A method and device for assisting manual loading and unloading of drill rods for hydraulic rock drilling rigs

Abstract

A hydraulic drilling machine drill rod manual loading / unloading assisting method and device are provided; the drilling machine is provided with a loading / unloading rack moving with the drilling machine; the loading / unloading rack can catch the drill rod in a low position, and can hang up the drill rod in a drilling machine return and ascending process, so the drill rod can be erected in and fixed by a steel retainer, then the shank of the drilling machine screws into the drill rod and the drill rod is installed; in an unloading process, the to-be-unloaded drill rod is separated from a drilling machine impact rod and an under drill rod, the drill rod bit of the to-be-unloaded drill rod is artificially pulled in a horizontal manner, the loading / unloading rack of the drilling machine moves downwards with the drilling machine, and the to-be-unloaded drill rod is slowly lowered and flatted, thus unloading the drill rod; the loading / unloading rack is provided with a round hole with a gap, the tail of the drill rod can be moved into the gap, so the drill rod can be hung on the loading / unloading rack.

Description

technical field [0001] The invention belongs to the technical field of manual loading and unloading of drill rods, and is mainly used in the application occasions of manually adding drill rods and removing drill rods during the drilling process of rock drilling rigs. Background technique [0002] A common rock drilling rig is equipped with a drill rod with a length of 3.7 meters, a diameter of 32 mm, and a weight of about 23 kg. The disadvantage of installing it is that manual straightening is easy to shake, and it is not easy to center, resulting in the failure of the installation of the drill rod, and the weight of the drill rod is heavy, and the workers are prone to hand fatigue, so it is not suitable to work in this position for a long time; it is installed with an auxiliary device And dismantling the drill rod can improve the installation accuracy, improve the construction safety of workers, and reduce the labor intensity of workers. At the same time, the increased equi...

[0002] A common rock drilling rig is equipped with a drill rod with a length of 3.7 meters, a diameter of 32 mm, and a weight of about 23 kg. The disadvantage of installing it is that manual straightening is easy to shake, and it is not easy to center, resulting in the failure of the installation of the drill rod, and the weight of the drill rod is heavy, and the workers are prone to hand fatigue, so it is not suitable to work in this position for a long time; it is installed with an auxiliary device And dismantling the drill rod can improve the installation accuracy, improve the construction safety of workers, and reduce the labor intensity of workers. At the same time, the added equipment cost is low, and the mechanical structure is simple and reliable.
