Description
Technical field
The utility model relates to a kind of cross-arm bracket.
Background technology
Cross-arm is one of material the most basic on overhead power line, and main effect supports power line, and its scope used is wide, frequency is high, change cross-arm, new clothes cross-arm operation very many.When electric power operation repair changes cross-arm, the following two kinds of methods of main employing.First method
,personnel step on bar and change cross-arm: need two people to carry out, be placed on by cross-arm on safety belt, unsafe; Dismounting adjustment needs to hold with hand steered, and personnel are more painstaking; Required time 30 minutes.Second method utilizes high-altitude operation vehicle to change cross-arm, needs to help cross-arm itself with arm, and human body bears moment and strengthens, and dismounting adjustment is more painstaking, easily falling from high altitude occurs.Required time 30 minutes.
Utility model content
The utility model is the problems referred to above that will solve prior art existence, and provide a kind of structure simple, easy accessibility, operating efficiency is high, and labour intensity is low, and coefficient of safety is high, and on bar, a people gets final product the cross-arm bracket of operation.
Technical solution of the present utility model is:
A kind of cross-arm bracket, comprise the square steel tube of two parallel placements in front and back, square steel tube is provided with stretch upwards by frame, the inner side of each square steel tube be provided with about two arrange hold out against frame, one end that two square steel tubes are corresponding is hinged with on two, the connecting plate that lower dislocation is arranged, two connecting plates are provided with multiple link position adjusting hole, in two corresponding up and down adjusting holes, connecting bolt and nut are installed, leading screw is provided with at two square steel tube opposite sides, the rear end of leading screw is hinged on square steel tube below, one end of the corresponding leading screw of square steel tube before described has gap, described leading screw front portion is inserted in gap, screw thread is provided with in the front portion of leading screw, by screw thread, locking nut is installed, by locking nut adjustment to the distance between two square steel tubes that should hold.
The described frame that holds out against is right-angled triangle, and the right-angle side holding out against frame be positioned on same square steel tube is relative.
The beneficial effects of the utility model are: structure is simple, easy accessibility, flexible operation, and wire is regular, and greatly reduce the labour intensity of operating personnel, operating efficiency is high, and the replacing cross-arm activity duration foreshortened to 15 minutes by 30 minutes; Fail safe is good, and avoid because of mismate generation cross-arm case accident, on bar, a people gets final product operation, decreases operating personnel on bar.
Accompanying drawing explanation
Fig. 1 is the structural representation of cross-arm bracket of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure: square steel tube 1,2, by frame 3, hold out against frame 4, connecting plate 5, connecting bolt 6, leading screw 7, locking nut 8, gap 101, adjusting hole 501.
Embodiment
The cross-arm bracket that relates to of the utility model as shown in the figure, comprise the square steel tube 1 of two parallel placements in front and back, 2, at square steel tube 1, 2 be provided with stretch upwards by frame 3, the inner side of each square steel tube 1 be provided with about two arrange hold out against frame 4, one end of two square steel tube 1 correspondences is hinged with on two, the connecting plate 5 that lower dislocation is arranged, two connecting plates 5 are provided with multiple link position adjusting hole 501, in two corresponding up and down adjusting holes 501, connecting bolt 6 and nut are installed, leading screw 7 is provided with at two square steel tube 1 opposite sides, the rear end of leading screw 7 is hinged on square steel tube 2 below, one end of the corresponding leading screw 7 of square steel tube 1 before described has gap 101, described leading screw 7 front portion is inserted in gap 101, screw thread is provided with in the front portion of leading screw 7, by screw thread, locking nut 8 is installed, two square steel tubes 1 to holding are adjusted by locking nut 8, distance between 2.
The described frame 4 that holds out against is for right-angled triangle, and the right-angle side holding out against frame 4 be positioned on same square steel tube is relative.
When adopting this cross-arm bracket to change cross-arm, operating process is as follows:
1, before changing cross-arm, opened by leading screw 7, be enclosed within cement pole by crossbearer bracket, according to cement pole specification, adjustment square steel tube 1,2 corresponding connecting plate 5 side longitudinal separation, connects between two connecting plates 5 with connecting bolt 6 and nut after adjustment;
2, cross-arm bracket is risen to below cross-arm near cross-arm position with insulating cord by personnel on bar, side is made to lean on frame 3 just to below old cross-arm, lock with locking nut 8 in the gap 101 again leading screw 7 being loaded square steel tube 1 above, make to hold out against frame 4 and block cement pole tightly;
3, new cross-arm to be reached on cross-arm bracket with insulating cord and lean against opposite side by frame 3, new cross-arm being arranged on this side by the i.e. old cross-arm opposite side of cement pole above frame with anchor ear, fixing wire;
4, old cross-arm is pulled down, to be placed on cross-arm bracket and lean against immediately below old cross-arm by frame 3; Fasten with insulating cord and old cross-arm is reached ground.
