Abstract
The utility model discloses a dismounting tool for a GW17B-252J disconnecting switch. The dismounting tool comprises channel steel and a puller bolt, the upper side surface of the channel steel is provided with a threaded hole, the puller bolt penetrates through the threaded hole, and the front end of the puller bolt is provided with a compression sheet. The dismounting tool employs the channel steel, and the side surface of the channel steel is provided with the puller bolt, so that the tool can be fixed to the disconnecting switch via the puller bolt; and at a position crossing the dead center of the disconnecting switch, the tool is fixed to a connecting lever of the disconnecting switch, so that the connecting lever is fixed at the dead center of the connecting lever, thereby effectively preventing a pull bar in a conductive tube of the disconnecting switch from fracture due to the fact that the connecting lever is rapidly separated from a closing position. The dismounting tool is simple in structure and operation and worthy of popularization and application, and can be maximally practical under the same resource conditions.
Description
Technical field
The utility model belongs to isolating switch maintenance technique field, is specifically related to a kind of dismantling device of GW17B-252J isolating switch.
Background technology
Along with economic development, power supply reliability requires also more and more higher.On-the-spot to the Installation and Debugging time of equipment, also The faster the better, and GW17B-252J isolating switch uses in electric power system because of its good performance in a large number in electric power system.But before assembling isolating switch when contact tube, easily connecting lever is from closing position quick acting switching-off, cause the fracture of isolating switch contact tube draw-in bar, although but existing solution, but most method clumsinesses, not only take time and effort but also inefficiency, the bad phenomenon that causes contact tube fracture occurs to control often, therefore need isolating switch dismantling device a kind of not only efficient but also contact tube draw-in bar fracture can prevent before assembling isolating switch contact tube time.
Utility model content
The purpose of this utility model is to provide a kind of dismantling device of simple in structure, the easy and simple to handle and GW17B-252J isolating switch that efficiency is high.
To achieve these goals, the scheme adopting is: a kind of dismantling device of GW17B-252J isolating switch, comprise grooved steel plate and puller bolt, and described grooved steel plate upper side arranges screwed hole, described puller bolt runs through screwed hole, and described puller bolt front end arranges clamping piece.
Described puller bolt is wing bolt.
Described grooved steel plate inwall arranges rubber layer.
Described clamping piece is connected with puller bolt by roller bearing.
Described grooved steel plate upper side two ends arrange sponge protective layer.
The utility model adopts grooved steel plate and the mode of puller bolt is set in its side, it can be fixed on this device on isolating switch by puller bolt, at the dead point place excessively of isolating switch, this device is fixed on to its connecting lever place, make connecting lever be fixed on connecting lever dead point place, thereby can effectively prevent that connecting lever is from closing position quick acting switching-off, cause the fracture of isolating switch contact tube draw-in bar; Adopt dish-shaped bolt that user can be fixed this device by the effect of palm under not by the condition of instrument, thus by connecting lever fixed placement at dead point place; At grooved steel plate inwall, rubber layer is set, has increased the frictional force of contact-making surface, also can protect the phenomenon that can not damage because of hard contact isolating switch in the time using this device; At grooved steel plate two ends, sponge protective layer is set, has ensured that grooved steel plate upper side contacts with connecting lever as soft contact, the impression of having avoided direct contact to cause; Connect pressure strip and puller bolt by roller bearing; make in the process that tightens puller bolt not produce stiction between itself and pressure strip; protect the useful life of puller bolt and pressure strip; the utility model is simple in structure easy and simple to handle; in equal resources supplIes, county has brought into play its practical value to greatest extent, is worthy to be popularized and applies.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is side structure schematic diagram of the present utility model,
Structural representation when Fig. 2 is the utility model work.
Embodiment
As depicted in figs. 1 and 2: a kind of dismantling device of GW17B-252J isolating switch, comprise grooved steel plate 1 and puller bolt 3, described grooved steel plate 1 upper side arranges screwed hole 7, and described puller bolt 3 runs through screwed hole 7, and described puller bolt 3 front ends arrange clamping piece 5.
Described puller bolt 3 is wing bolt.
Described grooved steel plate 1 inwall arranges rubber layer 2.
Described clamping piece 5 is connected with puller bolt 3 by roller bearing 4.
Described grooved steel plate 1 upper side two ends arrange sponge protective layer 6.
In the time of dismounting GW17B-252J isolating switch, in the time that connecting lever 10 runs to dead point 8, be arranged on isolating switch by this device, connecting lever 10 is fixed on to 3 places, dead point, then isolating switch is taken off or installed, prevent that its quick acting switching-off from causing the fracture of contact tube 9, not only improved efficiency, and ensured fail safe.
The utility model adopts grooved steel plate and the mode of puller bolt is set in its side, it can be fixed on this device on isolating switch by puller bolt, at the dead point place excessively of isolating switch, this device is fixed on to its connecting lever place, make connecting lever be fixed on connecting lever dead point place, thereby can effectively prevent that connecting lever is from closing position quick acting switching-off, cause the fracture of isolating switch contact tube draw-in bar; Adopt dish-shaped bolt that user can be fixed this device by the effect of palm under not by the condition of instrument, thus by connecting lever fixed placement at dead point place; At grooved steel plate inwall, rubber layer is set, has increased the frictional force of contact-making surface, also can protect the phenomenon that can not damage because of hard contact isolating switch in the time using this device; At grooved steel plate two ends, sponge protective layer is set, has ensured that grooved steel plate upper side contacts with connecting lever as soft contact, the impression of having avoided direct contact to cause; Connect pressure strip and puller bolt by roller bearing; make in the process that tightens puller bolt not produce stiction between itself and pressure strip; protect the useful life of puller bolt and pressure strip; the utility model is simple in structure easy and simple to handle; in equal resources supplIes, county has brought into play its practical value to greatest extent, is worthy to be popularized and applies.
The above; it is only preferably embodiment of the utility model; these embodiments are all the different implementations based under the utility model general idea; and protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
