Abstract
A fixed type suspension clamp for big span relates to improvement of fixed type suspension clamps, and comprises a clamp body, a pressing plate, a pressing plate connecting bolt and a hanging plate, wherein a wire containing slot is arranged on the clamp body, the pressing plate presses and fixes line conductors in the wire containing slot through a pressing plate connecting bolt, slot bottoms of the wire containing slot on the clamp body close to two ends are inclined downwards with big curvature transitional arc, and two sets of pressing plates and pressing plate connecting bolts are arranged and are correspondingly arranged on two sides of a central point of the wire containing slot. The fixed type suspension clamp is particularly applicable to metal tools of suspension wires for spanning straight line towers of rivers, lakes and the like with big span, has the advantages of big applicable gear distance, big suspension angle, complicated force and big vertical load, and is used in projects with line conductor static variation pressure.
Description
Technical field
The utility model relates to a kind of electric armour clamp, relates in particular to a kind of improvement of fixed suspension clamp.
Background technology
At present, in the power engineering construction, when meeting the circuit of big span, the angle is big because line outlet dangles, the suspension clamp that hangs lead often adopts the mode of the two suspension clamps of two insulator strings to arrange the thing that solves the angle of dangling when design, comes the angle of dangling of a suspension clamp on the compensating wire can not satisfy the problem of the requirement of engineering with two suspension clamps.Whole serial type is often very complicated when designing like this, and installation is extremely inconvenient, and parts is many, and iron tower is stressed big.
The utility model content
The utility model is at above problem, and provide a kind of and be applicable to that span is big, big, the stressed complexity in the angle of dangling, environment that vertical load is big, and the big leap fixed suspension clamp that can the big span circuit of independent bearing requires.
The technical solution of the utility model is: comprise wire clip body, pressing plate, pressing plate connecting bolt and link plate, wire clip body is provided with the appearance wire casing, described pressing plate presses solidly lead in holding wire casing by the pressing plate connecting bolt, appearance wire casing on the described wire clip body is downward-sloping with the deep camber transition arc near the bottom land at place, two ends, described pressing plate, pressing plate connecting bolt are provided with two covers, and correspondence is arranged on holds wire casing mid point both sides.
Described appearance wire casing is near level between the place, two ends.
The length of wire clip body of the present utility model is greater than present common wire clamp length, two wire clamp pressing plates are distributed in the both sides, middle part of wire clip body respectively, with four U-bolts pressing plate and body are coupled to one, can bear the big load of normal operation designing requirement, and can keep its primary characteristic for a long time, the utility model can bear bigger vertical load, can satisfy the instructions for use of big leap with transmission line.The utility model is specially adapted to cross over the river, river, lake isoline tower of the big span gold utensil with hanging wire, has that suitable span is big, big, the stressed complexity in the angle of dangling, and vertical load is big, be used for the big engineering of the quiet transformation power of lead.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is wire clip body among the figure, the 2nd, and pressing plate, the 3rd, the pressing plate connecting bolt, the 4th, link plate, the 5th, hold wire casing.
Embodiment
The utility model as shown in Figure 1, comprise wire clip body 1, pressing plate 2, pressing plate connecting bolt 3 and link plate 4,, wire clip body 1 is provided with and holds wire casing 5, described pressing plate 2 presses solidly lead in holding wire casing 5 by pressing plate connecting bolt 3, appearance wire casing 5 on the described wire clip body 1 is downward-sloping with the deep camber transition arc near the bottom land at place, two ends, described pressing plate 2, pressing plate connecting bolt 3 are provided with two covers, and correspondence is arranged on holds wire casing 5 mid point both sides.Described appearance wire casing 5 is near level between the place, two ends.
When making suspension clamp of the present utility model; select two high-strength aluminum alloy pressing plates, four U-bolts, a spheroidal graphite cast-iron body and a UB link plate for use; the body radius of curvature is 42 times of lead; the angle of dangling is not less than 35 ° (conventional wire clip body dangles the angle for being not less than 25 °), and guardwire is not injured better.Wire clamp adopts two pressing plates fastening to the grip of lead, and grip is big, and product has the angle of dangling greatly, satisfies big overhead crossing engineering requirement.
Claims (2)
1. cross over and use the fixed suspension clamp for one kind big, comprise wire clip body, pressing plate, pressing plate connecting bolt and link plate, wire clip body is provided with the appearance wire casing, described pressing plate presses solidly lead in holding wire casing by the pressing plate connecting bolt, it is characterized in that, appearance wire casing on the described wire clip body is downward-sloping with the deep camber transition arc near the bottom land at place, two ends, and described pressing plate, pressing plate connecting bolt are provided with two covers, and correspondence is arranged on holds wire casing mid point both sides.
2. a kind of big leap fixed suspension clamp according to claim 1 is characterized in that, described appearance wire casing is near level between the place, two ends.
