Description
Technical field
The utility model relates to hot line maintenance field, is specifically related to a kind of rotatable live line working machete jig combination tool.
Background technology
Live line working, refers to the operations such as the service without power-off carrying out on high voltage alive equipment.For ensureing the safe and reliable stable operation of electrical network, reduce the electric quantity loss bringing because of power failure defect elimination, charged for replacement transmission line, because of the insulator string of thunderbolt or outside destroy, is the main method of eliminating similar defect.At present, conventional machete jig generally comprise screw mandrel, insulated tension pole, front clamp, rear clamp and regulate front clamp and rear clamp between the crank handle of distance, while adopting conventional machete jig to change the insulator string in tension double-string, because of will by two insulator strings wherein a string suffered tension force transfer on machete jig, in the time that operating personnel tightens up screw mandrel, screw mandrel and insulated tension pole junction can produce torsion because of stressed, very easily make insulated tension pole twist off in operation process or produce other surprisingly, bringing very big security risk to charging equipment and operating personnel.
Utility model content
The purpose of this utility model is to provide one can prevent that screw mandrel and insulated tension pole junction from reversing because of stressed generation, avoid insulated tension pole to twist off in operation process or produce other surprisingly, guaranteeing the machete jig combination tool of charging equipment and operating personnel's safety.
The utility model for achieving the above object, is realized by the following technical solutions:
A kind of rotatable live line working machete jig combination tool, comprise screw mandrel, insulated tension pole, front clamp, crank handle, anti-slip thread locking cover, rear clamp, described front clamp is socketed on screw mandrel, rear clamp is socketed on insulated tension pole, one end of described screw mandrel is fixed with rotary connecting joint, one end of insulated tension pole is fixed with connecting pin, described rotary connecting joint is flexibly connected with connecting pin, described anti-slip thread locking cover is socketed on screw mandrel, and match with screw mandrel, described crank handle is fixedly connected with anti-slip thread locking cover, and crank handle is vertical with screw mandrel, front clamp is between anti-slip thread locking cover and rotary connecting joint.
Structure, the effect of anti-slip thread locking cover are similar to nut, for general nut, anti-slip thread locking cover has stronger anti-skidding effect, when use, also can replace with general nut, by anti-slip thread locking cover, can realize the distance adjustment of front clamp and rear clamp.When operation, shake crank handle, make anti-slip thread locking cover mobile, and then front clamp and rear clamp are blocked the two ends of insulator, suffered insulator tension force is transferred on machete jig, at present, the screw mandrel of traditional machete jig is to adopt to be fixedly connected with insulated tension pole, in rotating crank handle, insulated tension pole can produce a torsion thereupon, and insulated tension pole can produce torsional deformation, thereby affects the intensity of insulated tension pole itself, cause insulated tension pole very likely to be twisted off or break, lead to a disaster.The utility model is by increasing rotary connecting joint, connecting pin, because screw mandrel and rotary connecting joint are connected as a single entity, and can not produce synchronous rotation between rotary connecting joint, connecting pin, connecting pin can not rotate along with the rotation of rotary connecting joint, therefore, originally issuable torsion between screw mandrel and insulated tension pole, being rotated connector, connecting pin divides and takes off, insulated tension pole there will not be rotation, insulated tension pole only bears longitudinal pulling force, thereby ensure the structural stability of insulated tension pole, greatly reduced the possibility that insulated tension pole is pulled off.
In order to improve fail safe, increase the service life, further, being shaped as of described insulated tension pole is cylindrical.The shape of cross section of the insulated tension pole of tradition machete jig is square, and the possibility that this structure generation reverses, is out of shape, damages is larger, and changes into after cylindrical insulated tension pole, can effectively overcome these problems.
Further, on the screw mandrel between described front clamp and anti-slip thread locking cover, be socketed with buffering ring.Buffering ring can avoid front clamp directly to contact with anti-slip thread locking cover, plays the effect of the front clamp of protection, extends the useful life of machete jig.
In order to obtain better higher operating efficiency, further, as preferred version, the utility model also comprises ratchet, and described ratchet sleeve is connected on anti-slip thread locking and puts, and crank handle is fixedly connected with ratchet.Ratchet forms a speeder wrench together with crank handle, can greatly accelerate the service speed of crank handle, improves whole operating efficiency.
Further, described insulated tension pole is provided with multiple adjustment holes.In operation time,, rear clamp is fixed on insulated tension pole by adjustment hole, can be according to the length of setting insulator string, select different adjustment holes to regulate, workable, stability high and stressed evenly, have simple in structure, the feature of easy to use and flexible.
Further, described rotary connecting joint comprises a cylinder and a disk, cylindrical center line overlaps with the center line of disk, and cylindrical diameter length is less than the diameter length of disk, cylinder is fixedly connected with screw mandrel, being shaped as of described connecting pin is barrel-shaped, barrel-shaped bottom is provided with circular hole, the diameter length of circular hole is greater than cylindrical diameter length, and the diameter length of circular hole is less than the diameter length of disk, connecting pin is fixed on the bar head of insulated tension pole, and the disk of rotary connecting joint is positioned at connecting pin.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is by the basis of traditional machete jig, by increasing rotary connecting joint, connecting pin, because screw mandrel and rotary connecting joint are connected as a single entity, and rotary connecting joint, between connecting pin, can not produce synchronous rotation, connecting pin can not rotate along with the rotation of rotary connecting joint, therefore, originally issuable torsion between screw mandrel and insulated tension pole, be rotated connector, connecting pin divides to be taken off, insulated tension pole there will not be rotation, insulated tension pole only bears longitudinal pulling force, thereby ensure the structural stability of insulated tension pole, greatly reduce the possibility that insulated tension pole is twisted off or breaks.
(2) the utility model is by increasing ratchet, ratchet sleeve is connected on to anti-slip thread locking and puts, crank handle is fixedly connected with ratchet, and ratchet forms a speeder wrench together with crank handle, greatly accelerate the service speed of crank handle, and then improved whole operating efficiency.
(3) the utility model arranges multiple adjustment holes on insulated tension pole, when operation, rear clamp is fixed on insulated tension pole by adjustment hole, can be according to the length of setting insulator string, select different adjustment holes to regulate, workable, stability is high and stressed even, have simple in structure, the feature of easy to use and flexible.
