Problems solved by technology
[0003] At present, it is necessary to drill holes on the rail after production. Since there is no special tooling, the conventional method is to lift the rail with a weight of tens of tons by a crane and place it on a processing platform. After fixing, manually use a drilling rig Drilling holes one by one, because each rail is long, it takes a long time for the master worker to finish drilling a rail, so the production efficiency is greatly reduced, and the labor intensity of the workers is high

Embodiment Construction
[0019] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is based on the technical solution of the present invention, and provides detailed implementation methods and specific operating procedures, but the scope of protection of the present invention is not limited to the following embodiments. .
[0020] As shown in the figure, a tooling for rail drilling includes a traveling mechanism 1 with a support plate 101. The traveling mechanism moves under the drive of the drive motor. In actual working conditions, the traveling wheels of the traveling mechanism 1 can be set on the guide rail. On the top, the traveling mechanism moves along the direction of the guide rail during the moving process, the orientation is good, and the position deviation of the drill hole will not be affected. The positioning mechanism 3 for positioning and placing the rail on both sides of the tightening mechanism;

The invention discloses a fixture for drilling steel rails. The fixture comprises a travelling mechanism with a supporting flat plate; the travelling mechanism is driven to move by a driving motor; the upper end face of the supporting flat plate is fixedly provided with a steel rail pressing mechanism and positioning mechanisms which are symmetrically arranged on two sides of the steel rail pressing mechanism and are used for positioning and placing the steel rails. According to the fixture, the steel rails are arranged on a travelling trolley provided with the positioning mechanisms and the pressing mechanism, the positioning and pressing efficiency is high, the heavy-weight steel rails can be conveniently moved, and the production efficiency is greatly improved by drilling the steel rails during movement of the travelling trolley; as two groups of steel rails can be drilled when the travelling trolley moves each time, and the production efficiency is improved by more than 50 percent.
Description
technical field [0001] The invention relates to a rail drilling equipment, in particular to a tool for rail drilling. Background technique [0002] In accordance with the decision-making deployment of the State Council executive meeting, China Railway Corporation has increased the goal of this year's railway construction on the basis of comprehensive consideration of economic and social development needs, railway transportation needs, and railway construction capital guarantee capabilities. First, the number of newly started projects has increased from 44 to 48; second, the national railway fixed asset investment has increased from 700 billion yuan to 720 billion yuan; third, the mileage of new lines has increased from 6,600 kilometers to more than 7,000 kilometers. With the gradual expansion of the scale of railway construction, the demand for rails is also increasing day by day, and the supporting production and processing enterprises are gradually taking how to improve th...
