1. Basic operation function and operation method of loader
1. Excavation
The excavation operation is the operation of stopping or advancing the vehicle, inserting the bucket into the deposits such as sand, soil and rock, and loading the shovel. Excavation operations are divided into shoveling operations and earthmoving operations. When carrying out excavation, load the load on both sides of the bucket evenly. Do not allow only one side to carry the load so that the loader is directly in front of you and not angle the front and rear frames.
2. Loading operation (handling engineering method)
The operation of pouring sand, rock, ore, etc. into trucks, trucks, and containers can be carried out with high-efficiency methods. According to the situation on the spot, the handling engineering method must be determined first: there are mainly the matching engineering methods of the loader and the transport vehicle and the loading and transportation engineering method using only the tire loader.
Supporting engineering methods for loaders and transport vehicles
As shown in the figure, there are 4 kinds of operation methods. According to the situation on the job site, you can choose the operation method with a short cycle time (one-time loading time)-the loading and transportation engineering method.
The above method uses a tire loader to shovel, transport, and pour continuously. Usually suitable for handling distances of 30 to 100m.
3. Uninstall operation
When dumping materials into the car or freight yard, the boom should be raised so that the bucket (tilt forward to the maximum inclination angle position) can not reach the car box and the stockpile. The control of the joystick can be completely unloaded or unloaded. When unloading, it is required to relax the action to reduce the impact of the material on the truck. When the material sticks to the bucket, the bucket control lever can be moved back and forth to make the bucket vibrate and fall off the material.
4. Site preparation
The angle formed by the front tip of the bucket and the bottom surface can be used for soil preparation, leveling and foundation laying. The site preparation work must be carried out by retreating the vehicle.
5. Fill-in operation
If the bucket is used as a dozer blade, the filling operation can be performed.
At this time, the bucket is full of sand and soil to keep it level with the ground for work.
Second, the expansion of loader construction conditions and functions
The adaptability of the loader to the construction conditions and the expansion of the operation function are mainly reflected in the following two aspects:
1. The directional study of system configuration, the loader can adapt to the use requirements of various harsh environments.
At present, the more typical models for mass sales and applications in the market are: high-prototype loaders, rock loaders, desert loaders, and side dump loaders dedicated to tunnel operations and used for high temperature furnace slag removal Working heat-resistant loader, the functional extension of these loader 名媛直播 fill the edge market that ordinary loader can not replace.
2. The diversified working tools are equipped, and have the function of quickly replacing various types of tools.
This type of loader is generally called a multi-function loader, and the working device structure uses a combined eight-bar mechanism, which has the characteristics of parallel movement from the ground to the entire lifting height range. It designs the quick connector and bracket-type mechanism as an integrated working device, and completes loading and unloading, gripping, stacking, snow sweeping, leveling, sweeping the road, bulldozing, lifting, handling and surface drilling by quickly replacing different auxiliary mechanisms Drilling, crushing and other operations to achieve one machine with multiple functions and reduce user equipment investment.
3. The future development trend of loader functions and construction technology
1. In recent years, the wheel loader has been centered on the application of new technologies, multi-functional machines, modular design and improved efficiency, and has continued to develop into large-scale and miniaturized 名媛直播. It has continuously introduced new 名媛直播 and accelerated replacement.
2. New structural work organizations are constantly emerging
The hydraulic system of the working device adopts a lifting limit device and a lowering automatic positioning device, which avoids the high pressure and impact of the hydraulic cylinder at the end of the mechanical limit; the installed accumulator can absorb the impact load and start the vertical swing of the whole machine Damping effect; the technology that is more mature and widely used today is a technical scheme that uses electrical control to switch the pilot control circuit of the working hydraulic system.
3. The design of the driver's cab
The design of the driver's cab of the new wheel loader fully considers the physiological needs of people. The arrangement of instruments, operation handles and pedals, driver's seat, visibility, noise prevention and vibration isolation, temperature adjustment, etc. are all ergonomic, making The driver operates in a comfortable, relaxed and safe environment to improve work efficiency.
4. Reduce the cost of construction projects for equipment users from the perspective of improving operating efficiency
Due to the continuous improvement of technology, performance and application range of wheel loaders, the reliability, maneuverability and adaptability of loading hard materials have been fully developed. . In the 21st century, automated and intelligent wheel loaders with higher efficiency, more convenient maintenance and better comfort will be introduced to the market.
