Description
Technical field
The present invention relates to the technical fields of climbing tool, more particularly, to a kind of ladder.
Background technique
Such as the Chinese invention patent that notification number is CN107055318B, attached drawing 5 is pointed out in the middle, traditional portal-framed structure packet
It includes in the girder being laterally arranged, there are two supporting legs, the length of two supporting legs to keep for setting straight down respectively at the both ends of the girder
Relatively uniform, lower end and the ground of two supporting legs offset, and in actual use, a lifting machine can be arranged on girder, lifting
Machine can carry out left and right sliding along girder.
One ladder can be also set on common door frame side, and ladder structure generally includes a terraced body, the length direction of terraced body
It is consistent with the length direction of supporting leg, safety guide rail can be arranged in the outside of terraced body, if lifting machine occurs in use
When failure, maintenance personal is climbed on terraced body, and when there is the trend toppled over, safety guide rail can give maintenance personal's support
Point improves safety.
But since the height of door frame is higher, safety guide rail includes multiple support rings, and multiple support rings are along terraced body
Length direction is arranged, and there are biggish spacing between adjacent supports ring, but are provided so as to mode, when operator is real
When toppling over, operator is easy to fall from clearance space out, and security performance reduces；Safety is promoted, is door frame at this stage
One of an important factor for ladder design will consider.
Summary of the invention
The object of the present invention is to provide a kind of ladders, can promote safety when climbing.
Foregoing invention purpose of the invention has the technical scheme that a kind of ladder, including in vertical
The terraced body of setting, several support groups, several support groups are arranged along the length direction of terraced body, and each support group includes at least
One triggering ring, a protective ring, triggering ring are located at the top of protective ring；
The upper ring surface of the triggering ring is equipped with pressing mechanism；
The inner ring surface of the protective ring is equipped with annular groove, and the protective ring is equipped with protection mechanism, the protection mechanism packet
It includes fixed block, sliding block group, be attracted block, the sliding block group is located at fixed block and is attracted between block, and the fixed block is fixed on protection
The inner ring surface of ring, the sliding block group include at least one piece of slipping block, and the slipping block sliding is connected to annular groove, the actuation
Block sliding is connected to annular groove, and the fixed block, sliding block group are attracted between block three and are connected by elastic spring；
Fixed block, sliding block group, actuation block are connected with buffer zone between any two；
It is connected between the pressing mechanism and protection mechanism by trigger mechanism, the trigger mechanism is used for fixed block, sliding block
Group, actuation block three are limited to elastic spring and are compressed to most short position；
The pressing force of climbing person is transferred to pressing mechanism, and pressing mechanism is released to fixed block by trigger mechanism, sliding block group, is attracted
The limit of block three, elastic spring push both sliding block group, actuation block to be slid in annular groove simultaneously.
By using above-mentioned technical proposal, under normal operating condition, fixed block, is attracted between block three sliding block group
Elastic spring compresses in length is located at fixed block, sliding block group, is attracted block three to position-limiting action that is most short, and being toggled mechanism
Between buffer zone will not influence climbing person and pass through triggering ring and protective ring；
When the trend fallen occurs in climbing person, climbing person's hand presses pressing mechanism, and pressing mechanism is by trigger mechanism, in turn
It releases to fixed block, sliding block group, the position-limiting action for being attracted block three, elastic spring can drive both sliding block group, actuation block along ring
Shape sliding slot is slid, at this point, fixed block, sliding block group, being attracted that block is substantially uniform is distributed on the circumferential position of protective ring, is connected
It in fixed block, sliding block group, is attracted block buffer zone between any two and can then be barred from inside protective ring, to limit under climbing person continues
It falls, and then improves the overall security of ladder.
Preferably, the pressing mechanism includes above triggering ring by pressure ring, described by between pressure ring and triggering ring
It is connected with by pressing spring, by between pressure ring and triggering ring, there are pressing gaps.
By using above-mentioned technical proposal, in normal operating condition, by the elastic force of pressing spring can will be jacked up by pressure ring in
Ring is triggered, make by pressure ring and is triggered between ring there are pressing gap, is pressed with facilitating by pressure ring.
Preferably, the trigger mechanism includes frizzen, and the upper end of the frizzen is contacted at by pressure ring, the triggering
The lower end of bar through be located at triggering ring below protective ring, the frizzen can stop be attracted block and limit sliding block group,
It is attracted block to slide, the frizzen is equipped with notch；
When moving downward by pressure ring driving fender rod, notch can accommodate sliding block group, actuation block passes through.
By using above-mentioned technical proposal, in normal state, frizzen can stop to be attracted block and limit sliding block group, be attracted
Block slides；When moving downward by pressure ring driving fender rod, notch can accommodate sliding block group, actuation block passes through, fixed block, cunning
Block group is attracted that block is substantially uniform is distributed on the circumferential position of protective ring, be connected to fixed block, sliding block group, be attracted block two-by-two it
Between buffer zone can then be barred from inside protective ring, continue to fall to limit climbing person, the triggering sensitivity of mechanism is higher, use
Stability it is also higher.
Preferably, the fixed block, be attracted in block and be equipped with magnet, fixed block and when being attracted block and being affixed can mutual magnetic force
Attract.
Block meeting is attracted after elastic spring drives sliding block group, actuation block is slid by using above-mentioned technical proposal
It offsets with fixed block, the magnet inside the two can occur mutually to be attracted at this time, to promote fixed block, sliding block group, be attracted block three
Configuration stability.
It preferably, further include several reinforcing rods, several reinforcing rods circumferentially array distribution centered on protective ring ring heart adds
Strong bar is connected on triggering ring outer ring surface and on protective ring outer ring surface.
By using above-mentioned technical proposal, reinforcing rod can effectively be reinforced, the overall structural strength of protective ring.
Preferably, buffer zone is equipped with adsorption piece, and the adsorption piece can be adsorbed on the inner ring surface of protective ring.
By using above-mentioned technical proposal, when fixed block, sliding block group, actuation block are toggled the limit of bar, adsorption piece
It can be adsorbed on the inner ring surface of protective ring, to be further reduced influence of the buffer zone to protective ring inner annular space.
