Abstract
The invention relates to a universal clamp for a strain tower lead terminal with a turning pulley for a 500-KV line. The clamp comprises an upper clamp part, a lower clamp part, and a trunnion hanging plate assembly connecting the upper clamp part and the lower clamp part. A first clamp groove is formed in a rear end portion of the upper clamp part by corresponding to an upper end of a lead terminal yoke plate; a second clamp groove is formed in a rear end portion of the lower clamp part by corresponding to the lower end of the lead terminal yoke plate; and locking bolts are arranged in the opening of the first clamp groove and the opening of the second clamp groove respectively. An opening hole for lead screw or pull rod connection is formed in the trunnion hanging plate assembly. When the universal clamp is used for replacing an insulator or an insulator chain, any influence from a yoke plate type, a channel steel specification, a bolt pitch, a pitch or a grading ring can be eliminated; the universality is high; tool assembling can be carried out without the need to dismount the grading ring; and working and equipment safety can be guaranteed.
Description
Technical field
The invention mainly relates to replacing insulator technical field, particularly relate to 500KV line tension tower conductor wire end fixture technical field.
Background technology
There are 14, imperial flat A-wire, mountains and rivers A-wire, mountains and rivers second line etc. the conventional type 500kV alternating current circuit that Liuzhou office of EHV transmission company runs, article 14, circuit has anchor support 906 base, strain insulator string conductor wire end yoke plate model has L-2045, L-2045A, L-2145, L-2145A, L-3045, L-3245, L-3245S, L-3245TS etc. 8 kinds, and the manufacturer of yoke plate is up to 9.The thickness of yoke plate has 24mm, 26mm, 28mm, 30mm, 32mm etc. 5 kinds.Bracing frame has ZCJ-45, ZCJ-45H, ZCJ-45L, ZCJJ-450 etc. 4 kinds, and the interior well width of bracing frame has 120mm, 126mm, 160mm totally 3 kinds, and bracing frame fixed bolt hole is from there being 60mm, 80mm totally 2 kinds, and there is 18mm, 26mm totally 2 kinds in bolt aperture.When changing anchor support bunch of insulator or the 1st, 2 insulators reciprocal, the installation method of conductor wire end hard point instrument generally has 2 kinds: (1) is when there being construction hole on yoke plate, wing clamp is entangled the king-bolt of bowl head yoke plate, utilizes and be bolted on construction hole.The shortcoming of the method: when wing clamp entangles bowl head yoke plate bolt, will be unable to during to change socket-clevis eye change；When removing or install insulator, owing to the nargin that can loosen is only small, it will be difficult to dismounting.(2), on yoke plate when nothing construction hole, remove 2 fixing bolts in channel-section steel on bracing frame, wing clamp is arranged in channel-section steel, utilizes bolt to fix.The shortcoming of the method: owing to bracing frame model is more, the channel-section steel installing wing clamp is diversified in specifications, and differing in the pitch-row of bolt, aperture, it tends to be difficult to finds the wing clamp of coupling, so that there is the situation that wing clamp is special, cause assets to waste.Furthermore, above two method is both needed to be got loose insulator chain by corner block, common practice is to install a coaster bracing frame on coaster additional, coaster is hung on the U-shaped ring of conductor wire end, coaster bracing frame is fixed on yoke plate, and its shortcoming is: there is certain uneven situation during due to coaster stress, and the coaster bracing frame therefore supporting coaster is easier to deformation, and coaster fixing point is relatively low, there is the potential safety hazards such as drag rope abrasion.Further, since grading ring is less with last insulator distance, will be unable to after wing clamp is installed assemble screw mandrel and pull bar, need to remove grading ring can operation, when livewire work, remove grading ring and would potentially result in the voltage's distribiuting imbalance of insulator chain, line security is run and constitutes a threat to.
