要
在煤矿开采过程中，瓦斯的控制及排放是关系到煤矿安全的极其重要的问题，很多时候都需要对尚未开采的煤矿中的瓦斯进行钻孔排放。钻孔效率取决于钻杆钻进的时间以及装卸钻杆等方面的辅助工作时间。一般钻孔深度深达几十米甚至上百米，而每节钻杆的长度只有0.8米，因此钻杆在钻进和退出的时候分别要进行大量的装钻杆和卸钻杆的重复工作。
目前装卸钻杆大多采用人工操作，劳动强度大、效率低。所以设计一种半自动快速装卸钻杆装置实现装卸钻杆的半自动化，将大大缩短安装钻杆需要的时间，提高钻孔效率，同时也可以减少人工装卸钻杆造成的安全事故。
本文介绍了一种半自动钻杆装卸装置，该装置由钻杆库、钻杆转移装置两部分组成。钻杆库用来存放钻杆，同时钻杆库上装有棘轮定位装置，可以实现钻杆库的转动并准确定位以辅助钻杆转移装置抓取钻杆；钻杆转移装置则将钻杆从钻杆库转移到钻杆的安装位置并辅助安装。所有的控制都通过液压控制实现。

ABSTRACT
In the course of coal mining, gas control and emissions which are related to mine safety is extremely important issues, and it is usually need to let the gas out of coal mine which has not been mining by drilling.
Drilling efficiency depends on the drilling time of drill pipe, as well as assistant working hours of loading and unloading drill pipe. General drilling depth is tens of meters or even hundreds meters, whereas the length of each drill pipe is only 0.8 meters, so a lot repeat works of loading and unloading drill pipe must be done when the drill pipe infix and exit.
Most of the current work of loading and unloading drill pipe is manual, labor-intensive and low efficiency. Therefore, the design of a semi-automatic loading and unloading drill pipe device to achieve semi-automatic will greatly shorten the time needed to the installation of drill pipe and improve the efficiency of drilling, at the same time ,it can also reduce the security accident caused by manual handling of the drill pipe.
In this paper, a semi-automatic loading and unloading devices of drill pipe is introduced which is composed of the drill pipe warehouse ane ane drill pipe transfer device. The drill pipe warehouse is used to store the drill pipe, and the drill pipe warehouse is equipped with ratchet positioning devices, so the drill pipe warehouse can rotate and go to the accurate positioning to support the transfer equipment to crawl drill pipe; So the transfer equipment can transferre drill pipe from the drill pipe warehouse to the installation place of drill pipe and assist to installation. All are controlled by hydraulic control .
