AI Technical Summary
The steel roof of the existing fumigation pool is prone to deform and dislocation during opening and closing, and the sealing effect is poor, resulting in unsatisfactory fumigation effect. At the same time, the operation consumes a lot of manpower and material resources, and it is difficult to recover and dispose of harmful gases.
The lifting mechanism is used to cooperate with the sealed end cover and the electric chain hoist crane. The array of multiple electric chain hoist cranes is distributed on both sides of the sealed end cover to realize the opening and closing of the fumigation pool, ensuring uniform and precise positioning of the force, and using longitudinal sliding fit and roller guide structure to ensure the stable placement of the sealed end cover after opening the cover.
The stable opening and closing of the fumigation pool is achieved, which avoids deformation and misalignment of the sealed end cap, improves the fumigation effect, reduces manpower and material consumption, and solves the problem of recycling and disposal of harmful gases.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of quarantine and pest control of imported wood, and in particular to a roof lifting and opening and closing facility for a large-scale wood fumigation pool. Background Art
[0002] In the past, the fumigation method used tents to cover the open-air fumigation pools, and then compacted the surrounding areas with sandbags. The fumigation pools had a large fumigation processing capacity and were easy to load, but the tents were not airtight and had poor thermal insulation effects. At the same time, there were leaks at the crimping points of some sandbags, and the tents were scratched and damaged when covered, resulting in poor thermal insulation effects. In addition, tent fumigation required a lot of manpower and material resources, including covering, compacting, sealing, and inspecting the log fumigation pools. After fumigation, methyl bromide, as a harmful gas that has adverse effects on the human body and the environment, its recovery and disposal has always been a headache for management personnel.
[0003] At present, the better way is to add a steel roof to the fumigation tank. Since fumigation tanks are generally large, the volume of the tank will also be larger with an integral roof. After fumigation, in order to facilitate the loading and handling of wood, the steel roof needs to be opened as a whole. However, how to ensure that the fumigation tank cover does not deform during the opening process, and can be covered back on the fumigation tank after the wood is transported, and how to place the fumigation tank cover after opening has always been a problem that has plagued customs quarantine fumigation operators.
