Description
Technical Field
[0001] This utility model relates to the technical field of support frame for the running track of a coke quenching vehicle, specifically a structure for the expansion joint of the support frame for the running track of a coke quenching vehicle. Background Technology
[0002] The coke quencher is a key piece of equipment in the coking process of a coking plant. Its main function is to intercept coke during the coking process and guide it to the quenching car or coke handling system. This ensures smooth coke transportation, prevents scattering, and protects equipment safety.
[0003] The second running track of the coking plant coke quenching car is an important structure of the coking facility, with a longitudinal length of about 350m. It is usually supported by a reinforced concrete frame structure. In order to reduce structural cracking caused by temperature, seven expansion joints are required in the middle according to the specifications.
[0004] The existing structure involves setting up double rows of columns at the expansion joints, or setting corbels on the columns at the expansion joints, with the track beam simply supported on the corbels. The supporting frame of the second running track of the coke quenching car bears the vertical and horizontal loads of the coke quenching car and the upper dust removal main pipe, resulting in a large column cross-section and a large amount of reinforced concrete. Using double rows of columns at the expansion joints wastes a lot of material. With the conventional structure of setting corbels on columns, to release the temperature effect, the bottom of the beam and the top surface of the corbel slide freely longitudinally; to resist the lateral horizontal thrust of the coke quenching car and the thrust of the dust removal flap valve, it is generally necessary to weld thrust plates onto the embedded parts on the top surface of the corbels. The track beam is relatively high, with a height of 1400-1600mm, resulting in excessive horizontal force transmission and unreasonable torsional stress on the track beam. Alternatively, steel components such as channel steel can be welded onto the frame columns. This method directly transmits horizontal force, but it is prone to hitting the sliding contact frame of the coke quenching car and also affects aesthetics. Utility Model Content

It eliminates the double rows of columns at the expansion joint, reduces the amount of reinforced concrete, avoids collisions with the sliding contact line frame of the coke quenching car, and is simple and beautiful.
