Description

Technical Field

[0001] This utility model relates to a construction tool, specifically a quick-release tool for fixing a coke oven pre-embedded sleeve. Background Technology

[0002] Large coke ovens, such as 6.78m tamping coke ovens, 7m and 7.65m top-loading coke ovens, have a large number of pre-embedded coke oven sleeves on their foundation top plates. Taking a 2×60-hole JNX3-6.25 type tamping coke oven as an example, there are 61 groups of coke oven lower spray pipes distributed longitudinally along the coke oven, with 36 pipes in each group distributed transversely, totaling 2196 pipes; there are 128 groups of coke oven cleaning pipes distributed longitudinally along the coke oven, with 20 pipes in each group distributed transversely, totaling 2560 pipes.

[0003] During the actual on-site installation of the coke oven foundation roof sleeve, after the coke oven pre-embedded sleeve was in place, L50×5 angle steel was used to spot weld and fix each set of lower spray pipes and cleaning pipes longitudinally, and 10# channel steel (center fixed) and L50×5 angle steel were used to reinforce the fixing frame transversely. This method accurately positioned the coke oven pre-embedded sleeve, reduced disturbance to the coke oven pre-embedded sleeve during construction, and improved the installation accuracy of the coke oven pre-embedded sleeve.

[0004] After the concrete pouring and curing are completed, the pre-embedded sleeve fixing frame of the coke oven must be dismantled and recycled, and the foundation top slab must be handed over to the furnace body for masonry. Considering that the angle steel is fixed to each lower spray pipe and cleaning pipe by spot welding during the construction of the fixing frame, the construction process of dismantling the fixing frame is relatively complicated and the dismantling work is time-consuming and labor-intensive.

[0005] Therefore, the known methods for removing fixed cable trays have the aforementioned inconveniences and problems. Utility Model Content
