[0002] Overhead cranes are a type of lifting equipment used in large quantities in various industrial and mining enterprises. Often, due to production needs, a high-span overhead crane and a low-span overhead crane are installed in the same span.

One end of the control rod 39 is rotatably connected to the protective cover 31, and the other end is rotatably connected to the buffer column 38, so as to cooperate with the movement of the protective cover 31 to realize the movement of the buffer slide 37 inside the buffer groove 36.

[0039] In this embodiment, a plurality of buffer grooves 36 are provided on the inner side of the support seat 29. When the protective cover 31 moves toward the side close to the support seat 29, the protective cover 31 cooperates with the control rod 39 to drive the buffer column 38 to move, and the buffer column 38 drives the buffer slide plate 37 to move inside the buffer groove 36, and cooperates with the damping fluid and the spring to absorb the impact force, thereby completing shock absorption and buffering.

By providing an automatic control component 6, not only can the automatic disassembly and assembly of the buffer energy-absorbing component 8 be completed in cooperation with the installation plug-in component 7, thereby improving the convenience of the equipment during maintenance, but also the braking unit 4 can be driven when a collision is about to occur, so as to brake the overhead crane body 2, effectively reduce the impact force, and thus improve the anti-collision buffering effect of the device. By providing an installation plug-in component 7, it can Cooperating with the automatic control component 6, the buffer energy-absorbing component 8 can be automatically disassembled and assembled, which is convenient for the repair and maintenance of the equipment. It can also cooperate with the buffer energy-absorbing component 8 to achieve multiple shock absorption, which greatly improves the anti-collision ability of the equipment and effectively avoids the situation where two vehicles collide and damage the equipment. By setting the auxiliary shock-absorbing component 22, secondary shock absorption can be achieved, and the strength of the equipment after installation can be improved, thereby improving the anti-collision buffering effect of the device. By setting the buffer energy-absorbing component 8, multiple shock absorption can be achieved after the collision, which greatly improves the anti-collision ability of the equipment and is beneficial to improving the service life of the equipment. By setting the brake unit 4, the automatic control component 6 can be cooperated before the collision to realize the automatic braking of the overhead crane body 2, thereby shortening the distance that the overhead crane moves due to inertia, thereby greatly reducing the impact intensity and ensuring the effectiveness of the buffering.
