Technical Sample Three


All drilling functions are controlled from the operator's cab lo-cated at the rear of the machine, adjacent to the drilling plat-form. The operating controls and gauges are positioned within easy reach of the operator from the adjustable operator seat. The large cab windows provide good visibility of the drilling opera-tion. The machinery house encloses all main machinery and electri-cal equipment and provides ample space for maintenance and repair purposes.


所有的鑽進功能都是從機器後面靠近鑽進平臺的操作室裏控制的,操作員從可調座椅上可以很容易地接近各種操作控制和儀錶,操作室窗戶大,可以很好地觀察鑽進作業。機房包含所有主要機器以及電氣設備,並提供充裕的空間供維護和修理之用。

The machinery house air is pressurized and fil-tered by two fan units, one of which is thermostatically con-trolled. The other fan can be throttled down to minimize the amount of air brought in during cold weather operation.


機房空氣爲正壓,並有兩層風扇送風裝置進行空氣過濾,其中一個具有恒溫控制。冷天作業時,另一個風扇的進氣量可以調低,以減少機房的進氣量。

The systems that support the drilling and propelling functions of the drill are controlled by a combination of electric, hydraulic, and pneumatic components. A description of each major system follows.


爆破鑽支援鑽進和推進的系統是由一組電氣、液壓和氣動部件控制的。下面對每個主要的系統加以說明。

LEVELING JACKS. Leveling jacks, located at the four corners of the main frame, are controlled from the operator's cab. The two rear jacks (those closest to the mast) are independently ad-justable. The two front jacks operate as a pair, and self-equalize when extended or retracted.


調平千斤頂。位於主機架四角的調平千斤頂是從操作室控制的。靠近支架的兩個背後的千斤頂可以獨立調節。前面的兩個千斤頂伸出或縮回是成對操作的,並可以進行自平衡。

An auto-leveling system is available as an option, which, when activated, will automatically raise the drill to a level operating plane at the lowest possible elevation for good machine stabili-ty.


另有自動調平系統選件可供,啓用該選件時,即會自動將爆破鑽提升到一個盡可能低的水平操作平面,以獲得良好的機器穩定性。


PROPEL SYSTEM. The drill is mounted on and propelled by individually controlled and individually powered crawlers. The rear axle is stationary, and is bolted rigidly to the main frame. The front axle is connected to a floating equalizer axle that en-ables the crawler assemblies to maintain footing over rough ter-rain.


推進系統。爆破鑽安裝在單獨控制和單獨提供動力的履帶牽引裝置上,並由其推進。後軸是固定的,用螺栓剛性固定在主機架上。前軸連接到一個浮動的平衡軸上,使得牽引裝置在高低不平的地面上能夠保持穩定。

Steering is accomplished by controlling the individual left and right crawlers. Each crawler drive has a spring-set/hydraulic released parking brake that is automatically released when pressure is applied to the hydraulic motor.


轉向是通過單獨控制左右牽引裝置來完成的。每個牽引驅動裝置都有一個彈簧組/液壓釋放的停車刹車,當壓力應用於液壓馬達上時,停車刹車即會自動脫開。

MAST AND BACKBRACE ASSEMBLIES. The mast assem-bly supports the rotary drill head and its hoisting mechanism. The mast is raised to the working position by a pair of hydraulic cylinders, and is locked in the vertical drilling position by two hydraulically actuated mast anchor pins.


支架和背撐臂元件。支架元件支援轉動鑽頭及其提升機構。支架通過一對液壓缸提升到工作高度,並通過兩個液壓啓動的錨定銷鎖定在垂直鑽進位置。

The back brace locks release, allowing the mast backbraces to fold automatically when the mast is lowered from the vertical position.


背撐臂可鎖定脫扣,當支架從垂直位置上降下來時,允許支架背撐臂自動折疊起來。

All mast raising and lowering functions are controlled from the operator's cab.


