Description

Technical Field

[0001] This utility model relates to the field of elevator traction sheave technology, and in particular to an elevator traction sheave wear detection device. Background Technology

[0002] The elevator traction sheave is a core component of the elevator drive system, typically made of cast iron or steel, with rope grooves on its surface. It drives the elevator car up and down through friction with the traction steel wire rope, and its performance directly affects the safety and stability of elevator operation. During use, the rope grooves wear down due to long-term friction with the traction steel wire rope. Wear reduces the friction between the rope grooves and the traction steel wire rope, weakening the traction capacity and potentially causing problems such as car slippage and vibration. Therefore, a traction sheave wear detection device is needed to regularly inspect the traction sheave.

[0003] The existing utility model patent with authorization announcement number CN215491433U discloses an elevator traction sheave wear detection device, including a mounting frame. Multiple mounting frames are connected by connecting rods. Multiple ball bearings are provided on the mounting frame. A first screw is fixed inside each ball bearing. Each first screw is fixed with a pulley. Multiple pulleys are connected by a belt. A threaded plate is threadedly connected to the first screw. A fixing plate is provided between two threaded plates. Multiple threaded sleeves are provided through the fixing plate. A second screw is threadedly connected inside each threaded sleeve. A scale is fixed to the top of the fixing plate. A clamping mechanism is fixed to the bottom of the mounting frame.

[0004] The aforementioned utility model patent, while employing multiple second screws to correspond to multiple wheel grooves and determining the wear degree of the wheel grooves by the downward movement of the second screws, is simple and convenient to operate and can effectively detect the wear degree of the wheel grooves. However, when this elevator traction sheave wear detection device detects the wheel grooves of multiple traction sheaves, it requires manually rotating multiple second screws to complete the detection of all wheel grooves. This process is not only time-consuming and labor-intensive, but also has low detection efficiency.

[0005] Therefore, it is necessary to develop an elevator traction sheave wear detection device to address the aforementioned defects. Utility Model Content

[0006] The purpose of this invention is to provide an elevator traction sheave wear detection device that can improve the detection efficiency of the traction sheave and reduce the intensity of manual operation.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses an elevator traction sheave wear detection device, comprising a base plate, a fixing component, and a detection component. Support plates are fixedly connected to the top surfaces of both ends of the base plate, and a horizontal plate is fixedly connected between the top ends of the support plates. The fixing component is disposed between the two support plates and is used to clamp and fix the traction sheave to be tested. The detection component includes a movable plate, the two ends of which are slidably connected to the side walls of the two support plates facing each other. Multiple detection cylinders are fixedly connected to the movable plate at even intervals along its length. The movable plate has several through holes corresponding to the detection cylinders. A detection rod is vertically disposed inside each detection cylinder, the bottom end of which passes through the detection cylinder and the through hole. A sliding plate is fixedly connected to the top end of the detection rod, and the sliding plate is slidably connected to the inner wall of the detection cylinder. A scale line is provided on the outer wall of the detection cylinder. A lifting component is provided on the horizontal plate to drive the movable plate to rise and fall. A limiting component is provided on the movable plate to limit the detection rod so that its bottom end is on the same horizontal line as the bottom surface of the movable plate.

[0009] Furthermore, the lifting component includes a telescopic component, which is vertically fixedly connected to the top surface of the horizontal plate. The telescopic end of the telescopic component passes through the horizontal plate. A U-shaped plate is provided between the horizontal plate and the movable plate. The top surface of the U-shaped plate is fixedly connected to the telescopic end of the telescopic component, and the bottom surfaces of the side plates at both ends of the U-shaped plate are fixedly connected to the movable plate.

[0010] Furthermore, the fixing assembly includes a fixed clamping plate, a movable clamping plate, and a threaded rod. A sliding groove is formed on the top surface of the base plate. The fixed clamping plate is fixedly connected to the top surface of the base plate at one end of the sliding groove, and the movable clamping plate is fixedly connected to the top surface of the base plate at the other end of the sliding groove. The threaded rod is rotatably connected to the inner wall of the sliding groove, and a slider is threaded onto the threaded rod. The movable clamping plate is fixedly connected to the slider. One end of the threaded rod passes through the sliding groove and is fixedly connected to a turntable.

[0011] Furthermore, the limiting component includes a connecting plate, and the side wall of the movable plate is provided with limiting holes that correspond one-to-one with and communicate with the through holes. A plurality of limiting rods corresponding one-to-one with the limiting holes are fixedly connected to the connecting plate. The limiting rods are inserted into the limiting holes. The detection rod is provided with insertion holes that are adapted to the limiting rods. The insertion holes are inserted into the limiting rods.

