Afterwards, again the male cone (strobilus masculinus) 10 of cleat stanchion 2 is inserted in the internal taper hole of connector 3 upper end, under the effect of the gravity of self gravitation and carrying, the male cone (strobilus masculinus) 10 of cleat stanchion 2 is naturally fitted with the inner conical surface 11 of connector 3 and fixes, and the gravity depressed from cleat stanchion 2 is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted; On the male cone (strobilus masculinus) 10 being enclosed within cleat stanchion 2 upper end at the internal taper hole of connector 3 and the male cone (strobilus masculinus) 10 of cleat stanchion 2 insert in the process of Inner taper hole 12, the front end of male cone (strobilus masculinus) 10 enter into the position of locking head and acute angle bevel on oblique promotion locking head time, the front end oblique promotion locking head of male cone (strobilus masculinus) 10 compresses thrust spring 8 and outwards makes a concession, and the front end of male cone (strobilus masculinus) 10 passes through the position of locking head; When the male cone (strobilus masculinus) 10 of cleat stanchion 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of connector 3, annular lock groove 9 on male cone (strobilus masculinus) 10 is right through the position of locking head, locking head enters in annular lock groove 9 under the powered of thrust spring 8, the facing directly of locking head to face directly with the annular of annular lock groove 9 coordinate the inner conical surface 11 of fitting and male cone (strobilus masculinus) 10 locked, male cone (strobilus masculinus) 10 can not be retreated.D, when adopting the cleat stanchion 2 of multilayer to form the upright maintenance ladder of high-tension circuit, repeat on male cone (strobilus masculinus) 10 that connector 3 can be enclosed within cleat stanchion 2 by the step and method of step C again or again the male cone (strobilus masculinus) 10 of another root cleat stanchion 2 inserted in the Inner taper hole 12 of connector 3 below, completing being connected and fixed and locking between cleat stanchion 2 and connector 3.Cleat stanchion 2 is very convenient with the assembling of load bearing seat 1 and cleat stanchion 2 and connector 3, just can complete without any need for instrument.
When the cleat stanchion 2 of dismountable is with connector 3, pull the pin handle of self-lock pin 6, after the locking head of self-lock pin 6 front end exits the annular lock groove 9 on male cone (strobilus masculinus) 10, cleat stanchion 2 or connector 3 upwards one are drawn or one to be lifted, and the male cone (strobilus masculinus) 10 of cleat stanchion 2 will separate automatically with the Inner taper hole 12 of connector 3.During fixing on dismounting load bearing seat 1 cleat stanchion 2, pull the pin handle of self-lock pin 6, after the locking head of self-lock pin 6 front end exits the annular lock groove 9 on male cone (strobilus masculinus) 10, cleat stanchion 2 upwards one is drawn or one to be lifted, and cleat stanchion 2 will separate automatically with load bearing seat 1.Cleat stanchion 2 is very convenient with the dismounting of load bearing seat 1 and cleat stanchion 2 and connector 3, just can complete without any need for instrument.
High-tension line maintenance personal is when examination and repair for high-pressure circuit, run into when having branch Distance High Voltage Electricity Transfer very near or line joint need maintenance time, first holder 16 is placed steadily on the ground, combining holder 16 again, the load bearing seat 1 of the rotatable locking seat of ball and load bearing seat 1 plug first cleat stanchion 2 above after, the cleat stanchion 2 and connector 3 that need height are taken with oneself, pin steps down on the foot hold on cleat stanchion 2 and climbs up, one section of assembling one section can be climbed, when climbing to the top of ladder in the process of cat ladder, climb up again after inserting a cleat stanchion 2 after superincumbent male cone (strobilus masculinus) 10 overlaps upper binding head 3 again.During descending stair, step down on foot hold and down climb, next section tears a cleat stanchion 2 and connector 3 open, very convenient.
