Abstract

The utility model relates to a clamping type insulating steel support for a fishtail plate. The clamping type insulating steel support comprises a steel support body, an insulator, a support back plate, a back plate fixing sleeve, a fishtail plate fixing sleeve, a fishtail plate fixing sleeve gasket, the clamping fishtail plate and a fastening part. The clamping type insulating steel support is reasonably in structure, convenient to install and suitable for the circumstance that the upper portion of a lower contact type contact rail and the limit space of metro vehicles are narrow and small or other circumstances that a traditional mode of installing the contact rail on an upper clamping jaw can not be achieved, and achieves clamping-type installation of the contact rail on the fishtail plate by effectively utilizing the space of the position of a web of the contact rail.

Description

The clipping insulation steel bracket of a kind of fish plate
Technical field
The utility model belongs to contact type contact rail system under city traffic track, is specifically related to the clipping insulation steel bracket of a kind of fish plate.
Background technology
In City Rail Transit System, electric traction vehicle running rail one side is provided with the contact rail to vehicle transferring electric power.Contact rail is the vitals of electric power supply system for subway, gets the difference of stream mode according to vehicle from contact rail, and the mounting means of contact rail can be divided into contact, lower contact and three kinds of modes of side contacts.The contact rail of application mostly is lower contact at present, on by steel bracket body and the molecular insulating support of insulation, the claw that is provided with opening is installed, and the contact rail flange of rail is suspended in claw, and claw part protrudes from contact rail top.
But for vehicle gauge and the narrow and small extraordinary circumstances of contact rail upper space, the above space of contact rail upper limb is not allow any parts to invade, traditional claw is installed contact rail mode and cannot be addressed this problem, once invade vehicle gauge, hazardous accidents very easily occurs in subway system operational process.Therefore claw cannot be placed in the above space of contact rail upper limb in this case.
Summary of the invention
The utility model provides a kind of fish plate clipping insulation steel bracket, for the situation of vehicle gauge and contact rail upper limb insufficient space provides feasible and contact rail mounting bracket easily, avoid taking the situation of contact rail upper space installation contact rail, ensure to leave enough spaces between contact rail system and vehicle gauge, ensured train driving safety.
The clipping insulation steel bracket of a kind of fish plate, it is characterized in that, contact rail (1) relies on two clamping fish plates (4) by fish plate fixed cover (2) and fish plate fixed cover pad (3) interval to support, and pass backboard fixed cover (5) by fastener and be fixed on set lagging (6), it is upper that set lagging (6) is fixed on insulator (7) by fastener, and insulator (7) is fixed on steel bracket body (8).
Contact rail (1) web place need be provided with long trough hole, and fish plate fixed cover (2) can therefrom pass and level and smooth parallel motion in its space.
Use fish plate fixed cover pad (3) to regulate contact rail (1) and the gap value that clamps fish plate (4) lower bevel.
The beneficial effects of the utility model: the utility model provides feasible and contact rail mounting bracket easily for the situation of vehicle gauge and contact rail upper limb insufficient space, the situation of having avoided taking contact rail upper space contact rail being installed.Expand the range of use of contact rail in City Rail Transit System, contact rail has been used in city track traffic engineering more flexible.The clipping insulation steel supporting structure of this fish plate is simply compact, cheap.

Detailed description of the invention
The clipping insulation steel bracket of a kind of fish plate shown in Fig. 1 and Fig. 2, contact rail (1) relies on two clamping fish plates (4) by fish plate fixed cover (2) and fish plate fixed cover pad (3) interval to support, clamping fish plate (4) is in contact with one another and plays a supporting role with contact rail (1) two ramp, and clamping fish plate (4) and contact rail (1) two lower inclined plane leave the sliding resistance of gap guarantee contact rail minimum.Pass backboard fixed cover (5) by fastener again and be fixed on set lagging (6) above, it is upper that set lagging (6) is fixed on insulator (7) by fastener, and insulator (7) is fixed on steel bracket body (8).Contact rail (1) web place is provided with long trough hole, and fish plate fixed cover (2) can therefrom pass and level and smooth parallel motion in its space.Regulate contact rail (1) and the gap value that clamps fish plate (4) lower bevel by increasing or reduce fish plate fixed cover pad (3).
The installation process of contact rail on the utility model: first use fastener to pass contact rail (1), both sides are used and rely on fish plate fixed cover (2) and the isolated clamping fish plate of fish plate fixed cover pad (3) (4) clamping contact rail (1); Clamping fish plate (4) is fixed on set lagging (6) at the interval of backboard fixed cover (5) by this fastener equally in addition; Insulator (7) is fixed on to steel bracket body (8) by fastener upper, then set lagging (6) is fixed on insulator (7) by fastener.Make fish plate fixed cover (2) can contact rail (1) arrange long trough hole in can be level and smooth parallel motion, and clamping fish plate (4) the upper inclined surface clamping that contacts with contact rail (1) upper inclined surface, lower bevel leaves gap value, and this gap value can regulate by the increase and decrease of fish plate fixed cover pad (3).Finally all fastening, clamping fish plate (4) can support contact rail (1), and contact rail (1) can free horizontal slip within the scope of long trough hole.

Claims (4)
