The purpose of this utility model is to provide a kind of lorry-mounted crane three grades of telescopic outrigger structures, solves the problem of heavy tonnage lorry-mounted crane durability requirements.
The purpose of this utility model is achieved in that this telescopic outrigger structure comprises: Convenient table, the first Retractive leg, the second Retractive leg, the 3rd Retractive leg, the first front Assembly of pin, the first telescoping cylinder, the first rear pin shaft assembly, the second front Assembly of pin, the second telescoping cylinder, stretch out drag-line, reclaim assembly pulley, the second rear pin shaft assembly, reclaim drag-line, Assembly of pin and stretch out assembly pulley.The first telescoping cylinder one end is fixed on the Convenient table by the first front Assembly of pin, and the other end is fixed on the first Retractive leg afterbody by the first rear pin shaft assembly; The second telescoping cylinder one end is fixed on the first Retractive leg afterbody by the second front Assembly of pin, and the other end is fixed on the second Retractive leg afterbody by the second rear pin shaft assembly; Stretch out assembly pulley and be fixed on the second telescoping cylinder end, reclaim assembly pulley and be fixed on the second Retractive leg afterbody; Stretch out drag-line one end and be fixed on the first Retractive leg afterbody, the other end is fixed on the 3rd Retractive leg afterbody by Assembly of pin, and the centre is walked around and stretched out assembly pulley; Reclaim drag-line one end and be fixed on the first Retractive leg end, the other end is fixed on the 3rd Retractive leg afterbody by Assembly of pin, and the recovery assembly pulley is walked around in the centre; It is flexible in Convenient table that the first telescoping cylinder drives the first Retractive leg; It is flexible in the first Retractive leg that the second telescoping cylinder drives the second Retractive leg, and to drive the 3rd Retractive leg flexible in the second Retractive leg by stretching out drag-line and reclaiming drag-line simultaneously; The first Retractive leg and the second Retractive leg sequential telescopic, the second Retractive leg and the 3rd Retractive leg synchronization telescope.
Beneficial effect: owing to adopted such scheme, it is interior flexible at Convenient table 1 that the first telescoping cylinder 6 drives the first Retractive leg 2.It is interior flexible at the first Retractive leg 2 that the second telescoping cylinder 9 drives the second Retractive leg 3, interior flexible at the second Retractive leg 3 by stretching out drag-line 10 and reclaiming drag-line 13 drivings the 3rd Retractive leg 4 simultaneously.The first Retractive leg 2 and the second Retractive leg 3 sequential telescopics, the second Retractive leg 3 and the 3rd Retractive leg 4 synchronization telescopes.Both guarantee landing leg stretching efficient, also significantly improved the supporting leg span, reached the purpose of this utility model.
Advantage: by using three grades of telescopic outrigger structures of this lorry-mounted crane, significantly improved the supporting leg span, improved stability and the load-carrying ability of hoisting crane, guaranteed job safety.
