[0023] The mechanical strength of elevator doors is one of the important guarantees for the safe operation of elevators. In daily use, elevator doors may be subject to various unexpected impacts, such as collisions with passengers, impacts with objects, etc., and in long-term use, they may be affected by frequent door opening and closing operations, environmental factors (such as temperature changes, humidity, etc.) and mechanical stress. Sufficient mechanical strength can ensure that the elevator door will not be deformed, damaged or accidentally opened when impacted, thereby preventing passengers from falling into the shaft, protecting the personal safety of passengers, and ensuring the safe and reliable operation of the elevator. If the mechanical strength of the elevator door is insufficient, it may cause the elevator door to malfunction during operation. If the elevator door cannot be closed or opened normally, it may cause elevator failure, affect the normal use of the elevator, and may even cause safety hazards.

[0024] At present, the static mechanical strength loading test equipment for elevator doors has made certain progress in technical application. However, traditional test equipment can only squeeze a fixed point on the elevator door and cannot flexibly adjust the test point, resulting in incomplete test data. In addition, in the traditional measurement process, due to the obstruction of the test pressure head, the traditional infrared distance detection method cannot accurately measure the distance between the action point and the reference point, so the test accuracy of the entire test equipment is also poor.

[0025] The present invention provides an elevator door testing device 100 .

[0026] See also Figures 1 to 3 In one embodiment of the present invention, the elevator door testing device 100 includes a frame 1 and a testing part 3, the frame 1 includes a movable base 11 and a mounting part, the mounting part is movably mounted on the movable base 11 along the up and down direction, the testing part 3 is mounted on the mounting part, the testing part 3 has an ejection end, and the ejection end has a movement stroke in the horizontal direction, so as to perform a downward pressure test on the elevator door to be tested.

[0027] The structural arrangement in the above-mentioned embodiment is mainly to solve the related problems existing in the existing elevator door testing process. Specifically, after the elevator door is produced, it needs to meet certain mechanical strength tests. Through mechanical strength tests to simulate various unexpected impacts during daily use, to verify whether the mechanical strength of the produced elevator doors can meet the normal use of the elevator, thereby improving the overall quality of the elevator doors. In addition, there are strict testing requirements in the production process of elevator doors. According to the static mechanical strength requirements for elevator doors in Article 5.3.5.3 of GB / T7588.1-2020, when the floor door is in the locked position and the car door is in the closed position, the mechanical strength of all floor doors and their door locks and car doors shall meet the following requirements: First, it can withstand vertical action from any side of the door leaf or door frame at any position and evenly distributed within 5cm 2The static force of 300N on the circular (or square) area of ​​the door shall not exceed 1mm, and the elastic deformation shall not exceed 15mm. After the test, the safety function of the door shall not be affected. Second, it shall be able to withstand any position of the door leaf or door frame acting vertically from the floor station direction or acting vertically from the inside of the car on the door leaf or door frame, and evenly distributed within 100cm 2 A static force of 1000N on a circular (or square) area without any obvious permanent deformation that affects function and safety.

[0028] Most traditional testing methods are conducted manually. During the test, the elevator door to be tested is first fixed by a fixed frame structure, and then the test point is manually loaded by a loading device. Some devices can only squeeze a fixed point during the loading test, and the elevator door test points often need to be set up with multiple points. Therefore, during the use of some traditional test devices, since the measuring point position needs to provide a large downward force, it is often set to a single fixed measuring point. This structure has poor adjustment flexibility, and the convenience during the test process is difficult to meet the requirements, so the test efficiency is generally low. In addition, when loading and pressing, the maximum deformation of the elevator door side wall is located between the pressure head and the elevator door side wall, and the pressure head has a certain area. During the test, due to the obstruction of the test pressure head, the traditional infrared distance detection method cannot accurately measure the distance between the action point and the reference point, so during the measurement process, its accuracy is often difficult to meet the test requirements.

