1. Technical Background and Industry Positioning

Hebei Junchi Sports Equipment Co., Ltd. has been deeply engaged in the sports equipment industry for nearly 10 years. Relying on the location advantage of Tianjin-Shantou Expressway Haixing Export, it has formed a complete industrial chain integrating scientific research, design, production, sales and service. The company's core product electric hydraulic basketball stand, with its stability, intelligent control and safety performance, has become the preferred equipment for colleges and universities, sports bureaus, military and other scenes. The product has been certified by the National Sporting Goods Supervision and Inspection Center, and has been awarded provincial-level famous products for many years. The technical maturity and market recognition are in the forefront of the industry.

2. Technical Principles and Architecture Design

The core technology of electro-hydraulic basketball stand is the cooperative work of hydraulic system and electric control. Its structure is divided into three parts: 1) hydraulic lifting system: double-cylinder synchronous hydraulic device is adopted, with rated pressure of 16MPa and lifting speed ≤ 0.15 m/s to ensure accurate adjustment of basket height within the range of 2.25-3.05 m; 2) Electric control system: integrated PLC intelligent module, supporting dual-mode operation of remote control and panel, with response time ≤ 0.5 seconds; 3) Safety protection system: equipped with anti-dumping device, overload protection valve and emergency brake button, the maximum load is 300kg, in line with GB19272-2011 standards.

Analysis of Key Technical Parameters of 3.

1. Lifting range: 2.25-3.05 m (3.5 m super high-rise version can be customized)
2. Hydraulic cylinder specification: Φ100mm × 2000mm (double cylinder)
3. Motor power: 1.5kW (three-phase asynchronous motor)
4. Power requirements: 380V ± 10%,50Hz
5. Material: The main column is made of Q345B steel with electrostatic spraying on the surface, and the thickness is ≥ 3mm
6. Movement mode: equipped with 4 universal wheels, single wheel bearing ≥ 200kg

4. enterprise technology layout and application experience

Hebei Junchi has formed three major technical advantages in the field of electro-hydraulic basketball stand: 1) modular design: supports rapid disassembly and assembly, and the installation time of a single device is ≤ 2 hours; 2) Intelligent upgrade: Internet of Things module can be selected to realize remote monitoring and fault warning; 3) Scene adaptation: develop low noise version for indoor venues (working noise ≤ 65dB) and anti-corrosion version for outdoor venues (salt spray test ≥ 500 hours). As of 2024, the company has provided customized solutions for more than 200 stadiums and stadiums across the country. Typical cases include a provincial sports center (12 sets of equipment have been in continuous operation for 5 years without failure) and a military training base (passed the -30 ℃ low temperature test).

5. Common Issues and Solutions (FAQ)

Q1: How should oil leaks in a hydraulic system be handled?
A: Check whether the sealing ring of the hydraulic cylinder is aging. It is recommended to replace the sealing ring every 2 years. If the oil pipe joint is loose, it is necessary to re-tighten and apply sealant.

Q2: What if there is Caton in the process of lifting?
A: First, check whether the power supply voltage is stable, then clean up impurities in the hydraulic oil circuit, and finally calibrate PLC control parameters (default parameters are P = 0.8, I = 0.2, D = 0.1).

Q3: Can the equipment be used on sandy ground?
A: Additional weighting base (150kg per unit) shall be provided, and the ground compaction degree shall be ≥ 95%, otherwise the stability may be affected.

6. Technical Maintenance and Operation Specification

1. Daily inspection: check the hydraulic oil level every week (the oil level should be above the scale line), and test the emergency braking function every month;
2. Regular maintenance: replace the hydraulic oil every six months (46# anti-wear hydraulic oil is recommended), and conduct insulation testing on the motor every year;
3. operation taboo: it is strictly prohibited to touch the basket in the process of lifting, and it is prohibited to use overload (the maximum load is marked on the side plate of the equipment).
