Steel rail drilling machine capable of realizing three-dimensional, rapid and accurate positioning

Abstract

The invention discloses a steel rail drilling machine capable of realizing three-dimensional, rapid and accurate positioning. Bow-shaped fixing brackets are formed by curves of the waist of a steel rail and used for avoiding the deformed part of the head of the steel rail, so that curved surfaces of the waist of the steel rail are closely meshed with curved surfaces of the bow-shaped fixing brackets, lifting locking devices are used for fixing the bow-shaped brackets at the waist of the steel rail, and stable supports for a drilling device are formed. The bow-shaped brackets are connected with transverse moving sliding bars of a motor, and rail bottom hooks for hooking the rail bottom are arranged on the bow-shaped brackets; the motor is fixed in an outer profiling ring, upper and lower semi-circular sliding grooves and an inner worm moving gear ring are arranged on the outer profiling ring, the outer profiling ring is connected with upper and lower sliding supports, a worm steering box is arranged on the lower sliding support, positioning holes are formed in the transverse moving sliding bars, a positioning pin is arranged on the upper sliding support, when the upper sliding support moves to the positioning holes of the transverse moving sliding bars, the positioning pin is inserted into the positioning holes under the action of an elastic device, and rapid, accurate and automatic positioning is realized. The machine is high in drilling accuracy and widely applicable to drilling of new and old steel rails.

Description

technical field [0001] The invention relates to a three-dimensional fast and precise positioning rail drilling machine. In particular, it is an accurate drilling device that does not need to manually measure the drilling positioning size, can be installed in the left and right directions, and can be disassembled and moved quickly, avoiding the easily deformed and worn parts of the rail head, and realizing the rapid positioning of the rail. Background technique [0002] In the current stage of railway construction, there is a kind of connection between rails that is carried out in the form of fishtail splints. This connection must be drilled on the rail waist of the rails. This kind of on-site construction work is usually It is realized in the form of electric drilling machine and internal combustion drilling machine; no matter what kind of drilling equipment is used, the positioning of the drilling machine must be carried out to ensure that the size of the hole on the rail a...

AI Technical Summary

Problems solved by technology

There are human vision errors, template movement errors, and rail deformation errors when using templates for positioning; the top of the rails will be deformed after a period of use, and the greater the deformation, the less accurate the drilling positioning will be; when using the rail bottom for positioning, Although there is basically no deformation at the bottom of the rail, the positioning is troublesome. One is to remove the ballast at the bottom of the rail, and the other is to remove a certain depth. When there are obstacles on the bottom of the rail, it is even more troublesome. Compare three times, move three times, and pick up the ballast three times. Errors are inevitable and the efficiency is not high.
