① 煤电钻能够适用于高硬度岩石凿岩吗
一般钻进以水为排渣清孔动力,所以,即使搞降水,作业场地也比较泥泞.仅适台履带式钻机作业配备液压蕾岩机或大扭矩回转钻进,机重约8吨,回转扭矩约700kgm,提升力约8吨为适宜.
② 安装扳道器时应注意哪些
①电气设备的安装与电缆敷设应安设在顶板无淋水和底板无积水的地方,应不妨碍人员通行,距轨道和钢丝绳应大于等于600mm的距离,避免影响运输车辆运行。
②电缆应使用电缆钩悬挂,严禁用铁线悬挂。
③橡套电缆之间的直接连接必须采用冷压、冷补工艺。
④用人力敷设电缆时,应将电缆顺直,在巷道拐弯处不能过紧。人员应在电缆外侧搬运,电缆悬挂的间距为1.2m。
⑤工作面与顺槽拐角处的电缆要吊挂牢固,禁止在上三角区吊挂电缆。
⑥搬运电气设备时,要绑扎牢固,禁止超宽超高。要听从现场负责人指挥,防止碰人和损坏电气设备。
⑦严禁带电搬运电气设备和缆线。
③ 道岔是不是必须要有扳道器
首先,题目问得有问题,扳道器是众多道岔转辙设备中的一种,应该问道岔是否必须应配置道岔转辙设备,这是必须要有的,否则就失去了设置道岔的目的;其次,只有人工扳道的道岔才使用扳道器,现在早已进入电气化铁路采用信号控制的时代了,扳道器已在正线线路彻底退出了。
④ 怎么区分道岔左开还是右开的简洁明了点
如果火车从右往左行驶,道岔就是左开;如果火车从左往右行驶,道岔就是右开。也就是说单开道岔的话,面对尖轨方向,杆件伸出位置就是左开右开的位置。
道岔是把一条轨道分支为两条或两条以上的轨道,使机车车辆由一条线路转往另一条线路的基本设置。道岔是特殊的轨道设备,不仅影响列车运行安全,而且使用寿命也比其他设备短,养护维修工作量大。
我国用的单开道岔,其主线为直线,侧线由主线向左或向右岔出,也称左开道岔和右开道岔,其数量占各类道岔总数的90%以上。
单开道岔的构造和类型
单开道岔由转辙器、辙岔、护轨及连接部分和岔枕组成。转辙器是用来引导机车车辆由正线转向侧线或由侧线转向正线的转向设备;辙岔及护轨是使机车车辆的车轮由一股钢轨越过另一股钢轨的过渡设备;转辙器和辙岔由连接部分连接。
转辙器由一对尖轨、一对基本轨、转辙装置及一些连接零件所组成。转辙装置也称扳道器,由闸座及道岔表示器、拉杆、拐杆等组成,以来操作尖轨的左右摆动以及改变道岔的开通方向。辙岔设置于道岔侧线钢轨与主线钢轨的相交处,护轨设于辙岔的两侧。

SL-120 type of flexible railway switch
Manual
A summary
1. SL-120 type of flexible railway switch (Abbreviations: railway switch) is a manual switch turnout equipment.
2. To its spring tension to achieve the turnout to be anti-bit conversion, and will be maintained at its anti-bit capability.
3. Easily apply to "squeeze bifurcated fault" circumstances turnout, once crowded bifurcated not damaged equipment.
4. Lock will be on the base axis of penetration and the locking hole with padlock to lock in turnout for anti-bit state to facilitate a bifurcated traffic safety.
The proct features
1. Handle length scalable 290 MM, when the turnout conversion little resistance, length can be shortened handle the contrary, the extension handle length.
2. Handle扳动itinerary for the decrease, to handle the rotating 180 degrees to facilitate human operator.
3 above telescopic handle with rotating the casing by spring sales of the two filed, after falling into the adjustment to achieve.
