Description
Technical field
The invention belongs to electric power specific purpose tool technical field, relate to a kind of right angle hanging ladder, especially a kind of multipurpose safety Work tool self-control " 3+1 " right angle hanging ladder.
Background technology
In power transmission lines overhauling operation, ladder is the managing security tools and instruments that utilization rate is very high.In the power transmission lines overhauling work of carrying out at present, the ladder class instrument using mainly contains following two kinds:
1, in power transmission lines overhauling operation, by cross-arm, enter the hanging ladder that wire is used.When operation, the crotch of one end hooks on wire, and the other end is tied to cross-arm, and operating personnel need not enter wire through insulator along ladder.This instrument can cause scar to wire, and operating personnel's center of gravity there will be and lean forward, and the activity duration is long, it is large to consume one's strength.
2, the cat ladder using in urban distribution network.Urban distribution network due to the steel tube towers that adopt more, and outlet operational difficulty in upkeep operation, utilizes cat ladder can conveniently approach power failure wire, carries out upkeep operation.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of multipurpose safety Work tool right angle hanging ladder is provided, it adopts two-piece design, adopts aluminum alloy materials to make, and detachable, lightweight, transportation is easy to carry.
The object of the invention is to solve by the following technical programs:
Plant multipurpose safety Work tool right angle hanging ladder, comprise the first aluminium alloy ladder section and the second aluminium alloy ladder section; Described the first aluminium alloy ladder section is connected by adjustable turning gear with the second aluminium alloy ladder section end; Described adjustable turning gear is provided with snap close; Described the first aluminium alloy ladder section outer end is provided with fixed hook; The outer end of described the second aluminium alloy ladder section is provided with and turns to hook.
The length of above-mentioned the first aluminium alloy ladder section is 3 meters; The length of described the second aluminium alloy ladder section is 1 meter.
Above-mentioned adjustable turning gear is by regulating snap close, movable gear and fixed gear three parts to form, and 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 realizes the engagement with fixed gear by spring, thereby one end of described adjusting snap close can drive the axle of movable gear to move up and down to be overcome spring pressure and make movable gear separated with fixed gear.
Above-mentioned movable gear is positioned at the second aluminium alloy ladder segment distance rotating shaft 6cm place.
The rotating shaft two ends of above-mentioned movable gear are arranged in the groove in the second aluminium alloy ladder section, and can be up and down in groove, in the second aluminium alloy ladder section, be also provided with a spring that withstands movable gear, the pressure-acting of spring makes movable gear and fixed gear engagement.
The present invention has following beneficial effect:
Multipurpose safety Work tool of the present invention right angle hanging ladder adopts two-part structure, is removablely divided into cat ladder and hanging ladder, and possesses it and use function, regulates snap close reliable and easy to operate, in practicality, can greatly save the activity duration, saves physical demands, improves fail safe.Employing aluminum alloy materials is made, and detachable, lightweight, transportation is easy to carry.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is left view and the connection bearing profile of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Wherein: 1 is fixed hook; 2 for turning to hook; 3 is adjustable turning gear; 4 for connecting pin; 5 for regulating snap close; 6 is the first aluminium alloy ladder section; 7 is the second aluminium alloy ladder section; 8 is movable gear; 9 is fixed gear; 10 is spring.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Referring to Fig. 1-Fig. 3, multipurpose safety Work tool of the present invention right angle hanging ladder, comprises the first aluminium alloy ladder section 6 and the second aluminium alloy ladder section 7; Described the first aluminium alloy ladder section 6 is connected by adjustable turning gear 3 with the second aluminium alloy ladder section 7 ends; Described adjustable turning gear 3 is provided with snap close; Described the first aluminium alloy ladder section 6 outer ends are provided with fixed hook 1; The outer end of described the second aluminium alloy ladder section 7 is provided with and turns to hook 2.
The length of described the first aluminium alloy ladder section 6 is 3 meters; The length of described the second aluminium alloy ladder section 7 is 1 meter.
Adjustable turning gear 3, by regulating snap close 5, movable gear 8 and fixed gear 9 three parts to form, is to connect the first aluminium alloy ladder section 6, the two-part device of the second aluminium alloy ladder section 7.
The first aluminium alloy ladder section 6, the second aluminium alloy ladder section 7 and fixed gear 9 are around same rotating shaft.And fixed gear 9 and the first aluminium alloy ladder section 6 are welded and fixed, and the two can not relatively rotate.Movable gear 8 is arranged in the second aluminium alloy ladder section 7, the rotating shaft two ends of movable gear 8 are arranged in the groove in the second aluminium alloy ladder section 7, and can be up and down in groove, in the second aluminium alloy ladder section 7, be also provided with a spring 10 that withstands movable gear 8, the pressure-acting of spring 10 makes movable gear 8 and fixed gear 9 engagements.Described adjusting snap close 5 is fixed in the second aluminium alloy ladder section 7 by the rotating shaft arranging in the middle, thereby regulating one end of snap close 5 can drive the axle of movable gear 8 to move up and down to overcome spring 10 pressure makes movable gear 8 separated with fixed gear 9; Regulating the other end of snap close 5 is driving handles.
In most preferred embodiment of the present invention, movable gear 8 is positioned at the second aluminium alloy ladder section 7 apart from rotating shaft 6cm place.
In the time of need to regulating hanging ladder bending angle, will regulate the upper end of snap close 5 to move, and regulate the lower end of snap close 5 will head on movable gear 8 exposed parts and make it separated with fixed gear 9, then carry out angular adjustment.Be adjusted to after suitable use angle, unclamp and regulate snap close 5, movable gear 8 by spring again with fixed gear 9 interlocks, thereby make hanging ladder be bent into certain angle, the work of being convenient to is used.
