要

在煤礦開(kāi)采過(guò)程中，瓦斯的控制及排放是關(guān)系到煤礦安全的極其重要的問(wèn)題，很多時(shí)候都需要對(duì)尚未開(kāi)采的煤礦中的瓦斯進(jìn)行鉆孔排放。鉆孔效率取決于鉆桿鉆進(jìn)的時(shí)間以及裝卸鉆桿等方面的輔助工作時(shí)間。一般鉆孔深度深達(dá)幾十米甚至上百米，而每節(jié)鉆桿的長(zhǎng)度只有0.8米，因此鉆桿在鉆進(jìn)和退出的時(shí)候分別要進(jìn)行大量的裝鉆桿和卸鉆桿的重復(fù)工作。
目前裝卸鉆桿大多采用人工操作，勞動(dòng)強(qiáng)度大、效率低。所以設(shè)計(jì)一種半自動(dòng)快速裝卸鉆桿裝置實(shí)現(xiàn)裝卸鉆桿的半自動(dòng)化，將大大縮短安裝鉆桿需要的時(shí)間，提高鉆孔效率，同時(shí)也可以減少人工裝卸鉆桿造成的安全事故。
本文介紹了一種半自動(dòng)鉆桿裝卸裝置，該裝置由鉆桿庫(kù)、鉆桿轉(zhuǎn)移裝置兩部分組成。鉆桿庫(kù)用來(lái)存放鉆桿，同時(shí)鉆桿庫(kù)上裝有棘輪定位裝置，可以實(shí)現(xiàn)鉆桿庫(kù)的轉(zhuǎn)動(dòng)并準(zhǔn)確定位以輔助鉆桿轉(zhuǎn)移裝置抓取鉆桿；鉆桿轉(zhuǎn)移裝置則將鉆桿從鉆桿庫(kù)轉(zhuǎn)移到鉆桿的安裝位置并輔助安裝。所有的控制都通過(guò)液壓控制實(shí)現(xiàn)。

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 .


Key words： semi-automatic loading and unloading drill pipe，
drill pipe warehouse，transfer device of drill pipe， hydraulic control
