Description

[0002] The national standard "Elevator Technical Requirements" clearly stipulates the opening and closing times for elevators with different door opening widths, requiring that the opening and closing times should not exceed specific values. The car door's operating speed during opening and closing directly affects operating efficiency, comfort, and safety. A balance needs to be struck between rapid passage and anti-pinch protection, avoiding door collision noise and vibration at the end of closing. After the installation of a new elevator, the opening and closing times need to be verified for compliance, confirming the rationality of the door operator control program and ensuring a smooth transition between acceleration and deceleration phases; it should neither generate impact vibrations nor affect door opening and closing efficiency.

[0039] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Please see Figures 1 to 3 This embodiment discloses an elevator door opening and closing time and speed measuring device, including a measuring terminal 100, a speed measuring module 200, and a bracket 300. The measuring terminal 100 includes a housing 110, an encoder socket 120, and a button trigger switch 150. The encoder socket 120 and the button trigger switch 150 are both mounted on the housing 110, and the button trigger switch 150 is used to press the elevator door opening and closing button. The speed measuring module 200 includes a suction cup 210, a suction cup latch 220, a roller 230, and a rotary encoder 240. The suction cup latch 220 is mounted on the suction cup 210. The roller 230 is coaxially connected to the rotary encoder 240, and the rotary encoder 240 is electrically connected to the encoder socket 120. The bracket 300 is composed of multiple bracket arms connected one by one. The first end of the bracket 300 is movably connected to the suction cup 210, and the second end of the bracket 300 is equipped with the roller 230 and the rotary encoder 240.

[0041] The housing 110 provides space for other components, including the encoder socket 120 and the push-button trigger switch 150. The encoder socket 120 connects to the rotary encoder 240 for signal transmission. The push-button trigger switch 150 is used to press the open / close button 431 or the close button 432, precisely triggering the recording of the elevator door opening / closing time. A suction cup 210 is used to attach the speed measuring module 200 to the elevator button panel 430, and a suction cup latch 220 ensures a secure attachment. A roller 230 is coaxially connected to the rotary encoder 240. When the elevator door opens or closes, the roller 230 rolls, causing the rotary encoder 240 to rotate, thus recording the speed of the elevator door opening / closing. The rotary encoder 240 is electrically connected to the encoder socket 120, transmitting the recorded data to the measurement terminal 100 for data processing. The bracket 300 consists of multiple bracket arms. The first end of the bracket 300 is connected to the suction cup 210, and the second end of the bracket 300 is equipped with a roller 230 and a rotary encoder 240. This allows it to adapt to different elevator door sizes and installation environments, ensuring the speed measuring module 200 operates normally when the elevator car door opens and closes. When the elevator car door opens or closes, the suction cup 210 and the bracket 300 are fixed to the door. The roller 230 rolls under the movement of the elevator car door, driving the rotary encoder 240 to rotate. Data is transmitted to the measurement terminal 100 through the encoder socket 120, recording the speed during the opening and closing of the elevator car door, thus achieving accurate measurement of the elevator door opening and closing time and speed.

[0042] Please see Figure 3 A processor 130 is housed inside the housing 110, and the processor 130 is electrically connected to the rotary encoder 240. The processor 130 receives and processes electrical signals from the rotary encoder 240 to achieve precise monitoring of the elevator door opening and closing. The rotary encoder 240 detects the rotational speed of the roller 230, converting the physical rotation signal into an electrical signal and transmitting it to the processor 130. After detecting the rotational information of the roller 230, the rotary encoder 240 converts it into an electrical signal and sends it to the processor 130. The processor 130 processes the received electrical signal to achieve precise monitoring of the elevator door opening and closing.

[0043] Please see Figure 2 and Figure 3A display screen 140 is mounted on the housing 110. The display screen 140 is electrically connected to the processor 130 and is used to display elevator door opening and closing measurement data. The processor 130 is responsible for collecting and processing real-time data on elevator door opening and closing, and finally displaying the measurement results on the display screen 140. During elevator operation, the rotary encoder 240 collects relevant data on door opening and closing and transmits it to the processor 130. The processor 130 processes the data and presents the processing results through the display screen 140, so that the operator can intuitively obtain the measurement information of elevator door opening and closing.

[0044] Please see Figure 2 and Figure 3 The measurement terminal 100 is also equipped with a power on / off button 160, which is electrically connected to the processor 130. The measurement terminal 100 is also equipped with a charging interface 180, which is connected to a battery, which is installed inside the housing 110.

[0045] Please see Figure 2 and Figure 3 The measurement terminal 100 also has a built-in wireless communication module 170, which is electrically connected to the processor 130. The wireless communication module 170 uses Bluetooth or Wi-Fi communication. This connection allows the processor 130 to communicate with external devices, enhancing the convenience and flexibility of the measurement terminal 100. The measurement terminal 100 establishes a connection with external devices through the built-in wireless communication module 170. After processing the measurement data, the processor 130 sends the data out through the wireless communication module 170 and can also receive data from external devices, achieving bidirectional data transmission and improving system integration.

[0046] Please refer to Figure 1 The rotary encoder 240 is connected to the encoder socket 120 via a communication cable. The rotary encoder 240 detects and outputs the angle and speed information of the roller 230, achieving precise position and speed feedback; the encoder socket 120 provides a connection interface for the rotary encoder 240. When the rotary encoder 240 is connected to the encoder socket 120 via the communication cable, the rotation angle and speed data detected by the rotary encoder 240 are transmitted to the processor 130 in real time. The rotary encoder 240 detects changes in the speed of the rotating shaft and converts them into electrical signals, which are transmitted to the encoder socket 120 via the communication cable. The processor 130 processes and responds to these signals, thereby measuring the elevator door opening and closing speed.

