Technical field
The utility model relates to a kind of switch operation bar of effective protection electric power overhaul personnel personal safety, relates in particular to a kind of switch operation bar with the umbrella shape protection network.
Background technology
At present, in being engaged in line maintenance and accident treatment work, the disconnecting link present position is higher, the maintainer need put cleek by ladder or on pin and ascend a height and operate, owing to there is not fixture on one's body, do not carry any safety devices again, the maintenance personal has to be in the disconnecting link below and uses pull bar to operate, and particularly does the operation of separating brake and combined floodgate on vertical plane.Because disconnecting link is outmoded aging, the wearing and tearing of getting rusty, maintenance personal's health is restricted, firmly be difficult for unfavorable factors such as assurance, existing action bars does not have safeguard procedures again, and often overexerting causes part parts or disconnecting link integral body to come off, and brings great potential safety hazard to the maintainer.Therefore need a kind of operation pull bar that has protector, to protect maintenance personal's personal safety as much as possible.
Summary of the invention
The purpose of this utility model is to provide a kind of disconnecting link parts of can handling to fall at the too simple problem of bringing personal safety hidden danger easily to operating personnel of existing switch operation bar, effectively protects the switch operation bar of operating personnel's personal safety.
The technical solution adopted in the utility model is as follows:
The switch operation bar that this has the umbrella shape protection network comprises mobile jib sleeve, secondary bar, push-and-pull hook and umbrella shape protection network, and the secondary bar of described mobile jib sleeve internal fixation is installed the push-and-pull hook at secondary masthead end, the fixing inverted umbrella shape protection network on secondary bar top.
Described umbrella shape protection network comprises nest, following nest, long bone, short bone, spring and bullet, described short bone is tilting at last nest periphery, long bone is tilting at following nest periphery, the short bone diagonal brace is on long bone, following nest is fixed on the secondary bar, last nest and secondary bar are slidingly matched, and between last nest and the following nest spring are set, and bullet places on the secondary bar.
The described mobile jib lower cartridge outside is provided with the corresponding groove of arranging of five finger positions of the right hand palm according to the people.Five fingers embed wherein during operation, can play good skidproof effect.
Described mobile jib sleeve and secondary bar be for being slidingly matched, secondary bar can be in the mobile jib sleeve telescopic slide, cooperate fixed joint bar position by bolt set on the through hole of the set some equidistant arrangements in secondary bar bottom and the mobile jib sleeve.Visual execute-in-place actual needs is adjusted the position of secondary bar in the mobile jib sleeve, to regulate the length of action bars.
It is low, safe and reliable, easy to operate to the utlity model has manufacturing and maintenance cost, and highly versatile is easy to carry, the advantage that is easy to promote.In being engaged in the work of treatment of line maintenance and field accident, use the switch operation bar of band umbrella shape protection network can prevent from effectively to protect operating personnel's personal safety because of causing the disconnecting link parts potential safety hazard that comes off and bring in whole or in part accidentally to the maintainer.
Description of drawings
Accompanying drawing is the utility model overall structure schematic diagram.
Embodiment
Further introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to accompanying drawing, the utility model is mainly by mobile jib sleeve 1, secondary bar 2, compositions such as push-and-pull hook 3 and umbrella protection network 4.
The secondary bar 2 of the scalable slip of mobile jib sleeve 1 internal fixation, push-and-pull hook 3 is fixed on the secondary bar 2 top bolt heads 9 by its nut 10, and push-and-pull hook 3 contacts stressed with the disconnecting link parts, the action of the separating brake that closes a floodgate.
The fixing inverted umbrella shape protection network 4 on secondary bar 2 tops.Umbrella shape protection network 4 comprises nest 11, following nest 12, long bone 14, short bone 13, spring 15 and bullet 8.Ten six roots of sensation short bones 13 are tilting at last nest 11 peripheries, ten six roots of sensation long bones 14 are tilting at following nest 12 peripheries, short bone 13 diagonal braces are on long bone 14, following nest 12 is fixed on the secondary bar 2, last nest 11 is slidingly matched with secondary bar 2, can slide on secondary bar 2, between last nest 11 and the following nest 12 spring 15 is set, bullet 8 places on the secondary bar 2.
Push-and-pull hook 3, umbrella shape protection network 4 are metal material, and the outsourcing insulating material is made, and have both increased hardness, play insulation effect again.
The outside, mobile jib sleeve 1 bottom has the corresponding groove of arranging 5 of five finger positions of the right hand palm according to the people, and five fingers embed wherein during operation, play good skidproof effect.Mobile jib sleeve 1 internal diameter and secondary bar 2 external diameters are slidingly matched, and secondary bar 2 slides in mobile jib sleeve 1, the length of scalable whole operation bar.Fixed-use bolt 6 is arranged at mobile jib sleeve 1 top, and 12 through holes of equidistantly arranging 7 are arranged at secondary bar 2 bottoms, and the bolt 6 on the mobile jib sleeve 1 cooperates with through hole 7 on the secondary bar 2, but fixed joint bar 2.
Mobile jib sleeve 1 and secondary bar 2 are made by the insulating material bakelite, and bakelite has fabulous intensity and hardness, can play the good insulation performance effect again.
During use, the maintainer determines the length of suitable action bars according to the distance of present position and disconnecting link by regulating the position of secondary bar 2 in mobile jib sleeve 1, and uses bolt 6 to insert fixed joint bar 2 in the selected through hole 7.Nest 11 is to bullet 8 positions in the slip, spring 15 is extruded, the short bone 13 that is fixed on nest 11 peripheries drives long bone 14 struts umbrella shape protection network 4, the right hand the five fingers are held finger recess 5, or both hands lift mobile jib sleeve 1, sight line sees through umbrella shape protection network 4 mesh spaces to push-and-pull hook 3 firmly, carries out switch operation.
