Description

Technical Field

[0001] This invention belongs to the field of elevator technology, and in particular relates to an elevator vibration detection method and system. Background Technology

[0002] With the continuous emergence of high-rise buildings, elevators, as vertical transportation tools within internal structures, have become an indispensable part of people's daily lives. The safety and comfort of elevator use have become crucial technical performance requirements for elevator operation. Currently, elevator vibration testing mainly relies on vibration meters for data collection, followed by adjustments made by testing personnel based on the vibration data. However, vibration meters typically collect data from the elevator car floor, while testing personnel work from the top of the elevator car. Therefore, testing personnel can only roughly navigate the elevator to the location of the vibration issue and then painstakingly pinpoint the exact location. This method has significant errors in identifying vibration issues, is time-consuming and labor-intensive, and heavily relies on the testing personnel's installation and testing experience. It often leads to incorrect or unsuccessful identification of vibration issues, resulting in poor overall elevator comfort and low efficiency in comfort adjustments. Therefore, there is an urgent need for an elevator vibration testing method that allows testing personnel to accurately reach the rectification location and accurately determine the vibration issues. Summary of the Invention

[0003] The purpose of this invention is to provide an elevator vibration detection method and system that enables inspection personnel to accurately reach the rectification location and accurately determine the vibration non-compliance point, saving time and effort, and solving problems such as poor overall elevator installation comfort and low efficiency of elevator comfort adjustment due to incorrect or undetectable vibration non-compliance points.

[0004] This invention is achieved through the following technical solution:

[0005] An elevator vibration detection method includes a position indicator device installed on the car top guardrail. The position indicator device includes a fixed base, a clamping mechanism, and a position indicator needle. The clamping mechanism is disposed on the fixed base and is used to clamp or release the car top guardrail. The position indicator needle is slidably disposed on the top of the fixed base.

[0027] Furthermore, it also includes a pressure seat and a second screw. A groove is provided on the position indicator needle along its length. The position indicator needle is sleeved on the outside of the first side plate through the groove. A second threaded hole and two second through holes are provided on the top plate located on one side of the first side plate.

The horizontal part of the information indicator light is located on the top of the information box, and the vertical part of the information indicator light is located on one side of the information box.

[0030] The present invention also provides an elevator vibration detection system, including a position indicator device installed on the car top guardrail. The position indicator device includes a fixed base, a clamping mechanism and a position indicator needle.

Vibration failure points are determined based on the vibration data from elevator operation, and these failure points are converted into target rectification points for the inspectors. By comparing the target pulse count at the target rectification point with the cumulative pulse count of the encoder on the traction sheave, the elevator is moved to the target rectification point, enabling the inspectors to accurately reach the rectification position. Then, the position indicator needle points to the specific location of the vibration failure on the vertical guide rail, facilitating the inspectors' determination of the failure location, saving time and effort, and solving problems such as poor overall elevator installation comfort and low efficiency in elevator comfort adjustment due to incorrect or undetectable vibration failure points.

[0052] Please see Figure 2 and Figure 6 , Figure 2 This is a schematic diagram of the position indicator device in the elevator vibration detection method of the present invention. Figure 6 This is a schematic diagram of the position indicator device installed on the car top guardrail in the elevator vibration detection method of the present invention. An elevator vibration detection method includes a position indicator device installed on the car top guardrail 9. The position indicator device includes a fixed base 1, a clamping mechanism 2, and a position indicator needle 3. The clamping mechanism 2 is disposed on the fixed base 1 and is used to clamp or release the car top guardrail 9. The position indicator needle 3 is slidably disposed on the top of the fixed base 1 and is used to indicate the position where vibration is unqualified.

