The specific embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention and beneficial effect are further described.
As depicted in figs. 1 and 2, a kind of GIS installs maintenance with the driving of sliding type gantry, mainly comprises girder 1, support beam 13, top slide rail 2, electronic sliding machine 3, electronic zip strip cucurbit 4, supply cable 10, control line 14, controller 15, triangular supports 17, the roller 21 etc. of hanging.Wherein, described girder 1 is in the intermediate lateral setting of described gantry driving, and described support beam 13 vertically is arranged on the two ends of described girder 1, is used for supporting described girder 1.Described top slide rail 2 is welded on the below of girder 1, and electronic sliding machine 3 can move along slide rail 2 by being suspended on carriage walking device 8 and cooperating of top slide rail 2 below of top slide rail 2; There is anti-derailing end plate 9 at slide rail 2 two ends in top, prevent the dolly accidental; Lock rail device 6 and safety device 7 are also arranged on the running gear 8, stop control in case guarantee to be in operation, electronic sliding machine 3 can be arbitrarily not mobile again, guarantees to hang the safety of drawing work; The electronic zip strip cucurbit 4 that hangs is housed on the electronic sliding machine 3, can moves up and down, GIS equipment is hung draw; Electronic sliding machine 3 provides power supply by supply cable 10 and the power lead 16 of receiving external source, and supply cable 10 is suspended on by anchor fitting 11 on the iron wire 12 of girder 1 side, moves and mobile with dolly 3, guarantees power supply reliability; One cover control part 5 is arranged on the electronic sliding machine 3, and the movement that the user can be by the control line 14 that connects and 15 pairs of electronic sliding machines 3 of controller and chain and tackle block 4 rise and fall and control, and normally hang pulling process.
Girder partly is that the triangular supports 17 by both sides supports, and triangular supports 17 is higher than on-the-spot GIS battery limits height, and the width between the both sides guarantees to be applicable to the scene also greater than on-the-spot GIS battery limits width.Two rollers 21 are equipped with in every side triangular supports 17 bottoms, and are fixing by roller anchor fitting 23, are furnished with brake equipment 22 simultaneously, and when guaranteeing to guarantee light movement, the unexpected slip can not appear in the driving of described gantry.
Three rectangular steel pipes 18 of triangular supports 17 constitute the rectangle hollow structure for adopting spill steel 19 and steel plate 20 welding, and this structure both can guarantee enough load-bearing properties, had alleviated device total weight, the dismounting of more convenient device and combination simultaneously again greatly.
In the present embodiment, because girder 1, both sides triangular supports 17 all adopt the design of simple science, rectangular steel pipe 18 adopts spill steel 19 and steel plate 20 welding to constitute the rectangle hollow structure, and use control line 14 and 15 pairs of electronic sliding machines 3 of controller and electric chain to hang and draw cucurbit 4 to control, make the integral structure miniaturization, whole driving volume is little, in light weight.Adopt girder both sides triangle steel structure support 17 simultaneously, replace fixed supporting track, can be in the indoor flexible movement of GIS, use is affected by environment little.The steel structure of each several parts such as gantry driving girder 1, triangular supports 17 adopts the Combination Welding plate to be connected with high strength bolt, can for convenience detach, assembling, to use flexibly, and a driving can be satisfied whole substations needs.This driving can be easily hung GIS equipment at the substation scene and is drawn, and plays the purpose of increasing work efficiency, saving manpower.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive, and the apparent variation of being extended out thus or the change still be among protection scope of the present invention.
