Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

At present, the landing door of the elevator is most likely to rely on force, artificially kicking the door and other phenomena. If the engagement depth of the elevator landing door lock is shallow, it is easy to cause dangerous situations such as abnormal opening of the landing door lock when the above-mentioned human phenomena occur. . Therefore, the standard stipulates that at the critical point when the electrical safety circuit of the landing door lock is closed and the elevator can run, the engagement depth of the door lock when the elevator landing door or car door is closed must be greater than 7mm, that is, the mechanical locking elements (such as lock hooks, latches) must be at least Engage or hook firmly 7mm, the elevator car can run normally.

In order to ensure the safety of the elevator car operation, it is necessary to detect the engagement depth of the elevator door lock, based on two aspects, one is to find the critical point when the contact of the electrical safety device just contacts, and the other is to measure the lock hook at the critical point The length overlapping with the hook block is the engagement depth of the door lock.

At present, the methods for judging the critical point of door lock engagement mainly include spark method, sound method, trial operation, voltage method and so on.

Among them, the spark method is to judge the critical point of engagement of the locking element by observing the arc spark generated when the locking element is in the process of slowly closing and just touching the contact of the electrical safety device, keeping the locking element in this critical state, and then Use a steel ruler to measure the shackle engagement length. This method is suitable for door locks that are prone to arc sparks when the contacts are closed.

The sound method is to slowly close the locking element to make the electrical contacts just contact, and judge the critical point of the door lock engagement by listening to the sound of the contactor in the control cabinet, so as to measure the engagement length. This method is suitable for the inspection of door locks of elevators at low floors or floors near the control cabinet.

The test run is to keep pressing the maintenance down button during the process of slowly closing the door lock. When the car just starts to move, it is the critical point of door lock engagement, and the engagement length at this time is measured. This method is suitable for any elevator and door lock engagement inspection of any landing, but it often has hysteresis and it is difficult to obtain an accurate critical point.

The voltage method is to select the voltage range through the multimeter, and connect the two wires of the multimeter with the two electrical contacts of the door lock. At this time, the reading of the multimeter is a certain constant value V, and the locking element is slowly closed. When the reading of the multimeter changes from the constant value V When the sudden change is close to zero value, it is the critical point of door lock engagement. This method is more accurate in judging the critical point of meshing, but it is a little troublesome to check.

Because in the actual elevator space, the door lock is installed on the top sill of the elevator landing door, the door sill itself is a U-shaped bottom plate, the U-shaped bottom is installed on the shaft wall, and the upper and lower guard plates are formed on both sides of the U-shaped. Opposite the door sill is the running car door, and the space available in the up-down direction and front-back direction of the door lock is very small. Therefore, it is impossible to automatically detect the engagement depth by setting measuring instruments around the door lock. The current traditional measurement Methods include visual inspection, steel ruler or vernier caliper measurement method, feeler gauge measurement method, etc. Generally, workers are required to stand on the top of the car for detection, and the normal operation of the elevator needs to be stopped, which is inefficient, requires a large number of detection personnel, takes a long time for detection, and the detection results are greatly affected by the detection personnel, and the accuracy is low.

Based on this, an elevator door lock engagement depth detector provided by the embodiment of the present invention can obtain the engagement depth by measuring the angle through the detachable sensor when the electrical contacts are closed, and can quickly detect the engagement depth of the door lock without stopping the operation of the elevator. Higher precision.

The following is a detailed description through examples.

Fig. 1 is a schematic structural diagram of an elevator door lock engagement depth detector provided by an embodiment of the present invention, which is used in the field of elevator door lock safety detection to detect the door lock engagement depth between the door lock seat and the door lock hook, as shown in Fig. 1 , Including an angle sensor 100, an acceleration sensor 200 and a processor;

The acceleration sensor 200 is detachably arranged on the electrical contact arm 302 of the door lock seat 300 of the elevator door lock, and is used to collect the acceleration signal when the electrical contact is closed, and send the acceleration signal to the angle sensor 100;

The angle sensor 100 is detachably arranged on the rotating arm 401 of the door lock hook 400 of the elevator door lock, and is used to measure the first angle formed by the rotating arm 401 and the horizontal plane in real time, and when the acceleration signal is received, the measured angle is obtained the second angle formed by the rotating arm 401 and the horizontal plane, and sending the first angle and the second angle to the processor;

The processor is configured to receive the first angle and the second angle, and obtain the engagement depth of the door lock hook 400 and the door lock seat 300 .

