Abstract
The utility model relates to a transmission line is with folded cascade foot nail of preventing that non professional mistake is stepped on, its characterized in that: follow closely the body, utilize removable pin axle articulated splint to constitute with foot nail body by the foot, the splint other end is channel -section steel form and is equipped with and is used for the bolt hole I be connected with the transmission line shaft tower, the one end that foot nail body is close to the transmission line shaft tower is equipped with right angle shape stopper, when foot nail body is on a parallel with the horizontal plane at operating condition, the right angle avris and the laminating of transmission line shaft tower of right angle shape stopper, the position that splint correspond foot nail body is equipped with bolt hole II, hexagonal countersink bolt in being equipped with in the bolt hole II, the other end of foot nail body is crooked along its length direction syncline top. Simple structure, convenient to use make the foot nail set up and have more standardization and security.
Description
Technical field
This utility model relates to the foot nail on electric power line pole tower, and a kind of anti-layman used for transmission line steps on by mistake
Folding foot nail.
Background technology
The foot nail being installed on electric power line pole tower is that circuit is overhauled in work about electric power personnel climbing for convenience to head of mast, existing
Foot nail the most cylindrical, be parallel to horizontal plane, foot is followed closely one end and is joined with bolts with shaft tower profit.There are the following problems for it:
1, outside being mostly exposed to due to transmission line of electricity, child is in the case of unattended or other laymans are likely to follow closely along foot
Upwards climb, there is the potential safety hazard that falling from high altitude occurs；2, foot nail is constantly in and horizontal stretches state, easily to its of electric operating
His facility and staff cause interference.
Summary of the invention
The purpose of this utility model is to provide for a kind of simple in construction, easy to use used for transmission line anti-solving the problems referred to above
The folding foot nail that layman steps on by mistake, makes foot nail arrange more standardization and safety.
The technical solution of the utility model is:
The folding foot nail that a kind of anti-layman used for transmission line steps on by mistake, it is characterised in that: followed closely body and foot nail by foot
Body utilizes the clamping plate composition that active pin shaft is hinged, and the described clamping plate other end is channel-section steel shape and is provided with for electric power line pole tower even
The bolt hole I connect, described foot nail body is provided with square limited block near one end of electric power line pole tower, when foot nail body is parallel
When horizontal plane is in running order, the right angle avris of described square limited block is fitted with electric power line pole tower, described clamping plate pair
The position answering foot nail body is provided with bolt hole II, is provided with interior hexagonal dormant bolt in described bolt hole II, and described foot follows closely the another of body
One end bends the most obliquely upward.
The beneficial effects of the utility model are: 1, owing to clamping plate are connected fixing with electric power line pole tower, and foot nail body utilizes removable pin
Axle is hinged with clamping plate, so when operation completes, when not using foot to follow closely, foot can being followed closely body and overturns to the direction of electric power line pole tower,
And utilize the interior hexagonal dormant bolt needing specialty spanner just can screw to be locked, thus layman is prevented to pass through foot nail originally
Body climbs shaft tower, eliminates potential safety hazard；On the other hand, it also avoid foot nail other facilities of body interference and staff's work；
2, square limited block foot nail body be parallel to horizontal plane in running order time, play a supporting role, it is ensured that foot nail body
Stability, it is ensured that the safety of staff；3, foot nail arranges and more standardizes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (under duty)；
Fig. 2 is structural representation of the present utility model (under off working state)；
Fig. 3 is the top view of clamping plate of the present utility model.
In figure: 1. electric power line pole tower, 2. clamping plate, 3. foot nail body, 4. square limited block, 5. active pin shaft, 6. in six
Angle dormant bolt, 7. bolt hole I, 8. bolt hole II.
Detailed description of the invention
As it can be seen, the folding foot nail that this anti-layman used for transmission line steps on by mistake, foot nail body 3 and foot follow closely this
The clamping plate 2 that body 3 utilizes active pin shaft 5 hinged form, described clamping plate 2 other end be channel-section steel shape and be provided with for transmission line of electricity
The bolt hole I 7 that shaft tower 1 connects, described foot nail body 3 is provided with square limited block 4 near one end of electric power line pole tower 1,
When foot nail body 3 be parallel to horizontal plane in running order time, the right angle avris of described square limited block 4 and transmission line of electricity bar
Tower 1 is fitted, and the position of described clamping plate 2 corresponding foot nail body 3 is provided with bolt hole II 8, is provided with interior hexagonal in described bolt hole II 8
Dormant bolt 6, the other end of described foot nail body 3 bends the most obliquely upward.
