Detailed Implementation

[0020] The embodiments of the present invention are described below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention. However, the listed embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments can be combined with each other, wherein the same components are indicated by the same reference numerals.

[0021] like Figure 1-3 As shown. The barrier-free elevator of this utility model includes a drive and control module, a car structure module, a safety and rescue module, and an environmental adaptability module.

[0022] The drive and control module includes: guide rails 11, which are symmetrically arranged on both sides of the shaft, and the car slides up and down along the guide rails 11. A counterweight 12, a counterweight guard plate 13, and a counterweight guide rail 17 are provided on the inner side of the guide rails. A buffer 14 is provided at the pit 15 at the bottom of the shaft.

[0023] The drive and control module also includes a permanent magnet synchronous gearless traction machine 16 (rated power 15kW) and a fully digital microcomputer control system, supporting frequency conversion, voltage regulation, and speed regulation (speed 1.6m / s), reducing energy consumption by 30%. The permanent magnet synchronous traction machine is fixed to the top of the shaft, with a wire rope diameter of 10mm and a breaking tensile strength ≥35kN. The permanent magnet synchronous gearless traction machine is positioned on both sides of the car and counterweight using a 2:1 suspension system, reducing vibration and improving operational stability. The fully digital microcomputer-controlled frequency converter adjusts the motor speed in real time to match load changes, achieving an energy efficiency of 20%. Frequency converter parameter settings: base frequency 50Hz, maximum output current 32A. The microcomputer control system integrates fault code storage, remote software upgrades, and real-time monitoring functions, supporting interconnection with smartphones (pushing operating status and estimated arrival time). The drive and control module also includes an external call panel 18, landing doors 19, and a control cabinet 10 located on the top floor. The drive and control module also includes a light curtain sensor; when a passenger is detected, the car door opens.

[0024] like Figures 3-5 As shown, the car structure module includes a fully transparent glass car 21 (dimensions 1400×2500×2800mm), with a clear doorway width of 1.2m, capable of accommodating wheelchairs and stretchers, a rated load capacity of 1600kg, and a speed of 1.6m / s. It features a built-in low-position control panel (height 0.9-1.1m) and flexible handrails 22. A wheelchair securing device 24 is installed inside the car, comprising a securing ring (set on the floor) and a safety belt. The safety belt connects to the securing ring, and the other end of the safety belt connects to a securing wheelchair. An control panel 22 is installed on the inner wall of the car 21, featuring an emergency call button (response time ≤2 seconds). An air purification system (PM2.5 ≤ 28μg / m³) is installed inside the car 21. 3The lower part of the inner wall of the car 21 is equipped with a crash barrier 25. The fully transparent observation car uses high-strength laminated glass, balancing safety and visibility, with unobstructed equipment on the top floor shaft. The glass car is fixed by a hot-dip galvanized frame, and the decorative panels are made of 304 stainless steel.

[0025] The safety and rescue module includes: a closed safety detour rescue passage (shaft), a light curtain anti-pinch device, a door lock protection system (preventing the elevator from operating when the elevator door is open), a voice broadcast system, and an emergency call intercom. The voice broadcast system automatically provides floor information, and the light curtain sensor prevents pinching injuries. The sensitivity calibration of the light curtain anti-pinch device is: detection distance 0-100mm, response time ≤0.1 seconds.

[0026] The environmental adaptability module includes: dehumidification equipment (humidity ≤55%) inside the shaft, a water-retaining slope (to prevent backflow), and a glass rain shelter. The shaft top features a fully transparent design, eliminating obstructions to the view and enhancing the sightseeing experience. Shaft construction specifications: concrete shaft net dimensions 1500×3000mm, pit depth 1700mm, top height 4900mm. A water-retaining slope (5% gradient, height ≥200mm) prevents backflow of rainwater during heavy rains, and a glass rain shelter covers the waiting area. The shaft's inner walls are coated with a moisture-proof layer, and the dehumidification equipment keeps humidity below 55%, extending component lifespan.

[0027] The elevator of this invention includes an intelligent module, which collects elevator operation data (such as wire rope slack and motor temperature). The intelligent module provides a remote monitoring platform with real-time collection of elevator operation data for predictive maintenance, reducing the failure rate by 40%.

[0028] The elevator of this invention underwent operational testing. Load test: 100 runs each under no-load, half-load (800kg), and full-load (1600kg) conditions, with vertical vibration amplitude ≤ ±0.02m and noise ≤ 42dB. Emergency braking test: The safety brake was triggered at 15% overspeed, with a braking distance ≤ 0.5m.

[0029] The elevator of this invention underwent environmental adaptability testing: Simulated heavy rain (50mm / h): The water-retaining slope effectively prevented water accumulation, and there was no leakage in the shaft. High humidity environment (90%): After the dehumidification equipment operated for 2 hours, the humidity in the shaft dropped to 55%.

[0030] The elevator of this utility model is used as follows: 1. User calls the elevator: Wheelchair users call the elevator through the low-position call button (0.9m high), and the arrival time is announced via voice. 2. Entering the car: The light curtain sensor automatically opens the door, and the wheelchair fixing device inside the car secures the wheelchair. 3. Selecting a floor: The low-position control panel supports touch control and voice commands, and the air purification system is activated simultaneously. 4. Emergency: Pressing the emergency call button will trigger a real-time response from the monitoring center and activate the detour rescue channel.

[0031] The embodiments described above are merely preferred embodiments of this utility model. The terms "in one embodiment," "in another embodiment," "in yet another embodiment," or "in still another embodiment" used in this specification all refer to one or more of the same or different embodiments according to this disclosure.
