Abstract

An electric line first aid repair pole-tower foundation served as the foundation for the temporary pole-tower in the electric power system circuit first aid repair work is provided. The pole-tower foundation has a pedestal to connect the pole-tower, wherein the pedestal comprises a pedestal plate and a cardinal axis support plate welded on the pedestal plate; wherein the support plate is connected to a cardinal axis which is connected to the bottom of the pole-tower, and a through hole is vertically positioned on the cardinal axis which is used to perforate through and lock on the pole-tower bottom inserted at two sides of the cardinal axis and the pin connected with the cardinal axis; the utility model is characterized in that: a splicing pedestal plate is firmly fixed under the pedestal plate to enlarge the supporting area; the pedestal is welded with an opening connecting ring which can connect the pedestals of two symmetrical pole-towers with a steel rope to prevent the door type pole-tower bottom from moving outside. According to the geological condition of the installation environment, the utility model can adopt the slicing pedestal plates of different forms and various sizes connected under the pedestal to increase the supporting area of the pedestal base, and have the advantages of light weight, convenient installation, easy assembly and strong bearing capacity.

Description

Power circuit repairing pole and tower foundation

Technical field

The utility model relates to the basic technology field, especially relates to the basic technology field of the interim shaft tower in the circuit on power system repairing.

Background technology

In power system, the accident of falling the shaft tower of overhead transmission line happens occasionally, and causes power failure, and repairing fast restored electricity in the short as far as possible time.And the shaft tower in the transmission line of electricity is generally all higher, lift repairing, and highly equal or higher interim shaft tower need be arranged, the shaft tower that also has the temporary transient replacement of the interim shaft tower of direct usefulness to be fallen.In a short period of time higher interim shaft tower is installed, its basis is crucial, and it is different to fall shaft tower environment of living in, landform, exhales height, span, wind speed, icing and geological condition etc. also to have nothing in common with each other, for installation has brought difficulty.The method that adopts is that for the hard ground, the base that directly will connect shaft tower is fixed in ground with drill rod at present; For resembling soft foundations such as rice terrace, sandy soil ground, then in that to connect under the base of shaft tower lining wood etc. fixing again.This way of temporarily piecing together, the reason condition restriction, often insecure, leave accident potential.

Summary of the invention

The purpose of this utility model is for overcoming the deficiency of prior art, provide a kind of easy to assembly, can be according to the geological condition of erecting bed, select the power circuit repairing pole and tower foundation of different big or small assembly unit bases, easy construction when making the shaft tower repairing, install firmly, the accident of stopping takes place.

For achieving the above object, the new technical scheme of this practicality is such: a kind of power circuit repairing pole and tower foundation, the base that one connection shaft tower is arranged, base comprises bed plate and the hinge base plate that welds thereon, be hinged with the hinge of coupling bar tower bottom on the base plate, one through hole perpendicular to the axle center is arranged on this hinge, be used for passing and locking shaft tower bottom and the joining pin of hinge that inserts the hinge both sides; It is characterized in that being fixedly connected under base increases the splicing bed plate of bearing surface, with the bearing area on enlarged base basis; Also be welded with root on the said base and open connecting ring, two shaft tower bases of symmetry can be connected with wire rope, outside both sides, move to prevent gate-type shaft tower bottom.

Owing to adopted technique scheme, the utility model can adopt multi-form in the base lower link and splicing bed plate different sizes according to the geological conditions of installation environment, to strengthen the bearing area of footing foundation, have in light weight, easy for installation, assembly unit is easy, the characteristics that supporting capacity is strong.

The specific embodiment

Embodiment 1:

By Fig. 1--shown in Figure 2, a kind of power circuit repairing pole and tower foundation of the present utility model, the base that one connection shaft tower is arranged, base comprises bed plate 6 and the hinge base plate 1 that welds thereon, be hinged with the hinge 2 of coupling bar tower bottom on the base plate, one through hole 3 perpendicular to the axle center is arranged on this hinge, be used for passing and locking shaft tower bottom and the joining pin of hinge that inserts the hinge both sides; It is characterized in that being fixedly connected under base increases the splicing bed plate 7 of bearing surface, and its cross sectional shape is two square frame shapes, hollow, and the two ends open-work can insert the lumps of wood, in case sink in the basis; Also be welded with root on the said base and open connecting ring 5, two shaft tower bases of symmetry can be connected with wire rope, outside both sides, move to prevent gate-type shaft tower bottom; For improving intensity, between bed plate 6 and hinge base plate 1, be fixed with stiffener 4.

Embodiment 2:

Splicing bed plate 7 among the embodiment 1 is made into by polylith trough slab splicing, and Open Side Down, on have the horizontal stripe 8 of connection fixing with it, on trough slab, have and can insert the through hole 9 that drill rod and ground are fixed; All the other repeat embodiment 1.

Embodiment 3:

Make the splicing bed plate 7 among the embodiment 1 into disc, be welded with reinforcing rib 10 between itself and base, the nearly disk periphery of splicing bed plate is along being evenly equipped with assembly unit bolt hole 11, the plate of assembly unit enlarged base again 12; Said enlarged base plate 12 is 120 ° sector shape, which is provided with and assembly unit bolt hole 11 corresponding assembly unit bolts hole 13, will splice bed plate 7 with bolt and fix with enlarged base plate 12, also is provided with thereon to insert the fixing through hole 14 of drill rod and ground; All the other repeat embodiment 1.
