(1) When the cage is dropped on the receiving device at 2.96m/s (measuring speed voltage 95V), the cage does not pass the receiving device claw and the buffer is obviously buffered. (2) When the cage falls on the claw at a speed of 4.67 m/s (speed measuring voltage 150 V), the bottom tray of the cage, the upper tray and the can cap all pass over the claws. (3) The goats were safe in the impact test. (4) After the over-discharge test, it can be immediately lifted to the normal parking position, and the receiving device can be restored to normal use without any treatment of the device. Performance evaluation of spring-buffered safety receiving device The spring-buffered safety receiving device mainly uses the pressure spring to buffer the impact force when loading and unloading the mine car, and can safely pass the cage in the event of an over-discharge accident. After industrial test and on-site use, the device not only has simple design, convenient installation, accurate positioning, simple operation, sensitive action, safety and reliability, strong applicability, small loading impact, low failure rate, low maintenance, no need for external maintenance. Power, no need to adjust the tank twice, reduce the loading and unloading strength, improve the loading and unloading efficiency. Moreover, it has the following advantages. (1) Because the loading position is accurate, the cart and the cart are relatively stable, which avoids the mine car falling off when the car is being operated, which not only ensures the safety of the car, but also prolongs the service life of the cart machine. (2) The impact force on the metal structural beam of the lower wellhead is small when loading, and the maintenance amount of the metal structural beam is reduced. (3) Simplified the operation of the wellhead operator, signal worker, and driver, reducing the chance of misoperation. (4) Since the lower shaft cradle is removed, and the spring buffer type safety receiving device is not easily damaged during use, the maintenance amount of the receiving device is greatly reduced, and the maintenance cost and replacement cost of the receiving device are saved.
