Abstract
Description
Technical Field

[0002] With the rapid development of high-rise and super high-rise buildings in China, as an efficient vertical transportation tool, the demand for ultra-high speed elevators is increasing. As a safety protection device for preventing the ultra-high speed elevator from falling and descending at an excessive speed, the progressive safety gear must pass the free fall test to complete the formal test certification before it can be put into production and use. When the rated speed of the elevator reaches ultra-high speed, due to the uncertainty of the braking performance of the test safety gear sample, the risk of the free fall test of the safety gear becomes very high: currently, the free fall test of the elevator safety gear generally only relies on the buffer at the bottom of the pit as the last line of protection. If the sample fails to brake and bottoms out, it will cause devastating damage to the test device and the sample, resulting in the inability to continue the test smoothly. Therefore, the lack of a reliable and perfect safety protection method has greatly restricted the development of ultra-high speed elevator safety gears.

[0057] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not used to limit the present application.
[0058] To better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific implementation manners.
[0059] The main solution of the embodiments of the present application is: when the elevator test device performs a free fall test, collect the real-time position signal and real-time speed signal of the test cage; perform speed trigger judgment and height trigger judgment according to the real-time speed signal to obtain a speed judgment result and a height judgment result; generate a safety gear control signal according to the speed judgment result or the height judgment result to control the start state of the electric safety gear.
[0060] In this embodiment, for the convenience of description, the following will be described with the recognition of the ultra-high speed elevator test safety protection device as the execution subject.
[0061] Since the progressive safety gear in the prior art is a safety protection device for preventing the fall and overspeed downward of ultra-high speed elevators, it must pass a free fall test to complete the formal test certification before it can be put into production and use. When the rated speed of the elevator reaches ultra-high speed, due to the uncertainty of the braking performance of the test safety gear sample, the risk of the free fall test of the safety gear becomes very high: currently, the free fall test of the elevator safety gear generally only relies on the pit buffer as the last protection. If the sample fails to brake and bottoms out, it will cause devastating damage to the test device and the sample, resulting in the inability to continue the test smoothly. Therefore, the lack of a reliable and perfect safety protection method has greatly restricted the development of ultra-high speed elevator safety gears.
[0062] The present application provides a solution. By collecting the position and speed of the cage in real time during the free fall test of the elevator test device, and making a dual judgment on whether the safety gear of the elevator test device is effective through the position and speed. When the safety gear is not effective, trigger the electric safety gear brake additionally provided in the elevator test device, effectively avoiding the damage of the elevator test device caused by the failure of the safety gear brake during the test, and being able to fully ensure the test progress.
[0063] As can be seen from the above embodiments, the present application discloses a safety protection method for ultra-high-speed elevator testing: when the elevator testing device performs a free-fall test, the real-time position signal and real-time speed signal of the test cage are collected; speed trigger judgment and height trigger judgment are performed according to the real-time speed signal to obtain a speed judgment result and a height judgment result; a safety gear control signal is generated according to the speed judgment result or the height judgment result to control the starting state of the electrical safety gear; this method collects the position and speed of the cage during the free-fall test of the elevator testing device in real time, and makes a dual judgment on whether the safety gear of the elevator testing device is effective through the position and speed. When the safety gear is not effective, the electrical safety gear provided additionally on the elevator testing device is triggered to brake, effectively avoiding the damage of the elevator testing device caused by the failure of the safety gear to brake during the test, and fully ensuring the test progress.
[0064] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, an ultra-high-speed elevator test safety protection device, etc. that can implement the above functions. Hereinafter, the ultra-high-speed elevator test safety protection device will be taken as an example to illustrate this embodiment and the following embodiments.
[0065] Based on this, an embodiment of the present application provides a safety protection method for ultra-high-speed elevator testing, referring to Figure 1 , Figure 1 is a schematic flowchart of the first embodiment of the safety protection method for ultra-high-speed elevator testing of the present application.
[0066] In this embodiment, the safety protection method for ultra-high-speed elevator testing includes steps S10 to S40:
[0067] Step S10, when the elevator testing device performs a free-fall test, based on the signal acquisition device, collect the real-time position signal and real-time speed signal of the test cage.
[0068] It should be noted that the safety protection method for ultra-high-speed elevator testing is applied to an ultra-high-speed elevator test safety protection system, and the ultra-high-speed elevator test safety protection system includes an elevator testing device, an electrical safety gear, and a signal acquisition device, and the elevator testing device includes a test cage.
