In order to obtain higher operation efficiency and improve the construction economy through the auxiliary function of machinery in the actual engineering construction, the premise is to purchase high-performance mechanical equipment. In this regard, we take the selection of underground loaders as an example to make the following analysis:

1、機型的選擇

1. Selection of models

在購買井下裝載機時主要依據(jù)作業(yè)環(huán)境和功能用途上進行選擇。如果是在采石場和軟基地進行作業(yè)，多選用履帶式裝載機。

When purchasing the underground loader, it is mainly based on the working environment and function. If the operation is carried out in quarry and soft base, crawler loader is often used.

2、動力的選擇

2. The choice of motivation

一般多采用工程機械專用柴油發(fā)動機，在特殊地域作業(yè)，如海撥高于3000m的地方，應(yīng)采用特殊的高原型柴油發(fā)動機。

In general, special diesel engines for construction machinery are mostly used, and special plateau diesel engines should be used when operating in special areas, such as places with sea level higher than 3000m.

3、傳動型式的選擇

3. Selection of transmission type

一般選用液力——機械傳動其中關(guān)鍵部件是變矩器形式的選擇。目前我國在生產(chǎn)的裝載機多選用雙渦輪、單級兩相液力度矩器。

Generally, hydraulic mechanical transmission is selected, and the key component is the selection of torque converter. At present, the loaders in our country mostly use double turbine and single-stage two-phase liquid torque converter.

4、其他注意事項

4. Other considerations

在選用井下裝載機時，還要充分考慮裝載機的制動性能，包括多個在制動、停車制動和緊急制動三種。制動；器有蹄式、鉗盤式和濕式多片式三種。制動器的驅(qū)動機構(gòu)一般采用加力裝置，其動力源有壓縮空氣，氣頂油，和液壓式三種。目前常用的是氣頂油制動系統(tǒng)，一般采用雙回路制動系統(tǒng)，以提高行駛的性。

When selecting the underground loader, the braking performance of the loader should be fully considered, including multiple in braking, parking braking and emergency braking. Braking; There are shoe type, clamp plate type and wet multi plate type. The driving mechanism of the brake generally adopts the afterburner, and its power sources are compressed air, air top oil and hydraulic. At present, the commonly used is the air top oil braking system, which generally adopts the double circuit braking system to improve the driving safety.

除此之前，我們在施工時更不能忽略對機械采取正確、規(guī)范的操作方式方法以及對機械的維護。希望以上內(nèi)容可以對您有所幫助，想要更多的精彩內(nèi)容可以直接關(guān)注：http://yygsbaby.com
