Abstract
Underground railway track contact net anti-misoperation electrical verification stake, including electrical verification pile body and electrical verification head are applied to the utility model discloses one kind；Electrical verification stake is integrally attached on rail by the installation portion of electrical verification pile body, and the contact bar of electrical verification head can be removed and be attached to progress electrical verification operation in the sleeve of electrical verification pile body again after cable under test is bolted on contact bar, will not so produce causes cable and the hidden danger of rail poor electric contact to produce as the clip produced in the prior art comes off, therefore the utility model can reliably connect electrical verification cable.
Description
Technical field
The utility model is related to underground railway track traffic power field, especially a kind of electrical verification stake applied in the field.
Background technology
Underground railway track, it is necessary to carry out electrical verification operation to the contact net in rail overhead, then could be mounted when being overhauled
Temporarily line.Clip is clamped rail during operation and then carries out electrical verification by existing electrical verification cable connection on a clip, in behaviour
Clip can be come off sometimes when making, and operation is impacted.Anti-misoperation system is both increased now with many subways, if only
Using clip can not also anti-misoperation be carried out to electrical verification operation.
Therefore need a kind of new technical scheme to solve the above problems.
Utility model content
The utility model provides a kind of anti-misoperation electrical verification stake for being applied to use during underground railway track contact net electrical verification.Can
Electrical verification cable is reliably connected applied in subway rail contact net electrical verification.
To reach above-mentioned purpose, the utility model can be adopted the following technical scheme that：
One kind is applied to underground railway track contact net anti-misoperation electrical verification stake, it is characterised in that：Including electrical verification pile body and electrical verification
Head；The electrical verification pile body includes installation portion, the column that self installation portion is upwardly extended and extends transversely through column and be fixed on column
Sleeve；
Electrical verification head include contact bar, be sheathed on be connected on contact bar and with the bush whorl nut, positioned at connecing
Bolt on feeler lever, the contact bar is provided with the screwed hole that bolt is screwed into.
Further, the sleeve outer wall is provided with the external screw thread coordinated with nut.
Further, the installation portion is provided with some mounting holes.
Beneficial effect：The beneficial effects of the utility model are, electrical verification stake can be integrally attached into iron by installation portion
On rail, and can will contact bar remove cable under test is bolted on contact bar after be attached in sleeve tested again
Electric operation, will not so produce causes cable and the hidden danger of rail poor electric contact to be produced as the clip produced in the prior art comes off
It is raw, therefore the utility model can reliably connect electrical verification cable.

Fig. 2 is the top view of electrical verification pile body
Fig. 3 is the sectional structure chart of electrical verification head in the utility model.
Fig. 4 is state diagram when the utility model electrical verification stake is used.
Embodiment
Below according to the reality described in the electrical verification head schematic diagram and Fig. 4 described in electrical verification described in Fig. 1, Fig. 2 schematic diagram, Fig. 3
The embodiment used illustrates embodiment of the present utility model.
The electrical verification pile body includes including electrical verification pile body and electrical verification head, and electrical verification shape body and electrical verification head are conductor.
Refer to Fig. 1 and Fig. 2, the electrical verification pile body include installation portion 11, the column 12 that self installation portion 11 is upwardly extended and
The sleeve 13 for extending transversely through column 12 and being fixed on column 12.The installation portion is provided with some mounting holes 14 that will install
Portion 11 can be fixed on rail by the cooperation of bolt and the mounting hole 14.
Referring to Fig. 3, described including contact bar 21, the spiral shell for being sheathed on contact bar 21 and being threadedly coupled with the sleeve 13
Mother 22 (it is corresponding, the outer wall of sleeve 13 be provided with nut coordinate external screw threads), positioned at the bolt 23 contacted on bar 21, it is described
Contact bar 21 is provided with the screwed hole that bolt 23 is screwed into.The bolt 23 is used to connection cables, after cable winds are on bolt 23,
Bolt 23, which is screwed tight, is fixed on cable between bolt 23 and contact bar 21.
Please in conjunction with shown in Fig. 4, electrical verification stake by the electrical verification pile body by welding or bolt in use, be fixed on rail
On 31, electrical verification cable 32 is connected on the electrical verification head by the bolt 23.The contact bar 21 is inserted into the sleeve
In 13, the nut 22 is screwed, electrical verification head is connected on the electrical verification pile body, electrical verification operation is finally carried out again.Terminate
During electrical verification, operation carries out reverse operating to more than.
The method and approach that the utility model implements the technical scheme are a lot, and described above is only of the present utility model
Preferred embodiment.It should be pointed out that for those skilled in the art, not departing from the utility model principle
On the premise of, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection domain of the present utility model.
Each part being not known in the present embodiment can use prior art to be realized.
