🔧 Background
Barrier gates, also known as boom barriers, are essential equipment used to manage and restrict vehicle access at entrances and exits. The gate mechanism, or barrier gate core, provides the primary driving force for the gate arm. Traditional gate mechanisms are limited in their installation flexibility—they are typically fixed in either a left-facing or right-facing configuration. This creates uncertainty and inefficiency during on-site installation.
To overcome this, Guangdong CarPass Technology Co., Ltd. has developed a reversible barrier gate mechanism that enables simple switching between left and right orientations, greatly improving on-site adaptability.
🚀 Technical Overview
The innovation lies in a simplified, modular structure that retains the proven advantages of a linkage transmission system while introducing a direction-switching capability. This design ensures the gate mechanism can be installed in both left and right orientations without altering the core structure.
▶️ Key Components:
- Reduction Motor (1): Drives the mechanism through its connection to the gearbox.
- Gearbox (2): Transmits motion to the lower part of the drive arm.
- Base Plate (4) + Bearing Seat (5): Provide mounting support for the swing shaft.
- Swing Shaft (7): Hinged to the middle of the double swing arm.
- Double Swing Arm (8): Upper end is hinged to the linkage assembly (3); the lower end connects to the connecting rod (11).
- Linkage Assembly (3): Transfers motion from the gearbox to the top of the drive arm.
- Connecting Rod (11) + Tension Spring Assembly (12): Ensure smooth, balanced motion.
- Fixed Stopper (9) + Movable Stopper (10): Provide adjustable limits for the barrier arm.
- Barrier Arm (6): Connects to the swing shaft and serves as the physical barrier.
✅ Advantages & Benefits
- Directional Flexibility: Easily switches between left-opening and right-opening configurations without needing to replace internal components.
- Simplified Structure: Retains the stability and smooth motion of traditional linkage-driven designs.
- Quick Installation: Modular design allows for efficient assembly and flexible adaptation to various on-site conditions.
- Versatile Applications: Ideal for parking lots, industrial areas, residential entrances, toll booths, and other access control systems.
