Abstract
The utility model discloses a kind of leading screw applied on underground railway track to clamp support, including screw mandrel neck seat, active card groove seat, screw mandrel；By the way that screw mandrel neck seat and active card groove seat are arranged on into rail of subway both sides.Screw mandrel neck seat is connected to by being grounded stake, in active card groove seat, and no longer ground wire stake is welded on subway rail, avoids injury of the welding to subway rail.Further, screw mandrel neck seat and active card groove seat quickly can be connected to by one by screw mandrel and firmly subway rail is clipped in the middle, and when removing it is also that dismounting can be achieved by the disengaging of screw mandrel, so that the integral installation dismounting that the screw mandrel clamps support is efficient and convenient, it is easy to safeguard and changes.
Description
Technical field
It the utility model is related to a kind of screw mandrel applied on underground railway track and clamp support.
Background technology
Underground railway track mounted when being overhauled, it is necessary on rail track overhead contact net temporary ground wire cable and
Electrical verification cable.Existing mode is all directly to clamp track with clip, and in operation, clip may come off, to personnel and equipment
Damage.Particularly after anti-misoperation system is added, the temporary ground wire stake and electrical verification stake of anti-misoperation need to weld
It is connected on underground railway track, so underground railway track can be caused necessarily to injure, and is changing these temporary ground wire stakes and electrical verification
Also very inconvenient dismounting during stake.
Therefore a kind of new technical scheme is needed to solve the above problems.
Utility model content
The utility model provides a kind of leading screw applied on underground railway track and clamps support, it is therefore intended that easily by ground
Iron contact net temporary ground wire stake and electrical verification stake are arranged on rail of subway both sides, maintain easily replacing, and can reduce welding
When injury to rail of subway.
To reach above-mentioned purpose, the utility model can adopt the following technical scheme that：
A kind of leading screw applied on underground railway track clamps support, including screw mandrel neck seat, active card groove seat, screw mandrel；Institute
The bottom for stating screw mandrel neck seat is provided with the screw hole for extending transversely through screw mandrel neck seat, and is provided with the screw hole and coordinates with screw mandrel
Internal thread, and the top of screw mandrel neck seat is provided with the screw hole and the first wedge-shaped slot of facing movament neck seat；It is described
The bottom of active card groove seat is provided with the through hole for extending transversely through active card groove seat, and the top of active card groove seat is provided with through hole
And towards the second wedge-shaped slot of screw mandrel neck seat；At least one of which of the screw mandrel neck seat and active card groove seat, which is connected with, to be connect
Earth wire pile；One end of the screw mandrel includes screw mandrel head.
Further, the bottom of first wedge-shaped slot and the bottom of the second wedge-shaped slot are located at sustained height.
Further, the top surface of the screw mandrel neck seat is provided with to install the mounting hole of ground wire stake.
Further, the screw mandrel neck seat, active card groove seat are conductive
Beneficial effect：The beneficial effects of the utility model are no longer to set the fixing device of the clip class such as prior art
Active force is applied to rail of subway, is changed to by the way that screw mandrel neck seat and active card groove seat are arranged on into rail of subway both sides, and lead to
Rail of subway can be clipped in the middle by crossing the first wedge-shaped slot and the second wedge-shaped slot, be made easy for installation and safe.Meanwhile pass through ground connection
Line stake is connected to screw mandrel neck seat, in active card groove seat, and no longer ground wire stake is welded on subway rail, avoids welding pair
The injury of subway rail.Further, screw mandrel neck seat and active card groove seat quickly can be connected to by one by screw mandrel
And firmly subway rail is clipped in the middle, and be also that can be achieved to remove by the disengaging of screw mandrel during dismounting so that the screw mandrel
It is efficient and convenient to clamp the integral installation dismounting of support, is easy to safeguard and changes.

Embodiment
Incorporated by reference to shown in Fig. 1 and Fig. 2, the first wedge-shaped slot 1-1, screw hole 1-2 and peace are included on the screw mandrel neck seat
Fill platform 1-3.The first wedge-shaped slot 1-1 can be used for blocking rail of subway side.There is screw hole 1-4 on erecting bed 1-3 to pacify
Attaching earth wire pile.In the present embodiment, the internal thread to coordinate with screw mandrel is provided with the screw hole.
Incorporated by reference to shown in Fig. 3, the second wedge-shaped slot 2-1, through hole 2-2 are included in the active card groove seat.Second wedge
Shape groove 2-1 can be used for blocking rail of subway opposite side.The through hole 2-2 can be used for through screw mandrel.
Incorporated by reference to shown in Fig. 4, the screw mandrel 3-1 has a hexagonal screw mandrel head 3-2 for being used to tighten, and screw mandrel can be used for connecting
The screw mandrel neck seat and active card groove seat, and clamped in rail both sides.
By taking the embodiment shown in Fig. 5 as an example, the leading screw passes through the through hole 2-2 of the active card groove seat, and passes through iron
Rail 4-1 bottom, the second wedge-shaped slot 2-1 of the movable clamp groove is blocked into rail 4-1 bottom, while by screw mandrel 3-1 rotations such as
In the screw hole 1-2 of the screw mandrel neck seat, the first wedge-shaped slot 1-1 of the screw mandrel neck is also stuck in rail 4-1 bottom,
The hexagonal screw mandrel head 3-2, the first wedge-shaped slot 1-1 and the movable clamp groove of so described screw mandrel neck of the leading screw are screwed simultaneously
The second wedge-shaped slot 2-1 with regard to rail 4-1 bottom can be blocked.In this embodiment it is that in the erecting bed 1-3 of the screw mandrel neck
It is upper that temporary ground wire stake 4-2 is easily installed by screw hole 1-4 and screw (not shown).During dismounting, only six need to be reversely rotated
Angle screw mandrel head 3-2 can take down the screw mandrel neck seat and active card groove seat from rail 4-1..
The utility model implement the technical scheme method and approach it is a lot, described above is only of the present utility model
Preferred embodiment.It should be pointed out that for those skilled in the art, the utility model principle is not being departed from
