Problems solved by technology

[0002] At present, the steel rails are usually processed and bent in the factory. At the construction site, under special construction conditions, some special parts of the steel rails need to be bent according to actual needs. However, because the material of the steel rails is manganese steel, the yield strength is large, and Due to the limitation of the space environment on the construction site, it takes a lot of manpower and material resources to bend, and the cycle is long, which often affects the progress of the next process, increases the labor intensity of the construction personnel, and also has potential safety hazards

Embodiment Construction

[0024] In the track construction project of the feeding inclined bridge in an ironworks, it is necessary to determine the curvature of the track according to the actual path of the feeding trolley and the installation of the inclined bridge on site. The main engineering quantities are four rails in total, and the four rails are all constructed using the simple hot-bending method of steel rails proposed by the present invention.

[0025] The operation steps of the simple and easy thermal bending method of the rail are as follows:

[0026] 1) Set the bottom plate:

[0027] Place a steel bottom plate 2 on the construction site, and use a level to level the bottom plate 2. The unevenness of the bottom plate 2 is: no more than 1mm per meter. According to the requirements of the bending of rail 1 (that is, the track) or the size of the drawing, according to the bending arc of rail 1, the arc section of rail 1 is divided into three sections from left to right on the bottom plate 2 (...

Abstract

The invention relates to a simple hot bending method for a steel rail, and belongs to a method for steel rail bending in a construction site. The simple hot bending method is characterized by adoptingjacks, a heating device and a steel rail positioning assembly device for hot bending of the steel rail. The hot bending process includes the steps that 1), a bottom plate is arranged; 2), the positioning assembly device and machines and tools for hot bending of the steel rail are prepared; 3) the steel rail is arranged; 4), hot bending is conducted on the steel rail. All groups of positioning blocks and inclined wooden wedges are uniformly and equidistantly distributed on the front and rear sides of the left straight-line section of the steel rail and installed in a staggered manner, the steel rail is fixed, a jack I, a jack II, a jack III and a jack IV are arranged corresponding to the arc segments of the steel rail, the heating device conducts continuous segmented high-temperature heating on the arc segments of the steel rail, the jack I, the jack II, the jack III and the jack IV are driven to jack up and press the steel rail in the high-temperature heating process, the steel rail is formed into shape by hot bending, the operation is convenient, the use is safe and reliable, and the construction quality and construction efficiency are improved.

Description

technical field [0001] The invention belongs to a steel rail bending method at a building construction site, in particular to a method for hot-simmering steel rail bending. Background technique [0002] At present, the steel rails are usually processed and bent in the factory. At the construction site, under special construction conditions, some special parts of the steel rails need to be bent according to actual needs. However, because the material of the steel rails is manganese steel, the yield strength is large, and Due to the limitation of the space environment on the construction site, it takes a lot of manpower and material resources to bend, and the cycle is long, which often affects the progress of the next process, increases the labor intensity of the construction personnel, and poses safety hazards. Contents of the invention [0003] The purpose of the present invention is to propose a simple hot-bending method for rails, which is not only simple in operation, c...
