Abstract
The utility model relates to a jacking device for an intensive busway. The jacking device is characterized by comprising a body, wherein a connecting plate is arranged at one side of the body, a connecting slot is arranged at the other side of the body, an elongated slot is arranged below the connecting slot, a nut is arranged in the elongated slot, and a jacking bolt penetratively arranged on the body is connected with the nut. When the jacking device is used, the upper end and the lower end of each of two side plates of the intensive busway are respectively provided with a cover plate, and jacking devices are oppositely arranged in slot openings at the upper end and the lower end of each of the side plates of the intensive busway, wherein the slot openings are formed by fins; the first row of fins at the upper end and the last row of fins at the lower end of each of the two side plates of the intensive busway are spliced with the connecting slot of the body; the connecting plate of the jacking device body is spliced with limiting slots of the cover plates; and fixed connection between the cover plates and the side plates can be achieved by rotating the jacking bolts of the jacking devices to further realize the purpose that a plurality of copper bars are firmly clamped between the two side plates. The jacking device for the intensive busway, disclosed by the utility model, has the advantages of simple structure, convenience for assembly and disassembly, firm connection, high short-circuit current withstanding capability and the like.
Description
Technical field
The utility model relates to the power distribution field, more particularly, is that a kind of concentration bus duct is used holding device.
Background technology
Bus duct is the electric wire erecting device that power distribution is used, and bus duct is divided into intensive and two kinds of air types from insulation mode.Concentration bus duct since plurality of advantages such as good heat dissipation, ampacity are big, compact conformation receive praises from customers.But concentration bus duct is that packaging technology is complicated than the shortcoming of air type bus duct, and precision prescribed is high.China's concentration bus duct assembling mode has two kinds at present: first kind is that two blocks of side plates connect becoming one after the busbar clamping with screw; Then cover plate is connected on the side plate with bolt or rivet; Owing to adopt a large amount of punchings and use respective numbers tap rivet syndeton on side plate, the cover plate; Greatly influenced the attractive in appearance of bus duct, be eliminated basically at present; The second way is maximum a kind of of present domestic use, after being about to busbar, side plate and fixing with frock clamp, again cover plate is followed closely a riveting with side plate with self-pierce riveting and becomes; Its shortcoming is to be not easy to operation, time-consuming; Cost is high, and efficient is low, and main shortcoming is; Self-pierce riveting nail riveted joint is on-dismountable syndeton, in case do over again dismounting cover plate and side plate are just scrapped.
Summary of the invention
The purpose of the utility model is the shortcoming that overcomes prior art, provides a kind of simple in structure, and installation, convenient disassembly are connected firmly, and the high concentration bus duct of tolerance short circuit current is used holding device.
The purpose of the utility model is realized by following technical proposals: a kind of concentration bus duct is used holding device; It is characterized in that: it comprises body; Side on body is provided with connecting plate, is provided with link slot at opposite side, be positioned at link slot below be provided with elongated slot; Be built-in with nut at described elongated slot, the puller bolt that is threaded onto on the body is connected with described nut.
When the concentration bus duct of use the utility model is used holding device; All be equipped with cover plate at concentration bus duct biside plate upper and lower end; Be positioned at notch homogeneous phase that concentration bus duct biside plate upper and lower end forms by fin to being equipped with holding device; The head of concentration bus duct biside plate upper end arranges end row's fin of fin and lower end and the link slot of holding device body is pegged graft; The connecting plate of holding device body and the stopper slot of cover plate are pegged graft, and just can realize being connected of cover plate and side plate through the puller bolt that rotates holding device, and then realize that plurality of rows copper bar firm grip is between biside plate.Have simple in structurely, install, convenient disassembly, be connected firmly tolerance short circuit current advantages of higher.
Description of drawings
Fig. 1 looks sketch map for the concentration bus duct of the utility model with holding device structure master.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Fig. 3 looks sketch map for the right side of Fig. 1.
Fig. 4 is that the concentration bus duct of the utility model is with holding device user mode sketch map.
Among the figure: 1 cover plate, 2 holding devices, 3 copper bars, 4 side plates, 5 link slots, 6 puller bolts, 7 nuts, 8 notches, 9 bodies, 10 elongated slots, 11 connecting plates.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1-Fig. 3; The concentration bus duct of the utility model has body 9 with holding device 2; Side on body 9 is provided with connecting plate 11, is provided with link slot 5 at opposite side, be positioned at link slot 5 below be provided with elongated slot 10; Be built-in with nut 7 at described elongated slot 10, the puller bolt 6 that is threaded onto on the body 9 is connected with described nut 7.Body 9 the bests of holding device are aluminium alloy extrusions, according to the current class needs, can be cut into respective length during use.Puller bolt 6 is connected the quantity of securing member can decide according to the quantity of concentration bus duct copper bar with nut 7, and puller bolt 6 adopts 1-3 right with nut 7 usually.
With reference to Fig. 4; The concentration bus duct that uses the utility model is during with holding device 2; All be equipped with cover plate 1 at concentration bus duct biside plate 4 upper and lower ends; Be positioned at notch 8 homogeneous phases that concentration bus duct biside plate 4 upper and lower ends form by fin to being equipped with holding device 2, the head of concentration bus duct biside plate 4 upper ends arranges end row's fin of fin and lower end and pegs graft with the link slot 5 of holding device body 9, the stopper slot grafting of the connecting plate 11 of holding device body 9 and cover plate 1; Just can realize being connected of cover plate 1 and side plate 4 through the puller bolt 6 that rotates holding device 2, and then realize that plurality of rows copper bar 3 firm grip are between biside plate 4.
The concentration bus duct of the utility model is merely an embodiment with the embodiment of holding device, and those skilled in the art duplicating and improving without creative work, all belongs to the scope of the utility model claim protection.
