Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiment, to the present invention
It is further elaborated.It should be appreciated that specific embodiment described herein is not used to limit only to explain the present invention
The fixed present invention.
Fig. 1 is the schematic diagram of the cross spandrel girder according to the present invention.As illustrated, cross spandrel girder totally includes vertical phase
The longeron 1 and crossbeam 2 of friendship, the wherein length of longeron 1 are more than the length of crossbeam 1.The intersection point of the two is located at longeron 1 and crossbeam respectively
2 midpoint, i.e. longeron 1 with crossbeam 2 be symmetrical axial symmetry, while crossbeam 2 with longeron 1 be symmetrical axial symmetry.
The diverse location of longeron 1 and crossbeam 2 is provided with multiple hangers.The first hanger of one pair of which 31 is located at longeron 1
The symmetrical position in two ends, and extend in the same direction perpendicular to the plane where crossbeam 2 and longeron 1.A pair of second hangers
32 are located at the symmetrical position in the two ends of crossbeam 2, and to extend in contrast to the direction of the first hanger 31.And the 3rd hanger 33
On longeron a bit, and with the identical direction of the second hanger 32 extend.A pair of first hangers 31, which are used to connect, drives a vehicle
On suspender belt, therefore cross spandrel girder have the first hanger 31 one side be alternatively referred to as above.A pair of second hangers 32 and the 3rd
Hanger 33 is respectively used to three faces of hoisting crane, therefore cross spandrel girder has the face of the second hanger 32 and the 3rd hanger 33
It is alternatively referred to as following.The second hanger of one pair of which 32 symmetrically slings the both sides of crane, and the 3rd hanger 33 is used to sling lifting
The other one side of machine, makes crane keep stable.So have the advantage that, when needs are in lifting motor spindle installation engine
Deng device when, while using the second hanger 32 and the 3rd hanger 33 so that crane keeps stable in installation process；Work as needs
When testing the balance of crane, it is only necessary to unload the constraint of the 3rd hanger 33, you can wave degree to have determined according to crossbeam 2
The balance of heavy-duty machine, and then targetedly adjust.Come compared to the different chain blocks of operation are needed in traditional adjusting process
The balance of crane is tested, cross spandrel girder of the invention effectively simplifies the process.
Intersect constituted right angle with crossbeam 2 in longeron 1 to set by multiple gussets 4, for strengthening cross spandrel girder
Mechanical property.
Preferably, the form that shell wraps up reinforcing plate is respectively adopted in longeron 1 and crossbeam 2, to ensure mechanical property
While try one's best mitigate cross spandrel girder weight.As shown in Figure 2.Have outside spandrel girder outside the longeron that steel plate is welded
Shell 5 and crossbeam shell 6, and it is welded and fixed multiple reinforcing plates inside the housing.
In the embodiment shown in Figure 2, reinforcing plate adds including being mutually orthogonal to one another the second reinforcing plate 72 and first of setting
Strong plate 71, and the two is both perpendicular to longeron 1 and the place plane of crossbeam 2.As illustrated, the height of the first reinforcing plate 71 is equal to
The width of the cross spandrel girder of its position, multiple first reinforcing plates 1 equidistantly distribute the arm in longeron 1 and crossbeam 2, with
And the both sides of position of intersecting point.The height of second reinforcing plate 72 be less than the first reinforcing plate 71, and the first reinforcing plate 71 be provided with it is fair
Perhaps the groove that the second reinforcing plate 72 is passed through.In the present invention, the first reinforcing plate 71 and the second reinforcing plate 72 pass through spatially phase
Mutually coordinate to ensure that the load-bearing property of cross spandrel girder.Second reinforcing plate 72 adds also cross adjacent two parallel first
Strong plate 71, so that cross girder structures are firm.Preferably, multiple second reinforcing plates 72 can be used to staggered through many
Individual the first adjacent reinforcing plate 71, so that structure is more firm.As shown in Fig. 2 the bottom of the first reinforcing plate 711, the first reinforcing plate
712 upper and lower part and the top of the first reinforcing plate 713 are respectively arranged with groove, and the second reinforcing plate 721 adds through first
The bottom of strong plate 711 and 712, while the second reinforcing plate 722 passes through the top of the first reinforcing plate 712 and 713.Being arranged such can be with
Suppress deformation of the cross spandrel girder in all directions by using reinforcing plate as few as possible.It is of course also possible to use other
Mode arranges reinforcing plate, to reach the purpose for strengthening cross spandrel girder.
The design parameter of cross spandrel girder each several part is referred to specific operating mode to set.For example, due to travelling crane hook it
Between safe operation distance cannot be less than 8m, the distance between a pair first hangers 31 can be set as 8.4m, can so protected
Demonstrate,prove to drive a vehicle using two simultaneously in the case where meeting safe distance and sling the hanger 31 of one end respectively.It is common using two drivings
The weight of a crane is shared, the crane suitable for superduty can not only be ensured, security is further improves.One
Common distance before the hanger on the crane of lifting is referred to the distance between second hanger 32, in the reality of the present invention
Apply in example is 4.4m.Reasonable disposition, which can be carried out, according to the weight of the crane of lifting has the hanger of appropriate load, in the present invention
In each hanger can carry 120 tons of load, the weight of crane is undertaken enough.
The present invention is only illustrated by taking hoisting crane as an example, and cross spandrel girder is equally applicable to other superduty machines
Lift process.The cross spandrel girder of the present invention not only eliminates the hanging apparatus such as chain block and suspender belt, saves running cost,
Lifting operation can also be carried out using two drivings simultaneously, superduty machinery can be lifted, and by effectively simplifying balance adjustment
Process and improve operating efficiency.
Embodiment described above only expresses embodiments of the present invention, and it describes more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
