Abstract
A spanning support for traction cables belongs to the field of electric stringing equipment. The spanning support comprises a spanning beam, and the spanning support is characterized in that the spanning beam is in an arc shape, a middle part of the spanning beam is provided with a main support, and two ends of the spanning beam are respectively provided with connectors used for connecting a steel strand. In use, the main support is fixed on a cross-arm and is used for supporting the spanning beam, the connectors on two ends of the spanning beam connect the spanning beam with the steel strand, so two ends of the spanning beam are tightly attached with the steel strand, and cable hooks can conveniently slide to the spanning beam from the steel strand and can smoothly pass through the cross-arm. In many years, aerial cables are fixed by men on a pulley, and the men and the pulley cannot directly pass though when steel strand support points are fixed on spanning electric poles; and the spanning support for the traction cables is cooperated with novel hooks to solve the above problem. Erection and fixation of aerial cables are realized in continuous span distances, and simultaneously the electric poles and the cross-arm fixing steel strand support points are smoothly crossed. Conveniences are brought to field construction, work efficiency is improved, and high-altitude falling accident rate is reduced.
Description
Technical field
The utility model belongs to the electric stringing apparatus field, and especially a kind of trailing cable is crossed over support.
Background technology
In line with international standards and the times of present power supply enterprise, power load is doubled and redoubled, and protects district trees and overhead transmission line contradiction.Safety supplies the especially eternal theme of power supply enterprise of electricity consumption, and electrical network upgrading aerial cable line insulating is imperative, and its quantities mainly is: set up steel strand wire, hang built on stilts attached cable.
Tradition aerial cable erection mode generally has two kinds: after setting up steel strand wire, the one, the staff sits the dedicated pulley high-altitude and hangs attached cable with old-fashioned cable clip, and can only span segmentation of a span carry out, whenever finishing a span staff needs another people to help to wear skate coaster is moved on to next span, sitting coaster works on again ... project progress is slow, and coefficient of safety is little, has potential safety hazard.The 2nd, hang attached cable with crane, but crane cost is high, remote mountain area is crossed over low-lying place and is had no usage and take artificial manyly, and same project progress is slower, is affected by human factors, and processing quality is difficult to guarantee.
Use artificial high-altitude to sit the private cable coaster in the conventional method, and when coaster fixedly can not directly pass through again during the cross-arm strong point to electric pole, cause that construction schedule is slow, labour intensity is large, the on-the-spot height of remote mountain construction is straggly serious, electric pole span span with a varied topography is large, and electric pole and the backguy depth of burying are difficult to reach " safety work order " requirement.When coaster during to the sag minimum point, the stressed maximum of both sides electric pole and backguy, backguy is easily loosening, makes the electric pole run-off the straight or skews, and very easily causes the high-altitude to fall and falls accident.Analogue almost all occurred repeatedly every year.
After adopting the aerial cable new method for erecting, the Novel cable hook runs into cross-arm when steel strand wire slide can not pass through, and has affected the work of setting up.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of easy to use, cost is low, can so that cable and hook be crossed over cross-arm stops, cross over smoothly trailing cable at steel strand wire and cross over support.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of trailing cable is crossed over support, comprise the leap beam, it is characterized in that: it is curved to cross over beam, crosses over the beam middle part main support is set, and the two ends of crossing over beam are provided for respectively connecting the connector of steel strand wire.
During use, main support is fixed on the cross-arm, is used for supporting the leap beam, the connector at leap beam two ends will be crossed over beam and connect together with steel strand wire, fit tightly steel strand wire so that cross over the beam two ends, cross on the beam so that cable clip can slide into from steel strand wire, pass through smoothly cross-arm.
Wherein preferred version is:
It is the stainless steel tube of 12mm-16mm that described leap beam adopts diameter, crosses over the beam two ends breach is set, and breach and steel strand wire diameter adapt.During fixing leap beam, steel strand wire stick into breach, so that cross over the more smooth nature of transition of beam and steel strand wire.
Described leap beam length is 500mm-600mm, highly is 40mm-60mm.
The beneficial effect that trailing cable leap support of the present utility model has is: arc is set crosses over beam, cross over the beam middle part main support is set, the two ends of crossing over beam are provided for respectively connecting the connector of steel strand wire, during use, main support is fixed on the cross-arm, is used for supporting the leap beam, the connector at leap beam two ends will be crossed over beam and connect together with steel strand wire, fit tightly steel strand wire so that cross over the beam two ends, cross on the beam so that cable clip can slide into from steel strand wire, pass through smoothly cross-arm.The utility model matches with novel hook, has solved for many years the empty cable of people's work area pulley fixing frame, the difficult problem that people and coaster can not directly pass through when crossing on the electric pole the fixing steel strand wire strong point.Realize setting up in the continuous span the empty cable of fixed mount and cross over smoothly simultaneously the fixedly steel strand wire strong point of electric pole and cross-arm.For site operation has brought convenience, improved operating efficiency, reduced the high-altitude and fallen and fall accident rate.
Description of drawings
Fig. 1 is embodiment 1 structural representation of the present utility model;
Wherein: 1, cross over beam 2, main support 3, connector 4, steel strand wire 5, cross-arm.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, it is curved to cross over beam 1, crosses over beam 1 middle part main support 2 is set, and the two ends of crossing over beam 1 are provided for respectively connecting the connector 3 of steel strand wire.
Crossing over beam 1 employing diameter is the stainless steel tube of 12mm-16mm, crosses over beam 1 two ends breach is set, and breach and steel strand wire 4 diameters adapt.During fixing leap beam 1, steel strand wire 4 stick into breach, so that cross over the more smooth nature of transition between beam 1 and the steel strand wire 4.
Crossing over beam 1 length is 500mm-60mm, highly is 40mm-60mm.
Main support 2 is selected the stainless steel band steel of diameter 4*40mm, and connector is selected the 10mm galvanized bolt.
Operation principle and use procedure:
During use, main support 2 is fixed on the cross-arm 5, be used for supporting leap beam 1, the connector 3 at leap beam 1 two ends will be crossed over beam 1 and connect together with steel strand wire 4, fit tightly steel strand wire 4 so that cross over beam 1 two ends, cross on the beam so that cable clip can slide into from steel strand wire, pass through smoothly cross-arm.
