Description
Technical Field
The utility model belongs to the technical field of chemical tower festival hoist and mount frock, especially, relate to a hoist for chemical tower festival.
Background
In chemical engineering construction, the number of rectifying device towers is large, part of the towers are assembled by flanges due to process maintenance requirements, the length of a general tower section is 4-8 m, the diameter of the general tower section is 1.6-4 m, the single weight of the tower section is 12T-29T, the whole assembled tower can reach 50-80 m, and the whole weight is about 80-200T.
Disclosure of Invention
The utility model aims at providing a hoist for chemical tower festival has the lug of lifting by crane on making the tower festival through using this hoist, and simple structure avoids lifting by crane various risks in the operation.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides a hoist for chemical industry tower section, sets up in the board-like lug at steel connecting plate center including setting up in the steel connecting plate at tower section top, steel connecting plate is equipped with a plurality of screws with tower section junction, steel connecting plate is through wearing to locate the bolt in the screw and the flange fixed connection at tower section top.
Furthermore, still be equipped with two strengthening ribs on the connecting steel plate, the strengthening rib is right triangle, and two strengthening ribs are located the board-like lug left and right sides respectively and with board-like lug and connecting steel plate respectively fixed weld.
Furthermore, a plurality of screw holes on the connecting steel plate are arranged in an arc shape, and each screw hole is in one-to-one correspondence with a flange screw hole on the tower section.
The utility model has the advantages that:
