In order to solve the above-mentioned technical problem, the utility model provides a kind of overhead power transmission line pole tower fall arrest protection dress
It sets, comprising:
Fall arrest track, has at least two through holes on the fall arrest track, and the through hole is to incline from top to bottom
Oblique angling hole；
Back-up protection block, the back-up protection block have at least two bolts, are inserted into the through hole respectively.
Wherein, the fall arrest track includes flat orbit portion and the cylinder for being symmetricly set on the orbit portion two sides
Shape guidance part, the through hole setting is in the orbit portion center.
Wherein, the through hole is two, is arranged side by side on the orbit portion by horizontal direction.
Wherein, the through hole is three, and isosceles triangle or triangular arranged are pressed on the orbit portion.
Wherein, the through hole is four, is arranged on the orbit portion by rectangular or square.
Wherein, the back-up protection block further includes supporting block, and described supporting block one end, the supporting block is arranged in the bolt
The other end be provided with lantern ring.
Wherein, the quantity of the bolt is identical as the quantity of the through hole, and corresponds.
The beneficial effect of the utility model embodiment is: effectively increasing the safety of high altitude operation；Structure is simple, makes
With efficient, without changing self-locking device overall structure, self-locking device mechanical structure is not destroyed；Through hole is only set on fall arrest track,
Transformation difficulty very little.

Specific embodiment
The explanation of following embodiment be with reference to attached drawing, can be to the particular implementation implemented to example the utility model
Example.The direction and position term that the utility model is previously mentioned, for example, "upper", "lower", "front", "rear", "left", "right", "inner", "
Outside ", " top ", " bottom ", " side " etc. are only direction or position with reference to attached drawing.Therefore, the direction used and position term
It is rather than the limitation to scope of protection of the utility model to illustrate and understand the utility model.
Referring to shown in Fig. 1-Fig. 4, the utility model embodiment provides a kind of overhead power transmission line pole tower fall arrest
Protective device, comprising:
Fall arrest track 1, has at least two through holes 10 on the fall arrest track 1, and the through hole 10 is from upper
Inclined angling hole under and；
Back-up protection block 2, the back-up protection block 2 have at least two bolts 20, are inserted into the through hole 10 respectively.
Specifically, fall arrest track 1 includes flat orbit portion 12 and the cylinder for being symmetricly set on 12 two sides of orbit portion
Shape guidance part 11, the setting of through hole 10 is in 12 center of orbit portion.Through hole 10 runs through entire track from 12 back side aperture of orbit portion
The thickness in portion 12 is opened on 12 front of orbit portion.10 opening direction of through hole is oblique from top to bottom, to prevent bolt 20 from existing
Deviate from after insertion from through hole 10.
10 quantity of through hole of the present embodiment be it is at least two, so as to bolt 20 insertion after can play stable branch
Support effect.For example, it when through hole 10 is two, is arranged side by side on orbit portion 12 by horizontal direction；Through hole 10 is
At three, isosceles triangle or triangular arranged are pressed on orbit portion 12；When through hole 10 is four, in orbit portion
It is arranged on 12 by rectangular or square.
Whole back-up protection block 2 is in rectangle, is process by an iron block, to guarantee when by self-locking device external impacts
Enough intensity is kept, self-locking device is prevented to continue to glide.Back-up protection block 2 specifically includes supporting block 21, setting supporting block 21 1
The through hole on fall arrest track 1 can be inserted in the bolt 20 at end and the lantern ring 22 that 21 other end of supporting block is arranged in, bolt 20
10, realize the function of back-up protection.The quantity of bolt 20 is identical as the quantity of through hole 10, and corresponds, and makes each bolt
One through hole of insertion can be corresponded to.The effect of lantern ring 22 is that available rope passes through lantern ring 22, and back-up protection block is securely tied up
It is scheduled at the through hole 10 of fall arrest track 1.
The application process of the utility model embodiment is as follows:
The fall protection equipment of the utility model embodiment is taken by operating personnel to be taken with oneself or ties up mounted defeated
On electric overhead transmission line shaft tower fall arrest track 1, during installing self-locking device or more tower, arrival is reserved with to be run through operating personnel
When the position in hole 10, self-locking device is first allowed to slip over the position of through hole 10, is inserted into take and takes or be fixed on fall arrest rail with oneself
The bolt 20 of back-up protection block 2 on road 1；It is lower to arrive the position inserted with back-up protection block 2 after operating personnel fulfils assignment task
When setting, bolt 20 is extracted, original position is put back to.
By above description it is found that the utility model embodiment bring beneficial effect is: effectively increasing high-altitude work
The safety of industry；Structure is simple, using efficient, without changing self-locking device overall structure, does not destroy self-locking device mechanical structure；It is anti-fall
It falls and through hole, transformation difficulty very little is only set on track.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
