Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use, is convenient to the overhead ground wire line lifter that overhead ground wire and wire clamp thereof are checked, safeguarded and change.
The overhead ground wire line lifter that the utility model relates to has a base, the middle part is provided with groove under base, be provided with the feed screw nut transmission mechanism in the base bilateral symmetry, the leading screw of feed screw nut transmission mechanism vertically runs through base and is connected with in the leading screw lower end carries the line iron chains, and the nut of feed screw nut transmission mechanism is positioned at the base plate top of base and is connected with the nut support assembly in the nut lower end.
Above-mentioned overhead ground wire line lifter, described nut support assembly is that the nut lower end of described feed screw nut transmission mechanism is connected with adapter sleeve by on the leading screw that is enclosed within the feed screw nut transmission mechanism and be supported on bearing pedestal on the base, be located at the thrust bearing in the bearing pedestal and constitute by nut and bearing pedestal loose joint and the adapter sleeve that is pressed in above the thrust bearing.
Above-mentioned overhead ground wire line lifter, nut outer wall middle part at the feed screw nut transmission mechanism is evenly equipped with draw-in groove, be positioned at the draw-in groove place in the nut of feed screw nut transmission mechanism outside and be arranged with rotating seat, on rotating seat, be provided with boosting-rod and front end and be inserted into very heavy in the draw-in groove.
The utility model has the advantages that: simple in structure, easy to use, base can be sitting on the iron tower tower head by the groove that is located on the base, by the feed screw nut transmission mechanism with carry the line iron chains and overhead ground wire can be mentioned fast, be convenient to overhead ground wire and wire clamp thereof are checked, safeguarded and change the security performance height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the part of Fig. 1 sends out figure big;
Fig. 3 is the A-A cutaway view of Fig. 2.
Among the figure: base 1, base plate 101, groove 102 is carried line iron chains 2, leading screw 3, nut support assembly 4, nut 5, draw-in groove 501, thrust bearing 6, bearing pedestal 7, nut 8, adapter sleeve 9, rotating seat 10, very heavy 11, boosting-rod 12, gland 13.
Embodiment
As shown in the figure, the utility model has a base 1, be provided with groove 102 at 1 time middle part of base, be provided with the feed screw nut transmission mechanism in base 1 bilateral symmetry, the leading screw 3 of feed screw nut transmission mechanism vertically runs through base 1 and is connected with in leading screw 3 lower ends carries line iron chains 2, and the nut 5 of feed screw nut transmission mechanism is positioned at base plate 101 tops of base 1 and is connected with nut support assembly 4 in nut 5 lower ends.Described nut support assembly 4 is that described nut 5 lower ends are fixed with adapter sleeve 9 grafting and by jackscrew by on the leading screw 3 that is enclosed within the feed screw nut transmission mechanism and be supported on bearing pedestal 7 on the base 1, be located at the thrust bearing 6 in the bearing pedestal 7 and constitute by nut 8 and bearing pedestal 7 loose joints and the adapter sleeve 9 that is pressed in above the thrust bearing 6.
Nut 5 outer walls middle part at the feed screw nut transmission mechanism is evenly equipped with draw-in groove 501, is positioned at draw-in groove 501 places in described nut 5 outsides and is arranged with rotating seat 10 by gland 13, is provided with boosting-rod 12 and front end and is inserted into very heavy 11 in the draw-in groove 501 on rotating seat 10.
During use, base 1 is ridden on the iron tower tower head by groove 102, to carry line iron chains 2 lower ends and pin overhead ground wire by U-bolt, rotate rotating seats 10 by boosting-rod 12 when shifting the load of overhead ground wire and drive nuts 5 rotations, make on the leading screw 3 and move, the loading of overhead ground wire is born by base 1 and leading screw 3, so just can be checked, safeguard and change overhead ground wire and overhead ground wire wire clamp.After checking, safeguard or changing, slowly transfer leading screw 3, the loading that makes overhead ground wire gets final product by becoming to be born by overhead ground wire wire clamp and iron tower tower head.