In a preferred embodiment of practical application, when the electrical contacts are closed, the acceleration signal is collected by the acceleration sensor 200 to determine the critical point of the door lock engagement, and the angle sensor 100 will collect the real-time formed by the door lock hook 400 rotating arm 401 and the horizontal plane. The first angle and the second angle collected when the acceleration signal is received are sent to the processor, so that the processor can calculate the engagement depth of the door lock hook 400 and the door lock seat 300 . Among them, the detachable acceleration sensor 200 and angle sensor 100 are installed on the door lock without affecting the operation of the elevator, so that the depth of engagement of the door lock can be quickly detected without stopping the normal operation of the elevator, which can ensure the safety of the general elevator door lock. The detection is carried out without being affected by the detection personnel, and the accuracy is high.

It should be noted that, in the embodiment of the present invention, the critical point of closing the electric safety circuit of the door lock is determined by detecting the acceleration signal when the electrical contact arm 302 vibrates, and the angle sensor 100 is used to measure the angle when the door lock hook 400 and the critical point are measured. The overlapping length (engagement depth) of the hook blocks 301 of the door lock seat 300 . By adopting the detachable acceleration sensor 200 and angle sensor 100 arranged on the door lock, the engagement depth of the door lock can be directly detected at the elevator stop without affecting the normal operation of the elevator, and a single detection worker can complete the measurement. Improve the safety of the elevator door lock detection process, improve work efficiency, and at the same time, high precision, avoid the situation of insufficient measurement accuracy caused by elevator outage and observation errors in detection work.

In actual elevator applications, since the elevator door lock is an important part of the elevator, it is often installed at the top sill of the elevator landing door, and the space at the top sill is relatively small, so it is impossible to install detection equipment around the door lock. This application selects the highly integrated angle sensor 100 and acceleration sensor 200 to be detachably installed on the door lock, which can well meet the requirements of high-precision automatic measurement, and at the same time is small in size, easy to install, easy to operate, and greatly improves the detection efficiency and detection efficiency. precision.

As an optional embodiment, the detection staff does not need to terminate the elevator work. When the elevator landing door is opened and docked, they can enter the elevator to complete the installation of the angle sensor 100 and the acceleration sensor 200, and when the elevator landing door is closed , after measuring the engagement depth, the angle sensor 100 and the acceleration sensor 200 are unloaded to complete the detection of the engagement depth of the elevator landing door locks on this floor.

In an optional embodiment, the processor includes a hand-held smart terminal such as a hand-held data processor, which is convenient for detecting the carrying and movement of the staff.

In some possible preferred embodiments, the angle sensor 100 may include a high-frequency and high-precision inclination sensor, a multi-serial port MCU, a clock, a memory, a Bluetooth and WIFI module, a battery, and other devices to complete the detection of the acceleration signal when the electrical safety circuit of the door lock is closed. Receive and collect angle signals. The acceleration sensor 200 includes components such as a micro serial acceleration module, a WIFI module and a battery, and is used to collect the acceleration signal of the electrical contact arm 302 during the closing process of the elevator door lock and send it to the angle sensor 100 . The data transmission between the angle sensor 100 and the handheld data processor can be carried out by means of bluetooth communication.

It can be understood that the above-mentioned internal device composition of the angle sensor 100 and the acceleration sensor 200 is only an exemplary embodiment, and the component structure that can realize the functions of the above-mentioned angle sensor 100 and the acceleration sensor 200 can complete the embodiment of the present invention, here The device composition and internal device connections of the angle sensor 100 and the acceleration sensor 200 are not specifically limited, and those skilled in the art can know.

In order to further realize the purpose that the acceleration sensor 200 and the angle sensor 100 are detachably arranged on the elevator door lock, in an optional embodiment, the detector also includes a suction assembly, which is respectively arranged on the acceleration sensor 200 and the angle sensor 100 for use The acceleration sensor 200 and the angle sensor 100 are detachably attached to the electrical contact arm 302 and the rotating arm 401 respectively.

As an optional embodiment, the suction assembly includes a fixed component and a magnetic component;

The fixing component is connected with the acceleration sensor 200 and the angle sensor 100 respectively, and is used to detachably arrange the magnetic component on the acceleration sensor 200 and the angle sensor 100 respectively.

