limiting wheel assemblies 3 according to the size of the traction sheave 1, enabling the detection device to detect traction sheaves 1 of various sizes. Optionally, the longitudinal frame 201 can be arranged radially along the length of the traction sheave 1, and can have a T-shaped mounting groove 2011 extending along its length. This groove allows the limiting wheel assembly 3 to be movably connected to the longitudinal frame 201 via the T-shaped mounting groove 2011. After the limiting wheel assembly 3 is in place, it can be positioned using bolts, clips, or fixing pins. The T-shaped mounting groove 2011 facilitates the installation and position adjustment of the limiting wheel assembly 3 and the detector 4, accommodating traction sheaves 1 of different specifications. It is understood that the connection method between the limiting wheel assembly 3 and the longitudinal frame 201 is not limited to this.

[0052] A crossbar frame 202 is located at one end of the longitudinal frame 201 and is perpendicular to the longitudinal frame 201. The detector 4 is mounted on the crossbar frame 202. Specifically, when the mounting frame 2 is connected to the traction sheave 1, the detector 4 is located on the side of the mounting frame 2 facing the traction sheave 1. Optionally, the crossbar frame 202 is provided with a stop block 6 and a pressing block 7 that can slide along the crossbar frame 202. The pressing block 7 has a threaded hole in its center. A screw is provided on the crossbar frame 202 along its length, and the screw is threadedly connected to the threaded hole of the pressing block 7. By rotating the screw, the pressing block 7 can slide along the crossbar frame 202. A placement space is formed between the stop block 6 and the pressing block 7. Several detectors 4 are spaced apart in this placement space. The pressing block 7 can press against the side wall of the detector 4 to achieve fixation. After the pressing block 7 slides into place, it is fixed by bolts.

[0053] When installing detector 4, firstly, select an appropriate number of detectors 4 according to actual testing requirements, such as the number of wheel grooves 101. Then, place detector 4 in the placement space between stop block 6 and pressure block 7. By sliding pressure block 7, apply pressure to the side wall of detector 4, thereby fixing detector 4 to the crossbar frame 202. Limit wheel assembly 3 and detector 4 can slide along the T-shaped mounting groove 2011 on longitudinal frame 201. Adjust their positions on longitudinal frame 201 according to the actual size of traction wheel 1 and testing requirements. After adjustment, position them with bolts. Fixing detector 4 with stop block 6 and pressure block 7 facilitates installation and disassembly, while ensuring the stability of detector 4 during the testing process and ensuring the accuracy of testing data.

[0054] The traction sheave 1 typically vibrates during operation, and there are also forces interacting between the traction sheave 1 and the detection device, all of which affect the accuracy of the detection results. In some examples, the limiting wheel assembly 3 is mounted on the longitudinal rod frame 201, and the other end of the longitudinal rod frame 201 is equipped with a limiting pressure block 9. The limiting pressure block 9 can be mounted on the housing frame 10 of the driver that drives the traction sheave 1 to rotate. The limiting pressure block 9 cooperates with the limiting wheel assembly 3 to limit and fix the longitudinal rod frame 201, reducing the impact of vibration and forces on the detection results and improving the accuracy of the detection results.

[0055] Optional, for example, such as Figure 3 and Figure 4 As shown, when installing the detection device, the limiting wheel set 3 is brought into contact with the peripheral wall of the traction sheave 1. By adjusting the position of the longitudinal rod frame 201, the limiting pressure block 9 is brought into contact with the top of the drive housing frame 10. The limiting pressure block 9 and the limiting wheel set 3 form a clamping force on the longitudinal rod frame 201, thereby fixing the longitudinal rod frame 201 in a suitable position. However, the bottom of the mounting frame 2 also needs to be fixed. For example, the bottom of the mounting frame 2 only needs to be supported when detecting the traction sheave 1 in operation. The simplest way is to embed a wedge-shaped pad between the bottom end of the mounting frame 2 and the ground, or to directly fix the mounting frame 2 to the ground with anchor bolts. The anchor bolt fixing method is suitable for situations where the device is installed on the outside of the traction sheave 1 for long-term real-time detection. During the detection process, whether the traction sheave 1 is stationary or rotating, the limiting pressure block 9 and the limiting wheel set 3 can maintain the stability of the longitudinal rod frame 201 and prevent it from shifting.

