Elastic element (222), both ends are connect with two claws (221) close to the position of the pin shaft (223) respectively;
L-type buckles (224), one end and a claw (221) hingedly, the other end be set to another described claw (221) bayonet lock (225) mounting on.
10. a kind of UHV transmission line strain insulator monolithic as described in claim 1 replaces platform, it is characterised in that: Crossbeam (11) both ends are arranged with the first sliding sleeve (101) being slidably connected with it, the roof of first sliding sleeve (101) respectively Equipped with the first fastener (105) abutted with the crossbeam (11) top surface, two first fixtures (21) respectively with two institutes The first sliding sleeve (101) is stated to be detachably connected.
11. a kind of UHV transmission line strain insulator monolithic replacing options, which is characterized in that using such as claim 1-10 A kind of described in any item UHV transmission line strain insulator monolithic replacement platforms carry out operation, comprising the following steps:
A. two first fixtures (21) are respectively engaged on two steel caps of same strain insulator string, and ensuring will be more The insulator monolithic changed is stuck in another strain insulator in the middle position of two first fixtures (21), by second fixture (22) On one steel cap of insulator chain;
B. the one end for pressing connection second fixture (22) of the stringer (12) makes the stringer (12) to connect the coaster (4) one end rises to extreme higher position, and keeps stringer (12) fixed, then by the strain insulator monolithic needed to change and the coaster (4) rope connection, removes strain insulator monolithic, and mobile slide assemblies (3) make the coaster (4) be moved to stringer (12) End after, stringer (12) return remains level, and coaster operator controls coaster (4) rope for strain insulator Monolithic is sent to ground, and the stringer (12) are then returned horizontal position and fixation;
C. new strain insulator monolithic is sling to extreme higher position, then by pressing the stringer by the coaster (4) (12) one end for connecting second fixture (22), the one end for making the stringer (12) to connect the coaster (4) increases, until resistance to It opens insulator monolithic and reaches the height being easily installed, the stringer (12) are fixed;
D. position of the slide assemblies (3) on stringer (12) is moved, is moved to the coaster (4) close to strain insulator to be installed The surface of insulator monolithic position is unclamped the drawstring (23), is controlled stringer (12) and is made the one of its connection coaster (4) End slowly decline, is moved to installation site for strain insulator monolithic, retightens the drawstring (23), by strain insulator list Piece is removed and is installed from the coaster (4).
