A rail drilling machine based on railway engineering

Abstract

The invention discloses a rail drilling machine based on railway engineering, which effectively solves the problem that the existing rail drilling machine can only feed in one direction and has poor adaptability when drilling. The meshing transmission between the ring gears controls the amount of feed and retraction of the drill bit during drilling, so that the feed action of the drill combines the advantages of manual drilling and mechanical drilling, which not only ensures the uniformity of drilling Drilling avoids cutting and blocking drilling, reduces the wear of the drill bit to the greatest extent, and prolongs the life of the drill bit. The positioning process and drilling process of the device of the present invention are all carried out automatically, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of railway engineering, in particular to a rail drilling machine based on railway engineering. Background technique [0002] Rail drilling machine refers to a type of drilling machine for on-site drilling of rails. It is one of the small machines commonly used in railway emergency maintenance operations. During the drilling process of rails, the drill bit must be pushed out frequently to eliminate cutting and cooling. To prevent cutting blockage or overheating of the drill bit or even breakage, and to make the drill bit evenly drilled, the existing rail drilling machine has two methods of manual drilling and mechanical drilling to control the feed drilling of the drilling machine. Move the joystick / hand handle, through the transmission system of worm gear, rack and pinion, drive the drill bit to feed or retract, and complete the rail drilling operation.

[0002] Rail drilling machine refers to a type of drilling machine for on-site drilling of rails. It is one of the small machines commonly used in railway emergency maintenance operations. During the drilling process of rails, the drill bit must be pushed out frequently to eliminate cutting and cooling. To prevent cutting blockage or overheating of the drill bit or even breakage, and to make the drill bit evenly drilled, the existing rail drilling machine has two methods of manual drilling and mechanical drilling to control the feed drilling of the drilling machine. Move the joystick / hand handle, through the transmission system of worm gear, rack and pinion, drive the drill bit to feed or retract, and complete the rail drilling operation. Drilling in this way can ensure real-time feed and retract. The situation of cutting blockage is avoided, but workers often cannot maintain uniform force on the joystick / hand handle, and thus cannot ensure the uniform drilling of the drill bit. When the force is too large, the drilling amount will increase, wear or even damage the drill bit. If it is too small, the drilling rate will be reduced, the working time will be prolonged, and the workload of the workers will be increased. Manual feeding for a long time will also make the workers feel tired. At the same time, manual drilling generally requires two people to work together, that is, one person controls the drilling machine. Feed rate, another person cooperates with water supply cooling, which increases the labor cost; the existing mechanical drilling device generally uses rack and pinion drive / screw drive to drive the drill to feed the hole, but these two feed methods are controlled The drill bit feeds in the same direction for a long time, that is, the whole drilling process is only the feeding process. Although the mechanical drilling ensures the uniform drilling of the drill bit, the tool cannot be retracted during the drilling process, which can easily cause wear and breakage of the drill bit. , which greatly reduces the service life of the drill bit

[0003] Drilling should be slow at the beginning of drilling to prevent the drill bit from cracking, and when the hole is about to be drilled through, the amount of feed should also be reduced to avoid the vibration of the drill bit at the moment of drilling through, which will cause the phenomenon of "biting the knife" and make the exit irregular. , increase the workload of repairing holes, mechanical drilling cannot meet the above requirements, and manual drilling is time-consuming and laborious