[0069] It should be noted that the free-fall test of the elevator progressive safety gear is carried out in the test tower shaft. The test process is as follows: The test cage system is lifted to a certain height, the hook release system is released. When the test cage system (simulating the full-load car mass of the elevator) free-falls to the specified action speed, the test safety gear is lifted and actuated, and the test cage system is stopped on the guide rail. However, when the rated speed of the applied test safety gear reaches ultra-high speed, if the braking force of the test safety gear is insufficient, relying solely on the pit buffer for protection is not enough, which will cause devastating damage to the test device and the sample, resulting in the inability to continue the test smoothly.
[0070] In specific implementation, the schematic diagram of the ultra-high speed elevator test safety protection system can be referred to Figure 2 , Figure 2 The protection safety gear in it, that is, the electrical safety gear in this embodiment, Figure 2 The test tower shaft and the pit floor for carrying out the free-fall test shown in it, which specifically includes a lifting system, a guide rail, a guiding system, a hook release system, a protection safety gear, a test cage system, a position signal acquisition system, a test safety gear, a buffer, and a logic control system. Among them, the position signal acquisition system is associated with the logic control system, and the signals collected by the position signal acquisition system are logically judged by the logic control system to determine whether to trigger the safety protection gear.
[0071] It can be understood that the test cage can be a substitute for the elevator car during the free-fall test, that is, a substitute for the ultra-high speed elevator car, and the test safety gear can be an elevator progressive safety gear.
[0072] It should be understood that the real-time position signal can refer to the real-time position that continuously changes during the free-fall test of the test cage. The real-time position can be obtained by collecting through the position signal acquisition system such as Figure 2 ; The real-time speed signal can be obtained by the position signal system collecting the position change of the test cage at fixed time intervals.
[0073] It should be noted that the acquisition of the real-time position signal can be to set sensors in the test tower shaft as described in Figure 2 . When the test cage passes by the sensor, it can be detected that the test cage has passed, and then the position of the sensor that detects the passing of the cage can be used as the position of the test cage. Similarly, the position interval can be obtained according to the positions of the cage obtained continuously twice, and at the same time, the time interval between the two detections of the cage position can be obtained through the time detection device. The cage speed can be obtained according to the time interval and the position interval.
[0074] Step S20, perform speed trigger judgment according to the real-time speed signal to obtain a speed judgment result, and perform height trigger judgment according to the real-time position signal to obtain a height judgment result.
[0075] It should be noted that the speed trigger judgment can be made by obtaining the descending speed of the test cage based on the real-time speed signal, and the speed judgment result can include normal speed and abnormal speed.
[0076] It should be further noted that the height judgment signal can be obtained by getting the real-time position of the test cage through the real-time position signal, and judging whether the test safety clamp is successfully braked according to the position of the cage. The height judgment result can include abnormal height and normal height.
[0077] It should be understood that the speed judgment is to see whether the speed values corresponding to each height are too fast. If the speed is too fast, there is a risk of failure in the free fall test and the cage crashing to the ground. It is necessary to use the electrical safety clamp for auxiliary braking to protect the safety of the cage.
[0078] It should be understood that when conducting a free fall test on the cage, braking is performed by the test safety clamp. When the braking is successful, the test cage will stop. The height judgment is based on the real-time height to judge whether the test safety clamp of the test cage is successfully braked.
[0079] Step S30, generate a safety clamp control signal according to the speed judgment result or the height judgment result.
[0080] It should be noted that the safety clamp control signal can include a start signal and a hold signal. The start signal can control the electrical safety clamp to brake (such as Figure 2 the protective safety clamp in), and the hold signal can control the electrical safety clamp to maintain the current state without braking.
[0081] It should be noted that the speed trigger judgment and the height trigger judgment are carried out simultaneously.
[0082] In a feasible implementation manner, step S30 can include steps A31~A32:
[0083] Step A31, when the speed judgment result is abnormal speed or the height judgment result is abnormal height, generate a start signal.
[0084] It should be noted that when the speed judgment result is abnormal speed and the height judgment result is abnormal height at high speed, a start signal is also generated.
[0085] It can be understood that the start signal can be generated by the position signal acquisition system and sent to the protective safety clamp. The protective safety clamp can be an electrically controlled safety clamp, and the start signal is used to control the start of the electrical safety clamp.
