Abstract
The invention discloses a loading machine mechanism with an anti-lock device, wherein a rack is hinged with one end of a movable arm, the other end of the movable arm is hinged with a bucket, the end part of a cylinder sleeve of a movable arm hydraulic cylinder is hinged with the rack, the end part of a piston rod of the movable arm hydraulic cylinder is hinged with the middle part of a bearing rod, one end of the bearing rod is hinged with the rack, the other end thereof is hinged with one end of a movable arm connecting rod, the other end of the movable arm connecting rod is hinged with two sides of the movable arm, the end part of a cylinder sleeve of a pair of bucket hydraulic cylinders is hinged with the rack, the end part of the piston rod of the pair of bucket hydraulic cylinders is hinged with one end of a rocking arm, the middle part of a pair of rocking arms is hinged with that of the movable arm, the other end of the pair of rocking arms is hinged with one end of a bucket connecting rod, and the other end of the bucket connecting rod is hinged with a part of the bucket. The loading machine mechanism with the anti-lock device has the advantages of energy consumption reduction, capability of preventing the movable arm from being dead locked during the lifting process, and the like.
Description
technical fieldthe present invention relates to a kind of mechanism of wheel loaders.
Background technology
Loader belongs to Transport Machinery class, not only can shovel the bulk blocks such as sand loading soil, coal, ore, can also shovel and dig the material such as ore, pan soil.Its shovel dress equipment has been the main member of loader various functions, and external major vendor has the Caterpillar of the U.S., the Komatsu of Japan, domestic Chinese patent
cN201843153Ube characterized in the action effect that can increase connecting rod, effectively reduce impact force during discharging, improve the comfortableness of operation; Chinese patent
cN201280730be characterized in ensure that the clean and tidy of loader working environment and the safety that can improve operation, avoid because of the inaccurate operation repeatedly of scraper bowl reset, reduce the labour intensity of operating personnel, improve service behaviour and the operating efficiency of loader, but above-mentioned two patents all have possibility formation mechanism deadlock phenomenon in swing arm lifting process, and the high shortcoming that consumes energy.
summary of the inventionthe object of the present invention is to provide and a kind ofly can reduce energy consumption, the locked mechanism of wheel loaders containing anti-locking device can be produced by anti-stopper arms in lifting process.The present invention mainly comprises frame, swing arm, swing arm hydraulic cylinder, swing arm connecting rod, scraper bowl, bucket hydraulic cylinder, dipper stick, bearing bar, rocking arm, wherein, frame is connected with one end of a pair swing arm by hinge, the other end of this swing arm is connected with a position of scraper bowl by hinge, the cylinder sleeve end of a pair swing arm hydraulic cylinder is connected with a position of frame by hinge, the piston rod end of this swing arm hydraulic cylinder is connected with the middle part of a pair bearing bar by hinge, this is connected by another position of hinge and frame one end of bearing bar, its other end is connected by hinge one end with a pair swing arm connecting rod, the other end of this swing arm connecting rod is connected with the both sides of above-mentioned swing arm by a position of frame side by hinge, the cylinder sleeve end of a pair bucket hydraulic cylinder is connected with another position of above-mentioned frame by hinge, this is connected with one end of rocking arm by hinge the piston rod end of bucket hydraulic cylinder, the middle part of this rocking arm is connected by the middle part of hinge with above-mentioned swing arm, this is connected with one end of dipper stick by hinge the other end of rocking arm, and the other end of this dipper stick is connected with another position of above-mentioned scraper bowl by hinge.
The present invention compared with prior art tool has the following advantages:
1, the distance that swing arm hydraulic cylinder travel is shorter just can realize the lifting effect of the larger distance of swing arm, thus can reduce energy consumption.
2, can anti-stopper arms produce in lifting process locked.
Accompanying drawing explanation
Fig. 1 is three-dimensional simplified schematic diagram of the present invention.
