Abstract

The utility model belongs to the electric power part, and particularly relates to an insulating tube bus support fitting. A tube bus sleeve seat (6) and a lower tube bus sleeve (3) are hinged together through a hinge shaft (5) and are limited by a split pin (9); the hinge shaft (5) is arranged in a penetrating manner in a hinge shaft hole (6 - 1) of the tube bus sleeve seat (6); the lower end of the lower tube bus sleeve (3) movably penetrates through the hinge shaft (5); the lower tube bus sleeve (3) is provided with a lower sleeve O-shape groove (3 - 1) and a lower sleeve bolt hole (3 - 2); an upper tube bus sleeve (1) is arranged above the lower tube bus sleeve (3); the upper tube bus sleeve (1) is provided with an upper sleeve O-shape groove (1 - 1) and an upper sleeve bolt hole (1 - 2); the lower sleeve bolt hole (3 - 2) and the upper sleeve bolt hole (1 - 2) are fixed by a connecting bolt (2); and the lower sleeve O-shape groove (3 - 1) and the upper sleeve O-shape groove (1 - 1) are jointly embedded with an O-shape rubber ring (4). The insulating tube bus support fitting is simple in structure, convenient in installation and operation, and time-saving and labor-saving in production and installation, and can greatly reduce the cost of production and installation.

Description

Buses of insulation tubes supports gold utensil

Technical field

The utility model belongs to electric power accessory, and particularly a kind of buses of insulation tubes supports gold utensil.

Background technology

Buses of insulation tubes is the important link between main switch cabinet and the main transformer of wind power plant booster stations and electricity grid substation, and buses of insulation tubes support gold utensil is the key component of supports insulative pipe bus, buses of insulation tubes support gold utensil is directly connected to the stable operation of buses of insulation tubes and whole electrical network, buses of insulation tubes in the past supports gold utensil once dead after assembling with buses of insulation tubes, can not in vertical and horizontal direction, adjust to some extent, nor possesses the free-extension function of certain limit, because buses of insulation tubes produces the phenomenon of expanding with heat and contract with cold in running, this just need to often exceed 25 meters apart from time add place's retractor device, so just increase significantly manufacture installation cost, install and use also very inconvenient.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, can freely adjust, and the buses of insulation tubes with certain Telescopic supports gold utensil.

The technical scheme that the utility model technical solution problem adopts is: buses of insulation tubes supports gold utensil and comprises insulator, pipe bus block set, hinge, split pin, connecting bolt, O shape rubber ring, be characterized in that pipe bus block set and pipe bus are hinged and use split pin spacing with hinge between trapping, hinge is installed in the hinge axis hole of pipe bus block set, the lower end activity of trapping of pipe bus is installed on hinge, under pipe bus, put and be provided with trap O shape ring recess and the bolt hole of trapping, pipe bus is trapped and is equipped with on pipe bus and overlaps above, on pipe bus, put and be provided with cover O shape ring recess and upper cover bolt hole, trap and fix with connecting bolt between bolt hole and upper cover bolt hole, the common O shape rubber ring of insert in O shape ring recess and upper cover O shape ring recess of trapping.

The beneficial effects of the utility model are: it is simple that buses of insulation tubes supports hardware fitting structure, easy to install, manufacture installation time saving and energy saving, can in the time installing and using, automatically adjust, and there is within the specific limits free-extension function, simultaneously due to cover and pipe bus on pipe bus trap interior common insert O shape rubber ring can reduce short circuit time electric power impact, can significantly reduce manufacture installation cost owing to having saved retractor device.

Embodiment

Embodiment, with reference to accompanying

drawing

1,2, two fastening bolts 7 of pipe bus block set 6 use that buses of insulation tubes supports gold utensil are fixed on insulator 8, pipe bus block set 6 and pipe bus are trapped and between 3, are articulated and connected with hinge 5 and use split pin 9 spacing, hinge 5 is installed in the hinge axis hole 6-1 of pipe bus block set 6, and the 3 lower end activities of trapping of pipe bus are installed on hinge 5.Pipe bus is trapped and 3 is provided with trap O shape ring recess 3-1 and the bolt hole 3-2 that traps, pipe bus is trapped and is equipped with on pipe bus and overlaps 1 above 3, on pipe bus, overlap 1 and be provided with cover O shape ring recess 1-1 and upper cover bolt hole 1-2, trap fixing with connecting bolt 2 between bolt hole 3-2 and upper cover bolt hole 1-2, common O shape rubber ring 4 of insert in trap O shape ring recess 3-1 and upper cover O shape ring recess 1-1.

The using method that buses of insulation tubes supports gold utensil is: when use, pipe bus block set 6 use fastening bolts 7 are fixed on the insulator 8 of holder, O shape rubber ring 4 is sleeved on buses of insulation tubes, O shape rubber ring 4 is installed in traps in O shape ring recess 3-1 and upper cover O shape ring recess 1-1, be installed on upper cover bolt hole 1-2 and trap in bolt hole 3-2 with connecting bolt 2 and be locked, when use, buses of insulation tubes supports gold utensil equidistant support on buses of insulation tubes.
