Description

Technical Field

[0001] This utility model relates to the field of elevator testing technology, and in particular to an intelligent self-testing safety elevator. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, primarily used for the vertical transportation of people or goods in multi-story buildings. It generally consists of a car, guide rails, a traction system, a counterweight, and safety devices. The car is the space for carrying people or goods. The guide rails guide the car's up and down movement, ensuring smooth operation. The traction system provides power, moving the car along the guide rails via cables or other means. The counterweight balances the weight of the car, reducing the load on the electric motor. Safety devices are crucial, including speed governors and safety brakes. When the elevator experiences overspeeding or other abnormal situations, these safety devices activate quickly, stopping the car and ensuring the safety of passengers and goods. The advent of elevators has dramatically changed people's lives and work. Whether in residences, shopping malls, office buildings, or hospitals, they play an irreplaceable role, allowing people to quickly and conveniently reach different floors.

[0003] Elevators are frequently used electromechanical devices. During daily operation, various elevator components, such as the traction machine, guide rails, and car doors, are constantly subjected to wear and tear. For example, the repeated opening and closing of the car doors every day can easily cause components of the door operator system to become loose or deformed. Regular inspections can help detect these wear problems in a timely manner, allowing damaged parts to be replaced and preventing malfunctions caused by component failure.

[0004] When problems arise with the comfort, reliability, and safety of traditional elevators, they still rely on the mandatory 15-day on-site maintenance service mandated by national regulations. Even then, the ability to detect problems depends heavily on the maintenance personnel's work attitude and experience. More dangerously, many mechanical malfunctions, such as problems with the bearings of the deflector pulley, can lead to damage to the pulley shaft within one to two days, from the initial abnormal noise to vibration. This can cause the elevator cable to escape from the deflector pulley, resulting in a high-altitude fall of the elevator car and potentially causing a major accident with unimaginable consequences. Therefore, to address these shortcomings, a smart, self-detecting safety elevator is proposed to solve these problems. Utility Model Content

[0014] As a further description of the above technical solution:

[0015] The quick-release assembly includes two sliding rods, the outer sides of which are slidably connected to the front and rear sides of the interior of the positioning plate, respectively. A retaining plate is fixedly connected to the adjacent side of each sliding rod. A retaining ring is fixedly connected to the outer side of each sliding rod.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an intelligent self-detecting safety elevator, comprising a top plate 1, which serves as the top support structure for the entire elevator assembly. A traction assembly for providing power is mounted on the top of the top plate 1. The traction assembly includes a mounting plate 2, the bottom of which is fixedly connected to the top of the top plate 1. A traction machine 3 is mounted on the front side of the mounting plate 2, providing a stable mounting base for the traction machine 3. A rotating wheel 4 is fixedly connected to the output end of the traction machine 3. A traction rope 5 is sleeved on the outside of the rotating wheel 4. One end of the traction rope 5 is fixedly connected to the bottom left side of the top plate 1, and the other end is fixedly connected to the bottom right side of the top plate 1. A return rope pulley 12 is sleeved on the outer left side of the traction rope 5. The traction rope 5 is subjected to the gravity of the elevator car 6 and the counterweight assembly, and achieves the lifting and lowering movement of the car through cooperation with the rotating wheel 4. The external fixed connection of the return rope wheel 12 is a fixed frame 11, the top of the top plate 1 is fixedly connected to two fixed plates 13, the adjacent side of the two fixed plates 13 is fixedly connected to a guide wheel 14, the external right side of the traction rope 5 is slidably connected to an installation frame 15, and the internal fixed connection of the return rope wheel 16 is fixedly connected to the installation frame 15.

[0034] Reference Figures 1 to 3The bottom of the traction assembly is equipped with a support assembly for supporting the elevator. The support assembly includes a base plate 7, the top of which is fixedly connected to the bottom of the elevator car 6. The base plate 7 serves to support and bear the weight of passengers and goods inside the car, as well as various impacts and vibrations generated during elevator operation. A support frame 8 is fixedly connected to the bottom of the base plate 7. Two connecting plates 9 are fixedly connected to the top of the support frame 8. The connecting plates 9 enhance the integrity and stability of the support assembly. A support plate 10 is fixedly connected to the top of the two connecting plates 9. The bottom of a fixed frame 11 is fixedly connected to the top of the support plate 10, and the support plate 10 provides support for the fixed frame 11. An elevator car 6 is fixedly connected to the top of the support assembly. A positioning plate 23 is fixedly connected to the top right side of the elevator car 6. A quick-release assembly for quick release is provided inside the positioning plate 23. A second mounting plate 33 is fixedly connected to the top of the quick-release assembly. A self-detection device 34 is fixedly connected to the top of the second mounting plate 33. A sound collector 35 is installed on the top of the self-detection device 34. A vertical vibration collector 36 is installed on the top of the self-detection device 34. A horizontal vibration collector 37 is installed on the top of the sound collector 35. A control module 38 is fixedly connected to the rear top of the second mounting plate 33.

