Description
Technical field
The present invention is mainly concerned with the hoisting crane field, refers in particular to a kind of hoisting crane transverse double-connecting rod type carrying pin mobile mechanism.
Background technology
The box-shaped principal arm of present large-tonnage both domestic and external, super-tonnage car hosit generally adopts the telescoping mechanism of single-cylinder bolt, and this class telescoping mechanism mainly is made up of the bearing pins on bolt mechanism, telescopic oil cylinder, the arm and other duplicate.Bolt mechanism is the critical component of telescoping mechanism.
Bolt mechanism mainly is made up of the push-pull structure of retractable pin mechanism and bearing pins and both mutual interlocking gears, its working process is: 1, the tache motorice of bolt mechanism and telescopic oil cylinder is fixed, retractable pin mechanism stretches out pin at the afterbody of first telescopic boom, realizes that the tache motorice and first telescopic boom of telescopic oil cylinder interconnects; 2, bearing pins I is fixed on the first telescopic boom afterbody, by the pin-and-hole that inserts on the basic arm first telescopic boom is connected on the basic arm; 3, carrying pin inserting mechanism is extracted bearing pins I from pin-and-hole, and the basic arm and first telescopic boom are separated from each other; 4, the fixed end of telescopic oil cylinder is fixed on the basic arm afterbody, and other telescopic boom that at this moment will drive first telescopic boom and fixed thereon when telescopic oil cylinder moves moves simultaneously, has realized the flexible of arm; 5, the plug-in and pull-off device of bearing pins discharges bearing pins I when first telescopic boom moves to the pin-and-hole position of another appointment, bearing pins I ejects by the application force of retracing spring, insert in this pin-and-hole of basic arm, first telescopic boom is reconnected on the basic arm, thereby realized the once flexible of arm.Above action can circulate and carry out.If desired arm is extremely stretched state entirely from full reduced state action, then stretch the N telescopic boom earlier, the pin that will stretch is then regained, the tache motorice of bolt mechanism and telescopic oil cylinder simultaneously with the portion of N telescopic boom from and retract to the afterbody of N-1 telescopic boom, repetitive cycling is up to first telescopic boom is reached the position.6, for the consideration of secure context, mutual interlocking gear carries out mechanical interlocked to the action of the push-pull structure of retractable pin mechanism and bearing pins, stop mechanism and carry out dangerous play.
From above bolt mechanism working process, the flexible pin assembly of bolt mechanism and the plug-in and pull-off device of bearing pins and interlock move more frequent in the telescopic process of arm, and the service condition complexity plays critical effect in flexible action.By understanding, adopt existing technology can not adapt to the manufacturing status of our factory, so let us need develop a series of bolt mechanism products that possess independent intellectual property right to existing multiple bolt mechanism.
