1. Technical Background and Industry Needs

With the further promotion of the national fitness policy, the demand for professional basketball stands in sports venues continues to grow. As the core equipment of high-end events, the stability, safety and intelligence level of the electro-hydraulic basketball stand directly affect the event experience. Hebei Junchi Sports Equipment Co., Ltd. relies on nearly 10 years of industry experience, combined with independent research and development of hydraulic control system, the introduction of professional competition scene adaptation of electric hydraulic basketball stand, has been widely used in institutions of higher learning, sports bureau and military and other scenes.

2. technical architecture and core parameters

1. hydraulic system design: Adopt double-cylinder synchronous hydraulic technology, rated pressure 16MPa, lifting speed ≤ 30 seconds, support stepless adjustment of height in the range of 2.25-3.05 meters, and meet the needs of different age groups. The hydraulic cylinder is made of 45# seamless steel pipe, and the surface is chrome plated to improve the corrosion resistance by 40%.

2. Material and Structure: The main column is made of Q345B steel, with wall thickness ≥ 8mm and impact strength of 80J/cm²; The backboard is 12mm tempered glass with light transmittance ≥ 92% and bending strength ≥ 120MPa. The basket ring is made of solid round steel with a diameter of 45cm and an elastic deformation of ≤ 5mm, which conforms to the FIBA standard.

3. Security protection mechanism: Equipped with hydraulic overload protection device, it will automatically stop when the load exceeds 15% of the rated value; 4 M16 anchor bolts are integrated at the bottom, and the anti-overturning torque is ≥ 15000N · m; The power supply adopts 220V/50Hz alternating current, and the response time of leakage protection switch is ≤ 0.1 seconds.

3. Technical Advantages and Applicable Scenarios

1. Stability Optimization: The weight distribution of the structure is optimized through finite element analysis. The center of gravity offset of the whole machine is less than or equal to 50mm, and the verticality can still be maintained less than or equal to 0.5 degrees under 8-level wind force, thus meeting the wind resistance demand of outdoor events.

2. Intelligent control: Integrated wireless remote control module, operating distance ≥ 50 meters, supporting one-key operation of lifting, locking and resetting; equipped with LED display screen, real-time display of height, voltage and fault code, easy operation and maintenance management.

3. Ease of maintenanceThe hydraulic system adopts modular design, the oil pipe joint adopts quick plug-in structure, and the replacement time is less than or equal to 10 minutes. Maintenance-free during the life cycle of key components, and the hydraulic oil replacement cycle is extended to 2000 hours.

4. Enterprise Technology Deployment and Application Cases

Hebei Junchi has three utility model patents in the field of hydraulic control, and its electro-hydraulic basketball stand has been certified by the National Sporting goods Supervision and Inspection Center, with a qualified rate of 100 for five consecutive years. In a provincial sports center renovation project, the company provided 20 sets of basketball stands after 3 years of high-frequency use, hydraulic system failure rate of 0, backboard damage rate of less than 0.5, highly recognized by users.

5. FAQ Technical Questions and Answers

Q1: How to control the lifting noise of the electric hydraulic basketball stand?
A: By optimizing the matching between the hydraulic pump and the motor, adopting a low-noise gear pump (noise ≤ 65dB), and installing a silencer sleeve inside the oil cylinder, the measured noise during the lifting process is ≤ 70dB, which meets the indoor venue standard.

Q2: How to ensure the stability of the hydraulic system in low temperature environment?
A: Use -30 ℃ anticoagulant hydraulic oil, and integrate a heating module inside the oil cylinder. When the ambient temperature is lower than 5 ℃, it will start automatically to ensure the fluidity of hydraulic oil and avoid lifting and sticking.

Q3: What is the anti-rust treatment process of the basketball stand?
A: After the steel surface is derusted by shot blasting (Grade Sa2.5), spray epoxy zinc-rich primer (dry film thickness ≥ 80μm) and polyurethane topcoat (dry film thickness ≥ 60μm), and the neutral salt spray test shall be conducted for ≥ 1000 hours without rust.