Here, the elevator door lock is generally made of metal, which can be absorbed by magnetic substances. In the embodiment of the present invention, the magnetic components are respectively arranged on the acceleration sensor 200 and the angle sensor 100 through the fixing components, and then the acceleration sensor 200 and the angle sensor 100 are connected by the magnetic components. The sensor 100 is fixed with the elevator door lock. Wherein, the fixing component may include a fixing sleeve matching the size of the acceleration sensor 200 and the angle sensor 100 respectively, and is sleeved on the acceleration sensor 200 and the angle sensor 100 to fix the magnetic component.

As shown in FIG. 2 and FIG. 3 , the opening and closing action of the door lock is realized by the door operator driving the door knife 500 , and then driving the door lock roller 501 . The closing and locking of the elevator landing door not only depends on the door closing drive of the door machine and the mechanical locking of the door lock hook 400 and door lock seat 300, but also depends on the electrical safety device for verification. The combination of the two forms a complete Electromechanical door locking device. The door lock hook 400 approaches the door lock seat 300 along the slope of the hook block 301, reaches the inner side of the hook block 301 and sinks to form a mechanical lock; the conductive piece 402 in the door lock hook 400 touches the electrical contact in the door lock seat 300 The arm 302 forms an electrical safety loop closure, and the elevator door lock is closed through the process of mechanical locking and electrical safety loop closure.

During the closing process of the door lock, the door lock hook 400 driven by the rotating arm 401 rotates at a small angle with the door lock roller 501 as the center of the circle. When the rotation reaches a certain degree, the conductive sheet 402 collides with the electrical contact arm 302 to conduct the electrical safety circuit. , the collision conduction causes the electrical contact arm 302 to vibrate, generating an acceleration. The embodiment of the present invention obtains the critical point signal of the electrical circuit closure of the door lock through the acceleration signal when the electrical contact arm 302 vibrates. The lock's engagement depth.

It can be understood that the electrical contact arm 302 is always in a static state during the closing process of the elevator door lock, with constant speed and zero acceleration, until the conductive sheet 402 collides with the electrical contact arm 302 at the instant when the door lock is closed. The acceleration sensor 200 collects the acceleration signal and sends it to the angle sensor 100. When the angle sensor 100 receives the acceleration signal, it automatically stops detecting the angle signal, and simultaneously transmits the angle signal when it stops and the angle signal collected in real time before stopping to the handheld data processor. . The handheld data processor automatically calculates the engagement depth of the door lock based on the received angle signal. As an optional embodiment, the handheld data processor includes a display screen, an input device, a memory, a communication module and a printing module, which can display, store, print and upload the detection process data and detection results. Here, the input device includes a keyboard and a touch screen.

In the actual measurement process, the length of the rotating arm 401 of the door lock hook 400 is set in the handheld data processor in advance. For the elevator door lock detected for the first time, the length of the rotating arm 401 of the door lock needs to be calibrated and measured. In an optional embodiment, the door lock seat 300 includes a hook block 301 for engaging with the door lock hook 400, and the tester also includes a standard block 600, which is detachably arranged on the door lock seat 300 for calibrating the door lock. The length of the rotating arm 401 of the locking hook 400 . Wherein, the length of the rotating arm 401 is shown in FIG. 2 .

As shown in Figure 4, in an optional embodiment, a standard block 600 is used for calibration and calibration, and the standard block 600 includes a mounting base 603, an adjustment rod 602 and a calibration block 601, and the mounting base 603 is detachably arranged on the door lock seat 300 , the calibration block 601 is connected to the mounting base 603 through the adjustment rod 602;

The adjustment rod 602 is used to adjust the height of the calibration block 601 so that the calibration block 601 , the door lock hook 400 and the hook block 301 abut against each other.

In order to ensure the stability and reliability of the abutment of the calibration block 601, the door lock hook 400 and the hook block 301, as an optional implementation, the lower surface of the calibration block 601 also includes an abutment block 605, through which the abutment block 605 and the hook The abutting relationship of the block 301 ensures that the abutment effect of the calibration block 601, the door lock hook 400 and the hook block 301 is more stable, and the measured value is more accurate.

Here, the shape of the standard block 600 is not specifically limited, and FIG. 4 can be used as a preferred embodiment.

