In order to ensure that supporter is all the time perpendicular to horizontal plane, adopt lock bolt 18 to produce frictional force by rotation forces rotation seat 1 and ear seat 17 and fix rotation seat 1 and the angle angle of bearing 16, when bearing 16 is arranged on the ground of inclination, ensure that the supporter be arranged on rotation seat 1 remains perpendicular to horizontal plane.

In order in use can Rapid Combination and facilitate pin to step on, described supporter be combined into global facility with foot-operated 13, can assembly fast when being beneficial to use; Described foot-operated 13 fixing employing pin on supporter are connected and fixed, and foot-operated 13 one end be merely able on supporter to connector 3 are drawn, downward landing when pin is stepped down on foot-operated 13.

The assemble method of high-tension circuit maintenance ladder: during assembling, A, place the bearing 16, ear seat 17, rotational pin 15 and the rotation seat 1 that fit together on the ground, bearing 16 on ground, rotation seat 1 is above, again the lower end of the column 2 having male cone (strobilus masculinus) 10 is inserted in the Inner taper hole 12 of rotation seat 1, under the effect of self gravitation, the male cone (strobilus masculinus) 10 of column 2 is naturally fitted with the inner conical surface 11 of rotation seat 1 and fixes, and the gravity depressed from column 2 is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted, insert in the process of Inner taper hole 12 at the male cone (strobilus masculinus) 10 of column 2, during inner conical surface 11 position that self-locking head enters into, inclined-plane on the oblique promotion self-locking head of inner conical surface 11 makes self-locking head compress thrust spring 8 and outside oblique yielding, when the male cone (strobilus masculinus) 10 of column 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of rotation seat 1, self-locking head just in time enters the position of annular lock groove 9 after slipping over the inner conical surface 11 above annular lock groove 9 smoothly, self-locking head enters in annular lock groove 9 under the powered of thrust spring 8, to coordinate with the inner conical surface 11 of fitting with the locking face of the annular lock groove 9 of V-arrangement and male cone (strobilus masculinus) 10 is locked can not retreat by facing directly of self-locking head, complete the fixing and locking of supporter and rotation seat 1.B, move the upper end of supporter of inserting rotation seat 1 and make column 2 perpendicular to horizontal plane, lock bolt 18 again on rotational pin 15 compresses rotation seat 1, rotation seat 1 untie-sell 15 that can not rotate is rotated, then make all supporters on rotation seat 1 all keep perpendicular to horizontal plane, and the angle allowing bearing 16 and rotation seat 1 be formed remain unchanged after being completely fixed.One end of male cone (strobilus masculinus) 10 is again had by another root supporter to insert in the Inner taper hole 12 of connector 3 in Inner taper hole 12 in C, connector 3 again on supporter, under the effect of self gravitation, the male cone (strobilus masculinus) 10 of column 2 is naturally fitted with the inner conical surface 11 of connector 3 and fixes, and the gravity depressed from supporter is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted, insert in the process of Inner taper hole 12 at the male cone (strobilus masculinus) 10 of column 2, during inner conical surface 11 position that self-locking head enters into, inclined-plane on the oblique promotion self-locking head of inner conical surface 11 makes self-locking head compress thrust spring 8 and outside oblique yielding, when the male cone (strobilus masculinus) 10 of column 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of connector 3, self-locking head just in time enters the position of annular lock groove 9 after slipping over the inner conical surface 11 above annular lock groove 9 smoothly, self-locking head enters in annular lock groove 9 under the powered of thrust spring 8, to coordinate with the inner conical surface 11 of fitting with the locking face of the annular lock groove 9 of V-arrangement and male cone (strobilus masculinus) 10 is locked can not retreat by facing directly of self-locking head, when the supporter composition of D, employing multilayer prunes gardens special-purpose ladder, repeat the male cone (strobilus masculinus) 10 again inserting column 2 in the Inner taper hole 12 of supporter upper end of step C, afterwards, the male cone (strobilus masculinus) 10 of supporter can insert in the Inner taper hole 12 of a supporter below by Using such method again, completes being connected and fixed and locking between supporter and supporter.The assembling of supporter and rotation seat 1 and supporter and supporter is very convenient, just can complete without any need for instrument.

The method for dismounting of high-tension circuit maintenance ladder: during the supporter of dismountable, pull the pin handle of self-lock pin 6, after the self-locking head of self-lock pin 6 front end exits the annular lock groove 9 on inner conical surface 11, supporter upwards one is drawn or one lifts and automatically will separate with the Inner taper hole 12 in the connector 3 of the supporter of below, and the male cone (strobilus masculinus) 10 of supporter will separate automatically with the Inner taper hole 12 of the connector 3 of the supporter of below.During the supporter that dismounting rotation seat 1 is fixed, pull the pin handle of self-lock pin 6, after the self-locking head of self-lock pin 6 front end exits the annular lock groove 9 on male cone (strobilus masculinus) 10, supporter upwards one is drawn or one lifts and automatically will separate with the Inner taper hole 12 of rotation seat 1, and supporter will separate automatically with rotation seat 1.The dismounting of supporter and rotation seat 1 and supporter and supporter is very convenient, just can complete without any need for instrument.

During high-tension line maintenance personal examination and repair for high-pressure circuit, run into when having branch Distance High Voltage Electricity Transfer very closely to need to prune or when line joint needs to overhaul, first the bearing 16 fitted together, ear seat 17, rotational pin 15 and rotation seat 1 are placed on the ground, after rotation seat 1 is plugged first supporter, the upper end of moving the supporter inserting rotation seat 1 makes column 2 perpendicular to horizontal plane, screw lock bolt 18 again and compress rotation seat 1, rotation seat 1 untie-sell 15 that can not rotate is rotated, then makes all columns 2 on rotation seat 1 all keep perpendicular to horizontal plane; Again needing the supporter of height to take with oneself, pin steps down on foot-operated 13 on supporter and climbs up, one section can be climbed and assemble the supporter that a length of tape has foot-operated 13 again, when climbing to the top of ladder in the process of cat ladder, climb up again after inserting a supporter in superincumbent Inner taper hole 12 again.When having pruned descending stair after branch, pin has stepped down on foot-operated 13 and has down climbed, and next section tears a supporter open, very convenient.
