The generation of later period work holdup phenomenon, saves project amount, ensure that the safe operation of construction quality and railway.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of positioning device controlling mast foundation for overhead contact wire system position, including positioning plate, the positioning plate are equipped with and connect
The first positioning hole and second location hole of net-fault cast-in fixing bolt connection, the positioning plate are symmetrically fixed on Z-shaped by fixture nut
On the upper horizontal part of bracket, the Z-shaped bracket further includes vertical component effect and lower horizontal part, is between the upper horizontal part and vertical component effect
Right angle, between the lower horizontal part and vertical component effect at right angles.
The quantity of the Z-shaped bracket is two.
The lower horizontal part of the Z-shaped bracket is equipped with the keyhole connecting with contact net basic mould.
It is equipped with the first stiffener between the upper horizontal part and vertical component effect, the is equipped between the lower horizontal part and vertical component effect
Two stiffeners.
The positioning plate is hard plastic board, and the Z-shaped bracket is 3mm thick steel plate.
The quantity of the second location hole is 8, parallel and symmetrical to be arranged on positioning plate.
The first positioning hole size and second location hole size and box beam pre-embedded steel slab of the positioning plate reserve pore size one
It causes.
The beneficial effects of the utility model are: the utility model positioning plate by fixture nut be symmetrically fixed on it is several Z-shaped
On the upper horizontal part of bracket, and Z-shaped bracket is equipped with stiffener, has enough strength and stabilities, can be in contact net base
In plinth work progress, cast-in fixing bolt is fixed, so that cast-in fixing bolt is not generated positioning due to reinforcing bar deforms or constructs and vibrates, positioning accurate
Exactness is high, has prevented contact net encroachment line phenomenon.The utility model is easy to operate, is easily installed and removes, greatly alleviates labor
Fatigue resistance improves production efficiency.
