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、机型的选择

1. Selection of models

在购买井下装载机时主要依据作业环境和功能用途上进行选择。如果是在采石场和软基地进行作业，多选用履带式装载机。

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、动力的选择

2. The choice of motivation

一般多采用工程机械专用柴油发动机，在特殊地域作业，如海拨高于3000m的地方，应采用特殊的高原型柴油发动机。

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、传动型式的选择

3. Selection of transmission type

一般选用液力——机械传动其中关键部件是变矩器形式的选择。目前我国在生产的装载机多选用双涡轮、单级两相液力度矩器。

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、其他注意事项

4. Other considerations

在选用井下装载机时，还要充分考虑装载机的制动性能，包括多个在制动、停车制动和紧急制动三种。制动；器有蹄式、钳盘式和湿式多片式三种。制动器的驱动机构一般采用加力装置，其动力源有压缩空气，气顶油，和液压式三种。目前常用的是气顶油制动系统，一般采用双回路制动系统，以提高行驶的性。

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，我们在施工时更不能忽略对机械采取正确、规范的操作方式方法以及对机械的维护。希望以上内容可以对您有所帮助，想要更多的精彩内容可以直接关注：http://www.kuangjingjixie.com
