A loader according to an embodiment of the present invention will be described with reference to fig. 1 to 4.
It should be noted that a loader, also called a forklift, is often applied in the field of construction engineering, the construction environment is often relatively complicated, and the loader is mainly used for shoveling bulk materials such as soil, gravel, lime, coal and the like, and can also carry out slight shoveling operation on ores or hard soil and the like. The different auxiliary working devices can be replaced to carry out bulldozing, hoisting and other material loading and unloading operations such as wood. In road construction, particularly in high-grade highway construction, the loader is used for filling and digging of roadbed engineering, and collecting and loading of asphalt mixture and cement concrete yards. Besides, the machine can also carry out the operations of pushing and transporting soil, scraping the ground, pulling other machines and the like. The loader has the advantages of high operation speed, high efficiency, good maneuverability, light operation and the like, so the loader becomes one of the main types of earthwork construction in engineering construction.
As shown in fig. 1, 2 and 3, the present invention provides a loader comprising: a front frame 10, a rear frame 20, a non-contact angle sensor 30, a panoramic image capture device 40, and a controller 50.
The front frame 10 is hinged to the rear frame 20, and the front frame 10 and the rear frame 20 are rotatable about a rotation axis.
The front frame 10 belongs to a working implement, the front frame 10 may include a bucket for loading materials, the front frame 10 may have front wheels, the front wheels may be steering wheels, the front wheels may have no driving force, and only follow-up may be achieved.
The rear frame 20 belongs to a power tool, the rear frame 20 provides power for the loader, and the rear frame 20 can be provided with rear wheels, and the rear wheels have driving force, namely the rear wheels are driven by a power system to rotate, so that the loader is driven to move integrally.
It should be noted that the shoveling and loading and unloading operations of the loader are performed by the movement of the work implement. The loader working device comprises a bucket, a movable arm, a connecting rod, a rocker arm, a rotary bucket oil cylinder, a movable arm oil cylinder and the like. The entire front frame 10 is hinged to the rear frame 20. The bucket is hinged with the rotary bucket oil cylinder through a connecting rod and a rocker arm and is used for loading and unloading materials. The movable arm is hinged with the frame and the movable arm oil cylinder and used for lifting the bucket. The turning of the bucket and the lifting of the movable arm are controlled by hydraulic pressure.
The working machine should ensure that: when the rotary bucket oil cylinder is locked and the movable arm oil cylinder is lifted or landed, the connecting rod mechanism enables the bucket to translate up and down or approach translation so as to prevent the bucket from tilting to scatter materials; when the movable arm is in any position and the bucket rotates around the hinge point of the movable arm to unload, the inclination angle of the bucket is not less than 45 degrees, and the bucket can be automatically leveled when the movable arm descends after unloading. At present, the loader mainly has seven types, namely, the loader is divided into three-rod type, four-rod type, five-rod type, six-rod type, eight-rod type and the like according to different member numbers of the link mechanism; the mechanism is divided into a forward rotation link mechanism and a reverse rotation link mechanism according to whether the input rod and the output rod are in the same rotation direction or not.
The loader bucket structure for the earthwork is characterized in that a bucket body is made of low-carbon, wear-resistant and high-strength steel plates in a welding mode, a cutting edge is made of wear-resistant medium manganese alloy steel materials, and a side cutting edge and a reinforcing angle plate are made of high-strength wear-resistant steel materials. The shapes of the bucket blades are classified into four types. The tooth profile is selected taking into account insertion resistance, wear resistance and ease of replacement. The tooth profile is divided into sharp teeth and blunt teeth, the tire type loader mostly adopts sharp teeth, and the crawler type loader mostly adopts blunt teeth. The number of the bucket teeth depends on the bucket width, and the bucket teeth distance is generally 150mm to 300 mm. The bucket tooth structure is divided into an integral type and a split type, wherein the small and medium-sized loaders are mostly integrated, and the large-sized loaders are usually split due to poor operation conditions and serious bucket tooth abrasion. The split bucket tooth is divided into a basic tooth 2 and a tooth tip 1, and only the tooth tip needs to be replaced after the tooth tip is worn.
The non-contact angle sensor 30 is disposed in a hinge region between the front frame 10 and the rear frame 20, and the non-contact angle sensor 30 is used to acquire angle information between the front frame 10 and the rear frame 20.
