Multifunctional steel rail drilling machine

Abstract

The invention discloses a steel rail drilling machine, relating to the field of machinery. The steel rail drilling machine comprises a slide rail of which one end is provided with a tightening device and the other end is provided with an upper box body and a lower box body, wherein a main motor and a propulsion mechanism are arranged in the upper box body; a rotating shaft is mounted in the lower box body, and a driven chain wheel and a drill bit connector for fixing a drill bit are mounted on the rotating shaft; the main motor drives the drill bit connector to rotate; the propulsion mechanism comprises a lead screw driven by an adjustable-speed motor, a quick switch bracket is mounted on the lead screw, the slide rail is connected with the lead screw through the quick switch bracket, and a stroke adjuster is mounted on the quick switch bracket; the upper box body and the lower box body are driven by the propulsion mechanism to synchronously move along the slide rail; and the steel rail tightening device comprises a rail tightening front clamp and a rail tightening rear clamp which are used for clamping and tightening a steel rail. The steel rail drilling machine disclosed by the invention can solve the problems that the existing steel rail drilling machine is larger in volume and noise, is inconvenient for drilling steel rails in a very narrow space, and is inconvenient for drilling in sections and intervals without dynamic electricity.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a drilling machine used for drilling railway rails in a narrow space or in the field far away from mains electricity. Background technique [0002] In the construction of modern railways, rail drilling is an indispensable project for railway lines and railway signal construction and has a large workload. In the maintenance and construction of railway engineering, electrical services and other departments, the drilling of steel rails is often involved, especially It is the drilling operation in areas and intervals without power and electricity, and sometimes it is necessary to drill holes between rails with a particularly narrow space. Most of the existing drilling machines are electric drilling machines, gasoline drilling machines, etc., which are noisy and bulky, and are not easy to carry and power supply when working in the field. Although there are also manual ra...
