Description
Technical field
This utility model relates to the line maintenance instrument of power department, is specially a kind of fall arrest earth terminal.
Background technology
During station, need power failure equipments incoming call side is carried out ground protection.At present, the earth terminal that transformer station uses uses wire clamp form, and owing to 500kV equipment wire is twisted wire, wire itself is relatively thick, can be thicker if twisted wire is lax, and ground wire is difficult to clamping, easily falls.Secondly, earth lead three is the biggest, and length is longer, and running into the weather such as strong wind in maintenance process easily has and swing by a relatively large margin, causes earth lead to fall.
Summary of the invention
The problem that this utility model easily falls for the interior earth lead that solves to stand now, it is provided that a kind of novel substation grounding the end of a thread.
This utility model adopts the following technical scheme that realization:
A kind of fall arrest earth terminal, including hook body, arranges line position folder in described hook body；Installing location spring by bearing pin in installing slip-off preventing block tongue, the root cavity of described hook body by latch in the root cavity of described hook body, under normality, location spring orders about slip-off preventing block tongue Guan Bi hook body；Described slip-off preventing block tongue the inner wears reset insulation stay cord.
During use, being installed on peg by hook, when needs hanging earthing conductor, earth terminal directly can be placed in wire upper end, operation maintenance personnel pulls down peg with strength can complete earth lead suspension.Now fall arrest block tongue automatically resets under the effect of location spring and closes hook, is locked by hook on wire, will not fall.When earth lead removed by needs, reset insulation stay cord of first leaving behind, pack up slip-off preventing block tongue, push-pull bar can remove earth lead then up.
This utility model has the advantage that
1, on the basis of existing hook, get final product improvement and installation fall arrest block tongue, make full use of existing resource, cost-effective.
2, easy to use, safe and efficient.
This utility model is reasonable in design, simple in construction, greatly reduces the probability that earth lead falls, and has ensured the safety of maintainer and being smoothed out of service work, and effect is obvious, has good market using value.
Accompanying drawing explanation
Fig. 1 represents overall structure schematic diagram of the present utility model.
Fig. 2 represents partial cutaway schematic of the present utility model.
In figure, 1-hook body, 2-line position presss from both sides, 3-slip-off preventing block tongue, and 4-reset insulation stay cord, 5-latch, 6-positions spring, 7-bearing pin.
Detailed description of the invention
Below in conjunction with the accompanying drawings specific embodiment of the utility model is described in detail.
A kind of fall arrest earth terminal, including main body hook 1, line position folder 2, slip-off preventing block tongue 3, reset insulation stay cord 4.
As it is shown in figure 1, arrange line position folder 2 in described hook body 1, line position folder (genus existing structure) is all set in existing hook, is used for clamping wire.
As shown in Figure 2, by latch 5, slip-off preventing block tongue 3 is installed in the root cavity of described hook body 1, by bearing pin 7, location spring 6 is installed in the root cavity of described hook body 1, under normality, location spring 6 orders about slip-off preventing block tongue 3 and closes hook body 1, now in the root cavity of the inner hook main body 1 of slip-off preventing block tongue 3, keep balance；Described slip-off preventing block tongue 3 the inner wears reset insulation stay cord 4, when opening hook, and drop-down reset insulation stay cord 4, drive slip-off preventing block tongue 3 to rotate counterclockwise along its latch 5, compress location spring 6 simultaneously, open hook.
During use, being installed on peg by hook, when needs hanging earthing conductor, earth terminal directly can be placed in wire upper end, operation maintenance personnel pulls down peg with strength can complete earth lead suspension.When earth lead removed by needs, reset insulation stay cord of first leaving behind, pack up slip-off preventing block tongue, push-pull bar can remove earth lead then up.
Finally it should be noted that; above example is only in order to illustrate the technical solution of the utility model and unrestricted; although being described in detail with reference to this utility model embodiment; it will be understood by those within the art that; the technical solution of the utility model is modified or equivalent; without departure from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
