Abstract
The invention discloses a support used for isolation switch overhauling. The support comprises a mounting rack, a casing pipe, a support bar A, a support bar B, a cross bar and a pulley. The mounting rack is formed by an upper plate, a lower plate and a side plate connected to a same side edge of the upper plate and the lower plate. The casing pipe is a hollow structure. The casing pipe is fixedly arranged on an upper surface of the upper plate. The support bar A is arranged in the casing pipe. The support bar A and the casing pipe are connected in a fastening mode through a positioning bolt. A top end of the support bar A is hinged to a lower end of the support bar B. The support bar B can rotate 90 degree about a linkage point of the support bar A and the support bar B. An upper end of the support bar B is provided with the cross bar and a lower side of the cross bar is connected to the pulley. The structure is simple, the design is reasonable, on-site fixation and connection are convenient, the support is portable and flexible, dismounting is rapid and convenient and the support is safe and reliable.
Description
Technical field
The invention belongs to isolating switch maintenance field, specifically a kind of isolating switch maintenance support.
Background technology
Known, isolating switch is configured on main electrical scheme, form obvious fracture when ensure that circuit and overhaul of the equipments and live part is isolated, due to isolating switch do not have arc-control device and connecting-disconnecting function low, so during disconnecting switch operation, grid switching operation order must be observed, namely during power transmission, bus bar side of first closing isolating switch, next line side isolating switch that closes, finally close circuit breaker, has a power failure then on the contrary above-mentioned; Because isolating switch is generally outdoor acting, therefore need maintenance in use for some time or safeguard, at present, in the isolating switch overhaul process of electric power system, usually adopting aluminium alloy pole to carry out.Utilize the operation of aluminium alloy pole, pole is longer, and weight is large, four bracing wires of fixing pole, and the position of bracing wire is not easy to select, and not easily ensures safe distance, easily causes electric shock.Pole is high to be not easy to control, and easily causes the phenomenon of falling bar, and from charging equipment very close to, abnormally dangerous.Use pole to lift, poor stability, dangerous large, work occurs that danger often, and repair quality is qualified low, service kit complicated operation, inefficiency.
Summary of the invention
In order to solve problems of the prior art, the object of this invention is to provide a kind of isolating switch maintenance support.
In order to realize foregoing invention object, the present invention adopts technical scheme as described below:
A kind of isolating switch maintenance support, comprise installing rack, sleeve pipe, support bar A, support bar B, cross bar and pulley, described installing rack is by upper plate, lower plate and being connected to, side plate composition on the same side of lower plate, described sleeve pipe is hollow-core construction, sleeve pipe is installed on the upper surface of upper plate, support bar A is provided with in sleeve pipe, be fastenedly connected by bolt between support bar A and sleeve pipe, the top of support bar A and the lower end of support bar B hinged, and support bar B can rotate 90 degree with the pin joint of support bar A and support bar B, the upper end of support bar B is provided with cross bar, pulley is connected with in the downside of cross bar.
Further, the upper surface of described lower plate is provided with tapped blind hole, in tapped blind hole, is installed with puller bolt.
Further, described tapped blind hole is provided with at least two.
Further, described support bar A is provided with some tapped blind holes along its shaft direction, described bolt is through revolving after sleeve pipe in the tapped blind hole be located on support bar A.
Owing to adopting technique scheme, the present invention has following superiority:
Structure of the present invention is simple, reasonable in design, and the scene of being convenient to is fixedly connected with, light and flexible, and dismounting is quick and convenient, safe and reliable; By the puller bolt that lower plate is arranged, the present invention can be made to install firmly, and the isolating switch sling by pulley can unload electric pole easily, alleviates working strength, improves efficiency, and safety have also been obtained guarantee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-lower plate; 2-side plate; 3-upper plate; 4-sleeve pipe; 5-bolt; 6-support bar A; 7-pulley; 8-cross bar; 9-support bar B; 10 puller bolts.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of isolating switch maintenance support, comprise installing rack, sleeve pipe 4, support bar A6, support bar B9, cross bar 8 and pulley 7, described installing rack is by upper plate 3, lower plate 1 and being connected to, side plate 2 on the same side of lower plate forms, described sleeve pipe 4 is hollow-core construction, sleeve pipe 4 is installed on the upper surface of upper plate 3, support bar A6 is provided with in sleeve pipe 4, be fastenedly connected by bolt 5 between support bar A6 and sleeve pipe 4, the top of support bar A6 and the lower end of support bar B9 hinged, and support bar B9 can rotate 90 degree with the pin joint of support bar A and support bar B, the upper end of support bar B9 is provided with cross bar 8, pulley 7 is connected with in the downside of cross bar 8.
The upper surface of described lower plate 1 is provided with tapped blind hole, in tapped blind hole, is installed with puller bolt 10.
Described tapped blind hole is provided with at least two.
Described support bar A6 is provided with some tapped blind holes along its shaft direction, revolves in the tapped blind hole be located on support bar A6 after described bolt 5 passes sleeve pipe.
Upper plate on installing rack and lower plate, when specifically installing, are blocked the channel-section steel of isolating switch base by the present invention, then rotate puller bolt and hold out against channel-section steel, the present invention is firmly connected with channel-section steel; Whether then according to real work situation, support bar A is elongated to appropriate length, and selects to be rotated by support bar B, then utilize and one end of lifting rope is firmly connected isolating switch, the other end is walked around after pulley by operated by personnel; Structure of the present invention is simple, reasonable in design, and the scene of being convenient to is fixedly connected with, light and flexible, and dismounting is quick and convenient, safe and reliable; By the puller bolt that lower plate is arranged, the present invention can be made to install firmly, and the isolating switch sling by pulley can unload electric pole easily, alleviates working strength, improves efficiency, and safety have also been obtained guarantee.
