(1) When the cage is dropped onto the receiving device at a speed of 2.96 m/s (measured voltage of 95V), it fails to pass through the receiving device's claw, and there is a noticeable cushioning effect.
(2) At a higher speed of 4.67 m/s (measured voltage of 150V), the cage successfully passes over the claws, with the bottom tray, upper tray, and can cap all clearing the receiving mechanism without obstruction.
(3) The goats remained safe during the impact test, confirming the effectiveness of the safety system.
(4) After the over-discharge test, the device can be immediately returned to its normal parking position, and the receiving device resumes full functionality without requiring any additional maintenance or adjustments.
Performance Evaluation of the Spring-Buffered Safety Receiving Device:
The spring-buffered safety receiving device primarily utilizes a compression spring to absorb the impact force during loading and unloading of mine cars. In the event of an over-discharge accident, it ensures the safe passage of the cage. Following industrial testing and on-site implementation, the device has proven to be not only simple in design and easy to install, but also accurate in positioning, user-friendly, responsive, and highly reliable. It demonstrates strong adaptability, minimal loading impact, low failure rate, and low maintenance requirements. Additionally, it does not require external power, eliminates the need for repeated tank adjustments, reduces the physical effort needed for loading and unloading, and improves overall efficiency.
Moreover, the device offers several key advantages:
(1) Due to the precise loading position, the cart remains stable relative to the receiving device, which prevents the mine car from falling off during operation. This enhances both the safety of the vehicle and extends the lifespan of the cart machine.
(2) The impact on the metal structural beam at the lower wellhead is significantly reduced, resulting in less maintenance required for the beam.
(3) The operation at the wellhead is simplified for the operator, signal worker, and driver, thereby reducing the likelihood of human error.
(4) With the removal of the lower shaft cradle and the inherent durability of the spring buffer system, the receiving device requires far less maintenance, leading to significant cost savings in both maintenance and replacement.
