Abstract
The invention discloses an insulating cross arm with movable arc grooves, which comprises insulating cross arms, an insulating support pipe and a regulating arm, wherein a lead screw is sleeved in the insulating support pipe, and the lead screw and the insulating support pipe are screwed in a threaded mode; the upper end of the lead screw is connected with the lower end of a connector; left and right ends of the connector are respectively connected with one end of one insulating cross arm; one end of the regulating arm is connected with the middle of each insulating cross arm, and the other end of the regulating arm is respectively connected with clamps; the clamps are fixed on the outer surface of the insulating support pipe; at least two fixed buckles are also fixed on the outer surface of the insulating support pipe; fixed chains are arranged on the fixed buckles; and the movable arc grooves are formed on all the insulating cross arms. The insulating cross arm has the characteristics of low cost, light weight and the like, is easy to install and convenient to operate, and can improve the safety coefficients and work efficiency of live-wire work in the state of ground potential greatly and reduce the danger coefficients of operating personnel simultaneously.
Description
One, technical field: the present invention relates to a kind of 10KV distribution earth potential live operation field, particularly relate to a kind of insulator crossarm that has portable deep-slotted chip breaker.
Two. background technology: at present, state net company progressively improves the requirement of power supply reliability, it is also more and more stricter to require for client's service standard to power supply enterprise, and reduce the user have a power failure area, reduce the most remarkable feasible modes such as customer outage hours and carry out livewire work exactly.Livewire work is that with high content of technology, a safe skill is strict, and the line maintenance method of remarkable in economical benefits.By research and improvement to the livewire work Method and kit for, to improving livewire work efficient, expand charged job area undoubtedly, can play good effect.The suburb, Zhengzhou is with a varied topography than the urban district, and many charged work job site is subjected to the influence insulation of landform to tremble the arm car can't be close, can not implement medial potential working, thereby often adopt the earth potential working method to carry out charged work.Suburb, Zhengzhou power grid construction standard is consistent with the urban district now, and the 10KV main line adopts the JKLYJ-240 insulated wire more, and LGJ-185 bare wire more originally is heavy.And the lifting of the charged insulator crossarm that uses now partly is to be traction with rope band, is difficult to the lead of slinging, and the power tool heaviness has increased the weight of operating personnel's labour intensity in addition.
Three. summary of the invention:
Technical problem to be solved by this invention is: overcome the prior art deficiency, provide a kind of simple and reasonable, be connected firmly, elevating capacity height and the low insulator crossarm that has portable deep-slotted chip breaker of labour intensity.
Technical scheme of the present invention is: a kind of insulator crossarm that has portable deep-slotted chip breaker, contain the insulator crossarm arm, insulation supporting tube and regulating arm, described insulator crossarm arm is provided with fixed deep-slotted chip breaker, be set with leading screw in the described insulation supporting tube, the two screw-type spins together, described leading screw upper end is connected with the lower end of a connector, the two ends, the left and right sides of described connector are connected with an end of a described insulator crossarm arm respectively, the middle part of each described insulator crossarm arm is connected with an end of a described regulating arm, the other end of described regulating arm and clamp connection, described clip is fixed on the external surface of described insulation supporting tube, also be fixed with at least two fixedly buckles on the external surface of described insulation supporting tube, described fixedly buckle is provided with fixedly chain; Be provided with portable deep-slotted chip breaker on each described insulator crossarm arm.
By bolt and adjusting handle and described clamp connection, by aluminum alloy materials made respectively by described adjusting handle for the other end of two described regulating arms.Described leading screw top is provided with at least one locating hole.
Described insulator crossarm arm is made by epoxy resin board, and described insulation supporting tube is made by the epoxy resin pipe, and described regulating arm is made by the epoxy resin pipe.
The invention has the beneficial effects as follows:
1, the present invention adopts screw structure, lead is wasted time and energy, the not portative shortcoming of live line tool heaviness in traditional slinging with the rope band traction before having solved livewire work, can greatly improve earth potential live job safety coefficient and operating efficiency, reduce operating personnel's danger coefficient simultaneously.
2, insulator crossarm arm of the present invention is provided with portable deep-slotted chip breaker, even the intrinsic cross-arm inclined position of cement concrete bar causes separation nonstandard, still can use this instrument to carry out operation, thereby use very convenient.In addition, this instrument overall weight meets the requirement of the livewire work bearing capacity on 10KV cement concrete bar, safety factor height.
3, regulating arm of the present invention is provided with the adjusting handle, can regulate its length, and then can regulate the levelness of insulator crossarm arm effectively.
4, the present invention have install simple and easy, cost is low, in light weight, safety factor is higher, save time, characteristics such as easy to operate, it is applied widely, be particularly useful for earth potential live operation on the 10KV overhead wire concrete bar, can save for 1/3 time than traditional approach in equal ambient conditions operation, thereby, have good economic benefit after the popularization.