[0029] Considering the above problems, the relevant structures in the above embodiments have the characteristics of flexible adjustment. Specifically, the mobile base 11 can move on the ground, so that the horizontal position of the test part 3 can be adjusted. The mounting part for mounting the test part 3 is movably arranged at the upward end of the mobile base 11, and the mounting part can move in the vertical direction, so that the vertical height of the test part 3 can be adjusted. In the actual test process, the ejection end can be adjusted to correspond to the current test point through the mobile base 11 and the mounting part according to the actual position of the current test point. When the test part 3 is tested, the ejection end can be driven to move in the horizontal direction, so as to load the elevator door with downward pressure. After the test of the current test point is completed, the test part 3 can be adjusted to correspond to the next test point through the mobile base 11 and the mounting part, so that multiple test points on the elevator door can be continuously loaded. Compared with the traditional test method, the above structure is more flexible to adjust and can greatly improve the test efficiency.

[0030] Among them, it can be imagined that the mobile base 11 can be set as a wheel frame structure with a relatively simple structure. That is, a plurality of roller structures are set at the bottom of the frame. In the process of actual position switching and adjustment, the entire frame structure can be pushed to move by manual adjustment, thereby realizing the horizontal movement adjustment of the test part 3. The mobile base 11 can also be set as an electrically driven mobile structure, for example, a corresponding electric control structure and an electric drive structure are set on the mobile frame structure, and the electric drive structure and a plurality of wheel bodies are connected. When the actual adjustment is performed, the corresponding electric control structure can be used to drive the movement of the plurality of wheel bodies, thereby controlling the movement of the entire frame. Regardless of manual adjustment or automatic adjustment, the mobile base 11 can adjust the horizontal position of the test part 3. Its specific structural setting is not specifically limited in this embodiment, and can be designed and selected according to the actual production data.

[0031] Among them, in order to solve the problem that the traditional test structure mentioned above is difficult to accurately obtain the real-time deformation amount of the test point of the elevator door due to the obstruction of the test head. In this embodiment, the deformation amount of the test point of the elevator door is directly reflected by the real-time movement stroke of the ejection end of the test part 3. Specifically, the test part 3 includes a driving member 31, a detection member (not shown in the figure) and a pressure head 32. The driving member 31 includes a driving part 311 and a movable part 312, the driving part 311 is installed on the installation part, the driving part 311 is connected to the movable part 312, so as to drive the movable part 312 to move in the horizontal direction, the detection member is installed on the driving part 311, and is used to detect the movement stroke of the movable part 312 in the horizontal direction, and the pressure head 32 is installed at one end of the movable part 312.

[0032] In the above embodiment, the driving member 31 can drive the pressure head 32 to move in the horizontal direction, so that the pressure head 32 can perform a loading test on the elevator door. During this process, the detection member can synchronously obtain the movement stroke of the pressure head 32 in the horizontal direction. Before the test, one end of the pressure head 32 can be placed close to the point to be tested on the elevator door. At this time, the distance between the side wall of the elevator door and the end of the pressure head 32 is sufficiently small, and there is no interaction force between the two. At this time, this position can be used as the zero point of the test. The movement stroke of the pressure head 32 driven by the driving unit 311 can correspond well to the deformation amount of the point to be tested, so that the problem of inaccurate ranging caused by the pressure head structure blocking the infrared ranging device can be well solved.

[0033] The driving part 311 is specifically configured as a servo motor, which is mounted on the mounting part and includes an encoder structure (not shown in the figure) inside. The rotation parameters of the motor shaft, including the rotation speed and the number of revolutions, can be accurately obtained through the encoder structure. A high-precision ball screw structure (not shown in the figure) is also provided on the mounting part, which is similar to the electric cylinder structure composed of a ball screw. The transmission screw in the ball screw structure is rotatably mounted on the mounting part and connected to the output shaft of the servo motor, and can achieve high-precision rotation under the drive of the servo motor. The nut structure in the ball screw structure is movably mounted on the mounting part in the horizontal direction, and the pressure head 32 is mounted on one end of the nut structure. When the servo motor is working, it can drive the nut structure to achieve horizontal movement through the rotation of the transmission screw, thereby realizing the pressure loading of the pressure head 32. Through the parameters of the screw structure and the actual servo motor shaft. In the above structure, the servo motor is directly connected to the transmission screw, so that the encoder of the servo motor directly feeds back the displacement of the nut structure, reducing the inertia and clearance of the intermediate link, and improving the controllability and control accuracy. The servo motor is integrally connected to the high-precision ball screw structure, which is easy to install, simple to set and convenient to use. In addition, it is conceivable that in order to provide real-time feedback of the pressure information value at the end of the pressure head 32, a columnar force sensor is provided at the end of the pressure head 32. The columnar force sensor has a range of 0N-100kN, an accuracy of 0.5%FS, and is easy to install and has good stability. It is conceivable that in another embodiment of the present invention, the drive unit 311 may be set as a direct drive unit such as a hydraulic or cylinder, but a corresponding monitoring structure needs to be set to detect the stroke of its output end.

