Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-4, the post-support for live replacement of a bottle holder for a 110kV single tension string insulator comprises a connecting rod 1, a first nut 2 and a second nut 3 arranged on the upper portion of the connecting rod, a bayonet 4 arranged at the tail end of the connecting rod, and a clamping structure arranged at the bayonet 4.
The bayonet 4 includes planking 5 and inner panel 6, the n type open structure that inner panel 6, planking 5 and connecting rod 1 enclose, and the chucking structure includes fixed urceolus 7, the cover is established in fixed urceolus 7, can be at the gliding kelly 8 of fixed sleeve 7, and the lateral surface at planking 5 is fixed to the one end of fixed urceolus 7, and the other end is equipped with roof 9, offers the through-hole that can make kelly 8 pass through on planking 5. An adjusting groove 10 is formed in the fixed outer cylinder 7, an adjusting rod 11 matched with the adjusting groove 10 is arranged on the clamping rod 8, and the clamping rod 8 is connected with the top plate 9 through a spring 12.
The adjusting rod 11 is clamped and fixed to different positions of the adjusting groove 10, so that the clamping rod 8 abuts against the inner wall of the inner plate 6 or retracts into the fixed outer cylinder 7. In order to enable the tail end of the bottle supporting frame to be firmly clamped in the bayonet 4, a through hole corresponding to the clamping rod 8 can be formed in the inner plate 5, so that the clamping rod sequentially penetrates through the through hole of the outer plate 6, the hole at the tail end of the bottle supporting frame and the through hole of the inner plate 5, and the tail end of the bottle supporting frame is firmly clamped in the bayonet 4. The clamping rod 8 is telescopically connected with the fixed outer cylinder 7 through a spring 12, an adjusting groove 10 and an adjusting rod 11.
As a preferred technical scheme, the tail end of the clamping rod 8 is provided with an inclined opening, when the bottle supporting frame supporting plate needs to be clamped into the clamping opening 4, an operator holds the bottle supporting frame to lift upwards along the clamping opening 4, and under the action of the inclined opening, a hole in the tail end of the bottle supporting frame is clamped and fixed through the clamping rod 8.
The process demonstration of clamping the bottle supporting frame supporting plate by the clamping rod 8 is as follows:
under normal conditions, the clamping rod 8 bears the acting force of the spring 9, namely, under the normal state without any external force, the clamping rod 8 has the bevel connection side to prop against the inner plate 6, when the bottle supporting frame is installed, the tail end of the bottle supporting frame (the tail end structure of the bottle supporting frame is shown in the attached drawing 5) is lifted up along the bayonet 4, as the bevel connection is arranged at the front end of the clamping rod 8, the spring is extruded through the tail end metal frame of the bottle supporting frame and the clamping rod, the adjusting rod 11 moves towards 9 along the adjusting groove 10, after the clamping rod 8 enters the hole 17 of the tail end metal frame of the bottle supporting frame, the stress of the spring is released, the adjusting rod 11 moves towards the inner plate 6 along the adjusting groove 10 until the bevel connection end props against the inner plate 9, at the moment, the clamping rod 8 penetrates through the hole 17 of the metal frame of the bottle supporting frame, and the bottle supporting frame can be supported. When the bottle supporting frame is required to be taken out of the support, the adjusting rod 11 is only required to be pressed to move along the adjusting groove 10 to the adjusting groove 9, the oblique opening end of the clamping rod 8 is far away from the inner plate 6 to move towards the outer plate 5, the hole 17 at the tail end of the bottle supporting frame is not shielded by the clamping rod 8, and the bottle supporting frame can be easily taken out of the bayonet 4.
As a preferred technical scheme, roof 9 and fixed urceolus 7 swivelling joint can dismantle, are convenient for install spring 12 and in time change and lose elastic spring, because spring 12's effect simultaneously, can make regulation pole 11 remove in adjustment tank 10, and then realize that kelly 8 supports the inboard of tight inner panel 5 or to roof 9 motion, provide convenience for the quick installation and the demolition of support bottle frame.
