Description
Technical field
The utility model is related to technical field of electric power, especially a kind of crane bar.
Background technology
Taiwan area transformer management is an important process of power supply station, and the rack of each taiwan area transformer supports electric pole
On must all install fall silk tool.Recently it was found that in practical operation, fall during silk tool is removed and often misplace
With fall phenomenon, increase work difficulty and the working time of field personnel, and during falling silk tool and falling, can
The phenomenon that falling the damage of silk tool or even injuring staff by a crashing object can occur, not only increase job costs and along with comparable peace
Full blast danger.
Invention content
The technical problem to be solved by the utility model is to provide a kind of crane bars, fall energy during silk has removing
Enough alignment are limited, and prevent it from falling.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of crane bar, including insulation
Bar is equipped with work head on the top of insulating bar, including fixed seat, the fixed seat are connect by connecting rod with arc-shaped limit card,
Fixed seat is used to fix on arc-shaped limit card and the top of insulating bar, the arc-shaped limit are positioned in the lower section of work head.
Preferably, the fixed seat includes two arc-shaped clips, and one end of two arc-shaped clips is hinged by loose-leaf,
The other end be equipped with mounting hole, by bolt coordinate mounting hole be fixed, the arc-shaped limit card by connecting rod with it is arc-shaped
Clip is fixedly connected.
Preferably, the inside of the arc-shaped clip is equipped with rubber pad.
Preferably, the opening extension rod with outward extension of the arc-shaped limit card.
Preferably, the opening inner side of the arc-shaped limit card is equipped with gag lever post, and gag lever post is articulated on limit base, limit base
It is fixed on the opening inner side of arc-shaped limit card, the limit base is equipped with the limit stops rotated up for placing gag lever post,
The lower section of the gag lever post is equipped with the torque spring for making gag lever post reset.
The utility model provides a kind of crane bar, work head is removed fall silk tool after fall the end of silk tool and hang over work head
On, and slide into arc-shaped limit card, play the role of a limit to falling silk tool, places the swing of its lower end, cause to fall silk
Tool is skidded off from work head.

Fig. 5 falls silk tool for the utility model and falls into the structural schematic diagram after arc-shaped limit card；
In figure：Bifurcated 1, screwdriver rod 2, screw driver handle 3, gap 4, conducting wire 5.
Specific implementation mode
As shown in Figure 1, a kind of crane bar, including insulating bar 1, it is equipped with work head 2, including fixation on the top of insulating bar 1
Seat, the fixed seat are connect by connecting rod 3 with arc-shaped limit card 4, and fixed seat is used to fix on arc-shaped limit card 4 and insulating bar
1 top, the arc-shaped limit card 4 are located at the lower section of work head 2.
Preferably, as Figure 2-3, the fixed seat include two arc-shaped clips 5, the one of two arc-shaped clips 5
End is hinged by loose-leaf, and the other end is equipped with mounting hole, coordinates mounting hole to be fixed by bolt 6, the arc-shaped limit card 4 is logical
Connecting rod 3 is crossed to be fixedly connected with arc-shaped clip 5.
Preferably, the inside of the arc-shaped clip 5 is equipped with rubber pad 7.
Preferably, the opening of the arc-shaped limit card 4 extension rod 8 with outward extension.The extension rod being obliquely installed
Silk tool, which can be made to fall, to slide into arc-shaped limit card 4 along extension rod.
Preferably, the opening inner side of the arc-shaped limit card 4 is equipped with gag lever post 9, and gag lever post 9 is articulated on limit base 10,
Limit base 10 is fixed on the opening inner side of arc-shaped limit card 4, and the limit base 10 is equipped with and is rotated up for placing gag lever post 9
Limit stops 11, the lower section of the gag lever post 9 is equipped with the torque spring 12 for making gag lever post reset.
As illustrated in figures 4-5, fall silk tool when sliding to gag lever post 9, pressure is generated to gag lever post 9, it is made to be rotated down, is only needed
Crane bar, which is slightly tilted, which can make to fall silk tool, depresses gag lever post 9, falls into arc-shaped limit card 4, gag lever post after falling into
It is resetted under the action of torsional spring, making to fall silk tool will not skid off from arc-shaped limit card 4.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the technical solution that the scope of protection of the utility model should be recorded with claim include the technical solution of claim record
The equivalents of middle technical characteristic are protection domain.Equivalent replacement i.e. within this range is improved, also in the utility model
Protection domain within.
