The invention provides a locking device and a stand pipe supporting system. The locking device comprises: a housing having an accommodating space therein; the locking plug is arranged in the containing space and can stretch out of the containing space to abut against the stand pipe hanging head; at least two adjusting holes are symmetrically formed in the periphery of the locking plug, and the length of the adjusting holes extends in the axial direction of the locking plug. The sealing element is arranged at the rear part of the locking plug and forms a sealed space with the shell; the connecting pipeline is communicated with the sealed space; the reset elastic assembly comprises an elastic body arranged in the locking plug and a limiting piece arranged corresponding to the adjusting hole, the two ends of the elastic body abut against the locking plug and the front end of the limiting piece respectively, and the rear end of the limiting piece extends out of the adjusting hole and cannot move in the axial direction through limitation of the shell; the locking plug moves towards the front end under the pressure of hydraulic fluid to abut against the stand pipe hanging head to achieve the locking function, and when the hydraulic fluid flows out of the sealed space, the elastic body resets to drive the locking plug to move towards the rear end.

    本发明提供了一种锁紧装置及立管支撑系统。锁紧装置包括:外壳,其内部具有容置空间;锁紧塞,其设置于容置空间内,并能够伸出容置空间与立管悬挂头抵接;锁紧塞外周开设有对称设置的至少两调节孔,调节孔的长度沿锁紧塞的轴向延伸;密封件,其设置于锁紧塞的后部并与外壳形成密封空间;连接管路,其与密封空间相通;复位弹性组件,其包括设置于锁紧塞内部的弹性体以及对应调节孔设置的限位件,弹性体的两端分别抵接锁紧塞和限位件的前端,限位件的后端通过调节孔伸出并通过外壳的限制而无法沿轴向移动;其中,锁紧塞在液压流体的压力下向前端移动而抵接立管悬挂头实现锁紧功能,在液压流体流出密封空间时,弹性体复位而带动锁紧塞向后端移动。
