Abstract

The invention discloses a bus support device, which comprises a support vertical post, a shock absorbing device and a fixing device, wherein the shock absorbing device is arranged at the upper end of the support vertical post; the shock absorbing device comprises a spring base, a spring end cover and a spring; the spring base is welded at the upper end of the support vertical post; the spring end cover is welded with the lower end of the fixing device; both ends of the spring are respectively connected with the spring base and the spring end cover; the fixing device comprises a bus support and a bus fixing clamper; the bus support comprises a support plate and a vertical plate; the lower end of the support plate is welded with the spring end cover; the vertical plate is welded at the upper end of the support plate; and the bus fixing clamper is movably connected with the vertical plate. According to the invention, the shock absorbing device is arranged between the support vertical post and the fixing device, so that the damage forces in various directions, generated by the energy, are decomposed and absorbed by utilizing the torsional, compressible and extensible properties of the spring arranged in the shock absorbing device, and the shock absorbing function is outstanding. The bus support device has the advantages of compact structure, fewer parts, low cost, convenience in installation and simplicity in maintenance.

Description

Busbar supporting device

Technical field

The present invention relates to a kind of bracing or strutting arrangement, especially a kind of bracing or strutting arrangement that prevents the bus vibrations belongs to the equipment for power transmission and distribution technical field.

Background technology

Bus be generator with transformer between the transmitting loop that is connected, whether the reliability of its safe operation is directly connected to whole electric power system stable, how to guarantee that the permanently effective safe operation of bus is vital problem.Buses of insulation tubes conventional mounting mode mainly is to adopt welding manner directly bus bar cupport to be welded on the support post, when the force majeure such as generation natural calamity, as earthquake, mud-rock flow, war etc. occur, adopt the welded and installed mode can not effectively decompose and absorb the energy of all directions of the phenomenons generations such as earthquake, mud-rock flow, war, very likely damage the insulation of bus, affect the safe operation of bus.

Summary of the invention

The purpose of this invention is to provide a kind of bracing or strutting arrangement, this device can effectively absorb, decompose the energy that the force majeure such as natural calamity produce, and guarantees the safe operation of bus.

The present invention is achieved by the following technical programs:

A kind of busbar supporting device comprises support post, damping device, fixture; Damping device arranges between support post and the fixture, damping device comprises spring pedestal, spring end cap, spring, spring pedestal is welded on the upper end of support post, and the spring end cap is welded on the lower end of fixture, and the two ends of spring are linking springs base, spring end cap respectively.

Purpose of the present invention can also further realize by following technical measures.

Aforesaid busbar supporting device, fixture comprise bus bar cupport, bus stationary fixture; Bus bar cupport comprises supporting plate, riser; The lower end of supporting plate and the welding of spring end cap, riser is welded on the upper end of supporting plate, bus stationary fixture and riser are flexibly connected, the side of riser is provided with groove, the bus stationary fixture comprises anchor clamps, lower clamp, the downside of lower clamp is provided with a groove, the groove both sides are provided with through hole, the groove of lower clamp is connected to the two sides of riser, the groove that passes the through hole of lower clamp and riser with bolt is flexibly connected lower clamp and riser, upper anchor clamps, respectively be provided with a half-round cross hole in the middle of the lower clamp, bus is arranged on anchor clamps, in the semicircle of lower clamp, upper anchor clamps are fixed on bus in the half-round cross hole by bolt; The support post upper end is provided with a plurality of damping devices; Fixture quantity is corresponding one by one with the bus radical.

The present invention arranges damping device between support post and fixture, use the destructive power that the damping device medi-spring can reverse, all directions of power generation are decomposed and absorbed to compressible, tensile characteristic, have good function of seismic resistance, compact conformation of the present invention, parts are few, cost is low, easy for installation, safeguard simple.

Advantage and disadvantage of the present invention will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is front view of the present invention;

Fig. 2 is left view of the present invention.

Embodiment

The invention will be further described below in conjunction with drawings and Examples.

The present invention includes support post 3, damping device 1, fixture 2; Damping device 1 arranges between support post 3 and the fixture 2, damping device 1 comprises spring pedestal 10, spring end cap 11, spring 12, spring pedestal 10 is welded on the upper end of support post 3, spring end cap 11 is welded on the lower end of fixture 2, the two ends of spring 12 are linking springs base 10 respectively, spring end cap 11, fixture 2 comprises bus bar cupport 21, bus stationary fixture 20, bus bar cupport 21 comprises supporting plate 210, riser 211, bus stationary fixture 20 comprises anchor clamps 201, lower clamp 202, the lower end of supporting
