The loading machine is a kind of earth and stone construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used to shovel bulk materials such as soil, sand, lime, coal, hard soil, etc. for light shovel excavation. It can also carry out bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices.
What is the main structure of the loading machine?
What is the main purpose of the loading machine?
How to choose a loading machine?
The loading machine includes engine, torque converter, gearbox, front and rear drive axles, referred to as four major parts.
1. Engine
2. There are three pumps on the torque converter, the working pump (supplying pressure oil for lifting and dumping bucket), the steering pump (supplying steering pressure oil), the variable speed pump, also known as the traveling pump (supplying torque converter, transmission pressure oil), some models The steering pump is also equipped with a pilot pump (supplying pilot pressure oil for the control valve).
3. Working hydraulic oil circuit, hydraulic oil tank, working pump, multi-way valve, lift cylinder and dump cylinder
4. Traveling oil circuit: transmission oil sump oil, travel pump, all the way into torque converter and one into gear valve, transmission clutch
5. Drive: drive shaft, main differential, wheel reducer
6. Steering oil circuit: fuel tank, steering pump, steady flow valve (or priority valve) steering gear, steering cylinder
7. There are two types of gearboxes: integrated (planetary type) and split (fixed shaft type).
The loading machine is mainly used for shoveling, loading, unloading, earth moving and bulk materials such as stones, and it can also perform light shoveling operations on rocks and hard soils. If you change different working devices, you can also complete the work of bulldozing, lifting, loading and unloading other materials. In highway construction, the loading machine is mainly used for filling and excavating roadbed engineering, aggregate and loading of asphalt and cement concrete yard. Because it has the advantages of fast operation speed, good maneuverability and easy operation, it has developed rapidly and has become the main machinery in earthwork construction.
1. Selection of models: The selection and determination are mainly based on the operation occasion and use. Generally, the operation is carried out in quarries and soft bases, and tire loading machines are often used with snow chains;
2. Choice of power: The loading machine generally uses diesel engines for construction machinery. In special areas, such as places with an altitude higher than 3000m, special plateau diesel engines should be used;
3. Selection of transmission type: hydraulic-mechanical transmission is generally used. One of the key components is the choice of torque converter form. Generally, the common loading machines on the market mostly use twin-turbo, single-stage two-phase hydraulic torque converters.
Jiangsu Shangqi Heavy Industry Technology Co. Ltd was established in 2002 and is located in the economic development zone of Jingjiang city, enjoying convenient transportation and beautiful environment.
