Technical Field
[0001] The utility model relates to the technical field of bearing detection, in particular to a wear detection device for an elevator compensating sheave bearing. Background Art
[0002] The detection of bearing wear is a delicate and crucial process, which involves multiple aspects of inspection and evaluation; the wear of bearings will cause many faults in installed equipment. Therefore, it is necessary to detect the wear of bearings in equipment, which is the basis for ensuring the stable use of mechanical equipment.
[0003] However, when the traditional wear detection device for an elevator compensating sheave bearing is in use, in order to avoid complex disassembly and detection, some measuring devices are often introduced to cooperate with the probe to detect the diameters of different positions of the bearing, so as to judge the wear. However, this operation is not only complicated in process, but also the detection result is not obvious and inconvenient to use. Summary of the Utility Model
[0004] The utility model discloses a wear detection device for an elevator compensating sheave bearing, aiming to solve the technical problem that when the traditional wear detection device for an elevator compensating sheave bearing is in use, in order to avoid complex disassembly and detection, some measuring devices are often introduced to cooperate with the probe to detect the diameters of different positions of the bearing, so as to judge the wear. However, this operation is not only complicated in process, but also the detection result is not obvious and inconvenient to use.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A wear detection device for an elevator compensating sheave bearing, comprising a track and a movable frame slidably connected to the track. The inner wall of the movable frame is connected with a compensating sheave body through a bearing, and further comprises: a limit installation mechanism: the limit installation mechanism is connected to the movable frame; a collection and detection mechanism: the collection and detection mechanism comprises a mounting block arranged at the bottom of the compensating sheave body. A collection box is arranged on the outer wall of the top of the mounting block. An opening is arranged at the top of the collection box. The opening is located directly below the compensating sheave body. Light strips are arranged on both inner walls near both ends of the opening. A reflective coating is arranged on the inner wall of the bottom of the collection box.
[0007] In this solution, the collection box set can be fixed below the main body of the return pulley through the limit installation mechanism. Then, an appropriate amount of lubricant is dropped at the bearing position of the main body of the return pulley. After maintaining the stable operation of the collection box and the main body of the return pulley for a certain period, the collection box is removed. The wear of the bearing is detected by observing the lubricant flowing down. If the color of the lubricant is normal and there are no metal impurities, it indicates that the bearing is still in good use. If it is found that the lubricant turns black, thickens, or contains metal particle impurities, it means that the bearing has shown wear. The detection result is intuitive and accurate.
[0008] In a preferred solution, the limit installation mechanism includes sliding holes provided on the inner walls of both sides of the installation block. Slide rods are slidably connected to the inner walls of the two sliding holes. The opposite ends of the two slide rods are both threadedly connected with first adjusting rods. The top ends of the two first adjusting rods are both connected with support rods through bearings. A connecting plate is provided on the outer wall of the bottom of the installation block. A knob is provided on the outer wall of one side of the connecting plate. A rotating rod is installed at one end of the knob. A driving roller is provided at one end of the rotating rod. Thread grooves are opened at the opposite ends of the two slide rods. The same second adjusting rod is installed on the inner walls of the two thread grooves. A driven roller is provided on the outer wall of the second adjusting rod. The same linkage belt is sleeved on the outer walls of the driving roller and the driven roller. The first adjusting rod is a unidirectional threaded rod, and the second adjusting rod is a bidirectional threaded rod.
[0009] By setting the limit installation mechanism, the knob can be adjusted to drive the driving roller to rotate. Then, relying on the linkage effect of the driving roller, the linkage belt, and the driven roller, the second adjusting rod is driven to rotate, thereby driving the two slide rods to move in opposite directions along the sliding holes. In this way, the support rods on both sides are supported to abut against the inner side wall of the movable frame. At the same time, rotating the first adjusting rod can adjust the longitudinal height between the installation block and the support rod, so that the collection box is more closely attached to the lower part of the return pulley main body, and the adaptability is stronger.
[0010] As can be seen from the above, an elevator return pulley bearing wear detection device includes a track and a movable frame slidably connected to the track. The inner wall of the movable frame is connected with the main body of the return pulley through a bearing, and further includes: a limit installation mechanism: the limit installation mechanism is connected to the movable frame; a collection and detection mechanism: the collection and detection mechanism includes an installation block provided at the bottom of the main body of the return pulley. A collection box is provided on the outer wall of the top of the installation block. An opening is provided at the top of the collection box. The opening is located directly below the main body of the return pulley. Light strips are provided on the inner walls of both sides near the two ends of the opening. A reflective coating is provided on the inner wall of the bottom of the collection box. The elevator return pulley bearing wear detection device provided by the present invention can collect the lubricant used by the bearing on the main body of the return pulley, and detect whether the bearing is worn through the information fed back by the collected lubricant. The overall process is convenient to use, and the detection result is intuitive and accurate. Description of the Drawings

Detailed Description of the Preferred Embodiments
[0016] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0017] A wear detection device for an elevator counterweight sheave disclosed by the present utility model is mainly applied to the scenario where in the use of a traditional wear detection device for an elevator counterweight sheave, in order to avoid complex disassembly and assembly for detection, some measuring devices are often introduced to cooperate with the probe to detect the diameters of different positions of the bearing, so as to judge the wear. However, this operation is not only complicated in process, but also the detection result is not obvious and it is not convenient to use.
[0018] Refer to Figure 1 、 Figure 2 and Figure 3, An elevator compensating sheave bearing wear detection device, comprising a track 1 and a movable frame 2 slidably connected to the track 1. A compensating sheave body 5 is connected to the inner wall of the movable frame 2 through a bearing, and further comprising: a limit installation mechanism: the limit installation mechanism is connected to the movable frame 2;
[0019] A collection and detection mechanism: The collection and detection mechanism includes a mounting block 4 provided at the bottom of the compensating sheave body 5. A collection box 6 is provided on the outer wall of the top of the mounting block 4. An opening is provided at the top of the collection box 6. The opening is located directly below the compensating sheave body 5. Light bars 8 are provided on both inner walls near the two ends of the opening. A reflective coating is provided on the bottom inner wall of the collection box 6.
[0020] Wherein, the collection box 6 is arranged in an arc structure, and the width of the opening is greater than the thickness of the compensating sheave body 5. An opening with a suitable width can fully collect the lubricant flowing down from the compensating sheave body 5.
[0021] Specifically, the provided collection box 6 can be fixed below the compensating sheave body 5 through the limit installation mechanism. Then, an appropriate amount of lubricant is dropped into the bearing position of the compensating sheave body 5. After maintaining the stable operation of the collection box 6 and the compensating sheave body 5 for a certain period, the collection box 6 is removed. The wear of the bearing is detected by observing the flowing lubricant. If the color of the lubricant is normal and there are no metal impurities, it indicates that the bearing is still in good use. If it is found that the lubricant turns black, becomes thick or contains metal particle impurities, it indicates that the bearing has shown wear.
[0022] Refer to Figure 3 and Figure 4 , In a preferred embodiment, the limit installation mechanism includes sliding holes provided on both inner walls of the mounting block 4. Slide rods 9 are slidably connected to the inner walls of the two sliding holes. The opposite ends of the two slide rods 9 are both connected with first adjusting rods 7 through threads. The top ends of the two first adjusting rods 7 are both connected with support rods 3 through bearings. The top ends of the two support rods 3 are both provided with bent structures, and anti-slip pads 10 are provided on the outer walls of the opposite sides of the two support rods 3. The two support rods 3 are respectively hung on the inner walls of both sides of the movable frame 2. A connecting plate 11 is provided on the outer wall of the bottom of the mounting block 4. A knob 12 is provided on one outer wall of the connecting plate 11. One end of the knob 12 is installed with a rotating rod, and one end of the rotating rod is provided with a driving roller 13. Thread grooves are opened at the opposite ends of the two slide rods 9. The same second adjusting rod 16 is installed on the inner walls of the two thread grooves. A driven roller 14 is provided on the outer wall of the second adjusting rod 16. The same linkage belt 15 is sleeved on the outer walls of the driving roller 13 and the driven roller 14.
[0023] Wherein, the first adjusting rod 7 is a unidirectional threaded rod, and the second adjusting rod 16 is a bidirectional threaded rod.
[0024] It should be noted that the support rod 3 of the bending structure can be stably hung on the inner wall of the movable frame 2. Coupled with the increased friction of the anti-slip pad 10, the relative movement between the support rod 3 and the movable frame 2 is effectively avoided.
[0025] Specifically, through the set limit installation mechanism, the knob 12 can be adjusted to drive the rotation of the driving roller 13. Then, relying on the linkage action of the driving roller 13, the linkage belt 15 and the driven roller 14, the second adjusting rod 16 is driven to rotate, and then the two sliding rods 9 are driven to move in the opposite direction along the sliding holes, so that the support rods 3 on both sides are tightly pressed against the inner side wall of the movable frame 2.
[0026] At the same time, rotating the first adjusting rod 7 can adjust the longitudinal height between the mounting block 4 and the support rod 3, so that the collection box 6 is more closely attached to the lower part near the anti-rope wheel body 5.
[0027] Working principle: When in use, first use the second adjusting rod 16 in the limit fixing mechanism to fix the mounting block 4 to the movable frame 2, then rotate the first adjusting rod 7 to adjust the height between the collection box 6 and the anti-rope wheel body 5, and then drop an appropriate amount of lubricant on the bearing position of the mounted anti-rope wheel body 5. After maintaining the stable operation of the collection box 6 and the anti-rope wheel body 5 for a certain period, the collection box 6 is removed. The wear of the bearing is detected by observing the flowing lubricant. If the color of the lubricant is normal and there are no metal impurities, it indicates that the bearing is still in good use. If it is found that the lubricant turns black, thickens or contains metal particle impurities, it indicates that the bearing has been worn. Finally, the specific replacement time is judged according to the amount of metal impurities and the color of the lubricant.
[0028] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
