Technical Field

The utility model relates to the field of power construction, in particular to a special tool designed for bending a large-diameter cable

Background

When the cable is bent, the cable is difficult to bend and the construction is difficult, a tool capable of bending the cable is required, so that the cable can be conveniently bent and the standard of the cable can be consistent; the tool for bending the cable is available in domestic market, but the bending radius is small and fixed, the bending radius of the cable is required to be standard bending according to the multiple of the diameter of the cable, the cable is not required to exceed standard excessive bending and damage an insulating layer, and the sharp edge of the fulcrum of the bending cable tool in the bending process moves relative to the insulating layer outside the cable, so that the outer surface of the cable is easy to scratch;

therefore, a novel bending tool which is applied to bending a large-diameter cable during power construction, is convenient and quick to bend, is standard in bending specification, and does not damage the insulating outer layer of the cable is urgently needed to be developed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a novel special tool for bending a large-diameter cable, which is convenient, quick, standard and free from damaging an outer insulating layer of the cable, is developed aiming at bending the large-diameter cable during power construction.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: this novel crooked instrument of big cable, the appearance divide into about three parts, and the middle part is opening frame shape instrument body down, and the material is lighter for aluminium, the handle is installed to the body side, facilitates the use, and upper portion is two fixed wheels and a driving wheel, the fixed wheel passes through the screw thread and installs on the instrument body, middle driving wheel, and the lower part is two perpendicular frames of instrument body and installs rotatable lead screw, the lead screw passes through screw drive one and removes the axle, it divides big footpath and path two parts to remove the axle, it passes the middle bar groove of instrument body, preceding to remove axle path part the driving wheel is installed on removing axle path terminal surface screw hole, through the interior hexagonal nut head of rotatory lead screw, can drive the driving wheel and go forward and retreat, details fixed wheel and driving wheel and lead screw structure: the fixed wheel has the same structure as the driving wheel and comprises an outer ring groove aluminum wheel, two bearings, a central small shaft and an inner and outer diameter snap spring for fixing the bearing position; the screw structure: the radial support of the screw rod is a copper sleeve arranged in mounting holes of two vertical frames of the tool body, flat push ball bearings are arranged at two ends of the screw rod, a self-locking outer hexagon nut is arranged at an auxiliary end of the screw rod and axially locks the screw rod in place, the screw rod cannot move axially but can flexibly rotate, the middle of the screw rod passes through a radial threaded hole at the large end of the moving shaft, and the screw rod rotates and can drive the moving shaft to move back and forth in a strip-shaped groove in the middle of the tool body, so that a driving wheel on the tool body is driven to move back and forth;

compared with the prior art, the utility model has the advantages that:

according to the novel large cable bending tool, the driving wheel of the pressing line can be quickly replaced, and the minimum radius of the smooth circular groove of the driving wheel determines the bending radius of the cable, so that the driving wheel is replaced according to the minimum bending radius required by the cable standard, and the cable is bent to meet the safety standard.

Second, this novel big cable bending tool, the fixed wheel of crooked cable and driving wheel ring channel are all very smooth, rotate very nimble, and during crooked cable, cable insulation surface layer and wheel ring channel face do not have relative movement, and protection cable insulation surface does not receive the damage.

Third, the driving wheel of the novel large cable bending tool is driven by the inner hexagon nut head at the main end of the rotary screw rod, so that the displacement can be controlled more accurately,

therefore, the bending angle can be controlled more accurately;

fourthly, this novel big cable bending tool volume is less, and is nimble convenient laborsaving in narrow and small space operation, lets must crooked cable press from both sides between driving wheel and fixed wheel, holds the instrument handle with the left hand, and the hexagon head is installed with the ratchet spanner to the right hand, and the cable can be crooked to hexagon nut head in the fast rotation lead screw.
