JOINT DOUBLE PRESSING DEVICE FOR CONNECTING AUGER DRIVE UNIT

摘要

The present invention relates to a joint double-pressing device for connecting an auger drive unit. According to the present invention, in the auger drive unit having a joint for connecting excavating rods including a plurality of connecting rods and a plurality of stretching rods installed and connected vertically in an upper side of the excavating rods which excavate the ground in a depth longer than a vertical length of a leader vertically installed on the ground and male and female joints mounted with a sealing packing for connecting each of the connecting rods and the stretching rods, a packing pressing device which flexibly presses the sealing packing is installed such that the sealing packing mounted between the male and female joints in the joint for connecting the excavating rods seals between the male and female joints to maintain a sealed state. The packing pressing device comprises: a spring case inserted into the female joint, in which an outer lower latching projection is latched with an inner upper latching projection; a plurality of assembling bolts in which an assembling end where a male screw is formed is inserted and installed through a plurality of assembling holes formed at a certain interval in an upper flange of the spring case; a packing sheet assembled in close contact with a lower part of the spring case such that each assembling end of the plurality of the assembling bolts is screw-assembled; and a plurality of springs elastically installed between the upper flange of the spring case and the upper face of the packing sheet while wrapping each of the plurality of the assembling bolts.