[0012] Furthermore, mounting plates are fixedly connected to both ends of the sidewall of the movable plate, and the two ends of the connecting plate are slidably connected to the sidewalls of the two mounting plates facing each other.

[0013] Furthermore, the detection cylinder has a vertically formed strip-shaped hole on its side wall, and the scale lines are set on both sides of the strip-shaped hole. An indicator plate is fixedly connected to the side wall of the slide plate, and the indicator plate passes through the strip-shaped hole.

[0014] Furthermore, a lifting rod is vertically fixedly connected to the top surface of the slide plate. The lifting rod passes through the detection cylinder and is slidably connected to it. A limit plate is fixedly connected to the top of the lifting rod, and the same lifting plate is slidably sleeved on the outer wall of several lifting rods.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This invention uses a fixing component to secure the traction sheave to be tested to a base plate. A lifting mechanism drives a moving plate to move downwards until its bottom surface contacts the outer wall of the traction sheave. Then, the limiting component releases the restriction on the detection rods, allowing all the detection rods to automatically fall into the rope groove under gravity. The wear condition of the traction sheave groove can be detected based on the height the detection rods descend. This improves testing efficiency, reduces the intensity of manual operation, and shortens elevator downtime due to testing. Attached Figure Description

At the same time, all parts not described in detail in this utility model are common technologies known to those skilled in the art.

[0026] In one specific embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the assembly includes a base plate 1, a fixing component, and a detection component. Support plates 2 are fixedly connected to the top surfaces of both ends of the base plate 1, and a horizontal plate 3 is fixedly connected between the top ends of the support plates 2. The fixing component is positioned between the two support plates 2 and is used to clamp and fix the traction sheave 4 to be tested. The detection component includes a movable plate 5, whose two ends are slidably connected to the opposite sidewalls of the two support plates 2. Multiple detection cylinders 6 are evenly spaced and fixedly connected to the movable plate 5 along its length. Each detection cylinder 6 corresponds to a rope groove in the traction sheave 4 to be tested. The movable plate 5 has several through holes 7 corresponding to each detection cylinder 6. A detection rod 8 is vertically arranged inside the detection cylinder 6, with its bottom end penetrating the detection cylinder 6 and the through holes 7. The detection rod 8 is positioned opposite the rope groove of the traction sheave 4. A sliding plate 9 is fixedly connected to the top of the detection rod 8, and the sliding plate 9 is slidably connected to the inner wall of the detection cylinder 6. Scale lines 10 are provided on the outer wall of the detection cylinder 6. A lifting component is provided on the horizontal plate 3. The lifting component is used to drive the moving plate 5 to rise and fall. A limiting component is provided on the moving plate 5. The limiting component is used to limit the detection rod 8 so that its bottom end is on the same horizontal line as the bottom surface of the moving plate 5.

[0027] In one specific embodiment of this utility model, such as Figure 1 As shown, the lifting component includes a telescopic component 11, which is vertically fixed to the top surface of the horizontal plate 3, with its telescopic end penetrating through the horizontal plate 3. A U-shaped plate 12 is provided between the horizontal plate 3 and the movable plate 5. The top surface of the U-shaped plate 12 is fixedly connected to the telescopic end of the telescopic component 11, and the bottom surfaces of the side plates at both ends of the U-shaped plate 12 are fixedly connected to the movable plate 5. The telescopic extension and retraction of the telescopic end of the telescopic component 11 can drive the movable plate 5 to rise and fall. It should be noted that the telescopic component 11 specifically adopts a hydraulic cylinder, pneumatic cylinder, or electric push rod, etc., as a driving component with telescopic function.

[0028] In one specific embodiment of this utility model, such as Figure 1 As shown, the fixing assembly includes a fixed clamping plate 13, a movable clamping plate 14, and a threaded rod 15. A groove 16 is formed on the top surface of the base plate 1. The fixed clamping plate 13 is fixedly connected to the top surface of the base plate 1 at one end of the groove 16, and the movable clamping plate 14 is fixedly connected to the top surface of the base plate 1 at the other end of the groove 16. The threaded rod 15 is rotatably connected to the inner wall of the groove 16, and a slider 17 is threaded onto the threaded rod 15. The slider 17 is slidably connected to the groove 16, and the movable clamping plate 14 is fixedly connected to the slider 17. One end of the threaded rod 15 passes through the groove 16 and is fixedly connected to a turntable 18. By rotating the turntable 18, the threaded rod 15 is rotated, causing the slider 17 to move the movable clamping plate 14 within the groove 16, thereby adjusting the distance between the fixed clamping plate 13 and the movable clamping plate 14, and clamping and fixing the traction wheel 4.