[0035] Reference Figures 1 to 3 A counterweight assembly is installed on the bottom right side of the top plate 1. The counterweight assembly includes a counterweight block 17, the top of which is fixedly connected to the bottom of the mounting frame 15. The function of the counterweight block 17 is to balance the weight of the elevator car 6, reduce the load on the traction machine 3, and improve the elevator's operating efficiency and safety. A sliding frame 18 is slidably connected to the outside of the counterweight block 17. The sliding frame 18 cooperates with the guide frames 20 on the front and rear sides of the counterweight block 17 to ensure that the counterweight block 17 can move smoothly up and down in the vertical direction during elevator operation without deviation or shaking. Two guide grooves 19 are opened inside the sliding frame 18. Guide frames 20 are fixedly connected to the front and rear sides of the counterweight block 17. The outside of the guide frames 20 is slidably connected to the inside of the guide grooves 19, which provide sliding tracks for the guide frames 20 of the counterweight block 17. A base 21 is fixedly connected to the bottom of the guide frame 20, which supports and fixes the guide frame 20. The bottom of the base 21 is fixedly connected to a support 22. The support 22 is usually connected to the bottom of the elevator shaft by bolts or welding to ensure that the heavy components will not shift or sink during the operation of the elevator, thus ensuring the normal operation of the elevator.

[0036] Reference Figure 2 , Figure 4 and Figure 5The quick-release assembly includes two sliding rods 24, which are slidably connected to the front and rear sides of the interior of the positioning plate 23, respectively. A retaining plate 25 is fixedly connected to the adjacent side of each sliding rod 24. The sliding rods 24 serve to connect and fix the retaining plates 25. A retaining ring 26 is fixedly connected to the exterior of each sliding rod 24, limiting the sliding range of the sliding rod 24 within the positioning plate 23. A sliding ring 27 is slidably connected to the exterior of each sliding rod 24, slidably connected to the interior of the positioning plate 23, ensuring the sliding rod 24 can rotate freely. A spring 28 is fitted onto the exterior of each sliding rod 24, providing elasticity so that the retaining plate 25 can be tightly engaged in the retaining groove 32 under normal conditions, thus securing the self-detection device 34 and the control module 38. Pull plates 29 are fixedly connected to the opposite sides of the two sliding rods 24. Pull plates 29 allow operators to easily rotate the sliding rods 24 and the locking plate 25 by pulling them. A locking block 30 is slidably connected inside the positioning plate 23. The locking block 30 works in conjunction with the locking plate 25 to position the self-detection device 34 and the control module 38. Two sliding grooves 31 are formed inside the locking block 30, serving as sliding tracks for the locking plate 25. The locking plate 25 is slidably connected to the inside of the sliding grooves 31. Two locking slots 32 are formed inside the locking block 30, serving as rotation and engagement spaces for the locking plate 25. The external rotatable connection of the card plate 25 is inside the card slot 32. When it is necessary to disassemble the self-detection device 34 and the control module 38, the pull plate 29 is rotated to drive the sliding rod 24 and the card plate 25 to rotate, so that the card plate 25 is disengaged from the card slot 32 and aligned with the sliding groove 31. Then, with the help of the elastic force of the spring 28, the card plate 25 is slid out from the inside of the card block 30, thereby realizing disassembly.

[0037] Working principle: When it is necessary to perform a full inspection of the elevator car 6, the traction machine 3 is started to drive the rotating wheel 4 and the traction rope 5 to rotate. Then, the elevator car 6 and the counterweight assembly can be raised and lowered with the help of the return rope wheel 12 and the return rope wheel 2 16. When the elevator car 6 and the counterweight assembly meet, the self-detection device 34 installed on the top of the elevator car 6 will automatically detect the counterweight assembly. When the elevator car 6 runs to the top floor, the self-detection device 34 detects the traction machine 3 and the speed governor in the machine room. When the elevator car 6 runs to the bottom floor, the self-detection device 34 self-detects the speed governor tension wheel and the compensation chain in the pit. The system achieves full-process, all-round detection without leaving any blind spots. At the same time, the self-detection device 34 feeds back the sound data, vertical vibration data, and horizontal vibration data detected by the sound collector 35, vertical vibration collector 36, and horizontal vibration collector 37 to the control module 38. If any set of data exceeds the normal operating data, the control module 38 first activates the elevator safety circuit to stop the elevator after transporting the passengers to the nearest floor, ensuring the safety of the elevator and avoiding major accidents. Subsequently, the control module 38 notifies the service provider via the Internet to conduct inspection and repair.

[0038] When the self-testing device 34 and control module 38 need to be disassembled and repaired, simply rotate the pull plate 29 to rotate the sliding rod 24 and the clamping plate 25. This will cause the sliding rod 24 to rotate inside the sliding ring 27, thereby aligning the clamping plate 25 with the slide groove 31. Then, with the help of the spring force of the spring 28, the clamping plate 25 can be disengaged from the slide groove 31, allowing it to slide out from the inside of the clamping block 30. This enables the disassembly of the clamping block 30 and the mounting plate 33, and thus the disassembly and repair of the self-testing device 34 and control module 38. When installation is required, simply reverse the above steps to install and position the clamping block 30, thereby enabling the rapid installation of the self-testing device 34 and control module 38.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
