Embodiment 1

[0036] as attached figure 1 to attach Figure 6 As shown, a kind of embodiment of the railway fast fixing device 1 based on the method of the present invention is used to realize the fast fixing of the sleeper 2 and the rail 3, specifically comprising:

[0037] It is composed of nut assembly one 11 and nut assembly two 12, and has a split nut with threaded hole 16 inside. The fixed end of nut assembly one 11 is hinged with the fixed end of nut assembly two 12 through rotating shaft one 13. Nut assembly one 11 and nut assembly Two 12 can perform opening and closing movement around the rotating shaft one 13;

[0038] Connected to the clamp wrench 14 between the movable end of the nut assembly one 11 and the movable end of the nut assembly two 12, the clamp spanner 14 is used to realize the locking between the nut assembly one 11 and the nut assembly two 12;

[0039] The rail pressure plate 10 arranged at the lower part of the split nut, the spike 4 on the sleeper 2 passes thro...

Embodiment 2

[0048] An embodiment of a fast fixing method for railways based on the above-mentioned device, specifically comprising the following steps:

[0049] S101) Insert the spike 4 on the sleeper 2 into the through hole 24 of the rail clamp 10, and fix one end of the rail clamp 10 on the upper surface of the rail bottom of the rail 3; as a typical embodiment of the present invention, further insert One end of the rail pressure plate 10 along the length direction of the sleeper 2 is set as a wedge-shaped part 25, and the rail 3 is fixed under the slope of the wedge-shaped part 25;

[0050] S102) Toggle the card wrench 14, and open the nut assembly 1 11 and the nut assembly 2 12 with the rotating shaft 13 as the axis;

[0051] S103) Set the first nut assembly 11 and the second nut assembly 12 on the spike 4, and rotate the split nut so that the threaded hole 16 of the split nut matches the external thread of the spike 4;

[0052] S104) Rotate the card wrench 14, lock the nut assembly ...

Embodiment 3

[0060] In the actual use process, there may be extreme cases of distortion and deformation of the spike 4 (especially for the transformation of some old lines), at this time, if the split nut assembly with the full thread structure described in Embodiment 1 is used It is impossible to realize the closing and locking of the quick fixing device 1 for railways. In order to solve this problem, the attached Figure 7 And attached Figure 8 As shown, on the basis of Embodiment 1, the surface of the threaded hole 16 is further along the axial direction (as attached Figure 8 The direction shown in C) provides a notch groove 28 to adapt to the distortion and deformation of the road stud 4. When the spike 4 is distorted and deformed, align the distorted portion of the spike 4 with the notch 28 of the threaded hole 16, so that the split nut can be smoothly closed and locked.

[0061] As a preferred specific embodiment of the present invention, a half threaded hole 16 is respectively ...

Abstract

The invention discloses a fast fixation method for railways. Fixation of railway sleepers and steel rails is achieved through two fast fixation devices for the railways. Each fast fixation device forthe railways is composed of a first nut assembly, a second nut assembly, a clamping wrench and a steel rail pressing plate, wherein each first nut assembly and the corresponding second nut assembly form an openable nut in which a threaded hole is formed. The method includes the following steps of inserting spikes on the railway sleepers into through holes in the steel rail pressing plates and making one end of each steel rail pressing plate fixed to the upper surface of the bottom of the corresponding steel rail; toggling the clamping wrenches and opening each first nut assembly and each second nut assembly with a first rotating shaft as an axial center; sleeving the spikes with the first nut assembles and the second nut assemblies, and rotating the openable nuts to make the threaded holesof the openable nuts matched with outer threads of the spikes; rotating the clamping wrenches and locking the first nut assemblies and the second nut assemblies to complete fast fixation of the railway sleepers and steel rails. The technical problems that traditional fixation modes for the steel rails and the railway sleepers are low in operation efficiency, waste operation time and have a strongimpact on the operation progress can be solved.

Description

technical field [0001] The invention relates to the field of railway engineering construction, in particular to a method for temporarily and rapidly fixing sleepers and rails, which is applied to railway construction. Background technique [0002] During the construction process of railway track laying, track changing, and sleeper changing, it is often necessary to temporarily fix sleepers and rails. For example, during some sleeper replacement operations, the ballast will be excavated first. At this time, the sleeper cannot be in contact with the ballast bed, so it is necessary to temporarily fix the sleeper on the rail (at this time, the sleeper is in a suspended and fixed state) to ensure the safety of subsequent construction. went well. The existing construction operation mode is to wait for the workers to install the rail fasteners one by one on the sleeper, and then carry out follow-up construction after completing the fixing of the sleeper and the rail. Under the pr...