[0086] It should be understood that the start signal is sent to the electrical safety clamp, and the electrical safety clamp starts to work and brakes the test cage, thus effectively avoiding damage to the test device caused by the test cage bottoming out.
[0087] Step A32, when the speed judgment result is normal speed and the height judgment is normal height, generate a holding signal.
[0088] It can be understood that the holding signal is generated only when the speed judgment result is normal speed and at the same time the height judgment is normal height. The holding signal is also generated by the position signal acquisition system and sent to the electrical safety clamp, and the electrical safety clamp remains in the non-start state.
[0089] It should be understood that the holding signal keeps the electrical safety clamp from braking, avoiding affecting the test effect of the test safety clamp.
[0090] In this embodiment, the protection safety clamp is double-trigger controlled by the speed judgment result and the position judgment result to provide secondary protection for the free fall test of the super-high-speed elevator safety clamp, effectively avoiding damage to the test equipment due to the failure of the test safety clamp test.
[0091] The above is only a feasible implementation manner of step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementation manner of step S30.
[0092] Step S40, control the start state of the electrical safety clamp based on the safety clamp control signal, so that the electrical safety clamp performs safety protection based on the safety clamp control signal.
[0093] It should be noted that the start state includes an activation state and a waiting state. In the activation state, the test cage is braked, and in the waiting state, no braking is performed and it waits to receive the next signal.
[0094] In a feasible implementation manner, step S40 may include steps A41 to A42:
[0095] Step A41, when the safety clamp control signal is the start signal, adjust the start state of the electrical safety clamp to the activation state, and control the electrical safety clamp to brake based on the activation state.
[0096] It should be noted that when the safety clamp control signal is the start signal, an electrical signal is generated based on the start signal; the electrical safety clamp is activated according to the electrical signal, so that the start state of the electrical safety clamp is adjusted to the activation state; when the start state of the electrical safety clamp is the activation state, braking is performed through the electrical safety clamp to achieve safety protection for the elevator test device.
[0097] It should be emphasized that the safety clamp control is through electrical signals rather than direct mechanical control, which can control the space more flexibly and sensitively, respond quickly to braking, and thus brake the test cage in a timely and effective manner.
[0098] Step A42, when the safety gear control signal is the holding signal, adjust the start state of the electric safety gear to the waiting state.
[0099] It can be understood that the control signal of the electric safety gear and the state of the electric safety gear are in one-to-one correspondence, and different states of the electric safety gear correspond to different operations.
[0100] In this embodiment, two situations of the safety gear control signal are used to control the electric safety gear to enter different states. When wanting to start the electric safety gear, it is controlled by an electric signal, which can respond more quickly, cause the electric safety gear to brake, and protect the safety of the test cage equipment.
[0101] The above are only feasible implementation manners of step S40 provided by this embodiment, and this embodiment does not make specific limitations on the specific implementation manner of step S40.
[0102] In specific implementation, an electrically triggered protective safety gear is additionally configured on the test cage system. During the entire free fall test process, the height of the test cage system is monitored in real time through a position signal acquisition system (such as an absolute hoistway position signal sensor, etc.) and transmitted to the logic control system. The logic control system obtains the real-time speed signal through calculation, and at the same time monitors and judges whether there are any abnormalities (reaching the set trigger conditions) in the real-time height and speed of the test cage system. If so, a signal will be output to trigger the action of the protective safety gear, and the protective safety gear will stop the test cage system on the guide rail to achieve the purpose of protecting the test device.
[0103] This embodiment provides a safety protection method for ultra-high-speed elevator testing. By collecting the position and speed of the cage during the free fall test of the elevator test device in real time, it is judged whether the safety gear of the elevator test device is effective through the position and speed. If it is judged that the safety gear is not effective, the electric safety gear additionally provided in the elevator test device is triggered in time, and the electric safety gear is triggered by an electric signal to brake the elevator test device, effectively avoiding the damage of the elevator test device caused by the failure of the safety gear to brake during the test, and being able to fully ensure the test progress.
[0104] Based on the first embodiment of this application, in the second embodiment of this application, the same or similar content as in the above-mentioned embodiment one can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 , step S20 further includes steps S21 to S23:
[0105] Step S21, obtain the real-time speed of the elevator test device according to the real-time speed signal, and obtain the real-time height of the elevator test device according to the real-time position signal.
