Seat belt and safety net comprehensive tester

Seat belt and safety net comprehensive testermain purpose

Produced according to GB5725-2009 "Safety Nets" and GB/T6096-2020 "Performance Test Methods for Fall Protection Safety Belt Systems", it is mainly used to test the impact resistance and penetration performance of safety nets, as well as the static and dynamic performance of safety belts. It is widely used in special labor protection equipment supervision and inspection stations, building science research institutes, construction engineering quality inspection stations, and safety net production enterprises.

Seat belt and safety net comprehensive testerHost structure

1. The main frame is made of 6 galvanized square tubes of 14 # * 5, which have undergone rust prevention treatment and professional finite element analysis to ensure the safety and stability of the overall testing frame. The main frame can also provide personalized customization solutions according to specific customer needs.

2. The hanging net testing rack is scientifically and reasonably designed, directly designed as a three station size, which can directly achieve safety net testing of conventional widths such as 3 meters, 1.8 meters, and 1.5 meters.

3. Adopting an upper and lower stacked structure, it only requires a 6.5-meter * 3.5-meter testing space, which is a small footprint solution for safety nets with a testing length of 6 meters and a width of 3 meters.

4. There are two options: leveling the ground and digging pits on the foundation, which can be chosen according to the customer's needs.

5. This product is a comprehensive testing instrument developed by our company for the strength testing of seat belts based on user needs. The main structure of the instrument is welded from a steel structure, and the bottom is fixed and sturdy with bolts. The testing rack adopts a comprehensive design concept, which reduces the overall footprint of the seat belt testing rack. The test stand adopts a ground level raised structure and can be used for dynamic load testing and static load testing of fall suspension safety belts as a whole; Overall static load test of safety belts for pole work and area restricted safety belts.

Measurement and Control System

1. The overall control system adopts a PLC+touch screen control structure. The relevant operations can be completed through touch screen.

2. The touch screen adopts domestic brands and is equipped with a large capacity RAM memory; TFT LCD 4-wire precision resistance grid touch display, equipped with a 400MHz high-speed CPU, with faster response speed and stronger processing capability.

3. The steel ball and penetrating rod adopt an electric suction and release system, which is completed through a touch screen.

4. The impact height of the safety net can be set by the touch screen and displayed in real-time. Set the height to automatically stop lifting or lowering.

5. Configure an impact height ranging system, using a 6-point constant torque induction ranging structure.

6. The dedicated national standard pulley overcomes the drawbacks of other similar equipment that cannot be lowered by a separate release device and the steel wire rope rotates.

protection system

1. The test rack is equipped with a vertical protective cage ladder to ensure the safety of operators.

2. Main components such as impact hoists should have protective measures against rain to extend the service life of the equipment.

3. The hoist is equipped with a limited position function to ensure that the limit state lower limit protection stops running.

4. The impact release device adopts PUR spiral spring cable connection, which is resistant to UV aging, high and low temperature, and has good wear resistance.

Key Metrics

1. Impact height: 0-7.5m can be set by the touch screen, with standard impact heights of 7.0m, 2.0m, 1.8m, and 1.5m.

2. Penetration height: Standard 1m height.

3. Impact samples: Completed samples with standard test sizes of 3m × 6m, 1.8 m × 6m, and 1.5 m × 6m.

4. Penetrating sample: a cut sample with a standard test size of 1m x 1m.

5. Impact steel ball: Weight 100 ± 1kg, diameter 500 ± 10mm, smooth surface. If necessary, you can weight yourself.

6. Penetrating rod: Weight 5 ± 0.2kg, diameter 50mm round rod, end face with small cross-section and sharp edges, rounded corners smaller than R1.

7. Instrument power supply: AC 380V, 50Hz, four wire system.

8. Instrument size: 6.5m × 3.5m × 12m, and there should be space for crane and other activities for equipment installation.

Overall dynamic load test of seat belt

The seat belt function can be used for overall dynamic load testing of fall suspension seat belts and dynamic load testing of components; Static load testing of safety belts for pole work, static load testing of safety belts for area restrictions, static load testing of safety belts for fall suspension, etc.

The dynamic testing part of the seat belt uses high-precision dynamic force sensors to collect dynamic forces, a high-speed bandwidth data acquisition and processing system, and automatic locking of large impact force values; The static testing part of the seat belt uses high-precision static sensors to collect force values, which can be displayed in real time. Static experiments can achieve automatic loading, maintain the set force value, and achieve automatic lifting.

According to the provisions of GB/T 60962020 "Test Methods for Seat Belts" for seat belt experiments, prepare the required samples and perform sample pretreatment.

During the experiment, the test seat belt will be worn on the simulated person normally. Please refer to the relevant standards for details.
