Elevator Guide System
The guide system: The elevator's anchor of stability, like a skilled helmsman, ensures smooth and safe operation. It comprises a precise system of key components, including guide pulleys, return pulleys, and guide rails, which work together to provide stable guidance for the elevator. Among the eight major systems in an elevator, it plays a crucial role, effectively ensuring safe and smooth operation.
Specific components and functions are as follows:
Core Function
★ Restricting Freedom
Constrains the range of motion of the car and counterweight, forcing them to rise and fall only along the vertical guide rails, preventing lateral deviation or swing and ensuring operational stability.
★Safety Support
When the safety clamp is activated, the guide rails act as load-bearing supports to absorb impact energy and prevent the car or counterweight from accidentally falling.
Components
★ Guide Rails
Utilizes high-strength T-shaped steel rails, fixed vertically to the shaft wall, providing a rigid running track for the car and counterweight. Guide Shoes
Installed on both sides of the car frame and counterweight frame, they contain anti-friction pads (such as nylon or composite materials) and slide tightly against the guide rails, reducing vibration and providing guidance.
★ Guide Rail Frames
A metal support structure that securely attaches the guide rails to the hoistway wall and withstands dynamic loads during operation.
System Interaction
Working in conjunction with the traction system
As the guide shoes slide along the guide rails, they ensure that the traction force of the traction wire rope is accurately converted into vertical motion, preventing deflection and wear of the wire rope.
Safety Protection Foundation
They provide rigid support for the overspeed governor-safety gear linkage and are the key physical support for emergency elevator stops.
Design Features
The guide rails must meet a straightness tolerance of ≤0.7mm/m. If the guide shoe pads exceed 40% of their original design thickness, they must be replaced to maintain system accuracy.
The following is a standardized maintenance process and key points for elevator guide systems, compiled based on current special equipment specifications:
Periodic Maintenance Requirements
★ Biweekly Inspection (every 15 days)
★ Guide Shoe Inspection: Measure the wear of the liner thickness. If it exceeds 40% of the original design, replace it immediately. Clean dust from the guide shoes and refill with special grease.
Guide Rail Frame Bolt Tightening: Retighten with a torque wrench to prevent bracket displacement and guide rail deflection.
Quarterly Inspection (every three months)
★ Guide Rail Straightness Calibration: Use a laser alignment instrument to check verticality. If the deviation exceeds 0.7mm/m, adjust the bracket position.
Guide Shoe Clearance Adjustment: Maintain a 1-2mm clearance between the sliding guide shoe and the guide rail. Perform a pressure balance test on the rolling guide shoe spring.
Annual Inspection (every 12 months)
Guide Rail Rust Treatment: Polish rusted areas and apply anti-rust grease. Severely deformed sections (>2mm) require replacement. Safety Gear Interlocking Test: Forcefully trigger the safety gear to verify that the guide rail can withstand impact loads (without plastic deformation).
Key Operating Procedures
Cleaning Management
Pooled water at the bottom of the shaft must be promptly drained to prevent rust and expansion of the guide rail base.
Wipe the guide rail working surface clean of oil stains with a non-woven cloth; corrosive solvents are prohibited.
Lubrication
Use elevator-specific lithium-based grease, applying enough to cover 60% of the guide rail working surface. Excessive lubrication can attract dust and increase wear.
Only lubricate the bearing area of the roller guide shoe; do not lubricate the rubber wheel surface (to prevent slipping).
Precision Control
Guide rail joint step difference ≤ 0.05mm, finishing length > 150mm.
Adjacent guide rail brackets maintain levelness error < 1.5mm, with spacing ≤ 2.5m.
Safety and Emergency Response Points
Pre-Maintenance Procedures
Disconnect the main power supply, lock the door, and test the emergency stop switch.
Fault Interaction
If a guide rail is found to be partially bent, stop the elevator immediately and check for counterweight misalignment.
If the guide shoe makes an unusual noise accompanied by car vibration, prioritize checking for traction rope tension deviation (must be <5%).
Technical Standard Note
Annual maintenance must include a 125% rated load brake test to verify the guide system's rigid support capacity.