[0106] It is understandable that the real-time speed can be calculated based on the real-time speed signal generated by the elevator test device. Specifically, the real-time speed of the test cage system can be obtained by differentiating the displacement signal transmitted by the position signal acquisition system.
[0107] It should be understood that the real-time height can be obtained based on the height corresponding to the real-time position signal. For example, the position where the signal is collected can be used as the real-time height corresponding to the real-time position signal.
[0108] Step S22: Determine the reference speed in the first preset curve according to the real-time height, and compare the real-time speed with the reference speed to obtain a speed judgment result. The first preset curve includes a one-to-one corresponding height-speed curve.
[0109] It should be noted that the first reference speed curve is constructed according to the preset braking deceleration parameter; obtain the preset speed redundancy coefficient or preset speed redundancy amount; multiply each speed value in the first reference speed curve by the preset speed redundancy coefficient to obtain the first preset curve, or add the preset speed redundancy amount to each speed value in the first reference speed curve to obtain the first preset curve.
[0110] It should be noted that the first reference speed curve can be the speed curve when the test cage brakes and decelerates with an average deceleration of 0.2g. g is the acceleration due to gravity. The first reference speed curve can include the one-to-one corresponding test cage height and test cage speed.
[0111] It should be emphasized that the preset speed redundancy coefficient and preset speed redundancy amount can be set artificially in advance, where the preset speed redundancy coefficient is greater than 1 and the preset speed redundancy amount is greater than 0.
[0112] It should be noted that the schematic diagram of the first preset curve can be referred to Figure 4 , in accordance with the requirements of the elevator safety technical specifications and standards, the average deceleration during the braking process of the progressive safety gear should be within the range of [0.2g, 1.0g]. Therefore, the protection speed curve "the first preset curve" is set based on the speed curve "the first reference speed curve" when the test cage brakes and decelerates with an average deceleration of 0.2g.
[0113] It should be emphasized that Figure 4 the setting of the first preset curve in
[0114] V2 = k·V1
[0115] where k is the speed redundancy coefficient (k > 1, can be set), V2 represents the first preset curve, V1 represents the first reference speed curve, and k represents the preset speed redundancy coefficient.
[0116] Further, the setting of the first preset curve can also refer to the following formula:
[0117] V2 = V1 + ∆V
[0118] Where, ∆V is the velocity redundancy (∆V > 0, which can be set).
[0119] In a feasible implementation manner, step S22 may include steps A221 to A223:
[0120] Step A221, match the real-time height with the height in the first preset curve, and use the velocity corresponding to the successfully matched height as the reference velocity.
[0121] It can be understood that the real-time height is the height collected by the position signal acquisition system, and the velocity calculated based on this height is used as the real-time velocity.
[0122] It should be understood that the real-time velocity is matched with the velocity of the test cage corresponding one by one in the first preset curve to obtain the reference velocity, or the real-time velocity is substituted into the first preset curve to obtain the reference velocity.
[0123] Step A222, when the real-time velocity is greater than or equal to the reference velocity, regard the velocity anomaly as the velocity judgment result.
[0124] It should be understood that the real-time velocity and the reference velocity are compared. If the real-time velocity is greater than or equal to the reference velocity, it can be considered that the test safety clamp does not play an effective braking role at this time, resulting in the velocity of the test cage being in a relatively fast descending velocity. It is necessary to start the electric safety clamp for auxiliary braking to avoid the test cage hitting the bottom and causing damage to the test cage.
[0125] Step A223, when the real-time velocity is less than the reference velocity, regard the velocity as normal as the velocity judgment result.
[0126] It should be understood that when the real-time velocity is less than the reference velocity, it can be considered that the test safety clamp has performed effective braking at this time, causing the cage for free fall test to stop descending. Then the velocity of the cage decreases, and it can be judged that the velocity is normal.
[0127] In this implementation manner, the real-time velocity signal is obtained through the real-time position signal collected by the position signal acquisition system. Further, the reference velocity corresponding to this position is judged according to the position signal, and whether the real-time velocity at this position is higher than the reference velocity is judged according to the reference velocity, so as to judge whether the velocity is normal. Based on the velocity state, it is judged whether to start the electric cage for auxiliary braking, which can effectively brake the test cage when the test safety clamp fails and avoid damage to the test cage and other test equipment.