[0029] In one specific embodiment of this utility model, such as Figure 2 As shown, the limiting component includes a connecting plate 19. The side wall of the movable plate 5 has limiting holes 20 that correspond one-to-one with and communicate with the through holes 7. Several limiting rods 21, each corresponding one-to-one with the limiting holes 20, are fixedly connected to the connecting plate 19. The limiting rods 21 are inserted into the limiting holes 20. The detection rods 8 have insertion holes 22 that fit the limiting rods 21, and these insertion holes 22 are inserted into the limiting rods 21. Before starting the test, the limiting rods 21 are inserted one-to-one into the limiting holes 20 and the insertion holes 22 on the detection rods 8, ensuring that the bottom end of the detection rods 8 is level with the bottom surface of the movable plate 5, thus ensuring that the initial detection positions of each detection rod 8 are consistent.

[0030] Specifically, mounting plates 23 are fixedly connected to both ends of the side wall of the movable plate 5, and the two ends of the connecting plate 19 are slidably connected to the side walls of the two mounting plates 23 respectively. This facilitates the sliding of the connecting plate 19 along the side wall of the movable plate 5, and makes it easy to insert or remove the limiting rod 21 from the insertion hole 22.

[0031] In one specific embodiment of this utility model, such as Figure 3As shown, a strip-shaped hole 24 is vertically opened on the side wall of the detection cylinder 6, and scale lines 10 are set on both sides of the strip-shaped hole 24. An indicator plate 25 is fixedly connected to the side wall of the slide plate 9, and the indicator plate 25 passes through the strip-shaped hole 24. During the detection process, when the limiting member restricts the detection rod 8, the detection rod 8 moves down under the action of gravity, which drives the slide plate 9 and the indicator plate 25 to move down until the bottom end of the detection rod 8 falls into the rope groove of the traction sheave and contacts the bottom surface of the rope groove. The depth of the rope groove can be read intuitively by the position of the indicator plate 25 on the scale line 10, thereby judging the wear condition of the traction sheave.

[0032] In one specific embodiment of this utility model, such as Figure 1 As shown, a lifting rod 26 is vertically fixedly connected to the top surface of the slide plate 9. The lifting rod 26 passes through the detection cylinder 6 and is slidably connected to it. A limit plate 27 is fixedly connected to the top of the lifting rod 26. The same lifting plate 28 is slidably sleeved on the outer wall of several lifting rods 26. When it is necessary to reset the detection rod 8, the lifting plate 28 is pulled upward, which drives all the detection rods 8 to rise synchronously through the lifting rods 26, further improving the detection efficiency.

[0033] The working principle of this utility model is as follows: When detecting the wear of the traction sheave groove, the traction sheave 4 to be tested is placed between the fixed clamping plate 13 and the movable clamping plate 14. The turntable 18 is rotated to drive the threaded rod 15 to rotate, causing the slider 17 to move the movable clamping plate 14 within the groove 16, so that the movable clamping plate 14 moves towards the fixed clamping plate 13, clamping and fixing the traction sheave 4. The telescopic component 11 is activated, causing the movable plate 5 and the detection component to descend until the bottom surface of the movable plate 5 contacts the groove of the traction sheave to be tested. Then, the connecting plate 19 is moved, causing the limiting rod 21 to move, so that the limiting rod 21 disengages from the insertion hole 22 and enters the limiting hole 20. Under the action of gravity, the detection rod 8 moves down, causing the sliding plate 9 and the indicator plate 25 to move down until the bottom end of the detection rod 8 falls into the rope groove of the traction sheave and contacts the bottom surface of the rope groove. The depth of the rope groove can be read intuitively by the position of the indicator plate 25 on the scale line 10, thereby judging the wear condition of the traction sheave.

[0034] After the test is completed, the telescopic component 11 is activated, which moves the moving plate 5 upward. Then, the lifting plate 28 is pulled upward, and the lifting plate 28 pulls the lifting rod 26 upward, which moves the test rod 8 upward. Then, the connecting plate 19 is moved, which moves the limiting rod 21. The limiting rod 21 is inserted into the insertion hole 22, and the bottom end of the test rod 8 is fixed at a position flush with the bottom surface of the moving plate 5, in preparation for the next traction wheel test.

[0035] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0036] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