Wherein, as shown in Figures 4 and 5, the calibration block in the standard block is a stepped block with a fixed height difference, and a circular groove 604 is arranged inside the calibration block, and the height of the calibration block is consistent with the thickness of the circular groove 604, both Preset fixed height H, such as 3mm, 5mm, etc., place the standard block on the inner side of the door lock hook, and when the door lock hook is stuck on the step of the calibration block in the standard block (the upper surface of the calibration block) and under the step (circle When the bottom surface of the groove 604, that is, the lower surface of the calibration block), the angle sensor measures the angle twice to obtain the angle difference A.

Here, the height difference of the calibration block is H, and the angle difference corresponding to the height difference of the calibration block is A, then 2πL/360*A=H, that is, L=H*360/2πA, where L is the length of the rotating arm. It can be understood that the change in angle (angle difference) in this process is very small, so the difference between the arc length and the chord length can be ignored, and they are approximately considered equal, that is, the height difference (chord length) of the calibration block is used as the approximate angle difference The arc length corresponding to A.

The handheld data processor calculates the length L of the rotating arm of the elevator door lock according to the height difference H of the calibration block, and the angle difference A measured by the angle sensor when the calibration block, the door lock hook and the hook block abut against each other, and performs record storage.

In order to realize the detection of the engagement depth more accurately, as a static engagement depth calculation method, the angle change of the calibration block with a fixed height during the closing process of the door lock can also be combined to obtain the angle signal of the door lock engagement, and then obtain the door lock Engagement depth.

Here, the angle sensor is also used to send the measured third angle signal to the processor under the condition that the calibration block, the door lock hook and the hook block abut against each other.

The processor is also used for receiving the second angle and the third angle, and calculating the engagement depth between the door lock hook and the door lock seat.

Wherein, the handheld data processor receives from the angle sensor the third angle when the door lock hook abuts against the hook stopper, the second angle when receiving the acceleration signal to terminate the detection, and the preset length L of the door lock rotating arm , the meshing depth between the door lock hook and the hook stopper in the door lock seat is calculated through the geometric relationship, and the specific calculation method can refer to the dynamic calculation method of the meshing depth.

As shown in FIG. 6 , here, as a dynamic calculation method of the engagement depth, the embodiment of the present invention calculates the engagement depth of the door lock according to the angle variation. Since the length of the rotating arm is known, the calculation is simple.

Suppose the angle at which the door lock hook reaches the highest point is α. This angle is the maximum angle during the closing process of the door lock (select the angle with the largest angle with the horizontal plane in the first angle), and the angle of the critical point of door lock closing (the second angle) is β, then the door lock engagement depth D≈L(sinα-sinβ).

It should be noted that the angle of the rotating arm and the angle of the angle sensor will be slightly different due to installation reasons, and the deviation angle between the angle of the rotating arm and the angle of the angle sensor is used Indicates that it is approximately ignored because the deviation angle is small, that is, the engagement depth of the door lock is:

here, because small so That is, D≈L(sinα-sinβ).

In the actual measurement process, the testing staff generally adopt the following measurement process:

1) Press the elevator floor key to drive the elevator to the landing where the inspector is located. After the landing door is opened, the inspector enters the elevator car, and at the same time, use an obstacle to prevent the door from closing or press the door open button to prevent the door from closing;

2) Adsorb the angle sensor on the door lock hook, basically parallel to the rotating arm of the door lock hook, turn on the power switch of the angle sensor; attach the acceleration sensor to the electrical contact arm, turn on the power switch of the acceleration sensor; start the handheld data The processor detection software starts the measurement.

3) Remove the obstacle or release the door open button to make the door lock automatically close, and start measuring the engagement depth of the door lock;

4) Multiple measurement results can be obtained by repeatedly opening and closing the door.

5) After the measurement is completed, remove the angle sensor and the acceleration sensor to complete the detection of the engagement depth of the door lock on this layer.

6) According to the other floors of the elevator, repeat the above steps to complete the detection of the engagement depth of the door locks of other floors.

Further, an embodiment of the present invention also provides an elevator system, including the above-mentioned elevator door lock engagement depth detector and an elevator body, the elevator body includes at least one, and the door lock engagement depth detector can be installed inside each elevator body, The inspection staff can inspect each elevator by carrying a processor, or multiple inspection staff can inspect each elevator within the scope of duty by carrying the processor corresponding to the elevator they belong to.
