Drilling device for rail

Abstract

The invention discloses a drilling device for steel rails. The drilling device comprises a drilling mechanism for drilling the steel rails and a conveyer device for positioning the steel rails; the conveyer device is provided with 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 device, 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; a T-shaped support pad is arranged between a positioning plate and a supporting plate in each positioning mechanism, the lower end of the T-shaped support pad is arranged in a chute, and the T-shaped support pad can reciprocate along the chute; therefore, different support pads can be replaced to machine the steel rails in different models, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to a drilling device, in particular to a drilling device for a steel rail. 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 ...

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
