The utility model discloses an integrated derrick of an under-pressure operation machine. The integrated derrick comprises a prying frame, a wellhead support, a main operation table, an auxiliary operation table, an upper base plate, a lower base plate and hydraulic cylinder stand columns. The upper base plate is fixedly connected to the top of the prying frame, the lower base plate is fixedly connected to the middle of the prying frame, the two ends of the four sets of hydraulic cylinder stand columns are fixedly connected with the upper base plate and the lower base plate respectively, the top end of the wellhead support is fixedly connected with the lower base plate, and the side face of the bottom end of the wellhead support is fixedly connected with the bottom of the prying frame. The prying frame, the well mouth support, the upper base plate, the lower base plate and the four sets of hydraulic cylinder stand columns form a rigid frame body of the integrated derrick. Most load or all load of the under-pressure operation machine can be transmitted to the prying frame and the well mouth support to be borne, and the potential safety hazard that an original well mouth device is crushed due to the fact that the original well mouth device bears large load is fundamentally eliminated; and the problem of deformation and leakage of the sealing ring of the connecting flange caused by alternating load is fundamentally solved.

This invention discloses a scaffold connector for easy disassembly of tall formwork structures, comprising uprights, horizontal bars, vertical diagonal bars, a movable hinge plate, and a connecting plate. The uprights and horizontal bars are connected by the connecting plate. The front end of the connecting plate has six connecting teeth, and the inner edge of the connecting plate has three V-shaped connecting hooks. The front end of the horizontal bar includes six horizontal bar protrusions and three diamond-shaped connecting hooks. The horizontal bar protrusions connect with the connecting teeth, and the diamond-shaped connecting hooks connect with the V-shaped connecting hooks. The movable hinge plate is connected to the horizontal bar, and its upper and lower ends are threaded to the diagonal bars. This scaffold connector, through the rational arrangement of the structure of each component, reduces the local pressure on the connecting plate, and the connecting plate and the horizontal bar can be quickly connected or disassembled using a simple push-pull engagement.