4. To overcome扳动resistance, the controller design for the core head slider structure, its structure扳动flexible.
5. Rectangular Shui rotating spindle center, equipped with roller bearing, raising proct life and accuracy.
6. Where rotation axis between holes, are equipped with a self-lubricating properties of materials bush.
7. Rod connected with the turnout, using the fine-tuning, in the use after the installation process, not dismantle its connecting pin, the turnout openings can be posted and the state of adjustment.
Three technical parameters
1. Apply ≤ 120 mm openings Turnout
2. Applicable conversion turnout resistance ≤ 1960 N (200KG)
3. Rod largest linear displacement of 209 mm
4. Installation of the two枕木center distance 650 mm, with the rod tip Department枕木two bifurcated centerline distance of 350 mm
5. Installation of the double-track railway lines in the middle, adjustable handle from the center line on both sides should be ≥ 22.5 mm
Principle and the installation of four structural adjustment (see the installation diagram)
1. Gauge before installation, inspection, the turnout laying parameters枕木placed spacing is consistent with the relevant technical standards.
2. Installed before use撬棍respectively拨动two apical orbit so close affixed to the basic track-inspection bifurcated Tsim and刨切paragraph of whether the stickers, a non-bifurcated sharp gap best,刨切of the gap should not be large at 1 mm.
3. Angle steel structure will be the installation of devices, one end with 22 mm × 145 mm solid wood screw道钉pinch points in turnout traction on both sides of the wooden pillow-head, the other side needs in line, the laying of a wooden pillow, in the same pinch solid wood枕上.
4. Rod side and right-angle Shui, for fine-tuning the other side of the bar association and the turnout connected together.
5. When railway switch device with the turnout has been fixed link integrity, the first to tie the handle perpendicular to the center position, that is a right angle Shui are also at the middle position; began to adjust the fine-tuning the entire rod, the two apical track for turnouts respectively with straight, curly basically the same size opening track. Turnout orifice size should be open for one half, that is, 60 mm.
6. Completed on the basis of the above adjustments, the first pull to handle one end, a sharp track and check whether the basic track of stickers, if space, use fine-tuning device to be corrected if there is still space, adjusting the compression spring nut to increase Spring tension until the secret stickers. Then handle pull to one end, the same method used to adjust the above, also reached the other side of stickers.
7. In the following two circumstances, the handle can be shortened length.
(1) When converting Turnout little resistance when human can扳动
(2) when the turnout in the set, anti-places, for reced vertical height handle
Whether or shrinkage handle extended its length, method of operation, has filed handle casing on two spring sales and rotating 90 degrees, casing from the connecting rod and handle the role, can hold length adjustment. And then rotated 90 degrees so that the spring-pin inserted into the hole in the handle and restore connectivity role.
8. Handle railway switch to rece the itinerary to facilitate human operators, to handle the curved shape. So pull from one end to one end, according to the length of the methods of operation telescopic handle, to be rotating 180 degrees for the next扳动facilitated.
9. Structure for the railway switch principle is: rotating through rectangular Shui can be certain angle to the rectangular Shui一臂can handle拨动, and the other arm with a certain tension on the composition of the spring. Tension role in the spring, according to Cartesian Shui not stagnation in the middle of the principle, in tension with a spring rod arm hang, in a Cartesian Shui rotation angle are the two ends have some traction, providing impetus to the conversion Turnout .
Five Maintenance
1. Use of the ministries should be guaranteed complete fasteners, bolts fastening, opening a sales arm angle to prevent loss provisions.
2. Connecting pin in the hole should wear Kuang of not more than 1 mm, excessive Kuang be timely replacement of connecting pin.
3. Should ensure that the turnout conversion process, the ministries movements smooth, rotating flexible, non-card resistance phenomenon.
4. Pin and Hole, the first with the slider handle inter should regularly coated surface oil, and maintain lubrication good.
