The invention discloses a large-tonnage crane binding type rigging, which relates to the technical field of rigging, and includes a support platform, a work object, and a binding mechanism installed on the support mechanism. The binding mechanism includes an actuator, a lifting mechanism and a fixed installation On the mounting plate on the fixed plate, the first gear and the third gear are installed in rotation on the mounting plate, the first gear and the third gear mesh with each other, the second gear is fixedly installed on the first gear, the second gear and the fourth gear Mutual meshing, the fourth gear and the fifth gear are fixedly connected, the fifth gear is rotatably installed on the fixed plate, the fifth gear and the wide rack are meshed with each other, the wide rack is fixedly installed with an indexing rack, and the wide rack is set There is a sliding groove, and a slider is slidably installed in the sliding groove, and the slider is fixedly installed on the mounting plate to bind the work objects. The invention binds the large-tonnage work objects through the binding mechanism to carry out stable and safe lifting without manual labor. Hook, stable and reliable.

The invention provides an umbilical cord binding device. The umbilical cord binding device comprises a binding band, a connector at one end of the binding band is installed at a through hole formed in the top end of an outer casing pipe, a clamping sleeve is connected in the outer casing pipe, a blade is fixed at the opening end of the clamping sleeve, a binding band handle is slidably assembled in the clamping sleeve, and the other end of the binding band is connected to the binding band handle to form a whole. The size of the binding band and the binding band ring can be directly regulated without needing to enable the hand to make contact with the umbilical cord in the use process, cross infection is avoided by regulating the tightness degree of binding the umbilical cord through the binding band, use is convenient, time and labor are saved, and the use effect is better. The umbilical cord binding device has the self-locking function except the functions of regulating the tightness of binding the umbilical cord and being fixed at the appropriate position, the umbilical cord can be separated from the binding device as long as a binding band handle is pulled to screw tightly an outer casing pipe and the binding band is cut off with a blade, then an accident that the physical health of a newborn is influenced by umbilical cord wound surface infection due to the fact that the umbilical cord is not bound tightly is completely eradicated, the umbilical cord head is facilitated to drop earlier, and therefore the separation time of the umbilical cord head is greatly shortened; according to the device, it is guaranteed that the umbilical cord of the newborn is bound firmly and nursed safely.

The invention relates to an auxiliary binding device, in particular to a clamping device for auxiliary binding of steel bars. The technical problem is how to design a kind of clamping device for auxiliary binding of steel rings that can be used to stabilize the steel rings without manpower when bundling, save manpower, and can compact the steel rings when bundling.