[0056] Therefore, the combined use of the limiting pressure block 9 and the limiting wheel set 3 enhances the limiting and fixing effect on the longitudinal rod frame 201, enabling the detection device to perform stable detection during the operation of the traction wheel 1, avoiding the impact of device shaking on detection accuracy, and improving the reliability of the detection device.

[0057] In some examples, the limiting wheel assembly 3 includes two rotating wheels 301 and a mounting assembly 31. The two rotating wheels 301 are respectively used to fit against the inner and outer circumferential surfaces of the traction wheel 1 to clamp the sidewall of the traction wheel 1. The mounting assembly 31 is movably connected to the mounting frame 2. Both rotating wheels 301 are connected to the mounting assembly 31. The mounting assembly 31 can adjust the distance between the two rotating wheels 301.

[0058] For example, such as Figure 4 and Figure 5As shown, the position of the mounting assembly 31 on the longitudinal frame 201 is adjusted according to the circumferential wall size of the traction sheave 1, so that adjacent rotating wheels 301 are close to each other and mounted on the circumferential wall of the traction sheave 1. When the traction sheave 1 is stationary, the rotating wheel 301 can slide radially with the mounting frame 2; when the traction sheave 1 rotates, the rotating wheel 301 rotates with the traction sheave 1. The mounting assembly 31 can drive the rotating wheel 301 to flexibly adjust its position on the longitudinal frame 201, adapting to traction sheaves 1 of different diameters, thus improving the versatility of the detection device.

[0059] Furthermore, for example, such as Figure 5 As shown, a gear ring 14 is detachably mounted on the end face of the traction sheave 1 away from the drive unit's housing frame 10. At least one rotating wheel 301 is a gear, which meshes with the gear ring 14. When inspecting a stationary traction sheave 1, the gear ring 14 is mounted on the end face of the traction sheave 1, causing the gear wheel 301 to mesh with it. The operator manually pushes the mounting bracket 2, causing the gear wheel 301 to move along the gear ring 14. Due to the meshing transmission between the gear wheel 301 and the gear ring 14, slippage of the gear wheel 301 during movement is prevented, ensuring that the detector 4 stably inspects the wheel groove 101 during the rotation of the traction sheave 1.

[0060] Furthermore, the mounting assembly 31 includes an adjusting rod 312 and two sliding blocks 311. Each sliding block 311 is connected to one of the two rotating wheels 301, and both sliding blocks 311 are movably connected to the longitudinal frame 201. Specifically, these sliding blocks 311 are slidably mounted on the longitudinal frame 201 along its length, with each sliding block 311 corresponding to one rotating wheel 301. A bearing 304 is provided on each sliding block 311, and the axle 302 of the rotating wheel 301 is fixedly inserted into the bearing 304. Adjacent rotating wheels 301 are mounted on the circumferential wall of the traction sheave 1 after being brought close together. Both sliding blocks 311 are movably connected to the adjusting rod 312, which can be a round rod. After the two sliding blocks 311 are adjusted, they can be fixed to the adjusting rod 312 using fasteners. Specifically, the fastener is a locking bolt. A threaded hole is opened on the upper side wall of the sliding block 311, and the locking bolt is threaded into the threaded hole. After the sliding block 311 is adjusted, the locking bolt is tightened so that the end of the locking bolt abuts against the side wall of the adjusting rod 312, thereby locking and fixing the sliding block 311 and the adjusting rod 312.

[0061] Furthermore, a retaining ring 303 is provided on the end face of the wheel 301 near the longitudinal strut frame 201. The retaining ring 303 can fit against the end face of the traction sheave 1 to limit the wheel 301 and prevent it from moving in the axial direction. During the testing process, whether the traction sheave 1 is stationary or rotating, the retaining ring 303 can ensure that the wheel 301 remains in the correct position, making stable contact between the wheel 301 and the peripheral wall of the traction sheave 1. This avoids affecting the normal operation of the testing device due to displacement of the wheel 301, thus improving the reliability of the testing device.

[0062] In some examples, a mounting plate 12 is provided on the end of the longitudinal strut 201 away from the transverse strut 202. The mounting plate 12 is a rectangular plate with through holes. An adjusting handle 11 is also provided on the mounting plate 12. It should be noted that the adjusting handle 11 includes a fixed base mounted on the top of the mounting plate 12. The adjusting handle 11 has a grip, one end of which is hinged to the fixed base. A connecting rod is also provided. A limiting block 9 is provided on the end of the connecting rod away from the grip. The limiting block 9 and the grip are located on opposite sides of the mounting plate 12. When it is necessary to press or release the limiting block 9 against the drive housing frame, the pressure of the limiting block 9 on the drive housing frame 10 can be adjusted simply by rotating the adjusting handle 11.

[0063] For example, such as Figure 5 and Figure 7 As shown, when installing the testing device, loosen the adjusting handle 11, place the longitudinal rod frame 201 in a suitable position so that the limiting pressure block 9 contacts the drive housing frame 10, and then rotate the adjusting handle 11 so that the movable end of the adjusting handle 11 moves the limiting pressure block 9, applying pressure to the drive housing frame 10. Adjust the pressure according to actual needs to firmly fix the longitudinal rod frame 201 to the drive housing frame 10. The setting of the adjusting handle 11 makes it more convenient and quick to adjust the pressure of the limiting pressure block 9, and can flexibly adjust the fixing force according to different installation environments and drive housing frame structures, ensuring that the longitudinal rod frame 201 is installed firmly and reliably, while also facilitating the installation and disassembly of the testing device.

[0064] In some examples, a display 5 is mounted on the strut 201, and the display 5 is electrically connected to the detector 4.

[0065] For example, such as Figure 1As shown, the wires connecting the display 5 and the detector 4 are embedded within the longitudinal support frame 201. The display 5 can display the wear-related data of the wheel groove 101 detected by the detector 4 in real time. Specifically, the display 5 and the sensing unit 41 of the detector 4 are connected through an electrical signal transmission line. The sensing unit 41 converts the deformation signal of the elastic detection element 42 into a recognizable electrical signal (such as an analog voltage signal or a digital pulse signal), and then transmits it to the display 5 in real time through the connection line. The processing module inside the display 5 analyzes and converts the received electrical signal into the corresponding wear data of the wheel groove 101, and displays it intuitively in the form of numbers, curves, or charts. At the same time, a safety threshold can be preset. When the wear amount approaches or exceeds the threshold, the display 5 issues an alarm signal through warning lights, text reminders, etc., so that the staff can monitor the wear status of the traction wheel 1 in real time.

[0066] For example, such as Figure 2 As shown, a ball bearing 8 is embedded in the movable end of the elastic detection element 42, allowing it to roll freely on the inner wall of the wheel groove 101. When the elastic detection element 42 abuts against the inner wall of the wheel groove 101, the ball bearing 8 contacts the inner wall of the wheel groove 101. As the traction wheel 1 rotates or the mounting bracket 2 slides, the ball bearing 8 rolls on the inner wall of the wheel groove 101, converting the sliding friction between the elastic detection element 42 and the inner wall of the wheel groove 101 into rolling friction. The ball bearing 8 significantly reduces the frictional resistance between the elastic detection element 42 and the inner wall of the wheel groove 101, reducing wear on the inner wall of the wheel groove 101 and the elastic detection element 42 during the detection process, improving the service life of the elastic detection element 42, and ensuring accurate transmission of contact pressure change signals, thus improving detection accuracy.

[0067] In some examples, a handle 13 is provided on the middle of the outer side of the longitudinal frame 201. The position of the handle 13 facilitates hand operation by the inspector. Understandably, when installing, adjusting, and disassembling the inspection device, the inspector can move the mounting frame 2 by holding the handle 13. The handle 13 also provides a stable grip point for the inspector, facilitating control of the position and status of the inspection device and making operation easier. The handle 13 improves the portability and ease of operation of the inspection device, allowing inspectors to operate it more easily, especially in situations requiring frequent movement of the inspection device, significantly reducing the workload of inspectors and improving work efficiency.

[0068] During the inspection process, when inspecting a stationary traction sheave 1, the operator can hold the handle 13 with one hand and push the longitudinal rod frame 201 close to the wheel 301 with the other hand. This will stably push the longitudinal rod frame 201 to rotate along the outer peripheral wall of the traction sheave 1. When inspecting a running traction sheave 1, the operator can hold the handle 13 on the mounting frame 2, install the wheel 301 on the peripheral wall of the traction sheave 1, and then continue to hold the handle 13 to keep the mounting frame 2 stable. At this time, the running traction sheave 1 can be inspected.
