Rail web rust removal sander

Abstract

The invention discloses a rail web rust removal sander. The rail web rust removal sander comprises a first abrasion wheel for sanding left side face of a rail web of a steel rail, a second abrasion wheel for sanding right side face of the rail web of the steel rail, and a main frame, wherein one end of the main frame is provided with a tail travelling frame while the other end thereof is provided with a first fixing frame and a second frame, a first work head for driving the first abrasion wheel to rotate is mounted on the first fixing frame, a second work head for driving the second abrasion wheel to rotate is mounted on the second fixing frame, the left and right sides of the tail travelling frame both are provided with travelling wheels travelling along the lower bottom surface of the rail jaw of the steel rail, two first guide wheels respectively travelling along the left side face and the right side face of the rail jaw of the steel rail are mounted on the tail travelling frame, and one end, away from the tail travelling frame, of the main frame is provided with two second guide wheels respectively travelling along the left side face and the right side face of the rail jaw. The rail web rust removal sander runs steadily, has a good sanding effect, and is simple in structure, convenient to disassemble and assemble, and convenient to generalize and use.

Description

technical field [0001] The invention relates to a grinder, in particular to a rail waist derusting grinder. Background technique [0002] Before the welding construction of long and short rails, in order to ensure that the mobile rail welding unit is fully conductive during the welding process and the aluminothermic welding avoids slag inclusions and pores during the welding process, the rail waist must be ground. Due to the construction requirements of some projects, the use of three-phase grinders requires four workers to hold one each to grind the rail waist at the same time. Practice has repeatedly proved that this method is time-consuming, labor-intensive, high in cost, and the working space is limited. It can also be damaged due to long-term operation. Therefore, the use of manual hand-held grinders for rail waist derusting is far from meeting the requirements of high efficiency, high quality, and low cost for welding operations.

Due to the construction requirements of some projects, the use of three-phase grinders requires four workers to hold one each to grind the rail waist at the same time. Practice has repeatedly proved that this method is time-consuming, labor-intensive, high in cost, and the working space is limited. can also be damaged due to prolonged operation

Therefore, the use of manual hand-held grinders for rail waist derusting is far from meeting the high efficiency, high quality, and low cost requirements of welding operations.
