Abstract
The utility model discloses the replaceable special pin pulling clamp of a kind of insulator R type pin, comprise write off bar and write off head, described write off bar comprises handle, support bar and back-up block, described support bar one end is connected with handle, the other end is connected with back-up block, described support bar has a female connecting hole of band, described connecting hole is vertical with handle orientations near back-up block, and described write off head is made up of crotch and screw rod, and be connected on support bar by screw rod and connecting hole.Pioneering R type of extracting pin puller, can change different write off heads according to the size difference of R type pin, make extracting of R type pin more time saving and energy saving, improve operating efficiency; Ingenious utilization mechanics principle, novel in design, easy to use, good reliability, applied widelyly can be used for 110--220 KV transmission line.
Description
Technical field
The utility model relates to electric power overhaul field of tool, particularly the replaceable special pin pulling clamp of a kind of insulator R type pin.
Background technology
Novel R type pin is generally adopted in current high voltage composite insulators cross-arm side bowl head; but often there will be insulator due to outside destroy or other reasons in transmission line running there is damaged phenomenon; must change in time for underproof insulator; change insulator just the R type pin in insulator cross-arm side bowl head to be extracted; but this R type pin has advantage that is not yielding, stable performance, so not easily take out after installing.
In use because its application scenario this R type pin different is also of different sizes size, we are changing the general method adopting hand vice or use common pliers to extract R type pin in insulator work, this method extremely bothers, waste time and energy, and more difficult for extracting of some larger or less R type pins, serious affects operating efficiency.
Utility model content
Technical problem to be solved in the utility model there is provided the replaceable special pin pulling clamp of a kind of insulator R type pin, the utility model can change different write off heads according to the size difference of R type pin, easy to use, and utilize mechanics principle, R type pin can be extracted efficiently, save the activity duration.
The technical solution adopted in the utility model is:
The replaceable special pin pulling clamp of a kind of insulator R type pin, comprise write off bar and write off head, described write off bar comprises handle, support bar and back-up block, described support bar one end is connected with handle, the other end is connected with back-up block, described support bar has a female connecting hole of band, described connecting hole is vertical with handle orientations near back-up block, and described write off head is made up of crotch and screw rod, and be connected on support bar by screw rod and connecting hole.
Crotch on described write off head is of different sizes, and can change different write off heads according to the size of different R type pin.
Described back-up block is provided with slipmat, and during for preventing positioning supports, back-up block skids.
The crotch of described write off head is provided with hangnail, and when can effectively prevent from extracting R type pin, write off head skids.
R type of the extracting pin puller that the utility model is pioneering, can change different write off heads according to the size of R type pin, make extracting of R type pin more time saving and energy saving, improve operating efficiency; Ingenious utilization mechanics principle, novel in design, easy to use, good reliability, applied widelyly can be used for 110--220 KV transmission line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of the utility model write off bar.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail.
The replaceable special pin pulling clamp of a kind of insulator R type pin, as shown in Figure 1, comprise write off bar and write off head, described write off bar comprises handle, support bar and back-up block, wherein support bar one end is connected with handle, the other end is connected with back-up block, and on support bar, have a female connecting hole 4 of band, this connecting hole is vertical with handle orientations near back-up block, back-up block front end is provided with slipmat 7, described write off head is made up of crotch 5 and screw rod 6, its crotch is provided with hangnail 8, and write off head is connected on support bar by screw rod and connecting hole.
In actual applications, vary in size so they are also different for fixing R type pin size due to insulator, in machinery industry standard, the model of R type pin and size are also specified, the utility model is exactly the crotch designing different size according to different R type pins, according to the write off head that the size Selection of R type pin is suitable during use, be connected on support bar by screw rod and connecting hole.Hand-held handle, penetrates in the pin-and-hole of R type pin by the crotch of write off head, by back-up block positioning support support point, the lever principle of mechanics just can be utilized to extract R type pin efficiently.
