Safety Belt Inspection Equipment Usage Precautions
Article from the Technical Department of Qingdao Zhongbang Instrument Co., Ltd.
Seat belt testing equipment is an important testing equipment for seat belt manufacturer quality control, LA safety mark certification, and industrial production license review, as well as construction engineering inspection units and labor insurance station inspection qualification evaluation. The most important equipment is ZD-715 seat belts. The overall dynamic load static load tester, ZD-717 belt slide tester, ZW-737 salt spray test box and ZD-718 belt tension tester. Seat belt testing equipment is different from general testing equipment. Because seat belt testing equipment mostly simulates the actual use of the environment and state tests, the required test site is relatively large, and the professional degree of the laboratory personnel is required to be relatively high, and the safety awareness is relatively strong. The use of the project must strictly abide by the safety practices. The following are the precautions for the use of these devices:
First, ZD-715 seat belt overall dynamic load, static load testing machine
1. Non-professional maintenance personnel are not allowed to open the cover and disassemble and modify the internal electrical components of the instrument.
2. In case of emergency, please press the emergency stop button quickly and cut off the total power. Remove the fault and turn it on again.
3. The instrument power supply is a single-phase AC power supply and must have a reliable grounding wire.
4. When the instrument is not used for a long time or when it encounters rain or snow, the dynamic sensor needs to be removed. The following steps are taken: the person must climb to the appropriate height with the seat belt attached, remove the plastic part, remove the sensor with a wrench, and remove the corresponding connecting wire.
5. When the instrument is not used for a long time or when it encounters rain or snow, it is necessary to properly protect the device. For example, the box with the motor is covered with a rainproof cloth to prevent rain, etc. from entering the inside of the box along the hole at the top, causing damage to the motor. The controller of the electric lifting device needs to be wrapped with a rainproof cloth to prevent rainwater from entering.
6. The role of the flat lifting belt in the accessories is the secondary protection of the seat belt. When the test belt is not qualified, the flat lifting belt can only be subjected to three impacts. When testing again, the flat lifting belt must be replaced.
7. In the course of all tests, as long as the simulated person leaves the bottom surface, the tester must be 3m or more away from the rack during the process of lifting or releasing. Prevent falling accidental injuries caused by falling objects. One minute after the test is completed, the person can enter the interior of the frame to handle follow-up matters.
9, static load test, due to the test value is relatively large, in order to prevent the test specimens from breaking when the pop-up damage caused by the test personnel, on the shelf side of the test personnel to operate the safety net.
10. Be sure to equip the UPS uninterruptible power supply that matches the instrument (otherwise, under unstable power supply conditions, the simulating person has a danger of falling!). In the event of an emergency power outage, quickly turn the selector switch to “keep the pull-inâ€. Status, then turn off the power of the instrument. When the power supply is normal, the simulated person is lowered, and the selector switch is turned to the "test state" and the test is resumed.
Second, ZD-717 seat belt overall slide tester
1, the instrument must be fixed with anchor bolts.
2. The column must be fixed during the test.
3. Adjust the flap during the test so that the column is located in the slot of the flap.
Third, the belt tension machine
1. The meter on the instrument has two display windows. The first window displays the sensor force value in units of N; the second window displays the countdown time and the unit is seconds.
2. Before the test, please warm up for 15 minutes.
3, when the instrument is running, please do not put the head, hands, etc. close to the chuck and moving parts to avoid injury.
4, non-professional maintenance personnel shall not open the cover to disassemble, change the internal electrical devices.
5. In case of emergency, please quickly press the emergency stop button and cut off the total power. Remove the fault and turn it on again.
6, the instrument power supply for single-phase AC power, must have a reliable grounding line.
7. The dynamic test part of the instrument is provided with upper (lower) limit stroke protection. When the loading device is operated to the upper (lower) limit position, it will be protected. At this time, it is necessary to press “Reset†(“Startâ€) or "Drop In" ("Drop In") lowers (raises) the loading device for a distance.
8. The “reset†button on the operation panel can only be used after the end of a test, ie, the indicator light flashes and the beep 10 seconds. To stop the test midway, use the “Clear†key.
