Use cat ladder.
The cat ladder of prior art includes single or double joint montant, and montant is provided with handrail, described montant be arranged above with hang
Hook, hangs over hook on cross-arm, workman's climbing operation up.The end face of hook is cambered surface, and the end face of cross-arm is plane, so
Hanging on cross-arm the most unstable, especially during climbing, cat ladder swings back and forth, and once amplitude of fluctuation is excessive, hook
It is easy for coming off in cross-arm, extremely dangerous.
Summary of the invention
The technical problem that mounting is insecure, easily swings back and forth, easily break off relations, this practicality is there is in order to solve prior art
Novel offer one steel tower cat ladder, to solve the deficiencies in the prior art.
To achieve these goals, this utility model is achieved through the following technical solutions:
A kind of steel tower cat ladder, sets armed montant including both sides, and the catching groove of the above and mounting cross-arm of described montant is even
Connect；The opening of described catching groove is vertically downward；It is characterized by the radical length of described catching groove mounting cross-arm more than montant；Described catching groove
The top of inner side is plane.
As improving further, described montant is provided with otic placode；Described otic placode is provided with the gear connected by axis of rotation
Pin；Described backing pin is provided with the alligator clamp being connected with otic placode elasticity；Being arranged below one and be arranged oppositely with backing pin of described catching groove
Extension rod.
As improving further, described backing pin is provided with the bracing wire hole of fixing bracing wire, and corresponding montant is provided with through wires hole；
One end of described bracing wire is fixed in bracing wire, and the other end is drawn from the bottom of montant by through wires hole.
As improving further, the bottom of described extension rod is bandy arc.
As improving further, for the arc being gradually curved to montant side below described otic placode.
As improving further, described handrail position on montant is relative to cross-arm vertical distribution.
This utility model changes the hook of prior art into groove, and has added backing pin, efficiently solves prior art
There is the technical problem that mounting is insecure, easily swings back and forth, easily break off relations.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the right view of Fig. 1.
In figure: 1, catching groove 2, perforation 3, montant 4, bracing wire 5, alligator clamp 6, rotating shaft 7, otic placode 8, handrail 9, prolongation
Bar 10, bracing wire hole 11, backing pin 12, cross-arm.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the technical solution of the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
In description of the present utility model, " " center ", " on ", D score, "left", "right", " perpendicular it should be noted that term
Directly ", " level ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, be only
Must have specific for the ease of describing this utility model and simplification description rather than instruction or the device of hint indication or element
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " the
One ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that instruction or hint relative importance.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", should be interpreted broadly " being connected ", " connection ", for example, it may be fix connection, it is also possible to be to removably connect, or integratedly
Connect；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Language concrete meaning in this utility model.
Embodiment 1:
According to Fig. 1 and Fig. 2, a kind of steel tower cat ladder, be provided with the montant 3 of handrail 8 including both sides, described montant 3 above with
The catching groove 1 of mounting cross-arm 12 connects；The opening of described catching groove 1 is vertically downward；It is characterized by described catching groove 1 and mounts the radial direction of cross-arm
Length is more than montant 3；Top inside described catching groove is plane.
Described montant 3 is provided with otic placode 7；Described otic placode is provided with the backing pin 11 being rotationally connected by rotating shaft 6；Described backing pin
It is provided with the alligator clamp 5 being connected with otic placode elasticity；Described catching groove the extension rod 9 that with backing pin be arranged oppositely is arranged below.
Described backing pin 11 is provided with the bracing wire hole 10 of fixing bracing wire 4, and corresponding montant 3 is provided with through wires hole 2；Described bracing wire
One end be fixed in bracing wire, the other end by through wires hole from the bottom of montant draw.
The bottom of described extension rod 9 is bandy arc.
For the arc being gradually curved to montant side below described otic placode 7.
The described handrail 8 position on montant is relative to cross-arm vertical distribution.
When steel tower overhauls, being directly buckled on steel tower cross-arm by the catching groove of this cat ladder, backing pin, under the pushing of cross-arm, rotates
Axle rotates, and after cross-arm arrives catching groove, backing pin is return under the effect of alligator clamp；When taking off, backing pin is pulled to rotate by bracing wire, so
After cat ladder is taken off from cross-arm.
The inner top surface of catching groove is plane, fits with cross-arm, so the rotation that will not be distorted；During climbing, montant
The pendulum force direction being subject to is the radial direction of cross-arm, and catching groove length is longer, so montant is resting state, and safe ready.
This utility model changes the hook of prior art into groove, and has added backing pin, efficiently solves prior art
There is the technical problem that mounting is insecure, easily swings back and forth, easily break off relations.
