There is traveling wheel, well type frame A is fixedly connected with the upper end of well type frame B by two cross bars, and the lower end of well type frame A and well type frame B are logical
It crosses two attachment beams to be fixedly connected, the attachment beam and cross bar are arranged in parallel, and cross bar is equipped with multiple hanging rings, and the hanging ring is fixed
On rings seat.
The well type frame A includes two columns being arranged in parallel and the connecting rod being fixed between two columns, and two vertical
A connection short tube is fixed in the upper end of column respectively, and the structure of the well type frame B is identical as the structure of well type frame A, the both ends of cross bar
It is fixedly connected respectively with the connection short tube on the column in well type frame A and well type frame B by latch.
The cross bar is round bar, and the diameter of cross bar is less than the internal diameter of connection short tube.
The jack matched with latch is respectively equipped on the cross bar and connection short tube.
It is set on the cross bar there are three hanging ring, three hanging rings are hung on cross bar respectively.
Rings seat is welded on when replacing blast furnace ore tank scale hooper blanking gate by blanking gate using the utility model
On, blanking gate fixing bolt is then removed, blanking gate will pass through hanging ring hanging on cross bar, flat-pushing well type frame A and well type
Frame B locks blanking gate using hoisting sling, latch of decorporating extracts cross bar out, completes blanking gate after belt holder
Dismantlement work, conversely, realizing the installation of blanking gate.
The beneficial effects of the utility model are: can be in non-stop-machine situation, safe and efficient symmetrical batch box blanking lock
Door is replaced, and overcomes the limitation in field operation space, securely and reliably.
