Abstract
The utility model provides a quick bolt wedge type tension-endurable wire clamp which mainly solves the problem that the installation of the present tension-endurable wire clamp is inconvenient as toa line circuit with large gripping force and large span. The tension-endurable wire clamp is characterized in that a wire clamp main body (1) is composed by the connection of two bodies alike in a clamping manner, a dovetail groove and a tenon which are mutually connected in inosculating and clamping manners are arranged at the butt-jointing rim, the inner wall at the connecting position is semi-circular arc-shaped after the two bodies of the wire clamp main body (1) are butt-jointed, a wedge core (2) which also comprises two symmetrical bodies is arranged in the wire clamp main body (1), thewedge core (2) is inosculated and clamped with the connecting position of the wire clamp main body (1), and a circular hole channel is formed at the opposite position of the wedge core (2). With the characteristics of convenient installation, high installation speed, repeated using and low cost, the quick bolt wedge type tension-endurable wire clamp can be used in the line circuit with an insulating steel core aluminum twisted wire.
Description
Technical field:
The utility model relates to employed a kind of gold utensil in the electric power transportation art, is specifically related to a kind of strain clamp that can carry out Fast Installation to overhead power line, and the quick bolt wedge type strain clamp of big grip, large span circuit especially can be provided.
Background technology:
Strain clamp is that electric power is carried stringing a kind of gold utensil of usefulness often, is used for fixing lead, bearing wire tension, and lead fixed is being suspended on gold utensil on the straight line pole on the insulator string or with lightning conducter.At present, the strain clamp used of overhead power line can be divided into: screw bolt-type, wedge type, compression-type, preformed armor rods type.Screw bolt-type, wedge type and preformed armor rods type generally are used for, the lead of little grip, for big grip, then adopt compression-type than large span.But use the compression-type strain clamp, it is very inconvenient that circuit is installed, and must the specific hydraulic instrument, can not carry out secondary after strain clamp uses uses, have electric contact point, added the danger of circuit operation, especially the steel reinforced aluminium conductor infringement to tape insulation is bigger.
The utility model content:
In order to overcome disadvantages of background technology, the utility model provides a kind of quick bolt wedge type strain clamp, this quick bolt wedge type strain clamp has mainly solved existing strain clamp and for big grip, large span circuit inconvenient problem has been installed, can be used in the circuit of tape insulation steel reinforced aluminium conductor, have easy for installation, installation rate fast, can reuse and characteristics that cost is low.
The technical solution of the utility model is: this quick bolt wedge type strain clamp comprises wire clip body, wedge core and link plate, wire clip body and wedge core are wedge shape in the vertical, wire clip body is connected with link plate, wire clip body is that two identical body clampings form, its abutting edge has the dovetail groove and the tenon of the clamping that coincide mutually, interface inwall after the two bodies butt joint of wire clip body is a semicircular arc, the wedge core also is two bodies of symmetry and places in the wire clip body, the wedge core coincide with the interface of wire clip body and blocks mutually, and wedge core opposite position forms circular duct.
Described wedge core is linear pattern or arc line type.
At least fix a briquetting on the described wedge core.
Be connected with hexagon-headed bolt on the described briquetting.
Be connected with hexagonal headband pin-and-hole bolt and axle between described 2 link plates, on the hexagonal headband pin-and-hole bolt hex nut and closed pin arranged, there is closed pin at the axle two ends.
The arc-shaped surface of the contact position of described wedge core and wire clip body scribbles lubricating oil.
The utlity model has following beneficial effect: owing to take such scheme, wire clip body is formed by two, and lead does not need when installing to cut off, and does not have electric contact point in junction like this; Carry out interlocking by semi arch between wedge core and the wire clip body, improve the usage safety performance of product so greatly; The contact-making surface of wedge core and wire clip body is a wedge shape, so only can be the trend that strengthens to the grip of lead, have improved the fail safe of circuit operation; Easy for installation, need not use specific purpose tool, installation rate improves, and line maintenance is also convenient, can also reuse after the circuit dismounting; Can be equipped with the wedge core of different model according to different grip demands, reduce the cost of circuit.The utility model can be used in the circuit of tape insulation steel reinforced aluminium conductor.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is vertical views of Fig. 1;
Accompanying drawing 3 is that the A-A structure cutaway view of Fig. 2 is to view.
1-wire clip body among the figure, 2-wedge core, 3-link plate, 4-briquetting, 5-hexagon-headed bolt, 6-hexagonal headband pin-and-hole bolt, 7-axle, 8-hex nut, 9-closed pin, 10 leads.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this quick bolt wedge type strain clamp comprises wire clip body 1, wedge core 2 and link plate 3, wire clip body 1 is wedge shape in the vertical with wedge core 2, wire clip body 1 is connected with link plate 3, wire clip body 1 forms for two identical body clampings, its abutting edge has the dovetail groove and the tenon of the clamping that coincide mutually, interface inwall after the two bodies butt joint of wire clip body 1 is a semicircular arc, wedge core 2 also is two bodies of symmetry and places in the wire clip body 1, wedge core 2 coincide with the interface of wire clip body 1 and blocks mutually, and wedge core 2 opposite positions form circular duct.Because wire clip body 1 is formed by two, lead 10 does not need to cut off when installing, there is not electric contact point in junction like this, between wedge core 2 and the wire clip body 1 is to carry out interlocking by semi arch, improved the usage safety performance of product, wedge core 2 is a wedge shape with the contact-making surface of wire clip body 1, so only can be the trend that strengthens to the grip of lead 10, have improved the fail safe of circuit operation.Easy for installation, need not use specific purpose tool, installation rate improves, and line maintenance is also convenient, can also reuse after the circuit dismounting, can be equipped with the wedge core 2 of different model according to different grip demands, has reduced the cost of circuit.
Described wedge core 2 is a linear pattern, also wedge core 2 can be made into arc line type according to actual needs.
At least fix a briquetting 4 on the described wedge core 2, the quantity of briquetting 4 determines that according to the length of wedge core 2 briquetting 4 can make wedge core 2 chucking leads 10.
Be connected with hexagon-headed bolt 5 on the described briquetting 4, unclamp or fastening convenience.
Be connected with hexagonal headband pin-and-hole bolt 6 and axle 7 between described 2 link plates 3, on the hexagonal headband pin-and-hole bolt 6 hex nut 8 and closed pin 9 arranged, there is closed pin 9 at axle 7 two ends.
Described wedge core 2 scribbles lubricating oil with the arc-shaped surface of the contact position of wire clip body 1, reduces the coefficient of friction between wedge core 2 and the wire clip body 1, is beneficial to wedge core 2 chucking leads 10.
During actual the use, it is middle that lead 10 is put into two wire clip bodies separately 1, then the dovetail groove of 2 wire clip bodies 1 and tenon are aligned in advance and link, wedge core 2 is put into wire clip body 1, the semi arch of wedge core 2 pins two wire clip bodies 1 and draw close to the centre, utilize the deadweight of lead 10 can make the powerful grip of generation between lead 10, wedge core 2 and the wire clip body 1 like this, finish installment work.The utility model can be used in the circuit of tape insulation steel reinforced aluminium conductor.
