Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-climbing energy-absorbing devices, in particular to a train anti-climbing energy-absorbing device filled with foam aluminum and deformable capsules. BACKGROUND

[0002] When the head of a train collides with the tail of the front train, if the strength of the connecting point is insufficient to break or fail, the rear vehicle may be wedged under or above the front vehicle, causing the vehicle structure to be stacked and penetrated like a telescopic telescope, and the huge impact energy generated will be directly transmitted to the passengers and vehicles through the vehicle structure with almost no loss, resulting in disastrous consequences. At this time, the anti-climbing energy-absorbing device comes into being. This structure can effectively prevent the climbing between trains, and greatly reduce the impact generated by the collision to avoid direct action on the vehicle body.

[0003] Most of the existing anti-climbing energy-absorbing devices use honeycomb energy absorbers as the main buffer structure, but the traditional continuous honeycomb structure forms a wave front contact area in the collision, and the stress wave propagation reflection causes load fluctuation, and the utilization rate of the energy-absorbing element is low. Moreover, the buffering effect of the pure honeycomb energy absorber is limited and cannot bring sufficient safety. To solve these problems, the present application proposes a new type of train anti-climbing energy-absorbing device filled with foam aluminum and deformable capsules. SUMMARY

[0025] Compared with the prior art, the beneficial effects of the present application are: 1) When the anti-crawling energy-absorbing device is used, the shell of the anti-crawling mechanism is provided with a hexagonal alloy buffer group, and the hexagonal alloy buffer group is filled with porous aluminum foam. When the anti-crawling plate is impacted, the impact acts on the hexagonal alloy buffer group, so that the hexagonal alloy buffer group folds along the folds arranged in the interior, and is buffered by the porous aluminum foam in the interior, effectively offsetting the impact force and avoiding direct action on the train. The impact force can be monitored in real time by the first pressure sensor.

[0026] 2) When this anti-climb energy-absorbing device is in use, a side shell is provided inside the rear shell of the buffer mechanism, and a clamping shell is provided inside the side shell. The clamping shell and the contact plate on the push plate are fitted together. The elastic bladder squeezes out the high-friction liquid inside it from the contact plate to the end face of the clamping shell through its own squeezing force, thereby increasing the sliding friction between the contact plate and the clamping shell, making the push plate more difficult to push, and making the buffer mechanism more effective.

[0027] 3) When this anti-climb energy-absorbing device is in use, a triangular block is installed in the rear shell of the buffer mechanism. An alloy cutter head is connected to the end face of the triangular block. When the push plate drives the cutting block to move backward, the alloy cutter head will cut the end face of the cutting block, converting kinetic energy into the energy required to cut metal and the heat energy to generate metal chips. This effectively alleviates the impact brought by the push plate. Moreover, the downward pressing cutting block will squeeze the drive plate. Through the transmission of multiple structures, the moving plate drives the push plate to move outward, thereby enabling the triangular block to perform a feeding action, which facilitates timely contact with the surface of the cutting block.
