Embodiment 1

[0022] Embodiment one: if Figure 5 and Figure 6 As shown, the rail clamping device 1 is mainly composed of a clamp 11, a connecting rod 12, a clamping cylinder support 13, a clamping cylinder 14, a rotating shaft 15, a clamp support 16 and a clamping jaw 17. The upper end of the clamp 1 is flexibly connected with the clamping oil cylinder support 13 through the connecting rod 12, the clamping oil cylinder support 13 is fixed on the cylinder block at the upper end of the clamping oil cylinder 14, and the piston rod at the lower end of the clamping oil cylinder 14 is connected with the clamping support. The seat 16 is connected, and the two rotating shafts 15 are respectively installed on both sides of the clamp support 16 according to the length direction parallel to the rail. The lower end of the clamping jaw 17 is connected to form a lever structure with the rotating shaft 15 as a fulcrum, the upper end of the clamping clamp 11 as a force application point, and the lower e...

Embodiment 2

[0026] Embodiment two: if Figure 9 As shown, the main difference between this embodiment and Embodiment 1 is that a different type of rail clamping device 1 is used. This rail clamping device 1 only has one rotating shaft 15, so the horizontal guide rail 21 at one end of the structural outer frame 2 has only one One section, of course, the cross-sectional width at both ends of the rotating shaft 15 is also smaller than the length of the horizontal guide rail 21, so that under the action of the alignment force applying device 5, the rail clamping device 1 can reciprocate along the horizontal guide rail 21 relative to the structural outer frame 2. Because in each embodiment of the present invention, the main innovation point of the present invention is not on the specific structure of rail clamping device 1, so the specific structure of rail clamping device 1 in embodiment one and embodiment two is no longer exhausted Syria.

Embodiment 3

[0027] Embodiment three: as Figure 10 As shown, the main difference between this embodiment and Embodiment 1 is that the two sections of horizontal guide rails 21 corresponding to the two rotating shafts 15 are opened into a horizontal track, which is easier to realize in the mechanical processing of the structural frame 2, and the rail clamping device 1 is also more convenient to install, and the rail clamping device 1 is also placed on the horizontal guide rail 21 of the structural outer frame 2 through the rotating shaft 15. Other structures in this embodiment are basically the same as those in Embodiment 1, so they are not repeated here.

Abstract

The invention relates to a steel rail butt welding machine aligned according to steel rail working line by clamping, comprising two steel rail clamping devices, each steel rail clamping device is correspondingly arranged in a structural frame, the two end surfaces in the structural frame are provided with horizontal guide rails, the steel rail clamping devices are arranged on the horizontal guiderails of the structural frame and can move in a reciprocating way along the corresponding structural frames of the horizontal guide rails under the action of external force; the lower parts of the two end surfaces of the structural frame can contain notches of the steel rails, and the two side surfaces and the top surface of the notch are aligned; the two structural frames are connected with a force application guiding shaft by penetrating through guiding shafts at the end surfaces, and one end of the force application guiding shaft is connected with an upsetting force application hydro-cylinder and can drives one structural frame to move axially in a reciprocating way along the force application guiding shaft under the action of the hydro-cylinder. The steel rail butt welding machine hasthe beneficial effects that: the difficult problem of field welding technology of the steel pipe that the alignment is carried out according to the steel rail working line when the steel rail is butt-welded is overcome with a simple method, thereby meeting the requirements of high-standard and seamless-track site operation.

Description

technical field [0001] The invention belongs to the technical field of on-site rail welding equipment for railway seamless lines, and in particular relates to equipment for butt welding of rails. Background technique [0002] In the rail laying and rail replacement construction of seamless lines, on-site welding of the rails is required. The welding methods currently used are mainly butt welding, namely flash welding and pressure welding. In the rail butt welding process, whether flash welding or gas pressure welding is used, the two ends of the joint to be welded need to be clamped and aligned, and then heated and upset. Such as figure 1 and figure 2 As shown, since the wheel rim 8 of railway locomotives and vehicles is unilateral and located on the inner side of the track, the size and smoothness of the inner surface of the rail head 9, 9' are related to the operation of the railway locomotive, and are generally called rails. Working sides 91, 91'. Since the rails 9 ...
