Abstract

The utility model discloses a 10kV insulation span frame, and the frame comprises supporting rods, stay wires, and an insulation seal grid. The number of the supporting rods is four, and the supporting rods are arranged in a rectangular shape. Each supporting rod is corresponding to six stay wires. The upper ends of the stay wires are respectively fixed at the upper and central parts of the supporting rods, and the lower ends of the stay wires are fixed on the ground. Four corners of the insulation seal grid are respectively fixed at the top of the corresponding supporting rod. The frame provided by the utility model improves the work efficiency and safety performance of the construction of a 10kV span live-line work of a line project, and greatly reduces the potential safety hazard of site operation.

Description

10kV insulating crossing structure
Technical field
The utility model relates to a kind of insulating crossing structure equipment.
Background technology
Guaranteeing that under the prerequisite that do not have a power failure of charged 10kV circuit, carrying out line project puts Construction of Tension Stringing, set up crossing frame final order ground be exactly to guarantee safety.Traditional 10kV crossing frame is made up of steel pipe and mao bamboon, and steel pipe has enough intensity, but must use insulating material when rules regulation is closed on 10kV alive circuit, mao bamboon is insulating material, but the intensity of mao bamboon material is relatively low, and service life is shorter, has potential safety hazard.
Summary of the invention
Set up for solving tradition the potential safety hazard that crossing frame exists, the utility model provides the insulating crossing structure that a kind of security performance is high, and its technical scheme of taking is as follows:
Comprise support bar, bracing wire and insulation block, support bar is four and is square arrangement, the corresponding six roots of sensation bracing wire of each support bar, and their upper end is separately fixed at top and the middle part of support bar, and lower end fixes on the ground, insulation four jiaos of block is separately fixed at the top of corresponding support bar; Each support bar is by upper pillar stand, lower pillar stand, detachable goat's horn bar and lifting device composition, the cross section of upper pillar stand and lower pillar stand is triangle, the bottom of upper pillar stand is plugged in lower pillar stand, goat's horn bar flare and be fixed on the top of upper pillar stand, lifting device by promoting line, be fixed on the draw ring of upper pillar stand bottom, the lower sheave that is fixed on the top sheave at lower pillar stand top and is fixed on lower pillar stand bottom forms, the upper end that promotes line is fixed on draw ring, and its lower end is walked around top sheave and lower sheave successively.
The utility model will insulate to net by bracing frame and hang up, by being sealed with insulation nettle across 10kV circuit below newly-built circuit, thereby insulation block sinks to causing the not enough hidden danger that produces of safe distance in order to prevent wire, and bracing frame epimere can be enclosed within hypomere, be beneficial to transportation and storage, the detachable goat's horn on bracing frame can prevent from running line.What the utility model had improved line project while crossing over the construction of 10kV alive circuit does efficiency and security performance altogether, potential safety hazard while greatly reducing site operation, guarantee newly put lead wire and earth wire and alive circuit fail safe, have easy to carry, materials are less, security performance high.
Accompanying drawing explanation
Fig. 1 is the on-the-spot schematic diagram that uses of the present utility model;
Fig. 2 is the structural representation of support bar part of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, support bar 1 is four and is square arrangement, be arranged in the both sides of crossed line, the corresponding six roots of sensation bracing wire 2 of each support bar 1, their upper end is separately fixed at top and the middle part of support bar 1, and lower end fixes on the ground, increase the stability of support bar 1, insulation four jiaos of block 3 is separately fixed at the top of corresponding support bar 1.
As shown in Figure 2, each support bar 1 is by upper pillar stand 4, lower pillar stand 5, detachable goat's horn bar 6 and lifting device composition, the cross section of upper pillar stand 4 and lower pillar stand 5 is triangle, and the bottom of upper pillar stand 4 is plugged in lower pillar stand 5, goat's horn bar 6 flares and be fixed on the top of upper pillar stand 4.Lifting device by promoting line 7, be fixed on the draw ring 8 of upper pillar stand 4 bottoms, the lower sheave 10 that is fixed on the top sheave 9 at lower pillar stand 5 tops and is fixed on lower pillar stand 5 bottoms forms, the upper end that promotes line 7 is fixed on draw ring 8, and its lower end is walked around top sheave 9 and lower sheave 10 successively.
When use, pull at and promote line 7, make upper pillar stand 4 be promoted to desired location from lower pillar stand 5, then fix upper pillar stand 4, finally carry out top block, safe distance when unwrapping wire will be guaranteed in the position of block between wire and alive circuit.
