Abstract
The utility model relates to a rail clamping device, which comprises a left clamp, a right clamp and fishtail plates. The rail clamping device is in a split structure, the structures of the two clamps are the same arc structures, corresponding U-shaped grooves are respectively arranged below inner arc surfaces of the two clamps, and the two clamps are connected into a whole by the aid of a bolt; the fishtail plates are positioned between the two clamps, in other word, the two fishtail plates are respectively mounted on two sides of the positions of two steel rail joints; and the two clamps clamp the fishtail plates on two sides of the positions of the two steel rail joints to complete the clamping process. The rail clamping device has no spatial limitation when in installation, omits the step of penetrating the rail clamping device into a rail bottom, reduces the loosening effect of vibration of a train on the rail clamping device by particularly adding an anti-loosening structure of a fastening bolt, reduces spare part storage quantity and represents universality and interchangeability of spare parts with the standardized and serialized production. Additionally, although being designed for railway construction, the rail clamping device completely meets the requirements of being used as an emergency device and a steel rail welding seam protection device during technical rail interruption in railway engineering.
Description
Technical field
The utility model relates to a kind of rail clamping device.
Background technology
Along with China railways speed raising and great-leap-forward development, newly-built Line for Passenger Transportation all adopts gapless track.Lay a railway track after unit broadcasted the 500m rail when long rail string, the unit of laying a railway track continues to move ahead needs rail joint to connect temporarily.If adopt traditional rail connection method, need adopt clamping plate and bolt clip consolidation now to connect rail at end of rail auger shell keyhole, the method for attachment of this destruction rail is unallowed on gapless track.Simultaneously, now the rail clamping device that uses all is the monolithic rail clamping device, and on-the-spot simple processing and fabricating forms, and makes coarsely, and complexity is installed, and limited by the local space of applying working condition, and rail clamping device clamps rail after need being interspersed in the flange of rail again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of rational in infrastructure, easy to carry, that install simply, need on rail, not hole, safe and reliable, as to reach the interim split-type structural that connects of rail in gapless track work progress rail clamping device,
The technical solution of the utility model: a kind of rail clamping device, it is characterized in that this rail clamping device comprises retained part and additional lock plate portion, its retained part comprises left clamp, right clamp and bolt, left side clamp is identical with right clamp structure, promptly two clamps are arcuate structure, the intrados of two clamps below is corresponding respectively to be provided with a U-lag that is complementary with rail flange of rail thickness, left side clamp is connected one with right clamp by bolt, described additional lock board is divided into two splice bars that place between two clamps, promptly place two splice bars between two clamps to be installed in both sides, two rails joint respectively, the splice bar of both sides, two clamp clamping two rails joints.This rail clamping device is designed to split-type structural.
The utility model compared with prior art, rail clamping device is a left and right sides clamp split-type structural, and is rational in infrastructure simple, only needs a fastening pair of bolts can finish assembling process.Need not spatial constraints during installation, need not on rail, to hole, save rail clamping device and be interspersed in flange of rail step.Increased the anti-loose structure of fastening bolt especially, reduced the relexation of train vibration rail clamping device.Standardization of this rail clamping device and producing in serial form reduce the spare part amount of having, and have embodied the versatility and the interchangeability of spare part.Though this rail clamping device is to design during for construction of railways, when it satisfies the railway technology fully and interrupts rail as first aid device and steel rail welding line protective device.During installation, rail is harmless, reaches the interim purpose of connecting of rail in the gapless track work progress.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the utility model left side TV structure schematic diagram;
Among the figure, 1-left side clamp, the right clamp of 2-, 3-bolt, 4-splice bar, 5-rail.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of rail clamping device is a split-type structural, comprise retained part and additional lock plate portion, this retained part comprises left clamp 1, right clamp 2 and pair of bolts 3, left side clamp is identical with right clamp structure, and promptly two clamps are arcuate structure, and the intrados of two clamps below is corresponding respectively to be provided with a U-lag that is complementary with rail 5 flange of rail thickness, U-lag is used for fixing rail 5 flanges of rail, also plays the role of positioning during installation; Its left clamp 1 is connected one with right clamp 2 by bolt 3, and two clamps adopt cast member.Described additional lock board is divided into two splice bars 4 that place between two clamps, promptly places two splice bars 4 between two clamps to be installed in both sides, two rails 5 joint respectively, the splice bar 4 of both sides, clamping (withstanding) two rails 5 joint, two clamps top.
Installation process of the present utility model: one, behind 5 pairs of good positions of two rails, splice bar 4 is installed in the both sides, joint; Two, left clamp 1 and right clamp 2 are placed on the rail joint both sides respectively by rail 5 flanges of rail location (rail 5 flanges of rail place in the U-lag); Three, two bolts 3 are penetrated left clamp 1 and right clamp 2; Four, tighten two bolts 3 and finish installation.
