Description
Technical field
The utility model relates to leveling and the turning gear of a kind of control apparatus of engineer machinery operation platform, particularly a kind of high-altitude operation platform.
Background technology
When aloft work, the leveling of operation bucket is assurance personnel safety requirements, adopts oil cylinder leveling mode, and transaction capabilities is stable, simple in structure, easy to maintenance.The revolution of operation bucket not only can increase scope of work, and workability is flexible especially, particularly aobvious its advantage of operator in narrow space.Along with the demand of client to this performance, rotatable operation bucket widespread use.
The length of dwindling complete machine is beneficial to machine storage, transportation and Vehicle Driving Cycle.The length of jib is the main design parameters that high-altitude operation platform can reach maximum operation height, blindly reduces the arm body lap of splice and can increase deflection deformation, affect arm body stability.But the growth of jib is closely bound up with the size of car load again.At present, the mechanism's mode that drives operation bucket to rotate by rotary actuator is that side is arranged.For making good looking appearance, leveling cyclinder is arranged in arm body inside, requires leveling bracket size less, but runs counter to operation bucket stability.
Utility model content
The utility model provides a kind of leveling and turning gear of high-altitude operation platform, solves car load length and the conflicting problem of maximum operation height.
The purpose of this utility model is achieved in that this device comprises: bolt, flute profile square chest spar, box-shaped frame, arc reinforced rib, arm body twisted point, leveling equipment, leveling cylinder twisted point, C shape rotary support, reinforced rib, rotary actuator, operation bucket, tank tower bolt, arm body and leveling cylinder; At a flute profile square chest spar of the each connection of two ends of box-shaped frame, all there is bolt at two ends at each root flute profile square chest spar, be connected with C shape rotary support and rotary actuator in the bottom of box-shaped frame, reinforced rib is arranged at the bottom at C shape rotary support and rotary actuator, bottom at box-shaped frame is connected with leveling equipment by tank tower bolt, a side at leveling equipment has arc reinforced rib, has arm body twisted point and leveling cylinder twisted point at the other end of leveling equipment, is connected with operation bucket in the upper end of box-shaped frame; On arm body twisted point, be connected with arm body, on leveling cylinder twisted point, be connected with leveling cylinder.
Beneficial effect, owing to having adopted such scheme, bolt, flute profile square chest spar, box-shaped frame, arc reinforced rib, C shape rotary support and reinforced rib form turning gear, operation bucket are connected to the top of turning gear by bolt rigidity, work the effect of lifting; Box-shaped frame is connected in the inner ring of rotary actuator with bolt, make second protection simultaneously connect with axle screw bolt and nut.The outer ring of rotary actuator is connected with tank tower bolt with leveling equipment, and turning gear drives operation bucket to do gyroscopic movement with respect to leveling equipment under the driving of rotary actuator; Arm body is by arm body twisted point and leveling equipment hinge joint, and leveling cylinder one end is fixed on arm body, and the other end is by leveling cylinder twisted point and leveling equipment hinge joint.Along with leveling cylinder does fore and aft motion, leveling equipment is take arm body twisted point as centre swinging, thereby operation bucket plays leveling effect.
Variable section square box shape leveling equipment and arm body, leveling cyclinder hinge joint, change by the stroke of leveling cyclinder, pulls operation bucket to rotate as the center of circle take the anchor point of this device and arm body, when any luffing of arm body, and operation bucket and ground level all the time; The welded composition turning gear of C type rotary support and lightweight square-box-shaped link span, circular arc reinforced rib can be gained in strength, and its top has been connected with operation bucket the effect of lifting; Leveling equipment is connected transition with turning gear by rotary actuator and plays operation bucket gyroscopic action.
Advantage: this apparatus structure is simple, lightweightization, stable performance and moulding exquisiteness attractive in appearance.Directly lift manned operation bucket, reliability is higher.Arm body compact arrangement, can increase the arm body lap of splice, be beneficial to jib stressed, reduce deflection deformation, be specially adapted to reduce complete machine length dimension, increase the type of operation height.

In figure: 1, bolt; 2, flute profile square chest spar; 3, box-shaped frame; 4, arc reinforced rib; 5, arm body twisted point; 6, leveling equipment; 7, leveling cylinder twisted point; 8, C shape rotary support; 9, reinforced rib; 10, rotary actuator; 11, operation bucket; 12, tank tower bolt; 13, arm body; 14, leveling cylinder; 15, nut; 16, axle bolt.
The specific embodiment
Embodiment 1: this device comprises: bolt 1, flute profile square chest spar 2, box-shaped frame 3, arc reinforced rib 4, arm body twisted point 5, leveling equipment 6, leveling cylinder twisted point 7, C shape rotary support 8, reinforced rib 9, rotary actuator 10, operation bucket 11, tank tower bolt 12, arm body 13, leveling cylinder 14, nut 15 and bolt 16 for axle; At a flute profile square chest spar 2 of the each connection of two ends of box-shaped frame 3, all there is bolt 1 at two ends at each root flute profile square chest spar 2, be connected with C shape rotary support 8 and rotary actuator 10 in the bottom of box-shaped frame 3, there is reinforced rib 9 to be connected with leveling equipment 6 in the bottom of box-shaped frame 3 by tank tower bolt 12 in the bottom of C shape rotary support 8 and rotary actuator 10, a side at leveling equipment 6 has arc reinforced rib 4, there are arm body twisted point 5 and leveling cylinder twisted point 7 at the other end of leveling equipment 6, are connected with operation bucket 11 in the upper end of box-shaped frame 3; On arm body twisted point 5, be connected with arm body 13, on leveling cylinder twisted point 7, be connected with leveling cylinder 14.Operation bucket is connected to the top of turning gear by bolt rigidity, work the effect of lifting; Box-shaped frame is connected in the inner ring of rotary actuator with bolt, be connected with axle bolt 16 with nut 15 as second protection simultaneously.
For reducing complete machine length dimension, operation bucket is arranged and flushed with leveling equipment, do not take complete machine size, guaranteeing under the condition that complete machine size is certain in other words, that arm body can be designed is longer, thereby increases maximum operation height.In order to reduce weight, flute profile square chest spar 2 and box-shaped frame 3 are all designed to square chest structure, and there is good stability.In order to guarantee to put motor 10 stress equalizations, C shape rotary support 8 flexibly connects by arc reinforced rib 4 and box-shaped frame 3, for increase C shape rotary support 8 Structural Strength Design skirt shape reinforced rib 9.Leveling equipment can swing in arm body inside in operational process, and proof strength does not relate to arm soma again, and leveling equipment is designed to variable section box type construction.
Variable section square box shape leveling equipment and arm body, leveling cyclinder hinge joint, change by the stroke of leveling cyclinder, pulls operation bucket to rotate as the center of circle take the anchor point of this device and arm body, when any luffing of arm body, and operation bucket and ground level all the time; The welded composition turning gear of C type rotary support and lightweight square-box-shaped link span, circular arc reinforced rib can be gained in strength, and its top has been connected with operation bucket the effect of lifting; Leveling equipment is connected transition with turning gear by rotary actuator and plays operation bucket gyroscopic action.This device need rotate on arm body inner side, so topology layout is had relatively high expectations.Directly lift again manned operation bucket, so reliability requirement is higher.
