Description

CDQ Traction Traction System and Method

technical field

The invention relates to the technical field of coke CDQ, in particular to a coke CDQ lateral movement traction system and method.

Background technique

Coke CDQ is generally arranged at the end or middle of the coke oven battery. When the CDQ is arranged at the end of the coke oven group, the center line of the hoist and the CDQ furnace is perpendicular to the center line of the quenching car track, the hoist spans above the track of the coke quenching car, and the coke tank carrier can drive Enter the bottom of the CDQ lifting derrick, and the hoist directly lifts the coke tank, walks to the top of the CDQ furnace, and loads the red coke into the CDQ furnace. When the CDQ is arranged in the middle of the coke oven group, the centerline of the hoist and the CDQ furnace is parallel to the centerline of the coke quenching car track, and the coke tank carrier cannot directly drive into the bottom of the CDQ lifting derrick, and must pass through the horizontal The moving traction device pulls the traversing trolley carrying the coke tank horizontally from the carrier vehicle, pulls it to the bottom of the CDQ lifting derrick, and then lifts the coke tank by the elevator, walks to the top of the CDQ furnace, and loads the red coke into the CDQ. Turn off the furnace.

Traversing traction device is an important equipment in CDQ red coke transportation system, which is responsible for laterally pulling the traversing trolley carrying the coke tank from the carrier vehicle to the bottom of the CDQ lifting derrick. There are two main forms of lateral traction devices currently in use:

One is the rack-and-drawn traction device; the device drives the gear to rotate through a fixed drive device, and then the rotating gear drives the rack and drawbar to complete the action of lateral traction. Due to the gear transmission, this type of traversing traction device runs smoothly, has accurate positioning, low failure rate, and can realize continuous and stable automatic operation. However, due to the long length of the rack drawbar, when the traversing trolley carrying the coke tank is drawn to the bottom of the hoisting derrick, the tail of the rack drawbar exceeds the boundary area of CDQ, which affects the process layout of CDQ , this form of traversing traction device cannot be used when the land for CDQ is tight.

The second is the wire rope winch-type traversing traction device; this device drives the wire rope through a fixed hoist arranged outside the end of the traversing stroke to pull the traction trolley to complete the traversing traction action. Due to the use of wire rope winches, the structure of the traversing traction device is compact and occupies less space. This form of traversing traction device should be used when the land for CDQ is tight. However, due to the elastic deformation and cushioning effect of the steel wire rope, this type of traversing traction device has poor motion stability and low positioning accuracy. Stable production requirements.
