The crotch of Shi Yiduan hooks on wire, and the other end is tied to cross-arm, and operating personnel need not be through along ladder
Cross insulator and enter wire.Wire can be caused scar, and operating personnel's center of gravity meeting by this instrument
Appearance is leaned forward, activity duration length, consume one's strength big.
2, the cat ladder used in urban distribution network.Urban distribution network owing to using steel tube tower more,
In upkeep operation, outlet operation difficulty, utilizes cat ladder can facilitate close to power failure wire, examines
Repair operation.
Summary of the invention
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of multipurpose
Managing security tools and instruments right angle hanging ladder, it uses two-piece design, uses aluminum alloy materials to make, can
Split, lightweight, it is simple to carry transport.
It is an object of the invention to solve by the following technical programs:
Multipurpose safety Work tool right angle hanging ladder, including the first aluminium alloy ladder section and the second aluminum
Alloy cat ladder section；Described first aluminium alloy ladder section and the second aluminium alloy ladder section end are passed through can
Regulation turning gear connects；Described scalable turning gear is provided with snap close；Described first aluminum closes
Gold cat ladder section outer end is provided with fixed hook；The outer end of described second aluminium alloy ladder section is provided with
Turn to hook.
A length of 3 meters of above-mentioned first aluminium alloy ladder section；Described second aluminium alloy ladder section
A length of 1 meter.
Above-mentioned scalable turning gear is by regulating snap close, movable gear and fixed gear three
Being grouped into, the first aluminium alloy ladder section, the second aluminium alloy ladder section and fixed gear are around same
Rotating shaft；And fixed gear and the first aluminium alloy ladder section are welded and fixed；Movable gear is arranged
In the second aluminium alloy ladder section, and realized and the engaging of fixed gear by spring, described tune
One end of joint snap close can drive the axle of movable gear to move up and down thus overcome spring pressure
Movable gear is made to separate with fixed gear.
Above-mentioned movable gear is positioned at the second aluminium alloy ladder segment distance rotating shaft 6cm.
The rotating shaft two ends of above-mentioned movable gear are arranged on the groove in the second aluminium alloy ladder section
In, and can be up and down in groove, the second aluminium alloy ladder section is additionally provided with a top
Living the spring of movable gear, the pressure effect of spring makes movable gear nibble with fixed gear
Close.
The method have the advantages that
The multipurpose safety Work tool right angle hanging ladder of the present invention uses two-part structure, detachable
For cat ladder and hanging ladder, and possessing it and use function, regulation snap close is reliable and easy to operate, real
The activity duration can be greatly saved in, save physical demands, improve safety.Use aluminium alloy
Material makes, detachable, lightweight, it is simple to carry transport.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention；
Fig. 2 is the left view of Fig. 1 and connects bearing profile；
Fig. 3 is the top view of Fig. 1.
Wherein: 1 is fixed hook；2 for turning to hook；3 is scalable turning gear；4
For connecting pin；5 is regulation snap close；6 is the first aluminium alloy ladder section；7 is that the second aluminum closes
Gold cat ladder section；8 is movable gear；9 is fixed gear；10 is spring.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail:
Seeing Fig. 1-Fig. 3, the multipurpose safety Work tool right angle hanging ladder of the present invention, including first
Aluminium alloy ladder section 6 and the second aluminium alloy ladder section 7；Described first aluminium alloy ladder section 6 He
Second aluminium alloy ladder section 7 end is connected by scalable turning gear 3；Described scalable turns
Shaft device 3 is provided with snap close；Described first aluminium alloy ladder section 6 outer end is provided with fixed hook
1；The outer end of described second aluminium alloy ladder section 7 is provided with and turns to hook 2.
A length of 3 meters of described first aluminium alloy ladder section 6；Described second aluminium alloy ladder
A length of 1 meter of section 7.
Scalable turning gear 3 is by regulation snap close 5, movable gear 8 and fixed gear 9 three
Part composition, is to connect first aluminium alloy ladder section the 6, second aluminium alloy ladder section 7 two parts
Device.
First aluminium alloy ladder section the 6, second aluminium alloy ladder section 7 and fixed gear 9 are around same
One rotating shaft.And fixed gear 9 is welded and fixed with the first aluminium alloy ladder section 6, and the two can not
Relatively rotate.Movable gear 8 is arranged in the second aluminium alloy ladder section 7, movable gear
The rotating shaft two ends of 8 are arranged in the groove in the second aluminium alloy ladder section 7, it is possible in groove
Lower activity, is additionally provided with one in the second aluminium alloy ladder section 7 and withstands movable gear 8
Spring 10, the pressure effect of spring 10 makes movable gear 8 engage with fixed gear 9.Institute
State regulation snap close 5 and be fixed on the second aluminium alloy ladder section 7 by being disposed therein the rotating shaft in portion
On, one end of regulation snap close 5 can drive the axle of movable gear 8 to move up and down thus overcome
Spring 10 pressure makes movable gear 8 separate with fixed gear 9；Regulation snap close 5 another
End is driving handle.
