Abstract
The utility model provides a special overlapping cable clamp for live line work, which comprises a plurality of BJL overlapping cable clamps each of which comprises an upper overlapping cable clamp, a lower overlapping cable clamp and a screw rod which connects the upper overlapping cable clamp and the lower overlapping cable clamp; a raised block is arranged on the upper overlapping cable clamp; and a fixed connecting plate is arranged on the raised block. The special overlapping cable clamp makes use of the fixed connecting plate to prevent the adjacent BJL overlapping cable clamps from overlapping with each other and to prevent each single cable clamp from rotating, and during the live overlapping operation, all the cable clamps can be overlapped at one time, thus improving the live overlapping quality and eliminating the hidden safety problem caused by construction quality.
Description
Technical field
The utility model relates to the special-purpose overlap joint of a kind of live line working wire clamp.
Background technology
The earth potential live operation of adopting also claims the insulating tool indirect operating at present, and the key operation project of wherein carrying out is carried out charged overlap joint for utilizing parallel groove clamp.Therefore, the processing quality of permanent wire clamp overlap joint in the live line working will produce bigger influence to the safe operation of overlapped points and circuit, user's lasting, stable power-supplying.Since the restriction of the charged operational method of standard, and do not have special charged overlap joint wire clamp, and we have to use the common overlap joint wire clamp of BJL type.There are the following problems in actual applications for the common parallel groove clamp of BJL type:
(1) utilize insulating bar bigger in holding screw intensity, operating personnel portion is not easy to control wire clamp;
(2) when carrying out charged overlap joint, can only observe and operate and put in place with the distance of operating personnel outside insulating bar length, just in constantly adjusting, revising " estimation puts in place ", and can not accomplish to utilize the design of wire clamp and constructional practicality and accuracy to accomplish " accurately putting in place ";
(3) in a single day on observing or operating, cause error, added some defectives of wire clamp itself, caused binding bad easily, the point of contact heating stays accident potential, and generation equipment obstacle finally is in operation, equipment breakdown can take place in severe patient, influences the stable operation of distribution.
Summary of the invention
Technical problem to be solved in the utility model is to provide the special-purpose overlap joint of a kind of live line working wire clamp, and overlap joint accurately puts in place, and is easy to operate, can improve the processing quality of charged overlap joint, eliminates safe hidden trouble.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the special-purpose overlap joint of a kind of live line working wire clamp, comprise several BJL type overlap joint wire clamps, described BJL type overlap joint wire clamp comprises the screw rod that overlaps wire clamp and following overlap joint wire clamp in overlap joint wire clamp, following overlap joint wire clamp, the connection, the described overlap joint wire clamp of going up is provided with projection, and described projection is provided with fixed connecting plate.
As preferably, described fixed connecting plate is provided with oval slotted hole, and described screw rod is located in the oval slotted hole.Utilize screw rod that fixed connecting plate and BJL type overlap joint wire clamp are fixed.
As preferably, described fixed connecting plate both sides are provided with baffle plate.Prevent to rotate.
As preferably, be provided with pad between described screw rod and the fixed connecting plate.The protection fixed connecting plate.
As preferably, described BJL type overlap joint wire clamp adopts 2.
Beneficial effect:
The utility model adopts technique scheme that the special-purpose overlap joint of a kind of live line working wire clamp is provided, utilize fixed connecting plate to prevent that 2 BJL type overlap joint wire clamps from superposeing mutually, prevent the rotation of monolithic clamping plate, when carrying out charged overlap joint, all can once overlap and put in place, improve charged overlap joint quality greatly, eliminated the potential safety hazard that stays because of construction quality problem.
