Description
Technical field
The present invention relates to specific purpose tool field, more particularly to a kind of Novel herringbone ladder.
Background technology
In agricultural planting at home, being planted in agricultural for fruit tree occupies an important position, generally known to us
The fruit such as apple, pears, peach, plum, persimmon, are all to have not a particle of flaw in everybody impression, very completely, but actual
On substantial amounts of substandard products fruit can be produced during harvesting because the harvesting of fruit is a very arduous job, i.e., to protect
The quality of fruit is demonstrate,proved, the efficiency of work is improved again；It is exactly the fruit for plucking eminence to be plucked in orchard most difficult, and hand is enough not
Arrive, eminence can only be climbed to ladder and goes to pluck, but ladder is leaned on common single ladder is bad, i.e., it is dangerous and difficult；Use common double ladder
The drawbacks of security is improved, but presence is very big in use:
1st, because the tree crown of fruit tree is very dense, common list ladder can not be close, and the both sides of common double ladder are all too wide, in tree crown
Middle support foot of ladder is extremely difficult.
2nd, common double ladder is formed by connecting by two single ladders, so having four foot of ladders, so total when putting double ladder
It is to have a pin hanging, very big work hidden danger is brought to staff, larger danger is caused.
3rd, the top of common double ladder is without that can climb the place helped, and when personnel work on top, two hands can not
Ladder is caught, the easy disequilibrium of body is dangerous.
Past, harvesting personnel can only carry out harvesting work using common single terraced and common double ladder
Industry, use is very inconvenient, while causing the low of the efficiency of work, ladder base is insecure, easily goes out during use
It is now unexpected, cause personnel to slide, personnel damage to harvesting.Therefore, it is badly in need of a kind of new instrument, can places and firmly may be used
Lean on, and can be easy to use, improve the efficiency of harvesting.
The content of the invention
The present invention proposes a kind of Novel herringbone ladder, and it can realize quick movement, and security reliability is high, makes operating personnel
The carry out harvesting operation more felt at ease, while improving the efficiency of harvesting, it is to avoid harvesting is that occur unexpected and improve safety
Property.
The purpose of the present invention can adopt the following technical scheme that to realize：
A kind of Novel herringbone ladder, it is made up of main ladder, secondary ladder, latch segment, fixed handle, pull rope, hand rod, described main ladder top
Beam and the secondary back timber of secondary ladder are by gemel connection, and latch segment and fixed handle are arranged on the side of the secondary back timber of secondary ladder, and hand rod is arranged on
In rotating shaft between latch segment and fixed handle, pull rope is arranged between main terraced middle beam and secondary terraced column；Described main ladder
It is made up of column, crossbeam and back timber, crossbeam is arranged between two root posts, back timber is arranged on the top of column；Described pair ladder
It is made up of secondary column, bearing diagonal beam and secondary back timber, secondary column is made up of a root post, bearing diagonal beam forming V-shape structure, is arranged on pair
The top of column, secondary crossbeam is arranged on the top of bearing diagonal beam；Locking pin and spring, latch segment are provided with described latch segment
Side, which is provided with three through holes, the through hole at middle part, is provided with rotating shaft, and locking pin divides into U-shaped structure, two cylinders of locking pin
In the through hole for the upper and lower part not being arranged on latch segment, spring is provided with locking pin.
Described hand rod is door frame-shaped construction, is made up of the montant and middle cross bar of both sides, the montant bottom of both sides
It is arranged with two through holes in parallel, upper through-hole is to be provided with locking pin locked on rotating shaft, latch segment in locking hole, lower through-hole to exist
In the through hole on top, hand rod both sides montant upper outside is provided with hook.
It is provided with the middle part of the described secondary column of pair ladder in capstan winch, capstan winch and is provided with handle, capstan winch on winding pull rope, capstan winch
There is auto-lock function.
Described pull rope one end is fixed on the crossbeam in the middle part of main ladder, and the other end is connected to capstan winch on the secondary column of secondary ladder
On.
Described fixed handle is square block, and middle part is provided with through hole, through hole and is provided with rotating shaft.
By the implementation of the present invention, good using effect has been reached：Novel herringbone ladder is while security is improved, energy
Enough easily close to the tree crown of fruit tree, two main two terraced one terraced with pair that keep a foothold keep a foothold to form three strong points, place
Stable, hand rod takes harvesting human hand, increases the stabilization of personnel, and can fast, accurately complete Novel herring bone
The carrying of ladder, the accident that the pull rope of adjustable-length avoids Novel herringbone ladder is separated, it is ensured that the safety of user of service.
