Abstract
The utility model discloses an insulation support for lower side contact of a contact rail. The insulation support for lower side contact of the contact rail comprises a groove channel embedded in a base side wall and a glass fiber-reinforced plastic L-shaped supporting seat which is connected through a T-shaped bolt, wherein the tail end of the glass fiber-reinforced plastic L-shaped supporting seat is provided with a threaded embedding piece in a mould pressing mode, a clamping jaw is connected through the threaded embedding piece and the bolt, and a cavity is formed by the tail end of the supporting seat and the clamping jaw in a matched mode and coincides with a contact rail tail wing. The insulation support for lower side contact of the contact rail achieves the installation of the small-space lower side contact of the contact rail, the clamping jaw and the supporting seat are connected through the bolt and the threaded embedding piece, operation is achieved through one wench, and therefore installation is convenient. The insulation support is simple to regulate, and convenient to install and maintain. The T-shaped bolt and the groove channel are connected in an anti-skidding mode, the position of the support seat is fixed accurately, and safety and reliability of operation are guaranteed.
Description
Technical field:
The utility model relates to the track traffic technical field, is specially to contact with insulation under the electric power system contact trackside in the urban track traffic to support.
Background technology:
Adopt the contact rail power supply mode in the urban track traffic when train power supply, need contact rail be supported, this bracing or strutting arrangement will guarantee that not only electric insulating also will be able to bear contact rail and comprise static and dynamic load.The existing insulation of contact is down supported, and material is that glass-felt plastic guarantees electric insulating; Body junction constitutes the L type, mainly is made up of support, bearing, claw three parts, and bearing and claw cooperate die cavity that matches with the contact rail tail shape of formation, in order to hold up the function that contact rail reaches support; This insulation is supported to be mainly used in installing space is not required, directly the installation on the level basis.Narrow and small when running into installing space, must be when sidewall to be installed, existing insulation is supported and can not be used.
The utility model content:
The technical matters that the utility model will solve is to support and can not install at sidewall to existing contact insulation down, and volume is bigger.Contact insulation support device under a kind of contact trackside is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Contact trackside contact down supports with insulation; Comprise the conduit that is embedded on the foundation side wall and pass through the bolted glass-felt plastic L of T type type bearing; The terminal stamped thread inserts of glass-felt plastic L type bearing; Through threaded insert and bolted connection claw is arranged, the end of bearing cooperates die cavity that coincide with the contact rail empennage of formation with claw.
Said conduit is anti-slip with the end face that contacts of T type bolt; Said glass-felt plastic L type bearing is connected through slotted hole and the T type bolt that is provided with; Said threaded insert termination is provided with the anti-rotation flange; The bolt lower end is provided with cushion block and stop washer, and the end of bearing and claw end are provided with slide block, and slide block and contact rail contact surface are cambered surface, and slider bottom is the anti-back boss structure, and the side is provided with the connection cylinder.
Method of application: at first, bearing through T type bolt with conduit is connected fixingly, slotted hole cooperates the pre-buried dimension limit of conduit, the bearing setting height(from bottom) is regulated through conduit, between bearing and the sidewall apart from finely tuning through pad.Then, contact rail lifted be placed on the bearing relevant position, claw is in place.Put cushion block, stop washer, bolt successively.At last, tight a bolt, stop washer one end plug is gone in the cushion block anti-rotation hole, and an end is held bolt cap tightly, sheds the power of lifting, and at this moment installation is supported in the contact insulation under the side, can realize its function.
The good effect of the utility model is:
1, the utility model has been realized the installation of contact down of contact trackside.
2, the utility model configuration design is ingenious, and compact conformation is suitable for the narrow and small environment of installing space; Claw is connected with the threaded insert mode through bolt with bearing, and is easy for installation.
3, the utility model uses conduit and insulation support and connection, has saved installing space, and the insulation support is regulated simple, is convenient to installation and maintenance, and T type bolt and conduit are anti-slip, accurate fixed bearing position, and accurately the fixed bearing position is guaranteed safe and reliable to operation.
