High voltage live line stringing protector

Abstract

The invention discloses a high voltage live line stringing protector. The high voltage live line stringing protector includes a stay cable and 2 hooks, and also includes a fixed box, wherein the fixed box is a flat hollow box body which is penetrated in the length direction, and the upper end of the fixed box is connected with a hook; a stay cable pulley is arranged in the fixed box; a rotary block revolving shaft is arranged right below the stay cable pulley; the axial direction of the rotary block revolving shaft is the thickness direction of the fixed box; a rotary block is in sleeve joint with the rotary block revolving shaft, and can move freely; the length direction of the rotary block is the left and right direction, and the left and right ends are each provided with an acute angle in the upward direction and the outward direction; a brake block is fixedly arranged at one side of the left and right sides of the fixed box, and the side wall, facing the rotary block, of the brake block, is the external brake wall, and the corresponding wall of the rotary block is the internal brake wall; the external brake wall and the internal brake wall are in clearance fit, and is adaptive in shape; the stay cable enters the box body from the lower end, winds around the stay cable pulley, passes by the clearance between the external brake wall and the internal brake wall, and then returns to the position being below the box body; and the other hook is fixed on the stay cable. The high voltage live line stringing protector has the advantages of being convenient in operation, and being good in the secure effect.

Description

technical field [0001] The invention belongs to the field of electric construction tools, in particular to a high-voltage electrified wire tight protector. Background technique [0002] The overhead transmission lines of high-voltage electricity need to be equipped with ground wires, and the ground wires need to be tensioned. Traditionally, when tightening the ground wire, a wire tensioner is used. For example, the Chinese patent document CN203734217U disclosed on July 23, 2014 "a straight line to tension tensioner for overhead lines", including a fixed bracket, two rope tightening mechanisms, a driving gear, a transmission handle, two traction ropes and two Moving pulley; the two rope tightening mechanisms respectively include a driven gear, a stop ratchet, a ratchet and a rope tightening reel, the rope tightening reel is rotatably installed on a fixed bracket, and the driven gear and the stop ratchet are connected with the rope tightening reel respectively. Coaxial linka...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is that the auxiliary wire tensioner is used as insurance in the existing electric power line tightening construction, which is cumbersome to operate and low in working efficiency, so a high-voltage live line tensioner is provided, which has the advantages of convenient operation and good insurance effect Advantage
