Utility model content
The purpose of this utility model is to provide one to meet national grid " earth work construction technology " requirement, improves the transmission line of electricity down conductor bending tool of downlead installment work efficiency.
The utility model discloses a kind of transmission line of electricity down conductor bending tool, it includes location-plate and the flexible handle being attached to, location-plate is provided with the position limiting structure for limiting downlead rotational freedom, flexible handle is provided with the line pressing component for backfin downlead, flexible handle can rotate freely around position limiting structure, to treat that bending downlead inserts clamping in position limiting structure, rotary moveable handle, line pressing component completes the bending of downlead.
Described position limiting structure includes retainer ring and the two pieces of vertical flat boards being welded in retainer ring, and two pieces of vertical flat boards are arranged symmetrically with about retainer ring median plane, and the lower end of retainer ring is welded in described fixed plate.
The inner side of one of described vertical flat board has been bolted adjustable plate.
Described flexible handle includes that loose collar and be fixed on the rod handle of loose collar outer wall, loose collar are placed on that described retainer ring is outer, can be relatively fixed ring rotates freely.
Described line pressing component is cylindrical bar, is parallel to described retainer ring and arranges, is positioned at described flexible handle one end near described loose collar.
Loss prevention shell that is co-axial and that can rotate it is cased with around its longitudinal center line outside described cylindrical bar.
Described location-plate is rectangular slab, and location-plate is provided with installing hole and fixing reinforced hole.
The installing hole of described location-plate is slotted hole.
Described location-plate has rubber layer.
The utility model proposes a kind of bending tool including location-plate and flexible handle, location-plate is provided with the position limiting structure for limiting downlead rotational freedom, flexible handle is provided with the line pressing component for backfin downlead, to treat that bending downlead is inserted in position limiting structure, rotary moveable handle again after being clamped by adjustable plate, line pressing component completes the bending of downlead.Can be good at ensureing the qualification rate of bending by utilization of the present utility model, reduce labor intensity, improve installation effectiveness low.
Meanwhile, in order to prevent from damaging the zinc coat on downlead surface in Forging Process, outside line pressing component, the loss prevention shell that can rotate is devised.
In order to make this utility model be applicable to the downlead of different-diameter, inside vertical flat board, it is removably connected with adjustable plate, by mobile adjustable plate or remove adjustable plate and regulate the interval between two columns, in order to mate the downlead of different diameters.
For the ease of installing, the installing hole of location-plate is designed as slotted hole.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of one preferred embodiment of this utility model.
Fig. 2 is the schematic side view of the present embodiment.
Diagram sequence number:
1 location-plate, 2 flexible handles, 3 rubber layers, 4 balls, 11 retainer ring, 12 found flat board, 13 adjustable plates, 21 loose collars, 22 rod handle, 23 cylindrical bars, 24 loss prevention shells.
Detailed description of the invention
As shown in Figure 1 and Figure 2, present embodiment discloses a kind of transmission line of electricity down conductor bending tool, it includes the location-plate 1 of rectangle, flexible handle 2 and rubber layer 3, and flexible handle 2 is connected on location-plate 1, and rubber layer 3 is positioned at location-plate 1 time.
Location-plate 1 be provided with for steel tower bottom install slotted hole and for strengthening the fixing reinforced hole fixed, location-plate 1 be fixedly arranged in the middle of retainer ring 11, two pieces of vertical flat boards 12 it are provided with in retainer ring 11, two found flat board 12 is arranged symmetrically with about a median plane of retainer ring 7, two stand and are removably connected with adjustable plate 13 on a piece in flat board 12, can regulate two by adjustable plate 13 and found the spacing between flat board 12.
Flexible handle 2 includes loose collar 21 and is fixed on the rod handle 22 of loose collar outer wall, loose collar 21 is placed on outside retainer ring 11, being provided with some balls 4 between loose collar 21 and retainer ring 11, it is possible to be relatively fixed ring 11 and rotate freely, loose collar 21, retainer ring 11 and ball 4 form ball bearing.Rod handle 22 enterprising loose collar 21 end is provided with the cylindrical bar 23 for backfin downlead, is cased with loss prevention shell 24 that is co-axial and that can rotate around its longitudinal center line outside cylindrical bar 23.
The present embodiment is when carrying out the bending of downlead, first location-plate is arranged on relevant position bottom steel tower, then downlead is stood from two and pass between flat board, downlead is clamped by adjustable plate, rotary moveable handle again, by the cylindrical bar backfin downlead on flexible handle, the bending of downlead can be completed as required.Operating process is simple, and can well ensure the qualification rate of bending, reduces labor intensity, and the present embodiment also has simple in construction simultaneously, from heavy and light, it is simple to the advantage carried.
