As shown in Figure 8, in the present embodiment, this is provided with locking part 211 to the first armed lever 21, when this is switched to the first armed lever 21 plumbness be parallel to each other, this is connected with a suspension hook 100 of hoisting crane the first armed lever 21, and by locking part 211, this is locked in this plumbness to the first armed lever 21.The form of locking part 211 can be one of them first armed lever 21 arranges one rotatable, be with reeded plate, another first armed lever 21 is arranged one protruding, when plate rotate to groove and projection in conjunction with time realize locking.During practical operation, first, first armed lever 21 is in open mode as shown in Figure 1 due to the backstop of the first limiting section 121, along with falling of suspension hook 100, the deadweight of suspension hook 100 makes this to the rotation close to each other of the first armed lever 21 to the plumbness be parallel to each other, suspension hook 100 engages with the first armed lever 21 automatically, and by locking part 211, first armed lever 21 is locked in this state, and then suspension hook 100 rises.As shown in Figure 5,6, when cross-beam body 11 is connected with the first armed lever 21, cross-beam body 11 connects two the first pallets 31 or two the second pallets 32, and cross-beam body 11 is lifted by crane by a suspension hook, is applicable to the test run lift heavy requirement that specification is less.
As shown in Figure 1, 2, this two group of second hanger 13 is along the longitudinally symmetrical setting of cross-beam body 11, each is organized the second hanger 13 and has a pair second hanging parts 131, this is to the setting of second hanging part 131 along the lateral symmetry of cross-beam body 11, and be positioned at the both sides of the first hanger 21, as shown in figs. 9-11, every a pair second hanging parts 131 and a pair second armed lever 22 pivot joints, make the second armed lever 22 can around second hanging part 131 pivotable in the plane of the transverse direction of cross-beam body 11.
As shown in Fig. 2,10,11, in the present embodiment, beam mechanism 10 also comprises the second limiting section 16, it is fixed on cross-beam body 11, when contacting with the second limiting section 16 in the second armed lever 22 pivotable process, the second armed lever 22 stop pivotable and be in mutually away from open mode or closure state close to each other.In the present embodiment, two the second limiting sections 16 are provided with corresponding to each second armed lever 22, when the second armed lever 22 mutually away from be switched to when wherein one second limiting section 16 contacts by this second limiting section 16 spacing (as shown in Figure 10), when the second armed lever 22 close to each other be switched to when wherein another second limiting section 16 contacts by this another the second limiting section 16 spacing (as shown in figure 11).Second limiting section 16 ensures that the first armed lever 22 launches the state be in Figure 15, ensures that suspension hook 100 can fall and fall after on the first hanger 12 and stops.As shown in Figure 9, in the present embodiment, the second armed lever 22 also establishes handle 221, for promoting the second armed lever 22 to closure state close to each other.Suspension hook is risen after second armed lever 22 is closed.Four the second armed levers 22 coordinate with two suspension hooks 100 can be suitable for sling 2 the first hanging baskets 31 and 2 the second hanging baskets 32, thus meets the test run lift heavy requirement compared with large gauge.
As shown in Figure 1, in the present embodiment, the bottom being installed on cross-beam body 11 of the first connecting portion 14 symmetry and near the two ends of cross-beam body 11, the bottom being installed on cross-beam body 11 of the second connecting portion 15 symmetry.
As shown in Figure 6, the first hanging basket 31 comprises entablatrance 311, arm-tie 312 and the first lower tray 313, and entablatrance 311 is connected with the first connecting portion 14, and in the present embodiment, the first connecting portion 14 comprises bearing pin, to be connected with entablatrance 311.What arm-tie 312 was vertical is connected between entablatrance 311 and the first lower tray 313.
As shown in Figure 5, second hanging basket 32 comprises link span 321, platform 322, wears axle portion 323, ladder 324 and the second lower tray 325, what link span 321 was vertical is connected between cross-beam body 11 and the second lower tray 325, wear the position that axle portion 323 is arranged at the close top of link span 321, for wearing a bearing pin between link span 321 and cross-beam body 11, platform 322 is arranged at the close position of wearing axle portion 323 of link span 321, and what ladder 324 was vertical is arranged between link span 321 and the second pallet 325.Before test run, staff climbs up platform 322 by ladder 324, to may stand on platform 322 operation and wears axle portion 323 and realize wearing axle.
Therefore, the connection of cross-beam body and first, second hanging basket existing is easy to realize.Can be connected with arm-tie by the entablatrance of the first hanging basket in advance, interfering with each other does not appear in the initial position (position in Figure 12) that arm-tie is in close to level.Second hanging basket has platform on top, realizes wearing axle by wearing axle portion, convenient and safe.
In sum, the special chain sling of test run of the present invention optionally coordinates with two kinds of armed levers with a beam mechanism.For the test mass requirement that specification is less, a beam mechanism and a pair first armed levers can be adopted, form that two hanging baskets coordinate meets; For the test mass requirement that specification is larger, a beam mechanism can be adopted to meet the form that the second armed lever, four hanging baskets coordinate with two, finally reach and meet the requirement of all specification hoisting crane test run lift heavys with a special crossbeam of test run and existing test mass hanging basket.Therefore, the special chain sling of test run of the present invention is combined by the suspension of multiple hanging basket, realizes the covering on a large scale of test run lift heavy, reaches the object meeting the requirement of multiple large gauge hoisting crane test mass, and can reduce cost of goods manifactured, easy to operate.
Although exemplary embodiment describe the present invention with reference to several, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Spirit or the essence of invention is not departed from because the present invention can specifically implement in a variety of forms, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claim of enclosing, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claim of enclosing and contained.
