Abstract
A movable type wire clamp is characterized in that a pair of cantilevers is arranged below a socket in a herringbone manner; the bottom ends of the pair of cantilevers are respectively provided with afixed pulley; and the outer circumference of the fixed pulley is provided with a wire casing. By being applied on an electric power poylon pole, the wire lamp can release an unbalanced tension forcecaused by a lead and a pole tower by automatically adjusting the position when the pole tower descends due to ground settlement, thus ensuring the pole tower to have no tilting and flexure under the condition of ground settlement and be kept at normal running state.
Description
Technical field
The utility model relates to the wire clamp on the transmission line, a kind of subside wire clamp on the regional electric power line pole tower of mining area that is applied in of more specifically saying so.
Background technology
The transmission line in mining area has its particularity, for the trunk supply line that is in the Collapse by Mining zone, along with constantly carrying out that the mining area produces, the face of land large tracts of land around the shaft tower is sunk, cause tower bar knockdown, shaft tower sinking lead generation deformation causes lead to produce unbalanced tensile force; The inclination of the asynchronous and tower bar self that shaft tower and backguy are sunk causes producing the lead unbalanced tensile force along line conductor both sides unbalance stress.
The available technology adopting fixed wire clamps, wire clamp hull, pressing plate and U type screw that its version is made by wrought iron are formed.It utilizes two U type screw clamping platens to make lead fixed in the wire clamp hull, and hull is hung by the link plate that two block plates are stamped to form, and link plate is installed on the hanging scroll of hull both sides, and wire clamp rotation axis and lead are on same axis.Because its hull and lead are installed together by U type screw and pressing plate, grip is bigger, when tilting, the tower bar is subjected to the pulling force between insulator and lead, may cause lead wire and earth wire to be broken, or cause shaft tower to topple over, or the lead wire and earth wire wire clamp drawn bad, this state serious threat the power supply reliability in mining area.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of movably wire clamp is provided, in the hope of reducing shaft tower depression, the inclination uneven pulling force that brings, guaranteeing reliably power supply.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model packaged type wire clamp is " people " font a pair of cantilever is set below the bowl head, is respectively arranged with fixed pulley in the bottom of described a pair of suspended wall, and the excircle of described fixed pulley is set to wire casing.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is applied on the electric power pylon bar, can be when ground settlement causes shaft tower to sink, make out-of-balance force obtain discharging for lead and the stressed unbalanced tensile force that causes of shaft tower by automatic adjustment position, guarantee shaft tower not run-off the straight under the situation of ground settlement, deflection, remained on normal operating condition.
2, application of the present utility model can significantly reduce and repeats to overhaul number of times; Reduce the danger that the operating personnel repeats operation on bar.
3, the utility model is simple in structure, according to striding ship molded lines folder principle design greatly, is convenient to install, and the suspension clamp that can directly lead be connected with insulator replaces with the utility model.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram.
Fig. 2 is the utility model side-looking structural representation.
Number in the figure: 11 bowls of heads, 12 bolts, 13 connecting bolts, 14 fixed pulleys, 15 cantilevers, 16 wire casings.
Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, Fig. 2, the structure setting in the present embodiment is " people " font a pair of cantilever 15 is set below bowl 11, is respectively arranged with fixed pulley 14 in the bottom of a pair of cantilever 15, and the excircle of fixed pulley 14 is set to wire casing 16.
In concrete the enforcement, bowl 11 is fixedly installed on the upper end of cantilever 15 by bolt 12, and pulley 14 is by connecting bolt 13; Be connected the lower end of cantilever 15, cantilever 15 adopts band steels, and this version is easy to use, stablize, and can replace common wire clamp to use.
During use, bowl 11 directly is connected with insulator pin or gold utensil; One phase conductor can directly be placed in the wire casing 16 of fixed pulley 14, and when lead was subjected to unbalanced tensile force, lead can be free to slide in the wire casing 16 of fixed pulley 14, comes balance left and right sides circuit along the lead unbalanced tensile force with this.
During installation, when confirming that shaft tower is in the normal position, the operating personnel is down to lead, carry out every safeguard measure, utilize three strings that insulator string and lead are broken away from, insulator string below simply connected bowl head and suspension clamp are replaced by the utility model packaged type wire clamp, adjust insulator string again, require the insulator string angle of inclination to be not more than 5 ° to the normal position; Carry out the adjustment of lead stockbridge damper then.After above enforcement, under the circuit normal operation, lead does not slide in the wire casing 16 of fixed pulley 14; Under the mining area subsides situation, when wire tension is uneven, form in the wire casing 16 of lead at fixed pulley 14 and slide, to eliminate the lead unbalanced tensile force of transmission line under the situation of subsiding.
