Description
Technical field
A kind of master clamp of the utility model, belongs to the technical field of master clamp.
Background technology
At present, the supporting way of busbar is generally insulator support and common bus clip supports two large classes, when insulator supports busbar, need on busbar, punch, busbar is fixed on insulator with bolt, although this supporting way is firm, but because inevitably punching on busbar, so reduced the ampacity of busbar, in addition,, in the time that busbar expands with heat and contract with cold, the length variations of generation cannot be compensated, stress will all be applied on insulator, even causes in severe case insulator fracture;
When common master clamp supports busbar, usually, between master clamp and busbar, on busbar Width or thickness direction, can there is gap, make master clamp cannot on the Width of busbar and thickness direction, clamp busbar simultaneously; In the time that busbar passes through alternating current, because being applied to electric power on busbar be and the alternating force of electric current same frequency, so there will be busbar not stop to beat the situation of master clamp, and, because the conventional making material of common master clamp is hard insulation, so can produce larger vibrations noise, not only personnel are around caused to interference, also can affect the safe operation of equipment; In addition, the non-constant of the versatility of common master clamp, for the busbar of feature specification, specific configuration mode, must be equipped with specific master clamp, if change specification or the arrangement mode of busbar, must change master clamp, bring inconvenience to the work of buying and management busbar.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is: provide one can on busbar Width and thickness direction, clamp busbar simultaneously, and the extremely strong master clamp of versatility.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of master clamp, comprises at least one unit master clamp; Described unit master clamp comprises two primary and secondary row foldings that structure is identical, horizontal symmetrical arranges, described primary and secondary row folding comprises the collets that at least two in the vertical directions are stacked together, upper part and the end portion of each collets one side are provided with step locating surface, step locating surface between two adjacent collets surrounds a groove that blocks in the horizontal direction busbar jointly, and the distance between two horizontal planes up and down of described groove and the thickness of busbar adapt; In two described sub-master clamps, on each collets, all have vertically through hole, and the upper and lower of each primary and secondary row folding is provided with a gold utensil, described gold utensil is the connector of sheet, comprises the horizontal component and the vertical portion that are connected as a single entity, all has hole on the horizontal component of each gold utensil; Two gold utensils of the first double-screw bolt by all collets in a sub-master clamp and below being located thereon are worn together, and fasten by two nut clip, the second double-screw bolt is worn together all collets in another primary and secondary row folding and two gold utensils being located thereon below, and fastens by two nut clip; In the vertical portion of described gold utensil, also have hole, between the vertical portion of two gold utensils of primary and secondary row folding the same side, link together by the 3rd double-screw bolt and two nuts; Between described multiple unit master clamp, be parallel to each other or be arranged vertically, and between two adjacent unit master clamps by adjacent gold utensil is connected as a single entity to connect.
The cambered surface that the vertical plane contacting with the vertical side of busbar in described groove is evagination, in the time that busbar expands with heat and contract with cold, the size of busbar and change in displacement are adapted to be in above-mentioned groove the vertical plane of radian; Described the first double-screw bolt and first bolt of two nuts being mated and a nut replace; Described the second double-screw bolt and second bolt of two nuts being mated and a nut replace; Described the 3rd double-screw bolt and the 3rd bolt of two nuts being mated and a nut replace; Collets in described primary and secondary row folding are made by having flexible insulating material.
The utility model compared with prior art has following beneficial effect:
1, while use, busbar is put into the relevant position of unit master clamp, tighten respectively the nut at the first double-screw bolt, the second double-screw bolt two ends, by the gold utensil of unit master clamp upper and lower is applied to certain power, by middle collets be positioned at the busbar clamping that collets groove and its thickness and recess width adapt, realize the clamping on its thickness direction by busbar; Tighten the nut at the 3rd double-screw bolt two ends, gold utensil to master clamp the same side, unit applies certain power, corresponding gold utensil drives respectively the first double-screw bolt and the second double-screw bolt to exert pressure to collets, corresponding collets clamp the busbar being clipped in the middle, and have realized the clamping on its Width by busbar;
Master clamp in the utility model can clamp busbar on busbar width and thickness direction simultaneously, has reduced the vibrations degree of busbar, has reduced by busbar and has shaken the impact of the noise pollution causing on surrounding environment; In addition, can make be parallel to each other or be arranged vertically between multiple unit master clamp, be spliced into various multi-formly to adapt to the various installation requirements of busbar, improve the versatility of master clamp on largely;
2, the collets in the master clamp in the utility model are made by having certain flexible insulating material, clamp after busbar at master clamp, between collets and busbar, there will not be gap, the vibrations of busbar can absorb by resilient collets, and the vibrating noise that has more reduced busbar pollutes;
3, the cambered surface that the vertical plane contacting with the vertical side of busbar in groove in master clamp in the utility model is evagination, be that vertical plane in groove is made up of the inclined-plane of middle plane and both sides, under normal circumstances, by middle planar support busbar, in the time that busbar expands with heat and contract with cold, because collets clamp busbar, so the length variations of busbar can drive collets to turn over certain small angle, at this moment in collets, one of them inclined-plane of perpendicular approaches with busbar more, substitute original mid-plane and become new busbar supporting surface, the stress that busbar is expanded with heat and contract with cold compensates.
