Description
Technical field
The present invention relates to electric power safety fixture fields, and in particular to a kind of short circuit earthing clamp.
Background technology
With the continuous transformation continued to develop with the method for operation of power network, the interruption maintenance operation on ultra-high-tension power transmission line
It is increased.When line maintenance is carried out, according to《Safety》With standard operating procedure requirement, hung up properly immediately after electricity is tested
Short-circuit grounding wire, then carries out the work of defect processing again.Short circuit earthing clamp (also known as conductor wire end card) be it is a kind of dedicated for
The important component that the transmission pressure temporary short-circuit of power failure is grounded, its dependable performance just can guarantee that ultra-high-tension power transmission line has a power failure and examine
The safety repaiied, prevents incoming call suddenly or neighbouring high voltage alive equipment from producing harm of the induced voltage to human body.
The short circuit earthing clamp that current each grid company is used mainly have spirally, duck tongue type, flat and impacting type.
The chucking power that produces compares balance when duck tongue type is due to clamping wire, and compares and be easy to operation and widely use.Its primary structure
It is made up of a hook, two tongue pieces, two tension springs and insulating bar or insulating cord, action bars or insulating cord and hook phase
Connection, hook is with two clamping parts and connects the bending section of clamping part, two tongue pieces are positioned opposite and its one end respectively with
The flexible connection of two clamping parts is linked up with, the other end is stretched into the groove that bending section is provided with, and forms splay jaws, this structure
Earthing clamp is when for hanging wire, and wire starts to make two tongue pieces along different when entering corresponding with its size position of jaws
Direction is rotated, until two tongue pieces make elastic force hook to be fixed on wire because tension spring is produced, that is, completes hanging wire mistake
Journey.
But, the top for folding place, i.e. herringbone that rear wire is located at two tongue pieces is hung up properly, because high-tension line is in family
In external environment, wire by can produce vibrations, wave can influence be grounded line card reliable hook, ground connection line card can also be acted in wind-force
Lower loosening or slippage, overturn grounding hook, or even are come off from wire, cause temporary short-circuit ground connection invalid or failure,
When wrong power transmission or induced electricity it cannot be guaranteed that operating personnel is safe, often occur to get an electric shock or fall during induced electricity etc. great dead
The generation of accident is died, therefore there is major defect in current short circuit grounding cable clip structure, there is great potential safety hazard.
Therefore, present applicant has proposed a kind of technical scheme of the short circuit earthing clamp with locking anti-loose function, increasing
Add blocking device to improve security, but the program still has structure complex, the problems such as reliability is not enough.
Therefore, how existing short circuit earthing clamp is improved, it is overcome above-mentioned problem, be this area
Technical staff's problem urgently to be resolved hurrily.
The content of the invention
It is a kind of simple in construction it is a primary object of the present invention to provide, it is active in one's movements, easily operation, and clamping is reliable just
In locking, the short circuit earthing clamp unlocked.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of short-circuit grounding wire be easy to locking, unlocked
Folder, including hook and blocking device, it is characterised in that：The blocking device includes lock piece and tensioning member, and the lock piece turns
Dynamic to be connected on the hook, the tensioning member is arranged between the lock piece and the hook, and the lock piece is described
When being rotated on hook, with a mutation boundary, the lock piece is in the mutation boundary left pivot movement, and the tensioning member is forced
The lock piece is to rotation on the inside of the hook, and when the lock piece is rotated on the right side of the mutation boundary, the tensioning member is compeled
Make the lock piece to rotation on the outside of the hook；
Under original state, the lock piece is on the left of the mutation boundary, when wire enters the hook, promotes described
Lock piece rotates to rotation on the outside of the hook, and the lock piece and does not break through the mutation boundary, when the wire enters completely
When entering the hook, the lock piece is in the presence of the tensioning member to rotation, the short-circuit grounding wire on the inside of the hook
Folder is in blocking, and limitation wire skids off the hook；By pulling the lock piece, make the lock piece to the hook
Outside is rotated, and breaks through the mutation boundary, continues to rotate on the outside of the hook in the presence of the tensioning member, described short
Road earthing clamp is in unlocking condition, it is allowed to which wire skids off the hook.
As an improvement, the hook includes clamping part, installation portion, sliding bar and elastic component, the sliding bar is fixedly mounted
In the installation portion lower end, the clamping part is slideably positioned on sliding bar, and the elastic component is arranged at the clamping part and institute
State between sliding bar, for forcing the clamping part upward sliding, the blocking device is arranged on the installation portion.
Further improve, be provided with the top of the lock piece under arc groove, blocking, the arc groove and wire
Contradict.
It is preferred that, it is provided with anti-abrasion pad at the arc groove.The setting of anti-abrasion pad can reduce abrasion of the wire clamp to wire,
Also the frictional force between wire clamp and wire can be increased, the possibility skidded off is further reduced.
As reasonable design, the lock piece afterbody is provided with unlocking suspension ring, and the unlocking suspension ring are used to connect unlock rope.
Preferably, the tensioning member and the elastic component use spring structure.
Further preferably, the tensioning member is two, and positioned at the lock piece both sides.On the one hand increase tensile force, makes
Action is sensitiveer, on the other hand improves security, and in the case of a tensioning member failure, another stretching can also play drawing
The effect of stretching, is one of dual fail-safe.
Compared with prior art, the advantage of the invention is that：The blocking device of this programme is similar to the spike knot of bicycle
Structure, it is only necessary to will hook alignment wire, firmly one draw, wire with regard to can push open lock piece enter hook, while lock piece turn round into
Row locking is, it is necessary to when unlocking, then firmly pulls wire is pressed from both sides, and makes wire promote clamping part to be slided away from lock piece direction, until wire
No longer contacted with lock piece, now pull lock piece to hook outside rotate, when lock piece break through mutation boundary after, its automatically after
Continue and rotated to hook outside, and be permanently affixed to outermost locations (avoiding the need for hauling unlocking rope always), now wire clamp is in
Unlocking condition, wire clamp can just depart from from wire.Its is easy to operate, and clamps very reliable.
