Embodiment Construction

[0034] Attached below Figure 1-12 Specific examples of the present invention are described.

[0035] (Such as figure 1 As shown) the rail straightening and adjusting preheating device with asymmetric cross section includes a rail preheating device 1 and rail straightening and adjusting equipment 7 .

[0036] The rail preheating device 1 is used for heating the rail, and the rail straightening equipment 7 is used for straightening after the rail is preheated. When the preheating temperature of the rail on the rail preheating device 1 reaches the required value, after the rail is hoisted from the rail preheating device 1 to the rail straightening equipment 7, the preheated rail is carried out on the rail straightening equipment 7 Adjustment operation.

[0037] (combined with figure 2 ) The rail preheating device 1 is installed on the top of the lifting platform 2 that lifts in the Z direction. The lifting platform 2 adjusts the Z-direction height of the lifting platform a...

Abstract

The invention provides an asymmetric section steel rail straightening and preheating device which comprises a steel rail preheating device. The steel rail preheating device is mounted at the top of a lifting platform. The lifting platform does translation along X-direction trolley rails. The steel rail preheating device comprises a steel rail preheating tool. The steel rail preheating tool is of an I-shaped structure in bilateral symmetry. Steel rail outline lateral auxiliary positioning devices are detachably mounted on the left side and the right side of the steel rail preheating tool. By means of the asymmetric section steel rail straightening and preheating device, the problem about rapid local preheating of an asymmetric section steel rail is solved, the preheating process progress is accelerated, the preheating operation difficulty is reduced, use is convenient, the number of times of clamping is reduced, the machining efficiency is improved, and the machining quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rail straightening and manufacturing, and in particular relates to a rail straightening and preheating device with an asymmetric section. Background technique [0002] Steel rails are an important part of railway rails, and the stress conditions are very complicated when they are used on the line. In order to prolong the service life of high-speed turnouts and the demand for operational safety, according to the force characteristics of wheel loads, rail profiles with different cross-sectional shapes are designed at different rail positions to resist the force acting on the rails and make railway transportation smooth Be strong and keep the rails for the life they were designed for. [0003] Among them, the most widely used part of the high-speed railway turnout switch is the special cross-section rail (60AT1, 60AT2), and the most widely used movable frog part is the special cross-section rail (60TY1 rail...
