Abstract
The invention provides a kind of two box type telescopic arm configuration, this jib is the multilevel arm of two box, and it is saved by arm and link span is formed, and same stages arm joint is connected by link span.The present invention sets up less parts at existing two identical jibs, connects into arm structure, greatly improve lateral stability by simple connection structure, increases load-carrying ability, practical.
Description
Technical field
The present invention relates generally to engineering machinery field, particularly a kind of two box type telescopic arm configuration.
Background technology
The jib of current car hosit or full Terrain Cranes is all that box type telescopic arm increases brachium by flexible box-structure, because it is overhanging beam, less stable, especially long-armed long time, more be difficult to control its amount of deflection, solution before strengthens its cross section and wall thickness or increase to have surpassed strut, but front a kind of method enlarging section and wall thickness can cause transporting over-wide, increase traffic cost; A kind of rear method makes jib change freely-supported mode into by cantilevered fashion, to some extent solve amount of deflection problems of too, but when needs telescopic boom is longer, the amount of deflection problems of too that this kind of mode can not change the long due to length of more than one-level arm and cause, institute can not tackle the problem at its root in both ways.
Summary of the invention
A kind of two box type telescopic arm configuration of invention, the insoluble amount of deflection of box type telescopic arm overcoming prior art is excessive, and cost is high, and not easily transport waits technical barrier, provides a kind of two box type telescopic arm configuration.
The invention provides a kind of two box type telescopic arm configuration, described pair of box type telescopic arm configuration is the multilevel arm of two box, and it is saved by arm and link span is formed, and same stages arm joint is connected by link span.
Described link span has two kinds, a kind of space truss structure being tubing and being welded into, as truss connecting device after welding with hinge ear; Another kind is the box-structure of sheet material welding, as box connecting device after welding with hinge ear; Add strength at the arm head of each arm joint of box arm and weld otic placode as hinge ear for being connected with connecting device.
Two jibs of the multilevel arm of described pair of box are symmetrical.
Beneficial effect: set up less parts at existing two identical jibs, connect into arm structure, greatly improve lateral stability by simple connection structure, increases load-carrying ability, practical.

Detailed description of the invention
Embodiment 1
For eight grades of arms, as shown in Figure 1 before box type telescopic arm is not yet flexible by two one-level arms 1, secondary arm 2, three grades of arms 3, level Four arm 4, Pyatyi arm 5, six grades of arms 6, seven grades of arms 7, eight grades of arms 8 are respectively by one-level arm link span 9, secondary arm link span 10, three grades of arm link spans 11, level Four arm link span 12, Pyatyi arm link span 13, six grades of arm link spans 14, seven grades of arm link spans 15, the hinge ear of eight grades of arm link spans 16 connects together, wherein stressed larger, the one-level arm 1 that amount of deflection is larger, level Four arm 4 place, its link span 9 adopts space truss structure, then this space truss structure and truss structure are cut with scissors ear 17 to weld, box type telescopic arm one-level arm 1 is connected to by bearing pin, main arm joint hinge ear 18 place of level Four arm 4, as shown in Figures 2 and 3, in other stressed relatively little position, adopt steel plate to seal into the structure of box, cut with scissors ear 19 with box-structure and weld, by hinge ear 20 place of pinned connection in other arm level of box type telescopic arm, as shown in Figure 4 and Figure 5, eight grades of arm 8 positions, this box-structure inside lining brace panel, stressed to guarantee.After box type telescopic arm has been connected with turntable, chassis etc., when entering mode of operation, by two oil cylinders with speed with Stress control two box type telescopic arm simultaneous retractables, after flexible as shown in Figure 6.
Embodiment 2
This invention is to provide a kind of jib of superhuge box type telescopic boom crane, and this jib is the multilevel arm of two box, is linked together by arm support connection device.Arm support connection device has two kinds, a kind of space truss structure being tubing and being welded into, as truss connecting device after welding with hinge ear; Another kind is the box-structure of sheet material welding, as box connecting device after welding with hinge ear 20; Add strength at the arm head of each arm joint of box arm and weld otic placode as hinge ear 20 for being connected with connecting device.Its effect is two the identical arm joints that are rigidly connected, thus the resistance to overturning of jib is increased.Implementation procedure is as follows, is linked together by existing two identical box Telescopic boom framves by described connecting device, and for stressed larger, the arm end of arm joint (as one-level arm) that amount of deflection is also large is added strength and is connected with space truss connecting device by bearing pin; And strength is added for the arm end of stressed relatively little arm joint (as secondary arm) be connected with box connecting device by bearing pin.Certain two jibs also can independently use according to actual needs.
Claims (1)
