Description

Technical Field

[0001] This utility model relates to the field of elevator testing technology, and in particular to an elevator overload operation test and inspection device. Background Technology

[0002] The overload operation test is a new special inspection requirement for elevators. The requirements for the elevator overload operation test are as follows: the elevator car is loaded with a load of 110% of the rated load, and the elevator is started, operated in its entirety, stopped, and operated normally and opened and closed 60 times in a continuous cycle without interruption, to check whether the elevator has any faults.

[0003] In actual testing, elevator overload operation tests generally require a considerable amount of time. Taking a 32-story residential elevator with a rated speed of 2.5 m / s as an example, a single full run typically takes about 55 seconds. Including the brief stop time between runs, the entire test is expected to take no less than one hour. Currently, inspectors need to spend a long time on-site confirming the elevator's status during the test. The opening and closing of the elevator landing doors and car doors requires multiple people to continuously check at the upper and lower stations, and record the number of elevator runs. Inspectors also need to promptly identify abnormal situations during the test, such as elevator malfunctions leading to emergency stops or artificially extended stop times, and immediately inform the auxiliary operators of test failures. This method, relying solely on manual on-site inspection, is inefficient, time-consuming, and labor-intensive, and suffers from low digitization of the test supervision process and the inability to effectively reconstruct the inspection process.

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figures 1 to 3This embodiment discloses an elevator overload operation test device, including a test host 100 and an acceleration acquisition module 200. The test host 100 includes a housing 110, a camera 120, a sound sensor 130, and a processor 140. The camera 120 is mounted on the housing 110, and the sound sensor 130 is disposed inside the housing 110. The processor 140 is electrically connected to the camera 120 and the sound sensor 130 respectively. The camera 120 is used to acquire images of the load state of the elevator car 400 and the opening and closing state of the elevator door. The sound sensor 130 is used to acquire sound pressure data inside the elevator car 400. The acceleration acquisition module 200 is equipped with a triaxial acceleration sensor 210, which is wirelessly connected to the processor 140. The triaxial acceleration sensor 210 is used to acquire triaxial acceleration during the operation of the elevator car 400.

[0025] This elevator overload operation testing device achieves comprehensive monitoring of the elevator's operating status through a testing host 100 and an acceleration acquisition module 200. The housing 110 of the testing host 100 provides overall structural protection. A camera 120 is used to collect real-time data on the load status of the elevator car 400 and the opening and closing of the elevator doors. A sound sensor 130 can capture any abnormal sounds that may occur during elevator operation, ensuring the elevator operates safely. A processor 140 processes the data from the camera 120 and the sound sensor 130. The triaxial accelerometer 210 in the acceleration acquisition module 200 captures the vibration and acceleration changes of the elevator during operation, accurately recording the elevator's operating status and transmitting the data to the processor 140 for processing via wireless communication. The inspection host 100 first monitors the elevator load and abnormal sounds during operation through the camera 120 and the sound sensor 130. The processor 140 analyzes the collected image and sound data. Subsequently, the triaxial accelerometer 210 sends the acceleration change information of the elevator during operation to the processor 140 for comprehensive analysis via wireless communication, automatically recording the elevator's operating status and overload conditions, thereby improving inspection efficiency and accuracy.

[0026] Please see Figure 1 and Figure 3 The camera 120 is movably connected to the housing 110, and its rotation angle is adjustable. The camera 120 is used to capture the load status and door opening / closing status of the elevator car 400. It is movably connected to the housing 110, and the camera 120 can rotate. The rotation angle of the camera 120 on the housing 110 can be adjusted to set the image acquisition angle, thereby comprehensively capturing images inside the elevator car 400.

[0027] Please see Figure 3The housing 110 has a sound pickup hole 111. A sound sensor 130 is located inside the housing 110 and near the sound pickup hole 111. The sound sensor 130 reads external sound signals through the sound pickup hole 111. The sound pickup hole 111, located on the housing 110, guides external sound signals into the housing. The sound sensor 130, installed inside the housing 110 and near the sound pickup hole 111, captures the sound waves transmitted through the sound pickup hole 111 and converts them into electrical signals. External sound enters the area where the sound sensor 130 is located through the sound pickup hole 111. The sound sensor 130 converts the received sound waves into electrical signals, thereby enabling the reading of external sound signals.

