Between angle it is constant, generally 90 °, when causing to install in circular tunnel, the extended line direction of hanging bolt is directed to justify
The heart, for one side hanging bolt there are component, stress is bad；On the other hand, to the more demanding of construction and installation Adjustment precision,
When adjusting not in place, screw rod or nut unbalance stress will lead to.Currently, to solve the above problems, mainly adopting in practical projects
Setting angle is adjusted with gasket or cushion block.When using lock washer scheme, to reach ideal connection status, to the essence of lock washer
More demanding, the otherwise unbalance stress of screw rod or nut is spent, under the long-term severe working environment of urban track traffic, is easy
Existing fatigue, fastening ability decline；Using spherical cushion block scheme, adjustment difficulty can be reduced, but will increase the weight of integral hanging,
And above two scheme can not all adjust the angle of hanging bolt, can not fundamentally improve the stress of hanging bolt.
Utility model content
The technical issues of the utility model solves just is to provide the adjustable angle between a kind of hanging bolt and firm banking
Overhead contact line connect pedestal.
In order to solve the above technical problems, the utility model proposes technical solution are as follows: including have fixing bolt and suspention
The firm banking of bolt, the firm banking are provided with attachment spacers, and it is convex that attachment spacers is equipped with the first screw hole, the first tooth form
It rises；The upper end of hanging bolt is sheet ring head, and the lower end of hanging bolt is threaded rod, and sheet ring head is equipped with and the first screw hole
The second toothed projections thinking matched second screw hole, matching with the first toothed projections, the first connection bolt and the first connection spiral shell
Mother connects attachment spacers with sheet ring head.
Its additional technical feature are as follows: the front of the attachment spacers is provided with the anti-of the first toothed projections or attachment spacers
Face is provided with the obverse and reverse two sides of the first toothed projections or attachment spacers while being provided with the first toothed projections；Sheet annular
The reverse side that the front of head is provided with the second toothed projections or sheet ring head that match with the first toothed projections is provided with and the
It the obverse and reverse two sides of the second toothed projections or sheet ring head that one toothed projections match while being provided with and the first tooth
The second toothed projections that shape protrusion matches；
The attachment spacers, sheet ring head are circle.
Overhead contact line connection pedestal provided by the utility model is in use, first pass through the first spiral shell for the first connection bolt
Hole, the second screw hole connect attachment spacers with sheet ring head, and the first attaching nut is screwed on the first connection bolt and is not twisted first
Tightly.Then firm banking is fixed on the predetermined position of tunnel wall surface by fixing bolt, adjusts hanging bolt and connection gasket
Vertically downward, the first attaching nut is tightened for angle between piece, the lower end for making hanging bolt, the first toothed projections and the second tooth form
Protrusion occlusion.Overhead contact line with insulator and wire clamp is passed through to the threaded rod of the second attaching nut and hanging bolt lower end
It is connected and fixed.Overhead contact line provided by the utility model connects pedestal, passes through the angle tune between hanging bolt and attachment spacers
It is whole, the connection angle between firm banking and overhead contact line can be easily adjusted, keeps hanging bolt vertically outstanding with contact net
Connection is hung, the installation accuracy of contact net system is improved, improves the whole stress of firm banking.As needed, attachment spacers is being just
The reverse side that face is provided with the first toothed projections or attachment spacers is provided with the obverse and reverse of the first toothed projections or attachment spacers
Two sides is provided with the first toothed projections simultaneously；The front of sheet ring head is provided with the second tooth to match with the first toothed projections
The reverse side of shape protrusion or sheet ring head is provided with the second toothed projections to match with the first toothed projections or sheet ring head
Obverse and reverse two sides be provided with the second toothed projections to match with the first toothed projections simultaneously.And attachment spacers, sheet
Ring head is circle, easy to connect.
