[embodiment]
The technical scheme of accompanying drawing to the embodiment of the present invention below in conjunction with the embodiment of the present invention is explained and illustrated, but following embodiment is only the preferred embodiments of the present invention, and not all.Based on the embodiment in execution mode, those skilled in the art under the prerequisite not making creative work obtain other embodiments, all belong to protection scope of the present invention.
As shown in Figure 1; protection of arrester framework in the preferred embodiment of the present invention comprises upper frame 1, underframe 2 and insulating bar 3; insulating bar 3 is connected between upper frame 1 and underframe 2; framework 1 is provided with snap ring 4; movable rod 11 is connected with between snap ring 4 and upper frame 1; underframe 2 is fixedly connected with ring holder 21, and ring holder 21 is provided with fixture.
As in Figure 2-4, upper frame 1 in the preferred embodiment of the present invention is circular, external screw thread 31 has been attacked at the two ends of insulating bar 3, upper frame 1 is provided with upper screwed hole 12 and is connected otic placode 13 with first, snap ring 4 comprises the card 41 of three arcs, the two ends of card 41 are outwards bent to form mounting ear 411, the second connection otic placode 42 is also provided with at the middle part of card 4, the outer end of movable rod 11 is connected otic placode 13 with first and is bolted, the inner is connected otic placode 42 with second and is bolted, movable rod 11 can drive card 41 in the vertical direction centered by the outer end of movable rod 11 to do half circular motion, the inwall of card 41 is also provided with rubber blanket 43, damage is crushed to prevent snap ring 4 pairs of lightning arresters when clamping lightning arrester upper end from causing.When Figure 3 shows that snap ring 4 closes, be bolted to connection between two now adjacent mounting ears 411, when Figure 4 shows that snap ring 4 is opened, now separated state between adjacent two mounting ears 411, can by the upper end of lightning arrester from removal in snap ring 4 with this.
As seen in figs. 5-6, underframe 2 is circular, underframe 2 is provided with lower screwed hole 22, ring holder 21 is provided with fixture and fixed block 221, fixture comprises two groups of clamping parts, wherein clamping part comprises adjusting bolt 51 and grip block 52, fixed block 221 is provided with through hole, one end of adjusting bolt 51 is passed through hole and is connected with grip block 52, after installation, the clamping part in left side and the clamping part on right side form grasping part 6, during zinc oxide surge arresters, the lower end of lightning arrester is positioned at grasping part 6, the adjusting bolt 51 of rotating both sides is close and clamp the lower end of lightning arrester to center position to promote sandwich block 52, lower end due to lightning arrester is smooth cylinder, thus after clamping, the lower end of lightning arrester can occur to slide thus depart from fixture, in order to strengthen the fastness of holder lightning arrester, the inwall of grip block 52 is also provided with stepped tooth 521.
As shown in Figure 3 and 7, upper frame 1 is also arranged with two hangers 14, hanger 14 is provided with perforation 141, protection of arrester framework is articulated on boom hoisting by hanger 14, is beneficial to the lifting of lightning arrester when removing and installing.
To install zinc oxide arrester, first by rotating movable rod 11, the snap ring 4 on upper frame 1 being pulled to open mode, being inserted in zinc oxide arrester from the bottom up, closing snap ring 4, making by tighting a bolt snap ring 4 block the upper end of zinc oxide arrester; Secondly zinc oxide arrester lower end is inserted in the installing space 6 of underframe 2, rotate underframe 2, upper screwed hole 12 is aimed at respectively with lower screwed hole 22, and the two ends of insulating bar 3 are screwed in respectively in upper screwed hole 12 and lower screwed hole 22, insulating bar 3 can carry out length adjustment within the specific limits to adapt to the zinc oxide arrester of different length, versatility is comparatively strong, and dismounting and installation are simply.The lower end of zinc oxide arrester is fixed to make two grip blocks 52 by the adjusting bolt 51 of then tightening on fixture.By lifting rope through the perforation 141 on hanger 14, hang on boom hoisting, the jockey on dismounting zinc oxide arrester top, protection of arrester framework is adjusted to ground together with zinc oxide arrester by boom hoisting subsequently, tests.Due to the protection of protection of arrester framework, the full skirt portion therefore in unloading process on zinc oxide arrester can not be subject to the destruction of external force, thus ensure that the service behaviour of zinc oxide arrester, extends the useful life of zinc oxide arrester.After off-test; protection of arrester framework is sling to installation site together with zinc oxide arrester, after installing lightning arrester, dismantles underframe, insulating bar and upper frame successively; compared to existing technology, protection of arrester framework of the present invention improves the efficiency of lightning arrester when dismantling and install.