[0028] Please see Figure 3 and Figure 4 The housing 110 is equipped with a display screen 150 and a rotating shaft 160. The display screen 150 is fitted onto the rotating shaft 160 and is electrically connected to the processor 140. The display screen 150 is used to display the elevator overload operation test status. The display screen 150 and the housing 110 are foldable, and the display screen 150 can be unfolded and folded through the rotating shaft 160.

[0029] Please see Figure 3 and Figure 4 The housing 110 has a rectangular parallelepiped structure, and the display screen 150 is a touchscreen. The rectangular parallelepiped design of the housing 110 provides physical protection and support for each module. For example, the camera 120 is located at the front of the housing 110, and the sound sensor 130 is located inside the housing 110. The display screen 150 uses touchscreen technology, improving the convenience and intuitiveness of human-computer interaction, allowing for interaction through simple touch operations. The stable support of the housing 110, combined with the display screen 150, enables efficient implementation of various functions through touch operations, improving user experience and operational convenience. For example, inspectors can use the touchscreen to input elevator parameters, input test parameters, start and end tests, view recorded results during the test, and export test record reports.

[0030] Please refer to Figure 1 The testing host 100 is also equipped with a power button 171 and an indicator light 172, both of which are electrically connected to the processor 140. The power button 171 controls the power supply to the host. The indicator light 172 displays the host's operating status; it illuminates when the host starts up or is running normally, providing intuitive feedback to the user. The processor 140 controls the indicator light 172 to illuminate or extinguish according to the host's operating status based on received signals, thus providing visual feedback on the operating status of the testing host 100.

[0031] Please see Figure 4The inspection host 100 also includes an audible and visual alarm module 180, which comprises a sound alarm component and a visual alarm sub-component. For example, if a door opening / closing malfunction is detected before the test completes 60 full runs, an audible and visual alarm is issued to alert the inspectors that the test has failed; if no elevator malfunction is detected during the successful completion of the 60 full runs, an audible and visual alarm is used to notify the inspectors that the test has succeeded. This allows for the immediate detection and alarm of elevator problems during the test, improving inspection efficiency.

[0032] Please see Figure 1 and Figure 2 The inspection host 100 also has a wireless communication module 190 installed inside. The wireless communication module 190 is electrically connected to the processor 140 and uses Wi-Fi or Bluetooth communication. The triaxial accelerometer 210 communicates with the inspection host 100 wirelessly to realize triaxial acceleration measurement, control, and data transmission.

[0033] Please see Figure 5 The elevator overload operation test device also includes a bracket 300, which is used to place the test host 100. For example, the bracket 300 is a tripod, which makes it more stable to place the test host 100 on the tripod.

[0034] The elevator overload operation test device includes a test host 100, an acceleration acquisition module 200, and a support 300. For example... Figure 1As shown, a load weight 500 representing 110% of the elevator's rated load is loaded onto the floor inside the elevator car 400. A bracket 300 is placed at the rear of the elevator car 400 near the car wall. The testing host 100 is fixed above the bracket 300, and the acceleration acquisition module 200 is placed on the floor of the elevator car 400. The placement of the testing host 100 allows the camera 120 to capture images of the load weight status and elevator door opening / closing status inside the elevator car 400. During the elevator overload test, the acceleration acquisition module 200 collects triaxial acceleration data from the triaxial accelerometer 210 and sends the collected triaxial acceleration data to the processor 140 for analysis of elevator motion and vibration parameters. The camera 120 continuously acquires image data inside the elevator car at a certain frame rate. The image data includes the load inside the elevator car and the elevator door status, and the image data is transmitted to the processor 140 for analysis. Sound sensor 130 collects sound pressure data within the elevator car 400 and transmits the data to processor 140 for analysis. This analysis monitors for abnormal noise during the test, such as abnormal collisions between the two doors during closing or noise caused by door jamming during opening. During the elevator overload test, display screen 150 is in the unfolded state, allowing inspectors outside the elevator to visually assess the test process via the touchscreen. For example, the touchscreen dynamically displays the number of completed elevator runs, allowing inspectors to easily track the test progress. Integrating multiple data acquisition modules (accelerometer, sound sensor, image sensor) and employing multi-sensor joint sensing of the elevator's operating status, this system enables automatic verification during elevator overload tests, achieving full recording of the test process, improving inspection efficiency and accuracy, and enhancing the digitalization of the inspection process.

[0035] 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.
