Description
Technical field
The utility model is related to power equipment construction, the instrument of inspection and repair shop, specifically a kind of maintenance ladder it is anti-fall
Device.
Background technology
At present, power equipment provides many facilities for our life, it may appear that and many power failures need repairing,
This just needs staff to climb to pedal the various bodies of rod and carry out work high above the ground, and some workmens select ladder to be used as to bars such as electric poles
The climbing tool of the maintenance of body, generally ladder one end is fixed on utility poles in the prior art, prevented in work progress, ladder
Inclination damages, and people can use of seat belts when climbing ladder work high above the ground, and they, which have the disadvantage that, works as people
The ladder stand period of the day from 11 p.m. to 1 a.m, safety belt are simply trapped among on electric pole or ladder, and dropping safety belt when climbing moves up, after human body
Trying hard to keep of facing upward is held safety belt and not slid down, but work high above the ground has many unexpected accidents, once people overhaul
Or during climbing, accidentally from falling from high altitude, now safety belt loses support and also together thrown with workmen, to constructor
The life threat of member is very big, and the safety belt on so simple and crude cat ladder is not ensured when the workmen of work high above the ground is falling
Safety protection function.
Utility model content
To solve the above problems, the utility model provides a kind of anti-fall device of maintenance ladder, effectively prevent workmen from stepping on
Space-time, thrown from maintenance ladder and caused by personal injury.
The utility model is achieved through the following technical solutions：
A kind of anti-fall device of maintenance ladder, described maintenance ladder include two vertical supports, and described anti-fall device is set
Put in the longitudinal chute in side face, described anti-fall device includes transverse slider and vertical block, the end of transverse slider
Driving gear and driven gear are connected with by rotary shaft respectively on face, described driving gear is meshed with driven gear, institute
The vertical block stated is the T-type structure that is made up of horizontal segment and vertical section, vertical section and driven tooth in described vertical block
Wheel is connected, and described driving gear is connected by connect band with safety belt.
Preferably, it is provided with skid resistant course on described vertical block.
Preferably, the height of described vertical block is more than the width of longitudinal chute.
Preferably, described driving gear and the gear that driven gear is different radii.
Preferably, described driving gear is bigger than the radius of driven gear.
Preferably, described safety belt is Collapsible structure.
Preferably, described connect band is securable band.
The beneficial effects of the utility model are：
（1）Anti-fall device of the present utility model is arranged in the longitudinal chute in side face, including transverse slider is with erecting
To block, driving gear and driven gear are connected with by rotary shaft respectively on the end face of transverse slider, driving gear passes through company
Tape splicing links together with safety belt and workmen, when workmen normally climbs, is driven by transverse slider anti-
Fall device is climbed together, when workmen makes a misstep accidentally from maintenance ladder, passes through connect band by quick downward power
The rotation of driving gear is driven, so as to drive the rotation of driven gear, and vertical block is connected with driven gear, so as to drive
The rotation of vertical block, because the height of vertical block is more than the width of longitudinal chute so that vertical block tilt be stuck in it is vertical
Into chute, human body is set to stop tenesmus；
（2）Vertical block of the present utility model is the T-type structure being made up of horizontal segment and vertical section, perpendicular in vertical block
Straight section is connected with driven gear, the setting of T-type structure, increases the contact area of vertical block and longitudinal chute, stops human body
What is only dropped is more rapid, and is provided with skid resistant course on vertical block, increasing friction force, effectively prevents from continuing to drop；
（3）Described driving gear and the gear that driven gear is different radii, and the radius ratio driven tooth of driving gear
The radius of wheel is big, and tooth radius is big, and rotating speed is slow, and tooth radius is small, and rotating speed is fast, therefore such design, can be connected with
The driven tooth rotation of vertical block faster, so that vertical block is more rapidly stuck in longitudinal chute, prevents human body from continuing
Tenesmus.

Embodiment
With reference to specific embodiment, the utility model is described in further detail：
Embodiment 1
A kind of anti-fall device of maintenance ladder, maintenance ladder 1 include two vertical supports 2, and anti-fall device is arranged on the side of support 2
In longitudinal chute 3 on face, anti-fall device includes transverse slider 4 and vertical block 5, passes through respectively on the end face of transverse slider 4
Rotary shaft 6 is connected with driving gear 7 and driven gear 8, and driving gear 7 is meshed with driven gear 8, and driving gear 7 compares
The radius of driven gear 8 is big, and vertical block 5 is the T-type structure that is made up of horizontal segment and vertical section, vertical in vertical block 5
Section is connected with driven gear 8, skid resistant course is provided with vertical block 5, and the height of vertical block 5 is more than longitudinal chute 3
Width, driving gear 7 are connected by connect band 9 with safety belt 10, and safety belt 10 is Collapsible structure, and connect band 9 is securable
Band.When workmen makes a misstep, quick downward power drives the rotation of driving gear 7 by connect band 9, then drives driven
The rotation of gear 8, so as to drive the rotation of vertical block 5, vertical block 5 is tiltedly stuck in longitudinal chute 3, make under human body stopping
Pendant, the setting of T-type structure, increase the contact area of vertical block 5 and longitudinal chute 3, human body is stopped the more rapid of tenesmus,
And be provided with skid resistant course on vertical block 5, increasing friction force, effectively prevent from continuing to drop, and the radius ratio of driving gear 7 from
The radius of moving gear 8 is big, can be connected with 8 turns of the driven gear of vertical block 5 faster, so that vertical block 5 is more
