Be provided with bearing in described axis hole, the inner hole sleeve of described bearing is contained on described turning cylinder, and the inner of described turning cylinder is provided with limited step, and its outer end is provided with captive nut.
Or described turning cylinder is provided with bearing, and the external diameter of described bearing is sleeved in the mounting hole on described removable framework, and the inner of described turning cylinder is provided with limited step, and its outer end is provided with captive nut.
The beneficial effects of the utility model are:
1, the utility model adopts the specification coiling and the portable mobile that are grounded line with the duplexing font wire spool of handle and the removable framework of U-shaped, realizes the standardized administration of transformer substation grounding wire.
2, the material of the utility model wire spool and removable framework and size can meet the requirement of whole group of grounding jumper loading and coiling, intensity is good, wire spool on mobile framework can convenient for assembly and dismounting, when wire spool assembles architecturally, easily can rotate wire spool coiling grounding jumper by swinging handle, laborsavingly to save time.
3, the removable framework of the utility model adopts apery engineering telescopic bar and forward type to mention handle double design in short-term, and bottom is equipped with roller, and can pull out pull bar direct pull during carrying grounding jumper, running into step can mention movement in short-term, convenient and swift.
4, the utility model is reasonable in design, structure is simple, reduce field labor intensity and increasing work efficiency, can configure in substation and organize wire spool more, after grounding jumper coils, directly disassemble unified depositing from removable framework, convenient management, it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing illustrates:
Fig. 1 is the structural representation of portable ground wire winding device;
Fig. 2 is the right elevation of ground wire winding device portable shown in Fig. 1.
detailed description of the invention:
Embodiment: see in Fig. 1, figure, 1-wheel shaft, 2-roller, 3-underframe, 4-stand, 5-end face framework, 6-turning cylinder, 7-wire-wrap board, 8-pull bar, 9-crank, 10-nut, 11-supporting leg, 12-connecting panel.
Portable ground wire winding device comprises removable framework and wire spool, removable framework is made up of the stand 4 at two intervals, underframe 3 and pull bar 8, wherein: the bottom of removable framework is provided with wheel shaft 1, the two ends of wheel shaft 1 are provided with roller 2, wire spool is fixedly formed by the end face framework 5 at two ends and the wire-wrap board 7 of centre, the end face framework 5 at two ends is provided with corresponding axis hole, the middle part of removable framework is provided with turning cylinder 6, wire spool is fixed on turning cylinder 6 by axis hole suit, and the end face framework 5 of outer end is provided with crank 9.
End face framework 5 is H-shaped framework, is made up of two risers and three transverse slats, and middle transverse slat is provided with axis hole; Wire-wrap board 7 has two at least, and along the axisymmetrical of axis hole.Be provided with at least two connecting panels 12 between two stands 4, one of them connecting panel 12 is provided with turning cylinder 6; The outer end of underframe 5 is provided with downward supporting leg 11.Removable framework is formed by tube bending, and its upper end arranges U-shaped handle.
Be provided with bearing in axis hole, the inner hole sleeve of bearing is contained on turning cylinder 6, and the inner of turning cylinder 6 is provided with limited step, and its outer end is provided with captive nut 10.Or turning cylinder 6 is provided with bearing, and the external diameter of bearing is sleeved in the mounting hole on connecting panel 12.
Crank 9 and wire-wrap board are threaded connection, can dismounting, and pull bar 8 be antenna telescopic structure, can change length, and the upper-end bent of pull bar 8 formation U-shaped.
During work, removable framework is pulled to move to correct position, the one ends wound of grounding jumper is fixed on wire-wrap board 7, then rotate crank 9, wire spool is rotated, and then by retracting regular for grounding jumper on wire spool, finally, remove nut 10, directly whole wire spool and grounding jumper together can be placed on storehouse, be convenient to take out when using next time.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