[0053] Please refer to the following: Figure 3 , Figure 4 and Figure 5 , Figure 3 This is a side view of the position indication device in the elevator vibration detection method of the present invention. Figure 4 This is a front view of the position indicating device in the elevator vibration detection method of the present invention. Figure 5 This is a top view of the position indicating device in the elevator vibration detection method of the present invention. In one embodiment, the fixed base 1 is U-shaped and includes a top plate 11, a bottom plate 12, and a vertical plate 13 connecting the top plate 11 and the bottom plate 12. The clamping mechanism 2 includes a push seat and a first screw 21. The push seat is U-shaped and includes a first side plate 22, a second side plate 23, and a first horizontal plate 24 connecting the first side plate 22 and the second side plate 23. A first threaded hole and two first through holes are provided on the top. The first side plate 222 and the second side plate 23 are respectively inserted into the two first through holes. The first horizontal plate 24 is located below the top plate 11. The first screw 21 is threadedly connected to the first threaded hole, and the bottom end of the first screw 21 is rotatably connected to the first horizontal plate 24. A first rubber block 25 is provided at the bottom of the first horizontal plate 24, and a second rubber block 14 is provided at the top of the bottom plate 12 corresponding to the position of the first rubber block 25. By rotating the first screw 21, the first horizontal plate 24 is moved vertically, controlling the first rubber block 25 to move up and down. This, in turn, clamps the car roof guardrail 9 with the first rubber block 25 and the second rubber block 14, securing the fixing base 1 to the car roof guardrail 9. The first side plate 22 and the second side plate 23 cooperate with the two first through holes, serving as guides to ensure that the first rubber block 25 can only move up and down and cannot detach from the fixing base 1.

[0054] In one embodiment, anti-slip textures 4 are provided on the opposing surfaces of the first rubber block 25 and the second rubber block 14. The anti-slip textures 4 consist of multiple toothed grooves and are used to prevent slippage and avoid slippage when the first rubber block 25 and the second rubber block 14 clamp the car roof guardrail 9.

[0055] In one embodiment, a plurality of first arc-shaped holes 26 are vertically spaced on the first rubber block 25, with the length of the plurality of first arc-shaped holes 26 decreasing sequentially from top to bottom. A plurality of second arc-shaped holes 15 are vertically spaced on the second rubber block 14, with the length of the plurality of second arc-shaped holes 15 decreasing sequentially from bottom to top. Considering that the car roof guardrail 9 may be cylindrical, a plurality of first arc-shaped holes 26 of different lengths are provided on the first rubber block 25, with the arc center of the first arc-shaped holes 26 facing downwards. A plurality of second arc-shaped holes 15 of different lengths are provided on the second rubber block 14, with the arc center of the second arc-shaped holes 15 facing upwards. Both the first arc-shaped holes 26 and the second arc-shaped holes 15 extend along the length direction of the car roof guardrail 9. When the first rubber block 25 and the second rubber block 14 clamp the cylindrical car roof guardrail 9, the first arc hole 26 and the second arc hole 15 of different lengths will be recessed and deformed inward, increasing the contact area between the first rubber block 25 and the second rubber block 14 and the cylindrical car roof guardrail 9, thereby firmly fixing the fixing base 1 to the car roof guardrail 9.

[0056] In one embodiment, two support plates 29 are spaced apart at the top of the first horizontal plate 24, and a limiting plate 210 is connected between the two support plates 29. The limiting plate 210 has a rotating hole, and a rotating rod 27 is provided at the bottom of the first screw 21. The rotating rod 27 is rotatably disposed in the rotating hole, and a rotating plate 28 is provided at the bottom of the rotating rod 27 that abuts against the first horizontal plate 24. The rotating plate 28 can prevent the first screw 21 from disengaging, realizing the rotational connection between the first screw 21 and the first horizontal plate 24.

[0057] In one embodiment, the position indicating device of the present invention further includes a pressure seat 5 and a second screw 6. A groove 31 is provided on the position indicating needle 3 along its length direction. The position indicating needle 3 is sleeved on the outside of the first side plate 22 through the groove 31. A second threaded hole and two second through holes are provided on the top plate 11 at one side of the first side plate 22. The pressure seat 5 is U-shaped and includes a third side plate 51, a fourth side plate 52 and a second horizontal plate 53 connecting the third side plate 51 and the fourth side plate 52. A third through hole is provided on the second horizontal plate 53. The third side plate 51 and the fourth side plate 52 are respectively inserted into the two second through holes, and the second horizontal plate 53 is located above the position indicating needle 3. The first screw 21 passes through the third through hole and the groove 31 in sequence and is threadedly connected to the second threaded hole. The second screw 6, the first side plate 22, and the slide groove 31 work together to guide and restrict the movement of the position indicator needle 3. When the position indicator needle 3 is in position, rotating the second screw 6 moves the second horizontal plate 53 downward, pressing the position indicator needle 3 and fixing its position. The third side plate 51 and the fourth side plate 52 work with the two second through holes to guide and ensure that the pressure seat 5 can only move up and down.

[0058] In one embodiment, one end of the position indicator needle 3 is a pointed tip, and the other end is bent upward to form a baffle 32. The baffle 32 on the position indicator needle 3 facilitates pushing the position indicator light and prevents the position indicator needle 3 from sliding out of the pressure seat 5.

