Abstract

The utility model relates to an overhauling platform for an isolating switch. The utility model comprises a ladder, and a base which is provided with an upper plate and a lower plate; the top of the ladder is provided with a platform, a protective bar, the top of which is provided with a loop ring, is inserted into a vertical pipe and positioned by a positioning pin arranged in the vertical pipe, the lower end of the ladder is fixedly connected with the upper plate of the base, two support rods are fixedly connected between the platform and the upper plate, and fasteners are arranged on the upper plate and the lower plate of the base. The utility model is held on a chassis of the isolating switch, and a safety belt is tied in the loop ring; therefore, the utility model has the characteristics of compact structure, simple structure, easy use, convenient carrying and high work safety.

Description

The isolating switch inspection platform

The utility model relates to a kind of inspection platform of substation equipment service kit, especially isolating switch.

In the past transformer station during maintenance of 220KV isolating switch, because of there not being the instrument of ascending a height reliably, it is very dangerous to work, Chinese patent CN2179466 disclosed " isolating switch maintenance ladder ", though solved the situation of the special-purpose instrument of ascending a height of 220KV isolating switch maintenance nothing, but be made of two bases, two cat ladders, horizontal ladder and pole-climbing four part assembly units because this maintenance is terraced, the gap is bigger, easily rocks.Secondly it is bigger to overhaul terraced volume, carries, transports inconvenience.Moreover when on the chassis that the base of maintenance ladder is fixed on isolating switch, need screw 8 bolts, it is not too convenient to install and remove.

The purpose of this utility model provide a kind of carry light, simple in structure, simple load and unload isolating switch inspection platform.

The utility model is that the technical scheme that achieves the above object is: a kind of isolating switch inspection platform, comprise ladder and have the base of upper and lower plate, it is characterized in that: the top of ladder is fixed with platform, the protection rod that the top has ring is inserted in the vertical tube, by the alignment pin location that is contained on the vertical tube; The lower end of ladder and the upper plate of base are connected, and also are fixed with two struts between platform and the upper plate, and securing member is arranged on the upper plate and lower plate of base.

For further improving the structural rigidity of inspection platform, between the vertical tube of strut, be fixed with reinforcement.

The utility model adopts the advantage after the technique scheme to be: 1. because this inspection platform has only a cat ladder, a platform and the integral body that the base welding constitutes, structure is very simple compact.Secondly this inspection platform volume is less, and weight is carried lightly only about 10Kg, and transportation, collection are also all very convenient.2. upper plate and the cat ladder because of the inspection platform base welds; and be welded with nut on the lower plate of base; the upper and lower plate holder of base is on the chassis of isolating switch during use; two bolts are screwed on the nut of lower plate, clamp the base of isolating switch, install and remove also very convenient; 3. owing to also be inserted with the protection rod of belt loop on the cat ladder; the workman can tie up to safety belt on one's body the enterprising line operate of ring, and can regulate the overhang of protection rod as required, and is safe and reliable.

Novel enforcement is further described to this reality below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the schematic side view of Fig. 1.

Fig. 3 is an another kind of structural representation of the present utility model.

Fig. 4 is the schematic diagram of base band muscle lower plate.

Fig. 5 is the A-A cutaway view of Fig. 4.

Isolating switch inspection platform shown in Fig. 1～5; the base that comprises ladder (5) and have upper plate (6), lower plate (9); the top of two vertical tubes (5-1) of ladder (5) and platform (3) welding; the protection rod (2) that the top has ring (1) is inserted in any one montant (5-1) of ladder (5); by alignment pin (4) location that is installed on the montant (5-1); alignment pin (4) can adopt dog screw or alternate manner, and protection rod (2) can be made telescopic adjustment as required.The welding of the lower end of two vertical tubes (5-1) of ladder (5) and the upper plate (6) of base can be as shown in Figure 1 that the ladder of inspection platform is a symmetrical structure, is applicable to the maintenance of GW-7-220 isolating switch; Also the ladder of inspection platform is a dissymmetrical structure as shown in Figure 3, and the two ends of short vertical tube (5-3) are welded on respectively on the cross bar (5-2) of the upper plate (6) of base and ladder (5), to be applicable to the maintenance of GW-4-220 isolating switch.Be welded with on two struts (10) between the upper plate (6) of platform (3) and base, to improve the bearing value of platform (3), this strut (10) can be arc or straight shape.For further improving the rigidity of structure of inspection platform, reinforcement (11) is welded between strut (10) and the vertical tube (5-1).Securing member is arranged on the upper plate (6) and lower plate (9) of base, can adopt screw threads to be combined on upper plate (6) or the lower plate (9); Also can the lower plate (9) shown in Fig. 4,5 can be band muscle lower plate (9) and be welded with two nuts (12), two bolts pass upper plate (6) and band muscle lower plate (9) and two nuts (12) and spin.

During use; upper plate of inspection platform base (6) and band muscle lower plate (9) are contained on the isolating switch chassis; two bolts (8) pass upper plate (6) and are screwed in the nut (12) of being with muscle lower plate (9); inspection platform is fixed on the chassis (7) of isolating switch; pull out and lock after protection rod (2) is adjusted to the appropriate location, safety belt ties up in the ring (1) of protection rod (2) upper end and gets final product work.

Claims
