Description
Technical Field
The invention relates to the technical field of dry quenching, in particular to a system and a method for transversely moving and pulling dry quenching.
Background
The dry quenching is typically arranged at the end or middle of the coke oven battery. When the coke dry quenching is arranged at the end part of the coke oven group, the center line of the lifting machine and the coke dry quenching furnace is perpendicular to the center line of the track of the coke quenching car, the lifting machine spans over the track of the coke quenching car, the coke tank carrier car can drive into the bottom of the coke dry quenching lifting derrick, the lifting machine directly lifts the coke tank, and the lifting machine moves to the top part of the coke dry quenching furnace to load red coke into the coke dry quenching furnace. When the coke dry quenching is arranged in the middle of the coke oven set, the central lines of the lifting machine and the coke dry quenching furnace are parallel to the central line of the track of the coke quenching car, the coke tank carrier car cannot directly drive into the bottom of the coke dry quenching lifting derrick, the transverse trolley carrying the coke tank is transversely pulled out from the carrier car through the transverse pulling device and pulled to the bottom of the coke dry quenching lifting derrick, and then the coke tank is lifted by the lifting machine and moves to the top of the coke dry quenching furnace to load the red coke into the coke dry quenching furnace.
The transverse moving traction device is an important device in a dry quenching Jiao Gongjiao conveying system and is responsible for transversely pulling out a transverse moving trolley carrying the coke tank from a carrier vehicle and pulling the transverse moving trolley to the bottom of a dry quenching lifting derrick. The currently used traversing traction device mainly comprises the following two forms:
firstly, a rack traction rod type transverse traction device; the device drives the gear to rotate through the fixed driving device, and then the rotating gear drives the rack traction rod to finish the action of transverse movement traction. Due to the adoption of gear transmission, the transverse moving traction device in the form is stable in operation, accurate in positioning and low in failure rate, and continuous and stable automatic operation can be realized. However, because the length of the rack traction rod is longer, when the transverse trolley carrying the coke tank is pulled to the bottom of the lifting derrick, the tail part of the rack traction rod exceeds the boundary area of the dry quenching, the process arrangement of the dry quenching is affected, and the transverse traction device cannot be adopted when the land for the dry quenching is tense.
Secondly, a steel wire rope winch type traversing traction device; the device drives the steel wire rope to pull the traction trolley to finish the action of transverse movement traction through the fixed winch arranged at the outer side of the end point of the transverse movement stroke. Because of adopting the wire rope hoist, the traversing traction device has compact structure, less occupied space and is suitable for being adopted when the dry quenching land is tension. However, due to the elastic deformation and buffering effects of the steel wire rope, the transverse moving traction device in the form is poor in motion stability and low in positioning accuracy, the traction trolley is easy to tip over and fall off, automatic operation is not easy to realize, and the requirement of continuous and stable production of dry quenching is difficult to meet.
