Abstract
The utility model discloses a kind of nut splitter, comprise spiro cap, broken cutting knife and push rod; Described broken cutting knife longitudinal sliding motion is connected to spiro cap; Described push rod and broken cutting knife coaxially arrange and are threaded connection in spiro cap and broken cutting knife, and described push rod is provided with spline, and described spiro cap is provided with the worm screw of matching with described spline.Nut splitter of the present utility model, its each member fitting structure is stablized, and resistance to deformation intensity is high, not fragile, is beneficial to maintenance repair and the maintenance work of power system.
Description
Technical field
The utility model relates to a kind of nut detaching device, particularly relates to a kind of nut splitter.
Background technology
In the inner, external wire upkeep operation of power system, nut in the open in moist, high temperature or corrosive atmosphere, is easy to that corrosion occurs and kills for a long time.And once after nut corrosion kills, can make troubles to maintenance repair and upkeep operation, need to adopt specific purpose tool nut fragmentation to be removed, instrument at present for broken nut is provided with radially by the broken cutting knife of nut fragmentation usually, its broken cutting knife is promoted by push rod, but its broken cutting knife and push rod are all by mode transmission that end face contacts, make brokenly the end face of cutting knife and push rod stressed, when this force is higher, easily cause brokenly cutting knife and push rod end wear and distortion, cause push rod and extremely swollen between broken cutting knife and corresponding component, tool for destroying internal engagement structure, damage instrument, hinder maintenance repair and maintenance work.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of nut splitter, and its each member fitting structure is stablized, and resistance to deformation intensity is high, not fragile, is beneficial to maintenance repair and the maintenance work of power system.
Nut splitter of the present utility model, comprises spiro cap, broken cutting knife and push rod; Described broken cutting knife longitudinal sliding motion is connected to spiro cap; Described push rod and broken cutting knife coaxially arrange and are threaded connection in spiro cap and broken cutting knife, and described push rod is provided with spline, and described spiro cap is provided with the worm screw of matching with described spline.
Further, also comprise two back-up blocks and be rotationally connected with the screw rod of spiro cap through two back-up blocks single-degree-of-freedom; Two back-up blocks and broken cutting knife are along triangular arrangement in spiro cap, and two back-up blocks are laterally slidably connected to spiro cap; Screw rod and back-up block are laterally slided for driving two back-up blocks by threaded engagement.
Further, to be connected to the screw thread of spiro cap contrary with the thread rotary orientation that push rod is connected to brokenly cutting knife for described push rod.
Further, described screw rod is contrary with two parts thread rotary orientation that two back-up blocks match.
Further, described two back-up blocks and broken cutting knife three to distribute and with the line of two back-up blocks for base along isosceles triangle.
Further, be also fixed with outside described spiro cap and knock cone for what knock nut chip.
The beneficial effects of the utility model: nut splitter of the present utility model, its each member fitting structure is stablized, and resistance to deformation intensity is high, not fragile, is beneficial to maintenance repair and the maintenance work of power system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the nut splitter of the present embodiment, comprises spiro cap 1, broken cutting knife 2 and push rod 3; The longitudinal sliding motion of described broken cutting knife 2 is connected to spiro cap 1; Described push rod 3 arranges with broken cutting knife 2 is coaxial and is threaded connection in spiro cap 1 and broken cutting knife 2; Push rod 3 is provided with spline, described spiro cap 1 is provided with the worm screw 7 of matching with described spline, by rationally arranging the length that is threaded between push rod 3 with broken cutting knife 2, can make to produce larger contact area between push rod 3 and broken cutting knife 2, therefore avoid in use between push rod 3 and broken cutting knife 2 because of stressed excessive and cause malformation, not fragile, be beneficial to maintenance repair and the maintenance work of power system.
In the present embodiment, rotary worm 7, wants to coordinate with the spline of push rod 3 by worm screw 7, drives push rod 3 rotate and move up and down, thus drives broken cutting knife 2 to carry out work.
In the present embodiment, the screw thread that described push rod 3 is connected to spiro cap 1 is contrary with the thread rotary orientation that push rod 3 is connected to brokenly cutting knife 2, can ensure to drive broken cutting knife 2 effectively to slide by push rod 3.
In the present embodiment, also comprise two back-up blocks 4 and through two back-up blocks 4 and single-degree-of-freedom is rotationally connected with the screw rod 5 of spiro cap 1; Two back-up blocks 4 are with broken cutting knife 2 along triangular arrangement in spiro cap 1, and two back-up blocks 4 are laterally slidably connected to spiro cap 1; Screw rod 5 is laterally slided for driving two back-up blocks 4 by threaded engagement with back-up block 4, and screw rod 5 is Step Shaft structure, and the corresponding screw rod of spiro cap 15 is provided with removable end cap, and screw rod 5 can be dismantled and assemble; Utilize back-up block 4 can and the adjustable performance in lateral attitude can ensure to locate reliably the nut of different size, after repeatedly using simultaneously, easily cause back-up block 4 compressive deformation, can change back-up block 4, save maintenance cost.
In the present embodiment, described two back-up blocks 4 and broken cutting knife 2 three to distribute and with the line of two back-up blocks 4 for base along isosceles triangle.
In the present embodiment, described screw rod 5 is contrary with two parts thread rotary orientation that two back-up blocks 4 match, and two back-up block 4 symmetries therefore can be driven during rotating screw bolt 5 to slide.
In the present embodiment, be also fixed with outside described spiro cap 1 and knock cone 6 for what knock nut chip, utilize broken cutting knife 2 to knock cone 6 knocked out using after nut fragmentation by nut disintegrating slag.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