[0128] The above is only a feasible implementation manner of step S22 provided in this embodiment, and this embodiment does not specifically limit the specific implementation manner of step S22.
[0129] Step S23: Compare the real-time height with the reference height to obtain a height judgment result.
[0130] It can be understood that the reference height can be the height at which the test safety clamp is activated and finally the test cage is braked and stopped by the safety clamp, or it can be the height at which it is proved that the test safety clamp fails to brake when the test cage is lower than the moving height through testing and empirical setting.
[0131] In specific implementation, the real-time height of the test cage system is monitored according to the displacement signal transmitted by the position signal acquisition system, and then this real-time height signal is compared and judged in real time with the set protection height value (reference height). If a height anomaly (reaching the height trigger condition) occurs, a signal is output to control the protection safety clamp to act for protection.
[0132] In a feasible implementation manner, step S23 may include steps A231 to A233:
[0133] Step A231: Obtain the speed peak value in the second preset curve, and obtain the reference height according to the speed peak value.
[0134] It should be noted that the second preset curve can be the speed curve of braking and decelerating with an average deceleration of 0.2g. The second preset curve can refer to Figure 5 , Figure 5 In the figure, the left broken line represents the second preset curve, the right dotted line represents the reference height, Vmax is the maximum speed during the test, H0 is the initial height of the test cage, H1 is the height after braking and stopping with an average deceleration of 0.2g, and H2 is the set protection height value (i.e., the reference height).
[0135] It should be understood that the speed peak value can be the maximum speed during the test. According to the requirements of the elevator safety technical code and standards, the average deceleration during the braking process of the progressive safety clamp should be within the range of [0.2g, 1.0g] (g is the acceleration of gravity). Therefore, the protection height value H2 is set on the basis of the height value H1 after the test cage decelerates and stops with an average deceleration of 0.2g.
[0136] It should be noted that obtaining the reference height according to the speed peak value can refer to the following formula:
[0137] H2 = H1 - ∆H = H0 - V 2 max / 2 / g - V 2 max / 2 / (0.2g) - ∆H
[0138] Among them, ∆H is the height redundancy, which can be adjusted according to actual requirements, and generally takes a value greater than 0.
[0139] Step A232: When the real-time height is less than or equal to the reference height, the height anomaly is taken as the height judgment result.
[0140] It can be understood that when comparing the real-time height with the reference height, when the reference height is less than or equal to the reference height, it can be understood that the braking of the test safety gear is ineffective at this time, or the braking effect of the test safety gear at this time cannot make the test cage stop safely. The height judgment result at this time is regarded as a height anomaly.
[0141] Step A233: When the real-time height is greater than the reference height, the normal height is taken as the height judgment result.
[0142] It can be understood that when the real-time height is greater than the reference height, it can be temporarily understood that the test safety gear is braking, and it may not be fully effective yet; or it may not have reached the position where the height anomaly can be judged.
[0143] It should be understood that the height trigger judgment and the speed trigger judgment can be carried out in real time. During the free fall test of the test cage, the height and speed are continuously detected, and the height trigger judgment and the speed trigger judgment are continuously carried out. Any abnormal speed judgment or / and abnormal height judgment will trigger the electrical safety gear to brake, and at the same time, an abnormal reminder can also be given.
[0144] In this embodiment, by detecting the height of the test cage in real time and judging whether the real-time height is lower than the lowest protection height of the cage, based on the judgment of the lowest protection height of the cage and the real-time height of the test cage, it can be ensured that when the cage height is lower than the lowest protection height, the electrical safety gear is triggered to perform a protection brake, avoiding damage to the test cage caused by the failure of the test safety gear to brake.
[0145] The above is only a feasible implementation manner of step S23 provided by this embodiment, and this embodiment does not make a specific limitation on the specific implementation manner of step S23.
[0146] This embodiment provides a safety protection method for ultra-high-speed elevator testing. Through the double-trigger mode of the safety gear, the free fall test of the ultra-high-speed elevator safety gear is carried out. Based on the real-time speed of the test device, the whole process of the ultra-high-speed elevator safety gear test is provided with real-time protection throughout the process. Based on the real-time height of the test device, secondary protection is provided before the test device bottoms out, fully and comprehensively ensuring that in the event of failure during the test safety gear test, the electrical safety gear can be started in time for auxiliary braking to ensure the safety of the cage test equipment.
