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 the Transport Machinery class, not only can shovel the bulk pieces such as sand loading soil, coal, ore, can also shovel materials such as digging ore, pan soil.Its shovel dress equipment is the main member of completing the loader various functions, and external major vendor has the Caterpillar of the U.S., the Komatsu of Japan, domestic Chinese patent
CN201843153UBe characterized in increasing the action effect of connecting rod, the impact force when having effectively reduced discharging has improved the comfortableness of operation; Chinese patent
CN201280730Be characterized in guaranteeing the clean and tidy safety that also can improve operation of loader working environment, avoided because of the scraper bowl inaccurate operation repeatedly that resets, reduced operating personnel's labour intensity, service behaviour and the operating efficiency of loader have been improved, but all having in swing arm lifting process, above-mentioned two patents may form mechanism's deadlock phenomenon, 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, can prevent that stopper arms produces the locked mechanism of wheel loaders that contains anti-locking device in lifting process.the present invention mainly comprises frame, swing arm, the swing arm hydraulic cylinder, the swing arm connecting rod, scraper bowl, the scraper bowl hydraulic cylinder, dipper stick, bearing bar, rocking arm, wherein, frame is connected with an end of a pair of 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 of 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 of bearing bar by hinge, this is connected by hinge and frame another position an end of bearing bar, its other end is connected with an end of a pair of swing arm connecting rod by hinge, the other end of this swing arm connecting rod leans on the both sides at a position of frame one side to be connected by hinge and above-mentioned swing arm, the cylinder sleeve end of a pair of scraper bowl hydraulic cylinder is connected with above-mentioned frame another position by hinge, this piston rod end to the scraper bowl hydraulic cylinder is connected with an end of rocking arm by hinge, the middle part of this rocking arm is connected with the middle part of above-mentioned swing arm by hinge, this other end to rocking arm is connected with an end of dipper stick by hinge, 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 has following advantage:
1, the shorter distance of swing arm hydraulic cylinder travel just can realize the lifting effect of the larger distance of swing arm, thereby can reduce energy consumption.
2, can prevent that stopper arms produces in lifting process locked.
Description of drawings
Fig. 1 is three-dimensional simplified schematic diagram of the present invention.
The specific embodiment
In the three-dimensional simplified schematic diagram of a kind of mechanism of wheel loaders that contains anti-locking device shown in Figure 1, frame 1 is connected with an end of a pair of swing arm 9 by hinge R6, and the other end of this swing arm passes through hinge R11 and is connected with a position of scraper bowl 8; The cylinder sleeve end of a pair of swing arm hydraulic cylinder 2 is connected with frame by hinge R1, the piston rod end of this swing arm hydraulic cylinder is connected with the middle part of a pair of bearing bar 3 by hinge R3, this end to bearing bar is connected with frame by hinge R2, its other end is connected with an end of a pair of swing arm connecting rod 4 by hinge R4, and this leans on the both sides at a position of frame one side to be connected by hinge R5 with above-mentioned swing arm to the swing arm connecting rod; The cylinder sleeve end of a pair of scraper bowl hydraulic cylinder 5 is connected with frame by hinge R2, this piston rod end to the scraper bowl hydraulic cylinder is connected with an end of rocking arm 6 by hinge R7, the middle part of this rocking arm is connected with the middle part of above-mentioned swing arm by hinge R8, the other end of this rocking arm is connected with an end of dipper stick 7 by hinge R9, and the other end of this dipper stick is connected with another position of scraper bowl by hinge R10.