[0059] The elevator vibration detection method of the present invention includes the following steps:

[0060] S1. Determine the starting point of the elevator car;

[0061] S2. Obtain vibration data during elevator car operation and determine several vibration non-compliance points based on the vibration data;

[0062] S3. Obtain the preset height value. For each vibration non-conforming point, calculate the distance between the vibration non-conforming point and the starting point. Based on the height value and the distance value, obtain the target value. Determine the target rectification point of the vibration non-conforming point based on the target value.

[0063] S4. Convert the target value into the target pulse count to obtain the target pulse count corresponding to the target rectification point;

[0064] S5. Control the elevator car to start running from the starting point and obtain the cumulative number of pulses during the operation of the elevator car based on the encoder installed on the traction sheave;

[0065] S6. For each target rectification point, determine whether the difference between the cumulative number of pulses and the target number of pulses corresponding to the target rectification point is within the preset threshold range.

[0066] S7. If so, determine that the elevator car has reached the target rectification point, stop the elevator operation, push the position indicator, and indicate the vibration non-compliance point corresponding to the target rectification point through the position indicator.

[0067] In step S1 above, the elevator car generally runs along the vertical guide rail in the shaft. Therefore, the highest or lowest point of the elevator car running in the shaft can be set as the starting point of the elevator car.

[0068] In step S2 above, a vibration meter is installed on the elevator car floor to acquire vibration data of the elevator car running on the vertical guide rail. This vibration data forms a vibration curve. An EVA vibration meter can be used, which acquires vibration data of the elevator car running on the vertical guide rail in the XYZ three dimensions. The vibration curve formed by the vibration data is compared with a preset standard vibration curve. If the vibration data at a certain point exceeds the vibration data on the standard vibration curve, then that point is a vibration non-compliance point, thus identifying several vibration non-compliance points.

[0069] In step S3 above, the preset height value is the distance from the vibrator to the position indicator. Since the vibrator typically collects data from the elevator car floor, and the inspector's working plane is the top of the elevator car, after determining the non-compliant vibration location based on the vibration data, for each non-compliant vibration point, the distance between the non-compliant vibration point and the starting operating point is calculated. If the highest point of the elevator car in the hoistway is taken as the starting operating point, the height value and the distance value are added together to obtain the target value. The target rectification point for the non-compliant vibration point is determined by the target value. This target rectification point is the distance that the inspector needs to control the elevator car to descend, thereby converting the non-compliant vibration point into the inspector's target rectification point.

[0070] In step S4 above, since the distance the elevator car moves is fixed for each degree the traction sheave rotates, the target value can be converted into a corresponding number of pulses. Therefore, the set pulse count of the encoder on the traction sheave connected to the elevator car is obtained; the set pulse count is the movement value of the elevator car when the traction sheave rotates by a unit angle. Therefore, the rotation angle of the traction sheave is obtained by dividing the target value by the movement value, thus obtaining the number of times the encoder records data, i.e., the target pulse count corresponding to each target rectification point.

[0071] In step S5 above, the elevator car is moved to the starting point and controlled to start running from the starting point. At this time, the encoder starts recording the number of pulses, thereby obtaining the cumulative number of pulses during the operation of the elevator car.

[0072] In steps S6 and S7 above, the cumulative pulse count represents the distance the elevator car has traveled, and the target pulse count represents the distance the elevator car needs to travel. Therefore, for each target rectification point, it is determined whether the difference between the cumulative pulse count and the target pulse count corresponding to the target rectification point is within a preset threshold range. When the cumulative pulse count is close to the target pulse count corresponding to the corresponding target rectification point, it indicates that the top of the elevator car has reached the target rectification point. The elevator is then temporarily put into operation. At this time, the inspector accurately arrives at the rectification position and then uses the moving position indicator to indicate the specific location of the vibration non-compliance on the vertical guide rail. This facilitates the inspector in quickly identifying the vibration non-compliance location, making it easier for the inspector to rectify the elevator, saving time and effort, and solving problems such as poor overall elevator installation comfort and low efficiency in elevator comfort adjustment caused by incorrectly finding or failing to find the vibration non-compliance point. After the inspector completes the rectification, the "continue running" button can be pressed again.

