Abstract

The utility model provides a foundation bolt structure for a railway sleeper, which comprises a bolt and a nut. The foundation bolt structure for the railway sleeper is characterized in that the end portion of a threaded rod of the bolt is provided with a screw cap which comprises a cylindrical inner cavity with one side sealed and a threaded counter bore on the sealed face of the cylindrical inner cavity, the nut is arranged in the cylindrical inner cavity of the screw cap in clearance mode, and the threaded rod of the bolt is matched with the threaded counter bore. A circular blocking plate is sleeved on the threaded rod of the bolt, and the outer diameter of the blocking plate is larger than or equal to the diameter of the cylindrical inner cavity. The screw cap of the foundation bolt structure for the railway sleeper covers the threaded rod and the nut, and simultaneously the blocking plate can prevent dust and rain on the ground from entering into the cylindrical inner cavity of the screw cap from the position under the screw cap, thereby protecting foundation bolts from being corroded by rain and rusting, improving reliability of connection of foundation bolts, simultaneously reducing overhauling frequency of railway maintenance workers and further reducing labor intensity.

Description

The stone bolt structure that is used for railway ash pillow
Technical field
The utility model relates to a kind of bolt arrangement, relates in particular to the stone bolt structure that is used for railway ash pillow.
Background technology
The stone bolt of railway ash pillow is exposed in the open air, the work under bad environment of stone bolt, and it is in rainwater and the dust for a long time; Easy rust corrosion has reduced the switching performance of stone bolt, has influenced the safety that railway ash pillow uses; Simultaneously; Because the easy rust corrosion of stone bolt, so the railroad maintenance personnel are higher to the frequency of its maintenance, increased railroad maintenance personnel's working strength.
The utility model content
The technical problem that the utility model solves is: a kind of stone bolt structure that is used for railway ash pillow is provided, can avoids stone bolt to be got rusty by the rainwater burn into.
The technical scheme of the utility model is: a kind of stone bolt structure that is used for railway ash pillow; Comprise screw bolt and nut; It is characterized in that the threaded rod end of said bolt is provided with a nut, this nut comprises the cylindrical cavity and the screw-threaded counterbore that is positioned at the cylindrical cavity sealing surface of a face closure; Said nut gap is dropped in the cylindrical cavity of nut, and the threaded rod of said bolt matches with said screw-threaded counterbore; Be with an annular baffle on the threaded rod of said bolt, the external diameter of this baffle plate is equal to or greater than the diameter of said cylindrical cavity.
The interior diameter of said baffle plate equals the diameter of the threaded rod of said bolt.
Said baffle plate is between the head and nut of bolt.
The beneficial effect of the utility model is: the nut of the utility model covers threaded rod and nut; Baffle plate can prevent that the rainwater on dust and ground from entering into the cylindrical cavity of nut from the nut below simultaneously; Therefore can avoid stone bolt to be got rusty by the rainwater burn into; Improved the reliability that stone bolt connects, reduced railroad maintenance personnel's repair rate simultaneously, and then reduced labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the nut structure sketch map in the utility model;
Fig. 3 is that the A of Fig. 2 is to sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment one