[0034] The movement of the mounting portion in the vertical direction is realized by electric drive in this embodiment. Specifically, the mobile base 11 is provided with an adjustment component 2, the adjustment component 2 includes an adjustment mounting seat 21 and a driving structure 22, the adjustment mounting seat 21 is arranged on the mobile base 11, the driving structure 22 includes a driving device 221 and a mounting plate portion 222, the driving device 221 is arranged on the adjustment mounting seat 21, and the driving device 221 is connected to the mounting plate portion 222, so as to drive the mounting plate portion 222 to move in the up and down directions on the adjustment mounting seat 21, wherein the mounting plate portion 222 includes the mounting portion.

[0035] In the present embodiment, when the driving device 221 is working, it can drive the mounting plate 222 to move in the vertical direction, so as to adjust the actual height of the test part 3 on the mounting plate 222. It can be imagined that the driving structure 22 is a linear driving structure 22. Considering that the size of the elevator door in the vertical direction (corresponding to the door height direction) is relatively large during the test, the stroke of the output end of the conventional direct drive structure such as a cylinder or a push rod may not reach the size of the elevator door in the vertical direction. Therefore, in the present embodiment, the driving device 221 is set as a screw motor structure. Specifically, the driving device 221 includes an adjusting motor 2211 and an adjusting screw 2212, the adjusting motor 2211 is installed on the adjusting mounting seat 21, the adjusting screw 2212 is rotatably installed on the adjusting mounting seat 21 in the vertical direction, and the adjusting motor 2211 is connected to the adjusting screw 2212 to drive the adjusting screw 2212 to rotate around the axis in the vertical direction. The adjusting mounting seat 21 is provided with a guide rail structure 212 in the vertical direction, and the mounting plate portion 222 is slidably mounted on the guide rail structure 212, and the mounting plate portion 222 is connected to the adjusting screw rod 2212, so when the adjusting screw rod 2212 rotates, it can drive the mounting plate portion 222 to move in the vertical direction, thereby efficiently adjusting the vertical height of the test portion 3.

[0036] Of course, the structure of the driving device 221 is not unique, and the commonly used cylinder or electric push rod model may not be suitable for the above-mentioned large span adjustment stroke. In another embodiment of the present invention, the driving device 221 can be set to a linear motor structure. The above-mentioned adjustment effect can also be achieved by the linear motor structure, so there is no restriction on the specific structure of the driving device 221, and it can be selected and set according to the actual production data.

[0037] The adjusting motor 2211 drives the mounting plate 222 to move in the vertical direction, so that the pressure head 32 can test the points to be tested at different heights in the vertical direction. The measuring points on the elevator door are within a certain area. In order to prevent the mounting plate 222 from exceeding the limit during the movement, at least two travel switches 4 are provided in the up and down directions of the adjusting mounting seat 21 to limit the movement travel of the mounting plate 222 in the up and down directions. This further ensures the stability of the mounting plate 222 during the movement.

[0038] The adjustment mounting seat 21 is made of welded metal plate structure, and the vertical height of the entire adjustment mounting seat 21 is slightly larger than the actual vertical height of the elevator door. The driving device 221 is installed on the horizontal side of the adjustment mounting seat 21. Considering that if the driving device 221 is directly installed on one side of the side wall of the adjustment mounting seat 21, the entire driving device 221 is protruding from one side of the adjustment mounting seat 21. On the one hand, this exposed installation structure has poor safety during operation, for example, it is easy to damage the driving device 221 due to collision or involvement of debris, or cause injuries to operators; on the other hand, it is not conducive to isolating and protecting the driving device 221. For example, during the operation of the driving device 221, dust and suspended matter in the air are easy to deposit on the driving device 221, making the subsequent maintenance relatively difficult.

[0039] Based on the above problems, in this embodiment, the installation of the driving device 221 is set as a sunken isolation installation method. Specifically, a mounting groove portion 211 is formed at the horizontal end of the adjustment mounting seat 21, and the driving device 221 is at least partially disposed in the mounting groove portion 211. The horizontal end of the mounting plate portion 222 is a connecting end, which is disposed in the mounting groove portion 211 and connected to the driving device 221. Flexible shielding portions 213 are provided between the two ends of the mounting groove portion 211 in the upper and lower directions and the mounting plate portion 222 for shielding part of the structure of the driving device 221.

[0040] In the present embodiment, at least the adjusting screw 2212 is installed in the mounting groove 211, and one end of the mounting plate 222 located in the mounting groove 211 is connected to the adjusting screw 2212. The adjusting motor 2211 is installed at the downward end of the adjusting screw 2212. The mounting groove 211 forms a notch structure at each of the upper and lower end positions of the mounting plate 222. The two notch structures formed can be shielded by the two flexible shielding portions 213, thereby isolating the connecting end of the adjusting screw 2212 and the mounting plate 222 from the outside. And the two shielding structures are flexible structures, which can produce deformation in the vertical direction during the movement of the mounting plate 222 in the vertical direction, and will not affect the movement of the mounting plate 222.

[0041] It is conceivable that the structure of the flexible shielding portion 213 can be set as a shutter structure or a cover cloth structure. When installing, a corresponding guide groove structure can be set inside the opening of the installation groove portion 211, and the horizontal ends of the cover cloth structure can be movably installed in the guide groove through multiple sliders, so as to achieve the above-mentioned shielding effect, and will not affect the movement of the installation plate portion 222. The above-mentioned shielding structure is not specifically limited and can be set according to actual conditions.

[0042] In addition, in order to facilitate the movement of the entire structure, a moving handle 6 is also provided on the adjustment mounting seat 21 to assist the movement of the moving base 11, and a display device 5 is also provided on the adjustment mounting seat 21, and the display device 5 is used to display test data and image information. In actual use, the test section 3 can synchronously feed back the real-time displacement and real-time pressure of the pressure head 32 to the display device 5, and the display device 5 is provided with a corresponding analysis element, which can analyze and process the relevant data, so as to output the acquired data information to the outside in the form of a chart. This allows people to more intuitively see the changes in the relationship between the deformation amount of the test point and the downward pressure.

[0043] like Figures 4 to 6 The present invention also provides an elevator door testing method, which is applied to an elevator door testing device 100. The specific structure of the elevator door testing device 100 is as described in the above embodiment. Please refer to Figures 1 to 3 Because the elevator door testing device 100 applies all the technical solutions in the above implementation, it has all the beneficial effects in the above embodiments, which will not be described here one by one.

[0044] The elevator door test control method comprises the following test steps: Get preset loading parameters; Before testing, it is necessary to confirm the model and specifications of the elevator door to be tested, and then input the control data required for the test into the device through input devices, including keyboards and touch screens. The control terminal in the device first needs to obtain the input data information to form the preset loading parameters.

[0045] The position of the pressure head portion 32 on the testing portion 3 is adjusted so that the pressure head portion 32 corresponds to the target point to be tested on the elevator door to be tested, and a test zero point is obtained.

[0046] When conducting the test, the elevator door to be tested needs to be fixed on the test frame first. After the elevator door to be tested is fixed in a vertical position, the spatial position information of the target point to be tested on the elevator door to be tested is obtained, specifically including the horizontal coordinate position and vertical coordinate position of the target point to be tested.

[0047] The movable base 11 and the driving device 221 for driving the testing part 3 to move are controlled to adjust the horizontal position and the height position of the pressing head part 32 respectively, so that one end of the pressing head part 32 corresponds to the target point to be tested.

[0048] The mobile base 11 can be pushed by manual movement to move the mobile base 11 to the test end side of the elevator door to be tested, and the horizontal position of the output end of the test unit 3 corresponds to the horizontal position of the target point to be tested. After the horizontal position of the mobile base 11 is adjusted, the adjustment motor 2211 in the drive device 221 drives the adjustment screw 2212 to rotate, and then the specific vertical height of the mounting plate 222 is adjusted, so that the pressure head 32 at the end of the test unit 3 is located at the positive side position of the target point to be tested.

[0049] In the above adjustment process, in addition to manually adjusting the position of the mobile base 11, the mobile base 11 and the driving device 221 can also be set as an automatic adjustment component 2. Specifically, the mobile base 11 can be set as an electrically driven mobile structure, and a corresponding visual sensing structure can be installed on the vertical mounting seat. The position of the point to be tested can be marked on the elevator door to be tested in a different color. During the automatic adjustment process, the visual sensing structure can obtain the coordinate information of the target point to be tested, and then the corresponding electric driving structure 22 is driven by the control device to drive the mobile base 11 and the mounting plate part 222 to move, thereby automatically adjusting the test part 3 to the lateral position of the target point to be tested.

[0050] At the same time, in order to ensure the accuracy of the test data, it is necessary to adjust the end of the pressure head 32 to be in contact with the side wall box of the target point to be measured. Specifically, it is necessary to control the driving member 31 used to drive the pressure head 32 to move horizontally, so that one end of the pressure head 32 is in contact with the target point to be measured.

[0051] The coordinate position where the pressure head 32 and the elevator door to be tested are attached is used as the test zero point. When the pressure head 32 presses down the target point to be tested to deform the elevator door to be tested, the horizontal displacement of the pressure head 32 can accurately correspond to the actual deformation of the target point to be tested.

[0052] Generally speaking, the same elevator door to be tested contains multiple test points. Through the above test method, after the test is completed at one test point, the test part 3 can be quickly transferred to the next test point position, so as to achieve rapid switching between the test points. Compared with the traditional test method, the test efficiency can be improved by 300% (single test time is shortened from 30 minutes to 10 minutes) through the above test method, and the loading accuracy reaches 0.3% FS (better than the national standard 1%), and the maximum deformation of the door panel can be detected to be 0.05mm (existing equipment is 0.2mm).

[0053] After the above adjustment process is completed, the pressure head portion 32 is controlled to pressurize the target point to be measured with the preset loading parameters, and the real-time displacement of the pressure head portion 32 is obtained.

[0054] Through the above structural setting, it can be known that the real-time displacement of the pressure head 32 can correspond to the real-time deformation of the target point to be measured, so during the test, the actual displacement of the pressure head 32 under the corresponding pressure can be corresponded to form a corresponding mapping relationship.

[0055] Specifically, the real-time displacement and the preset loading parameter can be associated and output in the form of a chart, which can clearly show the deformation magnitude of the target point to be measured under the corresponding pressure value.

[0056] Wherein, the preset loading parameters include a preset holding time and a target loading force. Before associating the real-time displacement with the preset loading parameters and outputting them in the form of a chart, it also includes controlling the pressure head 32 to perform a holding operation with the target loading force according to the preset holding time. The loading force during the downward pressure process is loaded from zero at the zero position. Wherein, the preset loading parameters include a unit loading increase value and a target loading force. During the loading process, the downward pressure is increased sequentially from the zero position with a certain unit loading increase value. When the cumulative amount of the downward pressure reaches the target loading force, the pressurization of the target point to be tested is stopped. At this time, a holding pressure operation is also required to determine the amount of permanent deformation caused. Specifically, a preset holding pressure time period will be set. When the cumulative pressure reaches the target loading force, the above-mentioned holding pressure operation will be performed within the holding pressure time period. Usually, in order to ensure the test efficiency, the holding pressure time T will be set. i Set it between 4min and 6min.

[0057] In order to ensure the stability of the loading value of the unit load increase during the loading process, the unit load increase will be corrected in real time during the loading process. Specifically, the preset loading parameters include the initial loading force and the unit load increase. When the downward force is continuously loaded with a fixed pressure, it is necessary to calculate the deviation information between the unit load increase and the actual unit load increase, and then input the deviation information into the preset proportional-integral-differential controller to obtain the control signal output by the preset proportional-integral-differential controller. The output control signal includes the deviation of the actual loading force. During the actual loading process, if the actual load is not reached at the current loading speed, the corresponding control device will adjust the unit load increase based on the control signal. In this way, the unit load increase is kept in a stable loading state, thereby ensuring the accuracy and credibility of the test data during the test process.
