In the maintenance of mine underground loader, ensuring is a very important work. In order to ensure driving, it is necessary to carry out daily maintenance and overhaul of the vehicle. In the process of maintenance, the following measures are specially formulated to avoid accidents:

1、装载机进行保养、检查及修理时，车辆进入地沟里，用三角木或石块、砖头塞牢车轮，使车辆固定牢，在换轮胎时，用千斤顶顶起车辆后，一定要应用支撑工具支撑牢靠，不要用易碎易滑的砖石支撑。修理完毕，放松千斤顶时，应先观察周围是否有人或障碍物，只有确认人员都在位置时，矿用铲车开矿铁矿井下装载机A才能放松支撑工具、放松千斤顶。检查液压车箱的油管时，要待倾斜的车厢支撑牢靠后才可进行。

1. During the maintenance, inspection and repair of the loader, when the vehicle enters the trench, plug the wheels with triangular wood or stones and bricks to fix the vehicle firmly. When changing the tire, after jacking the vehicle with a jack, be sure to use support tools to support it firmly, and do not use fragile and slippery bricks and stones. After repair, when loosening the jack, first observe whether there are people or obstacles around. Only when it is confirmed that all personnel are in position, the underground loader a of mining forklift mining iron ore can loosen the support tool and loosen the jack. When checking the oil pipe of the hydraulic trunk, it can be carried out only after the inclined carriage is firmly supported.

2、在装载机发动机运转时是不允许进行检修的，熄火后若要马上进行检修，要特别注意预防排气管烫到身体。发动机水温很高时，更不要急于打开水箱盖，以防热水、热气喷出伤人。

2. Maintenance is not allowed when the loader engine is running. If maintenance is to be carried out immediately after flameout, special attention shall be paid to prevent the exhaust pipe from scalding the body. When the water temperature of the engine is very high, don't rush to open the water tank cover to prevent people from being hurt by hot water and hot gas.

3、矿用铲车开矿铁矿井下装载机A矿井装载机具有下列特点:

3. Mine forklift mining iron ore underground loader a mine loader has the following characteristics:

井下铲车采用铰接式车架,转弯半径小,机动灵活,便于在狭窄低矮场地作业。

The underground forklift adopts articulated frame, with small turning radius and flexible mobility, which is convenient for operation in narrow and low sites.

工作装置经计算机优化设计其结构更合理,具有强劲的铲掘力和较短的作业循环时间,工作效率更高.

The working device is optimized and designed by computer. It has more reasonable structure, strong digging force, shorter working cycle time and higher working efficiency

矿井装载机采用液力机械传动.能充分利用发动机的功率,加大扭矩使整机具有较大的牵引力同时还能适应外界阻力变化而自动无级变速,在充分提高发动机使用效率的同时延长传动机件和发动机的使用寿命.

The mine loader adopts hydraulic mechanical transmission. It can make full use of the power of the engine and increase the torque, so that the whole machine has large traction force. At the same time, it can adapt to the change of external resistance and automatic stepless speed change, so as to fully improve the service efficiency of the engine and prolong the service life of the transmission parts and engine

矿井装载机采用负荷传感、优先转向的分合流液压系统、动力换挡变速,整机操纵轻便灵活、动作平稳可靠.

The mine loader adopts load sensing, priority steering split and merge hydraulic system, power shift and speed change. The whole machine has light and flexible operation, stable and reliable action

矿井装载机采用低压宽基工程机械轮胎,后桥摆动,具有良好的越野和通过性能,适应崎岖不平的路面上行驶和作业.

The mine loader adopts low-pressure wide base construction machinery tires and the rear axle swings. It has good off-road and passing performance and is suitable for driving and working on rough roads

矿井装载机可拆卸驾驶棚,视野宽阔,为操作者提供舒服的工作条件。

The detachable driving shed of the mine loader has a wide field of vision and provides comfortable working conditions for the operator.

二、矿井装载机发动机:

2、 Mine loader engine:

发动机覆盖件采用度的结构,坚固,能够保护发动机,避免落物砸坏发动机.

The engine cover adopts a rigid structure, which can protect the engine from falling objects

三、矿井装载机变速器:

3、 Mine loader transmission:

矿用铲车开矿铁矿井下装载机，采用YJ-280型单级三元件变矩器，可靠性高,维修方便

Yj-280 single-stage three element torque converter is adopted for the underground loader of mining forklift mining iron mine, which has high reliability and convenient maintenance

矿井装载机采用动力换档变速箱,可靠性高,维修方便。

The mine loader adopts power shift gearbox, which has high reliability and convenient maintenance.

四、矿井装载机废气处理系统

4、 Waste gas treatment system of mine loader

矿用铲车开矿铁矿井下装载机A发动机排出的废气通过两级过滤，在空气流通不畅的空间内工人作业的健康问题。

The exhaust gas discharged from the engine of underground loader a of mine forklift mining iron mine passes through two-stage filtration, which is a health problem for workers working in a space with poor air circulation.

小型装载机保护链是一种延长轮胎使用寿命，安装在小型装载机轮胎上的金属网状物。一般的小型装载机保护链只是保护轮胎的正面，内外侧均有部分受到外部环境的创伤。为了更保护轮胎的使用寿命，全包型保护链了轮胎内外侧易受创伤的问题，轮胎外侧全部被保护链包严，防止了轮胎外侧的创伤，轮胎内侧加密了网状物的排列，防护效果更加可靠。

The protection chain of small loader is a metal mesh installed on the tire of small loader to prolong the service life of the tire. The general small loader protection chain only protects the front of the tire, and the inner and outer sides are partially injured by the external environment. In order to better protect the service life of the tire, the all inclusive protection chain solves the problem that the inner and outer sides of the tire are vulnerable to trauma. All the outer sides of the tire are wrapped tightly by the protection chain to prevent trauma on the outer side of the tire. The arrangement of mesh is densified on the inner side of the tire, and the protection effect is more reliable.