[0073] Specifically, several target rectification points can be numbered. The elevator car starts running from the initial running point and checks whether the difference between the cumulative pulse count and the target pulse count corresponding to the first target rectification point is within a preset threshold range. If it is within the threshold range, the elevator car is considered to have reached the target rectification point, the elevator operation is stopped, and the position indicator is pushed to indicate the vibration non-compliance point corresponding to the target rectification point. It then checks whether a continue running signal is received. If a continue running signal is received, it checks whether the elevator car has reached the last target rectification point. If it has not reached the last target rectification point, the elevator car continues running and checks whether the difference between the cumulative pulse count and the target pulse count corresponding to the next target rectification point is within a preset threshold range. If it is within the threshold range, the elevator car is considered to have reached the target rectification point, the elevator operation is stopped, and the position indicator is pushed to indicate the vibration non-compliance point corresponding to the target rectification point. If the last target rectification point is reached, the elevator stops running. This process is repeated until all target rectification points are reached.

[0074] Furthermore, three information indicator lights 7 displaying different colors are installed on the top of the fixed base 1, namely the first information indicator light, the second information indicator light, and the third information indicator light. The three information indicator lights 7 correspond to the X, Y, and Z directions, respectively, and the different colors of the three information indicator lights 7 facilitate the adjustment personnel to intuitively determine the direction of vibration non-compliance. The information indicator lights 7 can be connected to the elevator control system and controlled to turn on or off through the elevator control system.

[0075] In step S2, the steps of acquiring vibration data during elevator car operation and determining several vibration non-compliance points based on the vibration data include:

[0076] S21. Obtain the first vibration data in the X direction, the second vibration data in the Y direction, and the third vibration data in the Z direction during elevator car operation;

[0077] S22. Based on the first vibration data, determine several vibration non-conforming points and record the vibration information of each vibration non-conforming point as the X direction;

[0078] S23. Based on the second vibration data, determine several vibration non-compliance points and record the vibration information of each vibration non-compliance point as the Y direction;

[0079] S24. Based on the third vibration data, determine several vibration non-compliance points and record the vibration information of each vibration non-compliance point as the Z direction.

[0080] After step S7, which determines that the elevator car has reached the target rectification point and suspends elevator operation, the method further includes:

[0081] S8. Obtain vibration information of the vibration non-compliance points corresponding to the target rectification points reached by the elevator car;

[0082] S9. Determine whether the vibration information is in the X, Y, or Z direction. If the vibration information is in the X direction, turn on the first information indicator light. If the vibration information is in the Y direction, turn on the second information indicator light. If the vibration information is in the Z direction, turn on the third information indicator light.

[0083] In steps S21 to S24 above, vibration data of the elevator car in the X, Y, and Z directions are acquired using an EVA vibration meter and recorded as the first vibration data, the second vibration data, and the third vibration data, respectively. This data is used to obtain the vibration non-compliance dimension of each vibration non-compliance point, indicating whether the non-compliance point is caused by a non-compliance in the X, Y, or Z direction. If the non-compliance point is caused by a non-compliance in the X direction, the vibration information of that point is recorded as the X direction; if it is caused by a non-compliance in the Y direction, the vibration information is recorded as the Y direction; and if it is caused by a non-compliance in the Z direction, the vibration information is recorded as the Z direction.

[0084] In steps S8 and S9 above, different information indicator lights are turned on according to the direction of the non-compliance of the vibration non-compliance point. Specifically, if the vibration non-compliance point is caused by the non-compliance in the X direction, the first information indicator light is turned on; if the vibration non-compliance point is caused by the non-compliance in the Y direction, the second information indicator light is turned on; and if the vibration non-compliance point is caused by the non-compliance in the Z direction, the third information indicator light is turned on. In this way, by turning the three information indicator lights on and off, the direction of the non-compliance of the current vibration non-compliance point is indicated, so that the inspection personnel can intuitively view the vibration information and carry out corresponding inspections.

[0085] In one embodiment, an information box 8 is provided on the top of the fixed base 1, and the information indicator light 7 is L-shaped, including a horizontal part 71 and a vertical part 72. The horizontal part 71 of the information indicator light 7 is located on the top of the information box 8, and the vertical part 72 of the information indicator light 7 is located on one side of the information box 8. This arrangement makes it convenient for the inspectors to observe the information indicator light 7 whether looking down or at eye level.

[0086] Corresponding to the aforementioned embodiments of the elevator vibration detection method of the present invention, the present invention also provides an elevator vibration detection system, including a position indicator device installed on the car top guardrail. The position indicator device includes a fixed base, a clamping mechanism and a position indicator needle. The clamping mechanism is disposed on the fixed base and is used to clamp or loosen the car top guardrail. The position indicator needle is slidably disposed on the top of the fixed base.

[0087] The system includes:
