Furthermore, a fastening bolt for fixing the position of the second wedge-shaped block is arranged on the screw rod.
Further, the jack is arranged between the end plate and the rear end plate.
Before supporting construction, the adjustable steel pipe joints can be made into a series of structures which can meet various length requirements. And during construction, a proper steel pipe joint structure is selected according to the length of the steel pipe. The end of the steel pipe is reliably connected with the steel pipe by the flange. During connection, the stiffening direction in the end of the steel pipe is in a cross shape, and the external stiffness is basically in a horizontal state. Inserting the limiting plate of the bolt piece into the gap of the limiting plate, ensuring the inner stiffening, placing a jack, and operating the jack oil pump to adjust the gap between the end of the steel pipe and the bolt piece to be enlarged or reduced. After the adjustment is in place, the fastening bolt is rotated, so that the two wedge-shaped blocks tightly plug the gap between the two groups of limiting plates, and the self-locking purpose is achieved. And in subsequent adjustment as required, the operation of the jack and the limiting block can be realized.
Compared with the prior art, the utility model is simple in operation, can adjust the interior that the steel pipe supported in a flexible way as required to realize reliable auto-lock, have good practical value.
