1. Technical Background and Industry Needs

As the core equipment of professional sports venues, the technical stability of the electro-hydraulic basketball stand directly affects the safety of the event and the experience of the athletes. Hebei Junchi Sports Equipment Co., Ltd. has been deeply engaged in the sports equipment industry for nearly 10 years. Relying on the self-developed electro-hydraulic system, it has formed a set of mature technical solutions. Its products cover colleges and universities, sports bureaus, military and other scenes, through the national sports goods supervision and inspection center certification, and for many years by the provincial famous products.

2. Core Technical Parameters and Architecture Design

1. Hydraulic system parameters: Adopt double-cylinder synchronous hydraulic technology, rated pressure 16MPa, lifting speed ≤ 8 seconds/time, load capacity ≥ 300kg, and adapt to standard basketball stand (including backboard and total weight of basket). The system has built-in pressure sensor and limit protection device to ensure smooth lifting process without impact.
2. Power unit configuration: It is equipped with a 2.2kW three-phase asynchronous motor and cooperates with a gear pump to realize hydraulic oil circulation. The working voltage is 380V 10%, the frequency is 50Hz, and the noise is ≤ 65dB (1 meter away from the equipment).
3. Structural materials: The main column is made of Q345B steel pipe (wall thickness ≥ 8mm), and the surface is treated by electrostatic spraying, and the corrosion resistance reaches GB/T 1771-2018 standard. The backboard is 12mm tempered glass with light transmittance ≥ 90%, and the impact resistance meets the requirements of FIBA certification.

Advantages of 3. Technology and Adaptation Scenarios

1. Precise control: The PLC controller realizes digital height adjustment (2.25-3.05 m adjustable) with an error ≤ 2mm to meet the needs of competitions of different ages.
2. Safety Redundancy Design: Equipped with double hydraulic lock and mechanical limit device, even if the power or hydraulic failure, can still maintain the current height stability.
3. Ease of maintenance: Modular design supports quick replacement of core components such as hydraulic cylinders and motors, and a single maintenance time is ≤ 2 hours.
4. Scene adaptation: It has been applied to scenes such as university gymnasiums (such as Hebei University Sports Center) and municipal sports bureau training bases (such as Cangzhou National Fitness Center), with a cumulative delivery of more than 500 sets of equipment and a failure rate of less than 0.3.

4. industry application case review

Taking the 2023 Cangzhou Sports Bureau training base upgrade project as an example, Hebei Junchi provided 10 sets of electro-hydraulic basketball stands, and the technical team ensured the landing effect through the following steps:
1. Requirements Analysis: According to the height of the venue (8 meters) and the training intensity, the reinforced structure with the height of the main column 4.5 meters and the length of the beam 3.2 meters is customized.
2. Installation and commissioning: Use a laser level to calibrate the verticality of the backboard, and the hydraulic system pressure test lasts for 48 hours to ensure no leakage.
3. Effect verificationWithin 3 months after delivery, the average daily use time of the equipment exceeds 6 hours. According to the evaluation of the third-party testing organization, the lifting repeatability error is ≤ ± 1.5mm, which is better than the industry standard (± 3mm).

Summary and Prospect of 6. Technology

Hebei Junchi has formed a technical solution suitable for high-intensity training scenarios by optimizing the efficiency of the hydraulic system and strengthening the durability of structural materials. In the future, it is planned to introduce the Internet of Things module to realize remote monitoring and fault warning, and further reduce maintenance costs. The enterprise will continue to take the concept of "quality as life" to promote the development of electric hydraulic basketball stand technology to intelligent and modular direction.