[0047] Please see Figure 4The support 300 includes a first support arm 310, a second support arm 320, and a third support arm 330. The first end of the first support arm 310 is movably connected to the suction cup 210, the second end of the first support arm 310 is movably connected to the first end of the second support arm 320, and the first end of the third support arm 330 is movably connected to the second end of the second support arm 320. A roller 230 and a rotary encoder 240 are mounted on the second end of the third support arm 330. The first support arm 310 is movably connected to the suction cup 210; the second support arm 320 serves as an intermediate connector, connecting the first support arm 310 and the third support arm 330, and functions to transmit support force and adjust position; the third support arm 330 is equipped with the roller 230 and the rotary encoder 240, providing support and fixation. Before measurement, attach the suction cup 210 to the elevator button panel 430, adjust the fastening knob 312 so that the rolling surface of the roller 230 is on the same plane as the door panel of the first elevator door 410, and adjust the roller 230 to the side close to the elevator button panel 430.

[0048] Please see Figure 5 and Figure 6 Both ends of the first support arm 310 and the second support arm 320 are provided with through holes 311, and fastening knobs 312 are inserted into the through holes 311. The first support arm 310 and the second support arm 320 are connected through the through holes 311 at both ends, and are fixed and adjusted by the fastening knobs 312, which makes the installation and disassembly operations convenient, while ensuring the reliability and flexibility of the connection.

[0049] Please see Figure 5 and Figure 6 The first end of the third support arm 330 is provided with a through hole 311, into which a fastening knob 312 is inserted. The second end of the third support arm 330 is provided with a mounting hole 331, into which the rotary encoder 240 is inserted. The first end of the third support arm 330 is connected to the second support arm 320 through the through hole 311, fixing the position of the third support arm 330 and ensuring its stability. The second end of the third support arm 330 is connected to the rotary encoder 240 through the mounting hole 331, allowing the roller 230 and the rotary encoder 240 to be flexibly installed and moved.

[0050] Please see Figure 7The elevator door opening time and speed are measured. Before measurement, suction cup 210 is attached to the elevator button panel 430, and fastening knob 312 is adjusted so that the rolling surface of roller 230 is on the same plane as the door surface of the first elevator door 410, and roller 230 is adjusted to be close to the side of the elevator button panel 430. Before measurement, the first elevator door 410 and the first elevator door 420 are in the closed state. The door opening button 431 is pressed by the button trigger switch 150, and the measuring terminal 100 records the instant t1 of the button trigger switch action, which is the start of door opening. The door begins to close gradually, driving roller 230 to roll, and the door opening speed is continuously measured. When the elevator door ends, the door surface of the first elevator door 410 loses contact with roller 230, roller 230 stops rotating, and the door speed is zero. The measuring terminal 100 records the running speed of the first elevator door 410 throughout the entire elevator door opening process. The processor 130 analyzes the speed data sequence to determine the moment t2 when the speed of the first elevator door 410 is zero, and measures the door opening time as t2 - t1. During the measurement process, the display screen 140 dynamically refreshes and displays the elevator door opening speed curve, and allows users to view the speed curves and data from previous measurements.

[0051] Please see Figure 8 The elevator door closing time and closing speed were measured. Before measurement, the suction cup 210 was attached to the elevator button panel 430, and the fastening knob 312 was adjusted so that the rolling surface of the roller 230 was on the same plane as the door surface of the first elevator door 410, and the roller 230 was adjusted to be close to the side of the elevator button panel 430. Before measurement, the first elevator door 410 and the first elevator door 420 were in the open state. The door closing button 432 was pressed by the button trigger switch 150, and the measurement terminal 100 recorded the instant t3 when the button trigger switch was activated. t3 is the moment when the door begins to close. Subsequently, the first elevator door 410 contacts the rolling surface of the roller 230, and the closing speed is collected to record the door's running speed throughout the entire closing process. Then, the first elevator door 410 gradually opens, causing the roller 230 to roll, and the closing speed is continuously measured. When both the first elevator door 410 and the first elevator door 420 are completely closed, the roller 230 stops rotating, indicating that the door is fully closed. The processor 130 analyzes the speed data sequence to determine the moment t4 when the speed of the first elevator door 410 drops to zero at the end of the closing process, thus measuring the closing time as t4 - t3. During the measurement process, the display screen 140 dynamically refreshes and displays the elevator closing speed curve, and allows users to view previous speed measurement curves and data.

[0052] The elevator door opening and closing time and speed measuring device includes a measuring terminal 100, a speed measuring module 200, and a bracket 300. Before measurement, the suction cup 210 is attached to the elevator button panel 430, and the fastening knob 312 is adjusted so that the rolling surface of the roller 230 is on the same plane as the door panel of the first elevator door 410, and the roller 230 is adjusted to be close to the side of the elevator button panel 430. The bracket 300 consists of multiple bracket arms. The first end of the bracket 300 is connected to the suction cup 210, and the second end of the bracket 300 is equipped with the roller 230 and the rotary encoder 240, which can adapt to different elevator door sizes and installation environments, ensuring that the speed measuring module 200 works normally when the elevator door opens and closes. The door opening start time or door closing start time is simultaneously acquired the instant the door opening button 431 or door closing button 432 is pressed by triggering the switch 150 via the button. The door opening end time or door closing end time is determined the instant the roller 230 stops rotating, which can improve the accuracy of elevator door opening and closing time measurement. Furthermore, by continuously recording the car door running speed during the elevator opening and closing processes through the roller 230 and rotary encoder 240, the elevator opening speed curve and closing speed curve can be quickly obtained on-site, and the opening and closing speed curves can be analyzed to improve the efficiency of elevator installation, commissioning and testing.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
