摘 要
1963年，設(shè)計(jì)民微型Hydrack鉆機(jī)。這是一種非常輕而短的鉆機(jī)，其行程為851mm。采用三速齒輪箱，其最大轉(zhuǎn)矩為691Nm，有效鉆孔推力為2145公斤。設(shè)計(jì)鉆桿較小，直徑為41.3mm，長為762mm，也帶錐形螺紋接頭，稱為ET/A型鉆桿。ET/A型和最初的ET/N型鉆桿是抽放瓦斯的兩種標(biāo)準(zhǔn)鉆孔設(shè)備，現(xiàn)已包括在英國煤炭部第613/1974號樣本中。
鉆機(jī)——有一個(gè)帶滑板的機(jī)架，由滑板支撐。鉆頭安裝在滑座上，由液壓馬達(dá)、變速齒輪箱和推力套以及供水旋轉(zhuǎn)接頭組成。在機(jī)架內(nèi)滑座下是液壓缸。機(jī)架上鉆孔末端的導(dǎo)向夾持器用來固定和支持鉆桿。
Hydrack鉆機(jī)是由由組標(biāo)準(zhǔn)件裝置組成；
動(dòng)力設(shè)備——這是一個(gè)裝有液壓油的油箱，下面有滑橇，便于運(yùn)輸。一臺電動(dòng)機(jī)和液壓泵及其它輔助設(shè)備，如回油過濾器、安全閥、加油泵、油箱通氣管以及濕度安全開關(guān)都安裝在油箱上面。
控制盤——為四個(gè)裝置中最小的。包含有鉆孔功能的控制閥，指示轉(zhuǎn)矩的壓力計(jì)以及鉆頭上的鉆進(jìn)壓力。
裝配式機(jī)架——當(dāng)準(zhǔn)備鉆孔時(shí)，機(jī)架支撐著鉆機(jī)。機(jī)架形式多種以適應(yīng)不同鉆孔地形變化，有H型機(jī)架、A型機(jī)架和單支柱支座。后兩項(xiàng)是根據(jù)鉆機(jī)使用者提出來的要求設(shè)計(jì)的。
液壓油通過撓性液壓軟管從動(dòng)力裝置站輸送到控制盤，然后進(jìn)入鉆機(jī)。軟管一般長4m，能適應(yīng)各種裝置的定位。

ABSTRACT
Hydrack gas drilling rig is the first for the electro-hydraulic drilling rig, the rig before most of the air-powered. Drill pipe and bit by a hydraulic motor through the rotating six-speed gear box; to be thrust into power and the trip from 815 mm to achieve the hydraulic cylinders, with rack and pinion system to process will be carried out twice. About the most torque 949 Nm, a way to about 1702 mm bit on the effective thrust of about 2,794 kg. Diameter drill pipe design for the 60.3 mm, for the 1524 mm long with a cone-shaped male connector, commonly known as EF / N-type drill pipe.
1963, the design of the micro-Hydrack rig. This is a very short period of Qinger drilling rig, his trip to 851 mm. A three-speed gear box, the largest of its torque to 691 Nm, effective drilling thrust 2,145 kg. Design drill pipe smaller diameter of 41.3 mm, length of 762 mm, also with cone-shaped male connector, called ET / A-type drill pipe. ET / A-type and the initial ET / N-type drill pipe is the drainage of two standard gas drilling equipment, including in the United Kingdom is now No. 613/1974 of the Ministry of Coal samples.
Hydrack drilling rig is installed by the group composed of standard parts;
Drill - a rack with skateboards, skateboards support. Bit installed in the sliding seat, by the hydraulic motors, Biansuchilun me and thrust as well as sets of component supply rotary joint. On the rack, slide under the hydraulic cylinder. Bored end of the rack-oriented holder used to support the drill pipe and fixed.
Power equipment - which is equipped with a hydraulic oil tank, following a slip-ski, makes it easy to transport. A motor and hydraulic pump and other auxiliary equipment, such as the return to the oil filter, safety valve, and pumps, tank airway and humidity safety switches are installed in the fuel tank above.
Control panel - the smallest of the four devices. Bored functions include the control valve, pressure gauge and the instructions of torque on the drilling bit pressure.
Rack assembly - when the preparations for drilling, rack supports drilling rig. Rack to adapt to a variety of different forms of drilling terrain changes, H-rack, A-frame and single-bearing pillars. The latter two are based drilling rig users to the requirements of the design.
Hydraulic oil through hydraulic flexible hose from the power plant station transmitted to the control panel and then into the rig. General long hose 4 m, to adapt to the positioning devices.
