Abstract
The utility model discloses a safe and anti-theft rail fixing apparatus which comprises a steel rail and clamping plates fixed on both sides of the steel rail through screws and nuts. The safe and anti-theft rail fixing apparatus comprises two clamps which are arched and are identical in structure. The central portion of the inner arc surface of each clamp is provided with a U-shaped groove matching with the bottom of the steel rail. The upper portions of the two clamps clamp the lower portions of the clamping plates respectively. The two clamps are fixed on both sides of the steel rail through a bolt and a nut with an antitheft aperture. A pinhole corresponding to the antitheft aperture is arranged on the bolt, and the antitheft aperture is provided with antitheft threads. A pinhole is arranged on the bottom of the antitheft threads and provided with an alloy block with low melting point. The safe and anti-theft rail fixing apparatus is reasonable in structure, and excellent in antitheft effect, and is safe and reliable.
Description
Technical field
The utility model relates to a kind of railroad track, particularly a kind of railroad track rail clamping device of safe antitheft.
Background technology
railway is the track of the vehicles such as train, subway, and railway transportation is a kind of land transportation mode, walks on two parallel rails with the locomotive traction train.Track is the engineering structures of a globality as the important component part of rail track, and it is by rail, sleeper, connecting piece, railway roadbed, and critical pieces such as anti-creep equipment and track switch are formed, and track is made up of two parallel rail usually.Rail fixedly is placed on the sleeper, is railway roadbed under the sleeper, and union piece is playing a connection effect between rail and the rail and between rail and the sleeper.Rail carbon steel commonly used or medium managese steel manufacturing; Its section is I-shaped; In order to bear the wheel load of rolling stock; And the load that bears passed to sleeper, simultaneously for the rolling of wheel provides continuous, smooth-going surface and the operation of guiding wheel, I-shaped rail is mainly by the flange of rail of the rail head on top and bottom and be connected rail head and the web of the rail of the flange of rail is formed.Existing connecting piece is disassembled easily, promptly gets final product with general spanner, causes relevant component stolen, very easily causes train to produce derailment accident, causes bigger loss.Therefore,, must the dispatch personnel patrol safeguard, increased human and material resources in order to safeguard the safe operation of railroad train
Summary of the invention
It is a kind of rational in infrastructure, safe and reliable that the purpose of the utility model just is to provide, the rail track rail clamping device of the safe antitheft of good anti-theft effect.
To achieve these goals, the technical scheme of the utility model employing is such: the railroad track rail clamping device of the safe antitheft of the utility model comprises rail and clamping plate; Clamping plate are fixed on the rail left and right sides through screw and nut, also comprise two clamps, and two clamp structures are identical and be arcuate structure; The intrados of two clamps middle part is corresponding respectively to be provided with the U-lag that the flange of rail with rail is complementary; The top of two clamps is the bottom of clamping two clamping plate respectively, and in the rail both sides, nut is provided with the hole of guarding against theft to two clamps through a bolt and fixed by nut; Have the pin-and-hole corresponding on the bolt with the hole of guarding against theft; Antitheft is provided with the antitheft threaded in the hole, and the bottom of antitheft threaded is arranged in the pin-and-hole, is provided with low fused gold bullion in the antitheft hole.
As preferably, said nut is concordant with the bottom surface of screw, on the fair face of nut and screw through the screw thread seam welding.
As preferably, the both ends of said screw are provided with rubber ring.
Compared with prior art, the advantage of the utility model is: the utility model is rational in infrastructure, and is safe and reliable, and screw is through screw thread seam welding nut; Theftproof is strong, is difficult for being removed, and also is provided with clamp, clamp through bolt and fixed by nut in the rail both sides; Have the antitheft hole on the nut, have corresponding pin-and-hole on the bolt, the threaded of will guarding against theft screws in the antitheft hole, the low-melting alloy piece is pressed into the remainder of sealing of hole again; Polish exposed parts, disguised strong, be difficult for coming to light, also be difficult for cracking even come to light; Can prevent effectively that the relevant component of railway are stolen, guarantee that train normally moves, not need the special messenger to go on patrol maintenance, save human and material resources; Said screw two ends are provided with rubber ring, are convenient to adjust the slit of rail, and can avoid between screw and the nut friction and cause crator to come off.The utility model has fundamentally prevented the derail that takes place because of clamping plate are stolen even the hidden danger of great railway accident has taken place.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, rail; 2, clamping plate; 3, screw; 4, clamp; 5, bolt; 6, antitheft threaded; 7, rubber ring.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1 and Fig. 2, the railroad track rail clamping device of the safe antitheft of the utility model comprises rail 1 and clamping plate 2; Clamping plate 2 are fixed on rail 1 left and right sides through screw 3 and nut, comprise that also two clamps, 4, two clamps, 4 structures are identical and are arcuate structure; The intrados of two clamps 4 middle part is corresponding respectively to be provided with the U-lag that the flange of rail with rail 1 is complementary, and the top of two clamps 4 is the bottom of clamping two clamping plate 2 respectively, two clamps 4 through a bolt 5 and fixed by nut in rail 1 both sides; Nut is provided with the antitheft hole; Have the pin-and-hole corresponding with the hole of guarding against theft on the bolt 5, be provided with antitheft threaded 6 in the antitheft hole, the bottom of antitheft threaded 6 is arranged in the pin-and-hole; Be provided with low fused gold bullion in the antitheft hole; Said nut is concordant with the bottom surface of screw 3, and through the screw thread seam welding, the both ends of said screw 3 are provided with rubber ring 7 on the fair face of nut and screw 3.
During installation, behind 1 pair of good position of two rails, install clamping plate 2 through screw 3 in the both sides, joint; Two clamps 4 are placed on rail 1 joint both sides respectively behind the flange of rail location through rail 1, and two clamps 4 are fixed on the rail 1 with nut through a bolt 5, have the antitheft hole on the nut; Have corresponding pin-and-hole on the bolt 5; The threaded 6 of will guarding against theft screws in the antitheft hole, the low-melting alloy piece is pressed into the remainder of sealing of hole again, promptly accomplishes and installs.
