The using method of a kind of 10kV adjustable distribution network overhead line cross-arm eyelid retractor, comprises the following steps:
1) operating personnel is by regulation fastening bolt, side fastening bolt is turned on, and is placed to the suitable of shaft tower below cross-arm
Work as position so that old cross-arm lower limb falls in the cross-arm bracket bracket of side, then regulates both sides fastening bolt by cross-arm bracket
Reliable fixing, then by regulating two bolts of old cross-arm side so that this side guide press old cross-arm top edge so that
Old cross-arm is reliably fixed;
2) remove the U-bolt of old cross-arm, newer cross-arm lower limb is placed in the bracket of opposite side cross-arm bracket, then
Screw bolt, fix new cross-arm by corresponding two pressing plates;
3), after confirming that new cross-arm is reliably fixed on bracket, re-use stay bolt and new and old cross-arm is fixedly connected on shaft tower
On, determine after being reliably connected, by regulation both sides bolt, make two side guides depart from new and old cross-arm top edge, then regulation is tight
Fixing bolt, makes eyelid retractor take off from shaft tower, completes single cross-arm and changes double cross-arm operation.
Compared with prior art, the invention has the beneficial effects as follows:
The most affected by environment, it is particularly suitable for the environment that jack lift cannot arrive;For the temporary support to cross-arm
To simplify work flow, save jack lift messenger wire, former cross-arm separates with three-phase conducting wire and colligation, up and down transmission cross-arm etc. are made
Industry step.This device has draw materials convenience, simple to operate, applied widely, the feature of length in service life.The letter of eyelid retractor structure
Single, easy accessibility, it is simple to transport, on bar, a people gets final product operation.On cross-arm bracket, bracket is set, in order to limit cross-arm position.Logical
Overregulate pressing plate to fix and on cross-arm, and pressing plate, arrange anti-slip veins, prevent cross-arm landing in work progress, it is ensured that cross-arm is firm.
The outer height H of cross-arm bracket is more than interior edge height h, it is possible to limit cross-arm position, it is ensured that cross-arm is the most crooked.Regulation fastening bolt
Realize eyelid retractor to be fixed on shaft tower, and prevent eyelid retractor landing by draw-in groove so that it is be more firmly fixed on shaft tower.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail, it should be noted that the enforcement of the present invention does not limits
In following embodiment.
Seeing Fig. 1, a kind of 10kV adjustable distribution network overhead line cross-arm eyelid retractor, including bolt 1, pressing plate 2, spring
3, fastening bolt 4, cross-arm bracket 5, two cross-arm brackets 5 are symmetrical arranged and pass through the fixing connection of fastening bolt 4, and pressing plate 2 passes through
Bolt 1 is fixed on cross-arm bracket 5;Spring 3 one end is resisted against on pressing plate 2, and the other end is resisted against on cross-arm bracket 5, protects
Card pressing plate 2 and the isolation of cross-arm bracket 5, it is simple to one man operation;Seeing Fig. 3, Fig. 4, pressing plate 2 surface is provided with anti-slip veins 8, to strengthen it
Frictional force with cross-arm;Cross-arm bracket 5 is provided with the draw-in groove matched with shaft tower.
Seeing Fig. 2, wherein, cross-arm bracket 5 is provided with bracket 7, in order to limit the position of cross-arm.Cross-arm bracket 5 and pressing plate 2 are adopted
Make of aluminum alloy materials, in order to alleviate the deadweight of eyelid retractor.
Seeing Fig. 1, the outer height H of cross-arm bracket 5 coordinates bracket 7 more than interior along height h, makes cross-arm more solid
It is scheduled on cross-arm bracket 5, prevents cross-arm from rocking.
Bolt 1, in order to control the distance of pressing plate 2 and cross-arm top edge, reaches fixing cross-arm top edge effect.
The spacing of fastening bolt 4 scalable cross-arm bracket 5, enables eyelid retractor to be arranged on the shaft tower of different-diameter.
Spring 3 makes pressing plate 2 have support force upwards all the time, and when preventing one man operation, pressing plate 2 slides into horizontal stroke under gravity
The inconvenience brought at load bracket 7.
The using method of a kind of 10kV adjustable distribution network overhead line cross-arm eyelid retractor, comprises the following steps:
1) operating personnel is by regulation fastening bolt, side fastening bolt is turned on, is placed to shaft tower position below cross-arm,
Old cross-arm lower limb is fallen in the cross-arm bracket bracket of side, then it is reliably solid by cross-arm bracket to regulate both sides fastening bolt
Fixed, then by regulating two bolts of old cross-arm side so that this side guide presses old cross-arm top edge so that old cross-arm
Reliable fixing;
2) remove the U-bolt of old cross-arm, newer cross-arm lower limb is placed in the bracket of opposite side cross-arm bracket, then
Screw bolt, fix new cross-arm by corresponding two pressing plates;
3) after confirming that new cross-arm is reliably fixed on bracket, re-use stay bolt (screw mandrel and nut combination also can) by new and old
Cross-arm is fixedly connected on shaft tower, determines after being reliably connected, and by regulation both sides bolt, makes two side guides depart from new and old horizontal stroke
Load top edge, then regulate fastening bolt, make eyelid retractor take off from shaft tower, complete single cross-arm and change double cross-arm operation.
During concrete operations, bolt 1 uses M12*80*135 stainless steel bolt, nut.Fastening bolt 4 uses M16*
90*350 stainless steel bolt, nut.
The outer face of cross-arm bracket 5 is provided with groove 6, in order to alleviate the deadweight of cross-arm bracket 5.
On the basis of present invention can be implemented in original single cross-arm, by the way of adding new cross-arm, directly reach operation purpose, save
Go jack lift to go offline, former cross-arm separates with three-phase conducting wire and colligation, up and down the transmission job step such as cross-arm.This device has
Drawing materials conveniently, simple to operate, service life is long, greatly simplifies work flow.
