Power transmission protection mechanism for rail crane

Abstract

The invention discloses a power transmission protection mechanism for a rail crane. The power transmission protection mechanism comprises a trolley support and two reduction gearboxes, wherein the trolley support and the two reduction gearboxes are connected to the trolley, and the trolley support is located in the middle of the two reduction gearboxes; a torsion arm is connected to the reductiongearboxes, and a buffer device is connected between the torsion arm and the trolley support; the trolley support is connected with a protective baffle cover, and the protective baffle cover is buckledon the outer side of the buffer device and is clamped with the torsion arm. The power transmission protection mechanism for the rail crane is stable and reliable, and plays an effective buffering anddamping protection role on the reduction gearboxes. When the rail crane runs at a high speed, the impact force borne by the reduction gearboxes is transmitted to the buffer device through the torsionarm, the buffer device can slow down the impact force, and the buffer device plays a role in buffering and damping. If the buffer device is connected to loosen or break in the running process of therail crane, the protective baffle cover is clamped with the torsion arm, so that a stable connection between the torsion arm and the trolley support is ensured, and the turnover side of the reductiongearboxes is prevented from overturning.

Description

technical field [0001] The invention relates to the technical field of rail cranes, in particular to a power transmission protection mechanism for rail cranes. Background technique [0002] The automatic high-speed rail crane is a loading and unloading equipment applied to the vertical layout of the container automated terminal yard. It mainly interacts with the automatic navigation vehicle and the outer collection truck at both ends of the sea and land sides of the yard. The speed of the cart is as high as 270 m / min. The torque arm system is used to connect the reduction box and the car body of the high-speed rail crane to play the role of fixing, buffering and shock absorption. Compared with the traditional rail crane, the automated high-speed rail crane not only plays the role of loading and unloading, but also undertakes the function of handling. The utilization level of the automatic high-speed rail crane cart mechanism has been greatly increased from T5 to T8. It has h...