支架的所有升降功能都是從操作室控制的。

PIPE RACK. The standard pipe rack configuration for this drill consists of a long pipe cradle that is fastened to a pair of paral-lelogram- type swing arms. The swing arms are fastened to the inside structure of the mast, and permit the pipe rack to be low-ered from the stored position to the centerline of the drill string. Up to three racks can be mounted to the mast, depending on the option selected.


管架。本鑽機的標準管架配置由一個長管道托架組成,該托架被固定在兩個平行四邊形的旋臂上。兩個懸臂則固定在支架的內部結構上,並允許管架從貯存位置降到鑽柱中線上。根據所選擇的選件,支架上可安裝三個管架。

Each rack assembly can store a single section of drill pipe. The pipe is restrained within the pipe rack by a 'pot' at the bottom and by a swing clamp mechanism located at the top of the pipe rack. When a pipe is loaded into the rack and is inserted into the pot, an electric limit switch signals the PLC to energize a cylin-der on the gate, which closes the swing gate, thereby capturing the pipe. Pipe wrench dogs within each pipe rack pot are used to loosen the pipe from the rotary head coupling, when return-ing drill pipe to the rack.


每個管架元件可貯存一種單一長度的鑽管。管道在管架的底部被限制在一個“罐子”裏,在管架的上部則通過一個擺動式箝位機構來限制。當一根管子裝到管架上並插入罐子裏後,一個電限位元開關即通知PLC爲門上的一個壓力缸提供能量,該壓力缸則關上擺動門,於是就抓住了管子。當將鑽管放回管架上時,用每個管架罐內的管鉗爪將管子從轉動管接頭上鬆開。

The pipe racks are moved to and from their stored position by a hydraulic cylinder attached between the mast frame and the lower swing arm.


管架是通過一個裝在支架框和下搖動臂之間的液壓缸往返於其貯存位置的。

ROTARY CARRIAGE. The rotary carriage provides rotary and vertical motion to the drill string and bit. It consists of a car-riage, a rotary gear reducer and a hoist gear reducer. The rotary gear reducer is driven by a DC motor through a gearbox to pro-vide bi-directional drill bit rotation.


轉動滑架。轉動滑架爲鑽柱和鑽頭提供轉動和垂直移動。它由一個滑架、一個轉動齒輪減速器和一個提升齒輪減速器組成。轉動齒輪減速器是由一個直流電機驅動的,通過一個齒輪箱爲鑽頭提供雙向轉動能力。

Vertical motion of the carriage is provided by a pulldown gear case coupled by two pinions to racks on the mast. The input power is also provided by a DC motor.


滑架的垂直移動是由一個下拉齒輪箱提供的,該下拉齒輪箱則通過兩個小齒輪連接到支架上的齒條上。輸入動力也是由直流電機提供的。

POWER UNIT. The hydraulic pump drive and the air compres-sor are mounted on opposite ends of an electric drive motor on a common sub-base (see Figure 1-2). The motor provides the power to drive all of the hydraulic functions of the drill and the air compressor which provides the large volume flow of com-pressed air needed for removal of drilling debris from the blast-hole.


動力裝置。液壓泵驅動裝置和空氣壓縮機分別安裝在位於公用基底層上一個電動機相反的兩端。該電動機提供動力,驅動爆破鑽和空氣壓縮機的所有液壓功能,空氣壓縮機提供除去由鑽孔裏帶出的鑽進碎屑所需要的大容量壓縮空氣流。

PUMP DRIVE TRANSMISSION (PDT). All of the pumps which feed the main and auxiliary hydraulic systems are con-nected to, and driven by, a single pump drive transmission (PDT). The PDT is a gear reducer having multiple output shafts, all driven from a common input shaft.


泵驅動變速器(PDT)。爲主液壓系統和輔助液壓系統供液的所有的泵都連接到一個泵驅動變速器(PDT)上,並由之驅動。該泵驅動變速器是一個齒輪減速箱,具有多個輸出軸,全部由同一個輸入軸驅動。
